Sieve-Regeln ohne Thunderbird-Plugin anpassen

Vermutlich eher ein “Randgruppenthema”: Sieve ist ein System das eingehende Mails anhand von Filterregeln verarbeiten kann, z.B. automatisch löschen oder automatisiert eine Reply schicken (“Bin im Urlaub”). Wenn das System auf dem Mailserver installiert ist, können die Filter “von Remote” konfiguriert werden. Hierzu nutze ich normalerweise dieses Plugin für Thunderbird, aber Thunderbird hat in seiner Version 102 mal wieder irgendetwas geändert, sodass dieses (und andere) Plugins mal wieder monatelang kaputt sind.

Running Your Own Matrix Homeserver

This is an updated and improved version of an article published in February 2021. Yesterday I played a bit with Synapse, the reference implementation of a Matrix homeserver. Matrix is a federated chat protocol that features end-to-end encryption and does not require a phone number. As the system is federated, everyone can run their own server but can still talk to users registered to other servers. So the situation is quite comparable to email. Read more

Hugo Shortcode für PeerTube

PeerTube ist eine Alternative zu YouTube die ähnlich wie Mastodon das ActivityPub Protokoll spricht. In Hugo können von Haus aus YouTube-Videos per Shortcode eingebettet werden, PeerTube wird nicht unterstützt. Es ist aber sehr einfach die identische Funktion für PeerTube nach zu rüsten: Im Ordner themes/THEME_NAME/shortcodes erzeugt man eine neue Datei mit dem Namen peertube.html. Da hinein packt man folgenden Code: <style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } . Read more

Blogging und Foto-Galerie-Software

(Ein Re-Post mit Aktualisierungen. Hier hatte sich tatsächlich ein unfertiger Bericht ins Rampenlicht gedrückt!) Normalerweise poste ich meine Bilder ja hier im Blog. Das ist recht nett, weil ich noch etwas unter die Bilder schreiben kann. Aber irgendwie ist das auch etwas mühselig obwohl ich ein Script habe, welches mir den Markdown-Code automatisch generiert und auch aus den EXIF-Tags die Ortsinformationen extrahiert. Auch wären zusätzliche Features wie eine Übersichtskarte mit allen Fotos nett oder die Anzeige von EXIF-Daten (Brennweite, Blende, usw. Read more

Automating Default Audio Configurations on a Mac

Usually, tools like WebEx, BBB, Zoom, etc. tend to use the system’s default audio settings. This is nice if you use the same audio devices all the time. But, if you use different audio devices at home, in the office, or when traveling, you have to manually adjust the default audio settings often. (Or worse: you forgot to set the default settings and must adjust the audio settings in the conference tool for each call…) This repeated switching between configurations is annoying and time consuming.

Dockerized HedgeDoc on a Raspberry Pi

HedgeDoc is a Web application that provides a collaborative notepad. Things like an online family notepad to write grocery lists or plan the next trip can be realized. It is pretty easy to self-host this tool on a Raspberry Pi using Docker. Unfortunately, there is no official Docker image for ARM. Instead one has to use the one from or build the image on your own. When testing the linuxserver. Read more

Dockerized Nextcloud on Raspberry Pi

Since 2010, I guess, I run Owncloud and later Nextcloud on different small “servers” in my home network. Recently, I had the impression that my instance, which I updated/upgraded many times, got a bit bloated and some things simply did not work correctly anymore. The other day I decided that it is time to setup up a new instance from scratch. However, this time I did not want to have a complicated native installation running on nginx, php-fpm, mySQL, Redis and whatever dependency my old Nextcloud instance had. Read more

Full Feed For Hugo Blogs

A subscriber of my blog (most probably the only one :D) recently made me aware that it won’t deliver a full RSS feed. I looked into this matter and found this highly helpful Hugo helpfile hidden somewhere in the Hugo the documentation (please note the slight irony). To enable a full RSS feed, do the following: Download the default Hugo RSS feed template and place it in some path/file mentioned here. Read more

Fixing an Update Issue of Command Line Tools on MacOS Catalina

My homebrew had some issues with an outdated version of Command Line Tools (CLT). I tried to update the CLT manually using sudo xcode-select --install but the installer told me, that CLT could not be found on the Apple servers. Strange. I tried uninstalling CLT with sudo rm -rf /Library/Developer/CommandLineTools (this is Apple’s intended way of uninstalling the stuff) and installing it again with sudo xcode-select --install. Same situation. Now I rebooted the machine. Read more
