This repo contains a lot of random play: bits of coding tutorials, exploratory programming to learn a new technique, incomplete stuff that help me clarify my thinking, that kind of thing. There's a lot of junk in here, but part of the point of open source is sharing our random code as well as our polished projects. :-)
For example, when I wanted to play with Python C-extensions or Fortran extensions, the simple example code I wrote ended up in this repo. But the real work probably didn't.
The Euler directory contains some solutions to Project Euler problems, mostly in Python or Fortran.
