--- when necessary to eliminate oral ambiguity. To read aloud the LISP form (DEFUN FOO (X) (PLUS X 1)) one might say: "Open def-fun foo, open eks close, open, plus eks one, close close." See CLOSE. PARSE [from linguistic terminology] v. 1. To determine the syntactic structure of a sentence or other utterance (close to the standard English meaning). Example: "That was the one I saw you." "I can't parse that." 2. More generally, to understand or comprehend. "It's very sim- ple; you just kretch the glims and then aos the zotz." "I can't parse that." 3. Of fish, to have to remove the - 24 - bones yourself (usually at a Chinese restaurant). "I object to parsing fish" means "I don't want to get a whole fish, but a sliced one is okay." A "parsed fish" has been deboned. There is some controversy over whether "unparsed" should mean "bony," or also mean "deboned." PATCH 1. n. A temporary addition to a piece of code, usually as a quick-and-dirty remedy to an existing bug or mis- feature. A patch may or may not work, and may or may not eventually be incorporated permanently into the pro- gram. 2. v. To insert a patch into a piece of code. PDL (piddle or puddle) [acronym for Push Down List] n. 1. A LIFO queue (stack); more loosely, any priority queue; even more loosely, any queue. A person's pdl is the set of things he has to do in the future. One speaks of the next project to be attacked as having risen to the top of the pdl. "I'm afraid I've got real work to do, so this'll have to be pushed way down on my pdl." See PUSH and POP. 2. Dave Lebling (PDL@DM). PESSIMAL [Latin-based antonym for "optimal"] adj. Maximally bad. "This is a pessimal situation." PESSIMIZING COMPILER n. A compiler that produces object code that is worse than the straightforward or obvious trans- lation. PHANTOM n. (Stanford) The SAIL equivalent of a DRAGON (q.v.). Typical phantoms include the accounting pro- gram, the news-wire monitor, and the lpt and xgp spoolers. PHASE (of people) 1. n. The phase of one's waking-sleeping schedule with respect to the standard 24-hour cycle. This is a useful concept among people who often work at night according to no fixed schedule. It is not uncom- mon to change one's phase by as much as six hours/day on a regular basis. "What's your phase?" "I've been get- ting in about 8 PM lately, but I'm going to work around to the day schedule by Friday." A person who is roughly 12 hours out of phase is sometimes said to be in "night mode." (The term "day mode" is also used, but less fre- quently.) 2. CHANGE PHASE THE HARD WAY: To stay awake for a very long time in order to get into a different phase. 3. CHANGE PHASE THE EASY WAY: To stay asleep etc. PHASE OF THE MOON n. Used humorously as a random parameter on which something is said to depend. Sometimes implies unreliability of whatever is dependent, or that relia- bility seems to be dependent on conditions nobody has been able to determine. "This feature depends on having - 25 - the channel open in mumble mode, having the foo switch set, and on the phase of the moon." PLUGH [from the Adventure game] v. See XYZZY. POM n. Phase of the moon (q.v.). Usage: usually used in the phrase "POM dependent" which means flakey (q.v.). POP [based on the stack operation that removes the top of a stack, and the fact that procedure return addresses are saved on the stack] dialect: POPJ (pop-jay), based on the PDP-10 procedure return instruction. v. To return from a digression. By verb doubling, "Popj, popj" means roughly, "Now let's see, where were we?" PPN (pip'in) [DEC terminology, short for Project-Programmer Number] n. 1. A combination "project" (directory name) and programmer name, used to identify a specific direc- tory belonging to that user. For instance, "FOO,BAR" would be the FOO directory for user BAR. Since the name is restricted to three letters, the programmer name is usually the person's initials, though sometimes it is a nickname or other special sequence. (Standard DEC setup is to have two octal numbers instead of characters; hence the original acronym.) 