Aiden Chow

@BgilMidol oh nice

is it even possible to get 1 trillion disbalance

DialFrost

possible

if ur a genius

Aiden Chow

@DialFrost nah its more like luck

you want to get as close to a straight line as possible on the bottom edge, but not exactly a straight line or else its not circular

allxy

279 billion disbalance

DialFrost

ah ic

i got 1 bil

HOW @allxy

2 bil

Aiden Chow

00:47

duuude i got 800 billion disbalance AGAIN

Aiden Chow

@lyxal bruuuuh and on an ipad too wtf

lyxal

00:56

@AidenChow nah that was my phone that time

Aiden Chow

u think its even possible to get one trillion

DialFrost

if u get it just right

Bubbler

Disbalance (lower=better): 4.656,201,108,698,998e+53

lol I just broke its number formatting

Aiden Chow

@Bubbler WHAT

weve just been utterly destroyed

Bubbler

let e = $('#SvgjsSvg1000');
let ev = $.Event('mousedown'); ev.clientX = 0; ev.clientY = 100; e.trigger(ev);
ev = $.Event('mousemove'); ev.clientX = 100000000000; ev.clientY = 100; e.trigger(ev);
ev = $.Event('mousemove'); ev.clientX = 200000000000; ev.clientY = 100.00001; e.trigger(ev);
ev = $.Event('mouseup'); e.trigger(ev); $('#btn_compare').click();

Aiden Chow

01:05

@Bubbler ok bruh

i was thinking of doing smth like that but i couldnt get it to work

i was doing CIRC.draw.circle(CIRC.pointRadius).move(100,100).fill('#7B92ED');

but it didnt analyze for some reason when i pressed analyze

DialFrost

@Bubbler my guys a genius

Aiden Chow

you could probably get NaN disbalance with that right

Bubbler

Golfed: CIRC.pointsArray = [[0, 100], [1e12, 100], [2e12, 100.00001]]; $('#btn_compare').click();

lyxal

@AidenChow one better: infinity

using 1e100 and 9e100 for the movements

Bubbler

Looks like it just becomes infinity if it hits around 1.8e+307

(f64 max is 1.something e+308 btw)

let e = $('#SvgjsSvg1000');
let ev = $.Event('mousedown'); ev.clientX = 0; ev.clientY = 0; e.trigger(ev);
ev = $.Event('mousemove'); ev.clientX = 5e76; ev.clientY = 0; e.trigger(ev);
ev = $.Event('mousemove'); ev.clientX = 12.041e76; ev.clientY = 1; e.trigger(ev);
ev = $.Event('mouseup'); e.trigger(ev); $('#btn_compare').click();

gives 1.7969e+307

Aiden Chow

01:25

how you do guys even find this code

Bubbler

open devtools, dig into event handlers, google "jquery trigger mousedown with coordinates", copy second SO answer, increase numbers, decrease numbers, binary search through numbers

DialFrost

uh wat?

Aiden Chow

@Bubbler ok that actually kinda makes sense

DialFrost

uh guys i didnt get my badge :(

lyxal

Which one?

DialFrost

01:38

sportsmanship

its ticked in the badges thing but i still have 4 silver not 5

Aiden Chow

01:51

why does converting to binary on desmos have to be so annoying :(

Bubbler

because desmos is not apl

3

Aiden Chow

rotating lists too :(((((((((

bruh the answers for the double bit rotation question are like 5-50 bytes, while im gonna be rolling in with a 100 byte desmos answer lol

anyone know if is there a way to make a list [k, k+1, 1 ... k-1] using modular arithmetic or something

Bubbler

02:12

If you start with 0..n-1, subtract 2, modulo n, and add 1 should do

Aiden Chow

@Bubbler oh huh really, lemme try that

Bubbler

If it doesn't (because it's JS-based I think?), add n-2 instead of subtracting 2

Aiden Chow

@Bubbler ok, that works, thank you very much

bruh that didnt save any bytes over my other version without mod :((

oh wait nvm it did, after some fiddling around

Aiden Chow

02:35

oh shoot it saved quite a bit of bytes actually, dang

@ophact the surprising thing is how the question isnt closed or deleted

PyGamer0

"The universe exists, therefore you can code." What I'm going to tell people who are too lazy to learn coding from now on.

