That's really cute, it reminds me that Will Wright (creator of The Sims) has referenced this book "The Ants", by Bert Holldobler in multiple occasions as a key inspiration for his games (and in particular SimAnt) and systems thinking. Did you come across that during your research phase or had you not heard about it? I haven't read it yet, but maybe someday I'll get around to it.
Hey, I'm the one who built this particular challenge!
I had no clue, but thanks for the book lead! It didn't come up directly, but SimCity 2000 and especially SimCity 4 had a huge impact on me growing up / I still spin up SimCity 4 from time to time, so I imagine there's a massive indirect influence haha.
This is actually all built in nextjs/react, though the initial sketches of the sim had no visualization and were just running in my terminal using bunjs
Will Wright gave at least one great lecture at SIGGRAPH. Wonderful thinker and communicator. #ACM plz unlock this culture.
Ants have fascinated me from a young age, I’d construct a viewing platform so I could watch the hive at work.
My favorite were the carpenter ants, so smart. It feels like they have a theory of mind. I didn’t hurt them, but if you disturbe their nest under a board, the efficiency and expediency they would exhibit while collecting their young was fascinating.
*edit, I meant to ask if you had any other book recommendations?
Well, I'm currently reading through "Designing Virtual Worlds" by Richard Bartle. He's known for being one of the creators of MUD (multi-user dungeon). I'm not far along enough to make a judgement on the quality of the contents, but I keep seeing the book title pop up everywhere so it seems important.
Speaking of SimAnt, I soon discovered the bug that by moving into the top corner, the black ants would conquer all squares with no intervention from that one sideways and downwards and too easily win the game.
Still, it was fun just messing around with the ants, watching the trails, and chasing spiders by calling forth all ants.
In the reference material under ARITHMETIC, it shows `AND r1 0xFF` as valid. However, actually using that code always produces zero regardless of what is in r1. My experiment concluded that only decimal inputs are supported, and hexadecimal are not, but the reference doesn't say that, and the editor doesn't flag the hexadecimal inputs as an error. Perhaps the reference material should be updated to simply show "255" instead of "0xFF".
Here is code to reproduce:
; ==================================================
; Bug Report:
; AND operation returns 0 when give a hex argument
;
; Expected behavior:
; (1 AND 0xF) should either equal 1 or the
; line should be flagged as an error.
;
; Actual behavior:
; (1 AND 0xF) equals 0 and does not flag error.
; ==================================================
.alias input r0
.alias output_using_hex r1
.alias output_using_dec r2
main:
; Pick any number only using bits 0xF
SET input 1
; Test using hex
SET output_using_hex input
AND output_using_hex 0xF ; no error raised
; Test using decimal
SET output_using_dec input
AND output_using_dec 15 ; (15 == 0xF)
PICKUP ; end the tick, so registers are stable
; Registers at this tick boundary:
; input: 1
; output_using_hex: 0 (incorrect)
; output_using_dec: 1 (correct)

My "hello world" for a new stack is always a version of Worm. Somewhere between Life and your Swarm, Worm wanders around looking for food and water, trying to avoid birds and other issues. Each round the worm survives it grows by a segment. If it doesn't get food or water, it is reduced a segment. And so on. Your Swarm is a few levels up from my iterations, totally inspirational! Thanks!
I've been working on a surprisingly similar project for the last week: plants grow cells on a grid by executing a raw chunk of memory according to a simple instruction set. I'm aiming more for an evolution simulator, where each plant gets a 1kb brain that is randomized a little when a new plant is spawned.
Most plants right now settle into a simple goto loop that places the requisite cells to survive and then spam seeds until they die. I have seen some interesting variety in body plans emerge where plants sort into discrete species regionally. I'm hoping to eventually get decision making to emerge organically. If things go well this system is theoretically capable of sexual selection (and maybe fisherian runaway) but that's a pipe dream right now.
i think this took me (1 person) like 40 hours max? all built in the last week, though i spent more time than i should have on it haha. quite ai-assisted, that's how most of the layout like the editor, player controls, even eval server got set up.
i spent way too much time on things like the language itself, map generation, and figuring how to only recompute the sim on material code changes vs whitespace and comments (it assembles to "bytecode" with debouncing! and the sim component takes the bytecode as a prop).
we'll see if good ROI, we definitely intend to run more of these types of challenges in the future, so much of this work won't go to waste
But in all seriousness, ants are smarter than they look. They operate as a collective. Just in the same way that assembly needs to operate collectively to get the best output.
They're more closely linked than they appear from the outside ;)
Many moons ago I had a big pot of rhubarb in my back yard¹ and was initially irritated by the appearance of ants and aphids, until I took a moment to watch them and realise that the ants were bringing in the aphids and tending to them. The buggers were farming. The ants can't digest the leaves of the rhubarb, but the aphids can and excrete a sugary by-product that the ants “milk” from them. It is a fascinating bit of nature to read into. They even defend the aphids from predators and so forth, so it isn't a bad life for them either.

