Currently, I am doing my literature studies for my master thesis about OSGi and PaaS. One of the first books I read was Modular Cloud Apps with OSGi from Paul Baker and Bert Ertman published by O’Reilly. Here is what I think about it. Maybe it is a little bit ironic sometimes, but I hope you get the point.

OpinionTrends is build with Python and Flask. Therefore you can run it without any additional server right out of the box. Batteries included! However, it is much more common and much more efficient if you run it with a web server and an application server. A widely used combination for Python web applications is nginx together with uWSGI. In this tutorial I want to show how we set up this two tools to run TechTrends and OpinionTrends. The tutorial starts at the very beginning and the only thing I assume is that you run a Linux machine with Python and easy_install.

This semester I attended an university course called System Engineering and Management taught by Prof. Walter Kriha. Together with Jan Müller, I build a continuous integration environment for the course. As we were looking for a code review system we found a plattform called GerritHub.io which offered a Gerrit system for GitHub as a service. Here is our experience with this service.

This year there is something new on the Media Night, the student fair at our university.

This semester I attended an university course called System Engineering and Management taught by Prof. Walter Kriha. The course has a slightly different topic every year and is made up of presentations from students, research assistants and other lecturers. The topic in this year was continuous integration and software deployment. Together with Jan Müller, I set up a continuous integration environment to develop a Python web app.

Recently I was putting together some code for an OSGi plugin at work. I created an interface to add listeners to an extension point. The code looked something like this:
