Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe.
This seemed like a solvable problem.
Laboratory.love lets you crowdfund independent testing of specific products you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid's snacks, whatever you're curious about.
Here's how it works: Find a product (or suggest one), contribute to its testing fund, get detailed lab results when testing completes. If a product doesn't reach its funding goal within 365 days, automatic refund. All results are published openly. Laboratory.love uses the same methodology as PlasticList.org, which found plastic chemicals in everything from prenatal vitamins to ice cream. But instead of researchers choosing what to test, you do.
The bigger picture: Companies respond to market pressure. Transparency creates that pressure. When consumers have data, supply chains get cleaner.
Technical details: Laboratory.love works with ISO 17025-accredited labs, test three samples from different production lots, detect chemicals down to parts per billion. The testing protocol is public.
So far a couple dozen products have received some funding, six products have been fully funded (five product results published, the sixth is at the lab as I write this!)
You can browse products, add your own, or just follow specific items you're curious about: https://laboratory.love
Looking at the tofu reports, I really don't know what to make of them. Is there a way to give more meaning to them for the average person? Also, I'd love to see a sort by "almost funded" option.
I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.
I LOVE this idea. Tangentially, a more pimitive case: in trying to recycle or reuse jars or carboard containers food comes in, I wish there was a simple service for ranking brands. For example, some jam jars have labels that can be immediatey removed - others tear and stick to the jar. Similarly, some brands use excessive plastics and packaging, others less so.
I keep telling my euro-friends that food and health regulation could potentially be enforced by the free market more effectively than by corruptible government, and this is a perfect example of this.
I'd want to see all products I can buy in there, with all possible chemical, ingredients and nutrients, and clear indications of good/bad, a little bit like in Yuka. You should partner with them maybe even!
I agree "enforce" is a poor choice of words. It does not need to be "enforced" using state violence if any consumer can access facts with such transparency. What's missing today is this level of transparency with which the market will just naturally benefit to producer of sane and safe goods in a much more natural way.
Also, speaking of the "more free market in the US", my answer is that you don't hate capitalism, you hate crony capitalism.
> you don't hate capitalism, you hate crony capitalism
What distinguishes this from 'you don't hate socialism, you just hate every so-called socialist government'? I know this seems like lazy smartarsery, but I'm genuinely curious whether you think we have real-world examples of countries doing capitalism right -- and, if not, why that's not a bad sign in the same way that a dearth of examples of socialist success stories is a bad sign.
Wow, great idea, simple website and hopefully a positive impact, not often you see all three in one project :) Good job!
I'm guessing it's limited to US products and US labs? Would love something similar in Europe and/or EU, but it isn't clear if you're limited to US/North America right now, would be nice if it was a bit clearer up front :)
Really cool project. A quick note, I had to dig in your FAQ to find your definition for LOQ:
> "What does 'LOQ' mean in your results?
>
> Limit of Quantification (LOQ) is the lowest concentration we can reliably measure. Results below LOQ are marked "<LOQ" - this doesn't mean zero, just below our measurement threshold."
IMO this definition should be on every results page, since most of the pages have more LOQs than anything else.
This is great. I thought about a different model even before plasticlist: make a subscription and test various products, but people will have a number of upvotes based on their sub streak. They vote for food to test, and then you show results to everyone subbed. Kind of like what examined does, but they do deep dives into medical topics for subs. I think this model will work better than the one you currently have. Awesome project anyways!
It is extremely weird to me that countries don't do that on taxpayers money and show the results publicly, this is what they should do.
I definitely considered a voting mechanism, but there are a few million active, buyable CPG UPCs in the U.S. at any given time. When conducting some basic market research for this project, I found that most people are only willing to pay to find results about the specific products they care about.
This is great. We definitely need something like this.
Where are the safe levels limits to interpret test results? This would be a small addition that would make any of the results interpretable. I had to open the PlasticList website to get the baseline safe thresholds for each chemical and to do some rough approximations.
What would be a good strategy to prevent companies from cottoning on to this and gaming the system? They could for example change packaging on production runs for a product that’s undergoing laboratory.love funding campaign.
It's an interesting thought. Companies do change packaging somewhat regularly. However, the underlying skew usually remains the same. Changing the packaging and/or the SKU is very expensive. It's probably cheaper and more beneficial to your company to do your own Plastic Chemical testing and get ahead of the problem.
My suspicion is if this was gameable, this would be a solved problem by a number of companies. The truth is there is no single simple or even hard step to take, it’s mostly like numerous steps that multiple actors would need to do.
I suggest you xpost to Bryan Johnson's Blueprint community. I think might help you get a lot more food tested. That community is probably ICP and also can amplify the message.
Folks at Blueprint actually reached out to me when they saw this project at the beginning of the year and essentially tried to acquire it by hiring me as a contracted engineer. I politely declined.
Blueprint Quantified, which is linked in the below comments, went live after these conversations. Imitation is the sincerest form of flattery.
This is so incredibly important, well done. The problem of our food being steeped in plastic hits the news here and there, but it should be front and center in my opinion. Testosterone has been plummeting for decades and it scares the heck out of me. The hormone whose job is "form goals, shrug off failure, and try again!" is being destroyed and corporations are given a free pass to pump us full of phthalates and bisphenol. It's infuriating.
And anecdotally, I've still been forming goals and shrugging off failure five years into suppressing most of my endogenous testosterone with exogenous estrogen
Well that's great for you, but I was making a generalized statement about the role of testosterone, scientific data showing huge decline, and more and more studies linking it to plastics. We can't just alter a key hormone within the span of a few decades and shrug it off. My levels are great for a 40 year old
And yes there are certainly other factors, but that's not what the original comment was talking about?
I don't know if it's a joke, in the EU we do enjoy a lot more strict regulations, good and bad sometimes, but to me the US system just seems more 'reactionary' rather than proactive.
It is ABSOLUTELY a joke. Downloaded Oasis app last night. My ‘Whole Foods’ water, ya turns out I’m drinking levels above what I should of arsenic, amongst other nasty shit

The product label images loading on the homepage are huge right now. They are displayed in 128px * 128px box but are about 2 MB in size each. May be generate resized versions at build time and use <picture> tags?
I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet).
It uses 4k stereoscopic capture and bunch of ML models to match bone position with sub-millimeter precision. The surgeon screws a metal base piece into the bone, and we detect where that is in space. Then, a Stewart Platform adjusts another part that is placed onto the base. The robotic adjustment allows the base to be placed in a ballpark area, with the robotically-adjusted piece oriented in the exact spot where the surgeon needs to cut.
The net result is a robotic system that is many times cheaper than the least expensive incumbent, decreases surgery time significantly, reduces error, and basically "just works" as opposed to requiring a ton of training. We are debuting at a tradeshow in October.
This sounds awesome! Can you tell me more about what kind of expertise do you need to develop such a system? As in the most important knowledge one most have to be able to work on such a thing
Thanks, buddy! I'm having fun. There are a few sides to it. There are the actual physical surgical tools that you have to design, test, and manufacture. Then there's the robot that adjusts those tools. That stuff is a lot of CAD and 3D printing. The camera is a big deal and it's a ton of work to get that right. Then of course you have all the software, which is a slew of computer vision models that operate on a local computer in a careful dance of resource orchestration. The software has a lot: UI, grpc services, ml models on containers, inverse kinematics for calculating robot position, hardware interfaces, etc. Then there's a bunch of regulatory, validation, compliance, etc.
To answer your question about expertise, it really depends on what you are interested in. We have some dedicated mechanical engineers with medical device experience. The software is handled by a few computer vision and full stack folks. So there's different skillsets.
I'm a bit of a journeyman and as a result, I am decent across all of it. I always did software and went where the wind blew. It's been 20-something years since I graduated so I've seen a lot. About 10 years ago I got a job I was totally unqualified for, which was R&D for a company that made lab equipment for testing gas and oil. I was solo and had to learn all the mechatronics stuff - CAD, microcontrollers, electronics, etc. Check out this video: https://youtu.be/MA6hnyXx4p4. That specific experience allows me to be the glue in our engineering org.
To work here, you don't need medical experience. We have plenty of that. One of the cool things about engineering, especially software engineering, is that you can float around between verticals. I've learned all about media, finance, petroleum, insurance, waste disposal, etc. The skills translate. If you are purely software, I recommend picking up an Arduino and some motors and building something like a simple pan/tilt mechanism with an accompanying mobile app. Just do it. It might inspire you. I think curiosity and enthusiasm are the most valuable traits one can have.
That seems like a long journey. I think playing with Arduino is a perfect way to get started on the interaction between software-hardware. Thanks a lot for your answer!
VR training hasn't really stuck in ortho training. It's legit and people do it, but it's a distant second to doing it live. I haven't seen that much of it, but from what I have seen, the fidelity is quite low. It would be cool to see what a good game studio could produce.
Doctors, like most people, don't like stuff on their head. Plus in ortho there is a lot of feel to it. It's often referred to as "carpentry". The docs I know, especially those with experience, would prefer a video and a cadaver lab. Even that's a lot to ask because they are so swamped. In every surgery there is a rep from the implant company, and those reps are really the ones doing the training.
So there is certainly potential but it's just not to the point where people are excited about it.
Used to work for a major implant company, we had a cadaver lab at company headquarters and flew in doctors for training. The rep in the OR is mostly just for support. They carry in a bunch of hardware in case the doctor needs to pivot midway through, they may need different sized screws or something. They can show doctors how the device is meant to connect together without bone/tissue but they often have little to no medical training, they are sales representatives.
Hey there, thanks for writing. For those who don't know, the sales reps have to carry in racks and racks of parts. Most go unused but the last thing you want is something to go wrong and not have the piece you need readily available.
I've been in many different ORs and I've found that the rep's knowledge and level of participation varies a lot. Some of these reps have been working with the same products for years, the doc fully trusts them, and could probably perform the procedure themselves. Others not so much.
This sounds about right. My time in the industry, I always remember our top selling rep was basically royalty at the company he drove so much volume - but, he was only about 22 and never finished college or had any actual medical training. He just grew up with a surgeon Dad, country club, etc. and had deep connections with a lot of surgeons by virtue of this. He was also very charismatic and a good salesman, just not the guy you'd want training your surgeon before they fused your spine.
This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS .
It gets ~80K MAUs and just slowly and consistently is growing organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun project.
I got into it because I was interested in the technical challenge of registering GPS to maps which are very warped compared to reality, like very old maps or illustrated tourist maps.
Hey Brendan! I also would love to add Canadian maps, it's been a huge request from my users and something I've been wanting to focus on all year. A big challenge I have in bringing the service to new regions is just data access, both to raw hi-res map imagery as well as to satellite, LiDAR, etc so this is on my todo list to begin digging into what the Canadian government offers. Brave new world for me
Nice project! The National Library of Scotland has a nifty tool focused mainly on the UK and Ireland that does something similar (with a paid print service attached):
https://maps.nls.uk/geo/find/marker/
Really cool! I built the website for an antique maps dealer (Dat Narrenschip) when I was 15 or so and fell in love with antique maps. It's still up and running but now on Shopify.
Over the years I experimented a bit with leaflet.js and thought of overlaying maps too so you can navigate maps through time, but quickly realized it was super difficult. Kudos for setting this up!
If you want to expand to other regions, or chat, or get access to high-res scans, let me know. I think plenty of old maps sellers would love to sell their maps this way.
Have you looked into speaking with the various SHPOs in each US State/Territory?
I've worked with several of them a fair bit and they have a ton of old maps hidden internally. Especially for small, specific areas of the state, like historical districts.
That's nice! I have some GIS data of my country it was pretty detailed, it may be outdated now, but covered a good amount of administrative details. If you are extending and need some data on Bangladesh, I can send you
That is awesome. Of course you can bolt LLMs on to any product, I'm thinking AI reviews of (historical) local businesses to give it that google maps feel.
Around 90% of the maps currently on the site are from the US government (USGS). The last 10% are from public institutions and libraries and this is the newest segment that I'm actively working on growing. My hope is to flip this ratio with time.
I also have a few partnerships in the work with some private collections but those have proven trickier to actually get to a "yes". It also involves a lot of bespoke work to process and ingest each individual source so I'm not focusing as hard on this type of sourcing anymore.
I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups.
Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those services provided all the information on a book. One might provide the series, the other might provide genres, and yet another might provide a cover with good dimensions, but none provided everything, so I decided to work on something of my own (called Librario).
While Shelvica is the focus, Librario could become its own thing in time, so I don’t mind the sidetracking.
I also plan on having a “ISBN Search” kind of website that feeds from that database as a way to let users search for information about books, which then feeds the service’s database, making it stronger for Shelvica.
I open source everything I make, but I’m still wondering if these will be open sourced or not. I’ll probably go with the EUPL 1.2 license if I do decide on open sourcing them.
[1]: My wife and I have a personal library with around 1800 books, but most applications for management are either focused on ebooks or choke with this many books. Libib is the exception, but I wanted a little more.
Didn’t have the time yet, but it’s on my todo list. I have extractors for Google Books, Hardcover.app, and ISBNDB already working, and Amazon, Goodreads, and Anna’s Archive in the todo list.
I do plan on including a link to the book on Anna’s Archive in the “ISBN Search” website. At least to the search page with the filters already filled.
Hey I'd like to learn more about what you're doing. I'm working on a tangentially related service but focusing on audiobooks. One big stumbling block I ran into early on was trying to find something close to a unified ISBN datasource.
If you're up for it, shoot me an email at charles@geuis.com.
Service isn't online yet, but you can find me on Sourcehut[1] and on GitHub[2], where I'll probably be posting the service soon. You can also email me[3] if you have a request or a specific use case I might be able to support.
I attempted something like this because I wanted a good books search service which provided me at-a-glance information I needed from Storygraph & Goodreads. The main things I look for when I search a book is genres/Storygraph's "moods", number of pages, whether it's part of a series, rating across services & how much does it cost.
The algorithm to decide what to merge is the hardest part, in my opinion, and very basic right now. Eventually, I wanna try doing something with machine learning. Definitely a fun thing to work on, though.
Having a full time job and a baby to take care of make progress slow, but I should have the website ready soon. Shoot me an email and I can let you know when that happens.. email is on my profile.
I'm super curious if anybody will pick it up and do something useful with it. This was a couple of years of my life and I absolutely loved working on it but having a child put a hard stop to such entertainment for many years. Now, a good 30 years later I finally found the time to resurrect it.
I'm not sure yet if I am going to do more work on it or leave it as it is, it's good enough to give someone new to OS development a running start and a foundation to build on.
In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible.
Our first dinner was with 13 friends and has since grown into a group of just about 1,000 members. Last year we generated around $140k for local restaurants on off nights (dinners are on Tues and Wed when business is slow).
Now we are working on evolving into more of a lifestyle brand for people who love food. I'm currently working on our clothing line and new site, which we quietly launched a few days ago (there's still a few odds and ends to finish): https://www.deadchefssociety.com. Would love any feedback!
That's such a great idea. Especially since you're also helping the restaurants out. Nowhere near that area otherwise I would've petitioned straight away
I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy.
I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.
That is so neat. I built something a little bit like this for a simulator of a 3D portal mill. Trying it on real wood got expensive fast so for debugging runs and trials of designs I would run a simulation where the toolbit would hack out the shape out of a three dimensional array of voxels. This was then displayed using a very simple engine built with PyGame. I got a lot of use out of that and it saved days (and a small forest).
Great to see something along those lines but with much better visuals.
Yeah, just render to texture, with one instance of cpu readback (for generating voxel data). There are a couple features I'd like to implement that require 4.3, but I'm pretty committed to the bit at this point. Maybe one day I'll have some optional features.
The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circuitscript tool (currently only the desktop cli tool) is able to generate KiCAD netlists and this can be imported into PCBnew.
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so (because this is also part of the design process) and to encourage code reuse.
Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!
As a big openscad fan I love the idea of designing circuits with code.
I do wonder though about designing circuits vs designing schematics. I see you have ‘wire down 100’ making it a more visual language than defining the nets. Be interesting to separate the schematic layout from the nets, so rule base schematic layout can then be applied.
You can actually skip all the wire commands and still generate a valid netlist, however the schematic might be a bit hard to decipher if there are many components!
I did explore automated layout algorithms for components in the schematics, however the readability and flow of the schematics might not be ideal, depending on what the algorithm prioritizes.
In the end, I realized that the actual layout and arrangement of the schematic itself was critical in the overall understanding. That was when I decided to add the "wire" command and give more control back to the schematic designer.
In the future, I do plan to add some automated way to generate these "wire" commands for automated layout. If the designer ever chooses to edit this automated schematic layout, he would be able to edit the wire commands for finer control.
In the end, I do believe that the visual part of the schematic plays an important role in understanding it. I, too, have spent hours puzzling/being misled by poorly drawn/disorganized schematics. Especially during troubleshooting or creating an updated revision, having a good understanding of the schematic saves time.
One of the aims of Circuitscript is to make the visual part easier, so at least more time can be spent thinking and organizing the schematic itself.
Yes, that's true, right now you have to manually press on the Save button. I will update the online editor to auto-save after some time and probably also prompt the user to save before navigating as well too. Thank you very much for your feedback!
It prioritizes accessibility, longevity, performance, and simplicity.
With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.)
Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode.
All form controls are form-associated via ElementInternals and work with native validation APIs (required, pattern, etc.).
Dialogs, popovers, tooltips, etc. use Popover API for top-layer access without having to portal or hoist.
Some of the more fun components include: Joystick, Stamp, Mesh Gradient, Flip Card, Random Content, Intersection Observer, Typewriter, Lorem Ipsum, Slide Activator
The library is free for personal, educational, non-profit use. Commercial use requires a license.
I especially liked the browser frame page. It’s so beautifully crafted. I would move the inception example onto the homepage and up on the examples as it is a good example of love put into the whole project and its execution. https://quietui.org/docs/components/browser-frame#embedding-...
Thank you! For the components, I use the Custom Elements Manifest Analyzer to get data from JSDoc comments and TypeScript. This populates properties, events, methods, slots, etc. All the examples and other pages are hand-made. Docs are generated with 11ty.
The idea is to have deterministic text transformations generated by AI, which can be saved and reused later to avoid incurring/piling up LLM-call cost and hallucinations.
This solves my own pain points when I wanted to clean up some text with non-trivial requirements which takes quite some time to figure out with normal text editor's find-and-replace + regex.
Yes, you can write your own code/put LLM generated code in an IDE and do the same thing. However, I just wanted to create a trivial way to generate/save/execute (safely in a local lightweight VM) code to transform my text.
Working on orbital dynamics code for my PhD in astronomy, written in rust, it can accurately calculate the positions of all asteroids/comets to within a few meters. Today I am adding a new numerical integration method which should enable me to predict orbits from observations.
Its an implementation of a pretty standard integrator used by astronomers informally called "RADAU", but it is not exactly the same RADAU you would find elsewhere. Basically it is about as good as you can typically get for multi-step integrators, tuned for speed not precision though.
Note that how the code is laid out you cant really simulate non-solar system masses. Its really aimed at massless objects in the solar system, your 3-body simulations are actually quite difficult to do given the design.
I suggest the appendix of the arxiv paper if you want to see some of the math required for solar system objects beyond simple Newtonian gravity (like Relativity corrections). I wrote that section specifically because I found it a pain in the ass to source those equations in literature.
I'm working on Typegres, a new data layer for the modern stack (TypeScript + PostgreSQL).
My take is that for years, ORMs have hidden the power of PostgreSQL behind generic, database-agnostic abstractions. This made sense in 2010, but now it's a bottleneck.
Typegres rejects this. It's a "translator, not an abstraction," designed to express the full power of PostgreSQL (all statements, built-in functions, etc.) in a type-safe TypeScript API.
The latest killer feature my take of "object-relational mapping done right": class-based models with methods that are actually composable SQL expressions. This lets you extend your tables with expressive logic and fully-composable relations.
I'm personally not a fan of query builders for SQL. it's already a defined language, why are we trying to move away from queries? On top of that SafeQL is only a dev dependency, there's no abstraction. it gets ran through any query client you want
Thanks for the great points and link to SafeQL! I'm a big fan of its approach to bringing type safety to raw SQL strings. For static queries, it's a fantastic solution.
My take is that while "Just use SQL" is healthy pushback against heavy ORMs, a good query builder solves two fundamental problems that raw SQL can't in the application context:
1. Dynamic composition: A query builder is the macro system that SQL is missing. The moment you need to build a query programatically (e.g., conditional filters or joins) you're left with messy/unsafe string concatenation
2. Handling Relations (and other common patterns): Using raw SQL, a complex query with JOINs returns a flat list of rows that now becomes the application's job to properly denormalize. It greatly reduces cognitive load to think in terms of relations, not just join conditions.
Again, showing is stronger than telling. To illustrate, I'd urge you to go through the first couple of examples in the playground and think about how you'd express them (e.g., the composability of the "example1" query) in something like SafeQL: https://typegres.com/play/
Neat idea. Would you say that biggest difference from something like Kysely is the focus on extracting common calculated SELECT targets into methods that can easily be accessed when querying? Or perhaps it's more thorough with providing TS versions of all the SQL syntax available? The list of reference fields/methods in your docs is certainly massive.
First off, I'm a huge fan of Kysely and it's a massive source of inspiration for Typegres.
You've nailed the two big differences:
* Architected for Business Logic: The primary innovation is the class-based model. This is all about co-locating your business logic (like calculated fields and relations) directly with your data model. The cool part is that these methods aren't just for SELECT; they're composable SQL expressions you can use anywhere: in a WHERE, an ORDER BY, etc. The goal is to create a single, type-safe source of truth for your logic that compiles directly to SQL.
* PostgreSQL-Native: The other fundamental difference is the focus on going deep on a single database rather than being database-agnostic. That massive list of functions you saw is a core feature, designed to provide exhaustive, type-safe, and autocomplete-friendly coverage for the entire PostgreSQL feature set. The philosophy is to stop forcing developers to reinvent database logic in their application code.
Philosophically, it's a shift from composing type-safe SQL strings (like Kysely, which is brilliant for its WYSIWYG approach) to composing SQL expressions as if they were first-class TypeScript objects.
I've been making and selling my electronic social battery pin badges for a while now (https://hortus.dev/products/social-battery) and I'm expanding the range with seasonal versions like a Christmas mood badge, and a halloween themed ghost badge that's coming soon. I'm lucky enough that these projects have gone down well and are making enough money to fund some more complicated (and expensive) projects that I wouldn't have otherwise had the guts to try. Currently I'm working on an RGB digital sand timer with customizable timing sequences so that you can use it for things like the pomodoro technique - I have a working prototype and at the moment I'm experimenting with interfaces for setting the sequences. I wanted to use a combination of buttons and an accelerometer for this but it's not as intuitive as I'd like so I may end up making a small smartphone app to configure it.
Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics.
I've been playing guitar for a little under 6 years and ran into the common problem among many intermediate guitarists fall into, which is stagnating into a plateau at a certain BPM.
The most effective solution I've found is to take the top speed hit playing a chunk of a lick and simply increase it 20-50 BPM past that limit, attempting one's best to stay in tempo. Regardless of how sloppy it sounds. Then roughly halve that increased addition of BPM, it will become relatively easier to play. For example, if you are stuck at 120 BPM, upping it to 150 BPM with sloppy attempts, then dropping it back down to 130-140 BPM.
I've gone cleanly from alternate picked 140 BPM triplets to 220 BPM triplets in two months after being stuck at 140 BPM for over a year with this method. Sometimes even hitting 280 BPM triplets when I have the focus and time for it.
Even then, I want a more consistent, and variable way of customizing a practice session using a metronome from a hobbyist perspective without using a DAW. With a simpler interface for doing so. As well as encourage with said method above for other guitarists in the pursuit of speed.
When I was 14 I would have wanted to "shred at 220bpm" but today I wouldn't get my wallet out for that. What I really would pay for is help getting into the pocket.
Anyone who can read a guitar tab can play the notes of "Superstition" by Stevie Wonder. But simply playing the notes against a metronome sounds mechanical -- the song only comes to life when you get the timings right (both the note attack and decay have to be timed for a "swing.") A good swing will practically force your audience to start dancing to your music -- it's magical! But it's very difficult to learn because regular metronome practice won't achieve it.
If you're measuring "rush and drag" against a straight metronome, could you also measure against a swung time, perhaps against timings extracted from in-the-pocket songs we know and love?
> When I was 14 I would have wanted to "shred at 220bpm" but today I wouldn't get my wallet out for that.
That's fair, essentially why I put "shred" in quotes originally is that shredding guitar isn't necessarily playing fast. You laid out a nice example with Superstition for that.
I don't see why that couldn't be implemented in some way (accenting specific notes and different sustain times).
What would be difficult is quantifying note attack exactly for XYZ's riff sections. I.e., what constitutes a relative baseline pick attack and the target pick attack. If we are using a float and define the "normal" attack as 0.5, then how do we know, for example, the first or fifth note in the iconic Superstition riff is 0.85? Is it empirical?
Either way, that is a lovely insight I will consider. Matching another guitarist's intonation down to a tee can be extremely difficult, but very rewarding.
If you load a groovy song in Audacity you should be able to see these inter-note delays.
Another factor that affects rhythm is note duration relative to the tempo -- you'll want to measure that too.
> Matching another guitarist's intonation down to a tee
I suspect if you study a few groovy songs you'll find there's just a slightly different note grid that's common to these songs (there could be more than one grid!) Teaching this grid (rather than teaching one specific song) will help the student learn to shift notes away from the the mathematical metronome placement. This skill will equip many of them to mimic the feel of their favorite artist by ear.
I see what you mean now. I interpreted note attack as pick attack, which is traditionally defined as how hard a given note is played with a pick.
Yeah, swing usually has uneven subdivisions. Funk is almost always syncopated, and depending on the style, can be a mix of syncopation and swing.
This goes back to how you noted simply using a metronome will give that mechanical, or even a soulless characteristic, to playing a piece which inherently has a soulful quality about it. And with respect to intonation, there's a lot more that goes into that than just timing it right (how hard fingers are pressed on the fretboard, the pressure between fingers holding the pick, the angle of the pick, where the pick strikes relative to pickups, the pick attack, accenting notes, etc.)
I do love this idea of being able to apply some "in the pocket"/"swing" deviation to a metronome sequence. I agree with you that it adds that magical musical quality that people would instinctively dance to.
Accuracy indicators for rushing and dragging are very useful, but equally interesting would be an indicator that checks for a consistent peaks, so every note is played with equal volume. A dream would be if your app can detect differences in sound (fingernails occasionally scratching the string, fretbuzz).
Is there any way to get notified when your app is done, or do you have a name for it already so we can search for it in a couple weeks?
Love those ideas, would be awesome for really nailing down consistent tones. Latter one would be fairly ambitious for me but I'll keep it in mind for future improvements.
Just published the waitlist[1], the app will be called ShredBlocks.
Great instructional video. First place I learned E natural minor with his scale fragments section.
Yes, not a new technique by any stretch of the means. AFAIK John Petrucci takes a less aggressive approach with raising BPM. Funnily, Shawn Lane goes into a very similar methodology >30 years ago[1].
Unfortunately not a sequencer, which would be a programmable set of a series of blocks with different tempos, time signatures, subdivisions, etc., played in single sequence.
At least a couple more weeks. Hopefully less than a month out from now.
I have most of the UI done for sequencing. Workflows for speed building and metronome sequencing will be completely free, which is also a top priority for me to get out the door first.
Release engineering for FreeBSD 15.0-RELEASE. Major releases are always a lot of work, but this is probably the biggest release in 20 years due to the new base system distribution system landing. (We're switching from "here's a tarball containing everything" to "here's 500 packages", with resulting changes in the build process, download/update mirrors, installer, etc.)
Given that this is a major release, there are fairly wide error bars on that; it could be as much as 3 weeks earlier if the first release candidate turns out to be perfect, and of course it could be later if things go badly (but I very much hope to get it out by the end of 2025).
Definitely a massive job. Some FreeBSD developers have stepped up to volunteer tremendous amounts of help (and also the FreeBSD Foundation has paid staff helping out with parts of this) but my best guess is that I'll be spending around 300 unpaid hours making this release happen; I've been doing pretty much full time hours on this in September and I'm really hoping that once pkgbase moves from "need to implement the stuff which isn't implemented yet" to "need to iron out some bugs" I'll have time for other things... like my paid job, Tarsnap.
I’ve been suffering from migraines for the past year and the health system hasn’t been too helpful in diagnosing why. I’ve got some meds, but they’re expensive and not without side effects. So I’m building an app to try and figure out how to avoid the triggers in the first place.
Sort of like a digital bullet journal. You setup some rows of events you want to track, then just tap for when/if that events happens. It’s already helped me spot certain triggers for my migraines, which I can now minimize. My wife has been finding it helpful to diagnose sleep problems. I think it might be super helpful to others with trying to understand lifestyle choices and how it impacts their wellbeing.
About to roll out the beta. Hoping to have a full release by the end of the year.
It’s my first iOS app in 8 years! Learning SwiftUI after UIKit has been quite the shift.
I also created a grid for habit tracking (for chronic pain mgmt). Day of month across the top, all the things I'm supposed to do along the side. Something to share and discuss with my care providers.
Mine's just a spreadsheet that I tweak and print every month. (Then added to my discbound clipboard organizer, that I bring everywhere.)
I haven't had the gumption to digitize my effort. I really like the physical check lists. Though I've wondered how a hybrid solution might work. eg vital signs added automatically to digital version via Health.app. eg scan printed copy and magically fill in the digital version.
That’s precisely how I started too! But opening the spreadsheet on my phone to try and log something got to be tedious. Especially while actively having a migraine. I figured an app could ease the difficulty a lot.
Oof, 4 years living with that, I’m so sorry! It’s been so frustrating not knowing when/if I’ll have one, regaining some amount of control eases the pain a bit.
On the side, custom coloring books for kids using nano banana, started with a project for my son, and its a little janky for some photos but have had some interest already: https://bespokebooks.io. I think it needs to be a phone app to really work for most people though, so that's next on my to do list besides some prompt tweaking.
I think there are a lot of really fun projects possible now in the child book creation space, particularly as you build tools that they can use themselves (like adding voice interfaces to building a book or story).
This is outside my 996 job of AI Agent/Assistant infra + ops :)
Currently using Lulu because they have a developer api and allow printing a single book programmatically, many places I found either didn’t have an api or required a min order of books that isn’t needed for a one off custom design. https://developers.lulu.com/home
My hope for this project is to get enough demand that I have an excuse to figure out a printing option myself and buy some new equipment :)
This is truely awesome and reminds me of the project that was making a litle one story book with the child as the main character. It was at least a couple of years ago I think.
I'm working on Small Transfers (https://smalltransfers.com/), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers.
You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets.
If combined with subscriptions, the pricing can work similarly to mobile plans, where monthly plans become cheaper above a certain usage threshold.
Looking for more developers to try it and share feedback.
Flattr was a micro-donation subscription service where users set a monthly budget that was allocated to creators.
Small Transfers is for usage-based billing of online services and APIs. There is no monthly budget, wallet, or pre-funding. Customers are charged only for actual usage.
Please consult how "blik" works in Poland. It requires a bank cooperation, but it ultimately became a standard here for payments as an alternative to debit/credit card payment.
BLIK is a bank-backed payment method used at checkout.
Small Transfers is an API for a merchant to charge a customer tiny amounts (as little as $0.000001), which are batched into a single card charge via Stripe.
Customers do create an account and provide a payment method, but they don't pre-fund or hold a balance, and they don't initiate a payment. Small Transfers is an API that allows merchants to charge very small amounts programmatically. At the end of each month (or earlier, if a threshold is reached), we charge the customer what they owe. This makes the tiny charges viable and avoids death-by-$0.30.
It's not a PayPal remake, since there are no wallets, no P2P transactions, and no stored funds. In addition, Small Transfers allows very small charges (as mentioned above), and provides customer OAuth and spending caps.
If a customer's balance is under $1 at the end of the month, we delay charging them for up to 60 days and send email reminders. If it's still under $1 after 60 days, we charge at least $0.50 and credit the difference (after fees) to their account for future use.
From what I can find, Gripto was a cryptocurrency platform for viewing holdings, market info, and relevant news. It seems that the service was retired in late 2018.
Working on a webapp for critically think with others about a problem.
The idea is that you build a diagram that contains all the details about the problem and people's thoughts on it, and it's organized in such a way that it's easy to just keep refining, down to the smallest detail. So you build this concrete, shared understanding, and move it forward and forward, until hopefully y'all can make some best decision to improve the situation.
There's a lot to do. Currently working on UX to allow hiding intermediate nodes and still have indirect edges drawn. Want to add an LLM integration to generate/update diagrams via natural language, which I think will help a lot with usage barriers to using the app.
I wanted something similar for a worldview. I want an app where I can dump all the things that actively go into shaping my worldview and then when someone wants to know why I think the way I do, I will share them the link of my worldview board. We are not famous people to have our memoir written but this is another way to peek into minds of strangers.
That's a cool idea. Seems like there would be a ton of things contained in an individual's worldview, that it'd be hard to build all of it up. Perhaps when you encounter something that makes you think of some core philosophy, you note it and the philosophy, and eventually there would be a loose picture that forms amongst all the relations.
Certainly would be helpful for trying to understand someone else. Not sure if this is totally appropriate, but it does seem like something that a chatbot would be good at combing through to find examples to suggest why one thinks a certain way about a new topic. You could even ask it about your own worldview!
Non tech, but I started a sports beverage company with my brother and a neighbor. We are based in South Florida.
My brother and I grew up playing sports and remember the simplicity of home-made drinks we'd take to games that blew the likes of Gatorade out of the park. We aim to replicate the simplicity of home-made drinks with simple ingredients.
Our whole value-add is based around the fact that most sports drinks or hydration drinks contain a lot of junk. We are opposed to the bullshit catch-all that is "natural flavors" and believe in product transparency and honesty. Our products straddle the line between fresh-pressed juice and sports drinks. Our prices are definitely on the higher end, but with scale, we can lower them.
We currently are in growth mode - and currently are one of the best selling products in the top boutique gym chain in the Miami area, as well as going strong in all SoFLA Equinox locations (except for the WPB location which isn't open yet).
We do sell online but shipping is a PITA as overnight shipping costs for cold products are astronomical. When we find a cheaper solution so I can ship around the country, I'll let everyone here know :)
Based in South Florida (Miami-Dade, FtL, West Palm)? DM me and let's meet up!
I can't find the nutrition information anywhere on the site.
The first thing I look for when I see "no sugar added" on any product is the sugar content. Not being able to see that before buying is a no-go for me.
In terms of our sugar content, is 16g sugar and 17g sugar, respectively. (2 of our flavors are 17g, one is 16g).
In terms of "no sugar added", it's true, we don't add sugar. But we have natural sugars involved - our drinks are made with real fruit which obviously contains sugars. But we don't add stevia, fructose, or anything like that.
Part of hydrating effectively is adding sugar to your bloodstream as well as salts, etc.. in the right balance in addition to water / liquid.
Pretty cool, I’m sure you’re well aware but I feel like the powder packs are the future here. Makes E-commerce more feasible too. Have you looked into this? Guessing the fresh part rules it out?
Writing as someone that’s switched to liquid iv and have tried LMNT and a few others.
Yes. I get asked this frequently. I don't want to follow the same trend bandwagon that it seems everyone is on. Stick packs taste fake and often are loaded with non-essential junk (the FDA also doesn't regulate a lot of supplements).
A lot of stick packs are also leaning heavily into "natural flavors". A lot of our customers are people who go out of their way to avoid "natural flavors". If I put something in my body, I want to know what that something is, and I don't trust some catch-all term abused by corporations who put harmful chemicals in their products.
>Guessing the fresh part rules it out?
Correct. Gatorade is my competitor, not LMNT. If you're a fan of stick packs, you can replace LiquidIV/LMNT with half a teaspoon of pure sea or pink salt and a few drops of fresh squeezed lime and/or lemon juice in your water bottle. The end result will effectively be the same but you'll have more control over the flavor and saltiness. And it's cheaper.
Thanks for the response. Certainly respect your direction but I happen to think the trend will mature versus fade away. I know you're going after this certain niche, which I understand, but I don't think most people care as much about knowing exactly what is going into their bodies. I mean, sales and the average American diet proves as much. For me, the convenience of keeping a packet in my bag/desk/car/etc for weeks or months far outweighs the control over flavor and cost. Also usually prefer a tropical punch flavor over lemon/lime and that's more difficult to recreate on the fly (probably "natural flavors" lol). I don't have a workout regimen I just sometimes do work that is labor intensive and it helps me recover. It's usually an unplanned activity and the powder stuff is stable and available when I need it and really that's all I care about. I haven't even looked into the ingredients to see what it is that is actually helping me, but Liquid IV definitely is helping me recover and feel more hydrated than Gatorade ever has. Helps with cramps too, which I just assume is K but again, I haven't even looked. Just wanted to share my "customer journey" as anecdata, obviously no right/wrong path here and it's your company to push in whichever direction you want. Best of luck with it, I will give it a try if I ever see it in my area!
I’m building a daily word puzzle game with a twist!
In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword.
You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got.
I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every day!
So far I’ve gotten really positive feedback and have around 100 people signed up to get notified. It’s been a lot of fun to build!
Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once.
That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.
I'm creating Comper, an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select the repos for your team (or if you feel confident, of the entire org), you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.
My initial announcement got the top spot in "What are you working on? (February 2025)" https://news.ycombinator.com/item?id=43157056 but now I'm a lot further, there's a website https://comper.io and the company is getting incorporated within two weeks.
Last week I showed it off in the Feeling of Computing Meetup (fka Future of Coding) - the recording is here and the reactions were extremely positive https://www.youtube.com/watch?v=3-rg-FPZJtk
I'm opening the private beta soon, where I mix using the product with consultancy, to get better customer feedback. Not sure if that will work, but I don't have all the features yet for bottom-up adoption.

My read of the industry in terms of software is that it's split into 3 groups:
1. Interior visualisation (basically 3D renders) which largely target the what-if amateur market
2. Big, clunky and old software tools for professional interior designers working on huge projects, which works well but has that universal sort of mild dislike to strong disdain depending on the person
3. New players who want to replace the old clunky software
Seeing this, we decided not to try to overthrow the old all-powerful project management solution, but rather to replace a single process in the interior design workflow. And of course to do it very well.
I'm currently building Visirya, an app that helps people record their night dreams and transforms them into short videos and written journals. The bigger goal is to use this dream data to create dream cartographies, essentially maps of recurring themes, emotions, and symbols—to uncover patterns and insights across dreams over time.
So far, we've built the video generation and dream journaling features. The app is live on TestFlight, and we're preparing a major update soon that includes a new better UI, and dream questionnaire to help with pattern recognition and dream mapping.
Would love to hear thoughts, feedback, or connect with others working on similar intersections of tech and the mind! If you're interested in trying it out, you can find the TestFlight link on our website: https://visirya.com
Super cool! I'm building in the same space but for Muslims - Dreamstate: Interpret your dreams Islamically https://dreamstateai.replit.app/
I tried your app - it's quite abrupt to go straight to Access Microphone permissions. The voice recording took a long time to analyse, it timed out for me. It's a great idea but didn't work for me unfortunately.
The idea is nice, but I wonder if a generated video can have any resemblance of the actual dream. At least for me, dreams are very tied to emotion, and the visuals are kinda blurry, so i don’t know if that sort of thing can provide any satisfaction. But I know certain aesthetics can feel “dreamlike”.
I've been working on a book called "The Little Chronicles of Mathematics, Data, and the Mind of Machines", this is a 100 sections journey from counting stones to thinking silicon.
This book is more like a storybook for curious builders. I wrote it for people who love see how things connect, how math become language, how data become memory, and how machines learned to reason. If you enjoy clear ideas, and big arcs of history, this book is for you.
Thank you for showing this. I am slowly working on a book with a similar goal as yours.
Your book is very interesting and inspiring.
Your work might have gone unnoticed by most, but not by me.
Big respect for sticking to it and not giving up.
Thanks! Feel free to DM me if you'd like to collaborate, I would really love to hear more from you. People often ignore this kind of work, but at least I had the courage to share it.
I skimmed this and it looks like a remarkable work, and clearly you've put a lot of time and love into it. What inspired you? What are your next steps? Also, how do you deal with the disappointment of too few github stars? What is your success criteria?
They're all fully automatic GPS-enabled timepieces. For a couple of years I've been developing, hand-making, and selling these clocks that track the moon phase, the sun's position, etc.
My new idea is the tide clock "NautiKron." It's getting a lot of interest from US coastal buyers.
Putting the marker inside the tide curve would give it a cleaner look.
I considered it, and figured it was more legible to have the hour marker directly under the numbers. People looking at the NautiKron from across the room or who have low vision might like it better this way.
Good idea to revisit -- I'm always tweaking the designs and responding to owner feedback.
Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!
I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)
As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.
Very much a hobby, but I'm working on a Pinterest alternative built on ATProto called Scrapboard[1]
The Bluesky ecosystem is a really great platform to build social media on and with Pinterest being overtaken by AI content I figured I'd give it a shot. There is definitely not as much content there, but it is of much higher quality and the culture of providing alt text on images really makes search work rather well.
Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1].
Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my mom got for me for Christmas when I was a kid.
I hope to sell them and then probably never recoup my investment.
I’m building https://www.kidcarekit.com, a Rails SaaS for family-run daycare centers that still juggle spreadsheets and phone calls. It wraps waitlist management, enrollments, and Stripe billing into a single dashboard with Tailwind + Hotwire on the front, Devise for auth, and Azure Blob for logos. Solid Queue handles scheduled jobs like weekly tuition and late fee automation so owners get predictable cash flow without hand-cranking invoices, while MailerSend keeps parents in the loop.
Right now I’m polishing the onboarding flow so new centers can import families, configure their billing cadence, and connect Stripe in under ten minutes. Next up is richer analytics (occupancy tracking and revenue health) and rolling out a guided setup for late fee policies. If you’re running childcare ops or know someone who is, I’d love feedback on the workflow pain points you still feel daily.
I'm trying to make an RF lightning detector small enough to trivially add to my motorbike.
I live in Viet Nam, and driving through bad storms this time of year is pretty miserable, and they happen fast and are local enough that weather prediction is not terribly useful.
There are a lot of problems with EMI. Lots of ungrounded brushed motors everywhere that make the RF bits hard. If I succeed, I'll publish the PCB designs.
I've also got some educational products in production right now, about Vietnamese history. I'd share a link, but my website probably can't handle the traffic right now.
Building Evidentia – platform for scientific knowledge that never gets published
Science's most valuable output never gets published. Negative results, failed replications, protocol details etc. all vanish into the file drawer. This means that the public body of knowledge is slow and also often wrong.
The cost: 70% of researchers can't reproduce published findings. Only 6 of 53 landmark cancer studies replicated. Industry wastes $28B annually re-validating work that doesn't hold up.
We're building a platform to capture what gets lost. Scientists share the details papers omit: failed antibodies, critical protocol tweaks, replication attempts. AI + a graph DB structures it into queryable data. Contributors get DOIs so it counts as real academic credit.
Been testing with beta users for 2 weeks. Opening up waitlist now: https://evidentia.bio/
Key challenge: will scientists share without traditional publication incentives? Early signal says yes (especially younger researchers), but needs to scale.
Feedback welcome, especially on keeping it alive (avoiding the "data graveyard" problem) and monetization.
I love these threads, and always learn or pick up something new.
From my side, I've been working on a multi-lingual first words book for a baby. None of the published books have our mix of languages (which is fair enough, I don't think there is much of a market for it!) and so I decided to create our own. It's just images and then the word translated into three different languages alongside it (like a typical first words book). I used Google's AI for the images, and it has done a surprisingly good job of creating baby friendly images, with enough detail to spark interest.
The other tangential benefit is that I found it awkward to speak in my mother tongue, but having this book helps break that by having me speak in that language and then leads to it feeling much more natural in other contexts with babies.
This is not very technical project (though if I had the time it could easily become a fun project where people select their unique mix of languages and the book gets produced).
If anybody is in a similar boat and wants to produce their own version for their mix of languages then please let me know and message here - I will happily share the Canva file with you (you'll just need to write in the words yourself). (This idea of sharing is inspired very directly by Derek Sivers 'Sharing' idea [0])
I started a company to grow unlimited eggs from stem cells, based on the work from my recent PhD. This will solve nearly all female infertility and help prevent genetic disease.
Are you making a joke, or is there some use for that? (I would think of all species on earth, chickens are the easiest to get eggs for once you exclude the insects, but lack of domain knowledge means I could easily be missing something)
Not OP but I think there are a lot of people (maybe mostly vegans) who would be interested. I have no thought on whether it would be financially viable.
I'd be interested just because I'd rather use non-animal alternatives if available.
I hope lab-made milk becomes a viable thing even though I'm not vegan or vegetarian. Lab-made eggs would be good too.
Not the person you asked, but there is a lot of research in this for meat so it would be interesting for eggs as well, as replacing them when you are vegan is not that easy.
Currently it mainly focuses on libGDX which is my most favorite framework. I prefer code-centric approach because that's how game development should be in my opinion.
Most of the tutorials are just pure coding with algorithms explanations. My goal is to build one of the most resourceful website for libGDX because it's quite underserved at the moment.
In the future I may expand to other code-centric frameworks and more general game development topics, let's see how it go.
First time hearing about libGDX. Do you have any resources on why it's your favorite framework? It might be useful for your website as well. To sort of "sell" the framework to game developers who have not used it before.
libGDX is not in the same spotlight as Godot or Unity but still popular within Java devs circle.
I'm not aware of any resources explaining the "why libGDX" but here are some differences, speaking from my own experiences:
- Code oriented development, no authoring tool, no drag and drop, just you and the API, which might attracts traditional devs who prefer a pure coding approach.
- Very thin abstraction over the platform graphics layer, it just adds a few more drawing APIs over the underlying graphics API (OpenGL and WebGL). You’re free to build your own abstractions on top of the core APIs.
- Java, while might be verbose, is very stable, easy to learn and has huge ecosystem. Or you can just use Kotlin.
- Once you learn the ins and outs of the framework, it actually has a greater sense of freedom compared to Unity, Godot, Unreal, etc because those engines always force you to do things in their own opinionated ways.
I'm pursuing my vision of "music-i18n": Open source music software that works for microtonal music and worldwide musical cultures.
It's not a from-scratch effort, quite the contrary: I'm trying to tie in existing music standards (MIDI, MusicXML, SMuFL, MEI, etc.) and ensure that FOSS systems (MuseScore, Verovio, smaller components) implement enough of those standards to support music-i18n.
Sometimes, this also includes extending the standards themselves when they are not fully capable of representing some non-mainstream musical aspect. For example, MusicXML lacks the ability of representing multiple accidentals per note (whereas MEI does), which is a must for microtonality.
I started down this path around 2018, as a music player who got interested in arranging Arabic songs in a "Real Book" style. It opened a giant rabbit hole that I'm still far from having fully explored.
Now and then, I collaborate with other devs who are interested in adjacent topics. I would love to hear from some of you here!
I pride myself on being pretty well organized with my digital life, especially files and folders. I’ve been using Hazel (God Knows, since it's beta). Recently, I realized it has become a muscle memory for me to name/rename files, and drop them where they belong while I'm working on or as it happens. This works for me now because I have a weekly routine of digital chores that picks up any slack and missing things that I missed during my days. Compound this with the fact that I have reduced a lot of clutter, minimized things that I’m involved in. That worked. I did away with Hazel since the beginning of 2025 and I didn’t missed it.
However, I’ve been sheepishly and shamefully looking at either an AI-assisted solution to even do away with the last mile cleanups and organization that I do.
Your text above is good enough marketing for me, and your website’s content sealed it. Didn’t even look further. I’m your customer now. And, personally, have always loved supporting other founders/builders building interesting tools and utilities.
Edit: I just realized this is not compatible with Intel Macs which I wanted to use on too. I didn’t read everything on the website, did I?
Suggestion: Please send me an email after successful purchase, so I have a record.
Thanks so much for your thoughtful comment and support, Brajeshwar — it really means a lot.
You’re right, Fallinorg currently only supports Apple Silicon Macs. The main reason is that the M-series chips have neural engines and very high memory bandwidth, which makes the AI models run fast and efficiently. On Intel Macs the performance just isn’t the same, but I do want to explore ways to bring a great experience there too. If you’d prefer a refund in the meantime, just let me know and I’ll send it right away — no worries at all.
Also, thank you for pointing out the email confirmation — I’ll definitely add that.
I noticed you mentioned using Hazel for years and building up muscle memory with rules. Right now, Fallinorg is built around content-based AI classification rather than rules. But rules can give a lot of precision and flexibility. Could you share what kind of rules or workflows you relied on most with Hazel? That would help me understand how people like you used it, and how Fallinorg might evolve to cover those use cases better.
Again, really appreciate your support and feedback.
Some of the key uses that I remember with Hazel were;
- Of course, cleaning the Trash, Downloads, and the “tmp” folder to either delete or mark as old for me to attend to during my digital chore sessions.
- Syncing a backup copy of all Work-Related Google Workspace, which is pre-converted to Open File Formats (I use InSync for this.)[1]
- Screenshots older than a set day to be archived into the Pictures Backup folder. They are yearly for now. So, I have almost all screenshots I ever took, since 2022, in their yearly folder (YYYY). Each year is less than 1GB, so I’m fine with the storage.
This might be what I've been looking for. On the first of every month I have Hazel put everything in ~/Downloads/yyyy-mm (previous month), with the intent to move each file to the correct project/area folder in my actual file structure. But I'm about 1.5 years behind on that...
Have you looked at competitors? If so, what are they? I haven't found anything that does this as elegantly as Fallinorg.
Thanks for sharing, jonpurdy — I know how fast that backlog can build up!
Most tools I’ve seen (like Sparkle) sort by file name, but that only works if names are clear. Fallinorg looks inside the file itself, so it understands what the content is about before sorting. I haven’t found another Mac app doing that.
Curious — if Fallinorg could automatically handle your ~/Downloads/yyyy-mm folders each month, would that take care of the backlog for you?
Thanks Jon, Custom categories are available starting with version 3.0 beta. To add one, open Fallinorg Settings → Add New Category. Then enter a name, description with keywords or sample sentences, and make sure the destination folder is set correctly.
Could you please check in the About section which version of the app you’re running?
I'm working on a new unconventional form of computing called "temporal computing" - as both a PhD and as a fledgling business. The idea is to use delays in time (It's called interval modulation) as the data. I have a video explainer on YouTube https://youtu.be/rXbzJxThgig?si=FYMleAgZ0GMNEqk9. It's a long road building your own computational model and I'm currently looking at Turing completeness, and models of multiplication.
Well, that's certainly an interesting way to save energy in a logic circuit. The problem I see is that you're going to be able to have to save the value in an analog form at some point to do anything other that single bit math.
Perhaps looking at using each transition in a circuit as a bit, instead of level, could be useful as a power saving strategy that could be compatible with existing VLSI fabrication?
As someone who's curious (I see lots of room for improvement in terminals!), I can't tell what this does from the website, other than the ability to load and view 3d models.
Vibescape: an immersive meditation app. This one is currently featured at the top of the App Store, yay! Launched as a day one app on Vision Pro, new update has what I think is the best immersive environment I've made yet that comes alive with music: https://apps.apple.com/us/app/vibescape/id6476827678
I have made a Bürgeramt appointment finder. It was down for a few weeks after the city of Berlin changed its anti-bot measures. I just released an updated version that works again: https://allaboutberlin.com/tools/appointment-finder
My citizenship wait times page (https://allaboutberlin.com/guides/citizenship-wait-times) has also gotten enough feedback to be useful since its release last month. I'd like to make it more useful with better visualisations.
Now I'm working on another iteration of my health insurance calculator (https://allaboutberlin.com/tools/health-insurance-calculator). It's kind of a big deal both because it's a huge financial decision for recent immigrants, and because it funds a big chunk of all the free stuff I'm putting out. This is especially important with ChatGPT and AI summaries halving my traffic. This iteration will recommend health insurance combinations that work for a visa application and for a long-term stay in Germany. It will provide far better explanations.
At the same time, I'm testing a new insurance broker with far shorter response times, so people can directly ask an expert to help them choose. They're reachable via Whatsapp, and that made a huge difference in how people get advice. It worked so well that I want to do the same for other topics. I'm already talking with an immigration lawyer who's interested.
I'm working on Macscope (https://macscope.app), a better Cmd+Tab for macOS. I built it because macOS window management feels slow compared to the keyboard-driven speed of a terminal or code editor.
It augments your existing muscle memory: a quick tap of a shortcut switches apps like normal, but holding it opens a powerful interface with features like:
Unified Search: Instantly find any window, app, or browser tab.
