I'm going to be at the Chicago (Michigan Avenue) Apple Store Monday evening (December 8th) for a talk in their "Meet the Developer" series. The event starts at 7PM, and I think you're supposed to reserve a spot, though it's a store open to the public so anyone can just walk in any time. This is the website for the event:
You have to scroll down and click the "View More" link to see the event. And they (currently at least) list it as lasting from 7:00 to 7:15PM, which is silly, it's actually about an hour long including Q&A. I'm going to talk about Mathematica, iPad apps, and automated quilting and embroidery.
And for those of you who are fans of my more-famous-than-me girlfriend Nina Paley, she's going to be there too, because we're on our way to London together. We're going to bring an example of the quilting work we've been doing together.
