parity errors pl.n.
Little lapses of attention or (in
more severe cases) consciousness, usually brought on by having
spent all night and most of the next day hacking. "I need to go
home and crash; I'm starting to get a lot of parity errors."
Derives from a relatively common but nearly always correctable
transient error in memory hardware. It predates RAM; in fact, this
term is reported to have already have been in use in its jargon
sense back in the 1960s when magnetic cores ruled. Parity errors
can also afflict mass storage and serial communication lines; this
is more serious because not always correctable.
