vdiff /vee'dif/ v.,n. Visual diff. The operation of finding differences between two files by eyeball search. The term optical diff has also been reported, and is sometimes more specifically used for the act of superimposing two nearly identical printouts on one another and holding them up to a light to spot differences. Though this method is poor for detecting omissions in the 'rear' file, it can also be used with printouts of graphics, a claim few if any diff programs can make. See diff.
veeblefester /vee'bU0259.gifl-fes'tr/ n. [from the "Born Loser" comix via Commodore; probably originally from Mad Magazine's 'Veeblefeetzer' parodies ca. 1960] Any obnoxious person engaged in the (alleged) professions of marketing or management. Antonym of hacker. Compare suit, marketroid.
ventilator card n. Syn. lace card.
Venus flytrap n. [after the insect-eating plant] See firewall machine.
verbage /ver'bU0259.gifj/ n. A deliberate misspelling and mispronunciation of verbiage that assimilates it to the word 'garbage'. Compare content-free. More pejorative than 'verbiage'.
verbiage n. When the context involves a software or hardware system, this refers to documentation. This term borrows the connotations of mainstream 'verbiage' to suggest that the documentation is of marginal utility and that the motives behind its production have little to do with the ostensible subject.
Version 7 alt. V7 /vee' se'vn/ n. The first widely distributed version of Unix, released unsupported by Bell Labs in 1978. The term is used adjectivally to describe Unix features and programs that date from that release, and are thus guaranteed to be present and portable in all Unix versions (this was the standard gauge of portability before the POSIX and IEEE 1003 standards). Note that this usage does not derive from the release being the "seventh version of Unix"; research Unix at Bell Labs has traditionally been numbered according to the edition of the associated documentation. Indeed, only the widely-distributed Sixth and Seventh Editions are widely known as V[67]; the OS that might today be known as 'V10' is instead known in full as "Tenth Edition Research Unix" or just "Tenth Edition" for short. For this reason, "V7" is often read by cognoscenti as ''Seventh Edition". See BSD, USG Unix, Unix. Some old-timers impatient with commercialization and kernel bloat still maintain that V7 was the Last True Unix.
