alt Hacker NewsRTM was my TA at MIT for a CS/systems engineering course. It took the students until we did an assignment about the worm to realize who he was IIRC. The students thought it was very cool, but even then, as a TA covering the assignment, he didn't really talk about it.
He was also a TA at Harvard with Trevor Blackwell for CS 148 (computer networking, taught by H T Kung) at the time. I remember taking that with them in 1995.
