8:14 PM

;-; one downvote and my rep stops being a nice round number

halp how to reset circadian rhythm quickly

I lost 46 rep from a user :_(

Who was Hyper's alt?

@Christopher the two accounts are now merged

@LeakyNun Hyper and what other one?

@Christopher NeutrinoBot or something like that

8:20 PM

@LeakyNun how much rep?

around 500

Oh lol that is not as much as i thought

@HyperNeutrino congrats on the restore! would your votes would be restored along?

@HyperNeutrino When did you get the combine?

@totallyhuman you can DV 3 other people and you should be set ;)

8:34 PM

@Uriel Unfortunately, no :( So pretty much every active user on PPCG has been permanently affected by the SE mistake.

SE/SO

@Christopher like yesterday iirc

@Christopher 46 isn't even bad; Leaky Nun lost like almost 130 rep and Dennis lost almost 150

But I lost my 1k...

oh rip :(

you're only like 2 answer upvotes away, that shouldn't take too long :P

Yeah but it takes me a while

I don't have much time to code during summer

Ah I see.

Well then 4 question upvotes

Ask a good question, no coding required :3

That takes longer

8:38 PM

Depends. If you think of an original and interesting challenge idea you can get upvotes pretty quickly.

No to write challenge

I think the thinking part is the hard part

Depends. I find writing test cases to be the lengthiest :P

^^ applies to most everything

Hey I am at 1k :D:D:D:D:D:D:D

8:39 PM

Yay :D

Congrats :D

Nice

@totallyhuman you passed me in rep so fast

Ouch, you've lost a total of 165 rep to two lost users already :I

I spam questions

I have free time :3

If only I could fetch my old vote stats; then I could go back and redo all of the votes.

@totallyhuman Do you though, or do you just not do homework? :3 :P

8:41 PM

Sometimes :P

@HyperNeutrino Me? One of those was a sock

:P

Oh.

Like your sock or some random person's sock that got destroyed?

Err my sock. I tried to revert it a long time ago and forgot about it. I got a week ban :/

oh rip :/ i was wondering about that. nvm

I told TNB and pinged dennis

But I have lost a lot from removed users over time

K only 70ish

8:45 PM

I count -105 - 50 (not counting the -115)

@HyperNeutrino you can detect all of the edge cases if you try to code a solution in bf

that takes even longer >.<

@HyperNeutrino That 105 was my err other sock testing the bounds of serial votes

>.<

I was doing some tests to check what the limits are

8:48 PM

...

is there any challenge with the goal of simply printing null (0x00)?

I was just wanting to know how sensative the system was and found it to be 100 rep

If you give <100 rep per sock you are gud if you go slow

This is when I would recommend switching to converse about another topic.

@Christopher oh no you're not

@Christopher since most of the site mods are in this room, I have a good reason to believe this will be wrong very soon

8:53 PM

Q: How many cardboard digits do I need?

I need to prepare digits made of cardboard to display some number. I don't know beforehand which number I should display - the only thing I know is that it's not greater than n. How many cardboard digits should I prepare? Example: n = 50 To display any number in the range 0...50, I need the fo...

code-golf number

9:24 PM

@Christopher I think it's also the percentage of votes that go to same IP become I remember one vote set it off :P

there are many many things that feed into it

which I won't list :p

@ArtOfCode list-request

I remember a post specifying what a post has to receive to be considered a 'consensus' but I can't find it, can anyone link me to it?

9:43 PM

Don't think that exists

I think it was the basis for this question:

9

Q: What to do about a fluctuating consensus?

Currently on the defaults for IO this answer is does not have enough positive votes to be instated. At press time it has +11-6 +18-9, defaults are required to have: 5 net votes and at least twice as many upvotes as downvotes. However only a day ago this method was valid (If memory serves i...

> 5 net votes and at least twice as many upvotes as downvotes.

Do we have a challenge for the difference between CE/BCE years?

you mean like 2017CE - 2000BCE = 4017?

