I'm a tenured lecturer at the Department of Information Systems at the University of Münster, Germany.
In summer term 2017, I created a group for OER at GitLab, as part of which I publish OER presentations, in particular my presentations for a course on Operating Systems (source files).
I maintain and use the free/libre and open sources software (FOSS, FLOSS) bundle emacs-reveal to create such presentations.
Feel free to use, share, adapt.
