rabbit job
n.[Cambridge] A batch job that does little, if any, real work, but creates one or more copies of itself, breeding like rabbits. Compare wabbit, fork bomb.
rain dance
n.
1. Any ceremonial action taken to correct a hardware problem, with
the expectation that nothing will be accomplished. This especially applies
to reseating printed circuit boards, reconnecting cables, etc. I
can't boot up the machine. We'll have to wait for Greg to do his rain
dance.
2. Any arcane sequence of actions performed with computers or software in order to achieve some goal; the term is usually restricted to rituals that include both an incantation or two and physical activity or motion. Compare magic, voodoo programming, black art, cargo cult programming, wave a dead chicken; see also casting the runes.
rainbow series
n.
Any of several series of technical manuals distinguished by cover
color. The original rainbow series was the NCSC security manuals (see
Orange Book).
These are now available via the web.
the term has also been commonly applied to the PostScript reference set.
Which books are meant by the
rainbow series
unqualified is thus dependent on one's local
technical culture.
random
adj.
1. Unpredictable (closest to mathematical definition); weird.
The system's been behaving pretty randomly.
2. Assorted; undistinguished. Who was at the
conference?
Just a bunch of random business
types.
3. (pejorative) Frivolous; unproductive; undirected. He's
just a random loser.
4. Incoherent or inelegant; poorly chosen; not well organized.
The program has a random set of misfeatures.
That's a
random name for that function.
Well, all the names were
chosen pretty randomly.
5. In no particular order, though deterministic. The I/O
channels are in a pool, and when a file is opened one is chosen
randomly.
6. Arbitrary. It generates a random name for the scratch
file.
7. 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 an assembler routine that could easily have been coded using only three registers, but redundantly uses seven for values with non-overlapping lifetimes, so that no one else can invoke it without first saving four extra registers. What randomness!
8. n. A random hacker; used particularly of high-school students who soak up computer time and generally get in the way.
9. n. Anyone who is not a hacker
(or, sometimes, anyone not known to the hacker speaking); the noun form of
sense 2. I went to the talk, but the audience was full of randoms
asking bogus questions
.
10. n. (occasional MIT usage) One who lives at Random Hall. See also J. Random, some random X.
11. [UK] Conversationally, a non sequitur or something similarly
out-of-the-blue. As in: Stop being so random!
This sense
equates to ‘hatstand’, taken from the Viz comic character
Roger Irrelevant - He's completely Hatstand.
Random Number God
[rec.games.roguelike.angband; often abbreviated ‘RNG’]
The malign force which lurks behind the random number generator in
Angband (and by extension elsewhere). A dark god
that demands sacrifices and toys with its victims. I just found a
really great item; I suppose the RNG is about to punish me...
Apparently, Angband's random number generator occasionally gets locked in a
repetition, so you get something with a 3% chance happening 8 times in a
row. Improbable, but far too common to be pure chance. Compare
Shub-Internet.
random numbers
n.When one wishes to specify a large but random number of things, and the context is inappropriate for N, certain numbers are preferred by hacker tradition (that is, easily recognized as placeholders). These include the following:
17 |
Long described at MIT as ‘the least random number’; see also
23. This may be Discordian in origin, or it may be related to some in-jokes
about 17 and |
23 |
Sacred number of Eris, Goddess of Discord (along with 17 and 5). |
37 |
The most random two-digit number is 37, When groups of people are polled
to pick a |
42 |
The Answer to the Ultimate Question of Life, the Universe, and
Everything ( |
69 |
From the sexual act. This one was favored in MIT's ITS culture. |
105 |
69 hex = 105 decimal, and 69 decimal = 105 octal. |
666 |
In Christian mythology, the Number of the Beast. |
For further enlightenment, study the Principia Discordia, The Hitchhiker's Guide to the Galaxy, The Joy of Sex, and the Christian Bible (Revelation 13:18). See also Discordianism or consult your pineal gland. See also for values of.
randomness
n.1. An inexplicable misfeature; gratuitous inelegance.
2. A hack or crock
that depends on a complex combination of coincidences (or, possibly, the
combination upon which the crock depends for its accidental failure to
malfunction). This hack can output characters 40--57 by putting the
character in the four-bit accumulator field of an XCT and then extracting
six bits — the low 2 bits of the XCT opcode are the right
thing.
What randomness!
3. Of people, synonymous with flakiness. The connotation is that the person
so described is behaving weirdly, incompetently, or inappropriately for
reasons which are (a) too tiresome to bother inquiring into, (b) are
probably as inscrutable as quantum phenomena anyway, and (c) are likely to
pass with time. Maybe he has a real complaint, or maybe it's just
randomness. See if he calls back.
