=====

:N: /N/ quant. 1. A large and indeterminate number of objects: "There were N bugs in that crock!" Also used in its original sense of a variable name: "This crock has N bugs, as N goes to infinity." (The true number of bugs is always at least N + 1.) 2. A variable whose value is inherited from the current context. For example, when a meal is being ordered at a restaurant, N may be understood to mean however many people there are at the table. From the remark "We'd like to order N wonton soups and a family dinner for N - 1" you can deduce that one person at the table wants to eat only soup, even though you don't know how many people there are (see {great-wall}). 3. `Nth': adj. The ordinal counterpart of N, senses 1 and 2. "Now for the Nth and last time..." In the specific context "Nth-year grad student", N is generally assumed to be at least 4, and is usually 5 or more (see {tenured graduate student}). See also {{random numbers}}, {two-to-the-N}.

:nadger: /nad'jr/ [Great Britain] v. Of software or hardware (not people), to twiddle some object in a hidden manner, generally so that it conforms better to some format. For instance, string printing routines on 8-bit processors often take the string text from the instruction stream, thus a print call looks like jsr print:"Hello world"'. The print routine has tonadger' the return instruction pointer so that the processor doesn't try to execute the text as instructions.

:nailed to the wall: [like a trophy] adj. Said of a bug finally eliminated after protracted, and even heroic, effort.

:nailing jelly: vi. See {like nailing jelly to a tree}.

:na"ive: 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 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 beexperienced user' but is really more like `cynical user'.

:na"ive 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/ [from the ASCII mnemonic for 0010101] interj.

On-line joke answer to {ACK}?: "I'm not here."

On-line answer to a request for chat: "I'm not available."

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/ [CMU: from nanosecond'] n. 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 ofjiffy' is quite different ---

see {jiffy}).

:nano-: [SI: the next quantifier below {micro-}; meaning *

10^(-9)] pref. 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 ananocode' 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 whose switching elements are molecular in size. 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.

:nanofortnight: [Adelaide University] n. 1 fortnight * 10^-9, or about 1.2 msec. This unit was used largely by students doing undergraduate practicals. See {microfortnight}, {attoparsec}, and {micro-}.

:nanotechnology:: /nan'-oh-tek-no`l*-jee/ n. A hypothetical fabrication technology in which objects are designed and built with the individual specification and placement of each separate atom.

The first unequivocal nanofabrication experiments are taking place now (1990), for example with the deposition of individual xenon atoms on a nickel substrate to spell the logo of a certain very large computer company. Nanotechnology has been a hot topic in the hacker subculture ever since the term was coined by K. Eric Drexler in his book `Engines of Creation', where he predicted that nanotechnology could give rise to replicating assemblers, permitting an exponential growth of productivity and personal wealth. See also {blue goo}, {gray goo}, {nanobot}.

:nasal demons: n. During a discussion on the USENET group comp.std.c in early 1992, a regular remarked "When the compiler encounters [a given undefined construct] it is legal for it to make demons fly out of your nose" (the implication is that it may choose any arbitrarily bizarre way to interpret the code without violating the ANSI C standard). Someone else followed up with a reference to "nasal demons", which became recognized shorthand on that group for any unexpected behaviour of a C compiler on encountering an undefined construct.

:nastygram: /nas'tee-gram/ n. 1. A protocol packet or item of email (the latter is also called a {letterbomb}) that takes advantage of misfeatures or security holes on the target system to do untoward things. 2. Disapproving mail, esp. from a {net.god}, pursuant to a violation of {netiquette} or a complaint about failure to correct some mail- or news-transmission problem. Compare {shitogram}. 3. A status report from an unhappy, and probably picky, customer. "What'd Corporate say in today's nastygram?" 4. [deprecated] An error reply by mail from a {daemon}; in particular, a {bounce message}.

:Nathan Hale: n. An asterisk (see also {splat}, {{ASCII}}). Oh, you want an etymology? Notionally, from "I regret that I have only one asterisk for my country!", a misquote of the famous remark uttered by Nathan Hale just before he was hanged. Hale was a (failed) spy for the rebels in the American War of Independence.

:nature: n. See {has the X nature}.

:neat hack: n. 1. A clever technique. 2. A brilliant practical joke, where neatness is correlated with cleverness, harmlessness, and surprise value. Example: the Caltech Rose Bowl card display switch (see "{The Meaning of `Hack'}", appendix A). See also {hack}.

:neats vs. scruffies: n. The label used to refer to one of the continuing {holy wars} in AI research. This conflict tangles together two separate issues. One is the relationship between human reasoning and AI; neats' tend to try to build systems thatreason' in some way identifiably similar to the way humans report themselves as doing, while scruffies' profess not to care whether an algorithm resembles human reasoning in the least as long as it works. More importantly,neats' tend to believe that logic is king, while scruffies' favor looser, more ad-hoc methods driven by empirical knowledge. To aneat', scruffy' methods appear promiscuous and successful only by accident; to ascruffy', neat' methods appear to be hung up on formalism and irrelevant to the hard-to-capturecommon sense' of living intelligences.

:neep-neep: /neep neep/ [onomatopoeic, from New York SF fandom] n.

One who is fascinated by computers. More general than {hacker}, as it need not imply more skill than is required to boot games on a PC. The derived noun `neep-neeping' applies specifically to the long conversations about computers that tend to develop in the corners at most SF-convention parties. Fandom has a related proverb to the effect that "Hacking is a conversational black hole!".

:neophilia: /neeoh-fil'-ee-*/ n. The trait of being excited and pleased by novelty. Common trait of most hackers, SF fans, and members of several other connected leading-edge subcultures, including the pro-technologyWhole Earth' wing of the ecology movement, space activists, many members of Mensa, and the Discordian/neo-pagan underground. All these groups overlap heavily and (where evidence is available) seem to share characteristic hacker tropisms for science fiction, {{music}}, and {{oriental food}}.

:net.-: /net dot/ pref. [USENET] Prefix used to describe people and events related to USENET. From the time before the {Great Renaming}, when most non-local newsgroups had names beginning net.'. Includes {net.god}s,net.goddesses' (various charismatic net.women with circles of on-line admirers), net.lurkers' (see {lurker}),net.person', `net.parties' (a synonym for {boink}, sense 2), and many similar constructs. See also {net.police}.

:net.god: /net god/ n. Used to refer to anyone who satisfies some combination of the following conditions: has been visible on USENET

for more than 5 years, ran one of the original backbone sites, moderated an important newsgroup, wrote news software, or knows Gene, Mark, Rick, Mel, Henry, Chuq, and Greg personally. See {demigod}. Net.goddesses such as Rissa or the Slime Sisters have (so far) been distinguished more by personality than by authority.

:net.personality:
