Teaching about plotting

It was a bit of a rainy day today, though I managed to avoid most of it. I drove Scully to my wife’s work before returning home and then hopping on the train into the university for today’s lecture on Data Engineering. This week we did the topic on data presentation, which was mostly about how to prepare graphs, plots, and other data visualisations so that they are clear, concise, easy to interpret, and not misleading or confusing. It sounds simple enough but that’s enough material to fill a 3-hour lecture and tutorial session. I may have mentioned this in past years, but we conclude with a brief study of COVID data reporting, and examine how the state of Florida in the US deliberately changed the way it reported and presented COVID deaths in 2020 to give the impression that the pandemic situation was improving, when it was actually getting worse.

Before the lecture I stopped in at one of the university’s food outlets for students and tried one of the offerings there for lunch. It was a place that makes Malaysian meals, and I tried the nasi lemak with beef rendang, which is one of my favourite Malaysian dishes. It was pretty good, though not exceptional. The lecturer told me later that he rates the Malaysian place across the road as slightly better.

Back home in the afternoon I made another weekly batch of comics for Irregular Webcomic! and uploaded them to the buffer queue. Then before my evening ethics classes online I had the leftovers from last night’s Indian curry for dinner.

And then into three classes in a row, on this week’s new topic of “Countries”. I got some interesting answers and discussion, and there were some interesting disagreements on the question of whether each cultural group of people should have their own country or not.
