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:

This is a common-jargon walkthrough of an interesting Diablo 2 exploit. It provides the necessary background information (network protocol and game mechanics) to gain some understanding of the primitives from which it's constructed. Since the exploit is against a black-box network service with no available code, exact details and subtleties remain a mystery. :)

Exploit effects

Diablo 2 items can have a list of properties with various effects. The most common items (normal or "white" ones) have very few possible effects; however, all items can have sockets. Rune and gem-type items can be inserted into sockets. Some sequences of runes are special - inserting them into a white item makes a runeword item with predictable special properties.

Here's an example runeword "Peace" created by inserting Shael, Thul, and Amn runes into a 3-socket Light Plate:

[LINUX] Factorio Headless Server Guide

So, with credit to the Factorio wiki and cbednarski's helpful gist, I managed to eventually setup a Factorio headless server. Although, I thought the process could be nailed down/simplified to be a bit more 'tutorialised' and also to document how I got it all working for my future records.

The specific distro/version I'm using for this guide being Ubuntu Server 16.04.1 LTS. Although, that shouldn't matter, as long as your distro supports systemd (just for this guide, not a Factorio headless requirement, although most distros use it as standard now). The version of Factorio I shall be using is 0.14.20, although should work for any version of Factorio 0.14.12 and higher.

Just a note to newcomers: If there are any issues with the installation steps, people in the comments are doing a good job
