I am about to begin a PhD in astronomy. Until last month I was working at Caltech for 3 years on code which calculates orbits of asteroids to high precision. This code is being used on several NASA telescopes now to predict when they will image known asteroids (NEO Surveyor, SphereX, maybe Roman eventually). I was allowed to open source it and I am planning on making it the basis of my PhD research:
It can predict the location of the entire catalog of known asteroids to generally within the uncertainty of our knowledge of the orbits. Its core is written in rust, with a python frontend.
I've never really dabbled in youtube. I have several projects/papers I am working on using this code, I have thought about writing some blog posts as I publish those. But a PhD is going to be a major time sink, we will see what happens.
Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree.
The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side).
I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping them back to their original state, but in an order that does not intersect other branch vectors.
The idea came to me as a particularly difficult tree needed to come down in my friends yard, and we spent hours planning it out. I've already gotten some interest from the tree-surgeon community, I just need to appify it.
Second rendition will treat the problem more as a physics one than a graph one, with some energy-minimisation methods for solving.
Funny, one of mine also involves trees -- but is mostly outdoor cleanup. The kind that involves decades' worth of it, thanks to what I'll just say is a lot of maintenance that wasn't done over a long time. There's an extensive amount of brush, leaves, etc of varying ages that could maybe be shredded up into something useful, invasive vines I'm still trying to deal with, and more old trash than I've fully figured out how to properly dispose of.
It's turning into various DIY rabbit holes, actually, with the next one (outside of various related landscaping stuff) being to gut a basement.
Do consider the value of the wood in relation to your cuts. A well-placed cut not only guarantees safety but will also take the maximum board feet from the tree.
i work a lot with NVEL for this. one time even tried porting nvel to wasm for fun and client accessibility. we "virtually buck" trees which seems like could be applied to your proposed use case. if op wants to go down this path: https://github.com/FMSC-Measurements/VolumeLibrary/tree/77d4...
This is the kind of thing that makes me love HN. An idea I would never have thought of, with an immediately obvious use in multiple ways (fall path plus ideal lumber cutting?), probably very difficult, yet being tackled with one implementation already... and spoken of quite humbly.
I was imagining something like this for pruning fruit trees — something to help noobs like me see how to put pruning guidelines into practice on a real, overgrown tree. Good luck!
Where I live this could be very helpful becuase people is too, how to say it, maybe ignorant in safety and logic specs. Also could be usefull to know or estimate what tree are in a innminent or highr posibilities of fall with wind.
I was mixing methods, sorry. My initial rendition for solving the cuts would initialise a somewhat sparse network from tree to ground, and solve for non-overlapping paths.
This became convoluted and I just opted for a far easier method of solving vector intersections.
Its also not perfect since I haven't factored in rotation origin very well, and I'm now pursuing a far simpler physics-based approach
Working on a browser extension to make it easier to find content on YouTube that fits your interests.
I watch a lot of YouTube videos and have found it very annoying that YouTube latches onto one or two topics that you've watched and only recommends that type of content over and over again. Even if you use their "Not Interested" tool, not a whole lot changes in your recommendations.
At the end of last year I launched Relevant - a crowdsourcing website where users can categorize the channels they watch into a defined hierarchy of categories ranging from broad topics like "Science" and "Gaming" to more specific ones like "Phone Reviews" or "Speedrunning".
Although I've had good feedback on the website, engagement has been relatively low and I think that's because it's a big ask to have someone navigate to the website to find the content. This year I decided that I'd bring the content to them by making a Chrome extension that lets users interact with Relevant directly from within YouTube.
It's still a work in progress but I'd love to get a first version out within a month or so to start spreading the idea and gathering feedback. If this is of any interest to the people here on HN then please let me know what you'd like to see most on your feeds.
I’m working on Popgot (https://popgot.com), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials.
On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging peanut butter with BPA by checking every photograph of the plastic or avoiding palm oil by reading the nutrition facts) or brand lists (e.g., only showing WSAVA-compliant dog foods). Still reviewing results manually to catch bad extractions.
Started this to replace a spreadsheet I was keeping for bulk purchases. Slowly adding more automation like alerting on price drops or restocking when under a threshold.
I like this idea a lot -- feels like there's a lot of room to grow here. Do you have any sort of historical price tracking/alerting?
And/or also curious if there is a way to enter in a list of items I want and for it to calculate which store - in aggregate - is the cheapest.
For instance, people often tell me Costco is much cheaper than alternatives, and for me to compare I have to compile my shopping cart in multiple stores to compare.
Colibri—a self-hostable web application to manage your (and your family's) ebook library, intended as a companion to Calibre. I want it to be a friendly, simple, capable, opinionated app to review your books, add metadata to them, get them onto your reader, share them with family and (few) friends, create a public shelf for bragging, connect with Goodreads etc., and exchange comments and reviews on books.
This is explicitly not intended to ever be monetised, and I enjoy all the implications that has on the design. Colibri is as much a tool I personally want to use, as it is a study in small-audience user interfaces, and the quest to build the perfect book catalog schema.
I'm looking for fellow book-loving people to work on Colibri, to create the best personal digital library possible. If you're interested, feel free to reach out via email (in bio), or on GitHub.
A fan chiming in. I'm really happy someone someone is tackling this and it's looking good. One thing: can we get a demo instance just for initial snooping? A screenshot or two is fine but to get a feel for features it would be nice to have something (even heavily limited) we can just interact with?
That's the first thing I'm going to do as soon as it's possible! I recently refactored the code base to a monorepo, and still need to make some adjustments so it'll run stable again. Stay tuned :)
Ooh, this looks fantastic. I'd love to help, but I'm spending almost all of my off-work hours looking for jobs right now. Maybe I'll find a good one sooner rather than later...
Working on Taskade (https://www.taskade.com), building the execution layer for AI collaboration.
Taskade started as a real-time workspace for teams to organize projects and ideas. It's evolved into something bigger — a platform where humans and AI work side by side.
We’re moving past simple chatbots into real agentic workflows, where teams can generate structured task lists, mind maps, and tables, train custom AI agents with dynamic knowledge, and automate work from start to finish.
Today, Taskade is built around three core pillars: Projects, Agents, and Automation. It’s like giving your team a second brain that can think, plan, and get work done across projects, automations, and real-time collaboration. If you’re interested in the future of human-AI collaboration, take a look!
I'm still tinkering on my multiplayer game server framework when not grinding away at my day job.
The idea is essentially: An Erlang-based control plane, supporting ENet and WebSocket connection modes, with Protobuf for messages. Erlang has an excellent concurrency story, and I think it's a great fit for game servers. I've wrapped up a bunch of this work into behaviors on the Erlang side, such that developers can target the "gen_zone" behavior (for instance) to implement a tick-based game server. I'd like to expand that into other types of games, such as turn-based games.
I've also got a Godot plugin for generating a client library based on your protobuf schema. The plugin handles session stuff, exposes functions for client-to-server messages, and emits signals for server-to-client messages.
These days I'm working on integrating Luerl (Lua in Erlang) and Love2D support. I want to be able to take advantage of Erlang on the back-end while writing the majority of game logic in Lua. Further down the road I want to explore hot reloading parts of the Lua game state on the client/server, perhaps with an in-game editor, to develop the game "inside-out", in a way.
I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and started working on My Sukari as a platform of free tools for diabetics.
I mostly get time to work on it on the weekends, so it's not yet ready for public use, but I've fully fleshed out one of the main features: Sugar Dashboard - A dashboard that visualises your Glucose data and helps you easier analyse it.
I'm really passionate about this and getting as much free, practical tools in the hands of patients (it honestly shouldn't be this hard to manage a disease)
All types.
The sugar dashboard allows import of data from different glucose apps, so its goal is to allow you visualize and analyze your data. I hope to integrate with cgms directly if I get some that allow it, and also source from Health connect. Sharing with specific people eg doctor is also a big ask that I'm working on.
The other WIP tools will be fore general health, not just diabetes, like carb counting from a photo via AI
Also recently diagnosed and just open sourced how I'm using AI to count carbs + get insulin doses [1]. Biggest issues I've seen to starting a legit business is not having sanctioned access to real-time blood sugar values (the APIs are all one hour behind), and dealing with the FDA. Love the idea of more tech-enabled diabetes management, good luck!
Love this! Thank you for sharing!
My backend is also in Go so this is a godsend. Will see how I can incorporate and let you know if I do!
> not having sanctioned access to real-time blood sugar values (the APIs are all one hour behind)
Ah, I didn't know this. One of the prospective tools I had in mind was real time alerting in case of drastic drops eg ping doctor or relative. I think will have to be limited to the apps/tools that do support realtime.
Technically there is unsanctioned access (someone reverse engineered the real-time APIs [1] which I ported to Go). I think the FDA does not want easy access to real-time values so that folks can't easily recommend insulin dosing without oversight. I am personally of the opinion that it is our right to have programmatic access to the real-time data and do with it what we please.
Would love to get in touch to hear more about your long-term vision for the project!
Thanks!
I started out with a Nextjs full stack on Vercel, with db on Turso but ended up with a React frontend (next on vercel) and Go backend (selfhosted on vps).
Decided to port the backend to Go + postgres (on a Hetzner VPS), and retain the frontend on Nextjs - A lighter weight client, moving most of the compute to the backend API.
Few reasons for the port: I've had a lot more success/stability with Go backends, Turso pulled multi-tenant dbs which is what I mostly wanted them for, Nextjs is getting too hard for me.
Go backend is just the std lib (1.22+ server with the nice routing) - I mostly write all the lines in this
Frontend is textbook modern react: React19,next15,tailwind4
- AI mostly writes the code in the frontend (Cursor + Cline + sequentialthinking + context7 + my own custom "memory bank" process of breaking down tasks). AI is really, really good at this. I wrote this https://image-assets.etelej.com/ in literally 2 days 2 weekends ago with less than 10% of code being mine (mostly infra + hono APIs)
I launched Foqos here a few months back: https://github.com/awaseem/foqos and just working on the feedback. Since then added QR codes, breaks, ability to block apps manually and even a mini redesign. It’s been a ton of fun so far!
The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it.
You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.
Entirely offline & no usage of AI. Free in-browser version (using PGLite WASM), paid desktop version.
This would be incredible to understand why some queries execute slow; most of the time it's one of the steps in between that takes 99% of the execution time at our company. Do you record the time each step takes?
This is awesome! I’m work with a team of analysts and data engineers who own a pretty big snowflake data warehouse. We write a ton of dbt models and have a range of sql skill levels on the team. This would be the perfect way to allow more junior devs to build their skills quickly and support more complex models.
I would recommend you target data warehouses like snowflake and bigquery where the query complexity and thus value prop for a tool like this is potentially much higher.
Thank you, nice to get some idea validation from folks in the industry. For sure data warehouses are the top priority on my TODO list, I picked PG first because that's what I'm familiar with.
I can ping you via email when the debugger is ready, if you're interested. My email is in my profile
Thanks! Would you mind sharing what would be your use cases?
At my job, all of our business logic (4 KLOC of network topology algorithms) is written in a niche query language, which we have been migrating to PostgreSQL. When an inconsistency/error is found, tracking it can take days, manually commenting out parts of query and looking at the results.
For now, yes, but I'll start working on adding support for all other DBs (especially OLAP) as soon as possible. The geberal approach is the same, I just have to handle all the edge cases of the SQL dialects
I am working on the sunflower plant density estimation problem. The goal is to be able to estimate the germination rate as early as possible. Farmers benefit from such information, because:
- there are lots of expenses still to be made (fertilizer, pesticide, salaries), which may not be worth it if germination is under certain threshold
- if detected early, there is still time to plant another grain or to fill up the missing plants (requires precision seeders and seeding maps)
- is a very good proxy for yield estimation (farmers often trade futures even before they have harvested)
For the purpose I have created a dataset (a collaboration between my employer and Sofia University) and published it in order to enable scientific collaboration with other interested parties. Still working on the dataset annotations.
Interesting, I'm also involved in a project to do yield prediction, but with a ground-vehicle with camera's on top to drive between strawberry and blueberry plants.
Yield prediction is huge indeed, because overshooting your prediction means seller stuff for a lower price. Undershooting means paying for someone's product to make up for the difference. Probably there's quite a bit of matchmaking in between those under and overshooters and someone making a good buck out of that too.
So many cool technical projects here. But I am doing something completely different - masonry. Repairing walls in 3 rooms. It includes reinstalling dozens of falling off bricks, installing 30 or so power outlets, replacing old windows with bigger modern ones, fixing openings for the doors and plastering everything afterwards. On one hand it’s interesting, because it’s very different from the dayjob. But doing it by myself pays my newish car in cash immediately. However I wouldn’t do it for money somewhere else, it’s really really hard work.
Instead of masonry I would like to work on time of flight cameras. But the day has only 24 hours :-(
I launched my web-based notepad calculator, https://numpad.io/, a few years ago.
Right now I'm working on a version 2 that has user accounts, multiple documents, markdown support, and document exports. Everything is local-first and it uses CRDTs to sync documents.
It looks like this: https://i.imgur.com/Plk1DQ4.png the calculator is mostly the same for now, with a few improvements. It's unstable right now, so I don't want to publicise the dev url, but if you'd like to become a beta tester email me at contact@numpad.io
Creating a modern development environment for win98. Currently I’m working on a git client. I have no patience for learning C. So backporting git is not an option. I also don’t want to use cygwin. So I’m using a server to expose git as http endpoints and coding a git client in php to use in msdos. I have Vim 7.3 and and gnu coreutils working in msdos already. So soon I will have a very nice dev environment. I want to create a one click installer which gives you xampp, vim and then all the tooling I’ve created. I’m also interested in creating SPA that works in IE5.5. But I’ll do that when my tooling is ready.
A Prolog TUI library that sticks to relational/logical programming, is conceptually simple, complete, and performant.
Only requires some core ansi features that exist or are easily implemented in most Prologs.
Currently have stuff like nested scrollable areas, toggles, frames, buttons, layouts working.
Also, a visual programming language implemented as a PICO-8 script, where the "programming" is done fully in the sprite editor.
It tried out vibe coding this weekend. I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.
I hit an OpenSearch bug this week where you can't get any browser based requests to work. Its due to zstd becoming a standard part of Accept-Encoding and OpenSearch not correctly supporting it so I wanted to install a browser plugin that modified the browser HTTP request headers to my servers.
I don't know about everyone else but I love that browser plugins are possible but I hate having to find them. Its mostly due to never knowing if you can trust a plugin and even if you find one, you have to worry about it being bought out in the future. With vibe coding I was able to build a browser extension in 45 minutes that had more features than I originally planned for.
I spend more time documenting the experience than building which is wild. If you are interesting you can look at the README in https://github.com/mattheimer/vibe-headers
But I left the experience with two thoughts.
Even seasoned developers will be using vibe coding in the future.
I think in the near future the browser plugin market will partially collapse because eventually browsers will build extensions themselves on the fly using natural language.
In my experience, "vibe coding" can produce a rich prototype very fast.
Then as scope expands you're left with something that is difficult to extend because its impossible to keep everything in the LLM context. Both because of context limits and because of input fatigue in terms of communicating the context.
At this point you can do a critical analysis of what you have and design a more rigorous specification.
I don't disagree but context limits are expanding rapidly. Gemini 2.5 Pro which was used here has a 1 million token context window with 2 million coming soon. Cost will be a concern but context size limits will not.
Totally agree, I mentioned it in another comment but Gemini was a game changer for allowing me to increase the size of the project I can feasibly have AI work on.
Only issue is Gemini's context window (I've seen my experience corroborated here on HN a couple times) isn't consistent. Maybe if 900k tokens are all of unique information, then it will be useful to 1 million, but I find if my prompt has 150k tokens of context or 50k, after 200k in the total context window response coherence and focus goes out the window.
I'd love some more innovation on increasing context size without blowing up RAM usage. Mistral small 2503 24B and Gemma 3 27B both fit into 24GB at Q4, but Mistral can only go up to about 32k and Gemma about 12k before all VRAM is exhausted, even with flash attention and KV cache quantization.
But my reading is that the parent wouldn't have tackled this at all without the vibe coding, and would have used an off-the-shelf extension. So in that case, it's a pure win, no?
Yeah I could have framed it better. I was responding to:
>I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.
In my experience most things that aren't trivial do require a lot of work as the scope expands. I was responding more to that than him having success with completing the whole extension satisfactorily.
That's a difficult question to answer because I don't know if I'll grow the extension in the future. Only time will tell.
After I completed the extension I did try on another model and despite me instructing it to generate a v3 manifest extension, the second attempt didn't start with declarativeNetRequest and used the older APIs until I made a refinement. And this isn't even a big project really where poor architecture would cause debt.
Vibe coding can lead to technical debt, especially if you don't have the skills to recognize that debt in the code being generated.
I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+).
In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession
I have just created an account and tried to use the app; either I am dumb (at this hour), or the app has a very not intuitive UI :-)
I (think I) managed to create an expression, but:
1. it takes forever, I don't know what it's doing and it's still not done
2. I have no idea how to use it, onward
3. does not seem that I will be actually able to use it, as the app requires to be subscribed to use it...
Looking forward for a how to use manual / page + a real trial period. If the app requires a subscription with this UX experience, I will be gone :-)
I am the first to admit that the UI does not make sense to people who have not seen it in use. I have done some user onboarding sessions where you just “let them ask questions and click” and it goes terribly if it’s any consolation, I have never gotten that feedback after showing people how to use it (quite the opposite actually!)
Wrt to the expression, all expressions created today succeeded, so if you’re still seeing a progress bar let me know as that’s a bug. It’s possible something failed with the live updates, or it does take several minutes to create an expression (depending on servers, it can take up to 10 minutes at times, although the typical timing is 2-4 minutes depending on the expression)
If you click on any of the review methodologies, it will start reviewing any of your successful expression. From there, the experience should be a lot more explorer-friendly :)
What it’s doing is: analyzing the sentence, splitting it into phrases, aligning it across all languages, tagging all of the gender/case/tense/etc, researching pronunciation, generating audio, aligning the audio, prioritizing the words (across several axes), and generation explanations/dictionary for each individual word
The UI was a little unresponsive on mobile, and when I opened the "Media" page on desktop I got multiple block rendering errors. Opening the console reveals a syntax error (missing ] after element list) and some type errors.
Also, it looks like you have to get the subscription to use it in any way? It's hard to gauge whether it is for me or not if I have no way to trial it. I found the UI a bit confusing too, I was not sure what I was supposed to do after logging in. As another commentator mentioned, it's asking me to set a reference language but I see no way of configuring it.
Block rendering errors on the media page is new to me. I will look into it.
The reference language error should not be shown (I mean it’s not incorrect, but there is a “no expressions error” that should take precedence).
A video is coming :) I didn’t expect so much interest from a comment in this thread. If you get in touch, I can walk you through it personally, otherwise check back in a couple weeks and there will be a video overview.
Learning Latvian through Anki flashcards, but it's not well supported by the main platforms, and there's not a huge amount of content out there for learning.
This alongside a couple of the usual suspects.
As a side note, on a Pixel 4a 5G (old phone , but functionally not ready for e-waste) the homepage bleeds all over. Some components into each other, others off screen. Might want to check that.
Oh no, the website is brand new, it should be working everywhere. I'll have to dig up an older android, I should have one somewhere.
Languages below, if you know their alpha 3 code. Currently having some issues with Thai and Zulu though, so they're temporarily disabled until I have time to fix them.
I have not ~tested~ verified it for Latvian, I would be curious to hear your thoughts. It has been working pretty well for Maltese, Albanian and Macedonian though, which should be lower resource than Latvian!
As mentioned elsewhere, the first time user experience is abysmal. If you reach out though we can hop on a call and get you set up - or in a few weeks I'll have a video done and up. In the meantime, you should be able to create an expression (in the nav bar for desktop and mobile) fairly intuitively.
Since you're in Amsterdam, I'm curious how well you think it performs for learning Dutch? I'm a native English speaker with a B2~ in Dutch and just looking to progress more. I've not used spaced repetition up to this point in my learning journey (almost 3 years).
It does really well, 95% of the time. The application was built to jump in at any levels - find a movie you want to watch, align the subtitles, see the most important words, create expressions with words you don't know, and the SRS should focus on the words most important to you.
For my Dutch (which was probably once a high B2, now probably a low B1) I only use the audio review when walking my dog or cooking. It plays the audio of the cards in a playlist, so I practice hearing and repeating them.
It's not so self serve at the moment, but if you get in touch I can get you up and running.
I was quite eager to check this out. As some polite feedback, a few things turned me off quite strongly:
1. I want to get confirmation that the language I want is covered (Hungarian). "120+" doesn't confirm it for me, as Hungarian seems fairly rare for language apps. Can we not just have a "search your language" field?
2. I need to see what the app actually looks like, how it proposes it'll teach me.
I'm one of the eager-to-pay people, because Duolingo is frankly dogshit (ok. Mostly polite) at teaching languages (doubly so ones that it doesn't care about like Hungarian). But I'm so suspicious of language apps, due to being burnt a dozen times.
Thanks for the feedback! I agree with you completely.
1. I just started the marketing website a few weeks ago, and if you can believe it, I didn't readily have that information. One of my tasks last week was to compile a list of languages that could work, write some tests for all of the languages, and get a list of supported languages. I have that list now, I just need to put it on the marketing page.
2. As mentioned in other comments, I'm working on a video. I'm preferring to fix glaring issues before making the video, although at this point I'm verrrrrrry close. I have started scripting it, but it takes a lot of time to make a good video (1-2 full days if I don't want to edit it).
Your feedback is completely valid, and they're both reasons why I'm not really marketing the product yet. This thread seemed like a good middle ground though as having some people using all the languages would be really helpful. Also, I've genuinely been loving using it and want to share.
It's just me working on it, so these things are coming, but everything takes a while! Hopefully these didn't sour you on the project permanently :)
Nope, not soured. And don't worry, I totally get that things take a bunch of effort and time (doubly so as a solo project). I'll give it a re-look in a little while :)
i signed up and tried to use it. The UI is very confusing. i couldn't find the place to setup what language i want to learn and what language i know (for translation). It is best if you can have a video or images documenting how to use it.
Agreed. I’m getting close to a video to put on the landing page, probably some time next week.
The first time user experience is really bad, but the app itself makes a lot of sense once you see it in action. Feel free to get in touch with me (there are several methods listed when you log in) and I can give you a personal introduction!
If not then check back in a few weeks for a cool video :)
Yes, please. I've been looking for something like this. Lately I've been just casually going into another language with ChatGPT and asking it to correct me. I do I like some of the old languages, things like Aramaic, which just have a different feel.
I signed up, but now it's asking me for a "reference language" (which is a little ironic because it tells me this in English lol). I guess I'll play with this later.
Start by creating some expressions ("create" in the nav bar) and you should be able to play around with it. If you want to learn more, please get in touch. As mentioned elsewhere, I'll be adding a video tutorial soon (probably not this week, but sometime next week if all goes well).
Would love to get feedback on the old languages! It's been really good for the minority languages I'm learning
A note taking app - I know, I know, been done a billion times. But really, no software I’ve found works the way I want it to, so I’m just trying to write my own, starting with a front-end agnostic core and a TUI.
If it strikes a chord with anyone, I’d love to collaborate! The concept is centered around organization bubbling up naturally from dumping info in with tags, and “typing” your tags so that when you go to a tag’s page, the layout is customized based on what it is - a project, person, etc. A project could have all relevant tasks and notes listed, whereas a person might have name, contact info, etc.
Expanding some - the tags concept is similar to AnyType[0] types, but the rest of the software I’m writing is more oriented towards dump-first, tag, and let it sort itself out, whereas AnyType requires careful management and configuration of the workspace.
Been a freelance dev for years, now going on "sabbatical" (love that word) imminently. Just moved to reduced hours, still in the transition and unwinding phase.
Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things.
Depending on how long you're planning on sabbatical-ing, you might consider applying to the Recurse Center [1]. It's basically a (free) 6- or 12-week self-directed learning program that you do with others.
I had done a half batch last year and really enjoyed the experience.
25 years of experience including FAANG. Recently got divorced (complex litigations, fought hard, very satisfied with the outcome).
Now rethinking myself. Want to do something useful for humankind in the rest of my life. Having big ideas for the future. Trying some research-focussed 'side' projects. Considering writing a book. Learning new things. So on.
As a freelance web dev who also has an Airbnb side hustle, I got tired of expensive bookkeeping for a few transactions per month. I tried DIY, but my time is worth more than that.
Most importantly, both pros and DIY got subtle things wrong and caused me to miss out on thousands of dollars in deductions and credits.
So I’m making an AI bookkeeping chatbot that will handle all that for me. The aim is full automation while surfacing tax deduction and credit opportunities throughout the year. Like wouldn’t it be awesome to just have the research and tax credit or do home office deductions with zero effort?
At the end of the year, Kumbara puts together a series of financial reports that you plug into your tax software or hand to your CPA.
Working hand-in-hand with CPAs and some platform partners on this. Would love to hear from other solopreneurs or engineers who want to help build the future of financial freedom.
A minimalist, text-based memory system designed to naturally store and recall important events. It emphasizes simplicity, portability, and human-friendly structure by using six optional fields: who, what, when, where, how, and thing. These fields capture factual context clearly, deferring interpretation for later use or analysis.
I hacked my old kindle and turned it into a eink dashboard for my daughter’s school! Now planning to enahace it a bit further and make it easy to customise.
Creating stealth group in a huge Fortune 500 company with the blessing of my immediate boss but no other higher-ups. Trying to productize critical consulting tool sets in the utility industry so we can stop repeating ourselves for the 100th consulting engagement.
Yes, customer is a special snowflake but they still need 90% or whatever every other client in this industry needs.
Feeling increasingly like this is a fools errand.
Even though we've proved this out with tool sets strung together with duct tape and safety pins, and are therefore the most profitable group within our department, we still need to be 100% billable.
It's only because we're the most profitable group that we can pretend we're all billable while I work with two other people to bootstrap this crazy project
Edit: anyone hiring? Just found out my boss is quitting.
Oof. This post started so good and then got progressively more sad until the edit nailed it home. I hope your story continues and works out as a huge win, either as a new, good boss, you getting to openly lead this kind of thing, someone reading this and poaching/sponsoring you, or maybe even you working on this under your own name.
It was not intentional but my post really does read like a little story vignette that ends with a gut punch.
Not looking for sympathy so much as fellow appreciators of irony and schadenfreude but here's another kicker.
I pitched this idea to my previous company and was told there was no appetite for it. Just saw on my old company's blog that they released a "digital transformation in a box" program for mid-market clients in this space which is 90% of what I pitched to them. Bad and hilarious timing all around.
Last year I bought a broken jukebox. I wanted to convert it to be powered by a raspberry pi. I wanted it to work like a traditional jukebox where you used the buttons to input the song number. While there are a few existing projects to convert Jukeboxes to run from raspberry pi, most of them used a touch screen or didn't work well on RP5 which is what I had or the current version of raspberry pi os.
So despite not being a programmer, barely knowing a little javascript, and nothing about python, linux, or gtk, I was able to use AI to muddle my way through to creating a program that takes the input from a numpad, looks up the song from a list, sends it to mpd, and posts a picture from the album art embedded in the music file. https://github.com/jccalhoun/mpcButtonJukebox
An eBook sever on raspberry pi running nodejs. I had a lot of issues with iCloud not being able to download my books, plus my entire library is almost 1 GB. So, my solution is to serve a list of PDFs over node and allow download of a specific page range.
Reverse typesetting: reflowing page layouts where you don't have knowledge of the typesetting structure, i.e. a scanned physical book or PDF paper. Naive rules-based heuristics based on the dimensions of bounding boxes and gaps. Point is to reflow things for resizing to eink readers. (Specifically the size that fits in my pocket which I carry around. User #1 is me). Building in Common Lisp and targeting an Emacs mode for interactive execution with manual feedback.
You're inferring the structure of the document from the printed result. If typesetting takes a set of layout directives and outputs a page, this is taking a finished page and guessing what layout directives could create it. Then you can take that inferred structure and reflow the page in a new layout.
The reason I'm not falling back on OCR is because the general case is full of things, like math equations and inset graphics/diagrams, that can't be OCR'd. The only robust way to deal with those is to treat them as graphical atoms: "this bounding box can be moved around, but should not be split up into pieces".
PodSnacks (https://podsnacks.org) — Personalized AI summaries of top podcasts, delivered to your inbox.
I've been building PodSnacks because I found it overwhelming to keep up with podcasts across tech, business, and science. PodSnacks uses LLMs to summarize the most popular episodes from shows like Lex Fridman, Acquired, All-In, Invest Like the Best, and more.
You choose your favorite shows, and we email you short, high-signal summaries — no audio to skim through, no endless backlog guilt.
So far:
126K+ episode summaries generated
92K+ hours of podcasts processed
48–50% open rates
2,900+ early users
Still iterating and adding features like bundling by theme, language translations, and audio feeds.
If you're the kind of person who wants more inputs without more noise — would love for you to check it out.
What are the costs like, for such a service? You have to spend for transcribing (even if you ran something like Whisper) and pay for APIs to summarize, correct?
any way to expose api access for the keyword search feature? would be cool to build this into some topic summaries delivered via email I'm building for my team
I’d prefer summaries of my YouTube subscriptions, where I can also add my own “summary template”
In currently have a prompt for it that works for me, based on the transcripts.
Problem: too much duplicate information in any type of publication and too much fluff
Problem2: YouTube/transcriptions
Probably wouldn’t pay for such a service, but would be very happy using it. Perhaps some channel promo / email based ads for discovery or recommendations.
A simple coffee shop app that shows the nearest coffees shops that are closest to you. Using Google's AI, each shop has a Gemini AI overview that describes the shops offerings and other information that might be useful to the user.
I've only built it for Minneapolis and Chicago for now.
I am working on a super mario land re-implementation for game boy using C. It's made with the GBDK toolkit so the ROM can be run on a gameboy.
Currently the scrolling and background collision has been implemented, I am working on drawing the enemies... their is still a long way to go.
As for why I am doing this is nostalgia and fulfilled a childhood dream
repo at https://github.com/odrevet/marioland-gbdk/
I'm building a simple web-based drawing app for home sewing patterns. It's a little bit CAD and a little bit sketching tool. Born of my desire for easier and 100x cheaper home drafting tools. The app is still quite early (adding Bezier tools today) and the core workflow is not functional: of draft, lay out, print, repeat, only draft is working. But one step at a time! https://github.com/twaldorf/flatland-client
I'm in the midst of a tectonic career shift, from being laid off from a position and place I loved, to another gig while I keep looking for another unicorn role like before.
So most of my project work is home-based, after years of being able to chase (and execute) dreams at work.
On the technology front, I'm finally investing in a proper network core for home. WiFi 7 AP, 2.5Gig core, PoE everywhere, zone-based firewall. Still mapping out DHCP scopes and VLANs, but once that's done it'll be moving on to proper IoT and Home Assistant build-outs to prepare for the Unfolded Circle 3 later this summer. Also looking to redo my two N100 hypervisors off Proxmox and back to RHEL + Cockpit, or some other Linux + KVM implementation; from there, it's all about Kubernetes, Ansible, and Terraform. Really just a lot of oft-postponed side projects because I had amazing fulfillment at work, that I suddenly have ample time for now.
Outside of the tech stuff, I'm still trying to get some decent photos of two local birds of prey that have been hunting in my neighborhood. They seemingly spite me by only showing themselves when I don't have my camera with me, but dangit, I will photograph them.
On the writing front, I've got a few topics jostling around in drafts: speculating on potential futures of LLMs, the internet as a psychohazard, and a series of "fundamentals" to try and teach my non-techie circles more about how computers and the internet work, so they can do some modest self-hosting and get off centralized services. I'll likely dovetail some of them with my own home projects, writing them alongside the documentation as I make progress.
> This weekend I’m working on mobile app that allows you to upload photos and it turns everything into a stitched anime (ghibli or not) with movements and eventually sound and script. Great to make mini animes from your day or travels or anything.
I vibe coded the above including everything: code, design, logos. Just did it solo. It has all error handling, video generation notifications (it takes a while) and credit system. I myself can't believe it's been done in a month with AI. It's already in closed beta in iOS and android app stores. Let me know if you want to try it out before public release.
My quoted comment above was 28 days ago. This is working on this part time and with a family.
If you’ve used H3 or S2 it should be familiar, the major difference (apart from the fact it uses pentagons) is that the cell areas are practically uniform, whereas alternative systems have a variance of around 2 between the largest and smallest cells, making them less useful for aggregation. The site has many visual demos, e.g. https://a5geo.org/examples/area
The cells being the same shape is useful in some use cases and irrelevant in others. For example, see the Airbnb demo: https://a5geo.org/examples/airbnb. The H3 tiles are very different sizes in the two cities, and make it appear that there is a much higher density of listings in Malta, even though that is not the case.
However the symmetry of H3’s hexagonal cells lends itself well to flow analysis, or routing - which is no surprise as it was developed at Uber.
As for the name, it follows the convention of S2 and H3, which come from group theory and refer (loosely) to the symmetry groups of the various systems
No, it is based on applying a lattice onto the faces of a dodecahedron (technically a pentakis dodecahedron). Take a look at https://a5geo.org/examples/teohedron-dodecahedron and other examples on the website.
H3 is based on a dodecahedron it is it the reason the cell areas range so much, the same is true of S2 - but this is based on a cube.
I find tracking movies and series I have watched with my partner an impossible task. Spreadsheets are too fiddly for my partner, and I want to look up what is next on my phone so I have turned to Airtable and n8n for automation.
input a relevant url, it will decide if it IMDB or Youtube or a list.
using an llm, it will attempt to extract the movies or series from the list and find the relevant IMDB link.
Then I have a masonry view of movies & series I have and have not watched, sortable by tags that I can rate and add notes to.
I've always been into MUDs since the mid-90s and every now and then I get this idea to write one from scratch (again) and I get pretty far and then I lose interest.
The new one is browser based.
The mud engine runs in a web worker and takes advantage of some of the modern web tricks to do stuff. For instance, data files (think: area files that don't change often) can be stored remotely and then cached with a service worker. This allows the MUD to run offline. But that's only fun if you're playing solo.
IO between the UI and worker is handled by message passing.
Multiplayer is handled by the MUD opening an outbound connection (probably websocket) to a connection collector host. Other players would then connect to that host and have their IO routed appropriately. The host can even be smarter: it could be a specialized Discord client, allowing users to play from there. Firebase may also be involved. I don't know.
The important bit is that this is still basically message passing, so the engine won't need to know the difference between the local user and a remote user.
The MUD database would be an IndexedDB. Probably. I haven't thought as much about that yet.
I am sure all of this is theoretically possible, at least.
YES! Another MUD programmer! I started writing one in Meteor about eleven years ago. I don't even know if Meteor's still a thing anymore... I've had a few projects in Rust that were mixtures of roguelike and MUD models, conceptually. I usually got aggravated with the models I created, though.
I really like your multiplayer idea. That sounds really clean and flexible.
Working on a database compatibility tool. So your app works on SQL Server 2022 on-prem, but does it work on Azure SQL DB, AWS RDS, GCP CloudSQL, etc?
These cloud flavours have a compatible SQL dialect, but it's often details like missing features (CDC and Auditing on RDS are good examples) or differences in system objects that make it difficult to support your app on these platforms.
I capture all sql statements, run them through multiple SQL parsers to find all the system objects your app is using (tables, functions, stored procedures, etc). I then check them all against a catalog I have built of all system objects for every version of SQL Server on every platform.
I then give a report to see which platforms your app will work on, which ones it wont work on and which system objects are the problem.
Other database engines will be added once I get it working end to end (almost there).
I just put live a daily logic puzzle, Clues by Sam. I've been working on it for a while now, mainly on the level generator. It was tricky to generate levels that are solvable using logic (no guessing needed), and also fun to solve (no crazy long deduction chains, but also not just obvious things). I'm sure the implementation still has some quirks on some devices, so would love to hear if you encounter issues!
I really enjoy this! I like Murdle, too. I was very interested in a sort of quest generation system that would use similar concepts to generate RPG quests, basically constraint solving I suppose.
Thank you!
This was definitely inspired by Murdle, so glad to hear it's finding the right audience. And yes, constraint solving is definitely at the heart of the generator. And you mentioning using it for RPG quests sets my mind racing...
Highly enjoyable (after I finally read the definitions of "neighbor" and "to the right/left")! Did you write a program that can automatically generate these?? I'll definitely try this again. Note, the emoji graphic in "share" might be buggy? I'm seeing one green checkmark, one green square, and four red squares..
Thank you so much for trying out the game and taking the time to write the feedback!
I did! That was the main workload of this project, and is still ongoing. I have ideas for improvements, and I also have to fix some sentences manually sometimes. But it's getting there.
The sharing shows a kind of "health bar". Every time you make an illogical guess, it reduces one. Running out of "health" doesn't prevent you from completing the puzzle, but it does show up in your share. Based on this, you made 4 "illogical" guesses. If you didn't, then there's a bug. But feels like I should anyways clarify this, if it wasn't clear to you. Thanks again!
This is great, but the need for a long glossary of terms is a sign that you might want to keep tuning language/word-choice.
As you've seen in replies here already, many term choices you've made have enough variety in how they're conventionally used that people incorrectly assume they know what it means only to see the "nope!" popup when they try to apply it. That frustration is going to spoil first impressions of what actually seems to be a really great puzzle system, which is a shame. The more you can reduce that experience, the less likely you'll be to prematurely burn off players.
A good measure for getting it right would be that you don't even need a glossary at all, or that you can get it so condensed that you can make it more prominent without becoming distracting.
Alternately, you could maybe use symbols instead of words to represent your rules, as more players would intuit that they should learn the symbols before making (wrong) assumptions.
This is great feedback, and I think you're spot on. It's been really challenging to find wording that is brief enough, but also specific enough. I hope it's something I can improve in the future as I keep exploring new ways of giving hints. The idea of using symbols is interesting, hadn't considered that!
frustrating. i eventually just clicked every single one, and keep getting the "This choice can't be made based on pure logic" message. maybe i'm just dumb...
You might be misinterpreting what "neighbor" means or what "to the left" means. There is always at least one choice that can be made logically. If the logical choice is, say, that Jess is innocent, and you say Jess is a criminal, the game won't let you do that choice. Maybe that's what happened to you?
I am working on an app for rhythm training for dancing.
The first step is beat detection in music - here is my code for generating videos with beat counting: https://github.com/zby/beat_counter (vibe coding warning). Beat detection seems to work OK, downbeats are a bit more tricky and I have found not good solutions for further structuring of music (for dancing they usually count to 8 - that is two 4 beat measures - or 6 - two 3 beat measures for Waltz for example, I am not sure about 2/2 measures and other). Seeing all the LLMs generating music I thought there should also be LLMs interpreting music - but so far I have found no such model the available algos seem to be from a previous decade.
My current plan is to test the counting with people with good rhythm sense and once I find a good algo for beat detection I'll proceed with writing the app.
Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol).
I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, etc.).
After researching how the Toyota/Lexus infotainment systems work I found they are highly modular, and actually quite easy to produce custom modules for. The proprietary AVC-LAN protocol is well-understood, and actually makes it really easy to integrate with. The display are just NTSC composite, and touch events (in fact, all button presses, including steering wheel media controls) are emitted on the AVC-LAN bus.
An simple board with some interfacing logic, a DAC and an RPi nano should be all I need to allow good Bluetooth audio integration, and lossless audio via wired USB, both controllable from the steering wheel.
You could do all sorts of fun things with the display (such as displaying vehicle status from ODB, lap timer, G-force meter etc.). If I use a RPi compute module then running Android Auto should be quite feasible.
It's just a hobby project though, I'll probably open-source everything. Not planning on commercializing it.
Version 2 is being built around a CM4 IO board and will include my AVCLAN implementation, DAC, GPS and is intended to run AOSP Android. The board is fully designed already and I'm working on the custom Android build now.
Godspeed. I find it frustrating these systems don't follow some sort of international standard, still. I can't justify replacing the system in my 2016 Highlander just to get Android auto, but the Bluetooth system handles non-phone calls poorly and the album art database hasn't been updated for basically the entire life of the vehicle. I don't like having to rely on the manufacturer nor Google/Apple for connectivity basics.
Building an app that extracts key information from PDFs + highlights citations.
You provide a PDF and a JSON schema defining what to extract, and it returns the extracted values, the citations and their precise locations in the document.
This is especially valuable in workflows where verification of LLM extracted information is critical (e.g. legal and finance).
It can handle complex layouts like multiple columns, tables and also scanned documents.
Planning to offer this both as an API and a self-hosted option for organizations with strict data privacy requirements.
I've been working on some structured OCR tools recently (in the context of reading resume pdfs and allowing much more useful search filters over them than our ATS system allows) and I've found Gemini with structured outputs capable of doing a fantastic job. I'm curious, do you have any rough pointers for how to do this self-hosted?
So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources.
The DB contains different types of proxies:
- Residential
- ISP
- Data center
I don't include mobile proxies since they're heavily shared, so knowing that an IP address was used as a proxy at some point is basically useless.
Regarding your remark, indeed, there are several shared residential IPs, including IPs of legitimate users who may have a shady app that routes traffic through their device. That's why I don't recommend blocking using IP addresses as is. It's supposed to be more of a datapoint/signal to enrich your anti-fraud/anti-bot system.
However, regarding the block list, I analyze the IPs on bigger time frames, the percentage of IPs in the range that were used as proxies, and generate a confidence score to indicate whether or not it is safe to block.
I’m working on a scraping project at the moment so looking at this too but from the other end. Super low volume though so pretty tame - emphasis on success rate more than throughput
I bought a 4G dongle for use as last resort if nothing else gets through. And also investigating ipv6
Using a 4G dongle makes it easier to hide in the crowd indeed. Since your traffic will go through heavily shared mobile IPs, probably with thousands of users behind them, anti-bot vendors won't/shouldn't block per IP, but per fingerprint/session cookie instead.
AI has taken over the hype in sales and go-to-market strategies. But for independents, solopreneurs, professionals, and many founders or CEOs, relationships and partnerships are still central.
I think sales will bifurcate: either fully automated self-sale, or fully relationship based. All of the major CRMs (customer relationship management) software are going all in on AI and sales automation.
I think relationship sales is going to see an increase in comparative advantage. I've always been a relationship seller but the current crop of CRMs are not designed for me. So I've built https://humancrm.io/ to scratch my own itch.
I'm working on a human-like AI opponent for VR table tennis. It's something I really want myself, love playing table tennis in VR, but with online play you get the latency issues, people that have adopted a playing style which basically hacks the game physics or other aspects, or people who are just plain rude. Playing against the AI is much nicer, but it's not varied or realistic enough such that when you actually play against real people you are ill prepared.
Last month, I started playing around with code sandboxes and how LLMs might interface with them and wrote a little blog post about it [1]. I then took the code and vibe coded my way to a multi-tenant (untested!) sandboxing server that lets you run arbitrary Docker containers and provides a simple HTTP interface and UI. A cute, novel idea is that you can fork containers easily, as seen in the video in my repo:
It may not be useful, but it's been fun, and I've honed my gut-level experience in Docker, Podman, Linux namespaces, Checkpoint/Restore, CRIU, and more. The ultimate goal is to hand each AI agent iteration a sandbox of its own (forked from the previous iteration), and have it build apps in private sandboxes. You'll be able to view intermediate progress as the app is being built (or failed rabbit holes), since each sandbox gets a unique URL automatically. Like, imagine if each commit of your git repo had its own URL to preview the app!
7 months ago, I was looking for a job and got frustrated with the current resume builders, so decided to build one exactly how I wanted a resume builder to be.
Really neat app! A button that says "instantly" and actually does the thing instantly already makes this better than every alternative! ;)
Maybe just an idea I think would be worth charging for to offset costs on yourself: if you could get a few accounts on different recruiting software packs (BambooHR, smartrecruiters, etc) and then let users test their resume with different recruiting software's AI filtering tools, that could help a ton of people. You'd have to make a lot of different job descriptions/postings in each one, but you could probably craft them all generically enough to fit most careers.
Once that's going, maybe a pay-per-use fee to test your resume that gives the paying user a couple unique recruiting links to a few job postings, and then use playwright or something to capture screenshots of their profile in the backend(s).
I like your idea, but its hard to implement due to privacy concerns and could violate the ToS of these platforms (for sharing the account).
But I do have a feature in mind to do something similar. My plan is to always keep it free, with any feature, but I have to think of monetisation. Right now, it would be charging employers/job boards instead of job seekers. I've been there, the job search is stressful enough to add financial burdens.
Would like to see more written down on how the résumé-building part works.
Would love to see something that can start from a pre-existing CV and help refine. (My current CV is my own record of projects I have undertaken, so it has a lot of detail and runs into approx. 10 pages.)
You can upload your current CV, and it will parse it to fill out the form for you. You can then amend or improve it, choose a design, and export it as a high-quality PDF.
I will try to write about it. I faced some challenges related to exporting as a high-quality text PDF, including multilingual support and ensuring JS messages are all translated, among others.
My home-grown daily word game Omiword[1] (previously discussed on HN[2]) is nearing completion. Just a few last features and bug fixes to go, including a hint feature, access to archives, and a sharing feature.
Working on writing a series of blog posts on interaction nets. The first one is up already an is an introduction to the topic [0]. I feel like the topic is very accessible but the ideas are spread out across discord channels, papers, twitter, and GitHub repos. Hoping to centralize it a bit.
In short, at the core of Tangled is what we call “knots”; they’re lightweight, headless servers that serve up your git repository, and the contents viewed and collaborated upon via the “app view” at tangled.sh. All social data (issues, comments, PRs, other repo metadata) is stored “on-proto”—in your AT Protocol PDS.
Work wise I'm building a discrete event simulation with pysim. I manage the autonomous vehicles program and underground control center for the subarctic mine I work at, and we've desperately needed some means to evaluate efficacy of designs and forecast productivity. Using it to model scoop-truck movement and loading operations, and it's working very well. It's been a joy.
I've been taking advantage of the enormous context window of Gemini 2.5 pro to have it make upgrades, fix issues, and just generally doing all the legwork.
Personally I'm having fun learning some web design and three.js as I try to debug the very tricky issues with my new personal website loufe.ca using AI is fantastic but you need to micromanage when things get complicated, I find.
I'm working on an escape room! Initially I was working on a software/hardware bundle that I was planning to market to other escape rooms but I think that is the wrong approach. So I am going to build a bunch of modular stuff in my garage and eventually start my own, its been an awesome project so far! I want a more dynamic and action oriented experience so it might not really be an escape room anymore but I don't know what to call it yet.
Escape rooms are honestly... almost always a let down but the concept has a lot of potential and there are some really neat ones that standout like this local one where you pilot an airship https://www.portlandescaperooms.com/steampunk-airship
Once I build the best escape room on the planet, I can consider selling the tools.
Some sort of escape room backbone software that links together all of the hardware according to a script is such a neat idea. It would be so cool to have something like Twine [0] to build out the story graphically, where input/output is via cues to staff/hardware rather than just text on screen. An old boss of mine used to run home-haunts for halloween. (a walk-through haunted house experience scaffolded-up in his yard) I helped him a few times, and I was always amazed by how big of a community there was. There were at least 5-6 people doing a haunt next week and would come help out at his, then he would help at their haunt the next week. My boss was even making a magazine for the community for a while. Something for those folks doing quick popup theatrical events/escape rooms that could handle some "duct tape engineering" would totally have an interested market, and if it was open source you'd get great patches.
BUT I also get what you mean, have find out what works first. Do you have a blog for your escape room progress? That sounds like such a cool thing to follow you making!
Have you ever visited a Boda Borg? They’re not quite escape rooms; generally, the experiences are fast-paced. Some are puzzles; some physical challenges; some, an interesting mix. Lots of computer automation to make it all work.

