These are great resources for those who have done mobile app development in non-native language like phonegap or titanium mobile (that’s me).
The only thing I hope is wordpress web app is being rewritten in proper PHP framework (symphony, yii etc.) to take advantage of those framework’s architecture. Currently the code getting dirtier and not leveraging new PHP features like namespace, traits, performance improvements etc.
IMO WordPress should start upgrade their codebase to support PHP 5.3 as minimum version required, so that majority of web hosting providers will start upgrading their PHP version too.
