take a moment to perform a beautiful long division:

9 divides into 531441 how many times?

thank you for celebrating my special day.

please like this post if you did the math <3

michaelrotonal

as many times as you want. no matter what, 531441 / 9 = 59049.

however, fun fact about 531441: it equals 3¹², and its closeness to 2¹⁹ = 524288 explains why 12EDO is the currently used tuning system

The second Tuesday in June is re-bracketing day! Celebrate by taking a nedible and sending in a napplication :D

my friend wrote a terrible docstring and now i'm going to publicly shame him for it

what the fuck is this??

what he's trying to say is: """ main menu drawing function:

inputs:

- isPlayer0Active (Bool): True when player 1 has joined

- isPlayer1Active (Bool): True when player 1 has joined

returns:

- hasGameStarted (Bool): True when both players have joined (game has started)

"""

but nooooo he had to go and write it as a fucking sentence for some reason

and waste like 5 minutes of my time trying to figure out what the hell this function was actually doing

well your explanation has a bug and his doesn't so

guys did you know the tech in that nefangled machine revolutionized preemie healthcare

yeah the guy who invented them made incredibly precise infusion pumps (as opposed to gravity fed ivs) which not only meant they could give medications to teeny tiny babies safely, it's also used for insulin pumps and portable dialysis machines. the key element is that it's a peristaltic pump so the liquid stays in sterile tubing for safety

(unholy drink cloaca uses it to dispense precise amounts of flavored sugar syrup)

Then how the haters loved him,

As they shouted out with glee,

where's that account that analyzes poems

people hate it when i say "black people getting cancer is racist" but im literally fucking right because systemic racism has led to chemical dumping being acceptable in black/brown neighborhoods and black people have higher rates of cancer as a result

michaelrotonal

"racism causes X" and "X is racist" are not the same statement. i agree with your point though

fun group theory puzzle i had to solve earlier today:

There are 40 elements of S6 that are of the form (ABC)(DEF). They can be placed into 20 equivalence classes by placing inverses in the same equivalence class, and then further into 10 equivalence classes by not caring about the order of elements in a cycle. Choose one element of each equivalence class such that the set of the 20 corresponding elements of S6 is closed under conjugation.

michaelrotonal

My solution is as follows:

Via the Exceptional Outer Automorphism of S6, each element of S6 of the form (ABC)(DEF) is associated with an element of S6 of the form (ABC). The first equivalence class pairs the elements (ABC) and (ACB), and the second equivalence class pairs the equivalence class containing (ABC) and (ACB) with the equivalence class containing (DEF) and (DFE). This makes the problem way easier: Just pick one element of the set permuted by the elements of S6, and take the equivalence classes that keep that element where it is.

#trust me this would not be comprehensible without the color coding

I feel like I need to share this because idk if Europeans are familiar with the presence of Aldi in the US, but at least especially in my area they’ve been growing a lot recently. Like Aldi bought out some local failing grocery chains where I live (Louisiana) and have opened Aldis in all these somewhat rural communities and small towns, which for the record I’m fine with

But as a result of this they are advertising a lot more in my area and also in many cases, the people in these areas have never been confronted with Aldi or any European grocery store. So the ads that Aldi is pushing out to its new US customer base feature a cowboy shopping at Aldi who is explaining to new Aldi customers how Aldi works. Like this cowboy is explaining you gotta put a quarter in the shopping cart and why there are very little name brands. A cowboy is how they want to reach their American customer base. They gave us a cowboy

quirky fourth wall breaking character but theyre just fucking. wrong about the medium theyre in. they keep making references to cinematic techniques and directorial styles and the other fourth wall breaking character is like "dumbass we're in a fucking comic book" and they are in a video game.
