a cosmological pedestrian
Two years ago, I started to look into writing a tree-sitter parser as part of the “Day of Learning” at my employer. As I write and edit many RPM Spec files (also at work), I wanted better highlighting in my text editor, which is Neovim. I had attempted to start the project the year before but was lost. The next year, the tree-sitter documentation improved,...
I am thrilled to announce the release of cmocka 2.0, a milestone for the cmocka project. cmocka is a unit testing framework for C, designed to be simple, portable, and easy to use. It provides a straightforward API for writing and running tests, making it an excellent choice for developers who need to ensure the reliability and correctness of their C code. A Brief History...
I own a Prusa Core One. Lately I had to print several things for my car (Camper Van) in ASA. If you wonder about the reason, it is ASA is heat resistant and temperatures can go quite high in a car. ASA is really hard to print successfully. The reason is that it retracts when it cools. If you have an enclosed printer, you normally...
My workstations and notebooks normally are in English which is not my native language. For currency etc. I have set it to de_DE. However the date I want in ISO8601 24h format. However this is not supported by default. Here is how to get it: First you need to install the glibc locale source package. Now we need to create a complete new locale, even...
by Alexander Bokovoy and Andreas Schneider FOSDEM 2025 is just behind us and it was a great event as always. Alexander and I had a chance to talkabout the local authentication hub project. Our FOSDEM talk was “localkdc – a general local authentication hub”. You can watch it and come back here for more details. But before going into details, let us provide a bit...
KDE had a feature a lot of people didn’t know about. You could run a command when a notification triggered. The feature wasn’t very well documented and nobody really blogged about it. However with the release of KDE Plasma 6, the feature was removed. I learned about it by accident, as it is tracked by Bug #481069. I really need the feature and I re-implemented...
At the beginning of December 2023 gdb version 14.1 was released. The feature I’ve waited for is support for the the Debug Adapter Protocol. Today I finally looked into this and got gdb working with nvim-dap. If you already have setup nvim-dap, it is pretty easy to add support for C/C++ with gdb. First you need to enable DAP for the filetype. I load DAP...

The git versioning system has two really nice features you might already heard about. One of them is git-worktree and the other are bare git repositories. This makes my life a lot easier working on Samba as often I have several feature branches I’m working on. Some features often take several months to finish. I don’t want to compile them again and again every time...
To the newcomer, Samba’s command line user interface appears to be a haphazard jumble of scripts and binaries with options and design principles that fade in and out of use according to some esoteric pattern. Douglas Bagnall The initial quote is from the SambaXP talk What should we do with our user interface? in 2019. Douglas wrote that nobody can fix it as experts are...

I’ve recently bought a Garmin Fenix Multisport Smartwatch. The watch offers support for navigation and maps. By default it came with some topo maps for Europe. However I wanted to use more detailed maps from OpenStreetMap. After some search I’ve discovered the wonderful Freizeitkarte project, which is a project to offer maps for Garmin devices. The default maps work OKish on the device. However as...
