I have been developing software since 1990 and am currently working for Six Apart.
In addition to my day jobs I've been doing open source projects (SOAP::Lite, a popular webservices toolkit for Perl, and Blooki, a not so popular wiki/weblog tool), co-authoring books (Programming Web Services with SOAP and Programming Web Services with Perl), speaking at conferences (O'Reilly Open Source Convention and O'Reilly Peer-to-Peer & Web Services Conference), and occasionally posting to my blog.
I'm also interested in robotics, control theory, machine learning, cognitive modeling and general intelligence; here is my reading list of blogs and books/articles on these topics. In my spare time I am programming Lego NXT with NXC and Microsoft Robotics Development Studio.
