:IMHO: // /abbrev./ [from SF fandom via Usenet; abbreviation for `In My Humble Opinion'] "IMHO, mixed-case C names should be avoided, as mistyping something in the wrong case can cause hard-to-detect errors — and they look too Pascalish anyhow." Also seen in variant forms such as IMNSHO (In My Not-So-Humble Opinion) and IMAO (In My Arrogant Opinion).
:Imminent Death Of The Net Predicted!: /prov./ [Usenet] Since {Usenet} first got off the ground in 1980—81, it has grown exponentially, approximately doubling in size every year. On the other hand, most people feel the {signal-to-noise ratio} of Usenet has dropped steadily. These trends led, as far back as mid-1983, to predictions of the imminent collapse (or death) of the net. Ten years and numerous doublings later, enough of these gloomy prognostications have been confounded that the phrase "Imminent Death Of The Net Predicted!" has become a running joke, hauled out any time someone grumbles about the {S/N ratio} or the huge and steadily increasing volume, or the possible loss of a key node or link, or the potential for lawsuits when ignoramuses post copyrighted material, etc., etc., etc.
:in the extreme: /adj./ A preferred superlative suffix for many hackish terms. See, for example, `obscure in the extreme' under {obscure}, and compare {highly}.
:inc: /ink/ /v./ Verbal (and only rarely written) shorthand for increment, i.e. `increase by one'. Especially used by assembly programmers, as many assembly languages have an `inc' mnemonic. Antonym: {dec}.
:incantation: /n./ Any particularly arbitrary or obscure command that one must mutter at a system to attain a desired result. Not used of passwords or other explicit security features. Especially used of tricks that are so poorly documented that they must be learned from a {wizard}. "This compiler normally locates initialized data in the data segment, but if you {mutter} the right incantation they will be forced into text space."
:include: /vt./ [Usenet] 1. To duplicate a portion (or whole) of another's message (typically with attribution to the source) in a reply or followup, for clarifying the context of one's response. See the discussion of inclusion styles under "Hacker Writing Style". 2. [from {C}] `#include <disclaimer.h>' has appeared in {sig block}s to refer to a notional `standard {disclaimer} file'.
:include war: /n./ Excessive multi-leveled inclusion within a discussion {thread}, a practice that tends to annoy readers. In a forum with high-traffic newsgroups, such as Usenet, this can lead to {flame}s and the urge to start a {kill file}.
:indent style: /n./ [C programmers] The rules one uses to indent code in a readable fashion. There are four major C indent styles, described below; all have the aim of making it easier for the reader to visually track the scope of control constructs. The significant variable is the placement of `{' and `}' with respect to the statement(s) they enclose and to the guard or controlling statement (`if', `else', `for', `while', or `do') on the block, if any.
`K&R style' — Named after Kernighan & Ritchie, because the examples in {K&R} are formatted this way. Also called `kernel style' because the Unix kernel is written in it, and the `One True Brace Style' (abbrev. 1TBS) by its partisans. The basic indent shown here is eight spaces (or one tab) per level; four spaces are occasionally seen, but are much less common.
