  this is something that I've been struggling with – there are now a half-dozen new CAD kernels in Rust, all with the same perfectly polished websites and bold claims about performance, test coverage, and quality (from https://jepsen.io/analyses/particledb-1.1.4)

  It's a weird feeling to get an email which - asks questions about one of your open-source projects - references specific files in the repo - those files are definitely not in the project Are you from a parallel universe? Do they have any cool Fanta or Kit-Kat flavors over there?

  I've just announced my new (blazing-fast) kernel for implicit surfaces: https://mattkeeter.com/projects/fidget It's got something for everyone: Cool graphs! Multithreaded WebAssembly! Terrible mesh topology! JIT compilers! After three years, I'm excited to finally show it off to a wider audience 😎