2. Often used loosely to refer to the programmer name alone. "I want to send you some mail; what's your ppn?" Usage: not used at MIT, since ITS does not use ppn's. The equivalent terms would be UNAME and SNAME, depending on context, but these are not used except in their technical senses. PROTOCOL See DO PROTOCOL. PSEUDOPRIME n. A backgammon prime (six consecutive occupied points) with one point missing. PTY (pity) n. Pseudo TTY, a simulated TTY used to run a job under the supervision of another job. PTYJOB (pity-job) n. The job being run on the PTY. Also a common general-purpose program for creating and using PTYs. This is DEC and SAIL terminology; the MIT equivalent is STY. PUNT [from the punch line of an old joke: "Drop back 15 yards and punt"] v. To give up, typically without any intention of retrying. PUSH [based on the stack operation that puts the current information on a stack, and the fact that procedure call addresses are saved on the stack] dialect: PUSHJ (push- jay), based on the PDP-10 procedure call instruction. v. To enter upon a digression, to save the current dis- cussion for later. - 26 - QUES (kwess) 1. n. The question mark character ("?"). 2. interj. What? Also QUES QUES? See WALL. QUUX [invented by Steele. Mythically, from the Latin semi- deponent verb QUUXO, QUUXARE, QUUXANDUM IRI; noun form variously QUUX (plural QUUCES, Anglicized to QUUXES) and QUUXU (genitive plural is QUUXUUM, four U's in seven letters).] 1. Originally, a meta-word like FOO and FOOBAR. Invented by Guy Steele for precisely this pur- pose when he was young and naive and not yet interacting with the real computing community. Many people invent such words; this one seems simply to have been lucky enough to have spread a little. 2. interj. See FOO; however, denotes very little disgust, and is uttered mostly for the sake of the sound of it. 3. n. Refers to one of four people who went to Boston Latin School and eventually to MIT: THE GREAT QUUX: Guy L. Steele, Jr. THE LESSER QUUX: David J. Littleboy THE MEDIOCRE QUUX: Alan P. Swide THE MICRO QUUX: Sam Lewis (This taxonomy is said to be similarly applied to three Frankston brothers at MIT.) QUUX, without qualifica- tion, usually refers to The Great Quux, who is somewhat infamous for light verse and for the "Crunchly" car- toons. 4. QUUXY: adj. Of or pertaining to a QUUX. RANDOM adj. 1. Unpredictable (closest to mathematical defin- ition); weird. "The system's been behaving pretty ran- domly." 2. Assorted; undistinguished. "Who was at the conference?" "Just a bunch of random business types." 3. Frivolous; unproductive; undirected (pejorative). "He's just a random loser." 4. Incoherent or inelegant; not well organized. "The program has a random set of mis- features." "That's a random name for that function." "Well, all the names were chosen pretty randomly." 5. Gratuitously wrong, i.e., poorly done and for no good apparent reason. For example, a program that handles file name defaulting in a particularly useless way, or a routine that could easily have been coded using only three ac's, but randomly uses seven for assorted non- overlapping purposes, so that no one else can invoke it without first saving four extra ac's. 6. In no particu- lar order, though deterministic. "The I/O channels are in a pool, and when a file is opened one is chosen ran- domly." n. 7. A random hacker; used particularly of high school students who soak up computer time and generally get in the way. 8. (occasional MIT usage) One who lives at Random Hall. J. RANDOM is often prefixed to a noun to make a "name" out of it (by comparison to common names such as "J. Fred Muggs"). The most common uses are "J. Random Loser" and "J. Random Nurd" ("Should J. - 27 - Random Loser be allowed to gun down other people?"), but it can be used just as an elaborate version of RANDOM in any sense. [See also the note at the end of the entry for HACK.] RANDOMNESS n. An unexplainable misfeature; gratuitous inelegance. Also, a hack or crock which depends on a complex combination of coincidences (or rather, the com- bination upon which the crock depends). "This hack can output characters 40-57 by putting the character in the accumulator field of an XCT and then extracting 6 bits -- the low two bits of the XCT opcode are the right thing." "What randomness!" RAPE v. To (metaphorically) screw someone or something, violently. Usage: often used in describing file-system damage. "So-and-so was running a program that did abso- lute disk I/O and ended up raping the master directory." RAVE (WPI) v. 1. To persist in discussing a specific sub- ject. 2. To speak authoritatively on a subject about which one knows very little. 