@scheminglunatic the reason ghc doesn't let you segfault by casting along bottom is that it actually reduces proofs before doing a cast. so if you try to coerce along fix id you get stuck first evaluating fix id. this is unlike e.g. idris where you can substitute along an @0 identity.

afaict unsoundness by nontermination in haskell's type system when you fw the higher typelevel extensions doesnt mean you get runtime bugs due to explosion it just means the typechecker might run forever and overflow the stack but only at compile time. but u won't get type errors at runtime.

"muh halting problem" (or sometimes "muh rice's theorem") is probably one of the worst thought-terminating cliches ive had to deal with when describing the value prop of formal methods, richer type systems, etc. to others.
"but, what about halting tho?"
lord have mercy.
Rob Miles@robertskmiles
Again: The Halting Problem DOES NOT say that it's impossible to ever know whether a program halts! There's no way to *always* know whether an *arbitrary* program halts. But there are infinite programs that provably halt or provably don't. In practice static analysis is useful!

You obviously stand to make money by pinching your book as wildly "more practical" than the rest.

Listening to graninas will never be a worthy industry practice. 🚷
His takes become obsolete much faster than he can actually post them. 🚮
His so-called "books" are just a questionable tactic to squeeze money out of the industry.🧑🔧🔫🕵️
You know why. ⬇️

@sarah_zrf @grassmannian I'm sorry that neither of you can read changelogs 🥲 I know they're very complex pieces of technical writing but I hope you'll recover soon 🙏

For each natural number n, let Gₙ be the number of isomorphism classes of (simple, undirected) graphs with n vertices.
Does
∑_{n=2}^∞ 1/log(Gₙ)
converge?

@evanewashington I flipped through her book x+y. the point of departure is eschewing "set theoretic" approaches to gender in favor of a "categorical" one.
It seems like to justify her approach she had to throw set theory under the bus by associating it with political tribalism and transphobia.

are other popular audience books as bad as the ones in the philosophy section or am i just biased

@EscardoMartin @carloangiuli This is 100% an implementation bug. Rewrite rules are already not allowed to participate in explicit mutual recursion.

This is one of the funniest proof assistant bugs I've ever seen... It's so easy for features to interact in unexpected ways! (h/t @plt_amy) github.com/agda/agda/issu…

removing wisdom teeth. wisdom teeth are healthy organs but it's normal to remove them even in cases where all they are doing is causing discomfort
Tripwire@Ravie777
@halomancer1 @TheAtlantic @helenlewis What other "healthcare" cuts off healthy organs? You're sterilizing and removing body parts from kids to treat a mental health condition. Why should it be taboo to say that it's extreme?

@lightediand @matthematician these generalise smooth algebras, which, honestly, why aren't they called real smooth algeb-- i mean, have operations for each *smooth* map RR^n→RR instead. and aiui these are actually seriously studied by a number of people with more than a single digit
English
@lightediand @matthematician once that has stopped feeling wonky you'll see some truly funky objects people study:
at a seminar a week or two ago i attended a lecture on "real-continuous algebras" — extremely nonstandard name — which have operations corresponding to every single continuous function RR^n→RR

@cirkelnio turns out [incredibly heavy sigh] there is config to control this (ui.popup.disable_autohide), which was set for a reason i do not remember, and troubleshooting mode does not disable your preferences. i guess if the trouble you're shooting is config-related you can get fucked
English
I have no idea how to search for this but has anyone else encountered this bizzare issue where firefox ui popups on macOS just. get stuck there. and you can't click away from them. this is troubleshooting mode so definitely not an extension
