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…

pretty damn cool. SDFs are the best. I've been playing around with an idea around this on the weekends.

Such a cool primitive!

This is going to seem boring compared to others, but I'm working on learning enough AI Systems Engineering, in order to get to the point where I can direct and orchestrate AI agents for multiple hours/days and building a harness to help with that. Hopefully this will help my job security, unless the AI goes enough AGI to not need software engineers anymore. It's also really interesting and fun.

Working on a Splitwise alternative: https://peanutsplit.com Fully Open source, free forever of course.

Looks really nice. Thanks. Love that, there is no signup required.

A blockchain that uses neither hashing nor stake for security. (And not authority.) I will post here when done. Although, I will do so with some trepidation, because I know how much antipathy there is here for blockchains.

https://fantasybook.bet A next-gen fantasy sports platform where managers buy/sell player shares like the stock market. Not just free-agent budget (FAB), we have a full order book implementation. You can create private leagues or join a public one, and recently I added Venture mode where you can invest without a league to enjoy watching your smart decisions pay dividends. Fantasybook is for entertainment only as of now. I'm very proud of the latest UI revision, too. This has been a big project for a solo dev and I'm trying to learn marketing. Check it out!

I'm building https://uscodex.org. In a nutshell, the goal is to collect all US federal law in version control, and cross-link any references between different sections. Currently I have the US Code, CFR, ~30 years of public laws and congressional bills and 25 years of executive orders.

Actually using raw git repos as the main data store which has worked out great since the US Code changes very little between new releases and so it compresses very well. Also makes it easy to generate diffs of sections: https://uscodex.org/usc/d/119-100/119-102not101/16/2201

I always wondered why Splitwise is the go-to when it's a huge pile of crap app with stupid paid features for such a simple concept.

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…

Awesome, is there a way to use metric system on it?