https://marketingagents.net - Marketing Automation for Founders who Suck at Marketing. Open Source and Self Hostable
Building this for myself mainly, but hoping others might find it useful. Still very early and building out the bear essentials, but then the hope is to keep reading marketing books and use that to improve the platform.
Right now I’m focused on story development and integrating it with the daily-puzzle system I built last time I was between jobs.
This is a years-long slow-burn side project.
My career moved away from the frontend long ago—this is my first React app, with a Django backend running on AWS Lightsail.
A open-source Looker/Data Studio alternative, supporting Bigquery/Snowflake/DuckDB. Has a custom SQL dialect with embedded semantic layer to make reusable and interactive visuals easier. Can be self-hosted, but a public version is available. Still very WIP!
I’ve been working on a side project called jobswithgpt — after months of building and refining, the first version is finally live: https://jobswithgpt.com
The idea is simple: a job search site that actually works for job seekers. It focuses on listings posted directly by companies (no spam, no middlemen, no bloated sponsored posts drowning out real opportunities). It uses AI to surface better matches, recommend jobs intelligently, and pull out the most important info from job listings automatically. You can also bookmark jobs you’re interested in and track them easily — no signup needed unless you want personalized suggestions.
It’s still early, and we’re improving it constantly. Would love for you to check it out, try a search, and let me know what you think — good, bad, rough — all feedback helps. Thanks a lot for the early support!
I'm continuously building and improving https://lectronz.com/, a marketplace for electronic enthusiasts and professionals that focuses on the open-hardware and DIY electronics communities.
We recently introduced "Threshold Pre-Orders," a pre-order mechanism that lets hardware creators gauge the market before committing to production/PCBA.
We have successfully tested this on four low-volume products already. See https://lectronz.com/u/lectronz/articles/introducing-thresho...

I am working on an administrative app for small shops. It has inventory, invoices, quotes, returns, purchase orders, payables, receivables, finances, etc. It's almost ready for v1, just finishing the final touches to start onboarding first users
A very misguided project that started with me trying to run Linux on a newly acquired 386DX-40 and has led to me building my own Linux distribution for said purpose
As a follow up to my relatively successful series in x86 Assembly of last year[1], I started making an OS that fits in a bootloader.
I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes.
It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor. It's a lot of fun!

The book is written in the Choose Your Own Adventure style. Readers get to join the protagonist Daphne on a fun, week-long adventure launching her own mini-businesses. Readers help her make smart decisions, solve fun challenges, and learn about money and problem-solving in the process.
The book has been a fun endeavor in both writing the manuscript and code! On the latter, I wrote an exporter for Twinery to Org Mode and an Emacs Org export backend to do the reverse.
- Snapshot (https://apps.shopify.com/snapshot): AI generated product photos for Shopify. Previously used Flux and Stable Diffusion but always had quality problems. Was very tricky ensuring text remained the same and the product fit into the generated background. Just integrated the new OpenAI image generation model and results are much better however their masking feature doesn't work properly so need to wait for them to fix that before I can offer the same feature of keeping text/fine details the same
- Lurk (https://apps.shopify.com/lurk): New one I just launched - allows Shopify merchants to track the prices of competitors and adjust their own in response with dynamic pricing rules. It's cool because you just have to paste a URL and it uses AI to figure out the price. Again, there's a surprising amount of things you need to figure out to make this work reliably at scale (e.g. popups, ambiguous HTML, location-based pricing, etc.)
Main work: tokenization of real-world assets, but on the side I’m building two projects as a solo dev:
- XRoll.io — a fully on-chain gaming framework on the XRP Ledger, inspired by SatoshiDice but built for compliance. Commit-reveal fairness (HMAC_SHA256(secret, bet_txn_hash)), full transparency on-chain. Integrated KYC, AML, self-limits at the protocol level. Frontend is optional; ledger is the source of truth.
- Nexula — an evolutionary image generation system. Embeddings extracted with CLIP, clustered via HDBSCAN, visualized with UMAP. User behavior (time spent) drives fitness scores; top samples recombine through weighted interpolation to generate new images. Built on Django backend, session-based personalization without login.
Looking for like-minded people interested in exploring both the technical and business sides of these systems.
I'm kind of contemplating the same thing - not leaving the corporate world, because I have too many bills and debts for that - but getting a PhD in something, maybe math or CS. I don't know that anyone really does that in their forties, though...
Am an engineer (EE + CS) with 25 years of work experience, with a passion for Physics. Am widely known in my circles as a scientist/physicist, however, I do not actually know much. Learned some Lagrangian and Hamiltonian classical physics recently.
I personally do not mind going for even an undergrad in Physics if that would be a better fit for me to learn. :-)
That's awesome. I often dream of returning to a formal learning environment, I didn't appreciate how special dedicated (extended) time for learning was when I was in school.
I'm working on running sequences of heap operations (insert and delete-min) in linear time instead of O(n log n) total time. It's a silly little project in theoretical computer science I have.
Crucially, to make this bound work, you only learn the final state of the heap, not which element got deleted when.
Working on a site to help people find stained glass windows to visit in their towns/cities. No exciting tech (vanilla HTML/CSS/JS) and lots of data entry, but making some decent progress!
TUI browser for the Modern Web. Runs JavaScript, works everywhere, but only shows text. Quietude, noise cancellation for content. Sneak peak: https://youtu.be/rmykR_OLYhg
I also just today made a fun way to fully host a front end and SQLite back-end on GitHub for free using Pages + Actions, you can try it right now: https://do-say-go.github.io/fully-hosted/
Silly lisp-inspired language, but it turned into something different as I started asking myself more and more questions, and now it's more of a model for computation that tries to think about computers as different from looms (aka harward architecture).
One where self-modification is the norm, where there is no stack unless you make one, and where there's no difference between a program extending itself or the programmer doing it (unlike LISP macros, my language, and model, does not have a distinction, there's no macros).
I'm not doing this because I'm convinced it's a great idea, or because it's going to revolutionize computing, or because it will be a good language, model or beneficial in any particular way, I'm doing it because I think it's fun, neat and interesting to think about (and talk about).
I'm working on an unified MCP server that can search and use a large number of tools. The current way of using MCP server (adding each MCP server directly) simply doesn't scale.
If your AI agent needs to use 100 tools, you need to manually configure a lot of MCP servers. And when you feed those tools to the LLM, it may get confused and tool calling accuracy starts to drop.
This is why I'm building a unified MCP server with just two meta tools:
- Search Available tools
- Execute a tool
When I want to send an email, I ask LLM to use the Search Meta tool to search for Gmail related tools in the backend, then the meta tool returns the description of relevant tools. The LLM then uses the Execute meta tool to actually use the gmail tool returned.

