Jammy Eggs är marinerade löskokta ägg, som är väldigt gott att dela i två delar och servera med nudlar. Löskokta ägg Jag brukar koka upp saltat vatten med äggen i, och så fort det kokar sätter jag timern på 4 minuter. Efter 4 minuter ta av kastrullen, häll av vattnet, och häll över kallt kranvatten i minst 1 minut, låt sedan vattnet ligga i kastrullen i minst 1 minut innan du skalar äggen…
I’ve used git for well over a decade, sometimes in a team, but mostly on my own. Once again my career has me working on git in a team, so git pull becomes an issue. Thought I’d write this down to help myself transition away from that command. This post is a simplification of git, mostly meant to serve as an aide for myself. git pull is actually two commands When you run git pull it…
Upgrading Fedora Sericea (Atomic Sway) from 42 to 43 I recently had the displeasure of upgrading my Fedora (Atomic Sway) 42 to 43 , and my takeaway from this experience is that Atomic Fedora is not ready for the mainstream. Why do I say that? Well, I used to be a huge advocate for Atomic Linux, ever since I started using it in 2022, my initial view was that the safety of atomic updates would be…
Why so quiet? Short answer, I’ve been focusing a lot on my new job, with IntraPhone Solutions AB. $DAYJOB I’m realizing now that I had stagnated at my old job and was in desperate need for something new. I had been with Telia Cygate for 13 years! I met the love of my life there, and lost her to cancer while still working there. At Telia/Cygate I leveled up a lot, learned so many new…
Vim is funny, I’ve been using it for 25 years but it often feels like I’m only using 10% of its potential. Youtube Video by Henry Misc I found this video by Henry Misc , and it inspired me to write some of his tips down for myself, to remember them better. Quick exit I already knew about ZZ to save and exit, but I need to practice more ZQ to exit without saving, instead of :q! .…
Gitlab I try not to upload any new projects to Github, but the profile is still there with some old content in it. Anything I make is uploaded to Gitlab.com, simply to promote the underdog against the big multinational corporation. my gitlab profile (preferred) my github profile (abandoned) Projects Pluggable Python Prometheus exporter Python RPG “Onward” Ansible Collection for…
This new theme is a world apart from the old theme, but I couldn’t resist redesigning my blog when I found the Academic project page template by Eliahu Horwitz. I know it was made for Academic papers but I just adored the clean design, clear font, everything about it. So I adapted it for Hugo. At the moment it’s bundled into the same repo as my website , the theme is partly hard coded…

Saw this informative video of 7 common mistakes people do when winter camping, so I felt like writing them down on my blog to save them and remember them better. Here is a quick summary. Bring a good sleeping pad that is rated for your expected temperature. Ensure your sleeping bag is rated for slightly lower than the temperature you expect, measured against the “Comfort” rating. Do…
Image from Per Axbom's blog https://axbom.com/fediverse/ I’ll never forget first hearing about StatusNet and GNU Social back in 2017, I was mesmerized. The thought of a social media owned and operated by the people was revolutionary to me. Immediately I started digging into it and registered the domain gnusocial.se, where I deployed my first fediverse node. Not long after that I registered…
I edit this blog in my favorite text editor, vim . Have been using vim since I was a teenager so it’s habitual. After 25 years with Vim I still learn new habits. Today since I was editing a few blog posts at once I realized that long lines in markdown, paragraphs in other words, are the most tiring thing to navigate in vim. So far I’ve been using 55h or 55l to jump 55 characters to…
Image based Linux is an exciting new concept that I have explained further in a previous post . The latest innovation in this field is bootc , that should replace the integral ostree component in Atomic Linux. In this post I will explain how I used bootc to boot a new Fedora image on my laptop. Building Hyprland For my experiment I chose to build the (in)famous window manager Hyprland from source…
Not sure what we should call this relatively new technology that is sweeping the internet right now, but it looks like “image based Linux” is a popular term at Red Hat , Red Hat being one of the main contributors to this tech. I am partial to the name Atomic Linux though, sounds like a powerful new distro. 😉 Endless OS is a Debian variant of image based Linux. I wrote about CoreOS…

