Technical proofer of "OpenCL in Action"

The OpenCL standard is not always easy and the technical proof was a challenge, because the code had to run on different os'es and platforms. But when Matthew Scarpino wrote "Jörn Dinkla is, simply put, the best technical editor I’ve ever worked with" (p. xvii) all the work was worth it.

Haskell and functional programming

It is/was interessting to watch how functional programming went slowly into the mainstream. C++ 11 and Java 8 wouldn't exist without FP. In 1998 i wrote my diploma thesis on geometric algorithms in Haskell (in german).

Reviewer of "Java 8 in Action" and "Introducing Data Science"

I bought the book Java 8 in Action in early access (MEAP) and decided to help as a reviewer. It was a good opportunity for me to learn all the new techniques Java 8 has to offer.

Since my first project in fraud detection in 1999 I am interested in data science. The reviews of the book Introducing Data Science helped my bringing my practical knowledge up to date.
