SciBarCamp in Toronto March 15-16
SciBarCamp is weekend unconference for scientists, artists, and technologists. The goal is to create connections between science, entrepreneurs and local businesses, and arts and culture. I think this is a great idea, and wish I could attend (I already have a plane ticket for SIGCSE in Portland); it's free, but there is only space for around 100 people, so please register by sending an email to Jen Dodd.
