Does anyone here know Perl?

Pavel

s/know/use No one truly konws Perl.

ASCII-only

@WheatWizard a bit

Riley

@WheatWizard I know some perl

Probably not enough to help though.

ASCII-only

only people like tails from anagol truly know perl

DJMcMayhem

@Pavel except for ton hospel

Wheat Wizard

00:03

What does the program @! do?

ASCII-only

also teebee, ton and mitchs

Pavel

> The only way to determine wether or not a string is valid Perl is to run it.

Wheat Wizard

It is valid perl (I have run it)

ASCII-only

pretty sure it's just a weirdly named array variable?

Wheat Wizard

ok

good

Riley

00:06

@ASCII-only That's what I thought. Notepad++ doesn't highlight it, but that doesn't mean much.

ASCII-only

pretty sure it isn't initialized

but yeah anything starting with @ is an array, anything starting with $ is a scalar (not an array)

Riley

Yep, looks like it's just an array tio.run/nexus/perl#@@@gqGCroJGok6STrGnNVVCUmVei4KD4/z8A

Wheat Wizard

So it is essentially a noop on its own?

Riley

Yep

@Downgoat right now we're trying not to add any more names for people who already have at least 1

How does one go about changing one's username on the chat profile?

ASCII-only

@1000000000 change username on one account -> change parent user

Riker

@1000000000 go to your chat profile and change your parent account

your chat profile username is the username of the parent acconut

i.e. PPCG, SO, arqade, etc

0 '

@ASCII-only @Riker Thanks

Conor O'Brien

@0' nice username

ASCII-only

00:12

@0' 0/10 the derivative of 0 is just 0

Riker

I can't imagine I'll remember that name.

Too long.

Conor O'Brien

CMC: given an integer n, generate a triangle of n. For n = 5, the output might look like this:

ASCII-only

does there need to be a space

0 '

@ConorO'Brien I believe it is the username with the lowest lexicographical ordering possible on SE

Conor O'Brien

00:14

@ASCII-only yes. but it can also be a 2d list/array, optionally 0 padded to the right

Wheat Wizard

@ConorO'Brien Can it be a 1D array with zeros padding?

Conor O'Brien

@WheatWizard sure

ATaco

RProgN2, 8 Bytes. R{1\Rp};

Input in the header because IO is currently improperly implemented.

Riley

@ConorO'Brien <s>05AB1E, 4 bytes </s> Doesn't output the last row

ATaco

That doesn't output the last row.

Conor O'Brien

00:16

^

ASCII-only

@ConorO'Brien what about n=10

Riker

rip python's range function

Conor O'Brien

something like

1

1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7

why? lol

Conor O'Brien

@ATaco also that's in reverse >_>

ATaco

oh

Well that's a bug with my Range function.

Good to know that exists.

Conor O'Brien

Stacked, 4 bytes

Riker

rekt

ATaco

00:21

Oh, I forgot to actually implement \ .

That could cause it.

Wheat Wizard

@ConorO'Brien Brain-Flak 84 bytes

ASCII-only

;_; i'll have to make it noncompeting

ATaco

As do I...

But I can do it in 4 bytes theoretically.

#S\S

ASCII-only

i can do it in 15 bytes theoretically

ATaco

I actually like that solution, very simple.

#S is the "Stackify" function, \ puts that function under the input, and S then stackifies. So the input is converted to a stack with each value being converted to a stack.

ASCII-only

about calesyta: here is the esolangs wiki page, i think anyone with a wiki page for their submission should add it there

PhiNotPi

I wrote a program to generate tie knots, given some parameters.

I'm able to specify the desired basic look / size of the knot, and it will generate a list of options.

example output:

{[L, R, L, C, R, C, L, C, R, L, C, U] w:11 sy:-1 sh:2 tw:0 (-1 2 -2, 1 2 2 | -1 -1 1)->(eld) cm:8}

represents the following knot:

Pavel

@PhiNotPi Now go make it a challenge.

Riker

@PhiNotPi define "basic look"? how do you feed in that input

PhiNotPi

@Riker There's four main categories of knots depending on how the topmost layers are arranged. But I can also specify the desired "complexity" of the face of the knot, measured by the number of pieces of fabric which are visible.

Riker

oh cool

PhiNotPi

There are also several other mathematical properties that are filtered for, such as left-right symmetry (so both halves of the knot are equal size) as well as getting the width-height ratio in an acceptable range.

Riker

01:10

oh nice

PhiNotPi

The numbers in the output give a pretty good prediction of what the knot will look like.

