@orlp Oh, that's an interesting thought. "Up" is defined as "in the plane of the planets, anything pointed toward X feature."

Seems reasonable.

oh no where is up ヽ(。_°)ノ ¯\( ͡° ͜_ʖ ಠ)/¯

@MartinEnder I was going to do a challenge, but actually found a duplicate. :)

hi @orlp

mh, is there no rooms for cjam?

nope

or well, I don't believe there is

9:07 PM

wondering if there's some kind of any and/or all builtin.

Could reduce with & in the worst case scenario...

Dr Green Eggs and Iron Man

Holy crap, I'm almost at 200 today.

GG :)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@orlp i approve

Dr Green Eggs and Iron Man

Maybe I should write a challenge just so I can get to the cap. :)

LegionMammal978

Just curious, who's hosting ppcg.lol?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

9:10 PM

Quill IIRC

Dr Green Eggs and Iron Man

I think it's Quill

Ninja

code design question: I'm making a maze generator for a generic map. Should the generator take a map without any points, and add points in a maze-like fashion, or should it take map with lots of points, and remove connections to make it a maze?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@FryAmTheEggman did you make progress, if any, on the leaderboard for my challenge? I forgot if you said you would

LegionMammal978

I wonder how long it will be kept up for, I've been using it recently as a PPCG URL-shortening tool...

@NathanMerrill what kind of properties do you want from your maze

9:12 PM

well, its actually independent of the algorithm. I plan on using lots of algorithms (including wall adders and wall removers)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@LegionMammal978 it's definitely quill

the question is whether its better to add nodes (and the connections between them), or to use existing nodes and remove the connections

bost.ocks.org/mike/algorithms/#maze-generation

@CᴏɴᴏʀO'Bʀɪᴇɴ Oh, no I totally forgot :( I'm probably going to be rather busy this week, but if I get a chance I will.

@NathanMerrill what was it?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

9:14 PM

@FryAmTheEggman okai :3 no rush

@orlp oooh, pretty. I'm not positive if I'll be able to do that one (because I don't enforce a 2D map (or a square map either), but I'll look into it

Q: Tiling, given vertex configuration

Task The task is to tile polygons, given a vertex configuration. Scoring Your score is equal to the "complexity level" your submission reaches. Complexity levels are cumulative, meaning that to reach #3 you must also support #1 & #2. Submissions at an equal complexity level are distinguished...

code-challenge graphical-output geometry tiling

@orlp oh, I was looking at the wrong section. Funny enough, I'm working on that algorithm (using it as my design "test")

(The spanning tree algorithm)

@orlp those loop-erased random walks look like they'd make a good challenge.

yeah, I've never seen that algorithm (and I've done a lot with maze generation)

that said, it has a O(infinite) maximum runtime

@NathanMerrill so does uniform random number generation if coprime with 2

Eᴀsᴛᴇʀʟʏ Iʀᴋ

We need a LQP recommend deletion reason for invalid answer.;

9:25 PM

strawpoll.me/10779625

@Downgoat the initializer because there might be multiple

@orlp you can still have multiple with optional args

@EᴀsᴛᴇʀʟʏIʀᴋ LQP?

yes I agree

31120551 indeed

So no way to get stack element type in CJam :(. aw

9:26 PM

@Downgoat in the class because its easier (and you can define alternate constructors/default params)

Low Quality Post?

@Downgoat you misunderstand me

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@zʏᴀʙiɴ101 low quality post

Image(std::string filename) and Image(const std::istream& file) for example

@orlp ok. I just want to descide this now because I'm starting on class tokenizer and itll be difficult to change it later

9:28 PM

@Downgoat I still prefer it in the class declaration

and just use secondary constructors

if they do have different types

@NathanMerrill can you give me an example?

I like it with the class but idk if that'll work

LegionMammal978

I'd say in the initializer

Do you ever hide in the bathroom when you are sick at work but you made it all the way to the very last hour while managing to remain productive?

@Downgoat kotlinlang.org/docs/reference/classes.html

Because I just did and it actually made me feel good enough to continue working for another twenty minutes. But now I feel crappy again.

LegionMammal978

9:31 PM

@Rainbolt ...

Just in case you were having gross thoughts, our bathroom is impeccably clean, and I wasn't actually using it.

El'endia Starman

@Rainbolt "crappy" <_< ... I (figuratively) see what you did there.

That was an accident and now I see why Legion said "..."

I'm bad at puns

LegionMammal978

> our bathroom is impeccably clean

Now that's surprising.

