  • Comment Sections do not need to suck (maybe)

    Recently I read the blog post Why Comment Sections suck – re:I want to comment on your blog post | Kami’s Corner. The article discusses the various problems of comment sections in blogs. And actually, I wondered if a Fediverse-integration couldn’t address some of those issues:

  • Numa Hack: When “Access Control” is just a Number in a URL

    Not long ago, I covered the Merkur hack from Lilith Wittmann – a glaring example of careless handling of sensitive data. And today, here we are again! Another service, another broken-by-design system. This time: the hotel chain Numa, exposing tens of thousands of identity documents to anyone with a URL and a browser. What happened I…

  • 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. But I missed the malware protection. But today I just got aware of DNS4EU For Public! DNS4EU is an initiative by the European Commission…

  • Is it finally over for Developers?!

    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.

  • Take Back the Stream: Support PeerTube’s Mobile App

    Big Tech dominates online video. Algorithms, Ads, and tracking define what we see and who gets heard. PeerTube offers a real alternative – decentralized, open-source, and powered by its users, not corporations. Now, PeerTube is taking a critical next step: building its first official mobile app. Framasoft, the nonprofit behind the project, has launched a…

  • I found my replacement for LinkedIn!

    If you’ve followed me, you might have noticed that I had pulled back my activities on LinkedIn gradually: I posted less, stopped interacting and deleted my content. But I kept returning – only to feel the same mix of disappointment and annoyance every time. Eventually, I asked myself: Why did I keep coming back –…

  • AI Agents: Loyal Only to the Prompt

    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.…
