Thursday night I discovered Project Euler, a site full of math puzzles that can be solved algorithmically in under a minute each. Since then, I’ve solved the first 30-odd of them. Friday night Marcus and I sat down to solve the week’s new problem as it appeared online (we came in among the first 25 or so).
These are great fun. I think about them quite a lot as a background brain task, and I’m rediscovering how cool math problems can be. To make it a coding excercise, I’m trying too write them all in Lua and not in C, and as a result I feel that I’m getting a lot more confident in everyday Lua hacking.
