I spoke at the O'Reilly Velocity conference this afternoon about using version control to manage web services.
Brian Moon summarized my talk in 140 characters:
“For those that have not gotten the message yet, there is no vcs that does what @ph wants. Your app has to do it. #velocityconf”
I obviously went into a little more detail, including why web applications are different to installed apps, problems that none of the revision control systems solve, and how you can solve some of them yourself within your app.
The slides are online as a PDF file.
