The author is still listed as "You" :p

You can also use a mutation observer instead of a setInterval

That'll make it faster and a tiny bit less resource intensive

@hyper-neutrino

hyper-neutrino

yep, makyen mentioned that in TL too :P

especially for people who have many chat tabs open

Redwolf Programs

Want me to write that part? Mutation observers are annoying :p

I can just steal it from one of my other scripts

pxeger

Website designers that have abnormal scrolling (stepped or non-linear) can go absolutely fuck themselves (I'm looking at you, Apple and IBM)

hyper-neutrino

oh sure thanks :P i'll take a look at this tho, it has more than i need and i have some ideas i might be able to implement with this

Redwolf Programs

^^

caird coinheringaahing

7:03 PM

@pxeger Imagine not using Fibonacci scrolling :P

Redwolf Programs

var observer = new MutationObserver(() => {
    // Your code
});

observer.observe(document.getElementById("chat"), {
    attributes: false,
    childList: true,
    subtree: true
});

That's my code

hyper-neutrino

@RedwolfPrograms stackapps.com/a/8269/51037 is probably better than mutation observers

Redwolf Programs

Looks like that's called prior though

caird coinheringaahing

@hyper-neutrino That's the only goddamn post on the network I've seen that actually has a list of events

hyper-neutrino

@RedwolfPrograms oh :c

setTimeout time then lol

Redwolf Programs

7:05 PM

Unreliable and slower :p

hyper-neutrino

wait that's actually what the post recommends lol

Redwolf Programs

Just repcapped on Stack Apps lol

hyper-neutrino

@cairdcoinheringaahing ikr, i've been trying to find a full proper list for a while

lmao

maybe i can set up a chatbot to help me stalk flags :P

caird coinheringaahing

I've figured out most of them :P

EVENTS = {

        1: 'Message posted',
        2: 'Message edited',
        3: 'User joined',
        4: 'User left',
        5: 'Room topic/name changed',
        6: 'Message starred/unstarred',
        #7: 'Unknown',
        8: 'Bot was pinged',
        9: 'Unknown',
        10: 'Message deleted',
        #11: 'Unknown',
        #12: 'Unknown',
        #13: 'Unknown',
        14: 'Event beginning in a few minutes',
        15: 'User changed access status or changed RO status',
        #16: 'Unknown',

That's in OSP's chatbot.py :P

hyper-neutrino

oh nice

what if i just entirely replace SE's chat client

just hook into its events and display my own site in its place

Redwolf Programs

7:06 PM

I was working on something like that

hyper-neutrino

oh lol

Redwolf Programs

Got distracted and forgot about it though lol

hyper-neutrino

lol

make a command line chat interface using a chatbot :P

caird coinheringaahing

> 11: 'FileAdded',

Why is that even a chat event?

Redwolf Programs

Image maybe?

hyper-neutrino

7:08 PM

is that for if you upload as a chat message, to distinguish it from a normal message

caird coinheringaahing

lemme just experiment

Nope, uploading an image doesn't send an event object (aside from the message event)

hyper-neutrino

strange

caird coinheringaahing

> 2021-05-10 20:12:28 Got activity {'t': 124248482, 'd': 1}

That's not how activity logs are supposed to look:

2021-05-10 20:11:26 Got activity {'e': [{'event_type': 1, 'time_stamp': 1620673885, 'content': 'Testing', 'id': 124248433, 'user_id': 274572, 'user_name': 'caird coinheringaahing', 'room_id': 120733, 'room_name': 'OSP testing', 'message_id': 57943258}], 't': 124248433, 'd': 1}

Very weird O.o

hyper-neutrino

se chat go brrr ¯\_(ツ)_/¯

user

Am I the only one here who likes the font change?

caird coinheringaahing

7:16 PM

Pretty much

pxeger

I like it being Noto Sans

Wezl

I like it

pxeger

I definitely don't like Cantarell

hyper-neutrino

i found them okay but roboto >

user

I like Segoe UI or whatever this is

pxeger

7:16 PM

It would be Segoe UI on Windows

user

@hyper-neutrino That's odd, a robot doesn't like Roboto? :P

hyper-neutrino

(?)

user

I can't find it now, but I definitively proved somewhere that you are a robot

hyper-neutrino

when did i say i don't like roboto tho :P i said i found the change to ubuntu alright but i preferred roboto

