buzz

vi.

1. Of a program, to run with no indication of progress and perhaps without guarantee of ever finishing; esp. said of programs thought to be executing tight loops of code. A program that is buzzing appears to be catatonic, but never gets out of catatonia, while a buzzing loop may eventually end of its own accord. “The program buzzes for about 10 seconds trying to sort all the names into order.” See spin; see also grovel.

2. [ETA Systems] To test a wire or printed circuit trace for continuity, esp. by applying an AC rather than DC signal. Some wire faults will pass DC tests but fail an AC buzz test.

3. To process an array or list in sequence, doing the same thing to each element. “This loop buzzes through the tz array looking for a terminator type.”
