git init: Say Hello to Agility
Posted by Jason Rudolph on 22nd April 2008
With all the recent fuss about the game-changing advantages of Git and distributed version control in general, it would be easy to overlook what Git does for deciding whether (and when) to use version control for a given task. Sure, Git makes non-linear development a breeze, it manages large projects with uncanny efficiency, and we probably can’t even fathom yet just how transforming github is going to be for open source. But, if you look closely, there’s something worth noting way before you create your first branch, before your project is even thirty minutes old, and well before you’re ready to share it with the community: git init is so pleasantly simple, you’ll never again think twice about “whether it’s worth it” to throw something into version control.
As someone who had the, um, “joy,” of working with CVS, SourceSafe, ClearCase, and other SCM “solutions” that made you wish you were instead just using NTFS, I definitely appreciate what SVN did for the state of version control systems. Nevertheless, there were countless prototypes, drafts, experiments, etc. that I talked myself out of storing in SVN. The conversation typically went something like so: “Do I really want to create a new repository just for this experiment? Should it go in my local repo, or does it belong up on the shared repo? Should I bother setting up the standard dirs for trunk, tags, and branches? Maybe I should just add it to a grab-bag repo for now? Nah. Forget it. It’s not worth the trouble yet.”
Git removes many of those decisions altogether, and (in true agile fashion) it allows me to defer the others until they actually matter. I can “execute, build momentum, and move on.” Let’s say I’m halfway through a blog post, and I decide that I want to try taking it in a different direction. No problem. Drop it in Git, and experiment away…

So while you’ll continue to hear people (myself included) champion Git’s importance as a solution for team-based or community-based development, its ability to give you instant, no-questions-asked version control is enough to earn a place for Git on your system, even if you’re the only one who will ever see your work.
And Git’s agility doesn’t stop there. From branching on a dime, to the oh-so-beautiful stash, to the ability to rework past commits, Git reminds me that decisions are temporary. Or, to quote Ryan Tomayko, “Git means never having to say, ‘you should have.’”
