For anyone interested in how branching in Mercurial works, then this blog post by Steve Losh is a must read:
I meant to post this one since last month. Show just how lazy I am…
In my last post, I loudly proclaimed that GitHub is fantastic. Well, after using Mercurial (hg) and Bitbucket for these past few months, I can say that both Mercurial (and Bitbucket) are also fantastic. I especially love the fact that Bitbucket gives you one free private repository to host your private stuffs.
Anyway, If you can, try them out both and see which one you prefer.
Oh, and while you’re at it, why don’t check out my account on Bitbucket?