Scopes: Save and restore entire window layouts for different projects (perfect for after you unplug a monitor).
Placement Modes: Snap windows to screen halves as you switch to them.
The goal is to make the OS feel as fast as my other tools. I'm always looking for feedback on how to make window management less frustrating!
Working on a personal recruiter / talent agent for my smartest dev/product/design friends (and theirs) https://www.hedgy.works
Key problems we're solving:
- Everyone wants to be doing meaningful, fun work that feels like their "life's work". Few feel like they are.
- In recruiting, the AI spam problem is real and only getting worse, essentially killing the cold application pipeline. You need a referral.
- Optimizing your career feels like annoying politicking for a lot of the most talented folks who just want to focus on building cool stuff. But, as an employee, if you don't test the market (e.g. take a recruiter conversation) from time to time, your comp can really stagnate.
How are you planning to generate revenue? My concern will fully free services is that they often don't exist after 3-4 years. Then I have to find another invoice generator. Sticking to WaveApps for now, but this is looking great actually and I'd consider using it.
It’s completely open-source, so it’s easy to fork and self-host if you want to avoid lock-in. I originally built it for myself and don’t have plans to monetize it. Even if I do in the future, the current version will always stay free and without sign-up. Any monetization would come as a separate pro version with extra features, not by removing what’s already available =)
I left my job to work on my side project (MCP-B: https://news.ycombinator.com/item?id=44515403) full time. I set out with the goal of making the ability to vibecode a webMCP server for your website and inject it via userscript.
While building that, I basically wrote a modern version of Tampermonkey with its own marketplace built in. So you can vibe code any userscript and publish it to the marketplace all within the extension.
The automation stuff is still the core value-prop, but this is a fun bonus feature while I work on solidifying the automation features.
I'm writing a HN post for it. Excited to show everyone in a couple weeks here.
I'm finally organising 20 years of voice notes. Some were quite outdated - I probably no longer need the mozzarella cheese I reminded myself to buy in early 2008.
To organize them, I'm writing a Python Qt application with Claude Code. It started off as vibe coding, but I'm now developing it using processes very similar to those I would use when managing software teams. I've picked up a lot of good tips about that here on HN. I've got Whisper, and fallback online services, transcribing the audio and summarizing it and adding tags. After much UI experimentation, I've landed on something that looks not unlike an email client, with tags in the left pane, a center pane which lists transcriptions and notes about each audio file, and a right pane with more detailed information about the selected audio file.
Next step is to serve it all as a model context protocol server - I need to pick an agent.
I've been building https://resolver.one - a DNS server that returns GeoIP data as TXT records. Query an IP directly as the hostname (e.g. dig TXT 8.8.8.8.rslvr.one) and get back country, ASN, etc.
Always been fascinated by repurposing established protocols for unintended uses - DNS is everywhere, passes through firewalls, and has built-in caching. Seemed like a fun way to deliver location data without HTTP APIs.
Super niche, definitely a bit odd, but that's the appeal.
I work for IPinfo, focusing on data adoption and supporting the wider use of our free services.
The dataset the user is accessing (IPinfo Lite) is licensed under CC-BY-SA 4.0 and does not come with an End User License Agreement (EULA).
Most free IP geolocation databases in the market do include restrictive EULAs. These usually require each individual user to register, obtain their own copy of the database, and limit usage to themselves only. In many cases, sharing the data or keys outside of the original intended scope is considered a violation of license agreement. Because of these restrictions, some providers also offer paid redistribution licenses, which can be expensive and typically targeted at enterprises.
Our approach is different. By licensing IPinfo Lite under CC-BY-SA 4.0 WITHOUT an EULA, we allow anyone to share or redistribute the data freely, as long as proper attribution is given. The goal is twofold:
- Make it easier for projects to use the data without legal barriers.
- Ensure that any questions or issues about the data are directed to us rather than to project maintainers.
Some large open-source projects, major global enterprises, and governement institutes are already using IPinfo Lite right now.
Data source is IPinfo Lite MMDB file, which seems to be offered freely without restrictions. I'd love to offer comprehensive GeoIP attributes but I'm afraid to even ask how much the DB download of that costs... I'm working on supporting new data sets now like security CVEs, shodan integration, etc.
Continuing to do a lot of historical review of early AI stuff. Just finished the Semantic Information Processing[1] book edited by Marvin Minsky, and now I'm reading Volume 1 of the Parallel Distributed Processing[2 book by Rumelhart and McClelland. After that, I have Principles of Semantic Networks[3] by John F. Sowa queued up.
Along with all of that, still working on a lot of stuff using Jason[4] / AgentSpeak[5]. I created a fork[6] of Jason that is meant to be easier to integrate with Spring Boot, and to take more of a "run headless on a server" approach, which meant taking out references to a Swing based in-process logging/management tool. In place of that, I'm implementing a JMX based management interface, and recently I've started to work on replacing the old Swing app with a JavaFX app that can connect using JMX Remoting.
It's funny you say that. I already do run a weekly "book club" group, but it's at work at my $dayjob employer. And, for various reasons, we've drifted away from the book focus and turned into a more presentation/discussion oriented group. But I still love to read physical books, and wouldn't be opposed to trying to come up with something to structure some discussion around some of these "outside of work" readings that I do.
If you want, drop me and email (prhodes@fogbeam.com) and maybe we can set something up.
Blobcache is content addressed storage, available over the network.
Blobcache allow nodes to securely produce and consume storage.
Configuration in similar to SSH, drop a public key in the configuration, and you're done.
Blobcache is a universal backend for E2E encrypted applications.
Got is like Git, if you fixed all the problems with storing large files and directories in Git.
There's no "large files provider" to configure separately.
All the data for a commit goes to the same place.
Got also encrypts all the data you put in it, E2E.
If you've run into problems putting your whole home directory in Git, you might have more luck with Got.
Both projects are GPL licensed, FOSS. Contributions welcome.
Trying to reboot an early-middle-aged brain that has succumbed to a terrifying, long-term brain fog that has almost crippled me by ruining my concentration span.
Personal projects, developing a habit of contributing my time to a large open source project (having only ever run my own very small ones), teaching newer users how to use that open source package by answering questions and making little example videos, beginning to repackage my notes on things into blog-publishable writing.
Really anything that will help me use brief moments of concentration span to rebuild my confidence in my own ability. It is like a snail ride through treacle but this is the first month-long span in nearly two years where I don't feel like I am falling apart.
I've been working on a map that shows which neighborhoods in a city are nice/not nice with a short description.
Whenever I visit a new city, just looking at Google Maps is pretty meaningless - it's just a bunch of gray land and streets. I end up looking up Reddit posts for where to go, searching for crime maps, trying to find annotated maps, etc. to get a better idea of where to visit in a city (or even live, like when I had moved to Austin). AI generated scoring and descriptions, while imperfect, have already helped me when visiting SF recently. Early stage, so please help with submitting corrections, if you'd like!
I just checked a few cities I have been to and this seams surprisingly accurate. May I ask how you are collecting this data. Is it through Google reviews or how do you collect this data?
Very cool! I really like the idea, the way I'd develop this further is by having live crimes reporting on it so that you know which streets to avoid , similar to what waze does where people report items
I like the idea! In my opinion (looking at SF) it’s still too low resolution. SF in particular can vary greatly in safety, walkability, etc. even a few blocks over within a neighborhood.
I'm working on a partition-oriented declarative data build system. The inspiration comes from working with systems like Airflow and AWS step functions, where data orchestration is described explicitly, and the dependency relationships between input and produced data partitions is complex. Put simply, writing orchestration code for this case sucks - the goal of the project is to enable whole data platforms to be made up of jobs that declare their input and output partition deps, so that they can be automatically fulfilled, enabling kubernetes-like continuous reconciliation of desired partitions.
This means, instead of the answer to "how do we produce this output data" being "trigger and pray everything upstream is still working", we can answer with "the system was asked to produce this output data partition and its dependencies were automatically built for it". My hope is that this allows the interface with the system to instead be continuously telling it what partitions we want to exist, and letting it figure out the rest, instead of the byzantine DAGs that get built in airflow/etc.
This comes out of a big feeling that even more recent orchestrators like Prefect, Dagster, etc are still solving the wrong problem, and not internalizing the right complexity.
Very much agree that to this is the direction data orchestration platforms should go towards - the basic DAG creation can be straightforward, depending on how you do the authoring - (parsing SQL is always the wrong answer, but is tempting) - but backfills, code updates, etc are when it starts to get spicy.
I think this is where it gets interesting. With partition dependency propagation, backfills are just “hey this range of partitions should exist”. Or, your “wants” partitions are probably still active, and you can just taint the existing partitions. This invalidates the existing partitions, so the wants trigger builds again, and existing consumers don’t see the tainted partitions as live. I think things actually get a lot simpler when you stop trying to reason about those data relationships manually!
Testing jig for a traction control system for a locomotive. Microcontroller connected to a DDS waveform generator simulates the sensor that picks wheel speed, various ADCs and DACs read in analog voltages that are compared to determine loss of traction. 1980s analog computing at its finest. If I had a choice I would be doing anything else ;)
Continuing to build https://crucialexams.com/, a platform that helps people prepare for IT certifications like CompTIA, AWS, and Microsoft/Azure. It offers realistic practice tests and study tools. I also have partnered with educators and universities who now offer it to their students and get dashboards to review student progress and identify where they are struggling.
is a unified interface across OpenAI, Anthropic, Google, and Ollama - same code works with all providers.
Use aliases instead of hardcoding model IDs. Your code references "summarizer", and a version-controlled lockfile maps it to the actual model. Switch providers by changing the lockfile, not your code.
Also handles streaming, tool calling, and structured output consistently across providers. Plus a human-curated registry (https://llmring.github.io/registry/) that I (try to) keep updated with current model capabilities and pricing - helpful when choosing models.
An MCP server and client are included, as well as the ability to help you define your aliases/models with an interactive chat.
It's a thin wrapper on top of the downstream providers, so you are talking directly to them. And it also comes with a postgres-backed open source server to store logs, costs, etc.
MIT licensed. I am using it in several projects, but it's probably not ready to be presented in polite society yet.
It's been a while since I've used CloudWatch myself. How would you expect this? IE would you lean more towards having a lambda/firehose that forwards events to to the API (which is [public](https://tailstream.io/docs/api) by the way!) or would you expect some kind of agent / connector to run that automatically pulls the logs from CloudWatch?
I'm working on an audiobook service (currently for myself) that will fill in major missing features for platforms like Audible.
- Ignore AI voiced books
- Show me unread books in series that I have in my library
- Experimenting with better search. I have experience with building semantic search systems and have been highly disappointed with Audible's extremely sub-par search capabilities. I want results that are actually based on books, authors, and narrators that I have already purchased, read, or listened to.
- Get automatic notifications when new books from authors and narrators that I subscribe to become available.
There's at least a few more gripes I want to address, but these are the high priority ones that come to mind right now.
My biggest issue these days, is that after spending 1000 hours messing around in eleven labs, almost all female american audiobook narrators sound AI generated to me. I feel like as a demographic they must have sold a lot of voice recordings to the platform for analysis. I have DNR'ed a few audiobooks recently due to this.
It is a desktop app built with Electron and React. I built to help newlywed couples to quickly sort thousands of wedding photos with a Tinder style swipe UI. It is offline first, fully private, and offers one click export of your selected pictures.
I started building it earlier this year after going through my own wedding photo experience and realizing how overwhelming it can be. I saw my wife dragging and dropping photos from one folder to other and thought there has to be a better way for non-photographer folks.
Right now, I have a working prototype, a landing page live, and I am testing distribution and feedback from early users.
I'm still working on DocSpring (which I launched on HN in 2017 as "FormAPI"). It's a tool where you can drag-and-drop fields onto a PDF to create a template, then post data to our API to generate PDFs. We also support e-signatures and hostable forms.
It's still going well, and I've been making a ton of progress lately by using AI agents. I'm very excited to launch my new homepage and pricing soon, plus some other really cool side projects that I've built.
I just finished some new features today and launched v0.5.0. The VS Code extension and MCP server are both really handy. I've been using them for quite a few different renames lately. This is one I did today: https://docspring.github.io/renamify/case-studies/deploy-req...
I'm putting a bunch of security tools / data feeds together as a service. The goal is to help teams and individuals run scans/analysis/security project management for "freemium" (certain number of scans/projects for free each month, haven't locked in on how it'll pan out fully $$ wise).
I want to help lower the technical hurdles to running and maintaining security tools for teams and individuals. There are a ton of great open source tools out there, most people either don't know or don't have the time to do a technical deep dive into each. So I'm adding utilities and tools by the day to the platform.
Likewise, there's a built in expert platform for you to get help on your security problems built into the system. (Currently an expert team consisting of [me]). Longer term, I'm working on some AI plugins to help alert on CVEs custom to you, generate automated scans, and some other fun stuff.
I am working on FastFileLink (https://fastfilelink.com/), yet another file-sharing CLI/app that uses WebRTC for P2P transfer but exposes HTTPS links, making it compatible with browsers and tools like curl/wget.
It's ~90% production-ready. We use it internally to move files between containers and hosts (especially when volumes aren't mounted), and for WFH employees to exchange large files without a relay server.
For huge files, there's resumable upload to our infra-backed server — fast global downloads included.
The CLI will also support receiving files via WebRTC, but that feature hasn't been released yet. It is open source (https://github.com/nuwainfo/ffl), but the README hasn't been updated yet and the code is not synced with the latest version (working on these).
Another production-used tool I'm working on is
MailTrigger (https://www.mailtrigger.net/) — a programmable SMTP server that turns any email into a message on LINE, Slack, Teams, Telegram, SMS, or basically anything.
If your app can send email, it can trigger multi-channel notifications with zero extra code.
Think of it as “SMTP to Anything,” or an email-native IFTTT/Zapier.
It supports JS and WASM for preprocessing, routing, and automation — you can write custom logic, auto-reply with LLM-generated messages, or forward alerts intelligently.
We use it for price drop alerts, server health monitoring, and integrations with Jenkins/Sentry to push incidents to our DevOps Telegram channel.
Also experimenting with LLM-assisted rule creation: you can define notification logic in natural language instead of writing code — for example, auto-reply with an LLM-generated joke or handle customer support queries dynamically.
Docs are more complete than the website (which is still evolving), and the pricing page is currently a placeholder.
Already running in production for us and a few early adopters.
Working on an automated OSINT tool. OSINT is a tough nut to crack because there is so much one can do and the web is literally infinite. So, this tool can automate browsers, it can call functions in a ReAct loop and make inferences on that. It essentially a combination of an investigator + a tool.
I'm working on graph insight, a semantic graph tool for exploring research papers.
It extracts keyphrases, builds a 3D graph, and lets you navigate from documents > topics > clusters.
So far: ~28k papers processed, 100k+ topics mapped.
Use case: faster literature review, spotting hidden links, and seeing research areas as a connected landscape instead of isolated PDFs. I think this tool applicable for news/media streams too.
I'm rebuilding OnlineOrNot's frontend to be powered by the public REST API. Doing this both as a means of dogfooding, and adding features to the REST API, that I easily dumped into the private GraphQL API without thinking too hard.
Basically I've realised GraphQL has taken me as far as it can, and I should've gone with REST to start with. That, and after I finish the first milestone (uptime checks + cron job monitors), I'll be able to start building a proper terraform provider, and audit logs.
I'm still working on Danger World (https://danger.world), my casual 2D narrative adventure with turn-based RPG elements. Built in Flame, on top of Flutter for iOS, Android, Windows and MacOS.
We're getting close! It's just a matter of polishing and polishing and polishing, but I'm really excited about how close we are to launch.
Work continues for me on Rad[0]. It's a programming language designed specifically for CLI scripts. I was sick of writing Bash scripts and thought we could do much, much better, so that's the goal with this project.
Been working on it for a bit over a year now, and I'm using it every day! Still have many big features in mind, such as commands, I suspect I'm still only at the beginning at this journey!
Working on a dutch voting compass that uses real world motion votings as a way to determine which party fits you best. The Netherlands got an open API for this since last year, so it felt appropriate to start using it.
Top man! Thanks, I went trough the votings to see if the party I was thinking of matched actual voting behaviour in the 2e Kamer. It kinda did, but I was suprised another party matched a bit more.
Since that second party also comes forward in other voting compasses I might be more inclined now to vote them instead.
Super goed idee! Ik zie dat de titels/bronlink soms niet overeenkomen met het kernverzoek en beschrijving eronder, daar gaat iets niet goed. Misschien ligt dat aan de open data.
I'm working on Pruno (https://pruno.dev/), it's similar to Dependabot/Renovate bot but it removes dependencies instead.
My team suffers from dependency creep. As soon as your system grows, the number of dependencies skyrockets. In Python/Javascript projects it's especially hard to determine which dependencies are not used anymore.
Pruno saves time for your team by automating this work. It's still WIP, but I'd like to get feedback. How are you dealing with your dependencies?
I've been contributing to a project called Folk computer[1]. It's focused on creating a physical medium for computing (think printing out a program, which is then tracked by the computer. There's some really cool spatial interaction that happens). Folk v2 is currently in development, so I've been digging into the guts of the datalog-like engine. It's been a lot of fun to pick up C and see it applied to a project I can directly interact with!
I recently released JazzEar, an iOS app for ear training. Specifically focuses on improving recognition of chord progressions you would hear in jazz standards.
Now I'm working on a smaller app for jazz musicians to manage their tune list and act as a tool to help practice and review tunes. I wanted this app to tell me what tunes on my list I haven't played in a while (and might forget), or try different keys or exercises on the tune and track what I found difficult.
Trying to re-legalize "neighborhood commercial" by right in the city I live in. Things like corner stores or small barber shops or coffee shops or converted restaurants. ACUs or Accessory Commercial Units, home conversions... different ways of doing it.
Great. I assume you live in the US ? Your urban planning law are atrocious. In countries like thailand for instance it's very common to have a shop in the house. Things go nicely and it's more lively. Good luck, that a good project at the root of so many issues
If you have a shop in a house in Thailand and a crazy person decides he likes the shop and stays in front of it all day yelling, in Thailand, the people in the house call the police, who make the crazy person leave. In the US, every person, crazy or not, has Freedoms and Rights, and the police won't do anything to help the people in the house because it would be wrong according the the US way of thinking to curtail the Rights and Freedoms of the crazy person (who is yelling all day near the shop, which is very near the house).
Consequently, owners of houses in the US try to make it as boring as possible and as useless as possible for any crazy person, homeless person or group of teenagers to hang around near the house. One way they do this is to make sure the house is surrounded only by other houses, trees, parking spaces and roads (and there is not anything as useful or interesting as a shop in easy walking distance).
This is a bit of an exaggeration, but it is directionally accurate.
No, it's mostly just car-brain where people think that cities should be designed around cars cars and cars, and then if there's room left over, maybe some shops and homes.
So they worry about a neighborhood shop taking up the precious, precious parking spots or causing 'traffic!' even if in reality it reduces it because people have something close by their home they could even walk or bike to.
So the root problem is not the American commitment to rights and freedoms (especially for the disadvantaged) that Americans discuss constantly -- often in heated, emotional or abstract terms and sometimes in frankly ideological terms. According to you the root problem is an irrational and destructive commitment to automobiles, which (at least after the 1960s) Americans talk about much less than they talk about rights and freedoms -- and
when they talk about them, they talk mostly in pragmatic terms, e.g., miles per gallon, turning radius, maintenance costs and space for car seats for children.
I live in a city of 100K people, where there really aren't that many visible people with mental health issues or drug problems. I also go to a lot of city council meetings and hearings and observe local social media.
There's some writing up at https://bendyimby.com/ but it's not really 'documenting my experiences'. What would you like to see/know? Feel free to write me an email, I'm more than happy to chat about it!
Working with local government is different everywhere and there are probably different groups that are more or less effective in different places. As above, happy to give you some basics if you want to write.
I'm building a tool shed completely from scratch. Actually doing woodwork (ok ok it was also an excuse to get a nice nail gun) and seeing something tangible at the end of your efforts is surprisingly nice if your day job is entirely virtual.
My favorite pattern I've found is to write encode implementations manually, and then AI pretty easily is able to follow that logic and translate it into a decode function.
Most of our jobs consist of working with tools. Yet it’s very hard to get insights into which tools are required most, are growing in your area, etc. So I decided to keep track of tools and technologies mentioned in the data space by keeping track of job openings for the last two years. Now I’ve opened up that data set. Here’s an analysis for jobs per data warehouse: https://selectfrom.work/insights/data_warehouses
Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer
Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things.
Next addition will be to add health inspection data from countries that have that in open datasets or APIs, so if anyone know of that I'd be appreciative of hints (know of UK, Norway and might have found for France).
The number and the fire icons are popularity ratings, and shouldn't be expected to say a lot about quality. That value is derived from a set of automated signals that can be considered proxies for popularity. For most markets we typically see a couple of stand outs, and "the rest". One major flaw is also that we don't know venue capacity, so this probably does bias towards bigger venues
For NYC specifically it could be many factors playing in.. Perhaps we don't really have the right venues listed? Maybe the city favors small neighborhood bars over bigger destinations? etc..
I just recently added the number behind the icons, but one of my concerns was that it would then be interpreted as a review rating. Might re-consider the UX of this now. Thanks for feedback!
That sucks. I see the value in that, and I can add a tag for it. Imagine maintaining a consistent status for that automatically would be hard though. So the meaning of such a tag would likely become "They had at least one gluten free option at one time".
For venues publishing their drafts, cans or bottles publicly it could be possible to create some confidence interval if we scrape the data and keep history of it.
Thanks for checking it out and leaving a suggestion for improvement!
They are becoming more common, as it's very simple to make them GF- you can simply add an enzyme that eats up the gluten. Bristol Beer Factory's whole range is GF and very tasty (my local brewery).
I'm trying to incentivize people to build IRL communities instead of AI-related apps because the demand for human interaction FAR outweighs the supply. My platform (https://onthe.town), is basically Shopify for social experience clubs. Anyone can start a club and create events based around bringing random people together IRL based on shared interests. You get your own website and infra that handles signups, payments, and matching.
It's largely based on platform-izing the extremely popular Timeleft app that simply matches 6 random people for dinner. With onthe.town, anyone can create a Timeleft-like app around any concept they're interested in. Some clubs people have created include a golf club (get matched with 3 other people to play golf with), a vinyl record sharing club, a lunch club for biotech networking, and a club to meet other parents for dinner.
There was a startup in my region who got popular with the simple idea of having a website/service that manages simple events, like talks, presentations etc.
I think it started with mostly students using it because there used to be a lot of university-related events like these, and eventually they’ve become the standard platform for that, at least in the State. It was all pretty simple, it managed payment etc. and you’d get a QR code by email or in the app that could be scanned in the entrance.
Really appreciate the feedback. The idea right now is that you set up a club and attendees pay a small amount for each event, and then we take a small (~10%) fee for selecting the venues, doing the matching, and handling payments for you.
But I do love your idea and it's something I'm pursuing. We are matching people to meet at venues (restaurants, golf courses, etc) and it makes sense for venues to pay to be selected. That money would go to organizers and the events could be free. It's just a harder B2B problem to convince companies to sponsor communities.
Ultimately, clubs will have the flexibility to be run in multiple ways - from free, to business-sponsored or attendee-funded, to even onthetown-sponsored as you suggest.
I’m building a text editor inspired by ed, but instead of editing files on disk, it edits live network flows. In this model, files don’t exist as static objects—they exist in motion.
Creating a file generates a self-sustaining pattern of packets circulating through the network, and editing it changes the flow itself. Multiple users can edit the same file simultaneously, because the file isn’t tied to any machine—it’s in the network.
The interface is familiar if you’ve used ed, with commands like append, delete, and substitute, but behind the scenes it’s all live traffic. You can even discover existing flows and jump into them in real time.
It’s a Linux proof-of-concept using raw sockets, and the goal is to explore what files could be if we thought of them as living, circulating processes rather than static storage.
I'm building a manually curated catalog of games made by the HN community.
Currently the collection has data up to the end of 2022. The plan, of course, is to gather all data up to today and then keep updating the collection.
I first tried to expose the VDBE to public usage, so it could be easier to right hand-made bytecodes, but it would require an effort that I'm not quite have to a side project. So instead I'm extending SQLite's parser to accept things like `let <var> = <expr>`, and functions. Alongside, I'm doing a "standard library" so you could build web servers and stuff.
The thing I'm struggling with is managing execution state. I have the idea of doing transactional functions using function coloring (e.g async functions), so each function call opens a new savepoint, and the user could rollback a particular function call in case it got wrong. I put the deadline to be 31 October, if I manage to get this on time I'll post here on HN :)
It started as a way to learn RTOS internals, and over time it has grown into something with lots of nice features.
I’m even using it in a dirtbike anti-theft tracker I am building.
Also, this month I did a weekend challenge to build an embedded software parameter DSL and compiler.
Its goal is to let firmware developers define configuration values, thresholds, constants, and other application-level parameters in a structured,
human-readable format, and compile them into binary data that the firmware can directly use.
Really cool, but please consider adding support for using the arrow keys and/or changing the keybindings. Right now it's unplayable unless you're using a QWERTY layout.
Impressive! Feels really responsive. I feel the controls are a little unusual though: WASD corresponds to actual map orientation rather than to where the character is facing. I find it confusing when playing together with a mouse, where I would expect I can hold W to move forward while using the mouse to control the character's orientation and direction.
The initial implementation actually used that approach - but I got some complaints from people saying it felt weird and I changed it. That was a long time ago during prototyping though - might change it back and see how it feels now (or just add an option). Thanks for the feedback.
I made my pops a walnut multi-guitar stand a couple months ago and I’d like to get some nice pics done and make one of those eCommerce web site things to sell them. Here's a bad pic https://bradlyfeeley.com/onokura.jpg
I'm working on Listening Facts[0], a music habits visualization tool based on your top tracks. Inspired by Receiptify and every day nutrition facts labels[1].
It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integration.
I posted about it[3] on Last FM's subreddit and I was pleasantly surprised to see that a lot of people shared their labels on the comments and seemed to like it.
I'm currently working on language detection, I think it'd be cool to get a language breakdown of the songs you listen to and for that to be part of the displayed items within the label. Something along the lines of EN- 80%, ES- 15%, FR - 5%
I've also tried getting Adsense on the website but I keep getting denied on "Low Content Value" grounds. I tried some alternatives but the quality of their ads was ridiculous (stuff like "your device has a virus, click here to clean it up")
It's a digital comic book store. Letterboxd with a buy button. It's really fun. We've got a lot of great publishers signed, and a great team. It's such a thrill to work in a space where people work their ass off to create art, in spite of the fact that the rewards are minimal. Our job, we feel, is to make them more money to make more art.
A two-man team, we're enabling PHP developers to get into mobile app development as easily as possible - no need to learn new languages, no new skills, just a few commands and away you go.
NativePHP is the library. Bifrost is the build and release service, getting apps into the stores faster than anything else.
This month we're planning to release the first fully open source version of the Mobile package.
How's it going?
We've sold over 2,000 licenses since May. We built Bifrost over the summer and it already has almost 300 monthly subscribers.
We just gave away another 1,000 licenses to the African PHP community.
Clicking items in the tensors explains where they came from and where they are used in the output. The input tensors can be modified too.
It's a one-man side project that's been half building the site framework, and half re-implementing pytorch functions in javascript. Plenty more functions to go, but hopefully people can already find it useful. I'm planning on doing a Show HN once I've added ~10 more functions.
Posting this from a throwaway account because my main account is locked due to `noprocrast`!
Solo-building this project for some time, going to launch the first version in a week or so!
https://elmo.dev - a tool that automatically builds a searchable knowledge base around your project based on your conversation with coding tools.
It works automatically and doesn't require your attention. To build KB it uses same tool as you (claude/codex/gemini) so it uses the same quota and you don't have to pay additionally for the AI running it.
The result is ./elmodocs directory in the root of your project. You can reference CLAUDE.md/AGENTS.md/GEMINI.md to this directory or directly include the whole directory or its parts into the coding context.
Fluxmail is an AI-powered email app that helps you get done with email faster. I think there's a significant opportunity for AI to change the way we use email, and I'm experimenting with ways to improve the status quo. I'd love to hear what features you'd like to see in such an app!
This is a job board for AI jobs and companies. The job market in AI is pretty hot right now, and there are a lot of cool AI companies out there. I'm hoping to connect job seekers with fast-growing AI companies.
I am launching (tomorrow) a service that helps builders and businesses fix their vibe coded apps and get them production-ready and integrated into their organization:
After that Deus Ex remaster fiasco, I wanted to see how the famous Unreal 1 dithering technique would look on Quake's software renderer. Getting a clean build of it on Linux was fun in itself: https://github.com/klaussilveira/exp-quake
I'm building Table Slayer[0]. It provides tooling to display battlemaps on TV-based tabletops for games like Dungeons and Dragons. The source is open[1] and it's built with Svelte, Partykit, Turso and Three JS.
I'm currently building a prototype hardware component (essentially a large format touch screen) that people can purchase alongside.
Every two months there’s a 15-day tournament where 670 rikishi(sumo wrestler) fighting ~160 matches each day. I’m recording all the results and kimarite (winning moves) into a browsable database with charts and videos.
Recently I have been using Gemini to process and edit the daily match videos. It works surprising well. It can detect the start/end of each bout, recognise the wrestlers and assign the correct rikishi id to them.
Still early, but if you want to get into Sumo feel free to join! Its fun to watch and the matches are quick!
Sumo fan here, this is cool. UI is great. I assume you know about sumodb? I don't say that to discourage you, but people are tracking stats.
Since you are good at UI, here's something I would really like: a Natto-style page for each bout that I can manually page through as I watch the basho. Since Natto is underground, I have to watch the basho on NHK or Abema or via Kintamayama - all fine, but I miss the Natto graphics. If you could do that in a way that I could tap through each match, I'd use it every day of the basho and I think so would everyone on r/sumo.
BTW if you don't know what I'm talking about, reach out and I will explain.
I was testing something like this with https://sumostats.com/live (a second-screen style page, so you can quickly look up the current match and it follows along live).
But I think I know what you mean... I'll check out Natto graphics again (haven't seen it in a while) and will try make something up for next basho!
A newsletter based platform that gives daily news briefings on countries using the local language news. Called Lexica News it’s working pretty well so far. Users are mostly international business execs, diplomats, etc.
Mostly organizing my dotfiles across Windows, macOS, Linux and BSD, however, I have really fallen for Ansible. I discovered at work awhile back, but was able to grok how to make and run a playbook, and I've been hooked since. It also finally allowed me to click the difference between Imperative and Declarative programming!
An open-source protein/molecule viewer, molecular dynamics sim, and general structural biology toolkit, written in Rust. And an ecosystem of libraries to back it up.
Yesterday I proved the infinitude of primes, which I was pretty happy with. https://www.philipzucker.com/knuckle_primes/ A trivial theorem in the scheme of things, but one for which z3 certainly can't do it on it's own.
In the recent years, I discovered the joys of self hosting. What started with a single Plex server for my movie collection became a growing suite of open source applications that became my own personal cloud.
At the same time, I quickly ran into several of the limitations involved, ip addresses fluctuation, limited up speed on residential internet, electricity problems, you name it.
I didn't want to pay the crazy prices required for a dedicated server on AWS, and my storage needs were much greater that I was willing to pay for.
So I started a local business that allows you to run your own mac mini and access it with a dedicated ip for whatever purpose you would like: https://www.minimahost.com/
I'm hoping that over time I can grow it to a point that it could replace my software day job.
Oh, and I am about 3 years into an online mobile battle game. Hoping to publish in the next year or so.
I’ve been building Flare (https://www.getflare.app/), an app for people with chronic skin conditions (eczema, rosacea, etc).
It lets you log symptoms and triggers, but the bigger vision is being able to discover patterns, ask questions about your own data, etc.
Being able to answer questions like “Do my flare-ups correlate with stress?” or “What foods make things worse?” backed with personalized data has been helpful with my own flares.
Still early, but curious to hear thoughts from folks!
I thought that most of the use cases for such a library could be boiled down to a single function that can wrap throwable pieces of code and convert their result to a Result type and that's exactly what I implemented.
I also wanted minimal amount of methods for the Result variant classes and delightful method names so I tried to do that and I'm happy with the results! (no pun intended)
It's just a little side project, not much thought has been put inside of it except the core idea behind it that I just explained.
I am working on LakyAI, https://lakyai.com, marketing platform to build brands. It's a mix of WordPress and Buffer in a way. Great for people that want to blog but also get some distribution and social media help. If you want to try it, please DM me at x.com/strzibnyj
I’ve been working on [Vizzly](https://vizzly.dev) -- my attempt to make visual quality part of the development workflow, not an after-the-fact testing phase.
Most visual testing tools spin up a recreated environment (copy the DOM + assets, render in their own infra) and then compare diffs. The problem is: that’s not what your users actually see. You end up debugging rendering quirks in their browser instead of yours. I wrote about it here if you’re curious: [Why Visual Testing Needed a Different Approach.](https://vizzly.dev/blog/why-visual-testing-needed-a-differen...)
Vizzly flips that around by focusing on developer workflows first:
- Local TDD: vizzly tdd lets you iterate on UI changes locally, instantly, against real screenshots.
- Bring your own screenshots: Works with whatever infra you already have (Playwright, Puppeteer, BrowserStack, CI runners, etc.).
- Team review: When you push, every commit builds a visual review dashboard with position-based comments, review rules, deep links, etc.
The CLI/SDK are open, you can even use just the local TDD bits without ever touching Vizzly’s hosted service. The goal is to close the developer ↔ designer gap by making visual review a normal part of shipping features, not a separate QA checklist.
Would love feedback from folks who’ve wrestled with visual diffs before. Does this workflow resonate with you, or do you see gaps I should be thinking about?
I'm working on Habitat. It's a free and open source, self-hosted platform for communities to discover and discuss their local area. The plan is for it to be federated.
In the last month or so I've been solely focused on plans and content for my instance for my local town, so there hasn't been any programming for a little while but I'll be jumping back into it in weeks to come.
It started as a solution to LLM front ends having terrible native branching features. But slowly I realize most of our data will be going through LLM's so Yggdrasil is evolving into a platform which consumes all your LLM queries, while keeping it easy to query and reference.
And now I have begun to realize how detrimental LLM assisted coding can be to someone who starts depending on it too much, so Yggdrasil is a bet in the other direction as compared to mainstream. Instead of agents/AI doing everything I believe human + ai assistance will win in the end.
Yggdrasil has a simple agent called Valkyrie, so they have their place, but that I believe should be the last step, after the developer has discussed and planned thoroughly through our tree interface, Heimdall.
And if someone replaces the dev, they can browse their conversations with the LLM, observe their mind map, what questions they asked, what extra things they considered (branches), the whole thought process easily navigable and visible.
Personally after using Yggdrasil, I feel quite confident in using the LLM, as I can ask all the silly questions I want, without worrying about context pollution. It aligns really well with the natural exploratory tangential thoughts we have when trying to find solutions or learn something.
Typing is an extremely underrated skill and especially in the age of LLMs, it is the bottle neck in a lot of cases.
I’ve never been fond of existing typing apps; excessive ads, typing random words, etc so I built my own.
You can practice typing code, use your own text, etc
We have a paid plan for features where you can type natural text that targets your weak points (via SmartPractice) and many others. Other than that, it’s both free to use (and ad-free)
I'm actually in the middle of a complete redesign of the AI layer, but there is a POC video linked from the GitHub README that demonstrates the interaction I'm going for using an earlier version. The POS is a very bare-bones system where the "kernel," as it were, is implemented in Rust. There's an MCP atop that to allow the AI and UI layers to drive the POS. Stores may be implemented as extensions that plug into the POS kernel, and that's where language, currency, item databases, and such are defined. The AI cashier knows what items are for sale, how to modify items (in a restaurant context), how to translate from other languages, how to interpret what the customer actually wants, and seamlessly lead the customer through a transaction.
The current code is quite ugly and full of a lot of unfortunate hacks, but it was a good education. The new design puts the AI much more in charge, without as much code-level orchestration. I'm applying a lot of my knowledge from the retail POS and self-service checkout domains to this, as well as learning a lot about applying AI to a "legacy" software domain.
Since last year i've been working on something that surprisingly didn't exist before, an app where you can rate sports games.
https://rategame.io/ and on the app stores(I really recommend the app if you want to check it out, especially on a phone)
We've expanded on the concept with rating stadiums, creating lists, voting for player of the game and more as we are trying to become the letterboxd for sports.
wow.. this is cool. what's the endgame? I built a site that logs my lifetime in person attendance along with statcast tracking for homeruns, launch angle and more. wonder if theres some crossover
https://baseball.willbaxter.info/
The endgame is to become the ultimate source of truth regarding the quality of a sports game.
Dreaming big with hopes of becoming a household name similar to imdb or letterboxd.
Looking at your site I think you would like to hear that when rating games you can mark a game as 'attended', 'watched' or other categories to show others how you experienced the game or just for your own personal log.
Other than that we are light on classic sports stats and our stats are more focused on the user ratings of the games rather than the game stats.
This has been my passion project for the past 4 years, and I finally launched it recently. It’s starting to get some real users, which has been incredibly rewarding.
The idea came from my frustration every time I tried to build a web service. No matter which API service or cloud provider I used, designing databases, deploying and managing backend infrastructure always felt too complex and not much fun. So I built a backend API that just works out of the box, directly from your frontend project, with no backend setup or deployment required.
I sometimes wonder if the world really needs another backend API in this new “vibe coding” era. But since everything can be done from the frontend, it also fits naturally with coding agents like Claude Code.
For now, I hope my APIs would help web devs skip the backend headaches and spend more time on the fun part like building the frontend.
A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use.
There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used.
When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.
I’ve been working more on the unit economics of my data union/trust idea (https://wherelabs.info/).
What I’m trying to understand is whether it is viable to pay people ~$5 per week for sharing their location data and demographics based on a 90% share of revenue from sales of data products built on that data. (But without ever selling or exposing individual level data).
https://weexpire.org - An opensource tool for creating emergency notes that can be read by your trusted contacts only after your death or if you are seriously injured.
Not sure you need psychology to figure it out: the notes may contain passwords to your accounts, confessions, and other things you're not comfortable sharing when you're alive.
Thanks! We're hoping to get the online stream going by the end of the year. We have a _ton_ of programming submissions but its going to be a challenge to get it all scheduled.
I'm building out a new website for it right now too. Hoping to launch that soon.
In June, I shared Marches & Gnats (https://mng.quest), a programming puzzle game (similar to Advent of Code) where you solve challenges using a Turing machine.
Since then:
- I added 13 new quests, from arithmetic basics to Elementary Cellular Automata and Sudoku.
- Rewrote the Turing machine core in Rust, making evaluation much faster and able to handle heavier tasks.
- 102 players have joined, submitting 15000 solutions; 10 players have already solved every quest.
The hardest part turned out to be the storyline. I use ChatGPT to draft outlines. It does it quite well, but shaping them into something with real depth and atmosphere takes far more work than I expected.
Another challenge: since it's a competitive game, players quickly explored the edges of the rules. For example, submitting very long solutions that use transitions as a kind of memory. I love that kind of creativity, but it also undermines the original goal of solving a puzzle as efficiently as possible. So I've spent quite some time balancing mechanics to reward creativity without encouraging loopholes much.
The most fun part, though, is still inventing new puzzles.
Empor.top - https://empor.top the stories of top companies. Highly engaging and readable long form stories (AI generated). Primarily, I made it for myself but in the last 30 days I got >10k hits so I'm contemplating making it a full blown project.
Pretty cool! Are you scraping the data first to pass it to an AI or letting it do the entire thing by itself? Also, if its the latter, are you using a multi-agent framework? Only asking because it seems way too detailed for a single input-output sequence!
I've been working on a tool to add long term memory to various AI tools. It started last year as a small scratch-your-own-itch side project. After using ChatGPT Plus for a month, I went back to TypingMind, my go-to AI client at the time, but I really missed the memory feature and wanted it there. So I made a simple memory plugin for it.
Over time, the project has grown to now support more than 17 platforms, thousands of users, and has been growing organically.
As of most recently a major feature I've been working on is full chat history based memory. Being able to remember and recall every conversation you've ever had across multiple supported AI tools, similar to the reference past conversations feature in various AI apps. This has been pretty intense and fun. Ingesting tens of millions of tokens per user, and doing complex multi-stage RAG on-the-fly across this vast dataset with a tight latency target for UX.
Another project is a RAG app that's built specifically for books. No "we work with your receipts, and legal documents, instruction manuals, product documentation, lecture transcripts, your dogs novel, the script for a play and everything else possible". I wanted something tailored for books, specifically, non-fiction books. When you try to work everywhere, you can not deliver an amazing experience for any one specific use case. AskLibrary is tailored for non-fiction books, so everything from the answer generation pipelines, to the ingestion pipeline, and various other features are all designed for this specific use case. https://www.asklibrary.ai
I am working on Octelium https://github.com/octelium/octelium a FOSS unified zero trust secure access platform that is flexible enough to operate as a modern zero-config remote access VPN, a Zero Trust Network Access (ZTNA)/BeyondCorp platform, an API/AI/LLM gateway, an infrastructure for MCP gateways and agentic AI architectures/meshes, a PaaS-like platform, ngrok alternative, and even as a homelab infrastructure. It is basically a unified, generic, Kubernetes-like, zero trust architecture (ZTA) for secure access and deployment, that can operate in many human-to-workload, workload-to-workload, and hybrid environments.
I actually did a SHOW HN exactly 3 months ago and received lots of invaluable critique regarding how dense, overwhelming and unreadable the docs and repo README were. I've actually spent a lot of time trying to improve the quality of the docs and README since then. I'd love to receive any feedback, negative included, regarding the current overall quality of the docs and README from whoever is interest in that space.
Lately I’ve been telling my friends I’m done. I’ve entered my George Carlin phase. Words don’t seem to mean anything anymore. YouTube titles? Clickbait. News headlines? Clickbait. People say this and that, and in the end it’s nothing like what they promised.
And then this... love the idea!
When I loaded the page, the first thing I saw was some antivax garbage. Is this one of these things where "each sentence must be true" is twisted to the point that every lie becomes a truth?
I’ve been working on a few utility libraries to make it easier to develop web services, basically exporting packages that I find myself using or rewriting often and exporting them as their own modules.
I’m working on https://github.com/hxtk/aip as a collection of libraries giving safe default choices to implement Google’s API improvement proposals in ConnectRPC services. It borrows (with attribution per the license) an unexported implementation of AUP-160 filters from the LuCI project, and I intend to expand it to support data sources other than SQL databases and page tokens, and it also exports an implementation of AIP-161 field masks (which have different semantics compared to standard field masks) and middleware to help with using them for AIP-157 read filtering. I intend to export more middleware that I use frequently, but I don’t know if it’ll live in this module or its own yet.
I built a fantasy football rankings app using claude code, and it has been blowing up in the fantasy football subreddit. Funny enough, it's forcing Yahoo to change their site and improve their layout which ruined all my automation. Surprised how much traffic it's receiving every week just for a better layout.
I'm working on something completely different, especially for me. After 9 years as a CTO I'm moving on to coach other tech leaders. I just noticed that I didn't like the doing anymore and I'd much rather work with people for people. My biggest takeaway is that the hardest part of building anything is the human side. Emotional baggage, limiting beliefs, social dynamics. All the startups I was part of didn't take off mostly because of this. Pretty interesting to see how our automatic actions driven by unidentified beliefs drive everything we feel, think, and do. So I guess I'm moving into hacking on humans now for a living. Feels exciting.
I'm still very early in building the website but you can say hi or read more about my approach or story here: https://trueselfcto.com/
I'm always open to chat about just anything, so please feel free to share your thoughts or say hi!
For me, I'll probably send an email later to support to ask (no rush, since it's out of stock anyway), but I was checking for info on compatibility with Yamaha (e.g. my Cross Connect) ebikes. It's not on the compatibility list. They make their own (mid-drive) motors (PW-SE on mine I think) and proprietary batteries. They pulled out of the United States market altogether so getting more batteries from them again is doubtful. (Mine currently charges to ~85% and then throws an error code, but it still works for now.) It is a Yamaha 500Wh36V battery pack on the down tube with 3 wires (I just unscrewed where the battery plugs in to see).
I've spent the last couple of months porting the compiler from Julia to TypeScript. That's nearly done, so I'm hoping I can post an interactive web demo next month!
I’m writing a Python framework to create Python home automation scripts driving Zigbee2MQTT with as little boilerplate as possible.
https://pyziggy.github.io
The way it works is the user registers / imports MCP (Model Context Protocol) servers they would like to use. All the tools of those servers are imported and then the firewall uses structured LLM calls to decide what types of action the tool performs among:
- read private data (e.g. read a local file or read your emails)
- perform an activity on your behalf (e.g. send an email or update a calendar invite)
- read public data (e.g. search the web)
The idea is that if all 3 types of tool calls are performed in a single context session, the LLM is vulnerable to jailbreak attacks (e.g. reads personal data -> reads poisoned public data with malicious instructions -> LLM gets tricked and posts personal data).
Once all the tools are classified the user can go inside and make any adjustments and then they are given the option to set up the gateway as an MCP server in their LLM client of choice. For each LLM session the gateway keeps track of all tool calls and, in particular, which action types are raised in the session. If a tool call is attempted that raises all action types for a session, it gets blocked and the user gets a notification, which sends them to the firewall UI where they can see the offending tool calls, and decide to either block the most recent one or add the triggering "set" to an allowlist.
Next steps are transitioning from the web UI for the product to a desktop app with a much cleaner and more streamlined UI. We're still working on improving the UX but the backend is solid and we would really like to get some more feedback for it.
There was "choker" back in the day, which I actually never heard about since I wasn't into chess back then. But (1) there was no web version, and (2) it had a specific gameplay that seems too slow for my taste. My version is highly customizable on the setup/rounds/rules, too. From my research, the original was also overrun by bots.
Looking up choker online I found this reddit thread:
> It’s a cool concept, but terrible app design and it’s all just bots you connect with, making it terribly easy to win almost every game
It sounds like this game needs a better AI opponent then? I don’t know anything about this game but something that learned from your gameplay and figured out how to beat you would be very cool.
I already have a better chess engine at different skill levels for 1-player mode. For two human players, I plan to start with sending a link to a friend given there won't be enough random players on the website to find one in real-time.

Been thinking a lot about tools for modern musicians/artists/producers. Not tools for creating the music but tools for communication. Email subscriber lists, event creation (image and text) combined with ability to generate QR codes and send them with easy to use dashboard, some kind of insights into the QR scans, merchandise (integrations with Shopify), hn style link aggregation around music.. been building it with my son who also becomes my product manager since he the one using the tools. For now a private repo consisting of a rails API and a react TS frontend app. Everyday I come up with some small improvements in my head but alas not enough time in the world. With the day job an all, this is purely a passion project and a way to help my son follow his passion, putting on house music events and DJ/producing. If anyone interested, plz reach out contact@kushtybuckrecords.com
I might be taking a contracted job to help provide AI/ML guidance for a friend's company here soon, but all I really do is use ChatGPT/Claude Code a lot and don't really have explicit AI/ML tool building experience. They know this and mostly just want me for competency and comfort going from 0-1 with a new project, but I'm still pretty nervous! So I'm trying to conjure up some simple ideas to inspire me to learn :)
Currently trying to predict student absenteeism in the future based on historical indicators with synthetic data using basic ML modeling and then using LLMs to generate helpful guidance for relevant parties. Basically letting parents know there's concern and citing leading indicators.
Not sure what I'll do next, but hoping to come up with a few other ideas to put my mind at ease. It's fun having some actual motivation to keep up with the current hype instead of just being a consumer, though!
I have a lawyer friend who’s complaining about versioning… but she also mentioned that Word is the de facto standard. What I’m trying to say is that this should be a Word addon.

I'm working on a python library that allows you to put data on GPU as fast as your network/storage allows you to at the hardware limits. No more clunky DataLoaders that are too slow and have inconsistent perf. I achieved stable throughput numbers >8GiB/s (so saturating my PC's nvme SSD), going to test on networked scenarios soon.
Works for any python ML library (torch, tensorflow, jax, etc.), both for training/inference, single/multi GPUs on one node (shared/separate queues for DDP), multiple sources of data, seamless transition between training/validation phase (no significant perf drop), arbitrary shape of tensors and lots of data configurations.
Planning to add (de)compression and on-the-fly data augmentations and releasing it to public.
Scrolling Stock Price "LED" Ticker for Windows. I could never find one that did what I wanted so with the help of Copilot I built my own. Still has some bugs I am working on but I would love some feedback!
I've been building https://carryless.org, a pack manager for people liking outdoor activities (and ultralight weight wheenies). It is focused on user experience, clean and simple UI. Open-source[1], free forever. Here's an example of one of my packs: https://carryless.org/p/Q22oPD3V
It's basically inspired by LighterPack[2], but LP is left abandoned and the UI is quite hard to work with, unfortunately.

You just upload a picture and pick a design type and it generates a thumbnail for you. Got good feedback last time I posted, steadily and slowly growing now.
A webscraping / data pipeline to get the .pdf "Explanation of Benefits", "Proof of Coverage", and "Drug Formulary" for every Medicare Advantage plan in the USA
These docs are gonna be used in a product for medicare brokers (if you are/know one please reach out open enrollment starts Nov.1!), and the pipeline is horizontally scalable to ingest updated 2026 plans overnight @ start of open enrollment (though some companies are posting updated plans earlier)
There are some clever tricks at play but mostly it's bog-standard browser automation; I'm also in an interview process with 2 entities (one funded startup and one massive corporation) talking about web automation roles, and while it's frustrating that they're moving so slowly it's working out to give me time to build this well.
The idea is to see how far an agent can go in replicating and automating the work of a hedge fund.
The project is for educational purposes only, not for real investment.
Here’s what it currently does:
- Runs a user survey to understand investment goals.
- Creates a personalized strategy.
- Builds a portfolio aligned with that strategy.
- Analyzes the portfolio using financial APIs, tax diversification, and client alignment.
- Provides a detailed portfolio analysis.
WithAudio a one-time payment, desktop text-to-speech app that helps users read better by highlighting text as it's spoken.
Current Challenges:
Technical: It's difficult to consistently parse text from various document formats. The I also wants to expand to more platforms but I know I need to focus on marketing.
Non-technical: The product has seen some success with minimal marketing, but I keep getting distracted by spending too much time on technical work. I know I need to do more for marketing but I keep going to my safe space (my IDE).
I believe in the product but it keeps reminding me how difficult is to get somethig to a polished, finished state for all users. 90% of the project takes 90% of the time and the other 10% takes another 90% of the time.
Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation.
The bigger picture: Certificates are often the only tangible outcome of a learning experience. By making them verifiable, permanent, and easy to distribute, organizations save admin time while learners get a trustworthy credential.
Status: Running for 2 years, used by schools and training centers in Latin America. Now building AI-powered features for design editing and data extraction from PDFs.
I wanted to figure out the simplest, most lightweight abstraction, that unifies static site generation and web server for both HTML, JSON, etc. What I arrived at is ~700 lines of TypeScript:
In a docs-first approach, before building the framework above, I actually first wrote the following guide where you build a static blog, and implement a to-do list app: once with plain JavaScript, then reactively. Finally, you run a server with a REST API, and learn about caching and different architectures:
I've been working on writing two appendix sections on knowledge distillation and reinforcement learning for Machine Learning for Drug Discovery [1], which were initiated as tangents to expand coverage of material from a few earlier chapters. I hope to also write these appendix sections up as freely available articles (at least in a condensed form). Thankfully, I'll be able to finish the knowledge distillation section this month but, unfortunately, I need to pivot to finishing out chapter 11 to stay on schedule for full publication.
I've been wondering for years if historical magazines/periodicals could ever be transformed into a modern ebook format. PDF doesn't cut it, but most other efforts are unsatisfactory... part of what makes a magazine a magazine is the rich, mixed content. So, for the past few weeks (months?) I've been taking a stab at it with the science fiction pulps. Started with Analog/Astounding, and I was able to re-typeset the cover (with original art), most of the interior, many of the ads, and so on.
trying to build a webapp where i apply some recommender systems knowledge to TCG deckbuilding. MtG in particular is suffering from product fatigue and as someone who is both an MLE and a casual MtG player, it has been a fun challenge to apply my skills to a domain of interest
It's less focused on the social, more on the jobs. With a limit on the number of job applications a user can make; sort of like Twitter, for job application count. And mechanisms to provide feedback to users. Basically trying to address a few shortcomings of LinkedIn as I see them (with other mechanisms in the pipeline).
But it has neither any jobs, nor candidates.
I'm not sure what the strategy should be to resolve that. I've tried a few things that haven't worked out yet.
