This is probably a rhetorical posting since this area seems to be most frequented by people whom are already Linux enthusiasts, but I wanted to share anyway just in case any other newbies stumbled in to this section of BC.
While camping over the weekend, I broke one of my usually self-imposed rules... I brought my netbook with me. And I took some time to watch two documentary's about Linux and some of its history. While The Code (2001) and Revolution OS (2001) are somewhat older films, they were totally awesome! Conception, origin, history, challenges, the inevitable spread around the world -- it's all there and more.
There are obviously plenty of great talks, presentations, etc., on YouTube, TED, and elsewhere for those that prefer more concise topics. But if you can spare a few minutes for each documentary I'm sure you won't be disappointed if you have any interest in Linux.
(Hey, if any of you Linux guru's know of any similar films, please share the titles!)
