I recently moved to America to avoid being drafted into the war on emus

@Wasif How are you measuring chat activity?

@cairdcoinheringaahing weekly stats

@Wasif This week Redwolf's posted 1.3k messages, I've posted 1.1k and Lyxal's posted 1k

Hmm... Currently Lyxal dropped from 1.2k to 1k msg per week???

An hour ago Lyxal was 1.2k

THAT IS INSANE

@Wasif Stop digging, or else...

@Lyxal what no

i'm in australia

Australia can hold more than two people at once

@cairdcoinheringaahing My mistake, user (currently Lyxal) has posted 1k, Lyxal (currently user) has posted 779

I need to shut up

I am waiting when user will come back from Australia

okay this is causing too much clutter in chat and too much confusion; i'm going to revert everyone back to who they actually are

:(

I kind of agree, the pfps were funny but this is just confusing

@Lyxal Since I can't upload pictures when editing your profile, I've reverted you to your own identicon; in case you need it, I have a link to your old PFP here.

@hyper-neutrino mod abuse!! eleven!! :P

brb changing pfp to an 11

(Seriously tho, thanks, it was getting a bit out of hand)

Okay from now on we pretend this whole thing never happened got it :P

what whole thing?

Yeah

Not sure, I have this faint recollection we were talking about something

Yes, the brain tends to block out painful memories

So, the system doesn't remove synonym tags, even if they're on 0 questions

That's half the point of synonyms right?

Instead, it allows them to clog up the last page of tags when sorting by popular

How do you delete them, then?

You can delete them by getting a mod to merge them

you merge them without synonym and wait until 3AM UTC

i don't know if i can unsynonymize tags

@RedwolfPrograms For commonly used ones, yeah, but how often do you think someone's going to tag a king-of-the-hill with koth

True

I might write up a merge request at some point with some of the tags that there's no point keeping as synonyms

Anyone know how to decompress a sparse matrix?

@user wouldn't the compressed form be [[5, 8, 3, 6], [1, 1, 2, 3], [0, 1, 2, 1]]?

idk

IA starts with a 0 I think

Ugh I do not feel like working on Ash right now

But I've barely written anything in the last three weeks

This is me doing homework

i have demonstrated stupidity

i cannot read

HN's editing my messages stop the mod abse!111!

status-norepro

:P

it's impossible to decompress the compressed form you gave into the matrix in your example without having the intended size of the end result as input

at least, you need the number of columns

Oh right

Anyone got a link to the Code of Conduct? I can't find any links in the site footer

codegolf.stackexchange.com/help/conduct

@Wasif Thanks!

welcome

any suggestions for a name for a tree-based esolang? (not a golfing lang, but not as tarpit-y as BF or flak)

Branch?

easy treesy

Monkey business

TREE (Tree related easy esolang)

treesolang

Epiphyte

treesolang is taken

What else is unique about it?

i like the recursive acronym :P

the data manipulation is inspired by AVL trees' self-balancing mechanism so you can rotate the data around nodes

it's not recursive because 'tree' in the name isn't TREE

oh true

Yeah, I wasn't thinking about a recursive acronym, but you can make it one

Upside-down trees?

Please give a name suggestion for a stack based esolang

i think i'll go with branch. thanks everyone :D

Stack

I cannot think any good name

@hyper-neutrino \o/

@Wasif Stacks

@Wasif Stack Exchange, but it's already taken

@Wezl :)

@cairdcoinheringaahing What? There is no language named Stack lol

@user Stax would be cooler, but it is taken

Stackdogs

I do quite like why Stack Cats is called that :P

stackcats is a really cool idea lol, i have no idea how to do anything in it though

It doesn't even have to do with cats

But it;s palindromic

Yeah

stackcats

Then why it is related with cats

stackrelateddetalerkcats

The language is based around programs being palindromic, and stack based, so stackcats. Add in a space and some capitalisation to give it a better name

How about Stack [fill_name_of_animal_here]

Stack humans, because humans are my favorite animal (also my least favorite)

Stack Homo sapiens

@Wasif because cats reversed is stac

Didn't knew it.....

Then the name should be "stac cats" instead

But it has to include "stack", so it's stackcats

stack kcats

.-.

.- -.

Here's my personal name generator in python: print(list(map(lambda x:''.join(x)[:-1]+'x',list(permutations('stack')))))

Say which is the coolest

@Wasif I am removing this answer as per our policy for handling invalid submissions, since permutations is not defined in standard Python and you must include the bytes for importing that function from the itertools module. Feel free to edit to a valid solution and flag for undeletion.

