hi

is Prime Fractals in Pascal's Triangle as a challenge alr dupe?

Probably not an exact dupe, but it's just a trivial combination of pascal's triangle and primality testing, so it'd be a dupe of both IMO

DialFrost

oh

so cannot okey

Fmbalbuena

What happened?

DialFrost

how bout binary neural network

Fmbalbuena

@DialFrost Off-topic

DialFrost

00:14

?

Fmbalbuena

@DialFrost This is off-topic

ta Radvylf srik su shilani

No it is not

If it were a code golf challenge

Fmbalbuena

@taRadvylfsriksushilani Yes, because No AI, No neural network, except puzzle-solving

ta Radvylf srik su shilani

@DialFrost There's only six questions tagged neural-networks, so that or something similar might be a good challenge idea

@Fmbalbuena DialFrost is suggesting a challenge where you implement a neural network

That is on topic as long as it has an OWC

Which is presumably code-golf

DialFrost

ye

thejonymyster

00:23

what would the neural network be doing

DialFrost

actually i changed my mind nvrm

it was orgnigally to solve binary texts of 8 bits but nah

sigh SE is down

thejonymyster

i cant believe SE is down again

if it gets downed again it wont get up... ;_;

DialFrost

haha

Stackstatus is useless

DialFrost

i agree

emanresu A

While things like github status make an effort to track outages within a few minutes, you're lucky if stackstatus has added it within a week of the outage ending.

Well duh, it's a human run blog, not an automated testing system

DialFrost

anybody here a js golfer

ta Radvylf srik su shilani

I am

emanresu A

Me too

Although I have a maths exam soonish

DialFrost

haha

math is fine

Time Complexity Using performance measures carried out on the execution time of the programs for a new computer, your mission is to determine what's the most likely computational complexity from a family of fixed and known algorithmic complexities. Example Here is an example of performance measur...

@taRadvylfsriksushilani i made it so its more readable for now

ta Radvylf srik su shilani

Make Math.log a variable, you use it super often

(L=Math.log)(...) the first time, and L(...) the rest

Final semicolon is unneeded

Infinity -> 1/0

DialFrost

ic

ta Radvylf srik su shilani

X[X.length-1] -> x.at(-1) (won't work on TIO without a polyfill in the header)

DialFrost

polyfil???

ta Radvylf srik su shilani

01:04

Array.prototype.at=function(index){return this[index>0?index:this.length+index]}

And that goes in the header, it's free

Since it's in newer JS versions but TIO's not up-to-date

Lots of var a=...;var b=...;, when var a=...,b=...; is a lot shorter

Define all your vars at once at the top if possible, since the commas save 3 bytes each

DialFrost

oh

ta Radvylf srik su shilani

I'd make Math.log(n) a variable in addition to Math.log, since you use it so much

Those for loops can definitely be shortened. I'd use recursion, but if you don't want to do that, some clever rearranging of the statements can save a few bytes

Instead of function, use arrow functions

E.g., l=(X,Y,f)=>...

Also, taking X and Y as parameters is pointless since they never change

Just have it take f=> and use the X and Y already in scope

Anyway, gtg, but there's a lot of golfing still possible

DialFrost

ye sry im bad

thx anyways!

Someone tried to do a little trolling

I presume the idea was that people would google blue waffles to get an idea of what that guy was talking about

Okay

Ugh pyodide takes ~40s to load

Stackstatus is useless

Aiden Chow

huh, something strange happened. i tried to type in the chat but it said i was logged out, even tho i didnt log out myself

Fmbalbuena

@AidenChow How do you post???

Aiden Chow

@Fmbalbuena i logged back in

it was really strange though, it showed i was logged in but at the same time i couldnt post any messages

Fmbalbuena

@AidenChow ok

ta Radvylf srik su shilani

02:33

@AidenChow Has to do with the outages SE's been experiencing

Aiden Chow

@taRadvylfsriksushilani yeah, i figured

ta Radvylf srik su shilani

I've had that happen before too, not sure why it only occurs during some outages and not others

DialFrost

can anyone check if i have fufilled @WheatWizard 's requirements for my challenge retaining water? (sandbox)

Fmbalbuena

@DialFrost Which requirements?

DialFrost

check comments under the challenge

its the first one in sandbox

Fmbalbuena

02:40

Really I can't see

Aiden Chow

@Fmbalbuena this one: codegolf.meta.stackexchange.com/a/24425/96039

Fmbalbuena

@AidenChow Really Really I can't see

emanresu A

CMQ: Would you use an online interpreter that took a minute or too to load

DialFrost

no

depends actualy

Fmbalbuena

@emanresuA I will use, If there is no interpreter to the lang X but the interpreter Y is only interpreter to run X blah blah blah X Y X X Y X Y X Y.

