  • 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.

  • 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?

  • Rebel Talent – A Book About Smart Nonconformity

    We often think of rebels as rule-breakers. But Rebel Talent by Francesca Gino makes a different argument: the most effective rebels don’t break rules — they challenge conventions. They don’t seek chaos, but creativity. They don’t follow blindly — they question, explore, and rethink. That’s the kind of rebellion this book is about.

  • When AI Writes Code — Who Really Sets the Price?

    AI writing code sounds like every CEO’s dream: cheaper, faster, maybe even better. But what if swapping expensive developers for clever tools just creates a new kind of risk?

  • How to batch migrate Repos from Bitbucket to Codeberg

    When I was browsing through my code archive, I noticed that I was missing some projects and wondered where I had left them after my recent re-install. Just then I noticed that I still had some private repos at Bitbucket. As I just needed a place to back up the code, I decided that I could move it to Codeberg.

    Codeberg describes itself as “[…] a non-profit, community-led effort that provides Git hosting and other services for free and open source projects.”. Codeberg e.V. itself is a registered non-profit association based in Berlin, Germany.

  • Trying Bookwyrm

    Besides programming and all kinds of IT stuff, I really like reading books. Regarding my Calibre library, I am reading between 10 and 20+ books a year. The spectrum covers a couple of IT books but mostly Science Fiction and Fantasy books.

    Bookwyrm?

    And since I joined Mastodon and thus the Fediverse, I came across Bookwyrm a couple of times. Bookwyrm describes itself as “[…] a social network for tracking your reading, talking about books, writing reviews, and discovering what to read next. Federation allows BookWyrm users to join small, trusted communities that can connect with one another, and with other ActivityPub services like Mastodon and Pleroma.“

  • Seems like I’m really off LinkedIn

    I’ve written a couple of times in the past about my goal to leave . The last time was a month ago, when I wrote, ‘I found my replacement for LinkedIn!‘. Since then, I’ve only logged in to add new contacts, to check if it’s someone’s birthday, or to read messages.

  • Loops soon SelfHosting!

    I just saw this post from @dansup announcing self-hosting to be available for Loops “very soon”.

    If you haven’t heard about Loops before: Loops is a short-form video platform designed for the decentralized Fediverse, where users share videos like TikTok.

    Compared to TikTok, Loops offers a few notable advantages: it’s decentralized, so no single company controls the entire platform or its content. Users and communities can (soon) host their own servers and set their own moderation policies. Federation within the Fediverse is not YET there but I’m very sure it will come soon as well..

    I also have an account on Loops since quite early (search “hikingdude”), but I do not (yet) post a lot of videos there. – I’m really considering the self-hosting. Maybe as soon as it’s available – or I wait until YunoHost has it in its app garden.
