There was once a shortest useful program contest, his entry was 2 bytes long[1]
When he lost the source to a program he wrote, he created ReSource, a disassembler[2] that got forked a few times over and eventually gave us the NSA's GHIDRA
He was stuck at home because of a snow storm, and with Randy Suess, created one of the first BBS systems, and open sourced it.[3]
