Sorry, mates, the bug got me. After four days struggling with violent sneezes, corrosive cough, flooding nose and psychedelic fever, I have to give in: this afternoon I'm going to the doctor. The 38,5ºC I have at the moment make it hard to get myself to the office. Therefore, today's tutorials are cancelled, don't turn up, I won't be there.

Hopefully, see you tomorrow....