I used "Claude Code" to create a local-only webapp for tracking symptoms of my chronic sinusitis, which seems to be tricky for the doctors to figure out, over time, using the "Sino-Nasal Outcome Test" (SNOT-22) questionnaire. Trying to correlate environmental and medical factors and interventions with raises or decreases in my symptoms.
I'm a member of the JSON Schema Technical Steering Committee, and been making a living consulting with companies making use of JSON Schema at large. Think data domains in the fintech industry, big OpenAPI specs, API Governance programs, etc. The tooling to support all of these use cases was terrible (non-compliant, half-baked, lack of advanced features, etc), and I've been trying to fix that. Some highlights include:
- An open-source JSON Schema CLI (https://github.com/sourcemeta/jsonschema) with lots of features for managing large schema ontologies (like a schema test runner, linter, etc)
- Blaze (https://github.com/sourcemeta/blaze), a high-performance JSON Schema C++ compiler/validator, proven to be in average at least 10x faster than others while retaining a 100% compliance score. For API Gateways and some high-throughput financial use cases
Right now I'm trying to consolidate a lot of the things I built into a "JSON Schema Registry" self-hosted micro-service that you can just provision your schemas to (from a git repo) and it will do all of the heavy lifting for you, including rich API access to do a lot of schema related operations. Still in alpha (and largely undocumented!), but working hard to transition some of the custom projects I did for various orgs to use this micro-service long term.
As a schema and open-source nerd, I'm working on my dream job :)
That's really neat. I've been doing some JSON schema work on our products recently, especially trying to take a schema and generate info compliant with the schema for e.g. testing accounts with clean data on non-production environments, etc. I feel like the area's underdeveloped.
It is an interesting discovery journey on extracting relevant information from both code and documentation with a sufficient density to stay within the context window and extracting efficient criteria from arbitrarily phrased questions.
A few released apps for now that are iOS/macOS, with some exciting more things in the pipeline.
If you’re a photographer who has frustrations with current mainstream photography software (whether capture/edit/publishing), I’d also love to hear from you - you can find me as Héliographe on (mastodon,bluesky,threads,x) or just email me at contact@heliographe.net :)
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'm working on a pure js webgl image editor with effects, filters, crop & perspective correction, ... oh and it's opensource as unfortunately most comparable solutions are closed sources
I wrote this tool to make instrumenting language servers very easy. MCP (both protocol and architecture) seems heavily inspired by LSP which made me curious about what it would take to support it through my telemetry-capturing proxy.
Haven't thought too deeply about how useful an MCP proxy can be but I see it as potentially a general platform for monitoring or debugging MCP servers or clients.
I'm working on a new open source CAD program for 3d printing based on Signed Distance Functions.
Benefits of SDFs over the standard Boundary Representation (used in Freecad and similar) are that you can do "pattern" operations with domain repetition, which means making N copies of a feature is O(1), vs O(N^2), you can deform objects with domain deformation, which means if you have a closed-form representation of how you want to deform space you can basically directly apply that to your object, procedural surface texturing is easy, CSG operations are easy.
The big drawback is that it is hard to provide any workflow based around "selecting" faces, edges, or vertices, because you don't naturally have any representation for these things, they are emergent from the model's SDF.
I am solving the "selecting faces" problem by having the SDF propagate surface ids as well as distances. So the result of the evaluation is not just the distance to the nearest point on the surface, but the id of the specific surface that is nearest.
My next big frontier is reliably providing fillets and chamfers between arbitrary surfaces. I have a handful of partial solutions but nothing complete yet.
The most promising idea is one that o3 came up with called "masked clones", the idea is roughly to make a clone of the 2 surfaces you want to blend, mask them by intersecting with an object that is like a "pipe" along the intersection of the 2 surfaces, apply the blend within the pipe, and then add this "blend pipe" as another child of the lowest common ancestor of the 2 blended surfaces.
And after that I need to work on more standard CAD stuff like constraint solving in the 2d sketch editor.
This is super neat, cool that you have an online demo as well.
I wonder if there are any ideas on how to make this a OpenSCAD-style editor instead of interactive? I like the text-based style for simple regular shapes, but they tend to end up too simple and regular. Maybe tools like filleting edges SDF-style is a game changer?
A midi sequencer, which does or is supposed to do what you expect.
In the process of adding stuff like euclydian sequences, and trying to figure out
how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory
behind it.
It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.
That's a cool project, but learning music via music theory is a bit like trying to learn English via grammar theory. It's backwards, and out of the hundreds of musicians I've met, I've never met one that walked that path.
Strong recommendation: Hire a teacher. Even with experience playing four instruments, and when I decided to learn another, I still hired a teacher.
One of my goals for this years was to get a jazz teacher, specifically for guitar.
A layoff killed that goal for the foreseeable future.
Theory has helped me practice like I think you're supposed to. More structured,
more analysis. It also tickles the same part of the brain the certain comp sci topics do.
I think it came from wanting to learn how to improv, and then wanting to make my own songs. So I make a few tracks a week, of different genres, depending on what I'm interested in at the time. I've seen improvement, and I take notes about what I learned/what works.
Letterboxd for video-games! Don't know if it's novel enough but it's given me the chance to get into front-end design and think harder about database design.
Still working on Connet[1] and the associated Connet.dev[2], which is a p2p reverse proxy with NAT traversal (and hosted version of it). Currently, adding support for defining multiple points of ingress, next will be adding support for PCP port forwarding.
A social advocacy platform for small and medium sized B2B businesses.
LinkedIn is more or less the only social platform for B2B social selling and smaller firms could benefit from their posts getting a bit more augmented and coordinated engagement. So we’re building a solution for a marketing manager to request advocates (employees, partners, others) to engage or reshare (tweaked in their own voice if they want) their content.
Not world altering but shockingly underserved market. With few players who raised money and therefore have to price expensively, whereas as a bootstrapped side-hustle we can offer it in a flat-fee way that doesn’t “penalize” growth by charging per-user or for inactive users.
I'm teaching myself category theory, I'll kick back off a local trail, keep notes on the birds I see and read and do the problems in my notebooks. I've got Basic Category Theory by Leinster, and How to Read and Do Proofs by Solow as my references, notebook, pen and a pair of Nikon binoculars.
Can I ask what prerequisite mathematics you would need to know before reading those? I'm really interested in that topic and better understanding functional programming.
If you wish to approach Category Theory from the viewpoint of a programmer, not a mathematician, I suggest Bartosz Milewski's book Category Theory for Programmers. For this, all you need is some previous programming experience. He uses C++ and Haskell iirc but as long as you can read snippets of code, you'll be fine.
I am suggesting this since you said you want to better understand functional programming. Category Theory, as mathematicians look at it, is an extremely abstract field. If you want to do pure math related stuff in Category Theory, and only then, I would say important prereqs are Abstract Algebra and Topology. I believe the motivation for Category theory lies in Algebraic Geometry and Algebraic Topology, but you definitely don't need to be an expert on these to learn it.
https://undetectag.com I developed a device that turns an Airtag on and off at specific intervals.
Current Airtags are detectable right away and cannot be used to track stolen property.
That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location.
It’s not foolproof, as the timing has to be right, but still useful.
Due to its timing, the device is not suitable for stalking someone. Additionally, if you place it in someone's handbag, for instance, once the AirTag comes back online and the person starts moving, they will be alerted that the AirTag is tracking them.
I wanted to know what my kids were doing on the computer: homework or watching youtube shorts, so I built https://screenspy.app to monitor them. Now I’m working on turning it into a product.
I've been using something like Google Family Link, which works fine, except that it ties in to Google Family, along with YouTube, Play Store, Google One. I'd have to kick my sister out of the group to monitor another daughter and it means there's a limit on the number of children you have; such terrible design.
I do want to give them a little privacy and it gets to the appropriate level. Like restricting some apps at certain times, access to chrome but not xhamster. Locking it for certain periods of time and having them request more screen time past 4 hrs/day. Locking the phone whenever they've barricaded themselves in the room the whole morning.
I don't necessarily mind that they're watching YT or TikTok and such. I just want to kick them out of the doom scrolling cycle every now and then.
I really like this idea of silent monitoring. Monitoring and talking about bad things seen weeks/months later. Because while I can block everything I want at home… there are other kids with free Internet access where everything is available and then I have no idea what’s happening.
Learning Rust by building a simple database using it.
I’ve done my share of programming languages (PHP, C++, Python, Ruby, Haskell) and for the last 10 years I’ve been working in OCaml (which I love so much) but Rust would be a nice addition IMO.
And I never implemented LSM style database before! So that’s fun.
I realized after trying multiple tools like Supabase and Firebase, I really need to program my own solution. I don't need a bunch of *Enterprise* level features. I just need to read the card data from a database, and process the games with some simple server side code.
I hope to have the server, along with a basic front end done by this summer. Then it'll be released under a permissible license. Probably MIT.
I want a community of different front ends compatible with the same server. I suspect a straight up cli client without a bunch of effects might be popular with some of y'all.
If you want to code a frontend in Unreal, the server doesn't care. The game remains the same.
Of course your free to fork it privately, build a commerical product, etc.
Working on a web app builder that generates code via AI, much like hundreds of other tools out there. The differentiator is that the tool automatically sets up a Postgres DB (using Neon) for you. So, it's a lot easier to get started and it can handle large complex apps that require auth and database, but it can also build simple websites. The stack is next.js and code is easy to export and view.
Primarily uses Claude Sonnet 3.7 and Gemini Pro 2.5. But you can choose other models too.
My primary goal is to make a game that's fun. Secondary goal is to make you experience why an AI might do things you don't expect. Specifically, to further instrumental goals like collecting resources, refusing being turned off, things of that nature.
There are two endings currently but I'm working on adding some more.
Still supporting https://monkeys.zip - my pet art project where users simulate thousands of monkeys on typewriters for silly rewards. After which, moving on to a music creation app.
Trying to understand the possibility and feasibility of LLM on Indian vedas and ancient hindu mythology. I am thinking like there is a input box where user will enter his problem,/query and get resolved with the help of Vedas, puran and old hindu religious books.
I have revived my work on Go Micro (https://github.com/micro/go-micro) and rewritten the v5 cli/api from scratch (https://github.com/micro/micro). As a VC funded company there was a lot of confusion around the tools we were building and we veered off in a direction that alienated the community. With the company dead, funding gone, etc there's an opportunity to rebuild value around the Go Micro framework.
The second thing I'm working on is the Reminder (https://reminder.dev && https://github.com/asim/reminder). As a muslim I feel like it's my duty to spread the word of Islam and as an engineer I feel like an appropriate way to do that is build an app and API for the Quran, names of Allah and hadith. It's a slow patient building of something as opposed to expecting anything from it.
In terms of new ideas, maybe not new but less screen time, less phones, more nature.
After working on it for a while, I noticed there’s a stigma around using CORS proxies, often associated with fetching undocumented APIs.
While that’s sometimes true, I’m hoping to change that perception, to show that they can also be used for accessing real APIs. It just requires the proxy to correctly handle credentials and secrets.
The idea is to open up more possibilities for building static-first apps without worrying about CORS.
Working on: Pantry Recipes – AI meal generation based on what’s in your kitchen
Over the past few weekends, I’ve been building Pantry Recipes – a mobile app that lets you quickly generate recipe ideas based on the ingredients you already have at home.
The idea is simple:
- Save or quickly select ingredients you have on hand
- Tap Generate Recipes and get ideas instantly
- You can also describe what you want to make free-form (e.g., "cheese omelette") and the app will generate a recipe for you.
Cool idea! I’m a big fan of AnyList so this was intriguing.
I think it could be useful to have a “recently generated” section in the Recipes tab that lets you find things you might have forgotten to save. Substitutions could also be a useful feature. For example, if I can’t find Mexican oregano, what else can I use?
Since you are using AI, what are the chances of your app suggesting existing recipes vs "inventing" new recipes.
Also, there can be set of ingredients that should not be mixed together or be cooked in certain way. Are these cases considered when generating recipes ?
Robot walking. But really, a programming language and tools to make it easy to solve hard nonlinear control problems like walking. There are videos & source code for 2-legged walking robots (in simulation) at https://throbol.com/post/how-to-walk, and videos & source code for 4-legged walking robots (on real hardware) at https://throbol.com/
(1) Business process modeling tool where processes are data and not graphs. I am doing it according to the USM method. USM is kind of "open source" service management method, although it works on different level than other frameworks and standards, and is compatible with all of them.
This makes it possible to create a kind of requirement "programming language" where the requirements can be evaluated. With this language it becomes possible to create cross-references from various compliance standards/frameworks, like ISO27K, to USM, and automatically evaluate the compliance.
(2) Dance event calendar in Finland, running in production for over a year. 1-2M page views/month. Django app, but I am now implementing a copy of the unauthenticated user views to S3 bucket and delivering it through Cloudflare.
(3) Django app to handle all the data related to custody trial. Emails, SMS, notes, official records, voice memos, etc. can be attached to a timeline, and tagge and searchable. It has command line interface for adding data, in addition to UI, so I can quickly add notes and attach files.
I'm working on an open-source Pivotal Tracker. I just started a week ago but if anyone is interested in following please checkout the repo: https://github.com/bendangelo/Iterator
I'll have a working project in about a month. But for now it's just a readme.
Working on Uncloud [1] — open source tool for self-hosting containerised apps across multiple machines. You can combine cloud VMs and on-premises to create hybrid compute environments, e.g. for cost optimisation or data privacy.
While Kubernetes offers power at the cost of complexity, Uncloud focuses on simplicity for common deployment workflows.
Progress from this month:
- Enhanced Docker Compose support: You can now deploy your entire stack from standard Docker Compose files. This includes volumes, environment variables, resource limits, scaling and logging configuration.
- Volume management: Create and manage Docker volumes across your cluster with automatic scheduling based on volume location.
- Context management: CLI command to quickly switch between multiple clusters, e.g. homelab and production one
I'm particularly excited about the volume management system as it provides the cluster semantics to the good old Docker volumes. It uses a constraint-based scheduler that ensures services sharing volumes are properly co-located.
If you're seeking something between "just Docker" and full Kubernetes for deploying applications on your own infrastructure, I'd love to get your feedback on Uncloud.
i am building a little iMessage app called Whenish.
this was spurred from group texts with friends planning a vacation or outing. we would just throw a bunch of dates that would get lost in the mix and people would forget who was open on what dates. Whenish just allows user to select dates they are free and then it will show what is the best date that works for everyone.
i have a testflight right now and if anyone wants to give it a go please do! i would love feedback :)
A Markdown-first CMS and website builder for blogs, newsletters and documentation websites.
I've been blogging since more than 10 years, and the only thing that made it possible is Markdown. That's why I've decided to build a complete publishing platform to replace the complex and fragile setups of bloggers and startups. Do you really need a CI/CD pipeline, static site builder, hosting, CDN and analytics just for a website? :/
The platform is currently 100% operational and I'm now working to Open Source it.
The best thing? You can publish directly from the CLI:
I'm still developing podcast websites with transcripts[^0] while maintaining a part-time job.
This thread made me realize I've made no progress in acquiring new clients since posting about this 6 months ago. However, my part-time job ends in May, which will allow me to focus exclusively on Fanfare. It's somewhat intimidating, but I'm also looking forward to it; the prospect of resolving this uncertain situation (either through success or failure) feels liberating.
Working on a series of interviews with gamers about how the hobby is part of their lives, called Unmuted [1]. It's been awesome to interview people from different backgrounds and see how gaming has influenced them.
It's the first original piece of content for a newsletter of curated gaming content that I've been running for more than five years now, called The Gaming Pub [2].
I spent the weekend working on the Ansible automation needed to deploy Tomcat and Roller Weblogger for my new personal website/blog[1]. Once the loose ends are tied up with this, I plan to deactivate my Facebook account and mainly focus on the personal site + Fediverse sites for sharing stuff. This is both to be consistent with my principles, which say to disfavor closed-source / walled-garden sites like Facebook, and because it should free up some time I waste when I allow myself to get pulled into political discussions on FB. It'll probably be better for my mental health as well.
I have small solo project that I am slowly expanding on. It started as an old-fashioned text sentiment analysis more for my amusement more than anything else ( no real insights were gleamed so original version was used as a foundation for what came next ). I don't think I will ever put it out there publicly, but it keeps me occupied when I need a distraction.
A little free library style box, but not free and not a library (https://thingio.dev)
I've got an LTE module connected to a solenoid lock. The module listens for a "checkout complete" callback from a Stripe payment link which will unlock the solenoid. There's also some weight sensing involved to track the current product inventory inside the cabinet.
I built this for a family friend who does a lot of wellness outreach around combating food deserts by introducing small scale farming to local schools.
As a result of their community bee hives, they have a bunch of excess honey. So, I thought I’d build them this little honey vending cabinet for their neighborhood.
I've expanded the service a bit to be more product agnostic, maybe someone else can find a use for it.
I've been working on https://asterai.io -- a platform for developing, running and managing AI agents.
It lets you create multiple agents, configure them via the web console (such as LLM parameters and system prompts) and manage their plugins and functionality.
The system is fully plugin-based, where each plugin is a WASM program that exposes functions/tools that the agent can call, and can also hook into the query lifecycle. Because plugins are WASM, they can be written in various languages such as Rust, Go, TypeScript etc. Plugins can also act as libraries, which is possible because of WebAssembly Components (a great piece of software!) -- so you can dynamically call functions from other plugins within your agent, and you get type support for your chosen language too (with codegen via WASM Components tooling).
More recently, I've been working on an SSH server for agents. The idea is that you can add public keys to your custom agent and then SSH into it to talk to it easily from terminal.
If this sounds interesting, feel free to join our Discord! The project is still new and feedback is highly appreciated. http://asterai.io/discord
That's a good question. Currently, there is one way to do it. The client querying the agent receives JSON-encoded values that are returned from plugin function calls made by the agent. These values are received alongside the agent token response stream (via SSE). So plugins can essentially emit events that the client can forward to the UI application, such as to click a button etc. The limitation with this is that there is no built-in way to send a success/error status back, it's one way only. It works well for actions that are infallible such as simple UI actions.
The client here would also need a way to interact with the target program of course, e.g. from a JavaScript browser you can click buttons and manipulate the DOM, or from a VSCode Plugin you can interact with the editor etc.
It's definitely something that can be improved though! I've been thinking about some type of MCP interoperability that could maybe assist with this.
so I'm working on side project to make managing and exploring your music library easier.
The idea is you can set a few filters (like bpm, key, decade, genre) and then swipe through random songs, accept or reject them for inspiration or playlists. Kinda like Tinder but for digging through your own tracks.
It also tracks what's trending on TikTok/YouTube/SoundCloud weekly, so you can find stuff that’s blowing up, filterable by region. Plus it can build smart playlists automatically based on rules you set (like “new 90s house under 120bpm” every month).
It is just a tool to make working with your existing local/Apple/Spotify/SoundCloud library faster and more creative.
I'm currently working on Academy Referral* (https://academyreferral.com). It's a referral platform for martial arts academies, allowing owners to reward their students for bringing in new members.
I've trained martial arts for a few years, and have always been that person who tries to introduce those close to me to the community. I know a lot of other people do the same.
Now, I don't care that I wasn't rewarded for it, but why not? We have point-based programs for nearly everything. Why not for martial arts as well?
* Have a few academies in the process of testing it out. Still a lot to do, including the demo video that isn't going to load on the main page.
I was recently looking for a simple minimalist app launcher for iPhone that would respect my privacy and didn’t come with a stupid subscription plan, so instead I made my own!
https://apps.apple.com/us/app/applist/id6743515756
Just downloaded this. This is a great format for how my head thinks, especially for apps I use periodically but not so often that I want them on the main screen. Thank you.
(Minor note: The Setup Tutorial says, "Swipe right to continue" when the user actually swipes left.)
I've been writing a software synthesizer, I want to use it to make an album when it's finished. As of now I've implemented a basic subtractive synth with the usual primitive oscillators, random noise, high and low pass filters, and an ADSR envelope. I've implemented input and output "drivers" for Windows and Linux: WASAPI, ALSA, Windows Raw Input, and evdev.
Soon I'll start work on Lua bindings. The idea is to configure the core engine programmatically. Hook up inputs, modify synth parameters, route output. It's going to be inferior in every way to something like SuperCollider, but I just think it'll be insanely cool to materialize music from thin air. I've learned lots.
I'm trying to figure out how I can turn hobby products (that me and family and friends are using) into real products for a wider audience. So far, I've found 2 main failure cases:
1. While I can share source code and documentation with trustworthy people, that won't work at scale: the market would get flooded with Chinese clones that re-use my Open Source software but then I have no ongoing revenue to fund support / maintenance.
2. Especially for products with a physical component, shipping, taxes, refunds, CC chargebacks etc. add considerable overhead. Plus I need to add in Amazon fees and marketing spend. And suddenly I need to charge 8x the manufacturing price, which means I either need to massively cheapen out with quality, or it's going to be a very premium product.
So I wanted to try this and it turns out you can't sign up?
simply go to the sign in button and then there is a reset password and then when you click on it , there adds an optional sign up and when you click on it , it leads you to mitte.ai/join which says Not Found.
Kind of interesting, wappanalyzer shows its written in erlang?
So are you raw dogging erlang or maybe elixir or gleam? What's the tech stack behind this.
Where are you generating the images / videos at? Are you using something like openrouter api or are you self hosting the gpu / using aws for it??
I am also interested in what percentage of users are paying? and also the abuse vector that might arise from generating some pretty down bad images... , are all images that are generated here public or what exactly??
We need a better mechanism than this for testing the abuse system, because I use proton mail and though I have a gmail, I don't want to use it anymore... I know Oauth is convenient, but please for everyone's sake, can we guys not either add literally every single Oauth / I think one of the best options is probably matrix OAuth with a captcha and rate limits
Seriously, I don't mind a sign in option, I just don't want to be forced to use gmail / inferior privacy solution to use your app, no offense.
> Please add more Oauth solutions
> I am investigating what can be the most universal Oauth solution while still preventing spam unlike emails, sounds interesting enough of a problem,IDK
Sounds like keycloak can sort of allow some sort of decentralized option or have many and I mean many including the matrix sign in as a option.
Keycloak also has strong integration in a lot of languages, there are other projects like authelia etc. but for some reason keycloak actually seems to me of having a little bad ui but still absolutely great in what it does
But authelia/ authentik are easier to host/integrate IDK
Whispers is a self-organizing, belief-driven mesh where nodes propose, verify, and evolve solutions through dynamic, decentralized consensus.
Basically a shared knowledge graph of proposed partial inferences in CRDTs using verification as a merge function. There're some issues I know I'll run into with e.g. admissibility but I have some solutions in mind.
I'm in the very early stages but I think it's a simple idea so I have high hopes for a cool demo soon.
I'm working on a site that lets you tile and watch multiple videos from different platforms all at once.
You can drag and drop links from YouTube, Twitch, TikTok, or Kick --and they show up in a grid.
You can reload or remove streams without refreshing, save mixes for later, and share them as links. It works best on a really big screen --phones aren't really supported and even notebooks are too small to get much benefit.
There's no backend, no login --everything runs in the browser.
A custom Python/Django based mini-app (mini — at least for now) that will allow me to import transactions sanely and safely to my local GnuCash install.
I’ve been doing tedious manual entry for a bit over two years now and after having missed three consecutive months, the only other option was to bail.
As a start it should help with 3 main things:
- Translation, categorization: my source documents aren’t in English but my GnuCash entries are. This is one of the reasons I don’t use the built-in imports. (This should shave off at least 90% of time spent entering data)
- Human-error prevention: there were at least 5 times where it took me over 15 minutes to reconcile a discrepancy because I entered some number or some account wrong somewhere.
We use data from club & sponsor to measure conversion over time.
Our challenge lies in attributing a select group of people who appear in both datasets. Sponsors spend millions on their sponsorship, and they have no idea what comes back.
We also got funded last week & looking for a founding engineer (2nd employee) :)
Writing well is hard and takes time. Was it Mark Twain that said "If I had more time, I would have written a shorter letter."? I can totally relate to that this month. Getting your point across without being long winded is challenging.
Chrome extension to organize web-based learning into journeys. Uses the tab group API and sidebar to bundle a set of websites into a "container". Sidebar tracks progress through visiting the pages. Requires an LLM token for generating "packets" from a prompt. Requires s3 bucket token because it generates web sites just in time.
Billing. Subscription plans and invoices in micro services architecture.
I honestly hate it at this point and would appreciate any reading on the topic. It's been a grueling 4 months of back and forth with a lot of mission critical business aspects to handle that I had to learn on the fly.
visionOS app for adding a spatial component to real estate pre-listing checklists. a for-fun prototype to demo how helpful it can be to tie standard form data to a physical location in certain use cases
I've been working hard on MCP Router. MCP Router is a free desktop app (Windows/Mac) that lets you securely manage local or remote MCP servers via GUI, with access control & logs.
I'm working on a multicast dns implementation in OCaml. It's a library allowing one to build custom queries/responders, plus a conventional querier that can be used as a stub resolver for .local to get the resolver functionality of avahi.
My main motivation was to implement a service that publishes the addresses of containers and vms that I run on my workstation to my local network, but it gradually has grown into a full-blown implementation of RFC 6762, which has been fun.
I'm working on a mobile app for exploring places with Wikivoyage (https://mapvoyage.app) and a wikitext to structured JSON-tree parser to support that (https://github.com/bcye/structured-wikivoyage-exports) and am finally getting pretty close to a beta version :) I hope to unify the workflow of going back and forth between Wikivoyage, the favourites list on Google Maps and notes into a single app.
So far it has some sort of activity calendar + expense tracker
There's still so much ideas to implement, like adding map, improve UX of creating activities, to-do list, etc
I've used it once or twice of a short trip, but in 6 months time, I'll have a 2-weeks trip, so that's my self-imposed "deadline" for this project
Anyway this project is a pure static web page and all the 'back-end' is handled by InstantDB ( https://www.instantdb.com/ ) after I saw their submission on HN >.< So far it has been quite a good experience overall except maybe the permissions model which can be a bit confusing to me
Awesome project! Which other alternatives did you find/get inspiration from? I haven't really found great options in the (more broad) travel planning space, which is why I am building in it.
I'm looking for an open source system that has the following features.
Forum for questions and answers.
A section to upload video tutorials
A way for experts(teacher) can upload their own series of videos.
Basically looking to clone laracasts.
If I can't find one, that is what I'll be working on.
Rebuilding most of my serial literature + newsletter service for fiction writers because I used FaunaDB for both DB and authentication and now they are shutting down by the end of May.
A semantic music visualizer :) real-time capture of elements of music —- not tracks but true elements —- paired with time-stable frame generation for display. It likely won’t be as good as a real VJ, but I want to outshine all the visualizers which are basically a demo atop a grapheq.
Fantasy consoles are awesome, very fun project and I love your demos. The way the bombs fall with the music in Kaboom is smart. I've thought a lot about building a hardware PICO-8. Not just running the software, but implement the APIs for real hardware and transpile the game cartridge. One of those ideas that will probably forever stay in the back of my mind.
The experience with GitHub can be terribly frustrating when it comes to managing the stream of incoming pull requests. The default inbox and notification systems are not so good, and not flexible. Critic allows to create any number of sections, each section being defined by an arbitrary search query.
I would now like to expand it to provide a better code review experience, similar to what Graphite or Reviewable may provide - but under as an open source project. Source code is available at: https://github.com/pvcnt/critic
It’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. The first two cards are unsigned, and the last one reveals who sent them. It’s meant to be a slow, kind surprise in the mail.
I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!
Just some feedback, I think this would be much more compelling with better choices of messages. It feels like the first two words are setting something up and the third should have some kind of payoff, but a lot of the messages don't work like that. The third word is usually predictable and obvious and something of a letdown "Never give....up".
There's really nothing in that list that is interesting enough to send to anyone in my life. I'd be wanting to send something very specific like "Remember cycling Iceland?" or "Soy chicken success" or something.
I get your concerns about "writing something inappropriate" but you could probably let people choose 3 words from a list of a few hundred pre-vetted words?
thanks for this genuine feedback, it's really helpful insight. i like your idea of pre-vetted words and imagine there is something i could do with an LLM to moderate user generated messages.
Learning iOS development by building a the habit-tracking app I wished existed - habit tracking has been done to death, but I couldn't find anything that worked exactly the way I wanted, so I figured I'd build it. I've found Swift / SwiftUI alternately delightful and infuriating so far. Most of my experience has been with web tech, so it's exciting to build something that doesn't run in a browser.
It's inspired by VS Code and hopefully positioned to eventually be a Cursor-like experience for transactional lawyers. The LLM integration isn't baked in yet to keep the in-house onboarding frictionless.
It's a desktop application written in Rust. It uses egui (an immediate mode UI library) for speed.
I work a lot with smaller investors, in real estate, private money lending, etc. It's sometimes hard to do due diligence on someone, and after having a couple bad deals and realize over 30 people were scammed, I wished there was a simple review site where you could see someone's past reviews.
Site is 80% there, hoping to enter beta in the next month.
I'm trying to read a kid's version of The Odyssey in Greek and to be able to understand my partner's mum, and these are the features that I wanted.
Also, I wanted to experiment with "what would an app like this look like if we could trust AI to be very cheap/fast/correct?".
- So, for example, it's a fully generative dictionary & search, e.g. the dictionary entries/metadata/example sentences don't exist until the first person searches for them!
- You can upload any kind of content (image, audio, text), and it'll automatically transcribe, translate, annotate, etc.
I'm prototyping a Depth Anything[1] -assisted segment annotation tool, with an eye toward plant detection in non-agriculture environments (where the backdrop is an endless sea of green complexity). Even if the task I have in mind doesn't pan out, I think this tool could be useful to people for other difficult segmentation tasks.
I’m building ninja.ai — it looks like a one-click App Store for MCP Servers, but the real goal is much bigger: creating a “Universal Fabric of Context” that lets AI tools tap into structured information across the web easily.
It started when I found it surprisingly hard for my partner to install and connect MCP Servers — even simple ones. I realised if we want AI agents to really interact with the web, it needs to be as easy as installing an app.
Right now, you can browse, install, and connect servers in one click. Over time, it’ll make AI integrations as easy as installing an app — no messy APIs, no custom scraping.
If you’re working with AI models, agents, or data-heavy tools, I’d love to hear what kinds of “context pipes” you’d want to see added.
I've been thinking about the need for something like this. Another person told me the idea was like Neo in the Matrix saying "I know Kung Fu." I think the most powerful idea is to create unique bundles of context for specific use cases. Context A + Content B = best context for Situation C.
I am working on making it easier to learn languages. We provide a platform for teachers and educators to create their own language courses. The platform offers features similar to software like Babel or Anki, along with some unique features for phonetics study and customizing the learning experience.
We're currently working with language influencers to build courses on Emurse. This year, we launched Japanese Phonetics course created by the YouTuber Dogen https://emurse.io/course/japanese-phonetics.
If you want to try out Emurse, we have a free Thai reading course available. You can view the first lesson without out creating an account: https://emurse.io/courses.
just finished https://www.treesnap.app/ now just doing some light marketing on the daily. next project is multi-vendor monstrosity so happy to have gotten that win.
RSS readers show content based on the feed they're coming from, and show read and unread items in the same list. That makes it difficult to know which items you've already seen, and is especially annoying for managing items that you want to read at some point but not anytime soon.
Lighthouse splits it into Inbox (new items) and Library (bookmarked items). This makes it possible to process new items quickly, and take your time with reading them.
I recently started working on a fishing journal/log kind of app. I got that idea last year when returning from fishing with dad, that it would be nice if we could track what we caught each time we went fishing, where we went, and to track some details (water and wea details). There apps that already do that, and one could also use Excel or just paper notebook, so I'm making this mainly for us and his friends to use. It's still early, but I'd like to add groups so you can exchange messages or catches with your friends, add stats allowing you to see for example at what time and where you caught most fish, or using which lure or bait. The app is in Serbian though, but here's a link if you want to check it out: https://buckaros.com
OkNext! (https://oknext.io) - a task manager for solopreneurs and small teams.
I'd love for you to try it out! It is browser based only for now and pretty basic. I'm adding features sparingly as needed but my next task is to add some documentation for brand new users and making what it can already do more obvious.
A storytelling/creativity card game. I was struggling for a bit to figure out a mechanic that could make it more fun and I think I am finally making some good progress. If anyone has tabletop simulator and wants to help test, hit me up. Stephen at the domain below.
I’m making a presentation ai assistant. Existing ones don’t cut it… they’re really nice to demo but not good enough for professional use. Full MVP by next week. https://unblank.ai
I have a similar domain - https://hackernewsalerts.com - but it's for tracking replies to comments and posts you've made. It's on maintenance mode at the moment, couldn't gather as much interest as I'd hoped. Have open sourced it.
I’m working on extending Postgres to run on top of FoundationDB. The goal would be turning Postgres into a distributed, horizontally scalable database with automatic sharding and replication.
Hoping to share a first version of it soon. It’s been absolutely fascinating digging into Postgres internals!
I'm working on creating a volume mixer, basically like Deej, but more polished.
Some things I'm planning on including:
- App drag & drop for assignment.
- Programmable macro buttons.
- Small OLED displays to show app icon and volume levels.
Attempting to do everything in Rust too, even the MCU firmware. It's been a lot of fun. xD
I'm working on Damon[1], a Nomad Events stream operator that automates cluster operations and eliminates repetitive DevOps tasks. It's a lightweight Go binary that monitors the Nomad events stream and triggers actions based on configurable providers.
A few examples of what it can currently do:
- Automated data backup: Listens for Nomad job events and spawns auxiliary jobs to back up data from services like PostgreSQL or Redis to your storage backend based on job meta tags. The provider for this is not limited to backups, as it allows users to define their custom job and ACL templates, and expected tags. So it can potentially run anything based on the job registration and de-registration events.
- Cross-namespace service discovery: Provides a lightweight DNS server that acts as a single source of truth for services across all namespaces, solving Nomad's limitation of namespace-bound services. Works as a drop-in resolver for HAProxy, Nginx, etc.
- Event-driven task execution: Allows defining custom actions triggered by specific Nomad events; perfect for file transfers, notifications, or kicking off dependent processes without manual intervention. This provider takes in a user-defined shell script and executes it as a nomad job based on any nomad event trigger the user defines in the configuration.
Damon uses a provider-based architecture, making it extensible for different use cases. You can define your own providers with custom tags, job templates, and event triggers. There's also go-plugin support (though not recommended for production) for runtime extension.
I built this to eliminate the mundane operational tasks our team kept putting off. It's already saving us significant time and reducing gruntwork in our clusters.
Check out the repository[1] if you're interested in automating your Nomad operations. I'd love to hear your thoughts or answer any questions about implementation or potential use cases!
It's compatible with Settlers of Catan. However, I plan to make my own rulesets, artwork, manuals, etc. It will not be a commercial product, of course you can make your own with the files I provide.
Right now the boards, electronics, and firmware are in good working order. Although the routing is pretty YOLO.
It feels like there's a lot of unpleasantness going on in the world right now. I thought maybe I could put my other projects aside and try to make something that might brighten your day (It certainly has enough of LEDs).
A big TODO is to replace the 0402 SMT components with something larger and easier to work with like 0603. I'll find time within a week or so and push it to the repo. (I am notoriously cheap and only keep 0402 in stock)
At home... about to welcome a dog, so that's going to shrink my free time even further.
On the "side projects" side of things, I've been working on a "boot to EndBASIC" disk image since December with the goal of creating a small "dev kit" box that boots quickly and directly into the interpreter. The disk image is pretty much done for a first release, so now I need to get to the design and 3D-printing of a case for the board+screen combo. The latter is brand new territory for me, and I have a self-imposed deadline of June when I'll be presenting this at BSDCan.
... but I've also taken a small detour to improve the EndBASIC website and provide a dynamically-generated gallery of user-uploaded projects. This has been a deficiency for a while and I felt it'd be easy to add it, right on time for the "dev kit" release.
I am working on a direct competitor to Netsuite. I’ve worked on ERPs, accounting, and inventory long enough to think I can do it. And with AI I can make progress on this in a way that would have been unfathomable a year ago.
I started experimenting and I think this builds out pretty neat estimations from jira tickets/other descriptions. When I was sitting in the CTO role, I spent a ton of time talking with people about how long/short various projects would be. When I was a developer, I hated the estimation piece because it felt like it was both keeping me from building and was almost never done with enough context to get really accurate results.
I was playing with the OpenAI API and I noticed that they can actually return a set of probability x next tokens and I thought that it might actually give you kind of cool ways to see the distribution of potential outcomes. (You can see an example here: https://universalestimator.com/estimates/c68db45b-7622-4bab-... that looks at a detailed ticket for implementing filtering on a dashboard.)
Let me know if you have any feedback, it's free with the promo code TYHN. If you run into any issues, please send me an email at earl@unbrandedsoftware.com
Right now, it asks you some follow up questions and assumes you're a medium sized org, but I'd like to start to move that into configuration and do some sort of time/bayesian expiration of memory/information as part of the questions it asks.
I think a ton of the variance between teams is probably captured by some version of a few calibration questions, aka:
- How large is the org?
- What region is your org based in?
- How long does it take to get the smallest possible change into production?
I'm working on a better frontend (in sveltekit) for Udio - music generation app. Udio has good models to generate audio, but awful UI and organization/management tools. My frontend allows collecting all the generated content from udio, organize them by topic, rate them with 5-star rating system, add custom labels, filter by these, make playlists, generate prompts and create an arbitrarily long generate queue (udio allows you to create 4 prompts simultaneously so you can sit in front of UI babysitting it if you don't have custom tooling and you want to actually use your 4800 credits you paid for). I use LLMs heavily here, so the quality of code is so-so, but work very well for me and I'm having a lot of fun with this.
Currently I'm developing https://findl.top. Lately I've added sort of an AI-analyst, which can help to find meaningful changes from one financial report to another
I am working on a telegram bot deployed on cloudflare which is just a basic app for van drivers to sign up on a fixed location near my area and see which drivers are online and see how many people have sit in a van which the drivers can increment/decrement by just chatting with the telegram bot who want to go to a popular spot where I have to go to quite daily because I am studying at a place which is way far away and its the most economical and sane method to travel..
Yet my problem really arises that its too luck based, sometimes I can be the last guy, Sometimes I can be the first guy so I have to wait for the van to get fully occupied which will take a lot of time...
I have just made it, and I find it pretty nifty, I made it all completely via AI and this one absolutely crazy good youtube video on deploying telegram bots on cloudflare...
Also, I had seen this telegram bot ai maker idea on HN a few days ago, So I had also created a project which you can chat with the microsoft deepseek r1 post training bot for free because the api key of open router for this model is free, It doesn't have incremental streaming or multi chats, really basic, and It can generate me the code but I am not sure how I would deploy that code .. , I used to think its easy but not... ,any resources out there? (Though I want to open source this, but I am not going to be building this ai idea further because I lack time and I have to study)
Please keep posting updates about this because if I could instantly fire up a game in my browser, I would definitely pay for that and play with it all day!
I’m working on LookAway (https://lookaway.app) to help people stay healthier and more productive during prolonged screen time.
My main challenge has been making meeting detection more robust -- it currently uses both mic and camera activity, which led to a lot of false positives. In the next version I’m switching to mic only (the camera caused most of the noise) and I’ve added a way to identify which app is using the mic, so users can exclude non-meeting apps.
I’ve also added plenty of small tweaks throughout to make LookAway even less interruptive. I’m excited for the next release!
I'm working on making Anubis way less aggressive so that it only challenges the worst of the bad bots. I found a pattern that the bots can't fake client side and I've turned that into a sample rule that I've deployed to my website.
I shared this last month as well but I’ve added a couple new features since then: a weekly digest email, a list of what you’re tracking and a price history chart.
I’ve been building https://lowlow.bot, it tracks price changes on any website. I was inspired by https://camelcamelcamel.com, but wanted something that worked for more than just Amazon.
It’s been handy for big purchases I’m ok waiting for and stocking up on recurring non-perishable essentials when they go on sale. It also lets me know when something has come back in stock.
Om working om a distributed erp system. The goal being native ui in android, iOS, Mac OS, web, windows, Linux and curses with crazy fast response times. No user operation takes longer than 100 ms.
In my last week of funemployment before going back to work. I’m working on fun stuff like gardening, designing battle tech terrain in cad and building a web tool for solo roleplaying.
No Pizza On Luna, a graphic novel about a future run by AIs who have discovered that the best way to get humans to do what they want is to present as patronizing, unctuous clowns. Http://egypt.urnash.com/npol/
I’m building a small integration to take scheduled transactions in YNAB and display them in any normal calendar application. I’m hoping to add historical transactions one day as well to help with reconciling.
I once saw an idea on here[1] about putting a lot more historical information into a calendar, including past activities. It resonated with me and I wondered if bank transactions could be part of this activity layer. At the time I was working on a real-time integration between my bank and YNAB so I was already thinking about the space.
I wrote a novel in French a couple of years ago that I want to translate to English. The way I do it is paragraph by paragraph: copy/paste a paragraph in OpenRouter (Sonnet or Gemini), get back the translation, and rewrite/adjust it.
It works well but copying/pasting back and forth gets old very fast, and it would be better if the process was done inside the word processor. For some reason (various reasons) I still use Office 2003, which doesn't have any AI feature. (It does have a "translate" function but it's awkward to use and not very good.)
So I wrote a macro to send selected text to OpenRouter and replace with the response (with a system prompt that says to only output the translation, otherwise most models start with "Here's the translated text:")
I had never written a macro in vba; I got started with Sonnet and adjusted many parts with the help of StackOverflow (which turns out to have more information about vba than Sonnet...)
And finally it worked; and it turns out to be an incredible boost to translation productivity!
I love exploring data, but it always felt clunky to juggle multiple tools, write code/commads, just to import and query a dataset. While there are multiple GUI tools for databases, none are focused on raw data.
TextQuery is the tool I built to solve that. You can import CSV, JSON, and XLSX files and start querying them instantly using SQL. Want to create a chart? Just hop over to the Visualize tab.
I'm also rolling out a major update this week — adding tabs, filters, a redesigned UI, and keyboard shortcuts.
Looking ahead, I’m planning to expand support for more formats (like Parquet and ORC) and data sources (like Postgres and BigQuery), so you can import data from anywhere, and query it right from your desktop. Something like a local data warehouse. With Apple Silicon, the capability of a desktop can make it very cost-efficient compared to something like BigQuery, Snowflake, or Athena.
https://nuenki.app - a browser extension that translates sentences at your level while you browse, so you learn a language through immersion while you go about your day.
I'm also working on and off on a hardware device for blind people.
I'm working on an app for collectors that comes with an inbuilt, curated database where users can mark things as having, wanting and/or selling. It will have an invuilt marketplace soon, but currently I'm using links to external sales to cover the supply side. I'm also starting very niche by just covering Neo Geo games, systems and accessories for starters. https://sumthings.com
In little bits of free time I get here and there, I've been working on using reinforcement learning to build some better bots for my favorite multiplayer game. Project is up here: https://github.com/cgadski/autotude
So far all my work has gone into the technical side of setting up the game (a Java app written in 2010) to work as a reinforcement learning environment. The developers were nice enough to maintain the source and open it to the community, so I patched the client/server to be controllable through protobuf messages. So far, I can:
- Record games between humans. I also wrote a kind of janky replay viewer [1] that probably only makes sense to people who play the game already. (Before, the game didn't have any recording feature.)
- Define bots with pytorch/python and run them in offline training mode. (The game runs relatively quickly, like 8 gameplay minutes / realtime second.)
- Run my python-defined bots online versus human players. (Just managed to get this working today.)
It took a bunch of messing around with the Java source to get this far, and I haven't even really started on the reinforcement learning part yet. Hopefully I can start on that soon.
This game (https://planeball.com) is really unique, and I'm excited to produce a reinforcement learning environment that other people can play with easily. Thinking about how you might build bots for this game was one of the problems that made me interested in artificial intelligence 8 years ago. The controls/mechanics are pretty simple and it's relatively easy to make bots that beat new players---basically just don't crash into obstacles, don't stall out, conserve your energy, and shoot when you will deal damage---but good human players do a lot of complicated intuitive decision-making.
[1] http://altistats.com/viewer/?f=4b020f28-af0b-4aa0-96be-a73f0... (Press h for help on controls. Planes will "jump around" when they're not close to the objective---the server sends limited information on planes that are outside the field of vision of the client, but my recording viewer displays the whole map.)
I've been working on a web app that tracks ammo prices from various US ecomm merchants with the shipping costs included. It also tracks price trends and historical prices. Added some tools for enthusiasts to calculate trajectories, recoil, and compare calibers. Using rails, it's been fun and is generally a joy to work on, have learned a lot. https://ammosight.com
I've been using elixir to build an app that lets an administrator add new rss feeds, render the article titles and summaries to a single page, scroll through them and push the ones they like to a landing page as a collection to read later. Many of the sites I like don't have the conventional RSS "structure" so I have to modify my main parser and adapt it to the outliers. I'm curious, how do you adapt to feeds that don't fit the conventional RSS structure? I was thinking of just using an LLM to automate it as I keep using Claude AI to expedite the process.
Started working on a case discussion platform for students almost two years ago. Mostly for dentistry and medicine, but it's template-based so works well for other purposes (e.g. teachers, social workers, etc.). It's going well and is being used by three universities right now.
On the way, I developed lightweight image editor and 3D model viewer components, which I've open sourced [1].
A reactive notebook with managed side effects for building backend/AI-engineering pipelines.
Reactivity can update the state of the notebook automatically, so you don't have to keep track of which cells to execute again. Side effects are managed to make it easier to reason about while maintaining reactivity and ability to interact with the outside world.
My current side project is a vulnerability scanner for binaries. I do VR in my day job, so im trying to figure out how useful (or not) AI is for this domain.
Jury is still out. Getting false positives and negatives, but I can find some known CVEs!
4 years ago I made an install script that worked for Debian, Ubuntu and macOS. This made it easier to get going with them.
Over the last week or so I extended and polished that script to make it even easier and customizable, including adding Arch Linux support. The next step is to start installing and configuring GUI tools instead of only focusing on command line tools and environments.
I just used it the other day to set up a fresh work laptop in 5 minutes. Given the script is idempotent I run it all the time on my personal box.
https://www.accessgrid.com/ - The best way to issue and manage secure NFC credentials for Apple and Google Wallet via API.
No app required!
We took all of the complexity of issuing MIFARE DESFire enabled NFC credentials and made it extremely developer friendly. SDKs in most major languages (python, ruby, csharp, js, etc), developer console with request logs, and more.
the process of creating APIs for testing and automation should be as easy possible. the tools that exist nowadays for this purpose aren't good enough IMHO, which led me to build it.
I've been working on onsite deployments for https://www.keystash.io, which is a Linux SSH Key and User management system. It's been going for a while now and I am finally implementing onsite deployments as so many customers actually want to run this themselves. When we started, we really thought customers wouldn't want the hassle of another piece of infrastructure to manage, guess we were wrong :-)
Onsite deployment is a lot more difficult to make slick and easy. We've been thinking about the best way for our customers to deploy while reducing the load on our support team. So far, we are thinking about RPM's, Debs and Docker and trying to make this as close to a '5 step process' as possible.
I would love to hear people's thoughts on other mechanisms that make it easier for SRM's / DevOps to manage key platform infrastructure software.
Writing a complete API client for the Internet Archive in Typescript, with proper documentation, proper typing, unit tests and integration tests, so people can have a proper library for both front-end and back-end applications.
I'm working on a Kaggle competition about predicting subsurface models - a map of the geologic layers beneath a given area - from seismic data.
I don't expect to place competitively but I learn a lot from these competitions. I like competitions like this that are connected to physical problems and datasets (though sadly this one is largely simulated), I learn as much about the broader world as I do deep learning. I've always idly wondered how seismology worked, and now I have an excuse to dig into it.
It's also given me a greater appreciation for the "seismology" we perform in our day to day, like knocking on things to see if they're hollow, or (as I learned here a while back) the way battitores test the porosity of cheese by knocking on it with hammers.
Since my third year in medical school, I've built the largest medical education platform in MENAP. 90k+ users, 100m+ questions solved, billions of seconds spent learning across our Super App. Now working on sustainably scaling further, building medGPT.
It's awesome, exciting and impactful work. I am the first medical doctor + full stack technologist in Pakistan (250m) people, and we've helped the country move medical education decades forward.
Part of my vision is to also help revolutionize adjacent healthcare fields, as we're focused on premed, medical and dental currently for undergrads + recent medical graduates, but nursing, pharmacy, physiotherapy and veterinary school all are of great interest to me. I am a big animal lover personally.
For such markets, you can imagine that the TAM etc is smaller, but still important. For us it's a blend of mission driven and business.
Thanks for the comment! I would love to chat vet-ed-tech further, I am on LinkedIn (/in/az1b) or email: azib [at] az1b [dot] com
With 16x Eval, you can manage your prompts, contexts, and models in one place, locally on your machine, and test out different combinations and use cases with a few clicks.
Talo makes it easy to add systems that traditionally need extra non-gameplay build time like authentication, player analytics and game stats.
Right now you can drop Talo into your game or use the API directly. Importantly, I’ve made Talo easy to self-host and you can point the Unity package/Godot plugin to your own Talo instance.
My wife and I are fans, but their Finland-Swedish Vörå dialect is not easy to understand, especially for us in the very south of Sweden. I have watched the recording too many times to count, and made these so she could enjoy it more.
It gives you a ranked list so you can quickly spot the strongest candidates, or at least get a solid starting point without reading every resume manually.
It scores applicants based on job requirements, flags any concerns, and suggests interview questions you might want to ask.
I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the tool will run everything in parallel while caching as much as possible.
If you are a small to mid-sized team, moving to Bazel is massively painful and basically requires up to one full-time position to provide your team with a good experience.
Grog on the other hand let's you keep your existing build setup while just parallelizing and caching it. It's not a full replacement, but it's more than enough for most mid-sized teams that want to have fast mono-repo builds.
A simple LLM client, for the simple reason that the one I bought stopped being supported and I could not find any replacement.
It's free, right now only for Mac (Windows coming soon when Microsoft finally decides to approve my account).
You just need an api key from your favorite LLM provider (right now it supports Gemini, OpenAI, Deepseek, and Anthropic).

