Dev Derby for January – show us your best orientation!

As you might know, each month we have a Dev Derby as part of Mozilla Developer Network (MDN), and each of them are focused on a certain technology where people can compete with their submissions.

This month, the Dev Derby is about Orientation, and we look forward to some really interesting ideas and demos from you people! And if you’re not already the master of device orientation, you can read up on MDN in the article Detecting device orientation.


Android mobile device
Winner gets an Android mobile device from Motorola or Samsung.
Rickshaw laptop bag
Runner-up gets a hand-crafted laptop messenger bag from Rickshaw.
MDN t-shirt
3rd place gets a limited edition MDN t-shirt to show off their geek cred.

And as if that wasn’t enough, your demo will be showcased in Mozilla’s Demo Studio, and we would like to feature you in an article here on Mozilla Hacks as well!

So, what are you waiting for? :-)

    I own an ARMv6 phone, where Firefox can’t run. So I can’t develop demos because I can’t test them.
    Do you know if Firefox will be ported to ARMv6 before the end of January or if there is any other browser that supports the Orientation API on Android? (or if I can test demos in other ways?)

      I see. Currently I don’t know whether support for ARMv6-based phones is in the planning right now. You could potentially test it in Firefox on some laptops if they have an accelerometer.

    Thank you, Robert. Sadly I don’t own a laptop with an accelerometer, so I’ll simply miss this dev derby, that was also my favourite one, as I had a lot of ideas :(
    There’s bug 697205 about ARMv6 support, I hope it will get some love :)
