18. 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 criteria
such as degrees, age, race, sex, or position
• You can create art and beauty on a computer
• Computers can change your life for the better