Trying to use genetic algorithms to evolve voice styletts2 tensors for kokoro. Using Resemblyzer as part of fitness calculations. Results have been interesting with over fitting occuring where the voice sounds horrendous but scores high (usually later generations). The funnest part has been exploring how it all works and finally committing to a Python project.
Working out some smaller bugs of my meta tags checker / builder HeyMeta, which I've rebuilt in Svelte (prevously used Node.js for both FE and BE and it was buggy as hell)
Also revisited and updated Let's see, an eye trainer, which is basically a PWA you can "install" on your tablet/mobile/e-reader. I'm not a scientist, but have had some success training my eyes with this technique and wanted to make a simple app that I can share with my friends to try.
Checkra, an inline assistant for UX, copy and conversion feedback right on your site. It’s easy to set up with a tiny JS snippet and free to use - no account needed. We’re using it for our in-house product development and it has streamlined our workflow for generating A/B versions of pages and copy significantly
Worked a little on Server Radar [1] again, the Hetzner Auction price tracker.
It's my fun little project to resort to. Implemented dark mode, sorting, grouping and various layout improvements. Also added a Drawer with Auction view the other week. UI is finally fun again with component libraries and LLMs.
Oh, and I added a Cloud Server Availability [2] page as I noticed people on /r/hetzner were complaining about lack of resources. Looks like their Cloud offerings are going quite well.
I'm working on Proflect — a personal and professional growth platform that connects goals, journaling, and feedback into one flow. To help you grow by reflection, not just action.
The idea is that growth becomes a lot more intentional when you can reflect daily, set goals clearly, and get structured input from people you trust — all in one place instead of scattered across different tools.
I'm getting ready to open early access soon. Curious if others have tried combining these areas or if you use separate tools for goals, journaling, and feedback!
I'm working on a programmer's calculator specifically as a companion for legacy computer programming. It's geared toward the kind of calculations a person might need when writing 6502 assembly language. It even uses the C-64 palette of colours.
https://visitorquery.com a proxy & VPN detecting tool that does it's thing based on the specifics of a connection rather than parsing list and known databases which makes it very effective against residential ones too.
Working on redesigning my SaaS template. It uses Dokploy to deploy the NodeJS app, and Pocketbase instance within the same server, so DB reads and writes are very fast. Also doesn't use the Pocketbase client library at all, all calls are wrapped in their own API routes and everything is server side rendered.
You might ask why use Pocketbase at all, and I'm not sure anymore. I suppose the dashboard is great, built in auth is great (although I've had to write cookie middleware to make it SSR anyway). I wish there was a lightweight Pocketbase/Supabase style "backend in a box" setup that didn't push the whole client library directly communicating to DB paradigm.
I am working on a PromptLibrary (https://promptlib.prashamhtrivedi.in/) to organise my prompts and make it accessible from multiple clients (Including chatbots (via chrome extensions), CLIs, IDE extensions amongst the few).
I wanted a library to store my own prompts once and retrieve it in multiple locations (i.e. Try something on claude desktop and then once I wrinkle out the edges, load it in Roo code or claude code and use it.) Give some variables to the prompt and creating infinite versions of same prompt by providing the value. Or having the versions of each prompt.
Currently I have the landing page, soon (In max 10 days) I will make it live for everyone to use.
Taking on a fun technical challenge, building a distributed database to serve the needs of Actor State saves in Orleans. Using the guarantees around actor placement to implement something optimal for its needs.
Much cheaper to hire a VPS with attached local storage, than to use an external database and a lot quicker too.
We’re building BLUO - https://bluo.cms a modern multi-website CMS focused on simplicity and performance.
Key features:
- Multi-website management with single sign-on (one dashboard for all sites)
- Static rendering via Cloudflare KV for 100% uptime and blazing speed
- Real-time editor with AI-powered automated internal backlinks
- Theme switching without breaking functionality
We're currently serving 100+ websites. It's completely free for non-profits.
Would love feedback from anyone managing multiple content sites!
Slowly building an open-source Data Lakehouse management utility application for local development, scratching my own itch and trying to accelerate development workflows with customers developing for Databricks.
For now it only supports Delta Lake (using delta-rs + duckdb), only supports table metadata inspection and querying, but in the near future will add dashboards as code, simple Markdown notebook like mode, and Apache Iceberg support.
For now it's an enabler for me and others, hopefully I can turn it into a product somehow at some point.
Recall Audio - A multichannel audio recording app that has your back, even if you forget to hit record.
Basically it continuously records into a buffer (length is configurable), and if you realize that you wanted to start recording 30 minutes ago you can recall the buffer and have everything saved.
In my work and an audio engineer I was in this situation a couple of times, and since there was no tool for that on the market, I’m building it.
I've been thinking about this app for about 5 years but didn't build it yet. It could be used in professional and personal settings. Can you share the link to this app ?
After struggling with bloated, ad-filled debugging tools, I decided to build MyDebugTools—an open-source, clean, and ad-free debugging tool. It’s designed to simplify the debugging process and help developers stay focused. No ads, no distractions—just efficient debugging. You can check it out at mydebugtools.com, and I’d really appreciate your feedback or suggestions!
ShippentPlanner - easily plan and organize your sku paletizing! Make a shippment to a destination warehouse in minutes! For ecommerce sellers. I'm preparing a demo to be able to show to others...
Notably not an AI agent like Operator, Manus, etc. which are largely unreliable for the time being. Instead this uses AI to turn your task into something repeatable and configurable.
Currently focusing on scraping use cases but hope to make it more powerful soon so it can actually do complex tasks rather than just extracting data.
For the last months I've been working primarily on building a UI framework for Go in Go via WebASM.
Had to implement the bindings first, because js.Value kind of sucks. Meanwhile I am building web components and widgets and it's slowly getting where I want it to be.
Maybe after a couple more weeks I can finally build apps in 100% Go and together with webview/webview. Still needs a lot of work around the edges here and there.
I spent a long time working in manufacturing and struggled to find a piece of software where we could define a process, share instructions and collect data all in one go.
The idea is you can basically turn your process into an interactive flowchart and follow it through. I’m almost code complete on the MVP, moving into distribution mode in a few weeks.
I’d love to hear from any HNers who’ve gone from 0 to 1 on a SaaS for non technical users. What worked for you?
As a teacher of computer science, I'm working on various free resources for teachers and students, such as a guide to simulating forces and collisions in JavaScript (https://www.mathsuniverse.com/particles) and super simple real-time forms for lessons (https://www.mathsuniverse.com/forms). What brings me joy is seeing that they are actually useful for people other than just me.
I’m working on a review website for Generative AI. Targeted at people who want to use GenAI to build stuff.
e.g.: Following up on one of my HN comments on OpenAI ImageGen gpt-image-1 quality: Side by side comparison of more challenging prompts at Low/Medium/High:
I'm building a simple, minimalistic web-based note-taking app called tonotes.com. https://tonotes.com
It's still a work in progress, but it's already functional if you want to try it out. I'm keeping it super lightweight, clean, and focused just on writing without the usual bloat.
A bit of a mix between Pokemon Go, Tripadvisor/Wikivoyage and Duolingo.
Basiclaly an app where you can travel a city on a hex grid (h3) and learn about it/receive recommendations on things to do. Different activities and landmarks are hooked into language learning games, which when completed, add phrases/words to a flashcard deck for future study.
I am extending my pet project menuop.com, a digital menu maker for restaurants. I plan to integrate AI to enhance visual impact, analytics and recommendations to restaurant owners.
I'm still mulling how to go about porting my tiling window manager for Windows[1] to another platform, or even if I'll do it at all. There is some demand, but I don't know if there is _enough_ demand
Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so
I appreciate you enjoying the game! I work for IPinfo but initially made it as a sort of meme for our users.
I'm generating random IP addresses on the frontend, then making an call to our free API to validate the "realness" of the IP addresses — mainly to remove bogon IP addresses, non-routable IPs, and IPs from large ASNs (national ISPs, the DoD, car companies, etc.).
Our free API supports 1,000 requests per day from unique IP addresses, so there shouldn't be any issues for low usage. However, if we get more power users who enjoy the game, I’ll switch to our Lite API service (which is also free, https://ipinfo.io/lite) to validate IP addresses, as it supports unlimited requests.
Let me know if you have any feedback for me :) I made it mostly by "vibe coding", I will write a post about the whole process of it.
I work for IPinfo — I described my process of how I made the game in the other comment.
Using a dataset-based implementation would require me to have a backend, which is out of the scope of this project. Right now, I'm generating random IPv4 addresses, but if I were generating random IPv6 addresses, I would have to go the database route. For that, I would use our free IPinfo Lite dataset: https://ipinfo.io/lite
My colleagues actually developed an extremely fast algorithm to select truly random IPv6 IPs from a series of CIDRs, which is what you see reflected in our dataset.
Let me know if you have any feedback or suggestions for me, please.
I’ve been working on https://ulry.app - a simple link archiver that lets you tag and attach notes on each URL. Right now I’m working on a feature that uses LLMs to summarize an article.
This seems like it would only work if “reviews” would be something rare to come by. Like some forums where you have to contribute to be able to download attachments, or see higher level subforums.
But reviews are everywhere, good ones too so it will be a hard chicken egg problem to solve.
Taking a break from my agentic AI framework for prototypes and makers arkaine(1) and made two fun useful apps for myself
1. Eli5 equations(2) uses an LLM to convert a given picture of an equation to latex and, if given additional context, breaks down the equation parts to explain it. Gemini for the model.
2. reflecta - a journal prompting app with deepseek to help reword and target the prompts towards you better.
Working on static website hosting. Thinking about how I can build backend functionality for customers as well while maintaining the openness that the static hosting has offered.
Building a AI-assisted aviation regulation compliance tool for aviation professionals: https://aviation.bot
At the moment just a RAG with EU aviation regulations. Soon FAA, UK CAA, and more complex AI agent features that do more complex deep research.
- Shows I can use AI and I've integrated into AWS Bedrock
- Shows I can integrate with Stripe for payments
Consulting (Architecture, Strategy, Tech) - I'm working on getting my consultancy started. If anyone wants the kind of skills I offer here let’s talk https://architectfwd.com
Next SaaS - Starting a SaaS for managing core strategy and tech concepts. I created goals for it but I’m failing to kick the tyres
Last night I actually also started playing with firebase studio, though the app I prompted isn’t even doing save of the document properly. I figure can’t be me but will try again and work through the errors.
Working on my university degree. I failed my first one and now I got myself into a critical situation again. Started using Anki. I often put in the hard work of thoroughly understanding a subject but don’t profit off it because I don’t keep the understanding after that. I am working on improving that.
I'm working on an application that will help me install AppImages. The problem I'm solving is that some apps come with the wrong logo/icon. So in the app I'm building we'll be able to set a custom icon for the AppImage.
I am a tech guy, now turned VC in Europe. However, something curious and interesting I'm working on with some partners is the renovation of a Palazzo in Venice. Learning new things almost every week. Absolutely stressful, and exhilarating. Completely different from coding or investing in tech startups.
Building a foot traffic API to see the busiest venues (bars, shops, museums, etc) in (your) worldwide neighborhood: https://besttime.app
We are now busy adding more demographic data like age, male/female ratio, tourist level, etc
Did a Show HN about a month ago, but we're hard at work building dédédé [1] - it's a not-for-profit website that invites people to casually share the "good, bad, and why"s of urban spaces.
I keep adding new features to my hobby project at https://nobsutils.com
It's a collection of various tools that run locally in your browser.
The latest addition is a simple color palette maker https://nobsutils.com/colors
I am working on an open-source insurance application platform.
The main goal is to accelarate time-to-market for insurance and insurtech innovations, providing all these "boring" enterprise features (like multitenancy, role-based security, audit trails, etc.) out of the box, so that you can focus on building the actual product.
A language learning app for couples (https://couplingcafe.com). I wanted to learn my wife's native language, so I've been building this on my own for a long time and testing solutions! Just a few paying happy users. Cooking up a lot of ideas
I'm working on a long-term project to better understand Operating Systems, video game development, and Rust by building the simplest possible OS in Rust that boots directly into a game of Doom, which will also be re-written in Rust.
I'm giving myself 18 months- it's been super fun so far!
I am building https://hire.blue, its a platform for HR to reduce time to interview by 90% while being applicant friendly, this can be used as a ATS for small companies and for founders!
PostScript has two mechanisms to save and restore the machine state and they are intertwined and only vaguely documented. I'm trying to get my head around all that this week.
Sounds basic, and it is, but I've yet to find any open source project (let alone product) that does this.
All I want to tap a button, talk to the little guy about how to update my document, and see the changes flow. I guess Claude projects or similar might do this but I'm making it more for friends and family. Current use case is keeping track of a house renovation project going on.
I’m working on Catchcam - https://hackaday.io/project/199220-catchcam-speed-camera-det..., a privacy-first, offline speed camera detector for drivers. Unlike apps like Waze or Radarbot, Catchcam doesn’t track your location or require an internet connection. Just plug it into your USB socket, and you’re good to go.
Key features:
• Built-in speaker and LED for alerts
• Preloaded with 66,000+ known speed camera locations (more to come)
• Easy updates via drag-and-drop on your PC
It’s been a fun project to build, and I’m excited to see it help drivers stay away from speeding tickets while keeping their data private.
I’m working on supporting photo posts on my blog (Kirby), I bought a new camera and thought it would be nice to share them in one place (Cross post to Mastodon).
I’m still looking for a new SaaS idea, so if you have something you want to partner on do reach out. Preferably Rails or Go. Previously I built stuff like https://getbirdfeeder.com/
I'm making some minor changes to my personal site/blog to improve contrast, have a more uniform usage of colours throughout, and also replacing "categories" with tags so that I can have related content easily linked and searchable.
I may also finally finish implementing WebMentions support too as a kind of comment section.
I may also work some more on my long-term relaxation/creative maze generation and solver project.
At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.
It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.
To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.
Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".
The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.
So I guess what I'm saying is I've been casually looking around at jobs this month.
This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.
A prompt collection platform that let's you organize your prompts, share them, learn prompts from other users and reuse them on multiple LLM / AI platforms.
It's aimed at improving prompt engineering skills for both technical and non technical LLM users.
Currently in Alpha phase and actively looking for feedback.
I have working on a pluggable secret and key scanner from scratch [1]
The idea is to build scanning databases, file systems, buckets, etc. for static keys and credentials while allowing users to add new file types and parsers.
I develop Chips of Fury, a poker app for playing privately with friends. Currently I am building support for lots of home game variations like pineapple (regular, crazy, lazy), different Holdem variations like Super, reverse, super reverse, blind man's bluff etc and many more. I am thinking about how to implement AI bots for a wide range of variations.
Ah, I've made the same!
I made a very flexible turn-based framework - write the game logic on server in javascript, then state+options are given to clients, so platforms (swiftui, web, unity, webxr etc) "just" have to implement UI on top (Also means I have a default/debug view, which works for all games).
The games can run offline (via javascriptcore on ios, natively on web etc) and supports bots for all games (they randomly choose options on their turn) which has a very simple opening to get some reinforcement learning in.
Then specifically I was making an app which let me customise rules for poker - extra streets, antes, throwaway cards, passing cards, multiple boards, multiple decks, etc to support as many variants as possible, and ideally, stumble across new ones.
As an aside, I posted to reddit for research of other home variants people play (Basically to stumble across more fun variants in our home games) there's a few good alternatives I've not heard of in here!
I've run out of steam a little bit (burnt out & seeking work isn't great for own projects), but has been an excuse to learn swiftui. I'd be tempted to team up with people to keep the project alive...
While Git is great at asynchronous collaboration, its a bit clunky to try and work on the same commit with other devs or across devices.
This is because Git tracks what changed, not how it changed.
It'd be cool if you were on the same branch as somebody else, or another device, and your working directories could be synced.
It'd also be cool for the commit history to be a bit richer, so you could see who, what and when for a change at a keystroke level.
So I'm working on real-time sync for Git!
I'd represent the working directory as a tree CRDT [1] and sync that through FUSE and p2p networking.
Not sure whether this is actually a good idea! This is a POC :)
One idea I have had for years is that it would be great if file system would support structured data.
This would combine well with your idea.
So let's say that I change python source code, the "file system" would understand the syntax of python source. Your tool could then use this to derive the sematics of my change, i.e. "added a function foo() with the following signature and body"
It's an website who's goal is to make it easier to find apartments/hotels/etc that fit your housing preferences (starting with places that are close to the people and things you care about). It's flagship feature is the ability to make heatmaps of cities based on your preferences.
Since February I've slowed down on feature development temporarily as I try and find a way to sustainably increase it's popularity and learn what's the most important thing to focus on next.
Schematic and PCB design relating to Lighting and Control Systems for my main job. Schematics and PCB Design after hours as a contractor too, because I have a daughter now, my wife can't work, and life has become /very/ expensive in Sydney.
What I'd love to be working on: Try to initiate a high voltage arc through the air to a target device, and modulate it to send "Data over Lightning", like Alyx does in Half-Life 2. It won't work the way it does in the game, but I'd it's an idea I've had for a long time and I'd love to prototype it some day.
The first is a preventive maintenance and calibration tracker (https://pmcal.net) that was born out of my day job as an engineer in small business manufacturing.
The second is an AI engine for pulling structured data out of incoming email (either via IMAP on your email server or via SES). If you think of the engine that powers TripIt, they had to write about 10,000 different ingestors for each airline and hotel and travel booking site. With a structured output AI, the need to write specific ingestors goes away.
Honestly a little bit hesitant to say anything yet. There are a few more features to add, and a whole lot more work to be done to showcase just how cool it is. But the short version is, I'm working on a sort of meta-pico8, a game maker for WebGL2 2d pixel art games (e.g. 320x180 games like Animal Well) that runs in the browser, but one that's firstly collaborative, so that we can all build it together. And some of the coolest features are the based around that. For example, I got arbitrary imports of user code working in the browser, so all you have to do is create an account, add a JS file, and other people can import it as if it were a built-in module, and it just works. Plus the SDK I ended up making is simple, and the API is clean, and there's a few innovations in the GUI layer that I'm excited to share. I wish I could explain just how cool this is.
Interesting, I have been working on a similar project, albeit 320x240.
I also got some code-share and collaboration features working, but got a bit stuck on fonts. But I can appreciate your feeling of 'how cool this is'
I ground to a halt once I realised I had no barrier to entry, ie it could be cloned very easily. Always an issue with Web Development I guess. Plus I hate what modern browsers have become in recent years and not sure I want to target such a fast moving platform. I got burned once already with WebStart 'warning this app might do something scary' and certificate fiasco.
I thought about some native binaries, but I know I am kidding myself. I had an ios app that was pixel cloned within 6 months. But somehow a web app feels like publishing straight into public domain.
It's not just the web, native apps have always had free open source clones that technically render them useless, often just as good quality, yet they didn't go out of business. There are other considerations people make when deciding to use an app, including network effect, a strong community, sheer level of quality and passion from the developers, etc.
For fonts, I just went with a simple raster bitmap font and pixel grid storage format. Creating these limitations makes it easier for me and for developers and artists. I choose 320x180 because it fits the 16:9 perfectly, which would make full screen ideal on most monitors.
I'm working on a workflow automation tool that lets devs write workflows in simple yaml files, and then deploy them to the cloud _or_ on premise. Each workflow is a set of actions and a trigger that can transform data, make api calls, run AI models, or really anything (via docker!). Each step relies on the output of the last step, and the workflow framework is engineering to be declarative, testable, and versioned. Similar to GitHub actions, but for *anything*. Think webhook to slack, email to support ticket, nightly aws backup & restore, mirror a file each night, etc.
It only stores (timestamped) floating point values with a series id and uses a B+Tree as the backing data structure. Querying is done with a lisp-like query language.
I updated the catalogue of movies and added some internal tools to my movies released on YouTube website: We Love Free Movies (https://welovefreemovies.com/). It's hard to share it because it gets flagged because of the name... But yeah, planning to add search, design touch ups, more movies, etc. this year.
Also working out the logistics of offering a microgrant to award people who want to make movies like this!
I’m working on https://vimgolf.ai, to help me learn new vim commands and in doing so hopefully help others. Right now, still working on adding the ai assisted level creation for each motion, but more to come on that.
Is it possible to add an interactive challenge or two on the homepage prior to sign up? I think that would hook people in and make them want to sign up.
Good idea, currently I spin up a 2 neovim instances for each challenge, so can only spin up so many at once with my current setup. But, am moving to a kubernetes setup where I can scale up and down the number of neovim instances more reliably and will add that in then.
I have, but all the JS vim clones are emulations of vim, and don't support all the vim motions (like copying from registers, etc). I honestly could do that and it would be easier, but doing it this way, also allows me to record the keystrokes directly from the neovim runtime.
Mostly just exams this month haha, but technically a self-hostable workout tracking app.
The only self-hosted option I found was wger.de and while it looks great, it's a bit too much for my needs. I want something lightweight (so as not to hog resources on my cheap VPS) that does what it needs to do and nothing more.
It's been a while since I've done web dev, so I'm going to try out Deno (TypeScript) with htmx.
A merge conflict resolution tool integrated with GitHub. Now working on a solution for preemptive conflict detection and a smarter/simpler merge queue.
Trying to make interpretability research practical. A bit early for the demo, but I am getting some interesting results for large multimodal models in terms of their reasoning.
A sales co pilot that helps startups move deals faster.
You can think of it of Cursor for sales. It knows to perfectly summarise deals activity and prepare the next action. Saving you precious time and enables you to close more customers faster
I'm working on a correlation matrix with Svelte 5.
It has hierarchical clustering, rolling correlation charts, a minimap, time series data detrending, and 2D matrix virtualization (to render only visible cells to the DOM).
It has up to 130K matrix cells and correlates up to 23.5M time series data points.
I would love to see some UI/UX improvements like split view where the map is on the left and the news reading/scrolling happens on the right reading pane instead of on the bottom while horizontally scrolling.
You could even use AI/LLM's to summarize the most important news from each country etc.
basically a user give an initial prompt ie "create a game" and then a series of ai (gemini, openai, claude) prompt themselves until a finished outcome. the user can change any output step in between so the end result can be tuned instead at any point
Very early stage, no link, but I have been working on getting terminal fonts (like Cascadia Code) to work in the browser more progressively without requiring such a giant single download, and on using them for text-based animations. One of those unimportant, low-stakes kind of projects that makes it relaxing to work on :P.
I'm working on platform that helps you vibe code APIs. It'll generate clean, scalable, maintainable monolithic backend APIs built using Express + Postgres.
Launch soon! Drop a comment if you want early access
[1] Surveys. Thinking about how to tighten up the onboarding experience, improve brand awareness, improve in-app data analysis, and how to integrate AI in new and exciting ways... and handling customer support tickets!
first order zero knowledge proof system (zk-stark), it works on android, macos, linux, webassembly, vulkan/cuda backend (metal coming), but the composition polynomial evaluation is suboptimal so i am working on that now
I'm working on a distributed object storage system to be the backing store behind my website (https://scmscx.com). It currently uses back blaze b2 which is good and cheap but I thought it would be fun to roll my own.
So far this has means orchestrating a set of processes just to talk to bluetoothd, automatically connect to boards, guess which /dev/input/event* device each one is associated with, and start reading those and sending data somewhere over OSC. Every step of the process is about 10 times as difficult as I initially expected it would be, which is why, after months of work, I'm still putzing around with process orchestration instead of actually doing anything with music.
The bit of hair on this yak that I'm currently shaving is building a TUI library for Deno so that I can build a nice dashboard for keeping tabs on the state of all the different pieces. I prototyped a bit of the orchestration process in Node-RED, which was neat, but not exactly what I'm going for. There is a TUI library for Deno already, but it's kind of buggy and non-ergonomic for my brain.
I'm working on a desktop-based, performance- and privacy-first note-taking app that lets you quickly capture notes from any selected text using hotkeys.
I'm curious: what are your must-haves in a note-taking application?
I thought about doing something similar some time ago, because I never quite found the perfect note taking app for myself. There's a million ways how to do notes, and it feels like there's just as many different notes apps.
Eventually, I've settled with Obsidian because of its simplicity and extensibility. You can leave it with basic features and truly own your notes in a simple format (you can also put them into any cloud, as long as that cloud reaches your filesystem). It doesn't do everything just like I'd want to, but I've thought about just building another notes app that reads and writes to the same path your Obsidian notes are in, instead of trying to cover every possible editing feature like most big notes apps. Then I'd use different apps for different needs, with one place to store data.
Since you're focusing on privacy, have you considered using Obsidian? Is there anything particular you want to do differently?
Basically I want to build it with focus on speed and work efficiency from start. To not bias myself too much, I will refrain from doing too much market research. First of all I'm building this for myself, and I'm guessing it might translate into at least a tiny market share.
Building a tool to supercharge your Cursor, Windsurf, Claude and other developer tools by connecting it to polished, high quality mcp servers for linear, slack, DBs, and other useful workflows.
Great work, I've been using Stock Events on iOS for a while now. It's what got me into dividend investing, and it's fantastic to just keep track off all the dividend income.
Last year, I repurposed an old laptop into a simple home server.
Linux skills?
Just the basics: cd, ls, mkdir, touch.
Nothing too fancy.
As things got more complex, I found myself constantly copy-pasting terminal commands from ChatGPT without really understanding them.
So I built a tiny, offline Linux tutor:
- Runs locally with Phi-2 (2.7B model, textbook training)
- Uses MiniLM embeddings to vectorize Linux textbooks and TLDR examples
- Stores everything in a local ChromaDB vector store
- When I run a command, it fetches relevant knowledge and feeds it into Phi-2 for a clear explanation.
No internet. No API fees. No cloud.
Just a decade-old ThinkPad and some lightweight models.
I’m working on a simple app that logs Karting activity and data. My son has been karting for a year or so, and there is so much data to collect - times, pressures, sprocket set up, track location, weather and more (about 30 datapoints a session)
Collecting the data helps with recording engine performance, tyre ages, best lap times but is also really useful for recalling how well each setup performed for future reference.
I’m deliberately doing this all in a very low-tech way as my son will be creating a more polished version for a school project. We’re front-running that a bit to give him a good dataset and explore various ideas.
On that note, they do Python in school. For the backend it will be SqlLite and Flask. Any suggestions for the front end tech? This will mostly be forms- and grids-based so nothing sophisticated needed, but some simple client-side logic (e.g. validation, geolocation, simple stop watch) would be good. Ideally this would be python as well. We could use WebAssembly but am wondering if there is a suitable framework that does the is out-of-the-box.
I'm actually really interested to see how other people are coding with LLMs. I guess this sort of thing is already happening on youtube and I could have searched it out but I did not. Will checkout your channel.
I am particularly interested in seeing how you handle the transition from LLMs doing great at one-shot prompts but then struggling as the scope of everything expands and you have to get smarter about breaking down problems.
Working on an electronic dictionary for my sister. She wanted something to look words up in Italian that wasn't her phone, and well I like a project. E-paper display, snapdome keyboard, an ESP32 to round it out. (Runs lisp.)
Pictures at the link. There's also some webtoys on there, feel free to peruse
When I read books, I find myself getting easily distracted since my phone has so many alternative apps/things to do OTHER THAN looking up a word in a dictionary.
I'm building an MVP for an "AI bedtime stories" app. The idea is that you just input the character names, a theme, and choose a voice (including the option to clone a parent's voice for narration). It generates a story and reads it out using TTS.
There are already a few services like this, but most don't support using a parent's voice, and very few can connect stories together into a continuous narrative based on previous ones.
Also I would like to hold context for fairy tales kinda local. For example Polish folklore is different than British. Most common villains are different and it can be fun and educating problem to solve.
I'm mainly doing this as a learning project, but curious to see where it ends up.
I work for an asshole, it's been 4 years but i can't find any other job (frontend) i found the job when i was 17. i hate it so much that i don't have any will to code on other things but lately i have been learning more low level programming like c and doing shaders using c.
Building a simplified inexpensive <20 nanometer accurate vacuum-tolerant positioning stage for microscopy and lithography projects. Trying to unlock the caveman achievement by keeping tools/budgets necessary to replicate the work accessible for other hobbyists.
Also still working on a custom Slicer for a special metal printer design. The VTK library version needed replaced by a simpler Blender Geometry nodes solution to extract texture information, and infill hull features.
Also considered a beautiful solution to Roger Penrose's Andromeda paradox. That guy has a wicked sense of humor... very funny. =3
Still cracking away CodeVideo, a way to create software educational content in a declarative manner. Design your course once, export it to every format you can think of (video, PDF, markdown, HTML, and more). I was recently inspired by the feature set I saw at Scrimba, so we just added slide functionality! The blog post is here: https://codevideo.substack.com/p/introducing-the-slide-displ...
I'm working on a running app. Mainly for me but others have expressed interest.
It's a performance analytics platform for runners who love to dive into the details after they've been for a run and to be able to accurately track their progress over time.
It's not like Strava because I'm not including any social elements, intitally. And not like trainingpeaks because it's focused on individuals as opposed to teams or coaches. Also the analytics and models I offer are peronalised as opposed to one-size-fits-all. It's also running only. No cycling or anything else.
Ideal target market would be fairly decent amateur runners (e.g. sub 3 hour marathoners) who already know quite a bit about training but don't have a coach and are not good enough to be pro and have a full team doing this stuff for them. The pros have awesome tools but sadly most are not available for us mere mortals BUT I can build some of them! Example features:
1. Personalised "adjusted speed" models. The strava GAP model doesn't fit very well for me and many others, so I've made my own personalised model which gets updated each week. If you get better/worse at running up hills then model adjustments take that into account. The idea is not to provide a physiological correct model but more a performance based one.
2. I'm trying to do the same for surface types, heat and humidity as well. Of course these models are not personalised. I'll get to wind later on as it's much more complicated than the former. The idea is to have an accurate representation of "effort pace", which you can use as an input to performance models.
3. Using adjused pace data I will offer a pace/duration model to estimate critical speed/LT1/LT2/VO2max and this model forms the basis of tracking progress over time. Clearly most training wont be all out efforts, so I also estimate race performances based upon current fitness as well. E.g. if you ran X speed for Y time at a sub maximal effort then you can estimate what a maximal effort would be based upon the remaining aerobic and anaerobic power. From reading sports science literure, this is the most advanced way to track performance at the moment. The actual model I use is called an omniduration model.
4. I also have build some other models, e.g. Daniels running formula, which can be used but I don't find them to be as useful as the omniduration model.
5. I'm also trying to model how a workout or training session will effect your fitness. Where it's base/aerobic, threshold, VO2max or an anaerobic effect. Then, the idea would be to look at future training performance to assess whether the model was correct. You can then assess which types of training you respnd best to as well as which types of sessions you need to get the performance gains you need for your next race.
6. Specific race time predictor. Most platforms offer a single figure prediction for a distance but I want to offer specific race perdictions which take the course and weather into account. The model will give you splits taking all this into account.
7. Cohort adjusted performance models. How are you tracking against people your age? But more importantly, how are you tracking against people doing a similar volume and type of training to you? Are you improving at a similar rate?
There's a tonne of other stuff I can add but I'm going to keep it simple and focus on performance modelling for now because no-one seems to offer any decent tools around this at the moment.
If anyone found this interesting then I'd love to hear any feedback - let me know. Cheers!
I recently got into embedded development and built a small 12V Bluetooth relay that lets me start my ATV without a physical key. I shared it with some friends, but mostly got blank stares and a few "but why?"s. ¯\(ツ)/¯ I just don't like carrying keys.
- we ship with a mounting piece that is easy to put on any bike frame to mount our battery
- our app and communication protocol is open-source, and we provide code for compatibility with the major bike controllers, meaning we're compatible with 90% of the e-bikes!
so in practice we're the perfect battery for e-bike enthusiast who want to change their battery to a repairable and fireproof one
and we also do B2B deals with some brands who want custom design etc
but basically if you are running Bafang / Shimano / Bosch controllers, it will work with our battery
I am also working on the last few remaining issues of Hyvector, of which some are surprisingly difficult to solve and AI unfortunately cannot help me a lot.
I've recently added autobatching to my SFML fork (https://github.com/vittorioromeo/VRSFML/tree/bubble_idle). Drawing multiple objects that use the same RenderStates will now be automatically coalesced into a single draw call, for example:
for (int i = 0; i < 10000; ++i)
renderWindow.draw(sf::Sprite{/* ... */});
This (opinionated) fork of SFML also supports many other changes:
- Modern OpenGL and first-class support for Emscripten
- Batching system to render 500k+ objects in one draw call
- New audio API supporting multiple simultaneous devices
- Enhanced API safety at compile-time
- Flexible design approach over strict OOP principles
- Built-in SFML::ImGui module
- Lightning fast compilation time
- Minimal run-time debug mode overhead
- Uses SDL3 instead of bespoke platform-dependent code
The target audience is mostly developers familiar with SFML who are looking for a library very similar in style but offering more power and flexibility. Upstream SFML remains more suitable for complete beginners.
BubbleByte is a laid-back incremental game that mixes clicker, idle, automation, and a hint of tower defense, all inspired by my cat Byte’s fascination with soap bubbles.
Browsing jobs nearby and watching old movies to gather ideas on what to do next, getting as many documents as possible and making copies of them, and updating eye prescriptions and dog and cat shots.
streamlining the house to save money and sanity when we both start working and/or going to school
and starting to seriously start using a simple phone book
and mentally preparing for rent to go up or a car issue by causing controlled chaos and finding new ways to calm down as a family with as little money and energy as possible
by watching old movies from movie Madness, we're gaining insights into the origins of the items we use today. The futuristic visions of the sci-fi pioneers are serving as a Wikipedia of sorts, helping us break free from generational curses and regain a sense of control.
since it helps because, understandably, not being employed makes us feel ultra vulnerable, and that is not only normal but what the tech cults thrived on, but it is insane to take out our nerves on each other constantly and or/the animals. And to be on mass amounts of pharmaceuticals or heavy drinking is no walk in the park either in terms of ROI on keeping the embers of love and growing old, but Gandalf/Sith Lord grandaughter redemption President signed letter die at 102 years old happy clearly an attainable trajectory
As my upcoming birthday approaches, I can't help but feel that it might be the most special one yet. despite the tears, anger, and losses, I feel some reality based it is gonna be hakuna Matata SophiaG20
while zero jobs I see and know about are for me, I'm content knowing that my brain's imagination, creativity, and curiosity machine is still growing at 36. And feeling bad ass
read an article from Wired about Patricia Moore and honestly thinking about how Empathy and how the need for tech to let the ones like my mom freaking out and having plastic surgery and going overboard on Facebook and freaking out over menopause because she's 20 years older than when most of the women in our direct family died
I am inspired to find a real way to a home we actually own, a home we feel we have worked and earned. I am also motivated to soften the blows that life inevitably brings, such as the possibilities of allergies due to eventual menopause or the loss of a loved one. I see myself working for me and the current and women who are girls right now.
So tech will be more on their side not telling them to worry about the outside while the inside rots or worse something is off and no one cares or listens.
I am navigating these challenges on newly Medicare (newly disabled) and still finding ways to go back to the default feeling of being the fierce queen that I had when I was 5 years old with my grandpa.
but also letting the mind wonder so that others will be the fierce queens that they are because that is how my grandfather and his team made things after being POW in the holocaust, and he would want it for me and my badass mothers. Not to follow in what he did but find my own path for my own tribes with our own ways.
It feels like a rebirth of some kind for the trillionth time, but this time sober with a family (who loves me and I chose) and less toxic companies in my subscriptions or emails (because I nuked entirely the old Ecosystems which is making taxes pretty astonishing) like the intro to Hackers. Still, I killed myself online on purpose, crying and laughing, saying: don't threaten me with a good time On a Pixel and Samsung phone and Apple phone while Microsoft and all of them were like, NOOOOOOOOOOO!! ~ 20th Nov 2024, and it feels like that was a sinister evil evil Cult, but damn, reality tastes crisp, and there is more to chop to make it to 102. With the vibes still fresh from the interesting dozens on dozens of 100+ year-olds I took care of when I was 14-22 years old in Alaska and coming to terms my grandpa who I was TWO peas in a pod was one of the architects of DARPA and architects of NASA, and that is fricken cool
but now it is time to start pulling in the resources for this growing family instead of being salty about wasted time in Cults moving forward, like my father and grandfather's visionaries. I am finding a way forward by choosing not and withholding this visionary raw energy from DARPA and NASA because, in the end, all the promises they gave my grandpa did not happen. at. all.
And being cool with the fact that I will learn how to live life without ADHD meds even though it has been an option since I was 5 years old, but like the olds who came off Prozac recently, I want to start life anew without that stuff. 15 years is enough to say that shit wont get me to 102 years old comfortably with the family and loved ones knowing I'll be fine if 5-20 terrible terrible things happen back to back again.
I am about to begin a PhD in astronomy. Until last month I was working at Caltech for 3 years on code which calculates orbits of asteroids to high precision. This code is being used on several NASA telescopes now to predict when they will image known asteroids (NEO Surveyor, SphereX, maybe Roman eventually). I was allowed to open source it and I am planning on making it the basis of my PhD research:
https://github.com/dahlend/kete
It can predict the location of the entire catalog of known asteroids to generally within the uncertainty of our knowledge of the orbits. Its core is written in rust, with a python frontend.
Ever thought of making a presentation about this subject and putting it on YouTube? :-)
It sounds really impressive.
I've never really dabbled in youtube. I have several projects/papers I am working on using this code, I have thought about writing some blog posts as I publish those. But a PhD is going to be a major time sink, we will see what happens.
A tree cutting tool.
Take photos of the tree from 6 different angles, feed into a 3D model generator, erode the model and generate a 3D graph representation of the tree.
The tool suggests which cuts to make and where, given a restricted fall path (e.g. constrained by a neighbors yard on one side).
I create the fallen branches in their final state along the fall plane, and create individual correction vectors mapping them back to their original state, but in an order that does not intersect other branch vectors.
The idea came to me as a particularly difficult tree needed to come down in my friends yard, and we spent hours planning it out. I've already gotten some interest from the tree-surgeon community, I just need to appify it.
Second rendition will treat the problem more as a physics one than a graph one, with some energy-minimisation methods for solving.
Funny, one of mine also involves trees -- but is mostly outdoor cleanup. The kind that involves decades' worth of it, thanks to what I'll just say is a lot of maintenance that wasn't done over a long time. There's an extensive amount of brush, leaves, etc of varying ages that could maybe be shredded up into something useful, invasive vines I'm still trying to deal with, and more old trash than I've fully figured out how to properly dispose of.
It's turning into various DIY rabbit holes, actually, with the next one (outside of various related landscaping stuff) being to gut a basement.
Do consider the value of the wood in relation to your cuts. A well-placed cut not only guarantees safety but will also take the maximum board feet from the tree.
i work a lot with NVEL for this. one time even tried porting nvel to wasm for fun and client accessibility. we "virtually buck" trees which seems like could be applied to your proposed use case. if op wants to go down this path: https://github.com/FMSC-Measurements/VolumeLibrary/tree/77d4...
Seems insignificant. What are you optimizing for- an extra foot or two?
Yes, board feet is usually measured by the inch.
Aren't longer boards worth more per boardfoot too?
Yes, and the wider the more it costs per bf as well.
I have a couple products I make that require 12" widths, which means I pay a whole lot more per bf than < 10" widths at my hardwood supplier.
Yes, but most trees are plenty tall enough.
Then just make the cut as low to the ground as possible. You don’t need a lot of complex math for that.
No offense, but this comment is very reductionist. The problem isn’t nearly as simple as you’re making it out to be.
This is the kind of thing that makes me love HN. An idea I would never have thought of, with an immediately obvious use in multiple ways (fall path plus ideal lumber cutting?), probably very difficult, yet being tackled with one implementation already... and spoken of quite humbly.
That’s a great idea, but so much liability if the user is an amateur and follows steps incorrectly
Or perhaps follows the steps correctly.
I was imagining something like this for pruning fruit trees — something to help noobs like me see how to put pruning guidelines into practice on a real, overgrown tree. Good luck!
Where I live this could be very helpful becuase people is too, how to say it, maybe ignorant in safety and logic specs. Also could be usefull to know or estimate what tree are in a innminent or highr posibilities of fall with wind.
Happy to help!
How does the graph representation help you solve the problem?
I was mixing methods, sorry. My initial rendition for solving the cuts would initialise a somewhat sparse network from tree to ground, and solve for non-overlapping paths.
This became convoluted and I just opted for a far easier method of solving vector intersections.
Its also not perfect since I haven't factored in rotation origin very well, and I'm now pursuing a far simpler physics-based approach
Working on a browser extension to make it easier to find content on YouTube that fits your interests.
I watch a lot of YouTube videos and have found it very annoying that YouTube latches onto one or two topics that you've watched and only recommends that type of content over and over again. Even if you use their "Not Interested" tool, not a whole lot changes in your recommendations.
At the end of last year I launched Relevant - a crowdsourcing website where users can categorize the channels they watch into a defined hierarchy of categories ranging from broad topics like "Science" and "Gaming" to more specific ones like "Phone Reviews" or "Speedrunning".
Although I've had good feedback on the website, engagement has been relatively low and I think that's because it's a big ask to have someone navigate to the website to find the content. This year I decided that I'd bring the content to them by making a Chrome extension that lets users interact with Relevant directly from within YouTube.
It's still a work in progress but I'd love to get a first version out within a month or so to start spreading the idea and gathering feedback. If this is of any interest to the people here on HN then please let me know what you'd like to see most on your feeds.

