The Nineteenth Byte

8:06 PM

@NewMainPosts I finally came up with a challenge that levels the field between golfing and non-golfing languages a bit! \o/

Wheat Wizard

8:23 PM

@Mr.Xcoder Huh? I don't see anything different about the answer distributions.

FlipTack

Can any Python heads help me golf this?

Mr. Xcoder

@WheatWizard Huh? The only golflang solution is in MATL (inpired by MATLAB ~ Matrix Laboratory) and that's only 5 bytes away from APL

@FlipTack I am trying, will comment if I get anything good

Wheat Wizard

That's pretty standard. APL usually scores just behind the golfing languages, and MATL is usually towards the tail end of the golflangs

Mr. Xcoder

@WheatWizard MATL is usually towards the tail end of the golflangs - Not when it comes to matrices.

FlipTack

@Mr.Xcoder I tried making the function write to its argument (allowed by meta) using m[:]=[...], but it ended up as a much more confusing output format with the same bytecount

Mr. Xcoder

8:25 PM

@FlipTack Funnily enough, I just did that too

Wheat Wizard

@Mr.Xcoder These are not matrices, they are 2D lists.

Mr. Xcoder

ಠ_ಠ what are you talking about

Pavel

@WheatWizard What's the difference? I am noob

Wheat Wizard

@Pavel A matrix is a linear operator on vectors, they can be represented by a 2D array. A 2D array is a way of storing information.

Pavel

I understood the second half of that.

@WheatWizard So an arbitrary 2D array of numbers can't necessarily be used as a matrix?

Wheat Wizard

8:29 PM

No they can, in fact a 2D array of ring elements can be used as a matrix

A matrix is a function, its just a simple type of function that can be represented as a 2D array.

@LeakyNun @Riker BTW, I finally figured it out. I was calling them in the wrong order, and the function calling f() had a catch in it, but it was a silent "Catch and do nothing" so I never realized they were called in the wrong order.

Riker

ah cool

DJMcMayhem

So a() was throwing because it relied on inheriting from b()

Wheat Wizard

The input to the challenge is technically a matrix. But the challenge is not about matrices. Just like a list of integers can be interpreted as a string but that doesn't make every challenge using them about strings.

Q: Rust Golfing Crates

So, i have started creating a golfing library for Rust, as i saw some questions about it here, with some pretty good response. The usual requirement, was usually including the include statement in the byte count, and adding the library in the header of the answer. In Rust this, for me, leads to s...

I think I found a bug in Jelly: tio.run/##y0rNyan8/99Iy@f////…

FlipTack

@Mr.Xcoder If I put p>s instead of p//s, would that work?

It seems to for the test cases

DJMcMayhem

@Zacharý Looks right to me

Mr. Xcoder

@FlipTack Wait, let me wrap my head around it

DJMcMayhem

If you remove the L, you can see it gives [[2, 4, 8, 16], [2, 2, 1, 1], [2, 1, 2, 1], [2, 1, 1, 2]], which clearly has a length of 4

FlipTack

8:33 PM

Haha that's what I'm trying to do

Zacharý

Oh, it's just me being too hopped up on APL

nvm

Mr. Xcoder

@FlipTack Well if you are performing integer division, 0 will only occur if p<s.

Wait... Why p>s... Huh? What am I missing

FlipTack

So many levels of abstraction...

Mr. Xcoder

Oh got it.

yeah p>s works I think

if you notice that it's invalid, you can rapidly switch back to // :P

I think the print all(...) might be golfable

FlipTack

Hmm... position of current item > size of matrix will yield 0 (meaning the item must be 1) for the whole first row, and the first item of the second row

And the first item of the second row has to be 1 by definition of an arrowhead matrix

so it works

Mr. Xcoder

8:39 PM

@Mr.Xcoder Nope, still 85

FlipTack

What did you try and do?

Mr. Xcoder

@FlipTack Try it online!

(switched values)

@FlipTack That bitwise XOR pisses me off terribly. I tried my best to remove it but it always ends up being shortest

ಠ_ಠ

FlipTack

Same here, I must have tried about five other methods, but nothing beats bit-fiddling >:)

AdmBorkBork

8:58 PM

8-bit fiddling?

FlipTack

Ba-dum tss

AdmBorkBork

Reminds me of a dumb joke --

A drum kit falls over. Ba-dum tsh.

DJMcMayhem

@AdmBorkBork It's supposed to go Two toms and a hi-hat fall off a cliff... Ba-dum tsh!

AdmBorkBork

9:15 PM

Sure.

Zacharý

Nice one

DJMcMayhem

Here's another dumb joke:

Why did the blind man fall in the well?

Because he couldn't see that well! Ba-dum tsh!

Steven H.

I always heard it as A snake, a drum, and a sheep fall off a cliff... Baaa-drum-tsss!

AdmBorkBork

@StevenH. Relevant skit

Zacharý

Should snake and sheep be in reverse order there?

Luis Mendo

9:30 PM

@Mr.Xcoder Thanks for the edit... again :-)

Mr. Xcoder

@LuisMendo np

Luis Mendo

Funny how, even if I know perfectly well that "np" stands for "no problem", every time I see it I read it as NP

Leaky Nun

-- What happens when P = NP?
-- Well, P = 0 or N = 1

Steven H.

@Zacharý ... Ah, shoot. Yeah

Luis Mendo

@LeakyNun Even DJ's joke was better :-P

AdmBorkBork

9:34 PM

Shh, don't encourage him. ;-)

DJMcMayhem

@LuisMendo Hehe

@AdmBorkBork too late

AdmBorkBork

I know, the +3 stars was already enough.

ATaco

Seems legit

9:56 PM

Gotta say, that's one of the best ones I've seen

DJMcMayhem

@Pietu1998 Check out Saturday Breakfast Morning Cereal. It's a lot like xkcd but... stranger

Zacharý

That does look XKCDish

Pietu1998

If anyone has 5 minutes to take a look at my sandbox question feel free to. I'll post it in a few days if nothing major comes up.

Riker

10:12 PM

@DJMcMayhem smbc is the second best webcomic

I like it more than xkcd imo

Οurous

@Pietu1998 That looks like a fun one, but I can already feel the pain of dragging in random numbers into Clean for an answer xD

DJMcMayhem

@Riker I might actually agree with you there

Riker

at least, xkcd's current strips are pretty downhill

ATaco

I disagree personally.

Riker

they're definitely worse than older ones

ATaco

10:25 PM

That's very much so a matter of personal opinion, I've been enjoying the content they're pumping out recently, more so than a lot of the older ones.

Zacharý

10:40 PM

I should probably work on MY some more

Yay. I got hats and didn't do anything

Is there a page for the secret hats this year?

I want to see what the hints for the sun one are
