I had 3 weeks off. During this time, I did a few excursions around Yorkshire, travelled on a steam train, took tons of pictures and videos. August was quite nice, with no really hot day (max temperature was 25C), but with some nice sunny days. I also used the time to familiarise myself with the Diffie-Hellman-Merkle algorithm, which allows to create a secure shared key for encryption/decryption, which is generated simultaneously on the client and the server, and does not need to be sent between them - allowing data to be sent encrypted over an insecure connection.
Now since Tuesday I am back in my office. I still have to solve that mystery why on some days exactly at 7:04 in the morning my PC shuts down... some mysterious remote control from the IT dept?
Did a few reviews for a conference (ISVC), wrote a referee report about an applicant due to promotion (at a foreign university), otherwise did just slacking off. Could watch during the daytime at 15:00 episodes of the US TV series Monk which is about a detective with some serious obsessive-compulsive disorder - one of my favourite programs while I lived in the US.
Now the daytime program for me takes place in my office, or in meetings. And a long list of things to do: preparation of teaching material, writing one or two paper manuscripts, preparation of a workshop. And of course apply for funding of my research work activities.
