development

[quartz kindle]

how about instead of a ladder

a tournament with groups and shit

[frosty gale]

now you have LLMs as well so the bots can trash talk

[quartz kindle]

lmao

[crystal wigeon]

Lmao

fr I could do that

And make the bot more engaging

but I need to train the bot for my game context

and I have no idea how to do that

[crystal wigeon]

There are occasional tournaments help by different guilds

But again they feel the bot is not balanced / not good enough yet

Sadly that’s the price I have to pay for leaving too many bugs for prolonged period

Anyway playerbase rn is slowly depleting and I see no hope

So I’d rather give to some game dev who can maybe make few sensible changes and revive it

Or I just quit

[quartz kindle]

tough position

[crystal wigeon]

Yeah any balancing change I make is seen as nerf and people quit

I can’t change the mentality frfr

Now that i think about it there was no reason for me to make it exponential buff. It was balanced as it but since nobody was using it and they kept complaining I killed that skill I made this dumb change

[quartz kindle]

sometimes if a change is needed for the health of the ecosystem, a sacrifice is unavoidable

you will lose players, but you will have a chance of getting new, more satisfied players

[crystal wigeon]

Not if it kills off the entire playerbase

It’s more like the players physiology is weak. They think 400k damage is normal and when I balance it out they start spamming that I killed the game myself lol just cause they don’t wanna try something new or balanced

All the trolling takes a mental toll ngl

I wanna get this over with fr

[quartz kindle]

you dont need to engage with them

game devs and game companies rarely interact with players

they just post updates and go home

[crystal wigeon]

But at the same time it has also prevented by bot from growth

[quartz kindle]

then look at metrics

not what peoplesay

[crystal wigeon]

Yeah I’m looking at metrics too

the metrics are what people say here in this case

[quartz kindle]

thats not good for your mental

[crystal wigeon]

Cause these guys are the ones engaging with new players

And then they drive them away ish

[quartz kindle]

if they are so invested in the game, then why not ask them to balance it for you

or make a voting system

[crystal wigeon]

I did that’s where the exponential buff came

[quartz kindle]

well

now they see what happened to the game

so they can rethink as well

[crystal wigeon]

Welp not entirely but I just thought of it based on some suggestions that’s all

Now if I change it. They’ll say it got too nerfed

Schrödinger cat

Anyways

idk why I’m also struggling to get like new players too tho

Bot hasn’t grown at all

Despite doing all the auctions on topgg

Welp

Ig it’s just not good enough

[frosty gale]

sometimes throwing more money isnt the solution

there are a bunch of factors that correlate to player count

[crystal wigeon]

Mhm

I agree if the game isn’t good enough it’s hard to attract new players

[frosty gale]

mostly boils down to how appealing your bot/page/ad/etc is to the player looking at it

the average person looking at your ads is probably just browsing for something completely unrelated and random so you really have to attract their attention

and also use the right tags ofc

[crystal wigeon]

mmm

[frosty gale]

but thats only one part of the problem, the second is actually getting the person looking at the ad to actually get and use the bot

im not an advertising or business expert but i would take a step back and look at what you can improve and ask yourself would you play/get this bot

ask for your players opinions as well, polls, suggestions, etc

they are the ones playing after all

[green kestrel]

what can you do to make the bot different

there are so many clones of idlerpg

and they all follow the same tropes of card collecting, anime characters, etc etc

what did you do to make it different, make note of that and make that the thing you emphasise on ad campaigns and on your bots page

on my bots webpage I explicitly call out how all these bots are the same in my FAQ and that my bot isn't anything like them

you have to stand out

I'm sure you already do, because if people wanted more idlerpg and more epic RPG they'd just play those bots, they're playing yours so it means you have something unique

[slim dirge]

Finding a niche concept gives you an edge, for sure.

[green kestrel]

most people probably already have one and aren't telling anyone that needs to know

[lament rock]

My bots aren't like the others. Mine are shitty and break down for no reason. Give money so I can totally fix that and make the bot usable :)

[inner heart]

i sumbiited my bot but that time my bot offlined anyone can say why

@green kestrel

[deft wolf]

What

[inner heart]

@deft wolf can you come to vc

[deft wolf]

No, I can't

[inner heart]

@deft wolf bro i sumbited my bot to topgg but that time my bot offlined

i cant start my bot

\

saying like this

@deft wolf

can you help me

[deft wolf]

No

[inner heart]

what bro

plz help

[harsh nova]

No clue how pterodactyl works but it sounds like some other service is running that can't run concurrently with the discord bot

[green kestrel]

don't run discord bots in pterodactyl

it's not made for that it's made to host game server instances

just use a plain vps

and the fact it's called "my first bot" perhaps means it isn't ready for prime time yet, you didn't even give the project a proper name

[frosty gale]

overpowered buffs clearly

honestly if people are happy over them currently and making money id just keep the change

but introduce more subtle changes that balance the game out more later on

cash cow per se

[green kestrel]

yeah don't remove your bread and butter feature

have you considered making the really big buffs premium feature?

(this for hoax)

[frosty gale]

from the sounds of it at the moment he doesnt have the people to spare to make these changes that upset the user base that is actually paying you

tough spot really

[green kestrel]

premium feature: massively op enemies that need huge buffs, huge buffs in the premium

hmm, wait, you need multiple people to maintain a bot????

first I heard of it

[frosty gale]

im tempted just to make a panel specifically designed for hosting discord bots/node apps/python apps and give it away for free just so people stop fucking using pterodactyl

[green kestrel]

at least, when it comes to source, I've never trusted anyone but myself

[green kestrel]

do it but don't restrict it to just those two langs, build it around docker

I would recommend it for dpp too if it was bundled with it

[frosty gale]

not a bad idea actually

i would of course do it around docker

basically the standard for container apps anyways

[green kestrel]

yeah

[frosty gale]

since i do security i can probably also harden it pretty well as well

[green kestrel]

