The Cryptoparty / Digital Security Workshop scheduled for this Sunday has been postponed until Saturday, August 31st. That Saturday is the last day of The Public School's weeklong Summer School. The general theme of that day will be Information, so we'll start the day with a Cryptoparty - with hands-on workshops to assist you in generating key signatures, using encrypted and off-the-record chat, and other tools such as Tor and Redphone. We'll wrap up the day with lightning talks ranging from the Electronic Frontier Foundation's work in fighting for civil liberties, discussions of why privacy and security matter, and the Oakland mesh network project.
