And paper debugging!

Fond memories of printing programs on continuous printer paper (paper with holes on the side, that many dot-matrix printers used) so that I could take my time to read them to figure out where the bugs where.

I've always dreamed of doing that.

Whenever I proofread papers in college, I would always print them out. There's something about being able to physically hold the paper that makes keeping the whole idea in your head easier that just isn't possible on a screen, for me at least.
