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.

Additionally to the social accounts, you can reach me on matrix with @stoeps:matrix.org or join my matrix channel #stoeps:matrix.org . For the moment contact me for an invitation to the channel, I need to figure out how many spam accounts will join, if I set it to public.

I save links I want to read later or store because they are interesting in Shaarli .

Shaarli delivers a nice overview of links on daily , weekly and monthly basis. Or you check the Tag cloud when you’re interested in special topics.

I try to add some description to each link, so I don’t need to create the linkdump posts.

Why is the domain name stoeps?

This is a very old story and it started in school. Stoeps was just my nickname and I have kept it ever since.

During a migration from Cognos Metrics to Elasticsearch Metrics, I had some issues with the index. So I wanted to create a backup of the already migrated data and start over from scratch.

The official documentation has an article on the topic: Backing up and restoring data for Elasticsearch-based components , but I had to slightly adjust the commands to get a successful snapshot.

The last years I had issues with application servers using large amount of CPU and even hanging application servers running the Tiny Spellchecking service. It ended with disabled spellchecking in the Tiny editors config.js.

I created a git repository with some smaller CSS files to fix some annoyances within HCL Connections.

I started with this to prevent Orient Me to load fonts from external URLs or Elasticsearch Metrics to break the UI on larger screens. These issues are solved after the last updates I got from support, but Blogs and Tailored Experience Wizard can be improved with some simple rules.

After rebooting the Kubernetes server for HCL Connections Componentpack, I sometimes see that Orient Me is not working and just shows:

CVE-2021-44228 was a very serious problem end of 2021, and we are still finding new occurrences, or security teams scan servers and find vulnerable log4j files. Don’t get me wrong most of these occurrences are not vulnerable any more, because the JVM is hardened like in the Elasticsearch 7 containers, or they use of the JVM parameter -Dlog4j2.formatMsgNoLookups=true.
