if you're still not using any kind of version control in your development projects, you're really doing yourself (and your fellow developers) a disservice. Lorna Mitchell wants to help nudge you down that road. To do this, she's provided a whitepaper about version control systems - what they are, how they're helpful and some cool stuff you can do with them.
Last week I wrote an email to a client who hasn't yet implemented source control, but who is thinking about it. It turned into rather a long email as I attempted to convey WAY too much information in one long email. After some twitter banter, I repackaged my thoughts into a whitepaper on Source Control entitled You're not using source control? Read This! (PDF, no registration needed).
The whitepaper looks at three different tools - Subversion, git and Mercurial (Hg) - and includes a "sales pitch" you can give to the people involved in your project about how it can help them. There's also a few helpful links included at the end for more information about each piece of software.
