Deep Blue

A super computer developed by researchers at IBM to explore the use of parallel processing to solve complex computing problems. It is known as the first computer to beat the current chess World Grand Master.

Deep Blue started it's life as a PhD project at Carnegie Mellon University by PhD students Feng-hsiung Hsu and Murray Campbell. Chiptest, as it was known then, consisted of a custom designed chip hosted in a Sun 3/160 computer.

The project moved over to IBM in 1989 when Hsu and Campbell joined IBM. Deep Thought, as it was known by then, played for the first time against Garry Kasparov in the same year. The game of two matches was easily won by Kasparov.

The next match against Kasparov took place in February 1996. By then the machine was again renamed, at that time it was known as Deep Blue. It was also heavily re-engineered: it was by then running on a 32-node RS/6000 cluster, each containing 8 custom designed chips. Alas, Kasparov won again.

The breakthrough finally happened in February 1997: with both the algorithm and the raw speed significantly improved, Deep Blue beat Kasparov 3.5:2.5.

deep magic

[possibly from C. S. Lewis's "Narnia" books] An awesomely arcane technique central to a program or system, especially one neither generally published nor available to hackers at large (compare black art); one that could only have been composed by a true wizard. Compiler optimisation techniques and many aspects of OS design used to be deep magic; many techniques in cryptography, signal processing, graphics, and AI still are. Compare heavy wizardry. Especially found in comments of the form "Deep magic begins here.". Compare voodoo programming.

deep space

1. The notional location of any program that has gone off the trolley. Especially used of programs that just sit there silently grinding long after either failure or some output is expected. "Uh oh. I should have had a prompt ten seconds ago. The program's in deep space somewhere." Compare buzz, catatonic, hyperspace.

2. The metaphorical location of a human so dazed and/or confused or caught up in some esoteric form of bogosity that he or she no longer responds coherently to normal communication.
