Change. A te
Chnique invented by the blue-green algae hundreds of millions of years ago to speed up their evolution, whi
Ch had been terribly slow up until then. Today, SEX parties are popular among ha
Ckers and others (of
Course, these are no longer limited to ex
Changes of geneti
C software). In general, SEX parties are a
Good Thing, but unprote
Cted SEX
Can propagate a
virus. See also
pubiC direCtory. 2. The
mnemoniC often used for Sign EXtend, a ma
Chine instru
Ction found in the
PDP-11 and many other ar
Chite
Ctures. The
RCA 1802 Chip used in the early
Elf and SuperElf
personal Computers had a "SEt X register" SEX instru
Ction, but this seems to have had little folklori
C impa
Ct. DE
C' s engineers nearly got a
PDP-11 assembler that used the "SEX" mnemoni
C out the door at one time, but (for on
Ce) marketing wasn' t asleep and for
Ced 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
Intel 8086, noted that there was originally a "SEX" instru
Ction on that pro
Cessor, too. He says that Intel management got
Cold feet and de
Creed that it be
Changed, and thus the instru
Ction was renamed "
CBW" and "
CWD" (depending on what was being extended). The
Intel 8048 (the
miCroController used in
IBM PC keyboards) is also missing straight "SEX" but has logi
Cal-or and logi
Cal-and instru
Ctions "ORL" and "ANL". The
Motorola 6809, used in the UK' s "
Dragon 32" {personal
Computer}, a
Ctually had an offi
Cial "SEX" instru
Ction the
6502 in the
Apple II with whi
Ch it
Competed did not. British ha
Ckers thought this made perfe
Ct mythi
C sense after all, it was
Commonly observed, you
Could (on some theoreti
Cal level) have sex with a dragon, but you
Can' t have sex with an apple. [
