HTML for the Mobile Web, Firefox OS - All Things Open - 2014-10-22

Download to read offline

Firefox OS is a new operating system for mobile phones to bring web connectivity to those who can not get top-of-the-line smartphones. By harvesting the principles of what made the web great and giving developers access to the hardware directly through web standards it will be the step we need to make a real open and affordable mobile web a reality. In this talk, Frédéric Harper from Mozilla will show how Firefox OS works, how to build apps for it and how end users will benefit from this open alternative to other platforms.
