  • A New Era of Social Media – Video by Elena Rossini

    If you are not following Elena Rossini, you might have missed her really great video about the Fediverse. I find it a very nice and clean way – not focusing on technology but on us, the users. She doesn’t lecture or explain too much – she just shares what she’s found: a space that feels…

  • PeerTube and Platform Control

    I didn’t even plan to blog something today, but a couple of things came together around PeerTube that convinced me to drop a post today. But, maybe before we start … PeerWHAT? you might ask. Interlude: What is PeerTube? TL;DR: An open source / self hosted YouTube PeerTube is a video platform that works a…

  • DNS4EU: a private, safe, and independent European DNS resolver

    Recently I switched my DNS Resolver to one of the European public DNS resolvers | European Alternatives mainly for privacy reasons after reading Cloudflare’s blog post about analytics in their free-tiers.

    We’ve heard it all a couple of times: “GenAI is replacing Software Developers”, Vibe Coding, … A C-Levels dream to (finally) get rid of expensive software developers by using AI.

    Recently I thought “If AI scrapers are scraping my website, would a prompt injection work? Just adding invisible Prompt commands …?” And just today, a colleague sent me this link to an article about prompt injection in GitLab Duo: Remote Prompt Injection in GitLab Duo Leads to Source Code Theft: TL;DR: A hidden comment was enough…

  • Why “Open” may not Always be Enough

    If you care about open source, open data, or open standards, you should read “What we in the open world are messing up in trying to compete with big tech“. I found it a good critique on Open Source and why “technology” and an OpenSource Licence may not be enough to compete with BigTech players.…

  • Buchempfehlung: Die Logik des Mißlingens

    Eine Kollegin hat mir neulich ein Buch empfohlen: “Die Logik des Mißlingens, Strategisches Denken in komplexen Situationen” von Dietrich Dörner. Klang ja wie eine Anleitung für Projektleitung. Kurz darauf lag also eine leicht vergilbte second-hand Ausgabe davon auf meinem Tisch. “Die Logik des Mißlingens” ist kein neues Buch – es ist von 1989, aber ein…

  • Podcast: Warum Arbeit häufig Zeitverschwendung ist

    Gerade von Kollegen empfohlen bekommen: eine Podcast Folge über Arbeit und Meetings. – Wird irgendwie nie alt.

  • How to check the Email Security Level of your Provider

    If you’ve ever wondered which security protocols your email-provider supports, there is an easy way that I found via Mastodon: The European Commision provides My Email Communications Security Assessment (MECSA) (https://mecsa.jrc.ec.europa.eu/) with which you can quickly check, which of the protocols your provider supports (StartTLS, x509 Ceerts, SPF, DKIM, DMARC, DANE, DNSSEC).

  • How to delete all content from LinkedIn

    As I’ve written earlier, I’m going more and more away from LinkedIn (like here and here). During my #unplugTrump activity, I decided that I want to go a step further and remove all my content (posts, answers, likes) from LinkedIn. On Mastodon, I have auto-delete activated already for various reasons. Now I wanted to clean…
