By the light of Dynamic Silverlight

Keeping secrets is tough. Hearing about the Dynamic Language Runtime (DLR) from John Lam in February this year was one of those secrets that kept well.

John Udell interviewed John Lam, and has a backgrounder here. Some in the Ruby community didn’t see this coming.

Jim Hugunin has a posting on the new DLR, open source nature of the DLR on his «Thinking Dynamically» blog.

In addition to the Silverlight release, we’ve also made the full source code for both IronPython and all of the new DLR platform code available on codeplex under the BSD-style Microsoft Permissive License. All of that code can be downloaded today as part of the IronPython project at

The reality of being able to debug Ruby in a client-side UI framework on Safari on a Mac using Microsoft Silverlight tickles me, and others, greatly.

Blog from the keynote today, with all the ups-and-downs. Good to see I am not the only one who craves demos and has subversive thoughts in the midst of formal sessions.

Ryan Stewart has comments, and further links. The DLR adds 400K (what the!) to the Silverlight download. Wow.

zdnet has a sort of transcript of the Q&A that occured with Mike Arrington, Ray Ozzie and Scottgu.

Does Microsoft get Web 2.0? Yes.