Redwolf Programs

I'd interpret that comment as hyper liking Roboto

ninja'd

user

7:19 PM

Oh well, of course a robot would like Roboto

hyper-neutrino

also i deny all allegations of being a robot

user

(I interpreted it as "other fonts are okay, but roboto makes me angry (>)")

@hyper-neutrino And of course a robot would say that :P

hyper-neutrino

on the contrary,

2 days ago, by user

@hyper-neutrino For a second there I was afraid you'd caught on to me. Phew!

pxeger

"but roboto >" looks like hyper failed to write a proper emoticon and just left it as >

hyper-neutrino

i think i have evidence that you're a robot

user

7:20 PM

@pxeger Yeah, I thought it was >(

@hyper-neutrino Oh yeah? Then prove it, robot

hyper-neutrino

"roboto >" was intended to mean "roboto > (whatever else)" in this case being ubuntu. lol

Redwolf Programs

Maybe you're all robots and I forgot I'm a turing test examiner

user

@RedwolfPrograms Or maybe you're a robot and we're examining you

Redwolf Programs

Of course not...

looks around

user

Or maybe we're all robots and cyborgs are examinining this

caird coinheringaahing

7:21 PM

Clearly we're all bots coded by Dennis in Jelly to create "competition" on the site

user

Arnauld was one of his better creations

hyper-neutrino

i am an early prototype with too many glitches only kept around for backwards compatibility

user

Now I know how CGCC managed to graduate - Dennis just created a ring of bots :P

@hyper-neutrino Be thankful you're not me. I was written in Java

caird coinheringaahing

Luckily, we all sanitise our data inputs :P

hyper-neutrino

@pxeger that message can't stop me, because I can't read!

Redwolf Programs

Security tip: Name all of your tables "waffles" to make it harder to find them

user

@cairdcoinheringaahing Speak for yourself, my data inputs, like my macros, aren't very hygienic

Redwolf Programs

7:24 PM

Repcapped on meta :p

user

@hyper-neutrino What exactly does this help with?

Redwolf Programs

Not showing up in a room when you're just reading a message

Good for moderation stuff

user

Oh, nice

hyper-neutrino

it's useful for the TL if someone accidentally posts a room link, instead of a transcript link like you're supposed to

definitely made that mistake before; it's a pretty common mistake :P

but it's not great if a heated discussion is going on to have like 5 moderators suddenly enter the room at once

nicknamed the "blue storm" :P

caird coinheringaahing

boss music begins playing

Redwolf Programs

7:29 PM

It's much better to track them to their home address and send a team of highly trained, armed community managers to kick their door down and stop the argument at the source

caird coinheringaahing

If the CM team had the resources to do that, SE would be a much better place :P

user

Mar 1 at 21:21, by Redwolf Programs

We could fly to SE's headquarters, then in the dead of night we break in. We pick the lock on the server room and inject a custom payload. The site goes down for a little while. Then, we sneak out through the air ducts. We fly back to our homes, and the next morning the site's magically updated. A few people wonder how, but the meta posts magically vanish. Nobody will ever know.

Redwolf seems to have a history of ~~extreme~~ completely rational approaches to problems

:P

John Dvorak

outcome: people complain, their posts vanish, people complain about shadowbanning, big flamewar breaks out

user

s/their posts/they

Redwolf Programs

That's what the armed CM team is for

user

7:33 PM

@user ^ That way, no one continues complaining

@RedwolfPrograms Wars or ~~terminating~~ ~~kidnapping~~ ~~imprisoning~~ ⎕⎕⎕⎕⎕⎕⎕⎕ people?

Redwolf Programs

They're for...uhh...negotiations

user

"" Here, I think you dropped a pair of double quotes

7:49 PM

lmao

bye. :)

Redwolf Programs

Getting that question migrated was OP

I got to keep the rep on mother meta :p

The cowsay question hit HNQs. Should we keep it there, or remove it?

Wezl

they're encouraging you to post on MM first :P

Redwolf Programs

Doesn't seem like a good example of a quality question for the site

Given that it's more than 40% downvoted

hyper-neutrino

i agree with removing it

idk why something with such a bad score even got put up there

Redwolf Programs

The answers are the main thing the formula cares about

hyper-neutrino

7:59 PM

anyone against removing it?

alright i've kicked it off of hnq

Redwolf Programs

Oops I left a console.log in the source code of Custom Fonts

I'll delete it, then re-add it next update I guess

hyper-neutrino

lol

Matthew Daniels

hi. :D

Redwolf Programs

Hi!

Matthew Daniels

event starting in a few hours, right?

