How to Allow and Respect Differences in ArgoCD
I’ve been using ArgoCD as my GitOps toolkit for my Kubernetes home lab for many years, nothing major to complain. I wanted to test canary deployment with Argo Rollouts with which Istio is supported.

Arch Linux on Alienware M18R2 and What Works in 2025
As 2024 comes to its end, I decided to try Arch Linux on my new massive Alienware M18R2 laptop. The last time when I tried Arch Linux was years ago so I’d expect it’s much easier to install but probably not as easy as installing Ubuntu or Fedora Preparation To preserve the factory partition with…

It’s been almost 4 years since I started my own Mastodon instance. I took a look at the latest releases and my instance is way behind, so I decided to give v4.3.1 a try. With all the YAMLs and Kustomize stuff I did before, last few upgrades were as simple as a version number change.…

How I Upgraded MongoDB 6 Directly to 8
Long story short, I had a server running Ubuntu 20.04 and unsurprisingly it’s been there for more than 4 years.
