Commit Early, Commit Often - The Sane Way To Work
A recent post by Ben Collins-Sussman talks about the benefits of frequent commits. This is a must read for all developers that work as part of a team.
Ben talks about some potential benefits to distributed version control, but didn't go into too much detail. All of my source code repositories use Subversion. I often use DVCS as a way to let me work offline. With a DVCS I am able to make very small commits and take advantage of version control when I'm on a plane, in a park or a variety of other places. I am then able to sync up all of my commits as individual commits into the Subversion repository. The trick is to not go more than a day or two in between the syncs.
