Re: [TUHS] IP in v8-v10

Can't help much, but I did write fish and ching. ching took a string from the input, hashed it, converted into hexagrams, and quoted a couple of lines of i Ching text .  The text was copied from a book, presumably copyrighted, although considering how long ago this all was maybe the copyright has expired now... I wrote fish for my young son -- it played the kids game.  Without graphics it wasn't very compelling.  But there is an interesting story about it.  A couple of weeks after the first version, I realized that if my opponent (e.g., the computer) asked me for, e.g. a six, and later I drew a six, I should ask the opponent for sixes.  With this small change the game defeated all kids and most adults, and the game was even less interesting as a result.  I ended up putting in an option to dumb the game back to its original level. A couple of years later, at a Usenix meeting, I was publicly called out for writing a game "that cheated".    Unless somebody hacked my code somewhere along the way, the game simply played excellent strategy...

Here's a list, gathered from the manuals, of stuff that Bell Labs may not have the right to redistribute, with some (uncertain) attributions of origin. I did not check to see which of them appear in the TUHS archives; I doubt that /usr/src fully covered /bin and /usr/bin. This list is at best a first draft. Please weigh in with corrections.
