I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/ https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/ https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun.
