Free Software

• 1984 – Richard Stallman started GNU project– Goal: No one pays for software– Eliminate domination by few and

powerful

• To protect “free” created GNU (GNUs not Unix) – General Public License

Free Software Foundation

• General Public License– May copy and distribute software – Cannot prohibit others from doing

same– Cannot charge or restrict licensing– Works derived from licensing must

remain free

Free Software Foundation

• Caused rift between computer industry and free software foundation

• Seemed to be strong anti-business message

• Software companies not interested in free software

Enter Open Source Movement

•Welcome Open Source – (Linus Torvald) greater liberties with licensing Allows use & redistribution without

compensation or credit.

There is great joy in the pursuit of creating something that improves the world. And there is lots of fun involved with doing things you enjoy doing. Open source has become the canvas for great art as well as great science. It is a means of self-expression. And something that facilitates discovering joy.

Embracing Insanity

Linux, Mac and Windows

The social impact of two-way communication, the opportunities for a measure of fame, the recognition of joy in computing, and the ability to contribute something meaningful to others regardless of background are revolutionizing the computer world.

Embracing Insanity

• You can and should shape your own future; because if you don't someone else surely will.

–Joel Barker
