Welcome @stoeps.de, the blog of Christoph Stoettner
I work at Vegard IT GmbH as a senior consultant with a focus on collaboration software, Kubernetes, security and automation. I mainly deal with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform and Linux.
Sometimes my daily work results in technical talks and blog articles, which you can follow here more or less regularly. You can find the presentations in the main menu under public speaking .
I created a list of tools I use regularly, most of which have been released under an open source license.
In my spare time I read a lot, test all kinds of technical software and gadgets and try to follow about 200 RSS feeds.
Here you can find a collection of them.
This is my private blog, all opinions are my own.

Mid 2018 I switched my blog from Wordpress to Hugo . Main reason was performance and that I can use Asciidoctor to write the posts.
What happened the last 18 months? I stayed with the theme I selected 2018, but I tweaked it a little bit. So I added lunr to implement searching, changed all scripts and fonts from CDN to local (privacy and tracking), updated Bootstrap 3 to 4.
Working with Bootstrap was quite fun, I haven’t done a lot of HTML or CSS the last years, but the grid and css classes from Bootstrap are working without checking each change on all browsers and are responsive.

In my spare time I like doing CTF (Capture the flag) or solving machines posted at Vulnhub . This time I started Christmas vacation with Me and My Girlfriend: 1 .
Extracting and importing into Vmware Workstation was straight forward, after the start we need to find the ip address of the vulnerable machine.

For GPN19 I prepared a second talk on Documentation with any Editor . The talk was based on a previous one from Froscon 13, but the pipeline tooling changed.
This time there was a technical issue during the recording and so there are only the slides available, but you can still watch the video of the Froscon talk: Froscon 13: Documentation with any Editor
