Back in April when we launched Java support, we gave the first 10,000 developers who signed up access to the new runtime. In case you havent heard, we recently announced at Google I/O that App Engine for Java signup is now open. Were excited to see more developers joining our community!

For those who missed Google I/O or want a refresher on the sessions, the videos are now posted online. From building a complex and scalable app on App Engine to offline processing, there are a lot of things to learn from these sessions. You can find a more detailed write up of the App Engine sessions in this post to the Google Code Blog, but heres the complete list:

• From Spark Plug to Drive Train: Life of an App Engine Request


• Building Scalable, Complex Apps on App Engine


• Offline Processing on App Engine: a Look Ahead


• The Softer Side Of Schemas - Mapping Java Persistence Standards To the Google App Engine Datastore


• Transactions Across Datacenters (and Other Weekend Projects)


• App Engine Nitty-Gritty: Scalability, Fault Tolerance, and Integrating Amazon EC2


• JRuby and Ioke on Google App Engine for Java


• App Engine: Now Serving Java


• A Design for a Distributed Transaction Layer for Google App Engine


• Connecting The Clouds: Integrating Google App Engine for Java with Force.com


• ThoughtWorks on App Engine for Java: An Enterprise Cumulonimbus?


• Groovy and Grails in App Engine

Apart from the sessions, we also had a Developer Sandbox featuring App Engine partners and customers. We got a chance to interview and ask many of them to share their experience developing on App Engine. Check out these video interviews to get more insight to App Engine:

• 3Scale Networks


• Best Buy


• Caucho Technology


• EZasset


• Gigapan.org


• LifeAware


• LingoSpot


• WalkScore

Last but not least, weve also made available the handy Python cheat sheet we gave out during Google I/O. You can download it here. We want to thank our partners and the App Engine developer community for a fantastic Google I/O 2009! It was great meeting those of you who were there. We look forward to the next year!

At the WWDC 2013 opening session yesterday, Apple WOW the whole world with the new iOS 7 that was unveiled. Although, the rumor of a flat iOS User Interface (UI) had been in the air weeks before the unveiling, yet we were not ready for what was to be. In fact, mock ups were just tardy compared to the original thing.

John Ive, who is the man in charge of this iOS 7 design have made his mark and we are ready to gulp in this new iOS UI. Below are set of images to keep you surprised with your mouth watering.

This iOS 7 is design to be simple, colorful and vibrant. A whole new iOS that will bring out the color and charm in the iPhone, iPad and iPod. 

According to Apple, iOS 7 would only be for iPhone 5, iPhone 4S, iPhone 4, iPod 5th generation, iPad 3, iPad mini. Also, AirDrop is only supported for iPhone 5 and iPad 3.

A small comparison to iOS 7, Android Jelly Bean 4.2 , Windows Phone 8 and Blackberry OS 10

That is our take on this design. It is good, colorful, and thoughtful. A whole lot have been changed: icons, notification centre, multi tasking pane etc. 

What are your opinions?
