The Nineteenth Byte

@Doorknob冰 So something like this:

XD

->a{x,y=a.split(?/).map(&:chars);eval a+".0=="+(x-y).join+?/+(y-x).join+".0"}

That's 77 bytes now 0.0

Thanks

@quartata looks good

10:01 PM

@MartinBüttner If it makes you feel any better, I can't think of any other ways to shorten what I currently have so if you can get below 96 you'll still beat me.

which lang?

Ruby

nice

@quartata kill the parens after map as well

@Doorknob冰 You can do .map&:chars? o_O

@AlexA. no, .map &:chars;

o

@RikerW IIRC that message holds the record across chat.SE and chat.meta.SE; chat.SO still has one at 75 stars

I wish GitHub repos oneboxed so that I could link to o.c every time I said "Oh"

10:04 PM

@Doorknob冰 golfed 19 bytes off in the Nineteenth Byte

Martin Büttner

@Dennis How about a challenge? The first one not to rep cap in 2016 loses. (With the mortarboard definition of rep cap.)

Interesting

@quartata \o/

Now if only floating point division was default in Ruby...

@MartinBüttner So you both have to rep cap every day and the first day one of you doesn't rep cap, that person loses?

10:05 PM

80 rep from mortarboard

@quartata You don't need to append .0 twice

only once

I tried it that way and I did

Martin Büttner

@AlexA. that's the idea.

I'm 97 rep away, and we only have two hours left :P

@quartata weird; you shouldn't

The first fraction would divide fine but the second one would divide like an integer, resulting in something like 0.blahblahblah == 0

10:06 PM

@MartinBüttner :D I hope Dennis accepts your challenge!

Oh, right

Martin Büttner

Oh, Dennis only has 25 today. I guess that means he won't.

@quartata then you only need the last .0, no?

I tried it both ways

huh

irb(main):001:0> 5.0 == 5
=> true

10:06 PM

Right...

Try this: 1/4.0 == 1/4

@MartinBüttner He might still, so long as he doesn't mind losing immediately after starting. :P That or gains +175 rep in the next 2 hours.

@quartata well, 1/4 is 0

Right. I need the .0 so that it doesn't int divide

But you're only doing one division

right?

No, two

10:07 PM

I think it is definetly possible for him to gain 175 rep in 2 hours, maybe 2 minutes

6 mins ago, by quartata

->a{x,y=a.split(?/).map(&:chars);eval a+".0=="+(x-y).join+?/+(y-x).join+".0"}

The eval compares the original fraction to new fraction

Look at it again

ohhh, a is a fraction

Yea

right okay

10:08 PM

Anyways I'm pretty damn happy with 76 bytes

Much shorter than I expected

Nice work :)

would not eval'ing the second part be shorter

Someone should make a Java golfing language.

Eh?

@Doorknob冰 I'm not sure

^^ Already in the process

10:09 PM

@Doorknob冰 I doubt it. It would mean a lot of casting

Well, CJam is implemented in Java, does that count?

@CᴏɴᴏʀO'Bʀɪᴇɴ I started work on one a long time ago and gave up

@GamrCorps Tell me more?

@quartata Shame.

Java can't evaluate itself very easily

@quartata Really?

compile a new program inside java?

10:09 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ Since I joined I have been working on it. Shall I finish it?

It requires insane amounts of effort

You have to parse it yourself and use reflection

^

@GamrCorps 'Twould be nice.

Ok, I'm on it

@AlexA. Yeah, I felt like putting effort into something today.

Very out of character for me.

10:10 PM

@quartata There's a thing called Compiler and ClassLoader classes that can do it...?

@FlagAsSpam Nope

@quartata Really? You can't just put the program into a string, save it as a file, and compile it?

What about writeToFile("/tmp/a.java", code); system("javac /tmp/a.java; /tmp/a.out or whatever")?

yeah

Sure...

But then you have to reload the class loader and it's not very elegant

Plus then you can't evaluate tiny expressions without wrapping it in a class

@AlexA. meta.stackexchange.com/questions/177532/…

10:11 PM

@Doorknob冰 This is what I meant. :P You can use the compiler and ClassLoader classes

It's just better not to go into that realm

Now Groovy can evaluate itself very easily

@quartata You might be able to use the JS eval.

Eval.me(

@FlagAsSpam Not quite the same

Not quite, but it works for simple stuff.

