Back in 1978, Bill Joy used to walk around with a fan-fold
printout of vi and/or csh. He'd pull up a chair and sit at a
term a few feet away. (This was when I was first learning
FORTRAN-IV and [ick] Pascal. ) He probably fixed dozrns of bugs
that way, walking thru the code. --Yes, I'm sure he was trying
to impress the girls too. (About a third of the intro
programming classes were female, then. And not many uglies,
either! (I'm not sexist or anything, just telling it like
it was:) Today I'm hearing there are fewer women students into
programming... dunno why.) Ken Arnold hacked the first curses
and termcap. Anyway, this is the BErkeley side of Unix.
ed was my first editor on the ADM. It was the next thing to
magic. vi blew it out of the water.
