Published on

If you are like me, your spectrum of interest is large when it comes to technology. You may be a Python developer, but that does not mean you have not any interest in HTML, and it’s a good coincidence as it’s the foundation of my presentation. In this talk, Frédéric Harper will show you how you can use HTML5 with the power of JavaScript to build amazing mobile applications as to brush up what you previously published. Learn about the open web technologies, including WebAPIs, and tools designed to get you started developing HTML apps for Firefox OS, and the web.