Despite the negative connotations of most jargon uses of this term have, it is worth noting that randomness can actually be a valuable resource, very useful for applications in cryptography and elsewhere. Computers are so thoroughly deterministic that they have a hard time generating high-quality randomness, so hackers have sometimes felt the need to built special-purpose contraptions for this purpose alone. One well-known website offers random bits generated by radioactive decay. Another derives random bits from images of Lava Lite lamps. (Hackers invariably find the latter hilarious. If you have to ask why, you'll never get it.)
rape
vt.
1. To screw someone or something, violently;
in particular, to destroy a program or information irrecoverably. Often
used in describing file-system damage. So-and-so was running a
program that did absolute disk I/O and ended up raping the master
directory.
2. To strip a piece of hardware for parts.
3. [CMU/Pitt] To mass-copy files from an anonymous ftp site.
Last night I raped Simtel's dskutl directory.
rare mode
adj.
[Unix] CBREAK mode (character-by-character with interrupts enabled).
Distinguished from raw mode and
cooked mode; the phrase a sort of half-cooked (rare?)
mode
is used in the V7/BSD manuals to describe the mode. Usage:
rare.
raster blaster
n.[Cambridge] Specialized hardware for bitblt operations (a blitter). Allegedly inspired by ‘Rasta Blasta’, British slang for the sort of portable stereo Americans call a ‘boom box’ or ‘ghetto blaster’.
raster burn
n.Eyestrain brought on by too many hours of looking at low-res, poorly tuned, or glare-ridden monitors, esp. graphics monitors. See terminal illness.
rasterbation
n.[portmanteau: raster + masturbation] The gratuitous use of computer-generated images and effects in movies and graphic art which would have been better without them. Especially employed as a term of abuse by Photoshop/GIMP users and graphic artists.
rat belt
n.A cable tie, esp. the sawtoothed, self-locking plastic kind that you can remove only by cutting (as opposed to a random twist of wire or a twist tie or one of those humongous metal clip frobs). Small cable ties are mouse belts.
rat dance
n.[From the Dilbert comic strip of November 14, 1995] A hacking run that produces results which, while superficially coherent, have little or nothing to do with its original objectives. There are strong connotations that the coding process and the objectives themselves were pretty random. (In the original comic strip, the Ratbert is invited to dance on Dilbert's keyboard in order to produce bugs for him to fix, and authors a Web browser instead.) Compare Infinite-Monkey Theorem.
This term seems to have become widely recognized quite rapidly after the original strip, a fact which testifies to Dilbert's huge popularity among hackers. All too many find the perverse incentives and Kafkaesque atmosphere of Dilbert's mythical workplace reflective of their own experiences.
rathole
[from the English idiom down a rathole
for a waste of
money or time] A technical subject that is known to be able to absorb
infinite amounts of discussion time without more than an infinitesimal
probability of arrival at a conclusion or consensus. That's a
rathole
(or just Rathole!
) is considered a
pre-emptive bid to change the subject. The difference between ratholes and
religious issues is that a holy war cannot be
pre-empted in this way. Canonical examples are XML namespaces and
open-source licensing.
ratio site
[warez d00dz] An FTP site storing pirated files where one must first upload something before being able to download. There is a ratio, based on bytes or files count, between the uploads and download. For instance, on a 2:1 site, to download a 4 Mb file, one must first upload at least 2 Mb of files. The hotter the contents of the server are, the smaller the ratio is. More often than not, the server refuses uploads because its disk is full, making it useless for downloading — or the connection magically breaks after one has uploaded a large amount of files, just before the downloading phase begins. See also banner site, leech mode.
rave
vi.[WPI]
1. To persist in discussing a specific subject.
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.
6. Also used to describe a less negative form of blather, such as friendly bullshitting. ‘Rave’ differs slightly from flame in that rave implies that it is the persistence or obliviousness of the person speaking that is annoying, while flame implies somewhat more strongly that the tone or content is offensive as well.
rave on!
imp.Sarcastic invitation to continue a rave, often by someone who wishes the raver would get a clue but realizes this is unlikely.
ravs
/ravz/, also Chinese ravs n.
[primarily MIT/Boston usage] Jiao-zi (steamed or boiled) or Guo-tie
(pan-fried). A Chinese appetizer, known variously in the plural as
dumplings, pot stickers (the literal translation of guo-tie), and (around
Boston) ‘Peking Ravioli’. The term rav is short for ‘ravioli’, and
among hackers always means the Chinese kind rather than the Italian kind.
