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).

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 up LinkedIn, too!
Continue reading How to delete all content from LinkedInI’m running a Synology NAS here at home for a few years now, and I admit: I’m quite happy with it. Even though I haven’t really utilized all of the services. But recently Synology reminded me why I don’t want to buy into one system too deeply.

On Mastodon, I came across Elena Rossini and followed her journey toward greater digital sovereignty. Inspired by her example, I decided to give up my YouTube channel in favor of a self-hosted PeerTube instance.
Continue reading Myown #UnplugTrump to more digital sovereigntyAt the end of last year, we replaced our PCs that were over 10 years old. And with new equipment there is always the question: What to do with the old one?
We haven’t had the best experience of trying to sell old PCs in one go. So throw them away? But … they work quite well! It would be sad to see them just go to the bin. Also, it just felt wrong to throw away fully functional discs, RAM and graphics cards.
So I decided to try a different approach this time. Disassemble the machines and put all the parts up for sale on eBay separately. Not with the aim of making a lot of money, but to avoid electronic waste. – I took pictures of all the parts, gave them a (really) short description and put them up for auction on eBay for €1. The SSDs and HDDs were reset/overwritten and put online with the corresponding SMART values. I didn’t want to cheat anyone who bought a used disc.
If the parts didn’t sell within a few weeks, I could always throw them away. If each item sold for €1, it wouldn’t justify the effort, but at least the parts could stay in use! Maybe someone just wants to try / learn how to assemble PCs. You likely wouldn’t want to buy brand new components for that, right? Who knows (and actually I don’t care).
The Result: after about 3 weeks, to my surprise, almost all the parts were sold! The mainboard and the DVD burner sold for 1€ and 2€ respectively, but all the other parts sold for more.
And I admit: it was also a bit fun to disassemble the machines. 🙂
This week I came across a post recommending the talk from Molly White (@molly0xff) at SXSW, talking about “Digital Sovereignty Is the New Influencer Status“.
The abstract of the talk is: “The real power move for creators is ownership and control of their work and livelihoods. This freedom is actually closer for more people than ever before! Learn from two fediverse futurists how decentralized social media facilitates better publishing, community, and business models. These speakers will cover the theoretical and the practical, including how the landscape is evolving in 2025, where creators should focus their energies, and how they might thrive with or without “walled garden” social platforms.”
It’s an interesting talk, where she’s talking about how (and WHY) she keeps her content mainly on her website and federates it to some social networks for discovery.
Recently I noticed that I hardly ever listen my MP3 music collection – mainly because I don’t like my music players (both on mobile and on the desktop). So, let’s look for a nicer player!
I had only two constraints: 1) it should be able to use the files from OneDrive and 2) it should be able to cache them (in case of no connectivity). And as I went through the candidates, I stumbled across Navidrome:
Navidrome allows you to enjoy your music collection from anywhere, by making it available through a modern Web UI and through a wide range of third-party compatible mobile apps, for both iOS and Android devices.
Navidrome also supports Playlists and Internet-Radio! Nice. So why not let it run on a RaspberryPi at home and make it available through my VPN? But would I have enough RAM left? I just tried!

She linked to an article on her Medium page detailing a catastrophic security failure at Merkur AG. You can find the original Mastodon post here.

This includes payment data, gaming sessions, and copies of the ID cards of over one million players.

We all probably know the drill of a typical workday: back-to-back meetings, side conversations in team chats about some other topics, drafting & scanning emails, creating Jira issues, and juggling multiple project threads. The sheer volume of information coming in such a short time can be challenging.

And it annoys me more and more. It’s often used just asa joke when it’s obvious that a statistics isn’t too easy to interpret – but I see this phrase more and more being used deliberately to produce fake news and to manipulate.
