- GuardUp - swordfighting studio where I taught fencing and sport sword
- Random Hall - my undergrad dorm
- MySQL Turing Machine in a single SQL statement (Setup).
The stored procedure is an unwound version of the statement. The statement could probably be compressed further, but I haven't bothered.
- Therac-25 curses simulator (therac.c).
The Therac-25 was a radiation machine that killed 7 people due to
software bugs (mostly a concurrency problem). The paper on it by
Nancy Leveson is eye-opening. I wrote the simulator as part of an
April Fool's joke I played on the class that reads the paper.
