Unless you're deaf and blind and spent the last 24 hours in your closet, you probably heard that there's a volcano with an unpronounceable name in Iceland that's currently erupting. The volcanic ashes are drifting South-East over Scandinavia towards Central Europe. Due to the risk of engine failure, a significant part of the flight traffic in these areas has been entirely shut down.
For a multi-layered set of complex reasons I have to be in Frankfurt on Monday. I am actually officially on vacation next week, no really. This means now I'll be on the road the whole weekend. There's a blogpost on magnetic monopoles in the pipe, but it still needs some cleaning up. Either way, this is just to say, you might not hear from us much for a while.
