  • Have We Left Web Radio Behind?

    Since my decision to , I have consciously moved away from Spotify. Instead, I chose to use Navidrome as my personal music server combined with Symfonium as the client. This setup allowed me to rediscover my own MP3 collection — a treasure of gems I hadn’t listened to in years! And I can tell: I really enjoyed the feeling of reconnecting with my personal music library.

  • Goodbye Facebook

    Finally! My Facebook account is deleted.

    My Facebook-Exit is a long story. I never really used it a lot. I used it mostly to have the possibility to contact some people. Especially from university when they went to other countries or so.

  • It’s all about solving problems!

    I am running this blog since 2009. The majority of the time it is dormant, and I mainly use it to document a solution that was hard to figure out and when I wished I had found it earlier. And in case that I have to solve the issue again, I know that I wrote it down here and don’t have to rely on some other website being online in a year or two when I come back to the same problem again.

  • 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.

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

  • 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 . 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 mini computers. My main Pi already runs multiple services like , and – 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.