3. To complain to a person who is not in a position to correct the difficulty. 4. To purposely annoy another person verbally. 5. To evangelize. See FLAME. Also used to describe a less negative form of blather, such as friendly bullshitting. REAL USER n. 1. A commercial user. One who is paying "real" money for his computer usage. 2. A non-hacker. Someone using the system for an explicit purpose (research pro- ject, course, etc.). See USER. REAL WORLD, THE n. 1. In programming, those institutions at which programming may be used in the same sentence as FORTRAN, COBOL, RPG, IBM, etc. 2. To programmers, the location of non-programmers and activities not related to programming. 3. A universe in which the standard dress is shirt and tie and in which a person's working hours are defined as 9 to 5. 4. The location of the status quo. 5. Anywhere outside a university. "Poor fellow, he's left MIT and gone into the real world." Used pejoratively by those not in residence there. In conversation, talking of someone who has entered the real world is not unlike talking about a deceased per- son. RECURSION n. See RECURSION, TAIL RECURSION. REL See BIN. RIGHT THING, THE n. That which is "obviously" the correct or appropriate thing to use, do, say, etc. Use of this term often implies that in fact reasonable people may disagree. "Never let your conscience keep you from - 28 - doing the right thing!" "What's the right thing for LISP to do when it reads '(.)'?" RUDE (WPI) adj. 1. (of a program) Badly written. 2. Func- tionally poor, e.g. a program which is very difficult to use because of gratuitously poor (random?) design deci- sions. See CUSPY. SACRED adj. Reserved for the exclusive use of something (a metaphorical extension of the standard meaning). "Accu- mulator 7 is sacred to the UUO handler." Often means that anyone may look at the sacred object, but clobber- ing it will screw whatever it is sacred to. SAGA (WPI) n. A cuspy but bogus raving story dealing with N random broken people. SAV (save) See BIN. SEMI 1. n. Abbreviation for "semicolon," when speaking. "Commands to GRIND are prefixed by semi-semi-star" means that the prefix is ";;*", not 1/4 of a star. 2. Prefix with words such as "immediately," as a qualifier. "When is the system coming up?" "Semi-immediately." SERVER n. A kind of DAEMON which performs a service for the requester, which often runs on a computer other than the one on which the server runs. SHIFT LEFT (RIGHT) LOGICAL [from any of various machines' instruction sets] 1. v. To move oneself to the left (right). To move out of the way. 2. imper. Get out of that (my) seat! Usage: often used without the "logi- cal," or as "left shift" instead of "shift left." Some- times heard as LSH (lish), from the PDP-10 instruction set. SHR (share or shir) See BIN. SHRIEK See EXCL. (Occasional CMU usage.) 69 adj. Large quantity. Usage: Exclusive to MIT-AI. "Go away, I have 69 things to do to DDT before worrying about fixing the bug in the phase of the moon output routine." [Note: Actually, any number less than 100 but large enough to have no obvious magic properties will be recognized as a "large number." There is no denying that "69" is the local favorite. I don't know whether its origins are related to the obscene interpretation, but I do know that 69 decimal = 105 octal, and 69 hexadecimal = 105 decimal, which is a nice property. --GLS] SLOP n. 1. A one-sided fudge factor (q.v.). Often intro- duced to avoid the possibility of a fencepost error - 29 - (q.v.). 2. (used by compiler freaks) The ratio of code generated by a compiler to hand-compiled code, minus 1; i.e., the space (or maybe time) you lose because you didn't do it yourself. SLURP v. To read a large data file entirely into core before working on it. "This program slurps in a 1K-by-1K matrix and does an FFT." SMART adj. Said of a program that does the Right Thing (q.v.) in a wide variety of complicated circumstances. There is a difference between calling a program smart and calling it intelligent; in particular, there do not exist any intelligent programs. SMOKING CLOVER n. A psychedelic color munch due to Gosper. SMOP [Simple (or Small) Matter of Programming] n. A piece of code, not yet written, whose