Matthäus is my given name and Wander my surname. If you’re unsure how to pronounce Matthäus, don’t worry: even native German speakers occassionally have trouble with it. Matthäus is the German variant of Matthew, so I’m fine with Matthew or Matt. The ASCII-compatible spelling is Matthaeus (umlaut ‘ä’ becomes ‘ae’).
I’m an author of the German Wikipedia since 2003. I had administrator rights from 2004 to 2011.
- CrypTool 2.
I used to be a core developer of CrypTool 2 from 2009 to 2011.
- Domain Name System.
I have a long-lasting fascination for the Domain Name System, which sparked my first Wikipedia article (2003), a term paper during my University studies (2007), conference talks (e.g. at 29C3 and ICANN 56) and my PhD thesis (2015). I almost took a job at DENIC.
I run my own mailserver for personal emails since around 2002.
