Three years ago was my last day at Hewlett Packard Enterprise, and now my time at the university is coming to a close, too.
Two years ago, there were no signs of all the changes the pandemic would bring.
A year ago, we were already fighting with the pandemic, and I was already doing regular walks with my buddy Machop.
Today, I will go on another walk with him.
But, I am still as excited as I was three years ago, and I can’t wait to see what the future holds!

One of my upcoming New Year’s resolutions is to run regular meetups in my home town, Cologne.
To do this, I’ve started a new meetup group on Rancher in Cologne, my most favorite open source tool for compute in Enterprise IT.
The Group is called Rancher Meetup Cologne, and I’ve scheduled our first meeting for January 14th, on all what’s new in Rancher 2.3.
Hope to see you there!
During the winter developer’s conference at Senacor Technologies AG in Nuremberg, they presented a nice little tool to measure and offset carbon dioxide emissions during business travel.
The tool is called Vagabundo and is realized using a serverless framework; it collects data from all business travels, calculates CO2 emissions and offsets them through Atmosfair – great approach at using technology to protect our climate!
It’s currently an in-house project, but Senacor seemed amiable to open-source it.
Much more than the offsetting part, I like the reporting – how much CO2 do I emit during travel and how could I optimize it?
Taking this a step further, I could see creating internal (team) competitions – who’s the best at having video conferences instead of in-person meetings? Who’s able to reduce air travel the most?
I think, there’re endless possibilities – anybody as interested as I am?
As part of a school machine learning project I stumbled upon the excellent tutorial by Elite Data Science on Scikit and wine quality.
This tutorial uses a data set on wine quality for training and testing provided by the University of Massachusetts, Amherst.
As we’re nearing the end of life on Python 2.x, I’ve updated the tutorial script to work with Python 3.5.3 (on Debian 9).
Great starting point to work with new data – I can highly recommend the tutorial!
After a brief stint at a small consultancy in Cologne I decided to go back to working as a freelance IT architect and consultant, with my favorite open source cloud projects, Rancher and Kubernetes, and everything else cloud native. I have also submitted a couple of papers to regional conferences.
From August onwards I’ll then have two more years at University, and during that time I’ll need to figure out whether I should be starting my own business, continue going solo, or try to find full-time employment again. Main goal: Get my kids through college. And enjoy my work.
On that note: I’ve passed all exams so far and am happy with the results!
From time to time it does make sense to clean your computer systems, literally speaking.
Especially if you run them in a domestic or office setting, any system with a fan will collect dust. A lot of dust.
Nothing a can of pressurized air, a hoover and a set of baby wipes can’t fix though .
Did anyone say weekend?
Being a long-time Linux user and ardent fan of Debian GNU/Linux, I find myself more and more in a situation where I favor a BSD-style Unix over Linux.
My first real contact with FreeBSD was through the now sadly defunct Debian GNU/kfreebsd distribution, the next logical step was to set up a FreeBSD workstation (with KDE) and now there’s no turning back. One of the main benefits of using Linux over Windows was always to have fine granular control of all the processes and steps – systemd is way too much Windows-like for my taste. Nothing against Windows – I do all my daily office work on Microsoft Windows and Office, but on my servers and workstations I want a shell prompt and full control.
I still run Debian on my GCP cloud servers, for my next server at home I’ve settled on FreeBSD though.
I did have a look at the possibility to replace systemd with SysV-init on Debian, I also looked at Devuan, but in the end the simplicity and elegance of FreeBSD won me over.
Today is a slow day – Friday after a bank holiday (Ascension), which most people here take off from work (including myself).
Time to appreciate my inbox. My empty inbox, that is.
Ever since I came across Inbox Zero, I tried to stick to it, most of the time. According to its inventor, Merlin Mann, it’s not so much about reducing the number of Emails in your inbox, but about reducing the time you’re thinking about the things in your inbox. From personal experience over many years of working I can fully and wholeheartedly agree – an empty inbox makes your day much less stressful!
I’ve settled on Outlook, Tasks, and OneNote to manage my work, but it’s not the tooling that makes the difference, it’s the mindset.
Give it a try – you won’t regret it!

This week we had a Rancher User Meetup in Cologne, and Jan Bruder of Rancher introduced us to the new features in 2.2:
- Built-in cluster and application monitoring
- Global DNS
- Multi-tenant catalogs
- Backup and Restore for Kubernetes configuration (etcd)
- Bitbucket support for pipelines
It was a great session and many thanks to Jan (and Rancher) for coming!

A year ago today was my last day at Hewlett Packard Enterprise. As part of the many reorganizations, HPE were offering very generous redundancy packages at that time and I decided to take them up on their offer and go back to University (FOM), to study Computer Science in Cologne.
I’m now at the end of the first year, and I’m absolutely loving it! It’s such an enormous privilege to be able to concentrate just on learning, given my age and the fact that I have two (almost grown-up) kids.
To stay on top of all the developments around cloud computing I also work part-time at a small Cloud Consultancy, supporting customers on their journey to cloud; by now I’ve become pretty experienced on all things related to Containers and Security too. Serverless will be next!
In the process I’ve also lost over 40lbs – can’t complain! There’re still a couple of pounds to go, though …
