WhatIs

/ri-strik-shən/

n. A bug or design error that limits a program's capabilities, and which is sufficiently egregious that nobody can quite work up enough nerve to describe it as a feature. Often used (esp. by marketroid types) to make it sound as though some crippling bogosity had been intended by the designers all along, or was forced upon them by arcane technical constraints of a nature no mere user could possibly comprehend (these claims are almost invariably false).

/rē-set/

[the MUD community]

v. In AberMUD, to bring all dead mobiles to life and move items back to their initial starting places. New players who can't find anything shout "Reset! Reset!" quite a bit. Higher-level players shout back "No way!" since they know where points are to be found. Used in RL, it means to put things back to the way they were when you found them.

/ri-plī/

n. See followup.

/re-plə-kāt-ər/

n. Any construct that acts to produce copies of itself; this could be a living organism, an idea (see meme), a program (see worm, wabbit, and virus), a pattern in a cellular automaton (see life, sense 1), or (speculatively) a robot or nanobot.

/ri-li-jəs i-shüz/

n. Questions which seemingly cannot be raised without touching off holy wars, such as "What is the best operating system (or editor, language, architecture, shell, mail reader, news reader)?", "What about that Heinlein guy, eh?", "What should we add to the new Jargon File?"

See holy wars; see also theology, bigot.

/rē-ən-vent t͟hə (h)wēl/

v. To design or implement a tool equivalent to an existing one or part of one, with the implication that doing so is silly or a waste of time. This is often a valid criticism. On the other hand, automobiles don't use wooden rollers, and some kinds of wheel have to be reinvented many times before you get them right. On the third hand, people reinventing the wheel do tend to come up with the moral equivalent of a trapezoid with an offset axle.

/rē-in-kär-ˈnā-shən, sī-kəl əv/

n. See cycle of reincarnation.

/reg'eksp/

[UNIX]

n. (alt. regex or reg-ex) 

/red bu̇k/

n. 1. Informal name for one of the three standard references on PostScript ('PostScript Language Reference Manual', Adobe Systems (Addison-Wesley, 1985; QA76.73.P67P67; ISBN 0-201-10174-2); the others are known as the Green Book and the Blue Book.

2. Informal name for one of the 3 standard references on Smalltalk ('Smalltalk-80: The Interactive Programming Environment' by Adele Goldberg (Addison-Wesley, 1984; QA76.8.S635G638; ISBN 0-201-11372-4); this too is associated with blue and green books).

/ri-kər-zhən a-krə-nim/

pl. n. A hackish (and especially MIT) tradition is to choose acronyms that refer humorously to themselves or to other acronyms. The classic examples were two MIT editors called EINE ("EINE Is Not EMACS") and ZWEI ("ZWEI Was EINE Initially"). More recently, there is a Scheme compiler called LIAR (Liar Imitates Apply Recursively), and GNU (q.v., sense 1) stands for "GNU's Not UNIX!" -- and a company with the name CYGNUS, which expands to "Cygnus, Your GNU Support".
