ESRI is having another free MOOC on building apps.  This course will show you how to combine location and narrative in one application to better communicate and broadcast your story, create custom web applications that solve problems in your community, and build powerful native applications for iOS and Android devices without touching a piece of code. If you are a developer, you’ll be interested in ESRI’s APIs, SDKs, and the buzzing GeoDev community.

The free course goes on for 4 weeks (July 20 to August 17) and you will receive a certificate of completion and awards.  Check out the syllabus and sign up if you are interested.