PyGamer0

lol

PyGamer0

07:32

this is interesting

CMQ: Which is faster: type(x) == list or isinstance(x, list) ?

ophact

Sure seems like the former according to your link

Aiden Chow

@ophact hmm, sometimes, but it fluctuates for me

PyGamer0

^

Aiden Chow

for the last two lines, the former seems to be almost always faster, but for the first two, its not clear which one is faster

PyGamer0

i guess i will go with a type(x)==list check since thats faster

ophact

07:44

Would it be an interesting challenge to figure out why that is faster?

DialFrost

any feedback?

@PyGamer0 if[*x]==x

ophact

My guess for type(x)==list is that isinstance requires checking whether the reference is of the class list which requires time, whereas type simply requires checking if the "type" of an object is equal to the class list, and usually the type is explicitly stored as property

but I'm probably wrong

I have no clue about this sort of thig

thing

Aiden Chow

@ophact that sounds pretty reasonable

PyGamer0

@DialFrost uh nope that doesn't work

DialFrost

it does i think

emanresu A

07:50

^^

PyGamer0

^^^

DialFrost

^^^^

yikes -4

did i do something wrong

PyGamer0

maybe its too similar to the other challenge

Unrelated String

isinstance probably has to account for inheritance

/subclassing

Aiden Chow

@DialFrost try x=4 and [*x]==x

you will get an error

ophact

07:51

@UnrelatedString What inherits from list?

PyGamer0

@UnrelatedString yeah prob it does

ophact

@AidenChow I was the one who suggested it to @DialFrost. In their case, it was with strings and lists so it did work

but in general...

no

PyGamer0

@ophact your custom class

ophact

But in this case, you are trying on 4 and []

PyGamer0

if you have one

Unrelated String

07:52

hopefully not your custom class, granted, but your hypothetical custom class

it has to handle the possibility

ophact

In this case, it shouldn't matter whether or not inheritance is accounted for

PyGamer0

yeah i guess i will use the type equality check instead of isinstance

lyxal

@UnrelatedString which it does

Aiden Chow

OOP programming, this is getting a bit too big brain for me lol

PyGamer0

> Object Oriented Programming programming

ophact

Aiden Chow

@PyGamer0 oh lol, i forgot that OOP stood for that

ophact

PyGamer0

@AidenChow well "Python Object Oriented Programming" is POOP

lol

lyxal

@ophact Smh my head

ophact

07:55

Is the type of an object stored though?

It's perfectly possible...

Unrelated String

python's type system VERY distinctly does not support type erasure lmao

so it is most certainly stored

ophact

That's another possible cause of its better performance

When I made my language, I think I would determine the type of an object to perform operations

Unrelated String

because it can just compare the stored type by equality instead of checking if the target type either is it or subclasses it

removing at least a branch and who knows however much else logic

Aiden Chow

well dont you need to check subclass sometimes? like i think boolean is a subclass of integer of im not horribly mistaken?

PyGamer0

yes boolean is

you can convert it to a int like int(True)

Aiden Chow

@emanresuA what exactly is a userscript, never really got what that was

emanresu A

08:12

tampermonkey.net

Ok nvm that doesn't provide a lot of expalnation

But basically it's a piece of JS that runs on certain sites as they load.

Aiden Chow

@emanresuA ok what is it telling me to install

pxeger

a userscript is basically a way of writing a simple browser extension but without all the complication of a whole actual browser extension

emanresu A

^

pxeger

you just write a file of JavaScript which gets executed on certain pages upon load

Aiden Chow

@pxeger so there isnt really much of a difference between a userscript and a full fledged browser extension in terms of functionality?

pxeger

08:15

full browser extensions can have their own individual pages (e.g. moz-extension://[some UUID]/index.html), which isn't really possible with userscripts

Adám

Userscript

A userscript (or user script) is a program, usually written in JavaScript, for modifying web pages to augment browsing. Uses include adding shortcut buttons and keyboard shortcuts, controlling playback speeds, adding features to sites, and enhancing the browsing history.On desktop browsers such as Firefox, userscripts are enabled by use of a userscript manager browser extension such as Greasemonkey. The Presto-based Opera-supported userscripts (referred to as User JavaScript) are placed in a designated directory. Userscripts are often referred to as Greasemonkey scripts, named after the original...

so how does using a userscript affect a website, are they mainly just used for quality of life changes

PyGamer0

yeah

pxeger

In practice, they're generally just for that kind of small thing, yes, but in theory you can have a userscript do as much as you like

Aiden Chow

08:24

@pxeger huh ok, so someone can potentially make malicious userscripts for ppl to use?

how do u know something like that website emanresu sent doesnt contain malicious stuff

PyGamer0

because its made by CGCC members (which probably arent malicious)

and you can check the userscript yourself to check if it contains fishy stuff