I’m working on Popgot (https://popgot.com), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials.
On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging peanut butter with BPA by checking every photograph of the plastic or avoiding palm oil by reading the nutrition facts) or brand lists (e.g., only showing WSAVA-compliant dog foods). Still reviewing results manually to catch bad extractions.
Started this to replace a spreadsheet I was keeping for bulk purchases. Slowly adding more automation like alerting on price drops or restocking when under a threshold.
I like this idea a lot -- feels like there's a lot of room to grow here. Do you have any sort of historical price tracking/alerting?
And/or also curious if there is a way to enter in a list of items I want and for it to calculate which store - in aggregate - is the cheapest.
For instance, people often tell me Costco is much cheaper than alternatives, and for me to compare I have to compile my shopping cart in multiple stores to compare.
Cool! I hope it's coming to Japan (I live) near future.
https://github.com/colibri-hq/colibri/
Colibri—a self-hostable web application to manage your (and your family's) ebook library, intended as a companion to Calibre. I want it to be a friendly, simple, capable, opinionated app to review your books, add metadata to them, get them onto your reader, share them with family and (few) friends, create a public shelf for bragging, connect with Goodreads etc., and exchange comments and reviews on books.
This is explicitly not intended to ever be monetised, and I enjoy all the implications that has on the design. Colibri is as much a tool I personally want to use, as it is a study in small-audience user interfaces, and the quest to build the perfect book catalog schema.
I'm looking for fellow book-loving people to work on Colibri, to create the best personal digital library possible. If you're interested, feel free to reach out via email (in bio), or on GitHub.
This is super interesting. Where do you store the ebooks and the metadata?
A fan chiming in. I'm really happy someone someone is tackling this and it's looking good. One thing: can we get a demo instance just for initial snooping? A screenshot or two is fine but to get a feel for features it would be nice to have something (even heavily limited) we can just interact with?
That's the first thing I'm going to do as soon as it's possible! I recently refactored the code base to a monorepo, and still need to make some adjustments so it'll run stable again. Stay tuned :)
Ooh, this looks fantastic. I'd love to help, but I'm spending almost all of my off-work hours looking for jobs right now. Maybe I'll find a good one sooner rather than later...
Working on Taskade (https://www.taskade.com), building the execution layer for AI collaboration.
Taskade started as a real-time workspace for teams to organize projects and ideas. It's evolved into something bigger — a platform where humans and AI work side by side.
We’re moving past simple chatbots into real agentic workflows, where teams can generate structured task lists, mind maps, and tables, train custom AI agents with dynamic knowledge, and automate work from start to finish.
Today, Taskade is built around three core pillars: Projects, Agents, and Automation. It’s like giving your team a second brain that can think, plan, and get work done across projects, automations, and real-time collaboration. If you’re interested in the future of human-AI collaboration, take a look!

I'm still tinkering on my multiplayer game server framework when not grinding away at my day job.
The idea is essentially: An Erlang-based control plane, supporting ENet and WebSocket connection modes, with Protobuf for messages. Erlang has an excellent concurrency story, and I think it's a great fit for game servers. I've wrapped up a bunch of this work into behaviors on the Erlang side, such that developers can target the "gen_zone" behavior (for instance) to implement a tick-based game server. I'd like to expand that into other types of games, such as turn-based games.
I've also got a Godot plugin for generating a client library based on your protobuf schema. The plugin handles session stuff, exposes functions for client-to-server messages, and emits signals for server-to-client messages.
These days I'm working on integrating Luerl (Lua in Erlang) and Love2D support. I want to be able to take advantage of Erlang on the back-end while writing the majority of game logic in Lua. Further down the road I want to explore hot reloading parts of the Lua game state on the client/server, perhaps with an in-game editor, to develop the game "inside-out", in a way.
https://mysukari.com - A Diabetes management platform
I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and started working on My Sukari as a platform of free tools for diabetics.
I mostly get time to work on it on the weekends, so it's not yet ready for public use, but I've fully fleshed out one of the main features: Sugar Dashboard - A dashboard that visualises your Glucose data and helps you easier analyse it.
To help with demos, I've shared my Sugar Dashboard here: https://mysukari.com/tools/sugar-dashboard/peter
I'm really passionate about this and getting as much free, practical tools in the hands of patients (it honestly shouldn't be this hard to manage a disease)
Is this just for Type 1 or would type 2 work well also? Seems like it would?
All types. The sugar dashboard allows import of data from different glucose apps, so its goal is to allow you visualize and analyze your data. I hope to integrate with cgms directly if I get some that allow it, and also source from Health connect. Sharing with specific people eg doctor is also a big ask that I'm working on. The other WIP tools will be fore general health, not just diabetes, like carb counting from a photo via AI
Also recently diagnosed and just open sourced how I'm using AI to count carbs + get insulin doses [1]. Biggest issues I've seen to starting a legit business is not having sanctioned access to real-time blood sugar values (the APIs are all one hour behind), and dealing with the FDA. Love the idea of more tech-enabled diabetes management, good luck!
[1] https://github.com/kennedyjustin/BolusGPT
Love this! Thank you for sharing! My backend is also in Go so this is a godsend. Will see how I can incorporate and let you know if I do!
> not having sanctioned access to real-time blood sugar values (the APIs are all one hour behind)
Ah, I didn't know this. One of the prospective tools I had in mind was real time alerting in case of drastic drops eg ping doctor or relative. I think will have to be limited to the apps/tools that do support realtime.
Technically there is unsanctioned access (someone reverse engineered the real-time APIs [1] which I ported to Go). I think the FDA does not want easy access to real-time values so that folks can't easily recommend insulin dosing without oversight. I am personally of the opinion that it is our right to have programmatic access to the real-time data and do with it what we please.
Would love to get in touch to hear more about your long-term vision for the project!
[1] https://github.com/gagebenne/pydexcom
That's so cool! Nice work!! Are you happy to share how you built and host it? How long has it taken you to get it to this point?
Thanks! I started out with a Nextjs full stack on Vercel, with db on Turso but ended up with a React frontend (next on vercel) and Go backend (selfhosted on vps).
Decided to port the backend to Go + postgres (on a Hetzner VPS), and retain the frontend on Nextjs - A lighter weight client, moving most of the compute to the backend API. Few reasons for the port: I've had a lot more success/stability with Go backends, Turso pulled multi-tenant dbs which is what I mostly wanted them for, Nextjs is getting too hard for me.
Go backend is just the std lib (1.22+ server with the nice routing) - I mostly write all the lines in this
Frontend is textbook modern react: React19,next15,tailwind4 - AI mostly writes the code in the frontend (Cursor + Cline + sequentialthinking + context7 + my own custom "memory bank" process of breaking down tasks). AI is really, really good at this. I wrote this https://image-assets.etelej.com/ in literally 2 days 2 weekends ago with less than 10% of code being mine (mostly infra + hono APIs)
I launched Foqos here a few months back: https://github.com/awaseem/foqos and just working on the feedback. Since then added QR codes, breaks, ability to block apps manually and even a mini redesign. It’s been a ton of fun so far!
The first ever SQL debugger – runs & visualizes your query step-by-step, every clause, condition, expression, incl. GROUP BY, aggregates / windows, DISTINCT (ON), subqueries (even correlated ones!), CTEs, you name it.
You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.
Entirely offline & no usage of AI. Free in-browser version (using PGLite WASM), paid desktop version.
No website yet, here's a 5 minute showcase (skip to middle): https://www.loom.com/share/c03b57fa61fc4c509b1e2134e53b70dd
This would be incredible to understand why some queries execute slow; most of the time it's one of the steps in between that takes 99% of the execution time at our company. Do you record the time each step takes?
This is awesome! I’m work with a team of analysts and data engineers who own a pretty big snowflake data warehouse. We write a ton of dbt models and have a range of sql skill levels on the team. This would be the perfect way to allow more junior devs to build their skills quickly and support more complex models.
I would recommend you target data warehouses like snowflake and bigquery where the query complexity and thus value prop for a tool like this is potentially much higher.
Thank you, nice to get some idea validation from folks in the industry. For sure data warehouses are the top priority on my TODO list, I picked PG first because that's what I'm familiar with.
I can ping you via email when the debugger is ready, if you're interested. My email is in my profile
Was thinking today... not a debugger but even a SQL progess bar, so I know that my add column will take say 7 hours in advance.
Cool! We're dealing with many complex CTEs and costly queries. Would be useful to have those visualized one by one.
What database are you using? I'd be happy to hear about your usecases and hopefully help you, shoot me an email (in profile)
Nice one!
This seems like it could be extremely useful.
Thanks! Would you mind sharing what would be your use cases?
At my job, all of our business logic (4 KLOC of network topology algorithms) is written in a niche query language, which we have been migrating to PostgreSQL. When an inconsistency/error is found, tracking it can take days, manually commenting out parts of query and looking at the results.
Am not the person you asked, but feel that it could have good value for education and learning as well, besides debugging.
Is this postgres only? What an interesting idea!
For now, yes, but I'll start working on adding support for all other DBs (especially OLAP) as soon as possible. The geberal approach is the same, I just have to handle all the edge cases of the SQL dialects
I am working on the sunflower plant density estimation problem. The goal is to be able to estimate the germination rate as early as possible. Farmers benefit from such information, because:
- there are lots of expenses still to be made (fertilizer, pesticide, salaries), which may not be worth it if germination is under certain threshold
- if detected early, there is still time to plant another grain or to fill up the missing plants (requires precision seeders and seeding maps)
- is a very good proxy for yield estimation (farmers often trade futures even before they have harvested)
For the purpose I have created a dataset (a collaboration between my employer and Sofia University) and published it in order to enable scientific collaboration with other interested parties. Still working on the dataset annotations.

Interesting, I'm also involved in a project to do yield prediction, but with a ground-vehicle with camera's on top to drive between strawberry and blueberry plants.
Yield prediction is huge indeed, because overshooting your prediction means seller stuff for a lower price. Undershooting means paying for someone's product to make up for the difference. Probably there's quite a bit of matchmaking in between those under and overshooters and someone making a good buck out of that too.
Very cool, what type of parameters are within your control if detected early?
So many cool technical projects here. But I am doing something completely different - masonry. Repairing walls in 3 rooms. It includes reinstalling dozens of falling off bricks, installing 30 or so power outlets, replacing old windows with bigger modern ones, fixing openings for the doors and plastering everything afterwards. On one hand it’s interesting, because it’s very different from the dayjob. But doing it by myself pays my newish car in cash immediately. However I wouldn’t do it for money somewhere else, it’s really really hard work.
Instead of masonry I would like to work on time of flight cameras. But the day has only 24 hours :-(
I launched my web-based notepad calculator, https://numpad.io/, a few years ago.
Right now I'm working on a version 2 that has user accounts, multiple documents, markdown support, and document exports. Everything is local-first and it uses CRDTs to sync documents.
It looks like this: https://i.imgur.com/Plk1DQ4.png the calculator is mostly the same for now, with a few improvements. It's unstable right now, so I don't want to publicise the dev url, but if you'd like to become a beta tester email me at contact@numpad.io
That 'per' and 'to' syntax you got there is chefs kiss.
Thanks! Though I can't really take credit for it, Soulver did it before me.
Creating a modern development environment for win98. Currently I’m working on a git client. I have no patience for learning C. So backporting git is not an option. I also don’t want to use cygwin. So I’m using a server to expose git as http endpoints and coding a git client in php to use in msdos. I have Vim 7.3 and and gnu coreutils working in msdos already. So soon I will have a very nice dev environment. I want to create a one click installer which gives you xampp, vim and then all the tooling I’ve created. I’m also interested in creating SPA that works in IE5.5. But I’ll do that when my tooling is ready.
A Prolog TUI library that sticks to relational/logical programming, is conceptually simple, complete, and performant. Only requires some core ansi features that exist or are easily implemented in most Prologs. Currently have stuff like nested scrollable areas, toggles, frames, buttons, layouts working.
Also, a visual programming language implemented as a PICO-8 script, where the "programming" is done fully in the sprite editor.
It tried out vibe coding this weekend. I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.
I hit an OpenSearch bug this week where you can't get any browser based requests to work. Its due to zstd becoming a standard part of Accept-Encoding and OpenSearch not correctly supporting it so I wanted to install a browser plugin that modified the browser HTTP request headers to my servers.
I don't know about everyone else but I love that browser plugins are possible but I hate having to find them. Its mostly due to never knowing if you can trust a plugin and even if you find one, you have to worry about it being bought out in the future. With vibe coding I was able to build a browser extension in 45 minutes that had more features than I originally planned for.
I spend more time documenting the experience than building which is wild. If you are interesting you can look at the README in https://github.com/mattheimer/vibe-headers
But I left the experience with two thoughts.
Even seasoned developers will be using vibe coding in the future.
I think in the near future the browser plugin market will partially collapse because eventually browsers will build extensions themselves on the fly using natural language.
In my experience, "vibe coding" can produce a rich prototype very fast.
Then as scope expands you're left with something that is difficult to extend because its impossible to keep everything in the LLM context. Both because of context limits and because of input fatigue in terms of communicating the context.
At this point you can do a critical analysis of what you have and design a more rigorous specification.
I don't disagree but context limits are expanding rapidly. Gemini 2.5 Pro which was used here has a 1 million token context window with 2 million coming soon. Cost will be a concern but context size limits will not.
Totally agree, I mentioned it in another comment but Gemini was a game changer for allowing me to increase the size of the project I can feasibly have AI work on.
Only issue is Gemini's context window (I've seen my experience corroborated here on HN a couple times) isn't consistent. Maybe if 900k tokens are all of unique information, then it will be useful to 1 million, but I find if my prompt has 150k tokens of context or 50k, after 200k in the total context window response coherence and focus goes out the window.
I'd love some more innovation on increasing context size without blowing up RAM usage. Mistral small 2503 24B and Gemma 3 27B both fit into 24GB at Q4, but Mistral can only go up to about 32k and Gemma about 12k before all VRAM is exhausted, even with flash attention and KV cache quantization.
But my reading is that the parent wouldn't have tackled this at all without the vibe coding, and would have used an off-the-shelf extension. So in that case, it's a pure win, no?
Yeah I could have framed it better. I was responding to:
>I've been using AI to get smaller examples and ask questions and its been great but past attempts to have it do everything for me have produced code that still needed a lot of changes.
In my experience most things that aren't trivial do require a lot of work as the scope expands. I was responding more to that than him having success with completing the whole extension satisfactorily.
So there is no technical debts ?
That's a difficult question to answer because I don't know if I'll grow the extension in the future. Only time will tell.
After I completed the extension I did try on another model and despite me instructing it to generate a v3 manifest extension, the second attempt didn't start with declarativeNetRequest and used the older APIs until I made a refinement. And this isn't even a big project really where poor architecture would cause debt.
Vibe coding can lead to technical debt, especially if you don't have the skills to recognize that debt in the code being generated.
I have been working on http://phrasing.app - a language learning & acquisition tool for polyglots. I’ve been using it to study ~12 languages (5 on maintaince, 2 seriously studying, 5 casually “studying”) and it’s starting to feel really good. If anyone is learning/maintaining several languages, please reach out! I’m looking for beta testers in as many languages as possible (it supports 120+).
In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession
I have just created an account and tried to use the app; either I am dumb (at this hour), or the app has a very not intuitive UI :-)
I (think I) managed to create an expression, but: 1. it takes forever, I don't know what it's doing and it's still not done 2. I have no idea how to use it, onward 3. does not seem that I will be actually able to use it, as the app requires to be subscribed to use it...
Looking forward for a how to use manual / page + a real trial period. If the app requires a subscription with this UX experience, I will be gone :-)
I am the first to admit that the UI does not make sense to people who have not seen it in use. I have done some user onboarding sessions where you just “let them ask questions and click” and it goes terribly if it’s any consolation, I have never gotten that feedback after showing people how to use it (quite the opposite actually!)
Wrt to the expression, all expressions created today succeeded, so if you’re still seeing a progress bar let me know as that’s a bug. It’s possible something failed with the live updates, or it does take several minutes to create an expression (depending on servers, it can take up to 10 minutes at times, although the typical timing is 2-4 minutes depending on the expression)
If you click on any of the review methodologies, it will start reviewing any of your successful expression. From there, the experience should be a lot more explorer-friendly :)
What it’s doing is: analyzing the sentence, splitting it into phrases, aligning it across all languages, tagging all of the gender/case/tense/etc, researching pronunciation, generating audio, aligning the audio, prioritizing the words (across several axes), and generation explanations/dictionary for each individual word
Great job on the design. I like the idea here, but the app was unresponsive on Windows > Chrome to most clicks
The UI was a little unresponsive on mobile, and when I opened the "Media" page on desktop I got multiple block rendering errors. Opening the console reveals a syntax error (missing ] after element list) and some type errors.
Also, it looks like you have to get the subscription to use it in any way? It's hard to gauge whether it is for me or not if I have no way to trial it. I found the UI a bit confusing too, I was not sure what I was supposed to do after logging in. As another commentator mentioned, it's asking me to set a reference language but I see no way of configuring it.
Block rendering errors on the media page is new to me. I will look into it.
The reference language error should not be shown (I mean it’s not incorrect, but there is a “no expressions error” that should take precedence).
A video is coming :) I didn’t expect so much interest from a comment in this thread. If you get in touch, I can walk you through it personally, otherwise check back in a couple weeks and there will be a video overview.
Sounds good.
What languages do you support?
Learning Latvian through Anki flashcards, but it's not well supported by the main platforms, and there's not a huge amount of content out there for learning.
This alongside a couple of the usual suspects.
As a side note, on a Pixel 4a 5G (old phone , but functionally not ready for e-waste) the homepage bleeds all over. Some components into each other, others off screen. Might want to check that.
Oh no, the website is brand new, it should be working everywhere. I'll have to dig up an older android, I should have one somewhere.
Languages below, if you know their alpha 3 code. Currently having some issues with Thai and Zulu though, so they're temporarily disabled until I have time to fix them.
I have not ~tested~ verified it for Latvian, I would be curious to hear your thoughts. It has been working pretty well for Maltese, Albanian and Macedonian though, which should be lower resource than Latvian!
As mentioned elsewhere, the first time user experience is abysmal. If you reach out though we can hop on a call and get you set up - or in a few weeks I'll have a video done and up. In the meantime, you should be able to create an expression (in the nav bar for desktop and mobile) fairly intuitively.

EDIT: I have tested it for Latvian, I know it technically works. I however have not had any Latvian speakers review it's quality
Since you're in Amsterdam, I'm curious how well you think it performs for learning Dutch? I'm a native English speaker with a B2~ in Dutch and just looking to progress more. I've not used spaced repetition up to this point in my learning journey (almost 3 years).
It does really well, 95% of the time. The application was built to jump in at any levels - find a movie you want to watch, align the subtitles, see the most important words, create expressions with words you don't know, and the SRS should focus on the words most important to you.
For my Dutch (which was probably once a high B2, now probably a low B1) I only use the audio review when walking my dog or cooking. It plays the audio of the cards in a playlist, so I practice hearing and repeating them.
It's not so self serve at the moment, but if you get in touch I can get you up and running.
I was quite eager to check this out. As some polite feedback, a few things turned me off quite strongly:
1. I want to get confirmation that the language I want is covered (Hungarian). "120+" doesn't confirm it for me, as Hungarian seems fairly rare for language apps. Can we not just have a "search your language" field?
2. I need to see what the app actually looks like, how it proposes it'll teach me.
I'm one of the eager-to-pay people, because Duolingo is frankly dogshit (ok. Mostly polite) at teaching languages (doubly so ones that it doesn't care about like Hungarian). But I'm so suspicious of language apps, due to being burnt a dozen times.
Thanks for the feedback! I agree with you completely.
1. I just started the marketing website a few weeks ago, and if you can believe it, I didn't readily have that information. One of my tasks last week was to compile a list of languages that could work, write some tests for all of the languages, and get a list of supported languages. I have that list now, I just need to put it on the marketing page.
2. As mentioned in other comments, I'm working on a video. I'm preferring to fix glaring issues before making the video, although at this point I'm verrrrrrry close. I have started scripting it, but it takes a lot of time to make a good video (1-2 full days if I don't want to edit it).
Your feedback is completely valid, and they're both reasons why I'm not really marketing the product yet. This thread seemed like a good middle ground though as having some people using all the languages would be really helpful. Also, I've genuinely been loving using it and want to share.
It's just me working on it, so these things are coming, but everything takes a while! Hopefully these didn't sour you on the project permanently :)
EDIT: And yes, it supports Hungarian :)
Thanks for addressing, really!
Nope, not soured. And don't worry, I totally get that things take a bunch of effort and time (doubly so as a solo project). I'll give it a re-look in a little while :)
And fwiw, I've added the languages to the marketing page now in the FAQ section. I'll add a more prominent section in the coming weeks!
i signed up and tried to use it. The UI is very confusing. i couldn't find the place to setup what language i want to learn and what language i know (for translation). It is best if you can have a video or images documenting how to use it.
Agreed. I’m getting close to a video to put on the landing page, probably some time next week.
The first time user experience is really bad, but the app itself makes a lot of sense once you see it in action. Feel free to get in touch with me (there are several methods listed when you log in) and I can give you a personal introduction!
If not then check back in a few weeks for a cool video :)
Yes, please. I've been looking for something like this. Lately I've been just casually going into another language with ChatGPT and asking it to correct me. I do I like some of the old languages, things like Aramaic, which just have a different feel.
I signed up, but now it's asking me for a "reference language" (which is a little ironic because it tells me this in English lol). I guess I'll play with this later.
Start by creating some expressions ("create" in the nav bar) and you should be able to play around with it. If you want to learn more, please get in touch. As mentioned elsewhere, I'll be adding a video tutorial soon (probably not this week, but sometime next week if all goes well).
Would love to get feedback on the old languages! It's been really good for the minority languages I'm learning
Would be great to be able to login via Google or Facebook. Creating an account is cumbersome on mobile.
"...are we still doing phrasing?"
So much of this stemmed from me wanted to learn French & Italian by watching archer :D
A note taking app - I know, I know, been done a billion times. But really, no software I’ve found works the way I want it to, so I’m just trying to write my own, starting with a front-end agnostic core and a TUI.
If it strikes a chord with anyone, I’d love to collaborate! The concept is centered around organization bubbling up naturally from dumping info in with tags, and “typing” your tags so that when you go to a tag’s page, the layout is customized based on what it is - a project, person, etc. A project could have all relevant tasks and notes listed, whereas a person might have name, contact info, etc.
https://github.com/weakphish/yapper
Expanding some - the tags concept is similar to AnyType[0] types, but the rest of the software I’m writing is more oriented towards dump-first, tag, and let it sort itself out, whereas AnyType requires careful management and configuration of the workspace.

Myself.
Been a freelance dev for years, now going on "sabbatical" (love that word) imminently. Just moved to reduced hours, still in the transition and unwinding phase.
Planning to do a lot of learning, self-improvement, and projects. Tech-related and not. Preparing for the next volume (not chapter) of life. Refactoring, if you like, among other things.
I'm excited.
Will you write a bit about it? I find this sort of move really interesting. I'd be curious to see what you've learned by the end of that sabbatical.
Depending on how long you're planning on sabbatical-ing, you might consider applying to the Recurse Center [1]. It's basically a (free) 6- or 12-week self-directed learning program that you do with others.
I had done a half batch last year and really enjoyed the experience.
[1] https://recurse.com
I am in a similar stage.
In brief:
25 years of experience including FAANG. Recently got divorced (complex litigations, fought hard, very satisfied with the outcome).
Now rethinking myself. Want to do something useful for humankind in the rest of my life. Having big ideas for the future. Trying some research-focussed 'side' projects. Considering writing a book. Learning new things. So on.
This sounds very cool! Do you have any travel planned? A move within country to more of a "reset" locale? :)
I like the concept of "refactoring" one's life.
AI bookkeeping for solopreneurs.
As a freelance web dev who also has an Airbnb side hustle, I got tired of expensive bookkeeping for a few transactions per month. I tried DIY, but my time is worth more than that.
Most importantly, both pros and DIY got subtle things wrong and caused me to miss out on thousands of dollars in deductions and credits.
So I’m making an AI bookkeeping chatbot that will handle all that for me. The aim is full automation while surfacing tax deduction and credit opportunities throughout the year. Like wouldn’t it be awesome to just have the research and tax credit or do home office deductions with zero effort?
At the end of the year, Kumbara puts together a series of financial reports that you plug into your tax software or hand to your CPA.
Working hand-in-hand with CPAs and some platform partners on this. Would love to hear from other solopreneurs or engineers who want to help build the future of financial freedom.

