A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

	#!/bin/bash

	usage() {
	cat << EOF
	Usage: $0 [OPTION]... COMMAND
	Execute the given command in a way that works safely with cron. This should
	typically be used inside of a cron job definition like so:
	* * * * * $(which "$0") [OPTION]... COMMAND

	Arguments:

	PHP7 is coming

	And it's breaking all of our extensions
	There are currently more changes to the internal apis than there are to things that users will see (and there are enough of those)

	In fact not even all the extensions in php source proper are all the way PHP7'd - most of PECL and extensions hosted elsewhere haven't even started! Heck half don't have maintainers!

	Extensions are also notorious for poor api design, poor testing, and non-existent docs
	But they're also powerful, useful, and fast and more people should use them
	PHP7 is coming - fast - and we have a chance to "break" things and to get the community interested and involved

	# This script is designed to create and mount a single EBS volume based on its tag:Name
	# in order to implement persistent storage. If there is more than one EBS volume
	# with the same tag, this script will fail.
