When physicists promote Quantum Key Distribution (#QKD) systems, they tend to claim things like: “it is unbreakable because of the laws of quantum physics”

The @bsi has a great report on why that's not true, and that these systems are also vulnerable to many possible implementation attacks.

Adding content to my knowledge base

I wrote about it a while back but meanwhile some tools no longer exist and I stopped using some others. This post describes my current setup as well as my plans for the next evolution. The intention and generic workflow remains unchanged but some tools have changed Once Omnivore disappeared I switched to Readwise reader for collection. When Logseq announced to move to a database version I had doubts how portable and tool independent it might be Independent of Logseq I decided to switch back to Emacs. Part of that switch away from VS Code is that I no longer use the Dendron software but I keep following its hierarchical note-taking format since it works well for me. On mobile I use native graphical Emacs but also the mobile Obsidian client which supports more “standard” markdown. The nice Dendron Tree plugin makes Obsidian feel like Dendron. I also consume PDF and EPUB documents in Moon+ Reader for Android and the tolino epos 3 e-book reader. calibre is my tool for e-book management. Changes to my workflow Capture I tend to collect lots of links to interesting articles, PDF and EPUB files and I regularly buy e-books.

#til For quite some time I wanted #pyhon code folding in #emacs and even tried several packages but none of them worked as I expected it.

Now I realized that the built-in hideshow mode does exactly what I want.

Another example that the answer to "can Emacs do that" is always "yes" and very often even has it built-in. Amazing!

Heute ist Dienstag der 24. Februar 2026.

Vor 410 Jahren, am 24. Februar 1616, verurteilte die Inquisition Galileo Galilei zum ersten Mal wegen der Häresie dass sich die Erde um die Sonne dreht und die Sonne stationär im Zentrum des Planetensystems befindet.

Zugleich ist heute der 44. Gründungstag einer Computerfirma, die es nicht mehr gibt.

Sie hieß SUN.

Der 24-Feb 1982 war ein Mittwoch. Mittwoch ist ist also SUN-Day.

Using plain text files

This post is in response to Ellane’s invitation to answer eight questions about using plain text files. When did you start using plain text? During my time at university when I started using LaTeX to write my Phd thesis. Why did you start using plain text? Writing math in anything but TeX/LaTeX is a pain and in doing it I started to appreciate distinguishing between content and formatting for an end result.

Manage JDex with Emacs

A few years ago I came across the Johnny.Decimal system to organise your life and I find it really useful to organise stuff at work. An important part of the concept is the index or JDex. Johnny recommends storing it in a notes app and has examples for Bear and Obsidian. I prefer Emacs and Orgmode. Of course Emacs makes it easy to streamline the workflow. This post describes my configuration and workflow.
