This is incredible, I was just on the Coursera website trying to go to my old courses to continue from where I've left off, but I couldn't get to them. The link to my previously enrolled courses was taking me to the newer version of those courses which haven't started yet. So I thought I'll search HN because I remember reading that someone was archiving these ... and boom! it's the top link on the front page! Yay HackerNews!!! There is some Voodoo-AI going on at HN!