A: What's $-operator supposed to mean for a string?

13

It's an interpolated string literal, introduced in C# 6. It's broadly equivalent to: eventStream.ReceiveJoke += joke => Console.WriteLine(string.Format("Pretty nice joke: {0}, Thanks!!!", joke)); The compiler looks for braces within any string literal introduced with $, and applies stri...

10:15 PM

I wish I had this many up votes.

18563

You are a victim of branch prediction fail. What is Branch Prediction? Consider a railroad junction: Image by Mecanismo, via Wikimedia Commons. Used under the CC-By-SA 3.0 license. Now for the sake of argument, suppose this is back in the 1800s - before long distance or radio communication...

@FlagAsSpam especially when when (hopefully) change to the +10 on questions

Nah. I don't have enough questions.

We should bump the answers to 20 rep each. :D

200 rep for every upvote

:DDDDD

Aleph 0 for every upvote

10:17 PM

Votes don't matter, everyone starts with 100k rep

As always, ESMin wins in char count but dies in byte count. codegolf.stackexchange.com/a/68359/41247

It was doing so well, too. ;(

@FlagAsSpam Half of that user's rep comes from that answer

I propose that for now on, all reputation from upvotes comes from Dennis' infinite well of reputation.

\o/

@ןnɟuɐɯɹɐןoɯ You really should implement a custom code page for ESMin.

10:18 PM

i wish i could start a bounty with rep from a different site. i'd gladly give up ppcg rep to get attention on a codereview question haha

^

^^

it seems easy to abuse that though

@ןnɟuɐɯɹɐןoɯ I think I'll try porting your answer to Jolf.

X3

so i understand why you can't

10:18 PM

@quartata I really should.

Do it

I believe in you

Stuff just changes way too fast, though.

I get way too many new ideas.

WAY too many.

@undergroundmonorail transfers rep from one site to the next by carting rep through bounties

woah

Then pick a list of chars and stick with them

10:19 PM

I forgot I turned on my volume and a website yelled at me

@CᴏɴᴏʀO'Bʀɪᴇɴ Please do.

@NiKoLaPrO You are in the wrong place. One second.

@ןnɟuɐɯɹɐןoɯ :D

Although your answer looks quite similar already.

NiKoLaPrO

okay @quartata where i can ask?

I am new here

NiKoLaPrO

okay

I think this is the right place?

NiKoLaPrO

thanks for help :)

yes it is, ty

in my experience with non-ppcg stack exchange sites, it seems like the easiest way for a non-expert to earn rep is interesting, well-formed questions. it's so rare for there to be a question i know how to answer that doesn't already have a better answer than i could give and isn't a garbage question that no one's going to look at and upvote answers to

huhwhat?

Maltysen

10:21 PM

@quartata light the mod signal!

→ 3 messages moved to Android Enthusiasts

okay

If only having 1.5 bytes was possible...

Make a lang that uses half-bytes.

ballesta25

Just use 12 bit bytes

You could call them "swallows" or something.

Haha

10:30 PM

African or European?

@Doorknob冰 Ah man you beat me to it

NO

@ןnɟuɐɯɹɐןoɯ The solution in Jolf is longer than my own.

So just how many JavaScript golfing languages are there now?

I honestly think JavaScript is the most popular non-golfing language on here

Python is

at least last time I checked

10:36 PM

I suppose since you don't see any JS answers on old challenges

Nowadays though I see more JS answers than Python answers

Part of it is that ES6 is surprisingly golfy

The data dump still hasn't been updated since August 18, so I can't rerun my script to check ;(

@Doorknob冰 :/

Can't you make some kind of SEDE query for it?

no, SQL is too limited

Hm.

@quartata ES6 is my jam

ES6Jam

10:39 PM

Mmm

@GamrCorps I've seen that. I think GitHub oneboxed once upon a time but they've sinced changed their API and blocked requests like that so oneboxing is no longer possible. (IIRC anyway)

mınxomaτ

@AlexA. I doubt it used the GitHub API.

@CᴏɴᴏʀO'Bʀɪᴇɴ Owow.

@quartata Except for those function names.

@ןnɟuɐɯɹɐןoɯ yeah

Hence the JSGL's.

10:41 PM

@mınxomaτ Oh, okay. Well, regardless of how it accessed the oneboxing magic before, GitHub now blocks those kinds of requests. That's all I know.
