What Linux distributions, hardware, and software do I actually use? In this video, I share some of the Linux distros, laptops, desktops, server operating systems, and applications that currently support my workflow.
You’ll learn which Linux distributions I’ve been using lately, why keeping an alternative distro in mind can be useful, and which distro I prefer for Linux servers. I’ll also show you some of my current computer hardware and briefly discuss several Linux apps and tools I use.
GB vs GiB and TB vs TiB—what’s the difference? Learn why storage sizes often appear incorrect, how SI and IEC prefixes work, and which units accurately describe your SSD, hard drive, and computer storage.
Just installed Arch Linux? This Arch Linux post-install guide covers 10 essential steps for building a secure, optimized, and fully functional desktop – including Pacman, Flatpak, CPU microcode, firewall configuration, SSD TRIM, multimedia codecs, Bluetooth, printers,the AUR and more!
Learn how to create a Linux VPS on Linode from start to finish in this beginner-friendly tutorial. I’ll walk you through deploying a Linode instance, choosing the best data-center region, selecting a Linux distribution, comparing VPS plans and costs, and configuring your server.
You’ll also learn how to enable Linode’s optional backup service and securely access your new Linux server using both the browser-based Lish console and SSH. Whether you’re building a web server, development environment, home lab, or cloud-hosted Linux project, this guide will help you get started quickly.

(more…)Learn how to secure an Ubuntu server with UFW (Uncomplicated Firewall) in this complete, hands-on Linux firewall tutorial. We’ll install UFW, configure secure default policies, create firewall rules, protect SSH, allow Apache traffic, limit connections, manage subnets and port ranges, enable logging, and explore the GUFW graphical interface.
Whether you’re a Linux beginner, system administrator, homelab enthusiast, or server administrator, this practical guide will help you understand how UFW works and how to use it safely. You’ll also learn the difference between deny and reject, how to check active rules, and how rate limiting can help protect SSH against brute-force attacks.
Learn how to install SteamOS on a desktop PC and transform your computer into a dedicated, console-style gaming rig. This step-by-step SteamOS installation guide covers compatible hardware, system requirements, creating a bootable USB installer, booting the installation media, and installing SteamOS from start to finish.
Whether you’re building a custom Steam Machine, repurposing an old gaming PC, or looking for a Linux gaming alternative to Windows, this tutorial will help you get started.
Do you actually know how fast your network is? Not what your switch spec sheet says — what it’s really doing between two hosts. iPerf3 is the tool sysadmins and homelab enthusiasts reach for when they need real answers, and in this video I’ll show you how to use it from the ground up.
We cover everything from installation to practical usage, including how to test WiFi vs wired, push a 10 gigabit ethernet connection, bind to a specific interface, and dial in your test parameters for accurate results.
If you’ve ever rebooted a Linux server and had it fail to come back up, there’s a good chance the culprit is sitting right in your /etc/fstab file. Device names like /dev/sda1 can shift after a reboot, a drive swap, or even a kernel update — and when that happens, your mounts break and your server may not boot at all. In this video, I break down why UUIDs matter for Linux storage, and I show you a real production server that ran into exactly this problem.
Manually spinning up VMs in Proxmox gets old fast. In this video, I’m using Kestra (an open-source workflow automation platform) to automatically clone a VM template and start it, all without touching the Proxmox UI! You’ll see the process of buiding the workflow, setting up the Proxmox API – and more! In this step-by-step video, you’ll be able to build this for yourself.
Thanks to Kestra for supporting this tutorial! You can self-host it and use it to automate entire workflows , so check it out!