> But in all seriousness, ants are smarter than they look.
I'd argue the opposite, ants are dumber than they look. You look at a random ant stack in the forest and it looks like they're smart, but that's only when they're "controlled" by the collective, individual ants themselves are pretty dumb in the end, but it's hard to see as typically we always see them around/in their stacks in nature.
As a collective, yes. If you look at individuals, they often go in circles and act really dumb. But for the colony it still works out, bigger brains would cost too much energy I suppose and simple algorithms work. (I often watched real ants while and my head translated their behavior to simple algorithms)

The prizes (Maui trip, second/third prizes, swag kits, shipping for the swag kits) probably cost around $20k in total.
Assuming an engineer costs $200k/year, 200 effective working days per year, that's 1k/day. Developing the contest (from the idea to building the rules to building the site to playtesting) likely cost more than 20 eng-days, making it the biggest cost.
Hiring is expensive. If it takes 30 minutes to screen one candidate for suitability for the "real" interview and 5h to do a "real" interview (including evaluation etc.), 5 screenings for one interview-worthy candidate and 5 interviews for one hire (I suspect the real factors might be closer to 10), that's 12.5h of screening and 25h of interviewing per hire.

This is exceptionally beautiful. What did you use to build it? Vanilla JS?

what is this? assembly for ants?
It's assembly for people who can code good.. and can do other things good too.
It needs to be at least three times this size!
just be glad that ants are ambiturners
ant-ssembly to be precise
So hot right now
Cool. This is how I imagine the ants were programmed by the spiders in Children of Time.
The disclosure route is cut off at the bottom: https://dev.moment.com/disclosures
I cannot scroll to the Governing Law section
This sounds a lot like a task of 2004 ICFPC Programming contest: ants, pheromone trails, only local vision, etc: https://web.archive.org/web/20060709155354/http://www.cis.up...
I can't see the rules of this challenge, but it sounds really darn close.
I wish I could read dark-mode but my eyes somehow cannot handle it (not just on that website, in general).
there is a `theme set` command
Did website break?
I only see "MOMENT" and "All systems nominal"
Incredible low contrast font color in use there. Looks like about 0x002000 on pure black (per Mk-1 eyeball).
What possesses people to go for these barely perceptible color schemes?
.. a few minutes later ..
Ok, the crazy low contrast was on the initial landing page. Things have somewhat improved after prodding somewhat blindly at it.
I'll let the question stand though, bc why do that for what's going to be people's first impression?
try pressing any key or clicking around :)
I think I read a Daniel Suarez book about this once.

This is a balancing act between collectors and explorers. There is probably some optimized number. Likely targeted at beginners.
So.... a sort of modern Corewar?
Is it possible to reset the source once you've started modifying it?
Orwell would suggest you use the word normal.
The amount of effort put into this tool...just for hiring to your exact shop? I cannot imagine that's a good return on investment?

There's also a trip to Hawaii in it for you.
People like doing cool stuff
Wait what this is the best reason to write a bunch of assembly AND learn about ants?
And (potentially) go to Hawaii!
But in all seriousness, ants are smarter than they look. They operate as a collective. Just in the same way that assembly needs to operate collectively to get the best output.
They're more closely linked than they appear from the outside ;)

Someone else who has read Godel, Escher, Bach by Hofstadter?
Excellent book cheers
This is really quite cool.
What's with "artesenal"? Is this a joke that I don't understand or a surprising way to write "artisanal"?
the answer is my editor doesn't have spellcheck and i apparently don't know english as well as i thought, fixing :')
All dark themes are too low contrast. Give me pure white (including comments) on pure black please.
on the home page (dev.moment.com) you can type `theme -h` and then `theme set [name]` to change the color scheme, which carries forward to the sim!
Yes. I checked every theme and all dark themes are too low contrast. Pacman is good but comments are barely readable (gray on dark gray).
Am I being dumb? I was expecting to see ability to look at and run some canned sim

Nice way of hiring but is it really worth it to give the public a trip to Maui (kinda expensive these days)
Does it really reveal that much talent to make it worth the money?
Just curious
The prizes (Maui trip, second/third prizes, swag kits, shipping for the swag kits) probably cost around $20k in total.

Sure, hiring is expensive, but firing is really expensive! I salute your efforts to get it right on the first try.
It's less about the money. It's about giving people a chance to do something fun / show off their skills and get rewarded for it.
Plus, Hawaii is awesome.
I think it is a fun contest! As for recruitment, it suggests to me you are looking for people with no kids, and possibly young people.
Appreciate this, very cool of you to do that
Way less than you would pay for a recruiter
they usually ask for a non trivial percentage of the first year salary
