Version Control with Git
- 1. Versiebeheer met Git Andrej Koelewijn, IT-eye Jfall 2009, 11 november 2009
- 4. Single point of control
- 5. Security
- 12. SVN Repo thuis niet beschikbaar...
- 14. Lost Git al deze problemen op?
- 15. Why: Linus ● Linus basically applies patches all day
- 20. Gedistribueerd
- 22. Gedistribueerd 3-way merge Snel
- 23. Gedistribueerd 3-way merge Snel Efficient
