There are always some ideas floating around in my head of things that I want to write. Some fade away, and others I capture in my GTD system. And on some rare occasions, I invest the time to move my thoughts from my brain into a nice blog post.

If you’re asking about what I write: I really can’t tell. Most things you can find here at the moment are about Linux, coding, and similar stuff. But I won’t promise that this won’t change. We’ll see.

Disabling comments


Update 03. April 2018: I re-enabled comments with an anti-spam plugin. If it works, I’ll keep them enabled, otherwise I’ll disable them again. I’m running this WordPress instance since August 2017 now and at the end of last year my page was finally listed on one of those unreachable lists of WordPress pages, where some friendly bots can write awesome comments about my writing style or try to sell me some nice medicines of the highest quality for the best prices.

Moving the open-source stuff from phab.mmmk2410 to GitLab


The journey started in early 2016 when I decided to move my open-source projects and their management away from GitHub. First I launched a cgit instance for viewing the code and set up a gitolite for repository hosting. After a short time I moved the repositories to a self-hosted Phabricator instance at, because with that platform I had the possibilities for project management like issues or workboards. But this concept also didn’t last for long.

Cavallino-Treporti (IT) Bicycle Tour 1


During my holiday in Cavallino-Treport (IT) I discovered the following bicycle track. The tour starts at the Piazzetta della Libertà in Cavallino and goes from there over the Via Francesco Baracca to an first unpaved way and later on Asphalt next to the Fiume Sile to Jesolo, where the river will be crossed. From there the track goes over a cycle path to Lido di Jesolo where the way leads through the inner city.

Tja, wenn der Tag schon gut startet, was soll man dann erwarten. Nachdem ich auf dem Weg zur Uni nicht mit dem Rad gestürzt bin und der Aufbauf zeitlich sehr gut lief (auf den halbjährlichen Belastungstest der elektrischen Anlage der Universität durften wir dieses Mal verzichten). Doch wenn schon so vieles gut läuft, dann muss ja irgendwann der Rückschlag auf einen zukommen. Heute kam dieser beim Einschalten meines Computers. Strom, Monitor, Tastatur, Maus und Ethernet waren schon verbunden, von dem her sollte ja eine einfache Betätigung des Einschalters vollend genügen.

Der Drucker


Wie schwer kann es sein, Altklausuren auszudrucken? Da ich mich, warum auch immer, dazu entschieden habe, Informatik zu studieren und nicht Chemie oder anderes, habe ich das Glück, ein dafür entwickeltes Werkzeug verwenden zu können (bei anderen Fachschaften verwendet man ein Wiki zum Speichern von Altklausuren). Somit beschränkt sich die Arbeit hauptsächlich darauf, schlecht formatierte E-Mails zu entziffern, Vorlesungsnamen in das Programm einzugeben, die letzten paar Altklausuren auszuwählen, den frisch gedruckten Stapel Altpapier zu beschriften und die Leute darüber zu benachrichtigen.

Rangitaki Version 1.4.4


Today I announce 1.4.4 of the Rangitaki blogging engine. It brings an important bug fix concerning the feed creation. Starting from 1.4.0 the feed creation server-side script failed with a 500 internal server error because it was not converted to the new YAML configuration (due to a bug - to be exact: a missing slash - in the .gitignore). While working on fixing this issue, I also upgraded to the latest version of the feed generator (PicoFeed).