Just got the news that Open-source Puppet has been crippled by the parent company Perforce. This is a very hostile move that they’re doing to squeeze more money out of their open source project. And it made me think of me switching from Puppet to Ansible back in 2013, I never regretted this decision. But a lot of people will tell me: Ansible doesn’t scale . That’s true, but you…
Basic logging to stdout import sys import logging logging . basicConfig(stream = sys . stdout, level = logging . INFO) logging . error( "He's dead, Jim" ) As a rule I prefer using the Python logging library for any console output, just because it seems the most consistent. But I rarely can remember how to setup very basic logging to stdout, now I can refer to this post instead of going through old…
Dotnet on Linux wasn’t bad at all, very smooth threshold of entry and it reminds me a lot of Python in its ease of adoption. Thumbs up Microsoft!

I host my CV on my personal website here and of course I always wanted to generate a PDF version of this page, but I could never get the image right so until now I simply deleted the image from the markdown before processing the markdown into PDF. After some Google-Fu I finally solved this issue. Pandoc This tool is powerful but complicated, because it’s a wrapper for many other tools like…

This is how I got into Meshtastic as a European mostly residing in Sweden or Croatia during Q1 of 2024, using a Linux laptop. Purchase device I ordered the WiFi LoRa 32 V3 from heltec.org and they arrived within a few weeks. I would suggest you order at least 3 of them to test the mesh capability. Flashed firmware I used the CLI method in the official docs . Install app Install the Meshtastic app…
This is a weird one but since I don’t have the time or insight necessary to troubleshoot Steam I will simply write how I perceive it. The longer you use Steam, the more it “rots” on disk and eventually breaks. Steam on Linux First of all, disclaimer, Steam and Proton are amazing! I came from the era of Linux gaming where we couldn’t even dream of playing what we do today.…
Use cheat , define your own cheatsheets and manage them with git instead of writing a blog post for each one. So here are mine , on Gitlab.
My parents came from Croatia in the 60s and had 4 children in Sweden, so I’m born and raised as a Swede. Yet I have been to Croatia since I was a newborn baby, my mom once lost me on a train in Croatia in 85, only to find a group of Swedish women she met before had taken care of me the whole time. So I have probably been most summers in Croatia as a child, but I made very few consistent…
Decided to gather some tips on travel here, partly for my own sake, but also because I’m sending a young relative on a trip and was hoping this could help them out.

I already use pass and GnuPG to handle my passwords, but now I wanted to setup the Aerc e-mail client on my laptop. Here’s how I did it on Atomic Fedora Sway 40. Thinking in containers With Atomic Fedora I try to run everything I can in a container, to keep modifications to the host OS down to a minimum. Here’s what I install in a toolbox container. sudo dnf install aerc isync…
I’ve always been a nightowl, for as long as I can remember. Even as a kid 8-10 years old I remember just riding my bike around at night, and staying up very late on my computer. The night is calming to me because my senses get overstimulated easily, and that’s why I get the most done at night.
A summary of what is going on in my life, “now”. Vacation at BornHack 2026 I opted not to camp at bornhack this year but I regretted it as soon as I saw the camp and all the beautiful people. ♥️ But I’ve been enjoying Odense a lot, and I’m going to Horsens tomorrow to explore an island.

