LASCON is happening in Austin at the end of October. There are great sessions on development, devops, attacks, and architecture. There will be speakers from cloud and devops companies like Etsy and Netflix with lots of talks on open source tech like Railsgoat (a vulnerable web app written in ruby on rails) and Threadfix.
