From Jargon File (4.2.0, 31 JAN 2000) [jargon]: | |
Technobabble John Barry MIT Press 1991 ISBN 0-262-02333-4 Barry's book takes a critical and humorous look at the `technobabble' of acronyms, neologisms, hyperbole, and metaphor spawned by the computer industry. Though he discusses some of the same mechanisms of jargon formation that occur in hackish, most of what he chronicles is actually suit-speak -- the obfuscatory language of press releases, marketroids, and Silicon Valley CEOs rather than the playful jargon of hackers (most of whom wouldn't be caught dead uttering the kind of pompous, passive-voiced word salad he deplores). | |

TECO /tee'koh/ n.,v. obs. 1. [originally an acronym for `[paper] Tape Editor and COrrector'; later, `Text Editor and COrrector'] n. A text editor developed at MIT and modified by just about everybody. With all the dialects included, TECO may have been the most prolific editor in use before {EMACS}, to which it was directly ancestral. Noted for its powerful programming-language-like features and its unspeakably hairy syntax. It is literally the case that every string of characters is a valid TECO program (though probably not a useful one); one common game used to be mentally working out what the TECO commands corresponding to human names did. 2. vt. Originally, to edit using the TECO editor in one of its infinite variations (see below). 3. vt.,obs. To edit even when TECO is _not_ the editor being used! This usage is rare and now primarily historical. As an example of TECO's obscurity, here is a TECO program that takes a list of names such as: Loser, J. Random Quux, The Great Dick, Moby sorts them alphabetically according to surname, and then puts the surname last, removing the comma, to produce the following: Moby Dick J. Random Loser The Great Quux The program is [1 J^P$L$$ J <.-Z; .,(S,$ -D .)FX1 @F^B $K :L I $ G1 L>$$ (where ^B means `Control-B' (ASCII 0000010) and $ is actually an {alt} or escape (ASCII 0011011) character). In fact, this very program was used to produce the second, sorted list from the first list. The first hack at it had a {bug}: GLS (the author) had accidentally omitted the `@' in front of `F^B', which as anyone can see is clearly the {Wrong Thing}. It worked fine the second time. There is no space to describe all the features of TECO, but it may be of interest that `^P' means `sort' and `J<.-Z; ... L>' is an idiomatic series of commands for `do once for every line'. In mid-1991, TECO is pretty much one with the dust of history, having been replaced in the affections of hackerdom by {EMACS}. Descendants of an early (and somewhat lobotomized) version adopted by DEC can still be found lurking on VMS and a couple of crufty PDP-11 operating systems, however, and ports of the more advanced MIT versions remain the focus of some antiquarian interest.

technetium Symbol: Tc Atomic number: 43 Atomic weight: (98) Radioactive metallic transition element. Can be detected in some stars and the fission products of uranium. First made by Perrier and Segre by bombarding molybdenum with deutrons, giving them Tc-97. Tc-99 is the most stable isotope with a half-life of 2.6*10^6 years. Sixteen isotopes are known. Organic technetium compounds are used in bone imaging. Chemical properties are intermediate between rhenium and manganese. |
