@UnrelatedString I was thinking about the broadcasting from 1d to 2d or 2d to 3d. My reasoning for the current behavior is that by repeating at the highest rank it reduces the chance of needing to use two chars R,. Although I think repeating at the lowest rank might be more intuitive/useful.

@UnrelatedString For your case: "asdf","123";Rl}k gets what you want, and would be the default case if I did it the other way. But if you wanted it the way the it is now and I changed it, then you would need to do ;R, any thoughts?

Unrelated String

@DarrenSmith Repeating at the lowest rank definitely does feel more intuitive to me

Darren Smith

@UnrelatedString I've flip flopped on this so many times... I think I agree, but I'll change it and test it out on a bunch of examples and see how often that made things worse

Unrelated String

Makes sense!

Definitely the best way to make design decisions :P

Dannyu NDos

@noodleperson This is why I commited apostasy.

Unrelated String

Does remind me, it wouldn't save anything here, but if double commas end up being necessary somewhere else often enough it might be worth thinking about reworking the caps/commas system somewhat so that, say, caps means unvectorize once and comma means unvectorize twice--so R, becomes r,, R,, becomes R,, etc. and there's no redundancy

but that also feels like a bit of excessive/overly-golfy complexity

Darren Smith

00:57

Yeah I think it would theoretically be better, but so far hasn't come up. It isn't really more complicated but I do like people not having to use the capitalization system at all if they don't want to. I'll make a note though could be worth changing

Unrelated String

Could also keep the current behavior for verbose tokens but change it for single chars, but that probably would be confusing

I got a solution to the last APL Challenge which works fine in the playground but the site fails it :(

emanresu A

Might be invisible chars?

or trailing spaces ?

mousetail 'he-him'

emanresu A

Huh

mousetail 'he-him'

emanresu A

You need a capital X

mousetail 'he-him'

07:01

Ah

The x in the monospace font used really does not look like a capital

Q: Number of complete binary unordered tree-factorizations of n

For prime p, the factorization tree is a single vertex in just one way so that a(p) = 1. For composite n, the two subtrees at n are a split of n into two factors n = d * (n/d), without order, so that a(n) = Sum_{d|n, 2 <= d <= n/d} a(d)*a(n/d). a(1) = 1 is by convention, reckoning 1 as having a ...

I'm scared for Tuesday

I'm predicting like 60/40 on Trump winning

I've got friends who are trans, I've got friends who are undocumented immigrants, I've got friends whose parents re undocumented immigrants. Like I also have this definite fear over things like democracy, but it's suddenly very real

@emanresuA We can do separate posts I guess

but yeah like...I think the harris campaign has been doing a pretty shit job

They're letting the other side define the conversation on basically every issue

On immigration they're straight up just like "yeah we hate immigrants too, and we're almost as good at it!"

and despite the economy being the issue more people care about than anyone else, including like all of the swing voters, they've just let the republicans do their normal bullshit on that and barely challenged it

Unrelated String

Oh

Wow yeah yikes

rydwolf

I mean, they rightfully criticized trump's tariff thing, but that's like one offhand comment

Unrelated String

You'd think that would be like the ONE thing they'd double down on

rydwolf

right??

Unrelated String

considering basically every other issue is like

already polarized just by Trump existing

rydwolf

15:11

Like for once culture war shit isn't what everyone's talking about and they've just thrown away the opportunity

Unrelated String

Like they could just ignore everything else because anyone who cares more about most other things is going to see their vote as for Trump or for Not-Trump

rydwolf

I'm honestly not too worried on the election-denial front, since it seems like a lot of their strategies are just 2020-on-steroids, and people are getting ready to fight back. But a straight up trump victory is decently likely IMO

Unrelated String

yeahhh

I feel like the election-denial fears might even be somewhat fabricated just to suppress voter turnout 💀

rydwolf

Oh interesting, that's not a take I've heard yet

Unrelated String

Just something I thought of right now

Ginger

15:19

@rydwolf maybe it'll be fine...?

all we can do is hope

a trump victory sure wouldn't be good for me!