I think people are using pterodactyl because cheap Minecraft hosting is readily available and that's what they all use, part of the problem is removing that interia

if they have to self host your bot platform it won't ever replace ptero

someone would have to offer it at the same price point as the cheap Minecraft boxes

most people using it aren't in the position to self host it

[frosty gale]

yeah thats what i thought

youd mostly be marketing it to panel hosts

cheap ones at that usually

i also see the pterodactyl containers for bots usually fail quite quickly and come up with some error

and the average developer using this likely wont know how to fix the issues

ill think about it

its definitely a promising project to add to a portfolio

and i could design it pretty well given ive been in the exact position like 5-6 years prior using pterodactyl for a bot without knowing what im doing

[green kestrel]

I tried to use pterodactyl to self host a Minecraft server

I hate the thing

it tried to take over my entire server

[inner heart]

Bro thats a free host

[green kestrel]

it doesn't work if you do other things on the server too

[green kestrel]

...you get what you pay for

[inner heart]

I dont have money

[green kestrel]

running a bot costs money

[inner heart]

Ooo

But bro that host giving 24/7 support

The bot running in that host properly but i submited here my bot gone to offline

[deft wolf]

Then contact their support

[inner heart]

@green kestrel

[green kestrel]

I'm sure that they really really give good 24/7 service for free

contact them, they'll fix it for sure

[slim dirge]

You're using the same host provider as me I think lol

If it is, they have a Discord support server linked from their website. You can open tickets there for help. I opened one recently for perms issues and they sorted it

[inner heart]

Ooo you using opticserver i see thank u bro

[surreal sage]

How can I properly merge a pr so that:

doesn't appear

[surreal sage]

aint forcing

[slim dirge]

Try git pull origin dev if you're using cmd line. Then git push.

[wind copper]

Can anyone help me in this stuff

[lyric mountain]

did u receive any email regarding it?

you were probably locked out of verification for that app for some reason

[wind copper]

Nope bro

[wind copper]

What the heck bro

[lyric mountain]

what is your app about?

is it a bot or a game?

and did you get it from some template?

[wind copper]

It's a bot

[lyric mountain]

and the other 2 questions?

[quartz kindle]

i dont think theres anything wrong

just scroll down and fill out the forms normally

[quartz kindle]

do you have a valid ID or passport?

[lyric mountain]

ah lmao, I misread this as a "your app EMBEDDED cannot be verified"

[quartz kindle]

you are embdedded

embededededded

[lyric mountain]

that's just discord verification, and they dont get your personal data either way

[quartz kindle]

embededashion

[lyric mountain]

no u 🔄

eh, yk they already have any and all data they might want about you right?

[quartz kindle]

they already know

they just dont care for 90% of the cases

speaking of which, i still need to do my taxes

says the guy with a rainbow clown cartoon cat profile picture

[crystal wigeon]

The Linux backdoor made news lol

https://youtu.be/bS9em7Bg0iU?si=jSpzDTBAwgiPvOCG

[wind copper]

Tes

What should I do now

[quartz kindle]

then just do what it says

fill out the forms

you can ignore that warning

[coral phoenix]

what about the eop exploit that rarely anyone is talking about https://github.com/Notselwyn/CVE-2024-1086

wild

[crystal wigeon]

I think there was a similar exploit for su

[past field]

is it possible to attach photos to command?

[lyric mountain]

just supply the info it asks for

you'll need to verify your identity through stripe, so you'll need to either do it yourself or get someone older than 16 to do it for you

then there'll be the technical data about your bot, such as infrastructure and data collection policy, hope you paid attention during development else you'll struggle on this part

[slim dirge]

Congrats on getting to 100 servers! definitely an achievement that you should be proud of!

[pale vessel]

god bless bro

[eternal osprey]

my bot is still verified but not used lmao, anyone know what to do with it?

I am thinking about rebuilding the bot to a crypto bot

[frosty gale]

turning your bot into a crypto scam bot is definitely a good next step idea

[slim dirge]

That's the million $ question, coming up with an idea that'll attract lots of users

[eternal osprey]

😭 ain’t no one talking about scams

[eternal osprey]

Yeah I got something cool in mind .. do I need to do a manual verification on topgg again or something if I make such a heavy revamp of my bot?

[frosty gale]

why does discord need ID again when verifying a bot

[quartz kindle]

you guys ever heard of a DOW attack?

denial of wallet

xD

[slim dirge]

I think (though correct me if I'm wrong) that they're wondering, if their bot undergoes a complete revamp and becomes a bot that does something totally different to what it was originally verified on, if top.gg needs to reverify it.

[lament rock]

It likely comes down to data privacy and insurance. Bots are hosted on their platform and they're trying to allow bots to have deep integration with it. So much so that users probably wont think too much on the fact that an app is operated by a third party. If their data was being collected by this third party and they're exposed online, then Discord could get in big trouble. This way, they have collateral and can hold malicious actors responsible beyond banning their account and can get authorities involved.

My bot got denied verification because it retains user's data until the user requests a deletion. (just user IDs)

[sharp geyser]

[quartz kindle]

when verification first came out, i said my bot stores user data for 1 year

and still got verified

im guessing verification got much stricter with time

[lament rock]

yeah

[digital swan]

thats insane wtf

[lament rock]

exactly that

Hey papiophidian,
 
Unfortunately, after looking it over, I have decided to deny your verification request. This is due to the duration in which you retain discord data. Do not fret, though! We will reconsider this verdict if you implement stronger data disposal processes and reapply for verification!
 
Furthermore, if you require additional assistance while using the Discord app, you can easily contact our Customer Experience team at any time. You can reach them at https://dis.gd/contact.
 
I'll go ahead and close this case as solved, but please reply to this ticket if you have any other queries, and I'll be pleased to assist you.
 
Cheers,
Davis

Hey Davis,

I had a question regarding the specifics of what I'm storing since I only store user IDs. Having to delete user's settings and economy data unless the user explicitly wants me to might suck for if they wanna keep that. How long do you suggest I should even retain this info for?

Hello papiophidian,
 
Thanks for writing back!