@Rainbolt I'd consider somebody who makes puns without trying is quite good at puns

9:34 PM

That's my secret. I appear modest but really I am trying hard

so are you modest or good at puns? :)

@NathanMerrill hm. i don't completely understand this. If the arguments are with the class, then where is the "primary" constructor?

that is the primary constructor

@NathanMerrill I have no witty response. I really need to go home

lol

clearly modest

9:39 PM

closes Chrome tab titled "modesty puns - Google Search"

@Rainbolt my trick is to play Nethack and every ten minutes alt-tab between all the windows and shake your mouse like crazy

bonus points for a dramatic sigh

class Image(file: Stream){
    constructor(filename: String){
        this(File(filename))
    }
}

I don't think I can do that at work. I've never played Nethack though. Is it text based or something?

Yes. There are graphical tilesets but those are for heretics.

@Doorknob if I use wingdings instead of the standard font, is that ok?

9:42 PM

I enjoyed the text based version of Minecraft that comes with the ComputerCraft mod. If it's like that then I would probably enjoy Nethack

@NathanMerrill Uhhh... if anyone managed to do that and not quit after 10 minutes, I'd be impressed.

Oooh! Let me kill that bell!

@Rainbolt yeah, it's a textbased console game, it's good fun when your power goes out or you have no internet

wait, it works even when your computer doesn't have power?

woah

that's quite a game

@NathanMerrill On a smartphone.

There is a NetHack android app.

9:45 PM

ah, I play the heretic version called Pixel Dungeon

er

@zʏᴀʙiɴ101 There is? I've played on my phone, but by SSHing into the public server.

I haven't had a laptop since college, and I probably never will

I don't need portability, and it seems like you pay more for portability

well, I used to not have a smartphone, so if I needed any internet outside of home/work/school), I needed a laptop

10:26 PM

a while ago I used to play CS that much that some of the guys that I used to play with started calling me Quill offline

Dr Green Eggs and Iron Man

Woah, quills real name isn't quill?

It's impossible to tell whether a single sample is truly random or not

@Mego better

Anonymous

Randomness is a quality of populations, not of individual samples

10:42 PM

'random' is simply a property that any amount of samples does not possess

also wrong

randomness is a quality of a process, not its result

Why are you using that syntax? String b = 'test' would be a lot clearer.

no not really

and see:

Most vexing parse

The most vexing parse is a specific form of syntactic ambiguity resolution in the C++ programming language. The term was used by Scott Meyers in Effective STL (2001). It is formally defined in section 8.2 of the C++ language standard. == Example with classes == An example is: The line is seemingly ambiguous, since it could be interpreted either as a variable definition for variable time_keeper of class TimeKeeper, initialized with an anonymous instance of class Timer or a function declaration for a function time_keeper which returns an object of type TimeKeeper and has a single (unnamed...

I'm not trying to reinvent C

and that syntax is really odd imo

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat error should be Attempted to make variable b a <type>, expected <type>

Anonymous

10:48 PM

@Downgoat Don't have function declarations. Assuming you can call a function before it is defined in a source file, declarations are completely unnecessary.

@CᴏɴᴏʀO'Bʀɪᴇɴ ok that's better

Cᴏɴᴏʀ O'Bʀɪᴇɴ

maybe ...variable "<varname>"

?

I think of V as very similar to retina. It is a golfing language, but it's only good at certain types of challenges. For other types, it's even longer.

vim is very different from retina

pls tell me how to edit file in retina

Dr Green Eggs and Iron Man

ik but it's similar in that it's occasionally great for golfing and occasionally terrible.

Q: Generate the Rummy Sequence

Your task is to take an input n and output element n of the Rummy Sequence, a sequence which I made (looking on OEIS will not help you). Definition Each element of the Rummy Sequence is a set of truthy or falsey values. Ex.: [true, false]. The steps to producing a member of the Rummy Sequence ...

@CᴏɴᴏʀO'Bʀɪᴇɴ what is the shortest way to concat two arrays in JS?

[].concat(a1, a2)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat [...a,...b]

@CᴏɴᴏʀO'Bʀɪᴇɴ that's not shorter than concat ;_; you see anyway to golf this? :3 I'm sure the .fills can be golfed >_>

11:23 PM

@Downgoat Can't you just add them?

I thought the point of weak typing is that you could do cool things like that

> [1] + [1,2]
< "11,2"

well that's pretty dumb

hrm

JS: The cons of weak typing with the cons of stong typing. what could go wrong!

So it just casts the arrays to strings? laaaaameeeee
