Ethnic. Spicy. Oriental, esp. Chinese and most esp. Szechuan, Hunan, and Mandarin (hackers consider Cantonese vaguelydéclassé). Hackers prefer the exotic; for example, the Japanese-food fans among them will eat with gusto such delicacies as fugu (poisonous pufferfish) and whale. Thai food has experienced flurries of popularity. Where available, high-quality Jewish delicatessen food is much esteemed. A visible minority of Southwestern and Pacific Coast hackers prefers Mexican.
For those all-night hacks, pizza and microwaved burritos are big. Interestingly, though the mainstream culture has tended to think of hackers as incorrigible junk-food junkies, many have at least mildly health-foodist attitudes and are fairly discriminating about what they eat. This may be generational; anecdotal evidence suggests that the stereotype was more on the mark before the early 1980s.

Vaguely liberal-moderate, except for the strong libertarian contingent which rejects conventional left-right politics entirely. The only safe generalization is that hackers tend to be rather anti-authoritarian; thus, both conventional conservatism and `hard' leftism are rare. Hackers are far more likely than most non-hackers to either (a) be aggressively apolitical or (b) entertain peculiar or idiosyncratic political ideas and actually try to live by them day-to-day.

Hackerdom is still predominantly male. However, the percentage of women is clearly higher than the low-single-digit range typical for technical professions, and female hackers are generally respected and dealt with as equals.
In the U.S., hackerdom is predominantly Caucasian with strong minorities of Jews (East Coast) and Orientals (West Coast). The Jewish contingent has exerted a particularly pervasive cultural influence (seeFood, above, and note that several common jargon terms are obviously mutated Yiddish).
The ethnic distribution of hackers is understood by them to be a function of which ethnic groups tend to seek and value education. Racial and ethnic prejudice is notably uncommon and tends to be met with freezing contempt.
When asked, hackers often ascribe their culture's gender- and color-blindness to a positive effect of text-only network channels, and this is doubtless a powerful influence. Also, the ties many hackers have to AI research and SF literature may have helped them to develop an idea of personhood that is inclusive rather than exclusive -- after all, if one's imagination readily grants full human rights to future AI programs, robots, dolphins, and extraterrestrial aliens, mere color and gender can't seem very important any more.

Agnostic. Atheist. Non-observant Jewish. Neo-pagan. Very commonly, three or more of these are combined in the same person. Conventional faith-holding Christianity is rare though not unknown.
Even hackers who identify with a religious affiliation tend to be relaxed about it, hostile to organized religion in general and all forms of religious bigotry in particular. Many enjoy `parody' religions such as Discordianism and the Church of the SubGenius.
Also, many hackers are influenced to varying degrees by Zen Buddhism or (less commonly) Taoism, and blend them easily with their `native' religions.
There is a definite strain of mystical, almost Gnostic sensibility that shows up even among those hackers not actively involved with neo-paganism, Discordianism, or Zen. Hacker folklore that pays homage to `wizards' and speaks of incantations and demons has too much psychological truthfulness about it to be entirely a joke.

Most hackers don't smoke tobacco, and use alcohol in moderation if at all. However, there has been something of a trend towards exotic beers since about 1995, especially among younger Linux hackers apparently influenced by Linus Torvalds's fondness for Guiness.
Limited use of non-addictive psychedelic drugs, such as cannabis, LSD, psilocybin, nitrous oxide, etc., used to be relatively common and is still regarded with more tolerance than in the mainstream culture. Use of `downers' and opiates, on the other hand, appears to be particularly rare; hackers seem in general to dislike drugs that make them stupid. Buton the gripping hand, many hackers regularly wire up on caffeine and/or sugar for all-night hacking runs.

In the United States, hackerdom revolves on a Bay Area-to-Boston axis; about half of the hard core seems to live within a hundred miles of Cambridge (Massachusetts) or Berkeley (California), although there are significant contingents in Los Angeles, in the Pacific Northwest, and around Washington DC. Hackers tend to cluster around large cities, especially `university towns' such as the Raleigh-Durham area in North Carolina or Princeton, New Jersey (this may simply reflect the fact that many are students or ex-students living near their alma maters).

Hackerdom easily tolerates a much wider range of sexual and lifestyle variation than the mainstream culture. It includes a relatively large gay and bisexual contingent. Hackers are somewhat more likely to live in polygynous or polyandrous relationships, practice open marriage, or live in communes or group houses. In this, as in general appearance, hackerdom semi-consciously maintains `counterculture' values.

