Thanks a lot for your nice message.

This is weird because I can open the link. Can anyone please double check this? Maybe is google blocked on your side? I can also drop the PDF elsewhere (on some CERNbox or dropbox).

But I just noticed this is the old version of the slides. I am traveling at the moment and cannot thus fix this. I will take care of that from home, tomorrow. Sorry about that and thanks for reporting it to me!
