@emanresuA it doesn't work outside of ComputerCraft

@emanresuA TSTL handles that for me :b

@UnrelatedString Indention isn't good in expression. (Picture is size of braces)

Bubbler

I think I saw mixing () and [] in math expressions in an old math textbook (like [(1+2)*3+4]*5)

but it doesn't work well in a programming language

(or was it [{(1+2)*3+4}*5+6]*7?)

Unrelated String

i think mixed brackets for math are usually just ([])

emanresu A

01:23

@Ginger "that" as in ts-to-lua

l4m2

When young I use {[()]}, later just larger () outside

lyxal

writing a report for uni right now, and I'm using SO tag statistics to show community support for different projects, and I so badly want to write [tag:maven] to make it display as maven

but word no do that

because word no se chat

...i'm really starting to see my lack of practical experience with java oop show lmao

falling into so much bizarre overengineering from pretending i have algebraic data types

Bubbler

04:08

Trying to use ADT without language-level support is so much pain

Unrelated String

it feels like i have to go halfway to visitor pattern any time i want to branch on "what something is" without committing the mortal sin of instanceof/downcasting, instead of just pattern matching on constructors and calling it a day

mousetail

05:57

I should really finish Painrose some time

Ginger

11:41

@emanresuA oh yeah it does

I think types for Factorio's API are available as well

Someone

12:10

@Ginger amazing

have you tried the research station from tectech yet? quantum computing be like:

Ginger

12:37

@Someone the what?

mousetail

Is that a factorio mod?

I did not sleep last night

Today's gonna be fun

Unrelated String

hype

lyxal

yeesh

Rydwolf Programs

Yeah I ended up going to bed around 1, laid there 'til 3:30 or so, browsed college-admissions-reddit for an hour and a half 'cause I couldn't sleep, then decided to cut my losses and get ready for the day lol

Ivy day is thursday [fingers crossed]

I've decided on the order I'll open the decisions: Yale, Columbia, Northwestern, Harvard, Duke, Princeton

Plus NYU at some point when I'm around my friend who got into NYU

lyxal

@RydwolfPrograms which one do you want to get into the most?

Rydwolf Programs

It's a stretch but Harvard, followed by Northwestern or Princeton

Unrelated String

13:34

what puts northwestern on the same level as princeton

some faculty you're particularly interested in?

Rydwolf Programs

Nah, the campus looks beautiful from the pictures lol

And I applied for this thing they called like the Integrated Science Program that seemed cool

Unrelated String

ah nice

Rydwolf Programs

The application for it was a google form which was super chill

Unrelated String

huge

Someone

14:05

if the prefix for 60 is hexeconta-, what is the prefix for 64?

isn't it something like hexecontatessera-?

RubenVerg

hexecontatetra?

Someone

no…

I'm specifically thinking about the prefix they used in the NuclearCraft stack-o'-s'more hexeconta(something)

@UnrelatedString in kotlin its not a mortial sin, nor in the modern javas

mousetail

I'd recomend against it in any language

Seggan

@Ginger i should really redo Rol

@mousetail switching against types?

@UnrelatedString have you tried sealed interfaces + records?

mousetail

Yea prefer polymorphism whenever possible

Seggan

in kotlin you can so sealed interfaces + data classes and its very nearly like adts

i do it all the time

Ginger

same

Seggan

15:44

@mousetail yes, of course

but sometimes its unavoidable

esp when working with "adts"

although what i like about "adts" is that polymorphism is possible

Simd

CMQ I have n points with floating point coordinates between 0 and n. Each point has an integer weight. I want to compute for each rectangle with corner at one of the points and at (0, 0) the sum of weights in the rectangle. The output will be n numbers. Is there an implementable way to do this quickly?

hyper-neutrino

as in each point is at some (x, y) with 0 <= x, y <= n?

you can probably toposort this since you have a partial ordering I think

Simd

Yes

@hyper-neutrino that would be cool if possible

I know there is a complicated data structure solution for the dynamic version (points getting inserted and deleted) but I hope mine is much simpler

hyper-neutrino

toposort is apparently linear on DAGs (which this is) and the final summation should be able to be done in linear as well I believe

Simd

What is the graph?

I mean what are the directed edges?

hyper-neutrino

each point has an edge to each point contained in its rectangle i.e. (x, y) has an edge to (p, q) if p <= x and q <= y

though now that I think about this maybe the final sum can't be linear

actually, I feel like if you can efficiently remove all edges between nodes of depth difference greater than 1 (after toposorting) you get at most O(N) additions

Simd

16:16

@hyper-neutrino that's a lot of edges isn't it?

hyper-neutrino

it'd be up to N^2 yeah... but ideally you could get it so that you only have an edge if no point sits between the two

Simd

It seems you are inventing something cool!