The most obvious common `personality' characteristics of hackers are high intelligence, consuming curiosity, and facility with intellectual abstractions. Also, most hackers are `neophiles', stimulated by and appreciative of novelty (especially intellectual novelty). Most are also relatively individualistic and anti-conformist.
Although high general intelligence is common among hackers, it is not thesine qua nonone might expect. Another trait is probably even more important: the ability to mentally absorb, retain, and reference large amounts of `meaningless' detail, trusting to later experience to give it context and meaning. A person of merely average analytical intelligence who has this trait can become an effective hacker, but a creative genius who lacks it will swiftly find himself outdistanced by people who routinely upload the contents of thick reference manuals into their brains. [During the production of the first book version of this document, for example, I learned most of the rather complex typesetting language TeX over about four working days, mainly by inhaling Knuth's 477-page manual. My editor's flabbergasted reaction to this genuinely surprised me, because years of associating with hackers have conditioned me to consider such performances routine and to be expected. --ESR]
Contrary to stereotype, hackers arenotusually intellectually narrow; they tend to be interested in any subject that can provide mental stimulation, and can often discourse knowledgeably and even interestingly on any number of obscure subjects -- if you can get them to talk at all, as opposed to, say, going back to their hacking.
It is noticeable (and contrary to many outsiders' expectations) that the better a hacker is at hacking, the more likely he or she is to have outside interests at which he or she is more than merely competent.
Hackers are `control freaks' in a way that has nothing to do with the usual coercive or authoritarian connotations of the term. In the same way that children delight in making model trains go forward and back by moving a switch, hackers love making complicated things like computers do nifty stuff for them. But it has to betheirnifty stuff. They don't like tedium, nondeterminism, or most of the fussy, boring, ill-defined little tasks that go with maintaining a normal existence. Accordingly, they tend to be careful and orderly in their intellectual lives and chaotic elsewhere. Their code will be beautiful, even if their desks are buried in 3 feet of crap.
Hackers are generally only very weakly motivated by conventional rewards such as social approval or money. They tend to be attracted by challenges and excited by interesting toys, and to judge the interest of work or other activities in terms of the challenges offered and the toys they get to play with.
In terms of Myers-Briggs and equivalent psychometric systems, hackerdom appears to concentrate the relatively rare INTJ and INTP types; that is, introverted, intuitive, and thinker types (as opposed to the extroverted-sensate personalities that predominate in the mainstream culture). ENT[JP] types are also concentrated among hackers but are in a minority.

