Device motion + websockets demo

iOS 4.2 is finally out and it adds a couple of new important tools to the web developer’s arsenal: websockets and devicemotion. The former makes client/server communication a snap, the latter brings accelerometer support to the browser. I wanted to test both technologies and see what problems might arise. It has been a very interesting experience, here’re my impressions.

Do you really need jQuery (for mobile dev)?

I love jQuery, I use it everyday, you can spot it even on this blog. It’s a life saver in the times of desktop browser discrepancies (yes, I’m talking to you IE), but modern browsers and specifically mobile browsers are good enough not to need any bloated framework on their shoulders. In this post I’m showing you that 90% of the times you are using a framework for nothing.
