wait, full semi-trucks!? i don’t think they would even fit into most european city streets at all. especially not American style semis, with the long nose, rather than the european semis which have a completely flat front

this is the original picture

the original picture of Mitch sitting in the hospital bed. The text on the shirt of the baseball player in the newspaper is accurate and the title actually ends with S as in SPORTS.

this meme reminds me of this very helpful, well translated, text in the first boss fight of FFVII

Screenshots from boss fight against a robot scorpion in Final Fantasy 7. The tail of the scorpion is up. The characters Cloud and Barret are fighting the scorpion.

First picture has the text:
Cloud ”Barret, be careful”

Second picture has the text:
”Attack when its tail is up”

Same scene, but a bit later, after you have already had enough time to follow the instructions in the previous picture:

”It’s gonna counterattack with its laser.”

This mistranslation has claimed countless victims of players getting counterattacked due to the misleading instructions

The concept of ”skämskudde” meaning ”a pillow you hide your face behind out of second hand embarrassment from something you see” is great btw!

Screenshot from the wiktionary entry for ”skämskudde”:

Etymology

From skämmas (“to be embarrassed”) +‎ kudde (“pillow; (couch) cushion”), referring to the idea of seeing something so embarrassing that one gets the urge to hide one's face in a pillow or couch cushion, for example when watching a television program from a couch. The word has been attested in writing from at least 2002 and was possibly used as early as the 1980s.[1]

Pronunciation

IPA: /²ɧɛmsˌkɵdɛ/

Noun
skämskudde c

• (humorous) a real or imagined pillow used to cope with the awkward feeling caused by witnessing something embarrassing; literally "embarrassment pillow".

let’s not forget about the humble Pentagonator

A pentagonal commuting diagram with different associations of w*x*y*z on the corners, where the multiplication is the monoidal product in a monoidal category. The edges are labeled with variations on the associator natural transformation.

for the intersection of computer science and abstract mathematics, there’s also the lambda cube en.wikipedia.org/wiki/Lambda_... serokell.io/blog/look-at...

A cube with arrows on the edges. Each corner is labeled with a lambda followed by some symbols, signifying which of the Pure Type Systems they represent.

The different directions are labeled by what of types and terms can depend on what in the type system, giving rise to polymorphism, custom type constructors and dependent types.

it’s because danish is the french of the nordic languages. they also share having a strange base-20 number system

A map over europe, showing how different languages say the number 92. every country except france and denmark write it as either 90+2 or 2+90, france writes it as 4x20+12, while denmark writes it as 2+(5-0.5)x20

screenshot of documentation:

Section: Deprecated and unmentionable

function:
accursedUnutterablePerformIO :: IO a -> a

This "function" has a superficial similarity to unsafePerformIO but it is in fact a malevolent agent of chaos. It unpicks the seams of reality (and the IO monad) so that the normal rules no longer apply. It lulls you into thinking it is reasonable, but when you are not looking it stabs you in the back and aliases all of your mutable buffers. The carcass of many a seasoned Haskell programmer lie strewn at its feet.
Witness the trail of destruction:

Deprecated: If you think you know what you are doing, use unsafePerformIO. If you are sure you know what you are doing, use unsafeDupablePerformIO. If you enjoy sharing an address space with a malevolent agent of chaos, try accursedUnutterablePerformIO.

the bot didn’t seem to work, so here you go:

Screenshot from the linked news article:

Drug-resistant gonorrhea, a form of the widespread sexually transmitted infection, is considered an urgent health threat worldwide. The United States has just lost its ability to detect it.

Among the Centers for Disease Control and Prevention employees fired on Tuesday were 77 scientists who, among other work, gathered samples of gonorrhea and other S.T.I.s from labs nationwide, analyzed the genetic information for signs of drug resistance, and readied the samples for storage at a secure facility.

No other researchers at the agency have the expertise, or the software, to continue this work. The abrupt halt has stranded about 1,000 samples of gonorrhea and other sexually transmitted pathogens that had not yet been processed, and perhaps dozens more headed to the agency.
There are as many as 30 freezers full of samples that now have no custodians, said one senior C.D.C. official who spoke on condition of anonymity for fear of retaliation.

"We were just really shut down midair, like there was no warning," the official said. "It was just completely unplanned and chaotic."

If we would try to make a naive version of the blog alg without laziness, we could try running it twice, the first time with a dummy value. however, this version has exponential complexity with respect to depth, since each recursive call will also call it's children twice

lamBad : (Expr -> Expr) -> Expr
lamBad f =
dummy = f (Var 999)
a = maxBV dummy + 1
Lam a (f (Var a))

something like this: this is somewhat similar to the rejected option in section 2.1 of the paper: emilaxelsson.github.io/documents/ax...

Code implementing an ability and handler for providing unique names:

type Expr
= Var Nat
| App Expr Expr
| Lam Nat Expr

structural ability Unique where
newUnique : {Unique}Nat

withUniques : Nat -> '{g, Unique} a -> {g} a
withUniques n0 x =
impl : Nat -> Request {Unique} a -> a
impl n = cases
{ pure } -> pure
{ Unique.newUnique -> resume } ->
handle resume n with impl (n+1)
handle x() with impl n0

lam : (Expr -> {Unique}Expr) ->{Unique} Expr
lam f =
a = newUnique
Lam a (f (Var a))

app = App

> withUniques 0 '(lam (x -> x))
> withUniques 0 '(lam (x -> app (app (lam (y -> y)) (lam (z -> z))) x))

yes, indeed! it traverses your structure in a depth-first left-to-right order, by order of your definition. the same holds true for derived Traversible instances. Here's the generated code, dumped using -ddump-deriv and slightly cleaned up:

$A screenshot of the code generated by deriving Functor, Foldable and Traversible on the binary tree "data Tree a = Tree (Tree a) a (Tree a)". I have modified the code slightly to make it more readable, by applying hlint hints and replacing prefix functions with their corresponding inline operations. The full code follows below: {-# OPTIONS_GHC -ddump-deriv -dsuppress-uniques -dsuppress-module-prefixes #-} import qualified GHC.Base import qualified Data.Foldable import qualified Data.Traversable data Tree a = Tree (Tree a) a (Tree a) -- deriving (Functor, Foldable, Traversable) -- Generated code: instance Functor Tree where fmap f (Tree a1 a2 a3) = Tree (fmap f a1) (f a2) (fmap f a3) (<$) z (Tree a1 a2 a3) = Tree ((<$) z a1) z ((<$) z a3) instance Foldable Tree where foldr f z (Tree a1 a2 a3) = foldr f (f a2 (foldr f z a3)) a1 foldMap f (Tree a1 a2 a3) = foldMap f a1 <> (f a2 <> foldMap f a3) null (Tree {}) = False instance Traversable Tree where traverse f (Tree a1 a2 a3) = liftA2 Tree (traverse f a1) (f a2) <*> traverse f a3$
