It looks like everything after dynamic programming in 2007 is missing the video, including the lecture where he builds a proof of NP-hardness from a randomly selected problem in class.
/That/ is something I'd like to watch!
I was there - but I don't remember the problem we chose.
Sorry.
But is was cool.
It's amazing how much that picture on the right looks like Weird Al in the "White and Nerdy" music video.
Is the audio on the 2007 videos very quiet for everyone else as well?
