3. Early history • Unix • 1970 – 1990 • Richard Stallman wants a 'free' Un*x clone • writes the GPL (license) – 4 freedoms • Free Software Movement – Free Software Foundation
4. Four essential freedoms • Freedom 0 • To run the program, for any purpose • Freedom 1 • To study • Freedom 2 • To redistribute • Freedom 3 • To distribute modified copies, under the same terms • Access to source is needed (freedom 0, 1 and 2 apply)
5. Rise of Linux • Linux • 1990 – Now • Linus Torvalds use GPL; 'It won't be big announcement' • Linux gets sold commercially – Red Hat, Novell – Adoption by enterprise market • Usage of the word 'free' is ambiguous – Eric S Raymond, Red Hat, et. al introduce a new term – Open Source
6. Open Source • Refers to the freedom to study • Source code is 'freely' available to see • Red Hat starts selling support contracts for OSS
7. Tainted term • Cultural issues between the usage of the terms 'free' and 'open' • Needless discussions • Open Core • Open Source for the core, add-ons are commercially sold • Often the licensing is not ideal to use the core for other projects • Commercial vendors FUD* * Fear, Uncertainty and Doubt
8. 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)
