LinuxCon 2010 Boston
OK, this is another great video I found. This one is how the airline Virgin America has deployed Open Source software throughout their operation instead of all the vendor solutions their competitors keep using. I believe it's only 24 minutes long so pretty quick to view.
One of the things that struck me about this presentation, was the excitement of the presenter. He seemed truly excited to be at LinuxCon telling / showing developers how his company was using their hard work.
