WeScheme

In the Summer of 2009, I authored WeScheme with Danny Yoo, Shriram Krishnamurthi, and Emmanuel Schanzer. WeScheme provides a browser based Scheme IDE. At the heart of WeScheme is moby-scheme, a self-hosting Scheme-to-JavaScript compiler. The backend of WeScheme runs on Google App Engine using the Java API, while the frontend is mostly jQuery. The service supports authentication using Google credentials. Code exists for a parallel authentication system. moby-scheme is under active development. The source is available.

Haskell + CouchDB

Arjun Guha and I authored Haskell bindings for CouchDB. The bindings are available here on Hackage. Andrew U. Frank has graciously provided a tutorial.

TreeStructures

TreeStructures is a collection of heaps and search trees for Haskell. The package attempts to offer an alternative to Data.Map. The source code is available. I wrote large portions of it while on an airplane. It's licensed under BSD3. Thanks to everyone who has submitted patches.
