{trivial}, {uninteresting}.

:Internet address:: n. 1. [techspeak] An absolute network address of the form foo@bar.baz, where foo is a user name, bar is a {sitename}, and baz is a `domain' name, possibly including periods itself. Contrast with {bang path}; see also {network, the} and {network address}. All Internet machines and most UUCP

sites can now resolve these addresses, thanks to a large amount of behind-the-scenes magic and PD software written since 1980 or so.

See also {bang path}, {domainist}. 2. More loosely, any network address reachable through Internet; this includes {bang path} addresses and some internal corporate and government networks.

Reading Internet addresses is something of an art. Here are the four most important top-level functional Internet domains followed by a selection of geographical domains: com

commercial organizations edu educational institutions gov U.S. government civilian sites mil U.S. military sites

Note that most of the sites in the com and edu domains are in the U.S. or Canada.

us sites in the U.S. outside the functional domains su sites in the ex-Soviet Union (see {kremvax}). uk sites in the United Kingdom

Within the us domain, there are subdomains for the fifty states, each generally with a name identical to the state's postal abbreviation. Within the uk domain, there is an ac subdomain for academic sites and a co domain for commercial ones. Other top-level domains may be divided up in similar ways.

:interrupt: 1. [techspeak] n. On a computer, an event that interrupts normal processing and temporarily diverts flow-of-control through an "interrupt handler" routine. See also {trap}. 2. interj. A request for attention from a hacker.

Often explicitly spoken. "Interrupt --- have you seen Joe recently?" See {priority interrupt}. 3. Under MS-DOS, the term interrupt' is nearly synonymous withsystem call', because the OS and BIOS routines are both called using the INT instruction (see {{interrupt list, the}}) and because programmers so often have to bypass the OS (going directly to a BIOS interrupt) to get reasonable performance.

:interrupt list, the:: [MS-DOS] n. The list of all known software interrupt calls (both documented and undocumented) for IBM PCs and compatibles, maintained and made available for free redistribution by Ralf Brown ralf@cs.cmu.edu. As of early 1991, it had grown to approximately a megabyte in length.

:interrupts locked out: adj. When someone is ignoring you. In a restaurant, after several fruitless attempts to get the waitress's attention, a hacker might well observe "She must have interrupts locked out". The synonym `interrupts disabled' is also common.

Variations abound; "to have one's interrupt mask bit set" and "interrupts masked out" is also heard. See also {spl}.

:IRC: /I-R-C/ [Internet Relay Chat] n. A world-wide "party line" network that allows one to converse with others in real time. IRC is structured as a network of Internet servers, each of which accepts connections from client programs, one per user. The IRC community and the {USENET} and {MUD} communities overlap to some extent, including both hackers and regular folks who have discovered the wonders of computer networks. Some USENET jargon has been adopted on IRC, as have some conventions such as {emoticon}s. There is also a vigorous native jargon, represented in this lexicon by entries marked `[IRC]'. See also {talk mode}.

:iron: n. Hardware, especially older and larger hardware of {mainframe} class with big metal cabinets housing relatively low-density electronics (but the term is also used of modern supercomputers). Often in the phrase {big iron}. Oppose {silicon}. See also {dinosaur}.

:Iron Age: n. In the history of computing, 1961--1971 --- the formative era of commercial {mainframe} technology, when {big iron} {dinosaur}s ruled the earth. These began with the delivery of the first PDP-1, coincided with the dominance of ferrite {core}, and ended with the introduction of the first commercial microprocessor (the Intel 4004) in 1971. See also {Stone Age}; compare {elder days}.

:iron box: [UNIX/Internet] n. A special environment set up to trap a {cracker} logging in over remote connections long enough to be traced. May include a modified {shell} restricting the cracker's movements in unobvious ways, and bait' files designed to keep him interested and logged on. See also {back door}, {firewall machine}, {Venus flytrap}, and Clifford Stoll's account in{The Cuckoo's Egg}' of how he made and used one (see the Bibliography in appendix C). Compare {padded cell}.

:ironmonger: [IBM] n. Derogatory. A hardware specialist. Compare {sandbender}, {polygon pusher}.

