Here are a few video lectures I've enjoyed that simply never could have made it to Television. Too much of a niche audience I suppose. They'll go from most comprehensible to non-nerds/programmers to incomprehensible to non-nerds/programmers. Soon I'll post up something actually productive or cool. For now, it's all school.
I still really like Giles Bowkett's RubyFringe presentation from last year. It really starts in after the musical presentation of the first seven minutes. It's good fun even if you don't program and you can see a glimmer of why programmer's would be interested in what it is they do.
I also fervently love "The Graphing Calculator Story" which I read in text somewhere before stumbling across this video.
Finally, I watched Zed Shaw's CUSEC talk last night and was forced to conclude that I both like Zed Shaw and very much like his talk.
Now, when you need a break, watch something.
