Grüezi and welcome! My name is Claudio Kuenzler and I'm a Senior Systems and Site Reliability Engineer (SRE) working in the Zurich area in Switzerland.
The year was 2005 - that's when I started working with Linux and open source software/systems (professionally). Dang, that's 19 years working on the command line already! Prior to joining the Linux and Unix world I was a web application developer (back then it was called Web Publisher) mainly coding in PHP. In all these years I came across a lot of technical challenges. This blog documents how I tackled some of them. The idea is to not keep every solution in mind but rather use the blog as an archive and reminder to myself if I come across the same problem again. Yep, that has already happened a couple of times. TL;DR: This blog is foremost my own personal reminder how to solve a challenge. Use the content if you like it, but there's no warranty on the information.
In my spare time I like to spend time with my family and friends, travel and (try to) play tennis. Although I spend so much time working with computers and technology, I'm (still) curious and fascinated by it and tinker on some projects.
You can find me on Twitter, GitHub and LinkedIn.
I am available as off- or on-site open source systems consultant; mainly for monitoring (Icinga 2, monitoring architectures, dedicated monitoring solutions), systems security (PCI-DSS certified architectures using 100% open source software), automation (Ansible), container technologies (LXC, Docker and Kubernetes managed by Rancher 1.x and 2.x) and in general systems or application troubleshooting on Linux systems. For more information regarding consulting please check out the consulting page at Infiniroot.
Now I sincerely hope you enjoy this blog. Feedback is always welcome (and keeps me motivated to continue this blog)!
