I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy. https://github.com/scallyw4g/bonsai I also wrote a metaprogramming…

That is so neat. I built something a little bit like this for a simulator of a 3D portal mill. Trying it on real wood got expensive fast so for debugging runs and trials of designs I would run a simulation where the toolbit would hack out the shape out of a three dimensional array of voxels. This was then displayed using a very simple engine built with PyGame. I got a lot of use out of that and it saved days (and a s…

That's an interesting application! I'm excited to see where these kinds of projects go now that we have so much computing power.

Wow the voxel engine work is beautiful! Impressive work man

Thank you! It's definitely been a labour of love

Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

A couple of suggestions:

The completed entry should include the date of the test results, so currency can be judged,

Ideally the completed entry should contain a scan of the full test report from each of the accredited laboratories.

https://spanara.app Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI. I am currently working on a new mode that is more like what played walking around: a f…

Seems like a really small dictionary. Many/most of my guesses (and Gemini's) don't work.

I am creating a webapp to let screenwriters collaborate when writing their scripts.

I have several friends in this industry and their tooling is either expensive, not localized for their market or straight away bad (I've seen terrible dataloss).

I got some inspiration from linear and am building it on top of ruby on rails with CRDTs.

https://snapreceipts.fyi/ Upload receipt photos, assign who got what, and easily calculate splits.

Idea looks interesting if done well. I believe you should, on your landing page, show an example : - mini photo of a bill - what it generated.

So people get it right away
