@nmjcman101 :D I'm glad to hear it!

I've learned a lot too, but that was mostly from learning/writing all the vimscript

Phoenix

@EriktheOutgolfer Your original and edited version seem to do the same thing.

DJMcMayhem

It's cool to see that other people are getting stuff out of it too

Business Cat

@Phoenix CJam, 11 bytes: 90{Amd<},9>

Erik the Outgolfer

@Phoenix original version is technically invalid even though valid in this case

DJMcMayhem

I think that answer is cool because it uses s two different times, but with completely different effects

Business Cat

17:01

Alternatively, A2m*{:<},9>

Phoenix

@EriktheOutgolfer What makes it invalid?

DJMcMayhem

I guess C would work too

Erik the Outgolfer

Ḍ means convert from base 10

Conor O'Brien

J repl, 42 bytes: ' '-.~,/>(2":]>:@+10&*+i.@(9&-))&.>;/>:i.8

Phoenix

And what does V do?

Erik the Outgolfer

17:02

had there been ints larger than 9 it would produce weird stuff

DJMcMayhem

@Phoenix Code golf.

Business Cat

V is eval, when you pass a list as argument it stringifies it first

Phoenix

._.

Erik the Outgolfer

@Phoenix yes

although the way you phrased it probably means what does the language V do, which is string manipulation code golf

Phoenix

I was asking about Jelly's V

TY Cat

DJMcMayhem

17:04

That's what I thought you meant at first. I was really confused at first, then I decided to mess with you

Erik the Outgolfer

what do Jelly, V, 05AB1E, SOGL, Pyth, Pyke and Charcoal do? code golf of course what else?

Phoenix

Too many golflangs

I think Leaky Nun manages to know all of them somehow.

Erik the Outgolfer

huh? he doesn't do 05AB1E, SOGL, Pyke and Charcoal afaict

he mainly does Jelly

totallyhuman

@Phoenix are you jelly

Phoenix

No

totallyhuman

17:08

oh

well ok

Phoenix

I am Java, Mathematica, and occasionally Ruby.

totallyhuman

mathematica?!

Erik the Outgolfer

mathics

because who has money for mathematica?

Phoenix

I didn't pay for Mathematica. They give it out for free a lot.

Especially to students.

Erik the Outgolfer

I'm not in university yet :(

Phoenix

17:10

Neither am I

Erik the Outgolfer

so...how are you considered a student?

Phoenix

I'm in 10th grade, a student of Tesla Stem High School.

totallyhuman

o.o

you get stuff as high schooler?

Phoenix

Yes.

totallyhuman

looks for all the student stuff he can

Phoenix

17:12

I got the Jetbrains complete pack thingamajig

totallyhuman

what

that's ridiculous

for how long?

Phoenix

As long as my school email remains active, +1 year.

Erik the Outgolfer

tesla stem has money to pay???

because someone's got to pay for sure

Phoenix

No, They just give it to free for people with a school email address.

totallyhuman

somebody put the welcome comment on this

Phoenix

17:13

jetbrains.com/student/?fromMenu

@EriktheOutgolfer We do have better funding than many schools, fortunately. We were able to afford three 3D printers and a laser cutter.

Erik the Outgolfer

O_O

Riley

@totallyhuman Done

Erik the Outgolfer

is there a specific welcome comment or you just type similar stuff?

who downvoted that? the new user should feel welcome even though an off-topic question is their first interaction

Phoenix

:-; I didn't snipe the CV because I thought I was on SO.

Riley

@EriktheOutgolfer codegolf.meta.stackexchange.com/q/11807/57100 near the bottom.

totallyhuman

17:18

jetbrains doesn't have my school registered ;-;

Erik the Outgolfer

somebody make a userscript out of that

Phoenix

RIP

@EriktheOutgolfer Someone did, search StackApps

Erik the Outgolfer

@Phoenix what?

Phoenix

A userscript that allows you to paste in commonly used comments.

Erik the Outgolfer

ppcg-specific?

oh you mean add that comment manually

I think I have that userscript

even though a bit outdated

@MDXF Ah, gotta wait till I get home to make any more progress on it. My employer is pretty cool, but I doubt they'd appreciate Minecraft on my office workstation.

@Downgoat Typo on your blog post

But regular expressions is not as much greek letters; therefore, you may of grown used to seeing regexes such as:

Q: Decrypt xor-encryption

Your task is to take an encrypted string as input, and output the string decrypted, to reveal it's hidden message. The strings, both the input and output, will contain characters from this list of 64 ASCII-characters (note the leading space). !"#$%&'()*+,-./0123456789:;=?@[\]_abcdefghijklmnopq...

Kritixi Lithos

windows what?

Riley

@Adnan In 05AB1E what counts as truthy? Just 1 or anything not 0? If statements (i) check if TOS is equal to 1, so 2 goes into the else, but 2__ is 1 not 0.

