So I just got back from an incredibly hectic, amazingly productive three-day trip to Boston, at which I attended Paul Graham's Startup School, had a long meeting about the future of topsl, and gave a talk at Northeastern about the semantics of multilanguage programs. I will have more to say about all these things later, but for now I'd just like to give a big thanks to the folks at Northeastern and the Boston area for coming to my talk and being such a great audience. I've never given a talk before where everyone was so obviously attentive and understanding of what I was presenting, nor have I ever felt so nervous that halfway through the talk someone would raise their hand and destroy my entire talk. Great fun!
