:nailed to the wall: /adj./ [like a trophy] Said of a bug finally eliminated after protracted, and even heroic, effort.
:nailing jelly: /vi./ See {like nailing jelly to a tree}.
:naive: /adj./ Untutored in the perversities of some particular program or system; one who still tries to do things in an intuitive way, rather than the right way (in really good designs these coincide, but most designs aren't `really good' in the appropriate sense). This trait is completely unrelated to general maturity or competence, or even competence at any other specific program. It is a sad commentary on the primitive state of computing that the natural opposite of this term is often claimed to be `experienced user' but is really more like `cynical user'.
:naive user: /n./ A {luser}. Tends to imply someone who is ignorant mainly owing to inexperience. When this is applied to someone who *has* experience, there is a definite implication of stupidity.
:NAK: /nak/ /interj./ [from the ASCII mnemonic for 0010101] 1. On-line joke answer to {ACK}?: "I'm not here." 2. On-line answer to a request for chat: "I'm not available." 3. Used to politely interrupt someone to tell them you don't understand their point or that they have suddenly stopped making sense. See {ACK}, sense 3. "And then, after we recode the project in COBOL…." "Nak, Nak, Nak! I thought I heard you say COBOL!"
:nano: /nan'oh/ /n./ [CMU: from `nanosecond'] A brief period of time. "Be with you in a nano" means you really will be free shortly, i.e., implies what mainstream people mean by "in a jiffy" (whereas the hackish use of `jiffy' is quite different — see {jiffy}).
:nano-: /pref./ [SI: the next quantifier below {micro-}; meaning * 10^(-9)] Smaller than {micro-}, and used in the same rather loose and connotative way. Thus, one has {{nanotechnology}} (coined by hacker K. Eric Drexler) by analogy with `microtechnology'; and a few machine architectures have a `nanocode' level below `microcode'. Tom Duff at Bell Labs has also pointed out that "Pi seconds is a nanocentury". See also {{quantifiers}}, {pico-}, {nanoacre}, {nanobot}, {nanocomputer}, {nanofortnight}.
:nanoacre: /nan'oh-ay`kr/ /n./ A unit (about 2 mm square) of
real estate on a VLSI chip. The term gets its giggle value from
the fact that VLSI nanoacres have costs in the same range as real
acres once one figures in design and fabrication-setup costs.
:nanobot: /nan'oh-bot/ /n./ A robot of microscopic
proportions, presumably built by means of {{nanotechnology}}. As
yet, only used informally (and speculatively!). Also called a
`nanoagent'.
:nanocomputer: /nan'oh-k*m-pyoo'tr/ /n./ A computer with molecular-sized switching elements. Designs for mechanical nanocomputers which use single-molecule sliding rods for their logic have been proposed. The controller for a {nanobot} would be a nanocomputer.
