@jeanas I know type theory but nothing about cubical. I'd wager the article could use some pointers to the mathematical "underlying" objects one is manipulating? Like, I tried cubical Agda and did some equality casts that I could do syntactically because it's just type theory; but the tutorial kept mentioning fancy words and saying I constructed some topological transform(ation)s (?) or something and it just went right past me.
Is there some Wikipedia-ready summary of what is an interval, and how they are used to prove e.g. FunExt?
Anyways that's what I'd hope to learn from the article, do with that what you will. I look forward to reading a competed article some time in the future 💪

@jaseg@chaos.social Reminds me of this blog post, except they don't have fans: https://austinsnerdythings.com/2025/11/24/worlds-most-stable-raspberry-pi-81-better-ntp-with-thermal-management/

@dnkboston > But do you know what's already happening in the name of getting the Rare Earth Elements needed for solar?
I can imagine but probably you have some more resources for me to read up on it?
The state of balcony solar in Zurich 🇨🇭 (2025 colorized)
I hate it when this happens in my #rocq proofs...
@fragdenstaat@chaos.social Habt ihr solche Dark Patterns wirklich notwendig?
Zulip's little timezone aware time widget is one of the greatest advances in texting of the last few years.
@skewray@mathstodon.xyz I think they do, don't they? The black one 🖤 i'd only use when grieving for someone; and it seems that there are meanings to the others some of the colors as well but probably it's very situational.
I don't know the difference in meaning between all the differently colored heart emojis

and at this point I am too afraid to ask (except on mastodon)

@taschenorakel@mastodon.green @crabby@mastodon.world @artcafe@troet.cafe @hllizi@hespere.de @musevg@23.social @chrisstoecker@mastodon.social Nein. Sein Handeln als Minister (damals) verantwortet er nicht vor den Bürgern seines Wahlkreises, sondern vor uns allen. Er eher vor niemandem, denn als Minister wird man nicht gewählt, sondern ernannt.

@olynch@mathstodon.xyz sadly this does not work on mobile--do you have a PDF export or recording somewhere?
