The Nineteenth Byte

I've never tried using it but it seems like a decent enough language. Though its creator has gone on record saying that if he had known about Scala he wouldn't have made Groovy.

quartata

Scala is trash though

Don't even

Alex A.

What makes it trash?

quartata

Functions are first class objects

Alex A.

12:05 AM

Why would that be a bad thing?

quartata

I wouldn't mind that

Except it's a JVM language

Alex A.

That's what makes it trash? :P

quartata

Other things

But that's one of my grudges

I don't like the syntax as much as Groovy either

Alex A.

That it's a JVM language?

Groovy is too

As is Java, Clojure (IIRC), and others

quartata

@AlexA. No that functions are first class objects AND it is a JVM language

Alex A.

I wouldn't mind that

El'endia Starman

@quartata Probably due to the languages I have used, I don't get why that's a bad thing.

quartata

It's forcing you to blend paradigms which I don't like too much

Alex A.

You seem to be contradicting yourself, or I'm not understanding

quartata

@AlexA. Part 1 of a 2 part message

I hit ENTER early

Alex A.

You don't like that functions are first class objects because it's a JVM language?

quartata

12:08 AM

Read: "I wouldn't mind that except it is also a JVM language"

Alex A.

Oh

quartata

I also just think (like NodeJS) it's overhyped really.

Anyways, functional + OOP = blergh

Alex A.

Gotcha

quartata

It has lazy evaluation too and yet they call it a web-friendly language (shoot me)

So yeah.

</rant>

Alex A.

What about lazy evaluation would make it unsuitable for the web?

quartata

12:11 AM

Suppose you need to send a packet at a specific time (say a heartbeat), do some other stuff, then check the response

Lazy evaluation means that the packet wouldn't be sent (at least by default) until the response was checked

If you're not careful....

You could time out or worse

Alex A.

Hm. Okay.

Thanks for the explanation. :)

quartata

np

El'endia Starman

Agreed.

Basically, lazy evaluation is bad when you need precise timing?

quartata

Yes.

Which is often something you need in web-based applications and stuff

Oh crap I just realized something.

I need to use Python.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

:O

El'endia Starman

:D

quartata

brb porting code to a language I haven't used in 2 years

El'endia Starman

12:18 AM

Why do you need to use Python?

quartata

AST literal eval

TanMath

@El'endiaStarman um... because python is amazing!

El'endia Starman

ahh

quartata

If I use Groovy Eval.me( will mean I can't put it on TIO

Security risk

El'endia Starman

@TanMath I agree, but that doesn't force a need.

Maltysen

12:20 AM

@TanMath true dat

quartata

How should I turn a string into binary? I.e H => 01001000

Maltysen

@quartata map bin

quartata

Oh nice

Maltysen

@quartata well first ord

quartata

Ah OK

Maltysen

12:25 AM

"".join(bin(ord(i))[2:] for i in "hello")

quartata

Somewhat amusingly, Perl doesn't have bin. You have to do map { oct "0b".ord($_) } split(//,$string)

Maltysen

but wait that won't be padded

quartata

I didn't know if Python had it or not

@Maltysen Won't matter

I actually want it to not be padded.

Oh wait...

Hm.

I guess I can use sprintf to pad it to 4 bits

That's a thing, right?

Maltysen

nah, zfill

quartata

?

Maltysen

12:27 AM

btw, I found the full thing:

quartata

Oh, OK.

Maltysen

Japanese Banana Commercial

►

its not any better in context

El'endia Starman

@AlexA., look.

quartata

Awh what you have to use a lambda with map

lammmeeeee

OK just to check. Am I python-ing right?

code = map(lambda z: zfill(bin(ord(z)),4),open(sys.argv[1],'r').read().split(""));

El'endia Starman

That looks about right.

quartata

12:33 AM

Good. I think I'm starting to remember how this weird language works.

El'endia Starman

> weird

quartata

deal

Maltysen

@quartata use a list comp

El'endia Starman

ಠ_ಠ

quartata

@Maltysen ?

Oh, you mean that for thing?

El'endia Starman

12:34 AM

The time it takes for me to type the disapproval face goes way up when ಠ_ಠ hasn't been around in a while.

Maltysen

yeah

quartata

I find map more readable.

Looks the closest to Perl.

Maltysen

[bin(ord(i))[2:] for i in "hello"]

quartata

This isn't for golf or anything so

Maltysen

yeah but its so much more readable

TanMath

12:35 AM

thank goodness @RikerW is not here...

Maltysen

also, you need the [2:]

quartata

@Maltysen Why?

Maltysen

cuz pyth prepends 0b in bin

quartata

Oh, that's dumb.

OK.

El'endia Starman

@quartata Do be aware that code will be a map object, not a list. It will work exactly like a list if you use it like an iterator, but not any other way.

Maltysen

12:36 AM

so you should use a generator comp

quartata

@El'endiaStarman Aware. Using it as an iterator so I should be OK

Maltysen

and put it in "".join

or do you not want that?

El'endia Starman

@AlexA. - this too.

quartata

Oh I forgot to strip the trailing 0s

Maltysen

oh one more thing, don't read like that

use with

quartata

12:37 AM

Oh, auto-close?

Mkay.

This isn't right anyways, I forgot.

I need to bitshift by 4 first

Actually, hmm.

Oh, this is OK.

