  1. Fujifilm Filmsimulationen als Darktable-Stile, Version 1.1 (2026-01-04)

    Eine neue Version von den Darktable-Stilen, die ich vorgestern veröffentlicht habe, zur Behebung von zwei kleinen Fehlern.

  2. Fujifilm Filmsimulationen als Darktable-Stile (2026-01-02)

    Ich habe Stile für Darktable gemacht, welche sehr nah an den Fujifilm Filmsimulationen dran sind, die man von den Kameras der X-Serie kennt.

  3. ROCKPro64 as Multimedia System and NAS: A long journey (2022-09-26)

    The ROCKPro64 by PINE64 is a single-board computer based on the RK3399 system-on-chip. It features a powerful ARM hexacore and lots of useful peripherials, including a PCIe x4 slot. This article describes my journey of converting it into a home multimedia system and network attached storage device, based on Debian.

  4. Designing an Infrared Forwarder/Sniffer/Injector Microcontroller Firmware (2022-02-26)

    After I decided that rolling my own piece of magic hardware was the only way forward, this post details how the firmware for my ATtiny2313a-based infrared sniffer/forwarder/injector was designed and implemented.

  5. Remotely controlling a Denon AVR-1910 from Linux (2022-02-26)

    I have a, by modern standards, ancient Denon AVR-1910 audio/video receiver. Now that it lives in a nice cabinet without line-of-sight, I want to make it more remote controllable. HDMI-CEC is not an option (see inline), so obviously the only way is to inject Infrared commands.

  6. Making the Isolation bearable: Self-hosted Audio/Video Conferencing with Jitsi Meet and Mumble (2020-03-21)

    The global COVID-19 pandemic is a serious issue and governments as well as individuals are taking action to reduce the physical social interaction between humans in order to limit the spread of the disease. This has been taking a toll on shared A/V conferencing infrastructure and some may want to not rely on third-party offerings for privacy reasons. Nowadays, it is not too hard to set up your own A/V conference server—with Jitsi Meet. Aside from providing a few tips on the setup, this post also has detailed measurements of a multi-hour six participant Jitsi Meet session.

  7. On Centralisation of Code Hosting Infrastructure—An Argument (2019-07-08)

    Last year, we’ve seen GitHub getting bought by Microsoft. This event has caused the FLOSS community to run in circles panicingly, because Oh My God Microsoft. There was a certain exodus from GitHub to GitLab (who played the event masterfully, PR-wise). In that context, folks were (and still are) discussing the issue of centralisation of development infrastructure in the FLOSS communities. Here’s my argument.

  8. Stable vs. Rolling Release—An Argument (2018-12-03)

    I often get into arguments because of my strongly-opinioned choice to use a "stable" Linux distribution (Debian). Since those arguments often take place via Instant Messaging, I came to the conclusion that I have to write my view of the argument down to avoid misunderstandings.
