RIP stars, the sky is a bit darker now

Also, since single stars are weighted really low, I'm sure it'll be back to normal in an hour or so

Cat Wizard

I mean it's not like I really cared to see those other things. Somebody might but I don't

Erik the Outgolfer

@DJMcMayhem yeah I don't think so

Riker

almost done with running the code on /usr/dict/share/words

er, share dict

dzaima

my horrible APL code gave TROWELLING. Didn't save how it got there though

Cat Wizard

20:05

trowelling -> towelling is the longest chain I can make

I have no idea how it found a chain.

dzaima

@CatWizard yay so my apl probably works

Cat Wizard

I'd go with probably not.

Oh trowelling -> towelling -> toweling

Conor O'Brien

@CatWizard if the programs weren't unique would it trivialize the problem?

Cat Wizard

Not in some languages.

Theo

Anyone know how to check if words exist on repl.it

Cat Wizard

20:10

@ConorO'Brien chat.stackexchange.com/transcript/message/45442945#45442945

Conor O'Brien

ah

I think it'd be better if you penalized non-unique programs but still allowed them. I don't see this problem being competing in convention langauges

Cat Wizard

Your probably correct

Theo

Pretty sure something like this should find all words if I had a reliable way to check if words existed: repl.it/@Theodorlukin/MeaslyDeliciousTelecommunications

Cat Wizard

I'll sandbox it and think it over a little more.

Conor O'Brien

maybe "you gain 1 point for each byte, and an extra for each duplicated byte" so "111" is scored 1 + 2 + 3 = 6

Adám

20:13

@dzaima May we see the code?

Riker

we = adam

Cat Wizard

@ConorO'Brien Wouldn't you want to duplicate bytes then?

Riker

since i think anybody else except maybe conor knows apl

Conor O'Brien

code golf

so more points = blergh

Cat Wizard

Oh well then 1 byte solutions are going to dominate

Conor O'Brien

20:14

hm

Cat Wizard

I mean it's very easy to get 1 byte that errors

Conor O'Brien

maybe "-1 point for each duplicate character" and maximize

Erik the Outgolfer

Python, 0 bytes:

Conor O'Brien

@Riker I know J and by extension I know how to write almost not awful APL

Cat Wizard

@EriktheOutgolfer That doesn't error

Zacharý

20:15

@Riker And me, I was just polyglotting some more

Erik the Outgolfer

C, 0 bytes:

it's not like you can remove any substring, is it?

Cat Wizard

@ConorO'Brien Yeah, or maybe just the number of unique bytes.

Conor O'Brien

that could be nice

Adám

@Riker hey EriktheOutgolfer ngn Zacharý Bubbler and LeakyNun are in the room too.

Conor O'Brien

but then that encourages dead code

Pavel

20:15

@EriktheOutgolfer Uh

/usr/lib/gcc/x86_64-redhat-linux/8/../../../../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status

Erik the Outgolfer

it's supposed to error

Pavel

But Python 0 bytes doesn't error

Cat Wizard

@ConorO'Brien What exactly do you mean by that?

Erik the Outgolfer

yeah, that's invalid

Pavel

Ah

dzaima

20:16

@Adám the main thing of finding valid extensions of a word is this, the actual searching I did separately. Warning: ugly & very very slow

Cat Wizard

Man I hate that I can't edit self deleted questions.

Conor O'Brien

@CatWizard idk, it seems like I'd be able to make a program that errors which has a literal in it and stuff it full of useless characters. I don't have an example so I don't know if its a problem

Cat Wizard

@ConorO'Brien Well removing any part of the literal would need to make it work.

Erik the Outgolfer

@Adám just keeping track of who has been in the orchard? :p

Adám

@EriktheOutgolfer Not has been in, rather who I've seen writing APL.

Cat Wizard

20:18

I have to think about this for a while

Is there anyway to view the source on a question?

Adám

@CatWizard edit

Cat Wizard

Cat Wizard

@ConorO'Brien What about number of bytes that appear exactly once?

Conor O'Brien

20:21

@CatWizard that could work...

Cat Wizard

APL and QBasic would trivially score 9 points.

Adám

@Pavel He's OK. — Which is why he has decided to take up the clarinet…

That's my favorite kind of thing to listen to :P

DLosc

@EriktheOutgolfer Well, yeah. Of course Amazon and iTunes expect you to buy the album in order to listen to it. :P I expect that's why the (free) YouTube versions are blocked. Frankly, I'm still surprised there's so many albums available for free on YouTube (in the US, anyway).

