Yesterday I found this talk [1] on the origin of silicon valley in the defense industry, linked in a comment here [2], and couldn't help but sit through the entire thing in one go. So I wonder, what other great, freely available talks or lectures does HN know about?Rules: Can be on any topic. Can be of any length. Ideally, should be a standalone talk.
