Powermockito behaving differently on debug
Another issue that took me a long time to figure out. I had a failing test, so I started to investigate the issue with the debugger.

RocketEditor: New Java Swing sample app
Today I present a new small sample application. I did it to quickly create and edit some simple XML files that hold information about a rocket and its different stages. Again, writing a small app like this helped me realize some things about software development. The thing most shocking for me has been how much… Continue reading RocketEditor: New Java Swing sample app

Tsiolkovsky Rocket Equation Java sample app
In a previous post I talked about the Tsiolkovsky rocket equation. Today, I'd like to show you a little app I made. This little app serves two purposes. First, even though it's just a sample app, it can be used to play a bit with the rocket equation. If you do a little research, you can… Continue reading Tsiolkovsky Rocket Equation Java sample app

But there is something really nice that may not be always that obvious: Java is open source. If you wonder how something works, you can not only read the documentation, you… Continue reading A nice thing about Java