Both consist of a filling in a pasta shell, but the Chinese kind includes
no cheese, uses a thinner pasta, has a pork-vegetable filling (good ones
include Chinese chives), and is cooked differently, either by steaming or
frying. A rav or dumpling can be cooked any way, but a potsticker is
always the pan-fried kind (so called because it sticks to the frying pot
and has to be scraped off). Let's get hot-and-sour soup and three
orders of ravs.
See also oriental food.
raw mode
n.A mode that allows a program to transfer bits directly to or from an I/O device (or, under bogus operating systems that make a distinction, a disk file) without any processing, abstraction, or interpretation by the operating system. Compare rare mode, cooked mode. This is techspeak under Unix, jargon elsewhere.
RBL
/R·B·L/
Abbreviation: Realtime Blackhole List
. A service that
allows people to blacklist sites for emitting spam,
and makes the blacklist available in real time to electronic-mail transport
programs that know how to use RBL so they can filter out mail from those
sites. Drastic (and controversial) but effective. There is an RBL home page.
rc file
/R·C fi:l/ n.[Unix: from runcom files on the CTSS system 1962-63, via the startup script /etc/rc] Script file containing startup instructions for an application program (or an entire operating system), usually a text file containing commands of the sort that might have been invoked manually once the system was running but are to be executed automatically each time the system starts up. See also dot file, profile (sense 1).
read-only user
n.Describes a luser who uses computers almost exclusively for reading Usenet, bulletin boards, and/or email, rather than writing code or purveying useful information. See twink, terminal junkie, lurker.
README file
n.
Hacker's-eye introduction traditionally included in the top-level
directory of a Unix source distribution, containing a pointer to more
detailed documentation, credits, miscellaneous revision history, notes,
etc. In the Mac and PC worlds, software is not usually distributed in
source form, and the README is more likely to contain user-oriented
material like last-minute documentation changes, error workarounds, and
restrictions. When asked, hackers invariably relate the README convention
to the famous scene in Lewis Carroll's Alice's Adventures In
Wonderland in which Alice confronts magic munchies labeled
Eat Me
and Drink Me
.
The file may be named README, or READ.ME, or rarely ReadMe or readme.txt or some other variant. The all-upper-case spellings, however, are universal among Unix programmers. By ancient tradition, real source files have all-lowercase names and all-uppercase is reserved for metadata, comments, and grafitti. This is functional; because 'A' sorts before 'a' in ASCII, the README will appear in directory listings before any source file.
real estate
n.May be used for any critical resource measured in units of area. Most frequently used of chip real estate, the area available for logic on the surface of an integrated circuit (see also nanoacre). May also be used of floor space in a dinosaur pen, or even space on a crowded desktop (whether physical or electronic).
real operating system
n.
The sort the speaker is used to. People from the BSDophilic
academic community are likely to issue comments like System V? Why
don't you use a real operating system?
, people
from the commercial/industrial Unix sector are known to complain
BSD? Why don't you use a real operating
system?
, and people from IBM object Unix? Why don't you use
a real operating system?
Only
MS-DOS is universally considered unreal. See
holy wars, religious issues,
proprietary,
Get a real computer!
Real Programmer
n.
[indirectly, from the book Real Men Don't Eat
Quiche] A particular sub-variety of hacker: one possessed of a
flippant attitude toward complexity that is arrogant even when justified by
experience. The archetypal Real
Programmer likes to program on the bare metal and is very good at same, remembers the binary opcodes
for every machine he has ever programmed, thinks that HLLs are sissy, and
uses a debugger to edit his code because full-screen editors are for wimps.
Real Programmers aren't satisfied with code that hasn't been tuned into a
state of tenseness just short of rupture. Real
Programmers never use comments or write documentation: If it was
hard to write
, says the Real Programmer, it should be hard
to understand.
Real Programmers can make machines do things that
were never in their spec sheets; in fact, they are seldom really happy
unless doing so. A Real Programmer's code can awe with its fiendish
brilliance, even as its crockishness appalls. Real Programmers live on
junk food and coffee, hang line-printer art on their walls, and terrify the
crap out of other programmers — because someday, somebody else might
have to try to understand their code in order to change it. Their
successors generally consider it a Good Thing that
there aren't many Real Programmers around any more. For a famous (and
somewhat more positive) portrait of a Real Programmer, see The Story of Mel' in Appendix A. The term
itself was popularized by a letter to the editor in the July 1983
Datamation titled Real Programmers Don't Use Pascal
by Ed Post, still circulating on Usenet and Internet in on-line
form.
