|
|
n. [very common] Another widely used metasyntactic variable ; see foo for
|
|
|
|
|
etymology. Probably originally propagated through DECsystem manuals by
|
|
|
|
|
Digital Equipment Corporation ( DEC ) in 1960s and early 1970s; confirmed
|
|
|
|
|
sightings there go back to 1972. Hackers do not generally use this to mean
|
|
|
|
|
FUBAR in either the slang or jargon sense. See also Fred Foobar. In RFC1639,
|
|
|
|
|
FOOBAR was made an abbreviation for FTP Operation Over Big Address Records ,
|
|
|
|
|
but this was an obvious backronym. It has been plausibly suggested that
|
|
|
|
|
foobar spread among early computer engineers partly because of FUBAR and
|
|
|
|
|
partly because foo bar parses in electronics techspeak as an inverted foo
|
|
|
|
|
signal; if a digital signal is active low (so a negative or zero-voltage
|
|
|
|
|
condition represents a 1 ) then a horizontal bar is commonly placed over the
|
|
|
|
|
signal label.
