Please enjoy my open source projects!

My recent Open Source projects are now maintained on my github account so please check that out!

All of the source code for my recent book projects is on github.

I also have projects in a variety of languages: Haskell, Clojure, JavaScript, Java, Common Lisp, and Smalltalk.

While I wrote these projects for my own use I hope that you find some of them useful.
