Hello,
In my fourth week, I have finished the AppRecommender package and I was able to set the development environment for Apper. I have also contacted the Apper maintaner about the status of the Apper package, and there currently some problems on porting the application to a new KDE framework.
Furthermore, I have also discussed with the AppStream maintainer about my recommendation feature, and he suggested a more practical way to handle the recommendations, which I will also start working.