Rydwolf Programs

Rate my cartoony calculator UI

Simd

@RydwolfPrograms how did you draw it?

Rydwolf Programs

HTML+CSS

The 7-segment displays use clip-path, and the buttons/calculator body use filter: drop-shadow

Simd

16:26

That's a skill I can't have

You could pose it as a golf challenge :)

It is great

zoomlogo

@RydwolfPrograms i like the "GO"

Rydwolf Programs

It's not a normal calculator...it actually is going to hide a video game :p

zoomlogo

16:43

@RydwolfPrograms ah, makes sense :P

Rydwolf Programs

Is it just me or does this email seem a bit forward to send to someone who hasn't yet been notified of their Harvard or ROTC acceptance status...

> Good afternoon,

The Harvard College Admissions Office would like to match potential class of 2028 cadets with currently enrolled Harvard cadets for Visitas weekend in April. If you plan on attending and would like to be matched with a current cadet please follow these instructions. We strongly encourage you to take advantage of this opportunity. To do so, you'll need to indicate this on your Visitas registration form, which is due by April 4.

Trying not to read too much into it lol

@mousetail Heh, don't look at the Python code for Pip then

@RydwolfPrograms 10/10, looks awesome

Someone

@mousetail no, minecraft

the research station is used to research items for the assembly line

because the assembly line needs access to the data for an item to be able to craft it

Someone

18:05

it's notably used in gtnh

wait, is the research station form tectech, or is it vanilla gt? idk

user

@RydwolfPrograms Ooh what do the buttons look like when you click on them? Is there a depressing sort of animation, like real calculators?

Rydwolf Programs

Right now it just darkens slightly

I could probably make them depressed tho

user

@mousetail It's unavoidable sometimes (e.g. if you're working with types from a library you have no control over)

mousetail

@RydwolfPrograms Rotate them 12 degrees and change the font

Sometimes the possibilities of CSS scare me

user

@mousetail amiller42.github.io/Cursed-Language

mousetail

18:15

Help! Police! Arrest this human!

user

I'm pretty sure the "Welcome to the C u r s ed interpreter" bit used to be a <marquee> but maybe I'm misremembering

mousetail

@user True, there are no hard rules, only recommendations. Sometimes you have no choice, or the other option is even worse

Someone

what is muncee.neocities.org????

Rydwolf Programs

@user It is for me

mousetail

@user Nesting different <marquee> elements with different directions and speeds creates some cool effects

Someone

18:17

bonk

user

@mousetail See, that's what I said to the cop yesterday, but they still gave me a ticket for speeding even though I would've been late to class

@mousetail Ooh, that is deliciously evil

Someone

nyoow

user

@RydwolfPrograms Weird, maybe it's a FF thing, or uBO?

Rydwolf Programs

Maybe

I'm on Chrome with uBO

user

I used to be in charge of the website for this one team I'm on, and I would've experimented with that nested <marquee> thing there, but I recently got pressured into making the website look sane :(

Someone

18:18

@RydwolfPrograms edge with ubo

user

So the page no longer slowly rotates the entire time you're on it

Someone

pressured by who?

the rotation would've been cool

mousetail

@user Actually, I'm sure in sufficiently exceptional circumstances (eg. you where being chased by a dinosaur) the cop would probably forgive you for speeding.

Someone

or fleeing a sideways thwomp

user

If I'm being chased by a dino, I'm probably in a Jurassic Park movie, and if I'm in a Jurassic Park movie, I'm probably the random ugly dude who dies at the beginning of those sorts of movies

Also, the dino would eat the cop

Someone

18:20

dinos probably don't like our flavor tbh

i mean, we're basically popcorn shrimp, and those big bois would need more nutrition

also, all the megafauna is dead, so uhhhh

user

@Someone My teammates. Something about "this is giving me a headache" and "we can't get funding" and "help I'm having a seizure"

So a War of the Worlds kind of scenario

Someone

bruh

the spinny part isn't that bad tho

unless it's flashing like hecc, it shouldn't trigger epilepsy

also, you're getting funding for this joke project?