Yes except BCE years would just be negatives and there is no year 0. So diff between 5 and 8 is 3 but 1 and -1 is 1.

so (a,b)=>Math.abs(a-b)-1?

in cheddar: (-:1)+(abs)+(-)

9:52 PM

@Downgoat when a and b have opposite signs. Perhaps too trivial even then though

a and b might both be positive or both be negative too

-:1

?

it's a face

@HelkaHomba what might be more interesting would be date subtraction March 17, 2017 - October 23, 1999 = ?

@Downgoat too finicky

9:54 PM

well you don't have to handle weird date changes

hm then there's febuary

ok true

have we had such a challenge?

codegolf.stackexchange.com/q/2910/26997 ?

ah thanks

@LeakyNun I have a question about this answer:

2

A: How many cardboard digits do I need?

Jelly, 9 bytes ‘ḶDœ|/ḟ9L Try it online! How it works ‘ḶDœ|/ḟ9L ‘Ḷ [0,1,...,n] D convert each to list of its digits œ|/ fold by multiset union ḟ9 remove 9 L length

when you say "convert each to list of its digits" do you mean convert each item in the range to a list of its digits?

@Downgoat yes, basically

while you're at that, what does "fold by multiset union" mean?

@totallyhuman fold means reduce

fold [a,b,c,d] by + would be (((a+b)+c)+d)

10:01 PM

ahhh

thanks

halp my circadian rhythm is absolutely broken

@LeakyNun oh, so you basically add all the numbers together, remove 9, and find the length of that number?

@Downgoat instead of "add", I use "multiset union"

and then the rest of your statement would be true

@Downgoat That was just for that specific question, not a general rule.

tries to translate to python

10:02 PM

@LeakyNun so is it like flattening the array?

@Downgoat it is like union, but instead of on sets, it is on arrays

@totallyhuman Its reduce in python

I'll probably write a python solution... now.

Anyone here understand Perl6?

2 mins ago, by Leaky Nun

I'll probably write a python solution... now.

10:07 PM

> Anyone ~~here~~ understand Perl 6 ?

so 2 minutes it is.

@betseg Guessing that's a huge no then?

0

A: How many cardboard digits do I need?

Python 3, 75 bytes lambda n:sum(max(str(j).count(str(i))for j in range(n+1))for i in range(9)) Try it online!

Look, ma, it's shorter than Mathematica

now wait for someone who has more than 100k rep to answer in Mathematica

;-;

10:17 PM

So, no one understands Perl6 here?

Wat

@WheatWizard here

Destructible Lemon

10:34 PM

hi!

hi

;-; either nobody has noticed or nobody knows the answer to my question ;-;

Destructible Lemon

question?

also is anyone here interested in joining my language creation compiler chain thing?

this

Destructible Lemon

@WheatWizard were you the one who made the brainflak quine?

@Uriel ⊃⎕AV

10:42 PM

print'\0'

Destructible Lemon

@WheatWizard can you help me with quine making in sadflak?

Why ... does APL have those box drawing characters?

Destructible Lemon

because APL is like that

@WheatWizard if the 2+2 = five was still open this would be good for that

What was the CMC, print the null character?

@StewieGriffin I'm still up for it, you've got my specs right.

10:50 PM

@Uriel MY, 3 bytes (hex): 00 29 26

@ZacharyT It isn't really APL per se, but rather the interpreter has a special thing that it looks for function called ⎕SE.Dyalog.Out.Filter every time it wants to output something, and if that function exists, it is called with the result. Some very clever people have created this function to make multi-dimensional nested output as legible as they could.

Oh, now I remember. ]display, duh.

@ZacharyT Yeah, but Filter can do more than that. It can display the structure of tacit functions in four different ways.

Okay. (Can't believe MY actually did decent on ANYTHING)

@ZacharyT MY?

10:54 PM

MY, it's my language that I'm creating slowly.

Destructible Lemon

Sad-Flak has various six byte solutions

(Please don't judge: bitbucket.org/zacharyjtaylor/my-language/overview)

Destructible Lemon

+3 for ascii output

nevermind

@ZacharyT Is it on the grand chart?

10:55 PM

@DestructibleLemon I did

@DestructibleLemon maybe I don't know sad-flak

Destructible Lemon

yeah, I would like some tips on how to make flakoid quines

Grand Chart?

What is that?

