Build and deploy Odoo with and without Jenkins

Jenkins is a popular but outdated CI/CD system. Compared to modern CI/CD systems such as GitHub Actions or GitLab Workflows, Jenkins does not deliver on containerization. As Docker containers are high in demand for building and hosting applications Jenkins has to go some extra miles. Nonetheless, Jenkins is yet the only self-hostable feature-rich CI/CD solution. For a project I went with Jenkins to deploy a multi-stage Odoo environment.

In this post I would like to present the main parts of the final project such as the Docker setup or the Jenkins pipeline. An important goal was that the deployment can be done without Jenkins.


Don't overdo it

Being employed to think and to care can become a quite burden over time. I thought about “stress” a lot and would like to share my learnings:

2023 Book List

In 2023 I read 17 books. Most of them were great, it was difficult to choose my favorites. As most of them were science fiction books, I chose a non-fiction and a fiction book. My favorite fiction book was The Futurological Congress by Stanislaw Lem and the non-fiction book is Corruptible by Brian Klaas.

And here is the full 2022 book list:


Noise Cancelling

Do you remember clickbaiting? In the two millennia, this was a vicious way to attract attention. The practice was simple: assign an exciting teaser to a boring article. That will get people excited and increase engagement. What was criticized by quality journalism then is the standard today.


Convert Obsidian canvas to SVG

I am using Obsidian for note taking and writing documentation. With Canvas-Feature you can create simple visualizations and link notes from the vault. Here is an example:

As simple as it seems, there was not builtin-way to export the visualization and f.g. publish it on a website. Luckily, the canvas file is a simple JSON document and therefore can be processed pretty easy. I build a render Method in JavaScript that takes the canvas content and returns it as a SVG image.


Hide native tabs with Tree Style tabs for Firefox

As the workspace for developers has moved almost entirely into the browser, browser extensions have become an integral part for customizing the workflow. Recently, I started to the use the Tree Style addons: https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/

When using this extension, the native tab bar becomes obsolete. The following part of the post is an instruction on how to hide the native tab bar (which is a bit difficult).


Future Words

I feel very uncertain about the near future. Climate change, migration, pandemics, rise of populism, oligopolistic capitalism i, post-fact, artificial intelligence, the list goes on. It is a lot to think about and to make sense of. However, I try to embrace what comes and avoid doom and gloom. Making up new words is one way into the future.


2022 Book List

In 2022 I read 18 books. Some of them were good and some bad. Out of these books only two stuck with me: There Is No Antimemetics Division by qntm and Undinge by Byung-Chul Han.

There Is No Antimemetics Division deals with the idea of antimemes, which is the opposite of a meme or to put it plainly is non-information. qntm is a prolific writer for the scp wiki. Scp is a database of fictional anomalous objects, entities, and phenomena. The idea of antimemes is very strange and difficult to grasp, however, qntm built a very engaing story with this subject.

Undinge is an exploration of paradigm shifts of things becoming “smart” things. Han is a contemporary philosopher and in this book he skilfully describes the problem of objects that suddenly produce data and dictate to us as humans.

And here is the full 2022 book list:



Die E-ID ist ein staatlich anerkannter Identifikationsnachweis. Alle Informationen zur E-ID werden unter http://eid.ch publiziert. Ich verfolge das Projekt nur am Rande, bin am Thema aber sehr interessiert. Kryptographie, Politik und Wirtschaft treffen hier aufeinander.

Bei AdNovum war ich als Identity und Access Management (IAM) Integrator angestellt. Dabei habe ich viel über Zertifikate, Infrastruktur, Kryptographie und Systemtechnik im Allgemeinen gelernt. Mit diesem Wissen habe versucht eine E-ID zu skizzieren. Die folgende Grafik zeigt wie eine E-ID konzeptionell funktionieren könnte:


Abrupt Decay

I am an (addicted) Magic: The Gathering player. I love the game, its complexity, the story and of course its art. The card in the header image is Abrupt Decay. Inspired by its caption and artwork I wrote a short poem about decay and regress:
