SEX

|
|
/seks/ [Sun Users' Group elsewhere] n. 1. Software EXchange. A technique
|
|
invented by the blue-green algae hundreds of millions of years ago to speed
|
|
up their evolution, which had been terribly slow up until then. Today, SEX
|
|
parties are popular among hackers and others (of course, these are no longer
|
|
limited to exchanges of genetic software). In general, SEX parties are a
|
|
Good Thing , but unprotected SEX can propagate a virus. See also pubic
|
|
directory. 2. The rather Freudian mnemonic often used for Sign EXtend, a
|
|
machine instruction found in the PDP-11 and many other architectures. The
|
|
RCA 1802 chip used in the early Elf and SuperElf personal computers had a
|
|
SEt X register SEX instruction, but this seems to have had little folkloric
|
|
impact. The Data General instruction set also had SEX. DEC 's engineers
|
|
nearly got a PDP-11 assembler that used the SEX mnemonic out the door at one
|
|
time, but (for once) marketing wasn't asleep and forced a change. That
|
|
wasn't the last time this happened, either. The author of The Intel 8086
|
|
Primer , who was one of the original designers of the 8086, noted that there
|
|
was originally a SEX instruction on that processor, too. He says that Intel
|
|
management got cold feet and decreed that it be changed, and thus the
|
|
instruction was renamed CBW and CWD (depending on what was being extended).
|
|
Amusingly, the Intel 8048 (the microcontroller used in IBM PC keyboards) is
|
|
also missing straight SEX but has logical-or and logical-and instructions
|
|
ORL and ANL. The Motorola 6809, used in the Radio Shack Color Computer and
|
|
in U.K.'s Dragon 32 personal computer, actually had an official SEX
|
|
instruction; the 6502 in the Apple II with which it competed did not.
|
|
British hackers thought this made perfect mythic sense; after all, it was
|
|
commonly observed, you could (on some theoretical level) have sex with a
|
|
dragon, but you can't have sex with an apple.
