I’ve used git for well over a decade, sometimes in a team, but mostly on my own.

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 so quiet?

Vim is funny, I’ve been using it for 25 years but it often feels like I’m only using 10% of its potential.

Gitlab I try not to upload any new projects to Github, but the profile is still there with some old content in it.

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.

Just because my wifi router supported WPA3 I assumed my laptop was using it but apparently it requires a simple setting in NetworkManager. nmcli con mod my-wifi-connection wifi-sec.key-mgmt sae nmcli con down my-wifi-connection nmcli con up my-wifi-connec…

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.

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.

I edit this blog in my favorite text editor, vim.

Image based Linux is an exciting new concept that I have explained further in a previous post.

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 just noticed this message when I was installing a new package with rpm-ostree.

Just got the news that Open-source Puppet has been crippled by the parent company Perforce.

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 consis…

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.

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 making this a few times it’s a super quick way to get a nice breakfast treat.

This is how I got into Meshtastic as a European mostly residing in Sweden or Croatia during Q1 of 2024, using a Linux laptop.

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.

Use cheat, define your own cheatsheets and manage them with git instead of writing a blog post for each one.

My parents came from Croatia in the 60s and had 4 children in Sweden, so I’m born and raised as a Swede.

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’m not claiming this for Croatia, but I get this with my burek at my local bakery every morning.

I already use pass and GnuPG to handle my passwords, but now I wanted to setup the Aerc e-mail client on my laptop.

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'; n…

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.

Disclaimer: This is just one persons first experience training a JRT.

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.

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.

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…

The primary goal with my backups is to quickly restore my laptop to a working state so I can continue performing my duties.

Fedora CoreOS is Fedora’s immutable server distro.

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.

A brief description of my current working setup.

As previously stated; this is a personal blog to document my journey through life, but mostly computers.

How to get Gitlab Runner working in a rootless Podman, for a headless service account.

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.
