Brings me back to the fall of 1998, and many long Thursday nights spent working on problem sets. This was before you could do the exercises on the web, so you had to go into an ancient lab with grayscale terminals (unless you wanted to download a special version of emacs onto your computer). If you needed assistance, you had to get on the TA's help queue, which was written on a chalkboard.
Typically I would finish my problem set and emerge just in time to see the sun rise.
Bah. I took it in 1983, on a TOPS-20 machine iirc with vt100's. We might as well have submitted our work in crayon.
Now get off my lawn.
(Sussman's book was still notes at that point. I wouldn't have guessed it would turn into the institution that it has turned into.)
Now get off my lawn!
(There was no technical reason that problem sets were done in the lab - I think it was just less depressing to be coding at 3 a.m. when you knew you weren't alone).
One benefit of this is that sometimes great discussions about completely random--although usually technical--subjects emerge as everybody is procrastinating. It really makes even the most annoying homework assignment bearable.
