Just cloudy at the moment

Same as HN's description actually

hyper-neutrino

it's supposed to rain tonight, tomorrow, the day after, and friday

Redwolf Programs

@Wezl Isn't that just TNB but with less people?

Wezl

@RedwolfPrograms maybe

except discussion about CGCC is off-topic

(general discussion is fine)

caird coinheringaahing

So the direct opposite of TNB :P

hyper-neutrino

granted, TNB is hardly a discussion about CGCC itself either.....

caird coinheringaahing

20:03

Case in point :P

hyper-neutrino

but it is on-topic, if it ever comes up

caird coinheringaahing

CMC: Given x and y, calculate gcd(gcd(x, y), lcm(x, y))

Wezl

right but still there are a few annoying messages daily, reminding me of the existence of main

Redwolf Programs

Isn't that just gcd(x, y)?

caird coinheringaahing

@RedwolfPrograms shhh :P

Wezl

20:04

gcd -- three bytes, probably mathematica or some other language if it's greatestCommonDivisor

hyper-neutrino

:P

if you really want the exact calculation ignoring the fact that it's gcd(x,y), it's ggæl in jelly i think

since it's a 2,2,2-start in a dyadic chain, it starts with value equal to GCD

Redwolf Programs

Aww, I just drafted a challenge then realized it was basically just simplifying fractions :/

hyper-neutrino

then matches the 2,2-rule and GCDs the value with LCM(left, right)

caird coinheringaahing

CMC (a better one): Given a list positive integers, return the maximum gcd of all pairs (no replacement). e.g. [9,2,3,4,5] -> 3 (gcd(9,3))

hyper-neutrino

Œcg/€Ṁ

unfortunately cannot use gþµFṀ because then it will GCD each number with itself, which would just be the same as Ṁ

XβĠC₀2

caird coinheringaahing

@hyper-neutrino Jelly really needs a single byte version of /€

Redwolf Programs

I should really switch the argument order for combinations of n items

CMC: Randomly shuffle an array

hyper-neutrino

Ẋ

caird coinheringaahing

How did you have enough time to copy-paste that?

hyper-neutrino

from random import *;shuffle

Redwolf Programs

20:12

ṁO in Ash

caird coinheringaahing

I had just opened the atoms page by the time you posted that

hyper-neutrino

@cairdcoinheringaahing ctrl-N + type "atoms" -> open the bookmark + search "shuffle" + copy + paste

Redwolf Programs

Why not just AltGr + ., X

hyper-neutrino

because my keyboard layout isn't right for that and also i don't memorize jelly atoms

Redwolf Programs

US EXTD layout FTW

caird coinheringaahing

20:13

@RedwolfPrograms Because if I could type Jelly atoms, none of y'all could step to my FGITW game :P

hyper-neutrino

i just have en us and jp mozc, maybe i should get extd US so i can be super speed

i don't remember which atoms are which symbols though

Redwolf Programs

i mean the whole point of the Jelly code page is that it's all typable with US INTL/EXTD :p

hyper-neutrino

i just remember which functionalities exist and what to search for to get them

caird coinheringaahing

I can remember most of the atoms, but I'm awful at finding them

I always go "I can just scroll, it's slower to Ctrl-F", then spend a minute scrolling :/

hyper-neutrino

nice

Redwolf Programs

20:16

I accidentally rediscovered how to simplify a fraction

hyper-neutrino

ayy nice

Redwolf Programs

I was thinking about how you can divide x / y by finding all of the factors in x but not y

caird coinheringaahing

Reminds me of when I first started JHT and came up with a 20 byte program to simplify [a,b] (representing a/b) :P

Redwolf Programs

Then I realized that'd be the numerator and what's left is the denominator

hyper-neutrino

i remember the good old days of having way too much time so i was able to learn jelly and spend a good amount of time practicing in JHT and having leaky and eric help me

caird coinheringaahing

20:19

:P

No offense to Leaky or Eric, but I keep discovering their old Jelly posts and, at least for a while, they really weren't good :/

Redwolf Programs

I need to write a program for the final exam for my computer science class, but the only requirements are that it has to use at least one function (?) and I somehow can't think of anything

hyper-neutrino

i mean, jelly is a rather hard language to learn IMO :P

@RedwolfPrograms write a function to randomly generate a valid function

caird coinheringaahing

The number of superscripts, ©® and ¤ were crazy :P

@hyper-neutrino Yeah, and their more recent ones are much better, but it was just crazy to see "jelly, 25 bytes" by Erik and "Jelly, 12 bytes" by Dennis that was just the same but tacit

hyper-neutrino

i think i tended to use a lot of superscripts and totallyhuman tended to use a lot of $. or the other way around

until we got better at the whole tacit thing. and also the 3- and 4-link combinators were added :P

caird coinheringaahing

Ɗ and Ʋ are life-savers :P

@RedwolfPrograms What do you mean by "use at least one function"?