[quartz kindle]

well, i've seen people simply reapplying without changing anything

and eventually they get it lol

[lament rock]

I thought about lying but I dont want to

I guess it could help for people who abandoned and forgot my bot

would be a lot of data just left in the database unless they request deletion

but how I see that is a problem for me to solve if it comes to that

[eternal osprey]

Instead of user id, save a generated string instead that can be converted using a certain hash function

Technically it ain’t an id no more 🤷🏽

That way you only store the generated part but can still benefit from the perks of having a user id

[wheat mesa]

The point of a hashing function is that it's one-way only

If he needed those IDs without the actual known user, he wouldn't have a way to get it

[past field]

I wanted to create an egg hunt around my server that will have the post randomly post eggs around certain channels, once a player finds it,they reply to it with the 🥚 emoji and they will get 1 point. the bot then announce the amount of points a player has and hides another egg. this loops until the score to win is reached, the bot announces the winner in the channel the command was invoked and then it deletes all the egg emojis that it put.. can someone look over this code and tell me what I could change on it?

even though i'm sure this is stupid.

[wind copper]

Bot verified bro

Oh already done

[wind copper]

Bot verified

[wind copper]

Thanks bro

Lol 😂

I verified last night

[modern sable]

yea, iirc i had to delete (or rather anonymize) data within 30 days of them leaving the server or something

[quartz kindle]

economy bots according to discord:
didnt access your account in 30 days? gg you lost all your money

[lyric mountain]

your ultra rare one-of-a-kind item? too bad, where were you for the last 30 days?

[radiant kraken]

just make a game at this point

[eternal osprey]

yeah

an encoding type of system where we store a sort of 'hash'. I didn't really mean an actual cryptographic hash function.

but even then, it would be possible if he would store the private keys

that way the data is confidential and the id is only released and read ocne it's needed after solving the hash

[lyric mountain]

but that's how any password-based encryption works

you simply store a hash of the password (because you shouldn't store plain text pass) and use that to encrypt whatever data you want to

you dont "solve" the hash, you decrypt the data

[eternal osprey]

my textbook says solving hashes

we solve a hash using a private key

[lyric mountain]

that's pretty wrong in the technical sense

[eternal osprey]

thats what they refer to as decrypting a hash using a function and private key

[grim aspen]

could be an older term

[eternal osprey]

idk it's an old book

forgot from who it was

[grim aspen]

figured

usually the older books are outdated

[lyric mountain]

IT study material shouldn't even be books anyway

unless it's a language documentation

and even then it's iffy

[eternal osprey]

I don't study IT though

[lyric mountain]

java bible for example gets a new release every so often

[grim aspen]

computer science?

[eternal osprey]

yessir

[lyric mountain]

IT as in any code-related topic

[eternal osprey]

To be fair i barely did anything that has to do with coding or something

in these past 3 years i only did theory after theory

[lyric mountain]

that's code-related

[eternal osprey]

is it?

Majority where math classes

i don't see that closely related to code

[lyric mountain]

it is, you dont need to build houses to learn architecture

[grim aspen]

math is used in coding

[eternal osprey]

yeah i know it is

but many of the things i am kearning rn will be useless in the future

like 80% of my courses

[lyric mountain]

if you stay in the IT area it'll help understand things you search for

like how I should've paid attention to matrix classes

[radiant kraken]

why

[eternal osprey]

yeah true, matrices and vectors are hella useful.

[lyric mountain]

because I need to do matrix stuff for game dev

[eternal osprey]

Especially when creating games

[radiant kraken]

ah

like physics?

[lyric mountain]

tho godot is helping a lot tbh

[eternal osprey]

probably movement

[lyric mountain]

translation/rotation calculation

[eternal osprey]

do you use it a lot for collision physics as well?

Idk how it's done in practice, i know the theory tho

[lyric mountain]

kinda, as my collision hitboxes aren't axis-aligned rectangles

but I can use point-inside method for detecting hits

nonetheless I'm using godot now, so I dont need to do it myself anymore

[eternal osprey]

laziness will end the human race

[radiant kraken]

ah icic

thanks!

[lyric mountain]

lul not laziness this time, I needed to do it to be able to compile to web

[eternal osprey]

no jk, it's good that you use something to do it for you. The calculations are hella hard

[lyric mountain]

so I could migrate my tcg to discord activities

[eternal osprey]

ahhh

[lyric mountain]

the ship game is nearly ported fully, just need to finish the first boss and implement the other player ships

https://sb.shirojbot.site if u wanna see it

the source code is public I believe, spacebreach on my repo

nvm it was private, now it's public

[radiant kraken]

damn godot is a bit slow

[lyric mountain]

that's my vps probably

tho it does get faster on subsequent loads

[radiant kraken]

me after pressing play

[lyric mountain]

lmao

ah that's the music loading probably

I didnt make loading screens yet

[radiant kraken]

rewrite your game in vanilla js

[lyric mountain]

💀

ok just checked it myself, that delay ain't normal

[radiant kraken]

oh btw

the game loaded

but it's like 10 fps

[lyric mountain]

lemme check vps htop

odd, nothing unusual

I'll restart nginx

[eternal osprey]

the game looks awesome

though are you sure your matrix calculations are correct?

[lyric mountain]

well, I'll need to look up what's the fps issue

game was working normally yesterday

[eternal osprey]

I am shooting while standing still and my bullet curves heavy to the left each time

[lyric mountain]

on a side note, how tf did someone reach 38k score

[radiant kraken]

i did inspect element /s

[lyric mountain]

the bullet should move in a linear path according to your current angle

if it's curving something is wrong

[eternal osprey]

i think there is, the hitboxes are also not entirely accurate i think. i hit that mf like 5 times on the sides

[radiant kraken]

does your game lag?

[eternal osprey]

the game is really cool tho

[eternal osprey]

yeah a lot

[radiant kraken]

oh i thought it's just my browser lol

[lyric mountain]

I'll try reuploading it, perhaps it solves the issue

the game was supposed to run 60 fps, as it was earlier

[eternal osprey]

@lyric mountain are you using projection matrices for the hitboxes and checking whether 2 points align on the same coordinates? If yes i suggest increasing the width, so the x, of the numerator.

cuz i keep hitting that ship but it aint dying

i can literally see my bullet go in his sides.

