I'm going to be in Santa Clara, CA, Thursday evening through Sunday morning to attend PyCon US 2013. I'm not presenting, but signed up to be the runner for a scientific Python session on Saturday afternoon. Although I'm working in the humanities, (just between you and me) I'm still a science and engineering type at heart and I haven't found much of a humanities computing presence at PyCon. I hope to see you there.
The conference is moving to Montréal next year. Summer, I hope!
