“Perl is designed to give you several ways to do anything, so consider picking the most readable one.”

“It is impossible, by the way, when picking one example of anything, to avoid picking one which is atypical in some sense.”

“Today, the problem is not to produce more so you can sell more. The fundamental question is that of the product's right to exist. And it is the designer's right and duty, in the first place, to question the legitimacy of the product, and that is how he too comes to exist. Depending on what answer he comes up with, one of the most positive things a designer can do is refuse to do anything”

“There’s only one way to succeed in anything, and that is to give it everything. I do, and I demand that my players do. ”

“I think {the designated driver program} is a great idea, because anything is safer than the way we used to do it: "Hey dude, get up! Give us a ride home, man! C'mon, whaddaya say? We'll buy ya a beer!"…The only problem with the designated driver program {is} it's not the world's most desirable job…But if you ever get talked into doing it, have fun with the group. Like at the end of the night, drop them off at the wrong damn house, preferably in their boss's front yard or something.”

“The design process involves a series of operations. In map design, it is convenient to break this sequence into three stages. In the first stage, you draw heavily on imagination and creativity. You think of various graphic possibilities, consider alternative ways…”

“When you clench your fist, no one can put anything in your hand, nor can your hand pick up anything.”

“What one person does, several people usually consider.”

“Perl itself is usually pretty good about telling you what you shouldn't do.”

“What is the shortest way to travel from Rotterdam to Groningen, in general: from given city to given city. It is the algorithm for the shortest path, which I designed in about twenty minutes. One morning I was shopping in Amsterdam with my young fiancée, and tired, we sat down on the café terrace to drink a cup of coffee and I was just thinking about whether I could do this, and I then designed the algorithm for the shortest path. As I said, it was a twenty-minute invention. In fact, it was published in ’59, three years late. The publication is still readable, it is, in fact, quite nice. One of the reasons that it is so nice was that I designed it without pencil and paper. I learned later that one of the advantages of designing without pencil and paper is that you are almost forced to avoid all avoidable complexities. Eventually that algorithm became, to my great amazement, one of the cornerstones of my fame.”
