  1. Debug your DNS traffic with systemd-resolved

    It happens from time to time, that you wonder why DNS is not working, where things are breaking and, especially in case of proprietary software, what DNS requests applications are making. …


  2. Configure DoT on systemd-resolved

    I run own DNS-over-TLS (DoT) and DNS-over-HTTPS (DoH) servers at dns.shivering-isles.com for quite a while now. Finally I made it to configure my Fedora system to use these DNS servers for all DNS queries, not just the ones from the browser. …


  3. CentOS Stream and what the fuzz is about

    For those active in the Linux world, you might heard of CentOS. Long time known “RHEL clone”. There was a bit more to it, but I want to dive into the details here.

And my current projects are some Matrix rooms like “Blogger’s Gathering” or “Git Hosters”. …


  6. Improve your mobile browser experience

    As I just set up my phone’s browser, I thought it might be nice to make some notes and share them with the world. This article aims at people who currently just use their default browser on Android. If you are using the Tor browser or have your own browser best practices, feel free to write and own guide and link it to me on social media. …


  7. Self-sufficient commits

    When I look at commit histories I’m often scared. Scared by what happens if people ever move their source code to another platform to collaborate. A well written git history can help to prevent a lot of reverse engineering of your future self or other developers. How? By providing useful information and explanation about a change. …
