I'm an entrepreneur and computer scientist, with a particular interest in Artificial Intelligence and Peer-to-Peer. My two most notable projects are Freenet and Revver (I'm founder and co-founder respectively). My current projects are a predictive analytics system called SenseArray, and a new approach to distributed computation called Swarm. You can find my personal blog here.
While I've used C, C++, ML, Haskell, Prolog, Python, even Perl in the past, these days I do most of my programming in Java. I am gaining experience with Scala though and expect to become my primary language as it and its tools mature. I was honored to be asked by Scala's creator to be on the program committee for the first Scala workshop.
