Noticed that Git is the new king of VCS . Downloaded Git and installed it and going through the manual.
The KEY difference with Git is that most operations are local. Operations like diff ing between previous version of a file are all handled locally. You can commit locally and then upload to the server later.
What does that mean. HUGE SPEED Increase.
Another difference is that Git takes snapshots of the project over time. Looks like it saves the entire file instead of only the difference between files as previous VCS did. That may mean that more HD space is needed but these days that’s not that much of a concern I’d think.
