W2K bug //

[from 'Y2K bug' for the Year 2000 problem] The upcoming deployment of Microsoft's Windows 2000 operating system, which hackers generally expect will be among the worst train wrecks in the history of software engineering. Such is the power of Microsoft marketing, however, that it is also expected this will not become obvious until it has incurred hundreds of millions of dollars in downtime and lost opportunity costs.

wabbit /wab'it/ n.

[almost certainly from Elmer Fudd's immortal line "You wascawwy wabbit!"]

1. A legendary early hack reported on a System/360 at RPI and elsewhere around 1978; this may have descended (if only by inspiration) from a hack called RABBITS reported from 1969 on a Burroughs 5500 at the University of Washington Computer Center. The program would make two copies of itself every time it was run, eventually crashing the system.

2. By extension, any hack that includes infinite self-replication but is not a virus or worm. See fork bomb and rabbit job, see also cookie monster.

WAITS /wayts/ n.

The mutant cousin of TOPS-10 used on a handful of systems at SAIL up to 1990. There was never an 'official' expansion of WAITS (the name itself having been arrived at by a rather sideways process), but it was frequently glossed as 'West-coast Alternative to ITS'. Though WAITS was less visible than ITS, there was frequent exchange of people and ideas between the two communities, and innovations pioneered at WAITS exerted enormous indirect influence. The early screen modes of EMACS, for example, were directly inspired by WAITS's 'E' editor -- one of a family of editors that were the first to do 'real-time editing', in which the editing commands were invisible and where one typed text at the point of insertion/overwriting. The modern style of multi-region windowing is said to have originated there, and WAITS alumni at XEROX PARC and elsewhere played major roles in the developments that led to the XEROX Star, the Macintosh, and the Sun workstations. Also invented there were bucky bits -- thus, the ALT key on every IBM PC is a WAITS legacy. One WAITS feature very notable in pre-Web days was a news-wire interface that allowed WAITS hackers to read, store, and filter AP and UPI dispatches from their terminals; the system also featured a still-unusual level of support for what is now called 'multimedia' computing, allowing analog audio and video signals to be switched to programming terminals.

waldo /wol'doh/ n.

[from Robert A. Heinlein's story "Waldo"]

1. A mechanical agent, such as a gripper arm, controlled by a human limb. When these were developed for the nuclear industry in the mid-1940s they were named after the invention described by Heinlein in the story, which he wrote in 1942. Now known by the more generic term 'telefactoring', this technology is of intense interest to NASA for tasks like space station maintenance.
