(field of studies: Computer Science)

Computers are man's attempt at designing a cat: it does whatever it wants, whenever it wants, and rarely ever at the right time.

From then on, when anything went wrong with a computer, we said it had bugs in it.

Asking for efficiency and adaptability in the same program is like asking for a beautiful and modest wife. Although beauty and modesty have been known to occur in the same woman, we'll probably have to settle for one or the other. At least that's better than neither.