Typing Real Programmers Don't Use Pascal into a web search engine should turn up a copy.
Real Soon Now
adv.[orig. from SF's fanzine community, popularized by Jerry Pournelle's column in BYTE]
1. Supposed to be available (or fixed, or cheap, or whatever) real soon now according to somebody, but the speaker is quite skeptical.
2. When one's gods, fates, or other time commitments permit one to get to it (in other words, don't hold your breath). Often abbreviated RSN. Compare copious free time.
real time
1. [techspeak] adj. Describes an application which requires a program to respond to stimuli within some small upper limit of response time (typically milli- or microseconds). Process control at a chemical plant is the canonical example. Such applications often require special operating systems (because everything else must take a back seat to response time) and speed-tuned hardware.
2. adv. In jargon, refers to
doing something while people are watching or waiting. I asked her
how to find the calling procedure's program counter on the stack and she
came up with an algorithm in real time.
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
(a research project, a course, etc.) other than pure exploration. See
user. Hackers who are also students may also be
real users. I need this fixed so I can do a problem set. I'm not
complaining out of randomness, but as a real user.
See also
luser.
Real World
n.1. Those institutions at which ‘programming’ may be used in the same sentence as ‘FORTRAN’, ‘COBOL’, ‘RPG’, ‘IBM’, ‘DBASE’, etc. Places where programs do such commercially necessary but intellectually uninspiring things as generating payroll checks and invoices.
2. The location of non-programmers and activities not related to programming.
3. A bizarre dimension in which the standard dress is shirt and tie and in which a person's working hours are defined as 9 to 5 (see code grinder).
4. 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 speaking of a deceased person. It is also
noteworthy that on the campus of Cambridge University in England, there is
a gaily-painted lamp-post which bears the label ‘REALITY
CHECKPOINT’. It marks the boundary between university and the Real
World; check your notions of reality before passing. This joke is funnier
because the Cambridge ‘campus’ is actually coextensive with the
center of Cambridge town. See also fear and loathing, mundane, and
uninteresting.
()
reality check
n.1. The simplest kind of test of software or hardware; doing the equivalent of asking it what 2 + 2 is and seeing if you get 4. The software equivalent of a smoke test.
2. The act of letting a real user try out prototype software. Compare sanity check.
reality-distortion field
n.An expression used to describe the persuasive ability of managers like Steve Jobs (the term originated at Apple in the 1980s to describe his peculiar charisma). Those close to these managers become passionately committed to possibly insane projects, without regard to the practicality of their implementation or competitive forces in the marketplace.
recompile the world
The surprisingly large amount of work that needs to be done as the
result of any small but globally visible program change. The
world
may mean the entirety of some huge program, or may in theory
refer to every program of a certain class in the entire known universe. For
instance, Add one #define to stdio.h, and you have to recompile the
world.
This means that any minor change to the standard-I/O header
file theoretically mandates recompiling every C program in existence, even
if only to verify that the change didn't screw something else up. In
practice, you may not actually have to recompile the world, but the
implication is that some human cleverness is required to figure out what
parts can be safely left out.
recursive acronym
n.
A hackish (and especially MIT) tradition is to choose
acronyms/abbreviations that refer humorously to themselves or to other
acronyms/abbreviations. The original of the breed may have been TINT
(TINT Is Not TECO
). The classic examples were two MIT
editors called EINE (EINE Is Not EMACS
) and ZWEI
(ZWEI Was EINE Initially
). More recently, there is a Scheme
compiler called LIAR (Liar Imitates Apply Recursively), and
GNU (q.v., sense 1) stands for GNU's Not
Unix!
— and a company with the name Cygnus, which expands to
Cygnus, Your GNU Support
(though Cygnus people say this is a
backronym). See also mung,
EMACS.
red wire
n.[IBM] Patch wires installed by programmers who have no business mucking with the hardware. It is said that the only thing more dangerous than a hardware guy with a code patch is a softy with a soldering iron.... Compare blue wire, yellow wire, purple wire.
regexp
/reg´eksp/ n.[Unix] (alt.: regex or reg-ex)
1. Common written and spoken abbreviation for regular expression, one of the wildcard
patterns used, e.g., by Unix utilities such as
grep1,
sed1,
and
awk1.
These use conventions similar to but more elaborate than those described
under glob. For purposes of this lexicon, it is
sufficient to note that regexps also allow complemented character sets
using ^; thus, one can specify ‘any non-alphabetic
character’ with [^A-Za-z]
.
