bai

quartata

By the way I found the PHP thing

Apr 12 at 2:38, by quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ By the way: array_reduce(range(1, $n), function($accum, $arg) { return ($accum *= $arg); }, 1)

Apr 12 at 2:42, by Downgoat

Array.prototype.slice.call(Array(n)).map(function(item) { return item + 1 }).reduce(function(accum, arg) { return accum * arg });

Cᴏɴᴏʀ O'Bʀɪᴇɴ

what is the code supposed to do?

I'm too lazy to read

quartata

factorial

Cᴏɴᴏʀ O'Bʀɪᴇɴ

and the objective is to make it look readable?

quartata

Yeah.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:03 AM

kk, gimme a sec

quartata

I know you can use a for loop but why

You shouldn't have to

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I won't.

factorial = n =>
	n <= 1 ? 1 : n * factorial(n - 1);

There, beautiful.

quartata

Recursive and ES6

Cᴏɴᴏʀ O'Bʀɪᴇɴ

So?

quartata

You shouldn't really have to use recursion...

Geobits

1:05 AM

To be fair, it is a lot more readable, and the recursion doesn't hurt it that I know.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

You were asking for which looked nicer iirc

^^ thanks

quartata

JS doesn't have tail call optimization

@CᴏɴᴏʀO'Bʀɪᴇɴ True.

Geobits

If I ever need tail call optimization for a factorial function, just shoot me. The call stack should never be very deep.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

function factorial(n){
	var acc = n < 1 ? 1 : n;
	while(n --> 1)
		acc *= n;
	return acc;
}

There, that's fast.

ES5, fast, and readable.

quartata

function factorial($n) {
  return ($n <= 1 ? 1 : $n * factorial($n - 1));
}

Recursive and PHP

quartata

Part of what I don't get is that PHP syntax and JS syntax aren't that dissimilar to be honest...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Yeah, except for the ugly money variables

quartata

That's not hating PHP then. That's hating Perl

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I never said I wasn't hating perl.

:P

People who name their variables with $ in them who aren't obfuscating deserve to be buried >:|

(jk)

quartata

$ as in s as in scalar

I swear, funny chars make sense to me...

@CᴏɴᴏʀO'Bʀɪᴇɴ What's the -->? As in n-- > 1?

Reducing is still better though :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:11 AM

@quartata Yes, it's the classic "goes to" operator :P

quartata

I suppose neither of these programs really look all that different though...

Still though, the PHP one liner is better than the JS one liner. You gotta admit :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

...

Geobits

@CᴏɴᴏʀO'Bʀɪᴇɴ I grew up with STRING$, so as ugly as they are, they aren't a huge readability issue for me :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

function factorial($n){return ($n<=1?1:$n*factorial($n-1));} JS, PHP polyglot

@Geobits That's understandable. I meant to make the point earlier that those used to a certain syntax style think it's readable.

Alex A.

I don't think $ affects readability per se, I just think it's ugly as sin.

quartata

1:14 AM

How is $a that different readability-wise from var a anyways? (At least during declaration)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@AlexA. For me, it makes my eye pause momentarily. :P

@quartata Is that what the $a does? Initializes a variable?

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ No.

(:P)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Then how is comparable to var a?

quartata

I meant readability wise.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

you only read var a once a variable, whereas you read $a every time you see the thing.

Not really comparable.

quartata

1:16 AM

Fair enough.

Geobits

Well at least you don't need syntax highlighting to find your variables >_>

<_<

Cᴏɴᴏʀ O'Bʀɪᴇɴ

which language is that? :P

quartata

So just to clarify though. In terms of non-function one liners

Array.prototype.slice.call(Array(n)).map(function(item) { return item + 1 }).reduce(function(accum, arg) { return accum * arg });

is more readable?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata ... did you just change sides?

quartata

No, I'm trying to understand your point.

There was an implicit question mark at the end

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:18 AM

Aren't you a python programmer? "Explicit is better than implicit"? :P

In ES5?

Geobits

> a program

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Or do we allow ES6

quartata

I suppose, although he showed a similar ES6 one that wasn't much better

I think he did Array(n).keys() instead of Array.prototype.slice.call(Array(n))

Cᴏɴᴏʀ O'Bʀɪᴇɴ

And you want to do it by... creating an array and reducing it over multiplication?

quartata

No. But that's the most natural way, right?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:20 AM

... no. Recursive.

