Hey HN, I wanted to get more familiar with C programming, *nix socket programming and C compilation, so I wrote this "web" ""server"". It's running on a tiny SBC in my office, and there's as little as possible between you and it.Happy for you to try and break it, hopefully with something more interesting than a DoS though :) Please let me know if you find any issues.
Other tips: I still had issues going too granular with GOAP actions at the start, so I recommend keeping your actions as coarse as possible. It's still a tool that you use with your AI designer hat on, it doesn't do everything on its own. But the power of being able to throw in a new goal, maybe one new action, and have the existing actions solve all the other prerequisites, is amazing. Defining world properties and states is a muuuuuuch lower mental load than using utilities for actions.
I wrote it all with performance in mind, and it seems to run fine. Basically lots of caching (each world property is only evaluated once per AI per tick then re-used, shared values are cached for all then re-used, etc); eliminating invalid paths early; and searching backwards from the goal instead of forwards from the current world state. I test with 4 AI players on an old i3 laptop processor from ~2016 without issue.

Hey HN, I'm working on a game where you throw stacks of your own team-mates in first-person, in various gamemodes. I tried a few different approaches for player AI, but ended up settling on Utility for "what to do" and GOAP (Goal Oriented Action Programming) for "how to do it". Each of these (Utility AI and GOAP AI) are worth watching videos on, they're very cool.Utility AI was popularised by...
- This page is running directly on the Pico W in the stream, using microdot (but proxied out via cloudflare tunnel).- There's a buzzer that plays a sound as well but the stream has no audio.- There's a Pi Zero 2 W with a Camera Module 3 streaming the video. Streaming low latency video is painful. I tried mjpeg, Nginx+HLS/DASH, YouTube and Twitch. Twitch is definitely the easiest and...
Stateless tech is great fun. If it fails you rebuild it and everything is (mostly) okay again. Frontend and app tier containers, network devices, even compute hosts. There's lots of posts about these.But state (and loss of) can be nightmarish and we mostly want to avoid it. We outsource database hosting to cloud providers, avoid touching SANs, hand-wave away schema change and rollback...
Another of the author's projects sits solidly between awesome and terrifying: https://github.com/ShaunLawrie/PwshRayTracer
> A very slow raytracer in PowerShell that has been optimised from ~100 camera rays traced per second to 4000 rays per second on a 4GHz 6 core CPU with a few tricks
> Because I've been learning a bit of serverless stuff I was curious as to how much faster I could run this using PowerShell in a webscale™ setup by distributing the processing over as many concurrently running lambdas as I could get in my AWS account:
> By using Lambda with large memory sizes to get more cores I had >250,000 camera rays per second (~62x my laptop speed) but I managed to rack up a $200 bill over a couple of bad runs
A tip that people on HN will probably enjoy: add --disable-smooth-scrolling to your shortcut to make scrolling more responsive.
It took a few times to stick, but I've now fallen in love with Obsidian and am migrating everything except a large project's task-tracking system to it. The WYSIWYG editor, fully nested hierarchy and fast full-text search is fantastic and makes it better for my personal documentation.
I'm extending my Trello backup project to make the migration easier. Take a look if you're considering the same move. https://github.com/GSGBen/t2md