Like, the program has to have at least one function f(x, y) { } in it?

Redwolf Programs

20:23

You have to have at least one (in their words) "subroutine" that is used in the program

As long as it does something it's valid

caird coinheringaahing

Ackermann function maybe?

Wezl

wow, CGCC chat: the one place on the network where people will do your schoolwork :P

hyper-neutrino

For anyone who's interested, Peilonrayz and Sᴀᴍ Onᴇᴌᴀ have been elected over on CR (I recall some of y'all voted)

caird coinheringaahing

Oh, I didn't even notice that Vogel stepped down so it was 2 seats

@hyper-neutrino Take a look at how it played out

Peilonrayz was initially 3rd, but managed to beat both Mast and pacmaninbw on the secondary votes

hyper-neutrino

Ah, that's interesting to see

caird coinheringaahing

20:29

Peilonrayz beat Mast by a margin of .27 of a vote :O

hyper-neutrino

oh wow...

user

@RedwolfPrograms We've got climate change

@Wezl Wait really? Could y'all find a power series for $\ln(x+1)$ please? :P

Wezl

make that a CMC and people will solve it

hyper-neutrino

that's the harmonic series

caird coinheringaahing

I understand the mathematic :P

user

20:40

CMC: Power series for not $\ln(x+1)$ centered at $c=0$. Please also provide the interval of convergence. :P

@hyper-neutrino Lol wasn't expecting someone to actually answer that

hyper-neutrino

i mean idk what your school policy is, if you're allowed assistance i would be willing to help as in offer advice rather than just give the answer :P

user

Thank you for helping me participate in academic dishonesty /s

caird coinheringaahing

@user Try calculating the continued derivatives

user

Oh that's a good idea

caird coinheringaahing

@user I'm surprised that's homework for you. When we started doing Taylor series, they just gave us a list of commonly used series, and that was one of them

user

20:44

They haven't started calling them Taylor series yet (although Maclaurin series were foreshadowed)

I might have missed this one in the video explaining it, though, I'll have to check again

How much rep can I get from you for that? I'd like at least +100 :P

caird coinheringaahing

I'll happily award a +250 bounty :P

user

20:46

Throw in some imaginary brownie points and you've got a deal

caird coinheringaahing

Done :P

user

Done

Where are my bounty and imaginary brownies?

hyper-neutrino

they'll arrive in 4-6 business days

caird coinheringaahing

I'm not sat on a beach in the Caribbean yet :P

user

It's too late now

Redwolf Programs

20:49

I sat on a beach in the caribbean once but they got all mad at me for bringing my nukes

A bunch of scary submarines showed up

user

You should have disappeared to the Caribbean right after we made the deal - that's when I temporarily stole your identity and took on your legal obligations. Unfortunately, you chose not to go there, so now your identity and legal obligations are back, along with a bill from an Indonesian casino :P

Also the pacific missile testing resort in Hawaii isn't as good as the reviews said, the service was awful

They were really rude

hyper-neutrino

would like to bring some attention to this again: codegolf.meta.stackexchange.com/questions/22177/…

this should be a pretty quick change so i can probably do this soon and unfeature it

?????

caird coinheringaahing

@hyper-neutrino Pretty sure I pinned that :P

hyper-neutrino

well, the transcript still says I pinned it, but chat says it is not pinned

user

20:57

@hyper-neutrino You can do both?

hyper-neutrino

also am i not supposed to be able to cancel stars

user

You're a mod

hyper-neutrino

oh wait, i must do it from the starboard

cringe

caird coinheringaahing

Yep :P

hyper-neutrino

can't do it in chat or via the transcript :/

caird coinheringaahing

20:58

For some reason, you can't cancel from the message itself :/

hyper-neutrino

i wish you could do stuff like this from the transcript. otherwise you have to join the room which announces your presence (it's also why when linking problematic things in TL i have been instructed to link the transcript rather than the room, which i forgot about once)

caird coinheringaahing

I just don't mind "announcing " my presence. It's not like anyone's going to make any judgement on me entering a room, and if they do, so what?

TL is different tho

hyper-neutrino

i mean, canceling stars isn't really something for which you need to really worry about people knowing that it's you who did it

i wonder what the (public) room with the highest ratio of mod activity (as in messages) is :P

A username

Hyperneutrino's domain?

caird coinheringaahing

Probably the Math.SE Mod Office

Q: Is anyone else familiar with the game 21 ? Everyone playing stands in a circle. The aim is to count to 21. The first person says "1" and people continue from there. If anyone says the same number at the same time, the number resets to 0. The person who says 21 is "out". Last person out loses

user

22:31

I vaguely remember playing a game like that sometime

Sounds like the opposite of blackjack

(btw it's also a basketball game, but I think that one's different)

Redwolf Programs

Sounds like it could be a KotH

caird coinheringaahing

Guess what I'm writing up rn :P

user

Someone: Says literally anything
Redwolf: Sounds like it could be a KotH

Redwolf Programs

That reminds me, I haven't worked on Hunter-Gatherer in a while :(

I am way too busy

user

There's an optimal strategy to that game, though

(unless you're shaking things up, of course)

caird coinheringaahing

22:36

@user "I just golfed a byte off this answer!" "Sounds like it could be a KotH"

@user What's the optimal strategy?

