[acronym, by analogy with FIFO (First In, First Out)] `First In, Still Here'. A joking way of pointing out that processing of a particular sequence of events or requests has stopped dead. Also FISH mode and FISHnet; the latter may be applied to any network that is running really slowly or exhibiting extreme flakiness.
[acronym, `Automated Retroactive Minimal Moderation'] A Usenet, cancelbot created by Dick Depew of Munroe Falls, Ohio. ARMM was intended to automatically cancel posts from anonymous-posting sites. Unfortunately, the robot's recognizer for anonymous postings triggered on its own automatically-generated control messages! Transformed by this stroke of programming ineptitude into a monster of Frankensteinian proportions, it broke loose on the night of March 30, 1993 and proceeded to spam news.admin.policy with a recursive explosion of over 200 messages. ARMM's bug produced a recursive {cascade} of messages each of which mechanically added text to the ID and Subject and some other headers of its parent. This produced a flood of messages in which each header took up several screens and each message ID and subject line got longer and longer and longer. Reactions varied from amusement to outrage. The pathological messages crashed at least one mail system, and upset people paying line charges for their Usenet feeds. One poster described the ARMM debacle as "instant Usenet history" (also establishing the term {despew}), and it has since been widely cited as a cautionary example of the havoc the combination of good intentions and incompetence can wreak on a network. The Usenet thread on the subject is archived here. Compare Great Worm; sorcerer's apprentice mode.
[acronym, from Robert Heinlein's classic SF novel The Moon is a Harsh Mistress.] "There Ain't No Such Thing As A Free Lunch", often invoked when someone is balking at the prospect of using an unpleasantly {heavyweight} technique, or at the poor quality of some piece of software, or at the {signal-to-noise ratio} of unmoderated Usenet newsgroups. "What? Don't tell me I have to implement a database back end to get my address book program to work!" "Well, TANSTAAFL you know." This phrase owes some of its popularity to the high concentration of science-fiction fans and political libertarians in hackerdom (see Appendix B for discussion).
Outside hacker circles the variant TINSTAAFL ("There is No Such Thing...") is apparently more common, and can be traced back to 1952 in the writings of ethicist Alvin Hansen. TANSTAAFL may well have arisen from it by mutation.
[Yet Another] In hackish acronyms this almost invariably expands to {Yet Another}, following the precedent set by Unix yacc(1) (Yet Another Compiler-Compiler). See {YABA}.
