I am talking about Randy Pausch, a computer science professor who was diagnosed with pancreatic cancer in September 2006.
As I mentioned in a comment on Stephen's post, the excerpted YouTube video doesn't even come close to the impact of the entire lecture (and which can be found in full here: http://www.cmu.edu/homepage/multimedia/randy-pausch-lecture.shtml ).
Randy and I are both IT geeks. We both love aspects of academia. we both have a loving wife and children who mean the world to us. And, of course, we have both been touched by cancer.
But there most of the similarities end. I have no evidence of disease, but Randy is struggling through palliative chemotherapy, the best outcome being a few more months of purchased time, something Randy called "a small price to pay for walking around."
