  • teco — (editor, text)   /tee'koh/ (Originally an acronym for "[paper] Tape Editor and COrrector"; later, "Text Editor and COrrector"]) 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. The first Emacs editor was written in TECO. It was noted for its powerful programming-language-like features and its unspeakably hairy syntax (see write-only language). TECO programs are said to resemble line noise. Every string of characters is a valid TECO program (though probably not a useful one); one common game used to be predict what the TECO commands corresponding to human names did. 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 "^P" means "sort" and "J<.-Z; ... L>" is an idiomatic series of commands for "do once for every line". By 1991, Emacs had replaced TECO in hacker's affections but descendants of an early (and somewhat lobotomised) version adopted by DEC can still be found lurking on VMS and a couple of crufty PDP-11 operating systems, and ports of the more advanced MIT versions remain the focus of some antiquarian interest.

  • tice — to tempt or to allure; to entice
  • tick — a score or account.
  • tico — a native or inhabitant of Costa Rica.
  • tmrc — /tmerk'/ The Tech Model Railroad Club at MIT, one of the wellsprings of hacker culture. The 1959 "Dictionary of the TMRC Language" compiled by Peter Samson included several terms that became basics of the hackish vocabulary (see especially foo, mung, and frob). By 1962, TMRC's legendary layout was already a marvel of complexity (and has grown in the thirty years since; all the features described here are still present). The control system alone featured about 1200 relays. There were scram switches located at numerous places around the room that could be thwacked if something undesirable was about to occur, such as a train going full-bore at an obstruction. Another feature of the system was a digital clock on the dispatch board, which was itself something of a wonder in those bygone days before cheap LEDS and seven-segment displays. When someone hit a scram switch the clock stopped and the display was replaced with the word "FOO"; at TMRC the scram switches are therefore called "foo switches". Steven Levy, in his book "Hackers", gives a stimulating account of those early years. TMRC's Power and Signals group included most of the early PDP-1 hackers and the people who later bacame the core of the MIT AI Lab staff. This dictionary accordingly includes a number of entries from the TMRC dictionary (via the Hacker Jargon File).
