"Mock" Backend for Castle ActiveRecord

Thu, 18 Sep 2008 21:34:36 GMT

Testing code that uses Castle ActiveRecord business objects requires some sort of back end for persistence. This approach allows you to use a "mock" back end with ActiveRecord so that you don't need to rely on a file system or database service to unit test your services.

Yet Another Project Euler Series (YAPES)

Wed, 07 May 2008 02:31:02 GMT

For the past several months, I've been using F# to solve at least two Project Euler problems each week. I find this is a great way to sharpen my math skills and my F# skills simultaneously. If you're looking for a way to flex your programming muscles, you really should check out Project Euler.

Why I Love F#: Lists - The Basics

A wonderful explanation of lists in F#, how they operate, and how to use them.

LINQ Closures May Be Hazardous to Your Health!

Tue, 02 Oct 2007 22:01:02 GMT

This article is really academic in nature on the topic of closures and how they fit into LINQ query expressions. It contains a highly-contrived example that is not representative of quality LINQ code. One of the most interesting aspects of LINQ query expressions is that they produce lexical closures. Exploiting closures in query expressions can be powerful but tricky.

The Art of Currying

Fri, 17 Aug 2007 17:31:02 GMT

This is NOT about food. Haskell Curry came up with a way to melt developer's brains. This is how it is done in C# 3.0

Solving the Problem with Events: Weak Event Handlers

Sat, 24 Mar 2007 19:01:01 GMT

One of the greatest frustration of working with delegates and events is that they can potentially cause memory leaks if they aren't unhooked. In this article, we will solve this problem in a variety of ways to get the best performance, memory use and syntax.

Dustin Campbell: Giving Enums a Little Love

Thu, 31 Aug 2006 11:31:01 GMT

Dustin Campbell (Developer Express' Senior "Whipping Boy") discusses improvements that should be made in order to round out the Enumeration data type in .NET (to provide for both increased functionality and improved readability of code that uses enums).

XmlDataSource: XPath Workaround For Default Namespaces

Mon, 14 Aug 2006 22:01:01 GMT

The ASP.NET 2.0 XmlDataSource does not provide a way to handle namespaces in the source XML. If your source XML uses namespaces, then you need to use XSLT to remove the namespaces, otherwise you won't be able to create a valid XPath statement that will work with the XmlDataSource. Or do you? (hint: you can do everything in XPath without resorting to XSLT)

Day Of Dot Net

Wed, 22 Mar 2006 19:03:14 GMT

Remember http://www.digg.com/technology/_.Net_programmers_are_one_of_the_top_5_most_in-demand_jobs ? Many regions in the US are forming their own community driven conferences. Think Ohio Linux fest, but for .NET instead. Southeastern Michigan is starting off with some excellent speakers (rumored are some DotNetRocks hosts).
