Podcast: John Lam on the DLR (Dynamic Language Runtime), IronPython, IronRuby And RubyCLR

DotNetRocks has published their latest podcast: John Lam on the DLR.
From the site:

John Lam talks to Carl and Richard about his trek from Canada to Redmond, and his work on dynamic languages, including Ruby CLR, and the Microsoft DLR (Dynamic Language Runtime), which we may find in some future version of the .NET Framework.

John recently emigrated from Canada to the Microsoft Republic to join the Dynamic Language Runtime team. He works on the IronRuby implementation, and pitches in where necessary on the DLR, and on integration with partners like the Silverlight team. Before he joined Microsoft, he created RubyCLR, an innovative high performance open-source bridge between the Ruby interpreter and the CLR. You can track what John is doing with IronRuby and the DLR via his blog: http://www.iunknown.com.