Redwolf Programs

8:09 PM

Oh no I'm not ready lol

We need some CMCs

Wezl

4 hours I think

ngn

@RedwolfPrograms now that many people are willingly running your code in their browsers, you could try something more naughty :)

Matthew Daniels

what is that?

@Wezl yes, it is 4 hours.

Wezl

@ngn github.com/RedwolfPrograms/userscripts/pull/…

Matthew Daniels

what is CMC?

Wezl

8:10 PM

chat mini challenge, where we do code golf (usually) but with less restrictions or formality

Redwolf Programs

Chat Mini Challenge

Matthew Daniels

also in 4 hours, I'm posting another question.

what challenge can I think of?

well, I don't know because you guys are going golfing.

Redwolf Programs

Note: We need some CMCs for the Mini Golf. Feel free to post any drafts here for feedback.

Matthew Daniels

maybe I thought of one.

arithmetic functions.

Redwolf Programs

Draft: Take an array of numbers. Take the sum, but where every second item is negated.

Matthew Daniels

8:14 PM

write a function that operates the 4 arithmetic operations.

Redwolf Programs

Can you clarify that?

Matthew Daniels

or program.

Wezl

Draft: Append two matrices [[0,1],[4,5]], [[2,3],[6,7]] => [[0,1,2,3],[4,5,6,7]]

hyper-neutrino

Draft: Given a matrix of numbers, return the sums of each row and the products of each column (as two lists or something like that)

Matthew Daniels

I'll write it in how I would write SE questions.

Redwolf Programs

8:15 PM

@Wezl Will the two matrices have the same dimensions?

Wezl

@RedwolfPrograms sure

Redwolf Programs

Draft: Take an arithmetic operator in the form of a function (one of addition, subtraction, multiplication, or division), and return one of +, -, *, or / depending on what it is

Wezl

time to do some CMC sniping :P

Redwolf Programs

For example, f((x, y) => x + y) would be +, and f((x, y) => (2 * x - 2 * y) / 2) would be - (as it behaves identically)

caird coinheringaahing

@RedwolfPrograms That makes it so much harder

Wezl

8:17 PM

no .toString().find(...)?

hyper-neutrino

how is 2*x-2*y equivalent to x-y or am i reading into this wrong

caird coinheringaahing

Are the inputs guaranteed to always behave identically to one of the four operators?

Redwolf Programs

I'll revise the wording to a blockbox function

@hyper-neutrino No I'm just stupid

hyper-neutrino

lol

Redwolf Programs

@cairdcoinheringaahing Yes

caird coinheringaahing

8:19 PM

Draft: Given an integer n, output an integer x such that [n+x, n-x, n×x, n÷x, n*x] are all unique integers (* is power)

Wezl

clarification: takes only numbers (because language may have overloaded operators where (2 * x - 2 * y) / 2 is not strictly the same) (?)

Redwolf Programs

Let's get some string manipulation drafts

Matthew Daniels

lmao

whoops, not done.

Redwolf Programs

@MatthewDaniels You can't use markdown in multiline messages

Also, you might want to use the sandbox instead of asking for feedback here

caird coinheringaahing

@RedwolfPrograms I think this is intended to be a CMC draft :P

Matthew Daniels

8:22 PM

alright, thanks.

Redwolf Programs

Oh :p

Matthew Daniels

it was supposed to be.

lmao

Redwolf Programs

There won't be any formatting for the CMCs, they're just chat messages :p

You don't have to worry about being super specific or adding a backstory, they're kind of informal

caird coinheringaahing

@MatthewDaniels "Given n, x and a symbol from +,*,-,/, output the result of applying that operation to n and x" Is that right?

Matthew Daniels

okay, I'll post it in the Sandbox then send it here if your bot won't get to send it.

Redwolf Programs

8:23 PM

If it's a CMC no need to sandbox

I misunderstood :p

caird coinheringaahing

Only post challenge drafts to the sandbox, not CMCs

Matthew Daniels

lmao

@caird I didn't think of using the operators as char inputs, but that can be a thing too.

Redwolf Programs

JS, 0 bytes. Takes input by appending n then the operator then x to the program ;p

Matthew Daniels

in my original post. the needed input for the arithmetic operator should be a char and should use either a, s, m or d.

Redwolf Programs

Usually the input and output aren't very strict for CMCs

caird coinheringaahing

8:26 PM

Interesting that I can't modify the event information, even as an RO

Not that I'm going to, but I'd expect to be able to

Redwolf Programs

Same

Matthew Daniels

@Redwolf what about challenges posted in the main site?

