Prototyping with anonymous classes
In the last post, I presented a rather strange bit of code: public static class ExpressionExtensions { public static Expression<Func<T, TResult>> Expr<T, TResult>( this T item, Expression<Func<T, TResult>> expr) { return expr; } } It looks like a rather pointless … Continue reading
Trivia Friday

As mentioned, I’m learning C, and I’ve achieved hello-world, plus recursive calculations of factorials and some data structures. Whee. :) For those playing along at home, I’ll describe my dev setup. But first, an unexpected discovery: Counter to my intuition, … Continue reading
Dipping into C

A Response To “What Is An Interface” By John Sonmez
this started out as a very lengthy reply to john sonmez’ post on What Is An Interface. There’s enough that I want to say that I think it warrants me posting on my blog instead of blogging in his comment … Continue reading
A Less Ugly Switch Statement For C#
I know switch statements are considered “evil” because they are very procedural code, they violate the Open-Closed Principle, etc etc. But every now and then I don’t see a need to do anything more than a switch statement because the … Continue reading
