Open Source is one of the core tenets of the PHP language and the community. PHP would not be here if it was not for some of the ideals around software development that occurred in the 50's, 60's, and 70's. How did the open source movement start, and why is PHP one of the few languages that still hold true to those early days of programming? Let's talk about where open source started, and find out how we got here.

12. The 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

“I consider that the golden rule requires that if I like a
program I must share it with other people who like it.
Software sellers want to divide the users and conquer
them, making each user agree not to share with others. I
refuse to break solidarity with other users in this way.
I cannot in good conscience sign a nondisclosure
agreement or a software license agreement. For years I
worked within the Artificial Intelligence Lab to resist such
tendencies and other inhospitalities, but eventually they
had gone too far:
I could not remain in an institution where such things are
done for me against my will.”
