Freaking prescient. Authentication and security actually is important.

Of course, I’ve been a demo bunny in my time. When I was demoing some crazed graphic app that I helped to port to the new machine the night before and the machine crashed the next day on the floor, I cane up with things like “oh, and this is what a boot demo looks like. It’s storing the problem so you or we can figure out what went wrong. Let’s give a minute and then we’ll continue.”

I was a good booth bunny. But I was never as good as Bill Joy. He was at a major talk when the first slide was the last slide in the talk. He looked at it, and proceeded to natter on through the whole talk, relating it to that last slide as he went, stabbing the last slide concept perfectly into the audience. A demo fail, excellently executed.
