Magento Code Snippets

Download extension manually using mage

./mage config-set preferred_state stable
./mage clear-cache
./mage sync
./mage download community Module_Name

(wherever it says url.com, use your server's domain or IP)

Login to new server as root, then add a deploy user

sudo useradd --create-home -s /bin/bash deploy
sudo adduser deploy sudo
sudo passwd deploy

And Update the new password

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

How long is your average request?
What is the maximum number of simultaneous visitors the site(s) get?
How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log

Best Practices for Azure Redis

Below are a set of best practices that I recommend for most customers. This information is based on my experience helping hundreds of Azure Redis customers investigate various issues.

Configuration and Concepts

Use Standard or Premium Tier for Production systems. The Basic Tier is a single node system with no data replication and no SLA. Also, use at least a C1 cache. C0 caches are really meant for simple dev/test scenarios since they have a shared CPU core, very little memory, are prone to "noisy neighbor", etc.
Remember that Redis is an In-Memory data store. Read this article so that you are aware of scenarios where data loss can occur.
Configure your client library to use a "connect timeout" of at least 10 to 15 seconds, giving the system time to connect even under higher CPU conditions. If your client or server tend to be under high load

	angular.module('myApp', ['ionic', 'myApp.services', 'myApp.controllers'])
	.run(function(DB) {
	DB.init();
	});

	<?php
	//The content which should be parsed
	$content = '<p>Hello, my name is John an my age is [calc-age day="4" month="10" year="1991"].</p>';
	$content .= '<p>Hello, my name is Carol an my age is [calc-age day="26" month="11" year="1996"].</p>';

	//The array with all the shortcode handlers. This is just a regular associative array with anonymous functions as values. A very cool new feature in PHP, just like callbacks in JavaScript or delegates in C#.
	$shortcodes = array(
	"calc-age" => function($data){
	$content = "";
	//Calculate the age

	// inspiration from http://stackoverflow.com/questions/1688657/how-do-i-extract-google-analytics-campaign-data-from-their-cookie-with-javascript
	// readCookie is from // http://www.quirksmode.org/js/cookies.html
	// utmcsr = utm_source
	// utmccn = utm_campaign
	// utmcmd = utm_medium
	// utmctr = utm_term
	// utmcct = utm_content
	var parseAnalyticsCookie = function() {

	var values = {};

	// This will open up a prompt for text to send to a console session on digital ocean
	// Useful for long passwords
	(function () {
	var t = prompt("Enter text to be sent to console, (This wont send the enter keystroke)").split("");
	function f() {

	var character = t.shift();
	var i=[];
	var code = character.charCodeAt();
	var needs_shift = "!@#$%^&*()_+{}:\"<>?~\|".indexOf(character) !== -1
