GIGO

GIGO (Garbage In, Garbage Out) refers to the fact that computers, unlike humans, will unquestioningly process the most nonsensical of input data and produce nonsensical output. GIGO is usually said in response to lusers* who complain that a program didn't "do the right thing" when given imperfect input or otherwise mistreated in some way.

Luser - A user who is also a loser.

The Devil Book

The "Devil Book" refers to "The Design and Implementation of the 4.3BSD Unix Operating System", by Samuel J. Leffler, Marshall Kirk McKusick, Michael J. Karels and John S. Quarterman. The book, which is a standard reference book on the internals of BSD Unix, is so called because the cover has a picture depicting a little devil (a visual play on daemon) in sneakers, holding a pitchfork (referring to one of the characteristic features of Unix, the "fork" system call).

Original PC Motherboard

The original PC motherboard, which premiered in 1982, was a large printed circuit card that contained the 8088 microprocessor, the BIOS, sockets for the CPU's RAM and a collection of slots that auxiliary cards could plug into. Additions like a floppy disk drive or a parallel port or a joystick needed a separate card that was plugged into one of the slots.

Lehigh

Featurectomy

Featurectomy is the act of removing a feature from a program. There are two types of featurectomies, the "righteous" and the "reluctant". Righteous featurectomies are performed when the remover believes the program would be more elegant without the feature, or there is a better way to achieve the same end. Reluctant featurectomies are done to satisfy some external constraint such as code size or execution speed.

Hao Jinglong & Hao Jingwen

In 1998, a Chinese court sentenced to death the twin brothers, Hao Jinglong and Hao Jingwen, for breaking into the Industrial and Commercial Bank of China computers and stealing $87,000. The Yangzhou Intermediate People's Court in the eastern Jiangsu province rejected Jingwen's appeal and upheld the death sentence, while suspending Jinglong's sentence in return for his testimony.

Atari Pong

When Atari Pong, the home version of the popular Atari arcade Pong game, was released in 1975, it made a huge cultural splash and started the video game boom. The game, sold through Sears-Roebuck, had two built-in controllers and of course, only played Pong.
