glitch
/glich/ [German "glitschen" to slip, via Yiddish "glitshen", to slide or skid]
1. (Electronics) When the inputs of a circuit change, and the outputs change to
some random value for some very brief time before they settle down to the
correct value. If another circuit inspects the output at just the wrong time,
reading the random value, the results can be very wrong and very hard to debug
(a glitch is one of many causes of electronic heisenbugs).
2. A sudden interruption in electric service, sanity, continuity, or program
function. Sometimes recoverable. An interruption in electric service is
specifically called a "power glitch" (or power hit), of grave concern because it
usually crashes all the computers. See also gritch.
2. [Stanford] To scroll a display screen, especially several lines at a time.
WAITS terminals used to do this in order to avoid continuous scrolling, which is
distracting to the eye.
4. Obsolete. Same as magic cookie.
