Wow, thank you for that link. Never saw it before. Perlis really did deliver on his intention to give us a "pou sto to last the student for 40 years, not a handbook for tomorrow’s employment." Every time I've encountered a new language or framework (Java, Ruby, Rails, whatever), I've been grateful to him. He also delivered on his intention to keep us "on the computer early and often." I didn't get much sleep that semester -- now I see that was by design :)
