I've been working on a voxel game engine called Bonsai for ~10 years. Probably the most interesting thing about it at the moment is the editor. The world, and most things in it, are represented as collections of SDFs. More accurately, they're density fields, but, potato-tomato. Bonsai has undergone a large rewrite over the last couple years that's nearing completion. A world edit is defined as a bunch of SDF paramete…

Looks cool. What would you say its defining features are? What makes it different than Minecraft? Seems like its probably more performant. Whats the license situation. I see your own license which sounds maximally permissive but written by you. Is that just how it works? I can do whatever I want with that license? It doesnt need to be a “real” license? Maybe your bonsai logo should come from your voxel engine instead…

Hey, thanks for the kind words!

I'd say the defining feature is the editor and terrain generation system. At the moment it's not well documented, but once the big rewrite I've been working on has settled I plan to take some time to make tutorial materials.

As far as the license goes, I chose WTFPL originally because I figured it would dissuade 'real' companies (with legal teams) from using it. I've since thought about changing the license to something permissive that might play nice with legal teams, like MIT. You can do whatever the fuck you want; it says so right in the license ;) I'd actually love it if people used it. My intent now is to keep the engine open source, and build games with it in closed-source repos.

You're right, I should change the logo. It's on the todo list .. it's just a really long list ;)

I'm working on a programming language for agents to write and humans to read. Think Lean4 but built for software engineering. It's dependently typed based on Observational Type Theory. A few key differences from Lean4: 1. Constructivist rather than propositional logic, so propositions can be true or false or unknown. 2. Compiler which targets the Linux ABI (in progress). An interpreter exists and acts as an oracle fo…

Awesome! doing similar things

Working on two routing / proxying projects.

grpc-comparator proxies between an original service, and it's replacement calculating timing and any deltas in responses. You instruct it which response attributes you care about.

edge-flipt uses/abuses Istio ext_authz to inject headers derived from flipt snapshot evaluations for downstream consumption, including VirtualService route selection.

I am working on a cyberpunk multiplayer, shared, persistent world which runs completely in a terminal, and you can access just by typing "vibeworld" in the terminal( https://github.com/SorBalda/vibeworld ). The idea is that developers and scientists can meet each other in the terminal in a funny way at 3 am while working. There is a place in the moon where you can "scream" against your last LLM session and everybody…

Beautiful!

I've been working on a Real-Time Communication system, and right now I'm focusing on the frontend side of it. The UI/UX gives me a better understanding of how important user experience is when building a client-side application.

I now have a good idea of how features like chat roasters, read receipts, audio/video calls, voice messages, etc. work in WhatsApp and similar applications. The implementation might differ from one application to another, but the core fundamentals remain largely the same.

https://shopspec.io/ ShopSpec is a deterministic parametric furniture generator (bookshelves, cabinets, shop carts, leg-and-rail frames, multi-carcass composites) that encodes real woodworking intelligence and outputs shop-ready artifacts. Most recently, introduced the concept of value engineering by sweeping across dimensions to batch evaluate candidates that ranks based on sheet purchases. Also have in beta an MCP…

Hi there! I'm a woodworker and love seeing new woodworking software! Thank you for making this.

I could tell from the layout screenshots, but one thing to make sure is that you are accounting for the size of the kerf. Being able to set a different kerf size for different cuts would be ideal as your rip vs crosscut are often different blades.

Also, one of the more daunting parts of casework for me is sorting out exactly how undermount slides go. I would highlight any help your tool does with raising confidence in getting those installed. Even having an undermount installation tool separate from the spec work I think could be useful.