I’ve been using AWS many years now for many different things, and it goes without saying that it requires its own set of skills to use correctly. S3 buckets At first there was the danger of public S3 buckets, AWS made a lot of changes to prevent those from being created. Still businesses are leaking patient data and all sorts of goodies on S3 buckets, but at least they can’t say they…
When you for example set shared_buffers=1GB in your postgresql.conf file and then want to verify this setting in a query, or the psql shell, it gets a bit confusing. postgres=# select name,setting,unit from pg_settings where name='shared_buffers'; name | setting | unit ----------------+---------+------ shared_buffers | 131072 | 8kB (1 row) There are two ways to view the correct value. postgres=#…
I don’t normally presume to be competent enough to do a write up of something as technically advanced as the xz backdoor , but this has been such an thrilling moment in IT history that I just had to write my thoughts down to ruminate on them. At the end of the day I’m relieved that the impact was not greater, so now I’m mostly interested in who might be behind it. Instinctively…
Disclaimer: This is just one persons first experience training a JRT. Your mileage may vary. Results I thought I’d start with the positive results my training has lead to. I love my dog and I want her to feel as free as possible in the relatively short time she’s with me. Therefore I want to keep her off-leash as much as possible. This requires her to listen to me, it might save her…
I thought I’d start writing down what I’ve learned since getting my first full-time dog in 2017, so this is the start of a series of posts that will all process one subject each, and try not to be too long-winded. My dogs I am the proud owner of a female Jack Russell Terrier named Smulan, and in 2022 Smulan gave birth to 4 little pups of which another female JRT was given to my mother.…
Avoiding confrontation This is a mistake I see dog owners make very often, so it’s the first thing I want to address in this series. When you encounter another dog and its owner on a walk and you stop before them that signals to your dog that you’re taking part in this confrontation. Whether it be positive or negative, you’ve now decided to engage this new dog and its owner. If…
This might seem confusing to some but it’s actually quite easy, ignore resolvectl and use nmcli to set a DNS for each connection. nmcli con mod "my connection" ipv4.ignore-auto-dns yes nmcli con mod "my connection" ipv4.dns 8.8.4.4,8.8.8.8 nmcli con down "my connection" nmcli con up "my connection" Verify with resolvectl. Change back to DHCP by toggling nmcli con mod "my connection"…
The primary goal with my backups is to quickly restore my laptop to a working state so I can continue performing my duties. This also applies to fresh installs of the OS of course. Files and secrets I run a backup.bash script that mounts a very small 2TB SSD over USB-C, unlock it using LUKS and a long passphrase that I have in my head and then does several backup operations to it. git push of my…
Fedora CoreOS is Fedora’s immutable server distro. Sort of like what Silverblue is for workstations, but for servers and virtual machines that normally run headless containerized services. It’s supposed to be a minimal container host where you are meant to make as few changes as possible to the host FS, config or packages. Everything should run in a container. You can technically use…
I use Terraform to setup Fedora CoreOS VMs in vSphere, and for Terraform to finish VMware tools has to be running so the VM’s IP-address can be discovered and returned via the vSphere API to Terraform. To accomplish this on Fedora CoreOS using Ignition I use this service unit in systemd. [Unit] Description=Layer open-vm-tools with rpm-ostree Wants=network-online.target…

As previously stated; this is a personal blog to document my journey through life, but mostly computers. Disclaimer This blog is highly personal to me, you might even say it’s cathartic to write.

Why write this? For a while I got the feeling that people were using Kubernetes to solve all their problems, I also got swept up in this trend. After 3 years of using Kubernetes professionally and privately, I can finally summarize my thoughts on whether or not it’s the right tool for the job. What is your context? Cloud, on-prem, VMware, oVirt, bare metal? This matters, because Kubernetes…
How to get Gitlab Runner working in a rootless Podman , for a headless service account. Set SElinux to permissive Unfortunately I’ve had to do this to allow the container to connect to the podman socket file. Of course it can be resolved with a custom policy but that’s outside the scope of this short post. I run my runners on their own VMs to mitigate this issue. On any other…
In production I’m deploying Gitlab runners as Quadlets on CoreOS using Terraform, but here is just a short description of how to get it running. You cannot use .container or .volume service unit with Ignition , so you have to define them as ignition_file . At boot the services will be generated. Here is an example of the container unit which we can call gitlab-runner.container and place…