In the last 7 days I implemented a complete XPath 1.0 parser & evaluation system from scratch in C++20. Right now I'm adding support for XPath 2.0.
Codex in the cloud has been leveraged to do 95% of the work and Claude 5%. We've output 10.5K LoC and 774 individual tests to ensure compliance to the spec.
Lately I've been feeling like we're living firmly in the future. This would easily be an 8+ month project on my own not including the tests, yet we're now on track for completion in 10 days. A min. 25x speed increase is a crazy level of productivity for me and it's hard to believe I'm still seeing articles claiming that AI coding isn't productive.
Partially, but I think it's moreso the W3C spec being so thorough and the wealth of samples online. I found that during code review both Codex and Claude would refer back to the specs for certainty on expected outcomes. Their understanding of how to deal with unusual edge cases was also impressive, so it seems they have a lot of baked in knowledge & training of how XPath works and they draw from that.
I am working on my Go UI library called gooey [1] which aims to be a one stop framework to build webview/webview apps in Go and WebASM.
It started out with bindings for the DOM, Web, and Browser APIs, but as of today I now have custom Web Components support (which is a big deal considering Go's type system quirks).
Tomorrow I'm gonna polish some of the UI components and start refactoring my git-evac [2] repo management tool which is the first app using the gooey framework.
> Components are bad for web accessibility (aria- property fatigue).
I've been using web components as a vehicle to automate and auto validate accessibility aspects as much as possible, because I think the only way to truly make things sustainably accessible is to find a way to unburden the developer by either inferring as much as possible or making validation a natural part of development rather than a separate testing cycle that will invariably cause accessibility support to become out of sync.
It sounds like you might have similar concerns. Do you have any insights to share along these lines for Gooey?
The UI components that I wrote initially are just wrappers for the Browser provided input/form elements. As I'm relying on webview/webview to build desktop apps out of it, that also kind of implies WebKitGTK4 on Linux, WebKit on MacOS, and WebView2 (Edge) on Windows.
These work quite nicely together with a screen reader because you don't have to intercept the focus event (or others) that people browsing in caret mode or similar would use to navigate the page.
Additionally I decided to make single page applications using a main and section[data-view] elements so that the HTML and CSS alone is enough to hint screen readers on what's visible and so that there are no javascript codes necessary to tween things around, the JS/WebASM side of things literally just sets a data-view property on the main element.
The whole idea behind gooey and the way it is structured is:
- all states must be serializable in HTML
- Static HTML and CSS makes the page usable (apart from web forms and REST APIs, that's developer provided code)
- Dynamic WebASM on top essentially translates the DOM to be interactive, so that things can be animated based on changing data or streams coming from the backend. All interactivity is rendered directly into the DOM, so that it can be serialized again at all times.
- Communication between Client and Server is JSON or any other Go implemented Marshaller, and using Fetch API behind the scenes.
I decided on purpose to not provide XMLHTTPRequest and other old APIs because I'm relying on WebASM and "modern Browser engines" anyways. This way I kinda force users of gooey to use modern JS from the WebASM context and I save a whole lot of trouble with compatibility issues (and don't get into the unsemantic div fatigue like React does, for example).
The bindings should also work with tinygo's compiler if you're careful with deadlocks (see docs/ERRATA.md).
Haven't tested the typecasting that's required for the components yet though, they might break because of some generics quirks (e.g. Wrap/Unwrap helper methods).
I'm working on a site that serves as an alternative to Hacker News. There you will find two relevant options (at least I thought so kkk)
1. A notification system. All posts that are commented on or voted on (positively or negatively) will generate notifications on the site for the owners of the respective posts.
2. Diversity of topics. On Comuniq we're not fixated on a single theme, so users who like topics such as health, politics, entertainment, art, etc. will be able to post there and generate very intelligent debates.
We're not trying to take power away from our monster hn, but rather to provide another option where we can talk about other things we love. Check us out at https://comuniq.xyz
I started building Rasterly as a side-project to be able to dynamically visualize drone and satellite imagery of any size. You can calculate and view spectral indexes too!
The goal is to make it really easy for drone surveyors, conservationists, researchers, and so on to share aerial imagery without anyone needing to download anything.
No customers yet. Focusing on improving the performance of the tile server and preprocessing of images, and of course trying to connect with potential users! Struggling to transition into a salesman though.
Cool! How far are you planning to take it? Interpreted mode only? Or do you plan on going the whole HotSpot nine yards with compiling bytecode down to native code?
We want to complete the interpreter and then decide what to do moving forward. The two principal options (and both might be followed) are 1) performance and 2) a separate UI that connects to Jacobin via Websocket or other protocol and enables display/observation of JVM instructions as they're being executed (and of course many of the other observable events).
The biggest hurdle we've faced is the vast number of native methods called by the HotSpot JVM, which need to be reproduced in go for a go-only JVM. I think we've spent as much time working on the native methods in the various libraries as we have on the JVM proper. By our analysis, the JVM calls a total of 1800 native methods. Many won't be needed by us b/c we use go's garbage collector and we don't implement the security manager (which Oracle is deprecating)--but that still leaves quite a few.
Still working on https://theretowhere.com, which is a website that makes it easier to find apartments and hotels/airbnbs close to people and activities you care about.
The past couple months have been fun since I've implemented a lot of new highly-requested features into the site's city heatmapping capabilities. One thing I've found motivating is having my own private changelog that shows screenshots of feature requests people have given me, and then dates for when I finally finished those features.
It's easy to forget how much stuff you've built in a month or two, sometimes.
I'm working on a Heroku / Render / Flyio alternative thats free, open source, built on top of Kubernetes for about 2 years now.
I’ve found these services charge way too much per GB of memory (10x more than IaaS providers), but more importantly, offer terrible flexibility. You can’t schedule multiple apps on the same instance, and there aren’t many instance size options.
Canine also supports deployments of any helm package (postgres, airbyte, dagster, etc) via helm charts.
I’m working on some more QoL and adding more puzzles, I’m surprised how quickly everyone completes the current ~60 levels. A better tutorial is in the works too. If you have any other ideas, feedback is very welcome.
I’m also working on another app, for building social media carousels; it’s currently awaiting app store review, so I’ll show it later.
Often, when I use generative AI to produce videos, the results are close to what I envision but rarely capture my imagination exactly. Prompting the AI to fix specific details can be a cumbersome and time-consuming process. To address this, I'm developing solutions that make the creative workflow more intuitive. So far, I’ve built an app that allows users to provide visual clues as guides, along with a 3D environment where the camera can be freely manipulated within the generated scene.
The community is moving fast though. Now higgsfield allows using arrows and pointers to edit the video but so far, no one is doing a good camera control visually.
We use Intercom for support and our customers need to upload sensitive docs (think proof of address, bank statements, etc.). Intercom’s native uploads aren’t a long-term fit for us (100MB/file limits, docs live on Intercom’s infra which screams data privacy issues for us) and we need files to land directly in our own storage.
Still thinking about what to include exactly, but we appear to be on the right path!
For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website.
The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc.
I hope this service might be useful to others as well.
That looks great. Are you aiming to automate the gathering process or let users self-serve by creating their own list of bookmarks (then processing the pages on your side)?
Thanks. For now, I don't have any plans to automate this process. Users simply add articles to the site, as in other aggregators, and can filter content by tags.
What would the ideal process of working with this kind of site look like for you?
I'm not sure, my work and hobbies are niche areas of computer science so I find myself wanting very specific filters. That's probably not a requirement for the typical web stack engineer.
“Autotomb” identifies physical objects/artifacts/specimens mentioned in Egyptological (e.g., Giza) excavation diaries then generates (Meshy) 3D model sets based on those descriptions which are deployed in in virtual reality (AFrame). The output is like an immersive word cloud but the words are 3D objects and you can navigate the scene with your body. Still early days but the desktop pipeline is functional: https://github.com/Cook4986/AutoTomb
I’m currently hacking away at a project which turns your keyboard into a clipboard manager, password vault and barcode reader as parts of it. I just need to come up with a better name than totally normal keyboard (:
It has three main parts:
– A simple Zazen (sitting meditation) timer
– Zen readings
– And the main feature: a chat with an AI Zen teacher, where you can ask anything from Buddhist teachings to handling personal problems.
I built this because I’ve always been drawn to the minimalistic style of Zen. ZenPocket doesn't have notification because I am tired of notification-driven apps myself and wanted something simple and clean. Meditation, I believe, can help solve a lot of stressful problems, and adding readings + an AI teacher helps keep my mind stable.
I'm working on a bunch of small tools for musicians. I want to simplify complex musical concepts by giving visual feedback and minimal UI. All modular components built with pure JavaScript.
My one man side project is Prisme Analytics: an high-perfomance, self-hosted and privacy-focused web analytics service.
I'm working on improving UX and simplifying deployment a lot. In the next release, a single docker run will be enough to get a working web analytics service with minimal resource usage.
I got tired of Spotify recommending me the same songs, from the same artists, over and over again.
So I built Riff Radar - it creates playlists from your followed artists' complete discography, and allows you to tailor them in multiple ways. Those playlists are my top listened to. I know, because you can also see your listening statistics (at the mercy of Spotify's API).
The playlists also get updated daily. Think of it as a better version of the daily mixes Spotify creates.
Right now it's not possible, but I'll put it on my list of features to add. Unfortunately though, the play history Spotify provides is very innaccurate and incomplete - so suggestions only based on that would be quite limited :( It's the same issue with the statistics, they are best-effort based.
Having said that, there is another feature you could use: if you have or follow any playlists, you can include artists from them. Make sure to have the `Index Playlist Artists` option (it will get enabled automatically if you follow <100 artists) and tick `Include playlist artists` setting when creating your playlists.
Another question: instead of getting my follows from my Spotify, could it let me type the artists I'm interested in?
I really want to use it (I'm also not happy with Spotify's recommendations), but my follow list is mainly for podcasts. Maybe just letting the user enter the artist names (instead of getting them from Spotify follow lists) would be easier to support?
Not currently, no - I might potentially include it at some point, but I feel like the Spotify UI is better tailored for that, so I'm not sure.
The current functionality revolves around genres, and artists are derived from those selections. There are some additional filters where you can filter down based on album/track release dates, exclude genres or specific artists - but it all comes from your library, not from the whole Spotify pool. It was a deliberate decision, as my gripe was the fact that I have a massive library, and was not listening to its entirety.
You can achieve a somewhat similar functionality by creating a playlist, and adding a single song from any artists you want in that playlist.
As to the following list - the podcast/artists libraries are not the same and you can access them at different places in Spotify. If you click on your profile and go to following you'll only see artists/friends. Moreover they are behind separate APIs/access scopes and I only scrape the aritsts you follow.
If you want give it a go, you might find it useful. You can delete your account at any time - I don't keep any of your data once you delete your account.
I'm building an app to help people memorize Kanji by turning the characters into vivid, memorable images with accompanying mnemonic stories.
I think AI image and video models have reached a point where they can offer a completely new approach to language learning.
Next, I'm planning to add features that use AI to generate comic strips (using Seedream or Nano Banana), songs (using Suno) and videos (using Veo 3 or Seedance) to make learning Kanji even more engaging.
There's one shown in the video (and which appears for 1 second after waiting 5 seconds for it to be generated) and 3 static ones below (two out of which don't really correspond to the text menmonic below the image).
I've been busily porting my NES game, Tactus, to Windows, Mac, and Linux as a "native" build. It's been fun to consume my own emulator as middleware, and then lightly modify it to support things like a widescreen view, which the original console definitely cannot do. Here's what that looks like:
Right this second I'm getting the paperwork sorted to start my first business (gulp!) which should then let me get a Steam page set up and start messing around with the Steamworks SDK integrations. Tons more work to do, but it's coming together fast.
Even more exciting, the cartridges are finally working! I can play the game on real hardware. :D It's basically the same game code on both platforms, with the PC build just doing a bit of extra work to signal to its emulator "shell" that it has switched game modes. (This affects the widescreen display.) Real hardware capture here:
Codexes Factory: algorithmic tools to create, operate, distribute, and market entire publishing imprints. This week I am launching my first imprint, Xynapse Traces, with 66 books in the Korean pilsa (筆寫) style. Later in October, Nimble Ultra, devoted to the history and practice of intelligence and espionage. Last week I built a giant collection of 575 imprints that are a shadow superset of the ~540 imprints operated by the Big Five publishing houses (Penguin Random House, the largest has ~300). Teeny weeny tip of the iceberg at NimbleBooks.com.
After leaving active involvement in a still-extant biotech I co-founded in 2020, I'm focusing on some ideas I've kicked around for awhile but didn't have time to work on.
The first is a document search system for over 200,000 high quality OCRed pages from successful CD/DVD-ROM products I developed some years ago, covering the official records of the American Civil War as well as 19th century documents on Native American history. The technology stack involves BaseX for indexed document search, Postgres for user data, Redis for transient session information, and Blazor WASM for the UI. (I coded all of it.) It can be seen at https://allhistory.us (currently desktop oriented.)
After working extensively with Coda (and much less with Notion), and becoming frustrated with its limitations, I decided to work on a considerably more powerful and programmable system to compete with both. No externally viewable progress so far, but soon ...
I'm developing on a new system I assembled, for general development but also to be able to seriously work on local AI - an EPYC 9755 CPU (128 core) on a Supermicro motherboard, 384GB RAM, and an RTX 6000 Pro Max-Q. I also have ideas for some AI products but too early to talk about.
Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI.
I am currently working on a new mode that is more like what played walking around: a few rounds in rapid fire, very little time to think before the next round.
We are building official.page, a digital platform for creating a permanent online presence. Think of it as a personal knowledge graph where your thoughts and projects are connected and always discoverable—no matter how much time passes. It's a way to build a public record of your work.
To know more and discover more about the project, please visit:

I've been working on raytraced lighting in the Bevy game engine, using wgpu's new support for hardware raytracing in WGSL. The initial prototype is launching with the release of Bevy 0.17 tomorrow, but there's still a ton left to improve. Lots of experimenting with shaders and different optimizations.
At work we have an MCP that is mostly a proxy to our API and it was a little tricky to get it hooked into our regular CI/CD regression testing so I thought a dedicated service to track MCP server statuses could be useful.
Hacking away at it slowly.
So far it has ping monitoring, tool validation, resource checks, SSL and DNS / HTTP header tests
Hoping to get protocol version logging, custom tool-call monitoring, response schema tracking in relatively soon.
Focusing on ergonomics improvements. Just released an improvement to the __repr__ for Invalid types.
Potentially working on expanding the ability to generate validators from arbitrary typehints, ie `get_typehint_validator(list[str | int])`. It has good coverage, but I suspect I'm blind to some obvious holes. Would love feedback!
It's not the core of koda-validate, and yeah lots of libraries have a similar capacity. Feedback I'd be interested in is if there are gaps.
In general the value prop of koda-validate is that it turns validation into typesafe building blocks, which makes validators very re-usable -- and flexible. Some other notable differences from pydantic are that it doesn't `raise` on validation errors, you don't need a typing plugin, and it's fully asyncio-compatible.
- Active recall studying app that allows a user to practice active recall[0]. The app hides user provided content at first and asking the user to try to remember all they can before reading the content. Then the user goes through the material slowly revealing each paragraph from their input. At the end they try to actively remember what they learned and can even compare to what they knew at the start.
- Mixtape sharing platform for midwest emo[1] which is a genre I've really gotten into over the past few years. The community is pretty strong on YouTube for creating "mixtapes" so I wanted a spot that was just for these videos.
- PhotoForge[2] Photographer's companion app which can help me choose photos using a Tinder-esque swiping mechanism. It also has some AI stuff for generating Instagram descriptions. Finally has a watermark tool. Still trying to think of other stuff to add. This was an AI code weekend project so it's like a house on stilts at the moment but I plan to give it some more love soon
In my free time I’m still working on My Financé (I keep getting feedback this name is confusing), which is a fairly undifferentiated personal finance tool.
It’s a labor of love, but I love it!
I’m currently building a simulation engine that lets you forecast your spending, build scenarios (like taking a year off, getting a cat, move to a new city, etc based on your current spending patterns and assets.
I don't know what it is about this name, but I read it as "My Fiancé". My brain did not register the first "n" and it wasn't until I read your parenthetical remark that I went back and re-read.
The name isn't confusing, per se ("get married to/be exclusive with your finances", OK), but it also isn't very strong... "financé" is also very strange and awkward to pronounce as a native English speaker. Probably because it comes across more as Spanish-seeming despite it being a play on a French work.
I’m working on https://onebliq.com
A lightweight service for Azure cost visibility.
The idea is simple:
* See where your Azure spend is going, without learning all the ins and outs of Azure Cost Management.
* Get alerts when something unusual happens, with the root cause explained right away.
Still in preview, so I’m mostly looking for feedback from people who deal with Azure day to day. Early access is available if you want to try it!
I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output.
The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output.
I like the promise, and it looks nice. But I'm not sure what are the selling points.
- pytest already works with assert. Why brag about something that is already commonplace?
- It could help if your docs explained the alternative to using fixtures. I assume it would be done by re-using givens, but you could make it clearer what is the preferred way to do it, and what is gained, or lost, but doing it that way.
- Can you explain how your diff is better than the pytest diff? (I'm asking as someone who hates the pytest diff)
Thanks for the feedback, it helps me see things from a different perspective.
These are excellent questions, and you're absolutely right that they should be clear from the landing page. I'll work on fixing that.
Short answers:
1. Good point about asserts. When writing the benefits, I was targeting a broader audience (unittest users, people coming from other languages like JS), but the reality is most visitors are probably "pytest escapers" who already know pytest uses assert. I'll reorganize the selling points to focus on what actually differentiates Vedro.
2. The main philosophy is "all you need is functions and their compositions", no special decorators or dependency injection magic. But this is indeed missing from the index page. Will definitely add clear examples showing how to handle common fixture use cases with plain functions.
3. One diff example on the landing page clearly isn't enough. I'll add more comparisons. Since you hate pytest's diff output too, I'd love to hear what specifically bothers you about it, your pain points would be incredibly valuable for improving how I present Vedro's approach.
Because my hate for pytest is ardent and dear to my heart, I will try to explain.
I wrote a very simple function:
def test_whatever():
a = range(10)
b = (10 / x for x in a)
c = list(b)
When I run it with normal Python, this is the exception:
Traceback (most recent call last):
File "test_test.py", line 10, in <module>
test_whatever()
File "test_test.py", line 6, in test_whatever
c = list(b)
^^^^^^^
File "test_test.py", line 5, in <genexpr>
b = (10 / x for x in a)
~~~^~~
ZeroDivisionError: division by zero
It's compact and simple to understand. It pinpoints the exact location of the error, and I easily scan the text to find the function call-stack.
Now here's the pytest error:
___________________________________ test_whatever ___________________________________
def test_whatever():
a = range(10)
b = (10 / x for x in a)
> c = list(b)
test_test.py:6:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
.0 = <range_iterator object at 0x107695e90>
> b = (10 / x for x in a)
E ZeroDivisionError: division by zero
test_test.py:5: ZeroDivisionError
It doesn't pinpoint the error, it adds code lines that might be irrelevant, and extra information I don't care about.
I will say using `--tb=short` fixes most of it, at least in this example, and sometimes it's even preferable, because it's shorter. But it still doesn't pinpoint the error like normal Python exceptions do.
Thanks for the support! It means a lot, especially from someone who shares the pytest frustration.
About bare `assert`s. Vedro is actually flexible enough to use any matchers you prefer, but let me share why I stick with plain asserts:
1. In most editor themes, `assert` jumps out with distinct syntax highlighting. When scanning tests, I can quickly spot the assertions and understand what's being tested.
2. The expressions feel cleaner to me:
assert error_code not in [400, 500]
# vs
assert_that(error_code, is_not(any_of(400, 500))) # hamcrest
3. I like that there's nothing new to learn, the expressions work exactly like they do in any Python code, with no special test behavior or surprises.
Would love to hear what specifically bothers you about bare asserts, always looking to understand different perspectives on testing ergonomics!
Your first and second points makes sense. They don't matter much to me, but I see how others could value those things.
Aside: I also don't like the hamcrest syntax. I also don't love unittest's syntax but it's OK and it's pervasive (i.e., available in the stdlib).
The third point is where I start to disagree more strongly.
> I like that there's nothing new to learn, the expressions work exactly like they do in any Python code, with no special test behavior or surprises.
This doesn't seem true to me.
> the expressions work exactly like they do in any Python code
Not to my mind. In normal Python, an assertion communicates something that is unequivocally believed to be true, not something that may or may not be true (a test). Let me see if I can explain it this way, I often use asserts in tests to show (and enforce) something that I believe to be true and must be true, before the test can have any meaning. E.g.,
The "assert" communicates that this is a precondition, the "self.AssertTrue" communicates that this is a test.
I can 100% see that others might not see/care about the distinction, but I think it is important.
> no special test behavior
Well, that's not quite true. You have to handle the AssertionError specially and do some fairly magical work to figure out the details of the expression that failed. The unittest-style assertions just report the values passed into them.
I don't really like that magic, both from an aesthetic standpoint and from a least-complexity-in-my-tooling standpoint. Again, I can understand others making different tradeoffs.
It supports Claude Code and Codex, but has you constantly working on multiple features in Git worktrees. This way you are always able to stay busy while waiting on your agents.
It has built in tools for review, such as a diff viewer, and a quick button to run your application in different worktrees for testing. It has completely transformed the way I work.
Also working on DailySelfTrack ( https://dailyselftrack.com/ ), an app to track what matters to you in a way that you find relevant. So it is a mix of habit tracker, health log and journal. Like a spreadhsheet app, but with much better UX. And like a habit/health app, but with much greater customization.
I want this to be a tool highly useful for people who have complex health issues, are working towards ambitious goals, or just want to regularly reflect on their day.
I'm building it since I couldn't find a satisfying solution anywhere. It's local first and does not force you into a subscription, or tries to exploit you with any other dark patterns
Everyone’s drowning in long articles, dense PDFs, and hour-long videos. I’m working on https://unrav.io , it lets you flip any article, paper, or YouTube link into the format you actually want (summary, mindmap, podcast, infographic, etc.) in one click.
Right now I’m experimenting with a simple bookmarklet trigger instead of a browser extension. Curious: how do HN folks feel about bookmarklets in 2025, still viable, or do you prefer extensions?
1. COCKTAIL-DKG - A distributed key generation protocol for FROST, based on ChillDKG (but generalized to more elliptic curve groups) -- https://github.com/C2SP/C2SP/issues/159
3. A reference implementation for the specification I wrote last year for federated Key Transparency, so that the Fediverse can build end-to-end encryption (E2EE) with stronger, less-centralized notion of trust than TOFU -- https://github.com/fedi-e2ee/public-key-directory-specificat...
I want to bring their bikepacking adventures alive in a story format. Cycling trips are often not Monday to Sunday. They might be a few weeks! Everything is geared towards performance. This misses the mark a little bit. I made this app to stitch a trip together. It also has a comparison engine which asks questions like - how many doughnuts? - to translate the trip into things everyone will understand.
Turns out HPC GPUs and systems are realllllly hard to find reliabile information about. I've built another project which aims to make this easier. Compare HPC GPUs, Power et al in a single page. Working on a calculator to determine how many FLOPS or GW your DC can do. Executives loveeee this!
My uni is called NUST so I made a better LMS for it called NUTS lms.
https://www.nutslms.com. It's a chrome extension that serves as agentic interface for my University's LMS.
The AI Agent is called "Deez Nust" and it can do pretty much everything a human can do:
- Check deadlines
- Download assignments
- Even do a quiz for you
I'm trying to build a next gen quickbooks competitor.
Something that doesn't nickle and dime you, very cheap (perhaps even open source), has all of the extensibility of a modern ERP, a great UI, and handles complex use cases (revenue rec, expense management, inventory cogs, etc).
I feel like this is solving a real problem, but have no idea how to break into the industry. Just trying to solve my own problems for business accounting but would be nice to know other folks would be interested.
I have been working on my terminal editor, but I parked that for now -- https://github.com/bloomca/love. It is possible to load a file and edit it, copy/paste works, you can select text, etc. The next step is to integrate with the tree-sitter for syntax highlighting and then with LSP, but it took a bit more time than I wanted.
Another project of mine is to play music from my audio CDs by myself. I built a simple Rust library to read TOC and raw PCM data from a CD drive -- https://github.com/Bloomca/rust-cd-da-reader (works on Windows, macOS and Linux), and a ripper -- https://github.com/Bloomca/audio-cd-ripper, which rips all tracks and encodes it as FLAC and fetches metadata from MusicBrainz.
The next step is to play it. I looked into using cpal (https://github.com/RustAudio/cpal), but I feel like using low-level audio API for each platform is a better approach for learning.
My theory of learning is that you learn the characters better if you learn how to read and write them at the same time. And flash cards are better by giving you as much information as possible about the character.
This is fundamentally different from e.g. WaniKani which only teaches you how to read the character and relies on pre-made mnemonics (plus SRS) for easier retention, and from Anki which (normally) has very minimal flash cards, showing only small bits of information per card. When you have the whole dictionary on each card it gives you the opportunity to create the easiest connection with what you already know. This may be some made up story about the components (radicals) in the kanji (like WaniKani does) a word you already know, other kanji sharing the components, etc. The more connections you make the easier it is to learn them.
One of the features I personally use extensively is the ability to bookmark words containing the kanji, which will then pop up at the top of the words section in a later review. If I remember the meaning and the reading of the words I have bookmarked for this character during a reading review, I consider mark card as good. If I remember none of them I mark it “again”.
Adding a chat feature to my iOS app size analysis tool that runs locally on your Mac. My goal is to make everyone a build engineer, where you can chat with your builds and get insights and improvement areas. Testing out on-device Apple Intelligence models but need to find the time to do more validation testing.
Tech side project: crawlers that doomscroll job boards for me, and a Tinder clone that swipes through them. I recently broke out the actual automation logic into something more recyclable for scaling out to new targets (and broke out the HTML parsing for possible use outside my browser automation flow). Still figuring out how I want to handle datasources as both an API and a plugin architecture, but the goal is to eventually be able to configure searches through the API, to manually trigger and/or setup scheduled runs.
Personal side project: extensive cleanup of my family's place. I'm just now approaching a decent first pass at the outside, and have to tear apart a basement next. It's taken most of this year. It's not the specific reason I've farmed collecting search results off to a bot
For-fun thing: CTF puzzles. I'm not very good at them, but they're useful for other things. I fell down the scraping rabbit hole this way, and I'm currently using a series of them to finally get some exposure to Python. I also have a writeup half-written about this exact process
Working on Fraim, open-source agents for cloudsec and appsec engineers to complement existing deterministic scanners. Born out of our 3 years of learnings building such scanners for IaC. Turns out in the real world policies are subjective enough to make this hard.
Examples:
- Policies are frequently subjective. Hard to codify, but LLMs can evaluate them more like a security engineer would. "IAM policies should use least privilege." What is "least" enough? "Admin ports shouldn't be exposed to the Internet." What's an admin port?
- Security engineers are stretched thin. LLMs can watch PRs for potentially risky changes that need closer human review. "PR loosens authz/authn." "PR changes network perimeter configuration."
- Traditional check runs (SAST, IaC, etc.) flood PRs with findings. Security doesn't have time to review them all. Devs tends to ignore them. Frequent false positives. LLMs can draw attention to the important ones. "If the findings are unusual for this repo, require the author to acknowledge the risk before merging."
An extension which treats tabs as a stack - so I can go down a rabbit hole opening new tabs and then use a shortcut to close a tab and take me to the parent of that tab
This is mostly a nostalgia play--I'm pining for a time when app development was much easier. I'm trying to apply lessons from early Rapid Application Development while still providing a full-featured language.
I confess that I haven't gotten any traction at all, but I find it incredibly useful for my own consulting business, so I'm going to keep on working on it.
I had problems sharing my photos on Instagram so I made an alternative:

A comprehensive Prometheus metrics exporter for Gunicorn WSGI servers with support for multiple worker types and advanced monitoring capabilities, featuring innovative Redis-based storage, YAML configuration support, and advanced signal handling. This Gunicorn worker plugin exports Prometheus metrics to monitor worker performance, including memory usage, CPU usage, request durations, and error tracking (trying to replace https://docs.gunicorn.org/en/stable/instrumentation.html with extra info). It also aims to replace request-level tracking, such as the number of requests made to a particular endpoint, for any framework (e.g., Flask, Django, and others) that conforms to the WSGI specification.
Finishing up https://github.com/dimitarvp/xqlite -- an Elixir library for working with SQLite, with the FFI code written in Rust via the `rusqlite` crate.
The Elixir ecosystem lacks a super stable driver for this. I've heard reports that the currently used library -- `exqlite` -- crashes every now and then. I aim to fix that once and for all, with Rust and careful programming.
Last items remaining are to make sure users can get precompiled native library + start doing proper release tagging. The software is functional otherwise.
Cordyceps: A port of Playwight that doesn't use CDP or Chrome DevTools Protocol either over websockets or chrome.debugger. Instead it uses pure DOM and Chrome Extension APIs. It includes a port of both Stagehand and Browser Use that run purely inside the Chrome Extension. [0]
Doomberg Terminal: A Chrome Extension that performs algorithmic trading using Robinhood's web interface and market data. [1]
crx-mcp-over-cdp: This is a proof of concept demonstrating how to run a Model Context Protocol (MCP) server inside a Chrome Extension using Chrome DevTools Protocol (CDP) - no external server required. (Sort of, I left out the actual MCP library implementation. Ran out of time.) [2]
For about two years I am working on dynamically configured, zero-downtime, low-code API and extenaible platform called Hamster Wheel. It is written in C# and today I released first one of few libraries that I developed while working on it:
It is small helpful library that helps to write Roslyn source code generators using fluent API.
Might be a bit niche use, but native Roslyn APIs are a bit complicated to get started writing source code generator. Fluent API helps with that greatly. In example:
- automatically emits using statements
- automatically format generated code
- helps with importing types
- helps with indentation and balancing parenthesis
- helps with adding, using parameters, async methods generation
- provides nicer to use wrappers to Roslyn IncrementalValueProvider
- allows to share pieces of code between files/classes (i.e. interfaces implementation)
An “everything” feed reader. Its a plugable framework that allows you to push anything into an RSS feed reader type interface. Email, Slack notifications, RSS, etc.
I want one place to manage ALL notification settings. So if I want to be notified of Slack messages that contain the word “cat”, I can do that.
I am also looking to add summarization and tagging using a local SLM. Trying to find a method that can run on older hardware.
I am building LookAway[1] - an antidote to seductive screens. Many people have been facing issues like eye strain, digital fatigue, CVS, posture issues, and more due to prolonged screen use and I aim to solve it with this product. I believe managing screen time is as important as managing sleep (if not more).
Since a few months back I am working on a side project to give a snapshot of the regional and global species and natural ecosystems.
I use manual (me) and automated tools (web and literature search tools, llms, visualizers ...) to search, extract, organize and visualize ecosystem literature and data.
If there are some species that are you would like to see a snapshot of, and the region/location let me know and i will try to get a similar visualization.
DM or as reply to the chat.
Share the species name (common or scientific) and location (can be a city, town, region, province, country).
It is a work 8n progress, but I would be very happy to recieve feedback.
I appreciate what you're doing here. I think it's really important to have this kind of high level overview of these species. I have a little feedback based on clicking around the site.
When you click on a country in the map view(under Elephants, for example), I think the map still has focus instead of the card. So this means you can't highlight text, click on links, etc within the card. Also if you scroll using the scroll wheel, you end up zooming in and out on the map.
I wonder if it would be good to have a "see more" link or some such here, so you can view the same information in the card, but on its own discrete page for each country?
Really appreciate that you checked out the website. It is a bit hacky, but for now i am happy with it. Indeed that is correct, the focus is on the map. I am going to fix that. Thank you.
As for the see more, it is in my planning. I can do it manually, but I am waiting for some free time to automated that.
Still working on building a local delivery service in NYC using electric Cargo Bikes, at https://hudsonshipping.co. We're aiming to launch our first pilot in early 2026 in Brooklyn!
A new way for realtors and potential buyers to do property research.
A "trying to solve my own problem" project. Managing my realestate portfolio and getting an unbiased estimate pricing estimate for new locations i'm interested in is tedious. Doing my own research on a location takes hours.
https://realestate.blackboattech.com/ makes this easier converting all real-estate research into a one click affair. Agent automatically accesses the location and neighborhood to score amenities and gets an average price range for similar homes. Research reports are great for consumers and realtors can have on-demand reports generated for the most up-to-date information. Over time the plan is to have passive tracking of my existing real-estate portfolio notifying me of local events or litigations that may affect my property pricing.
Been having a lot of fun building SecurityBot (https://securitybot.dev/), a free security and uptime monitoring service. It keeps tab on your HTTP security headers including CSP, robots.txt, security.txt. open/closed ports, ping times, uptime, and more.
A command-line tool called berk that is a versatile job dispatcher written in c. It is meant to replace big clunky tools like Jenkins, Ansible etc. It has syntax similar to git. It works pretty well, just need to iron out some kinks before final release. https://github.com/jezze/berk
Working on the Restful Atmos Sleep Lamp, a smart bedside lamp that automatically shifts throughout the day and night for the circadian rhythm, reducing blue light at night and maximizing blue light during the day. There is a machine learning layer that learns your preferences and automatically adjusts the intensity of the light, similarly to the Nest Thermostat [0].
Also, shipping Bedtime Bulb v2 next month. This is a hybrid LED-incandescent design meant for the evening that is the best of both worlds: low blue light, high color quality, perfect compatibility with dimmers, 10x less flicker than incandescent, includes near infrared, low energy use, long lifespan [1].
I’m working on designing a system at the intersection of mental health and personal finance.
The idea is simple: stressful or difficult moments happen every day, but they usually disappear with no positive outcome. At the same time, many people struggle to save consistently for the things they actually want (trips, concerts, hobbies) because necessities always come first.
This system links the two: when a user logs a stressful moment, a small preset amount (say $2–$10) automatically gets transferred into a personal “joy fund.” Over time, bad days turn into tangible progress toward something meaningful.
Right now, I’m validating whether people would find this useful before building a product. Curious to hear if this resonates, and what potential challenges you’d see in such an approach.
I’ve been working on https://fontofweb.com, a search engine for real-world web design.
Most design inspiration sites lean heavily on curated mockups (Dribbble) or award-winning showcases (Awwwards, Mobbin). That makes them polished, but they don’t reflect what most production sites actually look like. Font of Web takes a different approach: it sources directly from live websites, and the community can clip specific elements instead of entire pages. That means you can browse navbars, pricing cards, dashboards, etc., not just full screenshots.
Each clip is enriched with metadata (fonts, color palettes, original domain). Search works across that metadata, natural language queries (“minimalist fintech dashboard”), and even visual similarity — so you can find results either by text or by image.
There’s also a Chrome extension to snip and save from any site.
I’d like to hear from designers and frontend engineers: is this useful in your workflow? Anything obviously missing?

Historically, Astro hasn't had an API like renderToString for React/Vue/etc. that takes a component and renders it on the server. That changed with the release of the Container API last year: https://docs.astro.build/en/reference/container-reference/
But there are still a lot of rough edges:
- Importing components is a hassle (you have to go dig through the Astro manifest or create a TS file that exports all your components)
- No Vite integration (so no local dev support, or hot reload)
- No styling support (this is probably the biggest one)
Mighty will provide dev + styling support and a simple way to import your Astro components, with adapters for Hono and Laravel when first releasing. For Hono, it should be as simple as writing a few lines of code:
A little Mac app that syncs markdown tasks to Apple Reminders.
Initially I released it for obsidian: https://news.ycombinator.com/item?id=39764919 but realised it works with just markdown so I rebranded the app, added some new features and increased prices.
Obsetico App (named after a friends' comment that "it's great for Obsessed people like my wife"

As a hobby I´m working on my digital logic educational board. In the middle of releasing new product that where you can connect different logic gates together and I have added clock functionality that adds timing to the logic. https://logicgat.es
I’m working on https://www.hessra.net/, an identity + authorization service built around [Biscuits](https://www.biscuitsec.org/) instead of JWTs. The goal is to decompose auth primitives so they’re easier to use in service-to-service cases, while also showing off what Biscuit tokens make possible.
JWTs feel like problems waiting to happen. I think biscuits give stronger guarantees and are harder to get wrong.
One piece I’ve shipped is an identity token that can be delegated offline. For example, “company:alice” can delegate to “company:alice:agent,” and that token can then be used to request an authorization token. This makes for a neat API key model: you can issue a simple opaque identity token to your customer (e.g. “customer123”) without having to maintain a DB of hashes/expirations, since those are encoded into the token. Later, you can upgrade security by exchanging the identity token for an authorization token, or let customers delegate access (e.g. “customer123:marketing”).
I’ve also been experimenting with higher-order authorization flows:
• Service chains: each step in a request’s path (edge → app → DB) can add attestations, so later services can validate the full chain.
• Multi-party authorization: requiring two independent services/orgs to co-sign an authorization token, useful for cross-org or on-prem deployments.
Right now I’m building an OAuth 2.1 profile where the identity token replaces a refresh token and the authorization token stands in for the access token. I’m especially interested in hearing where people find OAuth clunky in practice, or stories from folks who’ve built auth systems with other token types (macaroons, biscuits, etc.) or for use cases where OAuth didn’t fit well.
Biscuits are in the same family as macaroons in that they are bearer tokens that can be attenuated offline, but they go further. A biscuit carries a chain of signed “blocks” that can contain facts, rules, and checks in a small Datalog-like logic language. That lets the token itself express richer authorization context, not just restrictions.
Key differences from macaroons:
- Crypto model: Macaroons use HMAC, so every verifier needs the shared secret. Biscuits use public/private keypairs so any verifier with the public key can check validity.
- Expressiveness: Macaroons only add caveats (restrictions). Biscuits can encode facts, rules, and checks, enabling more complex policies to travel with the token. so you can attest and attenuate (and do some other tricky stuff if you want)
- Delegation: Both support attenuation, but biscuits do it with signed blocks that are verifiable and can be chained across services.
So conceptually similar, but biscuits aim to be more decentralized and policy-rich.
A tool to track SEC filings and dividend changes via Discord.
I originally built this for myself to track my investments, and decided to turn it into a product. I’m planning to add more functionality to support investment research.
I'm toying around with a language that's like Python but with Hindley-Miller interference and some functional stuff. It's not a superset or anything, because I can't do that, but it's interesting how well HM (plus some well-encapsulated escape hatches) map onto the Python ecosystem with all its dynamism.
A burnout detector for SREs. The goal is to help teams identify incident responders who may be overworked/getting burned out.
We are looking at:
-Objective data: signals from incident management tools (Rootly/PagerDuty), GitHub, and Slack
-Self-reported data: asking the engineers how they feel via short survey
From this, we generate a CBI score (Copenhagen Burnout Inventory). We're still in beta, but we've received positive feedback from our beta testers, especially from manager of large and distributed orgs.
It uses Go & SQLite, the nice thing is that the DB is readonly and baked into the deployed container. I use cron on my home PC to do the scraping, update the DB and deploy a new version of the site using Kamal
Emilia, a personal relationship manager. Every once in a while I meet extended family (wives of cousins or their children) or I meet a fellow soccer parent and I forget their names, or who's related to who.
I've used Monica HQ to keep track of this but thought I could tackle differently using AI. With AI you could ask questions like "who's everybody on my aunt's side? Like cousins and their family" and get a good answer.
Afaik other "relationship managers" out there are professionally oriented, for sales people. A lot of them talk about LinkedIn integration, for example.
Take a look at http://emilia-workers-website.inerte.workers.dev/ and if you're interested in Alpha testing, send me an email at inerte@gmail.com - I setup a Discord last week so early adopters can chat with me about.
For the last year and a half, maybe 2 years, i've been working on a 2-man project with my brother. We're trying to make an AI marketing tool that hopefully isn't complete slop: https://www.img-pt.com/
About 2 years ago we were trying to get a marketing agency off the ground. For context, Dall-E 3 was brand new and the AI hype was just starting. We thought, why not try making ads with it? It obviously went terrible. Those old models are junk now, but the idea was there, and we just kept at it.
A big part of the journey has just been getting constantly outrunned by new tech. Just when we'd get close to a decent workflow, a better LLM or image gen model would pop up and we'd be playing catch-up.
We've managed to somewhat keep up and are now focused on image ad gen. what we're working on now is video ads. Not the usual UGC-style stuff other startups are doing, but a more cinematic, polished style of ad. i've seen these made manually on IG, but haven't seen anyone automating it. We'll probably try to ship this in a week or two.
We're also working on a campaign management thing that can take a meta ads campaign, spit it into ad sets for the funnel, and create the right ads for each. it'll also be able to shift budget to the ads that work and swap out the ones that don't, all automatically in your meta account. that'll probably be rolled out in 3 weeks, fingers crossed.
We'd be glad if you could test it out and give us some feedback. i'm mainly interested in whether the ads are actually usable in a real-life campaign. A lot of the ad-gen tools i've seen feel like a nice proof of concept, but they're a bit sloppy and not something you'd actually use. i'd be very glad to know if you find it practical.
I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts, GitOps style and I think it's really starting to hit its stride. I just released a new version yesterday: https://github.com/stryan/materia/releases/tag/v0.3.0 .
There's been a couple attempts in this space before but they usually seem to peter out after a while. I'm hoping to avoid that by staying flexible and focusing on just managing files instead of creating a new compose-like DSL. But even if it doesn't become popular I'm just happy I don't have to manage my homelab with Ansible anymore :) .
I have a friend who is having twins. I'm using some new woodworking techniques to make a pair of baby rattles for her. The real challenge is trying to make two shapes with organic curves and precise cuts that are as close to identical or mirror-image as possible, while also hiding the joints.
It's very low-tech. No screens, no CNC, the most technically advanced tool is the digital RPM readout on the lathe. It's nice to disconnect from my screens once in a while.
We're building Doctly.ai - PDF Extraction with AI.
We started out with document conversions to Markdown but quickly realized that most use cases were for JSON conversion. We recently launched our "Extractor Studio" where you can have AI analyze a few sample variations of your documents and come up with a schema for you and publish it to an API endpoint.
We've built a technique on top of AI models that dramatically improves run to run consistency of JSON output.
I tried doing this years ago as a stand-alone project and it was too much. I wrote a data diff/patch/merge tool called "daff" that worked okay. But I've always wanted to add this to a proper spreadsheet tool like Grist.
I really want people working on data projects to be able to work more like coders, with pull requests and reviews. Not all data projects are as curated as that, sometimes your data is just a big soup, but when it is curated, there should be a better workflow.
I am working on a tiny cli project, tascli: https://github.com/Aperocky/tascli, a local fast and simple personal task and record manager. Specifically, I need to update it to support recurring task and records.
I’ve been working on an app called Lång. A daily spending guide. It shows you what’s okay to spend based on how much needs to last how long.
For over a decade, I’ve thought about how most people seem to resist the advice about money. And also how all advice is based on the same idea: seeing where your money went and making monthly plans based on that.
I think people feel that this is a poor match for how money works. So they improvise. And because we tend to not discuss money with others, they improvise on their own. What this typically looks like is checking their balance and trying to pace things.
I’ve been trying to design the app around that. Providing support to what seems like a natural, instinctive approach to managing money.
I've been wanting to build something like this for myself, but partnering/integrating with banks seems to be the main difficulty. How do you solve this?
And which cards / banks does it support?
Also, what does the name mean? It might be a tad difficult to google, unfortunately, since I imagine that googling "lang" would come up with a lot of other results.
It doesn’t integrate with banks. You log as you spend. It’s a common question, but I think there are many reasons to keep it manual. It keeps you aware of what you have left. And automation won’t ever be perfect, so you must keep an eye on it and adjust things.
The app focuses just on your everyday spending. You don’t log bills and subscriptions. And it’s not about being exact. You can add the rough total of what you spent. It acknowledges that when you plan your spending, it’s really just a guess. And you’ll adjust the plan as you go.
What did you have in mind when you thought about building something like this?
The name means ’long’, and is pronounced similarly. Naming is of course hard. I’m hoping that it will be something you remember.
I've been working on Outcrop full-time for a few months now, since I left my job at Stripe. I think knowledge base systems are some of the most important components for successful companies. Current tools are too slow and too messy. Many companies end up developing a custom internal wiki to supplement their Confluence one.
Outcrop is powered by custom search, collaboration, and authorisation engines. Everything is indexed, including comments. Search and navigation are instant. I have a long list of itches I want to scratch with this product. I'm doing a round of private previews to collect feedback, if you're interested, please sign up, I'd love to talk you!
I am working on a tool for testing web apps with a simple to use syntax/DSL aimed to reduce work for automated testing of applications, based on Playwright (Go).
It has additional cool feature like documentation generation in which the steps of the UI test can be used to generate a markdown document with screenshots to aid teams in crafting end-user documentation.
I am planning on adding reports like Playwright and Cypress support and then later on adding support for running tests on remote browser instances to enable different workflows
I'm writing a minimal, educational WireGuard implementation to practice networking and cryptography: https://github.com/drio/miniwg. It's still in heavy development, but it's been a great learning experience. I've already been able to create tunnels between two miniwg instances and between miniwg and Jason's WireGuard from the Linux kernel.
Before that I wrote: https://github.com/drio/unboxing, a c/webassembly implementation of Danielle Navarro's beautiful IFS fractals.
The goals is to become THE Gantt chart add-on for anything. Currently works with Todoist, Basecamp and Trello. I’m struggling to find more markets.
It’s basically “Turn X into an editable timeline with syncing capabilities and dependencies”
Open to suggestions and ideas how I can make this take off.
I’m currently in the process of consolidating every integration into a single account. Previously (currently) it was “Ganttify for Trello” or “Ganttify for Basecamp”. It will become “Ganttify, connect one or more integrations to your liking”.
That might help simplify things for users I suppose.
I’m solo-coding the clear commercial project smmdealfinder.com which is not ground-breaking or amazing as these other great projects here, but its been an amazing journey for me personally for the last 18 months and has developed me probably from a junior engineer to senior+/staff.
Whilst I’m recently really critical of most AI posts here, this wouldn’t have been possible without AI, but mainly because AI could feed my curiosity and barely any riddle was unsolvable, when I put it into pieces and combined it with debugging (and checking docs). Actually most riddles on my level weren’t unsolvable before, but AI reduced the friction and speed of learning for me. This actually goes beyond coding. In life I just ask and learn a lot about, washing, cooking and domain-specific terms.
I'm building a mindfulness app to help people set daily intentions and practice gratitude — https://www.justfortoday.app/
It’s a free app called Just for Today, inspired by a poem I found in the book How to Stop Worrying and Start Living (amazing book).
- It’s completely free;
- No ads;
- No account;
- All offline - Everything stays on your device;
The poem is a gentle reminder:
- You don’t need to fix everything today;
- You just need to be present — Just for Today;
That simple idea became the heart of the app.
Each morning, the app invites you to:
- Set a kind intention;
- Check in with how you’re feeling;
- Practice gratitude;
- Write a little — just for you;
I'm trying to get my agentic software specification tool Arbiter to release (UI polish/debugging is so slow :/, browser shenanigans are harder than Rust fr). It's basically a tool that AI agents can use to construct a project specification. The twist to Arbiter is that the specs are structured and validated, and you can compile them to get:
Services with stubbed endpoints,
UIs with placeholder components,
Dockerfiles/Terraform/K8s infra,
E2E tests (via declared flows),
Github/Gitlab epics/issues/subissues
It's also got github/gitlab webhook integration, so you can do stuff like trigger agents reactively when events occur on a repo, it includes cloudflare tunnel support so you can set up webhooks even in a local dev environment, and the project generator is fully customizable.
Nope, it's a structured spec agents construct using a CLI or MCP (you can also interact with the spec using a web UI). It's CUE, and validated against a schema. Instead of taking your conversation and generating a markdown document that agents might (but often don't) respect, the agent populates the spec in the service from your conversation, then when you're done you can use the CLI to automatically generate a bunch of code.
I read a paper called "The Rise of Subagents" by Phil Schmid at https://www.philschmid.de/the-rise-of-subagents and thought it was an incredibly powerful architectural pattern for running AI agents with complex tasks.
So, I decided to build a practical implementation of this system with a central Orchestrator that manages a fleet of implicit or explicit Subagents. Each subagent is a specialized, isolated AI agent designed to perform a specific subtask. More details in the repo README at https://github.com/skanga/conductor
I have a steep pitch (1:1) roof, and I'm building ladders so I can get on top of it for cleaning, etc. I actually did this a decade ago out of wood, but it apparently hadn't been inspected / seasoned / treated correctly (by the people who produced the lumber) and after a couple of years the thing started growing mushrooms so I had to tear it all out. Just re-roofed a month ago. Building it this time out of mild steel. Cutting, drilling, bending, welding... oh my! Plus there's the risky business of assembling it in place on aforesaid slope.
If I don't have a consulting gig where risk is taken seriously, I can always work on my house or my motorcycles. :-p
I'm working on ScaleDown [1], a context pruning API.
So over the past few years, I have seen how contexts have been steadily growing in AI apps. And while the context lengths of LLMs have also been increasing, they are still effectively about 200k tokens. The performance drops off a cliff after that (you might have noticed it as well with long AI chats).
It is a simple API that prunes away irrelevant parts of a context for a given prompt, a.k.a. context-aware pruning. Integration is super simple: just an extra API call before the final LLM API call. You can get an API from the website.
I would love to chat if this is something that is relevant to you and if you have any feedback on what we are building!
I'm working on a WordPress PaaS with dedicated lanes for bots. The status quo around WordPress is that you block bots using Cloudflare, else your site crashes. Since AI search is here to stay, we need a way to let bots crawl WordPress sites without crashing the server.
I am working on a answer engine for Hindu Scriptures and old Sanskrit works. I already have a corpus of all the documents which are indexed and currently working on a LLM based answer engine that focuses on answering questions from Vedas and Upanishads and Mahabharata (for ex). Think perplexity but completely focused on Sanskrit sources with proper quotations from the exact verses where the answers are found.
Planning to release this into the wild for people to use. I currently am struggling on how to fund this properly as the server costs are going to be huge for such an effort (search engine + LLM).
I've been working on 'Fragno', a TypeScript framework to build full-stack libraries with. It allows the library author to define backend routes, and provides them with reactive primitives for building frontend logic using these routes. This all embeds into the user's application. Eventually, it should include a data layer as well.
The ideas are in large part inspired by Better-Auth, which is built on top of similar primitives. I hope more libraries will be built in this manner, because I believe that it provides very nice DX for the integrator/end-user.
It's not quite ready yet, but I did write most of the documentation.
I'm working on a video platform called Nickel. 5-second clips and 5-minute (max) videos. I've been slacking on development but realized recently that I lack focus and am easily distracted by other projects. I wrote about this yesterday.
I did figure out something I've long wondered about recently. Y'know how you can see previews of videos in Messages? I got it working! Here's an example video: https://nickel.video/6NI3n_IlIlII
My inspiration for Nickel was 1) missing Vine and 2) not wanting to use YouTube to share my gaming clips.
I'm working on https://X11.Social, a voice-first content creation tool for X.
The initial idea was "call to tweet", the ability to compose posts on the go by having a natural conversation with an AI assistant over a simple phone call. This is useful for turning thoughts from a walk or drive into a polished "brain dump" post, or for engaging with user lists without being at a computer.
It has since evolved into a broader system:
Chrome Extension: A context-aware assistant that lives in the browser. It has a Quake-style console (activated by opt+space) for quick chat and can analyze the content of any page you're on (e.g., YouTube transcripts, articles, other tweets) to help you create relevant content.
Engagement Predictor: A feature that scores tweet drafts in real-time to predict their potential for engagement. It's built on a model trained on my own dataset pulled from the X API and other public dataset from Kaggle[0].
Scheduled AI Calls: The system can call you on a predefined schedule to proactively brainstorm content ideas.
Here is the tech stack:
- Frontend: React, Tailwind, shadcn/ui
- Auth: X OAuth
- Payments: Stripe Subscriptions
- Voice AI: ElevenLabs Conversational AI, Twilio
- Engagement Predictor ML: Python, scikit-learn, XGBoost on a data pipeline from X API v2 and a base dataset from Kaggle.
- Chrome Extension: Same as Frontend and Chrome Extensions API
- Blog: Jekyll
- Infrastructure: Deployed on AWS Fargate using AWS Copilot for orchestration (ECS).
I'm building solo and just got the first trial user after 87 days of building in public. It's a long road but the feedback so far is encouraging.
