#953Continuing to work on Kan, an offline Kanban board which operates on plain text files in your repo, so you can just commit the entire board into Git!
I'm finding it really good for agentic work these days as, using the kan CLI, agents do really well with it for tracking work and leveraging the board. I'm using it for all my projects these days.

#954I'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 ;)

#955I'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

#956My own WYSIWYG Markdown editor for mac, iPhone and iPad.
It's mostly Obsidian compatible.
I've launched it less than 2 month ago and decent amount of people are using it(2K downloads), so now I'm working a lot on making it better.

#957Working 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.

#958I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control. Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI…
Famously Norwegian cows “picking” stocks by shitting in marked grid did as well as professional stock brokers and much better than astrologers!
But is that before or after fees? Does each fund manager take more or less than the cow's dollar equivalent in pasture?

#959I 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!