anticipated length is sig- nificantly greater than its complexity. Usage: used to refer to a program that could obviously be written, but is not worth the trouble. SNARF v. To grab, esp. a large document or file for the pur- pose of using it either with or without the author's permission. See BLT. Variant: SNARF (IT) DOWN. (At MIT on ITS, DDT has a command called :SNARF which grabs a job from another (inferior) DDT.) SOFTWARE ROT n. Hypothetical disease the existence of which has been deduced from the observation that unused pro- grams or features will stop working after sufficient time has passed, even if "nothing has changed." Also known as "bit decay." SOFTWARILY adv. In a way pertaining to software. "The sys- tem is softwarily unreliable." The adjective "softwary" is NOT used. See HARDWARILY. SOS 1. (ess-oh-ess) n. A losing editor, SON OF STOPGAP. 2. (sahss) v. Inverse of AOS, from the PDP-10 instruction set. SPAZZ 1. v. To behave spastically or erratically; more often, to commit a single gross error. "Boy, is he spazzing!" 2. n. One who spazzes. "Boy, what a spazz!" 3. n. The result of spazzing. "Boy, what a spazz!" SPLAT n. 1. Name used in many places (DEC, IBM, and others) for the ASCII star ("*") character. 2. (MIT) Name used by some people for the ASCII pound-sign ("#") character. 3. (Stanford) Name used by some people for the Stanford/ITS extended ASCII circle-x character. (This character is also called "circle-x," "blobby," and - 30 - "frob," among other names.) 4. (Stanford) Name for the semi-mythical extended ASCII circle-plus character. 5. Canonical name for an output routine that outputs what- ever the the local interpretation of splat is. Usage: nobody really agrees what character "splat" is, but the term is common. SUPDUP v. To communicate with another ARPAnet host using the SUPDUP program, which is a SUPer-DUPer TELNET talking a special display protocol used mostly in talking to ITS sites. Sometimes abbreviated to SD. STATE n. Condition, situation. "What's the state of NEWIO?" "It's winning away." "What's your state?" "I'm about to gronk out." As a special case, "What's the state of the world?" (or, more silly, "State-of-world-P?") means "What's new?" or "What's going on?" STOPPAGE n. Extreme lossage (see LOSSAGE) resulting in some- thing (usually vital) becoming completely unusable. STY (pronounced "sty," not spelled out) n. A pseudo- teletype, which is a two-way pipeline with a job on one end and a fake keyboard-tty on the other. Also, a stan- dard program which provides a pipeline from its control- ling tty to a pseudo-teletype (and thence to another tty, thereby providing a "sub-tty"). This is MIT termi- nology; the SAIL and DEC equivalent is PTY. SUPERPROGRAMMER n. See "wizard," "hacker." Usage: rare. (Becoming more common among IBM and Yourdon types.) SWAPPED adj. From the use of secondary storage devices to implement virtual memory in computer systems. Something which is SWAPPED IN is available for immediate use in main memory, and otherwise is SWAPPED OUT. Often used metaphorically to refer to people's memories ("I read TECO ORDER every few months to keep the information swapped in.") or to their own availability ("I'll swap you in as soon as I finish looking at this other prob- lem."). SYSTEM n. 1. The supervisor program on the computer. 2. Any large-scale program. 3. Any method or algorithm. 4. The way things are usually done. Usage: a fairly ambi- guous word. "You can't beat the system." SYSTEM HACKER: one who hacks the system (in sense 1 only; for sense 2 one mentions the particular program: e.g., LISP HACKER) T [from LISP terminology for "true"] 1. Yes. Usage: used in reply to a question, particularly one asked using the "-P" convention). See NIL. 2. See TIME T. TAIL RECURSION n. See TAIL RECURSION. - 31 - TALK MODE See COM MODE. TASTE n. (primarily MIT-DMS) The quality in programs which tends to be inversely proportional to the number of features, hacks, and kluges programmed into it. Also, TASTY, TASTEFUL, TASTEFULNESS. "This feature comes in N tasty flavors." Although TASTEFUL and FLAVORFUL are essentially synonyms, TASTE and FLAVOR are not. TECO (tee'koe) [acronym for Text Editor and COrrector] 1. n. A text editor developed at MIT, and modified by just about everybody. If all the dialects are included, TECO might well be the single most prolific editor in use. Noted for its powerful pseudo-programming features and its incredibly hairy syntax. 