Q: Display a Lemnescate (∞)

The infinity symbol is also called a lemnescate. Your program must draw a lemnescate with text via standard out (formatted with newline feeds) or graphically. The infinity symbol (by my standards) must be continuous (that is, every non-whitespace character must be touching two other non-whitespa...

JK, I have no idea

Phoenix

Also possible unclear but that's more subjective.

@HelkaHomba reddit.com/r/askscience/comments/3rchs6/…

According to some internet people in ^ there isn't one.

Conor O'Brien

@Phoenix you're kidding, right? that's a little harsh. You could, idk, tell the user, like totallyhuman

Phoenix

I also think it's a bad and poorly specified challenge.

Conor O'Brien

@Phoenix It's bad, but not poorly specified, except for maybe the last sentence

Really.

That's a lemniscate.

Just to be clear, I voted to close

Conor O'Brien

> The infinity symbol (by my standards) must be continuous (that is, every non-whitespace character must be touching two other non-whitespace characters diagonally or orthogonally). It must also have two and no more than two gaps of enclosed whitespace (connectivity for whitespace is only orthogonal). Thus, the following output fails:

But I will retract on improvement

FWIW I like the idea of a challenge with multiple accepted outputs, since it gives more freedom and variety in answers; this particular challenge doesn't capitalize on this variety, since it will almost always be optimal to print he little hexascate

@Doorknob Er, uh, wait, apparently that's not true. I tried in private browsing and I couldn't see mine.

I'm sure that used to be the case, though.

Conor O'Brien

why should they hide that stat >.>

"oh no please don't look at me I'm addicted to this site"

Wheat Wizard

I could see why some people would want to keep that hidden

HyperNeutrino

everyone is, whether or not they'd like to admit it

Wheat Wizard

01:46

Though if they are hiding it they should keep the last seen hidden as well

HyperNeutrino

i liek how i've been a user for 2 months :3

Wheat Wizard

ideally you would have privacy settings where you could check these on and off.

HyperNeutrino

MSE post time?

@Doorknob so just mods right

Doorknob

Apparently.

HyperNeutrino

ooo

if they hide that they should also hide reputation because that way nobody can see how bad I am at PPCG :3

Wheat Wizard

01:48

Wait why would mods need to know that? If the information is private mods shouldn't be able to see it.

will have to go in a few though, summer school

@Doorknob ooh nice thanks

does it co operate well with the userscript?

Phoenix

@Doorknob You're KeyboardFire?? You made hotdog.vim???

ಠ_ಠ

Doorknob

@totallyhuman I will warn you though, there's a few recent CSS updates and I haven't updated it in a bit, so there are some blinding blocks of white currently. I have been in a state of planning to fix those but never having gotten around to it for some time. :P

totallyhuman

oh god i just looked it up

Doorknob

@totallyhuman Not sure which userscript you're referring to.

totallyhuman

01:54

what did you do?

Phoenix

@totallyhuman hotdog.vim, you mean?

totallyhuman

@Doorknob the ppcg design userscript

@Phoenix yup

Doorknob

@Phoenix Uh, I, er, did what now? I have, umm, no idea what you're talking about... >_>

Hotdog.vim is the most awful thing to ever exist.

@totallyhuman I have no idea.

i'm currently going through the process of purging hotdog.vim from my browser

what is hotdog.vim

Personally I prefer english quining. Qoute 'and then say it, after saying "Qoute".' and then say it, after saying 'Qoute'.

You also need to catch EOF

@DJMcMayhem Rip me

ATaco

Keep trying until you fail, then do this again. = function f(){try{while(true)statement;}catch(e){f()}}

The english is golfier than the JS.

I could spend all day doing theoretical English coding

"Should be said twice" should be said twice. Golfier quine.

Conor O'Brien

f=_=>{try{for(;;)s}catch(e){f()}}

Is there a way to check if a pattern is matched in haskell?

Aw, thats really long

Phoenix

@HyperNeutrino is.. is that... hotdog.vim.... in SE?????

HyperNeutrino

:3 yes

Phoenix

02:25

ლ(ಠ益ಠლ)

Challenger5

It is long. Depending on the type you might be able to do something else.

Wheat Wizard

I just want to check if a list is a singleton

Phoenix

@HyperNeutrino Does that affect the enire page or just the user card?

HyperNeutrino

Just my flair lol

Challenger5

@WheatWizard (==1).length?

Wheat Wizard

02:28

Yeah, thats how I'm doing it. It just feels really long

Challenger5

I don't know

Do you need the singleton value as well?

Wheat Wizard

No I don't

I have no idea then. I'm not very experienced with Haskell.

Wheat Wizard

No problem, thanks for the help

Challenger5

You're welcome

» typeof null
« "object"

Javascript why

TypeError: can't convert null to object

Javascript, why

Phoenix

null instanceof Object
false

Also, why is Object capitalized noramlly but lowercase when output by typeof

ATaco

Constructors/functions/libraries use CamelCase, but types use camelCase

Phoenix

!(typeof null == "object" ^ null instanceof Object) should be true for any language with typeof and instanceof.

ATaco

Apparently except JS.

