Hidden Fibonacci computation found inside /usr/bin/top
Original: A parasitic Fibonacci computation inside /usr/bin/top
A researcher at seriot.ch has documented how a terminfo configuration can force /usr/bin/top, the standard Unix process monitor, to carry out a parasitic Fibonacci computation as a hidden side effect. The write-up explains the mechanism and its performance implications, and it is drawing attention from developers surprised that a routine terminal database entry can trigger unexpected CPU work inside a core system utility.
Why now: A technical write-up revealing an unexpected hidden computation in a basic Unix system tool is making the rounds among developers and systems programmers.
