I enjoyed a week of Easter holiday on the North Sea island Spiekeroog. It was very nice, except that I fell ill and had to spent 3 days in bed. On the way back we visited a friend of Almut in Hannover (hello Almuth!!) before flying back. Wow, it's incredible how many e-mails arrive when you are not looking :-). Working through these now. On a unrelated note: our University server (uptime of 420 days) will need to be rebooted to upgrade to the new Debian release. *sigh*
