way. "Whatcha up to?" "Oh, just hacking." 7. n. Short for {hacker}. 8. See {nethack}. 9. [MIT] v. To explore the basements, roof ledges, and steam tunnels of a large, institutional building, to the dismay of Physical Plant workers and (since this is usually performed at educational institutions) the Campus Police. This activity has been found to be eerily similar to playing adventure games such as Dungeons and Dragons and {Zork}.

See also {vadding}.

Constructions on this term abound. They include `happy hacking'

(a farewell), how's hacking?' (a friendly greeting among hackers) andhack, hack' (a fairly content-free but friendly comment, often used as a temporary farewell). For more on this totipotent term see "{The Meaning of `Hack'}". See also {neat hack}, {real hack}.

:hack attack: [poss. by analogy with Big Mac Attack' from ads for the McDonald's fast-food chain; the variantbig hack attack'

is reported] n. Nearly synonymous with {hacking run}, though the latter more strongly implies an all-nighter.

:hack mode: n. 1. What one is in when hacking, of course. 2. More specifically, a Zen-like state of total focus on The Problem that may be achieved when one is hacking (this is why every good hacker is part mystic). Ability to enter such concentration at will correlates strongly with wizardliness; it is one of the most important skills learned during {larval stage}. Sometimes amplified as `deep hack mode'.

Being yanked out of hack mode (see {priority interrupt}) may be experienced as a physical shock, and the sensation of being in it is more than a little habituating. The intensity of this experience is probably by itself sufficient explanation for the existence of hackers, and explains why many resist being promoted out of positions where they can code. See also {cyberspace}

(sense 2).

Some aspects of hackish etiquette will appear quite odd to an observer unaware of the high value placed on hack mode. For example, if someone appears at your door, it is perfectly okay to hold up a hand (without turning one's eyes away from the screen) to avoid being interrupted. One may read, type, and interact with the computer for quite some time before further acknowledging the other's presence (of course, he or she is reciprocally free to leave without a word). The understanding is that you might be in {hack mode} with a lot of delicate {state} (sense 2) in your head, and you dare not {swap} that context out until you have reached a good point to pause. See also {juggling eggs}.

:hack on: vt. To {hack}; implies that the subject is some pre-existing hunk of code that one is evolving, as opposed to something one might {hack up}.

:hack together: vt. To throw something together so it will work.

Unlike `kluge together' or {cruft together}, this does not necessarily have negative connotations.

:hack up: vt. To {hack}, but generally implies that the result is a hack in sense 1 (a quick hack). Contrast this with {hack on}.

To `hack up on' implies a {quick-and-dirty} modification to an existing system. Contrast {hacked up}; compare {kluge up}, {monkey up}, {cruft together}.

:hack value: n. Often adduced as the reason or motivation for expending effort toward a seemingly useless goal, the point being that the accomplished goal is a hack. For example, MacLISP had features for reading and printing Roman numerals, which were installed purely for hack value. See {display hack} for one method of computing hack value, but this cannot really be explained. As a great artist once said of jazz: "If you hafta ask, you ain't never goin' to find out."

:hack-and-slay: v. (also `hack-and-slash') 1. To play a {MUD}

or go mudding, especially with the intention of {berserking} for pleasure. 2. To undertake an all-night programming/hacking session, interspersed with stints of mudding as a change of pace.

This term arose on the British academic network amongst students who worked nights and logged onto Essex University's MUDs during public-access hours (2 A.M. to 7 A.M.). Usually more mudding than work was done in these sessions.

:hacked off: [analogous to pissed off'] adj. Said of system administrators who have become annoyed, upset, or touchy owing to suspicions that their sites have been or are going to be victimized by crackers, or used for inappropriate, technically illegal, or even overtly criminal activities. For example, having unreadable files in your home directory calledworm', lockpick', orgoroot'

would probably be an effective (as well as impressively obvious and stupid) way to get your sysadmin hacked off at you.

