СКАЧАТЬ two cartoon eyes and a mouth. A few others have been reported.

      :black art: n. A collection of arcane, unpublished, and (by implication) mostly ad-hoc techniques developed for a particular application or systems area (compare {black magic}). VLSI design and compiler code optimization were (in their beginnings) considered classic examples of black art; as theory developed they became {deep magic}, and once standard textbooks had been written, became merely {heavy wizardry}. The huge proliferation of formal and informal channels for spreading around new computer-related technologies during the last twenty years has made both the term `black art' and what it describes less common than formerly. See also {voodoo programming}.

      :black hole: n. When a piece of email or netnews disappears mysteriously between its origin and destination sites (that is, without returning a {bounce message}) it is commonly said to have `fallen into a black hole'. "I think there's a black hole at foovax!" conveys suspicion that site foovax has been dropping a lot of stuff on the floor lately (see {drop on the floor}). The implied metaphor of email as interstellar travel is interesting in itself. Compare {bit bucket}.

      :black magic: n. A technique that works, though nobody really understands why. More obscure than {voodoo programming}, which may be done by cookbook. Compare also {black art}, {deep magic}, and {magic number} (sense 2).

      :blargh: /blarg/ [MIT] n. The opposite of {ping}, sense 5; an exclamation indicating that one has absorbed or is emitting a quantum of unhappiness. Less common than {ping}.

      :blast: 1. vt.,n. Synonym for {BLT}, used esp. for large data sends over a network or comm line. Opposite of {snarf}. Usage: uncommon. The variant `blat' has been reported. 2. vt. [HP/Apollo] Synonymous with {nuke} (sense 3). Sometimes the message `Unable to kill all processes. Blast them (y/n)?' would appear in the command window upon logout.

      :blat: n. 1. Syn. {blast}, sense 1. 2. See {thud}.

      :bletch: /blech/ [from Yiddish/German `brechen', to vomit, poss. via comic-strip exclamation `blech'] interj. Term of disgust. Often used in "Ugh, bletch". Compare {barf}.

      :bletcherous: /blech'*-r*s/ adj. Disgusting in design or function; esthetically unappealing. This word is seldom used of people. "This keyboard is bletcherous!" (Perhaps the keys don't work very well, or are misplaced.) See {losing}, {cretinous}, {bagbiter}, {bogus}, and {random}. The term {bletcherous} applies to the esthetics of the thing so described; similarly for {cretinous}. By contrast, something that is `losing' or `bagbiting' may be failing to meet objective criteria. See also {bogus} and {random}, which have richer and wider shades of meaning than any of the above.

      :blinkenlights: /blink'*n-li:tz/ n. Front-panel diagnostic lights on a computer, esp. a {dinosaur}. Derives from the last word of the famous blackletter-Gothic sign in mangled pseudo-German that once graced about half the computer rooms in the English-speaking world. One version ran in its entirety as follows:

      ACHTUNG! ALLES LOOKENSPEEPERS! Das

       computermachine ist nicht fuer gefingerpoken und mittengrabben.

       Ist easy schnappen der springenwerk, blowenfusen und poppencorken

       mit spitzensparken. Ist nicht fuer gewerken bei das dumpkopfen.

       Das rubbernecken sichtseeren keepen das cotten-pickenen hans in das

       pockets muss; relaxen und watchen das blinkenlichten.

      This silliness dates back at least as far as 1959 at Stanford

       University and had already gone international by the early 1960s,

       when it was reported at London University's ATLAS computing site.

       There are several variants of it in circulation, some of which

       actually do end with the word `blinkenlights'.

      In an amusing example of turnabout-is-fair-play, German hackers

       have developed their own versions of the blinkenlights poster in

       fractured English, one of which is reproduced here:

      ATTENTION This room is fullfilled mit special electronische equippment. Fingergrabbing and pressing the cnoeppkes from the computers is allowed for die experts only! So all the "lefthanders" stay away and do not disturben the brainstorming von here working intelligencies. Otherwise you will be out thrown and kicked anderswhere! Also: please keep still and only watchen astaunished the blinkenlights.

      See also {geef}.

      :blit: /blit/ vt. 1. To copy a large array of bits from one part of a computer's memory to another part, particularly when the memory is being used to determine what is shown on a display screen. "The storage allocator picks through the table and copies the good parts up into high memory, and then blits it all back down again." See {bitblt}, {BLT}, {dd}, {cat}, {blast}, {snarf}. More generally, to perform some operation (such as toggling) on a large array of bits while moving them. 2. All-capitalized as `BLIT': an early experimental bit-mapped terminal designed by Rob Pike at Bell Labs, later commercialized as the AT&T 5620. (The folk etymology from `Bell Labs Intelligent Terminal' is incorrect.)

      :blitter: /blit'r/ n. A special-purpose chip or hardware system built to perform {blit} operations, esp. used for fast implementation of bit-mapped graphics. The Commodore Amiga and a few other micros have these, but in 1991 the trend is away from them (however, see {cycle of reincarnation}). Syn. {raster blaster}.

      :blivet: /bliv'*t/ [allegedly from a World War II military term meaning "ten pounds of manure in a five-pound bag"] n. 1. An intractable problem. 2. A crucial piece of hardware that can't be fixed or replaced if it breaks. 3. A tool that has been hacked over by so many incompetent programmers that it has become an unmaintainable tissue of hacks. 4. An out-of-control but unkillable development effort. 5. An embarrassing bug that pops up during a customer demo.

      This term has other meanings in other technical cultures; among experimental physicists and hardware engineers of various kinds it seems to mean any random object of unknown purpose (similar to hackish use of {frob}). It has also been used to describe an amusing trick-the-eye drawing resembling a three-pronged fork that appears to depict a three-dimensional object until one realizes that the parts fit together in an impossible way.

      :BLOB: [acronym, Binary Large OBject] n. Used by database people to

       refer to any random large block of bits which needs to be stored in

       a database, such as a picture or sound file. The essential point

       about a BLOB is that it's an object you can't interpret within the

       database itself.

      :block: [from process scheduling terminology in OS theory] 1. vi.

       To delay or sit idle while waiting for something. "We're blocking

       until everyone gets here." Compare {busy-wait}. 2. `block

       on' vt. To block, waiting for (something). "Lunch is blocked on

       Phil's arrival."

      :block transfer computations: n. From the television series

       "Dr. Who", in which it referred to computations so fiendishly

       subtle and complex that they could not be performed by machines.

       Used to refer to any task that should be expressible СКАЧАТЬ
