For no reason, I was reminded of a simple code snippet to swap (interchange) two numbers that I had discovered in my early programming days. I may have used it once or twice in my 10 years of being a professional software developer.

Swapping two numbers is a common use case when working with some algorithms and the like.

To simplify a process, I had to quickly build a utility app to create report based on status from a large number of emails on a daily basis.

I had always planned to refactor the single Java source file into a proper design when I found some free time. That’s how I got to implement my version of the Pipeline Design Pattern.

As my old colleague felt the usual title for this post “Bye Bye {Year}” to be a bit negative, I have changed it to “Year in Review”, which is what this post ultimately about.