Okx

@Riley 'Truthy' is defined by the if statement

See this

Riley

So 1 is the only truthy value?

Okx

17:52

I believe so.

Downgoat

@KritixiLithos like as an OS

Business Cat

05AB1E is weird

Riley

Is there a 1 byte way to convert a number to 1/0? The shortest I can think of is __.

Okx

É?

haven't tested

Downgoat

KuanHulio

17:54

i thought anything could be a truthy or falsey value

Riley

@Okx That just checks if it is odd.

Adnan

@Riley Yes, only 1 is truthy, the rest is falsey

Question: anyone familiar with iOS app dev want to halp make PPCG app? (@Mendeleev I know you have made apps before)

Speaking of the app, is there an SVG of the PPCG logo I can use

Mendeleev

@Downgoat I made a counter app. It had two buttons and a number display.

Conor O'Brien

@Downgoat I'm sure I could pick it up quickly enough

Kritixi Lithos

18:05

@Downgoat you posted that on TNB just as soon as Evil Sheep posted a comment on that meta question

Conor O'Brien

the language is swift right?

Kritixi Lithos

the only experience with iOS dev that I have is that XCode is a big piece of poop and it sucks and iOS sucks and Obj-C and Swift are weird

Mendeleev

I can try to make android app

Poke

as i recall xcode isn't too bad but i agree that objective c is weird

Mendeleev

I think SE chat was just down

Adnan

18:08

@Riley Just to be sure, do you mean mapping 2 -> 1 or 2 -> 0?

Kritixi Lithos

@Mendeleev I think VTC is making the android app

Mendeleev

oic

Kritixi Lithos

yesterday, by VoteToClose

@KritixiLithos I hate Swift, so, Android.

so yeah, people care more about Android than iOS

Downgoat

;_;

Conor O'Brien

that's, uh, a little rash to say

MD XF

18:14

But accurate...

DJMcMayhem

@ConorO'Brien Not really

Riley

@Adnan 2 -> 1. The same behavior as __ (negative bool X2)

Wheat Wizard

What is the difference between a lambda and a function in python?

Riley

@Adnan Thanks!

Adnan

@WheatWizard I think a lambda is anonymous

Wheat Wizard

Yeah, but does it act different in any situations? (other than print x)

Adnan

As far as I know, it also doesn't allow assigning values to variables

but I'm not sure

Wheat Wizard

18:23

I'm having a very strange issues where lambdas are behaving entirely differently from functions and I can't seem to track down the source

Phoenix

Paste code?

Nathan Merrill

@WheatWizard language?

Wheat Wizard

Python

@Phoenix Its a pretty large program across two different files

If you want to see it I can show you but its not going to be pretty

Nathan Merrill

so one file is a bunch of lambdas, the other is a bunch of functions?

Wheat Wizard

No, I have a list of mixed lambdas and functions, some of them are being called

all of the lambdas return the same thing no matter how I define them

I'll try to recreate on a smaller scale

Try it online!

Maybe its just lambda weirdness, but I feel like that shouldn't be happening

Nathan Merrill

18:31

its because python doesn't create closures

you are reassigning the char variable repeatedly

Wheat Wizard

hm

Nathan Merrill

and when the lambda comes around, it accesses the char variable at instance it is at

Wheat Wizard

Is there anyway around that?

DJMcMayhem

Functions don't work either Try it online!

Q: What do (lambda) function closures capture?

Recently I started playing around with Python and I came around something peculiar in the way closures work. Consider the following code: adders=[0,1,2,3] for i in [0,1,2,3]: adders[i]=lambda a: i+a print adders[1](3) It builds a simple array of functions that take a single input and retu...

python lambda closures

Nathan Merrill

18:34

ew, some of them are using default parameters

lambda char=char:char

I mean, that works, but I'd seriously reconsider refactoring, and simply putting the data in an array instead of functions in an array

Wheat Wizard

(lambda b:lambda:b)(char) looks even worse

The functools solution looks the nicest

@NathanMerrill I don't know if I can refactor, most of my functions take args, and different functions take different numbers of args

I should probably go to CodeReview some time.

Nathan Merrill

sounds like a great use case for tuples

they can easily unpack into any number of arguments

Wheat Wizard

I'm not sure I follow, how would a tuple replace a function?

Nathan Merrill

like, if you store the arguments to a function instead of the function itself

Wheat Wizard

Then where would the function go?

Nathan Merrill

18:44

args = [(1), (1,2,3), (2)]
for arg in args:
     f(*arg)

as opposed to

funcs = [lambda: f(1), lambda: f(1,2,3), lambda: f(2)]
for func in funcs:
    func()

Wheat Wizard

Oh I have a bunch of different types of functions that do different things in the array. Is here any way I might apply this?

Nathan Merrill

you have different functions that do different things with different arguments, but all return the same kind of thing?

I mean "kind of thing"

like, they all return an integer representing how long it took or something?