Pavel

No we do not.

ais523

60% of the list! admittedly, it required some favorable randomness, but even so, one image can say a lot

Pavel

Take that CodeReview!

ais523

and this is despite me not even trying to hit HNQ over the last couple of days; I've just been sitting back and enjoying the ride, getting more and more scared as it goes

Pavel

02:48

Wait, are those all yours?

ais523

no, only one is

I have three challenges there at the moment though

Pavel

Still pretty good!

ais523

yes, this is a community effort

someone joined the site to upvote one of my answers, I think that's worthy enough

Pavel

Wait, do you use Goat's userscript? Shouldn't the icons be the fancy ones, and not the design-less ones?

ais523

although my proudest achievement of the last 24 minutes is the 5-char Turing-complete subset of JavaScript; that was a community effort too

but it's been widely competed

Pavel

02:50

Oh yeah, I was there.

ais523

and I don't use any userscripts, it's just that none of the sites on that HNQ minilist have designs

Pavel

D: Why don't you use the Design Script?

ais523

I do all my PPCGing in incognito mode, I don't run it in my primary browser

installing a userscript every time would take far too long

Pavel

Wait, why do you need incognito for PPCG?

ais523

@Pavel it creates accounts for you (and thus tracks you) even when you're logged out, I find that fairly disturbing

Matthew Roh

Pavel

If you're in chrome, you can just enable extensions in incognito in the settings.

Pavel

Matthew Roh

ok then

but "foked from" is a bit awkward

Pavel

@Downgoat Seems good, I think you should make a tab for the repo's wiki.

@MatthewRoh That is also the proper terminology.

Downgoat

02:56

@Pavel wiki or README?

Matthew Roh

huh? why?

isnt "forked from" correct?

Pavel

Oh, I misread

Downgoat

@MatthewRoh I think he's reffering to the "Also you could change 'code' to 'repos'"

Pavel

Like three times

Downgoat

does the name/fork seem clickable when you see it?

Matthew Roh

02:57

I mean, people seeing the word 'fok' in goathub is a bit awkward

no android app ;_;

Pavel

@Downgoat The wiki, I don't feel that the README deserves it's own tab, you can just do the same as GitHub where it's shown below all the files (Maybe scroll it independently from the rest of the screen, in it's own box).

@Downgoat Very.

Downgoat

@Pavel yeah, that's what I was thinking.

Wiki might come later, that'll require some page stripping

Pavel

Search bar.

It needs a search bar.

Downgoat

I'm trying to create a minimal version that I can start distributing for beta testing

@Pavel I have one of those for personal repos. Search API limitations are tight though. Only like 20 req/hr IIRC

Christopher Peart

Downgoat why do you have something called "PPCG design" that thing will never happen

Pavel

03:01

No Windows Phone version?

(Cries)

Christopher Peart

@Downgoat droid?

Pavel

@ChristopherPeart It's a userscript

Christopher Peart

@Pavel it was a joke

:P

Downgoat

@ChristopherPeart what do you mean by "droid?"?

Christopher Peart

@Downgoat android

Downgoat

03:01

what about android?

Christopher Peart

@Pavel my dad went to the google Pixel for the appstore

@Downgoat will you support it

@DJMcMayhem can I have hex as my username?

Conor O'Brien

@MartinEnder Kind of a retina feature request: that $* work with capture groups as operands, e.g. $1$*$2 or something

Downgoat

I am considering it but iOS is priority, so will do that first

@ConorO'Brien more golfy: $1*2

Pavel

I came up with a solution where you can make it for Windows Phone and not waste your time completely. You can make it a Windows Store app, and make it compatible for both.

Downgoat

@Pavel hahahahaha windows phone

nice one

:P

Pavel

03:03

;-;

Christopher Peart

@Downgoat Windows phones are nice!

Conor O'Brien

@Downgoat but then that would mean 2 repeated $1 times

Christopher Peart

Like legit

They are actually super nice

Downgoat

@ConorO'Brien oh crap whoops

Pavel

Amazing phones, zero app support.

Downgoat

03:04

I will earn $0 for making windows phone app

no one will buy :(

Conor O'Brien

Pavel

Microsoft gives you money every time someone downloads your app

Even if it's free

Downgoat

wait what

brb targeting windows phone

Pavel

Discalimer: May or may not be 1/1000th of a cent per download

Downgoat

As long as I can develop for both android & windows phone at once I am OK with distributing

Christopher Peart

03:06

@ConorO'Brien what sucks is the phones are very very nice

Downgoat

@Pavel They are 100 goats on my farm so that is 0.1 cents :D

Pavel

Well, I'd download it.

Christopher Peart

@Downgoat how much will the app cost?

