I used to use SVN. We built control software for robots. We'd take the robots away on a field trial - no internet access - fix some bugs, write some code, add some features.
That's five to ten people, all writing code that interacts with each other's, all without any access to the SVN server. You can imagine the copy-pasta that went on. The amount of "oh fuck, I just rebuilt-all without Dave's changes". The amount of "Bags not merging this shit."
Then we'd get back to work after a weekend and have to merge all our independent branches. That could take a day or two on its own. Sometimes, sitting with five people's laptops in front of you and using the human brain's visual diff was more efficient than trying to do it properly.
---
Now, with git, we push and pull wherever the hell we like as needed. Everyone's laptop is equivalent to the server. When we get back, everyone merges their stuff into staging, all the cross-dependencies get magically resolved, we test it, and merge that into master. It takes about fifteen minutes.
(Actually, I don't work there any more, but the conclusion works better in the present tense.)
Thanks, that's an interesting example. Yes, I can absolutely see that for truly collaborative projects where multiple programming tasks over the same code portions run in parallel, git becomes a real time saver. I just haven't run into such a project yet myself.
