I'm interested in

• Mining in the Upper Harz between Wildemann and Clausthal-Zellerfeld (16th to the 19th centuries)
• Information security

• Military today and in future
• Czech Republic, Hungary und die Slovakia

Mostly, I write articles on the German Wikipedia and I maintain several German Wikibooks. Furthermore, I upload images from time to time.
