can some tell me what the fuck is wrong with my challenge!?

@Doᴡɴɢᴏᴀᴛ do it.

which one?

@Seadrus probably for being to easy

Nothing. It's just simple, and haters gonna hate.

@mınxomaτ ...

3:07 AM

oh shit I had @Doᴡɴɢᴏᴀᴛ ignored

@Doᴡɴɢᴏᴀᴛ Why not?

@Seadrus D:

i dunno why D:

@mınxomaτ eh, what could go wrong?

@Doᴡɴɢᴏᴀᴛ xactly

@ETHproductions ooo I like

Support for arbitrary angles?

Maybe, I'll think about it

gtg for now

I should do it from a different account just in case I ever need to contact nasa customer support

@Seadrus I think its fine, but as others have said, it is quite trivial for math-based languages. Other than that I see no problem.

@GamrCorps oh oky

3:10 AM

@ETHproductions bye!

@Doᴡɴɢᴏᴀᴛ No, too alarmy. There are grounds for arrest there.

@Doᴡɴɢᴏᴀᴛ ಠ_ಠ

@CᴏɴᴏʀO'Bʀɪᴇɴ how so

If you're in America, you can be arrested for causing terror.

@CᴏɴᴏʀO'Bʀɪᴇɴ D: "Requesting NASA Engineer Assistance?"

@CᴏɴᴏʀO'Bʀɪᴇɴ I don't think "URGENT" in all caps as an email subject counts as causing terror

@Doᴡɴɢᴏᴀᴛ That sounds better. Maybe, "Requiring the expertise of a NASA Engineer"?

@Doᴡɴɢᴏᴀᴛ It depends on who you're emailing.

3:15 AM

why are we contacting NASA

@ZachGates because we need the expertise of a NASA Engineer

yeah: "on golfing code"

@Doᴡɴɢᴏᴀᴛ well yeah I inferred that

@CᴏɴᴏʀO'Bʀɪᴇɴ does JS map flatten the resulting array?

@quartata no

3:29 AM

@quartata It shouldn't why?

@quartata It shouldn't when?

Because Perl map does

That's weird

Do you want that to happen?

in this case no

3:31 AM

@quartata I'd say it depends on how you use it.

okay

Hold up, now that I think about it, could you give me an example of the code you're trying to test?

I just mean if you map a function that returns an array would the result be a 2D or a 1D array

I don't have any specific code yet

\o/ dominated a team of bots

congrations you done it

3:40 AM

*congration

congrations*

oh

hey quick question guys

ye

How do I find the smallest g so that ng+A | T?

Do you care about time complexity?

3:44 AM

I just need the answer for the general form

Math question

feersum

You would use the extended gcd algorithm.

Oh I thought you wanted an algo :P

feersum

It doesn't have some nice closed form.

darn

What if T is constant?

ah nevermind

What does the expression ng+A | T even mean?

3:46 AM

n times g plus A divides T

T divisible by ng+a

Oh

ninjad

function extended_gcd(a, b)
    s := 0;    old_s := 1
    t := 1;    old_t := 0
    r := b;    old_r := a
    while r ≠ 0
        quotient := old_r div r
        (old_r, r) := (r, old_r - quotient * r)
        (old_s, s) := (s, old_s - quotient * s)
        (old_t, t) := (t, old_t - quotient * t)
    output "Bézout coefficients:", (old_s, old_t)
    output "greatest common divisor:", old_r
    output "quotients by the gcd:", (t, s)

I thought it was code in some weird esolang

3:47 AM

Wikipedia pseudo code ^^

What is this in the context of?

Oh, I was about to praise you for finally learning to indent with spaces

hahaha I know how to but its just slower

I use spaces when I code in notepad

How is it slower?

4 keys versus one

3:48 AM

@AlexA. I thought you could math

Any decent editor/IDE inserts spaces when you press the tab key

Extended GCD? Pssh, ESMin already has that.

@AlexA. Then what's the point?

@quartata I can, I just didn't recognize that as math.

ok

3:49 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ You have spaces in your source rather than tab literals.

first person to find a language in which ng+A|T does something interesting gets a cookie proportional to the interestingness of their find

@AlexA. There's nothing inherently better.

Yes there is

Besides, you can set the tabulators to whatever width you please.

@CᴏɴᴏʀO'Bʀɪᴇɴ -1 interestingness is subjective

@Doorknob You're needed

3:49 AM

what?

@ՊՓԼՃՐՊՃՈԲՍԼ +1 cuz y knot

We must explain why spaces are objectively superior to having tabs in your code.

oh

What are you trying to implement with this?

