The first "Firefox OS App Day Switzerland" provides an introduction to dive into application development for Firefox OS. If you are a web developer you're ready to start - there's nothing you need more.
It is mandatory to register beforehand (it's free): http://firefoxosappdaysch.eventbrite.com/
If you are a web developer interested in creating apps for mobile devices you are at the right place. Talks in the morning will introduce into developing mobile web apps for Firefox OS using Mozilla development tools and proposed tech stack:
09.00 - 09.30 Welcome and intro (Michael Kohler, Henrik Mitsch, Mozilla Reps)
09.35 - 10.20 FirefoxOS app development tools (Marc Bächinger, Mozilla fellow, web developer)
-- break sponsored by Zühlke --
10.50 - 11.10 What users love and widens your reach: Software Localization (Gion-Andri Cantieni, Mozilla Contributor/Firefox i18n Expert and Marc Bächinger, a fluff guy)
11.15 - 11.45 WebAPIs in FirefoxOS and why you as a developer matter (Julian Viereck, Mozilla contributor)
11.50 - 12.35 WebAPI and app distribution (Colin Frei, Mozilla fellow, web developer)
-- lunch break sponsored by Mozilla --
After lunch we build applications for FirefoxOS. Bring your existing mobile web apps to port it to FirefoxOS or start an app from scratch with Mozilla tooling or your own. In a final demo session we present the results of the day to cheer and discuss the things created.
13.30 - 17.00 Hack Jam!
17.00 - 18.00 Demos, awards, discussions, say goodbye
The Firefox Marketplace is looking for open web apps that work well on mobile for Firefox OS, Firefox for Android or iOS. We are interested in all kinds of web apps. You can bring an HTML5 app that you’ve started and want to continue, finish, port, mobilize or just present.
