AngularJS ngFocus and ngBlur directives - one way to get them before they get released. Before using, consider re-naming ngFocus and ngBlur to something that doesn't invade the ng namespace, e.g. replace all 'ngFocus' and 'ngBlur' strings with 'ngcFocus' and 'ngcBlur' (where c = cats/custom).
app.directive('ngFocus', ['$parse', function($parse) {
return function(scope, element, attr) {
var fn = $parse(attr['ngFocus']);
element.bind('focus', function(event) {
scope.$apply(function() {
fn(scope, {$event:event});
});
});
}
}]);

Sample node.js server code to implement an XMPP server that will integrate with Android's Google Cloud Messaging (GCM) "device to cloud" message functionality - CCS. This sample only receives upstream messages (i.e. from the device).
var xmpp = require('node-xmpp');
//Set node-xmpp options.
//Replace with your projectID in the jid and your API key in the password
//The key settings for CCS are the last two to force SSL and Plain SASL auth.
var options = {
type: 'client',
jid: '[email protected]',
password: 'XXXXXXXX',
port: 5235,
