Install Nvidia Driver on Ubuntu 18.04.3

Secure Boot

This section applies to machines with Secure Boot, such as ThinkPad.

Before installation, switch to "Discrete Graphics" in BIOS, if both Intel and Nvidia graphics are present.
During installation, make sure to select the "Install third-party software for graphics and Wi-Fi hardware and addition media formats" in "Updates and other software" screen.
Select "Configure Secure Boot", and set password.
Continue Ubuntu installation as normal.

Setup modern.ie vagrant boxes

Since modern.ie released vagrant boxes, it' no longer necessary to manually import the ova file to virtualbox, as mentioned here.

However, the guys at modern.ie didn't configured the box to work with WinRM. This how-to addresses that, presenting steps to proper repackage these boxes, adding WinRM support. Additionally configures chocolatey package manager and puppet provisioner.

Pre-requisites

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
