  • A new Layout / Theme

    I just switched the theme of the blog to the “Twenty Twenty-Five” theme. I guess I even need to get comfortable with the new look myself.

    A while ago, I noticed that my previously used theme wasn’t customizable in a way that I had the Fediverse reactions in the place I’d like to have it. And after having seen some more blogs in the last weeks (especially via powRSS) – I decided to make the layout even more simplistic.

    Let’s see ow I like it or if I’d like to customize it in some way …

  • Bookwyrm — One Month In

    A month ago, I wrote that I would like to try Bookwyrm (#Bookwyrm: a social network for tracking your reading, talking about books. More on https://joinbookwyrm.com). Now, one month and three books later, it might be a good time to write about my first impressions.

  • The Future is Federated – but not necessarily (fully) Self Hosted

    It’s not a secret that I am quite a fan of the #Fediverse and getting more independent of a few Big Tech Companies and getting control back.

  • How to get the ‘<‘, ‘>’ and ‘|’ keys on a Dell Latitude 5300

    Since a while I am using a refurbed Dell Latitude 5300. I’m pretty happy with it. Just recently I was doing some stuff via SSH on my RaspberryPIs when I noticed that the Dell’s keyboard does not contain the ‘<‘ key. Not a big deal usually – just Linux Shell working is quite uncool without the ‘>’ and the pipe ‘|’ characters.

  • How to solve weird Docker Errors on Ubuntu

    After being so happy about all the services that I brought up last weekend, I forgot to do one thing: rebooting. Today I rebooted for some reason and the containers didn’t came up again.

  • Welcome Wireguard (It’s really always DNS)

    Today I commuted to work and of course wanted to try my new #Navidrome setup that I wrote about before. And – it didn’t work :-( It couldn’t resolve the host name. DNS – again!

  • Migration, Containers and … It’s always DNS, really

    As I wrote in my previous post, I have a new member in the home server environment: The Lenovo ThinkCenter Mini Computer! Right after getting Ubuntu up and running on it, I began the process of easing the workload on my #RaspberryPi. PiHole had been flagging high CPU load a couple of times already, especially when Jellyfin was streaming media and performing its usual tasks.

    The target was clear: keep PiHole on the Pi and move the heavier services to the Lenovo. But I also didn’t simply want to migrate the services. I also wanted to improve the setup …

  • How to Use a Lenovo ThinkCentre M910q as a Powerful Home Server

    As an IT enthusiast, I’ve long been (and still are!) a fan of the #RaspberryPi mini computers. My main Pi already runs multiple services like #PiHole, #Navidrome and #Jellyfin – which often pushes it near its limits. Well, recently I found myself wanting to add even more services to my local network. Unfortunately, my NAS can’t host Docker containers, so expanding compute power became necessary.

  • When Vibe Coding backfires: AI deletes company’s Database

    AI agents “cannot be trusted [and] you need to 100% understand what data they can touch. Because — they will touch it. And you cannot predict what they will do with it.”

    Sounds like the statement of an AI hater — but in fact it’s from Jason Lemkin who was using Replit (an AI powered software development platform) — after it deleted the complete production database.

  • Martin Fowler on “Expert Generalists”

    For a while, I kept asking myself: What’s my technical profile, really?

    I’m not a specialist in one narrow field. But I go deeper in several areas than a typical generalist. So … is that good or bad? Is that a strength – or a flaw, because I’m not “deep enough” in one single thing?
