##0. Mass Assignment

Mass assignment allows us to set a bunch of attributes at once:

attrs = {	:first => "John", :last => "Doe", 
			:email => "[email protected]"}
user = User.new(attrs)

jq is useful to slice, filter, map and transform structured json data.

brew install jq

	# OBJECTIVE: Install Arch Linux with encrypted root and swap filesystems and boot from UEFI.

	# Note this encrypted installation method, while perfectly correct and highly secure, CANNOT support encrypted /boot and
	# also CANNOT be subsequently converted to support an encrypted /boot!!! A CLEAN INSTALL will be required!

	# Therefore, if you want to have an encrypted /boot or will want an encrypted /boot system at some point in the future,
	# please ONLY follow my encrypted /boot installation guide, which lives here:

	Installing Arch:


	sudo vim /etc/pacman.conf
	Update packages list: sudo pacman -Syy
	run sudo pacman -Syu before installing any software (to update the repositories first)

	* Timing issue:
	- Change hardware clock to use UTC time:
	sudo timedatectl set-local-rtc 0

	import functools
