Intuitive Information
Information theory, drawn instead of derived.
Error-correcting codes, explained with pictures: a room full of people, a magic trick, and a hypercube. If you can tell even from odd and walk along the edges of a cube, you can follow every step.

Catching a cheater with a cube: Hamming codes on the hypercube (part 1)
Seven people, one cheater, and a magician who always points at the right one. The trick is a Hamming code, and the picture behind it is a cube with one corner missing.
Catching three cheaters with a tesseract: Reed–Muller codes on the hypercube (part 2)
Same tesseract, one level deeper. Put parity on the squares as well as the cubes, and the group catches up to three cheaters at once: the Reed–Muller code behind my 2013 ECC-HyperCube.

Written by Tue Bui, a software engineer. The blog started in 2013 with part 1; part 2 was lost for years and rebuilt in 2026 from the code that followed it. More posts to come.
