Coding Theory (Part 1 of 3) - Coding Theory Defined

Coding theory stands as a cornerstone for most of computer science. However, many programmers today have a diminutive understanding of the field at best. This three-part series of blog posts describes what coding theory is and delves into Richard Hamming’s contributions. Although derived in the 1950s, Hamming’s ideas are so visionary that they still permeate modern coding applications. If a person truly comprehends Hamming’s work, they can fully appreciate coding theory and its significance to computer science.

Turing Machine Simulation in C#

Alan Turing’s idea of building a universal computing machine was truly revolutionary and it changed the face of the world. One extraordinarily simple machine capable of carrying out any computation seems impossible. This blog post is a laconic look at the history and operation of the Universal Turing Machine. The goal is to whet the appetite of the uninitiated and inspire them to seek out a deeper understanding of computation.

Easy Immutable Objects in C#

Change in all things is sweet. - Aristotle

With all due respect to the great philosopher, he obviously never had to write software…

Head on over to Stack Overflow and search for “Immutable Object Patterns in C#” and you will see that this is a point of contention for many developers. Creating immutable objects in C# is cumbersome at best. What if I told you there is a practically effortless way to accomplish this with about one quarter of the code that is used in typical examples. I knew that would get your attention! Hang on tight while I walk you through an exciting demonstration!

Recursion - Good, Bad, or Indifferent

For developers using imperative languages (C, C++, C#, Java, Python, etc…), recursion can seem arcane. It’s just not something encountered regularly. However, recursion is a staple of functional programming. Given the functional programming renaissance, it may be time to “bone up”. Even if you have no interest in learning a functional language, functional concepts have many benefits that can be applied to imperative programming (i.e. LINQ, yeah, who doesn’t LOVE that). This blog post is meant to give a very broad overview of recursion for developers who don’t use it much.

Constructing the SUT (System Under Test) - Eradicating Brittle Unit Tests

I’m not going to proselytize unit testing in this blog post, there are hoards of articles on the internet for that already. Let’s just agree, for arguments sake, that they do awesome things for any software project. In spite of this majesty, brittle unit tests can suck the life out of programmers. There are many reasons for test frailty (a topic for another time), but the main one I’m going after in this piece is adding dependencies. In short, adding a new dependency to any class makes the existing tests fail. Is there anyway of getting around this? Yes there is!
