copied!<blockquote> <p>To those who think distributed systems don't allow authoritative copies please note that there are plenty of places where distributed systems have authoritative copies, the perfect example is probably Linus' kernel tree. Sure lots of people have their own trees but almost all of them flow toward Linus' tree.</p> <p>That said I use to think that distributed SCM's were only useful for lots of developers doing different things but recently have decided that anything a centralized repository can do a distributed one can do better.</p> <p>For example, say you are a solo developer working on your own personal project. A centralized repository might be an obvious choice but consider this scenario. You are away from network access (on a plane, at a park, etc) and want to work on your project. You have your local copy so you can do work fine but you really want to commit because you have finished one feature and want to move on to another, or you found a bug to fix or whatever. The point is that with a centralized repo you end up either mashing all the changes together and commiting them in a non-logical changeset or you manually split them out later. </p> <p>With a distributed repo you go on business as usual, commit, move on, when you have net access again you push to your "one true repo" and nothing changed.</p> <p>Not to mention the other nice thing about distributed repos: full history available always. You need to look at the revision logs when away from the net? You need to annotate the source to see how a bug was introduced? All possible with distributed repos.</p> <p>Please please don't believe that distributed vs centralized is about ownership or authoritative copies or anything like that. The reality is distributed is the next step in evolution of SCM's.</p> </blockquote>
