A comercial database application

Between 1999 and 2002, I put the equivalent of about 1¹/₂ years of fulltime work into a desktop database application written in C++ and Perl. This is currently the largest contribution I've ever made to a single project. I did about ³/₄ of the design and half of the implementation.

a language comparison using a simple tic-tac-toe game with a command-line interface and an alpha-beta player; I used it to learn several new languages in the second half of 2006. It's written in Common Lisp, OCaml, Haskell, Perl, Python, Ruby, C, and C++. There's also an HTML/CSS/Javascript front-end and some Ruby-on-Rails code for a web-based version.
