The Nineteenth Byte

Erik the Outgolfer

15:00

space and dash counts

Kritixi Lithos

but in the case of a language like sed, supplying the first -r arg counts as 1 byte (because I think you need a flag to call sed without any additional flags)

obarakon

I've heard 1, 2, and now 3. Is there a meta-post?

Kritixi Lithos

I've never heard 2

obarakon

@KritixiLithos In Martin's example under #The Catalogue, he wrote 43 + 2 (-p flag) = 45 bytes

290

Q: "Hello, World!"

So... uh... this is a bit embarrassing. But we don't have a plain "Hello, World!" challenge yet (despite having 35 variants tagged with hello-world, and counting). While this is not the most interesting code golf in the common languages, finding the shortest solution in certain esolangs can be a ...

Could I get some expert Haskell golfers to take a look at this? Every byte I take off greatly reduces my score.

Is it codegolf.meta.stackexchange.com/questions/273/…

Kritixi Lithos

@obarakon what

Wheat Wizard

@obarakon Its just the number of bytes that has to be added to the command. This can be 1, 2 or 3 depending on the conditions.

Mayube

spent 3 hours today fucking with pcaps to prove to some american SIP provider that the quality issues are on their end

fun times

obarakon

@KritixiLithos In this post Martin wrote 43 + 2 (-p flag) = 45 bytes hence the 2-bytes per initial flag example.

Mr. Xcoder

How to avoid this disturbing repetition: "Unicode Codes of the characters"?

HyperNeutrino

15:05

Uni(code)*2s

obarakon

@WheatWizard Ok, that's what I'm leaning towards. So this is in fact +2 bytes for the -P flag, right?

Mr. Xcoder

@HyperNeutrino Seriously now. I am writing a sandbox post.

HyperNeutrino

Oh okay sorry

Wheat Wizard

@obarakon Why is -P in the input?

HyperNeutrino

How about "Unicode charcodes of the characters"? That at least puts something between the repetition.

Wheat Wizard

15:06

Usually it would go in the arguments

obarakon

@WheatWizard That's where they go in Japt.

Wheat Wizard

How do you evoke this in a standard terminal?

i.e. not TIO

Mr. Xcoder

@HyperNeutrino That's better, but now we repeat both char and code, although it sounds better :P

Wheat Wizard

@Mr.Xcoder How about "Unicode points of the characters"

obarakon

@WheatWizard I don't know how to answer that, I've only used TIO and the interpreter

Mr. Xcoder

15:08

@WheatWizard Perfect, thanks

HyperNeutrino

ooh nice

Wheat Wizard

@obarakon I don't know how many bytes this is. I would consider taking it up with meta or asking the creator if there is a way to evoke this in a standard terminal environment

Mr. Xcoder

@HyperNeutrino How in the world did you achieve Mortarboard already?

HyperNeutrino

@Mr.Xcoder By posting 3 questions that got a fair amount of upvotes

obarakon

@WheatWizard Ok, thanks

Wheat Wizard

15:10

It might not even be allowed at all. IIRC extra input is not allowed, and this might be considered extra input

Mr. Xcoder

Cool @HyperNeutrino

HyperNeutrino

Output a highway: 29 upvotes yesterday, 5 today

Mr. Xcoder

Nice

HyperNeutrino

How much rep did you lose today?: 11 upvotes yesterday, 8 upvotes yesterday (but separate events because of UTC time

etc.

So I should have gotten 275 rep yesterday + assoc

75

(well actually 5800)

but I lost 75 to the cap

obarakon

@WheatWizard That would be unfortunate, I will ping the creator.

Mr. Xcoder

15:13

@HyperNeutrino NO, you have written that: "How much rep did you lose today?: 11 upvotes yesterday..."

Wheat Wizard

Could I get some expert Haskell golfers to take a look at this? Every byte I take off greatly reduces my score.

HyperNeutrino

@Mr.Xcoder oh well that was the name of a challenge lol

Mr. Xcoder

Oh, I am so dumb (again)

HyperNeutrino

Can those answers be easily or trivially modified to answer your challenge?

And also, ASCII vs UNICODE

I wouldn't CV for anything

Jim

@Mr.Xcoder Challenges about Kolmogorov complexity are popular lately

Mr. Xcoder

@HyperNeutrino Keeping in mind that one is like 10x15 and mine is like 40x75, no

HyperNeutrino

ah yes, true

Mr. Xcoder

They cannot be trivially modified.

HyperNeutrino

then it would probably not be a dupe.

@DJMcMayhem It's because of the rendering on mobile

@Downgoat How do I put multiple statements into the REPL at once?