:ITS:: /I-T-S/ n. 1. Incompatible Time-sharing System, an influential but highly idiosyncratic operating system written for PDP-6s and PDP-10s at MIT and long used at the MIT AI Lab. Much AI-hacker jargon derives from ITS folklore, and to have been an ITS hacker' qualifies one instantly as an old-timer of the most venerable sort. ITS pioneered many important innovations, including transparent file sharing between machines and terminal-independent I/O. After about 1982, most actual work was shifted to newer machines, with the remaining ITS boxes run essentially as a hobby and service to the hacker community. The shutdown of the lab's last ITS machine in May 1990 marked the end of an era and sent old-time hackers into mourning nationwide (see {high moby}). The Royal Institute of Technology in Sweden is maintaining onelive' ITS site at its computer museum (right next to the only TOPS-10 system still on the Internet), so ITS is still alleged to hold the record for OS in longest continuous use (however, {{WAITS}} is a credible rival for this palm). See {appendix A}. 2. A mythical image of operating-system perfection worshiped by a bizarre, fervent retro-cult of old-time hackers and ex-users (see {troglodyte}, sense 2). ITS worshipers manage somehow to continue believing that an OS maintained by assembly-language hand-hacking that supported only monocase 6-character filenames in one directory per account remains superior to today's state of commercial art (their venom against UNIX is particularly intense). See also {holy wars}, {Weenix}.

:IWBNI: // [abbreviation] `It Would Be Nice If'. Compare {WIBNI}.

:IYFEG: // [USENET] Abbreviation for `Insert Your Favorite Ethnic Group'. Used as a meta-name when telling racist jokes on the net to avoid offending anyone. See {JEDR}.

:J. Random: /J rand'm/ n. [generalized from {J. Random Hacker}]

Arbitrary; ordinary; any one; any old. J. Random' is often prefixed to a noun to make a name out of it. It means roughlysome particular' or any specific one'. "Would you let J. Random Loser marry your daughter?" The most common uses areJ. Random Hacker', J. Random Loser', andJ. Random Nerd'

("Should J. Random Loser be allowed to {gun} down other people?"), but it can be used simply as an elaborate version of {random} in any sense.

:J. Random Hacker: [MIT] /J rand'm hak'r/ n. A mythical figure like the Unknown Soldier; the archetypal hacker nerd. See {random}, {Suzie COBOL}. This may originally have been inspired by J. Fred Muggs', a show-biz chimpanzee whose name was a household word back in the early days of {TMRC}, and was probably influenced byJ. Presper Eckert' (one of the co-inventors of the digital computer).

:jack in: v. To log on to a machine or connect to a network or {BBS}, esp. for purposes of entering a {virtual reality}

simulation such as a {MUD} or {IRC} (leaving is "jacking out"). This term derives from {cyberpunk} SF, in which it was used for the act of plugging an electrode set into neural sockets in order to interface the brain directly to a virtual reality.

It's primarily used by MUD & IRC fans and younger hackers on BBS

systems.

:jaggies: /jag'eez/ n. The `stairstep' effect observable when an edge (esp. a linear edge of very shallow or steep slope) is rendered on a pixel device (as opposed to a vector display).

:JCL: /J-C-L/ n. 1. IBM's supremely {rude} Job Control Language. JCL is the script language used to control the execution of programs in IBM's batch systems. JCL has a very {fascist}

syntax, and some versions will, for example, {barf} if two spaces appear where it expects one. Most programmers confronted with JCL simply copy a working file (or card deck), changing the file names. Someone who actually understands and generates unique JCL is regarded with the mixed respect one gives to someone who memorizes the phone book. It is reported that hackers at IBM

itself sometimes sing "Who's the breeder of the crud that mangles you and me? I-B-M, J-C-L, M-o-u-s-e" to the tune of the "Mickey Mouse Club" theme to express their opinion of the beast. 2. A comparative for any very {rude} software that a hacker is expected to use. "That's as bad as JCL." As with {COBOL}, JCL is often used as an archetype of ugliness even by those who haven't experienced it. See also {IBM}, {fear and loathing}.

:JEDR: // n. Synonymous with {IYFEG}. At one time, people in the USENET newsgroup rec.humor.funny tended to use `JEDR'

instead of {IYFEG} or <ethnic>'; this stemmed from a public attempt to suppress the group once made by a loser with initials JEDR after he was offended by an ethnic joke posted there. (The practice was {retcon}ned by the expanding these initials asJoke Ethnic/Denomination/Race'.) After much
