@ASCII-only idts?

yesterday, by Mr. Xcoder

CMC: Given an integer, find its prime factors. Then deduplicate the list and take its product again.

Conor O'Brien

oh huh

@ASCII-only Cheddar: (/:(*))+ @.unique + Math.factor

@ASCII-only btw do you have time to work on VSL today

@Downgoat yes

:D

but i think we should rewrite (again)

12:23 AM

ok brb logging onto c9

@ASCII-only I see long-term planning isn't a strong suit.

@Pavel no it's more issues with whatever framework we're using

~~Just write it in C#~~ like what issues?

@Pavel nearley is super slow, bison is annoying to make work without warnings

plus i want to do recursive descent so we can port almost directly to vsl

Huh

12:35 AM

Are quad trees faster than spacial grids? for collision detection

my collision detection falls to peices when I have 10,000 4 pixels objects, and one 40pixl object (spacial grid)

Why is this a pop-con?

Not sure, but it produced Some neat answers

@Tobi zufallsgenerator.github.io/2014/01/26/…

so apparently spatial grid for uniform sized objects, he doesn't say anything about different-sized ones

huh I thought more people would answer the fallout terminal question

@HyperNeutrino well it's only been three hours

12:42 AM

oh really? I thought it's been longer. Guess I should've checked the time ¯\_(ツ)_/¯

Patience, young Padawan

xD

@ASCII-only hashing falls apart with widely-varying sizes

I guess ill just stick to hashing

because I dont intend to have 1 40pxl object and 10,000 4 pxl objects

- thanks

anyone think a 3d lang is a good idea?

There already are some, so someone must think so :P

12:54 AM

@ASCII-only Yes

For example, my new language is probably not a "good idea" because it's just a cross between Python syntax and Java syntax and it's mostly for fun :P

@WheatWizard Not necessarily. Not all languages are made because someone thinks it's a "good idea" :P

1:21 AM

o lol I'm dumb

@HyperNeutrino ?

num = input() would be equivalent to (num = input)() because I had the [call] pattern matcher at a lower priority than the [binary operator] pattern matcher :P

rahuldottech

Hello

My parser kind of like a regex thing where it matches AST nodes and moves them into the right structure. It works a lot better than how Positron did it

(cc @ATaco) I made the unless syntax as you recommended :3 ([expression][unless][expression][expression|statement])

rahuldottech

@ASCII-only @MagicOctopusUrn @Mego where's you reach?

1:27 AM

Niiice.

@rahuldottech no where :|

I just realized that I've been working completely off of GitHub so like I have a backup from too long ago (as in about a day ago) :I

what how

ok name suggestions?

how is even possible did NASA put virus on their website ¬_¬

1:31 AM

NSA does what it wants. It doesn't matter how. They do not want you to know how because then you'll be able to sue them

/s :3

name suggestions for this new language? (cc @ATaco)

@HyperNeutrino Contact :P

...why?

@HyperNeutrino what language?

I can show you the syntax of some control flow constructs if you'd like. It's kind of a cross between Python, Java, and JavaScript

what really confuses me is that my binary operators are getting 4 arguments ;_;

anyway brb

oh ok

how about a snake from java

1:46 AM

Honestly Microsoft Excel should have default support for mass performing Regexes on cells.

@HyperNeutrino PythonScript

challenge idea: make that 05ab1e snake thing (05ab1e doesn't have a zero byte answer because it has the text at the top)

@ASCII-only eww no

Q: Are multi-method solutions allowed in Java?

Call it pudding pops

so I can say

actually it needs to be frozen pudding pops

I recently joined this community as a Java golfer, and I haven't been able to find a definitive consensus on acceptable solution formats for Java. From what I gather, the following are allowed (please correct if consensus is otherwise): full program (class definition with main method) full met...

@DestructibleLemon opls not this again

xddd

2:06 AM

oh huh that's weird

If you put an arbitrary number of unterminated single expressions around a binary operator, it will keep pulling the values in until they don't match around either side

so 1 2 + 3 4 becomes (+) (2, 3, 1, 4)

ha

fixed

that was liek the easiest bug fix ever

All I needed to do was add .rmType('binary_operator')

TFW you accidentally try to parse the interpreter in your language and it only fails at index 245 ;_;

Ha

how to programming language: a=1print(a)a+=1print(a)print(!a)a=0print(!a)

look ma, no spaces!

I need to take a break from what I'm doing. Anyone want to collaboratively design a language with me?

2:15 AM

Well, I'm working on Proton right now, and Business Cat had a 2D language idea.

Looks like he's not in the room :|

:I I know what the idea is though

Did you change the name of positrino? or is yhis a new language (or am I misremembering)

New language. Positron sucks. This one sucks less.

Ah not positrino

2:16 AM

The idea for the 2D language was to have the commands flip to their inverse every time the IP ran over it (input <-> output, add <-> subtract, etc)

@WheatWizard *positron

I guess positrino will be the next one :P

sure :P

@HyperNeutrino Ph cool, Klein has something similar to that.