@DestructibleLemon You can exploit the fact that braces must be balanced

Does sadflak have non-brace characters?

Destructible Lemon

also I realised that it is nontrivial to reverse the stack in this language I think

Its non-trivial in Brain-Flak

10:57 PM

A: What are the relationships between programming languages created by PPCG users

Using the format of Webgraphviz. Links to pages about the languages can be found on TIO. # non-PPCG languages are lightgrey, non-languages are white # PPCG languages are not colored for simplicity # this has the effect of making PPCG be languages with a border digraph PPCGGenealogy { node [sty...

Destructible Lemon

@WheatWizard do you have a reverse the stack program in brainflak?

@WheatWizard it's even more non-trivial in sadflak

@DestructibleLemon github.com/DJMcMayhem/Brain-Flak/wiki/Stack-Operations

Not sure about that

Destructible Lemon

wait a minute, it looks a little bit like that roll is overcomplicated

Here's a not so golfed total stack reverse. ([[]]){((({}())<{({}()<({}<({}<>)<>>)>)}{}>)<{({}()<<>({}<>)>)}{}>)}{}

Destructible Lemon

@WheatWizard you notice how you have a <...>d loop, before pushing the initial popped value?

can't do that in Sad-Flak

11:00 PM

It probably requires a different approach

@Adám I'm not ready to put it in anything like that. Language is too dang immature.

Destructible Lemon

I think a helpful tool in sad-flak is actually remembering you can use the BF approach

btw my quine does not use a stack reverse.

@ZacharyT Nah, its fine. Remember, there are no specs there, just inspiration lines.

Destructible Lemon

@WheatWizard yeah, I know

yeah, because you can't preserve values while doing control flow, that means you need to do it the bf way of decrementing and incrementing

11:02 PM

I'm implementing nilads (done), then monads (WIP), then dyads (not yet), then triads (not even close). 2*16 bytes, 6*16 bytes, 6*16 bytes, and 2*12 bytes reserved for nilads, monads, dyads, and triads.

@LeakyNun Thanks, doesn't help me any though :P, I have no idea why maximum doesn't work on tuples, seems to always return the last element

@Adnan What was Oasis inspired by?

Probably nothing.

I mean, LOOK AT IT!

Destructible Lemon

@Adám I think we need to update that grandchart

I'm so stupid. I don't even know my own language plan. 2*16 bytes reserved for triads.

11:07 PM

@DestructibleLemon Go ahead, it is community wiki for a reason.

Destructible Lemon

@Adám how to get the image?!

Who already put MY in there?

@ZacharyT I did. You can see the edit history.

@DestructibleLemon Click the link, paste the code, click the button.

Destructible Lemon

but do I zoom out and screen shot? I heard something about an svg?

@DestructibleLemon I inspect, select the SVG element, past into text doc, upload to online SVG→PNG converter, download, drop into imgur.

11:12 PM

I added 05AB1E, I need to add that to the overview.

@ArtOfCode by good i mean it won't be auto caught

Hey, what are some good tokenizers?

@Adám 05AB1E and Python

How is Oasis influenced by Python? @Adnan

Destructible Lemon

11:28 PM

ok I did it

@ZacharyT mostly by the way how Python uses lambdas

Oh. How so?

looks like Perl points to Python twice

wait, maybe not

well it's confusing i.stack.imgur.com/mqcmY.png

@ZacharyT because I like how they look

o_o

Destructible Lemon

11:33 PM

Woefully is now part of a family or something

uhm

why is the disable output cache option not showing up on tio?

@HelkaHomba one is java leading to python, other is perl to a pear tree

@StewieGriffin I did the current batch of timings. Note that one submission is at 5ms, so If anyone else makes something with similar speed, we'll need more test cases.

11:47 PM

this is better but maybe too much spacing: i.stack.imgur.com/RsphD.jpg

@HelkaHomba It doesn't hurt to have multiple

@HelkaHomba Yeah, but now we actually distinguish the lines to the right of ><>. Nice.

Wonder why some lines are crossed when they obviously don't need to be. Like Jelly→Jellyfish/TacO.

Anyone have any suggestions for complex arithmetic functions taking one argument?