@CᴏɴᴏʀO'Bʀɪᴇɴ I must cut knot

3:50 AM

@quartata A way to generate constants

the gs2 answer should be 17 bytes but it is missing the read-num byte i'll fix it later

I'll post that thing on meta later @AlexA.

Okay

and yay golden angle

That shoud cover all the pings

4:01 AM

@quartata Why is that starred? Is this some sort of humorous reference that I don't get?

2

idk

Just curious how did you get a reply from SE so fast?

And have you talked with a CM about the question upvotes?

@quartata Kind of. They said be patient.

@quartata I have a special way to talk to SE.

@quartata More like golden rectangle, amirite?

I finally figured out a decent way to mimic a comprehension in R. sapply(<list>, function(<item>) <do something with item>)

@CᴏɴᴏʀO'Bʀɪᴇɴ I wonder, which real language is that most similar to?

@AlexA. I've also made progress on my whole "use university lab computers to form a cluster"

4:13 AM

Nice!

Thomas Kwa

@ՊՓԼՃՐՊՃՈԲՍԼ if you're going for char count anyway, why don't you use all the unicode characters and have all 1 byte builtins for math and stuff?

Any progress on your social network?

By progress, I mean I totally figured out how to do it.

@AlexA. The only social network I truly need is in the physical world.

(that means no)

Haha that was a very elegant way to phrase it

@ThomasKwa Too lazy :P

Besides, I use 1-char aliases for visually intuitive symbols.

But here's the problem: there's only so many viewable Unicode chars that are visual at the same time.

4:17 AM

I still haven't come up with a real use of high-performance computing yet.

Example: How are you supposed to represent a function for Catalan numbers using one Unicode symbol?

🐱

Wow

That's 4 bytes tho

Even for me, that's overkill

haha

Oh yeah, I'm pretty sure that's actually 2 chars

4:22 AM

bytes

🆑 for "catalan"

I still like the cat :P

Quill

@mınxomaτ All emojis are 2 chars

@ՊՓԼՃՐՊՃՈԲՍԼ bytes, not chars

No, chars

🐱 is a single character

🐱 is a single character

mothereff.in/byte-counter#%F0%9F%90%B1

feersum

Maybe @ՊՓԼՃՐՊՃՈԲՍԼ is confused because they are 2 16-bit chunks in UTF-16.

@ՊՓԼՃՐՊՃՈԲՍԼ No, 1 char.

@ՊՓԼՃՐՊՃՈԲՍԼ Also, most emojis are 1 char: fileformat.info/info/emoji/browsertest.htm

4:30 AM

Oh wait nvm

My char counter is off

Time to fix!

The "dancer" ( 💃 ) just looks very startled.

@ՊՓԼՃՐՊՃՈԲՍԼ Does ESMin also have canvas? I just noticed it on the interpreter :P

damn this is like a 4 way war between the JSGLs to implement the most exotic features

@quartata Yeah

Inspired by Jolf

Is it a turtle or different?

@quartata It's turtlewax right now.

@quartata I can argue that ESMin is the least like Javascript

4:35 AM

I agree

I'm still looking for a more golf-friendly canvas lib, but to no avail.

@quartata There are only two categories that any given thing can fall into: "turtle" and "different."

How do you compress a string in Pyth?

@AlexA. "What's that?" "Not a turtle."

@Doorknob "What's that?" "Different."

4:40 AM

paperjs.org looks amazing, but not golfable enough

@ՊՓԼՃՐՊՃՈԲՍԼ Why not just golf it yourself?

Because the syntax is too expensive...

Too many objects to alias down.

You could create your own functions like: function Z(x,y,w,h){new Rectangle(new Point(x,y), new Size(w,h)}

Meh.

That is already a thing: fillRect

I agree though that turtlewax isn't perfect

4:45 AM

@ՊՓԼՃՐՊՃՈԲՍԼ maybe write your own? It's not that difficult afaik

Something SVG would be cool

I was making one for TeaScript...

Then it became this

@Doᴡɴɢᴏᴀᴛ Oh yeah, I could...

@Doᴡɴɢᴏᴀᴛ This is the JSGL war thing I'm talking about :P

@quartata I wouldn't call it a war - it's more of a revolution.

Or friendly competition.

4:47 AM

@ՊՓԼՃՐՊՃՈԲՍԼ Or competition

nuclear war

It's pretty friendly.

Hey I'm not saying it's a bad thing

But you guys are starting to reach Mathematica levels of stuff

@quartata Oh that's just a side effect of math.js (on my part)

Someone needs to make a golfing-Mathematica

4:51 AM

@Doᴡɴɢᴏᴀᴛ That would end in disaster.

Glorious disaster, but disaster nonetheless.