Downgoat

@ChristopherPeart So is my wish to buy a pygmy goat but it's not going to happen either

@ChristopherPeart None but push notifications require a server, for this I am offering two cases: 1) use my server for some cheap price of like $.99 2) server will be open source so you can download from github and deploy yourself

Christopher Peart

@Downgoat cool

If you do android I would try it

Pavel

03:11

Actually, strictly speaking you don't get paid every time someone downloads, but every time someone views an ad on it.

Which is almost the same thing, there really are no free windows phone apps without ads and a 99 cent microtransaction to turn them off.

Downgoat

I would like to add ads to my app but that would be very annoying

Pavel

If they only exist on the WP version, if the alternative is the WP version not existing, I will bloody well pay those 99 cents to turn them off.

@Downgoat what language are you writing DownGit in?

Downgoat

Swift

Is everyone going to use their own name for GitGoat... :P

Pavel

iirc Android want you to use Java, and WP requires .net

Downgoat

oh god .net

Pavel

03:17

J#?

Christopher Peart

@Downgoat GitGoat is the official name? Yasss

@DJMcMayhem @Riker In The Peoples Python can you please swap me with wheat for __import__?

Destructible Watermelon

dammit, this going to need a lot of rewriting I think. I need to rewrite how the player interacts with the controller

and then a fair amount of code depends on how it is currently written

can I just ask the players not to modify their own health?

Thomas Ward

@wat fun fact, @Riker needs to do a bit of code revisions for "The People's Python" :P

Destructible Watermelon

Guys, for a koth can I rely on the bot classes not modifying one of their stats?

as in healing itself

Thomas Ward

@wat ... mostly because he's made what I think might be some egregious errors with exception handling heh

@ThomasWard aaaaahhhh, code reviewer! :P

@DestructibleWatermelon You can declare it as a private variable in the superclass.

Destructible Watermelon

@Pavel uh wat

Pavel

This isn't a java question is it

Destructible Watermelon

03:50

doesn't private mean only the bot itself can access it

Thomas Ward

@Downgoat not my fault @Riker got up and dropped it into CR :P

Destructible Watermelon

and so is the exact opposite of what I want?

Pavel

You can add public getHealth() { return health; }

Destructible Watermelon

umm

why would all my bots share the same amount of health

Pavel

It's not static

Destructible Watermelon

03:52

also is python

@Downgoat though this is not ultimately what drew me to this room, of course, it's an interesting coincidence i'm the only reply to @Riker's inquiry. :P

In that case, it's enough to specify that bots may not modify their own HP directly.

@Dennis leftgoat should be reversed

@Pavel you have awesome CS class

we here make BankAccountTester

Destructible Watermelon

@Downgoat Wouldn't that be upgoat?

@Downgoat BTW, do you mind if I steal some of your source code? I have no idea how to write a proper parser >_>

Destructible Watermelon

Imagine a 2d language actually used for professional code because it is actually useful...

Dennis

O.O

Destructible Watermelon

what exactly is an algorithms class?

PhiNotPi

solution: make a 2D language (any quality is acceptable), but then give it the best scientific computing library ever.

Wheat Wizard

04:21

@DestructibleWatermelon Its a University course required for computer science majors that teaches people how to write code that doesn't have a ridiculous order notation.

Pavel

@PhiNotPi So, transpiles to/from Mathematica?

Destructible Watermelon

you know, a lot of my more recent code has had terrible order notation. Specifically Turtlèd code

the square number generator is ridiculous I think

or maybe my interpreter is just crap

Thomas Ward

your interp. is failing, that's always the reason.

Destructible Watermelon

I think it'd still take a while anyway

yeah, its definitely pretty bad with how it uses strings when it could use numbers, but still

my code is pretty hard to read. the spaces are each made up of a list, with two lists in it and a bool, which says whether there is a flag. the lists have the amount of each team in it and if any on a team is holding the flag

this is why I must work on this alone

and also for the sake of your own sanity you may not look at the source code anymore

Pavel

Submit it to CR

Thomas Ward

04:29

and prepare for a reaming :P

Destructible Watermelon

no, even though the people on CR suck

I do not hate them that much

Downgoat

@Pavel steal source code from where?

It is OK if you link to author and source

Pavel

The GitHub repo, but it was mostly a joke.

I'm using Java, not Node, so it won't be too helpful.

Destructible Watermelon

example of a function from the code

def has_enemy(space, team):
    if not is_wall(space):
        index = 0 if (team == 1) else 1
        return space[index][0] > 0

Pavel

I've been looking through though, just seeing how everything is put together.

Destructible Watermelon

04:38

I have an awful feeling my koth is always going to be way too slow

and that I won't be able to speed it up

Pavel

Destructible Watermelon

but code review

also their heads might asplode

Pavel

That's the point

This is a clever plot to drive them all insane as revenge for them getting a design before us.