2. Name of a well-known PD regexp-handling package in portable C, written by revered Usenetter Henry Spencer.
register dancing
n.Many older processor architectures suffer from a serious shortage of general-purpose registers. This is especially a problem for compiler-writers, because their generated code needs places to store temporaries for things like intermediate values in expression evaluation. Some designs with this problem, like the Intel 80x86, do have a handful of special-purpose registers that can be pressed into service, providing suitable care is taken to avoid unpleasant side effects on the state of the processor: while the special-purpose register is being used to hold an intermediate value, a delicate minuet is required in which the previous value of the register is saved and then restored just before the official function (and value) of the special-purpose register is again needed.
rehi
[IRC, MUD] Hello again.
Very commonly used to greet
people upon returning to an IRC channel after
channel hopping.
reinvent the wheel
v.To design or implement a tool equivalent to an existing one or part of one, with the implication that doing so is silly or a waste of time. This is often a valid criticism. On the other hand, automobiles don't use wooden rollers, and some kinds of wheel have to be reinvented many times before you get them right. On the third hand, people reinventing the wheel do tend to come up with the moral equivalent of a trapezoid with an offset axle.
religion of CHI
/ki:/ n.
[Case Western Reserve University] Yet another hackish parody
religion (see also Church of the SubGenius,
Discordianism). In the mid-70s, the canonical
Introduction to Programming
courses at CWRU were taught in
Algol, and student exercises were punched on cards and run on a Univac 1108
system using a homebrew operating system named CHI. The religion had no
doctrines and but one ritual: whenever the worshiper noted that a digital
clock read 11:08, he or she would recite the phrase It is 11:08;
ABS, ALPHABETIC, ARCSIN, ARCCOS, ARCTAN.
The last five words were
the first five functions in the appropriate chapter of the Algol manual;
note the special pronunciations /obz/ and /ark´sin/ rather than the more common
/ahbz/ and /ark´si:n/. Using an alarm clock to warn
of 11:08's arrival was considered harmful.
religious issues
n.
Questions which seemingly cannot be raised without touching off
holy wars, such as What is the best operating
system (or editor, language, architecture, shell, mail reader, news
reader)?
, What about that Heinlein guy, eh?
,
What should we add to the new Jargon File?
See
holy wars; see also theology,
bigot, and compare
rathole.
This term is a prime example of ha ha only serious. People actually develop the most amazing and religiously intense attachments to their tools, even when the tools are intangible. The most constructive thing one can do when one stumbles into the crossfire is mumble Get a life! and leave — unless, of course, one's own unassailably rational and obviously correct choices are being slammed.
replicator
n.Any construct that acts to produce copies of itself; this could be a living organism, an idea (see meme), a program (see quine, worm, wabbit, fork bomb, and virus), a pattern in a cellular automaton (see life, sense 1), or (speculatively) a robot or nanobot. It is even claimed by some that Unix and C are the symbiotic halves of an extremely successful replicator; see Unix conspiracy.
restriction
n.A bug or design error that limits a program's capabilities, and which is sufficiently egregious that nobody can quite work up enough nerve to describe it as a feature. Often used (esp. by marketroid types) to make it sound as though some crippling bogosity had been intended by the designers all along, or was forced upon them by arcane technical constraints of a nature no mere user could possibly comprehend (these claims are almost invariably false).
Old-time hacker Joseph M. Newcomer advises that whenever choosing a quantifiable but arbitrary restriction, you should make it either a power of 2 or a power of 2 minus 1. If you impose a limit of 107 items in a list, everyone will know it is a random number — on the other hand, a limit of 15 or 16 suggests some deep reason (involving 0- or 1-based indexing in binary) and you will get less flamage for it. Limits which are round numbers in base 10 are always especially suspect.
retcon
/ret´kon/[short for ‘retroactive continuity’, from the Usenet newsgroup rec.arts.comics]
1. n. The common situation in pulp fiction (esp. comics or soap operas) where a new story ‘reveals’ things about events in previous stories, usually leaving the ‘facts’ the same (thus preserving continuity) while completely changing their interpretation. For example, revealing that a whole season of Dallas was a dream was a retcon.
2. vt. To write such a story
about a character or fictitious object. Byrne has retconned
Superman's cape so that it is no longer unbreakable.
Marvelman's old adventures were retconned into synthetic
dreams.
Swamp Thing was retconned from a transformed person
into a sentient vegetable.