I still have no idea if it's a good idea or a bad idea but it's been fun to think through.
I hacked my old kindle and turned it into a eink dashboard for my daughter’s school! Now planning to enahace it a bit further and make it easy to customise.
Here’s a a detailed write up of the process: https://samkhawase.com/blog/hacking-kindle/
Genuinely brings a smile to my face. And such a nice exposure for the kid.
Thank you for the kind words. I’m trying to get back into writing and such feedback means a lot to me.
Love it! Nice work
Creating stealth group in a huge Fortune 500 company with the blessing of my immediate boss but no other higher-ups. Trying to productize critical consulting tool sets in the utility industry so we can stop repeating ourselves for the 100th consulting engagement.
Yes, customer is a special snowflake but they still need 90% or whatever every other client in this industry needs.
Feeling increasingly like this is a fools errand.
Even though we've proved this out with tool sets strung together with duct tape and safety pins, and are therefore the most profitable group within our department, we still need to be 100% billable.
It's only because we're the most profitable group that we can pretend we're all billable while I work with two other people to bootstrap this crazy project
Edit: anyone hiring? Just found out my boss is quitting.
Oof. This post started so good and then got progressively more sad until the edit nailed it home. I hope your story continues and works out as a huge win, either as a new, good boss, you getting to openly lead this kind of thing, someone reading this and poaching/sponsoring you, or maybe even you working on this under your own name.
Good luck and we're rooting for you!
Thank you for the enthusiasm!
It was not intentional but my post really does read like a little story vignette that ends with a gut punch.
Not looking for sympathy so much as fellow appreciators of irony and schadenfreude but here's another kicker.
I pitched this idea to my previous company and was told there was no appetite for it. Just saw on my old company's blog that they released a "digital transformation in a box" program for mid-market clients in this space which is 90% of what I pitched to them. Bad and hilarious timing all around.
Good lord, how many times are you going to get punched in the gut today?
Very interesting. Maybe we can chat and explore? DM me on my X.com - it's on my HN about page - copy-paste the HN link here for context :)
Last year I bought a broken jukebox. I wanted to convert it to be powered by a raspberry pi. I wanted it to work like a traditional jukebox where you used the buttons to input the song number. While there are a few existing projects to convert Jukeboxes to run from raspberry pi, most of them used a touch screen or didn't work well on RP5 which is what I had or the current version of raspberry pi os.
So despite not being a programmer, barely knowing a little javascript, and nothing about python, linux, or gtk, I was able to use AI to muddle my way through to creating a program that takes the input from a numpad, looks up the song from a list, sends it to mpd, and posts a picture from the album art embedded in the music file. https://github.com/jccalhoun/mpcButtonJukebox
An eBook sever on raspberry pi running nodejs. I had a lot of issues with iCloud not being able to download my books, plus my entire library is almost 1 GB. So, my solution is to serve a list of PDFs over node and allow download of a specific page range.
Reverse typesetting: reflowing page layouts where you don't have knowledge of the typesetting structure, i.e. a scanned physical book or PDF paper. Naive rules-based heuristics based on the dimensions of bounding boxes and gaps. Point is to reflow things for resizing to eink readers. (Specifically the size that fits in my pocket which I carry around. User #1 is me). Building in Common Lisp and targeting an Emacs mode for interactive execution with manual feedback.
i don’t quite understand, what makes it reverse typesetting?
my understanding is your typesetting books for responsive eink readers.
You're inferring the structure of the document from the printed result. If typesetting takes a set of layout directives and outputs a page, this is taking a finished page and guessing what layout directives could create it. Then you can take that inferred structure and reflow the page in a new layout.
so like ocr but not recognizing characters and words but recognizing the layouted structure and transforming it into content markup and layout markup?
That's a way to view it!
The reason I'm not falling back on OCR is because the general case is full of things, like math equations and inset graphics/diagrams, that can't be OCR'd. The only robust way to deal with those is to treat them as graphical atoms: "this bounding box can be moved around, but should not be split up into pieces".
PodSnacks (https://podsnacks.org) — Personalized AI summaries of top podcasts, delivered to your inbox.
I've been building PodSnacks because I found it overwhelming to keep up with podcasts across tech, business, and science. PodSnacks uses LLMs to summarize the most popular episodes from shows like Lex Fridman, Acquired, All-In, Invest Like the Best, and more.
You choose your favorite shows, and we email you short, high-signal summaries — no audio to skim through, no endless backlog guilt.
So far:
126K+ episode summaries generated 92K+ hours of podcasts processed 48–50% open rates 2,900+ early users
Still iterating and adding features like bundling by theme, language translations, and audio feeds.
If you're the kind of person who wants more inputs without more noise — would love for you to check it out.
Always open to feedback from HN!
What are the costs like, for such a service? You have to spend for transcribing (even if you ran something like Whisper) and pay for APIs to summarize, correct?
I'm also interested in this. :)
any way to expose api access for the keyword search feature? would be cool to build this into some topic summaries delivered via email I'm building for my team
I’d prefer summaries of my YouTube subscriptions, where I can also add my own “summary template”
In currently have a prompt for it that works for me, based on the transcripts.
Problem: too much duplicate information in any type of publication and too much fluff
Problem2: YouTube/transcriptions
Probably wouldn’t pay for such a service, but would be very happy using it. Perhaps some channel promo / email based ads for discovery or recommendations.
Interesting. Once signed in, how do I search for podcasts? Discover is not showing a search field, unlike https://www.podsnacks.org/newsletter/podcasts
Edit: Ok, I found the search function in the hamburger menu. A bit unintuitive.
That's awesome! I'm really not a podcast person, but a lot of good content is available primarily through podcasts. Hope that can help with it.
Just signed up! Do you use different AI prompts for each podcast based on the specialty or a single prompt?

I am working on a super mario land re-implementation for game boy using C. It's made with the GBDK toolkit so the ROM can be run on a gameboy. Currently the scrolling and background collision has been implemented, I am working on drawing the enemies... their is still a long way to go. As for why I am doing this is nostalgia and fulfilled a childhood dream repo at https://github.com/odrevet/marioland-gbdk/
I remember SML fondly, best of luck.
Love it, good luck with the project!
I'm building a simple web-based drawing app for home sewing patterns. It's a little bit CAD and a little bit sketching tool. Born of my desire for easier and 100x cheaper home drafting tools. The app is still quite early (adding Bezier tools today) and the core workflow is not functional: of draft, lay out, print, repeat, only draft is working. But one step at a time! https://github.com/twaldorf/flatland-client
I'm in the midst of a tectonic career shift, from being laid off from a position and place I loved, to another gig while I keep looking for another unicorn role like before.
So most of my project work is home-based, after years of being able to chase (and execute) dreams at work.
On the technology front, I'm finally investing in a proper network core for home. WiFi 7 AP, 2.5Gig core, PoE everywhere, zone-based firewall. Still mapping out DHCP scopes and VLANs, but once that's done it'll be moving on to proper IoT and Home Assistant build-outs to prepare for the Unfolded Circle 3 later this summer. Also looking to redo my two N100 hypervisors off Proxmox and back to RHEL + Cockpit, or some other Linux + KVM implementation; from there, it's all about Kubernetes, Ansible, and Terraform. Really just a lot of oft-postponed side projects because I had amazing fulfillment at work, that I suddenly have ample time for now.
Outside of the tech stuff, I'm still trying to get some decent photos of two local birds of prey that have been hunting in my neighborhood. They seemingly spite me by only showing themselves when I don't have my camera with me, but dangit, I will photograph them.
On the writing front, I've got a few topics jostling around in drafts: speculating on potential futures of LLMs, the internet as a psychohazard, and a series of "fundamentals" to try and teach my non-techie circles more about how computers and the internet work, so they can do some modest self-hosting and get off centralized services. I'll likely dovetail some of them with my own home projects, writing them alongside the documentation as I make progress.
> This weekend I’m working on mobile app that allows you to upload photos and it turns everything into a stitched anime (ghibli or not) with movements and eventually sound and script. Great to make mini animes from your day or travels or anything.
I vibe coded the above including everything: code, design, logos. Just did it solo. It has all error handling, video generation notifications (it takes a while) and credit system. I myself can't believe it's been done in a month with AI. It's already in closed beta in iOS and android app stores. Let me know if you want to try it out before public release.
My quoted comment above was 28 days ago. This is working on this part time and with a family.
EDIT: Added context.
A pentagonal geospatial indexing system: https://a5geo.org/
If you’ve used H3 or S2 it should be familiar, the major difference (apart from the fact it uses pentagons) is that the cell areas are practically uniform, whereas alternative systems have a variance of around 2 between the largest and smallest cells, making them less useful for aggregation. The site has many visual demos, e.g. https://a5geo.org/examples/area
The code is open source: https://github.com/felixpalmer/a5
Wow, that's a really fascinating problem to work on. I work in mapping but haven't actually come across this field of what you call DGGS's.
Is it essential that the cells be the same shape?
Also where does the name "A5" come from exactly? I get that 5 is because it has five sides, but why A?
The cells being the same shape is useful in some use cases and irrelevant in others. For example, see the Airbnb demo: https://a5geo.org/examples/airbnb. The H3 tiles are very different sizes in the two cities, and make it appear that there is a much higher density of listings in Malta, even though that is not the case.
However the symmetry of H3’s hexagonal cells lends itself well to flow analysis, or routing - which is no surprise as it was developed at Uber.
As for the name, it follows the convention of S2 and H3, which come from group theory and refer (loosely) to the symmetry groups of the various systems
Is it based upon repeated subdivision of an icosahedron?
No, it is based on applying a lattice onto the faces of a dodecahedron (technically a pentakis dodecahedron). Take a look at https://a5geo.org/examples/teohedron-dodecahedron and other examples on the website.
H3 is based on a dodecahedron it is it the reason the cell areas range so much, the same is true of S2 - but this is based on a cube.

This is one of my long-standing passion projects, a simple web-based music sequencer built to have a very low barrier to entry.
I am very interested in web based music creation, have you seen web-synth on github? https://github.com/Ameobea/web-synth
Looks good! I think adding timing grid would be cool, ala 1/4, 1/16 etc
I find tracking movies and series I have watched with my partner an impossible task. Spreadsheets are too fiddly for my partner, and I want to look up what is next on my phone so I have turned to Airtable and n8n for automation.
input a relevant url, it will decide if it IMDB or Youtube or a list. using an llm, it will attempt to extract the movies or series from the list and find the relevant IMDB link.
Then I have a masonry view of movies & series I have and have not watched, sortable by tags that I can rate and add notes to.
I’m working on SimpleeFood, a simple self hosted recipe app.
https://github.com/abhchand/simplee-food
I found most of the offerings out there to be too bloated. Recipes are a simple thing - you want to store them, search them, and view them easily.
It has a full screen viewing mode for easy cooking with your tablet or phone.
I've always been into MUDs since the mid-90s and every now and then I get this idea to write one from scratch (again) and I get pretty far and then I lose interest.
The new one is browser based.
The mud engine runs in a web worker and takes advantage of some of the modern web tricks to do stuff. For instance, data files (think: area files that don't change often) can be stored remotely and then cached with a service worker. This allows the MUD to run offline. But that's only fun if you're playing solo.
IO between the UI and worker is handled by message passing.
Multiplayer is handled by the MUD opening an outbound connection (probably websocket) to a connection collector host. Other players would then connect to that host and have their IO routed appropriately. The host can even be smarter: it could be a specialized Discord client, allowing users to play from there. Firebase may also be involved. I don't know.
The important bit is that this is still basically message passing, so the engine won't need to know the difference between the local user and a remote user.
The MUD database would be an IndexedDB. Probably. I haven't thought as much about that yet.
I am sure all of this is theoretically possible, at least.
YES! Another MUD programmer! I started writing one in Meteor about eleven years ago. I don't even know if Meteor's still a thing anymore... I've had a few projects in Rust that were mixtures of roguelike and MUD models, conceptually. I usually got aggravated with the models I created, though.
I really like your multiplayer idea. That sounds really clean and flexible.
IndexedDB seems really cool. Never really worked with it but seems like a good option for you.
Working on a database compatibility tool. So your app works on SQL Server 2022 on-prem, but does it work on Azure SQL DB, AWS RDS, GCP CloudSQL, etc?
These cloud flavours have a compatible SQL dialect, but it's often details like missing features (CDC and Auditing on RDS are good examples) or differences in system objects that make it difficult to support your app on these platforms.
I capture all sql statements, run them through multiple SQL parsers to find all the system objects your app is using (tables, functions, stored procedures, etc). I then check them all against a catalog I have built of all system objects for every version of SQL Server on every platform.
I then give a report to see which platforms your app will work on, which ones it wont work on and which system objects are the problem.
Other database engines will be added once I get it working end to end (almost there).
I just put live a daily logic puzzle, Clues by Sam. I've been working on it for a while now, mainly on the level generator. It was tricky to generate levels that are solvable using logic (no guessing needed), and also fun to solve (no crazy long deduction chains, but also not just obvious things). I'm sure the implementation still has some quirks on some devices, so would love to hear if you encounter issues!
https://cluesbysam.com
I really enjoy this! I like Murdle, too. I was very interested in a sort of quest generation system that would use similar concepts to generate RPG quests, basically constraint solving I suppose.
Thank you! This was definitely inspired by Murdle, so glad to hear it's finding the right audience. And yes, constraint solving is definitely at the heart of the generator. And you mentioning using it for RPG quests sets my mind racing...
Highly enjoyable (after I finally read the definitions of "neighbor" and "to the right/left")! Did you write a program that can automatically generate these?? I'll definitely try this again. Note, the emoji graphic in "share" might be buggy? I'm seeing one green checkmark, one green square, and four red squares..
Thank you so much for trying out the game and taking the time to write the feedback!
I did! That was the main workload of this project, and is still ongoing. I have ideas for improvements, and I also have to fix some sentences manually sometimes. But it's getting there.
The sharing shows a kind of "health bar". Every time you make an illogical guess, it reduces one. Running out of "health" doesn't prevent you from completing the puzzle, but it does show up in your share. Based on this, you made 4 "illogical" guesses. If you didn't, then there's a bug. But feels like I should anyways clarify this, if it wasn't clear to you. Thanks again!
This is great, but the need for a long glossary of terms is a sign that you might want to keep tuning language/word-choice.
As you've seen in replies here already, many term choices you've made have enough variety in how they're conventionally used that people incorrectly assume they know what it means only to see the "nope!" popup when they try to apply it. That frustration is going to spoil first impressions of what actually seems to be a really great puzzle system, which is a shame. The more you can reduce that experience, the less likely you'll be to prematurely burn off players.
A good measure for getting it right would be that you don't even need a glossary at all, or that you can get it so condensed that you can make it more prominent without becoming distracting.
Alternately, you could maybe use symbols instead of words to represent your rules, as more players would intuit that they should learn the symbols before making (wrong) assumptions.
This is great feedback, and I think you're spot on. It's been really challenging to find wording that is brief enough, but also specific enough. I hope it's something I can improve in the future as I keep exploring new ways of giving hints. The idea of using symbols is interesting, hadn't considered that!
frustrating. i eventually just clicked every single one, and keep getting the "This choice can't be made based on pure logic" message. maybe i'm just dumb...
You might be misinterpreting what "neighbor" means or what "to the left" means. There is always at least one choice that can be made logically. If the logical choice is, say, that Jess is innocent, and you say Jess is a criminal, the game won't let you do that choice. Maybe that's what happened to you?
I am working on an app for rhythm training for dancing. The first step is beat detection in music - here is my code for generating videos with beat counting: https://github.com/zby/beat_counter (vibe coding warning). Beat detection seems to work OK, downbeats are a bit more tricky and I have found not good solutions for further structuring of music (for dancing they usually count to 8 - that is two 4 beat measures - or 6 - two 3 beat measures for Waltz for example, I am not sure about 2/2 measures and other). Seeing all the LLMs generating music I thought there should also be LLMs interpreting music - but so far I have found no such model the available algos seem to be from a previous decade.
My current plan is to test the counting with people with good rhythm sense and once I find a good algo for beat detection I'll proceed with writing the app.
Very cool! Dancer here. Looking for something that counts music so I can do some choreopgraphy faster.
Working on designing and building an interface to properly integrate a modern phone with Toyota/Lexus infotainment systems from before 2010 (which are using the proprietary AVC-LAN protocol).
I've explored all existing commercially available solutions and none match my requirements/standards (high-quality audio codec/DAC, USB-PD, steering wheel controls, no splicing or cutting into the loom, no cutting up the dash, etc.).
After researching how the Toyota/Lexus infotainment systems work I found they are highly modular, and actually quite easy to produce custom modules for. The proprietary AVC-LAN protocol is well-understood, and actually makes it really easy to integrate with. The display are just NTSC composite, and touch events (in fact, all button presses, including steering wheel media controls) are emitted on the AVC-LAN bus.
An simple board with some interfacing logic, a DAC and an RPi nano should be all I need to allow good Bluetooth audio integration, and lossless audio via wired USB, both controllable from the steering wheel. You could do all sorts of fun things with the display (such as displaying vehicle status from ODB, lap timer, G-force meter etc.). If I use a RPi compute module then running Android Auto should be quite feasible.
It's just a hobby project though, I'll probably open-source everything. Not planning on commercializing it.
I'm already working on something like this and have a prototype board designed.
Here is my version 1.
https://youtu.be/pJjq_0hZEh4 https://youtu.be/drCtDADRJe8 https://youtu.be/jLCiIB6z968
Version 2 is being built around a CM4 IO board and will include my AVCLAN implementation, DAC, GPS and is intended to run AOSP Android. The board is fully designed already and I'm working on the custom Android build now.
Godspeed. I find it frustrating these systems don't follow some sort of international standard, still. I can't justify replacing the system in my 2016 Highlander just to get Android auto, but the Bluetooth system handles non-phone calls poorly and the album art database hasn't been updated for basically the entire life of the vehicle. I don't like having to rely on the manufacturer nor Google/Apple for connectivity basics.

Building an app that extracts key information from PDFs + highlights citations.
You provide a PDF and a JSON schema defining what to extract, and it returns the extracted values, the citations and their precise locations in the document.
This is especially valuable in workflows where verification of LLM extracted information is critical (e.g. legal and finance). It can handle complex layouts like multiple columns, tables and also scanned documents.
Planning to offer this both as an API and a self-hosted option for organizations with strict data privacy requirements.
Screenshot: https://superdocs.io/highlight.png
Feel free to get in touch for a demo.
I've been working on some structured OCR tools recently (in the context of reading resume pdfs and allowing much more useful search filters over them than our ATS system allows) and I've found Gemini with structured outputs capable of doing a fantastic job. I'm curious, do you have any rough pointers for how to do this self-hosted?
I am working on a curated database of proxy IP addresses frequently used by bots: https://deviceandbrowserinfo.com/product/proxies-ips
So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources.
I also made an open-source proxy IP block list based on the data: https://github.com/antoinevastel/avastel-bot-ips-lists
Wouldn’t this end up flagging a lot of residential IPs due to residential proxies?
The DB contains different types of proxies: - Residential - ISP - Data center
I don't include mobile proxies since they're heavily shared, so knowing that an IP address was used as a proxy at some point is basically useless.
Regarding your remark, indeed, there are several shared residential IPs, including IPs of legitimate users who may have a shady app that routes traffic through their device. That's why I don't recommend blocking using IP addresses as is. It's supposed to be more of a datapoint/signal to enrich your anti-fraud/anti-bot system. However, regarding the block list, I analyze the IPs on bigger time frames, the percentage of IPs in the range that were used as proxies, and generate a confidence score to indicate whether or not it is safe to block.
Sounds like pretty sophisticated filtering!
I’m working on a scraping project at the moment so looking at this too but from the other end. Super low volume though so pretty tame - emphasis on success rate more than throughput
I bought a 4G dongle for use as last resort if nothing else gets through. And also investigating ipv6
Using a 4G dongle makes it easier to hide in the crowd indeed. Since your traffic will go through heavily shared mobile IPs, probably with thousands of users behind them, anti-bot vendors won't/shouldn't block per IP, but per fingerprint/session cookie instead.
Ah hadn’t realised it’s the NAT. I thought it’s because the IPs are dynamic and rotate too much. Interesting.
Currently planning on doing a layered approach. Cloud IPs first etc.
Interesting challenge but also trying to be somewhat respectful about it since nobody likes aggressive bots
AI has taken over the hype in sales and go-to-market strategies. But for independents, solopreneurs, professionals, and many founders or CEOs, relationships and partnerships are still central.
I think sales will bifurcate: either fully automated self-sale, or fully relationship based. All of the major CRMs (customer relationship management) software are going all in on AI and sales automation.
I think relationship sales is going to see an increase in comparative advantage. I've always been a relationship seller but the current crop of CRMs are not designed for me. So I've built https://humancrm.io/ to scratch my own itch.
I'm working on a human-like AI opponent for VR table tennis. It's something I really want myself, love playing table tennis in VR, but with online play you get the latency issues, people that have adopted a playing style which basically hacks the game physics or other aspects, or people who are just plain rude. Playing against the AI is much nicer, but it's not varied or realistic enough such that when you actually play against real people you are ill prepared.
At a very early prototyping phase, but having a ton of fun. https://x.com/artofpongfu
Last month, I started playing around with code sandboxes and how LLMs might interface with them and wrote a little blog post about it [1]. I then took the code and vibe coded my way to a multi-tenant (untested!) sandboxing server that lets you run arbitrary Docker containers and provides a simple HTTP interface and UI. A cute, novel idea is that you can fork containers easily, as seen in the video in my repo:
https://github.com/ammmir/sandboxer
It may not be useful, but it's been fun, and I've honed my gut-level experience in Docker, Podman, Linux namespaces, Checkpoint/Restore, CRIU, and more. The ultimate goal is to hand each AI agent iteration a sandbox of its own (forked from the previous iteration), and have it build apps in private sandboxes. You'll be able to view intermediate progress as the app is being built (or failed rabbit holes), since each sandbox gets a unique URL automatically. Like, imagine if each commit of your git repo had its own URL to preview the app!

Resume builder
7 months ago, I was looking for a job and got frustrated with the current resume builders, so decided to build one exactly how I wanted a resume builder to be.
- Free (like really free).
- No signup, no login.
- Has AI features to improve text.
- Find jobs matching the resume.
https://resumeyay.com
Really neat app! A button that says "instantly" and actually does the thing instantly already makes this better than every alternative! ;)
Maybe just an idea I think would be worth charging for to offset costs on yourself: if you could get a few accounts on different recruiting software packs (BambooHR, smartrecruiters, etc) and then let users test their resume with different recruiting software's AI filtering tools, that could help a ton of people. You'd have to make a lot of different job descriptions/postings in each one, but you could probably craft them all generically enough to fit most careers.
Once that's going, maybe a pay-per-use fee to test your resume that gives the paying user a couple unique recruiting links to a few job postings, and then use playwright or something to capture screenshots of their profile in the backend(s).
Thank you! I appreciate the kind words.
I like your idea, but its hard to implement due to privacy concerns and could violate the ToS of these platforms (for sharing the account).
But I do have a feature in mind to do something similar. My plan is to always keep it free, with any feature, but I have to think of monetisation. Right now, it would be charging employers/job boards instead of job seekers. I've been there, the job search is stressful enough to add financial burdens.
Nice!
Would like to see more written down on how the résumé-building part works.
Would love to see something that can start from a pre-existing CV and help refine. (My current CV is my own record of projects I have undertaken, so it has a lot of detail and runs into approx. 10 pages.)
Thanks!
You can upload your current CV, and it will parse it to fill out the form for you. You can then amend or improve it, choose a design, and export it as a high-quality PDF.
I will try to write about it. I faced some challenges related to exporting as a high-quality text PDF, including multilingual support and ensuring JS messages are all translated, among others.

We’re building a new social-enabled git collaboration platform on top of Bluesky’s AT Protocol: https://tangled.sh
You can read an intro here: https://blog.tangled.sh/intro (it’s publicly available now, not invite-only).
In short, at the core of Tangled is what we call “knots”; they’re lightweight, headless servers that serve up your git repository, and the contents viewed and collaborated upon via the “app view” at tangled.sh. All social data (issues, comments, PRs, other repo metadata) is stored “on-proto”—in your AT Protocol PDS.
We just shipped our pull requests feature (read more here: https://blog.tangled.sh/pulls) along with interdiffs and format-patch support! https://bsky.app/profile/tangled.sh/post/3lne7a4eb522g
We’ve also got a Discord now: https://chat.tangled.sh — come hang!
Work wise I'm building a discrete event simulation with pysim. I manage the autonomous vehicles program and underground control center for the subarctic mine I work at, and we've desperately needed some means to evaluate efficacy of designs and forecast productivity. Using it to model scoop-truck movement and loading operations, and it's working very well. It's been a joy. I've been taking advantage of the enormous context window of Gemini 2.5 pro to have it make upgrades, fix issues, and just generally doing all the legwork.
Personally I'm having fun learning some web design and three.js as I try to debug the very tricky issues with my new personal website loufe.ca using AI is fantastic but you need to micromanage when things get complicated, I find.
I'm working on an escape room! Initially I was working on a software/hardware bundle that I was planning to market to other escape rooms but I think that is the wrong approach. So I am going to build a bunch of modular stuff in my garage and eventually start my own, its been an awesome project so far! I want a more dynamic and action oriented experience so it might not really be an escape room anymore but I don't know what to call it yet.
Escape rooms are honestly... almost always a let down but the concept has a lot of potential and there are some really neat ones that standout like this local one where you pilot an airship https://www.portlandescaperooms.com/steampunk-airship
Once I build the best escape room on the planet, I can consider selling the tools.
Some sort of escape room backbone software that links together all of the hardware according to a script is such a neat idea. It would be so cool to have something like Twine [0] to build out the story graphically, where input/output is via cues to staff/hardware rather than just text on screen. An old boss of mine used to run home-haunts for halloween. (a walk-through haunted house experience scaffolded-up in his yard) I helped him a few times, and I was always amazed by how big of a community there was. There were at least 5-6 people doing a haunt next week and would come help out at his, then he would help at their haunt the next week. My boss was even making a magazine for the community for a while. Something for those folks doing quick popup theatrical events/escape rooms that could handle some "duct tape engineering" would totally have an interested market, and if it was open source you'd get great patches.
BUT I also get what you mean, have find out what works first. Do you have a blog for your escape room progress? That sounds like such a cool thing to follow you making!
[0] (https://twinery.org/)
Have you ever visited a Boda Borg? They’re not quite escape rooms; generally, the experiences are fast-paced. Some are puzzles; some physical challenges; some, an interesting mix. Lots of computer automation to make it all work.

I’ve been working on a side project called jobswithgpt — after months of building and refining, the first version is finally live: https://jobswithgpt.com
The idea is simple: a job search site that actually works for job seekers. It focuses on listings posted directly by companies (no spam, no middlemen, no bloated sponsored posts drowning out real opportunities). It uses AI to surface better matches, recommend jobs intelligently, and pull out the most important info from job listings automatically. You can also bookmark jobs you’re interested in and track them easily — no signup needed unless you want personalized suggestions.
It’s still early, and we’re improving it constantly. Would love for you to check it out, try a search, and let me know what you think — good, bad, rough — all feedback helps. Thanks a lot for the early support!

As a follow up to my relatively successful series in x86 Assembly of last year[1], I started making an OS that fits in a bootloader.
I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes.
It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor. It's a lot of fun!

A children's book about creative problem solving and entrepreneurship.
The book is written in the Choose Your Own Adventure style. Readers get to join the protagonist Daphne on a fun, week-long adventure launching her own mini-businesses. Readers help her make smart decisions, solve fun challenges, and learn about money and problem-solving in the process.
The book has been a fun endeavor in both writing the manuscript and code! On the latter, I wrote an exporter for Twinery to Org Mode and an Emacs Org export backend to do the reverse.
The book is currently open to beta readers - Happy to let a few more in through the sign up page here: https://tendollaradventure.com/#get-notified
A few things:
- Snapshot (https://apps.shopify.com/snapshot): AI generated product photos for Shopify. Previously used Flux and Stable Diffusion but always had quality problems. Was very tricky ensuring text remained the same and the product fit into the generated background. Just integrated the new OpenAI image generation model and results are much better however their masking feature doesn't work properly so need to wait for them to fix that before I can offer the same feature of keeping text/fine details the same
- Lurk (https://apps.shopify.com/lurk): New one I just launched - allows Shopify merchants to track the prices of competitors and adjust their own in response with dynamic pricing rules. It's cool because you just have to paste a URL and it uses AI to figure out the price. Again, there's a surprising amount of things you need to figure out to make this work reliably at scale (e.g. popups, ambiguous HTML, location-based pricing, etc.)
- Origin UTM Tracking (https://apps.shopify.com/origin-utm-tracking): Simple UTM analytics for Shopify stores. Acquired this last year and its being growing nicely.
Main work: tokenization of real-world assets, but on the side I’m building two projects as a solo dev:
Looking for like-minded people interested in exploring both the technical and business sides of these systems.I'm preparing to leave the corporate world after twenty years and go get a master's in software engineering this fall in Newfoundland.
Pretty anxious about that, given how massive of a life change it is, and how much will be riding on me getting good grades.
That's super cool! Good for you!
I'm kind of contemplating the same thing - not leaving the corporate world, because I have too many bills and debts for that - but getting a PhD in something, maybe math or CS. I don't know that anyone really does that in their forties, though...
Lovely.
This is on my mind too.
Am an engineer (EE + CS) with 25 years of work experience, with a passion for Physics. Am widely known in my circles as a scientist/physicist, however, I do not actually know much. Learned some Lagrangian and Hamiltonian classical physics recently.
I personally do not mind going for even an undergrad in Physics if that would be a better fit for me to learn. :-)
I’ve also been ruminating on the idea of getting a formal education in physics since I always imagined myself as a physicist when I was a child. :)
That's awesome. I often dream of returning to a formal learning environment, I didn't appreciate how special dedicated (extended) time for learning was when I was in school.
Best of luck!
I'm working on running sequences of heap operations (insert and delete-min) in linear time instead of O(n log n) total time. It's a silly little project in theoretical computer science I have.
Crucially, to make this bound work, you only learn the final state of the heap, not which element got deleted when.
I'm also building a simpler soft heap.
Working on a site to help people find stained glass windows to visit in their towns/cities. No exciting tech (vanilla HTML/CSS/JS) and lots of data entry, but making some decent progress!

TUI browser for the Modern Web. Runs JavaScript, works everywhere, but only shows text. Quietude, noise cancellation for content. Sneak peak: https://youtu.be/rmykR_OLYhg
I also just today made a fun way to fully host a front end and SQLite back-end on GitHub for free using Pages + Actions, you can try it right now: https://do-say-go.github.io/fully-hosted/
Silly lisp-inspired language, but it turned into something different as I started asking myself more and more questions, and now it's more of a model for computation that tries to think about computers as different from looms (aka harward architecture). One where self-modification is the norm, where there is no stack unless you make one, and where there's no difference between a program extending itself or the programmer doing it (unlike LISP macros, my language, and model, does not have a distinction, there's no macros).
I'm not doing this because I'm convinced it's a great idea, or because it's going to revolutionize computing, or because it will be a good language, model or beneficial in any particular way, I'm doing it because I think it's fun, neat and interesting to think about (and talk about).
Have you looked at Kernel and wat? They use a fundamental operator (vau) to make macros, instead of a special form: https://github.com/manuel/wat-js
maru has this vau operator implicitly, rather than explicitly: https://github.com/attila-lendvai/maru
I’m working on a web based note taking app that is open source and lets you own the notes in your file system - https://bangle.io
Great name!
I'm working on an unified MCP server that can search and use a large number of tools. The current way of using MCP server (adding each MCP server directly) simply doesn't scale. If your AI agent needs to use 100 tools, you need to manually configure a lot of MCP servers. And when you feed those tools to the LLM, it may get confused and tool calling accuracy starts to drop.
This is why I'm building a unified MCP server with just two meta tools: - Search Available tools - Execute a tool
When I want to send an email, I ask LLM to use the Search Meta tool to search for Gmail related tools in the backend, then the meta tool returns the description of relevant tools. The LLM then uses the Execute meta tool to actually use the gmail tool returned. https://github.com/aipotheosis-labs/aci
I used "Claude Code" to create a local-only webapp for tracking symptoms of my chronic sinusitis, which seems to be tricky for the doctors to figure out, over time, using the "Sino-Nasal Outcome Test" (SNOT-22) questionnaire. Trying to correlate environmental and medical factors and interventions with raises or decreases in my symptoms.

Premium tooling to work with JSON Schema (https://www.sourcemeta.com).
I'm a member of the JSON Schema Technical Steering Committee, and been making a living consulting with companies making use of JSON Schema at large. Think data domains in the fintech industry, big OpenAPI specs, API Governance programs, etc. The tooling to support all of these use cases was terrible (non-compliant, half-baked, lack of advanced features, etc), and I've been trying to fix that. Some highlights include:
- An open-source JSON Schema CLI (https://github.com/sourcemeta/jsonschema) with lots of features for managing large schema ontologies (like a schema test runner, linter, etc)
- Blaze (https://github.com/sourcemeta/blaze), a high-performance JSON Schema C++ compiler/validator, proven to be in average at least 10x faster than others while retaining a 100% compliance score. For API Gateways and some high-throughput financial use cases
- Learn JSON Schema (https://www.learnjsonschema.com/2020-12/), becoming the de-facto documentation site for JSON Schema. >15k visits a month
Right now I'm trying to consolidate a lot of the things I built into a "JSON Schema Registry" self-hosted micro-service that you can just provision your schemas to (from a git repo) and it will do all of the heavy lifting for you, including rich API access to do a lot of schema related operations. Still in alpha (and largely undocumented!), but working hard to transition some of the custom projects I did for various orgs to use this micro-service long term.
As a schema and open-source nerd, I'm working on my dream job :)
That's really neat. I've been doing some JSON schema work on our products recently, especially trying to take a schema and generate info compliant with the schema for e.g. testing accounts with clean data on non-production environments, etc. I feel like the area's underdeveloped.
I recently released an AI software architect chat app.

