Unit Tests: Searching under the Lamp Post

I’m a big fan of unit tests (Surprise). When ever possible I practice TDD. I like how that approach coerces me into making smaller classes, less dependencies, cleaner abstractions. And of course I love it when my unit tests catch a regression before I even start the application.

Algorithm of the Week: Data Compression with Prefix Encoding

Prefix encoding, sometimes called front encoding, is yet another algorithm that tries to remove duplicated data in order to reduce its size. Its principles are simple, however this algorithm tends to be difficult to implement. The good thing is that this algorithm can be used in many cases once we know the data format in advance. So here are three examples where this algorithm can be very handy.