I’m working on a new vision-language model architecture called Onida. Our aim is to match—or surpass—the performance of leading VLMs like LLavA and CogVLM, while operating at a fraction of the cost. Unlike most existing VLMs, which layer vision components onto a language model as an afterthought, Onida is designed from first principles with a truly integrated approach.
This document [1] outlines our key differentiators, and we’re now inviting beta participants to explore and test the technology.
A side project that takes legal documents and uses TTS models to create a narrated read out of the whole document.
Part of the reason I'm building my own solution is that legal documents are often distributed in PDFs which can have all kinds of formatting issues when converted to plain text. There's also specific jargon and formatting that may or may not need to be included, or spoken, or even spoken differently, that I am finding no commercial TTS platform like ElevenLabs really accounts for well. It's all about the pre-processing and chunking.
Also, the commercial models are expensive when you're routinely throwing dozens of pages of text at it.
I've been working on three micro-saas, all built in Elixir/Phoenix:
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.
https://rizz.farm - a lead gen tool for Reddit that focuses on helping instead of selling, to build long-lasting organic traffic.
https://persumi.com - a blogging platform that turns articles into audio, and to showcase your different interests or "personas".
I'm working on a notes app that is as simple as Apple notes, but has native markdown support and uses semantic search.
Uses SwiftUI for the UI, and Zig does most of the heavy lifting on the backend. It's inspired by ghostty which uses a similar setup[1].
Right now it only works for Mac, but I'll be porting to iOS as soon as I get the markdown renderer polished. It's not available to the public yet, but I'm using it as my daily driver and hope to release it later this year. I've open sourced it so you can see the source code here[2].
I have 2, not yet sure where to focus on so both for now
https://YouGotPicked.com - A simple list picker tool (for when you can't decide between options)
https://Drop.Top - A lightweight emoji-based feedback widget in minutes, so real users can drop contextual bugs, suggestions & ratings — all tied to session replays. See trends, sentiment & hotspots in real time, then feed feedback straight into your Jira/Slack/analytics stack.
Building an app to help me stay in touch with my friends (https://wavepal.app).
I have ADHD and often forget to reach out to important people in my life, not because I don’t care but because “out of sight, out of mind” is EXTREMELY true for my brain.
I started building Wavepal with a friend earlier this year so I can track when I last chatted with people, what we talked about, important details that I’m likely to forget (kids names, important dates), and it auto sends me reminders when enough time has passed since we last talked.
I'm working on exploring an exploit in physical security systems that I haven't seen anyone investigate before (at least, not published on the internet). It's involved an interesting combination of reverse engineering, pentesting and regular prototyping/hardware development.
Currently writing a run-through of it to publish on my website. I'm not sure how secretive to be - I think I just want to be the first to actually release my findings. In my post I'll detail the steps to reproduce my results so more people can look into this.
So far I haven't found any critical ways to (ab)use this access control system weakness, as it only typically applies to the outer layer of physical security.
I am working on the MVP for https://www.thelabcompany.co/ the professional network for Upskilling. Solo founder. Experimented with asking LLM for a skill graph of AI skills from git. That went nowhere. Now looking to do something simpler - RAG + memory of user feedback to guide the user on fun projects to build that also include cutting edge skills.
Would anyone want to build skills just for the joy of building? Is everyone who signed up wanting only a job? will leave the network as soon as they land a job? what would you do?
I'm working on a site for filmmakers to help showcase themselves!
Why? >
LinkedIn isn't for creatives.
Actor's Access is dated and charges a ton for basic extras
Squarespace/wix is fine but everyone in 'the biz' has one and nobody wants to maintain it. Plus they're all silo'd.
Check out my site if you wanna. You get to host your own headshots, resume, and reels. You can upload your screenplay there and hear it read outloud. You can put up your cinematic scores and make a place to send people to hear your music.
Currently it's meant to help devs fix UI and UX issues by seeing exactly what their users saw, including a log of the browser console and network traffic.
I say currently because it has preset analytics (charts for top entry page, top exit page, etc) but am working on letting users define their own trend and funnel charts. That will open it up to basic web/product analytics.
The goal is to be simple analytics + session recording w/ masking.
Been exploring the amazing GCAT space dataset - it’s been a good way to drive some dashboard feature experimentation using fun data. Still need to work on my dashboard design skills, though.
Building https://pneumatter.com to explore embodying articles of Programmable Architecture (self-assembling buildings)which are weather-compliant, resource generating, and optionally permanent.
It gives you precise control over every shade/tint (no AI or auto generation!) so you can incorporate your own brand colors, and helps you build palettes that have simple to follow color contrast guarantees by design e.g. all grade 600 colors have 4.5:1 WCAG contrast (for body text) against all grade 50 colors, such as red-600 vs gray-50, or green-600 vs gray-50. There's export options for plain CSS, Tailwind, Figma, and Adobe.
I'm really open to feedback on what problems and needs people have for creating accessible designs!
I'm working on spaced-repetition language flashcards app, that shows you variety of card types (sentences, reverse, audio, definition...) and allows you to add vocabulary from content - youtube, ebooks, website reader.
What’s baseless about it? The yearly subscription price is like 20 minutes of work for programmers and many users are spending tens of hours on the app.
A (so far) simple AI assistant to provide help if you're moving with your pets to a different country. I've got a vector db with some US travel documents embedded, parse the question/prompt, and add the relevant context to a standard LLM request.
It also parses the question/prompt and stores move and pet details, so later questions will have context.
Eventually, the idea is to have a full tracker and reminder system... so deadlines, appointments, and documentation can be stored and referenced in a single place.
I’m working on Colanode, which is built to close the gap between the convenience of cloud tools and the ownership of local software. It brings chat, docs, databases, and files into one open-source, self-hostable workspace where data lives on your devices first and syncs in the background. Unlike typical SaaS tools, Colanode is local-first: everything works instantly and offline, infrastructure stays minimal, and you keep full control of your data.
Hobby. Very rudimentary, not everything working yet.
Think ansible for your user account (except it will definitely not be ansible for your user account).
Whenever I have a new machine, I do the same steps over and over again:
- Installing some packages (like make)
- Setting up an ssh key
- Cloning some git repositories
- Setting up dotfiles
- Installing rustup / rust
- …
Until recently I tried doing all of that with a bunch of bash-scripts, but that turned out to be messy and not a joy to maintain. So now tried a slightly different angle with a rust tool that you can just pull out of the CI, no dependencies, and it will setup everything (for me).
https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a proper accounting foundation.
It's a double-entry personal finance tool where you own your data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Soon with multi-currency support. Currently targeted for desktops.
It's interesting in many way. Using double-entry (it's a perspective shift and a power tool), the challenges and advantages of building local-first app, UI/UX & visualizations, privacy and more. For personal apps, local-first is a good fit.
I still am not sure exactly how to define it, but it's a ruby library, that is mix of a rules engine+spreadsheet feelings+array language+static validation+compiled/codegen... that last part is mostly not merged yet but yeah, ruby DSL codegenerating ruby, it's ruby all the way.
https://github.com/amuta/kumi/tree/codegen-v5
(see ./golden for more context on the compilation/codegen. I barely knew what a compiler was before doing this so I might have just created some nonsense )
I'm building with python/fastapi, react/tailwind/vite, with Claude Code and using test-driven development.
Red-green-refactor is tedious for humans but perfect for AI. And the test names & code make great documentation of every micro decision, running in milliseconds to prevent regressions.
The software itself helps people perform construction approvals.
Old way: dozens of documents and versions sent back and forth over email. Many fiddly details that must be checked - to streamline the process we'll use AI to provide verdicts that help humans make decisions.
I plan to create content & teach what I've learned.
I am all-in on a Unity game right now. Working with one other person and hoping to ship to Steam later this year.
Thinking about play testing at scale is a new thing for me. I've been getting into visualization techniques like using 3d textures to build voxel heat maps in-editor. We've managed to accumulate quite a bit of play testing telemetry already. The power of aggregated statistics in the editor views is absolutely mind-blowing to me. For level designers it's like having proper omniscience. Being able to see things like thousands of samples (manifesting as a bright red voxel) that wound up tripping over the same misplaced geometry is like cheating.
I'm working to build a tool for macOS and Windows desktops to help non-technical users figure out what's wrong with their home internet and how to fix it. https://www.networkweather.com/
It's literally just me in the garage right now banging out prototypes, talking to MSPs, and probing networks/WiFi/OS to make this tool.
The hope is that companies care whether employees are productive when remote/hybrid/on-the-road, or at least are sick of trying to triage first line helpdesk tickets about home network issues and Zoom glitches.
Like the rest of online mass media, HN covers generative AI a lot but there is still plenty of value in predictive AI. Both forms provide plenty of technical challenges to the AI engineer. I miss the days when you could get a stack trace to when debugging an issue.
Trying to document my current hobby project, but stuck in the analysis phase. I dont even know what it is. When I try to describe its purpose I get blank looks. People tend to need physical demonstrations to understand whats going on. Its not entirely new, or novel, its definitely not revolutionary, but it is a hybrid of so many things, in a very indirect sense, that its just beyond my verbiage. Not a humble brag, I dont think its amazing or anything. I have just failed to describe it. Have been trying to get a phd I know to look at it, and describe it for me, but he just straight up isnt interested.
I worked on Dockside last year (https://hachipoo.com/dockside-app) — a small macOS app that makes use of the unused space around the Dock (especially nice on widescreens). It’s non-intrusive and lets you drag & drop files, jot quick notes, or add shortcuts right beside the Dock so they’re always handy without cluttering the desktop.
Right now I’m adding few of the most requested user-requested features (vertical Dock support etc.) and working on refining it for Tahoe release.
Banker (banker.so): An AI spreadsheet that excels at spreadsheet understanding (pun intended).
There are some AI spreadsheet products out there mostly as plugins along with MS Copilot. However my experience with them showed that they are bad at understanding spreadsheets.
The reason is that sheets are 2D data models. Because LLMs are trained on 1D data models (simply text), translation of 2D data models to formats an LLM can consume is a big context engineering task.
I read and implemented some of the algos mentioned in SpreadsheetLLM paper released by Microsoft. Ironic, isn't it?
Got it to a nice working state. Give it a go - if you need more tokens, let me know!
I just started uni, so mostly that. I've found myself making a little CLI for the timetable website and using a software defined radio so I can hear the lecturer while still having noise cancelling.
MAXSTACK: Web framework for rapidly building SaaS apps with AI - trying to enable the next wave of 'fast-fashion saas'. Think of it like better-auth is doing for auth, I want to do for the rest of SaaS
- comes with common SaaS features pre-built (crud, blog, auth, etc.)
- import templates from the framework until you want to customize them
- create forms with just a zod schema
- good docs, typescript interfaces, a CLI for common tasks, and MCP for your AI agent
If you're building something now or want to - I'd love to help. Could use the experience to make things easier through my framework.
- A super easy-to-install monitoring tool that doesn’t require bash scripts or config files
- A mobile-friendly, UX-first interface where I can check everything from my phone
It’s now pretty feature complete. I can see a full picture of all the servers and VPS I run straight from my phone.
Setup is one command, no config files, and everything else happens in the UI. There’s a catalog of predefined alert rules, and creating new ones is easier than anything else I’ve used.
That’s not actually a bug (maybe the message need to be more verbose). The agent is running, but it doesn’t yet know what data to collect. You’ll need to finish the setup in the UI by choosing what metrics/logs you want. Once you do that, the error will go away and the agent will start collecting data
Ah thats what I get for not readin! It's working perfectly! The only thing missing for me is ingesting the logs for my service directly from journalctl, that would be amazing
SQLv2 is a next-generation standard that unifies traditional SQL, machine learning, vector search, generative AI, and multimedia support into a single, cohesive query language.
Long nights and weekends to, but is all well worth it.
Yep, you read it right. 0 false positives. We scan the whole codebase for possible vulnerabilities, rank them, write the proof-of-concept for exploitation, spin up the software in a sandbox, and then attack. All of them happen autonomously without human involvement.
The end report? Only verified vulnerabilities are being reported without noise.
Already reported some unknown vulnerabilities in open source projects. The good thing is we're just getting started.
i've been incrementally hiking the via francigena (https://www.viefrancigene.org/en/walking/) and am working through integrating my gpx, geotagged photos, and oura ring data to both illustrate my journey and analyze how different terrains and altitudes affected the collected biometrics.
ingesting/parsing gpx layers into duckdb using python to extract tags and load api data. using minio right now but ultimately want to push to cloudflare free tools or vercel.
I'm working on a product to break down information siloes for private market investors. A lot of data for private equity, private credit, and venture capital firms lives in memos, deal books, conversation notes, emails, and chats. In some cases, attempts to organize that data in a more structured format (e.g. using the CRM) has resulted in data not getting recorded because of the friction of managing those types of systems.
So basically, I'm building a system where users can query all of that unstructured data and add more with a little less friction.
Shared memory for AI coding agents. Every agent currently reinvents the wheel - your agent debugs a Stripe webhook signature issue that mine solved yesterday, burns tokens doing it.
Building the retrieval and memory maintenance layer. Interesting problems around decomposing solutions into reusable patterns, ranking/deduping at scale, keeping latency under 100ms. Uses MCP so it works across IDEs.
Early benchmarks look promising. https://memco.ai if you want to try it.
I'm working on a tool to do evals for voice agents. The way it works is that you simply post your recordings, tools, instructions, etc and we do a diff to spot if something changes, then we mark a note on the change and run evals.
The main idea is that you don't need to configure anything, simply send us the data and we should figure out evals for you.
If anyone is building with realtime voice send me an email at username at Gmail and I'll try to help you improve your tool for free (In exchange I get to talk to real users)
Building https://multi.dev, an AI coding agent with bunch of FOSS contributors
We took a great amount of learning from tools like Cline, Roo.. After spending some time on their tech as active users/devs, we decided to build multi from scratch with drastically different take on core features, tech stack, ux/devex..
If you are an active user of similar tools, and/or want to try multi.. We want to hear from you.
--
edit: I am one of the core contributors to multi. And we are in the process of open sourcing it.
I’ve been using tools like Cline and Roo-Code quite a bit, and the idea of rethinking the core stack/UX from scratch resonates a lot. The agent workflow and devex feel like the hardest problems to get right, so I’m curious how Multi approaches context management and long-running tasks compared to the others. Excited to see it open-sourced and will definitely give it a spin.
> I’ve been using tools like Cline and Roo-Code quite a bit, and the idea of rethinking the core stack/UX from scratch resonates a lot.
Would love to learn more about your experience with cline. We spent quite some trying to add multi agent capabilities and improve the overall ux/devex of Cline (and its clone Roo) to make it more intutive for developers. we found that its stack is not built for these capabilities, and the codebase was not as stable as we would like it to be. it required a major rewrite, at that point being another cline clone made no sense to us.
> The agent workflow and devex feel like the hardest problems to get right
yes, AI coding agents are probably the most complex agents out there. our approach comes from actor model, where each agent manages its own event-loop. we found this is incredible robust way to build specialized agents that interact with one another within multi. Too early to say but
> Excited to see it open-sourced and will definitely give it a spin.
thanks. still brewing but will let you know. appreciate your feedback.
I created a 2D platformer inspired by the classic Mario games. The game is called Jolly Land Adventure and I made it because I wanted a simple platformer that's easy to just pick up and play.
The game is available on Steam for Windows, Mac and Linux. The demo contains the entire first episode with 30 levels for anyone who wants to try it out.
Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them.
Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods.
I'm working on a web app that creates easy-to-understand stories and explainers for the sake of language learning. You can listen in your favourite podcast app, or directly on the website with illustrations.
I've mostly focused on Japanese and French, but I'm eager to add more languages if anyone is able to help me evaluate the text-to-speech for that language.
pptx-tools, a collection of cli tools for interacting with Powerpoint presentations. Covers use cases that PowerPoint doesn't support. Currently in the making:
* pptx-grep - find text across multiple powerpoints, yield file/slide no and text excerpt of match
* pptx-dump - dumps extended info about a powerpoint, such as number of slides, applied master slides, used fonts etc.
* pptx-lint - allows to define validation rules for pptx based on content and/or formatting. E.g. presentation must not contain word "TBD", all text must be formatted in Arial etc.
I joined two current interests, my need to learn better JavaScript (since I never used it much) and the discovery of programs like PICO-8. I realize TIC-80 is basically the same but allows me to use other languages, so I’m trying to write small games using JS. I’m still on the struggle phase, trying to learn how to make sound effects, music etc. but I like the fact it comes with everything you need to create whatever you want. Also like how it makes you forget about all the giant software complexity nowadays.
We are working to build Notion, but for books. It is a personal book diary to collect your to-be-read and smart sort them, as well as log your reads and use that data to build a profile of your book dna in order to connect you with new books/authors that your book twins love.
I've been building an innovative guided munition for Ukraine for the last 4 months, we have first prototypes made and have arrangements with the testing range to begin flying them soon.
It looks like Markdown is having a bit of a heyday with it being the default mode of docs for AI coders. And it became apparent that there is no simple, but powerful Markdown viewer for the Mac, so I made one.
It supports all the usual Markdown formatting but also diagrams and equations so you can get Claude to not only write up your system docs but also supply a diagram of the database structure, logic, or AWS services.
It would be cool if you gave it a go :-) It is in the Mac app store "ViewMD"
After I made a small MMO prototype over at https://everwilds.io/ (open-source) I am now working on a vehicle building prototype at https://evergate.io/, if you're interested in following the progress there's a Discord link at the top right corner of each website. Mainly focused on Evergate right now :))
I've been vibe coding this and that all summer. I'm making a team retro clone for sprint retrospectives, a typeform like form builder and hosting, a Reddit client with AI analysis of trends and a few other things like in various stages of development. LLMs really help me move things forward. I have those first 3 up on vercel now and I'm going to push them to production in a while after I'm satisfied with stability and the like.
It's been really fun writing this from scratch and trying to design a mobile-friendly API that fits the OTel spec. There's still work to do on OTLP export and various other features - if this project interests you, please do get in touch!
Working on a "Data Governance in a Box" solution for small businesses that are using out of data routers and security practices. Starting here in Canada, but open to collaboration.
I'm converting PG's essays into latex. It generates 4 "volumes", each with it's own mobile + PDF. It's still early, but am really happy with it so far!
I've been building bewCloud [1] (a simpler Nextcloud alternative written in TypeScript) over the last couple of years and it's finally reached "feature freeze"; I don't plan to add anything major to it anymore, and will now keep maintaining it, updating it, and will focus on removing dependencies. I'm currently waiting for a security audit.
I’m building https://analytics.robomiri.com, a lightweight, privacy-first analytics tool that gives you real insight without turning your users into tracked profiles. It captures page views, content engagement, funnels, and user paths in a minimal UI.
My goal is to balance usefulness with simplicity: metrics you can act on, not just dashboards to stare at. I’m leaning hard on defaults like anonymization, flexible retention, and user control over what’s collected.
The hardest parts are always the ones you don’t see: scaling storage & query times, making interpretation meaningful (like “this bounce rate is unusually high”), and doing all of this in a way that’s GDPR/CCPA friendly.
Why do this? Because I believe analytics doesn’t need to feel creepy. You should be able to learn about your users respectfully — see what’s working, diagnose what’s broken — without handing over control or trust.
On the side, I‘m building a platform that allows to run MCP servers on demand, making them reachable under a public URL, but password-protected.
You also get an embedded VNC viewer, and thus you can watch what an AI-agent is doing with it.
This makes it possible to use your own, dedicated MCP server instances from, for example, n8n workflows, without thinking about infrastructure.
I've see so many HN posts and cmments about CSVs sucking and Unicode control characters as delimiters, that I set about creating a spec and some tools for use with it.
Nothing good enough to share as its own post, but its something I'm working on that people may be interested in.
Working on an AI/Governance and compliance system that also integrates with the cli for teams developing the actual code and the systems that are commonly used, GitHub, bitbucket, open policy agent, collibra etc..
Used by enterprises for compliance, reporting and answering questions like, who owns this ai model, whats the monitoring plans, where is it running, what approvals does it have, what policies are applicable (geographic etc).
Trying to build a secure, configurable and easy to use authentication system (relative to my understanding)
I have experienced knowledge gaps and blind spots that I am attempting to fix. For example most users worry about security of hashed passwords and yet they do not realize that the TOTP (eg Google Authenticator) use symmetric encryption and quite a lot of the authentication providers store the private key in plain text in their database. List goes on...
Thinking about vibe coding a Behaviour Change App as opposed to a simple habit tracking app. I have personally used the habit tracking apps, and they are absolutely useless. My app will help the users learn how to actually change their behaviour, teaching them micro skills like value alignment, self-compassion, etc. These micro skills will help them in all aspects of their life and mainly to change bad habits.
It annoys me how much a bad trailer can spoil the movie, so I made this platform to rate trailers how "spoily" they are and how good they are. To my surprise, you find some great trailers without many spoilers, but then you will have trailers which are basically a 3-min summary of the movie.
LLM/procedurally-generated fictional wikis with worldbuilding history/context so the wiki stays coherent. Fun project to make the most of LLM hallucinations
I'm vibe coding using GitHub Copilot and JetBrains AI Pro on a Blazor web app that tracks my investment in like index funds, stocks, ETFs, etc. It's a simple CRUD web app.
The app is nearly completed, and Grok (preview in Copilot, currently free) wrote most of the CRUD pages with Entity Framework. Of course, it does get things wrong, and I use Claude 4 to fix the issues. (i'm a C# dev, I review code generated by Grok sometimes.)
Improving my 'Video game generator from photos'.
The bottleneck of this kind of generator is 'how much time to obtain the video game".
I managed on my last vacation (it's a side project) to reduced it to 2 hours.
This is an example of one FPS made by my tool :

I'm working on a new type of git forge[1], optimized for speed and work with patches.
It goes to extreme lengths to ensure great performance, i.e. rewritten most server-side parts of git from scratch, so there is no "exec"-ing git nor calls to libraries like libgit2. The frontend should also be very fast thanks for HTMX.
Building a platform for documenting all of the publicly accessible stained glass (something akin to Find-a-grave.com, but for stained glass). No exciting tech, just vanilla HTMl, CSS, and JS. Glad to have any help on documenting local stained glass in your area!
It's a personal knowledge system. It's a zettelkasten with an LLM substrate. It uses LLMs to build a model of the theses, arguments and facts used in cards, and uses these to both summarize the information on the card and to automatically link cards together based on shared concepts.
Early stage with ARK Cloud API & Stateful LLM sessions without input token costs. Conversation history is kept server-side, so you only send new messages.
Demo and docs: https://ark-labs.cloud/documentation
Looking for feedback on use cases and session controls (machine2machine).
A script which will find random pictures of anyone in the family from the Immich database, resize them and add metadata on them like where they were taken and when and put them on the TV to show as kind of a screen saver when we're at home.
I like this Facebook feature which shows you "Today 10 years ago", Immich, does have it in it's UI too and perhaps I will mix in those pictures also to show on TV.
I’ve created an AI-powered app designed to help candidates prepare for Meta’s product manager interviews, with a focus on product execution questions. The app allows you to practice by speaking or typing your responses, then uses AI to score answers against a rubric and track your progress over time.
I’m looking for beta testers—happy to share early access if you’re interested! If you are please message me.
I am a bit of a checklist nerd, so I wrote a web app do to checklists: https://checkoff.ai
As it is fashionable these days, it can create checklists with AI ("Fun things to do in Pittsburg"), you can create checklists from templates (some stuff you do every day), etc.
I also have an MCP server that allows you to plug it into your favorite LLM.
I'm working on a super-simple budgeting app called https://4keynumbers.com, which is based on Ramit Sethi's Conscious Spending Plan. It currently syncs my expenses from Plaid and cooks it down into a single chart, with only savings, investments, bills/fixed, and "safe to spend" as categories.
I had been unemployed for a year and worked a lot on DiffKeep (https://github.com/DiffKeep/DiffKeep), a cross platform AI generated image management program. Fortunately / unfortunately I got a job and haven't been able to dedicate much time to it lately.
Kind of have been wasting time with Cloudflare workers engine. Trying to build a system that schedules these workers for a lightweight alternative to GitHub actions. If you are interested in WASM feel free to reach out. Looking to connect with other developers working on the WASM space.
I’m at a crossroads with my Speed Cubing Competitions listing app (SCComps.com). It’s an iOS app built in Flutter, has around 250 downloads, and currently generates no revenue. I'm spending about $500 a year just to keep it running. There’s little community engagement, and I'm debating whether to double down and rebuild it in Swift—or just shut it down altogether.
Deterministic guarantees, and corrective behavioral monitoring for ai agents (starting with claude code, and ADK). Think security + performance bumper rails. At the cost of 0 context.
I was the feature requestor for Claude Code Hooks - and have been involved in ai governance for quite awhile, this is an idea I'm excited about.
Ping below if you want to early beta test. everything is open source, no signups.
It is a DNS service for AWS EC2 to keep the ever changing IPs when you cannot use the Elastic IP like ASG or when you don't want to install any third party clients to your instances.
It fetches the IPs regularly via AWS API and assign them to fixed subdomains.
Currently I've been working on https://terragonlabs.com which is a way to orchestrate Claude Code and other agents (Amp, Codex) as background agents.
I feel like I am locally constantly bouncing between different agents for different tasks and really wanted to be able to do the same in a remote environment.
I'm working on a text-based softball league simulator where you forcibly enlist your friends and family to join your co-ed softball team. You play as their manager/coach/fellow player.
Every aspect of the games are narrated in real time so you know what's going on. I'm still in the prototype stage and I've seen some pretty hilarious interactions already.
I don’t know if this is really necessary, but I created it after doing an in-house CTF challenge, with no LLM rules, and I was giving several LLM CLI’s a lot of leeway and iterating very quickly.
I'm working on Happy Coder, an open source Codex and Claude Code native mobile app (plus a web app).
Happy lets you spawn and control multiple Codex/Claude Code sessions in parallel. Happy Coder runs on your hardware, works from your phone and desktop, costs nothing, End to End encrypted, and permissive MIT License.
Happy Coder is a unix style "do one thing well" project.
The goal is zero workflow disruption. I want to be able to run CLI coding agents on any internet connected computer, and control them with my phone. Happy has a command line wrapper for Codex and Claude Code that let you start a session in your terminal, and then continue it from your phone with real time sync. So type in your terminal and see it on the phone, type into your phone and see it in your terminal. So you can switch back and forth.
There is an optional voice agent some contributors have been hacking on that lets you talk to the voice agent first, and the voice agent then writes prompts for Codex/Claude Code and answers questions about what the coding agent running on your computer is doing/did. The voice agent feature is pretty neat, but in my opinion needs a bit more iteration, so any ideas or help would be awesome.
A research project on converting a python application from loops to numpy vectorization to jax and pytorch compilation (the latter is fast!). I'm exploring the performance portability of such frameworks across different devices and backends (also gpu). I have also C++ hand optimized implementations that so far are unbeaten
I'm working on learning to sightread on bass, and wanted to gamify it.
Unfortunately rocksmith doesn't seem to have a sheet music view, so I'm trying to write something that will take the input from my audio interface and put it through a note detection library (and then compare to a midi for an accuracy score) to make my own version.
We are building an operating system for making sustainability compliance trivial. Currently we are using a combination of modern AI agents and traditional methods. If you are a hyperscaler or in a heavy industry or just need support for dealing with e.g. California's SB 253 and SB 261, shoot me a message.
I put together a mindless game over the weekend. I haven’t added instructions or optimized it for mobile yet, and may never due to laziness. Click the empty board to make it match the pattern:
I’m building an ETL tool that “just works” and gets out of the way. I can write shell scripts and python to do this stuff but honestly I just want to drop my files/API results into a GUI tool and have it combine things for me. Landing page is at https://eetle.com
I'm working on something that proves to be more ambitious than initially thought:
pure Python notebooks + zero-emission GPUs + git = https://lab.enverge.ai
Currently struggling with an experiment where DeepSeek-R1 is being overly verbose.
I just shipped 3pio, a drop-in test runner that context-optimizes your test output. It uses your existing test runner and tests so zero changes to your codebase or tooling to use it.
IME it results in much less context clutter from your test output.
I love the idea of a free and a distributed/decentralized social media, I have just been trying to come up with some basic arch for it. This is not the final direction I want to go with this, can pivot based on interests.
i am open if anyone is interested in joining!
I'm working a coding agent, named VT Code. It is a Rust-based terminal coding agent with semantic code understanding powered by tree-sitter and ast-grep, and fully configurable and open-source.
Building Bloomberry - an alternative to Builtwith. While the latter focuses on frontend tech, I cover almost every SaaS product category. Want to know companies that use Microsoft Dynamics or Zoom? You can with Bloomberry, but not with Builtwith.
I'm working on a new CAPTCHA designed to be very simple and user-friendly for humans, while maintaining strong LLM bot protection. I'm currently looking for pilot users (content creators, site owners, or anyone interested) to test it out and provide feedback. If you're interested, please comment.
I've been building an LLM powered map for the last 6 months. I'm working to reinvent how mapping applications interact with geocoders and routing engines to make much more powerful and easy to use map applications!
I'm working on character.ai for learning Chinese, you chat with characters at your level, and get instant feedback on your writing. It's a way to get a wide amount of comprehensible input in an engaging way that also practices output.
This is really cool, I'm interested in this as I'm also a chinese learner and I thought about doing sometihng kinda similar (just locally)
I like the UI, really cool project.
I think the prompting might need more work to make it natural though. I just tried a "hungover chat with 996" worker, and the responses seemed to be lacking a little too much context
I am creating a webapp to let screenwriters collaborate when writing their scripts.
I have several friends in this industry and their tooling is either expensive, not localized for their market or straight away bad (I've seen terrible dataloss).
I got some inspiration from linear and am building it on top of ruby on rails with CRDTs.
Scriptwriting require specific formatting (set by Hollywood ages ago). Doing this in google docs is really painful. Besides that, people who work in this industry are already used to the format, so if you wanna pitch something to studios, they expect to be in industry format.
Picshift.io: upload an image, get a URL, change what shows at that URL whenever you want. Works anywhere an image link works.
You can randomize and schedule images to show up at the link as well. Super useful for marketing, maintaining screenshots on a website or in documentation, etc.
Building AI workbench and tools for Home Service Business verticals. I found there is a lot of waste in targeting and workflows for business, focussing on improving them with advanced YOLO and LLM models.
I'm working on Matry - it's a tool for designing in the browser. It's kind of like a cross between Webflow, Vim, Storybook, and Cursor. I'm trying to strike a fine balance that I don't see in existing tools.
Nothing to demo yet, but hopefully I'll have something soon.
Business Name Generator
Generate memorable, brandable business names using advanced AI technology. Get domain availability and social media username checks instantly.
Oar, a GitOps Continuous Delivery tool for Docker Compose. Think ArgoCD, but you don't need or want all that Kubernetes complexity.
https://github.com/oar-cd/oar
Working on an AI-optimized query language. Like a terse, logical SQL. So smaller models can translate natural languages to DB queries more accurately. Saves lots of compute in RAG.
Gradually working on a factory management system framework, built on top of django, to allow for the rapid conversion of a workflow (with measurements required, equipment used, SPC charts, etc.) into something that can be used on a factory floor.
It focused on critical thinking and communication skills by having dialogues about recent news and announcements at the companies you want to work at. Have a 2 min dialogue and get feedback about how you think and speak.
Very close to releasing V3 of my Obsidian template vault with huge improvements, first class AI support, included Bases, a solid productivity system, and a ton more.
i’m working on instantrows, basically trying to kill the pain of dealing with csv/json/excel/parquet exports when all you really want is to join them together, do some quick aggregations, and share the result without begging a data engineer or spinning up a whole warehouse. excel breaks, bi tools are overkill, emailing final_v2.csv is a nightmare. the idea is a browser based, no download tool where you drop files in, it just works, and you get a live link you can send around. curious if anyone else here runs into this every week and what hacks you use today.
Control swarms of drones with an easy sdk. Building open source drone swarm software, for use cases like drone laser tag, farm monitoring, security etc. https://tensorfleet.net
Inspired by a friend getting a random email and it sparking a memory for me: https://pageday.org, a global message lottery where each day a random message is drawn to be the homepage.
Yeah that's a good question, and something we haven't codified.
Odds are that we'll curate quite heavily to keep it interesting and maybe along similar guidelines to hn with "anything that gratifies one's intellectual curiosity" rather than just "anything".
A way for people to build LLM-powered webapps and then easily earn as they are used: I use OpenAI API and charge 2x for tokens so that webapp builders can earn on the margin:
Im building a Calendar API. After working on a .Net Framework application for a long time, I finally started a .Net Core side project. Holidays, recurring events, timezone support, this thing should keep me busy for quite a while....
Writing a book intended for nontechnical people using LLMs cautioning them against certain common recurring issues. The idea came to me when I saw some of the outputs across various fora that were a little too common.
Super interesting. I'm a behavioral scientist, and I spent a ton of time thinking about AI adoption patterns and how certain experiences can be a massive detriment/boon to adoption. Let me know if you'd be up for a chat!
Writing a specification for a personal library app in the hopes I can get AppSheet + Gemini to make one for me. I'm working on library science in general, so it will hopefully implement ideas I have about book classification and entity catalogs.
I’m building a database which is optimised for local storage and Orleans clustering, the idea is that leveraging a bare metal perspective and access patterns of the actor model, I can offer an unbeatable platform
Adding a self hosted reddit like suggestion board to Kinn (https://kinn.gg).
We help game developers analyze player feedback from Discord, Steam, YouTube and more.
I am rewriting my pet project: menuop.com . I am integrating AI in the whole restaurant menu creation process. Specifically I'm leveraging the Nano Banana to generate suitable images for food items.
Currently working on a prediction market platform. Although big players like kalshi are pushing this narrative very hard right now i think there is space for a more social focused platform where users can play together.
I got a dumb phone. Been messing around with setting a phone number to call to get SMS directions and things of that sort.
Then I wanted to build my own phone so I got a LTE module and been messing around with that.
About the first part, I am working on something similar for myself. If you want an api to get SMS for free, without needing any 10dlc stuff, check out groupme, which supports SMS.
I've been sculpting a static site generator for myself in TypeScript. The focus is on accessible, clean, and semantic output. It's one of those endless projects but it's fun to work on.
Working on Wordspike.com which I launched earlier this month. It exists to help you extract information from videos so that you save time and get a text to work with. It’s freemium model.
I built Wikli (https://www.wikli.com/) - an AI-powered news aggregator that clusters articles semantically and generates daily digests with editorial oversight.
The Problem: News fatigue is real. Reading 50+ articles daily (from hundred of different sources) to stay informed is unsustainable, but traditional aggregators just dump links without context.
Wikli uses a three-stage pipeline:
Scraping & Processing (Cloudflare Workers): RSS feeds → content extraction → AI classification
Semantic Clustering (Python): Claude groups related articles across sources into coherent stories
Digest Generation: AI synthesizes clusters into readable reports with context and TLDR
Technical Highlights:
Cloudflare Workers + PostgreSQL for scraping infrastructure
Hybrid content extraction (Readability + Puppeteer fallback for tricky sites)
Claude Sonnet 4 for clustering and synthesis (outperformed embedding-based approaches)
Theme-based filtering with relevance scoring (0-10 scale per article)
Telegram bot with stateless approval workflow for editorial control
What's Different:
Semantic clustering beats chronological or source-based grouping
Context from previous digests prevents repetition
Human-in-the-loop via Telegram for quality control (can edit title/approve digest)
Open architecture: separate Brief Generator (Python) and Scraper API (TypeScript)
The system handles rate limiting across domains, AI API throttling, and includes a DataManager abstraction for centralized data operations. Currently live in Italian at wikli.com - language-agnostic by design but focused on the Italian market for now. A the moment running with two topics (AI innovation and Inter Milano Football Club) via Telegram and wikli.com website.
rovr, a terminal file explorer because there just isnt enough competing
using the textual framework, i have proper mouse handling thanks to it, that i noticed was missing in superfile, or just wasnt nice to use in yazi
im taking a look at asyncio to replace threads in the program to hopefully help performance

Im working on (slowly) a very very niche web app to help my wife manage her dog breeding program. Maybe it'll be useful enough for other breeders to use it.
Traditional Knowledge: Constrained to Ibn Seerin's classical teachings — trusted by Muslims for over 1,000 years
AI-Powered Analysis: Unlock the meaning of your dream with 4,300 dream symbols from the Dictionary of Dreams.
Share your dream confidentially, answer a few context questions, and receive your authentic Islamic interpretation in under a minute.
This is an MVP which I started <4 weeks ago. Currently validating Desirability, Feasibility, and Viability.
Confidentiality is very difficult to guarantee. You may want to put some brackets on what your users can realistically expect and give them tips on how they can stay anonymous. But lovely and novel idea, really neat to see these kind of cross-overs.
On the app's dream input page, it specifies a bit more "Your dreams are private and not stored or collected." - would that cover it? Thanks for your feedback and encouragement!
That is a 'pinky promise', it may well be true and let's assume you are well intentioned but it leaves the door open to you not being trustworthy after all or someone intercepting the data while it is being processed (for instance, by compromising your service).
In order for you to process the dream data you have to at least make a temporary copy. One way to get rid of that is to move the interpretation part to the client side if possible. Another thing you could do is if people are really concerned about the content of a particular dream to suggest they use TOR or some other anonymization (not perfect, I know) service to at least hide their internet location from you, the operator of the service.
Does the app itself run entirely within your own infrastructure or does it call out for part of the work?
creating a kanban editor for vscode that can integrate images, videos etc. i use it for planning and creating lectures over several weeks. it can export to a marp compatible presentation format. it's coded with claude, because i would not have had the time to do it othervise.
Tinkering with a tiny macOS app that gives me proactive reminders about the low battery and imminent shutdown.
Standard system notification comes at about 10%, and most of the time, in my case at least, whenever I miss that, the result is "laptop shutdown amidst an ongoing video meeting" or something like that.
(Basically, too late before I act)
Just so that I don't miss the reminders, the app will show an overlay window with some text, following my cursor, and a custom sound.
I built a version this weekend, and am current doing a dogfooding exercise.
- hiragana / katakana / time reading / number reading quizzers
- learn kanji with FSRS, anki-style
- vocab quizzer
- the coolest feature (imo) is a "reader": upload Japanese texts (light novels, children's books, etc), then translate them to your native language to practice your reading comprehension. Select text anywhere on the page (with your cursor) to instantly do a dictionary lookup. A LLM evaluates your translation accuracy (0..100%) and suggests other possible interpretations.
It's all elixir+liveview+postgres+pgroonga (though there are times when I would like to have SolidJS).
I've been considering open-sourcing it due to lack of commercial success, but might try an ad-based approach first.
Postply uses full-context to generate better replies on X, Instagram, Facebook & LinkedIn.
It supports custom reply profiles and styles for support teams and social media managers.
There are clearly a lot of AI replies on social media already, but they are really generic and bad.
With Postply.com I'm hoping it will help people generate better and more meaningful replies.
Currently working on https://rudys.ai to publish and optimise Google Ads campaigns on autopilot.
The idea is to be able to publish campaigns globally in any location/language and also get qualitative recommendations on what to improve. For example, if people have typos in their search terms, Rudy recommends to add it as a keyword so it can maximise the conversion.
When I am not working on my 'job' project, I am working on Ryelang.
In September, I was working on language core, console, generic methods, etc ... but this week I updated integration with OpenAI, IMAP, Surf (browser like client) and then I did few experiments by meshing together these libs.
These few lines proved to be quite helpful for my work email :)
read-file: fn { f } { .Read .trim }
line: "\n----\n"

I've been working on LogChef (https://logchef.app) - a specialized log analytics UI for ClickHouse that focuses on powerful querying and exploration without the complexity of full observability platforms.
The core idea is to leverage ClickHouse's incredible columnar performance for log analytics while providing a schema-agnostic interface that works with any log table structure. It supports both simple search syntax for quick queries and full ClickHouse SQL for complex analytics. Also it has proper RBAC: Team-based access controls for multi-tenant environments.
Off late I have also added some AI features:
- AI-powered SQL generation - write queries in natural language
- MCP (Model Context Protocol) server integration for AI assistants to query your logs
It's open source (AGPLv3) and deliberately doesn't handle log collection - instead it integrates with existing tools like Vector, Fluentd, or OpenTelemetry Collector. The roadmap includes REST APIs, client libraries, visualizations, and alerting.
Built with Go + Vue.js + TypeScript. Currently handles millions of log entries daily in production environments at my org. The deployment is just a single binary deployment with a SQLite DB.
we are ex-Stripe engineers building Lumen Payments. Takes care of webhooks and a lot of boilerplate code so you can implement billing + entitlements really easily.
Working on a original algorithm to explain human behavior from 3rd person perspective.
The whole research is divided into 6 stages. In 2nd stage, I want to use that to mathematically establish the best course of action as an individual.
In 3rd stage, I will explain common psychological phenomenon through the theory, things like narcissism, anxiety, self-doubt, how to forgive others, etc.
In 4th stage, I will explain how the theory is the fastest way to learn across multiple domains and become a generalist and critical thinker.
In 5th stage, I will explain how society will unfold if everyone can become generalist and critical thinker through the theory.
In 6th and last stage, I will think about how to use this theory to make India the next superpower, as this theory can give us the demographic advantage.
I'm writing a programming language for feature-flags/remote-config. I figure a simple DSL has to be an improvement over YAML or a series of forms in a web app.
I'm also generally disappointed by the lack of testing that's performed on feature-flag definitions. So I'd like to have a test runner capable of asserting your feature flag's rules matches your intent.
I’m working on yet another cloud based coding agent https://seniordev.io/ that connects to an existing GitHub repo, spins up a feature branch, commits incremental changes, and opens a PR. You can jump into an embedded VS Code server to review and tweak the code before merging—no local setup needed. Any feedback is greatly appreciated Thanks!
Oh hey I can post an update. My little electronic dictionary is finished. Software works and it's all dressed up in a stealth notebook case. (It runs Python now instead of Lisp though)
I suppose it has moved from “what are you working” to “what have you worked on” territory, but since I wrapped up the website just about a week ago it still feels quite fresh.
Always interested in feedback and what folks find useful! It’s focused on the mechanics of writing understandable software, which I think is especially important in the age of AI slop.
For now, I think it would be funny if you put plaintext that says "just bought the milliondollargpt.com and have no idea what to do with it...". Optionally as a hyperlink to your comment I am replying to.
I have been prototyping a local-only social media manager initially targeting the game development community. I am sick of all the subscription only platforms such as buffer, hootsuite etc.
Initially I have been looking at Mastodon and Bluesky since they have sane APIs.
The plan is to make it so that you can sync your data folder either manually (e.g. dropbox, or sneakernet if you want) or a via a basic cheap data plan.
I've been fiddling with a long-term niche product for WordPress plugin and theme updates. It's 10(!) years old this year. Working in a code base that old 100% of my own commits is both amazing and terrifying. Past me was not as experienced at current me :)
Introducing My Latest Project: An AI Interview Assistant for Job Seekers
So, I've been working on something... interesting. It's an AI assistant that can actually represent candidates in the first round of job interviews. Yes, you read that right—because apparently, we've collectively decided that showing up to your own job interview is so last decade.
Here's how this magnificent creation works:
The system ingests everything about a candidate—CV, professional experience, cover letter, LinkedIn, GitHub, portfolio, and any preferences they've specified (salary expectations, location, contract type, the usual existential career questions). Then, armed with this treasure trove of personal data, my AI conducts automated interviews directly with HR departments or their equally soulless chatbots.
In real-time, it generates responses as if the candidate themselves were speaking—complete with soft skills, communication style, and structured answers. Because nothing screams "hire me" like algorithmic authenticity. If it encounters a question beyond its training data, it politely pings the candidate: "Hey, need some input here before I completely botch your career opportunity."
What this technological marvel offers: 24/7
Availability – Candidates can "attend" interviews while sleeping, working their current job, or contemplating the futility of modern employment practices. The AI never sleeps, never complains, never has a bad day.
Personalization – Responses tailored to each candidate's actual experience and skills. It's them, just... optimized. Debugged. Free of human error like nervousness or accidentally mentioning you follow your passion for underwater basket weaving.
Performance Analytics – Post-interview analysis of how well the candidate matched job requirements. Because self-awareness is overrated—let the machine tell you how you did.
Training Mode – Candidates can practice various interview scenarios and get feedback. Think of it as rehearsing for the day when neither interviewer nor interviewee is actually human anymore.
And yes, the circle closes beautifully.
I'm building a system where AI talks to AI about human employment while humans... what? Watch Netflix? It's efficient. It's scalable.
It's absolutely ridiculous when you think about it for more than thirty seconds.
But hey, if companies are going to screen candidates with automated systems and generic chatbots, why shouldn't candidates fight fire with fire?
Welcome to the employment arms race nobody asked for.
I'm either solving a real problem or hastening our irrelevance. Probably both.
Yet another online cycling calculator, this time with an emphasis on power/speed difference between different tires.
I'm sick and tired of audiophile level bs floating around online forums and I want to create a simple tool for people to fiddle around with different settings to see what really impacts their speed while cycling.
As usual - no plans for monetization whatsoever. Nothing fancy either, just an elaborated weekend project.
If you like the idea and want to help with graphic design and or html just let me know. :)
For the past ten months I've been working on a way to transmit and receive around 10 kilobytes halfway across town. I've blown through government grants totaling in the hundreds of millions of dollars but it seems this is an unsolvable problem.
Esperanto havas la mal- prefikso por krei specialcelan antonomion, sed la rezulto ofte mankas klarecon, kaj kiel morfemo mal mem estas morale kondamna: komparu malica, maligna, malversacio kie mal ne estas sinkrone disigebla.
Tial mi vorkas por krei liston de ĉiuj mal- vortoj kun sen mal- alternativoj. Fakte ĝi ankaŭ povas servi la kontraŭan celon, provizi pli ĝeneralajn mal- vortojn kiam oni deziras krei verkon pli facile akirebla de ĉia nivelo.
Currently a one-man side project:
https://laboratory.love
Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe.
This seemed like a solvable problem.
Laboratory.love lets you crowdfund independent testing of specific products you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid's snacks, whatever you're curious about.
Here's how it works: Find a product (or suggest one), contribute to its testing fund, get detailed lab results when testing completes. If a product doesn't reach its funding goal within 365 days, automatic refund. All results are published openly. Laboratory.love uses the same methodology as PlasticList.org, which found plastic chemicals in everything from prenatal vitamins to ice cream. But instead of researchers choosing what to test, you do.
The bigger picture: Companies respond to market pressure. Transparency creates that pressure. When consumers have data, supply chains get cleaner.
Technical details: Laboratory.love works with ISO 17025-accredited labs, test three samples from different production lots, detect chemicals down to parts per billion. The testing protocol is public.
So far a couple dozen products have received some funding, six products have been fully funded (five product results published, the sixth is at the lab as I write this!)
You can browse products, add your own, or just follow specific items you're curious about: https://laboratory.love
Looking at the tofu reports, I really don't know what to make of them. Is there a way to give more meaning to them for the average person? Also, I'd love to see a sort by "almost funded" option.
Second this, it would be useful to have a "EU safe" label or similar to help me understand if 635.8 DEHP is a good thing or bad.
Thanks for the feedback. Yes, data readability is on the roadmap!
Are you open to code contributions? I’d like to see this sooner than later and would be willing to help.
Or "NON-GMO" label would very extremely helpful too.
That seems somewhat less useful.
Only for the scientifically challenged.
Thanks for the feedback. Yes, data readability is on the roadmap!
Your blog doesn't seem to expose an RSS feed - I'd like to follow your progress.
I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.
Consumer Lab does this testing. It's great, you just have to pay for a membership.
Thank you - had no idea.
I LOVE this idea. Tangentially, a more pimitive case: in trying to recycle or reuse jars or carboard containers food comes in, I wish there was a simple service for ranking brands. For example, some jam jars have labels that can be immediatey removed - others tear and stick to the jar. Similarly, some brands use excessive plastics and packaging, others less so.
I love this!
I keep telling my euro-friends that food and health regulation could potentially be enforced by the free market more effectively than by corruptible government, and this is a perfect example of this.
I'd want to see all products I can buy in there, with all possible chemical, ingredients and nutrients, and clear indications of good/bad, a little bit like in Yuka. You should partner with them maybe even!
1. This doesn't seem to enforce anything
2. The "more free" market in the US seems to have produced worse food, based on what I am reading here
I guess the words "could" and "potentially" are doing quite a bit of heavy lifting here.
Either way, I agree it's a cool project! The transparency is needed, on both sides of the pond.
I agree "enforce" is a poor choice of words. It does not need to be "enforced" using state violence if any consumer can access facts with such transparency. What's missing today is this level of transparency with which the market will just naturally benefit to producer of sane and safe goods in a much more natural way.
Also, speaking of the "more free market in the US", my answer is that you don't hate capitalism, you hate crony capitalism.
> you don't hate capitalism, you hate crony capitalism
What distinguishes this from 'you don't hate socialism, you just hate every so-called socialist government'? I know this seems like lazy smartarsery, but I'm genuinely curious whether you think we have real-world examples of countries doing capitalism right -- and, if not, why that's not a bad sign in the same way that a dearth of examples of socialist success stories is a bad sign.
Wow, great idea, simple website and hopefully a positive impact, not often you see all three in one project :) Good job!
I'm guessing it's limited to US products and US labs? Would love something similar in Europe and/or EU, but it isn't clear if you're limited to US/North America right now, would be nice if it was a bit clearer up front :)
Yeah, I should add something about this to the FAQ page, thanks for pointing this out.
I'm not technically limited to US products, but I can (currently) only test products that can be shipped TO the United States.
Anybody unemployed that would like to try doing this for EU? With the author's green light (or even collaboration)
Really cool project. A quick note, I had to dig in your FAQ to find your definition for LOQ:
> "What does 'LOQ' mean in your results? > > Limit of Quantification (LOQ) is the lowest concentration we can reliably measure. Results below LOQ are marked "<LOQ" - this doesn't mean zero, just below our measurement threshold."
IMO this definition should be on every results page, since most of the pages have more LOQs than anything else.
This is great. I thought about a different model even before plasticlist: make a subscription and test various products, but people will have a number of upvotes based on their sub streak. They vote for food to test, and then you show results to everyone subbed. Kind of like what examined does, but they do deep dives into medical topics for subs. I think this model will work better than the one you currently have. Awesome project anyways!
It is extremely weird to me that countries don't do that on taxpayers money and show the results publicly, this is what they should do.
I definitely considered a voting mechanism, but there are a few million active, buyable CPG UPCs in the U.S. at any given time. When conducting some basic market research for this project, I found that most people are only willing to pay to find results about the specific products they care about.
A couple of suggestions:
The completed entry should include the date of the test results, so currency can be judged,
Ideally the completed entry should contain a scan of the full test report from each of the accredited laboratories.
Both good ideas and on the roadmap!
This is great. We definitely need something like this.
Where are the safe levels limits to interpret test results? This would be a small addition that would make any of the results interpretable. I had to open the PlasticList website to get the baseline safe thresholds for each chemical and to do some rough approximations.
What would be a good strategy to prevent companies from cottoning on to this and gaming the system? They could for example change packaging on production runs for a product that’s undergoing laboratory.love funding campaign.
It's an interesting thought. Companies do change packaging somewhat regularly. However, the underlying skew usually remains the same. Changing the packaging and/or the SKU is very expensive. It's probably cheaper and more beneficial to your company to do your own Plastic Chemical testing and get ahead of the problem.
My suspicion is if this was gameable, this would be a solved problem by a number of companies. The truth is there is no single simple or even hard step to take, it’s mostly like numerous steps that multiple actors would need to do.
I suggest you xpost to Bryan Johnson's Blueprint community. I think might help you get a lot more food tested. That community is probably ICP and also can amplify the message.
Folks at Blueprint actually reached out to me when they saw this project at the beginning of the year and essentially tried to acquire it by hiring me as a contracted engineer. I politely declined.
Blueprint Quantified, which is linked in the below comments, went live after these conversations. Imitation is the sincerest form of flattery.
Blueprint is doing exactly this. I got my cat’s food tested there.
https://www.blueprintquantified.com/
Wow! I'm a food&bev founder and absolutely love what you are doing!
How can I submit my products for testing?
Products can be submitted anytime here: https://laboratory.love/add-product
It just needs to be a product that's available for purchase.
This is so incredibly important, well done. The problem of our food being steeped in plastic hits the news here and there, but it should be front and center in my opinion. Testosterone has been plummeting for decades and it scares the heck out of me. The hormone whose job is "form goals, shrug off failure, and try again!" is being destroyed and corporations are given a free pass to pump us full of phthalates and bisphenol. It's infuriating.
Plastics could be part of it, but three years ago Cleveland Clinic said it could also be weight, sedentary lifestyle, poor sleep, diet, and alcohol
https://health.clevelandclinic.org/declining-testosterone-le...