(/s)

also BTW you don't need to list() the permutations result because map accepts any iterable

@hyper-neutrino which answer

@Wasif your code (in your chat message) (it was just a joke since you didn't have import itertools/permutations in your message)

I can no longer edit the message

don't worry about it i simply made a joke, you didn't do anything wrong

@Wasif The "/s" indicates HN was joking

@Wasif Stack Cats is actually a really interesting language, and the language name works of the central premise. Essentially every program is an odd number of characters, where the second half is a visual reflection of the first half (e.g Wv\<*>/vW). The commands in the second half deliberately undo what was done in the first half, so the program boils down to finding a central character which changes the behaviour of the program

Essentially all the commands that are visually palindromic (e.g. *, ^, +) are self-inverse, and all "reflected" characters ([], \/ etc.) are inverses of each other

Programming in it is highly non-trivial, and most submissions in it use brute-force, or the (...)*(...) construct which only executes the contents of the second bracket. There's a +1100 deadlinesless bounty for figuring out how to code non-trivial programs in it, that don't use the above construct

this strongly reminds me of matrix conjugates in linalg

anyone wanna make a high-performance fungeoid?

I've probably spent half an hour on google streetview following a power line in rural colorado and I still haven't managed to find a substation

...why?

fishing for chat stars, probably

@Wezl Sure

I've always wanted to find a power station by following a normal low voltage one power line and following it all the way to the source

not exactly sure how to start, though

Learn C, maybe

i'm implementing rotations (the same ones AVL trees use for rebalancing) in my esolang; what should a left rotation do if the node is its parent's left child or right rotation as a right child?

well I guess designing it

@RedwolfPrograms bit of a weird thing to have always wanted to do, but you do you

@user that was the first language I learned. Unfortunately, I don't have that much experience though.

Oh cool

i know a bit of C (using it for an esolang right now, and wrote some things for CS146 in it) so i might be able to help but idk if i know more than you lol

I sometimes wish I'd learned a language like C++ first to get a knowledge of low-level stuff

If anyone's interested in collaboration, I can make a chat room

I know a little bit of C

@RedwolfPrograms should I take that as a "yes, I wanna learn too"?

No, just a "I also know a little bit of C but I forgot the context for somebody saying they knew it"

i feel like c is way better to start with than c++ even if c++ is more generally useful because c++ is also c++

Fair enough

C is a lot "simpler"

I think C++ is better to learn because, if you restrict yourself to only the modern good parts, then it's modern and good

Whereas literally none of C is modern or good

@pxeger what modern and good parts

hey, can I get some feedback on this challenge codegolf.meta.stackexchange.com/a/22110/77516 ; i literally cant tell if the challenge is even interesting :<

seems decent

Is it possible to change a room name later after creation?

do bounties count against the rep cap?

Yeah

Yes

@pxeger No

@pxeger No

you should probably clarify if you can replace the leftmost digit with a 0 @ManishKundu

so can 123 become 23

might want to clarify whether or not you can replace a leading digit with 0

...yeah

@pxeger If they did, 500 rep bounties would be useless

Full of ninja's :P

full of extra apostrophe's too :P

@cairdcoinheringaahing then why do they count towards the Mortarboard, Epic, and Legendary badges?

oh right i'll mention that then, I just kept a case like that in the examples before

@pxeger The max rep you can get in a day (not counting repeated events cause then it's infinite) is +717

@user please note that message was ninja'd by user

> Earn 200 daily reputation 50 times

@Wezl :)

It doesn't say "Hit the reputation cap 50 times"

@cairdcoinheringaahing it says "Earn at least 200 reputation (the daily maximum) in a single day"

I also ninja'd a couple other people

@cairdcoinheringaahing Wait I got over 1200 once

From Bubbler's bounties

@pxeger Even more interestingly: I awarded a +500 bounty (so a gross loss of 500), then got +200 from upvotes (net loss of -300) and it counted towards Epic

@user "not counting repeated events cause then it's infinite"

@Wezl created, even though the dialog said it might be a duplicate of ash :)

@cairdcoinheringaahing where's the 17 come from?

Assuming you hit +200 repcap (say 20 upvotes on different posts), +500 bounty awarded, accept an answer and get an answer accepted

@cairdcoinheringaahing Oh

@pxeger Yeah, Mortarboard's a weird one in phrasing

@pxeger +15 from having an accepted answer, +2 from accepting an answer

Although, if you also count edits, then you can get 719

so they don't count towards the rep cap either?

@pxeger Nope

Rep earned from upvotes and edits only is subject to the cap

So the rep cap should just be called the upvote cap

@pxeger But that could get confused with the 30/40 votes per day cap

oh ok fair enough

@user IIRC Jon Skeet once hit +5000 in a day or something crazy

lol

Then, again it's Jon Skeet

The most rep Jon Skeet has ever earnt in a day is the last 4 digits of pi

Jon Skeet could probably reverse the digits of pi using a GOL program

I stand corrected. The most Jon Skeet's ever gotten in a day is +871 on Mar 9 2012

Ha, I beat Jon Skeet at something :P

@cairdcoinheringaahing wow, and he didn't even get a +500 bounty o.O

This dude made +1230 in a day once

Didn't even repcap

wow

That user had a huge spike in 3 months

The last time Jon Skeet didn't hit the repcap was Feb 14th (only got +160)

meanwhile me who never even hit the daily cap ;-;