DialFrost

02:42

if the code is massive then fine, if not then screw it

Aiden Chow

probably not

emanresu A

Hmm okah

out of memory?

ugh wasm is pain sometimes

Fmbalbuena

@emanresuA I should use, if this needs 2 YB ram or something

emanresu A

@emanresuA Context: I have a couple of wasm python runtimes that take 20-40s to load

Aiden Chow

i have no idea what wasm is so I probably won't be interested in loading it

Fmbalbuena

02:46

@emanresuA ThEn YoU caN UsE iF tHeRe Is oNLy 1 iNtERpeTER

@emanresuA Hey, I have a question; I have a question: I have a question. I have a question, Is wasm assembly?

@sku Welcome to TNB, you can talk anything except some rules

thejonymyster

@AidenChow what is your pfp a picture of

caird coinheringaahing

@DialFrost WW is saying that instead of A, B, etc., you should just allow a 10x10 matrix of positive integers

I'd suggest just removing anything mentioning taking input as letters if you choose the matrix, as it'll just lead to confusion

Also, please add in a worked example

^ To potential challenge writers: I cannot emphasise how useful a worked example is for clarifying your challenge. It can be difficult to get the words to describe some tasks, but a step by step "this is how X transforms to Y" is almost always easy to do, and understandable. Realistically, when posting a draft in the Sandbox, you should include a worked example before posting

caird coinheringaahing

03:31

@taRadvylfsriksushilani So, I decided to mess around with the graphs you showed for some of my slowest answers, and found that they almost (as in, within 0.004 on n, and within an order of magnitude for O(f(n))) cross all at the same point: desmos.com/calculator/ctrlz5lqry

No idea what's special about n = 4.67, but it seems at tho (n^2)!, 9^(n^2) and 2^(n!) all have approximately the same value (as in, all 6.<something> * 10^(20)) at that n

ta Radvylf srik su shilani

omfg I just wrote some 2d collision code from scratch and it worked first try

thejonymyster

you need to try to break it to be sure

ta Radvylf srik su shilani

@cairdcoinheringaahing Probably just coincidence, but that's pretty cool

emanresu A

03:55

@taRadvylfsriksushilani Have you tried colliding two objects where one's moving faster than the other's width per tick?

DialFrost

how do i caculate the alphabetical order of the puzzle

my brain ded

ta Radvylf srik su shilani

@emanresuA I'm kind of cheating for my game's projectiles. They just hit their target instantly, which is why the collision code was a bit difficult. I wasn't just moving it forward in tiny increments based on its speed and checking if it was in a box, I had to check if the line it traveled in would intersect with the target at all.

DialFrost

for my challenge retaining water

cuz ww and caird asked me to change to 2d list of int

emanresu A

@taRadvylfsriksushilani Oh lol. is this for amidst or something?

Or the zombie game?

ta Radvylf srik su shilani

No, a new one. A team-based top-down tank game where you can customize your tank's stats.

emanresu A

Hm, cool

ta Radvylf srik su shilani

So for example, you could put all of your stats into speed, and quickly reach your opponent's flag. But if they've invested more heavily into armor and gun damage, you wouldn't stand a chance.

I'd be happy to beta test at some pont

> The word swastika comes from Sanskrit: स्वस्तिक, romanized: svastika, meaning "conducive to well-being". In Hinduism, the right-facing symbol (卐) is called swastika, symbolizing surya ("sun"), prosperity and good luck, while the left-facing symbol (卍) is called sauwastika, symbolising night or tantric aspects of Kali. In Jainism, it is the symbol for Suparshvanatha – the seventh of 24 Tirthankaras, while in Buddhism it symbolises the auspicious footprints of the Buddha.

@cairdcoinheringaahing i fixed it

tried my best but its prob still the same

for the challenge

emanresu A

04:33

And... accidentally leaked two gigabytes of memory.

DialFrost

guys alittle help

given a 2D list of ints

how do u get the minimum value of the outer layer

so basically if input is this

1111
1001
1111

the minimum value is 1

59394
50004
44444

Bubbler

Iterate horizontally twice, iterate vertically twice, and take the minimum of the four

DialFrost

minimum value is 3

thejonymyster

how come the minimum isnt 0

DialFrost

is there a way to one-liner it

the outer layer @thejonymyster not the inner

Bubbler

04:35

You could but it would be pretty long

thejonymyster

oh wait i understand what you mean now

DialFrost

the most outer layer

oh

emanresu A

Ok, it turns out vscode live-server has a ~~bug~~ feature where memory is cached across live reloads

hyper-neutrino

@DialFrost in what language

DialFrost

python3

emanresu A

04:38

max([*a[0],*a[-1],*map(a,lambda v:v[0]),*map(a,lambda v:v[-1])])

(Untested)

hyper-neutrino

i have lambda m:min(m[0]+m[-1]+sum([[x,y]for x,*_,y in m],[]))

emanresu A

@hyper-neutrino Wait python can do destructuring like that?

hyper-neutrino

yep

DialFrost

i think hyper got it correct!

that was fast my guy

having trouble solving a problem that i posted

...

the retaining water one

yikes

emanresu A

TIL you need some somewhat cursed Python to get stream output...

