I took this class as well and agree that it was the most useful course I took at Penn. I still use all of the things that I learned in this class every day (especially emacs). Luckily, I took it early in school and it made subsequent classes so much easier. Thank you Perry Metzger!

He recently had a really interesting talk called Emacs: The Editor for the Next Forty Years [1]