It is an interesting discovery journey on extracting relevant information from both code and documentation with a sufficient density to stay within the context window and extracting efficient criteria from arbitrarily phrased questions.
I’ve been making photography software as an indie developer for a bit over a year now:
https://heliographe.net
A few released apps for now that are iOS/macOS, with some exciting more things in the pipeline.
If you’re a photographer who has frustrations with current mainstream photography software (whether capture/edit/publishing), I’d also love to hear from you - you can find me as Héliographe on (mastodon,bluesky,threads,x) or just email me at contact@heliographe.net :)
Hobby photographer, I shall check this out! :)
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've been thinking about something like that. So the message is not stored, but if I scan it then it's in your HTTP server logs, isn't it?
Working on my Java NLP library that can figure out what geographical location is from a piece of free text.
e.g.
"san francisco ca united states" - San Francisco, California, America
"california, san francisco" - San Francisco, California, America
"glasgow, kentucky" - Glasgow, Kentucky, America
"glasgow, UK" - Glasgow, Scotland, United Kingdom
It started as a project when I was scraping websites, and some data had inconsistent ways of writing a location or address.
The library is called location4j - https://github.com/tomaytotomato/location4j
I'm working on a pure js webgl image editor with effects, filters, crop & perspective correction, ... oh and it's opensource as unfortunately most comparable solutions are closed sources
https://mini2-photo-editor.netlify.app to try it out (https://github.com/xdadda/mini-photo-editor)
Working on supporting MCP (model context protocol) in my LSP (language server protocol) proxy: https://github.com/noredeen/lspwatch.
I wrote this tool to make instrumenting language servers very easy. MCP (both protocol and architecture) seems heavily inspired by LSP which made me curious about what it would take to support it through my telemetry-capturing proxy.
Haven't thought too deeply about how useful an MCP proxy can be but I see it as potentially a general platform for monitoring or debugging MCP servers or clients.
I'm working on a new open source CAD program for 3d printing based on Signed Distance Functions.
Benefits of SDFs over the standard Boundary Representation (used in Freecad and similar) are that you can do "pattern" operations with domain repetition, which means making N copies of a feature is O(1), vs O(N^2), you can deform objects with domain deformation, which means if you have a closed-form representation of how you want to deform space you can basically directly apply that to your object, procedural surface texturing is easy, CSG operations are easy.
The big drawback is that it is hard to provide any workflow based around "selecting" faces, edges, or vertices, because you don't naturally have any representation for these things, they are emergent from the model's SDF.
I have some blog posts on my progress: https://incoherency.co.uk/blog/stories/sdf-thoughts.html and https://incoherency.co.uk/blog/stories/frep-cad-building-blo...
I am solving the "selecting faces" problem by having the SDF propagate surface ids as well as distances. So the result of the evaluation is not just the distance to the nearest point on the surface, but the id of the specific surface that is nearest.
My next big frontier is reliably providing fillets and chamfers between arbitrary surfaces. I have a handful of partial solutions but nothing complete yet.
The most promising idea is one that o3 came up with called "masked clones", the idea is roughly to make a clone of the 2 surfaces you want to blend, mask them by intersecting with an object that is like a "pipe" along the intersection of the 2 surfaces, apply the blend within the pipe, and then add this "blend pipe" as another child of the lowest common ancestor of the 2 blended surfaces.
And after that I need to work on more standard CAD stuff like constraint solving in the 2d sketch editor.
This is super neat, cool that you have an online demo as well.
I wonder if there are any ideas on how to make this a OpenSCAD-style editor instead of interactive? I like the text-based style for simple regular shapes, but they tend to end up too simple and regular. Maybe tools like filleting edges SDF-style is a game changer?
I actually don't really like the OpenSCAD-style interface. For me FreeCAD is the current state-of-the-art in CAD.
But if you are into code-style SDF interfaces, I have some links on https://incoherency.co.uk/notes/sdf.html
A midi sequencer, which does or is supposed to do what you expect.
In the process of adding stuff like euclydian sequences, and trying to figure out how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory behind it.
It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.
Ah, I have a thing vaguely like this in the pipeline too. Fun stuff!
That's a cool project, but learning music via music theory is a bit like trying to learn English via grammar theory. It's backwards, and out of the hundreds of musicians I've met, I've never met one that walked that path.
Strong recommendation: Hire a teacher. Even with experience playing four instruments, and when I decided to learn another, I still hired a teacher.
One of my goals for this years was to get a jazz teacher, specifically for guitar.
A layoff killed that goal for the foreseeable future.
Theory has helped me practice like I think you're supposed to. More structured, more analysis. It also tickles the same part of the brain the certain comp sci topics do.
I think it came from wanting to learn how to improv, and then wanting to make my own songs. So I make a few tracks a week, of different genres, depending on what I'm interested in at the time. I've seen improvement, and I take notes about what I learned/what works.
Letterboxd for video-games! Don't know if it's novel enough but it's given me the chance to get into front-end design and think harder about database design.
Still working on Connet[1] and the associated Connet.dev[2], which is a p2p reverse proxy with NAT traversal (and hosted version of it). Currently, adding support for defining multiple points of ingress, next will be adding support for PCP port forwarding.

A social advocacy platform for small and medium sized B2B businesses. LinkedIn is more or less the only social platform for B2B social selling and smaller firms could benefit from their posts getting a bit more augmented and coordinated engagement. So we’re building a solution for a marketing manager to request advocates (employees, partners, others) to engage or reshare (tweaked in their own voice if they want) their content. Not world altering but shockingly underserved market. With few players who raised money and therefore have to price expensively, whereas as a bootstrapped side-hustle we can offer it in a flat-fee way that doesn’t “penalize” growth by charging per-user or for inactive users.
(Pre-launch [https://www.sevenbaton.com] would welcome feedback from marketing folks)
I'm teaching myself category theory, I'll kick back off a local trail, keep notes on the birds I see and read and do the problems in my notebooks. I've got Basic Category Theory by Leinster, and How to Read and Do Proofs by Solow as my references, notebook, pen and a pair of Nikon binoculars.
Can I ask what prerequisite mathematics you would need to know before reading those? I'm really interested in that topic and better understanding functional programming.
If you wish to approach Category Theory from the viewpoint of a programmer, not a mathematician, I suggest Bartosz Milewski's book Category Theory for Programmers. For this, all you need is some previous programming experience. He uses C++ and Haskell iirc but as long as you can read snippets of code, you'll be fine.
I am suggesting this since you said you want to better understand functional programming. Category Theory, as mathematicians look at it, is an extremely abstract field. If you want to do pure math related stuff in Category Theory, and only then, I would say important prereqs are Abstract Algebra and Topology. I believe the motivation for Category theory lies in Algebraic Geometry and Algebraic Topology, but you definitely don't need to be an expert on these to learn it.
Hey thank you for the excellent tips! I really appreciate it!
Trying to remain employed. I can’t lose my job in this chaotic simulation we call life.
https://undetectag.com I developed a device that turns an Airtag on and off at specific intervals. Current Airtags are detectable right away and cannot be used to track stolen property. That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location. It’s not foolproof, as the timing has to be right, but still useful.
An idea for more complete coverage: have 2 of them, and invert their intervals, such that one and only one is always on
This will work for a while, before thieves know to check for multiple airtags. Better to not detect any in the first place
Yes it's also a good strategy.
Is 4 on 1 off really the best strategy? Seems like it just makes it a 20% chance that the thieves detect the AirTag, right?
Yes, I'm thinking of offering various set-ups in the future, if I see that people are interested
Airtags are detectable to prevent abuse, how do you want to prevent abuse with your product?
Due to its timing, the device is not suitable for stalking someone. Additionally, if you place it in someone's handbag, for instance, once the AirTag comes back online and the person starts moving, they will be alerted that the AirTag is tracking them.
Have you considered adding an IMU/motion sensor?
Interesting idea... I think it would increase the price a bit too much
I wanted to know what my kids were doing on the computer: homework or watching youtube shorts, so I built https://screenspy.app to monitor them. Now I’m working on turning it into a product.
I've been using something like Google Family Link, which works fine, except that it ties in to Google Family, along with YouTube, Play Store, Google One. I'd have to kick my sister out of the group to monitor another daughter and it means there's a limit on the number of children you have; such terrible design.
I do want to give them a little privacy and it gets to the appropriate level. Like restricting some apps at certain times, access to chrome but not xhamster. Locking it for certain periods of time and having them request more screen time past 4 hrs/day. Locking the phone whenever they've barricaded themselves in the room the whole morning.
I don't necessarily mind that they're watching YT or TikTok and such. I just want to kick them out of the doom scrolling cycle every now and then.
I really like this idea of silent monitoring. Monitoring and talking about bad things seen weeks/months later. Because while I can block everything I want at home… there are other kids with free Internet access where everything is available and then I have no idea what’s happening.
If you add some remote command execution, you basically created some sort of a trojan ;-)
Really like to look of the product page!
They might as well get used to being spied upon now. Beat the rush! :)
I hope they fight back and become the generation of the linux desktop
Learning Rust by building a simple database using it.
I’ve done my share of programming languages (PHP, C++, Python, Ruby, Haskell) and for the last 10 years I’ve been working in OCaml (which I love so much) but Rust would be a nice addition IMO.
And I never implemented LSM style database before! So that’s fun.
I only just started and the pace will be slow (I have 3h/week to spend on it on a good week), if you are curious: https://github.com/happyfellow-one/crab-bucket
LOL, love the name.
LSM style should be an interesting path, especially when it comes to optimization.
I've been building proxymock, a CLI tool which automatically builds mocks and load tests from captured traffic.
Feedback appreciated - https://proxymock.io/
Working on a FOSS card game.
I realized after trying multiple tools like Supabase and Firebase, I really need to program my own solution. I don't need a bunch of *Enterprise* level features. I just need to read the card data from a database, and process the games with some simple server side code.
I hope to have the server, along with a basic front end done by this summer. Then it'll be released under a permissible license. Probably MIT.
I want a community of different front ends compatible with the same server. I suspect a straight up cli client without a bunch of effects might be popular with some of y'all.
If you want to code a frontend in Unreal, the server doesn't care. The game remains the same.
Of course your free to fork it privately, build a commerical product, etc.
Working on a web app builder that generates code via AI, much like hundreds of other tools out there. The differentiator is that the tool automatically sets up a Postgres DB (using Neon) for you. So, it's a lot easier to get started and it can handle large complex apps that require auth and database, but it can also build simple websites. The stack is next.js and code is easy to export and view.
Primarily uses Claude Sonnet 3.7 and Gemini Pro 2.5. But you can choose other models too.
You can try it for free while I'm beta testing it here: https://lumosbuilder.com?ref=hn
I'm working on a cookie clicker style web game that's secretly about AI safety: https://preview.mancato.nl/clean
My primary goal is to make a game that's fun. Secondary goal is to make you experience why an AI might do things you don't expect. Specifically, to further instrumental goals like collecting resources, refusing being turned off, things of that nature.
There are two endings currently but I'm working on adding some more.
Still supporting https://monkeys.zip - my pet art project where users simulate thousands of monkeys on typewriters for silly rewards. After which, moving on to a music creation app.
Trying to understand the possibility and feasibility of LLM on Indian vedas and ancient hindu mythology. I am thinking like there is a input box where user will enter his problem,/query and get resolved with the help of Vedas, puran and old hindu religious books.
Two things.
I have revived my work on Go Micro (https://github.com/micro/go-micro) and rewritten the v5 cli/api from scratch (https://github.com/micro/micro). As a VC funded company there was a lot of confusion around the tools we were building and we veered off in a direction that alienated the community. With the company dead, funding gone, etc there's an opportunity to rebuild value around the Go Micro framework.
The second thing I'm working on is the Reminder (https://reminder.dev && https://github.com/asim/reminder). As a muslim I feel like it's my duty to spread the word of Islam and as an engineer I feel like an appropriate way to do that is build an app and API for the Quran, names of Allah and hadith. It's a slow patient building of something as opposed to expecting anything from it.
In terms of new ideas, maybe not new but less screen time, less phones, more nature.
Currently building a CORS Proxy.
After working on it for a while, I noticed there’s a stigma around using CORS proxies, often associated with fetching undocumented APIs.
While that’s sometimes true, I’m hoping to change that perception, to show that they can also be used for accessing real APIs. It just requires the proxy to correctly handle credentials and secrets.
The idea is to open up more possibilities for building static-first apps without worrying about CORS.
Working on: Pantry Recipes – AI meal generation based on what’s in your kitchen
Over the past few weekends, I’ve been building Pantry Recipes – a mobile app that lets you quickly generate recipe ideas based on the ingredients you already have at home.
The idea is simple:
- Save or quickly select ingredients you have on hand - Tap Generate Recipes and get ideas instantly - You can also describe what you want to make free-form (e.g., "cheese omelette") and the app will generate a recipe for you.
The app is free for a number of recipe generations, then offers a low-cost subscription if you want unlimited use. It's live on the iOS App Store now: https://apps.apple.com/us/app/pantry-recipes/id6744589753
Happy to answer any questions if anyone’s curious about the tech, UX challenges, or what I learned from launching!
Cool idea! I’m a big fan of AnyList so this was intriguing.
I think it could be useful to have a “recently generated” section in the Recipes tab that lets you find things you might have forgotten to save. Substitutions could also be a useful feature. For example, if I can’t find Mexican oregano, what else can I use?
Since you are using AI, what are the chances of your app suggesting existing recipes vs "inventing" new recipes.
Also, there can be set of ingredients that should not be mixed together or be cooked in certain way. Are these cases considered when generating recipes ?
Robot walking. But really, a programming language and tools to make it easy to solve hard nonlinear control problems like walking. There are videos & source code for 2-legged walking robots (in simulation) at https://throbol.com/post/how-to-walk, and videos & source code for 4-legged walking robots (on real hardware) at https://throbol.com/
A database of indieweb/blogosphere pages that lets people search for peer content.
(1) Business process modeling tool where processes are data and not graphs. I am doing it according to the USM method. USM is kind of "open source" service management method, although it works on different level than other frameworks and standards, and is compatible with all of them.
This makes it possible to create a kind of requirement "programming language" where the requirements can be evaluated. With this language it becomes possible to create cross-references from various compliance standards/frameworks, like ISO27K, to USM, and automatically evaluate the compliance.
(2) Dance event calendar in Finland, running in production for over a year. 1-2M page views/month. Django app, but I am now implementing a copy of the unauthenticated user views to S3 bucket and delivering it through Cloudflare.
(3) Django app to handle all the data related to custody trial. Emails, SMS, notes, official records, voice memos, etc. can be attached to a timeline, and tagge and searchable. It has command line interface for adding data, in addition to UI, so I can quickly add notes and attach files.
Do you have any more information about your USM modelling tool? It sounds interesting.
No, it is not public at the moment, although I am/we are looking for pilot customers especially interested in getting ISO27K compliance.
It is very interesting. I am very surprised how well it worked out.

I'm working on an open-source Pivotal Tracker. I just started a week ago but if anyone is interested in following please checkout the repo: https://github.com/bendangelo/Iterator
I'll have a working project in about a month. But for now it's just a readme.
Working on Uncloud [1] — open source tool for self-hosting containerised apps across multiple machines. You can combine cloud VMs and on-premises to create hybrid compute environments, e.g. for cost optimisation or data privacy.
While Kubernetes offers power at the cost of complexity, Uncloud focuses on simplicity for common deployment workflows.
Progress from this month:
I'm particularly excited about the volume management system as it provides the cluster semantics to the good old Docker volumes. It uses a constraint-based scheduler that ensures services sharing volumes are properly co-located.If you're seeking something between "just Docker" and full Kubernetes for deploying applications on your own infrastructure, I'd love to get your feedback on Uncloud.

i am building a little iMessage app called Whenish.
this was spurred from group texts with friends planning a vacation or outing. we would just throw a bunch of dates that would get lost in the mix and people would forget who was open on what dates. Whenish just allows user to select dates they are free and then it will show what is the best date that works for everyone.
i have a testflight right now and if anyone wants to give it a go please do! i would love feedback :)

A Markdown-first CMS and website builder for blogs, newsletters and documentation websites.
I've been blogging since more than 10 years, and the only thing that made it possible is Markdown. That's why I've decided to build a complete publishing platform to replace the complex and fragile setups of bloggers and startups. Do you really need a CI/CD pipeline, static site builder, hosting, CDN and analytics just for a website? :/
The platform is currently 100% operational and I'm now working to Open Source it.
The best thing? You can publish directly from the CLI:

I'm still developing podcast websites with transcripts[^0] while maintaining a part-time job.
This thread made me realize I've made no progress in acquiring new clients since posting about this 6 months ago. However, my part-time job ends in May, which will allow me to focus exclusively on Fanfare. It's somewhat intimidating, but I'm also looking forward to it; the prospect of resolving this uncertain situation (either through success or failure) feels liberating.

Working on a series of interviews with gamers about how the hobby is part of their lives, called Unmuted [1]. It's been awesome to interview people from different backgrounds and see how gaming has influenced them.

I spent the weekend working on the Ansible automation needed to deploy Tomcat and Roller Weblogger for my new personal website/blog[1]. Once the loose ends are tied up with this, I plan to deactivate my Facebook account and mainly focus on the personal site + Fediverse sites for sharing stuff. This is both to be consistent with my principles, which say to disfavor closed-source / walled-garden sites like Facebook, and because it should free up some time I waste when I allow myself to get pulled into political discussions on FB. It'll probably be better for my mental health as well.

I have small solo project that I am slowly expanding on. It started as an old-fashioned text sentiment analysis more for my amusement more than anything else ( no real insights were gleamed so original version was used as a foundation for what came next ). I don't think I will ever put it out there publicly, but it keeps me occupied when I need a distraction.
A little free library style box, but not free and not a library (https://thingio.dev)
I've got an LTE module connected to a solenoid lock. The module listens for a "checkout complete" callback from a Stripe payment link which will unlock the solenoid. There's also some weight sensing involved to track the current product inventory inside the cabinet.
I built this for a family friend who does a lot of wellness outreach around combating food deserts by introducing small scale farming to local schools.
As a result of their community bee hives, they have a bunch of excess honey. So, I thought I’d build them this little honey vending cabinet for their neighborhood.
I've expanded the service a bit to be more product agnostic, maybe someone else can find a use for it.
I've been working on https://asterai.io -- a platform for developing, running and managing AI agents.
It lets you create multiple agents, configure them via the web console (such as LLM parameters and system prompts) and manage their plugins and functionality.
The system is fully plugin-based, where each plugin is a WASM program that exposes functions/tools that the agent can call, and can also hook into the query lifecycle. Because plugins are WASM, they can be written in various languages such as Rust, Go, TypeScript etc. Plugins can also act as libraries, which is possible because of WebAssembly Components (a great piece of software!) -- so you can dynamically call functions from other plugins within your agent, and you get type support for your chosen language too (with codegen via WASM Components tooling).
More recently, I've been working on an SSH server for agents. The idea is that you can add public keys to your custom agent and then SSH into it to talk to it easily from terminal.
If this sounds interesting, feel free to join our Discord! The project is still new and feedback is highly appreciated. http://asterai.io/discord
This looks interesting, how do you plan to handle agents which operate apps with a UI - for example playwright, obsidian etc. Or is this out of scope?
Thanks!
That's a good question. Currently, there is one way to do it. The client querying the agent receives JSON-encoded values that are returned from plugin function calls made by the agent. These values are received alongside the agent token response stream (via SSE). So plugins can essentially emit events that the client can forward to the UI application, such as to click a button etc. The limitation with this is that there is no built-in way to send a success/error status back, it's one way only. It works well for actions that are infallible such as simple UI actions.
The client here would also need a way to interact with the target program of course, e.g. from a JavaScript browser you can click buttons and manipulate the DOM, or from a VSCode Plugin you can interact with the editor etc.
It's definitely something that can be improved though! I've been thinking about some type of MCP interoperability that could maybe assist with this.
so I'm working on side project to make managing and exploring your music library easier.
The idea is you can set a few filters (like bpm, key, decade, genre) and then swipe through random songs, accept or reject them for inspiration or playlists. Kinda like Tinder but for digging through your own tracks.
It also tracks what's trending on TikTok/YouTube/SoundCloud weekly, so you can find stuff that’s blowing up, filterable by region. Plus it can build smart playlists automatically based on rules you set (like “new 90s house under 120bpm” every month).
It is just a tool to make working with your existing local/Apple/Spotify/SoundCloud library faster and more creative.
Here's a demo of it: https://filtered-f.web.app/
Will it work with Beets? :)
I hadn't heard of Beets until you mentioned it. I took a look at it and yes, it'll work with Beets.
I was using Python to get the bpms and keys on local tracks, and was going to start figuring how to fill in the missing metadata.
Thank you!
I am working to better understand AI agents.

I'm currently working on Academy Referral* (https://academyreferral.com). It's a referral platform for martial arts academies, allowing owners to reward their students for bringing in new members.
I've trained martial arts for a few years, and have always been that person who tries to introduce those close to me to the community. I know a lot of other people do the same.
Now, I don't care that I wasn't rewarded for it, but why not? We have point-based programs for nearly everything. Why not for martial arts as well?
* Have a few academies in the process of testing it out. Still a lot to do, including the demo video that isn't going to load on the main page.
I was recently looking for a simple minimalist app launcher for iPhone that would respect my privacy and didn’t come with a stupid subscription plan, so instead I made my own! https://apps.apple.com/us/app/applist/id6743515756
I also published the list of url schemes / universal links on GitHub: http://github.com/sxp-studio/app-list-catalog
That's cool. Reminds me of the Windows phone launcher.
Just downloaded this. This is a great format for how my head thinks, especially for apps I use periodically but not so often that I want them on the main screen. Thank you.

I've been writing a software synthesizer, I want to use it to make an album when it's finished. As of now I've implemented a basic subtractive synth with the usual primitive oscillators, random noise, high and low pass filters, and an ADSR envelope. I've implemented input and output "drivers" for Windows and Linux: WASAPI, ALSA, Windows Raw Input, and evdev.
Soon I'll start work on Lua bindings. The idea is to configure the core engine programmatically. Hook up inputs, modify synth parameters, route output. It's going to be inferior in every way to something like SuperCollider, but I just think it'll be insanely cool to materialize music from thin air. I've learned lots.
I'm trying to figure out how I can turn hobby products (that me and family and friends are using) into real products for a wider audience. So far, I've found 2 main failure cases:
1. While I can share source code and documentation with trustworthy people, that won't work at scale: the market would get flooded with Chinese clones that re-use my Open Source software but then I have no ongoing revenue to fund support / maintenance.
2. Especially for products with a physical component, shipping, taxes, refunds, CC chargebacks etc. add considerable overhead. Plus I need to add in Amazon fees and marketing spend. And suddenly I need to charge 8x the manufacturing price, which means I either need to massively cheapen out with quality, or it's going to be a very premium product.
https://mitte.ai — an AI image generator with focus on quality and details
so you can get logos / icons that doesn’t look AI generated.
it comes with Photoshop-like editor (https://mitte.ai/editor) so you can zoom into details and change / remove anything, or upscale, etc.
I built it for myself but now there’s good amount of paying users as well.
So I wanted to try this and it turns out you can't sign up?
simply go to the sign in button and then there is a reset password and then when you click on it , there adds an optional sign up and when you click on it , it leads you to mitte.ai/join which says Not Found.
Kind of interesting, wappanalyzer shows its written in erlang? So are you raw dogging erlang or maybe elixir or gleam? What's the tech stack behind this.
Where are you generating the images / videos at? Are you using something like openrouter api or are you self hosting the gpu / using aws for it??
I am also interested in what percentage of users are paying? and also the abuse vector that might arise from generating some pretty down bad images... , are all images that are generated here public or what exactly??
You can sign in with Google.
I had to close the sign up because there was so many abuse coming from regular sign ups.
'Sign in Google' is great because it eliminates low quality traffic who never pays and tends to be there for abusing the system.
We need a better mechanism than this for testing the abuse system, because I use proton mail and though I have a gmail, I don't want to use it anymore... I know Oauth is convenient, but please for everyone's sake, can we guys not either add literally every single Oauth / I think one of the best options is probably matrix OAuth with a captcha and rate limits
https://account.matrix.org/
Seriously, I don't mind a sign in option, I just don't want to be forced to use gmail / inferior privacy solution to use your app, no offense.
> Please add more Oauth solutions > I am investigating what can be the most universal Oauth solution while still preventing spam unlike emails, sounds interesting enough of a problem,IDK
Sounds like keycloak can sort of allow some sort of decentralized option or have many and I mean many including the matrix sign in as a option.
Keycloak also has strong integration in a lot of languages, there are other projects like authelia etc. but for some reason keycloak actually seems to me of having a little bad ui but still absolutely great in what it does
But authelia/ authentik are easier to host/integrate IDK
I see that it does drawing and illustrations as well. How good it is for science illustrations, like those seen in a Physics book.

Whispers is a self-organizing, belief-driven mesh where nodes propose, verify, and evolve solutions through dynamic, decentralized consensus.
Basically a shared knowledge graph of proposed partial inferences in CRDTs using verification as a merge function. There're some issues I know I'll run into with e.g. admissibility but I have some solutions in mind.
I'm in the very early stages but I think it's a simple idea so I have high hopes for a cool demo soon.
I'm working on a site that lets you tile and watch multiple videos from different platforms all at once.
You can drag and drop links from YouTube, Twitch, TikTok, or Kick --and they show up in a grid.
You can reload or remove streams without refreshing, save mixes for later, and share them as links. It works best on a really big screen --phones aren't really supported and even notebooks are too small to get much benefit.
There's no backend, no login --everything runs in the browser.

A custom Python/Django based mini-app (mini — at least for now) that will allow me to import transactions sanely and safely to my local GnuCash install.
I’ve been doing tedious manual entry for a bit over two years now and after having missed three consecutive months, the only other option was to bail.
As a start it should help with 3 main things:
- Translation, categorization: my source documents aren’t in English but my GnuCash entries are. This is one of the reasons I don’t use the built-in imports. (This should shave off at least 90% of time spent entering data)
- Human-error prevention: there were at least 5 times where it took me over 15 minutes to reconcile a discrepancy because I entered some number or some account wrong somewhere.

I've been working hard on MCP Router. MCP Router is a free desktop app (Windows/Mac) that lets you securely manage local or remote MCP servers via GUI, with access control & logs.

I'm working on a multicast dns implementation in OCaml. It's a library allowing one to build custom queries/responders, plus a conventional querier that can be used as a stub resolver for .local to get the resolver functionality of avahi.
My main motivation was to implement a service that publishes the addresses of containers and vms that I run on my workstation to my local network, but it gradually has grown into a full-blown implementation of RFC 6762, which has been fun.
I'm working on a mobile app for exploring places with Wikivoyage (https://mapvoyage.app) and a wikitext to structured JSON-tree parser to support that (https://github.com/bcye/structured-wikivoyage-exports) and am finally getting pretty close to a beta version :) I hope to unify the workflow of going back and forth between Wikivoyage, the favourites list on Google Maps and notes into a single app.
I'm working on a travel planning application. I know a lot of other apps exist, but I'd like to build one myself.
https://github.com/kenrick95/ikuyo
So far it has some sort of activity calendar + expense tracker
There's still so much ideas to implement, like adding map, improve UX of creating activities, to-do list, etc
I've used it once or twice of a short trip, but in 6 months time, I'll have a 2-weeks trip, so that's my self-imposed "deadline" for this project
Anyway this project is a pure static web page and all the 'back-end' is handled by InstantDB ( https://www.instantdb.com/ ) after I saw their submission on HN >.< So far it has been quite a good experience overall except maybe the permissions model which can be a bit confusing to me
Awesome project! Which other alternatives did you find/get inspiration from? I haven't really found great options in the (more broad) travel planning space, which is why I am building in it.

I'm working on a fantasy console that work on iOS and iPadOS https://github.com/moechofe/LowResRMX
My goal is to create games on the go, during my commutes.

Fantasy consoles are awesome, very fun project and I love your demos. The way the bombs fall with the music in Kaboom is smart. I've thought a lot about building a hardware PICO-8. Not just running the software, but implement the APIs for real hardware and transpile the game cartridge. One of those ideas that will probably forever stay in the back of my mind.
Critic (https://getcritic.dev) - An improved inbox for GitHub pull requests
The experience with GitHub can be terribly frustrating when it comes to managing the stream of incoming pull requests. The default inbox and notification systems are not so good, and not flexible. Critic allows to create any number of sections, each section being defined by an arbitrary search query.
I would now like to expand it to provide a better code review experience, similar to what Graphite or Reviewable may provide - but under as an open source project. Source code is available at: https://github.com/pvcnt/critic

Three Kind Words (https://threekindwords.com)
It’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. The first two cards are unsigned, and the last one reveals who sent them. It’s meant to be a slow, kind surprise in the mail.
I shared this on HN a while back, and it gave us a quiet little push. Since then, we’ve sent 246 out of the 300 postcards we set out to deliver this year. Things have slowed down lately, but the whole thing is automated, costs almost nothing to run, and has been a lot of fun to work on!
Just some feedback, I think this would be much more compelling with better choices of messages. It feels like the first two words are setting something up and the third should have some kind of payoff, but a lot of the messages don't work like that. The third word is usually predictable and obvious and something of a letdown "Never give....up".
There's really nothing in that list that is interesting enough to send to anyone in my life. I'd be wanting to send something very specific like "Remember cycling Iceland?" or "Soy chicken success" or something.
I get your concerns about "writing something inappropriate" but you could probably let people choose 3 words from a list of a few hundred pre-vetted words?
Or just moderate them - 100 three word sentences a year is a very very achievable pace.
thanks for this genuine feedback, it's really helpful insight. i like your idea of pre-vetted words and imagine there is something i could do with an LLM to moderate user generated messages.
"soy chicken success" hits close to home :D
Learning iOS development by building a the habit-tracking app I wished existed - habit tracking has been done to death, but I couldn't find anything that worked exactly the way I wanted, so I figured I'd build it. I've found Swift / SwiftUI alternately delightful and infuriating so far. Most of my experience has been with web tech, so it's exciting to build something that doesn't run in a browser.
I'm working on an IDE for lawyers: https://tritium.legal
It's inspired by VS Code and hopefully positioned to eventually be a Cursor-like experience for transactional lawyers. The LLM integration isn't baked in yet to keep the in-house onboarding frictionless.
It's a desktop application written in Rust. It uses egui (an immediate mode UI library) for speed.
I'd greatly appreciate any comments.
Create a two-sided deal review app: https://dealcred.com
I work a lot with smaller investors, in real estate, private money lending, etc. It's sometimes hard to do due diligence on someone, and after having a couple bad deals and realize over 30 people were scammed, I wished there was a simple review site where you could see someone's past reviews.
Site is 80% there, hoping to enter beta in the next month.
Language learning app for intermediate learners who want to practice reading and listening:

I'm trying to read a kid's version of The Odyssey in Greek and to be able to understand my partner's mum, and these are the features that I wanted.
Also, I wanted to experiment with "what would an app like this look like if we could trust AI to be very cheap/fast/correct?".
- So, for example, it's a fully generative dictionary & search, e.g. the dictionary entries/metadata/example sentences don't exist until the first person searches for them!
- You can upload any kind of content (image, audio, text), and it'll automatically transcribe, translate, annotate, etc.
I'm prototyping a Depth Anything[1] -assisted segment annotation tool, with an eye toward plant detection in non-agriculture environments (where the backdrop is an endless sea of green complexity).

I’m building ninja.ai — it looks like a one-click App Store for MCP Servers, but the real goal is much bigger: creating a “Universal Fabric of Context” that lets AI tools tap into structured information across the web easily.
It started when I found it surprisingly hard for my partner to install and connect MCP Servers — even simple ones. I realised if we want AI agents to really interact with the web, it needs to be as easy as installing an app.
Right now, you can browse, install, and connect servers in one click. Over time, it’ll make AI integrations as easy as installing an app — no messy APIs, no custom scraping.
If you’re working with AI models, agents, or data-heavy tools, I’d love to hear what kinds of “context pipes” you’d want to see added.
I've been thinking about the need for something like this. Another person told me the idea was like Neo in the Matrix saying "I know Kung Fu." I think the most powerful idea is to create unique bundles of context for specific use cases. Context A + Content B = best context for Situation C.
I am working on making it easier to learn languages. We provide a platform for teachers and educators to create their own language courses. The platform offers features similar to software like Babel or Anki, along with some unique features for phonetics study and customizing the learning experience.

Lighthouse (https://lighthouseapp.io/) - a different take on RSS readers, focusing on inbox zero
RSS readers show content based on the feed they're coming from, and show read and unread items in the same list. That makes it difficult to know which items you've already seen, and is especially annoying for managing items that you want to read at some point but not anytime soon.
Lighthouse splits it into Inbox (new items) and Library (bookmarked items). This makes it possible to process new items quickly, and take your time with reading them.
I recently started working on a fishing journal/log kind of app. I got that idea last year when returning from fishing with dad, that it would be nice if we could track what we caught each time we went fishing, where we went, and to track some details (water and wea details). There apps that already do that, and one could also use Excel or just paper notebook, so I'm making this mainly for us and his friends to use. It's still early, but I'd like to add groups so you can exchange messages or catches with your friends, add stats allowing you to see for example at what time and where you caught most fish, or using which lure or bait. The app is in Serbian though, but here's a link if you want to check it out: https://buckaros.com

Is there any difference to the existing one that made you built another one?
Yep, it notifies you when you get comments on your HN posts. The existing one only tracks replies to comments.

I'm working on Damon[1], a Nomad Events stream operator that automates cluster operations and eliminates repetitive DevOps tasks. It's a lightweight Go binary that monitors the Nomad events stream and triggers actions based on configurable providers.
A few examples of what it can currently do:
- Automated data backup: Listens for Nomad job events and spawns auxiliary jobs to back up data from services like PostgreSQL or Redis to your storage backend based on job meta tags. The provider for this is not limited to backups, as it allows users to define their custom job and ACL templates, and expected tags. So it can potentially run anything based on the job registration and de-registration events.
- Cross-namespace service discovery: Provides a lightweight DNS server that acts as a single source of truth for services across all namespaces, solving Nomad's limitation of namespace-bound services. Works as a drop-in resolver for HAProxy, Nginx, etc.
- Event-driven task execution: Allows defining custom actions triggered by specific Nomad events; perfect for file transfers, notifications, or kicking off dependent processes without manual intervention. This provider takes in a user-defined shell script and executes it as a nomad job based on any nomad event trigger the user defines in the configuration.
Damon uses a provider-based architecture, making it extensible for different use cases. You can define your own providers with custom tags, job templates, and event triggers. There's also go-plugin support (though not recommended for production) for runtime extension.
I built this to eliminate the mundane operational tasks our team kept putting off. It's already saving us significant time and reducing gruntwork in our clusters.
Check out the repository[1] if you're interested in automating your Nomad operations. I'd love to hear your thoughts or answer any questions about implementation or potential use cases!

I made an electronic board game: https://github.com/seanboyce/Calculus-the-game
It's compatible with Settlers of Catan. However, I plan to make my own rulesets, artwork, manuals, etc. It will not be a commercial product, of course you can make your own with the files I provide.
Right now the boards, electronics, and firmware are in good working order. Although the routing is pretty YOLO.
It feels like there's a lot of unpleasantness going on in the world right now. I thought maybe I could put my other projects aside and try to make something that might brighten your day (It certainly has enough of LEDs).
A big TODO is to replace the 0402 SMT components with something larger and easier to work with like 0603. I'll find time within a week or so and push it to the repo. (I am notoriously cheap and only keep 0402 in stock)
Very cool, i like it a lot!

