Raspberry Pi Setup Guide

This guide will use either a macOS or an ArchLinux base system, to prepare a microSD card with Arch Linux for Raspberry Pi.

If someone managed to do the initial setup using Windows, please let me know, so I can add to this guide.

This guide will be verbose at times for some simple tasks. This is intended to help people just starting out, so it's not confusing. If something confuses you, let me know and I'll try my best to answer it.

Group Array of JavaScript Objects by Key or Property Value

Implementation

const groupBy = key => array =>
  array.reduce((objectsByKeyValue, obj) => {
    const value = obj[key];
    objectsByKeyValue[value] = (objectsByKeyValue[value] || []).concat(obj);
    return objectsByKeyValue;

Ubuntu 16.04 Developer Tools Installation

First things first !

sudo apt update
sudo apt upgrade

Standard Developer Tools

sudo apt-get install build-essential git

Client-side SSL

For excessively paranoid client authentication.
