Bruce Perens was one of the keynote speakers at the 2012 Linux.conf.au conference held in Ballarat, Australia January 16-20, 2012. I really enjoyed his presentation so I'm sharing it below. The linux.conf.au folks have posted videos for all of their presentations to their YouTube channel. I downloaded all of them and posted them to an archive.org LCA2012 page. They are also available in ogg format.
