With Netbeans 7.4 Beta I have been learning the AngularJS framework in HTML5 and am really impressed with its power to deal with the CRUD (create, read, update, delete) application model. Looks like the latest thing with Google using and supporting the framework. Changes the way on how to do a lots of things done server side moving to the client side.
Also very impressed with the Netbeans integration with the Chrome browser for debugging and testing. Final 7.4 release should have support for PhoneGap which will let web apps become native iOS and Android apps with access to the device features like the camera.
Dang things have came a long ways from the days of coding pads and punch cards! Lots to learn and understand.