@HyperNeutrino stop

@DestructibleLemon ;_;

@WheatWizard Oh interesting!

2:18 AM

Well thanks for the idea

yay after Jonathan Allan golfing my answer by 70 bytes to 662 I finally managed to golf... 1 byte... ;_;

@WheatWizard np, thank Business Cat later :P

I'll implement that real quick. And when Business cat finishes we can compare.

:P

I have to implement a bubble sort thing for a garfield edit I'm making

:P

feature-request: built-in mathjax support for Discord :3

2:22 AM

@HyperNeutrino This almost looks like maybelater code

a=1printa a+=1printa print!a a=0print!a (Although ! isn't properly implemented)

printa

How does that work

oh is print a statement?

Yeah.

I don't like that syntax personally (no variables can start with print) but ¯\_(ツ)_/¯ it looks more golfable

How does your parser/AST-generator/whatever work?

Like a very greedy Regex engine, basically.

ooh interesting that's basically how mine works :3

2:43 AM

would you like to see a sromg I bungled (not just one panel this time)?

sure?

Does anyone know WebRTC, by any chance

@Tobi I made a test/demo webrtc project but that's it

ive been searching, for 3 days, for a way to make a data channel between two users

I already know IP addresses so i dont need stun server

(I have IP address because they contact my back end)

How do I do this?

All examples are single page / same computer, not one has used IP addresses

2:59 AM

@ATaco what should ! do?

@Tobi without a server?

I have a server

then just use the server -> recieve -> send

magic

(thats how I receive their IP, and why I dont need stun servers)

i want fast peer to peer

and I dont have to host everyone

they can host eachother

also if this i just for chat there's friends for that

3:03 AM

I'll be similar to a tracker

It's game data

dat for a more complicated version if you don't want chat, it's like p2p git idk if you'll be able to use that just like add a file -> everyone else download it

ok...

jesus, Feross is all over npm

so... apparently my image is too big to use img.putdata

ffs

@Tobi yes he is (also all the other node gods)

3:05 AM

@DestructibleLemon What are you trying to achieve

I'm trying to use img.putdata to put the pixels into an image thing

he want to stanford and sold a p2p web server "replacement" to yahoo

Hmmm

An intresting problem

watched one of his talks

Anyway, how can i just make a simple data channel, I have IPs

@Pavel not really. I want to do it, and img.putdata says there's too many pixels

3:06 AM

I'm about to throw my PC out of the window

@DestructibleLemon Well, now you have to find an alternative to img.putdata

it's kind of weird that it just doesn't work

Do you have access it img.putdata's source?

You could increase the limit

well...

anyway I made a work around for this earlier anyway

@Tobi webrtc.github.io/samples/src/content/datachannel/datatransfer

3:08 AM

tried this page

its single page only

weird that it's a garfield strip that's too big

doesnt show how to connect to external client

or I could remove the lowest layer of the strip

@Tobi external client?

peer*

3:09 AM

nah I'll just have it add the last line with putpixels

ok it's done

@Tobi idk i thought it connected to peers via the server

I still cant believe this:

GIF

In browser!

@ASCII-only what u mean

@Tobi is that a human crush simulator?

owie

@Tobi look at the ice candidate parts

its supposed to be water

3:16 AM

those are the parts to setup the peer connection

backgrounds a bit too ligth

@Tobi 10/10 best water ever

@ASCII-only ill check

@Tobi doesn't look very realistic :P

i.gyazo.com/7f0b5d437f1cbb08143a0d1fec6d2b64.mp4

3:17 AM

how is it floating?

Yeah

its just like in alpha

GIF

that's not how water works xd

Lol :(((((

there would be way more movement than that

you can see the waves

and i have friction on

so it dies down

lemme turn off

3:19 AM

no, I mean by default water is doing heaps of moving and stuff

otherwise it would be a solid

^

@Tobi it looks like some sort of science fictiony super cooled gas thing

because water also isn't going to be compressible, like how it leaves gaps in this simulation

that said it is a cool toy probably

@DestructibleLemon looks more like a really empty ball pit to me

ok then

this is probably worse:

GIF

how do i make water?

3:25 AM

all the particles need to be moving

oh like random movement before hand?

like always

which would make it a lot more uniform as well (i.e. more like a liquid)

its because initially theres no kinetic energy

well more like a gas

@Tobi D: 0k initially

@Tobi >_> you shouldn't make kinetic energy magically appear

it appears from the users ball

movement

density 16x that of the water particles

3:30 AM

@Tobi this actually sort of looks like a human crush simulator a little bit though

i.gyazo.com/b32e077a3080d8a9bcd58ce03dce806f.mp4

is that more watery

GIF

oh in case you guys didn't know, esolangs.org is back apparently

@Tobi idk maybe

its mesmerising

also if you're gonna have friction, you need to convert it to heat energy

theres no heat in here lol

do u want evaporation?