Redwolf Programs

what about them?

Matthew Daniels

input and output.

Redwolf Programs

You have to be a bit more specific there, but usually the I/O restrictions are fairly loose

caird coinheringaahing

8:27 PM

Those should be well specified. That can be strict, but doesn't always have to be

hyper-neutrino

Interesting that I can't change the event info, even as a mod

Matthew Daniels

ah, ok.

@hyper lmao

Redwolf Programs

I have an amogus computer charger

Matthew Daniels

wait, that seems like a funny name I shouldn't use.

caird coinheringaahing

I believe I can just cancel the event and reschedule it, but that'd require all registered users to reregister

Redwolf Programs

8:28 PM

There's a little thing on it to let you clip the wires together, and it's shaped like a crewmate

Wezl

@MatthewDaniels you might specify "either a, s, m or d" (on main) but it doesn't make sense to specify that the input would be a char because many languages don't have a char type

Redwolf Programs

You could also just say they can choose any four unique characters

Matthew Daniels

@Wezl ok. :D

caird coinheringaahing

If you're looking at posting that as your challenge here, don't. It's a duplicate of about 15 existing challenges

Matthew Daniels

more lmao

I'm waiting for 8:00 am in my place so I can post my physics question. and even(t) for the event.

user

8:31 PM

CMC draft: Join a list of strings using another string

@MatthewDaniels Have you sandboxed it?

Matthew Daniels

the?

Redwolf Programs

@user Seems a bit too easy

hyper-neutrino

sandboxed what? i don't think physics has a sandbox and event stuff is just drafting

also that cmc seems way too trivial lol (just imo). pretty much everyone is just gonna submit like "Jelly: j" or something

Redwolf Programs

Draft: Collapse all identical characters

caird coinheringaahing

Isn't that just unique(x)?

Do you mean identical adjacent characters?

Redwolf Programs

8:33 PM

hiii I''m wriiiting this would become hi I'm writing this

Matthew Daniels

the physics question? I made a draft on it in the Ask A Question page, and it should be at Physics SE in 12:00 am utc.

hyper-neutrino

Draft: given a string, find the longest continuous substring such that all characters it contains show up an equal amount of times within it (for example abbccddef would be bbccdd), return any subset of valid answers if there are multiple

Redwolf Programs

Oh, that's a good one

hyper-neutrino

@RedwolfPrograms where is the comma coming from

Redwolf Programs

My (not really) fat fingers

More like my inaccurate fingers

Delfad0r

8:34 PM

@cairdcoinheringaahing Is n positive? Also, is it guaranteed that there is at least such an x (for instance I believe the problem is unsolvable for n=1)?

Matthew Daniels

Draft: draw a certain shape that is 8x8. the code should also look like the same shape. 8 lines should be used in the program then.

Redwolf Programs

@Delfad0r Why not 2?

caird coinheringaahing

@Delfad0r Yes and yes (i.e. you may assume so/the input will always have an output)

Anush

@hyper-neutrino nice question

Redwolf Programs

3, -1, 2, 1 / 2 (or 0), 1

caird coinheringaahing

8:35 PM

@RedwolfPrograms 1÷2 isn't an integer

hyper-neutrino

it is if you're brave enough

Matthew Daniels

@caird lmao

hyper-neutrino

@hyper-neutrino should i post this to main actually?

Redwolf Programs

After the Mini Golf :p

hyper-neutrino

that took me like 1 second to realize who pinged me. brain smol moment ಠ_ಠ

Redwolf Programs

8:36 PM

@cairdcoinheringaahing Why not just unique numbers?

Matthew Daniels

man, I enjoy being here at this chat room while I can't make my room yet.

Anush

@hyper-neutrino yes

caird coinheringaahing

@RedwolfPrograms ¯\_(ツ)_/¯

Redwolf Programs

Makes a lot more sense IMO

hyper-neutrino

but if i put this challenge into the mini golf then too many people would've solved it and it just becomes a fgitw contest when i post to main

Redwolf Programs

8:37 PM

Hmm, true. Save it for main :p

It's a good challenge

Draft: Given a multidimensional array, return how many dimensions it has

user

@hyper-neutrino I thought it was a code golf challenge involving physics

Redwolf Programs

For example, [] is 0, [1, 2, 3] is 1, [[1, 2], [4, 8]] is 2

user

The shape of a multidimensional array may also be interesting

Matthew Daniels

@Redwolf simple, but nice. fits well to be a CMC.

user

@user (assuming the input isn't jagged)

Redwolf Programs

8:38 PM

Draft: Determine if a multidimensional array is jagged

Stolen :p

Matthew Daniels

let me grab my early morning snack first.

