A few of Bryan Cantrill's talks have already been mentioned here, but this one about DTrace, from 2007, is a gem: https://www.youtube.com/watch?v=TgmA48fILq8 https://www.youtube.com/watch?v=TgmA48fILq8 I especially like the part in the middle where he tells the story of how a an awful GNOME applet was killing a Sun Ray server, and how he tracked down the culprit with DTrace.
