ABOUT ME
Long term Linux guru and author
Long term Linux guru and author
I've been working with UNIX-like systems (Linux, FreeBSD, OpenBSD, Mac OS X and many more) for about 20 years, both as a hobby, as my field of study and as a profession. I run my own company in Sweden in UNIX consultation, education and hosting. I've also written five books about programming and Linux. The first book is about Python. The second book is about C programming in Linux, macOS, BSD and Solaris. The third book is about Linux system administration. The forth one is about Linux system programming (the only one in English). The fifth one is about Docker.
I prefer to do freelance jobs. I can also do sessions though, but keep in mind that I prefer to use text chat only, no voice.

I first started out with Linux way back in 1997 with Slackware Linux. Since then I've gone through many distribution, such as Red Hat, Debian, Ubuntu, SuSE and many more. In 2013 to 2015 I studied for two years to "Linux System Specialist". In 2019 I started writing my book about Linux system administration. It got published at the start of 2020. The book is in Swedish with the title "Linux systemadministration från grunden", with the ISBN 9789198330038
