I was supposed to give a talk in Amsterdam yesterday, but as the airlines would have it, there was no such luck.
I got as far as Houston in my trans-continental journey before being stymied by aggregated air travel stupidity. Luckily, Andy Smith of Flock fame stepped into the breech and gave the talk in my place.
The talk was written out ahead of time and Andy can read better than I ever could, so I assume it went as well as possible. At least he didn't report any sharp objects being thrown at him afterward.
The text of the talk is here.