@WheatWizard Is x!y tetration?

If so, it should be x!y=x^(x!(y-1))

Wheat Wizard

@LegionMammal978 Yeah unfortunately that costs me bytes.

LegionMammal978

@WheatWizard Then too bad, that's the definition

Wheat Wizard

I forgot that ↑ was not commutative.

LegionMammal978

Also, it should be x!1=x

Wheat Wizard

yeah, but My aim is to create the fastest growing function so I get free points for using 0

ETHproductions

16:16

@WheatWizard I was young and dumb when I created Japt and didn't know how to do anything in a terminal, so you actually can't run a Japt program directly from the terminal (You have to write a JS file that imports Japt and runs the program with the input). That's why TIO uses a custom wrapper and why flags go in the input field.

Wheat Wizard

Hm this seems like it might need a meta then

LegionMammal978

@WheatWizard ??? 2³ = 8 < 9 = 3²?

ETHproductions

Alright, I'll write one up

Wheat Wizard

@LegionMammal978 Yes? I don't see your point.

LegionMammal978

@WheatWizard I don't see where you got the idea that exponentiation was commutative

Wheat Wizard

16:19

Multiplication is commutative

addition is commutative

LegionMammal978

...by definition

ETHproductions

My personal opinion is this: generic flags only require two bytes to be added to the input, so it should only count as two bytes. Not sure whether putting them in the input affects anything

LegionMammal978

And exponentiation is the first operation not specified by the actual field

Wheat Wizard

yeah, I just didn't think about it too much

LegionMammal978

Oh well, I don't think sometimes either :p

ETHproductions

It already supports node halfway

I mean, you can use it in node

dzaima

I really should rewrite SOGLs preprocessor and execution system, but I'm too lazy :p

ETHproductions

It's just not designed for node

Downgoat

You should do in node and webpack it

ETHproductions

But it's freakin' designed to be easily integrated into the online interpreter :P

Back in the day the internal and external sides of the interpreter were one and the same

But... yeah, maybe it is time to move on

dzaima

question: should I sandbox that?

Downgoat

@ETHproductions yea that is what webpack does

You get benifits of node (multi files, modules, up to ES8 features, and still get to do in browser)

HyperNeutrino

@DJMcMayhem How exactly do you represent matrices in BrainFlak?

DJMcMayhem

Q: How to score "command-line" flags in Japt

When I first created Japt I was young and innocent, and I didn't know how to use a command line. So I created the interpreter with HTML and incorporated the JavaScript right into that. As Japt grew up, I added more features, one of which is a set of flags that slightly change the behavior of the...

A: Sandbox for Proposed Challenges

Iterate over pairs of sets Consider all possible pairs of sets of integers (can have positive, negative and zero values) A and B such that |A| = |B| = 7. Define the set T_{A,B} = {a * b | a in A, B in B}. We say that two pairs of sets X1, Y1 and X2, Y2 are equivalent if T_{X1, Y1} = cT_{X2, ...

too many proposed challenges!

Rod

@Lembik challenges are like coffee, there is never too many

Lembik

:)

DJMcMayhem

Amen, fellow coffee lover

Lembik

I suspect you are wrong on at least one of those two counts

@DJMcMayhem I agree, but my stomach doesn't.

Phoenix

My stomach may becoms relevant in the near future now that finals are over, but up to now I've been drinking all the coffee

Erik the Outgolfer

@Dennis why?

Downgoat

Question: if I am not of drinking age can I still go into a bar (I'm not going to drink or anything)

LegionMammal978

@Downgoat Probably depends on the bar/jurisdiction

Phoenix

@Downgoat Not in the United States

Downgoat

:(

LegionMammal978

Also, you have any ideas why the test is bork?

Dennis

@EriktheOutgolfer I have an acid stomach. Coffee doesn't exactly help with that.

LegionMammal978

The Node debugger is regularly unhelpful

Phoenix

@Downgoat Why do you need to go to a bar?

LegionMammal978

@Dennis I'm just imagining a stomach consisting of entirely (lining and everything) corrosive acid

Erik the Outgolfer

18:57

caret reply sucks

Dennis

@Downgoat Move to Germany. At 16 years, you're allowed to enter bars without parental supervision and drink beer.

Erik the Outgolfer

@Dennis oh...\

Dennis

@LegionMammal978 But the concentration of the acid depends on what you ingest. It gets quite uncomfortable when the concentration is too high.

Downgoat

@Dennis wait don't you guys have like autobahns where you can go at very high speeds O_o

that seem like bad idea to combine with low drinking age >__<

DJMcMayhem

@Downgoat Sometimes (for concerts I have many times)