Personality Characteristics

Appendix B
Hackers have relatively little ability to identify emotionally with other people. This may be because hackers generally aren't much like `other people'. Unsurprisingly, hackers also tend towards self-absorption, intellectual arrogance, and impatience with people and tasks perceived to be wasting their time.
As cynical as hackers sometimes wax about the amount of idiocy in the world, they tend by reflex to assume that everyone is as rational, `cool', and imaginative as they consider themselves. This bias often contributes to weakness in communication skills. Hackers tend to be especially poor at confrontation and negotiation.
Because of their passionate embrace of (what they consider to be) theRight Thing, hackers can be unfortunately intolerant and bigoted on technical issues, in marked contrast to their general spirit of camaraderie and tolerance of alternative viewpoints otherwise. Old-timeITSpartisans look down on the ever-growing hordes ofUnixhackers; Unix aficionados despiseVMSandMS-DOS; and hackers who are used to conventional command-line user interfaces loudly loathe mouse-and-menu based systems such as the Macintosh. Hackers who don't indulge inUsenetconsider it a huge waste of time andbandwidth; fans of old adventure games such asADVENTandZorkconsiderMUDs to be glorified chat systems devoid of atmosphere or interesting puzzles; hackers who are willing to devote endless hours to Usenet or MUDs considerIRCto be arealwaste of time; IRCies think MUDs might be okay if there weren't all those silly puzzles in the way. And, of course, there are the perennialholy wars--EMACSvs.vi,big-endianvs.little-endian, RISC vs. CISC, etc., etc., etc. As in society at large, the intensity and duration of these debates is usually inversely proportional to the number of objective, factual arguments available to buttress any position.
As a result of all the above traits, many hackers have difficulty maintaining stable relationships. At worst, they can produce the classiccomputer geek: withdrawn, relationally incompetent, sexually frustrated, and desperately unhappy when not submerged in his or her craft. Fortunately, this extreme is far less common than mainstream folklore paints it -- but almost all hackers will recognize something of themselves in the unflattering paragraphs above.
Hackers are often monumentally disorganized and sloppy about dealing with the physical world. Bills don't get paid on time, clutter piles up to incredible heights in homes and offices, and minor maintenance tasks get deferred indefinitely.
1994-95's fad behavioral disease was a syndrome called Attention Deficit Disorder (ADD), supposedly characterized by (among other things) a combination of short attention span with an ability to `hyperfocus' imaginatively on interesting tasks. In 1998-1999 another syndrome that is said to overlap with many hacker traits entered popular awareness: Asperger's syndrome (AS). This disorder is also sometimes called `high-function autism', though researchers are divided on whether AS is in fact a mild form of autism or a distinct syndrome with a different etiology. AS patients exhibit mild to severe deficits in interpreting facial and body-language cues and in modeling or empathizing with others' emotions. Though some AS patients exhibit mild retardation, others compensate for their deficits with high intelligence and analytical ability, and frequently seek out technical fields where problem-solving abilities are at a premium and people skills are relatively unimportant. Both syndromes are thought to relate to abnormalities in neurotransmitter chemistry, especially the brain's processing of serotonin.
Many hackers have noticed that mainstream culture has shown a tendency to pathologize and medicalize normal variations in personality, especially those variations that make life more complicated for authority figures and conformists. Thus, hackers aware of the issue tend to be among those questioning whether ADD and AS actually exist; and if so whether they are really `diseases' rather than extremes of a normal genetic variation like having freckles or being able to taste DPT. In either case, they have a sneaking tendency to wonder if these syndromes are over-diagnosed and over-treated. After all, people in authority will always be inconvenienced by schoolchildren or workers or citizens who are prickly, intelligent individualists - thus, any social system that depends on authority relationships will tend to helpfully ostracize and therapize and drug such `abnormal' people until they are properly docile and stupid and `well-socialized'.
So hackers tend to believe they have good reason for skepticism about clinical explanations of the hacker personality. That being said, most would also concede that some hacker traits coincide with indicators for ADD and AS - the status of caffeeine as a hacker beverage of choice may be connected to the fact that it bonds to the same neural receptors as Ritalin, the drug most commonly prescribed for ADD. It is probably true that boosters of both would find a rather higher rate of clinical ADD among hackers than the supposedly mainstream-normal 3-5% (AS is rarer and there are not yet good estimates of incidence as of 2000).

Hackers are more likely to have cats than dogs (in fact, it is widely grokked that cats have the hacker nature). Many drive incredibly decrepit heaps and forget to wash them; richer ones drive spiffy Porsches and RX-7s and then forget to have them washed. Almost all hackers have terribly bad handwriting, and often fall into the habit of block-printing everything like junior draftsmen.

If you enjoyed the Jargon File, please help the culture that created it grow and flourish. Here are several ways you can help:
• If you are a writer or journalist, don't say or writehackerwhen you meancracker. If you work with writers or journalists, educate them on this issue and push them to do the right thing. If you catch a newspaper or magazine abusing the work `hacker', write them and straighten them out (this appendix includes a model letter).
• If you're a techie or computer hobbyist, get involved with one of the free Unixes. Toss out that lame Microsoft OS, or confine it to one disk partition and put Linux or FreeBSD or NetBSD on the other one. And the next time your friend or boss is thinking about some proprietary software `solution' that costs more than it's worth, be ready to blow the competition away with open-source software running over a Unix.
• Contribute to organizations like the Free Software Foundation that promote the production of high-quality free and open-source software. You can reach the Free Software Foundation atgnu@gnu.org, by phone at +1-617-542-5942, or by snail-mail at 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA.
• Support the League for Programming Freedom, which opposes over-broad software patents that constantly threaten to blow up in hackers' faces, preventing them from developing innovative software for tomorrow's needs. You can reach the League for Programming Freedom atlpf@uunet.uu.net. by phone at +1 617 621 7084, or by snail-mail at 1 Kendall Square #143, P.O.Box 9171, Cambridge, Massachusetts 02139 USA.
• Join the continuing fight against Internet censorship, visit the Center for Democracy and Technology Home Page at http://www.cdt.org.
• If you do nothing else, please help fight government attempts to seize political control of Internet content and restrict strong cryptography. The so-called `Communications Decency Act' was declared unconstitutional by the Supreme Court, but U.S. cryptography policy still infringes our First Amendment rights. Surf to the Center for Democracy and technology's home page at http://www.cdt.org to see what you can do to help fight censorship of the net.
Here's the text of a letter RMS wrote to the Wall Street Journal to complain about their policy of using "hacker" only in a pejorative sense. We hear that most major newspapers have the same policy. If you'd like to help change this situation, send your favorite newspaper the same letter - or, better yet, write your own letter.

