"The number of UNIX installations has grown to 10, with more expected."
-- The UNIX programmer's manual, 2nd edition, june, 1972

So it's the start of the school term, and i find my most exciting class to be this computing class which is apparently going to be based on Unix. One outdated $50 textbook later, it's still quite interesting. This despite being in classes which on paper are supposed to be good and intellectually stimulating: econs of info and econs of crime. Time to switch major?
