Nowadays, being really busy has become something worth bragging about or something you can't escape. 
You will probably even blame your commitments for stealing your time.

But is it truly impossible for you to make time for your "dream project"? 
Are you busy or is it avoidance?

Really. Look at your schedule; and put in a little "dream" time. 
Everything else would benefit more if you spend some time caring for your passions ;)

#JFDI™ (*):

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

The prep-script.sh will setup the latest Node and install the latest perf version on your Linux box.

When you want to generate the flame graph, run the following (folder locations taken from install script):

sudo sysctl kernel.kptr_restrict=0
# May also have to do the following:

sudo sysctl kernel.perf_event_paranoid=0

This gist is no longer in use.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

	// geo-location shim

	// currentely only serves lat/long
	// depends on jQuery

	// doublecheck the ClientLocation results because it may returning null results

	;(function(geolocation){

	if (geolocation) return;