And anecdotally, I've still been forming goals and shrugging off failure five years into suppressing most of my endogenous testosterone with exogenous estrogen
Have you had your levels checked?
Well that's great for you, but I was making a generalized statement about the role of testosterone, scientific data showing huge decline, and more and more studies linking it to plastics. We can't just alter a key hormone within the span of a few decades and shrug it off. My levels are great for a 40 year old
And yes there are certainly other factors, but that's not what the original comment was talking about?
Theres a cheaper and more pragmatic solution to this. Just inject T lol.
Really nice project. US regulation of food is a joke. Good luck!
> US regulation of food is a joke
I don't know if it's a joke, in the EU we do enjoy a lot more strict regulations, good and bad sometimes, but to me the US system just seems more 'reactionary' rather than proactive.
It is ABSOLUTELY a joke. Downloaded Oasis app last night. My ‘Whole Foods’ water, ya turns out I’m drinking levels above what I should of arsenic, amongst other nasty shit
Can you talk a bit about the tech stack?
React + Vite + Tailwind on the frontend; Netlify Functions for backend with Stripe, Supabase, and email integrations; content via Markdown build script; deployed on Netlify; linted with ESLint; JavaScript-only codebase
LLMs wrote 99% of the code.
The product label images loading on the homepage are huge right now. They are displayed in 128px * 128px box but are about 2 MB in size each. May be generate resized versions at build time and use <picture> tags?
Thanks, I'll take a look at this.
Cool project!
Wow... AI told me that all the tested products far exceed the EU limits!
Love this! But I’m struggling to understand the results
Yeah, I will be doing some work to make the results more interpretable.
I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet).
It uses 4k stereoscopic capture and bunch of ML models to match bone position with sub-millimeter precision. The surgeon screws a metal base piece into the bone, and we detect where that is in space. Then, a Stewart Platform adjusts another part that is placed onto the base. The robotic adjustment allows the base to be placed in a ballpark area, with the robotically-adjusted piece oriented in the exact spot where the surgeon needs to cut.
The net result is a robotic system that is many times cheaper than the least expensive incumbent, decreases surgery time significantly, reduces error, and basically "just works" as opposed to requiring a ton of training. We are debuting at a tradeshow in October.
This sounds awesome! Can you tell me more about what kind of expertise do you need to develop such a system? As in the most important knowledge one most have to be able to work on such a thing
Thanks, buddy! I'm having fun. There are a few sides to it. There are the actual physical surgical tools that you have to design, test, and manufacture. Then there's the robot that adjusts those tools. That stuff is a lot of CAD and 3D printing. The camera is a big deal and it's a ton of work to get that right. Then of course you have all the software, which is a slew of computer vision models that operate on a local computer in a careful dance of resource orchestration. The software has a lot: UI, grpc services, ml models on containers, inverse kinematics for calculating robot position, hardware interfaces, etc. Then there's a bunch of regulatory, validation, compliance, etc.
To answer your question about expertise, it really depends on what you are interested in. We have some dedicated mechanical engineers with medical device experience. The software is handled by a few computer vision and full stack folks. So there's different skillsets.
I'm a bit of a journeyman and as a result, I am decent across all of it. I always did software and went where the wind blew. It's been 20-something years since I graduated so I've seen a lot. About 10 years ago I got a job I was totally unqualified for, which was R&D for a company that made lab equipment for testing gas and oil. I was solo and had to learn all the mechatronics stuff - CAD, microcontrollers, electronics, etc. Check out this video: https://youtu.be/MA6hnyXx4p4. That specific experience allows me to be the glue in our engineering org.
To work here, you don't need medical experience. We have plenty of that. One of the cool things about engineering, especially software engineering, is that you can float around between verticals. I've learned all about media, finance, petroleum, insurance, waste disposal, etc. The skills translate. If you are purely software, I recommend picking up an Arduino and some motors and building something like a simple pan/tilt mechanism with an accompanying mobile app. Just do it. It might inspire you. I think curiosity and enthusiasm are the most valuable traits one can have.
That seems like a long journey. I think playing with Arduino is a perfect way to get started on the interaction between software-hardware. Thanks a lot for your answer!
Building something that combines software and hardware is so rewarding. Reach out to me if you have questions - steve at redefinesurgery.com
So a Shaper Origin for bone cutting? Pretty neat!
Great analogy!
Curious if you’ve heard of OssoVR and what your honest assessment of VR training in your field is?
VR training hasn't really stuck in ortho training. It's legit and people do it, but it's a distant second to doing it live. I haven't seen that much of it, but from what I have seen, the fidelity is quite low. It would be cool to see what a good game studio could produce.
Doctors, like most people, don't like stuff on their head. Plus in ortho there is a lot of feel to it. It's often referred to as "carpentry". The docs I know, especially those with experience, would prefer a video and a cadaver lab. Even that's a lot to ask because they are so swamped. In every surgery there is a rep from the implant company, and those reps are really the ones doing the training.
So there is certainly potential but it's just not to the point where people are excited about it.
Used to work for a major implant company, we had a cadaver lab at company headquarters and flew in doctors for training. The rep in the OR is mostly just for support. They carry in a bunch of hardware in case the doctor needs to pivot midway through, they may need different sized screws or something. They can show doctors how the device is meant to connect together without bone/tissue but they often have little to no medical training, they are sales representatives.
Hey there, thanks for writing. For those who don't know, the sales reps have to carry in racks and racks of parts. Most go unused but the last thing you want is something to go wrong and not have the piece you need readily available.
I've been in many different ORs and I've found that the rep's knowledge and level of participation varies a lot. Some of these reps have been working with the same products for years, the doc fully trusts them, and could probably perform the procedure themselves. Others not so much.
This sounds about right. My time in the industry, I always remember our top selling rep was basically royalty at the company he drove so much volume - but, he was only about 22 and never finished college or had any actual medical training. He just grew up with a surgeon Dad, country club, etc. and had deep connections with a lot of surgeons by virtue of this. He was also very charismatic and a good salesman, just not the guy you'd want training your surgeon before they fused your spine.
"Google maps but for old maps": https://pastmaps.com
This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS .
It gets ~80K MAUs and just slowly and consistently is growing organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun project.
Hey, cool to see!
I'm running a similar but smaller project (5k MAU), my oldest map is central London in 1561
https://onamap.me/maps/London1561/
I got into it because I was interested in the technical challenge of registering GPS to maps which are very warped compared to reality, like very old maps or illustrated tourist maps.
My home page is here for more: https://onamap.me/
I also came across this similar project a while ago:
https://www.verbeeld.be/2024/11/17/using-gps-in-the-year-156...
Good luck continuing to build out the project!
whoa this is wickedly cool! and yes, georeferencing these old maps is the bane of my existence right now
awesome project
I would absolutely love if you brought Canadian maps to this.
I work for Build Canada and I would love to see some maps from the fur trade and early exploration to tell stories.
If you want to chat my email is brendan at buildcanada.com
Hey Brendan! I also would love to add Canadian maps, it's been a huge request from my users and something I've been wanting to focus on all year. A big challenge I have in bringing the service to new regions is just data access, both to raw hi-res map imagery as well as to satellite, LiDAR, etc so this is on my todo list to begin digging into what the Canadian government offers. Brave new world for me
Will absolutely reach out to connect!
There are maps of Toronto
Nice project! The National Library of Scotland has a nifty tool focused mainly on the UK and Ireland that does something similar (with a paid print service attached): https://maps.nls.uk/geo/find/marker/
I love this tool - seeing what was originally on areas. Granted its mostly fields
Really cool! I built the website for an antique maps dealer (Dat Narrenschip) when I was 15 or so and fell in love with antique maps. It's still up and running but now on Shopify.
Over the years I experimented a bit with leaflet.js and thought of overlaying maps too so you can navigate maps through time, but quickly realized it was super difficult. Kudos for setting this up!
If you want to expand to other regions, or chat, or get access to high-res scans, let me know. I think plenty of old maps sellers would love to sell their maps this way.
That's pretty cool, I'll definitely check it out. I've also been looking around for old maps like this.
I also started a small free-time project, where users can download maps as wallpapers for free and put them on their walls :]
https://www.map2image.com
GIS is underrated. This is awesome!
Have you looked into speaking with the various SHPOs in each US State/Territory?
I've worked with several of them a fair bit and they have a ton of old maps hidden internally. Especially for small, specific areas of the state, like historical districts.
I've always wanted a map with a horizontal slider for the year, so I can watch the map change as you slide further back in time.
I know that's different than what you're building, but what you're doing is super cool. Nice work!
That's nice! I have some GIS data of my country it was pretty detailed, it may be outdated now, but covered a good amount of administrative details. If you are extending and need some data on Bangladesh, I can send you
cool! you might be interested in https://maps.arcanum.com/en/ with a lot of European maps
That is awesome. Of course you can bolt LLMs on to any product, I'm thinking AI reviews of (historical) local businesses to give it that google maps feel.
Awesome work. Just out of curiosity, where do you source the maps from? In france IGN has a ton of old maps
Around 90% of the maps currently on the site are from the US government (USGS). The last 10% are from public institutions and libraries and this is the newest segment that I'm actively working on growing. My hope is to flip this ratio with time.
I also have a few partnerships in the work with some private collections but those have proven trickier to actually get to a "yes". It also involves a lot of bespoke work to process and ingest each individual source so I'm not focusing as hard on this type of sourcing anymore.
I would love to use this if it supported Italy
This is brilliant. Nice work
I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups.
Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those services provided all the information on a book. One might provide the series, the other might provide genres, and yet another might provide a cover with good dimensions, but none provided everything, so I decided to work on something of my own (called Librario).
While Shelvica is the focus, Librario could become its own thing in time, so I don’t mind the sidetracking.
I also plan on having a “ISBN Search” kind of website that feeds from that database as a way to let users search for information about books, which then feeds the service’s database, making it stronger for Shelvica.
I open source everything I make, but I’m still wondering if these will be open sourced or not. I’ll probably go with the EUPL 1.2 license if I do decide on open sourcing them.
[1]: My wife and I have a personal library with around 1800 books, but most applications for management are either focused on ebooks or choke with this many books. Libib is the exception, but I wanted a little more.
Interesting! Have you looked into data from Anna (https://annas-archive.li/blog/all-isbns-winners.html)?
Didn’t have the time yet, but it’s on my todo list. I have extractors for Google Books, Hardcover.app, and ISBNDB already working, and Amazon, Goodreads, and Anna’s Archive in the todo list.
I do plan on including a link to the book on Anna’s Archive in the “ISBN Search” website. At least to the search page with the filters already filled.
Hey I'd like to learn more about what you're doing. I'm working on a tangentially related service but focusing on audiobooks. One big stumbling block I ran into early on was trying to find something close to a unified ISBN datasource.
If you're up for it, shoot me an email at charles@geuis.com.
I’ll send you an email later today for sure!
I'm super interested in this, I'm the developer of Kavita and would love to be able to extract metadata from ISBN from user's files.
Is there a Github/Site where I can follow you (or this project) on?
Service isn't online yet, but you can find me on Sourcehut[1] and on GitHub[2], where I'll probably be posting the service soon. You can also email me[3] if you have a request or a specific use case I might be able to support.
[1]: https://sr.ht/~jamesponddotco/
[2]: https://github.com/jamesponddotco
[3]: Email is on my Hacker News profile.
I'd love to get updates on this and talk with you. My email is ben@bookdna.com
We are in the process of building Notion but for books (specifically aimed at your to-be-read list and book log): https://building.shepherd.com/roadmap/launch-our-tbr-app-to-...
Very interested to hear how it goes.
Sending you a message later today!
I need the search service so bad.
I attempted something like this because I wanted a good books search service which provided me at-a-glance information I needed from Storygraph & Goodreads. The main things I look for when I search a book is genres/Storygraph's "moods", number of pages, whether it's part of a series, rating across services & how much does it cost.
Could never make it work properly.
The algorithm to decide what to merge is the hardest part, in my opinion, and very basic right now. Eventually, I wanna try doing something with machine learning. Definitely a fun thing to work on, though.
Having a full time job and a baby to take care of make progress slow, but I should have the website ready soon. Shoot me an email and I can let you know when that happens.. email is on my profile.
I'd love to know more about this project and follow along! I've also had an itch of having a personal library app that's better than libib
Sure, I’d love to keep you in the loop. Send a message to the email on my profile and I’ll let you know once I have something ready for testing :)
I finally collected the courage to release my operating system into the wild:
https://news.ycombinator.com/item?id=45400006
I'm super curious if anybody will pick it up and do something useful with it. This was a couple of years of my life and I absolutely loved working on it but having a child put a hard stop to such entertainment for many years. Now, a good 30 years later I finally found the time to resurrect it.
I'm not sure yet if I am going to do more work on it or leave it as it is, it's good enough to give someone new to OS development a running start and a foundation to build on.
In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible.
Our first dinner was with 13 friends and has since grown into a group of just about 1,000 members. Last year we generated around $140k for local restaurants on off nights (dinners are on Tues and Wed when business is slow).
Now we are working on evolving into more of a lifestyle brand for people who love food. I'm currently working on our clothing line and new site, which we quietly launched a few days ago (there's still a few odds and ends to finish): https://www.deadchefssociety.com. Would love any feedback!
This is an amazing idea tapping unto the one thing we most humans love which is food. Kudos!
That's such a great idea. Especially since you're also helping the restaurants out. Nowhere near that area otherwise I would've petitioned straight away
I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy.
https://github.com/scallyw4g/bonsai
I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.
https://github.com/scallyw4g/poof
That is so neat. I built something a little bit like this for a simulator of a 3D portal mill. Trying it on real wood got expensive fast so for debugging runs and trials of designs I would run a simulation where the toolbit would hack out the shape out of a three dimensional array of voxels. This was then displayed using a very simple engine built with PyGame. I got a lot of use out of that and it saved days (and a small forest).
Great to see something along those lines but with much better visuals.
That's an interesting application! I'm excited to see where these kinds of projects go now that we have so much computing power.
This thing I built was in 2006 or so iirc, here is a screenshot:
https://jacquesmattheij.com/snapshot4.png
Apologies for the low resolution, I don't think I have a better one.
Wow the voxel engine work is beautiful! Impressive work man
Thank you! It's definitely been a labour of love
Cool. Especially love the low dependency approach. Readme says OpenGL 3.3. Are you doing the GPU compute using old-school GPGPU techniques?
Yeah, just render to texture, with one instance of cpu readback (for generating voxel data). There are a couple features I'd like to implement that require 4.3, but I'm pretty committed to the bit at this point. Maybe one day I'll have some optional features.
Do you know the whole story about HyTale? I feel like you'd be an amazing fit to help out there.
I'm nominally familiar with the story. Are you connected to the team in any way? I'd be interested in learning more about the project
"Function" link in the Examples section of the poof repo is 404.
Oh, thank you! Will fix that when I'm at my laptop
Looks so good!
Thank you!
Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics/circuits: https://circuitscript.net/
Recently, I have released a simple IDE (called the Bench) to try Circuitscript online: https://bench.circuitscript.net/
The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circuitscript tool (currently only the desktop cli tool) is able to generate KiCAD netlists and this can be imported into PCBnew.
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so (because this is also part of the design process) and to encourage code reuse.
Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!
As a big openscad fan I love the idea of designing circuits with code.
I do wonder though about designing circuits vs designing schematics. I see you have ‘wire down 100’ making it a more visual language than defining the nets. Be interesting to separate the schematic layout from the nets, so rule base schematic layout can then be applied.
You can actually skip all the wire commands and still generate a valid netlist, however the schematic might be a bit hard to decipher if there are many components!
I did explore automated layout algorithms for components in the schematics, however the readability and flow of the schematics might not be ideal, depending on what the algorithm prioritizes.
In the end, I realized that the actual layout and arrangement of the schematic itself was critical in the overall understanding. That was when I decided to add the "wire" command and give more control back to the schematic designer.
In the future, I do plan to add some automated way to generate these "wire" commands for automated layout. If the designer ever chooses to edit this automated schematic layout, he would be able to edit the wire commands for finer control.
In the end, I do believe that the visual part of the schematic plays an important role in understanding it. I, too, have spent hours puzzling/being misled by poorly drawn/disorganized schematics. Especially during troubleshooting or creating an updated revision, having a good understanding of the schematic saves time.
One of the aims of Circuitscript is to make the visual part easier, so at least more time can be spent thinking and organizing the schematic itself.
I love this idea! Just wanted to send a note of encouragement. Keep at it!
Thank you very much!
I think it may be a good idea to either enable auto-save or remind the user that there are unsaved changes before navigating away from the page.
Yes, that's true, right now you have to manually press on the Save button. I will update the online editor to auto-save after some time and probably also prompt the user to save before navigating as well too. Thank you very much for your feedback!
Hey I am a embedded sw / hw engineer. looks pretty neat. would love to talk to you about it
Sure, let's talk! Please contact me at my email in my profile. Thanks!
I launched Quiet UI this week:
https://quietui.org/
It prioritizes accessibility, longevity, performance, and simplicity.
With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.)
Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode.
All form controls are form-associated via ElementInternals and work with native validation APIs (required, pattern, etc.).
Dialogs, popovers, tooltips, etc. use Popover API for top-layer access without having to portal or hoist.
Some of the more fun components include: Joystick, Stamp, Mesh Gradient, Flip Card, Random Content, Intersection Observer, Typewriter, Lorem Ipsum, Slide Activator
The library is free for personal, educational, non-profit use. Commercial use requires a license.
The "using with AI" support is really interesting, should help bootstrap some serious vibe coding.
FYI the browse components button clips text from the next section on ios
From the text ‘What's in the box?’ Only the W is visible
Thanks! I’ll look into this.
Your docs are great! How did you create them? Did you use external tools to generate them?
I especially liked the browser frame page. It’s so beautifully crafted. I would move the inception example onto the homepage and up on the examples as it is a good example of love put into the whole project and its execution. https://quietui.org/docs/components/browser-frame#embedding-...
Thank you! For the components, I use the Custom Elements Manifest Analyzer to get data from JSDoc comments and TypeScript. This populates properties, events, methods, slots, etc. All the examples and other pages are hand-made. Docs are generated with 11ty.
Awesome components library. Well done! I might definitely try it in one of my next projects.
Very nice, will definitely be using this in the future.
Great work!, love the simple aesthetic
Nice. Great work. Bookmarked
Looks really nice!

The idea is to have deterministic text transformations generated by AI, which can be saved and reused later to avoid incurring/piling up LLM-call cost and hallucinations.
This solves my own pain points when I wanted to clean up some text with non-trivial requirements which takes quite some time to figure out with normal text editor's find-and-replace + regex. Yes, you can write your own code/put LLM generated code in an IDE and do the same thing. However, I just wanted to create a trivial way to generate/save/execute (safely in a local lightweight VM) code to transform my text.
Would love to hear some comments and feedbacks!
Working on orbital dynamics code for my PhD in astronomy, written in rust, it can accurately calculate the positions of all asteroids/comets to within a few meters. Today I am adding a new numerical integration method which should enable me to predict orbits from observations.
https://github.com/dahlend/kete
I'm working on modeling the motion of observed dust particles coming off of comet 67P, here is are some example 3d plots:
Example of rocks ejected from one position and their possible motions: https://dahlend.github.io/67p_beta_dust.html
Trying to determine possible orbits from a set of observations (the straight lines): https://dahlend.github.io/67p_dust_orbit.html
Shout out to pyvista for making these great 3d plots possible, a little less ergonomic than matplotlib, but it can export directly to html.
Hi, this looks amazing! Can't wait to check it out properly tonight. What are you using for numerical integration?
I did this last month: https://www.nhatcher.com/three-body-periodic/ https://github.com/nhatcher/three-body-periodic
There are a couple of half baked integrators there :)
Its an implementation of a pretty standard integrator used by astronomers informally called "RADAU", but it is not exactly the same RADAU you would find elsewhere. Basically it is about as good as you can typically get for multi-step integrators, tuned for speed not precision though.
Note that how the code is laid out you cant really simulate non-solar system masses. Its really aimed at massless objects in the solar system, your 3-body simulations are actually quite difficult to do given the design.
Thanks! Understood, I was more thinking along the lines of reading your code to learn something new. I wish I had infinite time
I suggest the appendix of the arxiv paper if you want to see some of the math required for solar system objects beyond simple Newtonian gravity (like Relativity corrections). I wrote that section specifically because I found it a pain in the ass to source those equations in literature.
Meters?? that's certainly an exaggeration
I'm working on Typegres, a new data layer for the modern stack (TypeScript + PostgreSQL).
My take is that for years, ORMs have hidden the power of PostgreSQL behind generic, database-agnostic abstractions. This made sense in 2010, but now it's a bottleneck.
Typegres rejects this. It's a "translator, not an abstraction," designed to express the full power of PostgreSQL (all statements, built-in functions, etc.) in a type-safe TypeScript API.
The latest killer feature my take of "object-relational mapping done right": class-based models with methods that are actually composable SQL expressions. This lets you extend your tables with expressive logic and fully-composable relations.
It's easier to show than tell. Take a look: https://typegres.com/play
Interesting! have u taken a look at safeql? https://safeql.dev/
I'm personally not a fan of query builders for SQL. it's already a defined language, why are we trying to move away from queries? On top of that SafeQL is only a dev dependency, there's no abstraction. it gets ran through any query client you want
Thanks for the great points and link to SafeQL! I'm a big fan of its approach to bringing type safety to raw SQL strings. For static queries, it's a fantastic solution.
My take is that while "Just use SQL" is healthy pushback against heavy ORMs, a good query builder solves two fundamental problems that raw SQL can't in the application context:
1. Dynamic composition: A query builder is the macro system that SQL is missing. The moment you need to build a query programatically (e.g., conditional filters or joins) you're left with messy/unsafe string concatenation
2. Handling Relations (and other common patterns): Using raw SQL, a complex query with JOINs returns a flat list of rows that now becomes the application's job to properly denormalize. It greatly reduces cognitive load to think in terms of relations, not just join conditions.
Again, showing is stronger than telling. To illustrate, I'd urge you to go through the first couple of examples in the playground and think about how you'd express them (e.g., the composability of the "example1" query) in something like SafeQL: https://typegres.com/play/
Neat idea. Would you say that biggest difference from something like Kysely is the focus on extracting common calculated SELECT targets into methods that can easily be accessed when querying? Or perhaps it's more thorough with providing TS versions of all the SQL syntax available? The list of reference fields/methods in your docs is certainly massive.
Thanks! That's a great question.
First off, I'm a huge fan of Kysely and it's a massive source of inspiration for Typegres.
You've nailed the two big differences:
* Architected for Business Logic: The primary innovation is the class-based model. This is all about co-locating your business logic (like calculated fields and relations) directly with your data model. The cool part is that these methods aren't just for SELECT; they're composable SQL expressions you can use anywhere: in a WHERE, an ORDER BY, etc. The goal is to create a single, type-safe source of truth for your logic that compiles directly to SQL.
* PostgreSQL-Native: The other fundamental difference is the focus on going deep on a single database rather than being database-agnostic. That massive list of functions you saw is a core feature, designed to provide exhaustive, type-safe, and autocomplete-friendly coverage for the entire PostgreSQL feature set. The philosophy is to stop forcing developers to reinvent database logic in their application code.
Philosophically, it's a shift from composing type-safe SQL strings (like Kysely, which is brilliant for its WYSIWYG approach) to composing SQL expressions as if they were first-class TypeScript objects.
Cool, that makes sense. Thanks for the explanation
Very cool!
Thanks, glad you think so!
I've been making and selling my electronic social battery pin badges for a while now (https://hortus.dev/products/social-battery) and I'm expanding the range with seasonal versions like a Christmas mood badge, and a halloween themed ghost badge that's coming soon. I'm lucky enough that these projects have gone down well and are making enough money to fund some more complicated (and expensive) projects that I wouldn't have otherwise had the guts to try. Currently I'm working on an RGB digital sand timer with customizable timing sequences so that you can use it for things like the pomodoro technique - I have a working prototype and at the moment I'm experimenting with interfaces for setting the sequences. I wanted to use a combination of buttons and an accelerometer for this but it's not as intuitive as I'd like so I may end up making a small smartphone app to configure it.
Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics.
I've been playing guitar for a little under 6 years and ran into the common problem among many intermediate guitarists fall into, which is stagnating into a plateau at a certain BPM.
The most effective solution I've found is to take the top speed hit playing a chunk of a lick and simply increase it 20-50 BPM past that limit, attempting one's best to stay in tempo. Regardless of how sloppy it sounds. Then roughly halve that increased addition of BPM, it will become relatively easier to play. For example, if you are stuck at 120 BPM, upping it to 150 BPM with sloppy attempts, then dropping it back down to 130-140 BPM.
I've gone cleanly from alternate picked 140 BPM triplets to 220 BPM triplets in two months after being stuck at 140 BPM for over a year with this method. Sometimes even hitting 280 BPM triplets when I have the focus and time for it.
Even then, I want a more consistent, and variable way of customizing a practice session using a metronome from a hobbyist perspective without using a DAW. With a simpler interface for doing so. As well as encourage with said method above for other guitarists in the pursuit of speed.
When I was 14 I would have wanted to "shred at 220bpm" but today I wouldn't get my wallet out for that. What I really would pay for is help getting into the pocket.
Anyone who can read a guitar tab can play the notes of "Superstition" by Stevie Wonder. But simply playing the notes against a metronome sounds mechanical -- the song only comes to life when you get the timings right (both the note attack and decay have to be timed for a "swing.") A good swing will practically force your audience to start dancing to your music -- it's magical! But it's very difficult to learn because regular metronome practice won't achieve it.
If you're measuring "rush and drag" against a straight metronome, could you also measure against a swung time, perhaps against timings extracted from in-the-pocket songs we know and love?
> When I was 14 I would have wanted to "shred at 220bpm" but today I wouldn't get my wallet out for that.
That's fair, essentially why I put "shred" in quotes originally is that shredding guitar isn't necessarily playing fast. You laid out a nice example with Superstition for that.
I don't see why that couldn't be implemented in some way (accenting specific notes and different sustain times).
What would be difficult is quantifying note attack exactly for XYZ's riff sections. I.e., what constitutes a relative baseline pick attack and the target pick attack. If we are using a float and define the "normal" attack as 0.5, then how do we know, for example, the first or fifth note in the iconic Superstition riff is 0.85? Is it empirical?
Either way, that is a lovely insight I will consider. Matching another guitarist's intonation down to a tee can be extremely difficult, but very rewarding.
> What would be difficult is quantifying note attack exactly for XYZ's riff sections.
At 60 BPM, mathematical quarter notes are 1000ms apart. But in a pocket groove, you may notice that every other quarter note is "late", or "swung":
If you load a groovy song in Audacity you should be able to see these inter-note delays.Another factor that affects rhythm is note duration relative to the tempo -- you'll want to measure that too.
> Matching another guitarist's intonation down to a tee
I suspect if you study a few groovy songs you'll find there's just a slightly different note grid that's common to these songs (there could be more than one grid!) Teaching this grid (rather than teaching one specific song) will help the student learn to shift notes away from the the mathematical metronome placement. This skill will equip many of them to mimic the feel of their favorite artist by ear.
I see what you mean now. I interpreted note attack as pick attack, which is traditionally defined as how hard a given note is played with a pick.
Yeah, swing usually has uneven subdivisions. Funk is almost always syncopated, and depending on the style, can be a mix of syncopation and swing.
This goes back to how you noted simply using a metronome will give that mechanical, or even a soulless characteristic, to playing a piece which inherently has a soulful quality about it. And with respect to intonation, there's a lot more that goes into that than just timing it right (how hard fingers are pressed on the fretboard, the pressure between fingers holding the pick, the angle of the pick, where the pick strikes relative to pickups, the pick attack, accenting notes, etc.)
I do love this idea of being able to apply some "in the pocket"/"swing" deviation to a metronome sequence. I agree with you that it adds that magical musical quality that people would instinctively dance to.
Accuracy indicators for rushing and dragging are very useful, but equally interesting would be an indicator that checks for a consistent peaks, so every note is played with equal volume. A dream would be if your app can detect differences in sound (fingernails occasionally scratching the string, fretbuzz).
Is there any way to get notified when your app is done, or do you have a name for it already so we can search for it in a couple weeks?
Love those ideas, would be awesome for really nailing down consistent tones. Latter one would be fairly ambitious for me but I'll keep it in mind for future improvements.
Just published the waitlist[1], the app will be called ShredBlocks.
[1]: https://shredblocks.app/
My AI suggests a few existing algorithms to tackle the problem of comparing two sound curves - maybe this one is not too hard?
I'll check out that app when it's ready, good luck!
Thank you!
Reminds me of John Petrucci's Rock Discipline instructional video where he outlines exactly this technique on how to build up speed.
Great instructional video. First place I learned E natural minor with his scale fragments section.
Yes, not a new technique by any stretch of the means. AFAIK John Petrucci takes a less aggressive approach with raising BPM. Funnily, Shawn Lane goes into a very similar methodology >30 years ago[1].

Beautifully designed IMO.
Unfortunately not a sequencer, which would be a programmable set of a series of blocks with different tempos, time signatures, subdivisions, etc., played in single sequence.
When will it be done? Would like to try.
At least a couple more weeks. Hopefully less than a month out from now.
I have most of the UI done for sequencing. Workflows for speed building and metronome sequencing will be completely free, which is also a top priority for me to get out the door first.
Release engineering for FreeBSD 15.0-RELEASE. Major releases are always a lot of work, but this is probably the biggest release in 20 years due to the new base system distribution system landing. (We're switching from "here's a tarball containing everything" to "here's 500 packages", with resulting changes in the build process, download/update mirrors, installer, etc.)
What's the ETA?
Target is 2025-12-02 00:00 UTC.
Given that this is a major release, there are fairly wide error bars on that; it could be as much as 3 weeks earlier if the first release candidate turns out to be perfect, and of course it could be later if things go badly (but I very much hope to get it out by the end of 2025).
That's a massive job. Much good luck, and a lack of gremlins!
Definitely a massive job. Some FreeBSD developers have stepped up to volunteer tremendous amounts of help (and also the FreeBSD Foundation has paid staff helping out with parts of this) but my best guess is that I'll be spending around 300 unpaid hours making this release happen; I've been doing pretty much full time hours on this in September and I'm really hoping that once pkgbase moves from "need to implement the stuff which isn't implemented yet" to "need to iron out some bugs" I'll have time for other things... like my paid job, Tarsnap.
I’ve been suffering from migraines for the past year and the health system hasn’t been too helpful in diagnosing why. I’ve got some meds, but they’re expensive and not without side effects. So I’m building an app to try and figure out how to avoid the triggers in the first place.
https://dotsjournal.app
Sort of like a digital bullet journal. You setup some rows of events you want to track, then just tap for when/if that events happens. It’s already helped me spot certain triggers for my migraines, which I can now minimize. My wife has been finding it helpful to diagnose sleep problems. I think it might be super helpful to others with trying to understand lifestyle choices and how it impacts their wellbeing.
About to roll out the beta. Hoping to have a full release by the end of the year.
It’s my first iOS app in 8 years! Learning SwiftUI after UIKit has been quite the shift.
> some rows of events you want to track
Neat.
I also created a grid for habit tracking (for chronic pain mgmt). Day of month across the top, all the things I'm supposed to do along the side. Something to share and discuss with my care providers.
Mine's just a spreadsheet that I tweak and print every month. (Then added to my discbound clipboard organizer, that I bring everywhere.)
I haven't had the gumption to digitize my effort. I really like the physical check lists. Though I've wondered how a hybrid solution might work. eg vital signs added automatically to digital version via Health.app. eg scan printed copy and magically fill in the digital version.
I look forward to seeing your app.
That’s precisely how I started too! But opening the spreadsheet on my phone to try and log something got to be tedious. Especially while actively having a migraine. I figured an app could ease the difficulty a lot.
I appreciate your interest!
Best of luck and wish I had something like this a while back. Took me 4 years to figure out my triggers and one of them was pure luck.
Oof, 4 years living with that, I’m so sorry! It’s been so frustrating not knowing when/if I’ll have one, regaining some amount of control eases the pain a bit.
On the side, custom coloring books for kids using nano banana, started with a project for my son, and its a little janky for some photos but have had some interest already: https://bespokebooks.io. I think it needs to be a phone app to really work for most people though, so that's next on my to do list besides some prompt tweaking.
Notebook to do it yourself here: https://github.com/dbish/bespoke-books-ai-example
I think there are a lot of really fun projects possible now in the child book creation space, particularly as you build tools that they can use themselves (like adding voice interfaces to building a book or story).
This is outside my 996 job of AI Agent/Assistant infra + ops :)
I've had similar ideas involving bespoke print on-demand books, could you share how you actually get these printed/published?
Currently using Lulu because they have a developer api and allow printing a single book programmatically, many places I found either didn’t have an api or required a min order of books that isn’t needed for a one off custom design. https://developers.lulu.com/home
My hope for this project is to get enough demand that I have an excuse to figure out a printing option myself and buy some new equipment :)
Do you also send these books to Germany?
This is truely awesome and reminds me of the project that was making a litle one story book with the child as the main character. It was at least a couple of years ago I think.
I'm working on Small Transfers (https://smalltransfers.com/), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers.
You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets.
If combined with subscriptions, the pricing can work similarly to mobile plans, where monthly plans become cheaper above a certain usage threshold.
Looking for more developers to try it and share feedback.
Resources: integration guide (https://smalltransfers.com/merchant/docs/integration-guide), a quick walkthrough (https://youtu.be/WQW5fiUFNRk), a Next.js template (source code: https://github.com/smalltransfers/nextjs-starter, live demo: https://nextjs-starter.smalltransfers.com/), an AI template (source code: https://github.com/smalltransfers/ai-starter, live demo: https://ai-starter.smalltransfers.com/).
Do you know https://en.m.wikipedia.org/wiki/Flattr? They did something similar.
Flattr was a micro-donation subscription service where users set a monthly budget that was allocated to creators.
Small Transfers is for usage-based billing of online services and APIs. There is no monthly budget, wallet, or pre-funding. Customers are charged only for actual usage.
Please consult how "blik" works in Poland. It requires a bank cooperation, but it ultimately became a standard here for payments as an alternative to debit/credit card payment.
BLIK is a bank-backed payment method used at checkout.
Small Transfers is an API for a merchant to charge a customer tiny amounts (as little as $0.000001), which are batched into a single card charge via Stripe.
Do I understand correctly that in order to pay someone through your service I need to first create an account and then link it to a conventional card?
If so, it's ultimately a PayPal remake?
Customers do create an account and provide a payment method, but they don't pre-fund or hold a balance, and they don't initiate a payment. Small Transfers is an API that allows merchants to charge very small amounts programmatically. At the end of each month (or earlier, if a threshold is reached), we charge the customer what they owe. This makes the tiny charges viable and avoids death-by-$0.30.
It's not a PayPal remake, since there are no wallets, no P2P transactions, and no stored funds. In addition, Small Transfers allows very small charges (as mentioned above), and provides customer OAuth and spending caps.
if the customer owes $0.001, how are you charging that?
If a customer's balance is under $1 at the end of the month, we delay charging them for up to 60 days and send email reminders. If it's still under $1 after 60 days, we charge at least $0.50 and credit the difference (after fees) to their account for future use.
> ultimately a PayPal remake?
Pretty sure you can't send tiny fractions of a penny through PayPal.
you could using gripto
From what I can find, Gripto was a cryptocurrency platform for viewing holdings, market info, and relevant news. It seems that the service was retired in late 2018.
it’s just a derogatory nickname for crypto lol
Working on a webapp for critically think with others about a problem.
The idea is that you build a diagram that contains all the details about the problem and people's thoughts on it, and it's organized in such a way that it's easy to just keep refining, down to the smallest detail. So you build this concrete, shared understanding, and move it forward and forward, until hopefully y'all can make some best decision to improve the situation.
There's a lot to do. Currently working on UX to allow hiding intermediate nodes and still have indirect edges drawn. Want to add an LLM integration to generate/update diagrams via natural language, which I think will help a lot with usage barriers to using the app.
Happy to get any feedback :) https://ameliorate.app/ https://github.com/amelioro/ameliorate
Reminds me of https://github.com/arguman/arguman.org
I wanted something similar for a worldview. I want an app where I can dump all the things that actively go into shaping my worldview and then when someone wants to know why I think the way I do, I will share them the link of my worldview board. We are not famous people to have our memoir written but this is another way to peek into minds of strangers.
That's a cool idea. Seems like there would be a ton of things contained in an individual's worldview, that it'd be hard to build all of it up. Perhaps when you encounter something that makes you think of some core philosophy, you note it and the philosophy, and eventually there would be a loose picture that forms amongst all the relations.
Certainly would be helpful for trying to understand someone else. Not sure if this is totally appropriate, but it does seem like something that a chatbot would be good at combing through to find examples to suggest why one thinks a certain way about a new topic. You could even ask it about your own worldview!
Non tech, but I started a sports beverage company with my brother and a neighbor. We are based in South Florida.
My brother and I grew up playing sports and remember the simplicity of home-made drinks we'd take to games that blew the likes of Gatorade out of the park. We aim to replicate the simplicity of home-made drinks with simple ingredients.
https://www.drinkiso.com/
Our whole value-add is based around the fact that most sports drinks or hydration drinks contain a lot of junk. We are opposed to the bullshit catch-all that is "natural flavors" and believe in product transparency and honesty. Our products straddle the line between fresh-pressed juice and sports drinks. Our prices are definitely on the higher end, but with scale, we can lower them.
We currently are in growth mode - and currently are one of the best selling products in the top boutique gym chain in the Miami area, as well as going strong in all SoFLA Equinox locations (except for the WPB location which isn't open yet).
We do sell online but shipping is a PITA as overnight shipping costs for cold products are astronomical. When we find a cheaper solution so I can ship around the country, I'll let everyone here know :)
Based in South Florida (Miami-Dade, FtL, West Palm)? DM me and let's meet up!
I can't find the nutrition information anywhere on the site. The first thing I look for when I see "no sugar added" on any product is the sugar content. Not being able to see that before buying is a no-go for me.
Great point! I will add it to our site.
In terms of our sugar content, is 16g sugar and 17g sugar, respectively. (2 of our flavors are 17g, one is 16g).
In terms of "no sugar added", it's true, we don't add sugar. But we have natural sugars involved - our drinks are made with real fruit which obviously contains sugars. But we don't add stevia, fructose, or anything like that.
Part of hydrating effectively is adding sugar to your bloodstream as well as salts, etc.. in the right balance in addition to water / liquid.
Pretty cool, I’m sure you’re well aware but I feel like the powder packs are the future here. Makes E-commerce more feasible too. Have you looked into this? Guessing the fresh part rules it out?
Writing as someone that’s switched to liquid iv and have tried LMNT and a few others.
>Have you looked into this?
Yes. I get asked this frequently. I don't want to follow the same trend bandwagon that it seems everyone is on. Stick packs taste fake and often are loaded with non-essential junk (the FDA also doesn't regulate a lot of supplements).
A lot of stick packs are also leaning heavily into "natural flavors". A lot of our customers are people who go out of their way to avoid "natural flavors". If I put something in my body, I want to know what that something is, and I don't trust some catch-all term abused by corporations who put harmful chemicals in their products.
>Guessing the fresh part rules it out?
Correct. Gatorade is my competitor, not LMNT. If you're a fan of stick packs, you can replace LiquidIV/LMNT with half a teaspoon of pure sea or pink salt and a few drops of fresh squeezed lime and/or lemon juice in your water bottle. The end result will effectively be the same but you'll have more control over the flavor and saltiness. And it's cheaper.
Thanks for the response. Certainly respect your direction but I happen to think the trend will mature versus fade away. I know you're going after this certain niche, which I understand, but I don't think most people care as much about knowing exactly what is going into their bodies. I mean, sales and the average American diet proves as much. For me, the convenience of keeping a packet in my bag/desk/car/etc for weeks or months far outweighs the control over flavor and cost. Also usually prefer a tropical punch flavor over lemon/lime and that's more difficult to recreate on the fly (probably "natural flavors" lol). I don't have a workout regimen I just sometimes do work that is labor intensive and it helps me recover. It's usually an unplanned activity and the powder stuff is stable and available when I need it and really that's all I care about. I haven't even looked into the ingredients to see what it is that is actually helping me, but Liquid IV definitely is helping me recover and feel more hydrated than Gatorade ever has. Helps with cramps too, which I just assume is K but again, I haven't even looked. Just wanted to share my "customer journey" as anecdata, obviously no right/wrong path here and it's your company to push in whichever direction you want. Best of luck with it, I will give it a try if I ever see it in my area!
I’m building a daily word puzzle game with a twist!
In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword.
You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got.
I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every day!
So far I’ve gotten really positive feedback and have around 100 people signed up to get notified. It’s been a lot of fun to build!
Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once.
That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.
Thanks! I experimented with this but struggled making it feel natural on mobile.
I ended up implementing an alternate solution that I’m hoping solves for the same paint point.
My current dev build “merges” tiles when you connect them to complete a word. This allows you to move them as
I’m going to release a demo with that feature soon. My core playtesters seem to like it but I want to get more feedback on it from a larger group!
Merging is exactly what I expected when I put chunks together, with tap to separate them again.
The UX is phenomenal. Easily in the top 1% of daily word puzzles. Love the concept, I'm sure it will do well at your launch!!
This is such a nice comment, and I only checked out the website because of your comment! I am glad I did. Indeed a spectacular puzzle.
That’s lovely to hear! Thank you!
playlin.io is super cool! Nice job! I’ll submit my game there when it launches :)
Thank you! Happy to feature your game, I've played a _lot_ putting together Playlin so I have a pretty good sense of what's out there.
Really cool, congrats! The UI is clean, everything is smooth, I like it :) Can't wait for the release
Thank you!
I shared this with my colleagues at work. Got this feedback:
> This is amazing. I could lose days to this.
That’s lovely to hear? Thanks for sharing it!
Love this - did you buy the name or was it free to reg? (nosey!)
It was available to register at a normal rate!
love the UI! one feedback I have is it would be nice to be able to use arrow keys on the desktop website to move the tiles
Thanks! Keyboard support is on my road map
I'm creating Comper, an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select the repos for your team (or if you feel confident, of the entire org), you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.
My initial announcement got the top spot in "What are you working on? (February 2025)" https://news.ycombinator.com/item?id=43157056 but now I'm a lot further, there's a website https://comper.io and the company is getting incorporated within two weeks.
Last week I showed it off in the Feeling of Computing Meetup (fka Future of Coding) - the recording is here and the reactions were extremely positive https://www.youtube.com/watch?v=3-rg-FPZJtk
I'm opening the private beta soon, where I mix using the product with consultancy, to get better customer feedback. Not sure if that will work, but I don't have all the features yet for bottom-up adoption.
The video is not loading on FF fyi.

FF.
Working fine using Windows 10, Firefox 143.0.1 (32-bit), old desktop for web facing browsing etc.
TBH I would have thought it would have been a 64-bit version, regardless, it's not a universal FF issue, more a your-setup specific hiccup.
Thank you, can not reproduce yet but will investigate.
I'm on the cusp of launching an interior design software I have built with my partner (she's the interior designer, I'm the coder).
https://inspec.design
My read of the industry in terms of software is that it's split into 3 groups:
1. Interior visualisation (basically 3D renders) which largely target the what-if amateur market
2. Big, clunky and old software tools for professional interior designers working on huge projects, which works well but has that universal sort of mild dislike to strong disdain depending on the person
3. New players who want to replace the old clunky software
Seeing this, we decided not to try to overthrow the old all-powerful project management solution, but rather to replace a single process in the interior design workflow. And of course to do it very well.
Working with a partner has never been a problem, don't worry.
I'm currently building Visirya, an app that helps people record their night dreams and transforms them into short videos and written journals. The bigger goal is to use this dream data to create dream cartographies, essentially maps of recurring themes, emotions, and symbols—to uncover patterns and insights across dreams over time.
So far, we've built the video generation and dream journaling features. The app is live on TestFlight, and we're preparing a major update soon that includes a new better UI, and dream questionnaire to help with pattern recognition and dream mapping.
Would love to hear thoughts, feedback, or connect with others working on similar intersections of tech and the mind! If you're interested in trying it out, you can find the TestFlight link on our website: https://visirya.com
Super cool! I'm building in the same space but for Muslims - Dreamstate: Interpret your dreams Islamically https://dreamstateai.replit.app/
I tried your app - it's quite abrupt to go straight to Access Microphone permissions. The voice recording took a long time to analyse, it timed out for me. It's a great idea but didn't work for me unfortunately.
The idea is nice, but I wonder if a generated video can have any resemblance of the actual dream. At least for me, dreams are very tied to emotion, and the visuals are kinda blurry, so i don’t know if that sort of thing can provide any satisfaction. But I know certain aesthetics can feel “dreamlike”.
https://github.com/little-book-of/maths/blob/main/books/en-U...
I've been working on a book called "The Little Chronicles of Mathematics, Data, and the Mind of Machines", this is a 100 sections journey from counting stones to thinking silicon. This book is more like a storybook for curious builders. I wrote it for people who love see how things connect, how math become language, how data become memory, and how machines learned to reason. If you enjoy clear ideas, and big arcs of history, this book is for you.
Thank you for showing this. I am slowly working on a book with a similar goal as yours. Your book is very interesting and inspiring. Your work might have gone unnoticed by most, but not by me. Big respect for sticking to it and not giving up.
Thanks! Feel free to DM me if you'd like to collaborate, I would really love to hear more from you. People often ignore this kind of work, but at least I had the courage to share it.
I skimmed this and it looks like a remarkable work, and clearly you've put a lot of time and love into it. What inspired you? What are your next steps? Also, how do you deal with the disappointment of too few github stars? What is your success criteria?
I'm launching a new product for my clock-making business: https://DigitalHorology.com
None of my clocks tell the time.
They're all fully automatic GPS-enabled timepieces. For a couple of years I've been developing, hand-making, and selling these clocks that track the moon phase, the sun's position, etc.
My new idea is the tide clock "NautiKron." It's getting a lot of interest from US coastal buyers.
NautiKron seems to show the current hour in the top row. Why not project it on the tide curve?
Putting the marker inside the tide curve would give it a cleaner look.
I considered it, and figured it was more legible to have the hour marker directly under the numbers. People looking at the NautiKron from across the room or who have low vision might like it better this way.
Good idea to revisit -- I'm always tweaking the designs and responding to owner feedback.
Thanks for the comment!
Love these! Where did you get the idea? Would love to know more.
Thanks! I posted the story here: https://www.etsy.com/shop/DigitalHorology?#about
I started a newsletter that tries to recreate the original magic of stumble upon. To feature cool random stuff from across the internet.
I believe the old internet is still alive and well. It's just buried under a mountain of shit.

Neat! I don't love newsletters though, any chance you may be publishing this using ActivityPub too?
(Sorry if this sounds entitled, it's a genuine "do you have plans" question)
Honestly? No, I want to stick to the concept, one email and 1 URL a day (Monday - Friday)
that's fair, thanks for answering.
Nearbywiki is a really neat find. Thank you for doing this.

Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!
I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)
As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.
[1] https://pushscroll.com
Neat idea, but how does that work? Can an app limit other apps? I didn't know it was possible.

On iOS you can do that using DeviceActivity framework, iirc.
Very much a hobby, but I'm working on a Pinterest alternative built on ATProto called Scrapboard[1]
The Bluesky ecosystem is a really great platform to build social media on and with Pinterest being overtaken by AI content I figured I'd give it a shot. There is definitely not as much content there, but it is of much higher quality and the culture of providing alt text on images really makes search work rather well.

Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1].
Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my mom got for me for Christmas when I was a kid.
I hope to sell them and then probably never recoup my investment.

(I'll leave it as an exercise for someone clever to figure out what circuit is being depicted in the photo.)
Very cool! Where's the loopstick antenna, CdS cell, and meter, though? :)
Ha ha, patience… Wait for the sequel. There's only so much room on a breadboard.
I'm not great at electronics, but it looks like it alternates turning on the two LEDs.
That's probably it — an astable multivibrator.
I’m building https://www.kidcarekit.com, a Rails SaaS for family-run daycare centers that still juggle spreadsheets and phone calls. It wraps waitlist management, enrollments, and Stripe billing into a single dashboard with Tailwind + Hotwire on the front, Devise for auth, and Azure Blob for logos. Solid Queue handles scheduled jobs like weekly tuition and late fee automation so owners get predictable cash flow without hand-cranking invoices, while MailerSend keeps parents in the loop.
Right now I’m polishing the onboarding flow so new centers can import families, configure their billing cadence, and connect Stripe in under ten minutes. Next up is richer analytics (occupancy tracking and revenue health) and rolling out a guided setup for late fee policies. If you’re running childcare ops or know someone who is, I’d love feedback on the workflow pain points you still feel daily.
Looks like a hell of a lot of value for $15 / month.
I'm trying to make an RF lightning detector small enough to trivially add to my motorbike.
I live in Viet Nam, and driving through bad storms this time of year is pretty miserable, and they happen fast and are local enough that weather prediction is not terribly useful.
There are a lot of problems with EMI. Lots of ungrounded brushed motors everywhere that make the RF bits hard. If I succeed, I'll publish the PCB designs.
I've also got some educational products in production right now, about Vietnamese history. I'd share a link, but my website probably can't handle the traffic right now.
Building Evidentia – platform for scientific knowledge that never gets published
Science's most valuable output never gets published. Negative results, failed replications, protocol details etc. all vanish into the file drawer. This means that the public body of knowledge is slow and also often wrong.
The cost: 70% of researchers can't reproduce published findings. Only 6 of 53 landmark cancer studies replicated. Industry wastes $28B annually re-validating work that doesn't hold up.
We're building a platform to capture what gets lost. Scientists share the details papers omit: failed antibodies, critical protocol tweaks, replication attempts. AI + a graph DB structures it into queryable data. Contributors get DOIs so it counts as real academic credit.
Been testing with beta users for 2 weeks. Opening up waitlist now: https://evidentia.bio/
Key challenge: will scientists share without traditional publication incentives? Early signal says yes (especially younger researchers), but needs to scale.
Feedback welcome, especially on keeping it alive (avoiding the "data graveyard" problem) and monetization.
I love these threads, and always learn or pick up something new.
From my side, I've been working on a multi-lingual first words book for a baby. None of the published books have our mix of languages (which is fair enough, I don't think there is much of a market for it!) and so I decided to create our own. It's just images and then the word translated into three different languages alongside it (like a typical first words book). I used Google's AI for the images, and it has done a surprisingly good job of creating baby friendly images, with enough detail to spark interest.
The other tangential benefit is that I found it awkward to speak in my mother tongue, but having this book helps break that by having me speak in that language and then leads to it feeling much more natural in other contexts with babies.
This is not very technical project (though if I had the time it could easily become a fun project where people select their unique mix of languages and the book gets produced).
If anybody is in a similar boat and wants to produce their own version for their mix of languages then please let me know and message here - I will happily share the Canva file with you (you'll just need to write in the words yourself). (This idea of sharing is inspired very directly by Derek Sivers 'Sharing' idea [0])

I started a company to grow unlimited eggs from stem cells, based on the work from my recent PhD. This will solve nearly all female infertility and help prevent genetic disease.

Best of luck. I've known so many people in my circle deal with infertility and miscarriages. Hope you succeed.
You might just beat the Mombasa Hatchery and Conditioning Center's record!
Do the same for chicken eggs
Are you making a joke, or is there some use for that? (I would think of all species on earth, chickens are the easiest to get eggs for once you exclude the insects, but lack of domain knowledge means I could easily be missing something)
Not OP but I think there are a lot of people (maybe mostly vegans) who would be interested. I have no thought on whether it would be financially viable.
I'd be interested just because I'd rather use non-animal alternatives if available.
I hope lab-made milk becomes a viable thing even though I'm not vegan or vegetarian. Lab-made eggs would be good too.
Not the person you asked, but there is a lot of research in this for meat so it would be interesting for eggs as well, as replacing them when you are vegan is not that easy.
Not a joke. I'd pay x3 for lab grown eggs.
As someone who's dealt with this and know more people, good luck.
You're doing God's work, pun intended.
I've been working non-stop on my game development tutorial website:
https://raizensoft.com/tutorials/
Currently it mainly focuses on libGDX which is my most favorite framework. I prefer code-centric approach because that's how game development should be in my opinion.
Most of the tutorials are just pure coding with algorithms explanations. My goal is to build one of the most resourceful website for libGDX because it's quite underserved at the moment.
In the future I may expand to other code-centric frameworks and more general game development topics, let's see how it go.