[lyric mountain]

the lag might cause collisions to be skipped

if it's physics processing lag, that is

[radiant kraken]

do you have the game as a standalone application?

maybe it being in the browser could cause some of the lag issue

[lyric mountain]

compiled no, if you have vstudio I think you can run from the project tho

[radiant kraken]

my laptop cant run visual studio

[lyric mountain]

I'm having it too, started lagging today

uploading the binaries again, I'll clear cf cache just in case too

[past field]

if anyone has a moment to take a look and give me feedback 😅

[lyric mountain]

well, it's lagging less but still subpar

[lyric mountain]

what issue are you having?

[past field]

it doesnt award the user who found the egg the last point, so it doesn’t announce the winner or delete the eggs. it just keeps posting the eggs in the channels

[lyric mountain]

yep, it's definitely a vps issue, the same code runs pristine if I host locally

[lyric mountain]

does it send the "found the easter egg" message?

[past field]

yes for every egg except the winning point

[lyric mountain]

I'm on mobile for a while so I can't check, but how are you checking if it's the winning point?

[lyric mountain]

Put some console.log or message before those resolves to see whether it's reaching them

[wheat mesa]

Use quadtrees for collision

[lyric mountain]

That's out of my reach on godot

[wheat mesa]

They’re easy to implement and will give you a massive increase in performance compared to the naive O(n^2) attempt

Oh

That’s fine then

Thought you were still working on your engine of sorts

[lyric mountain]

Also the lag is happening because slow resource streaming probably, as the lag disappears when I host locally

I need to find a way to fix that

[lyric mountain]

I was, but ported to godot for activities

[past field]

ok i’ll do this

[surreal sage]

💀

for a 65% keyboard

💀

[lyric mountain]

Oh lmao I just noticed

I can host the game on gh pages

[lyric mountain]

Aight, found some possible fixes, I'll try in a moment

[quartz mortar]

Nah

[surreal sage]

1 in 150 though

[quartz mortar]

The max i paid for a 65% is like 120€..

[green kestrel]

is that an April fools

id never buy anything other than a full size with numeric keypad

[past field]

wait now that i’m looking at this

[past field]

where i put the check for required points to win… should that be AFTER the end of round collector? or does it matter?

[spark pebble]

Am I tripping or did I wake up to FUCKED up embeds?

Why is this shit on 2 lines? I swear it never used to be.

[lyric mountain]

just another tuesday for discord

every feature is broken every once in a while

[spark pebble]

I hope it's a feature and not an update

[spark flint]

no

it was announced today

[sharp geyser]

Unless they are late with the joke

[timber hatch]

if anyone is able to help that would be great. firstly, it's worth noting this is only happening in production and was not happening in testing. but upon authentication, it doesn't return the session until the user gone onto another page and refreshed. (NextJS + AuthJS (formerly Next Auth)

the component you're looking at:
[redacted]

my _app.js (i've seen some people say this might be the issue?)
[redacted]

my next auth callback
[redacted]

[humble gyro]

yo that site looks sick

[timber hatch]

thank you my man, would be great it it was functional too :(

[humble gyro]

hahaha yea

i haven't used authjs

how do you manage your sessions?

for next-auth you could set it to jwt and avoid needing any backend session tracking

[timber hatch]

lemme take a look

my first time using both nextjs and authjs (formerly next auth) so still ropey

[humble gyro]

yea fair

[timber hatch]

pog fixed with refetchOnWindowFocus={true} on the sessionprovider

[silver jackal]

Onebump on top

[timber hatch]

sorry about him

[silver jackal]

[frosty gale]

id just write my own

and if you use the argument that you can mess it up and leave a vulnerability you can do the same by using authy

even moreso id say because youre putting in less care overall

[past field]

according to the console log, the end of the round is registering and the winner has been determined

[lyric mountain]

then the issue is where you're checking promise result

[past field]

// Wait for a user to find the egg or timeout
                const collected = await new Promise(resolve => {
                    collector.on('collect', async (reply) => {
                        // If a winner is already found, do nothing
                        if (winner) return;

idk what’s wrong with it then lol

i don’t get one

[quartz kindle]

1. thats not how you return inside a promise, nor inside an event

2. you're trying to reinvent the wheel, discord.js already has a built in method to do exactly that

[past field]

tim man i’m sorry 😭😭😭😭😭

[past field]

i didn’t know that though 👀

[quartz kindle]

what type of collector is that? messages or interactions?

or reactions

[past field]

messages

[lyric mountain]

@radiant kraken quick question, what browser did u use to run the game?

some people are saying edge runs fine while chrome has heavy performance issues on it

[radiant kraken]

edge

[past field]

hmm ok, i will try this

[wheat mesa]

holy moly webdev is awful, just had to make this duct tape solution for something I'm trying to do ```js
window.onload = () => {
const element = document.getElementById("term-user-input");
element.addEventListener('keydown', event => {
if (event.key == "Backspace" && element.innerText.trim() == ">") {
event.preventDefault();
}
})
}

[open cedar]

Hi

[proven lantern]

is there a built-in function in JS that will only filter out undefined items in an array?

