There's a persistent perception that open source software is being ignored in the enterprise, that they fear it and it ends up being more costly to deploy than proprietary solutions. That's certainly the perception that some major software vendors would like you to have. But it's Jeffrey Hammond's job to dispel those perceptions, at least when they aren't accurate. As an analyst for Forrester Research, Hammond covers the world of software development as well as Web 2.0 and rich internet applications, so he sees how open source is being used on a daily basis. He'll be speaking at OSCON, O'Reilly's Open Source Conference, talking about the true cost of using open source, and he gave us a sample of what's going on in the enterprise at the moment.
