Configure Incus containers using Ansible

Fri, 13 Feb 2026 13:01:07 +0100

This post will outline how I setup an Ansible playbook to manage a Incus container on a remote host. This was fairly straight forward¹ but I couldn’t find a suitable write-up elsewhere so here we go!

Implementing search on this site

Tue, 27 Jan 2026 09:02:56 +0100

I decided to add a search function to this blog, but this time I had to accept some browser side JavaScript for it to function. This entry will describe how I implemented this (using pagefind) on this site.

Light/dark theme for MermaidJS

Fri, 09 Jan 2026 23:56:46 +0100

Making my graphs respect the user system light- and darkmode settings was surprisingly straight-forward, and we are still not using any (browser side) JavaScript to accomplish this!

Adding icons to Mermaid charts

Sat, 22 Nov 2025 18:00:54 +0100

While we are ricing…enhancing this blog with MermaidJS charts, we might as well add icons to said charts as well! This was also surprisingly easy to do, so here we go…

Upgrading to a new Postgresql major version on NixOS

Thu, 20 Nov 2025 18:50:29 +0100

I’ve seen a few different guides on how to upgrade to a new major PostgreSQL version but couldn’t make it work as I’m also using extensions for some of my databases. Luckily this was relatively easy due to NixOS declarative nature!

Garage object storage, Caddy and dynamically provisioned TLS certificates

Wed, 12 Nov 2025 08:37:00 +0100

I recently started serving this website internally (as a “staging environment”) and discovered that Garage + Caddy can automagically serve sites & issue certificates per S3 bucket, as subdomains under the Garage domain name (*.garage.example.com). This entry will describe how I setup Garage, Caddy and dnsmasq to work together in my homelab setup.

Woodpecker CI, Hugo & MermaidJS

Tue, 11 Nov 2025 21:16:17 +0100

Fiddling around with Woodpecker CI was a lot of fun, so I finally implemented javascript-less MermaidJS graphs! It’s not perfect by any means but I think it is Good Enough(tm) and it involves some terrible regexps so here we go!

Woodpecker CI & Alpine Linux ash

Sun, 09 Nov 2025 11:37:24 +0100

I recently started setting up a new CI/CD environment in my homelab (due to reasons), and this time I decided to test Woodpecker CI¹. It was quite easy to setup, even with both server and agents running in Kubernetes, but I ran into some silly but confusing issues when dealing with environment variables in an Alpine Linux based build step.

Ubiquity EdgeRouter Infinity ER-8-XG

Tue, 21 Oct 2025 15:18:34 +0200

I got my hands on an used Ubiquity EdgeRouter Infinity ER-8-XG this summer, and in this entry I will try to document any discoveries when evaluating this device for homelab use.

And yes, this is overkill even for my homelab ⎛⎝( ` ᢍ ´ )⎠⎞ᵐᵘʰᵃʰᵃ

Disable disk spindown on NixOS

Sun, 19 Oct 2025 09:18:11 +0200

I have two disks in my homelab NAS that would spin down when idle, which puts unnecessary strain on the drives as they are typically woken up again a few minutes later. Disabling this is not very hard, and this pattern is usable for other cases where you want systemd to run multiple instances of something. While all examples below uses NixOS syntax, it’s all just standard systemd components at play.

I initially tried asking a LLM on how to do it and was just provided with a broken, impossible solution so I thought I might as well write this up if someone else needs something similar.
