This page is a hobby project - so don't await continual changes and/or updates.
I try to keep this page at old school style - means simple and not overloaded.

I think this is the reason for what the internet was made
for to share your knowledge and help other people.
Sorry if my English is not perfect but feel free to contact me at

I hope this page is useful for you!

Best regards from Austria/Vienna
