Kibitzer's Corner
May-13-05  Caissanist: Belle was a very strong computer chess machine (not just a program) that won many computer chess tournaments in the eighties. It was built by Ken Thompson of Bell Labs, best known as the co-creator of the Unix operating system. Supposedly many of the programming techniques that Thompson used were widely emulated in later programs

Jul-13-09  ILikeFruits: a tale as old as time...
true as it can be...
barely even friends...
then somebody bends unexpectedly...
just a little change...
small to say the least...
both a little scared...
not one prepared...

  BishopBerkeley: NY Times: Computer (Chess) Pioneer Wins Prestigious Japan Prize


Ken Thompson and Dennis Ritchie, the inventors of the Unix operating system and C programming language, have been awarded the Japan Prize, according to the San Francisco Chronicle [ ]. The prize goes each year to people whose work “aims to promote the advancement of science and technology for the peace and prosperity of mankind.” The award is for $600,000. Ten previous recipients have also won Nobel Prizes.

Both Thompson and Ritchie were working at Bell Laboratories in the 1960’s when they invented Unix and C. They went on to have distinguished careers and are legends in the computer world.

Thompson, 67, is a “distinguished engineer” for Google, and Ritchie, 69, retired in 2007 from Lucent Technologies (now Alcatel Lucent), a successor to AT&T Technologies.

In the late 1970’s, while he was at Bell, Thompson became interested in chess computers and along with Joe Condon developed Belle [ ], the first chess computer to achieve a master rating (above 2,200).

(Full disclosure, I played Belle twice, somewhere around 1982. I drew one game and lost one. If I had known then what I know now about the man sitting across from me running the computer — Thompson — I might have thought to kowtow to him.)

Chessbase has a wonderful retrospective [ ] of Thompson and Belle, along with a number of photographs of Thompson at the London Chess Classic last month [ ].