HyperNeutrino

@ConorO'Brien Doesn't work very well, but here you go

HOW THE HELL DID YOU MAKE HOTDOG.VIM EVEN WORSE THAN IT ALREADY IS

HyperNeutrino

I'm missing some CSS parts so it looks worse than it will when I'm done :3 xD

@Doorknob You'd love to see this when I'm done

Phoenix

Hmmm.... I wonder what it looks like when both that and the gradscript are on....

What are line numbers

2

Mystery solved

Step Hen

Comments on this? Sandbox

Phoenix

I like all the freefloating red rectangles that don't line up with their corresponding elements.

Wheat Wizard

@Phoenix Those are relative line numbers.

(Perhaps you knew that)

Phoenix

02:56

I didn't

I don't like them

Why would anyone do that

Wheat Wizard

I turn line numbers off, but my roommate likes the relative line numbers.

Phoenix

I mean, I suppose it is hotdog.vim

Doorknob

What's the point in absolute line numbers? At least relatives numbers mean you don't have to count.

Wheat Wizard

line numbers are like syntax-highlighting, unnecessary frills that get in the way.

Phoenix

The only time I need any line numbers is when I'm looking at a stack trace and want to know where the error is.

Wheat Wizard

02:58

I just use a command to jump to the appropriate line

Doorknob

Shouldn't be using line numbers for that, just <num>G.

Phoenix

@Doorknob I didn't know that worked.

Wheat Wizard

I don't want to look at line numbers all the time when they are only useful 2% of the time.

Phoenix

Also, I'm not always using Vim

Doorknob

@WheatWizard I use relative numbers all the time when I want a motion to go to a certain place and there's no better one.

Phoenix

02:59

@WheatWizard Unnecessary? Maybe. Get in the way? Not really...

Wheat Wizard

I only use vim for latex, and nano for everything else. I really like vim, I just write very slowly.

Doorknob

@Phoenix Sounds like you need to fix that. :P

Phoenix

I use Visual Studio Code with the Vim plugin most of the time.

Doorknob

(joking, of course, although it's certainly something you can do)

Wheat Wizard

@Phoenix I like things to be very empty, I get claustrophopic when there is stuff everywhere on my screen

Phoenix

03:00

Have you ever used Java or C#?

They are actually quite difficult to use without an IDE, especially with larger projects.

Wheat Wizard

@Phoenix I wrote Java last summer as part of a legacy project at my lab. I do not like Java

I used nano for a while, but then switched to IntelliJ.

I don't actually like programming very much. I just like code-golf

Phoenix

Having auto-imports and auto-complete for foo.bar.baz.some.element.function() is a must for writing java

Wheat Wizard

I hated that in the IDE. it drove me insane

I don't like the constantly resizing window always following my cursor

ATaco

I like eclipse, personally.

Wheat Wizard

Or the IDE writing stuff for me. I just want the keys I press to appear on the screen.

Phoenix

03:03

@WheatWizard I assume that's because you didn't spend a lot of time writing Java code.

Doorknob

Having used vim for C, C++, Java, and (very briefly, fortunately) C#, I've never really felt like autocomplete would be particularly helpful.

ATaco

Me neither, but now I use it far too much.

Phoenix

When writing Java using a nonIDE editor, I sometimes found myself alt-tabing to the documentation multiple times in one line in some cases.

Wheat Wizard

I think that Java is probably best in an IDE, but that doesn't mean Java is good in an IDE

ATaco

Do you think /anyone/ would have put the effort that I did into RProgN's classes if it weren't for auto-imports..?

Phoenix

03:05

Should I be using size? length? length()?

@WheatWizard Well, yeah, C# improves on it in every conceivable way except portability.

And even the cross-platform support is good now.

Wheat Wizard

I wrote a bunch of C# like 5 years ago, I don't remember liking it, but I can't say my opinion from 5 years ago is very valuable

Phoenix

I suppose it depends on what you're used to.

I used to write a lot of Java, and C# for me is like the best thing ever.

I could see why someone more familiar with a language like Ruby wouldn't appreciate C#.

Wheat Wizard

I only know C++ and Python, so its probably just out of my comfort zone.

ATaco

@Phoenix Is it an array? Use .length. Is it a string? Use .length(). Is it a List? Use .size(). Otherwise, check the documentation.

Phoenix

@WheatWizard Oh, I thought you knew Ruby because RainFlak

Wheat Wizard

03:09

@Phoenix You would think. I just pretend its python and randomly insert ends until it runs

You should see the code, its a stinking pile of garbage.

Phoenix

I like the golfing aspect of Ruby and Python, but I absolutely can't stand dynamic typing for serious projects.

Wheat Wizard

I like dynamic typing, but I don't feel it blends well with OOP

Phoenix

Not at all.

The only places where dynamic typing seems useful, it can be substituted with generics.

@ConorO'Brien English?

@MDXF hey are you afk D:

@WheatWizard I don't know if you've found something shorter, but f [_]=true;f _=false should work I think, I don't know haskell very well yet though

@HyperNeutrino First one, but a full sentence parenthesized shouldn't appear inside another sentence, it should be on its own. E.g. This is a sentence (This is also a sentence.) written poorly. is wrong, but This is a sentence. (That is okay.) is good

That's just my opinion though

HyperNeutrino

Okay, thanks for your opinion. I think the general rule should be that removing all bracketed sections should maintain the correctness

Also, this will make the lack of a design look beautiful in comparison lol