First time hearing about libGDX. Do you have any resources on why it's your favorite framework? It might be useful for your website as well. To sort of "sell" the framework to game developers who have not used it before.
libGDX is not in the same spotlight as Godot or Unity but still popular within Java devs circle.
I'm not aware of any resources explaining the "why libGDX" but here are some differences, speaking from my own experiences:
- Code oriented development, no authoring tool, no drag and drop, just you and the API, which might attracts traditional devs who prefer a pure coding approach.
- Very thin abstraction over the platform graphics layer, it just adds a few more drawing APIs over the underlying graphics API (OpenGL and WebGL). You’re free to build your own abstractions on top of the core APIs.
- Java, while might be verbose, is very stable, easy to learn and has huge ecosystem. Or you can just use Kotlin.
- Once you learn the ins and outs of the framework, it actually has a greater sense of freedom compared to Unity, Godot, Unreal, etc because those engines always force you to do things in their own opinionated ways.
Great, I will check it out, I am a Java dev and always wanted to learn about game programming!
I'm pursuing my vision of "music-i18n": Open source music software that works for microtonal music and worldwide musical cultures.
It's not a from-scratch effort, quite the contrary: I'm trying to tie in existing music standards (MIDI, MusicXML, SMuFL, MEI, etc.) and ensure that FOSS systems (MuseScore, Verovio, smaller components) implement enough of those standards to support music-i18n.
Sometimes, this also includes extending the standards themselves when they are not fully capable of representing some non-mainstream musical aspect. For example, MusicXML lacks the ability of representing multiple accidentals per note (whereas MEI does), which is a must for microtonality.
I started down this path around 2018, as a music player who got interested in arranging Arabic songs in a "Real Book" style. It opened a giant rabbit hole that I'm still far from having fully explored.
Now and then, I collaborate with other devs who are interested in adjacent topics. I would love to hear from some of you here!
As an entry point, I recommend checking out the "progress report" I wrote last October: https://blog.karimratib.me/2024/10/01/music-grimoire-progres... - I'm currently drafting this year's update. My main demo is at https://blog.karimratib.me/demos/musicxml/
Building https://fallinorg.com/, a Mac app that organizes your files.
It looks inside each file to see what it’s about, then moves it to the right folder for you.
Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.
It already works with PDFs, text, Markdown, and many other file types. Next I’m adding ePub, and later Microsoft Office and iWork support.
If you have messy folders anywhere on your Mac, Fallinorg can help.
I pride myself on being pretty well organized with my digital life, especially files and folders. I’ve been using Hazel (God Knows, since it's beta). Recently, I realized it has become a muscle memory for me to name/rename files, and drop them where they belong while I'm working on or as it happens. This works for me now because I have a weekly routine of digital chores that picks up any slack and missing things that I missed during my days. Compound this with the fact that I have reduced a lot of clutter, minimized things that I’m involved in. That worked. I did away with Hazel since the beginning of 2025 and I didn’t missed it.
However, I’ve been sheepishly and shamefully looking at either an AI-assisted solution to even do away with the last mile cleanups and organization that I do.
Your text above is good enough marketing for me, and your website’s content sealed it. Didn’t even look further. I’m your customer now. And, personally, have always loved supporting other founders/builders building interesting tools and utilities.
Edit: I just realized this is not compatible with Intel Macs which I wanted to use on too. I didn’t read everything on the website, did I?
Suggestion: Please send me an email after successful purchase, so I have a record.
Thanks so much for your thoughtful comment and support, Brajeshwar — it really means a lot.
You’re right, Fallinorg currently only supports Apple Silicon Macs. The main reason is that the M-series chips have neural engines and very high memory bandwidth, which makes the AI models run fast and efficiently. On Intel Macs the performance just isn’t the same, but I do want to explore ways to bring a great experience there too. If you’d prefer a refund in the meantime, just let me know and I’ll send it right away — no worries at all.
Also, thank you for pointing out the email confirmation — I’ll definitely add that.
I noticed you mentioned using Hazel for years and building up muscle memory with rules. Right now, Fallinorg is built around content-based AI classification rather than rules. But rules can give a lot of precision and flexibility. Could you share what kind of rules or workflows you relied on most with Hazel? That would help me understand how people like you used it, and how Fallinorg might evolve to cover those use cases better.
Again, really appreciate your support and feedback.
No Refunds. I’ll use it with a Silicon Mac.
Some of the key uses that I remember with Hazel were;
- Of course, cleaning the Trash, Downloads, and the “tmp” folder to either delete or mark as old for me to attend to during my digital chore sessions.
- Syncing a backup copy of all Work-Related Google Workspace, which is pre-converted to Open File Formats (I use InSync for this.)[1]
- Screenshots older than a set day to be archived into the Pictures Backup folder. They are yearly for now. So, I have almost all screenshots I ever took, since 2022, in their yearly folder (YYYY). Each year is less than 1GB, so I’m fine with the storage.
1. https://www.insynchq.com
This might be what I've been looking for. On the first of every month I have Hazel put everything in ~/Downloads/yyyy-mm (previous month), with the intent to move each file to the correct project/area folder in my actual file structure. But I'm about 1.5 years behind on that...
Have you looked at competitors? If so, what are they? I haven't found anything that does this as elegantly as Fallinorg.
Thanks for sharing, jonpurdy — I know how fast that backlog can build up!
Most tools I’ve seen (like Sparkle) sort by file name, but that only works if names are clear. Fallinorg looks inside the file itself, so it understands what the content is about before sorting. I haven’t found another Mac app doing that.
Curious — if Fallinorg could automatically handle your ~/Downloads/yyyy-mm folders each month, would that take care of the backlog for you?
It definitely would. Trying it out and not able to use it yet due to the main blocker: need custom categories.
Thanks Jon, Custom categories are available starting with version 3.0 beta. To add one, open Fallinorg Settings → Add New Category. Then enter a name, description with keywords or sample sentences, and make sure the destination folder is set correctly.
Could you please check in the About section which version of the app you’re running?
This is perfect for cleaning out my Downloads folder and adhering to the Johnny Decimal system (as a first pass, anyway). Neat!
Glad it looks useful! Downloads, Desktop folders get messy fast, so it’s perfect for a first clean-up.
How do you usually decide where each file goes in your Johnny Decimal system? I’d love to hear your workflow. Thank you :)
I'm working on a new unconventional form of computing called "temporal computing" - as both a PhD and as a fledgling business. The idea is to use delays in time (It's called interval modulation) as the data. I have a video explainer on YouTube https://youtu.be/rXbzJxThgig?si=FYMleAgZ0GMNEqk9. It's a long road building your own computational model and I'm currently looking at Turing completeness, and models of multiplication.
Well, that's certainly an interesting way to save energy in a logic circuit. The problem I see is that you're going to be able to have to save the value in an analog form at some point to do anything other that single bit math.
Perhaps looking at using each transition in a circuit as a bit, instead of level, could be useful as a power saving strategy that could be compatible with existing VLSI fabrication?
Full-time indie dev breathing life into next-gen terminals [0]. This is my lifelong career ambition.
If you can't afford early access, please email me and I'll grant you a free copy: I need all the feedback I can get!
[0] https://terminal.click
As someone who's curious (I see lots of room for improvement in terminals!), I can't tell what this does from the website, other than the ability to load and view 3d models.
Ah right, that’s just the “wow factor” hook. If you scroll down a smidge you’ll see a 3-minute video trailer.
The Media page also has a 15-minute demo comparing Terminal Click against suckless.
Of course I just need to do a better job telling you what we’re all about without the need to watch videos.
This isn't really the "wow factor" hook you're expecting. It's very confusing and doesn't at all show what it is.
After watching the video where you explain it, I understand and am much more interested in it.
Your URL has 2 "l" in click. Your marketing team should fix that ;)
Dang, thank you!
Nice work! so much cool stuff happening in terminals these days
I launched two apps for visionOS 26 this month:
Metaballs: Spatial, which is a really fun interactive sculpting app. Brand new app. Fast-follow update this week adds USDZ and STL export! https://apps.apple.com/us/app/metaballs/id6748781900
Vibescape: an immersive meditation app. This one is currently featured at the top of the App Store, yay! Launched as a day one app on Vision Pro, new update has what I think is the best immersive environment I've made yet that comes alive with music: https://apps.apple.com/us/app/vibescape/id6476827678
I'm also working on the next episode of Ice Moon — a YouTube series I'm doing on how to build immersive environments for Apple Vision Pro: https://youtube.com/playlist?list=PLHA_sJmXyiktWkqLnHEUj1k5h...
I have made a Bürgeramt appointment finder. It was down for a few weeks after the city of Berlin changed its anti-bot measures. I just released an updated version that works again: https://allaboutberlin.com/tools/appointment-finder
My citizenship wait times page (https://allaboutberlin.com/guides/citizenship-wait-times) has also gotten enough feedback to be useful since its release last month. I'd like to make it more useful with better visualisations.
Now I'm working on another iteration of my health insurance calculator (https://allaboutberlin.com/tools/health-insurance-calculator). It's kind of a big deal both because it's a huge financial decision for recent immigrants, and because it funds a big chunk of all the free stuff I'm putting out. This is especially important with ChatGPT and AI summaries halving my traffic. This iteration will recommend health insurance combinations that work for a visa application and for a long-term stay in Germany. It will provide far better explanations.
At the same time, I'm testing a new insurance broker with far shorter response times, so people can directly ask an expert to help them choose. They're reachable via Whatsapp, and that made a huge difference in how people get advice. It worked so well that I want to do the same for other topics. I'm already talking with an immigration lawyer who's interested.
I'm working on Macscope (https://macscope.app), a better Cmd+Tab for macOS. I built it because macOS window management feels slow compared to the keyboard-driven speed of a terminal or code editor.
It augments your existing muscle memory: a quick tap of a shortcut switches apps like normal, but holding it opens a powerful interface with features like:
Unified Search: Instantly find any window, app, or browser tab.
Scopes: Save and restore entire window layouts for different projects (perfect for after you unplug a monitor).
Placement Modes: Snap windows to screen halves as you switch to them.
The goal is to make the OS feel as fast as my other tools. I'm always looking for feedback on how to make window management less frustrating!
reminds me of https://contexts.co/
Working on a personal recruiter / talent agent for my smartest dev/product/design friends (and theirs) https://www.hedgy.works
Key problems we're solving:
- Everyone wants to be doing meaningful, fun work that feels like their "life's work". Few feel like they are.
- In recruiting, the AI spam problem is real and only getting worse, essentially killing the cold application pipeline. You need a referral.
- Optimizing your career feels like annoying politicking for a lot of the most talented folks who just want to focus on building cool stuff. But, as an employee, if you don't test the market (e.g. take a recruiter conversation) from time to time, your comp can really stagnate.
I built a free & open-source invoice generator: https://easyinvoicepdf.com/?template=stripe
- No sign-up, works entirely in-browser
- Live PDF preview + instant download
- VAT support (EU-friendly)
- Shareable invoice links
- Multi-language (10+) & multi-currency
- Multiple templates (incl. Stripe-style)
- Mobile-friendly
GitHub: https://github.com/VladSez/easy-invoice-pdf
Would love feedback, contributions, or ideas for other templates/features!
How are you planning to generate revenue? My concern will fully free services is that they often don't exist after 3-4 years. Then I have to find another invoice generator. Sticking to WaveApps for now, but this is looking great actually and I'd consider using it.
It’s completely open-source, so it’s easy to fork and self-host if you want to avoid lock-in. I originally built it for myself and don’t have plans to monetize it. Even if I do in the future, the current version will always stay free and without sign-up. Any monetization would come as a separate pro version with extra features, not by removing what’s already available =)
Github: https://github.com/VladSez/easy-invoice-pdf
I left my job to work on my side project (MCP-B: https://news.ycombinator.com/item?id=44515403) full time. I set out with the goal of making the ability to vibecode a webMCP server for your website and inject it via userscript.
While building that, I basically wrote a modern version of Tampermonkey with its own marketplace built in. So you can vibe code any userscript and publish it to the marketplace all within the extension.
The automation stuff is still the core value-prop, but this is a fun bonus feature while I work on solidifying the automation features.
I'm writing a HN post for it. Excited to show everyone in a couple weeks here.
I'm finally organising 20 years of voice notes. Some were quite outdated - I probably no longer need the mozzarella cheese I reminded myself to buy in early 2008.
To organize them, I'm writing a Python Qt application with Claude Code. It started off as vibe coding, but I'm now developing it using processes very similar to those I would use when managing software teams. I've picked up a lot of good tips about that here on HN. I've got Whisper, and fallback online services, transcribing the audio and summarizing it and adding tags. After much UI experimentation, I've landed on something that looks not unlike an email client, with tags in the left pane, a center pane which lists transcriptions and notes about each audio file, and a right pane with more detailed information about the selected audio file.
Next step is to serve it all as a model context protocol server - I need to pick an agent.
this is really neat.
I've been building https://resolver.one - a DNS server that returns GeoIP data as TXT records. Query an IP directly as the hostname (e.g. dig TXT 8.8.8.8.rslvr.one) and get back country, ASN, etc.
Always been fascinated by repurposing established protocols for unintended uses - DNS is everywhere, passes through firewalls, and has built-in caching. Seemed like a fun way to deliver location data without HTTP APIs.
Super niche, definitely a bit odd, but that's the appeal.
Neat idea, even if it doesn't end up going anywhere.
Out of curiosity, are you able to share what your source of data is? Isn't GeoIP data typically licensed?
I work for IPinfo, focusing on data adoption and supporting the wider use of our free services.
The dataset the user is accessing (IPinfo Lite) is licensed under CC-BY-SA 4.0 and does not come with an End User License Agreement (EULA).
Most free IP geolocation databases in the market do include restrictive EULAs. These usually require each individual user to register, obtain their own copy of the database, and limit usage to themselves only. In many cases, sharing the data or keys outside of the original intended scope is considered a violation of license agreement. Because of these restrictions, some providers also offer paid redistribution licenses, which can be expensive and typically targeted at enterprises.
Our approach is different. By licensing IPinfo Lite under CC-BY-SA 4.0 WITHOUT an EULA, we allow anyone to share or redistribute the data freely, as long as proper attribution is given. The goal is twofold:
Some large open-source projects, major global enterprises, and governement institutes are already using IPinfo Lite right now.Data source is IPinfo Lite MMDB file, which seems to be offered freely without restrictions. I'd love to offer comprehensive GeoIP attributes but I'm afraid to even ask how much the DB download of that costs... I'm working on supporting new data sets now like security CVEs, shodan integration, etc.
IP2Location LITE has free data on ZIP code and timezone for enrichment. You can consider it too.
Continuing to do a lot of historical review of early AI stuff. Just finished the Semantic Information Processing[1] book edited by Marvin Minsky, and now I'm reading Volume 1 of the Parallel Distributed Processing[2 book by Rumelhart and McClelland. After that, I have Principles of Semantic Networks[3] by John F. Sowa queued up.
Along with all of that, still working on a lot of stuff using Jason[4] / AgentSpeak[5]. I created a fork[6] of Jason that is meant to be easier to integrate with Spring Boot, and to take more of a "run headless on a server" approach, which meant taking out references to a Swing based in-process logging/management tool. In place of that, I'm implementing a JMX based management interface, and recently I've started to work on replacing the old Swing app with a JavaFX app that can connect using JMX Remoting.

I love this! If you want to do a short book club or do a review after each book, I'm very down!
It's funny you say that. I already do run a weekly "book club" group, but it's at work at my $dayjob employer. And, for various reasons, we've drifted away from the book focus and turned into a more presentation/discussion oriented group. But I still love to read physical books, and wouldn't be opposed to trying to come up with something to structure some discussion around some of these "outside of work" readings that I do.
If you want, drop me and email (prhodes@fogbeam.com) and maybe we can set something up.
I miss Minsky. Loved his books!
I'm working on Blobcache. https://github.com/blobcache/blobcache
Blobcache is content addressed storage, available over the network. Blobcache allow nodes to securely produce and consume storage. Configuration in similar to SSH, drop a public key in the configuration, and you're done. Blobcache is a universal backend for E2E encrypted applications.
Docs - https://github.com/blobcache/blobcache/blob/master/doc/0.0_B...
I'm also working on Got Version Control https://github.com/gotvc/got
Got uses Blobcache for storing file data.
Got is like Git, if you fixed all the problems with storing large files and directories in Git. There's no "large files provider" to configure separately. All the data for a commit goes to the same place. Got also encrypts all the data you put in it, E2E. If you've run into problems putting your whole home directory in Git, you might have more luck with Got.
Both projects are GPL licensed, FOSS. Contributions welcome.
Trying to reboot an early-middle-aged brain that has succumbed to a terrifying, long-term brain fog that has almost crippled me by ruining my concentration span.
Personal projects, developing a habit of contributing my time to a large open source project (having only ever run my own very small ones), teaching newer users how to use that open source package by answering questions and making little example videos, beginning to repackage my notes on things into blog-publishable writing.
Really anything that will help me use brief moments of concentration span to rebuild my confidence in my own ability. It is like a snail ride through treacle but this is the first month-long span in nearly two years where I don't feel like I am falling apart.

I've been working on a map that shows which neighborhoods in a city are nice/not nice with a short description.
Whenever I visit a new city, just looking at Google Maps is pretty meaningless - it's just a bunch of gray land and streets. I end up looking up Reddit posts for where to go, searching for crime maps, trying to find annotated maps, etc. to get a better idea of where to visit in a city (or even live, like when I had moved to Austin). AI generated scoring and descriptions, while imperfect, have already helped me when visiting SF recently. Early stage, so please help with submitting corrections, if you'd like!
I just checked a few cities I have been to and this seams surprisingly accurate. May I ask how you are collecting this data. Is it through Google reviews or how do you collect this data?
I have a similar problem where I want map-type data, but it's subjective reviews that couldn't go in OSM directly.
Are you using OSM's nodes and relations and such as foreign keys for your own overlay, or just lat/long?
Just using lat/long points for the polygons.
Very cool! I really like the idea, the way I'd develop this further is by having live crimes reporting on it so that you know which streets to avoid , similar to what waze does where people report items
I like the idea! In my opinion (looking at SF) it’s still too low resolution. SF in particular can vary greatly in safety, walkability, etc. even a few blocks over within a neighborhood.
Very cool idea, accurate for London & Bristol.
I'm working on a partition-oriented declarative data build system. The inspiration comes from working with systems like Airflow and AWS step functions, where data orchestration is described explicitly, and the dependency relationships between input and produced data partitions is complex. Put simply, writing orchestration code for this case sucks - the goal of the project is to enable whole data platforms to be made up of jobs that declare their input and output partition deps, so that they can be automatically fulfilled, enabling kubernetes-like continuous reconciliation of desired partitions.
This means, instead of the answer to "how do we produce this output data" being "trigger and pray everything upstream is still working", we can answer with "the system was asked to produce this output data partition and its dependencies were automatically built for it". My hope is that this allows the interface with the system to instead be continuously telling it what partitions we want to exist, and letting it figure out the rest, instead of the byzantine DAGs that get built in airflow/etc.
This comes out of a big feeling that even more recent orchestrators like Prefect, Dagster, etc are still solving the wrong problem, and not internalizing the right complexity.
Very much agree that to this is the direction data orchestration platforms should go towards - the basic DAG creation can be straightforward, depending on how you do the authoring - (parsing SQL is always the wrong answer, but is tempting) - but backfills, code updates, etc are when it starts to get spicy.
I think this is where it gets interesting. With partition dependency propagation, backfills are just “hey this range of partitions should exist”. Or, your “wants” partitions are probably still active, and you can just taint the existing partitions. This invalidates the existing partitions, so the wants trigger builds again, and existing consumers don’t see the tainted partitions as live. I think things actually get a lot simpler when you stop trying to reason about those data relationships manually!
Wow, neat idea!
Is this going to be proprietary or OSS?
Definitely open source!
I’ll be on the lookout for a Show HN!
Testing jig for a traction control system for a locomotive. Microcontroller connected to a DDS waveform generator simulates the sensor that picks wheel speed, various ADCs and DACs read in analog voltages that are compared to determine loss of traction. 1980s analog computing at its finest. If I had a choice I would be doing anything else ;)
Continuing to build https://crucialexams.com/, a platform that helps people prepare for IT certifications like CompTIA, AWS, and Microsoft/Azure. It offers realistic practice tests and study tools. I also have partnered with educators and universities who now offer it to their students and get dashboards to review student progress and identify where they are struggling.
LLMRing
https://llmring.ai
is a unified interface across OpenAI, Anthropic, Google, and Ollama - same code works with all providers.
Use aliases instead of hardcoding model IDs. Your code references "summarizer", and a version-controlled lockfile maps it to the actual model. Switch providers by changing the lockfile, not your code.
Also handles streaming, tool calling, and structured output consistently across providers. Plus a human-curated registry (https://llmring.github.io/registry/) that I (try to) keep updated with current model capabilities and pricing - helpful when choosing models.
An MCP server and client are included, as well as the ability to help you define your aliases/models with an interactive chat.
It's a thin wrapper on top of the downstream providers, so you are talking directly to them. And it also comes with a postgres-backed open source server to store logs, costs, etc.
MIT licensed. I am using it in several projects, but it's probably not ready to be presented in polite society yet.
Working on real-time log visualization platform with wallboard/tv support, initially inspired by Logstalgia:
https://tailstream.io
Launched the initial version a couple of weeks ago and making good progress, trying to share as much of the process as I can on X.
Backend API can be used by any client, but I also built an open source agent in Go that makes setup really easy.
Currently working on a proper log viewer, alerts and visualization improvements.
Please show this to AWS. CloudWatch is such a pain, arcade visuals is what I want, if I have to look at logs.
It's been a while since I've used CloudWatch myself. How would you expect this? IE would you lean more towards having a lambda/firehose that forwards events to to the API (which is [public](https://tailstream.io/docs/api) by the way!) or would you expect some kind of agent / connector to run that automatically pulls the logs from CloudWatch?
I'm working on an audiobook service (currently for myself) that will fill in major missing features for platforms like Audible.
- Ignore AI voiced books
- Show me unread books in series that I have in my library
- Experimenting with better search. I have experience with building semantic search systems and have been highly disappointed with Audible's extremely sub-par search capabilities. I want results that are actually based on books, authors, and narrators that I have already purchased, read, or listened to.
- Get automatic notifications when new books from authors and narrators that I subscribe to become available.
There's at least a few more gripes I want to address, but these are the high priority ones that come to mind right now.
>- Ignore AI voiced books
My biggest issue these days, is that after spending 1000 hours messing around in eleven labs, almost all female american audiobook narrators sound AI generated to me. I feel like as a demographic they must have sold a lot of voice recordings to the platform for analysis. I have DNR'ed a few audiobooks recently due to this.
I am working on PicPickr.
It is a desktop app built with Electron and React. I built to help newlywed couples to quickly sort thousands of wedding photos with a Tinder style swipe UI. It is offline first, fully private, and offers one click export of your selected pictures.
I started building it earlier this year after going through my own wedding photo experience and realizing how overwhelming it can be. I saw my wife dragging and dropping photos from one folder to other and thought there has to be a better way for non-photographer folks.
Right now, I have a working prototype, a landing page live, and I am testing distribution and feedback from early users.

I'm still working on DocSpring (which I launched on HN in 2017 as "FormAPI"). It's a tool where you can drag-and-drop fields onto a PDF to create a template, then post data to our API to generate PDFs. We also support e-signatures and hostable forms.
It's still going well, and I've been making a ton of progress lately by using AI agents. I'm very excited to launch my new homepage and pricing soon, plus some other really cool side projects that I've built.
I'm quite proud of this renaming tool as well: https://docspring.github.io/renamify/
I just finished some new features today and launched v0.5.0. The VS Code extension and MCP server are both really handy. I've been using them for quite a few different renames lately. This is one I did today: https://docspring.github.io/renamify/case-studies/deploy-req...
Going solo on

I'm putting a bunch of security tools / data feeds together as a service. The goal is to help teams and individuals run scans/analysis/security project management for "freemium" (certain number of scans/projects for free each month, haven't locked in on how it'll pan out fully $$ wise).
I want to help lower the technical hurdles to running and maintaining security tools for teams and individuals. There are a ton of great open source tools out there, most people either don't know or don't have the time to do a technical deep dive into each. So I'm adding utilities and tools by the day to the platform.
Likewise, there's a built in expert platform for you to get help on your security problems built into the system. (Currently an expert team consisting of [me]). Longer term, I'm working on some AI plugins to help alert on CVEs custom to you, generate automated scans, and some other fun stuff.

I am working on FastFileLink (https://fastfilelink.com/), yet another file-sharing CLI/app that uses WebRTC for P2P transfer but exposes HTTPS links, making it compatible with browsers and tools like curl/wget.
It's ~90% production-ready. We use it internally to move files between containers and hosts (especially when volumes aren't mounted), and for WFH employees to exchange large files without a relay server. For huge files, there's resumable upload to our infra-backed server — fast global downloads included.
The CLI will also support receiving files via WebRTC, but that feature hasn't been released yet. It is open source (https://github.com/nuwainfo/ffl), but the README hasn't been updated yet and the code is not synced with the latest version (working on these).
Another production-used tool I'm working on is MailTrigger (https://www.mailtrigger.net/) — a programmable SMTP server that turns any email into a message on LINE, Slack, Teams, Telegram, SMS, or basically anything. If your app can send email, it can trigger multi-channel notifications with zero extra code.
Think of it as “SMTP to Anything,” or an email-native IFTTT/Zapier.
It supports JS and WASM for preprocessing, routing, and automation — you can write custom logic, auto-reply with LLM-generated messages, or forward alerts intelligently. We use it for price drop alerts, server health monitoring, and integrations with Jenkins/Sentry to push incidents to our DevOps Telegram channel.
Also experimenting with LLM-assisted rule creation: you can define notification logic in natural language instead of writing code — for example, auto-reply with an LLM-generated joke or handle customer support queries dynamically.
Docs are more complete than the website (which is still evolving), and the pricing page is currently a placeholder. Already running in production for us and a few early adopters.
Working on an automated OSINT tool. OSINT is a tough nut to crack because there is so much one can do and the web is literally infinite. So, this tool can automate browsers, it can call functions in a ReAct loop and make inferences on that. It essentially a combination of an investigator + a tool.
This is a demo for the same: https://drive.google.com/file/d/1foBa7mQOJqXcLsD4xpSen7tXMjR...
I have opensourced the tools I am using in order to get some help in refining them. Check out that project here:

Use it, scan some targets!
I'm working on graph insight, a semantic graph tool for exploring research papers. It extracts keyphrases, builds a 3D graph, and lets you navigate from documents > topics > clusters.
So far: ~28k papers processed, 100k+ topics mapped. Use case: faster literature review, spotting hidden links, and seeing research areas as a connected landscape instead of isolated PDFs. I think this tool applicable for news/media streams too.
Example (Text-to-Speech papers): https://www.reddit.com/r/deeplearning/comments/1nic3ft/3d_se...
I’m curious - would this be useful as a standalone tool for researchers/engineers/other domain areas?
I'm rebuilding OnlineOrNot's frontend to be powered by the public REST API. Doing this both as a means of dogfooding, and adding features to the REST API, that I easily dumped into the private GraphQL API without thinking too hard.
Basically I've realised GraphQL has taken me as far as it can, and I should've gone with REST to start with. That, and after I finish the first milestone (uptime checks + cron job monitors), I'll be able to start building a proper terraform provider, and audit logs.

I'm still working on Danger World (https://danger.world), my casual 2D narrative adventure with turn-based RPG elements. Built in Flame, on top of Flutter for iOS, Android, Windows and MacOS.
We're getting close! It's just a matter of polishing and polishing and polishing, but I'm really excited about how close we are to launch.
Work continues for me on Rad[0]. It's a programming language designed specifically for CLI scripts. I was sick of writing Bash scripts and thought we could do much, much better, so that's the goal with this project. Been working on it for a bit over a year now, and I'm using it every day! Still have many big features in mind, such as commands, I suspect I'm still only at the beginning at this journey!

Working on a dutch voting compass that uses real world motion votings as a way to determine which party fits you best. The Netherlands got an open API for this since last year, so it felt appropriate to start using it.
see https://github.com/van-sprundel/partijgedrag
Top man! Thanks, I went trough the votings to see if the party I was thinking of matched actual voting behaviour in the 2e Kamer. It kinda did, but I was suprised another party matched a bit more.
Since that second party also comes forward in other voting compasses I might be more inclined now to vote them instead.
Super goed idee! Ik zie dat de titels/bronlink soms niet overeenkomen met het kernverzoek en beschrijving eronder, daar gaat iets niet goed. Misschien ligt dat aan de open data.
I'm working on Pruno (https://pruno.dev/), it's similar to Dependabot/Renovate bot but it removes dependencies instead.
My team suffers from dependency creep. As soon as your system grows, the number of dependencies skyrockets. In Python/Javascript projects it's especially hard to determine which dependencies are not used anymore.
Pruno saves time for your team by automating this work. It's still WIP, but I'd like to get feedback. How are you dealing with your dependencies?
I've been contributing to a project called Folk computer[1]. It's focused on creating a physical medium for computing (think printing out a program, which is then tracked by the computer. There's some really cool spatial interaction that happens). Folk v2 is currently in development, so I've been digging into the guts of the datalog-like engine. It's been a lot of fun to pick up C and see it applied to a project I can directly interact with!

I recently released JazzEar, an iOS app for ear training. Specifically focuses on improving recognition of chord progressions you would hear in jazz standards.
https://jazzear.com/
Now I'm working on a smaller app for jazz musicians to manage their tune list and act as a tool to help practice and review tunes. I wanted this app to tell me what tunes on my list I haven't played in a while (and might forget), or try different keys or exercises on the tune and track what I found difficult.
Building SupaBird.io - reverse-engineering viral X content so you don't have to guess what works.
Here's the catch: most creators study top accounts but can't replicate their success. They miss the patterns.
Analyzed 1M+ tweets from top performers and built AI that doesn't just copy - it adapts their winning frameworks to your voice and niche.
One user went from inconsistent posting to systematic growth. The content quality jumped. The engagement followed.

Trying to re-legalize "neighborhood commercial" by right in the city I live in. Things like corner stores or small barber shops or coffee shops or converted restaurants. ACUs or Accessory Commercial Units, home conversions... different ways of doing it.
Great. I assume you live in the US ? Your urban planning law are atrocious. In countries like thailand for instance it's very common to have a shop in the house. Things go nicely and it's more lively. Good luck, that a good project at the root of so many issues
If you have a shop in a house in Thailand and a crazy person decides he likes the shop and stays in front of it all day yelling, in Thailand, the people in the house call the police, who make the crazy person leave. In the US, every person, crazy or not, has Freedoms and Rights, and the police won't do anything to help the people in the house because it would be wrong according the the US way of thinking to curtail the Rights and Freedoms of the crazy person (who is yelling all day near the shop, which is very near the house).
Consequently, owners of houses in the US try to make it as boring as possible and as useless as possible for any crazy person, homeless person or group of teenagers to hang around near the house. One way they do this is to make sure the house is surrounded only by other houses, trees, parking spaces and roads (and there is not anything as useful or interesting as a shop in easy walking distance).
This is a bit of an exaggeration, but it is directionally accurate.
No, it's mostly just car-brain where people think that cities should be designed around cars cars and cars, and then if there's room left over, maybe some shops and homes.
So they worry about a neighborhood shop taking up the precious, precious parking spots or causing 'traffic!' even if in reality it reduces it because people have something close by their home they could even walk or bike to.
So the root problem is not the American commitment to rights and freedoms (especially for the disadvantaged) that Americans discuss constantly -- often in heated, emotional or abstract terms and sometimes in frankly ideological terms. According to you the root problem is an irrational and destructive commitment to automobiles, which (at least after the 1960s) Americans talk about much less than they talk about rights and freedoms -- and when they talk about them, they talk mostly in pragmatic terms, e.g., miles per gallon, turning radius, maintenance costs and space for car seats for children.
I live in a city of 100K people, where there really aren't that many visible people with mental health issues or drug problems. I also go to a lot of city council meetings and hearings and observe local social media.
It's the cars.
Do people often yell at stores in commercial settings?
Any chance you've documented your experiences?
There's some writing up at https://bendyimby.com/ but it's not really 'documenting my experiences'. What would you like to see/know? Feel free to write me an email, I'm more than happy to chat about it!
I'll start with that link which - at a glance - looks great and covers the process of working through local government.
I admit this is mostly and idle curiosity for me but it's a good cause and hope others see your work.
Working with local government is different everywhere and there are probably different groups that are more or less effective in different places. As above, happy to give you some basics if you want to write.
I'm building a tool shed completely from scratch. Actually doing woodwork (ok ok it was also an excuse to get a nice nail gun) and seeing something tangible at the end of your efforts is surprisingly nice if your day job is entirely virtual.

Our patent-pending neurostimulation builds on over a decade of research in slow-wave enhancement, and more than 50+ published peer-reviewed papers.
Today we're building our last 3D printed unit. In October we start our first tooling run.
The first thing I need to see is what it can achieve.
30% increase in slow-wave activity. 15% decrease in early night cortisol 14.5% increase in HRV during stimulation
It's all in the research.
Should be on the landing page.
Indeed. The landing page looks like full-on quackery. All the (tm)s and "patent-pending" tags are red flags basically.
We used to, until we have regulatory approvals, we unfortunately have to do the more handwavy stuff.
Encoding / decoding hidden messages in LLM output.
https://github.com/sutt/innocuous
The traditional use-case is steganography ("hidden writing"). But I see more potential applications than just for spy stuff.
I'm using this project as a case study for writing CS-oriented codebases and keeping track of every prompt and generated code line in a markdown file: https://github.com/sutt/innocuous/blob/master/docs/dev-summa...
My favorite pattern I've found is to write encode implementations manually, and then AI pretty easily is able to follow that logic and translate it into a decode function.
Most of our jobs consist of working with tools. Yet it’s very hard to get insights into which tools are required most, are growing in your area, etc. So I decided to keep track of tools and technologies mentioned in the data space by keeping track of job openings for the last two years. Now I’ve opened up that data set. Here’s an analysis for jobs per data warehouse: https://selectfrom.work/insights/data_warehouses
Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer
Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things.
Next addition will be to add health inspection data from countries that have that in open datasets or APIs, so if anyone know of that I'd be appreciative of hints (know of UK, Norway and might have found for France).
Just checked out NYC and saw that most of the venues have abysmal ratings (e.g. 3.02/10). Am I reading the numbers wrong?
The number and the fire icons are popularity ratings, and shouldn't be expected to say a lot about quality. That value is derived from a set of automated signals that can be considered proxies for popularity. For most markets we typically see a couple of stand outs, and "the rest". One major flaw is also that we don't know venue capacity, so this probably does bias towards bigger venues
For NYC specifically it could be many factors playing in.. Perhaps we don't really have the right venues listed? Maybe the city favors small neighborhood bars over bigger destinations? etc..
I just recently added the number behind the icons, but one of my concerns was that it would then be interpreted as a review rating. Might re-consider the UX of this now. Thanks for feedback!
Would be great to know which pubs have gluten free beer. I recently became gluten intolerant, and it's ended my 40 year beer career!
That sucks. I see the value in that, and I can add a tag for it. Imagine maintaining a consistent status for that automatically would be hard though. So the meaning of such a tag would likely become "They had at least one gluten free option at one time".
For venues publishing their drafts, cans or bottles publicly it could be possible to create some confidence interval if we scrape the data and keep history of it.
Thanks for checking it out and leaving a suggestion for improvement!
They are becoming more common, as it's very simple to make them GF- you can simply add an enzyme that eats up the gluten. Bristol Beer Factory's whole range is GF and very tasty (my local brewery).
I'm trying to incentivize people to build IRL communities instead of AI-related apps because the demand for human interaction FAR outweighs the supply. My platform (https://onthe.town), is basically Shopify for social experience clubs. Anyone can start a club and create events based around bringing random people together IRL based on shared interests. You get your own website and infra that handles signups, payments, and matching.
It's largely based on platform-izing the extremely popular Timeleft app that simply matches 6 random people for dinner. With onthe.town, anyone can create a Timeleft-like app around any concept they're interested in. Some clubs people have created include a golf club (get matched with 3 other people to play golf with), a vinyl record sharing club, a lunch club for biotech networking, and a club to meet other parents for dinner.
There was a startup in my region who got popular with the simple idea of having a website/service that manages simple events, like talks, presentations etc.
I think it started with mostly students using it because there used to be a lot of university-related events like these, and eventually they’ve become the standard platform for that, at least in the State. It was all pretty simple, it managed payment etc. and you’d get a QR code by email or in the app that could be scanned in the entrance.
Love the idea. From the FAQ section on the website:
> Organizers can keep a portion of sign-up or event fees
Isn't this a given? Don't event organisers expect to keep the entire sign-up fee for themselves when they host an event? The website banner reads:
> Build an IRL community. Get paid for it.
I was under the impression that onthe.town will pay the organisers from their own pocket for organising the event, but that does not seem to be true.
Really appreciate the feedback. The idea right now is that you set up a club and attendees pay a small amount for each event, and then we take a small (~10%) fee for selecting the venues, doing the matching, and handling payments for you.
But I do love your idea and it's something I'm pursuing. We are matching people to meet at venues (restaurants, golf courses, etc) and it makes sense for venues to pay to be selected. That money would go to organizers and the events could be free. It's just a harder B2B problem to convince companies to sponsor communities.
Ultimately, clubs will have the flexibility to be run in multiple ways - from free, to business-sponsored or attendee-funded, to even onthetown-sponsored as you suggest.
I’m building a text editor inspired by ed, but instead of editing files on disk, it edits live network flows. In this model, files don’t exist as static objects—they exist in motion.
Creating a file generates a self-sustaining pattern of packets circulating through the network, and editing it changes the flow itself. Multiple users can edit the same file simultaneously, because the file isn’t tied to any machine—it’s in the network.
The interface is familiar if you’ve used ed, with commands like append, delete, and substitute, but behind the scenes it’s all live traffic. You can even discover existing flows and jump into them in real time.
It’s a Linux proof-of-concept using raw sockets, and the goal is to explore what files could be if we thought of them as living, circulating processes rather than static storage.

I'm doing a PL based on SQLite's VM.
I first tried to expose the VDBE to public usage, so it could be easier to right hand-made bytecodes, but it would require an effort that I'm not quite have to a side project. So instead I'm extending SQLite's parser to accept things like `let <var> = <expr>`, and functions. Alongside, I'm doing a "standard library" so you could build web servers and stuff.
The thing I'm struggling with is managing execution state. I have the idea of doing transactional functions using function coloring (e.g async functions), so each function call opens a new savepoint, and the user could rollback a particular function call in case it got wrong. I put the deadline to be 31 October, if I manage to get this on time I'll post here on HN :)
I’ve been working on a custom RTOS for Cortex-M for the past 10 years: https://github.com/raphui/rnk
It started as a way to learn RTOS internals, and over time it has grown into something with lots of nice features. I’m even using it in a dirtbike anti-theft tracker I am building.
Also, this month I did a weekend challenge to build an embedded software parameter DSL and compiler. Its goal is to let firmware developers define configuration values, thresholds, constants, and other application-level parameters in a structured, human-readable format, and compile them into binary data that the firmware can directly use.
https://github.com/raphui/epc
Happy to get any feedback :)
I'm working on top down shooter for the browser (co-op to come) https://www.demoncleaners.com/
This uses phaser, standard web tech, wasm (built from Go engine running on server).
Trying to build browser games that feel more like Steam games.
Really cool, but please consider adding support for using the arrow keys and/or changing the keybindings. Right now it's unplayable unless you're using a QWERTY layout.
Its on the list, thanks!
Impressive! Feels really responsive. I feel the controls are a little unusual though: WASD corresponds to actual map orientation rather than to where the character is facing. I find it confusing when playing together with a mouse, where I would expect I can hold W to move forward while using the mouse to control the character's orientation and direction.
The initial implementation actually used that approach - but I got some complaints from people saying it felt weird and I changed it. That was a long time ago during prototyping though - might change it back and see how it feels now (or just add an option). Thanks for the feedback.
IIRC Factorio supports both modes as an option.
It's awesome! Well done!

I'm working on Listening Facts[0], a music habits visualization tool based on your top tracks. Inspired by Receiptify and every day nutrition facts labels[1].
It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integration.
I posted about it[3] on Last FM's subreddit and I was pleasantly surprised to see that a lot of people shared their labels on the comments and seemed to like it.
I'm currently working on language detection, I think it'd be cool to get a language breakdown of the songs you listen to and for that to be part of the displayed items within the label. Something along the lines of EN- 80%, ES- 15%, FR - 5%
I've also tried getting Adsense on the website but I keep getting denied on "Low Content Value" grounds. I tried some alternatives but the quality of their ads was ridiculous (stuff like "your device has a virus, click here to clean it up")

I am working on Sweet Shop.
https://sweetshop.app
It's a digital comic book store. Letterboxd with a buy button. It's really fun. We've got a lot of great publishers signed, and a great team. It's such a thrill to work in a space where people work their ass off to create art, in spite of the fact that the rewards are minimal. Our job, we feel, is to make them more money to make more art.
NativePHP & Bifrost
https://nativephp.com
https://bifrost.nativephp.com
A two-man team, we're enabling PHP developers to get into mobile app development as easily as possible - no need to learn new languages, no new skills, just a few commands and away you go.
NativePHP is the library. Bifrost is the build and release service, getting apps into the stores faster than anything else.
This month we're planning to release the first fully open source version of the Mobile package.
How's it going?
We've sold over 2,000 licenses since May. We built Bifrost over the summer and it already has almost 300 monthly subscribers.
We just gave away another 1,000 licenses to the African PHP community.

I'm making a visual explainer site for PyTorch functions:
https://whytorch.org/
A great example of how it works is http://whytorch.org/torch.amax/
Clicking items in the tensors explains where they came from and where they are used in the output. The input tensors can be modified too.
It's a one-man side project that's been half building the site framework, and half re-implementing pytorch functions in javascript. Plenty more functions to go, but hopefully people can already find it useful. I'm planning on doing a Show HN once I've added ~10 more functions.
Posting this from a throwaway account because my main account is locked due to `noprocrast`!
This looks neat. Great idea!
Perhaps `dot`, `cross` etc might be useful additions.
I've just added the dot, cross, and Kronecker products - thanks for the suggestion!

Solo-building this project for some time, going to launch the first version in a week or so!
https://elmo.dev - a tool that automatically builds a searchable knowledge base around your project based on your conversation with coding tools.
It works automatically and doesn't require your attention. To build KB it uses same tool as you (claude/codex/gemini) so it uses the same quota and you don't have to pay additionally for the AI running it.
The result is ./elmodocs directory in the root of your project. You can reference CLAUDE.md/AGENTS.md/GEMINI.md to this directory or directly include the whole directory or its parts into the coding context.
I'm working on 2 projects right now:
1. Fluxmail - https://fluxmail.ai
Fluxmail is an AI-powered email app that helps you get done with email faster. I think there's a significant opportunity for AI to change the way we use email, and I'm experimenting with ways to improve the status quo. I'd love to hear what features you'd like to see in such an app!
2. ExploreJobs.ai - https://explorejobs.ai
This is a job board for AI jobs and companies. The job market in AI is pretty hot right now, and there are a lot of cool AI companies out there. I'm hoping to connect job seekers with fast-growing AI companies.
I am launching (tomorrow) a service that helps builders and businesses fix their vibe coded apps and get them production-ready and integrated into their organization:

I am just working through a couple of bugs for my location parsing library for Java called location4j.
https://github.com/tomaytotomato/location4j
It uses NLP to try and understand and resolve a location from some free text to either a City, State or Country.
e.g.
"NY USA" -> "New York, United States of America"
"LOS ANGELES, CA" --> "Los Angeles, California, United States of America"
I have some interesting bugs with collisions in concepts e.g.
- Mexico is a country but you can also call Mexico city
- New York as a city exists in multiple places and is also a state in America
Got some interesting issues with

https://sumostats.com
a fun side project to track Sumo stats.
Every two months there’s a 15-day tournament where 670 rikishi(sumo wrestler) fighting ~160 matches each day. I’m recording all the results and kimarite (winning moves) into a browsable database with charts and videos.
Recently I have been using Gemini to process and edit the daily match videos. It works surprising well. It can detect the start/end of each bout, recognise the wrestlers and assign the correct rikishi id to them.
Still early, but if you want to get into Sumo feel free to join! Its fun to watch and the matches are quick!
Sumo fan here, this is cool. UI is great. I assume you know about sumodb? I don't say that to discourage you, but people are tracking stats.
Since you are good at UI, here's something I would really like: a Natto-style page for each bout that I can manually page through as I watch the basho. Since Natto is underground, I have to watch the basho on NHK or Abema or via Kintamayama - all fine, but I miss the Natto graphics. If you could do that in a way that I could tap through each match, I'd use it every day of the basho and I think so would everyone on r/sumo.
BTW if you don't know what I'm talking about, reach out and I will explain.
Sumodb is great and still better in many ways!
I was testing something like this with https://sumostats.com/live (a second-screen style page, so you can quickly look up the current match and it follows along live).
But I think I know what you mean... I'll check out Natto graphics again (haven't seen it in a while) and will try make something up for next basho!
Given that people bet on sumo, wouldn't people pay a lot of money for your stats?
Haven't met anyone who bets on sumo so I don't know. The stats are out there, so I don't think its worth anything more than a bit of ui convenience
We're building a monster trainer where you can actually teach your monster moves. Think like Pokémon the anime, but for real: https://youtu.be/ThOCM9TK_yo?feature=shared
Behind the scenes, we're doing real time code gen to power the monsters!
Would love feedback!
ok this is really cool. do you do procedural animations as well or it's still animated library of moves you blend?
No procedural animations yet, but soon we want to get there. We also want to do procedural VFX. There is a lot of meat in there!
OOh I have a great connect for VFX if you need a sound engineer

Mostly organizing my dotfiles across Windows, macOS, Linux and BSD, however, I have really fallen for Ansible. I discovered at work awhile back, but was able to grok how to make and run a playbook, and I've been hooked since. It also finally allowed me to click the difference between Imperative and Declarative programming!
Careful, not all ansible is declarative or idempotent. Lots of foot guns exist, still a valuable tool

I'm working on Knuckledragger, a proof assistant shallowly based upon z3py https://github.com/philzook58/knuckledragger
Yesterday I proved the infinitude of primes, which I was pretty happy with. https://www.philipzucker.com/knuckle_primes/ A trivial theorem in the scheme of things, but one for which z3 certainly can't do it on it's own.
In the recent years, I discovered the joys of self hosting. What started with a single Plex server for my movie collection became a growing suite of open source applications that became my own personal cloud.
At the same time, I quickly ran into several of the limitations involved, ip addresses fluctuation, limited up speed on residential internet, electricity problems, you name it.
I didn't want to pay the crazy prices required for a dedicated server on AWS, and my storage needs were much greater that I was willing to pay for.
So I started a local business that allows you to run your own mac mini and access it with a dedicated ip for whatever purpose you would like: https://www.minimahost.com/
I'm hoping that over time I can grow it to a point that it could replace my software day job.
Oh, and I am about 3 years into an online mobile battle game. Hoping to publish in the next year or so.
I’ve been building Flare (https://www.getflare.app/), an app for people with chronic skin conditions (eczema, rosacea, etc).
It lets you log symptoms and triggers, but the bigger vision is being able to discover patterns, ask questions about your own data, etc.
Being able to answer questions like “Do my flare-ups correlate with stress?” or “What foods make things worse?” backed with personalized data has been helpful with my own flares.
Still early, but curious to hear thoughts from folks!
I built an alternative to the Typescript package "neverthrow" called "no-exceptions"
I found neverthrow's api to be not very ergonomic so I built my own little version.

Serious question, not dismissing any of your work but why implement it yourself when there's plenty of such implementations in TS land already.
fp-ts has an Either type e.g. but there's plenty of such libraries.
https://gcanti.github.io/fp-ts/modules/Either.ts.html
Hi, no worries, I understand your question.
I thought that most of the use cases for such a library could be boiled down to a single function that can wrap throwable pieces of code and convert their result to a Result type and that's exactly what I implemented.
I also wanted minimal amount of methods for the Result variant classes and delightful method names so I tried to do that and I'm happy with the results! (no pun intended)
It's just a little side project, not much thought has been put inside of it except the core idea behind it that I just explained.
The post says why.
I am working on LakyAI, https://lakyai.com, marketing platform to build brands. It's a mix of WordPress and Buffer in a way. Great for people that want to blog but also get some distribution and social media help. If you want to try it, please DM me at x.com/strzibnyj
I’ve been working on [Vizzly](https://vizzly.dev) -- my attempt to make visual quality part of the development workflow, not an after-the-fact testing phase.
Most visual testing tools spin up a recreated environment (copy the DOM + assets, render in their own infra) and then compare diffs. The problem is: that’s not what your users actually see. You end up debugging rendering quirks in their browser instead of yours. I wrote about it here if you’re curious: [Why Visual Testing Needed a Different Approach.](https://vizzly.dev/blog/why-visual-testing-needed-a-differen...)
Vizzly flips that around by focusing on developer workflows first:
- Local TDD: vizzly tdd lets you iterate on UI changes locally, instantly, against real screenshots. - Bring your own screenshots: Works with whatever infra you already have (Playwright, Puppeteer, BrowserStack, CI runners, etc.). - Team review: When you push, every commit builds a visual review dashboard with position-based comments, review rules, deep links, etc.
The CLI/SDK are open, you can even use just the local TDD bits without ever touching Vizzly’s hosted service. The goal is to close the developer ↔ designer gap by making visual review a normal part of shipping features, not a separate QA checklist.
Would love feedback from folks who’ve wrestled with visual diffs before. Does this workflow resonate with you, or do you see gaps I should be thinking about?
I'm working on Habitat. It's a free and open source, self-hosted platform for communities to discover and discuss their local area. The plan is for it to be federated.

I have been building https://github.com/zayr0-9/Yggdrasil
It started as a solution to LLM front ends having terrible native branching features. But slowly I realize most of our data will be going through LLM's so Yggdrasil is evolving into a platform which consumes all your LLM queries, while keeping it easy to query and reference.
And now I have begun to realize how detrimental LLM assisted coding can be to someone who starts depending on it too much, so Yggdrasil is a bet in the other direction as compared to mainstream. Instead of agents/AI doing everything I believe human + ai assistance will win in the end.
Yggdrasil has a simple agent called Valkyrie, so they have their place, but that I believe should be the last step, after the developer has discussed and planned thoroughly through our tree interface, Heimdall.
And if someone replaces the dev, they can browse their conversations with the LLM, observe their mind map, what questions they asked, what extra things they considered (branches), the whole thought process easily navigable and visible.
Personally after using Yggdrasil, I feel quite confident in using the LLM, as I can ask all the silly questions I want, without worrying about context pollution. It aligns really well with the natural exploratory tangential thoughts we have when trying to find solutions or learn something.
I’m building TypeQuicker: https://www.typequicker.com
Typing is an extremely underrated skill and especially in the age of LLMs, it is the bottle neck in a lot of cases.
I’ve never been fond of existing typing apps; excessive ads, typing random words, etc so I built my own.
You can practice typing code, use your own text, etc
We have a paid plan for features where you can type natural text that targets your weak points (via SmartPractice) and many others. Other than that, it’s both free to use (and ad-free)
nice!
i open and close parens, brackets and curlies at the same time.
is there a mode/setting to capture this intent?
Hi - thanks for checking it out!:)
Sorry, I’m not sure I follow - do you mean you type: () and then type within them?
exactly.
AFAIK a lot of programmers do this before their editor would auto close them and so its now muscle memory to
(+)+Ctrl+B or (+)+ ←
to finish a statement
That’s great! Going to give it to my kids to try.
Thanks! Any feedback is welcome :)
An AI interface to a point-of-sale (POS) system: https://github.com/paulmooreparks/PosKernel
I'm actually in the middle of a complete redesign of the AI layer, but there is a POC video linked from the GitHub README that demonstrates the interaction I'm going for using an earlier version. The POS is a very bare-bones system where the "kernel," as it were, is implemented in Rust. There's an MCP atop that to allow the AI and UI layers to drive the POS. Stores may be implemented as extensions that plug into the POS kernel, and that's where language, currency, item databases, and such are defined. The AI cashier knows what items are for sale, how to modify items (in a restaurant context), how to translate from other languages, how to interpret what the customer actually wants, and seamlessly lead the customer through a transaction.
The current code is quite ugly and full of a lot of unfortunate hacks, but it was a good education. The new design puts the AI much more in charge, without as much code-level orchestration. I'm applying a lot of my knowledge from the retail POS and self-service checkout domains to this, as well as learning a lot about applying AI to a "legacy" software domain.
