Hack (term)
From Computer History Wiki
In a wide sense, a hack is a somewhat unexpected act of cleverness. The term originated at MIT, where it became especially associated with smart computer programmers—hackers—whose epicenter was the AI lab. Similar groups quickly appeared wherever enthusiastic people were allowed somewhat free rein with computers, and many adopted the hacking philosophy.
A display hack is a short program that produces surprisingly complex and interesting patterns on a display. In recent times, the term life hack has come to mean a smart way to make your life easier.
A hack can also be a quick and dirty solution which is somewhat unsatisfactory.
