I heard from GitHub Two-Factor Authentication](https://github.com/blog/1614-two-factor-authentication) nearly a couple of days ago when I was reading my RSS feed. I enabled it and couldn' push to any of my repositories anymore. Learn in this blog post how to fix it.

Two-Factor Authentication

"Is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network". Github solves this authentication with sending an SMS to a device which wants to push to their platform.

Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

RUN yes | pecl install xdebug \
&amp;&amp; echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" &gt; /usr/local/etc/php/conf.d/xdebug.ini \

	<div id="consolelog" style="font-family: 'Courier New', Courier, monospace; font-size: 12px; margin: 40px 30px 0px; background-color: white; border: 2px solid black; padding: 10px;"></div>

	<input type="text" id="consoleinput" style="margin: 0px 30px; width: 400px;" onkeypress="return evalConsoleInput(event, this.value);" />

	<script type="text/javascript">
	var appendConsole = function(message, type) {
	var color = "black";
	if (type === "error") {
	color = "red";
	} else if (type === "debug") {

	<?php
	# http://jeffreysambells.com/2012/10/25/human-readable-filesize-php
	function human_filesize($bytes, $decimals = 2) {
	$size = array('B','kB','MB','GB','TB','PB','EB','ZB','YB');
	$factor = floor((strlen($bytes) - 1) / 3);
	return sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$size[$factor];
	}

	echo human_filesize(filesize('example.zip'));

	# The command finds the most recent tag that is reachable from a commit.
	# If the tag points to the commit, then only the tag is shown.
	# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object
	# and the abbreviated object name of the most recent commit.
	git describe

	# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
	git describe --abbrev=0
