Frequently asked questions

  1. What Content Management System do you use?
    No CMS in that sense, but a wiki engine: Dokuwiki. It doesn't need SQL and there's plenty of plugins to extend what it can do. There are lots of design templates as well, which leads to the question what template I use here: I use Writr, which I however adapted to my needs in some ways. In the last time, I had a few high load situations, which is why I added a Varnish Cache.
  2. I want a RSS feed!
    There are two embedded into the web site (and linked in the navigation): One in German language, one in English. The English one contains less articles than the German.
  3. Is there a full-text search function?
    Yes, there is one in the navigation bar, have fun!
