Introduction to the Singleton pattern in C#

One of the most known, popular patterns in software engineering is the singleton pattern. What is a singleton? A singleton is a class that is written in such a way that it only allows a single instance of itself to be created, and usually has an access method to obtain the instance. You may choose to use a singleton, for example, if your program has some kind of shared resource like an in-memory cache.

Subfactorials — Another twist on Factorials

Let’s look at the subfactorial, which is defined as the derangement of a set of n objects, or a permutation of the elements of a set such that no element will appear in its original position.

Writing D.R.Y. HTML with .Net Helper Classes

There have been far too many times I’ve looked at HTML that I’ve written (and that others have written) where I’ve thought to myself “this is terrible.” Up to 100 lines of code all doing the exact same thing over and over again. If you had to make a change in the code, you’d need to do it on every single occurrence of the code block. Luckily, this can be avoided with HTML .NET Helper classes.