Erik the Outgolfer

it's theoretically illegal to download YouTube videos like that, but everybody does it :P

Pavel

I pretty much only listen to electro. Although recently I discovered I sometimes like listening to AC/DC.

caird coinheringaahing

@Pavel Whatever shows up in my playlist. Titanium at the moment

DLosc

@EriktheOutgolfer I don't know how to download a YouTube video, but when I want music at work I just open a YouTube tab. Finding Nemo soundtrack is one of my top choices. ^_^

Erik the Outgolfer

DLosc

@DJMcMayhem I was always more of a Steven Curtis Chapman guy, but lately I've been finding Ortega more relaxing--good when life is stressful.

caird coinheringaahing

@EriktheOutgolfer Don't most people just use the countless websites that do it for you? That's what I do

Erik the Outgolfer

eh

Mr. Xcoder

I use free spotify because it doesn't let me listen to the same song thousands of times, which I'd otherwise do :P

caird coinheringaahing

@Mr.Xcoder Just create a playlist with a single song and play on repeat

Mr. Xcoder

20:50

Yeah but the point is not to do that :P

Pavel

I pay for spotify because I'm 16, make 15$/hour, come from an affluent family, and have nothing better to spend my money on.

caird coinheringaahing

I get my parents to pay for a family account, which only me and my sister use

Mr. Xcoder

That's what you get... for playing PUBG and golfing Jelly at the same time

@Pavel A little late but I'm listening to People who can eat people are the luckiest people in the world. Which is excellent if you have not heard it before.

Mr. Xcoder

TFW everyone else around you seems to know how to write polyglots and quines :P

DJMcMayhem

@Mr.Xcoder u wot?

I don't think I have the mental capacity to do either one of those things, much less both at the same time

Pavel

@CatWizard I'm going to have to disagree with you there

That is decidedly not excellent

caird coinheringaahing

It's... odd, but not terrible

quartata

Quines are actually not very tricky

Mr. Xcoder

20:57

@DJMcMayhem Well I've failed miserably at Jelly but at least I got the Winner Winner Chicken Dinner \o/ :P

Zacharý

Neither are polyglots... depending on how insane they are

Cat Wizard

@Pavel It's definitely in my top two favorite albums.

quartata

Polyglots are difficult for me, if only because it takes a lot of trial and error

caird coinheringaahing

Conor O'Brien

@quartata yeah, you never know what language they'll be speaking in

quartata

20:58

caird coinheringaahing

That's a very weird reaction to burning hair

Pavel

I don't like writing code where how your code looks matters
That includes golfing actually
I just write ungolfed code then grudgingly remove whitespace

Zacharý

@Mr.Xcoder I'm doing that while I can: I'm no stasoid nor chance!

Mr. Xcoder

@quartata @Zacharý >____> That doesn't really make me feel better :(

quartata

@cairdcoinheringaahing makes sense to me..if yuor hair is on fire then clearly something prety cool is happening

it;s all in The How...

caird coinheringaahing

@quartata I fail to see how that means something cool is happening

This is why I follow quartata on twitter

@Pavel Wut are the other "cool things"?

caird coinheringaahing

@Pavel Only if I'm not in or attached to that fire :P

quartata

@cairdcoinheringaahing im pretty sure this sort of thing is covered under the "cops can gas your house with Radon'""' laws i was talking about earlier

being semantic about the word cool...

Pavel

@Zacharý Lots of stuff

Most things, actually.

caird coinheringaahing

@Zacharý Blowing things up

Zacharý

21:02

@Pavel Was just making sure that S⊂S is false to you.

Pavel

S is a subset of S

quartata

@Mr.Xcoder the secret to quines is getting the quote marks in the string you see

Mr. Xcoder

Aha, everything is crystal clear now :P

I guess I'll just stick to golfing...

quartata

@ConorO'Brien very few make the cut unfortunatelly., it takes extreme loyalty

Pavel

Quartata is actually super smart but you can never tell if he's saying something serious

Zacharý

21:03

@Mr.Xcoder Why the "à"

caird coinheringaahing

Hehe, watching the Pokemon credits at the end of the game are great. You get about 100 Japanese names, then one "John Smith" at the end of each development team :P

Mr. Xcoder

Typo

quartata

@Pavel im serious about the quines

think about it

Erik the Outgolfer

@Pavel not a proper subset though ;)

quartata

thats why you use %r in the python quine

Pavel

21:04

Good thing ⊂ means subset and not proper subset

Zacharý

@EriktheOutgolfer exactly...

Mr. Xcoder

How can we be sure that he's being serious when they say they're serious tho /mindblown

quartata

you get the quote marks

Zacharý

@Pavel It's like 0∊N

Erik the Outgolfer

@Pavel uh, it means proper subset

quartata

21:05

@Mr.Xcoder because i have proof

Zacharý

@EriktheOutgolfer It's like 0 being a natural number: sometimes it is, sometimes it isn't...

Pavel

@EriktheOutgolfer The unicode charater is called SUBSET OF.