Unrelated String

🤝

My egg may have genuinely picked the worst possible time to crack

But at least there's some safety net in state governments. maybe

Ginger

funny how that happens

Maybe It'll Be Fine

Unrelated String

yepppppppp

rydwolf

took me a sec to parse that as a metaphor lol

Ginger

insert terminology familiarity xkcd

rydwolf

15:21

@Ginger Maybe, and I really really really hope so

Ginger

"queer terminology is so second nature to us transfems that it's easy to forget the average person only knows the names of one or two sexualities"

@rydwolf yeah :/

genuinely idk what I'll do in the event of a Trump victory

Unrelated String

😭

Ginger

probably just carry on with life and hope in vain nothing terrible happens

rydwolf

I sure love hanging in the balance between slow, agonizing progress and a quick and sudden descent into horror

Ginger

so true

Unrelated String

15:23

I guess the silver lining to not having started HRT yet is not having to be afraid of suddenly stopping it :P

rydwolf

What are y'all's reads on what JD Vance would do if trump died and he took office?

Ginger

ahaha

Unrelated String

ahahahaah

Ginger

@rydwolf this is a terrifying prospect

trump is incompetent and malicious, vance is competent and malicious

and like even if Harris wins there's still gonna be unrest

rydwolf

Really? The read I've gotten on vance is that he's just power-hungry. Like, I think he's only doing the maga stuff to use trump as a way to get to power, I feel like he'd be more of a traditional social conservative if left to his own devices

Unrelated String

15:25

@rydwolf I honestly don't have a very strong impression of him overall, but I feel optimistically like at least some of the crazy shit he'd try to do would not actually succeed

Without Trump's charisma or cult of personality he definitely wouldn't be as much of a "strong leader" in general

Ginger

@rydwolf I think he would be far more effective at actually doing the various things Trump promises than Trump himself

Unrelated String

but also yeah that

rydwolf

though there's always the possibility that enough trump-centric superstructure has been built up that it could carry on without trump himself

@Ginger I feel like he wouldn't want to though

Ginger

hopefully we won't have to find out!

Unrelated String

He'd at least be willing to to secure continued support from the MAGA platform

Ginger

15:27

@Ginger the upside is that we're at least a bit more prepared this year

Unrelated String

No real reason not to

Ginger

I doubt we'll get a repeat of jan 6, at least

Unrelated String

yeah

rydwolf

Mostly off topic but I've been thinking about a backup career plan

If I do biochem, what if I went to med school and became a doctor

I feel like there's lots of opportunity for a large impact if I went into things like gender/trans stuff

There are also combined MD+JD programs if I really wanted to pursue the president thing in parallel lol

Unrelated String

ahaha

Ginger

15:29

@rydwolf if you did this there would be a nonzero possibility that you could handle my HRT, which would be extremely funny

rydwolf

and in worst case scenarios, if HRT was illegal or something, being both a doctor and a lawyer, and someone very willing to do illegal things, would be a valuable set of traits

Unrelated String

real

Ginger

real

rydwolf

My only worry with pursuing the doctor thing is that I can't really change my mind. It would require enough time commitment that I'd hit a point where it's that or the old dream, no real way to pursue both

Like, I'd have to drop ROTC, for one

And I'd have to do clinical experience stuff in college

Ginger

in your position? I would do it

Unrelated String

15:34

That could be a positive development :P

rydwolf

...I think I'm going to email my advisor

Ginger

I would take a large chance at improving the world a little bit over a small chance of improving the world a lot

6

Unrelated String

And also yeah don't you kinda resent how much the military trajectory constrains your self-expression

