I've spent the last months building a videogame: Cardume [1], its a pvp game where 2 players battle using a swarm of thousands of cells. It uses Reynold's boids, Couzin flocking behaviors and diffuse fields to generate a mini ecological simulation each game. The sim is pretty well optimized, handling 12k agents at 60fps in a medium hardware machine. It also has some pretty cool visuals. Any feedback appreciated, the…

#463The main point is adding relationships between the entries, as that's the bread and butter of Obsidian.

#464I was an experienced game designer and producer (mostly RTS and narrative RPG). Some years ago, my career was derailed by major health developments. Since then, I haven't been able to work as I once did. I didn't expect I'd be able to meaningfully contribute to a game again. Earlier this year, a colleague encouraged me to experiment with Claude Code. So now I have a little game project. :) Being unfamiliar with genAI…

#469I wrote it because I was too lazy to learn how to use KiCad's layout features properly, and thought 'how hard can it be?'. Several months later, I had this.
It's not intended to compete with Altium etc. but it certainly produces compact, valid and fully design-rule-compliant boards with much less work that doing it myself or using one of the low-cost remote labour platforms.
It uses constraint logic programming to solve the hard parts of the problem. Hierarchical decomposition of the circuit design helps reduce combinatorial explosion, which was a show-stopper for early versions of the system. Current indications are that I may be able to scale it further in the longer term to deal with more complex design scenarios and larger boards, without hitting the exponential cliff.
