Here. Dr. James McCaffrey provides a nice introduction to "permutations" along with some .NET to generate them. He further goes on to use permutations for security purposes, but that's not all they're good for.
Here. The one where I can't believe that .NET Console output isn't buffered by default, then come to appreciate why they did it that way and finally figure out how to turn buffering back on at will, keeping the best of all worlds.
Here. Atif Aziz built a generic VS.NET code generator shim that allows you to build a code generator that plugs into VS.NET by implementing a single method. Cool.
Here. By request, O'Reilly and Assoc. has posted the Format Specifiers appendix from C# in a Nutshell by Drayton et al. It's a wonderful reference to the String.Format/ToString format specifiers that I'm constantly searching for on MSDN. Thanks, ORA!
Here. You haven't lived 'til you've had Don Box call you at home to sing you the fresh lyrics from a new parody to be performed by the Band on the Runtime at the next major MS event. PDC is going to rock.
