I benchmarked which language works best with Claude Code. Ruby, Python, and JavaScript came out cheapest,
fastest, and most stable!

A Ray Tracer Written in C Macros -- IOCCC 2024 โ€œPatient Pointillismโ€
A Ray Tracer Written in C Macros -- IOCCC 2024 โ€œPatient Pointillismโ€ YouTube video by Yusuke Endoh

I also received another IOCCC award for a ray tracer written entirely in C macros.

One preprocessing pass renders one pixel, so generating a 256ร—256 image takes 65,536 passes... and about 3 hours.

Rotating Rigid Body Simulation -- IOCCC 2024 "Solid Body Physics" YouTube video by Yusuke Endoh

I won IOCCC 2024! Here's a 2.5 KB rigid body simulator written in C.

It can simulate the Tippe Top, a top that flips while spinning.

Minesweeper spoiled by AI This Minesweeper AI does the brain-testing part for you. You do the luck-testing part.

I created Minesweeper for the AI age. AI opens cells that are inferred to be mine-free. Humans must open the other (potentially dangerous) cells on intuition.
The fun, simple tasks are taken away by AI. The job for humans is to take responsibility ๐Ÿ™‚
