Linux for Dessert: Experimenting with the Raspberry Pi About this presentation Following the Larry Wall motto(s) – There is more than one way to do it. – Virtues of a programmer 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.
