:Eris: /e'ris/ /n./ The Greek goddess of Chaos, Discord, Confusion, and Things You Know Not Of; her name was latinized to Discordia and she was worshiped by that name in Rome. Not a very friendly deity in the Classical original, she was reinvented as a more benign personification of creative anarchy starting in 1959 by the adherents of {Discordianism} and has since been a semi-serious subject of veneration in several `fringe' cultures, including hackerdom. See {Discordianism}, {Church of the SubGenius}.
:erotics: /ee-ro'tiks/ /n./ [Helsinki University of
Technology, Finland] /n./ English-language university slang for
electronics. Often used by hackers in Helsinki, maybe because good
electronics excites them and makes them warm.
:error 33: [XEROX PARC] /n./ 1. Predicating one research effort
upon the success of another. 2. Allowing your own research effort
to be placed on the critical path of some other project (be it a
research effort or not).
:evil: /adj./ As used by hackers, implies that some system, program, person, or institution is sufficiently maldesigned as to be not worth the bother of dealing with. Unlike the adjectives in the {cretinous}/{losing}/{brain-damaged} series, `evil' does not imply incompetence or bad design, but rather a set of goals or design criteria fatally incompatible with the speaker's. This usage is more an esthetic and engineering judgment than a moral one in the mainstream sense. "We thought about adding a {Blue Glue} interface but decided it was too evil to deal with." "{TECO} is neat, but it can be pretty evil if you're prone to typos." Often pronounced with the first syllable lengthened, as /eeee'vil/. Compare {evil and rude}.
:evil and rude: /adj./ Both {evil} and {rude}, but with the additional connotation that the rudeness was due to malice rather than incompetence. Thus, for example: Microsoft's Windows NT is evil because it's a competent implementation of a bad design; it's rude because it's gratuitously incompatible with Unix in places where compatibility would have been as easy and effective to do; but it's evil and rude because the incompatibilities are apparently there not to fix design bugs in Unix but rather to lock hapless customers and developers into the Microsoft way. Hackish evil and rude is close to the mainstream sense of `evil'.
:exa-: /ek's*/ /pref./ [SI] See {{quantifiers}}.
:examining the entrails: /n./ The process of {grovel}ling through a {core dump} or hex image in an attempt to discover the bug that brought a program or system down. The reference is to divination from the entrails of a sacrified animal. Compare {runes}, {incantation}, {black art}, {desk check}.
:EXCH: /eks'ch*/ or /eksch/ /vt./ To exchange two things, each for the other; to swap places. If you point to two people sitting down and say "Exch!", you are asking them to trade places. EXCH, meaning EXCHange, was originally the name of a PDP-10 instruction that exchanged the contents of a register and a memory location. Many newer hackers are probably thinking instead of the {{PostScript}} exchange operator (which is usually written in lowercase).
:excl: /eks'kl/ /n./ Abbreviation for `exclamation point'. See {bang}, {shriek}, {{ASCII}}.
:EXE: /eks'ee/ or /eek'see/ or /E-X-E/ /n./ An executable binary file. Some operating systems (notably MS-DOS, VMS, and TWENEX) use the extension .EXE to mark such files. This usage is also occasionally found among Unix programmers even though Unix executables don't have any required suffix.