[This term is included because it is a good example of hackish linguistic innovation in a field completely unrelated to computers. The word retcon will probably spread through comics fandom and lose its association with hackerdom within a couple of years; for the record, it started here. —ESR]
[1993 update: some comics fans on the net now claim that retcon was independently in use in comics fandom before rec.arts.comics, and have citations from around 1981. In lexicography, nothing is ever simple. —ESR]
retrocomputing
/ret'·roh·k@m·pyoo´ting/ n.Refers to emulations of way-behind-the-state-of-the-art hardware or software, or implementations of never-was-state-of-the-art; esp. if such implementations are elaborate practical jokes and/or parodies, written mostly for hack value, of more ‘serious’ designs. Perhaps the most widely distributed retrocomputing utility was the pnch6 or bcd6 program on V7 and other early Unix versions, which would accept up to 80 characters of text argument and display the corresponding pattern in punched card code. Other well-known retrocomputing hacks have included the programming language INTERCAL, a JCL-emulating shell for Unix, the card-punch-emulating editor named 029, and various elaborate PDP-11 hardware emulators and RT-11 OS emulators written just to keep an old, sourceless Zork binary running.
A tasty selection of retrocomputing programs are made available at the Retrocomputing Museum, http://www.catb.org/retro/.
return from the dead
v.To regain access to the net after a long absence. Compare person of no account.
RFC
/R·F·C/ n.[Request For Comment] One of a long-established series of numbered Internet informational documents and standards widely followed by commercial software and freeware in the Internet and Unix communities. Perhaps the single most influential one has been RFC-822 (the Internet mail-format standard). The RFCs are unusual in that they are floated by technical experts acting on their own initiative and reviewed by the Internet at large, rather than formally promulgated through an institution such as ANSI. For this reason, they remain known as RFCs even once adopted as standards.
The RFC tradition of pragmatic, experience-driven, after-the-fact
standard writing done by individuals or small working groups has important
advantages over the more formal, committee-driven process typical of ANSI
or ISO. Emblematic of some of these advantages is the existence of a
flourishing tradition of ‘joke’ RFCs; usually at least one a
year is published, usually on April 1st. Well-known joke RFCs have
included 527 (ARPAWOCKY
, R. Merryman, UCSD; 22 June 1973),
748 (Telnet Randomly-Lose Option
, Mark R. Crispin; 1 April
1978), and 1149 (A Standard for the Transmission of IP Datagrams on
Avian Carriers
, D. Waitzman, BBN STC; 1 April 1990). The first was
a Lewis Carroll pastiche; the second a parody of the TCP-IP documentation
style, and the third a deadpan skewering of standards-document legalese,
describing protocols for transmitting Internet data packets by carrier
pigeon (since actually implemented; see Appendix A). See also
Infinite-Monkey Theorem.
The RFCs are most remarkable for how well they work — they frequently manage to have neither the ambiguities that are usually rife in informal specifications, nor the committee-perpetrated misfeatures that often haunt formal standards, and they define a network that has grown to truly worldwide proportions.
RFE
/R·F·E/ n.1. [techspeak] Request For Enhancement (compare RFC).
2. [from ‘Radio Free Europe’, Bellcore and Sun] Radio Free Ethernet, a system (originated by Peter Langston) for broadcasting audio among Sun SPARCstations over the ethernet.
Right Thing
n.
That which is compellingly the correct or
appropriate thing to use, do, say, etc. Often capitalized, always
emphasized in speech as though capitalized. Use of this term often implies
that in fact reasonable people may disagree. What's the right thing
for LISP to do when it sees
mod a
0? Should it return
Oppose
Wrong Thing.a
, or give a divide-by-0 error?
rip
v.
1. To extract the digital representation of a piece of music from an
audio CD. Software that does this is often called a CD
ripper
.
2. [Amiga hackers] To extract sound or graphics from a program that they have been compiled/assembled into, or which generates them at run-time. In the case of older Amiga games this entails searching through memory shortly after a reboot. This sense has been in use for many years and probably gave rise to the (now more common) sense 1.
RL
n.
[MUD community] Real Life. Firiss laughs in RL
means
that Firiss's player is laughing. Compare
meatspace; oppose VR.
roach
vt.[Bell Labs] To destroy, esp. of a data structure. Hardware gets toasted or fried, software gets roached. Probably derived from '70s and '80s drug slang; marijuana smokers used ‘roach’ to refer to the unsmokable remnant of a joint, and to ‘roach’ a joint was therefore to destroy it.
robocanceller
/roh·boh·kan´sel·@r/A program that monitors Usenet feeds, attempting to detect and eliminate spam by sending appropriate cancel messages. Robocancellers may use the Breidbart Index as a trigger. Programming them is not a game for amateurs; see ARMM. See also Dave the Resurrector.
robust
adj.Said of a system that has demonstrated an ability to recover gracefully from the whole range of exceptional inputs and situations in a given environment. One step below bulletproof. Carries the additional connotation of elegance in addition to just careful attention to detail. Compare smart, oppose brittle.
rococo
adj.
