UPDATE: The correct talk is online now. Thank you very much for this content bug report.
Also big thanks to all reporters in this thread! Your constructive help is much appreciated!
Original Post:
My deepest apologies. The conference LinuxTag (where both talks had been held) had a couple of unannounced room changes. These two talks must have been switched in that fashion.
LinuxTag had six tracks[1], we are currently searching for the right talk to correct this mess!
