L3 support engineer for Metaswitch Networks (stuff posted here isn't on behalf of my company &c. &c.). I hack around in Python, spend more time than I'd like with shell, and am proficient if somewhat rusty with C. I'm also the Git maintainer for Cygwin and a contributor to Dreamwidth.
You can also find me in a wide variety of larp fields, or on Twitter, Facebook, Google+, Wikipedia (which has by far the most complete profile), and other places by request.
