I worked on the ARPANET project under Steve Crocker at UCLA and met his bud Vint there (with his ever-present 3 piece suit, briefcase, and hearing aids) ... what a great guy. An anecdote: I wrote a program (in Sigma-7 assembler I think) to play Jotto--a bit like Mastermind but with 5 letter words. Vint loved to poke around in people's directories to see what they were up to and found my program. He played it a few times, and then collared me to ask me a couple of questions: 1) It seemed to know some of the words he entered but not all -- what was up with that? 2) What sort of AI algorithm was I using for the program to make guesses? (It usually beat the human player.) Answers: 1) I didn't have a digitized dictionary (it was 1969!) so I hand-entered the five letter words from a pocket dictionary but got tired halfway through so it only knew words starting with a-l. 2) The program would eliminate any words that didn't fit the responses to its guesses so far and then pick a remaining word at random. Upon hearing my answers Vint walked away in disgust! But years later he gave me a recommendation when I interviewed with Google (it didn't work out for other reasons). I also shared a cubicle wall with another Van Nuys High alumni, Jon Postel, aka "God of the Internet". Sartorially, Jon was the complete opposite of Vint--long scraggly beard, blue jeans, forever barefoot--but those weren't the things that mattered. Man, those were the days.
