At this year's CeBit 2009 trade fair, there was a dedicated exhibition area called the Open Source Forum. In addition to providing booths for various Open Source projects, they also had a stage for presentations about different topics. Every talk was recorded and available as a live stream during the show.
My dear colleague Simon Phipps spoke about "Adoption-Led: The Third Wave of Open Source" on Wednesday, I gave a presentation about "MySQL Backup and Security Best Practices" on Friday. The recording of these and all other talks as well as the Linux New Media Award ceremony are now available from the archives. Enjoy!
