On January 28, 1997, Ian Goldberg took on RSA Data Security's challenge and cracked the 40-bit code by linking together 250 idle workstations that allowed him to test 100 billion possible "keys" per hour. In three and a half hours Goldberg decoded the message, which read, "This is why you should use a longer key."

Teergrube, which is the German word for tar pit, is a trap for spammers who use an address harvester; a mail server deliberately set up to be really slow. To activate it, scatter addresses that look like users on the teergrube's host in places where the address harvester will be trolling. The address harvester will collect the address. When the spammer tries to mailbomb it, his mailer will get stuck.

In 1831, Dr. Joseph Antoine Plateau and Dr. Simon Rittrer constructed the Phenakitstoscope, which produced an illusion of movement by allowing a viewer to gaze at a rotating disk containing small windows, behind which was another disk containing a sequence of images. When the disks were rotated at the correct speed, the synchronization of the windows with the images created an animated effect.

Gedanken is the German word for 'thought' and it has a pejorative connotation among hackers. It refers to a project, especially one in artificial intelligence research that is written up in grand detail without ever being implemented to any great extent. Such a project is usually perpetrated by people who aren't very good hackers or find programming distasteful or are just in a hurry.

The term "Hysterical reasons", a variant on the phrase "for historical reasons", indicates specifically that something must be done in some stupid way for backward compatibility and that the feature it must be compatible with was the result of a bad design in the first place.
