It's a good thing my mom called and asked how classes were going, or I might not have thought about that, and not checked my Accounting syllabus to find out that I have an exam tomorrow. Depending on how tired I am tomorrow (because of working on the bloody 420 project!) I might have decided to skip class.
Every once in a while I need a sheet of graph paper, and I use this program
in WINE to do it. I haven't seen an equivalent thing in linux, though I think it would be pretty easy to write. You could even write it in postscript :P
