Lately, I’ve been refining parts of my Linux workflow to make them both more secure and practical. One of those improvements came from something simple but powerful, using encrypted containers instead of relying solely on full-disk encryption.
In this post, I’ll walk you through how I built a secure, self-contained LUKS container on Linux, explain what’s really happening behind the scenes, and share a few lessons learned along the way, including troubleshooting tips and two small Bash scripts that make mounting and unmounting effortless.

How to pass through a GPU and optimize remote performance in Ubuntu
Running a GPU-accelerated remote desktop on a Linux virtual machine (VM) in Microsoft Hyper-V can significantly improve performance for graphical applications, GPU intensive workloads, and even remote testing. However, Hyper-V does not support full PCI passthrough like VMware or Proxmox. Instead, it provides Discrete Device Assignment (DDA), which allows passing a GPU directly to a VM.

Transitioning between Operating Systems can be a challenge. Many aspects of what you’re used to work differently and you should expect a learning curve.
Well, that was a weird intro for a blog post that has Linux networking in the title! Actually I’m saying goodby to Windows as my primary system…. yes you read that correctly. It’s not that I don’t like the system anymore, it’s the direction Microsoft is taking with AI and the integration into the OS that made me take this decision.
Continue readingWelcome to the last of a three part series about Ubuntu and Active Directory. In my previous posts I explained how you could, in just a few steps, join an Ubuntu machine to an Active Directory domain and manage it accordingly. This time I’m addressing centralized management of sudo users. Meaning who can execute commands as sudo on managed Linux desktops (in my case Ubuntu).

In the previous blog post I wrote about how to join a Ubuntu 22.04 machine to a Microsoft Active Directory domain. In this follow up post I want to dive a little deeper into the configuration files, a bug I ran into during testing and setting some advanced security settings for access management. The latter is crazy easy actually, keep on reading.

Sometimes you’ll be needing a setup that includes both Windows and Linux based machines for managing the infrastructure and data processing. Although joining a Windows machine to an Active Directory domain is fairly simple, joining a Linux based systems requires a little more effort. This posts focusses on joining Ubuntu based nodes (Desktop or Server systems) to a Windows Active Directory domain for simplified management and a unified logon experience.

I’m one of those people that tries to use the best tools to do the job at hand. Linux or Windows, both are great in their own respect, both have strengths, both have downsides. This post isn’t about comparing both operating systems, plenty of opinions around for that. Today I want to share the first tip for Linux as I have used it as my daily driver for a couple of years now.
