The Nineteenth Byte

Erik the Outgolfer

15:00

anyways it's kind of cheaty

trichoplax

@programmer5000 Is there a better tie breaker than bytes, since fastest-algorithm is unrelated to golf?

I'd probably prefer first to post rather than least bytes in this case

programmer5000

Ok.

trichoplax

I'm trying to think of something better than either, so it doesn't force people to golf a fastest-algorithm entry, but also allows incremental improvement rather than leaving the first to post unchallengeable

programmer5000

Could someone PLEASE undelete and reopen that

Leaky Nun

there are few music questions here....

Erik the Outgolfer

15:06

ahem 51 questions ahem

That's not actually so few anymore.

Leaky Nun

one per month is not good

Erik the Outgolfer

IMO those aren't that interesting.

Leaky Nun

I have an idea... I may make it soon

Christopher

@Dennis how do I compress the text for bubblegum?

Erik the Outgolfer

I think he uses Zopfli.

Downgoat

15:11

TIL JS can multiple inheritance

Kritixi Lithos

TIL TIO doesn't/can't output null bytes

Mayube

@KritixiLithos it's an OS limitation

Downgoat

@ASCII-only maybe we should have used Kotlin or some other real OO Lang to make VSL. (idk swift?)

Leaky Nun

@KritixiLithos it can

Downgoat

Swift we can use flex bison and Kotlin, the Java one

Kritixi Lithos

15:13

Then I can't copy the null bytes

Leaky Nun

@KritixiLithos you can't

the clipboard literally ends with a null byte

Kritixi Lithos

But I can from Vim

Leaky Nun

nvm

programmer5000

In your browser console:

copy("hi\0there")

copies hi

Leaky Nun

I'll stop pretending to be an expert

Adám

15:15

@KritixiLithos Try it online!

Christopher

How do I give bubblegum my raw deflate stream? I have a file but don't know how to do it

Kritixi Lithos

@Adám that doesn't output anything on my machine, but having just an A works

Adám

Kritixi Lithos

is that on Chrome?

Adám

@KritixiLithos Yes. On Windows.

Christopher

15:18

@Dennis I have a problem. I have a deflate stream that I opened in notepad but it contains unprintables... How to I get bubble gum to accept them on TIO?

Mistah Figgins

if you try to move the blinking bar through the program with the arrow keys (or shift + arrows) you can see that there are characters that you are moving over that you can't see

Kritixi Lithos

I'm on macOS, that must explain it

Shaggy

Brainfart: How do you escape backticks within backticks? e.g., what would I need to type to wrap arr.join`` in backticks?

Mayube

what's the easiest way to collapse a list of lists into a single list in python3?

Christopher

What is the command to get a hexdump on bash?

Mayube

15:19

hexdump

Kritixi Lithos

xxd

Leaky Nun

@Mayube is your list 2D?

Mayube

@LeakyNun no it's just a list of lists

Leaky Nun

print(sum([[1,2],[3,4]],[]))

the ,[] is important

Christopher

@KritixiLithos thanks

Mayube

15:21

@LeakyNun oh hey that works perfectly, thanks!

Christopher

So I have a deflate stream file and I need to get the hexdump but when I get it the output text is incorrect in bubblegum

arr.join`` is arr.join\`\`

Christopher

15:26

Trash it?

@programmer5000 You just got that?

Shaggy

@Mego Doesn't seem to work - it outputs arr.join\ as code, followed by 2 backticks as text.

programmer5000

Didn't know it was a badge.

Shaggy

In answer previews, at least.

programmer5000

@Christopher yes. Wow.

Mayube

man, some Project Euler challenges need like 30+ bytes of code in braingolf, while others take 2

I should add a 2 byte builtin for each project euler challenge

Anonymous

15:27

@Shaggy Oh in answers I think you need to do double backticks to escape them

Riker

yes, but it's also the sign of not being addicted

¯\_(ツ)_/¯ imma go eat something now, see ya later

Dennis

15:40

@Christopher The TIO interpreter expects an xxd-style hexdump, not a byte stream.

Christopher

@Dennis Ok I can't seem to get it to work for me :(

@Dennis gist.github.com/anonymous/d9b6ffabcde2f1001d8b5f63b3320412

I think I may not be getting the right result from compressing

Mayube

k screw it I'm adding 2 byte builtins for every project euler challenge to braingolf

because why not

Adám

@Mayube So you'll have two prefix bytes?

mbomb007

ad score is inversely related to clicks per day... codegolf.meta.stackexchange.com/ads/display/11408

@Mayube Just have a single command that takes an integer for the number of the project euler problem.