[lyric mountain]

dont think so, but you can always prototype it

[proven lantern]

if i did that i would overwrite the functionality for filter() with no params. it would filter out undefined by default. i would probably need to copy over the original filter() code just to modify it. i never modify the prototypes

[lament rock]

0 is a falsy value

I wouldnt overwrite it unless you arent using any third party libs

You can always make your own prototype

Array.prototype.filterUndefined = function(callback) { return this.filter((i, ind, arr) => i !== undefined && callback ? callback(i, ind, arr) : !!i) }

[proven lantern]

Array.prototype.__originalFilter = Array.prototype.__originalFilter ?? Array.prototype.filter;
Array.prototype.filter = (callbackFn, thisArg) => {
    if (callbackFn === undefined) {
        return Array.prototype.__originalFilter(a => a === undefined, thisArg)
    }
    return Array.prototype.__originalFilter(callbackFn, thisArg)
}```

[humble gyro]

[lament rock]

Libs may expect the original behavior. Overwriting isnt good

[humble gyro]

function notNull<T>(value: T | null | undefined): value is T {
  return value !== undefined || value !== null;
}

my favourite way to do this

const values: (number | null)[] = [1, 2, null, 4, 5];
const filteredValues: number[] = values.filter(notNull);

[sharp geyser]

Now make that a js lib and you’ll make bank

[humble gyro]

sorry i already had a security article made about me this month

[radiant kraken]

or
return value != null

[humble gyro]

[sharp geyser]

Yea and there will be another

[humble gyro]

sadge

[radiant kraken]

how

[sharp geyser]

We don’t speak about it

[radiant kraken]

🤨

Imagine a function that accepts a list of numbers and returns two lists of numbers, where the sum of the numbers in the two lists are as close as possible. is it possible to write that function so it's 100% accurate without checking every combination?

i have this unit test that compares everything i write against the brute force method and i keep failing

this is my attempt not using brute force

// return two lists of numbers, where the sum of the numbers in the two lists are as close as possible
function splitNumbersEvenly(numbers) {

    // sort the number list input
    numbers.sort((a, b) => a - b);

    // initialize two list arrays
    const list1 = [];
    const list2 = [];

    // add numbers alternately to list1 and list2
    let i;
    for (i = 0; i <= numbers.length - 4; i += 4) {
        // add the first and last numbers to list1
        list1.push(numbers[i]);
        list1.push(numbers[numbers.length - i - 1]);

        // add the second and second-to-last numbers to list2
        list2.push(numbers[i + 1]);
        list2.push(numbers[numbers.length - i - 2]);
    }

    // add the remaining numbers
    for (let j = i; j < numbers.length; j += 2) {
        list1.push(numbers[numbers.length - j]);
        list2.push(numbers[numbers.length - j + 1]);
    }

    // return the balanced lists
    return [list1, list2];
}

module.exports = splitNumbersEvenly;

bit of a weird use case but was wondering if anyone could help...

• my users make a request from nextjs frontend to nextjs backend with some params.
• the backend makes a request to /pdf-template which is on the fronend (with the params)
• the pdf template is updated with the params
• puppeteer turns it into a pdf and returns to client

my issue is when i have "I'm under attack" mode enabled on cloudflare. The puppeteer request gets captcha. I tried changing the configuration rules to: ip src add !== vercel deployment ip but that did not work.

any tips?

[quartz kindle]

is pdf-template ever accessed directly by users?

in any case, you can probably access it internally using localhost:port/pdf-template

[timber hatch]

it's "technically" public but will redirect to root if the header we set in backend isn't there. and since users will never know what that header is then

[quartz kindle]

your attempt is good, there is something more you can add

as you add the numbers to the arrays, keep track each array's total score

on every number, check how that number would affect each score, and add to the lowest scored array

at the end you can walk through the arrays just a little to even out any large score discrepancy

or even just walk through the numbers backwards, from highest to lowest

[proven lantern]

mmkay, i'll give that a try. thanks!

// return two lists of numbers, where the sum of the numbers in the two lists are as close as possible
function splitNumbersEvenly(numbers) {

    // sort the number list input
    numbers.sort((a, b) => a - b);

    // initialize two list arrays
    const list1 = [];
    const list2 = [];

    const numbersCopy = [...numbers];

    // iterate over the numbersCopy array while it has elements pop
    // the first and last elements and push them to list1 and list2
    // respectively
    while (numbersCopy.length) {
        const listOneAverage = list1.reduce((acc, curr) => acc + curr, 0) / list1.length;
        const listTwoAverage = list2.reduce((acc, curr) => acc + curr, 0) / list2.length;

        // if the average of list1 is greater than the average of list2 then push the highest number
        if (listOneAverage > listTwoAverage) {
            list1.push(numbersCopy.shift());
            list2.push(numbersCopy.pop());
        } else {
            list2.push(numbersCopy.shift());
            list1.push(numbersCopy.pop());
        }
    }

    // return the balanced lists
    return [list1, list2];
}

module.exports = splitNumbersEvenly;```

the brute force is still finding better lists that are closer

AI came up with this magic

function splitNumbersEvenlyOptimized(numbers) {
    const totalNumbers = numbers.length;
    const halfTotal = totalNumbers / 2;

    let minDifference = Infinity;
    let result;

    // Iterate over all possible bitmasks for the first list
    for (let bitmask = 0; bitmask < (1 << totalNumbers); bitmask++) {
        if (countSetBits(bitmask) !== halfTotal) continue; // Skip if the number of set bits is not halfTotal

        const list1 = [];
        const list2 = [];
        let sum1 = 0;
        let sum2 = 0;

        // Distribute numbers based on the bitmask
        for (let i = 0; i < totalNumbers; i++) {
            if (bitmask & (1 << i)) {
                list1.push(numbers[i]);
                sum1 += numbers[i];
            } else {
                list2.push(numbers[i]);
                sum2 += numbers[i];
            }
        }

        // Calculate the difference in sums
        const difference = Math.abs(sum1 - sum2);

        // Update the result if the current difference is smaller than the minimum difference
        if (difference < minDifference) {
            minDifference = difference;
            result = [list1, list2];
        }
    }

    return result;
}

// Function to count the number of set bits in a number
function countSetBits(num) {
    let count = 0;
    while (num) {
        count += num & 1;
        num >>= 1;
    }
    return count;
}

module.exports = splitNumbersEvenlyOptimized;```

[quartz kindle]

that code is prettybad performance wise

[quartz kindle]

huh interesting, at first glance its very hard to understand what it is actually doing, how were the results?
also, that only works if the total sum of either array is less than 32 bits

can you show your brute force version as well? im in the mood for some benchmarking :^)

