Enable git-style colour output in regular diff

Mac OS X

1. Install colordiff using Homebrew:

    brew install colordiff
   

2. Add function to your ~/.bash_profile:

jmar777

var db = connect('localhost:27017/aggr-test');

print('Dropping indexes...');
db.events.dropIndexes();

print('Creating index...');
var indexStart = Date.now();
db.events.ensureIndex({ ts: 1 });
var indexDuration = ((Date.now() - indexStart) / 1000).toFixed(2);
print('Index created (' + indexDuration  + ' seconds)');

EventListener Polyfill

Is IE8 your new IE6? Level the playing field with polyfills.

This script polyfills addEventListener, removeEventListener, and dispatchEvent. It is less than half a kilobyte minified and gzipped.

addEventListener

addEventListener registers a single event listener on a single target.
