Combining Venn diagrams with pie charts works pretty well.

I shall write replies on the internet, just as my ancestors, whenever someone is wrong about something. And one day, I hope to stumble upon an online utterance from the far past of my lineage, which is wrong, so that I may finally correct them. And so too shall my progeny.

Some movies are best seen in theaters, while some are best seen at home with friends. And some are best seen on sketchy live-streaming sites, with a chat making comments and spamming emotes.

Lean doesn't really "synthesize placeholders", unless you're talking about instance search which I think just picks the first solution found that works.

Electronic music producers, you may be making a banger, but there's no need to include beeps as if a bomb is about to explode.

In orders, one talks about top (⊀) and bottom (βŠ₯) elements, but bottom is too long so one instead calls them top and bot. But bot means many other things. Why not call them bottom and toppom?

Pointwise Definable Models of Set Theory A pointwise definable model is one in which every object is definable without parameters. In a model of set theory, this property strengthens V=HOD, but is not first-order expressible. Nevertheless, i...

For a rigorous exploration of this argument, one can read "Pointwise Definable Models of Set Theory" by @joeldavidhamkins.bsky.social et al. For example, they show that there are models of ZFC where every real number is uniquely definable.

There are too many linux distributions. Maybe it's time to sacrifice some of them, to usher in the year of the linux desktop.

Sometimes people online write "I don't know why, but X reminds me of Y", even when it's obvious why X would remind them of Y (e.g. two similar songs).

Has anyone else noticed this pattern? Why would someone write that?

You might think that "I'm Thinking of Ending Things" and "Sometimes I Think About Dying" are the same movie, but they are actually very different; the latter is a Star Wars movie.

Wikipedia sometimes allows non-free SVGs, but only if they are small. If you zoom in on an SVG, Wikipedia will go to jail.

Complimenting someone's gait feels uncouth, as gait is a pretty ugly word. Maybe I should say that I can see positive qualities by the way they use their walk, no time to talk.
