I am running a small survey to be able to improve the series further this year.

If you have two minutes to spare, please fill out the survey https://goo.gl/forms/nNPzrRpiMERIgtBl2

This week also contains articles that have been published during my vacation since issue 67

Thank you everyone for the support in 2018, this is the last post of the series for this year, the next post will be released on January 14, 2019.

I wish you happy holidays and a great start into 2019.
