Vom Hirn ins Terminal seit 1998
Hi, I'm Stefan Thierolf and this is my web site. I'm an IT
specialist system integration (Fachinformatiker Systemintegration) and work
as Global IT Analyst - Network for a global automotive supplier. I lived in
the United States (New Hampshire) for about five years and moved back to good
old Germany end-of-2018.
I like to blog about Information Technology,
Network, Linux and Security,
therefore most of my blog posts are of "technical" nature.
You can find a bit more information in my about page.
Some photo albums are also online.
In case I forget some web sites I bookmark them ;)
