My subjects of interest


I have been using Linux for more than 20 years. Today I use Linux as my main operating system and run Windows in a VM, mainly for photo editing. Here I write about general Linux topics, useful Linux tools, share scripts, and talk about Artificial Intelligence (AI).


Virtualization under Linux allows me to use photo editing applications that are only available on MacOS or Windows. Therefore in 2012 I installed Windows 7 on a Xen hypervisor. Later in 2015 I switched to  KVM and Windows 10.

I have written some tutorials on “HOW-TO make dual-boot obsolete using VGA passthrough”. These tutorials provide detailed instructions on how to create a Windows virtual machine.

I’m hosting my latest tutorial here. You are welcome to post questions or suggestions related to Windows virtualization on Linux.


I love taking photos, particularly landscape and cityscape photos as well as some street photography. Here you find photos of Israel, Jordan (Petra), Italy and other places I’ve visited. Enjoy.

Over the years I have used some different cameras and systems. This has led me to write about Choosing a Camera System. You’ll also find my opinions about camera gear and first impressions and reviews of cameras I own or owned such as the Nikon D850, Canon R5, and the Nikon Z7-II.

I recently got myself the Nikon Z8 and compared it with the Nikon Z7 II, but from a very practical, task at hand angle.

Green Economy

I care about this world, and I like to leave a better world for my children. For that to happen, things have to change! We have to evolve the way we do business. We need to transform our economy from consumerism into an economy based on services.
