Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:

Handlebars.js is a template framework for Javascript environments. It allows the construction of HTML elements using HTML and expressions wrapped in {{ }}

Limitations of {{if}}

One of the conditional block helpers Handlebars offers is the {{#if}}.

<div class="entry">

	<!DOCTYPE HTML>
	<html lang="en-US">
	<head>
	<meta charset="UTF-8">
	<title>test upload by chunk</title>
	</head>
	<body>
	<input type="file" id="f" />

	<script src="script.js"></script>

	static Dictionary<char, double> AnalyseFrequency(string text)
	{
	if (text == null)
	return null;

	Dictionary<char, double> frequencies = new Dictionary<char, double>();
	int textLength = text.Length;

	for (int i = 0; i < textLength; i++)
	{