Especially considering PHP has a range builtin, and JavaScript doesn't.

Geobits

IntStream.rangeClosed(2, number).reduce(1, (x, y) -> x * y)

boom

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Is this Java?

quartata

@Geobits Even that makes sense to me

@CᴏɴᴏʀO'Bʀɪᴇɴ Yeah, Java 8 though

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I like it a lot

Geobits

Honestly, I've still only played with Java 8 a bit, but what I've seen is nice enough.

orlp

1:21 AM

well that was an interesting experience

Geobits

All my "work" is done in Java 5 :o

orlp

for a sec I forgot how old I am

whether I'm 20 or 21 lol

Geobits

@orlp I think that happens more often when you triple that or more.

quartata

I forget what year it is a lot

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Soon, "Am I 60, or 65?"

Ashwin Gupta

1:23 AM

@El'endiaStarman ok, yeah alerts I'll change. Also, Idk why that missile firing sound would be the case, I'll double check my logic.

orlp

@CᴏɴᴏʀO'Bʀɪᴇɴ sorry

I should've been more specific

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@orlp what?

I'm just making a joke :P

orlp

I forgot whether I was 20 or 21 centuries

Cᴏɴᴏʀ O'Bʀɪᴇɴ

oh lol

Geobits

Well that seems understandable.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:24 AM

^

Geobits

Do you remember this battle? If so, you're more likely 21 than 20 centuries.

quartata

I just found a crushed card sleeve under my desk

rip

Cᴏɴᴏʀ O'Bʀɪᴇɴ

card?

quartata

Card sleeve

Plastic card sleeves are devices used to protect trading cards from damage, especially collectible card game cards from wear and tear and to store them. == Varieties == Thanks to the trading card industry, there developed a wide variety of protective devices, including the bulky "top-loader", a rigid plastic case with one open end (essentially a box for a single card) and the less-expensive simple "card sleeve," a card-sized envelope of clear plastic, with one end open. The term may also refer to 9-pocket pages designed to store trading cards in binders or card albums. == Development ==...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

eugh

quartata

1:38 AM

?

Having sleeves is super important

Cᴏɴᴏʀ O'Bʀɪᴇɴ

just mirroring "rip" with a different word

quartata

Oh

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Ik, I love sleeves

I got $15 bucks off of a yu-gi-oh card worth $7 because I included a sleeve >_>

quartata

Seriously?

A sleeve costs like 30 cents...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

actually

It maintained it's condition, I guess

That, or my friend was a r***rd

Downgoat

1:40 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ Chat MathJax is really messing up that message <_<

Zizouz212

Hey language!

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat haha scrubs

Geobits

Who is language?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

idk

Zizouz212

@CᴏɴᴏʀO'Bʀɪᴇɴ Language!

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:40 AM

Ah/

Zizouz212

I might not be chatting, but remember, I am always watching.

Geobits

r***rd == record?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

._. good to know

quartata

@Zizouz212 R = {ε, "that", "or", "my", "friend", "was", "a", "r***rd"}

There you go

Cᴏɴᴏʀ O'Bʀɪᴇɴ

XD

Zizouz212

1:42 AM

-_-

Downgoat

Also, if anyone cares, Downgoat's Solar System Simulator™ is now on Github.

@Downgoat Ugh.

DS3?

@Zizouz212 ಠ_ಠ

Hey. Don't give me that.

quartata

1:42 AM

@Zizouz212 It's actually pretty nice

Zizouz212

Sorry, I get really crazy when I'm tired.

And I am incredibly tired.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

You have no excuse. I've been running almost 24 hrs on 3.5 hrs of sleep

Zizouz212

Speaking of which, why am I here, I need to go back to sleep while doing homework

Geobits

Back in my day we didn't complain until at least the 30-hour mark :P

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ pfft, my server has been running 15 weeks with no sleep

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:43 AM

(Pattern="r???rd", Sort=Alphabetical)

record, regard, retard, reward, reword, ritard

@Downgoat I want to be your server >:|

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ if you can run Mac OS X server, sure.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat Give me enough money, and I can run (away with) it

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ i have 340 stacks of hay, is that enough?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

${\tiny can you read this well?}$

Zizouz212

I should get a job.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:45 AM

@Downgoat Bah! How dare you insult a dragon with a petty gift as such.

Zizouz212

Dragonz?