@ՊՓԼՃՐՊՃՈԲՍԼ yeah, it would have 1-char builtins for everything :\

@Doᴡɴɢᴏᴀᴛ It would be worse than even ESMin, I'm guessing.

(Hope not, but probably).

@ՊՓԼՃՐՊՃՈԲՍԼ Custom encoding?

maybe?

@ՊՓԼՃՐՊՃՈԲՍԼ I didn't mean math specifically. Mathematica has all kinds of crazy junk

@quartata s/crazy/ludicrous/g

4:54 AM

5,000+ builtins

@quartata Oh yeah then that's basically a side effect of every library I've been using for ESMin.

@Doᴡɴɢᴏᴀᴛ That actually might help.

I would make one, but I don't know Mathematica very well

I guess ESMin is what Mathematica would be if it was a golfing language...

You should really make a custom encoding

@ՊՓԼՃՐՊՃՈԲՍԼ I think you just enter what you want to do in camel case and it works

@Doᴡɴɢᴏᴀᴛ Oic

Can ESMin do MortalityData[

If not it's not Mathematica yet :P

@quartata Nope

It could with some URL references and stuff

4:58 AM

A goat needs to be superimposed onto my avatar. It will never be complete without it...

I'm considering making another JSGL.

It's going to be ESMin without all the mistakes I made at the beginning.

@ՊՓԼՃՐՊՃՈԲՍԼ I think the community has had their fair share of JSGLs

@Doᴡɴɢᴏᴀᴛ I think I should add some features that make ESMin no longer a JSGL.

So far, I've got copy-paste, compression/obfuscation, direct eval-replace, etc. which make ESMin self-modifying, but that's about it.

There must be more self-modification.

@ՊՓԼՃՐՊՃՈԲՍԼ copy-paste?

You use ⟮ ⟯ to copy certain pieces of code, then reference them using Ⅰ Ⅱ Ⅲ or ᶈ

It's a great alternative to variable declaration

See molarmanful.github.io/ESMin/…

5:09 AM

^ downgoat with a down goat

And its upside down oic

I could also mask the -1 inside a goat

should I make the -1 upside down?

No what you have now seems good

Although you could make the goat become the red and have the -1 inside the goat

make the goat taller or the one smaller

The top is cut off

5:20 AM

the hell is happening in here

down goats

and -1s

and JSGLs

@quartata It's a race between the JSGs to distance themselves from JS as much as possible

@Mego Because why not?

there ya go

It is incredibly difficult putting downvotes in downgoats

"Down, goat!"

that one looks better

@Downgoat One more opportunity to test my tracer. Here, have a high quality downgoat

@mınxomaτ dat quality tho

@Cyoce It's a stupid one in the context of byte-scoring.

There was a question that allowed scoring in chars, that was nice.

But that almost never happens :(

Dennis

6:04 AM

Scoring by characters used to be the default.

I think Sclipting took care of that.

@ՊՓԼՃՐՊՃՈԲՍԼ was there a reason for ESMin being unicode-y?

@Dennis Hehe

@Downgoat That was back when I thought 1 char = 1 byte

And I looked at a Unicode table and picked out visually intuitive symbols.

And then I posted an answer and learned the hard truth.

It was a brutal one.

@ՊՓԼՃՐՊՃՈԲՍԼ :\

Yeah, I thought it looked cool (it does)

but byte count? um...

Y'know, ESMin could really win a lot of challenges scored in chars.

@ՊՓԼՃՐՊՃՈԲՍԼ how many individual unicode characters does ESMin use?

6:07 AM

~700

maybe more

@ՊՓԼՃՐՊՃՈԲՍԼ oh, then a custom encoding won't cut it

No, I just have to define 2-byte commands.

Along with 1-byte commands.

But that would be a pain to implement afaik

I'm not a unicode expert though

true

That's why I've been putting it off

No, it isn't.

But ESMin changes way too fast.

I retract my previous statement

I'm savoring that moment before the leaderboard regex is fixed.

@ՊՓԼՃՐՊՃՈԲՍԼ what's the difference between interpreter.js and interpreter2.js in the ESmin github?

interpreter.js is ESMin 1, but interpreter2.js is ESMin 2

there is an extra 2 in the name

6:13 AM

ESMin 2 is more stable

okay

Better features too

more stable.. like it has less chances of causing a black hole than ESMin 1?

Yes

got it

6:14 AM

It'll only cause a neutron star

gonna use ESMin 1 then

@Optimizer You could cause a black and white hole if you use v1 and v2 at the same time

Or even a neutral black hole

(Is that even possible?)

I am not taking that big fo a risk

haha

anyway I'll be going now. Bai
