As a corollary, if I ever toot anything political, please don't assume that the people whom I follow or who follow me agree with me.

"Point-free" comes from topology, where one does math without mentioning the points of spaces. Did the idea that types are spaces and their inhabitants points exist before HoTT?

If I have:

q : a = b
r : c = d
s : a = c
t : b = d

Can I inhabit q = r?

Nope, I'm still not done with the proof. I don't think I can make a square...? Cubical Agda is so confusing.

I"m almost done with my Agda proof. I just need to figure out how to make a square...

When using Agda, when I create helper functions, do I just call them "lemma," 'lemma2," etc? Those aren't descriptive names, but the real meaning is in the types.

This is so ANNOYING! The propositional equality defined in Agda's standard library is DIFFERENT from the one in the cubical library! And, when the cubical library reproved everything, it swapped the left and right sides in the definition of associativity! Argh!

@hydraz @mdallastella Okay, I went to @epicmorphism's instance and saw the Keionbot, but when I went to its instance, I got an error. I think that the instance shut down?

@keionbot@robo.super-niche.club

@hydraz I remember that you followed the K-On bot and it followed you back. Do you know what happened?

@mdallastella

Nooo! All my boosts of the K-On bot are gone! 😭