Since last year i've been working on something that surprisingly didn't exist before, an app where you can rate sports games.
https://rategame.io/ and on the app stores(I really recommend the app if you want to check it out, especially on a phone)
We've expanded on the concept with rating stadiums, creating lists, voting for player of the game and more as we are trying to become the letterboxd for sports.
wow.. this is cool. what's the endgame? I built a site that logs my lifetime in person attendance along with statcast tracking for homeruns, launch angle and more. wonder if theres some crossover https://baseball.willbaxter.info/
The endgame is to become the ultimate source of truth regarding the quality of a sports game.
Dreaming big with hopes of becoming a household name similar to imdb or letterboxd.
Looking at your site I think you would like to hear that when rating games you can mark a game as 'attended', 'watched' or other categories to show others how you experienced the game or just for your own personal log.
Other than that we are light on classic sports stats and our stats are more focused on the user ratings of the games rather than the game stats.
"Backend APIs, but everything works from the frontend": https://www.skapi.com
This has been my passion project for the past 4 years, and I finally launched it recently. It’s starting to get some real users, which has been incredibly rewarding.
The idea came from my frustration every time I tried to build a web service. No matter which API service or cloud provider I used, designing databases, deploying and managing backend infrastructure always felt too complex and not much fun. So I built a backend API that just works out of the box, directly from your frontend project, with no backend setup or deployment required.
I sometimes wonder if the world really needs another backend API in this new “vibe coding” era. But since everything can be done from the frontend, it also fits naturally with coding agents like Claude Code.
For now, I hope my APIs would help web devs skip the backend headaches and spend more time on the fun part like building the frontend.
A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use.
There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used.
When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.

I’ve been working more on the unit economics of my data union/trust idea (https://wherelabs.info/).
What I’m trying to understand is whether it is viable to pay people ~$5 per week for sharing their location data and demographics based on a 90% share of revenue from sales of data products built on that data. (But without ever selling or exposing individual level data).
https://weexpire.org - An opensource tool for creating emergency notes that can be read by your trusted contacts only after your death or if you are seriously injured.
I would love to read about the psychology of why we may want those notes to be hidden from them before our death/injury.
Not sure you need psychology to figure it out: the notes may contain passwords to your accounts, confessions, and other things you're not comfortable sharing when you're alive.
In my free time I'm starting a new Low Power FM community radio station for the east San Fernando Valley.
www.kpbj.fm
Very nice! Looking forward to when the online stream is available.
Thanks! We're hoping to get the online stream going by the end of the year. We have a _ton_ of programming submissions but its going to be a challenge to get it all scheduled.
I'm building out a new website for it right now too. Hoping to launch that soon.
In June, I shared Marches & Gnats (https://mng.quest), a programming puzzle game (similar to Advent of Code) where you solve challenges using a Turing machine.
Since then:
- I added 13 new quests, from arithmetic basics to Elementary Cellular Automata and Sudoku.
- Rewrote the Turing machine core in Rust, making evaluation much faster and able to handle heavier tasks.
- 102 players have joined, submitting 15000 solutions; 10 players have already solved every quest.
The hardest part turned out to be the storyline. I use ChatGPT to draft outlines. It does it quite well, but shaping them into something with real depth and atmosphere takes far more work than I expected.
Another challenge: since it's a competitive game, players quickly explored the edges of the rules. For example, submitting very long solutions that use transitions as a kind of memory. I love that kind of creativity, but it also undermines the original goal of solving a puzzle as efficiently as possible. So I've spent quite some time balancing mechanics to reward creativity without encouraging loopholes much.
The most fun part, though, is still inventing new puzzles.
Empor.top - https://empor.top the stories of top companies. Highly engaging and readable long form stories (AI generated). Primarily, I made it for myself but in the last 30 days I got >10k hits so I'm contemplating making it a full blown project.
Pretty cool! Are you scraping the data first to pass it to an AI or letting it do the entire thing by itself? Also, if its the latter, are you using a multi-agent framework? Only asking because it seems way too detailed for a single input-output sequence!
I've been working on a tool to add long term memory to various AI tools. It started last year as a small scratch-your-own-itch side project. After using ChatGPT Plus for a month, I went back to TypingMind, my go-to AI client at the time, but I really missed the memory feature and wanted it there. So I made a simple memory plugin for it.
Over time, the project has grown to now support more than 17 platforms, thousands of users, and has been growing organically.
As of most recently a major feature I've been working on is full chat history based memory. Being able to remember and recall every conversation you've ever had across multiple supported AI tools, similar to the reference past conversations feature in various AI apps. This has been pretty intense and fun. Ingesting tens of millions of tokens per user, and doing complex multi-stage RAG on-the-fly across this vast dataset with a tight latency target for UX.
The project is MemoryPlugin: https://www.memoryplugin.com
Another project is a RAG app that's built specifically for books. No "we work with your receipts, and legal documents, instruction manuals, product documentation, lecture transcripts, your dogs novel, the script for a play and everything else possible". I wanted something tailored for books, specifically, non-fiction books. When you try to work everywhere, you can not deliver an amazing experience for any one specific use case. AskLibrary is tailored for non-fiction books, so everything from the answer generation pipelines, to the ingestion pipeline, and various other features are all designed for this specific use case. https://www.asklibrary.ai
I am working on Octelium https://github.com/octelium/octelium a FOSS unified zero trust secure access platform that is flexible enough to operate as a modern zero-config remote access VPN, a Zero Trust Network Access (ZTNA)/BeyondCorp platform, an API/AI/LLM gateway, an infrastructure for MCP gateways and agentic AI architectures/meshes, a PaaS-like platform, ngrok alternative, and even as a homelab infrastructure. It is basically a unified, generic, Kubernetes-like, zero trust architecture (ZTA) for secure access and deployment, that can operate in many human-to-workload, workload-to-workload, and hybrid environments.
I actually did a SHOW HN exactly 3 months ago and received lots of invaluable critique regarding how dense, overwhelming and unreadable the docs and repo README were. I've actually spent a lot of time trying to improve the quality of the docs and README since then. I'd love to receive any feedback, negative included, regarding the current overall quality of the docs and README from whoever is interest in that space.
Can you communicate the value of Octelium in 25 words or less?
A different Internet message board. It's based on two principles: each sentence written must be true, and claims must be easy to verify.
https://truediffs.com
Lately I’ve been telling my friends I’m done. I’ve entered my George Carlin phase. Words don’t seem to mean anything anymore. YouTube titles? Clickbait. News headlines? Clickbait. People say this and that, and in the end it’s nothing like what they promised. And then this... love the idea!
I'm in love with this message board. OP, is there any way I can participate in the project? no need for payment. I just really really love it.
You're the first person to show this much enthusiasm for the project. I'd love your input on how to innovate further and build a community around it.
And it became my landing page. Thank you so damned much.
When I loaded the page, the first thing I saw was some antivax garbage. Is this one of these things where "each sentence must be true" is twisted to the point that every lie becomes a truth?
Can you point out the sentence that was incorrect?
Nice idea!
I’ve been working on a few utility libraries to make it easier to develop web services, basically exporting packages that I find myself using or rewriting often and exporting them as their own modules.
I recently published https://github.com/hxtk/sqlt for SQL query generation with Go templates.
I’m working on https://github.com/hxtk/aip as a collection of libraries giving safe default choices to implement Google’s API improvement proposals in ConnectRPC services. It borrows (with attribution per the license) an unexported implementation of AUP-160 filters from the LuCI project, and I intend to expand it to support data sources other than SQL databases and page tokens, and it also exports an implementation of AIP-161 field masks (which have different semantics compared to standard field masks) and middleware to help with using them for AIP-157 read filtering. I intend to export more middleware that I use frequently, but I don’t know if it’ll live in this module or its own yet.
I built a fantasy football rankings app using claude code, and it has been blowing up in the fantasy football subreddit. Funny enough, it's forcing Yahoo to change their site and improve their layout which ruined all my automation. Surprised how much traffic it's receiving every week just for a better layout.
https://boonerankings.com/
How is it deciding rankings? Is this like a mix of points/projections?
Using a popular analysts rankings
I'm working on something completely different, especially for me. After 9 years as a CTO I'm moving on to coach other tech leaders. I just noticed that I didn't like the doing anymore and I'd much rather work with people for people. My biggest takeaway is that the hardest part of building anything is the human side. Emotional baggage, limiting beliefs, social dynamics. All the startups I was part of didn't take off mostly because of this. Pretty interesting to see how our automatic actions driven by unidentified beliefs drive everything we feel, think, and do. So I guess I'm moving into hacking on humans now for a living. Feels exciting.
I'm still very early in building the website but you can say hi or read more about my approach or story here: https://trueselfcto.com/ I'm always open to chat about just anything, so please feel free to share your thoughts or say hi!
We're building a repairable and sustainable e-bike battery at https://gouach.com :)
That's pretty cool. It's nice to see this exists.
For me, I'll probably send an email later to support to ask (no rush, since it's out of stock anyway), but I was checking for info on compatibility with Yamaha (e.g. my Cross Connect) ebikes. It's not on the compatibility list. They make their own (mid-drive) motors (PW-SE on mine I think) and proprietary batteries. They pulled out of the United States market altogether so getting more batteries from them again is doubtful. (Mine currently charges to ~85% and then throws an error code, but it still works for now.) It is a Yamaha 500Wh36V battery pack on the down tube with 3 wires (I just unscrewed where the battery plugs in to see).
Hi! You're probably in the US, we're "out-of-stock" in the US while we were resuming shipping there, but it should be open again in one week or so :)

I'm working on a little hobby language that compiles to wasm: https://mikeinnes.io/posts/raven/
I've spent the last couple of months porting the compiler from Julia to TypeScript. That's nearly done, so I'm hoping I can post an interactive web demo next month!
I’m writing a Python framework to create Python home automation scripts driving Zigbee2MQTT with as little boilerplate as possible. https://pyziggy.github.io
Me and a few friends are working on a firewall for LLM clients that blocks the lethal trifecta: https://github.com/Edison-Watch/open-edison
The way it works is the user registers / imports MCP (Model Context Protocol) servers they would like to use. All the tools of those servers are imported and then the firewall uses structured LLM calls to decide what types of action the tool performs among:
- read private data (e.g. read a local file or read your emails)
- perform an activity on your behalf (e.g. send an email or update a calendar invite)
- read public data (e.g. search the web)
The idea is that if all 3 types of tool calls are performed in a single context session, the LLM is vulnerable to jailbreak attacks (e.g. reads personal data -> reads poisoned public data with malicious instructions -> LLM gets tricked and posts personal data).
Once all the tools are classified the user can go inside and make any adjustments and then they are given the option to set up the gateway as an MCP server in their LLM client of choice. For each LLM session the gateway keeps track of all tool calls and, in particular, which action types are raised in the session. If a tool call is attempted that raises all action types for a session, it gets blocked and the user gets a notification, which sends them to the firewall UI where they can see the offending tool calls, and decide to either block the most recent one or add the triggering "set" to an allowlist.
Next steps are transitioning from the web UI for the product to a desktop app with a much cleaner and more streamlined UI. We're still working on improving the UX but the backend is solid and we would really like to get some more feedback for it.
Working on a chess / poker hybrid.
There was "choker" back in the day, which I actually never heard about since I wasn't into chess back then. But (1) there was no web version, and (2) it had a specific gameplay that seems too slow for my taste. My version is highly customizable on the setup/rounds/rules, too. From my research, the original was also overrun by bots.
Looking up choker online I found this reddit thread:
> It’s a cool concept, but terrible app design and it’s all just bots you connect with, making it terribly easy to win almost every game
It sounds like this game needs a better AI opponent then? I don’t know anything about this game but something that learned from your gameplay and figured out how to beat you would be very cool.
I already have a better chess engine at different skill levels for 1-player mode. For two human players, I plan to start with sending a link to a friend given there won't be enough random players on the website to find one in real-time.
Working solo on few thins:

This is the biggest marketing effort I've done for those projects in months :)
Like the first one because it's so simple, but you need to add a QR code somewhere: it would make a list more easily shareable. ;-)
Https://KushtyBuckRecords.com Been thinking a lot about tools for modern musicians/artists/producers. Not tools for creating the music but tools for communication. Email subscriber lists, event creation (image and text) combined with ability to generate QR codes and send them with easy to use dashboard, some kind of insights into the QR scans, merchandise (integrations with Shopify), hn style link aggregation around music.. been building it with my son who also becomes my product manager since he the one using the tools. For now a private repo consisting of a rails API and a react TS frontend app. Everyday I come up with some small improvements in my head but alas not enough time in the world. With the day job an all, this is purely a passion project and a way to help my son follow his passion, putting on house music events and DJ/producing. If anyone interested, plz reach out contact@kushtybuckrecords.com
I might be taking a contracted job to help provide AI/ML guidance for a friend's company here soon, but all I really do is use ChatGPT/Claude Code a lot and don't really have explicit AI/ML tool building experience. They know this and mostly just want me for competency and comfort going from 0-1 with a new project, but I'm still pretty nervous! So I'm trying to conjure up some simple ideas to inspire me to learn :)
Currently trying to predict student absenteeism in the future based on historical indicators with synthetic data using basic ML modeling and then using LLMs to generate helpful guidance for relevant parties. Basically letting parents know there's concern and citing leading indicators.
Not sure what I'll do next, but hoping to come up with a few other ideas to put my mind at ease. It's fun having some actual motivation to keep up with the current hype instead of just being a consumer, though!
Tritium, the integrated drafting environment for lawyers: https://tritium.legal/
Rust cross-platform application leveraging egui.
Web preview: https://tritium.legal/preview
That’s really cool. And it almost worked on mobile except I can’t side scroll. Super impressive!
I always wondered what lawyers use for version control. They probably don’t call it that, but they must have a git equivalent in their world, right?
They really should, but nothing so far has taken off like Git. Mostly they just have serial versions of the whole document. It's pretty bad.
I have a lawyer friend who’s complaining about versioning… but she also mentioned that Word is the de facto standard. What I’m trying to say is that this should be a Word addon.
Two side projects, as if 3 kids are not enough!

I'm working on a python library that allows you to put data on GPU as fast as your network/storage allows you to at the hardware limits. No more clunky DataLoaders that are too slow and have inconsistent perf. I achieved stable throughput numbers >8GiB/s (so saturating my PC's nvme SSD), going to test on networked scenarios soon. Works for any python ML library (torch, tensorflow, jax, etc.), both for training/inference, single/multi GPUs on one node (shared/separate queues for DDP), multiple sources of data, seamless transition between training/validation phase (no significant perf drop), arbitrary shape of tensors and lots of data configurations.

WithAudio a one-time payment, desktop text-to-speech app that helps users read better by highlighting text as it's spoken.
Current Challenges:
Technical: It's difficult to consistently parse text from various document formats. The I also wants to expand to more platforms but I know I need to focus on marketing.
Non-technical: The product has seen some success with minimal marketing, but I keep getting distracted by spending too much time on technical work. I know I need to do more for marketing but I keep going to my safe space (my IDE).
I believe in the product but it keeps reminding me how difficult is to get somethig to a polished, finished state for all users. 90% of the project takes 90% of the time and the other 10% takes another 90% of the time.
Appreciate any feedback.

Currently bootstrapping a SaaS side project: https://diplomium.com
Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation.
The bigger picture: Certificates are often the only tangible outcome of a learning experience. By making them verifiable, permanent, and easy to distribute, organizations save admin time while learners get a trustworthy credential.
Status: Running for 2 years, used by schools and training centers in Latin America. Now building AI-powered features for design editing and data extraction from PDFs.
Wow, nice project. May I ask how do you generate images under the hood? Something like browser that does screenshot?
Wonderfull nice looking and clear landing page. Best I have seen in a month. Bravo

I wanted to figure out the simplest, most lightweight abstraction, that unifies static site generation and web server for both HTML, JSON, etc. What I arrived at is ~700 lines of TypeScript:
https://mastrojs.github.io/
In a docs-first approach, before building the framework above, I actually first wrote the following guide where you build a static blog, and implement a to-do list app: once with plain JavaScript, then reactively. Finally, you run a server with a REST API, and learn about caching and different architectures:

I've been working on writing two appendix sections on knowledge distillation and reinforcement learning for Machine Learning for Drug Discovery [1], which were initiated as tangents to expand coverage of material from a few earlier chapters. I hope to also write these appendix sections up as freely available articles (at least in a condensed form). Thankfully, I'll be able to finish the knowledge distillation section this month but, unfortunately, I need to pivot to finishing out chapter 11 to stay on schedule for full publication.

I've been wondering for years if historical magazines/periodicals could ever be transformed into a modern ebook format. PDF doesn't cut it, but most other efforts are unsatisfactory... part of what makes a magazine a magazine is the rich, mixed content. So, for the past few weeks (months?) I've been taking a stab at it with the science fiction pulps. Started with Analog/Astounding, and I was able to re-typeset the cover (with original art), most of the interior, many of the ads, and so on.

I built what I guess is a LinkedIn alternative: https://sifted3.com/blog/building-sifted3
It's less focused on the social, more on the jobs. With a limit on the number of job applications a user can make; sort of like Twitter, for job application count. And mechanisms to provide feedback to users. Basically trying to address a few shortcomings of LinkedIn as I see them (with other mechanisms in the pipeline).
But it has neither any jobs, nor candidates.
I'm not sure what the strategy should be to resolve that. I've tried a few things that haven't worked out yet.
In the last 7 days I implemented a complete XPath 1.0 parser & evaluation system from scratch in C++20. Right now I'm adding support for XPath 2.0.
Codex in the cloud has been leveraged to do 95% of the work and Claude 5%. We've output 10.5K LoC and 774 individual tests to ensure compliance to the spec.
Lately I've been feeling like we're living firmly in the future. This would easily be an 8+ month project on my own not including the tests, yet we're now on track for completion in 10 days. A min. 25x speed increase is a crazy level of productivity for me and it's hard to believe I'm still seeing articles claiming that AI coding isn't productive.
I'd imagine part of it is that there are xpath parsers on github already, so it's not entirely greenfield for the models.
Partially, but I think it's moreso the W3C spec being so thorough and the wealth of samples online. I found that during code review both Codex and Claude would refer back to the specs for certainty on expected outcomes. Their understanding of how to deal with unusual edge cases was also impressive, so it seems they have a lot of baked in knowledge & training of how XPath works and they draw from that.
I am working on my Go UI library called gooey [1] which aims to be a one stop framework to build webview/webview apps in Go and WebASM.
It started out with bindings for the DOM, Web, and Browser APIs, but as of today I now have custom Web Components support (which is a big deal considering Go's type system quirks).
Tomorrow I'm gonna polish some of the UI components and start refactoring my git-evac [2] repo management tool which is the first app using the gooey framework.

> Components are bad for web accessibility (aria- property fatigue).
I've been using web components as a vehicle to automate and auto validate accessibility aspects as much as possible, because I think the only way to truly make things sustainably accessible is to find a way to unburden the developer by either inferring as much as possible or making validation a natural part of development rather than a separate testing cycle that will invariably cause accessibility support to become out of sync.
It sounds like you might have similar concerns. Do you have any insights to share along these lines for Gooey?
The UI components that I wrote initially are just wrappers for the Browser provided input/form elements. As I'm relying on webview/webview to build desktop apps out of it, that also kind of implies WebKitGTK4 on Linux, WebKit on MacOS, and WebView2 (Edge) on Windows.
These work quite nicely together with a screen reader because you don't have to intercept the focus event (or others) that people browsing in caret mode or similar would use to navigate the page.
Additionally I decided to make single page applications using a main and section[data-view] elements so that the HTML and CSS alone is enough to hint screen readers on what's visible and so that there are no javascript codes necessary to tween things around, the JS/WebASM side of things literally just sets a data-view property on the main element.
The whole idea behind gooey and the way it is structured is:
- all states must be serializable in HTML
- Static HTML and CSS makes the page usable (apart from web forms and REST APIs, that's developer provided code)
- Dynamic WebASM on top essentially translates the DOM to be interactive, so that things can be animated based on changing data or streams coming from the backend. All interactivity is rendered directly into the DOM, so that it can be serialized again at all times.
- Communication between Client and Server is JSON or any other Go implemented Marshaller, and using Fetch API behind the scenes.
I decided on purpose to not provide XMLHTTPRequest and other old APIs because I'm relying on WebASM and "modern Browser engines" anyways. This way I kinda force users of gooey to use modern JS from the WebASM context and I save a whole lot of trouble with compatibility issues (and don't get into the unsemantic div fatigue like React does, for example).
Looks great! Wish Go wasm modules were smaller.
The bindings should also work with tinygo's compiler if you're careful with deadlocks (see docs/ERRATA.md).
Haven't tested the typecasting that's required for the components yet though, they might break because of some generics quirks (e.g. Wrap/Unwrap helper methods).
That’s a great name.
I'm working on a site that serves as an alternative to Hacker News. There you will find two relevant options (at least I thought so kkk)
1. A notification system. All posts that are commented on or voted on (positively or negatively) will generate notifications on the site for the owners of the respective posts.
2. Diversity of topics. On Comuniq we're not fixated on a single theme, so users who like topics such as health, politics, entertainment, art, etc. will be able to post there and generate very intelligent debates.
We're not trying to take power away from our monster hn, but rather to provide another option where we can talk about other things we love. Check us out at https://comuniq.xyz

Visualize massive aerial images on the web: https://rasterly.com
I started building Rasterly as a side-project to be able to dynamically visualize drone and satellite imagery of any size. You can calculate and view spectral indexes too!
The goal is to make it really easy for drone surveyors, conservationists, researchers, and so on to share aerial imagery without anyone needing to download anything.
No customers yet. Focusing on improving the performance of the tile server and preprocessing of images, and of course trying to connect with potential users! Struggling to transition into a salesman though.
Jacobin, a JVM for Java 21 written in go
Website: https://jacobin.org
GitHub: https://github.com/platypusguy/jacobin
Cool! How far are you planning to take it? Interpreted mode only? Or do you plan on going the whole HotSpot nine yards with compiling bytecode down to native code?
Sorry for the delay in replying.
We want to complete the interpreter and then decide what to do moving forward. The two principal options (and both might be followed) are 1) performance and 2) a separate UI that connects to Jacobin via Websocket or other protocol and enables display/observation of JVM instructions as they're being executed (and of course many of the other observable events).
The biggest hurdle we've faced is the vast number of native methods called by the HotSpot JVM, which need to be reproduced in go for a go-only JVM. I think we've spent as much time working on the native methods in the various libraries as we have on the JVM proper. By our analysis, the JVM calls a total of 1800 native methods. Many won't be needed by us b/c we use go's garbage collector and we don't implement the security manager (which Oracle is deprecating)--but that still leaves quite a few.
I built this: https://github.com/dvcoolarun/web2pdf — a CLI tool for converting web pages to PDFs, open sourced after adding a bunch of new features.
If anyone’s looking to hire a dev or knows of opportunities, I was recently let go and am actively searching. Would appreciate any leads or feedback!

Still working on https://theretowhere.com, which is a website that makes it easier to find apartments and hotels/airbnbs close to people and activities you care about.
The past couple months have been fun since I've implemented a lot of new highly-requested features into the site's city heatmapping capabilities. One thing I've found motivating is having my own private changelog that shows screenshots of feature requests people have given me, and then dates for when I finally finished those features.
It's easy to forget how much stuff you've built in a month or two, sometimes.
I'm working on a Heroku / Render / Flyio alternative thats free, open source, built on top of Kubernetes for about 2 years now.
I’ve found these services charge way too much per GB of memory (10x more than IaaS providers), but more importantly, offer terrible flexibility. You can’t schedule multiple apps on the same instance, and there aren’t many instance size options.

A Sanskrit transliteration (IAST) editing mode for Emacs, including a dictionary and Devanāgarī rendering: https://github.com/sctb/sanskrit.
Often, when I use generative AI to produce videos, the results are close to what I envision but rarely capture my imagination exactly. Prompting the AI to fix specific details can be a cumbersome and time-consuming process. To address this, I'm developing solutions that make the creative workflow more intuitive. So far, I’ve built an app that allows users to provide visual clues as guides, along with a 3D environment where the camera can be freely manipulated within the generated scene.
The community is moving fast though. Now higgsfield allows using arrows and pointers to edit the video but so far, no one is doing a good camera control visually.
I'm working on Fibre, a tool for secure file uploads for Intercom
https://fibre.framer.website
We use Intercom for support and our customers need to upload sensitive docs (think proof of address, bank statements, etc.). Intercom’s native uploads aren’t a long-term fit for us (100MB/file limits, docs live on Intercom’s infra which screams data privacy issues for us) and we need files to land directly in our own storage.
Still thinking about what to include exactly, but we appear to be on the right path!
https://fooqux.com/ - an experimental tech article aggregator.
For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website.
The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc.
I hope this service might be useful to others as well.
That looks great. Are you aiming to automate the gathering process or let users self-serve by creating their own list of bookmarks (then processing the pages on your side)?
Thanks. For now, I don't have any plans to automate this process. Users simply add articles to the site, as in other aggregators, and can filter content by tags.
What would the ideal process of working with this kind of site look like for you?
I'm not sure, my work and hobbies are niche areas of computer science so I find myself wanting very specific filters. That's probably not a requirement for the typical web stack engineer.

I’ve been working on ZenPocket, a minimalist mindfulness iOS app. https://apps.apple.com/jp/app/zenpocket/id6748869085
It has three main parts: – A simple Zazen (sitting meditation) timer – Zen readings – And the main feature: a chat with an AI Zen teacher, where you can ask anything from Buddhist teachings to handling personal problems.
I built this because I’ve always been drawn to the minimalistic style of Zen. ZenPocket doesn't have notification because I am tired of notification-driven apps myself and wanted something simple and clean. Meditation, I believe, can help solve a lot of stressful problems, and adding readings + an AI teacher helps keep my mind stable.

I got tired of Spotify recommending me the same songs, from the same artists, over and over again.
So I built Riff Radar - it creates playlists from your followed artists' complete discography, and allows you to tailor them in multiple ways. Those playlists are my top listened to. I know, because you can also see your listening statistics (at the mercy of Spotify's API).
The playlists also get updated daily. Think of it as a better version of the daily mixes Spotify creates.
https://riffradar.org/
Good stuff, but I don't use the follow feature on Spotify. Can it use number of plays of songs/artists to make the playlists?
Thanks!
Right now it's not possible, but I'll put it on my list of features to add. Unfortunately though, the play history Spotify provides is very innaccurate and incomplete - so suggestions only based on that would be quite limited :( It's the same issue with the statistics, they are best-effort based.
Having said that, there is another feature you could use: if you have or follow any playlists, you can include artists from them. Make sure to have the `Index Playlist Artists` option (it will get enabled automatically if you follow <100 artists) and tick `Include playlist artists` setting when creating your playlists.
Thanks for the response.
Another question: instead of getting my follows from my Spotify, could it let me type the artists I'm interested in?
I really want to use it (I'm also not happy with Spotify's recommendations), but my follow list is mainly for podcasts. Maybe just letting the user enter the artist names (instead of getting them from Spotify follow lists) would be easier to support?
Not currently, no - I might potentially include it at some point, but I feel like the Spotify UI is better tailored for that, so I'm not sure.
The current functionality revolves around genres, and artists are derived from those selections. There are some additional filters where you can filter down based on album/track release dates, exclude genres or specific artists - but it all comes from your library, not from the whole Spotify pool. It was a deliberate decision, as my gripe was the fact that I have a massive library, and was not listening to its entirety.
You can achieve a somewhat similar functionality by creating a playlist, and adding a single song from any artists you want in that playlist.
As to the following list - the podcast/artists libraries are not the same and you can access them at different places in Spotify. If you click on your profile and go to following you'll only see artists/friends. Moreover they are behind separate APIs/access scopes and I only scrape the aritsts you follow.
If you want give it a go, you might find it useful. You can delete your account at any time - I don't keep any of your data once you delete your account.
Kanji Palace - https://kanjipalace.com
I'm building an app to help people memorize Kanji by turning the characters into vivid, memorable images with accompanying mnemonic stories.
I think AI image and video models have reached a point where they can offer a completely new approach to language learning.
Next, I'm planning to add features that use AI to generate comic strips (using Seedream or Nano Banana), songs (using Suno) and videos (using Veo 3 or Seedance) to make learning Kanji even more engaging.
Landing page needs way more quality examples.
There's one shown in the video (and which appears for 1 second after waiting 5 seconds for it to be generated) and 3 static ones below (two out of which don't really correspond to the text menmonic below the image).
Thanks for your feedback!
I've been busily porting my NES game, Tactus, to Windows, Mac, and Linux as a "native" build. It's been fun to consume my own emulator as middleware, and then lightly modify it to support things like a widescreen view, which the original console definitely cannot do. Here's what that looks like:

Right this second I'm getting the paperwork sorted to start my first business (gulp!) which should then let me get a Steam page set up and start messing around with the Steamworks SDK integrations. Tons more work to do, but it's coming together fast.
Even more exciting, the cartridges are finally working! I can play the game on real hardware. :D It's basically the same game code on both platforms, with the PC build just doing a bit of extra work to signal to its emulator "shell" that it has switched game modes. (This affects the widescreen display.) Real hardware capture here:

Codexes Factory: algorithmic tools to create, operate, distribute, and market entire publishing imprints. This week I am launching my first imprint, Xynapse Traces, with 66 books in the Korean pilsa (筆寫) style. Later in October, Nimble Ultra, devoted to the history and practice of intelligence and espionage. Last week I built a giant collection of 575 imprints that are a shadow superset of the ~540 imprints operated by the Big Five publishing houses (Penguin Random House, the largest has ~300). Teeny weeny tip of the iceberg at NimbleBooks.com.
After leaving active involvement in a still-extant biotech I co-founded in 2020, I'm focusing on some ideas I've kicked around for awhile but didn't have time to work on.
The first is a document search system for over 200,000 high quality OCRed pages from successful CD/DVD-ROM products I developed some years ago, covering the official records of the American Civil War as well as 19th century documents on Native American history. The technology stack involves BaseX for indexed document search, Postgres for user data, Redis for transient session information, and Blazor WASM for the UI. (I coded all of it.) It can be seen at https://allhistory.us (currently desktop oriented.)
After working extensively with Coda (and much less with Notion), and becoming frustrated with its limitations, I decided to work on a considerably more powerful and programmable system to compete with both. No externally viewable progress so far, but soon ...
I'm developing on a new system I assembled, for general development but also to be able to seriously work on local AI - an EPYC 9755 CPU (128 core) on a Supermicro motherboard, 384GB RAM, and an RTX 6000 Pro Max-Q. I also have ideas for some AI products but too early to talk about.

Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI.
I am currently working on a new mode that is more like what played walking around: a few rounds in rapid fire, very little time to think before the next round.
Seems like a really small dictionary. Many/most of my guesses (and Gemini's) don't work.
Yeah, sorry about that, and thanks for the heads up!
I've struggled with the dictionary a few different times. Here's to hoping the 12dicts wordlist 2of12inf is a better choice than my previous ones :D
The new dictionary is live!

I've been working on raytraced lighting in the Bevy game engine, using wgpu's new support for hardware raytracing in WGSL. The initial prototype is launching with the release of Bevy 0.17 tomorrow, but there's still a ton left to improve. Lots of experimenting with shaders and different optimizations.
I wrote a blog post about my initial findings recently: https://jms55.github.io/posts/2025-09-20-solari-bevy-0-17
Side project: https://healthymcp.com
At work we have an MCP that is mostly a proxy to our API and it was a little tricky to get it hooked into our regular CI/CD regression testing so I thought a dedicated service to track MCP server statuses could be useful.
Hacking away at it slowly. So far it has ping monitoring, tool validation, resource checks, SSL and DNS / HTTP header tests
Hoping to get protocol version logging, custom tool-call monitoring, response schema tracking in relatively soon.
Updating my validation library for python, koda-validate (https://github.com/keithasaurus/koda-validate).
Focusing on ergonomics improvements. Just released an improvement to the __repr__ for Invalid types.
Potentially working on expanding the ability to generate validators from arbitrary typehints, ie `get_typehint_validator(list[str | int])`. It has good coverage, but I suspect I'm blind to some obvious holes. Would love feedback!
Pydantic already covers type-driven validation and it works well enough. What is the main value add in Koda? Just curious.
It's not the core of koda-validate, and yeah lots of libraries have a similar capacity. Feedback I'd be interested in is if there are gaps.
In general the value prop of koda-validate is that it turns validation into typesafe building blocks, which makes validators very re-usable -- and flexible. Some other notable differences from pydantic are that it doesn't `raise` on validation errors, you don't need a typing plugin, and it's fully asyncio-compatible.
- Active recall studying app that allows a user to practice active recall[0]. The app hides user provided content at first and asking the user to try to remember all they can before reading the content. Then the user goes through the material slowly revealing each paragraph from their input. At the end they try to actively remember what they learned and can even compare to what they knew at the start.
- Mixtape sharing platform for midwest emo[1] which is a genre I've really gotten into over the past few years. The community is pretty strong on YouTube for creating "mixtapes" so I wanted a spot that was just for these videos.
- PhotoForge[2] Photographer's companion app which can help me choose photos using a Tinder-esque swiping mechanism. It also has some AI stuff for generating Instagram descriptions. Finally has a watermark tool. Still trying to think of other stuff to add. This was an AI code weekend project so it's like a house on stilts at the moment but I plan to give it some more love soon

In my free time I’m still working on My Financé (I keep getting feedback this name is confusing), which is a fairly undifferentiated personal finance tool.
It’s a labor of love, but I love it!
I’m currently building a simulation engine that lets you forecast your spending, build scenarios (like taking a year off, getting a cat, move to a new city, etc based on your current spending patterns and assets.
https://myfinancereport.com/
It’s great fun to have a project of one’s own to just toil away on.
I don't know what it is about this name, but I read it as "My Fiancé". My brain did not register the first "n" and it wasn't until I read your parenthetical remark that I went back and re-read.
The name isn't confusing, per se ("get married to/be exclusive with your finances", OK), but it also isn't very strong... "financé" is also very strange and awkward to pronounce as a native English speaker. Probably because it comes across more as Spanish-seeming despite it being a play on a French work.
Yeah it was meant to be along the lines of:
My Financé, because you should love your finances.
To your point, I think it’s hard to notice the spelling, and hard to figure out how to pronounce it.
It also is the same spelling as My Finance, which is tricky to rank for on Google.
Overall, it seems like it has potential to be a fun brand, but the constant confusion has led me to strongly consider a “rebrand”.
> I don't know what it is about this name, but I read it as...
same misreading
I'm blaming typoglycemia
Because everybody reads it as a typo of my fiance.
I’m working on https://onebliq.com A lightweight service for Azure cost visibility.
The idea is simple: * See where your Azure spend is going, without learning all the ins and outs of Azure Cost Management. * Get alerts when something unusual happens, with the root cause explained right away.
Still in preview, so I’m mostly looking for feedback from people who deal with Azure day to day. Early access is available if you want to try it!
I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output.
The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output.
https://vedro.io
I would be very happy to receive any feedback!
I like the promise, and it looks nice. But I'm not sure what are the selling points.
- pytest already works with assert. Why brag about something that is already commonplace?
- It could help if your docs explained the alternative to using fixtures. I assume it would be done by re-using givens, but you could make it clearer what is the preferred way to do it, and what is gained, or lost, but doing it that way.
- Can you explain how your diff is better than the pytest diff? (I'm asking as someone who hates the pytest diff)
Thanks for the feedback, it helps me see things from a different perspective.
These are excellent questions, and you're absolutely right that they should be clear from the landing page. I'll work on fixing that.
Short answers:
1. Good point about asserts. When writing the benefits, I was targeting a broader audience (unittest users, people coming from other languages like JS), but the reality is most visitors are probably "pytest escapers" who already know pytest uses assert. I'll reorganize the selling points to focus on what actually differentiates Vedro.
2. The main philosophy is "all you need is functions and their compositions", no special decorators or dependency injection magic. But this is indeed missing from the index page. Will definitely add clear examples showing how to handle common fixture use cases with plain functions.
3. One diff example on the landing page clearly isn't enough. I'll add more comparisons. Since you hate pytest's diff output too, I'd love to hear what specifically bothers you about it, your pain points would be incredibly valuable for improving how I present Vedro's approach.
Because my hate for pytest is ardent and dear to my heart, I will try to explain.
I wrote a very simple function:
When I run it with normal Python, this is the exception: It's compact and simple to understand. It pinpoints the exact location of the error, and I easily scan the text to find the function call-stack.Now here's the pytest error:
It doesn't pinpoint the error, it adds code lines that might be irrelevant, and extra information I don't care about.I will say using `--tb=short` fixes most of it, at least in this example, and sometimes it's even preferable, because it's shorter. But it still doesn't pinpoint the error like normal Python exceptions do.
As someone that loves Python and hates pytest, you have my support.
(Although, I don't like using bare `assert`s in tests, but maybe you'll convince me.)
Thanks for the support! It means a lot, especially from someone who shares the pytest frustration.
About bare `assert`s. Vedro is actually flexible enough to use any matchers you prefer, but let me share why I stick with plain asserts:
1. In most editor themes, `assert` jumps out with distinct syntax highlighting. When scanning tests, I can quickly spot the assertions and understand what's being tested.
2. The expressions feel cleaner to me:
3. I like that there's nothing new to learn, the expressions work exactly like they do in any Python code, with no special test behavior or surprises.Would love to hear what specifically bothers you about bare asserts, always looking to understand different perspectives on testing ergonomics!
Your first and second points makes sense. They don't matter much to me, but I see how others could value those things.
Aside: I also don't like the hamcrest syntax. I also don't love unittest's syntax but it's OK and it's pervasive (i.e., available in the stdlib).
The third point is where I start to disagree more strongly.
> I like that there's nothing new to learn, the expressions work exactly like they do in any Python code, with no special test behavior or surprises.
This doesn't seem true to me.
> the expressions work exactly like they do in any Python code
Not to my mind. In normal Python, an assertion communicates something that is unequivocally believed to be true, not something that may or may not be true (a test). Let me see if I can explain it this way, I often use asserts in tests to show (and enforce) something that I believe to be true and must be true, before the test can have any meaning. E.g.,
assert test_condition() == False invoke_the_code_under_test() self.assertTrue(test_condition())
The "assert" communicates that this is a precondition, the "self.AssertTrue" communicates that this is a test.
I can 100% see that others might not see/care about the distinction, but I think it is important.
> no special test behavior
Well, that's not quite true. You have to handle the AssertionError specially and do some fairly magical work to figure out the details of the expression that failed. The unittest-style assertions just report the values passed into them.
I don't really like that magic, both from an aesthetic standpoint and from a least-complexity-in-my-tooling standpoint. Again, I can understand others making different tradeoffs.
A new type of development environment for working with agents
https://github.com/stravu/crystal
It supports Claude Code and Codex, but has you constantly working on multiple features in Git worktrees. This way you are always able to stay busy while waiting on your agents.
It has built in tools for review, such as a diff viewer, and a quick button to run your application in different worktrees for testing. It has completely transformed the way I work.
Have been working on my blog ( https://bryanhogan.com ) and writing more about using Obsidian well. Last two posts were first how to use Obsidian to make a website ( https://bryanhogan.com/blog/obsidian-website ) and the latest a tour of how my current vault works ( https://bryanhogan.com/blog/obsidian-vault ).
Also working on DailySelfTrack ( https://dailyselftrack.com/ ), an app to track what matters to you in a way that you find relevant. So it is a mix of habit tracker, health log and journal. Like a spreadhsheet app, but with much better UX. And like a habit/health app, but with much greater customization.
I want this to be a tool highly useful for people who have complex health issues, are working towards ambitious goals, or just want to regularly reflect on their day.
I'm building it since I couldn't find a satisfying solution anywhere. It's local first and does not force you into a subscription, or tries to exploit you with any other dark patterns

Right now I’m experimenting with a simple bookmarklet trigger instead of a browser extension. Curious: how do HN folks feel about bookmarklets in 2025, still viable, or do you prefer extensions?
Bookmarklets are nicer, you don't have to install them. AIUI, people hate installing. I hate installing!
Very viable, please go this route!

I want to bring their bikepacking adventures alive in a story format. Cycling trips are often not Monday to Sunday. They might be a few weeks! Everything is geared towards performance. This misses the mark a little bit. I made this app to stitch a trip together. It also has a comparison engine which asks questions like - how many doughnuts? - to translate the trip into things everyone will understand.

My uni is called NUST so I made a better LMS for it called NUTS lms. https://www.nutslms.com. It's a chrome extension that serves as agentic interface for my University's LMS. The AI Agent is called "Deez Nust" and it can do pretty much everything a human can do: - Check deadlines - Download assignments - Even do a quiz for you
I like the mobile version and pricing page.
I'm trying to build a next gen quickbooks competitor.
Something that doesn't nickle and dime you, very cheap (perhaps even open source), has all of the extensibility of a modern ERP, a great UI, and handles complex use cases (revenue rec, expense management, inventory cogs, etc).
I feel like this is solving a real problem, but have no idea how to break into the industry. Just trying to solve my own problems for business accounting but would be nice to know other folks would be interested.
I have been working on my terminal editor, but I parked that for now -- https://github.com/bloomca/love. It is possible to load a file and edit it, copy/paste works, you can select text, etc. The next step is to integrate with the tree-sitter for syntax highlighting and then with LSP, but it took a bit more time than I wanted.
Another project of mine is to play music from my audio CDs by myself. I built a simple Rust library to read TOC and raw PCM data from a CD drive -- https://github.com/Bloomca/rust-cd-da-reader (works on Windows, macOS and Linux), and a ripper -- https://github.com/Bloomca/audio-cd-ripper, which rips all tracks and encodes it as FLAC and fetches metadata from MusicBrainz.
The next step is to play it. I looked into using cpal (https://github.com/RustAudio/cpal), but I feel like using low-level audio API for each platform is a better approach for learning.
A kanji learning app using free dictionary data and the FSRS spaced repetition system for maximum context per card and optimal memory retention.
https://shodoku.app/
https://github.com/runarberg/shodoku
My theory of learning is that you learn the characters better if you learn how to read and write them at the same time. And flash cards are better by giving you as much information as possible about the character.
This is fundamentally different from e.g. WaniKani which only teaches you how to read the character and relies on pre-made mnemonics (plus SRS) for easier retention, and from Anki which (normally) has very minimal flash cards, showing only small bits of information per card. When you have the whole dictionary on each card it gives you the opportunity to create the easiest connection with what you already know. This may be some made up story about the components (radicals) in the kanji (like WaniKani does) a word you already know, other kanji sharing the components, etc. The more connections you make the easier it is to learn them.
One of the features I personally use extensively is the ability to bookmark words containing the kanji, which will then pop up at the top of the words section in a later review. If I remember the meaning and the reading of the words I have bookmarked for this character during a reading review, I consider mark card as good. If I remember none of them I mark it “again”.

Working on Fraim, open-source agents for cloudsec and appsec engineers to complement existing deterministic scanners. Born out of our 3 years of learnings building such scanners for IaC. Turns out in the real world policies are subjective enough to make this hard.
Examples:
- Policies are frequently subjective. Hard to codify, but LLMs can evaluate them more like a security engineer would. "IAM policies should use least privilege." What is "least" enough? "Admin ports shouldn't be exposed to the Internet." What's an admin port?
- Security engineers are stretched thin. LLMs can watch PRs for potentially risky changes that need closer human review. "PR loosens authz/authn." "PR changes network perimeter configuration."
- Traditional check runs (SAST, IaC, etc.) flood PRs with findings. Security doesn't have time to review them all. Devs tends to ignore them. Frequent false positives. LLMs can draw attention to the important ones. "If the findings are unusual for this repo, require the author to acknowledge the risk before merging."

For about two years I am working on dynamically configured, zero-downtime, low-code API and extenaible platform called Hamster Wheel. It is written in C# and today I released first one of few libraries that I developed while working on it:
https://github.com/npodbielski/HamsterWheel.FluentCodeGenera...
It is small helpful library that helps to write Roslyn source code generators using fluent API. Might be a bit niche use, but native Roslyn APIs are a bit complicated to get started writing source code generator. Fluent API helps with that greatly. In example:
- automatically emits using statements
- automatically format generated code
- helps with importing types
- helps with indentation and balancing parenthesis
- helps with adding, using parameters, async methods generation
- provides nicer to use wrappers to Roslyn IncrementalValueProvider
- allows to share pieces of code between files/classes (i.e. interfaces implementation)

Earth Meta Insights
Since a few months back I am working on a side project to give a snapshot of the regional and global species and natural ecosystems.
I use manual (me) and automated tools (web and literature search tools, llms, visualizers ...) to search, extract, organize and visualize ecosystem literature and data.
A regional example of mountain gorilla's of Rwanda: https://www.earthmetainsights.com/emi-cards-gorillas-of-rwan...
A global example of Elephants across the world: https://www.earthmetainsights.com/emi-cards-state-of-elephan...
If there are some species that are you would like to see a snapshot of, and the region/location let me know and i will try to get a similar visualization. DM or as reply to the chat. Share the species name (common or scientific) and location (can be a city, town, region, province, country).
It is a work 8n progress, but I would be very happy to recieve feedback.
I appreciate what you're doing here. I think it's really important to have this kind of high level overview of these species. I have a little feedback based on clicking around the site.
When you click on a country in the map view(under Elephants, for example), I think the map still has focus instead of the card. So this means you can't highlight text, click on links, etc within the card. Also if you scroll using the scroll wheel, you end up zooming in and out on the map.
I wonder if it would be good to have a "see more" link or some such here, so you can view the same information in the card, but on its own discrete page for each country?
Really appreciate that you checked out the website. It is a bit hacky, but for now i am happy with it. Indeed that is correct, the focus is on the map. I am going to fix that. Thank you.
As for the see more, it is in my planning. I can do it manually, but I am waiting for some free time to automated that.

A new way for realtors and potential buyers to do property research.
A "trying to solve my own problem" project. Managing my realestate portfolio and getting an unbiased estimate pricing estimate for new locations i'm interested in is tedious. Doing my own research on a location takes hours.
https://realestate.blackboattech.com/ makes this easier converting all real-estate research into a one click affair. Agent automatically accesses the location and neighborhood to score amenities and gets an average price range for similar homes. Research reports are great for consumers and realtors can have on-demand reports generated for the most up-to-date information. Over time the plan is to have passive tracking of my existing real-estate portfolio notifying me of local events or litigations that may affect my property pricing.

A command-line tool called berk that is a versatile job dispatcher written in c. It is meant to replace big clunky tools like Jenkins, Ansible etc. It has syntax similar to git. It works pretty well, just need to iron out some kinks before final release. https://github.com/jezze/berk
Working on the Restful Atmos Sleep Lamp, a smart bedside lamp that automatically shifts throughout the day and night for the circadian rhythm, reducing blue light at night and maximizing blue light during the day. There is a machine learning layer that learns your preferences and automatically adjusts the intensity of the light, similarly to the Nest Thermostat [0].
Also, shipping Bedtime Bulb v2 next month. This is a hybrid LED-incandescent design meant for the evening that is the best of both worlds: low blue light, high color quality, perfect compatibility with dimmers, 10x less flicker than incandescent, includes near infrared, low energy use, long lifespan [1].

I’m working on designing a system at the intersection of mental health and personal finance.
The idea is simple: stressful or difficult moments happen every day, but they usually disappear with no positive outcome. At the same time, many people struggle to save consistently for the things they actually want (trips, concerts, hobbies) because necessities always come first.
This system links the two: when a user logs a stressful moment, a small preset amount (say $2–$10) automatically gets transferred into a personal “joy fund.” Over time, bad days turn into tangible progress toward something meaningful.
Right now, I’m validating whether people would find this useful before building a product. Curious to hear if this resonates, and what potential challenges you’d see in such an approach.
I’ve been working on https://fontofweb.com, a search engine for real-world web design.
Most design inspiration sites lean heavily on curated mockups (Dribbble) or award-winning showcases (Awwwards, Mobbin). That makes them polished, but they don’t reflect what most production sites actually look like. Font of Web takes a different approach: it sources directly from live websites, and the community can clip specific elements instead of entire pages. That means you can browse navbars, pricing cards, dashboards, etc., not just full screenshots.
Each clip is enriched with metadata (fonts, color palettes, original domain). Search works across that metadata, natural language queries (“minimalist fintech dashboard”), and even visual similarity — so you can find results either by text or by image.
There’s also a Chrome extension to snip and save from any site.
I’d like to hear from designers and frontend engineers: is this useful in your workflow? Anything obviously missing?
Replicated Data exchange format, RDX. A JSON superset that has diff, patches, branches and merges. Once you have that ability at the data format level, many things become surprisingly straightforward. https://github.com/gritzko/go-rdx
I'm building Mighty, a library that lets you render Astro components everywhere.
https://go-mighty.vercel.app/
(Will probably register a proper domain name close to release)
Historically, Astro hasn't had an API like renderToString for React/Vue/etc. that takes a component and renders it on the server. That changed with the release of the Container API last year: https://docs.astro.build/en/reference/container-reference/
But there are still a lot of rough edges:
- Importing components is a hassle (you have to go dig through the Astro manifest or create a TS file that exports all your components)
- No Vite integration (so no local dev support, or hot reload)
- No styling support (this is probably the biggest one)
Mighty will provide dev + styling support and a simple way to import your Astro components, with adapters for Hono and Laravel when first releasing. For Hono, it should be as simple as writing a few lines of code:
https://go-mighty.vercel.app/guides/backend-adapters/hono/#r...
Still WIP, but I hope to have something out by the end of the year! Let me know what you think.
https://go-mighty.vercel.app/
(And yes, I wrote the docs before the code! It helps me structure my API design far better, even if not perfectly)
A little Mac app that syncs markdown tasks to Apple Reminders.

Been working on a simple online radio station player. Very early stages but allows users to search for stations, play them and favourite them.
It's up now but still not "prod ready" but feel free to check it out if you like:
https://www.radiopuppy.com
Nice app. Can you add a share link for a radio and to categorize them by country and category?
A nitpick: I would prefer the spin loader from visible o the centre of the page.
Yes all on the road map. Still in soft launch mode so will fix a few of those things before launching :)
By the way, if you could add the possibility to add missing radios then it would be the cherry on the top of cake ;)
I ask, because one of the main radios in my country is missing from your list, and this is the only major drawback on your app up to now.
biscuit-based identity and authorization
I’m working on https://www.hessra.net/, an identity + authorization service built around [Biscuits](https://www.biscuitsec.org/) instead of JWTs. The goal is to decompose auth primitives so they’re easier to use in service-to-service cases, while also showing off what Biscuit tokens make possible.
JWTs feel like problems waiting to happen. I think biscuits give stronger guarantees and are harder to get wrong.
One piece I’ve shipped is an identity token that can be delegated offline. For example, “company:alice” can delegate to “company:alice:agent,” and that token can then be used to request an authorization token. This makes for a neat API key model: you can issue a simple opaque identity token to your customer (e.g. “customer123”) without having to maintain a DB of hashes/expirations, since those are encoded into the token. Later, you can upgrade security by exchanging the identity token for an authorization token, or let customers delegate access (e.g. “customer123:marketing”).
I’ve also been experimenting with higher-order authorization flows:
• Service chains: each step in a request’s path (edge → app → DB) can add attestations, so later services can validate the full chain.
• Multi-party authorization: requiring two independent services/orgs to co-sign an authorization token, useful for cross-org or on-prem deployments.
Right now I’m building an OAuth 2.1 profile where the identity token replaces a refresh token and the authorization token stands in for the access token. I’m especially interested in hearing where people find OAuth clunky in practice, or stories from folks who’ve built auth systems with other token types (macaroons, biscuits, etc.) or for use cases where OAuth didn’t fit well.
Are Eclipse Biscuits related to Google Macaroons? https://research.google/pubs/macaroons-cookies-with-contextu...
(what a word salad that is...)
Biscuits are in the same family as macaroons in that they are bearer tokens that can be attenuated offline, but they go further. A biscuit carries a chain of signed “blocks” that can contain facts, rules, and checks in a small Datalog-like logic language. That lets the token itself express richer authorization context, not just restrictions.
Key differences from macaroons:
- Crypto model: Macaroons use HMAC, so every verifier needs the shared secret. Biscuits use public/private keypairs so any verifier with the public key can check validity.
- Expressiveness: Macaroons only add caveats (restrictions). Biscuits can encode facts, rules, and checks, enabling more complex policies to travel with the token. so you can attest and attenuate (and do some other tricky stuff if you want)
- Delegation: Both support attenuation, but biscuits do it with signed blocks that are verifiable and can be chained across services.
