:RTFS: /R-T-F-S/ [UNIX] 1. imp. Acronym for `Read The Fucking Source'. Stronger form of {RTFM}, used when the problem at hand is not necessarily obvious and not available from the manuals —- or the manuals are not yet written and maybe never will be. For even more tricky situations, see {RTFB}. 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 which they inevitably contain, and the stifling language 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 former Z80 hackers (almost nobody programs these things in assembler anymore). Equivalent to "Now, where was I?" or used to end a conversational digression. See {pop}; see also {POPJ}.
:RTM: /R-T-M/ [USENET: abbreviation for `Read The Manual'] 1. Politer variant of {RTFM}. 2. Robert T. Morris Jr., perpetrator of the great Internet worm of 1988 (see {Great Worm, the}); villain to many, na"ive 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 name on ITS was hacked from RTM to {RTFM}.
: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 is said to be `rude'. 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. Compare {all-elbows}.
: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. Compare {casting the runes}, {Great Runes}. 2. Special display characters (for example, the high-half graphics on an IBM PC).
: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 Syst`eme' (French; lit.
"Cowlike Bad System", idiomatically "Bitchy Bad System").
:rusty iron: n. Syn. {tired iron}. It has been claimed that this is the inevitable fate of {water MIPS}.
:rusty memory: n. Mass-storage that uses iron-oxide-based magnetic media (esp. tape and the pre-Winchester removable disk packs used in {washing machine}s). Compare {donuts}.
= S = =====
:S/N ratio: // n. (also `s/n ratio', `s:n ratio'). Syn.
{signal-to-noise ratio}. Often abbreviated `SNR'.
