In the article some stuff is different. Sync it please. (Since I am quite new to this I am not sure what is right/makes more sense, so I hope you'll take care of this.)

Since I couldn't find the source code of the article here (in the repository) I thought it would be simplest to fork this repository and comment in the modules what is different, where an error was and what else caused compiler issues.

The rest of the comments is written in log messages.

Besides that I thank you very much that you added this example and I hope that you will continue adding examples for some of the other articles!!! That makes it so much easier to understand the stuff when you have a working example already.
