- 25. Hacker Ethics • 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 25
- 26. Hacker Culture, Common Value • Computers can change your life for the better • rough consensus and working code • http://www.ietf.org/tao.html • It’s better to ask forgiveness than permission. • If it's a good idea, go ahead and do it. It is much easier to apologize than it is to get permission. By Grace Hopper 26

- 29. Netscape vs Google • A native web application, never sold or packaged, but delivered as a service • None of the trappings of the old software industry are present. • No scheduled software releases, just continuous improvement. • No licensing or sale, just usage. • No porting to different platforms, …, just a massively scalable collection of commodity PCs running OSS operating systems plus homegrown applications and utilities that no one outside the company ever gets to see. http://oreilly.com/web2/archive/what-is-web-20.html 29
