Put a closure on it

Sometimes you'll have objects that manage state along with event handling. This happens frequently in MVC apps. Let's start with a messy example:

var Launcher = function(rocket) {
  this.rocket = rocket
}

Launcher.prototype.isReady = function() {

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	<!doctype html>
	<html>
	<head>
	<title>iFrame memory leak prevention test</title>
	</head>
	<body>
	<h1>iFrame memory leak prevention test (void)</h1>

	removing it produces a memory leak in some cases. The pattern

	Latency Comparison Numbers (~2012)

	L1 cache reference 0.5 ns
	Branch mispredict 5 ns
	L2 cache reference 7 ns 14x L1 cache
	Mutex lock/unlock 25 ns
	Main memory reference 100 ns 20x L2 cache, 200x L1 cache
	Compress 1K bytes with Zippy 3,000 ns 3 us
	Send 1K bytes over 1 Gbps network 10,000 ns 10 us
	Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD

	// A short snippet for detecting versions of IE in JavaScript
	// without resorting to user-agent sniffing
	// ----------------------------------------------------------
	// If you're not in IE (or IE version is less than 6) then:
	// ie === 0
	// If you're in IE (>=6) then you can determine which version:
	// ie === 7; // IE7
	// Thus, to detect IE:
	// if (ie) {}
