George Dyson's brief discussion about the origins of modern computation - including some humorous snippets from the first computer engineers' and programmers' notebooks - is available for you to see as a recorded TED video. This is a great way to relax and learn some interesting stuff at the end of the holiday weekend.
The George Dyson video is here. Ever since I had the privilege of seeing him talk in Mountain View recently I've been hoping to find any videos online...
(The little "expand" icon in the upper right of the video screen will make the slides much easier to see.)
