Thank you for visiting my home page.
I have been working in the IT industry for over 35 years. During that time, I’ve published more than 500 articles, translated two books from English to Norwegian, co-authored two books, and written eight books of my own. Among these are three books about the UNIX operating system and five books about Linux. You will likely find one of these books in your local bookstore.
You can find information about my complete body of work – both articles and books – here.
Keywords here are Open Source (Unix, Linux, development tools) and architectural frameworks.
You will also find information on my other hobbies, like off-grid solutions (solar-based electricity, batteries, solar regulators, inverteres), and exciting pictures from the artistic part of the family.
Please feel free to e-mail or phone me if you have any comments or questions. 
I would love to hear from you.
