he wrote a very interesting c extension language at autodesk called atlast, wrote a diet guide that's made the front page of hacker news countless times, was doing things with neural networks on the commodore 64, had libraries to help make c safe, put some very cool recipes on his website, and also founded some cad company i guess
copycat but not clone of a just-short-of-modular synthesizer before that was a thing (the project he was clean-room reimplementing was by harry pyle, designer of the intel 8008 who he knew personally): https://fourmilab.ch/webtools/MindGrenade/
insanely massive collection of multi-language benchmark results (including an implementation of a raytracer in a range of languages so large it includes algol-60, pl/i & raku)
