• New website is up!

  I think my first website appeared in 1998. In the succeeding years, I wrote several websites (private and commercial ones) in PHP. My private website was at some point created by the Apache Forrest framework, which generates static HTML output. However, in 2011 or so Apache Forrest was discontinued and I switched to Blogspot.com. After having my website hosted at Blogspot services (now owned by Google) for approximately ten years, I finally decided that I wanted to get rid of their cookies and third-party scripts. For this reason, I now re-built my website with Jekyll after noting that my students used it for years – indeed, I am glad to learn from my students. Jekyll provides essentially the same functionality like Apache Forrest, but better.

• I now have my teaching allowance at FernUniversität in Hagen

  Some personal news: after passing the last defense talk at the Dep. of Mathematics & Computer Science at the University of Hagen in November, I now received the permission to read (venia legendi). This allows (but also requires) me to teach 2hrs/semester (for free!). I wanted to do this because it enables me to share insights from my favorite research domain(s) with more students. Also, this status allows me to advise my own Ph.D. students (as their primary advisor – I already advise Ph.D. students as a secondary advisor since a couple of years).
