I used Harvard's computer system only once as an undergraduate, to run regressions for my senior thesis on the economics of spousal abuse. The data was stored on large, heavy magnetic tapes that I had to lug in big boxes across campus, cursing the entire way and arriving in a sweaty mess at the sole computer center, which was populated exclusively with male students. I then had to stay up all night spinning the tapes to input the data. When I tried to execute my final calculations, I took down the entire system. That's right. Years before Mark famously crashed that same Harvard system, I beat him to it.