Redwolf Programs

Halfway, I did think of it as user was saying that

user

@RedwolfPrograms :(

@RedwolfPrograms ?

Redwolf Programs

But I took some of your wording

I thought of it on my own beforehand though

caird coinheringaahing

@hyper-neutrino 8 bytes in Jelly, so it's not trivial

user

8:40 PM

@RedwolfPrograms Are you talking about this? I'm confused now

hyper-neutrino

ah. cool. might post to main then; 8b is a healthy target for jelly imo

Redwolf Programs

@user Oh I didn't know that existed already

lol

user

Wait if you didn't see that, why'd you think you "stole" it?

caird coinheringaahing

2 mins ago, by user

@user (assuming the input isn't jagged)

Redwolf Programs

^

user

8:41 PM

Right, but Redwolf's checks if the input isn't jagged, mine assumes it isn't already

Redwolf Programs

Close enough :p

user

Although if you copyright your question or something, I'd be happy to sue you :P

Redwolf Programs

Draft: Take two (cartesian) coordinate points. Rotate the first around the origin in 90° increments, and return the one closest to the second point

caird coinheringaahing

Draft: Given a Cartesian coordinate point, output its polar form

Suggestion: Just before the event, we move all these drafts into a gallery room so that people can find them easily, and pin a link to the room

Redwolf Programs

Good idea

user

8:43 PM

Draft: Given a complex number, represent it in polar form :P

Redwolf Programs

We'll start to sort through them maybe a half hour before, and get a list made

Draft: Calculate compound interest

user

Draft: Interleave n lists (too dupe-y?)

Redwolf Programs

@Redwolf Might be boring due to closed form though

caird coinheringaahing

@hyper-neutrino What should the outputs be for: "abbccddef", "abbbbccddef", "aaaaaaaa", "abcdef", "abbccbbe"? (include in the challenge body as some test cases, if you don't want to answer here :P)

hyper-neutrino

bbccdd, bbccdd, aaaaaaaa, abcdef, and any of bbcc, bccb, or ccbb

caird coinheringaahing

8:47 PM

Why isn't the last one bbccbb?

It is the number of times each character appears, or appears together?

Matthew Daniels

hi. :D

I'm back.

had to eat.

Redwolf Programs

Draft: Take a string of test cases, separated by newlines, with the input and output separated with a ->. Return a multidimensional array (with each test case represented as [input, output]) or dictionary of them.

hyper-neutrino

oh. appears total, not together. sorry, should be clarified

Redwolf Programs

Or should I require dictionary?

user

Ooh, this one has practical applications too!

caird coinheringaahing

8:48 PM

@RedwolfPrograms Languages don't always have dictionaries

user

@RedwolfPrograms No, it's just a CMC

Redwolf Programs

Sounds good

Wezl

Idea: delete CGCC, make it an SO question where all challenges are answers, and answers are comments

user

@RedwolfPrograms I'd say tuples and other data structures should be allowed too

caird coinheringaahing

@hyper-neutrino Shame, ruins a 7 byte Jelly answer :(

Redwolf Programs

8:49 PM

@user Sure, it's a CMC

Wezl

Idea: delete CGCC, and remake it but challenges are answers and responses are questions

caird coinheringaahing

@Wezl Cursed CGCC :P

Matthew Daniels

@Wezl that went too far. everything is now a duplicate.

Redwolf Programs

So you respond to answers (questions) with questions (answers)?

user

Code Golf and Coding ~~Challenges~~ Answers

Wezl

8:50 PM

jeopardy Code Golf

Matthew Daniels

and since that is so, I'm sure Area 51 won't get the site launched.

user

@MatthewDaniels I know you're joking, but so many answers are just ports of a better answer

Wezl

makes that an actual challenge format

Matthew Daniels

Draft: take an input, then for each word, set their letters in alphabetical order keeping their repetitive ones, then output the whole thing.

Wezl

sort each word?

Matthew Daniels

8:52 PM

yes.

the way to separate them is from hyphens, symbols and spaces.

underscores count as well.

user

Draft: Subsequences, going out from the center ('ABCD' -> ['BC', 'ABCD'], 'ABCDE' -> ['C', 'BCD', 'ABCDE'])