3:32 AM

no, the heat makes the water particles move around heaps

that's what heat is

oh ok

so, friction is useless?

- in here

yes

there is some friction actually

but it gets converted to heat

remember to make total velocity the same before/after collisions, and give everything a random initial velocity

ive got the conservations sorted

but just need it to look watery

3:34 AM

you need some energy loss because you're moving around too

lemme lighten the background

what do you mean?

@Tobi don't make it too full

@Tobi if you move around = more total kinetic energy

so, loss in friction?

should it just be low, so it doesnt instantly die down?

yeah really low

GIF

do i need highlights

on, like, waves

thats advanced stuff

3:41 AM

not really

also hmm seems a bit crowded

should I increase particle size too, or only decrease density

what

why increase particle size

itll look deserted

@Tobi it's supposed to

have you guys ever made a thing that draws raster quadrilaterals given points on the grid?

3:43 AM

@DestructibleLemon ?????

prob have but dontr undestand what u mean

so, you know linedrawing algorithms?

like that but for a filled quadrilateral

@DestructibleLemon for what

@ASCII-only pixel graphics, you know

no but it doesn't sound hard

3:44 AM

i did that in openGL

@Tobi that's cheating :P

lol really?

i could do that in HTML5 canvas too :P

what is he talking about then

assembly?

Hello! Can anyone here solve this?

3:45 AM

I think he means modifying individual pixels

Helka Homba

How do non-programmers live without programming? Search and replace only gets you so far

I did individual pixels too

with canvas and webgl

(canvas' imageData)

I'm gonna make a thing that takes a bunch of points, a colour, then puts onto an image that quadrilateral, then does it again

@HelkaHomba Where have you been? You haven't posted a new challenge in ages! Well, it was just over two months ago, but it still feels like ages.

Anyone up for contact?

3:47 AM

you just want to draw rectangles on an image??

@Tobi yes

wht language?

@Tobi no...

quadrilaterals

oohhh

@DestructibleLemon how is that hard

3:47 AM

yeah just use points

um... because it's not as trivial as drawing rectangles

jeez man

stop bullying me ;)

Helka Homba

@R.Kap ppcg is a time sink so I removed the links from my bookmark bar, and yet I did not remove tnb from my autocomplete...

@DestructibleLemon you know what linear equations are right

um yes

@DestructibleLemon then just find the intersections

3:49 AM

is there a way to do the filling that isn't flood filling?

uh no?

@HelkaHomba Oh, I see.

why not...

do you think you can modify more than one pixel at a time

you could

split it into triangles

3:49 AM

>_>

@Tobi Please don't onebox heavy animated GIFs, let alone more than one. The combined GIFs you posted in the past hour weigh 77 MB, and there are still people with slow internet and/or internet billed by transfer. I've edited them down to links.

plus remember each line is separate

@ASCII-only hmmm

@HelkaHomba What about Youtube? I mean, I did notice you posting more often on your channel as of late. Or maybe it's just me...

@DestructibleLemon there are other ways but flood fill is already optimal

3:50 AM

@Tobi Mind phrasing that in a less offensive manner?

wait, I could just check each pixel is less than and greater than the linear equations

and then the line drawing thing is unnecessary

@DestructibleLemon wait what no that's too slow

that's not floodfilling

@ASCII-only wouldn't it be quicker than flood filling?

no

flood fill = calculate endpoints -> loop to fill

actually now that I think about it that might not work?

3:52 AM

@Tobi That is not less offensive.

What should I have said? cant edit any more

Helka Homba

@R.Kap I am doing that once a week steadily now, but just the Another Adventure series

@Tobi Excuse me sir. I, and many others, are quite offended by that term. Could you please refrain from using it (again)?

@DestructibleLemon for each pair (overlapping) y of intersections from lowest to highest y, calculate the x-values for the linear equations that matter

really?

3:53 AM

@Tobi "I'm not smart" or "I'm dumb"?

I thought mental retardation what slowness in the brain

@Tobi Literally anything that is not a medical condition. Cal yourself an idiot if you must.

actually I might use triangles

i think this is evidence that im an idiot

just because triangles are never concave or something

3:53 AM

@DestructibleLemon no :(

^

why not?

triangle lines (almost) never overlap

except degenerates

malformed*

because if you split it wrong you'll fill the wrong area

thats offensive

3:54 AM

...

degenerate triangle is the actual term

@Tobi No, "idiot" has to do with intelligence. The terms I think you are looking for is "ill-informed" or "ignorant".

@ASCII-only flood fill?

?

help I'm confused

just use my method :P

3:57 AM

no

you didn't even give a method

why not >_>

4 mins ago, by ASCII-only

@DestructibleLemon for each pair (overlapping) y of intersections from lowest to highest y, calculate the x-values for the linear equations that matter

I'm just gonna use this algo I found I guess

actually order doesn't matter

actually wait it doesn't work for certain cases

i can write a working one in pseudocode if you want

@ASCII-only how about this

no thanks

triangles xd
