In the Linux Crash Course series, you’ll learn all about a Linux-related topic – one video at a time. In this episode, we explore desktop environments. What are they? How do they differ from Window Managers? Why are there so many of these? Answers to those questions (and more) in this episode of the Linux Crash Course!
OpenStack is an open-source cloud computing platform that enables you to build your very own private cloud that is completely under your control. You can use it to spin up compute instances, set up block and object storage, load balancers, software-defined networking, and more. In this six-part guide, Jay will guide you through the finer points of OpenStack with hands-on examples. In the first episode of the series, we’ll go over a series introduction and outline. In addition, an overview Horizon (the OpenStack dashboard) is covered.

Should you expose your Homelab services to the public Internet? Normally, that will also expose your services to threat actors as well. However, sometimes public access is required for the use-case of a server. Historically, this has been a complicated and debated topic – consisting of technologies such as VPN, Dynamic DNS, and others. Now, Cloudflare has a solution – Cloudflare Tunnels. In this video, Jay and Tom discuss this feature of Cloudflare and will help you determine if it’s a good fit for your homelab.
Live patching enables Linux server administrators to benefit from critical security fixes right now, with the flexibility of rebooting later. There are multiple services that facilitate live patching, and in this video Jay goes over how to set up KernelCare Enterprise for this very purpose. This tutorial will go over what KCE is, how to install it, check for patches, and more!
Thanks to TuxCare for sponsoring today’s video.

NFS (Network File System) is a fantastic way to share files between Linux and UNIX machines. In this video, Jay walks you through the process of setting up an NFS server on Ubuntu, complete with a walkthrough on mounting the exports. Not only that, you’ll see how you can utilize AutoFS for on-demand mounting as well.
Ransomware – an extremely frustrating security threat that can cause business disruption, data loss, as well as long work days during the recovery process. But how do you recover from such an event? In this foundational episode, Jay and Joao discuss some tips on how to deal with this, tips you’ll hopefully never need but are good to have nonetheless.
By using clever infrastructure engineering strategies to increase reliability, you can minimize disruption and downtime for your organization. Another technique to consider is the concept of Digital Twin – having a full system clone/mirror you can use to test enhancements, perform a root-cause analysis, or more. In this episode, Jay and Joao discuss Digital Twins and how the concept can potentially help your organization.
Were you every confused regarding the differences and use-cases between a hostname and domain name for a device within your network? How does naming your servers benefit you? In this latest episode of the Linux Crash Course series, we’ll explore some foundational concepts around both.
System76, a company that focuses on Linux-first computers, designs keyboards now. The Launch Keyboard “launched” some time ago, and for some of you the lack of a numpad was a concern. Now, the “Heavy” variation of the Launch mechanical keyboard is available – and yes, it’s a full keyboard complete with a numpad. In this video, Jay will give you his thoughts on the latest input device from System76.
