I just created a Docker image that runs the EasyTax2014AG application. It was pretty straight forward to write the Dockerfile. I have based it on the official Ubuntu image because I wanted the Dockerfile to be transparent so that you can actually trust there was nothing installed that tries to steal your data in some… Continue reading Run EasyTax2014 with Docker
Java 8 default methods
Why OK, so interfaces can now provide a default implementation. This makes sense if you want to be able to add new methods to your interface without breaking existing implementations. Oracle uses default methods quiet extensively (see java.util.Collection).

Docker
Lately I had a short presentation about Docker for which I created some slides. The idea was to run the presentation (AngularJS, HTML, CSS) inside a container. You can find the presentation here. Maybe you find it useful.