I am not a cracker; I don't make a practice of breaking computer security.There's nothing shameful about the hacking I do.

You are giving hackers a bad name.The saddest thing is that this problem is perpetuated deliberately. Your reporters know the difference between "hacker" and "security breaker". They know how to make the distinction, but you don't let them! You insist on using "hacker" pejoratively. When reporters try to use another word, you change it. When reporters try to explain the other meanings, you cut it.Of course, you have a reason. You say that readers have become used to your insulting usage of "hacker", so that you cannot change it now. Well, you can't undo past mistakes today; but that is no excuse to repeat them tomorrow.If I were what you call a "hacker", at this point I would threaten to crack your computer and crash it. But I am a hacker, not a cracker. I don't do that kind of thing! I have enough computers to play with at home and at work; I don't need yours. Besides, it's not my way to respond to insults with violence. My response is this letter.You owe hackers an apology; but more than that, you owe us ordinary respect.Sincerely, etc.

Here are some other books you can read to help you understand the hacker mindset.
Escher, Bach: An Eternal Golden BraidGödel, Escher, Bach: An Eternal Golden BraidDouglas HofstadterBasic Books, 1979ISBN 0-394-74502-7
This book reads like an intellectual Grand Tour of hacker preoccupations. Music, mathematical logic, programming, speculations on the nature of intelligence, biology, and Zen are woven into a brilliant tapestry themed on the concept of encoded self-reference. The perfect left-brain companion to "Illuminatus".
Illuminatus!I. "The Eye in the Pyramid"II. "The Golden Apple"III. "Leviathan".Robert Shea and Robert Anton WilsonDell, 1988ISBN 0-440-53981-1
This work of alleged fiction is an incredible berserko-surrealist rollercoaster of world-girdling conspiracies, intelligent dolphins, the fall of Atlantis, who really killed JFK, sex, drugs, rock'n'roll, and the Cosmic Giggle Factor. First published in three volumes, but there is now a one-volume trade paperback, carried by most chain bookstores under SF. The perfect right-brain companion to Hofstadter's "Gödel, Escher, Bach". SeeEris,Discordianism,random numbers,Church of the SubGenius.
The Hitchhiker's Guide to the GalaxyDouglas AdamsPocket Books, 1981ISBN 0-671-46149-4
This `Monty Python in Space' spoof of SF genre traditions has been popular among hackers ever since the original British radio show. Read it if only to learn about Vogons (seebogon) and the significance of the number 42 (seerandom numbers) -- and why the winningest chess program of 1990 was called `Deep Thought'.
The Tao of ProgrammingJames GeoffreyInfobooks, 1987ISBN 0-931137-07-1
This gentle, funny spoof of the "Tao Te Ching" contains much that is illuminating about the hacker way of thought. "When you have learned to snatch the error code from the trap frame, it will be time for you to leave."
HackersSteven LevyAnchor/Doubleday 1984ISBN 0-385-19195-2
Levy's book is at its best in describing the early MIT hackers at the Model Railroad Club and the early days of the microcomputer revolution. He never understood Unix or the networks, though, and his enshrinement of Richard Stallman as "the last true hacker" turns out (thankfully) to have been quite misleading. Despite being a bit dated and containing some minor errors (many fixed in the paperback edition), this remains a useful and stimulating book that captures the feel of several important hacker subcultures.
The Computer ContradictionaryStan Kelly-BootleMIT Press, 1995ISBN 0-262-61112-0
This pastiche of Ambrose Bierce's famous work is similar in format to the Jargon File (and quotes several entries from TNHD-2) but somewhat different in tone and intent. It is more satirical and less anthropological, and is largely a product of the author's literate and quirky imagination. For example, it defines `computer science' as "a study akin to numerology and astrology, but lacking the precision of the former and the success of the latter" and `implementation' as "The fruitless struggle by the talented and underpaid to fulfill promises made by the rich and ignorant"; `flowchart' becomes "to obfuscate a problem with esoteric cartoons". Revised and expanded from "The Devil's DP Dictionary", McGraw-Hill 1981, ISBN 0-07-034022-6; that work had some stylistic influence on TNHD-1.
The Devouring Fungus: Tales from the Computer AgeKarla JenningsNorton, 1990ISBN 0-393-30732-8
