Your terminal setup says a lot about your workflow – in this video, I walk through how I configure my Linux terminal environment, covering tmux, Vim, my Bash configuration, and even a live Ansible provisioning run to deploy this setup across my LLTV servers.
If you’re looking to build a faster, more efficient terminal workflow on Linux, this video covers the core tools I rely on every day as a sysadmin.

What does hacking really look like – and how do attackers actually break into systems? In this video, I sit down with Casey Erdmann, Red Team Engineer and author of Red Team Engineering, to pull back the curtain on how real-world cyberattacks work, what cybersecurity is actually like to learn, and what most people get completely wrong about hacking.
In this video, I’ll walk you through the essential first steps you should take every time you deploy a new Linux server. Whether you’re a seasoned sysadmin or just getting started with Linux server administration, these foundational steps will help you secure your server, set up SSH key authentication, and establish a solid baseline configuration.
Ever wonder what actually happens behind the scenes when I spin up a new server or workstation? In this video, I’m giving you a behind-the-scenes look at my full deployment workflow — covering how I provision cloud VPS servers, configure them with Ansible, deploy workstations, and manage it all through a consistent configuration management approach.
Ansible is a key piece of this puzzle, but this video is really about the bigger picture: how all the pieces fit together to make server and workstation deployment fast, repeatable, and low-maintenance.
Immutable Linux distros are one of the most talked-about concepts in the Linux world right now — but what does “immutable” actually mean, and should you consider switching? In this video, we break down exactly what immutable Linux distros are, how they work under the hood, what technologies power them, and whether they’re the right choice for you.
This isn’t just a buzzword — immutable Linux distros represent a fundamentally different approach to how a Linux system is designed, updated, and protected. Whether you’re a Linux sysadmin, a homelab enthusiast, or just someone curious about where Linux is headed, this explainer will give you a solid foundation.
lnav is a powerful, feature-rich log file viewer for Linux that makes analyzing, searching, and filtering log files far easier than traditional tools like tail and grep. In this tutorial, you’ll learn how to install lnav, navigate its interface, search and filter log files, view multiple logs at once, and tail live log files in real time — all from the command line.
Whether you’re a Linux sysadmin troubleshooting a production server, a homelab enthusiast digging through system logs, or a Linux user who wants a smarter way to read log files, lnav is a tool worth adding to your workflow.
The 2026 System76 Thelio Mira is one of the most interesting Linux desktops on the market — but is it actually worth your money? In this review I cover everything from first boot on Pop!_OS to running Fedora and Debian, real-world benchmarks, gaming performance, and whether this machine deserves a place in your homelab or on your desk.
In this video, I explore how AI can be used for System Administration by integrating Claude Code. I walk through a real experiment where I tested AI against my infrastructure automation workflow to see how useful AI really is for sysadmins.
Is AI a blessing or a curse? Check out the video to learn more about this experiment as well as my findings.
Is Linux uptime really something to brag about? Many system administrators proudly show off servers that haven’t been rebooted in months or even years—but that mindset can actually create serious problems!
In this video, I’ll break down why you might be revealing more than you intended to, and why rebooting your Linux server regularly can actually be a best practice. From applying security updates to maintaining system reliability, avoiding reboots can introduce risks that many sysadmins overlook.
In this tutorial we build an automated Linux backup using rsync and a systemd timer.
In this step-by-step tutorial, we’ll create a reliable rsync backup script, test it safely using dry-run mode, and automate it using a systemd service and timer so your backups run automatically. You’ll also learn how to prevent silent backup failures by adding a mount check, and how to integrate healthchecks.io so you get alerts if your backup script fails.
This tutorial is perfect for Linux users, sysadmins, and homelab enthusiasts who want a simple, reliable, and transparent backup solution without relying on heavy backup software.
