Programming
(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.

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.

[This] reminds me of a quotation from somebody that, whenever he tried to explain the logical structure of a programming language to a programmer, it was like a cat trying to explain to a fish what it feels like to be wet.
