Hal 

1. The HAL-9000 computer, guardian of the spacecraft Discovery in the novels and films of 2001: A Space Odyssey and its sequel, 2010. First activated at the HAL plant in Urbana, Illinois on January 12, 1997 (or 1992 in the film version). HAL is short for Heuristic ALgorithmic, and not derived by moving one letter back from the initials of IBM, as some have suggested. HAL's apparently psychotic behaviour in 2001 is revealed in the novel, and in either version of 2010, to have been a result of a neurosis arising from conflicts between his programming to accurately input, analyse and output information, and the demands of national security mandated by the Pentagon.

2. Any troublesome, wary or otherwise bloody-mindedly unhelpful computer.

Open the pod bay doors, Hal.

Hal 

The most wonderful boyfriend a girl could ever ask for. No one is better then him. He is the prime example of a girl's perfect boyfriend. He's sweet, compassionate, caring, creative, silly, fun, and gorgeous. His hobbies include mixing bad drinks, airsoft, video games, and hanging out with his girlfriend.

I'm so jealous, I wish I was dating a guy like Hal

hal 

Acronym for Hardware Abstraction Layer. The HAL is used by NT-based Operating Systems to handle hardware. This prevents the OS from having direct access to hardware.

The HAL is one of the main reaons that NT-based OS's are more stable than Win9.x.
