My subjects of interest


I have been using Linux for more than 20 years. Around 2000 I switched permanently to Linux, dual-booting into Microsoft Windows when necessary. So far Linux has been good to me. I cannot recall ever catching a virus or other malware, or facing an unrecoverable system crash. There has always been a way to recover my personal data.


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. Don’t forget to register!


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.

You’ll also find my own opinions about camera gear and some first impressions of the Nikon D850.

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.
