Pre scriptum: This was dangling in my drafts forever. I just decided to post it as it is.
One day, some moons ago, I watched a presentation with Linus on Git, and how it would forever change our life. He explained why it’s a must-use on a very big distributed team or/and at a personal level. I mostly agreed. I still thought this was just a clever hack to solve merge conflits on svn and keep changes controlled on a mental level. CVS is dead, SVN is not. For most small teams, SVN is just a shortcut for the common workflow one would do with git, except for one little thing: you commit locally, and publish as needed.
Mercurial, or any DSCM, is great for detaching the act of committing work (accepting it as a valid step towards a goal) from the act of publishing work (putting your modifications up for other parties).
I prefer Mercurial over Git for the polish and supporting the anti-”linus is god” movement. I really didn’t like the way I was told he dismissed the idea of using incremental logs. I’m not being an extremist, or i would use Codeville.
