- 3. 3 Git? • History – Linus – Linux creator, 2005 – Git • Reliable • Fast • Distributed • Content Manager • Suitable for large scale development https://www.youtube.com/watch?v=4XpnKHJAok8
- 4. 4 Tech Talk: Linus Torvalds on git https://www.youtube.com/watch?v=4XpnKHJAok8
- 5. 5 Linux • Commits 491K+ • Contributors 12K+ • Lines of code 16M+ • License GPL v2 • http://www.ohloh.net/p/linux 3/24/2014 • Requirements from Linux – Performance and distributed nature – Security and trust issues
- 6. 6 Why is distributed VCS better? • Distributed vs. Centralized – Offline/Local • Fast – Isolation • Experimental work • No committer right – Reliable: trust and security • Not a single point of failure/natural replication of data • Checksum everything (SHA-1 160bit)
- 7. 7 Art of Git • Make separate commits for logically separate changes. • Describe your changes well. • Use imperative mood • E.g., Fix bug-1234 https://github.com/git/git/blob/master/Documentation/ SubmittingPatches
- 8. 8 Art of Git • Work flow – GitHub Flow • http://guides.github.com/overviews/ flow/ – Create branch – Add commits – Open a pull request – Discuss and review the code – Merge and deploy
- 9. 9 GitHub • Git hosting site. https://github.com/
- 12. 12 Github and Social Coding • Fork and Pull Request – You don’t need a write access privilege. • Collaboration model
- 13. 13 Most of github hosted projects did not have any license. http://www.blackducksoftware.com/resources/infographics/deep-license-data
- 14. 14 Why do we need OSS license? • Collaboration model • Ban Free riders – The Tragedy of the Commons
- 15. 15 Open source and Bazaar • Open source software （OSS） – software license • Bazaar – Software development model – global distributed collaborative work
- 16. 16 How can we choose it? http://choosealicense.com
- 17. 17 OSS Community • Typical OSS community – Charisma, top programmers (e.g., Matsumoto san (Ruby), Linus Torvalds (Linux)) – Committers (top notch programmers who have the right to add/modify the OSS) – Contributors (programmers who submit bug fixes, new proposals, patches) – Casual users (report bugs, ask questions, etc) committers charisma contributors casual users Matz Yugui Linus Greg K Hartman http://commons.wikimedia.org/ wiki/File%3AGreg_Kroah- Hartman_lks08.jpg
