DEC
  • n. Digital Equipment Corporation. Before the killer micro revolution of the late 1980s, hackerdom was closely symbiotic with DEC's pioneering timesharing machines. The first of the group of cultures described by this lexicon nucleated around the PDP-1 (see TMRC. Subsequently, the PDP-6, PDP-10, PDP-20, PDP-11 and VAX were all foci of large and important hackerdoms, and DEC machines long dominated the ARPANET and Internet machine population. DEC was the technological leader of the minicomputer era (roughly 1967 to 1987), but its failure to embrace microcomputers and UNIX early cost it heavily in profits and prestige after silicon got cheap. However, the microprocessor design tradition owes a heavy debt to the PDP-11 instruction set, and every one of the major general-purpose microcomputer OSs so far (CP/M, MS-DOS, UNIX, OS/2) were either genetically descended from a DEC OS, or incubated on DEC hardware, or both. Accordingly, DEC is still regarded with a certain wry affection even among many hackers too young to have grown up on DEC machines. The contrast with IBM is instructive.
  • v. Verbal (and only rarely written) shorthand for decrement, i. e. `decrease by one'. Especially used by assembly programmers, as many assembly languages have a `dec' mnemonic. Antonym inc.
