- zap: 1. n. Spiciness. 2. vt. To make food spicy. 3. vt. To make
- someone `suffer' by making his food spicy. (Most hackers love
- spicy food. Hot-and-sour soup is considered wimpy unless it makes
- you wipe your nose for the rest of the meal.) See {zapped}.
- 4. vt. To modify, usually to correct; esp. used when the action
- is performed with a debugger or binary patching tool. Also implies
- surgical precision. "Zap the debug level to 6 and run it again."
- In the IBM mainframe world, binary patches are applied to programs
- or to the OS with a program called `superzap', whose file name is
- `IMASPZAP' (I M A SuPerZAP). 5. vt. To erase or reset. 6. To
- {fry} a chip with static electricity. "Uh oh --- I think that
- lightning strike may have zapped the disk controller."
-
- zapped: adj. Spicy. This term is used to distinguish between food
- that is hot (in temperature) and food that is *spicy*-hot.
- For example, the Chinese appetizer Bon Bon Chicken is a kind of
- chicken salad that is cold but zapped; by contrast, {vanilla}
- wonton soup is hot but not zapped. See also {{oriental food}},
- {laser chicken}. See {zap}, senses 1 and 2.
-
- zen: vt. To figure out something by meditation or by a sudden flash
- of enlightenment. Originally applied to bugs, but occasionally
- applied to problems of life in general. "How'd you figure out the
- buffer allocation problem?" "Oh, I zenned it." Contrast {grok},
- which connotes a time-extended version of zenning a system.
- Compare {hack mode}. See also {guru}.
-
- zero: vt. 1. To set to 0. Usually said of small pieces of data,
- such as bits or words (esp. in the construction `zero out'). 2. To
- erase; to discard all data from. Said of disks and directories,
- where `zeroing' need not involve actually writing zeroes throughout
- the area being zeroed. One may speak of something being
- `logically zeroed' rather than being `physically zeroed'. See
- {scribble}.
-
- zero-content: adj. Syn. {content-free}.
-
- zeroth: /zee'rohth/ adj. First. Among software designers, comes
- from C's and LISP's 0-based indexing of arrays. Hardware people
- also tend to start counting at 0 instead of 1; this is natural
- since, e.g., the 256 states of 8 bits correspond to the binary
- numbers 0, 1, ..., 255 and the digital devices known as `counters'
- count in this way.
-
- Hackers and computer scientists often like to call the first
- chapter of a publication `chapter 0', especially if it is of an
- introductory nature (one of the classic instances was in the First
- Edition of {K&R}). In recent years this trait has also been
- observed among many pure mathematicians (who have an independent
- tradition of numbering from 0). Zero-based numbering tends to
- reduce {fencepost error}s, though it cannot eliminate them
- entirely.
-
- zigamorph: /zig'*-morf/ n. Hex FF (11111111) when used as a
- delimiter or {fence} character. Usage: primarily at IBM
- shops.
-
- zip: [primarily MS-DOS] vt. To create a compressed archive from a
- group of files using PKWare's PKZIP or a compatible archiver. Its
- use is spreading now that portable implementations of the algorithm
- have been written. Commonly used as follows: "I'll zip it up and
- send it to you." See {arc}, {tar and feather}.
-
- zipperhead: [IBM] n. A person with a closed mind.
-
- zombie: [UNIX] n. A process that has died but has not yet
- relinquished its process table slot (because the parent process
- hasn't executed a `wait(2)' for it yet). These can be seen in
- `ps(1)' listings occasionally. Compare {orphan}.
-
- zorch: /zorch/ 1. [TMRC] v. To attack with an inverse heat sink.
- 2. [TMRC] v. To travel, with v approaching c [that
- is, with velocity approaching lightspeed --- ESR]. 3. [MIT] v. To
- propel something very quickly. "The new comm software is very
- fast; it really zorches files through the network." 4. [MIT] n.
- Influence. Brownie points. Good karma. The intangible and fuzzy
- currency in which favors are measured. "I'd rather not ask him
- for that just yet; I think I've used up my quota of zorch with him
- for the week." 5. [MIT] n. Energy, drive, or ability. "I think
- I'll {punt} that change for now; I've been up for 30 hours
- and I've run out of zorch."
-
- Zork: /zork/ n. The second of the great early experiments in computer
- fantasy gaming; see {ADVENT}. Originally written on MIT-DM
- during the late 1970s, later distributed with BSD UNIX and
- commercialized as `The Zork Trilogy' by Infocom.
-
- zorkmid: /zork'mid/ n. The canonical unit of currency in
- hacker-written games. This originated in {zork} but has spread
- to {nethack} and is referred to in several other games.