Mayube

@Adám I'm just using 2 byte printable characters, like ߹

Anonymous

15:54

@Mayube In that case you should also add a builtin for OEIS sequences

Mayube

OEIS?

mbomb007

oeis.org

Anonymous

AKA the source of many PPCG challenges

tuskiomi

Think that we can take numbers from random sequences and use them as the rules for a challenge instead of an output? We could generate infinite challenges at will.

mbomb007

Just add a builtin that takes an integer and runs the code of the PPCG answer with that ID.

Kritixi Lithos

15:57

But having too many specific builtins will make the language boring

mbomb007

The longer your language exists, the better it gets.

Erik the Outgolfer

@mbomb007 lolwut that is madness, upvotes aren't used correctly.

@KritixiLithos Jelly, 05AB1E, ...

Mayube

Erik the Outgolfer

They're not that boring it seems.

@Mayube That's not a golfing language.

Kritixi Lithos

But specific builtins

tuskiomi

15:58

Have it take all the answers and terminate when the first one is done. then, you always have the best speed, and will win all fastest-code challenges

Erik the Outgolfer

Too sad that's a standard loophole :(

mbomb007

@tuskiomi answers and questions each have different IDs.

A: Turing complete language interpreter code golf

x86 assembly (Intel syntax/MASM) 2550 bytes. Being honest here this can be golfed a good amount. I have golfed a large amount of bytes off but variable can still be golfed. However trying to golf the different names is a pain but would save only a small amount of bytes. This won't win for size ...

I think I win for size :D

tuskiomi

@EriktheOutgolfer it's a joke. running all answers would always be slower than running the fastest

mbomb007

It's irrelevant. You can't know which is the fastest. Anyways, my suggestion was to take an ID. And every answer has its own ID.

Shaggy

16:07

Anyone (else) willing to vote to undelete this question?

mbomb007

No, it's made with animations and punchcards.

@Shaggy It's a duplicate, though.

Jan Dvorak

Why override the asker's will?

mbomb007

Why bother undeleting a dupe?

Shaggy

@mbomb007 That's why I'm looking to get it undeleted, so we can discuss whether or not it is a dupe, rather than just closely related.

@JanDvorak Given how quickly it was deleted after the dupe-hammer was swung, it seemed very like a rage-deletion.

mbomb007

It's "marked as duplicate"

Shaggy

16:11

OK, fair enough, consensus seems to be that it is a dupe - I'll leave it alone, so.

Erik the Outgolfer

@mbomb007 It is a dupe, although I dunno if it should be deleted, since dupes often act as signposts. Nonetheless, it should never be reopened.

programmer5000

@Shaggy I voted, we need 1 more.

tuskiomi

Does anyone know who runs ss64.com?

programmer5000

I think it should be closed but not deleted.

@tuskiomi See whois

tuskiomi

Good idea.

Shaggy

On to my next question. For those familiar with JS Promises, is the function here an acceptable answer? I've seen one or 2 other answers take this approach but it seems to be that, as it requires an extra Promise after the function is called, then those bytes should be counted towards the total.

programmer5000

@Shaggy so it returns a promise that resolves with the output? Seems fine with me.

I don't think that should count twards the byte count.

Any .then(x=>console.log(x)) should be free.

Kritixi Lithos

Why does "(The other day) I met a bear" challenge have a reopen vote? It is a clear dupe of the rickroll challenge

Shaggy

16:25

@programmer5000 I can see an argument for that approach (not least because it would save me a few bytes on some answers!) but isn't it generally required that JS functions return or log/alert/whatever the output?

Riker

^

I'd say it's not allowed

if you want to make an i/o meta answer, I'd upvote it, but it's not allowed as of right now

programmer5000

@KritixiLithos Clear dupe? Explain.

Business Cat

I agree with Riker

Although I'll say that in what you linked there's no reason to do t=>console.log(t), you could just have console.log

Shaggy

@Riker You mean here?

mbomb007

@programmer5000 But it's already deleted. By the OP. No reason to undelete it.

Kritixi Lithos

16:32

@programmer5000 Well, the only difference, more or less, between the two is that the lyrics are slightly different.

@LeakyNun Actually, 7 bytes: ú;ru♀*i

Adám

So ⍨, being monadic, looks to its left, sees ¨, which is a monadic operator, so ¨ has a go, and takes ⍴ as argument. the derived function ⍴¨ becomes the argument to ⍨.

@LeakyNun Nope :-( on the to-do list.
