Google Developer Days are a chance to learn about Google developer products from the engineers who built them. These one-day events will include seminars and codelabs on web technologies including Google Maps, OpenSocial, Android, Gears, Google Web Toolkit and more.

Here is a video to get you a “warm up” of what is Google Developer day. Notice the free food distribution. This is amongst one of the reasons why I want to be a proud Google employee 😀

Another interesting one is: State of Ajax by Dion Almaer. Check it out on:  http://sites.google.com/site/developerdaylondon/google-developer-day-uk/state-of-ajax

Another event is Google IO. Google I/O is a 2 day developer gathering in San Francisco focused on technical education for building better web applications. With a focus on Google developer products and open source initiatives, sessions span a range of topics relevant to web application developers, including AJAX & Javascript, Maps & Geo, Social applications, Development Tools, and Mobile

Amongst the different sessions, the one I find interesting is: Open Source is Magic by Google Open Source Programs Manager Chris DiBona. Here is the session slide and video.