Redwolf Programs

Ash (haven't seriously worked on it in nearly a month), Hunter-Gatherer, my game, school, various programming projects, the blog, the chat bot for the Guild, etc.

Too much stuff to do :/

user

I think whoever goes first can make it so they always win

caird coinheringaahing

How? The entire game works on people not speaking at the same time as you

user

Oh wait, wrong game

caird coinheringaahing

Yeah, it's not the "count up to 3 more numbers" 21

user

22:38

Strategy just in case anyone makes a KotH about that (apparently whoever goes second wins)

This one should be more interesting

Redwolf Programs

Maybe I should just make a userscript that blocks me from CGCC for a certain amount of time each day :p

I already made one that makes me wait 40 seconds first, but that just made me more inefficient because I suddenly would get patient

user

Just use Lyxal's userscript but with a higher probability of getting rickrolled

Eventually, you'll associate CGCC with humiliation and stop coming here :P

Redwolf Programs

Maybe I'll just add a really scary looking timer at the bottom of the page whenever it's focused, and once that timer reaches zero for the day I'm blocked until UTC midnight

user

How do you make a userscript block you from a site?

Redwolf Programs

Just document.write("no")

user

22:41

lol

Redwolf Programs

Actually I'm going to go make that

It could actually work

user

Is there any way to find your first message(s) in chat?

I don't get SE chat. Searching for b yielded messages that didn't contain a single b, while searching for a yielded 0 messages.

Redwolf Programs

I've been trying that too

I think they filter a and the

user

So that's why I only have 7 messages containing the most common letter in the alphabet

Redwolf Programs

e?

user

22:48

Yeah

Redwolf Programs

(or, since I pretend e doesn't exist, t?)

user

t works out great - I get 13 pages of results

Redwolf Programs

Same here

34 pages for me

24 for TNB only

I don't know what's up with e

user

Too yellow to show itself! :P

Oh I just realized all my bolded messages were showing up for b because HTML (ノ°Д°）ノ︵ ┻━┻

Redwolf Programs

Wow, I had no idea chat search was that bad

This might be my earliest in TNB

Ugh, I want to write up my koth idea, but koths are so much effort :(

Redwolf Programs

Not if you automate it with the API

caird coinheringaahing

No, writing the koth is effort

Redwolf Programs

This one seems fairly simple, though

Just link to this conversation and add no additional explanation :p

caird coinheringaahing

I'm struggling to decide between the input being just n (the highest count), the list of the last round's counts, or the entire history

user

The entire history would be good

Redwolf Programs

Reduced knowledge is also interesting sometimes

user

Lets you analyze other bots' strategies

Btw any feedback? Is there any way I can make it more interesting?

@AaronMiller I just wanted to say thank you for all the issues you've been raising in Vyxal lately: where others may dread bug fixing, I appreciate that someone is actively looking to help improve my language. Keep the issues coming I say!

@RedwolfPrograms decaying averages have their uses too you know

Aaron Miller

@Lyxal No problem! Also, I just spent about 30 minutes trying to figure out what was going wrong with the Ė command before I realized that it returns 0 after executing the passed string. Is that intentional?

Lyxal

Yes, it is supposed to return 0

Because the string executed impacts the stack anyway

Count up to 21 21 is a game my teachers had my classmates and I play in order to kill some time. The game works as follows: All contestants stand in a circle. The aim is to count to 21, one by one.

CMC: Given an integer \$n \in (1,2,3)\$ and a list L, calculate the decaying mean of L. The different values of \$n\$ should correspond to different Pythagorean means (arithmetic, geometric, harmonic), you may decide which n is which

Aaron Miller

23:49

What does CMC stand for?

Bubbler

VTC as unclear: define "decaying mean"

@AaronMiller CMC = Chat Mini Challenge

caird coinheringaahing

n = arithmetic, L = [1,2,3,4,5] -> 4.0625, n = geometric, L = [1,2,3,4,5] -> 3.7884, n = harmonic, L = [1,2,3,4,5] -> 3.35664

@Bubbler "decaying mean" means that you calculate the mean of the first two elements, then the mean of that and the third element, then that mean and the fourth etc.

Wezl

Why n in 1,2,3 instead of just 3 distinct values?

caird coinheringaahing

¯\_(ツ)_/¯

It's a CMC, plus that could lead to people saying "takes the code for arithmetic as input for that etc."

Bubbler

Otherwise I can take three values as lambda x,y:(x+y)/2, lambda x,y:(x*y)**.5, lambda x,y:2*x*y/(x+y)