On the "side projects" side of things, I've been working on a "boot to EndBASIC" disk image since December with the goal of creating a small "dev kit" box that boots quickly and directly into the interpreter. The disk image is pretty much done for a first release, so now I need to get to the design and 3D-printing of a case for the board+screen combo. The latter is brand new territory for me, and I have a self-imposed deadline of June when I'll be presenting this at BSDCan.
... but I've also taken a small detour to improve the EndBASIC website and provide a dynamically-generated gallery of user-uploaded projects. This has been a deficiency for a while and I felt it'd be easy to add it, right on time for the "dev kit" release.
Stay tuned!

I started experimenting and I think this builds out pretty neat estimations from jira tickets/other descriptions. When I was sitting in the CTO role, I spent a ton of time talking with people about how long/short various projects would be. When I was a developer, I hated the estimation piece because it felt like it was both keeping me from building and was almost never done with enough context to get really accurate results.
I was playing with the OpenAI API and I noticed that they can actually return a set of probability x next tokens and I thought that it might actually give you kind of cool ways to see the distribution of potential outcomes. (You can see an example here: https://universalestimator.com/estimates/c68db45b-7622-4bab-... that looks at a detailed ticket for implementing filtering on a dashboard.)
Let me know if you have any feedback, it's free with the promo code TYHN. If you run into any issues, please send me an email at earl@unbrandedsoftware.com
Cool idea! Does it take your team’s prior estimations into account to improve future estimates?
No, but it's on my roadmap! https://feedback.universalestimator.com/p/calibrationnorms-f...
Right now, it asks you some follow up questions and assumes you're a medium sized org, but I'd like to start to move that into configuration and do some sort of time/bayesian expiration of memory/information as part of the questions it asks.
I think a ton of the variance between teams is probably captured by some version of a few calibration questions, aka: - How large is the org? - What region is your org based in? - How long does it take to get the smallest possible change into production?
I'm working on a better frontend (in sveltekit) for Udio - music generation app. Udio has good models to generate audio, but awful UI and organization/management tools. My frontend allows collecting all the generated content from udio, organize them by topic, rate them with 5-star rating system, add custom labels, filter by these, make playlists, generate prompts and create an arbitrarily long generate queue (udio allows you to create 4 prompts simultaneously so you can sit in front of UI babysitting it if you don't have custom tooling and you want to actually use your 4800 credits you paid for). I use LLMs heavily here, so the quality of code is so-so, but work very well for me and I'm having a lot of fun with this.

I am working on a telegram bot deployed on cloudflare which is just a basic app for van drivers to sign up on a fixed location near my area and see which drivers are online and see how many people have sit in a van which the drivers can increment/decrement by just chatting with the telegram bot who want to go to a popular spot where I have to go to quite daily because I am studying at a place which is way far away and its the most economical and sane method to travel..
Yet my problem really arises that its too luck based, sometimes I can be the last guy, Sometimes I can be the first guy so I have to wait for the van to get fully occupied which will take a lot of time...
I have just made it, and I find it pretty nifty, I made it all completely via AI and this one absolutely crazy good youtube video on deploying telegram bots on cloudflare...
Also, I had seen this telegram bot ai maker idea on HN a few days ago, So I had also created a project which you can chat with the microsoft deepseek r1 post training bot for free because the api key of open router for this model is free, It doesn't have incremental streaming or multi chats, really basic, and It can generate me the code but I am not sure how I would deploy that code .. , I used to think its easy but not... ,any resources out there? (Though I want to open source this, but I am not going to be building this ai idea further because I lack time and I have to study)
After trying to start a business for a year, I basically gave up negotiating with VCs.

I’m working on LookAway (https://lookaway.app) to help people stay healthier and more productive during prolonged screen time.
My main challenge has been making meeting detection more robust -- it currently uses both mic and camera activity, which led to a lot of false positives. In the next version I’m switching to mic only (the camera caused most of the noise) and I’ve added a way to identify which app is using the mic, so users can exclude non-meeting apps.
I’ve also added plenty of small tweaks throughout to make LookAway even less interruptive. I’m excited for the next release!
I'm working on making Anubis way less aggressive so that it only challenges the worst of the bad bots. I found a pattern that the bots can't fake client side and I've turned that into a sample rule that I've deployed to my website.
This is coming soon to an Anubis near you!I shared this last month as well but I’ve added a couple new features since then: a weekly digest email, a list of what you’re tracking and a price history chart.
I’ve been building https://lowlow.bot, it tracks price changes on any website. I was inspired by https://camelcamelcamel.com, but wanted something that worked for more than just Amazon. It’s been handy for big purchases I’m ok waiting for and stocking up on recurring non-perishable essentials when they go on sale. It also lets me know when something has come back in stock.
How are you scraping the prices? Are you using AI for that?

I’m building a small integration to take scheduled transactions in YNAB and display them in any normal calendar application. I’m hoping to add historical transactions one day as well to help with reconciling.
https://calendarforynab.com
Any feedback is welcome!
I once saw an idea on here[1] about putting a lot more historical information into a calendar, including past activities. It resonated with me and I wondered if bank transactions could be part of this activity layer. At the time I was working on a real-time integration between my bank and YNAB so I was already thinking about the space.
1: https://julian.digital/2023/07/06/multi-layered-calendars/
For people like me who didn’t know what YNAB means:
YNAB stands for "You Need A Budget." It is a privately-owned personal budgeting software company.
I wrote a novel in French a couple of years ago that I want to translate to English. The way I do it is paragraph by paragraph: copy/paste a paragraph in OpenRouter (Sonnet or Gemini), get back the translation, and rewrite/adjust it.
It works well but copying/pasting back and forth gets old very fast, and it would be better if the process was done inside the word processor. For some reason (various reasons) I still use Office 2003, which doesn't have any AI feature. (It does have a "translate" function but it's awkward to use and not very good.)
So I wrote a macro to send selected text to OpenRouter and replace with the response (with a system prompt that says to only output the translation, otherwise most models start with "Here's the translated text:")
I had never written a macro in vba; I got started with Sonnet and adjusted many parts with the help of StackOverflow (which turns out to have more information about vba than Sonnet...)
And finally it worked; and it turns out to be an incredible boost to translation productivity!
I've been working on https://textquery.app -- query raw data from your desktop.
I love exploring data, but it always felt clunky to juggle multiple tools, write code/commads, just to import and query a dataset. While there are multiple GUI tools for databases, none are focused on raw data.
TextQuery is the tool I built to solve that. You can import CSV, JSON, and XLSX files and start querying them instantly using SQL. Want to create a chart? Just hop over to the Visualize tab.
I'm also rolling out a major update this week — adding tabs, filters, a redesigned UI, and keyboard shortcuts.
Looking ahead, I’m planning to expand support for more formats (like Parquet and ORC) and data sources (like Postgres and BigQuery), so you can import data from anywhere, and query it right from your desktop. Something like a local data warehouse. With Apple Silicon, the capability of a desktop can make it very cost-efficient compared to something like BigQuery, Snowflake, or Athena.
Happy to hear any feedback!

In little bits of free time I get here and there, I've been working on using reinforcement learning to build some better bots for my favorite multiplayer game. Project is up here: https://github.com/cgadski/autotude
So far all my work has gone into the technical side of setting up the game (a Java app written in 2010) to work as a reinforcement learning environment. The developers were nice enough to maintain the source and open it to the community, so I patched the client/server to be controllable through protobuf messages. So far, I can:
- Record games between humans. I also wrote a kind of janky replay viewer [1] that probably only makes sense to people who play the game already. (Before, the game didn't have any recording feature.)
- Define bots with pytorch/python and run them in offline training mode. (The game runs relatively quickly, like 8 gameplay minutes / realtime second.)
- Run my python-defined bots online versus human players. (Just managed to get this working today.)
It took a bunch of messing around with the Java source to get this far, and I haven't even really started on the reinforcement learning part yet. Hopefully I can start on that soon.
This game (https://planeball.com) is really unique, and I'm excited to produce a reinforcement learning environment that other people can play with easily. Thinking about how you might build bots for this game was one of the problems that made me interested in artificial intelligence 8 years ago. The controls/mechanics are pretty simple and it's relatively easy to make bots that beat new players---basically just don't crash into obstacles, don't stall out, conserve your energy, and shoot when you will deal damage---but good human players do a lot of complicated intuitive decision-making.
[1] http://altistats.com/viewer/?f=4b020f28-af0b-4aa0-96be-a73f0... (Press h for help on controls. Planes will "jump around" when they're not close to the objective---the server sends limited information on planes that are outside the field of vision of the client, but my recording viewer displays the whole map.)
I've been working on a web app that tracks ammo prices from various US ecomm merchants with the shipping costs included. It also tracks price trends and historical prices.

I’ve been building an Elixir app to poll RSS feeds and pipe new entries to Discord.
Performance is rock solid, and it’s almost ready to release, I just need to tweak a few things (like free trial with no CC).
I have a very long to do list, and ultimately want to extend it with “change detection”, e.g. notify when an HTML element on a website changes.
All feedback is welcome
https://feedsync.net
I've been using elixir to build an app that lets an administrator add new rss feeds, render the article titles and summaries to a single page, scroll through them and push the ones they like to a landing page as a collection to read later. Many of the sites I like don't have the conventional RSS "structure" so I have to modify my main parser and adapt it to the outliers. I'm curious, how do you adapt to feeds that don't fit the conventional RSS structure? I was thinking of just using an LLM to automate it as I keep using Claude AI to expedite the process.

7 years ago I posted my dotfiles at https://github.com/nickjj/dotfiles.

Over the last week or so I extended and polished that script to make it even easier and customizable, including adding Arch Linux support. The next step is to start installing and configuring GUI tools instead of only focusing on command line tools and environments.
I just used it the other day to set up a fresh work laptop in 5 minutes. Given the script is idempotent I run it all the time on my personal box.

I've been working on mock: https://dhuan.github.io/mock/
the process of creating APIs for testing and automation should be as easy possible. the tools that exist nowadays for this purpose aren't good enough IMHO, which led me to build it.
I've been working on onsite deployments for https://www.keystash.io, which is a Linux SSH Key and User management system. It's been going for a while now and I am finally implementing onsite deployments as so many customers actually want to run this themselves. When we started, we really thought customers wouldn't want the hassle of another piece of infrastructure to manage, guess we were wrong :-)
Onsite deployment is a lot more difficult to make slick and easy. We've been thinking about the best way for our customers to deploy while reducing the load on our support team. So far, we are thinking about RPM's, Debs and Docker and trying to make this as close to a '5 step process' as possible.
I would love to hear people's thoughts on other mechanisms that make it easier for SRM's / DevOps to manage key platform infrastructure software.

I'm working on a Kaggle competition about predicting subsurface models - a map of the geologic layers beneath a given area - from seismic data.
I don't expect to place competitively but I learn a lot from these competitions. I like competitions like this that are connected to physical problems and datasets (though sadly this one is largely simulated), I learn as much about the broader world as I do deep learning. I've always idly wondered how seismology worked, and now I have an excuse to dig into it.
It's also given me a greater appreciation for the "seismology" we perform in our day to day, like knocking on things to see if they're hollow, or (as I learned here a while back) the way battitores test the porosity of cheese by knocking on it with hammers.

I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the tool will run everything in parallel while caching as much as possible.
Why should I use this and how is it better than Bazel?
If you are a small to mid-sized team, moving to Bazel is massively painful and basically requires up to one full-time position to provide your team with a good experience.
Grog on the other hand let's you keep your existing build setup while just parallelizing and caching it. It's not a full replacement, but it's more than enough for most mid-sized teams that want to have fast mono-repo builds.

https://visitorquery.com a proxy & VPN detecting tool that does it's thing based on the specifics of a connection rather than parsing list and known databases which makes it very effective against residential ones too.
Working on redesigning my SaaS template. It uses Dokploy to deploy the NodeJS app, and Pocketbase instance within the same server, so DB reads and writes are very fast. Also doesn't use the Pocketbase client library at all, all calls are wrapped in their own API routes and everything is server side rendered.
You might ask why use Pocketbase at all, and I'm not sure anymore. I suppose the dashboard is great, built in auth is great (although I've had to write cookie middleware to make it SSR anyway). I wish there was a lightweight Pocketbase/Supabase style "backend in a box" setup that didn't push the whole client library directly communicating to DB paradigm.
I am working on a PromptLibrary (https://promptlib.prashamhtrivedi.in/) to organise my prompts and make it accessible from multiple clients (Including chatbots (via chrome extensions), CLIs, IDE extensions amongst the few).
I wanted a library to store my own prompts once and retrieve it in multiple locations (i.e. Try something on claude desktop and then once I wrinkle out the edges, load it in Roo code or claude code and use it.) Give some variables to the prompt and creating infinite versions of same prompt by providing the value. Or having the versions of each prompt.

It has been fun so far! I tried importing from fb/ig by using a meta app but it has been a horrible experience so I scrapped that ^^
I am extending my pet project menuop.com, a digital menu maker for restaurants. I plan to integrate AI to enhance visual impact, analytics and recommendations to restaurant owners.

I'm still mulling how to go about porting my tiling window manager for Windows[1] to another platform, or even if I'll do it at all. There is some demand, but I don't know if there is _enough_ demand
Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so

Building an IP Geolocation guessing game: https://abdullahdevrel.github.io/ipguessr/
Let me know if you have any feedback or feature requests.
Very interesting idea. Are those IPs real? Where are you getting these from?
I appreciate you enjoying the game! I work for IPinfo but initially made it as a sort of meme for our users.
I'm generating random IP addresses on the frontend, then making an call to our free API to validate the "realness" of the IP addresses — mainly to remove bogon IP addresses, non-routable IPs, and IPs from large ASNs (national ISPs, the DoD, car companies, etc.).
Our free API supports 1,000 requests per day from unique IP addresses, so there shouldn't be any issues for low usage. However, if we get more power users who enjoy the game, I’ll switch to our Lite API service (which is also free, https://ipinfo.io/lite) to validate IP addresses, as it supports unlimited requests.
Let me know if you have any feedback for me :) I made it mostly by "vibe coding", I will write a post about the whole process of it.
You can download data sets from Maxmind.
I work for IPinfo — I described my process of how I made the game in the other comment.
Using a dataset-based implementation would require me to have a backend, which is out of the scope of this project. Right now, I'm generating random IPv4 addresses, but if I were generating random IPv6 addresses, I would have to go the database route. For that, I would use our free IPinfo Lite dataset: https://ipinfo.io/lite
My colleagues actually developed an extremely fast algorithm to select truly random IPv6 IPs from a series of CIDRs, which is what you see reflected in our dataset.
Let me know if you have any feedback or suggestions for me, please.

I am working on the https://moviemovie.club/about, it's a tiny website about film review.
It works like a run club, where you have to make a review first to see other people's reviews.
I am currently implementing watchlists, comments and a mural to make it feel a bit less lonely. Right now I like the UI but it feels to lonely.
This seems like it would only work if “reviews” would be something rare to come by. Like some forums where you have to contribute to be able to download attachments, or see higher level subforums.
But reviews are everywhere, good ones too so it will be a hard chicken egg problem to solve.

Unlike apps like Waze or Radarbot, Catchcam doesn’t track your location or require an internet connection. Just plug it into your USB socket, and you’re good to go.
Key features:
• Built-in speaker and LED for alerts
• Preloaded with 66,000+ known speed camera locations (more to come)
• Easy updates via drag-and-drop on your PC
It’s been a fun project to build, and I’m excited to see it help drivers stay away from speeding tickets while keeping their data private.
I’d love to hear your thoughts or suggestions!
Here is another thread today that could give you prospect ideas. https://news.ycombinator.com/item?id=43812856
in what way does this help drivers "stay safe"?
Safe from speeding tickets of course!
I’m working on supporting photo posts on my blog (Kirby), I bought a new camera and thought it would be nice to share them in one place (Cross post to Mastodon).

I'm making some minor changes to my personal site/blog to improve contrast, have a more uniform usage of colours throughout, and also replacing "categories" with tags so that I can have related content easily linked and searchable.
I may also finally finish implementing WebMentions support too as a kind of comment section.
I may also work some more on my long-term relaxation/creative maze generation and solver project.
At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.
It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.
To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.
Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".
The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.
So I guess what I'm saying is I've been casually looking around at jobs this month.
This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.

I develop Chips of Fury, a poker app for playing privately with friends. Currently I am building support for lots of home game variations like pineapple (regular, crazy, lazy), different Holdem variations like Super, reverse, super reverse, blind man's bluff etc and many more. I am thinking about how to implement AI bots for a wide range of variations.
Ah, I've made the same! I made a very flexible turn-based framework - write the game logic on server in javascript, then state+options are given to clients, so platforms (swiftui, web, unity, webxr etc) "just" have to implement UI on top (Also means I have a default/debug view, which works for all games). The games can run offline (via javascriptcore on ios, natively on web etc) and supports bots for all games (they randomly choose options on their turn) which has a very simple opening to get some reinforcement learning in.
Then specifically I was making an app which let me customise rules for poker - extra streets, antes, throwaway cards, passing cards, multiple boards, multiple decks, etc to support as many variants as possible, and ideally, stumble across new ones.
As an aside, I posted to reddit for research of other home variants people play (Basically to stumble across more fun variants in our home games) there's a few good alternatives I've not heard of in here!
https://www.reddit.com/r/poker/comments/1i91mnz/what_are_you...
I've run out of steam a little bit (burnt out & seeking work isn't great for own projects), but has been an excuse to learn swiftui. I'd be tempted to team up with people to keep the project alive...

I'm building a client-side encrypted personal management tool for myself, with support for file encryption:
While Git is great at asynchronous collaboration, its a bit clunky to try and work on the same commit with other devs or across devices. This is because Git tracks what changed, not how it changed.
It'd be cool if you were on the same branch as somebody else, or another device, and your working directories could be synced. It'd also be cool for the commit history to be a bit richer, so you could see who, what and when for a change at a keystroke level.
So I'm working on real-time sync for Git! I'd represent the working directory as a tree CRDT [1] and sync that through FUSE and p2p networking.
Not sure whether this is actually a good idea! This is a POC :)
[1] https://martin.kleppmann.com/papers/move-op.pdf
One idea I have had for years is that it would be great if file system would support structured data.
This would combine well with your idea.
So let's say that I change python source code, the "file system" would understand the syntax of python source. Your tool could then use this to derive the sematics of my change, i.e. "added a function foo() with the following signature and body"
Still working on https://theretowhere.com since I announced it to HN in February.
It's an website who's goal is to make it easier to find apartments/hotels/etc that fit your housing preferences (starting with places that are close to the people and things you care about). It's flagship feature is the ability to make heatmaps of cities based on your preferences.

What I'd love to be working on: Try to initiate a high voltage arc through the air to a target device, and modulate it to send "Data over Lightning", like Alyx does in Half-Life 2. It won't work the way it does in the game, but I'd it's an idea I've had for a long time and I'd love to prototype it some day.
https://workplacify.com/ - an open source desk booking software. Can be self-hosted.
There is some small improvements to make but I want to focus on onboarding via a sandbox environment first next month.
I have two:
The first is a preventive maintenance and calibration tracker (https://pmcal.net) that was born out of my day job as an engineer in small business manufacturing.
The second is an AI engine for pulling structured data out of incoming email (either via IMAP on your email server or via SES). If you think of the engine that powers TripIt, they had to write about 10,000 different ingestors for each airline and hotel and travel booking site. With a structured output AI, the need to write specific ingestors goes away.
Honestly a little bit hesitant to say anything yet. There are a few more features to add, and a whole lot more work to be done to showcase just how cool it is. But the short version is, I'm working on a sort of meta-pico8, a game maker for WebGL2 2d pixel art games (e.g. 320x180 games like Animal Well) that runs in the browser, but one that's firstly collaborative, so that we can all build it together. And some of the coolest features are the based around that. For example, I got arbitrary imports of user code working in the browser, so all you have to do is create an account, add a JS file, and other people can import it as if it were a built-in module, and it just works. Plus the SDK I ended up making is simple, and the API is clean, and there's a few innovations in the GUI layer that I'm excited to share. I wish I could explain just how cool this is.
Interesting, I have been working on a similar project, albeit 320x240.
I also got some code-share and collaboration features working, but got a bit stuck on fonts. But I can appreciate your feeling of 'how cool this is'
I ground to a halt once I realised I had no barrier to entry, ie it could be cloned very easily. Always an issue with Web Development I guess. Plus I hate what modern browsers have become in recent years and not sure I want to target such a fast moving platform. I got burned once already with WebStart 'warning this app might do something scary' and certificate fiasco.
I thought about some native binaries, but I know I am kidding myself. I had an ios app that was pixel cloned within 6 months. But somehow a web app feels like publishing straight into public domain.
It's not just the web, native apps have always had free open source clones that technically render them useless, often just as good quality, yet they didn't go out of business. There are other considerations people make when deciding to use an app, including network effect, a strong community, sheer level of quality and passion from the developers, etc.
For fonts, I just went with a simple raster bitmap font and pixel grid storage format. Creating these limitations makes it easier for me and for developers and artists. I choose 320x180 because it fits the 16:9 perfectly, which would make full screen ideal on most monitors.
I am collecting IPs and other IOCs from some servers and honeypots that I have around and aggregating them with well known IPs and IOCs.
I would like to create a sort of search engine for that.

I'm working on a workflow automation tool that lets devs write workflows in simple yaml files, and then deploy them to the cloud _or_ on premise. Each workflow is a set of actions and a trigger that can transform data, make api calls, run AI models, or really anything (via docker!). Each step relies on the output of the last step, and the workflow framework is engineering to be declarative, testable, and versioned. Similar to GitHub actions, but for *anything*. Think webhook to slack, email to support ticket, nightly aws backup & restore, mirror a file each night, etc.
premises, not premise :-)
Thank you! Learned something new.

Is it possible to add an interactive challenge or two on the homepage prior to sign up? I think that would hook people in and make them want to sign up.
Good idea, currently I spin up a 2 neovim instances for each challenge, so can only spin up so many at once with my current setup. But, am moving to a kubernetes setup where I can scale up and down the number of neovim instances more reliably and will add that in then.
Ah, I assumed it would be an nvim JS clone running client side. Had you looked into that route?
I have, but all the JS vim clones are emulations of vim, and don't support all the vim motions (like copying from registers, etc). I honestly could do that and it would be easier, but doing it this way, also allows me to record the keystrokes directly from the neovim runtime.

Some music control using Wii balance boards thing: https://gitlab.com/TOGoS/SG-P27
So far this has means orchestrating a set of processes just to talk to bluetoothd, automatically connect to boards, guess which /dev/input/event* device each one is associated with, and start reading those and sending data somewhere over OSC. Every step of the process is about 10 times as difficult as I initially expected it would be, which is why, after months of work, I'm still putzing around with process orchestration instead of actually doing anything with music.
The bit of hair on this yak that I'm currently shaving is building a TUI library for Deno so that I can build a nice dashboard for keeping tabs on the state of all the different pieces.

There is a TUI library for Deno already, but it's kind of buggy and non-ergonomic for my brain.

I'm working on a desktop-based, performance- and privacy-first note-taking app that lets you quickly capture notes from any selected text using hotkeys.
I'm curious: what are your must-haves in a note-taking application?
I thought about doing something similar some time ago, because I never quite found the perfect note taking app for myself. There's a million ways how to do notes, and it feels like there's just as many different notes apps.
Eventually, I've settled with Obsidian because of its simplicity and extensibility. You can leave it with basic features and truly own your notes in a simple format (you can also put them into any cloud, as long as that cloud reaches your filesystem). It doesn't do everything just like I'd want to, but I've thought about just building another notes app that reads and writes to the same path your Obsidian notes are in, instead of trying to cover every possible editing feature like most big notes apps. Then I'd use different apps for different needs, with one place to store data.
Since you're focusing on privacy, have you considered using Obsidian? Is there anything particular you want to do differently?
Basically I want to build it with focus on speed and work efficiency from start. To not bias myself too much, I will refrain from doing too much market research. First of all I'm building this for myself, and I'm guessing it might translate into at least a tiny market share.
> I'm curious: what are your must-haves in a note-taking application?
Unlimited undos. Even if I deleted text a year ago, app must bring it back. Ideally something like git, with branches and auto-commits.
Great, thanks. This is already in my minimum requirements.

I’m working on a simple app that logs Karting activity and data. My son has been karting for a year or so, and there is so much data to collect - times, pressures, sprocket set up, track location, weather and more (about 30 datapoints a session)
Collecting the data helps with recording engine performance, tyre ages, best lap times but is also really useful for recalling how well each setup performed for future reference.
I’m deliberately doing this all in a very low-tech way as my son will be creating a more polished version for a school project. We’re front-running that a bit to give him a good dataset and explore various ideas.
On that note, they do Python in school. For the backend it will be SqlLite and Flask. Any suggestions for the front end tech? This will mostly be forms- and grids-based so nothing sophisticated needed, but some simple client-side logic (e.g. validation, geolocation, simple stop watch) would be good. Ideally this would be python as well. We could use WebAssembly but am wondering if there is a suitable framework that does the is out-of-the-box.

I'm actually really interested to see how other people are coding with LLMs. I guess this sort of thing is already happening on youtube and I could have searched it out but I did not. Will checkout your channel.
I am particularly interested in seeing how you handle the transition from LLMs doing great at one-shot prompts but then struggling as the scope of everything expands and you have to get smarter about breaking down problems.

I'm building an MVP for an "AI bedtime stories" app. The idea is that you just input the character names, a theme, and choose a voice (including the option to clone a parent's voice for narration). It generates a story and reads it out using TTS.
There are already a few services like this, but most don't support using a parent's voice, and very few can connect stories together into a continuous narrative based on previous ones. Also I would like to hold context for fairy tales kinda local. For example Polish folklore is different than British. Most common villains are different and it can be fun and educating problem to solve.
I'm mainly doing this as a learning project, but curious to see where it ends up.

I'm working on a running app. Mainly for me but others have expressed interest.
It's a performance analytics platform for runners who love to dive into the details after they've been for a run and to be able to accurately track their progress over time.
It's not like Strava because I'm not including any social elements, intitally. And not like trainingpeaks because it's focused on individuals as opposed to teams or coaches. Also the analytics and models I offer are peronalised as opposed to one-size-fits-all. It's also running only. No cycling or anything else.
Ideal target market would be fairly decent amateur runners (e.g. sub 3 hour marathoners) who already know quite a bit about training but don't have a coach and are not good enough to be pro and have a full team doing this stuff for them. The pros have awesome tools but sadly most are not available for us mere mortals BUT I can build some of them! Example features:
1. Personalised "adjusted speed" models. The strava GAP model doesn't fit very well for me and many others, so I've made my own personalised model which gets updated each week. If you get better/worse at running up hills then model adjustments take that into account. The idea is not to provide a physiological correct model but more a performance based one.
2. I'm trying to do the same for surface types, heat and humidity as well. Of course these models are not personalised. I'll get to wind later on as it's much more complicated than the former. The idea is to have an accurate representation of "effort pace", which you can use as an input to performance models.
3. Using adjused pace data I will offer a pace/duration model to estimate critical speed/LT1/LT2/VO2max and this model forms the basis of tracking progress over time. Clearly most training wont be all out efforts, so I also estimate race performances based upon current fitness as well. E.g. if you ran X speed for Y time at a sub maximal effort then you can estimate what a maximal effort would be based upon the remaining aerobic and anaerobic power. From reading sports science literure, this is the most advanced way to track performance at the moment. The actual model I use is called an omniduration model.
4. I also have build some other models, e.g. Daniels running formula, which can be used but I don't find them to be as useful as the omniduration model.
5. I'm also trying to model how a workout or training session will effect your fitness. Where it's base/aerobic, threshold, VO2max or an anaerobic effect. Then, the idea would be to look at future training performance to assess whether the model was correct. You can then assess which types of training you respnd best to as well as which types of sessions you need to get the performance gains you need for your next race.
6. Specific race time predictor. Most platforms offer a single figure prediction for a distance but I want to offer specific race perdictions which take the course and weather into account. The model will give you splits taking all this into account.
7. Cohort adjusted performance models. How are you tracking against people your age? But more importantly, how are you tracking against people doing a similar volume and type of training to you? Are you improving at a similar rate?
There's a tonne of other stuff I can add but I'm going to keep it simple and focus on performance modelling for now because no-one seems to offer any decent tools around this at the moment.
If anyone found this interesting then I'd love to hear any feedback - let me know. Cheers!

We're building electric batteries for e-bikes that are repairable and fireproof!
https://gouach.com
Are there standardized e-bike battery formats or are you hoping to partner with e-bike manufacturers?
There's no standardized format, but:
- we ship with a mounting piece that is easy to put on any bike frame to mount our battery
- our app and communication protocol is open-source, and we provide code for compatibility with the major bike controllers, meaning we're compatible with 90% of the e-bikes!
so in practice we're the perfect battery for e-bike enthusiast who want to change their battery to a repairable and fireproof one
and we also do B2B deals with some brands who want custom design etc
but basically if you are running Bafang / Shimano / Bosch controllers, it will work with our battery

I've recently added autobatching to my SFML fork (https://github.com/vittorioromeo/VRSFML/tree/bubble_idle). Drawing multiple objects that use the same RenderStates will now be automatically coalesced into a single draw call, for example:
for (int i = 0; i < 10000; ++i) renderWindow.draw(sf::Sprite{/* ... */});
Upstream SFML: - 10000 draw calls (!) - My fork: 1 draw call
This (opinionated) fork of SFML also supports many other changes:
- Modern OpenGL and first-class support for Emscripten - Batching system to render 500k+ objects in one draw call - New audio API supporting multiple simultaneous devices - Enhanced API safety at compile-time - Flexible design approach over strict OOP principles - Built-in SFML::ImGui module - Lightning fast compilation time - Minimal run-time debug mode overhead - Uses SDL3 instead of bespoke platform-dependent code
It is temporarily named VRSFML (https://github.com/vittorioromeo/VRSFML) until I officially release it.
You can read about the library and its design principles in this article: https://www.vittorioromeo.com/index/blog/vrsfml.html
You can read about the batching system in this article: https://www.vittorioromeo.com/index/blog/vrsfml2.html
You can find the source code here: https://github.com/vittorioromeo/VRSFML
You can try out the interactive demos online in your browser here: https://vittorioromeo.github.io/VRSFML_HTML5_Examples/
The target audience is mostly developers familiar with SFML who are looking for a library very similar in style but offering more power and flexibility. Upstream SFML remains more suitable for complete beginners.
I have used this fork to create and release my second commercial game, BubbleByte. It's open-source (https://github.com/vittorioromeo/VRSFML/tree/bubble_idle) and available now on Steam: https://store.steampowered.com/app/3499760/BubbleByte/
BubbleByte is a laid-back incremental game that mixes clicker, idle, automation, and a hint of tower defense, all inspired by my cat Byte’s fascination with soap bubbles.

Browsing jobs nearby and watching old movies to gather ideas on what to do next, getting as many documents as possible and making copies of them, and updating eye prescriptions and dog and cat shots.
streamlining the house to save money and sanity when we both start working and/or going to school
and starting to seriously start using a simple phone book
and mentally preparing for rent to go up or a car issue by causing controlled chaos and finding new ways to calm down as a family with as little money and energy as possible
by watching old movies from movie Madness, we're gaining insights into the origins of the items we use today. The futuristic visions of the sci-fi pioneers are serving as a Wikipedia of sorts, helping us break free from generational curses and regain a sense of control.
since it helps because, understandably, not being employed makes us feel ultra vulnerable, and that is not only normal but what the tech cults thrived on, but it is insane to take out our nerves on each other constantly and or/the animals. And to be on mass amounts of pharmaceuticals or heavy drinking is no walk in the park either in terms of ROI on keeping the embers of love and growing old, but Gandalf/Sith Lord grandaughter redemption President signed letter die at 102 years old happy clearly an attainable trajectory
As my upcoming birthday approaches, I can't help but feel that it might be the most special one yet. despite the tears, anger, and losses, I feel some reality based it is gonna be hakuna Matata SophiaG20
while zero jobs I see and know about are for me, I'm content knowing that my brain's imagination, creativity, and curiosity machine is still growing at 36. And feeling bad ass
read an article from Wired about Patricia Moore and honestly thinking about how Empathy and how the need for tech to let the ones like my mom freaking out and having plastic surgery and going overboard on Facebook and freaking out over menopause because she's 20 years older than when most of the women in our direct family died
I am inspired to find a real way to a home we actually own, a home we feel we have worked and earned. I am also motivated to soften the blows that life inevitably brings, such as the possibilities of allergies due to eventual menopause or the loss of a loved one. I see myself working for me and the current and women who are girls right now.
So tech will be more on their side not telling them to worry about the outside while the inside rots or worse something is off and no one cares or listens.
I am navigating these challenges on newly Medicare (newly disabled) and still finding ways to go back to the default feeling of being the fierce queen that I had when I was 5 years old with my grandpa.
but also letting the mind wonder so that others will be the fierce queens that they are because that is how my grandfather and his team made things after being POW in the holocaust, and he would want it for me and my badass mothers. Not to follow in what he did but find my own path for my own tribes with our own ways.
It feels like a rebirth of some kind for the trillionth time, but this time sober with a family (who loves me and I chose) and less toxic companies in my subscriptions or emails (because I nuked entirely the old Ecosystems which is making taxes pretty astonishing) like the intro to Hackers. Still, I killed myself online on purpose, crying and laughing, saying: don't threaten me with a good time On a Pixel and Samsung phone and Apple phone while Microsoft and all of them were like, NOOOOOOOOOOO!! ~ 20th Nov 2024, and it feels like that was a sinister evil evil Cult, but damn, reality tastes crisp, and there is more to chop to make it to 102. With the vibes still fresh from the interesting dozens on dozens of 100+ year-olds I took care of when I was 14-22 years old in Alaska and coming to terms my grandpa who I was TWO peas in a pod was one of the architects of DARPA and architects of NASA, and that is fricken cool
but now it is time to start pulling in the resources for this growing family instead of being salty about wasted time in Cults moving forward, like my father and grandfather's visionaries. I am finding a way forward by choosing not and withholding this visionary raw energy from DARPA and NASA because, in the end, all the promises they gave my grandpa did not happen. at. all.
And being cool with the fact that I will learn how to live life without ADHD meds even though it has been an option since I was 5 years old, but like the olds who came off Prozac recently, I want to start life anew without that stuff. 15 years is enough to say that shit wont get me to 102 years old comfortably with the family and loved ones knowing I'll be fine if 5-20 terrible terrible things happen back to back again.
