23C3: final round of hacker jeopardy. Last years winner Fefe also won this year, what a shame for those others because: the category TFDK was especially there for him. It meant "Things Fefe doesn't know". It was there because he normally wins and they wanted to be sure he can't win this time. Too bad, he won anyway...
BTW, HwTla meant: Hardware with Three Letter Acronyms...