...yeah good idea

Ginger

^

rydwolf

@Ginger this is something I needed to hear

I am going to give myself 48 hours to think this over

Ginger

15:35

~~I tend to behave in a utilitarian fashion, to be fair~~

Unrelated String

@rydwolf ~~implying your advisor isn't going to take a week to respond~~

Ginger

lol

rydwolf

I did not realize how much weight this path has put on my shoulders

i almost just started crying lmao

Ginger

I had a joke about free will but maybe this is not the time

🫂

Unrelated String

🫂

rydwolf

15:37

maybe deciding at 16 years old I must be the most powerful person in the world was not healthy

Unrelated String

Eh, I feel like that's a fairly natural thing to grow in and out of

And conversely it doesn't mean there's anything immature about you for having actually followed through on keeping the option open

You're just cool like that

Ginger

true!

rydwolf

it feels very silly emailing my advisor to let her know that I "no longer plan on being president of the united states" and we must "plan accordingly"

Unrelated String

😭

You could just say your political ambitions have waned

rydwolf

I do still think I might pursue that, but definitely not from the ROTC angle

Unrelated String

15:40

Yeah there's all kinds of ways you can flex into a smaller scale political career

rydwolf

I've been trying to be someone I'm really not to get there but I think just doing what strikes a genuine balance between enjoyable and impactful and going from there is a much better strategy

Unrelated String

You can even have a large scale impact through advocacy without holding any office at all

rydwolf

this is true

Unrelated String

@rydwolf 🫂🫂🫂

rydwolf

"TNB changes the entire course of my life" was not on my to-do list today but I'll take it

Unrelated String

15:41

:3

Seggan

@rydwolf honestly Vance would be a lot better than trump imo

@rydwolf this

Ginger

~~it would be funny if we don't have free will and this is the universe where you would've become president had I not said anything~~

rydwolf

LMAO

Unrelated String

LMAO

Ginger

casually changing the course of history

rydwolf

15:50

okay so I have 48 hours to come up with the funniest possible fake reason for leaving ROTC

Ginger

unspecified incident involving a cat and Donald Trump

which is technically true

Unrelated String

SE chat would have been discontinued 5 years ago if a rogue time traveler hadn't determined that anonymous bribes to keep it online weren't the simplest and most effective way to erase the Tosh presidency from history

7

@Ginger YES

rydwolf

Actually that's pretty good..."I'm quitting" sounds WEAK and PATHETIC while "unspecified incident" sounds MYSTERIOUS and SUBVERSIVE

Unrelated String

ahahahahaha

rydwolf

actually I guess this means I can do something I've wanted to do for a long time

Ginger

15:52

"more pressing matters require my attention. farewell"

Unrelated String

pffffffffff

rydwolf

We have to report interactions with the police (tickets, arrests, etc.), which they call "civil involvements"

Unrelated String

OHHHHH

rydwolf

And I've been wanting to ask "is it still a civil involvement if I run from the cops but they don't catch me?"

which ofc I'd never do if I actually planned on continuing with the program lmao

Unrelated String

lmao

rydwolf

15:56

okay so now the real question: do I still go for a russian degree if I'm not doing rotc?

I really like my planned schedule for next semester, but it's more than half russian classes

Unrelated String

It'll be fun

You can also decide to drop it later if it ends up not working for you

rydwolf

yeah, it's more just, if I take a bunch of those classes now, then drop it, I wasted an opportunity to take a bunch of chem and other assorted classes

Unrelated String

mmmm

You could try to put together an alternate schedule that mixes more chem in and weigh the specifics

Seggan

@rydwolf knowing a second language is good

Unrelated String

A lot of the classes for the Russian major would be more than just language

Seggan

15:59

and IMO russian is an interesting language (yes im biased but still)

Unrelated String

and also if you can find the motivation then learning outside a classroom setting can be comparable if not better

But classrooms also give you unique opportunities that pure self-study has nothing like

