Question 13

What are the three virtues of a great programmer?

Answer 13

Laziness: The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful and document what you wrote so you don’t have to answer so many questions about it.

Impatience: The anger you feel when the computer is being lazy. This makes you write programs that don’t just react to your needs, but actually anticipate them. Or at least pretend to.

Hubris: The quality that makes you write (and maintain) programs that other people won’t want to say bad things about.
