There was a talk by James Bach this evening.
The talk itself was OK. But the Question and Answer session was very interesting. Many good points and interesting concepts. "The Law of Leaky Abstractions", Pair Testing, Blink Testing (which is based on the functionality of a certain region of frontal cortex), etc.
From his past presentation, I knew that his background was from exploratory, more like hacking style. With that knowledge in mind, what he said today had good points.
