Rise of Linux
● Linux● 1990 – Now● Linus Torvalds use GPL; 'It won't be big
announcement'● Linux gets sold commercially

Tainted term

commercially sold● Often the licensing is not ideal to use the core for
other projects

Open, beyond Source
● Open Source is mostly an ideal; way of thinking● Promotes collaboration/sharing of ideas● Licensing promotes re-use of material
– Creative Commons (Lawrence Lessig)
● Open Education is a good example● OpenCourseWare (MIT)● Wikipedia (WikiMedia foundation, uses CC)● TeachingOpensource.org
● Open Source Way (http://theopensourceway.org)
