Once a month, in the Foojay Podcast, we discuss the history of a Java User Group and the people behind it. In this episode, we are in Oberpfalz, Germany, for a particular reason. The organizers of the local JUG are the same people responsible for the JCON conference in Cologne in a few weeks. Let's learn more about the Java community in Germany.
