Getting started

Install VirtualBox guest additions onto Ubuntu server guests

Note

The following steps have been successfully tested with Ubuntu guests of:

24.04LTS
22.04LTS
18.04LTS
16.04LTS

1.) Download a Nerd Font

2.) Unzip and copy to ~/.fonts

3.) Run the command fc-cache -fv to manually rebuild the font cache

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

Install Multiple Java Versions on macOS High Sierra

Install Homebrew Cask

On Mac, Homebrew is the de-facto package manager, and Homebrew Cask is the app manager. I’m going to use Cask to install Java 7 and 8.

Install Homebrew Cask first if you haven’t:

brew update
brew tap caskroom/cask

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
Microsoft Windows 7 SP1 as the host OS
A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

	sudo apt-get update
	sudo apt-get install build-essential git libreadline-dev zlib1g-dev libssl-dev libbz2-dev libsqlite3-dev
	curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer \| bash
	# may need this, but install script above should handle it; and yeah, you can do multiline inserts with awk/sed or whatever
	echo 'export PATH="/root/.pyenv/bin:$PATH"' >> ~/.bashrc
	echo 'eval "$(pyenv init -)"' >> ~/.bashrc
	echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc
	source ~/.bashrc
	pyenv install 3.6.0