Terminally baroque. Used to imply that a
program has become so encrusted with the software equivalent of gold leaf
and curlicues that they have completely swamped the underlying design.
Called after the later and more extreme forms of Baroque architecture and
decoration prevalent during the mid-1700s in Europe. Alan Perlis said:
Every program eventually becomes rococo, and then rubble.
Compare critical mass.
rogue
1. [Unix] n. A Dungeons-and-Dragons-like game using character graphics, written under BSD Unix and subsequently ported to other Unix systems. The original BSD curses3 screen-handling package was hacked together by Ken Arnold primarily to support games, and the development of rogue6 popularized its use; it has since become one of Unix's most important and heavily used application libraries. Nethack, Omega, Larn, Angband, and an entire subgenre of computer dungeon games (all known as ‘roguelikes’) all took off from the inspiration provided by rogue6; the popular Windows game Diablo, though graphics-intensive, has very similar play logic. See also nethack, moria, Angband.
2. [Usenet] adj. An
ISP which permits net abuse (usually in the form of
spamming) by its customers, or which itself engages
in such activities. Rogue ISPs are sometimes subject to
IDPs or UDPs. Sometimes
deliberately misspelled as rouge
.
room-temperature IQ
quant.
[IBM] 80 or below (nominal room temperature is 72 degrees
Fahrenheit, 22 degrees Celsius). Used in describing the expected
intelligence range of the luser. Well, but
how's this interface going to play with the room-temperature IQ
crowd?
See drool-proof paper. This is a
much more insulting phrase in countries that use Celsius
thermometers.
root
n.1. [Unix] The superuser account (with user name ‘root’) that ignores permission bits, user number 0 on a Unix system. The term avatar is also used.
2. The top node of the system directory structure; historically the home directory of the root user, but probably named after the root of an (inverted) tree.
3. By extension, the privileged system-maintenance login on any OS. See root mode, go root, see also wheel.
root mode
n.Syn. with wizard mode or wheel mode. Like these, it is often generalized to describe privileged states in systems other than OSes.
rootkit
/root´kit/ n.[very common] A kit for getting root; an automated cracking tool. What script kiddies use. The existence of rootkits means that large-scale attacks on insecure computers can be done by people with no technical skills other than the ability to follow directions. Rootkits designed to crack Microsoft operating systems and webservers are especially common, because their software is so porous and easy to crack.
rot13
/rot ther´teen/ n.,v.
[Usenet: from ‘rotate alphabet 13 places’] The simple
Caesar-cypher encryption that replaces each English letter with the one 13
places forward or back along the alphabet, so that The butler did
it!
becomes Gur ohgyre qvq vg!
Most Usenet news
reading and posting programs include a rot13 feature. It is used to
enclose the text in a sealed wrapper that the reader must choose to open
— e.g., for posting things that might offend some readers, or
spoilers. A major advantage of rot13 over
rot(N) for other N is that it is
self-inverse, so the same code can be used for encoding and decoding. See
also spoiler space, which has partly displaced rot13
since non-Unix-based newsreaders became common.
rotary debugger
n.[Commodore] Essential equipment for those late-night or early-morning debugging sessions. Mainly used as sustenance for the hacker. Comes in many decorator colors, such as Sausage, Pepperoni, and Garbage. See ANSI standard pizza.
RTBM
/R·T·B·M/ imp.
[Unix] Commonwealth Hackish variant of RTFM;
expands to ‘Read The Bloody Manual’. RTBM is often the entire
text of the first reply to a question from a newbie;
the second would escalate to
RTFM
.
RTFAQ
/R·T·F·A·Q/ imp.[Usenet: primarily written, by analogy with RTFM] Abbrev. for ‘Read the FAQ!’, an exhortation that the person addressed ought to read the newsgroup's FAQ list before posting questions.
RTFB
/R·T·F·B/ imp.
[Unix] Abbreviation for ‘Read The Fucking Binary’. Used
when neither documentation nor source for the problem at hand exists, and
the only thing to do is use some debugger or monitor and directly analyze
the assembler or even the machine code. No source for the buggy
port driver? Aaargh! I hate proprietary operating
systems. Time to RTFB.
Of the various RTF? forms, ‘RTFB’ is the least pejorative against anyone asking a question for which RTFB is the answer; the anger here is directed at the absence of both source and adequate documentation.
RTFM
/R·T·F·M/ imp.[Unix] Abbreviation for ‘Read The Fucking Manual’.
