Artur Bergman, hacker and technologist at-large, is an enthusiastic apologist for federated identity and a board member of the OpenID Foundation.
He is currently on leave of absence from Six Apart, where he worked as an engineering manager of LiveJournal, operations architect for the combined operations group, and also co-authored djabberd, a high-performance, large-scale instant messaging server.
In past lives, he's built high volume financial trading systems running over the Internet and re-implemented Perl 5's threading system.
His current interests extend to encompass semantic search, large scale infrastructure, open source development, federated instant messaging, neurotransmitters, and the future of cyborgs.
