    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.

    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!

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

    Cool. This is how I imagine the ants were programmed by the spiders in Children of Time.

      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?

    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.

    • lightamulet 3 hours ago

      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

    What's with "artesenal"? Is this a joke that I don't understand or a surprising way to write "artisanal"?

    • lightamulet 3 hours ago

      the answer is my editor doesn't have spellcheck and i apparently don't know english as well as i thought, fixing :')

  • 4b11b4 13 hours ago

    Wait what this is the best reason to write a bunch of assembly AND learn about ants?

    • armandhammer10 13 hours ago

      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 ;)

        > ants are smarter than they look.

        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.

        [1] Not a euphemism for a lovely garden in that case, it was literally about a square yard of concrete behind the mid-terrace I was renting.

        > 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.

      • lukan 10 hours ago

        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)

  • ivanjermakov 4 hours ago

    All dark themes are too low contrast. Give me pure white (including comments) on pure black please.

    • lightamulet 3 hours ago

      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!

      • ivanjermakov 2 hours ago

        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).

  • nurettin 13 hours ago

    This is a balancing act between collectors and explorers. There is probably some optimized number. Likely targeted at beginners.

    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

    • tgsovlerkhgsel 5 hours ago

      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.

      • boutell 2 hours ago

        Sure, hiring is expensive, but firing is really expensive! I salute your efforts to get it right on the first try.

    • armandhammer10 14 hours ago

      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.

      • dr_kiszonka 13 hours ago

        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.

      • nylonstrung 9 hours ago

        Appreciate this, very cool of you to do that

    • AndrewKemendo 4 hours ago

      Way less than you would pay for a recruiter

      they usually ask for a non trivial percentage of the first year salary