1. Used by gurus to brush off questions they consider trivial or annoying. Compare Don't do that then!.
2. Used when reporting a problem to indicate that you aren't just
asking out of randomness. No, I can't figure
out how to interface Unix to my toaster, and yes, I have RTFM.
Unlike sense 1, this use is considered polite. See also
FM, RTFAQ,
RTFB, RTFS,
STFW, RTM, all of which
mutated from RTFM, and compare UTSL.
RTFS
/R·T·F·S/[Unix]
1. imp. Abbreviation for ‘Read The Fucking Source’. Variant form of RTFM, used when the problem at hand is not necessarily obvious and not answerable from the manuals — or the manuals are not yet written and maybe never will be. For even trickier situations, see RTFB. Unlike RTFM, the anger inherent in RTFS is not usually directed at the person asking the question, but rather at the people who failed to provide adequate documentation.
2. imp. ‘Read The Fucking Standard’; this oath can only be used when the problem area (e.g., a language or operating system interface) has actually been codified in a ratified standards document. The existence of these standards documents (and the technically inappropriate but politically mandated compromises that they inevitably contain, and the impenetrable legalese in which they are invariably written, and the unbelievably tedious bureaucratic process by which they are produced) can be unnerving to hackers, who are used to a certain amount of ambiguity in the specifications of the systems they use. (Hackers feel that such ambiguities are acceptable as long as the Right Thing to do is obvious to any thinking observer; sadly, this casual attitude towards specifications becomes unworkable when a system becomes popular in the Real World.) Since a hacker is likely to feel that a standards document is both unnecessary and technically deficient, the deprecation inherent in this term may be directed as much against the standard as against the person who ought to read it.
RTI
/R·T·I/ interj.
The mnemonic for the ‘return from interrupt’ instruction
on many computers including the 6502 and 6800. The variant RETI is found among Z80 hackers. Equivalent to
Now, where was I?
or used to end a conversational
digression. See pop.
RTM
/R·T·M/1. [Usenet: abbreviation for ‘Read The Manual’] Politer variant of RTFM.
2. Robert Tappan Morris, perpetrator of the great Internet worm of 1988 (see Great Worm); villain to many, naive hacker gone wrong to a few. Morris claimed that the worm that brought the Internet to its knees was a benign experiment that got out of control as the result of a coding error. After the storm of negative publicity that followed this blunder, Morris's username on ITS was hacked from RTM to RTFM.
RTS
/R·T·S/ imp.Abbreviation for ‘Read The Screen’. Mainly used by hackers in the microcomputer world. Refers to what one would like to tell the suit one is forced to explain an extremely simple application to. Particularly appropriate when the suit failed to notice the ‘Press any key to continue’ prompt, and wishes to know ‘why won't it do anything’. Also seen as ‘RTFS’ in especially deserving cases.
rubber-hose cryptanalysis
n.
[sci.crypt newsgroup] The technique of breaking a code or cipher by
finding someone who has the key and applying a rubber hose vigorously and
repeatedly to the soles of that luckless person's feet until the key is
discovered. Shorthand for any method of coercion: the originator of the
term drily noted that it can take a surprisingly short time and is
quite computationally inexpensive
relative to other cryptanalysis
methods. Compare social engineering,
brute force.
rude
[WPI] adj.1. (of a program) Badly written.
2. Functionally poor, e.g., a program that is very difficult to use because of gratuitously poor (random?) design decisions. Oppose cuspy.
3. Anything that manipulates a shared resource without regard for its other users in such a way as to cause a (non-fatal) problem. Examples: programs that change tty modes without resetting them on exit, or windowing programs that keep forcing themselves to the top of the window stack.
runes
pl.n.1. Anything that requires heavy wizardry or black art to parse: core dumps, JCL commands, APL, or code in a language you haven't a clue how to read. Not quite as bad as line noise, but close. Compare casting the runes, Great Runes.
2. Special display characters (for example, the high-half graphics on an IBM PC).
3. [borderline techspeak] 16-bit characters from the Unicode multilingual character set.
runic
adj.
Syn. obscure. VMS fans sometimes refer to
Unix as ‘Runix’; Unix fans return the compliment by expanding
VMS to ‘Very Messy Syntax’ or ‘Vachement Mauvais
Système’ (French idiom, Hugely Bad
System
).
rusty wire
n.
[Amateur Packet Radio] Any very noisy network medium, in which the
packets are subject to frequent corruption. Most prevalent in reference to
wireless links subject to all the vagaries of RF noise and marginal
propagation conditions. Yes, but how good is your whizbang new
protocol on really rusty wire?
