I'll keep bad news short. German embassy in Istanbul rejected to give me a visa and according to some awkward law, they noted that they don't have to tell me about the reason.
This means, I'm not allowed to attend to GUADEC at Stuttgart. Also I won't be able to visit my uncle and cousins in Bochum.
I'm disappointed. The worst is, I'm not able to do anything about it.
Good news is, at least I can watch presentations live over the net.