Seggan

and for some reason theres like 3 russian speakers here and in the discord

rydwolf

@UnrelatedString yeah, I'll probably still take the language ones

ykw yeah I think I'll stick with russian, or at least some sort of language/writing/humanities major

okay so I think I'll act like everything is normal with ROTC, ask the question about running from the cops on thursday, then let everyone know on Friday that I'm leaving due to the unspecified cat+trump incident

that also gives me time to change my mind lol

Unrelated String

Sounds good!

user

@rydwolf Pick some war movie where one of the soldiers gets into trouble with their drill sergeant at boot camp or something. Pretend that's your story. If anyone challenges you, dig in and deny every having seen that movie, insist that you truly did, say, steal your ROTC instructor's motorbike and crashed it into his house or something

rydwolf

16:07

"I fell asleep on night watch duty"

user

@rydwolf Oh I like this

rydwolf

ooh if I can make the implication that the running from cops was also part of the cat+trump incident, even better

Unrelated String

ahaha

rydwolf

alternatively, they've seen my AFOQT scores now, so what if I make them try to beg for me to stay

Adám

18:11

@mousetail'he-him' Ah, I can make the checker ignore case. Thanks!

Adám

19:12

@mousetail'he-him' ↑ is now live.

CMQ I have a full rank binary matrix. I have one sort of operation which is to add one row to another. I want to transform the matrix so that there is one 1 per row . How can I find the minimum number of operations needed to do that? All addition is mod 2

Simd

19:51

Is there a polynomial time algorithm for this?

rydwolf

20:36

I just spent half an hour doing the math to determine if a 1:1 mix of pepsi and milk would hydrate you or not, based on its osmolarity and that of urine

Unrelated String

I see.

rydwolf

(The answer is it would, just not very well)

Unrelated String

...Wait, is normal Pepsi actually net dehydrating

rydwolf

This is what I get for questioning the correctness of an article titled "pilk in the anthropocene"

Unrelated String

Or is it just really really close

because I feel like I've

@rydwolf PFFFFFFFFFFFFFFFFFFFF

rydwolf

20:38

It's net hydrating

emanresu A

I regret learning about the existence of pilk

Unrelated String

I feel like I've heard of people who refuse to drink water and subsist entirely on soda

rydwolf

But it's like half the osmolarity of urine/seawater (which are strangely close)

Unrelated String

and they probably die at like 40 from other problems with that

rydwolf

so you're getting way less water than if you just drank the water component of it

Unrelated String

20:38

but I assumed they still did get more or less hydrated

Seggan

@rydwolf makes sense, the ocean is made of fish pee

Unrelated String

@rydwolf lmao

rydwolf

@rydwolf oh and it's subtitled "A modern dialectic of oppression"

Unrelated String

LMAOOOOOOOOO

Ginger

if I had a nickel for every conversation I am observing from a safe distance with PPE on where urine has been brought up, I would have two nickels

Unrelated String

Seggan

~~but ure not actively participating~~

rydwolf

> Whenever I pull up to a function, and I see that there is Pepsi present, many may recall me boldly inquiring, “where the milk at?”.

> I have concluded that there is no such thing as a radical negation of this dialectic specifically, but there are two possible proceedings. We as a society can alter our interpretation of the world and the diversity of human culture in a more post-structuralist manner: viewing the act of drinking pilk through a more quasi-anthropological lens, such that we embrace cultural relativity as a maxim to live by, and entirely reject any notion of objectivity.

emanresu A

incredible

Simd

@rydwolf tuff

@rydwolf this is god's work

att

21:41

@Simd this should be closely related to finding its inverse

Simd

21:59

@att I did wonder about that.I could compute the inverse but then what?

att

one way to compute an inverse is to perform row operations on an augmented matrix

Simd

@att yes. That's the way I know to compute the inverse

But is that going to be the smallest number of row operations possible?

lyxal

22:16

@emanresuA this is why they gave us r/a flags in chat

I did not need to know pilk existed

It's an abuse of my sanity and confidence in society to not do silly food things

att

@Simd that is why i say related

Simd

22:40

@att I think it's a good idea