[proven lantern]

here's the brute force

function splitNumbersEvenlyBruteForce(numbers) {
    const totalNumbers = numbers.length;

    // Generate all possible combinations of indices for the first list
    const combinations = generateCombinations(totalNumbers);

    let minDifference = Infinity;
    let result;

    // Iterate over each combination and calculate the difference in sums
    for (const combination of combinations) {
        const list1 = [];
        const list2 = [];
        let sum1 = 0;
        let sum2 = 0;

        // Split numbers into two lists based on the current combination
        for (let i = 0; i < totalNumbers; i++) {
            if (combination.includes(i)) {
                list1.push(numbers[i]);
                sum1 += numbers[i];
            } else {
                list2.push(numbers[i]);
                sum2 += numbers[i];
            }
        }

        // Calculate the difference in sums
        const difference = Math.abs(sum1 - sum2);

        // Update the result if the current difference is smaller than the minimum difference
        if (difference < minDifference) {
            minDifference = difference;
            result = [list1, list2];
        }
    }

    return result;
}

// Function to generate all combinations of indices for the first list
function generateCombinations(totalNumbers) {
    const combinations = [];
    const halfTotal = totalNumbers / 2;

    // Recursively generate combinations
    function generate(current, remaining, start) {
        if (current.length === halfTotal) {
            combinations.push(current.slice());
            return;
        }

        for (let i = start; i < remaining.length; i++) {
            current.push(remaining[i]);
            generate(current, remaining, i + 1);
            current.pop();
        }
    }

    generate([], Array.from({ length: totalNumbers }, (_, i) => i), 0);
    return combinations;
}

module.exports = splitNumbersEvenlyBruteForce;

the optimized one is twice as fast for me

[quartz kindle]

can you also paste your test function so i can copy it

[proven lantern]

test('test', () => {

    let bruteForceTimeAccumulator = 0;
    let optimizedTimeAccumulator = 0;

    // run 100 times with random numbers

        const randomNumberFn = () => Math.floor(Math.random() * 800) + 800;

the initial array is always even?

[proven lantern]

yeah, i plan to use it to balance teams based on player Elo ratings

so like a 5v5 game. it will alway be even

[timber hatch]

does anyone here use resend for emails?

[quartz kindle]

the brute force function time seems to grow exponentially depending on array size lmao

[proven lantern]

when i use a list of 30 number or more it runs out of memory

[quartz kindle]

lmfao

99 iterations of array4 takes 1ms

99 iterations of array16 takes 380ms

array18 takes 1800ms

array 20 takes 8000+ms

array24 took 162194ms

lmao

[quartz kindle]

what is the maximum team size?

[proven lantern]

12v12 would be the biggest

[quartz kindle]

alright

[proven lantern]

24 total numbers

[quartz kindle]

the AI version is indeed faster, but still horribly slow

200ms at 16
3600ms at 20

24 still running lmao

[proven lantern]

it's slow, but i think it's the only thing that gives the correct result

[quartz kindle]

87000ms for the 24

99 iterations

[quartz kindle]

that cant possibly be the most efficient way to do this

[proven lantern]

i know. there must be a better way

[quartz kindle]

i need to help a bit at home, so brb, but i'll experiment a bit with it

[surreal sage]

I ran sudo ip addr add public.ip.here.123/255.255.255.0 dev enp2s0 on my ubuntu 22.04 server

for some reason, all connections outside the local network (192.168.*.*) are timing out

ip addr show enp2s0

blurred/24 = public ip/24

[quartz kindle]

i see the gist of the problem now, i really cant think of a much better way than brute forcing if you want the best possible match

but i think the bruce forcing can be optimized

[proven lantern]

I'm still confused by what the ai did to optimize the brute force code.

I guess the ai code is still brute force, but doing some bitwise trickery

[quartz kindle]

it seems to be a known problem

hey yall i need a stupid easy developer-oriented question for my work for verifying developers

nothing too difficult, something that a developer of any experience should be able to get correctly

[radiant kraken]

can you give an example?

[sharp geyser]

Fizz buzz

:)

Or Fibonacci

[radiant kraken]

idk fizz buzz

never wrote a fizz buzz code before

[sharp geyser]

It’s simple

[sharp geyser]

https://hatebin.com/prkisuqlbp

for x in range(1,101):
    if x % 3 == 0 and x % 5 == 0:
        print("FizzBuzz\n")
    elif x % 3 == 0:
        print("Fizz\n")
    elif x % 5 == 0:
        print("Buzz\n")
    else:
        print(f"{x}\n")

[radiant kraken]

i see, thanks!

[sharp geyser]

actually I can make this better by not doing an addition of x

cause iircyou can set where it starts in range

but im too lazy

:D

[radiant kraken]

mhm

[sharp geyser]

fixed

but yea thats how you do fizz buzz

its relatively easy

[radiant kraken]

[sharp geyser]

fibonacci is s omething even I don't know how to do tbh

[quartz kindle]

i was able to optimize the AI version by about 20%, but still sucky yucky

1 second for a single function call is ridiculous

honestly i would just go with a naive version and not care about teams being slightly uneven

lmao

i didnt try the leetcode versions yet, they will likely be faster

[past field]

@quartz kindle you are a genius!!!!

ok the game runs exactly how I wanted it to!!!

the only issue is when invoking the command i get "application did not respond" but the command does run like it's supposed to, and I don't get any errors in my terminal

when i use the command, it sends a message to the channel letting people know the game started.. I'm guessing that response is not within the 3 seconds.. so I changed it to an ephemeral and it worked fine - no error.. but I wanted the response to the command to be a channel message that everyone sees so that they know the game has started

[quartz kindle]

show code

[past field]

god i'm nervous now lol

[quartz kindle]

the main problem is that you're receiving an interaction and responding with a normal message, not with an interaction reply

[past field]

ohhhhhh

[quartz kindle]

you could simply change the first response The Easter egg hunt game has started! to interaction.reply()

also, a suggestion

save the egg messages in an array

[tough coyote]

Wana make a bot with me

[quartz kindle]

so you can directly delete them afterwards, without needing to fetch messages

eggs.push(await randomChannel.send("🥚"))

Promise.all(eggs.map(egg => egg.delete()))

[tough coyote]

Dm me make bot

With me

[quartz kindle]

no thanks

hm, this actually makes more sense

right now i have hit the max of 5 components, but i need 5 more..
Or is it not doable?

