i think the title "Youtube's star" is an understatement to a fantastic research scholar and a lively personality although he was known to a bigger mass outside the fraternity of computer scientific world through that "last lecture" posted on youtube.

i was fortunate enough to personally interact with the guy - one who defied the odds of this mortal world and 'lived' life to its fullest till its last moment notwithstanding having known he was in the vicinity of its end. great guy.

my heartfelt condolences to his family and to all who knew him. R.I.P.