The author of this pioneering compendium knits together a great deal of computer- and hacker-related folklore with good writing and a few well-chosen cartoons. She has a keen eye for the human aspects of the lore and is very good at illuminating the psychology and evolution of hackerdom. Unfortunately, a number of small errors and awkwardnesses suggest that she didn't have the final manuscript checked over by a native speaker; the glossary in the back is particularly embarrassing, and at least one classic tale (the Magic Switch story, retold here underA Story About Magicin Appendix A is given in incomplete and badly mangled form. Nevertheless, this book is a win overall and can be enjoyed by hacker and non-hacker alike.
The Soul of a New MachineTracy KidderLittle, Brown, 1981(paperback: Avon, 1982ISBN 0-380-59931-7)
This book (a 1982 Pulitzer Prize winner) documents the adventure of the design of a new Data General computer, the MV-8000 Eagle. It is an amazingly well-done portrait of the hacker mindset -- although largely the hardware hacker -- done by a complete outsider. It is a bit thin in spots, but with enough technical information to be entertaining to the serious hacker while providing non-technical people a view of what day-to-day life can be like -- the fun, the excitement, the disasters. During one period, when the microcode and logic were glitching at the nanosecond level, one of the overworked engineers departed the company, leaving behind a note on his terminal as his letter of resignation: "I am going to a commune in Vermont and will deal with no unit of time shorter than a season."
Life with UNIX: a Guide for EveryoneDon Libes and Sandy ResslerPrentice-Hall, 1989ISBN 0-13-536657-7
The authors of this book set out to tell you all the things about Unix that tutorials and technical books won't. The result is gossipy, funny, opinionated, downright weird in spots, and invaluable. Along the way they expose you to enough of Unix's history, folklore and humor to qualify as a first-class source for these things. Because so much of today's hackerdom is involved with Unix, this in turn illuminates many of its in-jokes and preoccupations.
True Names...and Other DangersVernor VingeBaen Books, 1987ISBN 0-671-65363-6
Hacker demigod Richard Stallman used to say that the title story of this book "expresses the spirit of hacking best". Until the subject of the next entry came out, it was hard to even nominate another contender. The other stories in this collection are also fine work by an author who has since won multiple Hugos and is one of today's very best practitioners of hard SF.
Snow CrashNeal StephensonBantam, 1992ISBN 0-553-56261-4
Stephenson's epic, comic cyberpunk novel is deeply knowing about the hacker psychology and its foibles in a way no other author of fiction has ever even approached. His imagination, his grasp of the relevant technical details, and his ability to communicate the excitement of hacking and its results are astonishing, delightful, and (so far) unsurpassed.
Cyberpunk: Outlaws and Hackers on the Computer FrontierKatie Hafner & John MarkoffSimon & Schuster 1991ISBN 0-671-68322-5
This book gathers narratives about the careers of three notorious crackers into a clear-eyed but sympathetic portrait of hackerdom's dark side. The principals are Kevin Mitnick, "Pengo" and "Hagbard" of the Chaos Computer Club, and Robert T. Morris (seeRTM, sense 2) . Markoff and Hafner focus as much on their psychologies and motivations as on the details of their exploits, but don't slight the latter. The result is a balanced and fascinating account, particularly useful when read immediately before or after Cliff Stoll'sThe Cuckoo's Egg. It is especially instructive to compare RTM, a true hacker who blundered, with the sociopathic phone-freak Mitnick and the alienated, drug-addled crackers who made the Chaos Club notorious. The gulf betweenwizardandwannabeehas seldom been made more obvious.
TechnobabbleJohn BarryMIT Press 1991ISBN 0-262-02333-4
Barry's book takes a critical and humorous look at the `technobabble' of acronyms, neologisms, hyperbole, and metaphor spawned by the computer industry. Though he discusses some of the same mechanisms of jargon formation that occur in hackish, most of what he chronicles is actually suit-speak -- the obfuscatory language of press releases, marketroids, and Silicon Valley CEOs rather than the playful jargon of hackers (most of whom wouldn't be caught dead uttering the kind of pompous, passive-voiced word salad he deplores).
The Cuckoo's EggClifford StollDoubleday 1989ISBN 0-385-24946-2
Clifford Stoll's absorbing tale of how he tracked Markus Hess and the Chaos Club cracking ring nicely illustrates the difference between `hacker' and `cracker'. Stoll's portrait of himself, his lady Martha, and his friends at Berkeley and on the Internet paints a marvelously vivid picture of how hackers and the people around them like to live and how they think.
