Ubuntu 16.04 on AWS EC2

This guide enables desktop mode in Ubuntu 16.04 (Xenial Xerus) running off an AWS EC2.

Setup

• Launch an EC2 instance with Ubuntu 16.04 (should work on all versions greater too)
• Ensure a security group is configured, that allows ingress on ports 22 (SSH) and 5901 (VNC, 5900+N, where N is the display number)
• SSH into the instance, update the system, install the XFCE desktop and the lightweight VNC server:

const crypto = require('crypto');

const ENCRYPTION_KEY = process.env.ENCRYPTION_KEY; // Must be 256 bits (32 characters)
const IV_LENGTH = 16; // For AES, this is always 16

function encrypt(text) {
 let iv = crypto.randomBytes(IV_LENGTH);
 let cipher = crypto.createCipheriv('aes-256-cbc', Buffer.from(ENCRYPTION_KEY), iv);

ReactAnimations with animate.css:

Say you want to animate a list of items. Wrap these children components in a <ReactCssTransitionGroup> and set the animation settings (duh) similar to this:

//… the rest of the component declaration
// … this goes in the render function
render: function(){
	var ReactCssTransitionGroup = React.addons.cssTransitionGroup;

Fix SVG in <img> tags not scaling in IE9, IE10, IE11

IE9, IE10, and IE11 don't properly scale SVG files added with img tags when viewBox, width and height attributes are specified. View this codepen on the different browsers.

Image heights will not scale when the images are inside containers narrower than image widths. This can be resolved in 2 ways.

Use sed in bash to remove width and height attributes in SVG files

As per this answer on Stackoverflow, the issue can be resolved by removing just the width and height attributes.

# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.
