"Before the word "hacker" was misappropriated to describe people who break into computer systems, the term was coined (in the early 1960s) to describe people who create computer systems. The first people to call themselves hackers were loyal to an informal social contract called "the hacker ethic." As Steven Levy described it, this ethic include these principles:
- Access to computers should be unlimited and total.
- Always yield to the Hands-On Imperative
- All information should be free.
- Mistrust authority - promote decentralization."
