// Very often while building a responsive site with bootstrap, you run into the need
// to have half columns.  

// The accepted solution seems to be wrapping the row in yet-another-row http://stackoverflow.com/a/22986836/670023

// But that's annoying when you just need something to be the correct width at a screen size
// and it won't center.

// This hasn't really been tested but _seems_ to work.

// Never do this. Handlers inside of handlers is a Bad Idea regardless of whether they're once or not.

google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
    //this part runs when the mapobject is created and rendered
    google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
        //this part runs when the mapobject shown for the first time
    });

Troubleshooting AWS unauthorized errors in lambda requests

This is mainly for node.js but might apply to other environments. Unsure.

If you are running a AWS Lambda function that calls another AWS service and getting an error about invalid tokens or other access denied errors, do this:

Check IAM

The role assigned to your lambda function will need permission to perform the actions. Check IAM and make sure the role has all the permissions.

// Note: This takes your data keys and drops them directly into the 
// UpdateExpression.  If you have more exotic key names, this will likely 
// fail because 'this is a valid key name' works in javascript but not the 
// dynamodb client.  

var keyName = 'thePartitionKey';
var data = { 
  thePartitionKey: '1231342142321321', 
  message: 'your partial data  i.e. the fields you want updated in the target document' 
};

I'm no expert here so there may be better ways, but this attempts to give a user complete access to a specific region only.  

The first statement covers all resources with ARNs that have the region included.  (Everything except S3 and IAM?)

And the second statement specifically handles s3 and gives complete access to all buckets that end in the target region.

// similar usecase; abbreviated

var myTask = function(callback) {
  var state = { response: false, body: false, other: null }; // only t/f factored when enableNulls

  var req = request('https://...');

// If you're supporting an app built with GWT and running into Invalid Character errors 
// in older version of IE, this patch should fix it with no GWT code changes.
//
// Just include thes script before before including your gwt <script src="app.nocache.js">
//
// Yay. GWT magically working again.  

// NOTE: Does a console.warn "Init document.createElement interception..." prior to running.

// NOTE: If the patch ever encounters an error it will fall back to the native browser
