Jon Udell interviews Bill Crow about HD Photo

On the Friday before MIX, I recorded this podcast with John Lam. He's the creator of RubyCLR and, as it happens, he joined Microsoft on the same day I did. John's been running silent since then, but no longer. In this conversation we discuss the dynamic language runtime (DLR), a generalization of Jim Hugunin's work on IronPython, and a quartet of languages that make use of its services. They include a refactored IronPython, a new managed implementation of JavaScript, Visual Basic, and a new implementation of Ruby which, unlike RubyCLR, does not rely on the C-based Ruby runtime.
We also explore the ability of these languagues to run inside Silverlight-equipped browsers. Key benefits include cross-language interoperability, access to Silverlight's subset of the .NET Framework, and more broadly, a new approach to writing ambitious browser-based software.
