2021 Book List

In 2021 I read 20 books. Some of them were good and some bad. Out of these books only two stuck with me: Ilium by Dan Simmons and Flowers for Algernon by Daniel Keyes.

Ilium is a must read for every fantasy and/or science fiction fan. It does not attract by a catchy story or using smart concept. The sheer unlimited creativeness gets one hooked on the book. Currently I am finishing the second book and it has been on of the largest I read in a while.

Flowers for Algernon is my definition of literature. Daniel writes about intelligence in a way that makes it much more understanding and compelling.

And here is the full 2021 book list:

I am using Obisidan to manage markdown files and Vuepress to publish them. With the help of a script build.js the Obsidian vault is converted into a publishable format for Vuepress. Obsidian supports embeding markdown files using the ![](file.md) syntax. Here I’ll show you how this feature can be enabled for Vuepress.

Weder Freiheit noch Trychler

Für einmal wird es politisch auf meinem Tech-Blog. Es geht um die Freiheitstrychler. Das ist eine scheinbar harmlose Gruppierung von radikalisierten Massnahmengegnern - sie sind mir seit deren Gründung ein Dorn im Auge. Wer das aus der Zukunft liest: Kontext ist die Corona-Pandemie, die zu diesem Zeitpunkt in der Schweiz leider nicht überwunden ist.

Ansible: Combine group and host vars

In Ansible the configuration parameters are usually separated into two categories: host and group vars. As their names say these are variables that are either applied to a specific host or a group of hosts. And here is already an edge case. What if we want to configure a variable for group, but then also give the possibility to modify for a specific host. Read on to see my solution.
