fianlly some rain

Back at work after the mini break I mostly worked on next week's second teaching session. It's half-way there. In the afternoon I took the train to Potsdam to attend the local deRSE meeting. Today's focus was on testing scientific software. I learned some new bits. As always the networking was really useful. I was a little late to catch the train and got thoroughly soaked. The rain was well needed. I am not sure why there are no cars. Maybe they are not waterproof. I did make it to the meeting on time in the end.
