If you were unable to attend the first annual LinuxCon, but were excited about the subject matter, you're in luck. The Linux Foundation has released video and slides from some the LinuxCon presentations on their website.
To give you a sample of the content that is archived, here is a video of Mark Shuttleworth, CEO of Canonical and founder of the Ubuntu OS talking about coordinated software releases and the Linux ecosystem.
For the more technically oriented, The Linux Plumbers Conference video has also been uploaded, as well. Below is a video of Linus Torvalds giving an in depth tutorial on Git.
Additional video archives (synched with slides) are also available from Linux Pro Magazine. Some of these additional archives have additional fees.