O.o On his first day on SO, all the way back on Sep 26th 2008, Jon Skeet repcapped

guy is a legend

In fact, as far as I can tell, he went a solid 5 years hitting the repcap every single day from 2011 to 2016

o.O

wow

If Legendary was changed to "repcap 150 days in a row", he'd have it at least 12 times before 2017

@user ∘.○

@rak1507 ⍤

Jon Skeet has more Great Answer badges than you have badges

Jon Skeet has more Nice Answer badges than a lot of you have reputation (anyone with <8.2k)

Jon Skeet has more badges than you have reputation (anyone with <18.4k)

don't you hate when your cgcc account just doesn't exist

@cairdcoinheringaahing 2 +500 bounties (and one +50) in one day...

@somebody ?

reparenting to cgcc user just

doesn't work properly

wack

either that or my cache is broken

i've refreshed your profile again, it now looks right on my end lol

You know how exactly 3 users have gotten the Steward badge here (complete 1000 reviews in a single queue)? How in the hell did this dude hit 100k?

The author of that is the legendary voter gnat

@cairdcoinheringaahing idk if my answer is valid please can you do jelly magic to check all the inputs

I have no idea how to do that I just threw together things until it worked

Yeah, looks valid to me

yay

Can't believe I forgot about division :/

lmfao

there's probably a shorter solution

I just don't know how jelly worked and wanted to FGITW :P

I so hope someone makes brownie points redeemable for brownies

it should be something like Æṣ÷⍥’ where ⍥ is over in APL

or not quite

@rak1507 Test suite for all test cases

I'm sure there's a 5

:Æṣ’$ seems to give the right results for the test cases but not sure if it's provably correct

It is!

So long as n doesn't equal 1, floor(x / n) = (x - 1) / n (if x-1 is divisible by n), and n = Æṣ’ equals 1 if Æṣ equals 2, which it can never do as it's always 1 + something where something != 1

So yes, it's valid

Fun fact, Æṣ has only been used in 10 answers (no counting any posted after the 11th)

can :Æṣ’$ be done without the $ somehow?

I don't really understand jelly

@rak1507 Æṣ’:@ works, but it still 5 bytes

yeah, I had that one

oh well

feels like :@ and ÷@ would be good one byters

Between them, they're only used 22 times in Jelly answers

that can't measure how many times they could save a byte though

No, but it gives a good indicator

fair enough

I thought I was near the end of a homework assignment and I'm still less than halfway finished :/

oof

@hyper-neutrino [Bernie sanders standing on the street during the fund-raising period] I am once again asking for a profile refresh

Hi real lyxal

> I am once again asking for your moderation support

@Wezl yes.

I actually kind of like your identicon

are you interested in the future of funges?

It's too spiky though, which is a pretty consistent issue with the SE ones

Is there a way to simplify ln(x / 2)?

I honestly can't remember

It'd be ln(x) - 2, right?

No wait

@RedwolfPrograms ln(x) - ln(2) iirc

Oh turns out the issue was I didn't put parentheses after ln :|

Aww se chat bio isn't long enough to fit the entirety of this week's meme

So I'll finish it here

call up Sean Hannity, it's a bold strategy, inside our galaxy. We're snapping back to reality, oh there goes gravity, mom's spaghetti

@hyper-neutrino but seriously tho may I have a pfp hard refresh?

I don't know why SE identicons are spiky (other than extra entropy)

They also tend to be ugly colors

Yes

I would much prefer the funny word than the identicon I used back when I had little rep

no idea why a horizontally symmetrical 7×7 or 9×9 grid with a preselected saturation and lightness and a random hue wouldn't work, and those look good

@Lyxal here use mine :)

There's no use if the chat doesn't actually update the pictures

Finally finished my math homework. Time to learn me a haskell (for great good).

:O nice

I have once again hard refreshed a user profile.

enjoy your funny words, magic man

Heck yeah

"heck"? who are you and what did you do with lyxal

Wait hang on

Frick yeah

@hyper-neutrino that's when I have to follow scratch tos

ah

I don't like bountying challenges like hello world because I get notified of new answers, and for a brief second I'm unsure if I'm still redwolf or if I'm actually an experiment by a super high rep long time user and the entire life I thought I knew was simulated in GoL for fun

You're not any of those things

You're redwolf

Get it right or don't bother asserting identities

@RedwolfPrograms it's time to update your chat bio

But I like my compressed rickroll :p

@RedwolfPrograms hmm

sad

Hi, Lyxal and Redwolf Programs!

@ASCII-only That's my favorite XKCD :p

@user <insert witty way of greeting here>

@Lyxal damn you!!

<insert reply that lacks creativity>

ḭ is a builtin for flipped division?

@rak1507 Whoa there

<insert greeting that's not only boring but way too late>

i am now living in constant fear that user, lyxal and redwolf have merged into a single entity