2. v. To edit using the TECO editor in one of its infinite forms; sometimes used to mean "to edit" even when not using TECO! Usage: rare at SAIL, where most people wouldn't touch TECO with a TENEX pole. [Historical note: DEC grabbed an ancient version of MIT TECO many years ago when it was still a TTY-oriented editor. By now, TECO at MIT is highly display-oriented and is actually a language for writing editors, rather than an editor. Meanwhile, the outside world's various versions of TECO remain almost the same as the MIT version of ten years ago. DEC recently tried to discourage its use, but an underground movement of sorts kept it alive.] [Since this note was written I found out that DEC tried to force their hackers by administrative decision to use a hacked up and generally lobotomized version of SOS instead of TECO, and they revolted. --MRC] TELNET v. To communicate with another ARPAnet host using the TELNET protocol. TOPS-10 people use the word IMPCOM since that is the program name for them. Sometimes abbreviated to TN. "I usually TN over to SAIL just to read the AP News." TENSE adj. Of programs, very clever and efficient. A tense piece of code often got that way because it was highly bummed, but sometimes it was just based on a great idea. A comment in a clever display routine by Mike Kazar: "This routine is so tense it will bring tears to your eyes. Much thanks to Craig Everhart and James Gosling for inspiring this hack attack." A tense programmer is one who produces tense code. TERPRI (tur'pree) [from the LISP 1.5 (and later, MacLISP) function to start a new line of output] v. To output a CRLF (q.v.). THEORY n. Used in the general sense of idea, plan, story, or set of rules. "What's the theory on fixing this TECO loss?" "What's the theory on dinner tonight?" - 32 - ("Chinatown, I guess.") "What's the current theory on letting losers on during the day?" "The theory behind this change is to fix the following well-known screw..." THRASH v. To move wildly or violently, without accomplishing anything useful. Swapping systems which are overloaded waste most of their time moving pages into and out of core (rather than performing useful computation), and are therefore said to thrash. TICK n. 1. Interval of time; basic clock time on the com- puter. Typically 1/60 second. See JIFFY. 2. In simu- lations, the discrete unit of time that passes "between" iterations of the simulation mechanism. In AI applica- tions, this amount of time is often left unspecified, since the only constraint of interest is that caused things happen after their causes. This sort of AI simu- lation is often pejoratively referred to as "tick-tick- tick" simulation, especially when the issue of simul- taneity of events with long, independent chains of causes is handwaved. TIME T n. 1. An unspecified but usually well-understood time, often used in conjunction with a later time T+1. "We'll meet on campus at time T or at Louie's at time T+1." 2. SINCE (OR AT) TIME T EQUALS MINUS INFINITY: A long time ago; for as long as anyone can remember; at the time that some particular frob was first designed. TOOL v.i. To work; to study. See HACK (def #9). TRAP 1. n. A program interrupt, usually used specifically to refer to an interrupt caused by some illegal action tak- ing place in the user program. In most cases the system monitor performs some action related to the nature of the illegality, then returns control to the program. See UUO. 2. v. To cause a trap. "These instructions trap to the monitor." Also used transitively to indicate the cause of the trap. "The monitor traps all input/output instructions." TTY (titty) n. Terminal of the teletype variety, character- ized by a noisy mechanical printer, a very limited char- acter set, and poor print quality. Usage: antiquated (like the TTY's themselves). Sometimes used to refer to any terminal at all; sometimes used to refer to the par- ticular terminal controlling a job. TWEAK v. To change slightly, usually in reference to a value. Also used synonymously with TWIDDLE. See FROB- NICATE and FUDGE FACTOR. TWENEX n. The TOPS-20 operating system by DEC. So named because TOPS-10 was a typically crufty