Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Loopback Alias

Creates an alias on the loopback interface (lo0) with the IP 10.254.254.254 on Mac OS X.

Installation

Install the plist to: /Library/LaunchDaemons/com.runlevel1.lo0.10.254.254.254.plist
Set mode: chmod 0644 /Library/LaunchDaemons/com.runlevel1.lo0.10.254.254.254.plist
Set owner: sudo chown root:wheel /Library/LaunchDaemons/com.runlevel1.lo0.10.254.254.254.plist
Load: sudo launchctl load /Library/LaunchDaemons/com.runlevel1.lo0.10.254.254.254.plist

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

	Reset Steps:
	1. Unplug the desk for 20 seconds. Plug it back in. Wait a full 20 seconds.
	2. Press the up and down buttons until the desk lowers all the way and beeps or 20 seconds pass.
	3. Release both buttons.
	4. Press the down buttons until the desk beeps one more time or 20 seconds pass.
