It's official: our next open Hack Day will take place June 16th and 17th, Saturday and Sunday, at the Alexandra Palace in London. More information is available now at hackday.org.
Expect U.K. Hack Day to be substantially similar to what we did in Sunnyvale last September, including physical, mental, and psychic sustenance. As before, you need to sign up in advance because space at the venue--especially space on the wireless network at the venue--will be limited, and we want the experience to be outstanding for everyone.
