I'm durin42 on IRC. I work on a variety of things in Mercurial, but my primary interest is in large-scale repositories and better feature branch workflows. I also occasionally chip at removing our dependency on httplib (it's broken) and getting us to work under Python 3. hgsubversion is my fault, I review patches for hg-git, histedit is my fault. I think that about covers it. My [[https://bitbucket.org/durin42/|public repositories]] are on [[https://bitbucket.org/|BitBucket]] and [[http://hg.durin42.com|my own server]].
