BBS has 4 nodes even though it has a single machine and no Internet link, confusing an Internet hacker no end.
NOMEX underwear /noh'meks uhn'-der-weir/ n. [Usenet] Syn. asbestos longjohns, used mostly in auto-related mailing lists and newsgroups. NOMEX underwear is an actual product available on the racing equipment market, used as a fire resistance measure and required in some racing series.
Nominal Semidestructor n. Soundalike slang for 'National Semiconductor', found among other places in the Networking/2 networking sources. During the late 1970s to mid-1980s this company marketed a series of microprocessors including the NS16000 and NS32000 and several variants. At one point early in the great microprocessor race, the specs on these chips made them look like serious competition for the rising Intel 80×86 and Motorola 680×0 series. Unfortunately, the actual parts were notoriously flaky and never implemented the full instruction set promised in their literature, apparently because the company couldn't get any of the mask steppings to work as designed. They eventually sank without trace, joining the Zilog Z8000 and a few even more obscure also-rans in the graveyard of forgotten microprocessors. Compare HP-SUX, AIDX, buglix, Macintrash, Telerat, Open DeathTrap, ScumOS, sun-stools.
non-optimal solution n. (also sub-optimal solution) An astoundingly stupid way to do something. This term is generally used in deadpan sarcasm, as its impact is greatest when the person speaking looks completely serious. Compare stunning. See also Bad Thing.
nonlinear adj. [scientific computation] 1. Behaving in an erratic and unpredictable fashion; unstable. When used to describe the behavior of a machine or program, it suggests that said machine or program is being forced to run far outside of design specifications. This behavior may be induced by unreasonable inputs, or may be triggered when a more mundane bug sends the computation far off from its expected course. 2. When describing the behavior of a person, suggests a tantrum or a flame. "When you talk to Bob, don't mention the drug problem or he'll go nonlinear for hours." In this context, go nonlinear connotes 'blow up out of proportion' (proportion connotes linearity).
nontrivial adj. Requiring real thought or significant computing power. Often used as an understated way of saying that a problem is quite difficult or impractical, or even entirely unsolvable ("Proving P=NP is nontrivial").
