Welcome to the thirty-third edition of Community Convergence. This week we have a new video called Programming in the Age of Concurrency featuring Anders Hejlsberg and parallel computing wunderkind Joe Duffy. In another context, Joe reminds us that there is a Parallel computing CTP planned for later in 2007. He recommends watching his blog if you want updates on this anticipated release. On a somewhat lighter note, there is also an amazing post from Luke Hoban, who has written a LINQ query that implements the Ray Tracing algorithm. See also the links to the ALT.NET controversy included in the "From the C# Community" section of this post.
