I gave a fun talk on integrating Oslo's MGrammar and the Dynamic Language Runtime to build your own high-performance, .NET-targeted DSL.

Unfortunately in my time slot I was up against "ASP.NET MVC and World Domination" or something like that, so it was an intimate gathering for my talk... but what we lacked in sheer numbers we made up for in enthusiasm. 

I'll elaborate further on some of the details in a future blog post... for now, here are the slides and code samples.