Wheat Wizard

They return different kinds of things as well

I'm building a function tree

Nathan Merrill

so, you're parsing a(b(c(2),3),1,3)?

Wheat Wizard

Yeah

In a way

It doesn't much look like that but thats essentially whats happening

Nathan Merrill

18:49

you'll actually want to wrap every parameter in some sort of "Resolver"

couple of questions: is there scoping?

Wheat Wizard

In python?

Nathan Merrill

no, in your language

Wheat Wizard

There is no scoping

there are no variables

Its not really a language, Its part of a larger project

Nathan Merrill

ok :)

well, I'm going to assume this is python, just so I have something to go off of

Wheat Wizard

It is in python

Nathan Merrill

18:51

basically, you have a list of tuples:

@WheatWizard that I'm parsing pythong

Wheat Wizard

Oh ok

Nathan Merrill

each tuple would contain two items: a function reference, and a list of parameters

each parameter would basically be a zero-argument function that I can call to get the parameter value

does that work for you?

(the zero-argument function is what I was terming the "resolver")

Wheat Wizard

I'm not sure what the parameters are?

Nathan Merrill

that's why you use a lambda: it'll resolve to whatever it ends up being at runtime

like, if you had a bunch of variables, you could put them in a map where the key is the variable name, and your lambda would call the map asking for the value of a particular variable name

(I know you don't have variables)

Wheat Wizard

Ok

I think I see

Nathan Merrill

18:57

that said, I'm working on a limited amount of information

15 mins ago, by Wheat Wizard

I should probably go to CodeReview some time.

that sounds like a good idea :)

Wheat Wizard

Ok thanks for everything

Sorry that sounded sarcastic

I am actually thankful.

TuxCopter

damn that's evil

Wheat Wizard

@NathanMerrill Here's the question if you are interested

Kritixi Lithos

@TuxCopter what's evil? Asus?

MD XF

No, putting the power key right by the backspace

TuxCopter

^

MD XF

I mean, you may feel otherwise, but I personally don't like rebooting every time I make a mistake in my code

Kritixi Lithos

19:27

that's the same for my badly-built laptop

but the good thing is that it doesn't power off if you press it for just a moment

Business Cat

Making the power button a key on the keyboard period is evil

Wheat Wizard

Does it not warn you when you hit the power button?

MD XF

Wait... I thought New Main Posts was a bot.

This speaks other words...

MD XF

19:31

Oh, so mods can edit messages

Kritixi Lithos

@WheatWizard it doesn't warn me

MD XF

Oh that's right. I remember now

Helka Homba

@Linux/Mac Users: is it natively possible to output audio through two sources, like two pairs of headphones (without a physical cord splitter)?

Wheat Wizard

It is on Mac

Helka Homba

As far as I can tell it is not in Windows

Wheat Wizard

19:35

Its much harder on Linux

I've done both Mac and Linux before, I've never tried Windows

Helka Homba

Was wondering why something so seemingly basic (akin to plugging in 2 usb drives) is not easily supported :/

Q: Are there any functional programming languages designed for code-golfing?

Are there any functional programming languages designed for code golfing? I know that golfscript and CJam fulfill the same category for stack based, but I couldn't find a functional code golfing language.

tips functional-programming golfing-language

totallyhuman

@NewMainPosts /disapprove why

Wheat Wizard

@HelkaHomba Do you want to output the same thing from two sources or two things from different sources?

totallyhuman

Why would you want a golfy Haskell

Wheat Wizard

19:38

Because Haskell is fun, and golfing is fun

totallyhuman

Aussi what's unclear about that?

Helka Homba

@WheatWizard the same thing (but the option to output any to any would be nice, hint hint @MS)

totallyhuman

...I am not going to correct that because it is already correct

MD XF

@NewMainPosts Awful >.<

Wheat Wizard

Thats rather easy using aggregate audio output on Mac. But that probably doesn't help you.

Helka Homba

19:41

Well, that just tipped the mac scales one more notch in their favor

totallyhuman

D:

Helka Homba

But I'm steadfast with my dislike of miniature, round exit buttons

And no right click >_>

totallyhuman

i think they have that two finger click thing, right?

Helka Homba

and phones with one front button and ever fewer ports >__>

Wheat Wizard

@HelkaHomba Thats a hardware thing, OSX supports right clicking

You can also use control click if your hardware doesn't support the right click

totallyhuman

19:50

uh

what

Helka Homba

@WheatWizard Yeah. Just my old schools always had one-button macs and I hated having to use them

totallyhuman

a keystroke in place of a mouse click?

also control key vs. command key

Wheat Wizard

@totallyhuman I actually don't have a functioning click at all

I use keystrokes for most things, I can move the cursor though

Helka Homba

@WheatWizard In windows you can control click to select multiple files, and shift click for a ranges of files. I wouldn't want to lose either of those

Wheat Wizard

Its shift click for range and Command click for individuals on Mac

totallyhuman

19:56

alright time to golf my brain
