It's been a while since I've added to this blog; been very busy with some really cool stuff at work (more about that soon).  In the meantime, my latest .NET Matters column in MSDN Magazine is now online at http://msdn.microsoft.com/msdnmag/issues/07/09/NETMatters/default.aspx (cowritten with Shawn Farkas).  If you're interested in randomness and cryptography, check it out.
