Famous quotes containing the words criteria and/or countries:
“The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
Always yield to the Hands-On Imperative!
All information should be free.
Mistrust authority—promote decentralization.
Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
You can create art and beauty on a computer.
Computers can change your life for the better.”
—Steven Levy, U.S. writer. Hackers, ch. 2, “The Hacker Ethic,” pp. 27-33, Anchor Press, Doubleday (1984)
“Yes, but I do not travel to find comfortable, rich, and hospitable people, or clear sky, or ingots that cost too much. But if there were any magnet that would point to the countries and houses where are the persons who are intrinsically rich and powerful, I would sell all, and buy it, and put myself on the road to-day.”
—Ralph Waldo Emerson (1803–1882)