DEC operating - 33 - system for the PDP-10. BBN developed their own system, called TENEX (TEN EXecutive), and in creating TOPS-20 for the DEC-20 DEC copied TENEX and adapted it for the 20. Usage: DEC people cringe when they hear TOPS-20 referred to as "Twenex," but the term seems to be catch- ing on nevertheless. Release 3 of TOPS-20 is suffi- ciently different from release 1 that some (not all) hackers have stopped calling it TWENEX, though the writ- ten abbreviation "20x" is still used. TWIDDLE n. 1. tilde (ASCII 176, "~"). Also called "squig- gle," "sqiggle" (sic--pronounced "skig'gul"), and "twad- dle," but twiddle is by far the most common term. 2. A small and insignificant change to a program. Usually fixes one bug and generates several new ones. 3. v. To change something in a small way. Bits, for example, are often twiddled. Twiddling a switch or knob implies much less sense of purpose than toggling or tweaking it; see FROBNICATE. UP adj. 1. Working, in order. "The down escalator is up." 2. BRING UP: v. To create a working version and start it. "They brought up a down system." USER n. A programmer who will believe anything you tell him. One who asks questions. Identified at MIT with "loser" by the spelling "luser." See REAL USER. [Note by GLS: I don't agree with RF's definition at all. Basically, there are two classes of people who work with a program: there are implementors (hackers) and users (losers). The users are looked down on by hackers to a mild degree because they don't understand the full ramifications of the system in all its glory. (A few users who do are known as real winners.) It is true that users ask ques- tions (of necessity). Very often they are annoying or downright stupid.] UUO (you-you-oh) [short for "Un-Used Operation"] n. A DEC-10 system monitor call. The term "Un-Used Operation" comes from the fact that, on DEC-10 systems, monitor calls are implemented as invalid or illegal machine instructions, which cause traps to the monitor (see TRAP). The SAIL manual describing the available UUO's has a cover pic- ture showing an unidentified underwater object. See YOYO. [Note: DEC sales people have since decided that "Un-Used Operation" sounds bad, so UUO now stands for "Unimplemented User Operation."] Tenex and Twenex sys- tems use the JSYS machine instruction (q.v.), which is halfway between a legal machine instruction and a UUO, since KA-10 Tenices implement it as a hardware instruc- tion which can be used as an ordinary subroutine call (sort of a "pure JSR"). VANILLA adj. Ordinary flavor, standard. See FLAVOR. When - 34 - used of food, very often does not mean that the food is flavored with vanilla extract! For example, "vanilla- flavored wonton soup" (or simply "vanilla wonton soup") means ordinary wonton soup, as opposed to hot and sour wonton soup. VAXEN [from "oxen," perhaps influenced by "vixen"] n. pl. The plural of VAX (a DEC machine). VIRGIN adj. Unused, in reference to an instantiation of a program. "Let's bring up a virgin system and see if it crashes again." Also, by extension, unused buffers and the like within a program. VIRTUAL adj. 1. Common alternative to LOGICAL (q.v.), but never used with compass directions. 2. Performing the functions of. Virtual memory acts like real memory but isn't. VISIONARY n. One who hacks vision (in an AI context, such as the processing of visual images). WALDO [probably taken from the story "Waldo," by Heinlein, which is where the term was first used to mean a mechan- ical adjunct to a human limb] Used at Harvard, particu- larly by Tom Cheatham and students, instead of FOOBAR as a meta-syntactic variable and general nonsense word. See FOO, BAR, FOOBAR, QUUX. WALL [shortened form of HELLO WALL, apparently from the phrase "up against a blank wall"] (WPI) interj. 