The Fastest Things On Earth

Nothing breaks the sound barrier quite like a developer's fingers after accidentally deleting three hours of work. Cheetahs run at 70 mph, planes fly at 550 mph, light travels at 186,000 miles per second... but the Ctrl+Z reflex after a code deletion mistake? That's practically teleportation. Physics professors are still trying to measure it. The speed is directly proportional to how much coffee you've had and how close you are to a deadline.