Maltysen

does anyone remember that latex gif service?

@Maltysen codecogs

^

cool thanks

Need to split it into 4 bits after though

TanMath

12:38 AM

@quartata you ninja'd me...

quartata

Split a string into chunks of x?

Maltysen

there's a really nice iter solution

Q: Cookie Balancing Act

Cookies are being served! Sibling rivalry ensues! Each of the twins wants the maximum quantity of cookie. The problem is that the cookies are of somewhat different sizes, not surprising since they are home baked. SO you weigh each of the cookies and devise a program to help you allocate them to e...

popularity-contest

TanMath

^ now this is why I am happy @RikerW is not here...

Maltysen

zip([iter(x)]*n)

but that splits it into n chunks

TanMath

12:44 AM

@NewMainPosts I will use you to my advantage! muahaha!

quartata

Well, that's fine....

Maltysen

so, zip([iter(x)]*len(x)/n)

quartata

I just meant x as a general number

So, zip([iter(string)]*4)

thanks

Maltysen

no that's 4 chunks

not chunks of 4

quartata

Oh.

So len(string)/4?

Maltysen

12:46 AM

yeah

quartata

Mkay.

Maltysen

but isn't it always 8

quartata

Don't worry about the logistics of what I'm doing :P

Maltysen

lel

quartata

I know it sounds insane

But I know what I'm doing trust me

Maltysen

12:47 AM

you did join the string, right?

quartata

@Maltysen Ye.

Maltysen

k, just making sure

quartata

(not to brag but in Perl this is @x = $string =~ m/..../g)

:P

trichoplax

Why the 1kg limit on cookies?

TanMath

@trichoplax that question is badly designed...

trichoplax

12:48 AM

It doesn't look ready yet

TanMath

@trichoplax probably never put in the Sandbox...

trichoplax

One vote from being put on hold

Maltysen

It sounds like homework

trichoplax

You can tell it didn't go through the sandbox from the typos

quartata

That and the guy is a new user.

I didn't even sandbox my first challenge....

I did have the (slight) common sense of asking about it in chat though.

We need to figure out a way to make people more aware of the Sandbox I think.

TanMath

12:51 AM

^

quartata

Hmm, I'm not sure if I like the current way I have this set up. On the one hand, it means that everything is in binary strings which makes coding less of a pain in the ass, but on the other hand I think it would be faster to just use bitwise operators and leave it as an int.

TanMath

I told him now to put it in the sandbox:

Welcome to PPCG! Currently, as this question stands, the specifications are unclear and the question is badly designed. I recommend that you should delete this question, then post it in the Sandbox, where we can give you feecback on how to improve your challenge. Then this question can be reposted as a much better challenge. — TanMath 1 min ago

quartata

I'll leave it as is for now.

TanMath

@Maltysen I disagree...

Maltysen

@TanMath the part about the first line being the number of input, and the next being the inputs

quartata

12:53 AM

fuck he deleted the question right before I was going to leave him a comment that was actually important

sigh

Well, he's never coming back.

Alex A.

@El'endiaStarman AHHHHHHHH it's so cute

El'endia Starman

@quartata New users not looking at rules/whatever is a common problem across all SE sites.

Alex A.

@quartata ?

quartata

@AlexA. Just a new user.

@AlexA. d'awhhhhhh

I totally missed that

TanMath

@quartata so my comment was bad?

Alex A.

12:54 AM

@El'endiaStarman <3<3<#

quartata

Oh doge is so cute <3

@TanMath no it was great

But I had something additional to say

TanMath

I hope he does as I said...

El'endia Starman

@AlexA. ^_^

TanMath

It has the potential of being a good challenge...

quartata

> Welcome to PPCG. This should have been a code-golf, not a popularity-contest. popularity-contest should only be used in challenges where humans can score answers better than an quantitative scoring system.

TanMath

12:55 AM

true...

trichoplax

@quartata It's hard to do more than the featured meta post we already have - new users who don't start with chat just won't know. The only thing I can think of is prefixing every question on main with "thanks to the users in the [sandbox] for all their help getting this question ready" but that might be overkill ;)

El'endia Starman

Okay, JavaScript question. Let's say I have a string "rule17text". How can I extract the number in the middle? I'd prefer to avoid using substr because "text" may also be "dead" or "alive".

TanMath

you can say that when he posts a Sandboxed version...

El'endia Starman

@trichoplax And cluttersome.

TanMath

@trichoplax we should put it somewhere in the tour...

El'endia Starman

12:56 AM

New users often don't read the tour.

trichoplax

@TanMath I don't think people who read the tour are the problem...

Alex A.

@El'endiaStarman The tour isn't really helpful on this site.

TanMath

@El'endiaStarman really? i guess...

El'endia Starman

@TanMath The thing you have to keep in mind is that everyone is acquainted with forum software and how those work.

SE is not a forum. Hence the problem when users think it is.

TanMath

I never even knew this website existed:

quartata

12:57 AM

@El'endiaStarman Regex. /.*?([0-9]+).*?/. Then get your number with $2 or whatever the equivalent is in JS.

trichoplax

I'm encouraged by reading the comments on this question where a brand new user responded very positively to feedback resulting in a much improved question.

TanMath

I agree...

El'endia Starman

@quartata "whatever the equivalent" is my problem. :P

trichoplax

@TanMath That started out as "moderators.se"