:hacked up: adj. Sufficiently patched, kluged, and tweaked that the surgical scars are beginning to crowd out normal tissue (compare {critical mass}). Not all programs that are hacked become `hacked up'; if modifications are done with some eye to coherence and continued maintainability, the software may emerge better for the experience. Contrast {hack up}.

:hacker: [originally, someone who makes furniture with an axe] n.

A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary. 2. One who programs enthusiastically (even obsessively) or who enjoys programming rather than just theorizing about programming. 3. A person capable of appreciating {hack value}. 4. A person who is good at programming quickly. 5. An expert at a particular program, or one who frequently does work using it or on it; as in `a UNIX

hacker'. (Definitions 1 through 5 are correlated, and people who fit them congregate.) 6. An expert or enthusiast of any kind. One might be an astronomy hacker, for example. 7. One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations. 8. [deprecated] A malicious meddler who tries to discover sensitive information by poking around. Hence password hacker',network hacker'. See {cracker}.

The term `hacker' also tends to connote membership in the global community defined by the net (see {network, the} and {Internet address}). It also implies that the person described is seen to subscribe to some version of the hacker ethic (see {hacker ethic, the}.

It is better to be described as a hacker by others than to describe oneself that way. Hackers consider themselves something of an elite (a meritocracy based on ability), though one to which new members are gladly welcome. There is thus a certain ego satisfaction to be had in identifying yourself as a hacker (but if you claim to be one and are not, you'll quickly be labeled {bogus}). See also {wannabee}.

:hacker ethic, the: n. 1. The belief that information-sharing is a powerful positive good, and that it is an ethical duty of hackers to share their expertise by writing free software and facilitating access to information and to computing resources wherever possible. 2. The belief that system-cracking for fun and exploration is ethically OK as long as the cracker commits no theft, vandalism, or breach of confidentiality.

Both of these normative ethical principles are widely, but by no means universally) accepted among hackers. Most hackers subscribe to the hacker ethic in sense 1, and many act on it by writing and giving away free software. A few go further and assert that all information should be free and any proprietary control of it is bad; this is the philosophy behind the {GNU}

project.

Sense 2 is more controversial: some people consider the act of cracking itself to be unethical, like breaking and entering.

But this principle at least moderates the behavior of people who see themselves as `benign' crackers (see also {samurai}). On this view, it is one of the highest forms of hackerly courtesy to (a) break into a system, and then (b) explain to the sysop, preferably by email from a {superuser} account, exactly how it was done and how the hole can be plugged --- acting as an unpaid (and unsolicited) {tiger team}.

The most reliable manifestation of either version of the hacker ethic is that almost all hackers are actively willing to share technical tricks, software, and (where possible) computing resources with other hackers. Huge cooperative networks such as {USENET}, {Fidonet} and Internet (see {Internet address}) can function without central control because of this trait; they both rely on and reinforce a sense of community that may be hackerdom's most valuable intangible asset.

:hacking run: [analogy with bombing run' orspeed run'] n. A hack session extended long outside normal working times, especially one longer than 12 hours. May cause you to `change phase the hard way' (see {phase}).

:Hacking X for Y: [ITS] n. The information ITS made publicly available about each user (the INQUIR record) was a sort of form in which the user could fill out fields. On display, two of these fields were combined into a project description of the form "Hacking X for Y" (e.g., `"Hacking perceptrons for Minsky"'). This form of description became traditional and has since been carried over to other systems with more general facilities for self-advertisement (such as UNIX {plan file}s).

:Hackintosh: n. 1. An Apple Lisa that has been hacked into emulating a Macintosh (also called a `Mac XL'). 2. A Macintosh assembled from parts theoretically belonging to different models in the line.

:hackish: /hak'ish/ adj. (also {hackishness} n.) 1. Said of something that is or involves a hack. 2. Of or pertaining to hackers or the hacker subculture. See also {true-hacker}.

:hackishness: n. The quality of being or involving a hack. This
