"People who [program] have double happiness. First of all they experience the sheer beauty of elegant mathematical patterns that surround elegant computational procedures. Then they receive a practical payoff when their theories make it possible to get other jobs done more quickly and more economically.'' - Donald Knuth
So programmers are 'double happy' people?! I would like to hear that from one of the programmers Knuth ever worked with. It shows that typical scholars like Knuth have no idea of what's going on in a profit driven enterprise.
