Use PHP-CS-Fixer in PHPStorm

Install PHP-CS-Fixer on your local machine according to these instructions: https://github.com/FriendsOfPHP/PHP-CS-Fixer
Open PHPStorm, Preferences > Tools > External Tools and enter these values:
Program, edit to match your path where PHP-CS-Fixer lives: /.composer/vendor/friendsofphp/php-cs-fixer/php-cs-fixer
Parameters: --rules=@PSR2 --verbose fix $FileDir$/$FileName$. Note that previous verions of PHP-CS-Fixer used --levels instead of --rules.
Working directory: $ProjectFileDir$

Click OK and Apply. Now we'll set up a shortcut.

Go to Preferences > Keymap and search for "PHP Fixer" (or whatever name you gave it). Add whatever shortcut you like, I'm using ctrl + cmd + ]:

Using Dnsmasq with Ubuntu for VM web application testing

When running virtual machines under a Linux host system for testing web apps in various browsers (e.g. Internet Explorer), I found it rather tedious having to continually tweak the hosts file within each VM for the purpose of adding entries pointing back to the host machine's development web server address.

Instead the steps below will setup Dnsmasq on a Ubuntu 16.04LTS, 14.04LTS or 12.04LTS host machine for the purpose of serving both it's own DNS queries and that of virtual machine guests. Dnsmasq will parse the /etc/hosts file on your host machine where we will keep a single set of DNS entires to our test web application(s).

Method 1
- Ubuntu 16.04LTS / 14.04LTS
- Ubuntu 12.04LTS
Method 2
- Stop NetworkManager running it's own Dnsmasq

How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

Standalone: replaces the webserver to respond to ACME challenges
Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

1. Configure server: Nginx

Create the certificate:

$ sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt

Create a strong Diffie-Hellman group:

$ sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

	# Colors for the prompt
	blue="\033[0;34m"
	white="\033[0;37m"
	green="\033[0;32m"

	# Brackets needed around non-printable characters in PS1
	ps1_blue='\['"$blue"'\]'
	ps1_green='\['"$green"'\]'
	ps1_white='\['"$white"'\]'

	<?php
	private function get_random_bytes($nb_bytes = 32)
	{
	$bytes = openssl_random_pseudo_bytes($nb_bytes, $strong);
	if (false !== $bytes && true === $strong) {
	return $bytes;
	}
	else {
	throw new \Exception("Unable to generate secure token from OpenSSL.");
	}

	#!/bin/bash
	# Sometimes you need to move your existing git repository
	# to a new remote repository (/new remote origin).
	# Here are a simple and quick steps that does exactly this.
	#
	# Let's assume we call "old repo" the repository you wish
	# to move, and "new repo" the one you wish to move to.
	#
	### Step 1. Make sure you have a local copy of all "old repo"
	### branches and tags.