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ :( hay is very valued by goats

Zizouz212

But you're a downgoat

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zizouz212 ಠ🐲ಠ

@Downgoat golddddddddddddddd

Zizouz212

quartata

1:46 AM

@Zizouz212 backslash fail

Zizouz212

I find that offensive

Cᴏɴᴏʀ O'Bʀɪᴇɴ

:D I found a happy dragon emote: ^.=.^

Zizouz212

Speaking of which, that was my first emote :)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Zizouz212

That I've ever posted in my life

That doesn't count

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:47 AM

why not? :P

Zizouz212

That was the first fancy one, or it barely meets your standard

That was the first one that met your standard?

Geobits

@CᴏɴᴏʀO'Bʀɪᴇɴ I think it's spelled wynaut in this case.

Zizouz212

Wobbbbufffet.

Geobits

Pfft, you're barely evolved.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zizouz212 all emoticons are equal

@Geobits ahem racist

Zizouz212

1:49 AM

@Geobits \o/

I challenge you to a pokemon battle.

Geobits

Umm. Ok, let me get my DS.

Zizouz212

lol Pokemon was the only game I had when I was younger

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I've always played PC games

Zizouz212

@CᴏɴᴏʀO'Bʀɪᴇɴ Ha.

Geobits

@CᴏɴᴏʀO'Bʀɪᴇɴ A PC master racist then?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:51 AM

NOW I GOTTA GO DO MY HOMEWORK

@Geobits indeed?

Zizouz212

@CᴏɴᴏʀO'Bʀɪᴇɴ No.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

You have no excuse. I've been running almost 24 hrs on 3.5 hrs of sleep

I need to sleep

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ you playing superhot yet it's one of the most innovative shooters I've played in years hue hue

Zizouz212

No.

No homework.

quartata

I thought people would know the joke

Oh well

I guess the whole point is you don't know the joke unless you've played superhot

Zizouz212

1:54 AM

@quartata Clearly none of us have.

Geobits

@Zizouz212 2938-7048-4362

quartata

@Geobits oh shit

2

Zizouz212

Oh seriously? I was just joking... I have work to finish up. And I need to find my ds too

It's 10 pm here

quartata

You should really just play on Pokemon Showdown or Online though

Zizouz212

@quartata Eww

Geobits

1:55 AM

@Zizouz212 Here too. If you wanna back out, be my guest ;)

Zizouz212

Wait, @Geobits what version do you have?

quartata

@Zizouz212 Uh...?

Zizouz212

Aren't those the wii games?

quartata

No.

Geobits

@Zizouz212 OR, but nothing exclusive to it, so I can battle X/Y just fine.

quartata

1:55 AM

They're the battle simulators Smogon uses

Zizouz212

@Geobits Oh. You're new school.

I'm old school.

quartata

i.e competitive play

Zizouz212

HGSS, DPPt, BW

Geobits

@Zizouz212 Well, I have pretty much all of them. I've moved most of my fighters to the newest generation though.

Zizouz212

and Ruby and Sapphire, and Emerald - on the game boy :)

Geobits

1:56 AM

Sure, I just played through Yellow again recently.

quartata

played crystal again recently

Zizouz212

Yeah, XY looks cool, but I don't have the new ds. Still with a DS lite :)

Geobits

It does have some nice additions. I'm not a huge fan of the whole mega thing, but some other things are nice.

Zizouz212

Yeah, some of the megas kind of scare me

quartata

Megas and Fairy totally and completely changed the meta which is why I quit keeping track of competitive Pokemon

Zizouz212

1:58 AM

Oh yeah. The fairy type

I've never experienced that...

Geobits

Yea, I haven't been into competitive much. I just get bored and beat down randos at the battle spot from time to time.

Zizouz212

Me neither.

Favourite pokemon. Go!

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata ??

Downgoat

sohuld cheddar have map literals?

orlp

if you were to be sorted into a house in harry potter, which would it be?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

1:59 AM

@Zizouz212 lucario

orlp

I'd almost surely be ravenclaw

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ Inside joke I suppose

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@orlp ravenclaw

Zizouz212

@CᴏɴᴏʀO'Bʀɪᴇɴ How dare you!

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata o-o

quartata

1:59 AM

@Downgoat yes

Geobits

@Zizouz212 It's not the best fighter, but I still carry my shiny Umbreon with me everywhere.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zizouz212 wat?
