Today, Google announced a secure coding contest for it's cloud solution, Google App Engine. From the original post:
Protecting user security and privacy is a huge responsibility, and software security is a big part of it. Learning about new ways to break applications is important, but learning preventative skills to use when building software, like secure design and coding practices, is just as critical. To help promote secure development habits, Google is once again partnering with the organizers of SyScan to host Hardcode, a secure coding contest on the Google App Engine platform.