1. An indication of confusion, usually spoken with a quizzical tone. "Wall??" 2. A request for further explication. WALLPAPER n. A file containing a listing (e.g., assembly listing) or transcript, esp. a file containing a tran- script of all or part of a login session. (The idea was that the LPT paper for such listings was essentially good only for wallpaper, as evidenced at SAIL where it was used as such to cover windows.) Usage: not often used now, esp. since other systems have developed other terms for it (e.g., PHOTO on TWENEX). The term possibly originated on ITS, where the commands to begin and end transcript files are still :WALBEG and :WALEND, with default file DSK:WALL PAPER. WATERBOTTLE SOCCER n. A deadly sport practiced mainly by Sussman's graduate students. It, along with chair bowl- ing, is the most evident manifestation of the "locker room atmosphere" said to reign in that sphere. (Sussman doesn't approve.) [As of 11/82, it's reported that the sport has given way to a new game called "disc-boot," and Sussman even participates occasionally.] - 35 - WEDGED [from "head wedged up ass"] adj. To be in a locked state, incapable of proceeding without help. (See GRONK.) Often refers to humans suffering misconcep- tions. "The swapper is wedged." This term is sometimes used as a synonym for DEADLOCKED (q.v.). WHAT n. The question mark character ("?"). See QUES. Usage: rare, used particularly in conjunction with WOW. WHEEL n. 1. A privilege bit that canonically allows the pos- sessor to perform any operation on a timesharing system, such as read or write any file on the system regardless of protections, change or or look at any address in the running monitor, crash or reload the system, and kill/create jobs and user accounts. The term was invented on the TENEX operating system, and carried over to TOPS-20, Xerox-IFS and others. 2. A person who posses a wheel bit. "We need to find a wheel to unwedge the hung tape drives." WHEEL WARS [from LOTS at Stanford University] A period dur- ing which student wheels hack each other by attempting to log each other out of the system, delete each other's files, or otherwise wreak havoc, usually at the expense of the lesser users. WIN [from MIT jargon] 1. v. To succeed. A program wins if no unexpected conditions arise. 2. BIG WIN: n. Serendi- pity. Emphatic forms: MOBY WIN, SUPER WIN, HYPER-WIN (often used interjectively as a reply). For some reason SUITABLE WIN is also common at MIT, usually in reference to a satisfactory solution to a problem. See LOSE. WINNAGE n. The situation when a lossage is corrected, or when something is winning. Quite rare. Usage: also quite rare. WINNER 1. n. An unexpectedly good situation, program, pro- grammer or person. 2. REAL WINNER: Often sarcastic, but also used as high praise. WINNITUDE n. The quality of winning (as opposed to WINNAGE, which is the result of winning). "That's really great! Boy, what winnitude!" WIZARD n. 1. A person who knows how a complex piece of software or hardware works; someone who can find and fix his bugs in an emergency. Rarely used at MIT, where HACKER is the preferred term. 2. A person who is per- mitted to do things forbidden to ordinary people, e.g., a "net wizard" on a TENEX may run programs which speak low-level host-imp protocol; an ADVENT wizard at SAIL may play Adventure during the day. - 36 - WORMHOLE n. A location in a monitor which contains the address of a routine, with the specific intent of making it easy to substitute a different routine. The follow- ing quote comes from "Polymorphic Systems," vol. 2, p. 54: "Any type of I/O device can be substituted for the stan- dard device by loading a simple driver routine for that device and installing its address in one of the monitor's __________ *The term has been used to describe a hypothetical astronomical situation where a black hole connects to the of the universe. When this happens, information can pass through the wormhole, in only one direction, much as pass down the monitor's wormholes." WOW See EXCL. XGP 1. n. Xerox Graphics Printer. 2. v. To print something on the XGP. "You shouldn't XGP such a large file." XYZZY [from the Adventure game] adj. See PLUGH. YOYO n. DEC service engineers' slang for UUO (q.v.). Usage: rare at Stanford and MIT, has been found at random DEC installations. YOYO MODE n. State in which the system is said to be when it rapidly alternates several times between being up and being down. YU-SHIANG WHOLE FISH n. The character gamma (extended SAIL ASCII 11), which with a loop in its tail looks like a fish. Usage: used primarily by people on the MIT LISP Machine. Tends to elicit incredulity from people who hear about it second-hand. ZERO v. 1. To set to zero. Usually said of small pieces of data, such as bits or words. 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. ---
