Every Tuesday, for the duration of Hacker Beach, will be No Cookie Tuesday. This means that we get together at a hack table, disable all cookies, and use unhosted web apps instead of hosted web apps. The goal of this is to find out first-hand how usable or unusable unhosted web apps are, and improve them where we can. The official handbook of the No Cookie Crew is at https://unhosted.org/adventures.
