@Foxboron Not meant as argument here and as off-topic as it can ever get, but keynotes is the time when I'm mentally still full-on sleep. No matter what the conference is, there is some "larger than life figure" saying that stuff that does not help me to get on with my life.
Let's just say that I stand in the position that ALL keynotes that I've ever heard in my life did suck, and thus maybe that reason I don't give that much weight to Jack's performance ;-)
I don't even care those Linus' and Dirk chats albeit I respect both (Dirk hired me to Intel so I'm even thankful to him for helping me out when Nokia fell down).
That said, there is one thing I remember Linus saying in LinuxCon EU 2014 that has stuck on me: "If you reach for the starts, you might hit yourself to the moon". That's the only cool thing I've ever heard in any keynote or fireside chat alike session :-)
