The Jargon File

A Chronology...The Jargon FileComputer Dictionary
(spelled out, NOT pronounced "fittip") 1. n. The File Transfer Protocol for transmitting files between systems on the ARPAnet.
2. v. To transfer a file using the File Transfer Program. "Lemme get this copy of Wuthering Heights FTP'd from SAIL."
1.v. To perform in an incomplete but marginally acceptable way, particularly with respect to the writing of a program. "I didn't feel like going through that pain and suffering, so I fudged it."
2. n. The resulting code.
n. A value or parameter that is varied in an ad hoc way to produce the desired result. The terms "tolerance" and "slop" are also used, though these usually indicate a one-sided leeway, such as a buffer which is made larger than necessary because one isn't sure exactly how large it needs to be, and it is better to waste a little space than to lose completely for not having enough. A fudge factor, on the other hand, can often be tweaked in more than one direction. An example might be the coefficients of an equation, where the coefficients are varied in an attempt to make the equation fit certain criteria.
[for Dick Gabriel, SAIL volleyball fanatic] n. An unnecessary (in the opinion of the opponent) stalling tactic, e.g., tying one's shoelaces or hair repeatedly, asking the time, etc. Also used to refer to the perpetrator of such tactics. Also, "pulling a Gabriel", "Gabriel mode".
n. (Stanford) Another meta-word popular among SAIL hackers.
[as in "gas chamber"] interj. 1. A term of disgust and hatred, implying that gas should be dispensed in generous quantities, thereby exterminating the source of irritation. "Some loser just reloaded the system for no reason! Gas!"
2. A term suggesting that someone or something ought to be flushed out of mercy. "The system's wedging every few minutes. Gas!" 3. v. FLUSH (q.v.). "You should gas that old crufty software." 4. GASEOUS adj. Deserving of being gassed. Usage: primarily used by Geoff Goodfellow at SRI, but spreading.
[from LISP terminology]1.v. To clean up and throw away useless things. "I think I'll GC the top of my desk today."
2.To recycle, reclaim, or put to another use.
3. To forget. The implication is often that one has done so deliberately.
4. n. An instantiation of the GC process.
[from Einstein's term "gedanken-experimenten", such as the standard proof that E=mc2] adj. An AI project which is written up in grand detail without ever being implemented to any great extent. Usually perpetrated by people who aren't very good hackers or find programming distasteful or are just in a hurry. A gedanken thesis is usually marked by an obvious lack of intuition about what is programmable and what is not and about what does and does not constitute a clear specification of a program-related concept such as an algorithm.
