How to setup computer

This document describes how I set up my development environment with a fresh install of Xubuntu 16.04 (Xubuntu is Ubuntu with xfce).

Currently this document describes how to set up:

Generic desktop environment with all the goodies (themes, keyboard, utilities).
Python 2 & 3 development with PyCharm.

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso

	# Previous versions of this script don't work because they hadn't been updated since 2012. There are now more steps involved to set this up.

	# This script update is based on information found here: https://developers.linode.com/api/v4/domains-domain-id-records-record-id/#put

	# You first must find out the domain ID and resource ID numbers. In order to do this follow the steps below.
	# 1. Create a Linode API Key through your account profile at https://cloud.linode.com/dashboard. Give it rights to read/write to domains only.
	# 2. From a shell run the following command: LINODE_API_KEY=[insert API key from step 1 here]
	# 3. Run the following command to get the domain ID number for the domain you want to manage: curl -H "Authorization: Bearer $LINODE_API_KEY" https://api.linode.com/v4/domains/

	1. Hit ctrl+alt+esc
	2. Hit Alt+F2, type r, and press Enter
	3. Switch to another tty, for example tty6, by pressing Ctrl+Alt+F6
	Run:
	pkill -HUP -f "cinnamon --replace"
	Return to tty8 by pressing Ctrl+Alt+F8
