This site is curently being worked on. Some parts may be missing or not fully functional. The address of this site has been changed from stefan.gofferje.net to www.gofferje.net. Please update your bookmarks.
As I had a little bit time, I made a new category "IT-stuff" and started posting all my old papers and articles there. It might time take some time until I get everything there and I might not move everything from the old to the new site.
