Tor is free software that allows a user to have complete anonymity online. It can be used to avoid having websites and applications track your location or attempt to identify you. It does this by routing your network data through a pool of servers around the world, while also stripping identifying information from packet headers.
It's often used to avoid region blocks on the likes of Netflix or YouTube. Some users like it because it prevents ad tracking companies from building a profile on you based on your browsing habits and serving personalized ads. Still, others are just a little paranoid and appreciate the assurance that no one can spy on their internet activity.
You can use Tor on Ubuntu 20.04 Focal Fossa by installing the Tor client. We'll show you how to set it up in this guide, which includes browser configuration and enabling all of your shell commands to run through Tor's network.
In this tutorial you will learn:- How to install Tor on Ubuntu 20.04
- Test your network connection through Tor
- How to Torify your shell temporarily or persistently
- Enable and utilize the Tor control port
- Configure web browser to use Tor network

Kubernetes is leading software in container orchestration. Kubernetes works by managing clusters, which is simply a set of hosts meant for running containerized applications. In order to have a Kubernetes cluster, you need a minimum of two nodes - a master node and a worker node. Of course, you can expand the cluster by adding as many worker nodes as you need.
In this guide, we're going to deploy a Kubernetes cluster consisting of two nodes, both of which are running Ubuntu 20.04 Focal Fossa. Having two nodes in our cluster is the most basic configuration possible, but you'll be able to scale that configuration and add more nodes if you wish.
In this tutorial you will learn:- How to install Docker
- How to install Kubernetes
- How to configure a master and worker node
- How to join a worker node to a Kubernetes cluster
- How to deploy Nginx (or any containerized app) in a Kubernetes cluster

PlayOnLinux is a graphical front end interface for Wine. And if you don't know already, Wine is popular software that allows many Windows applications to run on a Linux system. The problem with Wine is that you sometimes have to do quite a bit of configuration to get a particular application to run; we even have quite a few guides about it on this site.
PlayOnLinux basically hides the complexity of Wine to the user, giving you a graphical interface to work with and automating the installation of many popular applications. Contrast this with just using Wine itself, where you'd inevitably be working with the command line more and have to fiddle around with configuration settings to get stuff working right.
In this guide, we'll show you how to install PlayOnLinux on Ubuntu 20.04 Focal Fossa, as well as go through a rundown of how to install some games and software that you'd ordinarily only find available on Windows.
In this tutorial you will learn:- How to install PlayOnLinux with command line or GUI

Lutris is a game manager built for Linux operating systems, and it does its job incredibly well. It has thousands of games in its catalog and works with very little fuss, allowing you to install games from the cloud and keep them up to date. Most games are "one click install" titles, meaning that you shouldn't have to worry about fiddling with extra configuration to get a Windows game working on Linux. It just works.
Lutris requires Wine in order to ensure a smooth experience. The two work really well together, and that's because the developers of Lutris also work directly with Wine staging. Since the Lutris developers already program their installers to use the most optimal settings possible, there's no need to fool around with Winetricks or any of the usual Wine configuration utilities.
If you're ready to start gaming on Ubuntu 20.04 Focal Fossa, follow along as we setup Lutris and its dependencies on our system.