So conceptually similar, but biscuits aim to be more decentralized and policy-rich.

A tool to track SEC filings and dividend changes via Discord.
I originally built this for myself to track my investments, and decided to turn it into a product. I’m planning to add more functionality to support investment research.
I'm toying around with a language that's like Python but with Hindley-Miller interference and some functional stuff. It's not a superset or anything, because I can't do that, but it's interesting how well HM (plus some well-encapsulated escape hatches) map onto the Python ecosystem with all its dynamism.
Very interesting idea. Good luck!
A burnout detector for SREs. The goal is to help teams identify incident responders who may be overworked/getting burned out.
We are looking at:
-Objective data: signals from incident management tools (Rootly/PagerDuty), GitHub, and Slack
-Self-reported data: asking the engineers how they feel via short survey
From this, we generate a CBI score (Copenhagen Burnout Inventory). We're still in beta, but we've received positive feedback from our beta testers, especially from manager of large and distributed orgs.
It's fully open-source, you can test it out locally https://github.com/Rootly-AI-Labs/rootly-burnout-detector-we...
Alternatively, we offer a hosted version with mock data, allowing you to play with it. https://www.oncallburnout.com/
If you have any feedback or ideas, shoot them my way :)
Very good idea. I could have used this multiple times in my career. I am a go until I drop type of person, and I'd just keep going.

Emilia, a personal relationship manager. Every once in a while I meet extended family (wives of cousins or their children) or I meet a fellow soccer parent and I forget their names, or who's related to who.
I've used Monica HQ to keep track of this but thought I could tackle differently using AI. With AI you could ask questions like "who's everybody on my aunt's side? Like cousins and their family" and get a good answer.
Afaik other "relationship managers" out there are professionally oriented, for sales people. A lot of them talk about LinkedIn integration, for example.
Take a look at http://emilia-workers-website.inerte.workers.dev/ and if you're interested in Alpha testing, send me an email at inerte@gmail.com - I setup a Discord last week so early adopters can chat with me about.
For the last year and a half, maybe 2 years, i've been working on a 2-man project with my brother. We're trying to make an AI marketing tool that hopefully isn't complete slop: https://www.img-pt.com/
About 2 years ago we were trying to get a marketing agency off the ground. For context, Dall-E 3 was brand new and the AI hype was just starting. We thought, why not try making ads with it? It obviously went terrible. Those old models are junk now, but the idea was there, and we just kept at it.
A big part of the journey has just been getting constantly outrunned by new tech. Just when we'd get close to a decent workflow, a better LLM or image gen model would pop up and we'd be playing catch-up.
We've managed to somewhat keep up and are now focused on image ad gen. what we're working on now is video ads. Not the usual UGC-style stuff other startups are doing, but a more cinematic, polished style of ad. i've seen these made manually on IG, but haven't seen anyone automating it. We'll probably try to ship this in a week or two.
We're also working on a campaign management thing that can take a meta ads campaign, spit it into ad sets for the funnel, and create the right ads for each. it'll also be able to shift budget to the ads that work and swap out the ones that don't, all automatically in your meta account. that'll probably be rolled out in 3 weeks, fingers crossed.
We'd be glad if you could test it out and give us some feedback. i'm mainly interested in whether the ads are actually usable in a real-life campaign. A lot of the ad-gen tools i've seen feel like a nice proof of concept, but they're a bit sloppy and not something you'd actually use. i'd be very glad to know if you find it practical.
You can find it here: https://www.img-pt.com/
I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts, GitOps style and I think it's really starting to hit its stride. I just released a new version yesterday: https://github.com/stryan/materia/releases/tag/v0.3.0 .
There's been a couple attempts in this space before but they usually seem to peter out after a while. I'm hoping to avoid that by staying flexible and focusing on just managing files instead of creating a new compose-like DSL. But even if it doesn't become popular I'm just happy I don't have to manage my homelab with Ansible anymore :) .

This is really cool! Does it take care of the 'deletion' of everything it creates if you remove config blocks/files etc.?
Yep! Everything is designed to be atomic/deterministic so you don't need to worry about materia itself causing any state drift.
I have a friend who is having twins. I'm using some new woodworking techniques to make a pair of baby rattles for her. The real challenge is trying to make two shapes with organic curves and precise cuts that are as close to identical or mirror-image as possible, while also hiding the joints.
It's very low-tech. No screens, no CNC, the most technically advanced tool is the digital RPM readout on the lathe. It's nice to disconnect from my screens once in a while.

We're building Doctly.ai - PDF Extraction with AI.
We started out with document conversions to Markdown but quickly realized that most use cases were for JSON conversion. We recently launched our "Extractor Studio" where you can have AI analyze a few sample variations of your documents and come up with a schema for you and publish it to an API endpoint.
We've built a technique on top of AI models that dramatically improves run to run consistency of JSON output.

I'm quietly adding "pull requests" for data to Grist https://github.com/gristlabs/grist-core/issues/1829 - been wanting to do this for a long time.
I tried doing this years ago as a stand-alone project and it was too much. I wrote a data diff/patch/merge tool called "daff" that worked okay. But I've always wanted to add this to a proper spreadsheet tool like Grist.
I really want people working on data projects to be able to work more like coders, with pull requests and reviews. Not all data projects are as curated as that, sometimes your data is just a big soup, but when it is curated, there should be a better workflow.

I’ve been working on an app called Lång. A daily spending guide. It shows you what’s okay to spend based on how much needs to last how long.
For over a decade, I’ve thought about how most people seem to resist the advice about money. And also how all advice is based on the same idea: seeing where your money went and making monthly plans based on that.
I think people feel that this is a poor match for how money works. So they improvise. And because we tend to not discuss money with others, they improvise on their own. What this typically looks like is checking their balance and trying to pace things.
I’ve been trying to design the app around that. Providing support to what seems like a natural, instinctive approach to managing money.

I've been wanting to build something like this for myself, but partnering/integrating with banks seems to be the main difficulty. How do you solve this?
And which cards / banks does it support?
Also, what does the name mean? It might be a tad difficult to google, unfortunately, since I imagine that googling "lang" would come up with a lot of other results.
It doesn’t integrate with banks. You log as you spend. It’s a common question, but I think there are many reasons to keep it manual. It keeps you aware of what you have left. And automation won’t ever be perfect, so you must keep an eye on it and adjust things.
The app focuses just on your everyday spending. You don’t log bills and subscriptions. And it’s not about being exact. You can add the rough total of what you spent. It acknowledges that when you plan your spending, it’s really just a guess. And you’ll adjust the plan as you go.
What did you have in mind when you thought about building something like this?
The name means ’long’, and is pronounced similarly. Naming is of course hard. I’m hoping that it will be something you remember.
Linear-inspired wiki:
https://outcrop.app
I've been working on Outcrop full-time for a few months now, since I left my job at Stripe. I think knowledge base systems are some of the most important components for successful companies. Current tools are too slow and too messy. Many companies end up developing a custom internal wiki to supplement their Confluence one.
Outcrop is powered by custom search, collaboration, and authorisation engines. Everything is indexed, including comments. Search and navigation are instant. I have a long list of itches I want to scratch with this product. I'm doing a round of private previews to collect feedback, if you're interested, please sign up, I'd love to talk you!
I am working on a tool for testing web apps with a simple to use syntax/DSL aimed to reduce work for automated testing of applications, based on Playwright (Go).
It has additional cool feature like documentation generation in which the steps of the UI test can be used to generate a markdown document with screenshots to aid teams in crafting end-user documentation.
I am planning on adding reports like Playwright and Cypress support and then later on adding support for running tests on remote browser instances to enable different workflows

I'm writing a minimal, educational WireGuard implementation to practice networking and cryptography: https://github.com/drio/miniwg. It's still in heavy development, but it's been a great learning experience. I've already been able to create tunnels between two miniwg instances and between miniwg and Jason's WireGuard from the Linux kernel.
Before that I wrote: https://github.com/drio/unboxing, a c/webassembly implementation of Danielle Navarro's beautiful IFS fractals.
I’m building Ganttify for a while now https://gantt-chart.com
The goals is to become THE Gantt chart add-on for anything. Currently works with Todoist, Basecamp and Trello. I’m struggling to find more markets.
It’s basically “Turn X into an editable timeline with syncing capabilities and dependencies”
Open to suggestions and ideas how I can make this take off.
I’m currently in the process of consolidating every integration into a single account. Previously (currently) it was “Ganttify for Trello” or “Ganttify for Basecamp”. It will become “Ganttify, connect one or more integrations to your liking”.
That might help simplify things for users I suppose.
I’m solo-coding the clear commercial project smmdealfinder.com which is not ground-breaking or amazing as these other great projects here, but its been an amazing journey for me personally for the last 18 months and has developed me probably from a junior engineer to senior+/staff.
Whilst I’m recently really critical of most AI posts here, this wouldn’t have been possible without AI, but mainly because AI could feed my curiosity and barely any riddle was unsolvable, when I put it into pieces and combined it with debugging (and checking docs). Actually most riddles on my level weren’t unsolvable before, but AI reduced the friction and speed of learning for me. This actually goes beyond coding. In life I just ask and learn a lot about, washing, cooking and domain-specific terms.
I'm building a mindfulness app to help people set daily intentions and practice gratitude — https://www.justfortoday.app/
It’s a free app called Just for Today, inspired by a poem I found in the book How to Stop Worrying and Start Living (amazing book). - It’s completely free; - No ads; - No account; - All offline - Everything stays on your device;
The poem is a gentle reminder: - You don’t need to fix everything today; - You just need to be present — Just for Today;
That simple idea became the heart of the app.
Each morning, the app invites you to: - Set a kind intention; - Check in with how you’re feeling; - Practice gratitude; - Write a little — just for you;
If you try it, I’d love to hear what you think.
I'm trying to get my agentic software specification tool Arbiter to release (UI polish/debugging is so slow :/, browser shenanigans are harder than Rust fr). It's basically a tool that AI agents can use to construct a project specification. The twist to Arbiter is that the specs are structured and validated, and you can compile them to get:
Services with stubbed endpoints, UIs with placeholder components, Dockerfiles/Terraform/K8s infra, E2E tests (via declared flows), Github/Gitlab epics/issues/subissues
It's also got github/gitlab webhook integration, so you can do stuff like trigger agents reactively when events occur on a repo, it includes cloudflare tunnel support so you can set up webhooks even in a local dev environment, and the project generator is fully customizable.
How does it work? is just a documentation specification like spec kit?
Nope, it's a structured spec agents construct using a CLI or MCP (you can also interact with the spec using a web UI). It's CUE, and validated against a schema. Instead of taking your conversation and generating a markdown document that agents might (but often don't) respect, the agent populates the spec in the service from your conversation, then when you're done you can use the CLI to automatically generate a bunch of code.
I read a paper called "The Rise of Subagents" by Phil Schmid at https://www.philschmid.de/the-rise-of-subagents and thought it was an incredibly powerful architectural pattern for running AI agents with complex tasks.
So, I decided to build a practical implementation of this system with a central Orchestrator that manages a fleet of implicit or explicit Subagents. Each subagent is a specialized, isolated AI agent designed to perform a specific subtask. More details in the repo README at https://github.com/skanga/conductor
I have a steep pitch (1:1) roof, and I'm building ladders so I can get on top of it for cleaning, etc. I actually did this a decade ago out of wood, but it apparently hadn't been inspected / seasoned / treated correctly (by the people who produced the lumber) and after a couple of years the thing started growing mushrooms so I had to tear it all out. Just re-roofed a month ago. Building it this time out of mild steel. Cutting, drilling, bending, welding... oh my! Plus there's the risky business of assembling it in place on aforesaid slope.
If I don't have a consulting gig where risk is taken seriously, I can always work on my house or my motorcycles. :-p
I'm working on ScaleDown [1], a context pruning API.
So over the past few years, I have seen how contexts have been steadily growing in AI apps. And while the context lengths of LLMs have also been increasing, they are still effectively about 200k tokens. The performance drops off a cliff after that (you might have noticed it as well with long AI chats).
It is a simple API that prunes away irrelevant parts of a context for a given prompt, a.k.a. context-aware pruning. Integration is super simple: just an extra API call before the final LLM API call. You can get an API from the website.
I would love to chat if this is something that is relevant to you and if you have any feedback on what we are building!

I built a fairly sophisticated Discord bot called Musebot that integrates with both Ollama and ComfyUI: https://xcjs.com/discord
I'm working on a WordPress PaaS with dedicated lanes for bots. The status quo around WordPress is that you block bots using Cloudflare, else your site crashes. Since AI search is here to stay, we need a way to let bots crawl WordPress sites without crashing the server.
Currently at MVP stage, no domain yet.
Regular Cloudflare + heavy caching should solve all crawling problems, no?
For most bot visits, there should not be a single database request.
I am working on a answer engine for Hindu Scriptures and old Sanskrit works. I already have a corpus of all the documents which are indexed and currently working on a LLM based answer engine that focuses on answering questions from Vedas and Upanishads and Mahabharata (for ex). Think perplexity but completely focused on Sanskrit sources with proper quotations from the exact verses where the answers are found.
Planning to release this into the wild for people to use. I currently am struggling on how to fund this properly as the server costs are going to be huge for such an effort (search engine + LLM).
I've been working on 'Fragno', a TypeScript framework to build full-stack libraries with. It allows the library author to define backend routes, and provides them with reactive primitives for building frontend logic using these routes. This all embeds into the user's application. Eventually, it should include a data layer as well.
The ideas are in large part inspired by Better-Auth, which is built on top of similar primitives. I hope more libraries will be built in this manner, because I believe that it provides very nice DX for the integrator/end-user.
It's not quite ready yet, but I did write most of the documentation.

I'm working on a video platform called Nickel. 5-second clips and 5-minute (max) videos. I've been slacking on development but realized recently that I lack focus and am easily distracted by other projects. I wrote about this yesterday.
https://blog.webb.page/2025-09-28-ikigai.txt
I did figure out something I've long wondered about recently. Y'know how you can see previews of videos in Messages? I got it working! Here's an example video: https://nickel.video/6NI3n_IlIlII
My inspiration for Nickel was 1) missing Vine and 2) not wanting to use YouTube to share my gaming clips.
I'm working on https://X11.Social, a voice-first content creation tool for X.
The initial idea was "call to tweet", the ability to compose posts on the go by having a natural conversation with an AI assistant over a simple phone call. This is useful for turning thoughts from a walk or drive into a polished "brain dump" post, or for engaging with user lists without being at a computer.
It has since evolved into a broader system:
Chrome Extension: A context-aware assistant that lives in the browser. It has a Quake-style console (activated by opt+space) for quick chat and can analyze the content of any page you're on (e.g., YouTube transcripts, articles, other tweets) to help you create relevant content.
Engagement Predictor: A feature that scores tweet drafts in real-time to predict their potential for engagement. It's built on a model trained on my own dataset pulled from the X API and other public dataset from Kaggle[0].
Scheduled AI Calls: The system can call you on a predefined schedule to proactively brainstorm content ideas.
Here is the tech stack:
- Frontend: React, Tailwind, shadcn/ui
- Auth: X OAuth
- Payments: Stripe Subscriptions
- Voice AI: ElevenLabs Conversational AI, Twilio
- Engagement Predictor ML: Python, scikit-learn, XGBoost on a data pipeline from X API v2 and a base dataset from Kaggle.
- Chrome Extension: Same as Frontend and Chrome Extensions API
- Blog: Jekyll
- Infrastructure: Deployed on AWS Fargate using AWS Copilot for orchestration (ECS).
I'm building solo and just got the first trial user after 87 days of building in public. It's a long road but the feedback so far is encouraging.

I’m working on a new vision-language model architecture called Onida. Our aim is to match—or surpass—the performance of leading VLMs like LLavA and CogVLM, while operating at a fraction of the cost. Unlike most existing VLMs, which layer vision components onto a language model as an afterthought, Onida is designed from first principles with a truly integrated approach.
This document [1] outlines our key differentiators, and we’re now inviting beta participants to explore and test the technology.

A side project that takes legal documents and uses TTS models to create a narrated read out of the whole document.
Part of the reason I'm building my own solution is that legal documents are often distributed in PDFs which can have all kinds of formatting issues when converted to plain text. There's also specific jargon and formatting that may or may not need to be included, or spoken, or even spoken differently, that I am finding no commercial TTS platform like ElevenLabs really accounts for well. It's all about the pre-processing and chunking.
Also, the commercial models are expensive when you're routinely throwing dozens of pages of text at it.
I've been working on three micro-saas, all built in Elixir/Phoenix:

Can I install this as qemu/virtualbox/kvm/etc VM or does it only work on bare metal?
I'm working on a notes app that is as simple as Apple notes, but has native markdown support and uses semantic search.
Uses SwiftUI for the UI, and Zig does most of the heavy lifting on the backend. It's inspired by ghostty which uses a similar setup[1].
Right now it only works for Mac, but I'll be porting to iOS as soon as I get the markdown renderer polished. It's not available to the public yet, but I'm using it as my daily driver and hope to release it later this year. I've open sourced it so you can see the source code here[2].

https://Drop.Top - A lightweight emoji-based feedback widget in minutes, so real users can drop contextual bugs, suggestions & ratings — all tied to session replays. See trends, sentiment & hotspots in real time, then feed feedback straight into your Jira/Slack/analytics stack.
Building an app to help me stay in touch with my friends (https://wavepal.app).
I have ADHD and often forget to reach out to important people in my life, not because I don’t care but because “out of sight, out of mind” is EXTREMELY true for my brain.
I started building Wavepal with a friend earlier this year so I can track when I last chatted with people, what we talked about, important details that I’m likely to forget (kids names, important dates), and it auto sends me reminders when enough time has passed since we last talked.
I'm working on exploring an exploit in physical security systems that I haven't seen anyone investigate before (at least, not published on the internet). It's involved an interesting combination of reverse engineering, pentesting and regular prototyping/hardware development.
Currently writing a run-through of it to publish on my website. I'm not sure how secretive to be - I think I just want to be the first to actually release my findings. In my post I'll detail the steps to reproduce my results so more people can look into this.
So far I haven't found any critical ways to (ab)use this access control system weakness, as it only typically applies to the outer layer of physical security.
What's your website?
I am working on the MVP for https://www.thelabcompany.co/ the professional network for Upskilling. Solo founder. Experimented with asking LLM for a skill graph of AI skills from git. That went nowhere. Now looking to do something simpler - RAG + memory of user feedback to guide the user on fun projects to build that also include cutting edge skills.
Would anyone want to build skills just for the joy of building? Is everyone who signed up wanting only a job? will leave the network as soon as they land a job? what would you do?
I'm working on a site for filmmakers to help showcase themselves!
Why? >
LinkedIn isn't for creatives. Actor's Access is dated and charges a ton for basic extras Squarespace/wix is fine but everyone in 'the biz' has one and nobody wants to maintain it. Plus they're all silo'd.
Check out my site if you wanna. You get to host your own headshots, resume, and reels. You can upload your screenplay there and hear it read outloud. You can put up your cinematic scores and make a place to send people to hear your music.

Looking for users who wanna test the system out. Give me a shout and I'll throw you some credits if you wanna hear your screenplay read outloud.
Working on a session recording app: https://scryspell.com
Currently it's meant to help devs fix UI and UX issues by seeing exactly what their users saw, including a log of the browser console and network traffic.
I say currently because it has preset analytics (charts for top entry page, top exit page, etc) but am working on letting users define their own trend and funnel charts. That will open it up to basic web/product analytics.
The goal is to be simple analytics + session recording w/ masking.
TechStack:
UI: React, ReactQuery, TypeScript
Backend: Java, SpringBoot, jOOQ, PostgreSQL
Using rrweb for the session recording.

An editor for creating custom accessible color palettes for web/UI design. :)
https://www.inclusivecolors.com/
It gives you precise control over every shade/tint (no AI or auto generation!) so you can incorporate your own brand colors, and helps you build palettes that have simple to follow color contrast guarantees by design e.g. all grade 600 colors have 4.5:1 WCAG contrast (for body text) against all grade 50 colors, such as red-600 vs gray-50, or green-600 vs gray-50. There's export options for plain CSS, Tailwind, Figma, and Adobe.
I'm really open to feedback on what problems and needs people have for creating accessible designs!

A (so far) simple AI assistant to provide help if you're moving with your pets to a different country. I've got a vector db with some US travel documents embedded, parse the question/prompt, and add the relevant context to a standard LLM request.
It also parses the question/prompt and stores move and pet details, so later questions will have context.
Eventually, the idea is to have a full tracker and reminder system... so deadlines, appointments, and documentation can be stored and referenced in a single place.
I’m working on Colanode, which is built to close the gap between the convenience of cloud tools and the ownership of local software. It brings chat, docs, databases, and files into one open-source, self-hostable workspace where data lives on your devices first and syncs in the background. Unlike typical SaaS tools, Colanode is local-first: everything works instantly and offline, infrastructure stays minimal, and you keep full control of your data.

Hobby. Very rudimentary, not everything working yet.
Think ansible for your user account (except it will definitely not be ansible for your user account).
Whenever I have a new machine, I do the same steps over and over again:
- Installing some packages (like make)
- Setting up an ssh key
- Cloning some git repositories
- Setting up dotfiles
- Installing rustup / rust
- …
Until recently I tried doing all of that with a bunch of bash-scripts, but that turned out to be messy and not a joy to maintain. So now tried a slightly different angle with a rust tool that you can just pull out of the CI, no dependencies, and it will setup everything (for me).
I am building an Options: At-the-Money Premiums tracker to help me view all the options premiums on one screen. Here is the app: https://apps.apple.com/us/app/options-at-the-money-premiums/...
Launched on Reddit last week: https://www.reddit.com/r/Optionswheel/comments/1nlelbp/comme...
If you guys trade options (selling CSP and CC), I would love to hear your feedback.
Where do you get the data?
https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a proper accounting foundation.
It's a double-entry personal finance tool where you own your data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Soon with multi-currency support. Currently targeted for desktops.
It's interesting in many way. Using double-entry (it's a perspective shift and a power tool), the challenges and advantages of building local-first app, UI/UX & visualizations, privacy and more. For personal apps, local-first is a good fit.
I still am not sure exactly how to define it, but it's a ruby library, that is mix of a rules engine+spreadsheet feelings+array language+static validation+compiled/codegen... that last part is mostly not merged yet but yeah, ruby DSL codegenerating ruby, it's ruby all the way.
https://github.com/amuta/kumi/tree/codegen-v5 (see ./golden for more context on the compilation/codegen. I barely knew what a compiler was before doing this so I might have just created some nonsense )
I'm building with python/fastapi, react/tailwind/vite, with Claude Code and using test-driven development.
Red-green-refactor is tedious for humans but perfect for AI. And the test names & code make great documentation of every micro decision, running in milliseconds to prevent regressions.
The software itself helps people perform construction approvals.
Old way: dozens of documents and versions sent back and forth over email. Many fiddly details that must be checked - to streamline the process we'll use AI to provide verdicts that help humans make decisions.
I plan to create content & teach what I've learned.

I am all-in on a Unity game right now. Working with one other person and hoping to ship to Steam later this year.
Thinking about play testing at scale is a new thing for me. I've been getting into visualization techniques like using 3d textures to build voxel heat maps in-editor. We've managed to accumulate quite a bit of play testing telemetry already. The power of aggregated statistics in the editor views is absolutely mind-blowing to me. For level designers it's like having proper omniscience. Being able to see things like thousands of samples (manifesting as a bright red voxel) that wound up tripping over the same misplaced geometry is like cheating.
I'm working to build a tool for macOS and Windows desktops to help non-technical users figure out what's wrong with their home internet and how to fix it. https://www.networkweather.com/
It's literally just me in the garage right now banging out prototypes, talking to MSPs, and probing networks/WiFi/OS to make this tool.
The hope is that companies care whether employees are productive when remote/hybrid/on-the-road, or at least are sick of trying to triage first line helpdesk tickets about home network issues and Zoom glitches.
I am currently building a lot of AI models for predicting both individual athlete and team based performance for https://www.higherscoresdfs.com/dfs/spa/welcome/
Like the rest of online mass media, HN covers generative AI a lot but there is still plenty of value in predictive AI. Both forms provide plenty of technical challenges to the AI engineer. I miss the days when you could get a stack trace to when debugging an issue.
Since no one seems to be doing any Erlang, here goes --> I've been working Erlang-Red[1] which is Node-RED flow editor with an Erlang backend.

Trying to document my current hobby project, but stuck in the analysis phase. I dont even know what it is. When I try to describe its purpose I get blank looks. People tend to need physical demonstrations to understand whats going on. Its not entirely new, or novel, its definitely not revolutionary, but it is a hybrid of so many things, in a very indirect sense, that its just beyond my verbiage. Not a humble brag, I dont think its amazing or anything. I have just failed to describe it. Have been trying to get a phd I know to look at it, and describe it for me, but he just straight up isnt interested.
Maybe video yourself using it / it functioning / building it / playing with it or whatever...
Er... is it software? Hardware?
Has both. Hardware is mostly in the prototype phase.
I worked on Dockside last year (https://hachipoo.com/dockside-app) — a small macOS app that makes use of the unused space around the Dock (especially nice on widescreens). It’s non-intrusive and lets you drag & drop files, jot quick notes, or add shortcuts right beside the Dock so they’re always handy without cluttering the desktop.
Right now I’m adding few of the most requested user-requested features (vertical Dock support etc.) and working on refining it for Tahoe release.
Banker (banker.so): An AI spreadsheet that excels at spreadsheet understanding (pun intended).
There are some AI spreadsheet products out there mostly as plugins along with MS Copilot. However my experience with them showed that they are bad at understanding spreadsheets.
The reason is that sheets are 2D data models. Because LLMs are trained on 1D data models (simply text), translation of 2D data models to formats an LLM can consume is a big context engineering task.
I read and implemented some of the algos mentioned in SpreadsheetLLM paper released by Microsoft. Ironic, isn't it?
Got it to a nice working state. Give it a go - if you need more tokens, let me know!

MAXSTACK: Web framework for rapidly building SaaS apps with AI - trying to enable the next wave of 'fast-fashion saas'. Think of it like better-auth is doing for auth, I want to do for the rest of SaaS
- comes with common SaaS features pre-built (crud, blog, auth, etc.) - import templates from the framework until you want to customize them - create forms with just a zod schema - good docs, typescript interfaces, a CLI for common tasks, and MCP for your AI agent
If you're building something now or want to - I'd love to help. Could use the experience to make things easier through my framework.

I’m still working on Simple Observability:
https://simpleobservability.com
I built it because I needed two things:
- A super easy-to-install monitoring tool that doesn’t require bash scripts or config files
- A mobile-friendly, UX-first interface where I can check everything from my phone
It’s now pretty feature complete. I can see a full picture of all the servers and VPS I run straight from my phone.
Setup is one command, no config files, and everything else happens in the UI. There’s a catalog of predefined alert rules, and creating new ones is easier than anything else I’ve used.
There’s a free tier if anyone wants to try it!
Very cool! However I couldn't get the agent running on an ARM based Oracle Linux Server 10 in OCI. I tried two different servers
level=ERROR msg="failed to fetch collection config. retrying in 5s..." error="GET /configs/ failed with status: 204"
That’s not actually a bug (maybe the message need to be more verbose). The agent is running, but it doesn’t yet know what data to collect. You’ll need to finish the setup in the UI by choosing what metrics/logs you want. Once you do that, the error will go away and the agent will start collecting data
Ah thats what I get for not readin! It's working perfectly! The only thing missing for me is ingesting the logs for my service directly from journalctl, that would be amazing

vulnerability discovery and exploitation, with zero false positives.
https://vyprsec.ai/
Yep, you read it right. 0 false positives. We scan the whole codebase for possible vulnerabilities, rank them, write the proof-of-concept for exploitation, spin up the software in a sandbox, and then attack. All of them happen autonomously without human involvement.
The end report? Only verified vulnerabilities are being reported without noise.
Already reported some unknown vulnerabilities in open source projects. The good thing is we're just getting started.

I'm working on a product to break down information siloes for private market investors. A lot of data for private equity, private credit, and venture capital firms lives in memos, deal books, conversation notes, emails, and chats. In some cases, attempts to organize that data in a more structured format (e.g. using the CRM) has resulted in data not getting recorded because of the friction of managing those types of systems.
So basically, I'm building a system where users can query all of that unstructured data and add more with a little less friction.

Shared memory for AI coding agents. Every agent currently reinvents the wheel - your agent debugs a Stripe webhook signature issue that mine solved yesterday, burns tokens doing it.
Building the retrieval and memory maintenance layer. Interesting problems around decomposing solutions into reusable patterns, ranking/deduping at scale, keeping latency under 100ms. Uses MCP so it works across IDEs.
Early benchmarks look promising. https://memco.ai if you want to try it.
I'm working on a tool to do evals for voice agents. The way it works is that you simply post your recordings, tools, instructions, etc and we do a diff to spot if something changes, then we mark a note on the change and run evals.
The main idea is that you don't need to configure anything, simply send us the data and we should figure out evals for you.
If anyone is building with realtime voice send me an email at username at Gmail and I'll try to help you improve your tool for free (In exchange I get to talk to real users)
Building https://multi.dev, an AI coding agent with bunch of FOSS contributors
We took a great amount of learning from tools like Cline, Roo.. After spending some time on their tech as active users/devs, we decided to build multi from scratch with drastically different take on core features, tech stack, ux/devex..
If you are an active user of similar tools, and/or want to try multi.. We want to hear from you.
-- edit: I am one of the core contributors to multi. And we are in the process of open sourcing it.
I’ve been using tools like Cline and Roo-Code quite a bit, and the idea of rethinking the core stack/UX from scratch resonates a lot. The agent workflow and devex feel like the hardest problems to get right, so I’m curious how Multi approaches context management and long-running tasks compared to the others. Excited to see it open-sourced and will definitely give it a spin.
> I’ve been using tools like Cline and Roo-Code quite a bit, and the idea of rethinking the core stack/UX from scratch resonates a lot.
Would love to learn more about your experience with cline. We spent quite some trying to add multi agent capabilities and improve the overall ux/devex of Cline (and its clone Roo) to make it more intutive for developers. we found that its stack is not built for these capabilities, and the codebase was not as stable as we would like it to be. it required a major rewrite, at that point being another cline clone made no sense to us.
> The agent workflow and devex feel like the hardest problems to get right
yes, AI coding agents are probably the most complex agents out there. our approach comes from actor model, where each agent manages its own event-loop. we found this is incredible robust way to build specialized agents that interact with one another within multi. Too early to say but
> Excited to see it open-sourced and will definitely give it a spin.
thanks. still brewing but will let you know. appreciate your feedback.
Love to try this out! We're using Cline already
thanks. would love your feedback once we launch.
What's the difference? Tell me more.
we redesigned the whole system from ground up for robustness, speed, scale and multi agent capabilities.
I created a 2D platformer inspired by the classic Mario games. The game is called Jolly Land Adventure and I made it because I wanted a simple platformer that's easy to just pick up and play.

Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them.
Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods.

pptx-tools, a collection of cli tools for interacting with Powerpoint presentations. Covers use cases that PowerPoint doesn't support. Currently in the making:

* pptx-dump - dumps extended info about a powerpoint, such as number of slides, applied master slides, used fonts etc.
* pptx-lint - allows to define validation rules for pptx based on content and/or formatting. E.g. presentation must not contain word "TBD", all text must be formatted in Arial etc.
I joined two current interests, my need to learn better JavaScript (since I never used it much) and the discovery of programs like PICO-8. I realize TIC-80 is basically the same but allows me to use other languages, so I’m trying to write small games using JS. I’m still on the struggle phase, trying to learn how to make sound effects, music etc. but I like the fact it comes with everything you need to create whatever you want. Also like how it makes you forget about all the giant software complexity nowadays.

ViewMD - A Mac Markdown Viewer app
It looks like Markdown is having a bit of a heyday with it being the default mode of docs for AI coders. And it became apparent that there is no simple, but powerful Markdown viewer for the Mac, so I made one.
It supports all the usual Markdown formatting but also diagrams and equations so you can get Claude to not only write up your system docs but also supply a diagram of the database structure, logic, or AWS services.
It would be cool if you gave it a go :-) It is in the Mac app store "ViewMD"
After I made a small MMO prototype over at https://everwilds.io/ (open-source) I am now working on a vehicle building prototype at https://evergate.io/, if you're interested in following the progress there's a Discord link at the top right corner of each website. Mainly focused on Evergate right now :))
I've been vibe coding this and that all summer. I'm making a team retro clone for sprint retrospectives, a typeform like form builder and hosting, a Reddit client with AI analysis of trends and a few other things like in various stages of development.

I’m building https://analytics.robomiri.com, a lightweight, privacy-first analytics tool that gives you real insight without turning your users into tracked profiles. It captures page views, content engagement, funnels, and user paths in a minimal UI. My goal is to balance usefulness with simplicity: metrics you can act on, not just dashboards to stare at. I’m leaning hard on defaults like anonymization, flexible retention, and user control over what’s collected.
The hardest parts are always the ones you don’t see: scaling storage & query times, making interpretation meaningful (like “this bounce rate is unusually high”), and doing all of this in a way that’s GDPR/CCPA friendly.
Why do this? Because I believe analytics doesn’t need to feel creepy. You should be able to learn about your users respectfully — see what’s working, diagnose what’s broken — without handing over control or trust.
I am working on https://productpageshots.com

Then it uses Google Gemini Flash 2.5 to generate the actual recommended shots.
You can download them and insert them in your product listing.

Looks cool. I would be honored if you added my blog. Each post is a summary of a recent computer science research paper.

Trying to build a secure, configurable and easy to use authentication system (relative to my understanding)
I have experienced knowledge gaps and blind spots that I am attempting to fix. For example most users worry about security of hashed passwords and yet they do not realize that the TOTP (eg Google Authenticator) use symmetric encryption and quite a lot of the authentication providers store the private key in plain text in their database. List goes on...
Thinking about vibe coding a Behaviour Change App as opposed to a simple habit tracking app. I have personally used the habit tracking apps, and they are absolutely useless. My app will help the users learn how to actually change their behaviour, teaching them micro skills like value alignment, self-compassion, etc. These micro skills will help them in all aspects of their life and mainly to change bad habits.
TrailerSpoiler.com [0]
It annoys me how much a bad trailer can spoil the movie, so I made this platform to rate trailers how "spoily" they are and how good they are. To my surprise, you find some great trailers without many spoilers, but then you will have trailers which are basically a 3-min summary of the movie.

Under ideal conditions (emacs bootstrap running in a loop with FUGC_VERIFY=1) it reproduces about once a day.
Under non ideal conditions it reproduces once a month.
Seems to have something to do with large objects maybe? Anyway, wish me luck. These low-probability concurrent GC bugs are the worst
Built an app that lets you search inside Youtube videos and jump to the specific moments where something was mentioned.
For example "Paul Graham interview best founders" will surface moments where pg talks about founder qualities: https://www.youtube.com/watch?v=BXqk9QaV-ag

I'm building Kavla, its an infinite multiplayer canvas for data analytics.
I have a video on how it works on https://kavla.dev/
And a live demo here: https://demo.kavla.dev/
I've been working in the data space for five years now. Kavla is something that I personally feel would make my job more fun!
Built with tldraw and duckdb
Very cool. Also very performant on the UI. On a side note, I can see this becoming very popular among a Greek audience due to its name.
This is cool - I like the concept and the usefulness.
Thank you! It means a lot!
I'm working on a new type of git forge[1], optimized for speed and work with patches.
It goes to extreme lengths to ensure great performance, i.e. rewritten most server-side parts of git from scratch, so there is no "exec"-ing git nor calls to libraries like libgit2. The frontend should also be very fast thanks for HTMX.

I'm working on Zettelgarden: https://zettelgarden.com.
It's a personal knowledge system. It's a zettelkasten with an LLM substrate. It uses LLMs to build a model of the theses, arguments and facts used in cards, and uses these to both summarize the information on the card and to automatically link cards together based on shared concepts.
I'm working on a project for people who are new to web development and open source. It's called code contributions
https://github.com/Roshanjossey/code-contributions.
Users will go through a tutorial, add an HTML file and submit a pull request to the same repository on GitHub.
Early stage with ARK Cloud API & Stateful LLM sessions without input token costs. Conversation history is kept server-side, so you only send new messages. Demo and docs: https://ark-labs.cloud/documentation
Looking for feedback on use cases and session controls (machine2machine).
A script which will find random pictures of anyone in the family from the Immich database, resize them and add metadata on them like where they were taken and when and put them on the TV to show as kind of a screen saver when we're at home.
I like this Facebook feature which shows you "Today 10 years ago", Immich, does have it in it's UI too and perhaps I will mix in those pictures also to show on TV.

An alternative tool to Extract/Load data via YAML, Python or CLI.
I’ve created an AI-powered app designed to help candidates prepare for Meta’s product manager interviews, with a focus on product execution questions. The app allows you to practice by speaking or typing your responses, then uses AI to score answers against a rubric and track your progress over time.
I’m looking for beta testers—happy to share early access if you’re interested! If you are please message me.
Would this tool be useful for internships too? I work with students who are looking to interview for internship roles in PM
Yes I think it's applicable. Happy to chat. What's the best way to connect?
I am a bit of a checklist nerd, so I wrote a web app do to checklists: https://checkoff.ai
As it is fashionable these days, it can create checklists with AI ("Fun things to do in Pittsburg"), you can create checklists from templates (some stuff you do every day), etc.
I also have an MCP server that allows you to plug it into your favorite LLM.
I'm working on a super-simple budgeting app called https://4keynumbers.com, which is based on Ramit Sethi's Conscious Spending Plan. It currently syncs my expenses from Plaid and cooks it down into a single chart, with only savings, investments, bills/fixed, and "safe to spend" as categories.
https://buildfreely.com helping people build a shed or small struture.
Nice work! I've recently been modeling sheds in SketchUp both with and without the Framer extension and it can be really tedious.
Random question as I don't know a ton of framing... is your sample model missing jack studs on the large door opening?
Good observation. Yes, because the gable wall isn't load bearing so it doesn't have a load bearing header which needs jack studs.
cool

I’m at a crossroads with my Speed Cubing Competitions listing app (SCComps.com). It’s an iOS app built in Flutter, has around 250 downloads, and currently generates no revenue. I'm spending about $500 a year just to keep it running. There’s little community engagement, and I'm debating whether to double down and rebuild it in Swift—or just shut it down altogether.
Deterministic guarantees, and corrective behavioral monitoring for ai agents (starting with claude code, and ADK). Think security + performance bumper rails. At the cost of 0 context.

It is a DNS service for AWS EC2 to keep the ever changing IPs when you cannot use the Elastic IP like ASG or when you don't want to install any third party clients to your instances.
It fetches the IPs regularly via AWS API and assign them to fixed subdomains.
It is pretty new :) still developing actively.
Currently I've been working on https://terragonlabs.com which is a way to orchestrate Claude Code and other agents (Amp, Codex) as background agents.

LLM-Jail is a Simple Docker Container to Contain Your LLM CLI
https://github.com/codazoda/llm-jail
I don’t know if this is really necessary, but I created it after doing an in-house CTF challenge, with no LLM rules, and I was giving several LLM CLI’s a lot of leeway and iterating very quickly.
I'm working on Happy Coder, an open source Codex and Claude Code native mobile app (plus a web app).
Happy lets you spawn and control multiple Codex/Claude Code sessions in parallel. Happy Coder runs on your hardware, works from your phone and desktop, costs nothing, End to End encrypted, and permissive MIT License.
https://github.com/slopus/happy
Happy Coder is a unix style "do one thing well" project.
The goal is zero workflow disruption. I want to be able to run CLI coding agents on any internet connected computer, and control them with my phone. Happy has a command line wrapper for Codex and Claude Code that let you start a session in your terminal, and then continue it from your phone with real time sync. So type in your terminal and see it on the phone, type into your phone and see it in your terminal. So you can switch back and forth.
There is an optional voice agent some contributors have been hacking on that lets you talk to the voice agent first, and the voice agent then writes prompts for Codex/Claude Code and answers questions about what the coding agent running on your computer is doing/did. The voice agent feature is pretty neat, but in my opinion needs a bit more iteration, so any ideas or help would be awesome.

I like the UI, really cool project.
I think the prompting might need more work to make it natural though. I just tried a "hungover chat with 996" worker, and the responses seemed to be lacking a little too much context

How is this different than using Google docs or something ?
Scriptwriting require specific formatting (set by Hollywood ages ago). Doing this in google docs is really painful. Besides that, people who work in this industry are already used to the format, so if you wanna pitch something to studios, they expect to be in industry format.

Working on Wordspike.com which I launched earlier this month. It exists to help you extract information from videos so that you save time and get a text to work with. It’s freemium model.
I built Wikli (https://www.wikli.com/) - an AI-powered news aggregator that clusters articles semantically and generates daily digests with editorial oversight.
The Problem: News fatigue is real. Reading 50+ articles daily (from hundred of different sources) to stay informed is unsustainable, but traditional aggregators just dump links without context.
Wikli uses a three-stage pipeline:
Scraping & Processing (Cloudflare Workers): RSS feeds → content extraction → AI classification Semantic Clustering (Python): Claude groups related articles across sources into coherent stories Digest Generation: AI synthesizes clusters into readable reports with context and TLDR
Technical Highlights:
Cloudflare Workers + PostgreSQL for scraping infrastructure Hybrid content extraction (Readability + Puppeteer fallback for tricky sites) Claude Sonnet 4 for clustering and synthesis (outperformed embedding-based approaches) Theme-based filtering with relevance scoring (0-10 scale per article) Telegram bot with stateless approval workflow for editorial control
What's Different:
Semantic clustering beats chronological or source-based grouping Context from previous digests prevents repetition Human-in-the-loop via Telegram for quality control (can edit title/approve digest) Open architecture: separate Brief Generator (Python) and Scraper API (TypeScript)
Stack: TypeScript, Python, PostgreSQL, Drizzle ORM, Claude/Gemini APIs
The system handles rate limiting across domains, AI API throttling, and includes a DataManager abstraction for centralized data operations. Currently live in Italian at wikli.com - language-agnostic by design but focused on the Italian market for now. A the moment running with two topics (AI innovation and Inter Milano Football Club) via Telegram and wikli.com website.
Happy to get any feedback.

A tool for Muslims. Dreamstate: Interpret your dreams Islamically
https://dreamstateai.replit.app/
Traditional Knowledge: Constrained to Ibn Seerin's classical teachings — trusted by Muslims for over 1,000 years AI-Powered Analysis: Unlock the meaning of your dream with 4,300 dream symbols from the Dictionary of Dreams.
Share your dream confidentially, answer a few context questions, and receive your authentic Islamic interpretation in under a minute.
This is an MVP which I started <4 weeks ago. Currently validating Desirability, Feasibility, and Viability.
Confidentiality is very difficult to guarantee. You may want to put some brackets on what your users can realistically expect and give them tips on how they can stay anonymous. But lovely and novel idea, really neat to see these kind of cross-overs.
On the app's dream input page, it specifies a bit more "Your dreams are private and not stored or collected." - would that cover it? Thanks for your feedback and encouragement!
That is a 'pinky promise', it may well be true and let's assume you are well intentioned but it leaves the door open to you not being trustworthy after all or someone intercepting the data while it is being processed (for instance, by compromising your service).
In order for you to process the dream data you have to at least make a temporary copy. One way to get rid of that is to move the interpretation part to the client side if possible. Another thing you could do is if people are really concerned about the content of a particular dream to suggest they use TOR or some other anonymization (not perfect, I know) service to at least hide their internet location from you, the operator of the service.
Does the app itself run entirely within your own infrastructure or does it call out for part of the work?

I'm building a mindfulness app to help people set daily intentions and practice gratitude — https://www.justfortoday.app/
It’s a free app called Just for Today, inspired by a poem I found in How to Stop Worrying and Start Living (amazing book).
Download here: https://www.justfortoday.app/
It’s completely free. No ads. No account. All offline. Everything stays on your device.
The poem is a gentle reminder: - You don’t need to fix everything today. - You just need to be present — Just for Today.
That simple idea became the heart of the app.
Each morning, the app invites you to: - Set a kind intention - Check in with how you’re feeling - Practice gratitude - Write a little — just for you
If you try it, I’d love to hear what you think. Thank you :D
Trying to use Claude Code to crank out 100 free AI-less tools & apps. Hoping this will give me some decent passive income when I finally retire.
Tinkering with a tiny macOS app that gives me proactive reminders about the low battery and imminent shutdown.
Standard system notification comes at about 10%, and most of the time, in my case at least, whenever I miss that, the result is "laptop shutdown amidst an ongoing video meeting" or something like that. (Basically, too late before I act)
Just so that I don't miss the reminders, the app will show an overlay window with some text, following my cursor, and a custom sound.
I built a version this weekend, and am current doing a dogfooding exercise.

I'm working on a few things, but the one that's gaining the most traction right now in terms of users is kyoubenkyou
https://www.kyoubenkyou.com/
In short, it's a few things:
- JA->EN dictionary
- hiragana / katakana / time reading / number reading quizzers
- learn kanji with FSRS, anki-style
- vocab quizzer
- the coolest feature (imo) is a "reader": upload Japanese texts (light novels, children's books, etc), then translate them to your native language to practice your reading comprehension. Select text anywhere on the page (with your cursor) to instantly do a dictionary lookup. A LLM evaluates your translation accuracy (0..100%) and suggests other possible interpretations.
It's all elixir+liveview+postgres+pgroonga (though there are times when I would like to have SolidJS).
I've been considering open-sourcing it due to lack of commercial success, but might try an ad-based approach first.

Postply uses full-context to generate better replies on X, Instagram, Facebook & LinkedIn. It supports custom reply profiles and styles for support teams and social media managers. There are clearly a lot of AI replies on social media already, but they are really generic and bad. With Postply.com I'm hoping it will help people generate better and more meaningful replies.

In September, I was working on language core, console, generic methods, etc ... but this week I updated integration with OpenAI, IMAP, Surf (browser like client) and then I did few experiments by meshing together these libs.
These few lines proved to be quite helpful for my work email :)
I also tried to write/use these libs interactively: https://asciinema.org/a/745616and made a "console applet": https://pbs.twimg.com/media/G2FXUepWgAAn7cu?format=jpg&name=...

I've been working on LogChef (https://logchef.app) - a specialized log analytics UI for ClickHouse that focuses on powerful querying and exploration without the complexity of full observability platforms.
The core idea is to leverage ClickHouse's incredible columnar performance for log analytics while providing a schema-agnostic interface that works with any log table structure. It supports both simple search syntax for quick queries and full ClickHouse SQL for complex analytics. Also it has proper RBAC: Team-based access controls for multi-tenant environments.
Off late I have also added some AI features:
It's open source (AGPLv3) and deliberately doesn't handle log collection - instead it integrates with existing tools like Vector, Fluentd, or OpenTelemetry Collector. The roadmap includes REST APIs, client libraries, visualizations, and alerting.Built with Go + Vue.js + TypeScript. Currently handles millions of log entries daily in production environments at my org. The deployment is just a single binary deployment with a SQLite DB.
Would love feedback from the community! GitHub: https://github.com/mr-karan/logchef

Working on a original algorithm to explain human behavior from 3rd person perspective.
The whole research is divided into 6 stages. In 2nd stage, I want to use that to mathematically establish the best course of action as an individual.
In 3rd stage, I will explain common psychological phenomenon through the theory, things like narcissism, anxiety, self-doubt, how to forgive others, etc.
In 4th stage, I will explain how the theory is the fastest way to learn across multiple domains and become a generalist and critical thinker.
In 5th stage, I will explain how society will unfold if everyone can become generalist and critical thinker through the theory.
In 6th and last stage, I will think about how to use this theory to make India the next superpower, as this theory can give us the demographic advantage.
Shared more about the algorithm here https://x.com/admiralrohan/status/1973312855114998185

I'm writing a programming language for feature-flags/remote-config. I figure a simple DSL has to be an improvement over YAML or a series of forms in a web app.
I'm also generally disappointed by the lack of testing that's performed on feature-flag definitions. So I'd like to have a test runner capable of asserting your feature flag's rules matches your intent.
I’m working on yet another cloud based coding agent https://seniordev.io/ that connects to an existing GitHub repo, spins up a feature branch, commits incremental changes, and opens a PR. You can jump into an embedded VS Code server to review and tweak the code before merging—no local setup needed. Any feedback is greatly appreciated Thanks!

I recently published a book about coding, and put it all online for free: https://elementsofcode.io
I suppose it has moved from “what are you working” to “what have you worked on” territory, but since I wrapped up the website just about a week ago it still feels quite fresh.
Always interested in feedback and what folks find useful! It’s focused on the mechanics of writing understandable software, which I think is especially important in the age of AI slop.
just bought the milliondollargpt.com and have no idea what to do with it...
For now, I think it would be funny if you put plaintext that says "just bought the milliondollargpt.com and have no idea what to do with it...". Optionally as a hyperlink to your comment I am replying to.

done! thanks
Awesome! Thank you internet stranger!
thats make sense! just a sec :D
I have been prototyping a local-only social media manager initially targeting the game development community. I am sick of all the subscription only platforms such as buffer, hootsuite etc.
Initially I have been looking at Mastodon and Bluesky since they have sane APIs.
The plan is to make it so that you can sync your data folder either manually (e.g. dropbox, or sneakernet if you want) or a via a basic cheap data plan.

Introducing My Latest Project: An AI Interview Assistant for Job Seekers
So, I've been working on something... interesting. It's an AI assistant that can actually represent candidates in the first round of job interviews. Yes, you read that right—because apparently, we've collectively decided that showing up to your own job interview is so last decade.
Here's how this magnificent creation works: The system ingests everything about a candidate—CV, professional experience, cover letter, LinkedIn, GitHub, portfolio, and any preferences they've specified (salary expectations, location, contract type, the usual existential career questions). Then, armed with this treasure trove of personal data, my AI conducts automated interviews directly with HR departments or their equally soulless chatbots.
In real-time, it generates responses as if the candidate themselves were speaking—complete with soft skills, communication style, and structured answers. Because nothing screams "hire me" like algorithmic authenticity. If it encounters a question beyond its training data, it politely pings the candidate: "Hey, need some input here before I completely botch your career opportunity."
What this technological marvel offers: 24/7 Availability – Candidates can "attend" interviews while sleeping, working their current job, or contemplating the futility of modern employment practices. The AI never sleeps, never complains, never has a bad day.
Personalization – Responses tailored to each candidate's actual experience and skills. It's them, just... optimized. Debugged. Free of human error like nervousness or accidentally mentioning you follow your passion for underwater basket weaving.
Performance Analytics – Post-interview analysis of how well the candidate matched job requirements. Because self-awareness is overrated—let the machine tell you how you did.
Training Mode – Candidates can practice various interview scenarios and get feedback. Think of it as rehearsing for the day when neither interviewer nor interviewee is actually human anymore.
And yes, the circle closes beautifully.
I'm building a system where AI talks to AI about human employment while humans... what? Watch Netflix? It's efficient. It's scalable.
It's absolutely ridiculous when you think about it for more than thirty seconds.
But hey, if companies are going to screen candidates with automated systems and generic chatbots, why shouldn't candidates fight fire with fire?
Welcome to the employment arms race nobody asked for. I'm either solving a real problem or hastening our irrelevance. Probably both.
Yet another online cycling calculator, this time with an emphasis on power/speed difference between different tires.
I'm sick and tired of audiophile level bs floating around online forums and I want to create a simple tool for people to fiddle around with different settings to see what really impacts their speed while cycling.
As usual - no plans for monetization whatsoever. Nothing fancy either, just an elaborated weekend project.

Esperanto havas la mal- prefikso por krei specialcelan antonomion, sed la rezulto ofte mankas klarecon, kaj kiel morfemo mal mem estas morale kondamna: komparu malica, maligna, malversacio kie mal ne estas sinkrone disigebla.
Tial mi vorkas por krei liston de ĉiuj mal- vortoj kun sen mal- alternativoj. Fakte ĝi ankaŭ povas servi la kontraŭan celon, provizi pli ĝeneralajn mal- vortojn kiam oni deziras krei verkon pli facile akirebla de ĉia nivelo.
Mi planas eldoni ĝin denove ĉe https://eo.wiktionary.org/wiki/Aldono:Pri_antonimoj kiam mi finis, sed nun estas pli facila progresi per citilaj kaj vidŝangaj kromaĵoj ja provizata ĉe https://fr.wikiversity.org/w/index.php?title=Utilisateur:Psy...