(import js, yikes)

PyGamer0

04:44

welp today is my holiday

@DialFrost APL must have a one liner for this

DialFrost

?

PyGamer0

APL <-> A Programming Language

emanresu A

Python has a one-liner for everything

exec(...)

PyGamer0

o_o

haax

hyper-neutrino

without cheating via exec, python is actually turing complete on one line

emanresu A

04:48

Fractran?

PyGamer0

@hyper-neutrino lambda?

hyper-neutrino

well ofc you use lambdas

@emanresuA wdym

emanresu A

Nvm

thejonymyster

if my lang doesnt have variables, and i already have comparison, what should i have the equals symbol do

DialFrost

anyone here can do a port for me from python to c++

hyper-neutrino

04:49

depends what you want

DialFrost

cuz i had to use c++ due to 1 annoying part of the challenge

thejonymyster

i thought about having it be eval, but that seemed like more trouble than it's worth

DialFrost

current code:

thejonymyster

oh wait i know how i would make it work

DialFrost

tinyurl.com/333wm7f8

anyone can port this to python ^ it would my life so much easier thx

this code in ungolfed for readbility at the moment

PyGamer0

04:54

@DialFrost i think i got it: {⌊/((⊣⌿,⊣⌿)⍵),(⊢/,⊢⌿)⍵}

DialFrost

...

PyGamer0

@DialFrost well what does that code do?

hyper-neutrino

^, also i thought you wanted python to c++ lol

DialFrost

bruh haha

i can translate nearly all of it

except 1 part i forgot

i accidentally deleted my code

shld i post retaining water?

or issit still not refined (question)

PyGamer0

@hyper-neutrino probably because:

> do a port for me from python to c++

thejonymyster

05:06

i changed my mind eval is way too hard

emanresu A

05:19

TIL python dicts are quite different from JS objects

Great, I need to create some sort of python repr in JS...

ta Radvylf srik su shilani

I'm taking the RTO prototype prototype down for tonight

emanresu A

Aww....

ta Radvylf srik su shilani

It's not really meant to be used at this point

emanresu A

True I guess

ta Radvylf srik su shilani

I think it's giving the project a bit of a bad first impression, given the incredibly unfinished UI, lack of any languages other than JS, and janky bot Ginger made

OISB should be better hardened down, with more languages, in about a week. At that point I'll start on an actual UI, but until then I don't want much more attention being given to the prototype.

emanresu A

05:27

When are you planning to launch?

ta Radvylf srik su shilani

March 1st

Well, for OISB 1.0.0, at least. RTO might trail behind by a couple weeks so I'll have time for UI stuff

emanresu A

You might want to do it a day or two earlier - user's bounty for most langs is "end of february"

ta Radvylf srik su shilani

The proto will win then :p

Planning on having 20-40 languages by late feb

We should get the start files (the biggest thing holding us up on adding more languages) finished by the middle of this week, at which point I'll be able to add new languages at a rate of like one every ten minutes

im always curious:P so thanks for that

@emanresuA are you trying to make python in JS O_o

in flax, 3 hours ago, by Fmbalbuena

@PyGamer0 but Probably you need API to use semver

You don't

@PyGamer0 No, I'm trying and mostly succeeding to use python in JS

Although interfacing is cursed

Unrelated String

i can imagine

PyGamer0

×_>

Aiden Chow

@UnrelatedString yeah, probably 3 or 4 years ago

not too sure why they took it out

it was a lot of fun to play around with

Unrelated String

wacky

PyGamer0

@emanresuA why

Unrelated String

05:49

i want to say i got the impression that google hangouts was already half dead 3 or 4 years ago but considering they haven't removed it from the gmail interface or outright google +'ed it i don't know why i want to say it's dead

emanresu A

Or more accurately, you need some sort of interface

PyGamer0

some of my friends use hangouts

thats why its not dead

Aiden Chow

@UnrelatedString i think it's pretty much dead, i think more people use google chat now

not too sure, because i personally moved on to discord

emanresu A

But not necessarily, say, a REST api like api.stackexchange.com

Unrelated String

...
google chat?
yeah i've never even heard of google chat lmao

i never really used hangouts to begin with since i never really had friends until i got added to a league of legends group skype that then migrated to discord when discord became a thing

Aiden Chow

05:52

@UnrelatedString google chat is literally google's version of discord but worse, thats all you need to know

Unrelated String

amazing

the only time i've seen google chat mentioned

is in a video about scammers that try to destroy large youtubers' channels