[craggy pine]

You can create another row of buttons if you wanted it on a single embed.

[eternal osprey]

i have hit 5 rows already

which is the component max iirc

[deft wolf]

Holy

[craggy pine]

[eternal osprey]

no

[craggy pine]

or 20 whatever the limit is

[eternal osprey]

i tried to categorize them in diff rows lmao

but that's not needed

each row holds like max 2/3 buttons

[craggy pine]

let row = new ActionRowBuilder()
let row2 = new ActionRowBuilder()

add 5 buttons to row 2?

Then components: [row, row2]

miyuka i know, i was having a brainfog moment

what i did is categrize each button section into a new actionrow

[wooden ember]

just wondering;
I have trash internet, I was testing a few things on a web page I was making but if I show it to my mates over the internet it loads like ass because even lowrez images tank m,y 0.8Mb/s upload. I had the idea I can just upload the image to discord and link it from there to save on my bandwidth. However it still loads sorta slow, is that still my internet also having bad download? Or is that cuz it downloads the image from discord to the web server and then gets reuploaded to the client?

[quartz kindle]

there are literaly tons of image hosting services you can use

as well as free webhosting services in general like github pages

[wooden ember]

yeah but I'm testing this one thing and I will forget about all this in the morning

just an idle curiosity really

this is literally it.

was messing with transparency effects

thats just a b/w baground image but with an orange background colour on top of it that is opaque

originally I was wondering if it would mean I would save on file size but thats dumb cuz an orange and white image will use the same space as a black and white image does(probably)

[quartz kindle]

transparent images usually cost more space than opaque images

and generally, colorful images also cost more space than simple images, with less colors and less complexity

other than that is depends on image format, encoding and compression

[frosty gale]

i would imagine it would be about the same? since its technically a color

unless you need some other data to figure out which pixel is transparent and which isnt

[frosty gale]

so they can still be compressed no problem no?

[quartz kindle]

in the sense of rgba vs rgb

1 extra byte needed for transparency

[wooden ember]

the image isnt what is transparent its an orange overlay that is done purely through css so no space used for that

well exept for the bytes for the line in the css file I guess

[quartz kindle]

that would probably help saving bytes yes

if your imageis pure black and white, you can also use a format that uses indexed colors

for example PNG8

idk if webp also does that by default

[wooden ember]

I have no idea its just a png I found on the internet

[quartz kindle]

png8 basically has a maximum of 256 different colors and uses an index table to lookup colors

so instead of being 3 bytes per pixel, is just 1 byte per pixel

[wooden ember]

one of the few tiling pcb traces images I could find that was hard to see if it was tiled but also interesting

[quartz kindle]

it can be further reduced

[wooden ember]

ooo nice

[quartz kindle]

if you have a color index with only 2 colors, technically each pixel can use only 1 bit

but idk if png can be slimmed down that far

The standard allows indexed color PNGs to have 1, 2, 4 or 8 bits per pixel

[wooden ember]

I know nothing about image formats other than jpg is for printing and png is usually for digital stuff

and gif is for the funny moving images

[quartz kindle]

jpg is a "lossy" format, which means it doesnt store all pixels, but only key pixels

and reconstructs the image by guessing the missing pixels from its neighbours

[wooden ember]

it also sucks around curves

[quartz kindle]

png is lossless, which means all pixels are saved

[wooden ember]

yeah

[quartz kindle]

then you have bit depth, aka how many bits per pixel

jpg is usually 24 bits, aka 3 bytes per pixel

png has variable depth, which can go as low as 1 bit per pixel, for pure black and white images

webp has both modes, lossy and lossless

lossy webp is similar do jpg, but with a lot of improvements

lossless webp is similar to png, but also with a lot of improvements

[wooden ember]

interesting

i've been going back and forth on this. another thing i need to worry about is memory usage. i'm running the code on 128MB lambdas and it takes about 450MB to use the brute force method with 24 numbers. the optimized version barley uses any memory so it's actually possible to use that. and lambdas are pretty cheep. it would cost about $0.0000021 each time i run that function(if it "only" takes a second)

[quartz kindle]

dont they charge for cpu time tho

1000ms of "cpu time" is not a small amount

[proven lantern]

let me see

this is their pricing page im looking at
https://aws.amazon.com/lambda/pricing/

[quartz kindle]

idk about AWS, but like cloudflare workers limit instances to 10ms of cpu time per request

[quartz kindle]

well, i guess you need to try it and see how it affects your billing :^)

[proven lantern]

that's the aws way

Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 1 ms*. The price depends on the amount of memory you allocate to your function. In the AWS Lambda resource model, you choose the amount of memory you want for your function, and are allocated proportional CPU power and other resources. An increase in memory size triggers an equivalent increase in CPU available to your function. To learn more, see the Function Configuration documentation.

i wonder what this means and are allocated proportional CPU power and other resources

[quartz kindle]

it means the more memory you give it, the more cpus and etc it will come with

[proven lantern]

but i wonder if they limit the time like cloudflare

it seems like a lambda that is running idle would cost as much as a lambda running at 100% cpu usage

but that doesnt make sense

[quartz kindle]

they dont run at idle

once the request is done, the instance is shut down / sleeps

[proven lantern]

i mean a lambda that is waiting for a sleep() before it shuts down

function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}```

[quartz kindle]

ah no, that doesnt count as cpu time

idk lambdas, but cf workers are limited by time as well

30 seconds per request

[eternal osprey]

hey, a designing dilemma here again!
Is this okayish looking?

[proven lantern]

lambdas have time limits too. they use to be lower, but they can go up to 15 minutes

[proven lantern]

what is that circle to the bottom left of the input form doing?

