  The hit of the COVID-19 pandemic has hugely affected higher education in the
world, and as a result, most of the physical classes have been (partially)
replaced by online teaching platforms. This transition is challenging even for
experienced software engineering instructors, as they were pushed to break
their habits and tricks developed over the years. This paper is an experience
report in teaching an undergraduate course (revolving theoretical computer
science topics) for the first time in an online format, and some observations
and ideas of how to engage students during online lectures.
