Linus on Subversion, GPL3, Microsoft and More
victor77 writes "Linus has repeatedly slammed Subversion and CVS, questioning their basic architecture. Subversion community has responded...how valid is Linus's statement?" This and many other subjects are covered in this interview with Linus.
He did slam CVS indeed, SVN likewise. In Linux talk at Google about Git[video] he mentions SVN and their credo at on time being something along the line of "CVS done right", commenting that "there is no way to do CVS right."
The article linked here is light on details concerning SCM, though.
Indeed!
Damnit, it's a paradigm shift that Linus is talking about. True distributed source code management brings an entirely new way of working. It enables very fast merging at a very fine granularity, which lets you use casually use this information (about what changed and when) in a way that changes the nature of how you work! It's the same sort of difference that code completion or Google search made. Once a certain kind of very useful information -- that has always been available, but a bit inconveniently -- becomes like running water out of the tap, it enables ways of working that just wouldn't have been practical before.

If you really want to know what Linus is talking about from the man himself, watch this Google Tech Talk. It's over an hour, but there's nothing like hearing it straight from the horse's mouth.

I used to use CVS (and still do for some projects). Then I switched over to SVN. It was remarkably unremarkable.
Then, a few months ago, there was a /. article on git. It sounded interesting so I tried it... and was thoroughly impressed.
I was up and running in about 20 minutes. You can use cvs/svn like commands, *but* you get local / decentralized repositories with fast forking and merging.
Start a project. Type "git init" and you've got a repository in place (you don't have to initialize and then check it out). "git add ." and "git commit" and you've got your first revision.
It took a little bit more effort to figure out how to push/pull from a remote repository, but it's fairly straightforward. A bunch of people can work in a group, have their own local repositories, and then merge their changes (along with the revision history). It's awesome.
The only reason I haven't switched all of my projects over to it is that the IDEs I use (Xcode and Eclipse) don't have good git integration (as far as I know).
