This was supposed to go up last week, but I forgot. So have it this week instead!

  • Killer kangaroos? That’s what happened when programmers tried to reuse a bit of code in a simulation for the Australian armed forces. (Reported on Thomas B√§tzler’s website.)
  • Harry Enten of FiveThirtyEight contends that while gerrymandering is certainly a problem, it isn’t the main cause of American political polarization. People are moving to regions where people share their political views, and people are having their political views shaped by their neighbours, independent of districting.
  • Author Melissa Caruso has a neat Twitter thread explaining the feasibility of dress combat. Surprise! In some cases, it’s not only feasible, but it can even be practical.

Finally, a couple of videos, because why not?

  • MatPat of The Game Theorists explains the problem with YouTube’s recommendation algorithms: videos that get embedded on trusted external websites (e.g. CNN, Variety, ABC) get boosted, which means that if a controversial video generated a lot of news stories, it actually stands a higher chance of trending. This is exactly what happened with disgraced YouTuber Logan Paul’s Aokigahara video.

That’s all for now. Ciao.
