Many of you have no doubt already seen Carnegie Mellon computer scientist Randy Pausch's wildly popular 'last lecture', "Really Achieving Your Childhood Dreams". For those of you who haven't, watch it, seriously (it's embedded below, or click here. You can also download the lecture via iTunes). The back story, briefly, is that Pausch was diagnosed with pancreatic cancer in September 2006 and later given only a couple of months to live. He gave this lecture in September of 2007 and he died in July, 2008.