Conor O'Brien

@quartata ah

caird coinheringaahing

⊆ is subset

rapidtables.com/math/symbols/Set_Symbols.html

Zacharý

@Pavel Unicode also f**ked up directions, so I wouldn't trust it

Mr. Xcoder

21:06

0 is not positive by definition, and ⊂ is defined as strict subset.

quartata

it is known, for instance, that Pavel would let me eat his own eardrum if i was on my deathbed

Pavel

Oh actually yeah I'm bad

quartata

thats the level of commitment that is needed

caird coinheringaahing

@quartata Huh? I may need some backstory for that...

Zacharý

@Adám, and THAT is why I don't want ⊂⊆⊃⊇ to have their set functionalities in RAD

quartata

@cairdcoinheringaahing its pretty much as simple as it says

Q: Find the minimum cost matching between arrays of integers

Consider two sorted arrays of integers \$X\$ and \$Y\$ of size \$m\$ and \$n\$ respectively with \$m < n\$. For example \$ X = (1,4)\$, \$Y = (2,10,11)\$. We say that a matching is some way of pairing each element of \$X\$ with an element of \$Y\$ in such a way that no two elements of \$X\$ are...

@ConorO'Brien Do you know where that comes from originally?

Conor O'Brien

no idea

Anush

I am always temped to put a complexity restriction on but this code-golf question has no such restrictions! :)

quartata

You could have done fastest-code

@Anush why?

@ConorO'Brien ughhh..... it's using transparency

Conor O'Brien

oh that's weird

quartata

I can't view it in Chrome in a separate tab, because the background is black

Erik the Outgolfer

I just use mspaint lol

quartata

Everything that is white in that picture is actually transparent

Anush

@quartata yes but I don't really understand how to pose fastest-code questions. I mean it seems you need good test data and to run everyone's code

quartata

pretty much, yeah

Anush

21:19

what could suitable test data be for this question?

quartata

You should have some test data for code-golf anyways

erm

Anush

I would love to make a fastest code version

sure but the test data for code-golf can be tiny

Cat Wizard

@quartata If I follow you on twitter can you give me your word you will try not to die? I need my eardrums.

Anush

whereas for fastest code it has to be big

caird coinheringaahing

@Anush A bit of advice: A few restricted-complexity posts are fine, but making every single one of your posts into restricted complexity means that less people will compete in all of them. Pure code golf is much preferred.

Erik the Outgolfer

21:20

same is true for me as well ^^^

@CatWizard well i can't actually die, its just hypothetical

Cat Wizard

How does one move a bank account? Aren't they, like, metaphysical?

@Mr.Xcoder When you added the % sign you divided by 100.

caird coinheringaahing

@CatWizard Withdraw the money from account X, and deposit it all in Y.

Cat Wizard

21:39

Oh like changing a bank account.

quartata

no, to a different bank

Cat Wizard

Ok so one bank takes the account and gives it to the other but keeps the money?

caird coinheringaahing

No, the money is transferred

Cat Wizard

With or without the account?

quartata

they keep my money marked and in a special quarantine, its got norovirus on it

so they have to physically move it... its kinda complicated

caird coinheringaahing

21:41

So, a new account is opened in bank B and the money in the account in bank A is moved into the new account AFAIK

Cat Wizard

And what do they do with the old account? Do they just throw it away?

caird coinheringaahing

Presumably they close it down

quartata

in this case they have to burn it because fof the contagion...

Cat Wizard

I guess they could probably reuse it.

quartata

i trust they know how to do that safely

Cat Wizard

21:42

But they would have to clean it first.

a - ~-b

I know.

You can't write an expression in two variables using only unary operators. [citation needed]

Erik the Outgolfer

what about (a, b)? it doesn't even have operators...

@DLosc You can in Haskell

Erik the Outgolfer

in Haskell pretty much every operator is unary

Zacharý

That's more like currying, isn't it?

Erik the Outgolfer

and those which only contain symbols can simply be parenthesized

Cat Wizard

@Zacharý No, I literally just used the words unary and operators to represent the variables.

It's really dumb

Zacharý

Didn't see the top part

Does Bash remove null bytes from strings?

^Anyone here good at bash?

Pavel

@Zacharý It's a bit weird but basically yes.

pavel@PavelLaptop:~> foo="$(echo -e "\0")"                                                                              -bash: warning: command substitution: ignored null byte in input                                                        pavel@PavelLaptop:~> if [[ "$foo" -eq "" ]]; then echo equal; fi                                                        equal

Zacharý

Is there anyway to avoid it?

Pavel

No. Bash strings can never contain null bytes, since program arguments can't contain null bytes.

That's the other thing, even if you could put null bytes in bash strings there would be no point.

Zacharý

@FreezePhoenix: regarding the comment of NieDzejkob ("are trailing newlines allowed"), I would say yes, as there are languages that cannot output without the trailing newline, and the Vim answer all the way back at #6 has had a trailing newline.
