A/V recording of the talk - varlog.pl
Also - all the code from demonstrations is now published on GitHub, so you could take a look for yourselves (there even is an additional attack I forgot while giving the talk). Thank you for all the kind words - I really appreciate it. Personally I found Pawel's talk much more interesting and I kept taking notes as crazy :) Congratulations to you, Pawel! I'd like to hear your critical feedback on the talk - what one thing could be changed to make it better, were the examples ok, or maybe there was some confusion here and there, which part was boring etc. I'm still learning, although I must say that I really liked the subject presented.