Rydwolf Programs

@mousetail The courts would, the cops around here would probably still give you the ticket lol

user

I was kidding, I checked guidelines to make sure it wouldn't trigger seizures

@Someone It's not a joke project, it's just the website that I didn't take seriously enough. It's a research project (kind of a useless one but whatever)

mousetail

I think the cops would be pretty busy speeding away themselves

Someone

18:24

@user research project? oooh

user

Nah the dinosaur would 100% eat the cop in a movie

Someone

but then why make it look like a joke site?

user

Unless the cop's one of the good guys

@Someone Because no one cares about our project and I was bored

mousetail

Either they'd fight the dinosaur or run away. Noone is going to just stop to give a ticket.

user

Oh yeah the cop would uselessly fire their gun at the dinosaur until said dinosaur bends down, puts them in their mouth, and chomps them

Rydwolf Programs

18:26

@mousetail Nah you underestimate how misguided a sense of duty our cops are capable of possessing :p

user

Well at least they wouldn't give the dinosaur a ticket

mousetail

I'd be happy to get a ticket if the dinosaur got one too

Rydwolf Programs

If the dinosaur's teeth are long enough would they count as illegally long knives?

user

@user Also if anyone here has money and is willing to donate to a useless computational linguistics research project, let me know and I can send you a link to donate money

mousetail

It's not exactly hard to find laws it's probably breaking, but yes

user

18:29

I'd give it a warning for noise disturbance, as well as jaywalking if it's on the road

Also indecent exposure

Rydwolf Programs

Tresspassing maybe?

Ooh cattle aren't allowed on roads, maybe dinosaurs would fall under that

mousetail

Since horses are allowed on roads I assume it's legal for it to jaywalk?

user

Horses are probably an exception, right? No one rides dinos

Simd

@hyper-neutrino you might be able to do it in O(n^2 log n) by sorting a few times...maybe

Rydwolf Programs

One thing I noticed that's kinda funny is that the local small airport has those goofy ahh grate things that cows can't walk over, to keep loose cattle from getting onto the tarmac

user

18:31

> goofy ahh

Rydwolf Programs

Can you mush sled dogs on a public road, I wonder

mousetail

Fun fact: In the Netherlands, a group of at least 6 people is considered a vehicle for road traffic laws purposes and is allowed on roads provided they follow all other traffic laws

user

Okay lyxal give Rydwolf his account back

Rydwolf Programs

I'm just such a sigma rizzler I fanum taxed Rydwolf's account creds (fr fr no cap)

@mousetail ~~Human centipede time~~

mousetail

18:32

Legally it's caller "procession" but I'll submit a bill to change the name to that

user

@lyxal Okay that's a fairly straightforward policy, thanks

Hourly update: I have thrown eggs at 0 people so far today. I am up 1000% from my yearly average of 0 eggs, but down 45% from my weekly average of 0 eggs

@mousetail wtf how

19:28

@mousetail wait so i can go running on the highway with my 5 friends

"but sir i wasn't speeding!"

19:45

@Simd First, replace the floating point coordinates with consecutive integers by sorting and renumbering. Then, go through the points in order of increasing x, and increasing y for equal x. Maintain a Fenwick tree holding, for each value of y, the total weight of points processed so far with that y value; then each point's answer is obtained with one query to the Fenwick tree. The time complexity is n log(n).

Someone

@RydwolfPrograms wait, what?

Simd

@m90 I like this! It looks like a coding competition type answer. Are you a competitive coder?

m90

@Simd I did some of those back in secondary school, but less often after that (and now even less, now that Google ended theirs).

Simd

20:37

@m90 my guess was really from the use of Fenwick trees

Ginger

21:20

@RydwolfPrograms don't make jokes like that, I don't know what's real anymore :p

Q: Break an integer into even- and odd-indexed bits

Objective Given an integer \$n\$ interpreted as two's complement binary, output two integers, namely the integer consisting of \$n\$'s bits at places of \$2^0, 2^2, 2^4, \cdots\$, and the integer consisting of \$n\$'s bits at places of \$2^1, 2^3, 2^5, \cdots\$. Note that the input may be negativ...

Dannyu NDos

Requiring to deal with a negative input prevents many loopholes, right?

lyxal

no?

it just makes everything harder if anything

Dannyu NDos

I mean, you cannot just input a finite bitstring and break it.

lyxal

...that's why you restrict input to being an integer

Dannyu NDos

Though, negative integers are still integers.

lyxal

23:29

taking a string when a number is expected isn't allowed by default

Dannyu NDos

Oh.

lyxal

you can take "5" if the input is 5, but "101" would be a no no

unless ofc it was the only way to take input. in which case, no amount of banning things will help

also, what representation scheme are you using for negative numbers?

Dannyu NDos

Two's complement binary.

In this way, nonnegative integers start with infinitely many zeros, and negative integers start with infinitely many ones.

lyxal

you should probably mention that in the challenge

Dannyu NDos

Good; edited.

lyxal

23:40

now about those infinite 1s. Wouldn't they impact the result of splitting the bits of a negative number?

also, afaik 2's complement requires a fixed/finite bit-size for integers

I feel like the negative number requirement makes the challenge less about splitting bits and more about figuring out the negative number system

Dannyu NDos

But there's an easy solution for negative inputs: Bit-not the input, split it, bit-not the results, and output them.