[eternal osprey]

it's an animated background

[sharp geyser]

It’s a star

[eternal osprey]

i added stars in

hollon

[sharp geyser]

Also if it’s animated

Make a gif

[proven lantern]

trickery

[sharp geyser]

💀

Can’t ask for opinions on something you aren’t showing fully

[eternal osprey]

there ya go

[proven lantern]

that star doesn't look like the others

[sharp geyser]

Looks fine but that border shadow is a little much

[eternal osprey]

yeah i have to tone it down a bit

[sharp geyser]

Could be a comet

[eternal osprey]

nah

that's a bug

but tbh, a comet sounds good

[sharp geyser]

I was helping you out

[eternal osprey]

whahahha

thank youu!!

[sharp geyser]

But nah it looks fine

[eternal osprey]

What do you guys think of the black form? Does it match with the dark purple?

[eternal osprey]

i see, thanks for the feedback!

[sharp geyser]

Are you making this for @quartz kindle 2034 astrology api

[eternal osprey]

No, it's a discord bot i am trying to create a site for.

[sharp geyser]

I know I was kidding

[eternal osprey]

what's this tho

[sharp geyser]

An api Tim has been saying he’ll make since 2020 or before hand

[eternal osprey]

relatable

got so many unfinished projects

[past field]

ok so when storing messages in an array to be deleted at the end of a game.. is it possible to set it to delete any message that contains a specific emoji?

i’ve been trying to do that and it isn’t deleting the messages

[quartz kindle]

yes

[sharp geyser]

You can filter through the messages of a channel

Or if you have them in an array

See if they contain the emote

[past field]

i may not have done it correctly then

[sharp geyser]

Hard to say without knowing how you’re currently doing it

[past field]

let me get it

so long story short, i created an egg hunt game that sends eggs around the server, and @analog patrol gave me the idea to have the eggs stored in an array so that it’ll be deleted after the game, but there’s another message that tells the users who found the egg when it’s found.. i tried to also have that in the array to be deleted and now it won’t delete, so i added the egg emojis to that message so that the bot will save every message containing the egg emoji and delete it afterwards

idk if that makes sense

[analog patrol]

I did? lol

[quartz kindle]

wrong tim lmao

[analog patrol]

figured heh

[past field]

oh 💀💀💀💀💀

not me thinking you changed your pic 💀

[proven lantern]

can i see your code for this?

[quartz kindle]

function splitNumbersEvenlyOptimized3(numbers) {
    const totalNumbers = numbers.length;
    const halfTotal = totalNumbers / 2;

    let minDifference = Infinity;
    let result = Array(halfTotal);

    // Iterate over all possible bitmasks for the first list
    for (let bitmask = 0; bitmask < (1 << totalNumbers); bitmask++) {
        if (countSetBits(bitmask) !== halfTotal) continue; // Skip if the number of set bits is not halfTotal

        let sum1 = 0;
        let sum2 = 0;

        // Distribute numbers based on the bitmask
        for (let i = 0; i < totalNumbers; i++) {
            const x = numbers[i];
            if (bitmask & (1 << i)) {
                sum1 += x;
            } else {
                sum2 += x;
            }
        }

        // Calculate the difference in sums
        const difference = Math.abs(sum1 - sum2);

        // Update the result if the current difference is smaller than the minimum difference
        if (difference < minDifference) {
            minDifference = difference;
            for (let i = 0, n = 0; i < totalNumbers; i++) {
                if (bitmask & (1 << i)) {
                    result[n++] = numbers[i];
                }
            }
        }
    }

    return [result, numbers.filter(x => !result.includes(x))];
}

// Function to count the number of set bits in a number
function countSetBits(num) {
    let count = 0;
    while (num) {
        count += num & 1;
        num >>= 1;
    }
    return count;
}

[proven lantern]

that code is so confusing

the countSetBits and bitmask < (1 << totalNumbers); part mostly

[quartz kindle]

it took me a while to understand it as well

basically

[proven lantern]

if (bitmask & (1 << i)) {

[quartz kindle]

its using bits to iterate over combinations

ie

0b00001111 = check items 4 5 6 7 from the array

[proven lantern]

oh, that's a good way to iterate through all the combinations

[quartz kindle]

ye

[proven lantern]

very tricky

[quartz kindle]

then it increments the number

and checks if the bits do have the right number of items set

if not, skip that number

[proven lantern]

0001 -> 0010

and it doesn't need to store all the combinations, it just keeps the lowest until it's tried everything

[quartz kindle]

ye

actually

there is one more optimization i can add

[proven lantern]

exit out if it's 0 difference?

[quartz kindle]

an early termination if the number is within 1 of perfect average

ye

[proven lantern]

not a bad optimization

[quartz kindle]

let me test

[proven lantern]

countSetBits(bitmask) !== halfTotal so this is making sure half the bits are 0 and half are 1 right?

[quartz kindle]

yup

[quartz kindle]

without

with

lmao

[proven lantern]

is that with random numbers?

[quartz kindle]

ye

[proven lantern]

maybe it got lucky

[quartz kindle]

im having some weird results

let me double check

[quartz kindle]

i found a bug in my previous optimization lel

[proven lantern]

oh same numbers in both lists error right?

numbers.filter(x => !result.includes(x))

[quartz kindle]

yup

new code (even better)

function splitNumbersEvenlyOptimized3(numbers) {
    const totalNumbers = numbers.length;
    const halfTotal = totalNumbers / 2;

    let minDifference = Infinity;
    let result = 0;

    // Iterate over all possible bitmasks for the first list
    for (let bitmask = 0; bitmask < (1 << totalNumbers); bitmask++) {
        if (countSetBits(bitmask) !== halfTotal) continue; // Skip if the number of set bits is not halfTotal

        let sum1 = 0;
        let sum2 = 0;

        // Distribute numbers based on the bitmask
        for (let i = 0; i < totalNumbers; i++) {
            const x = numbers[i];
            if (bitmask & (1 << i)) {
                sum1 += x;
            } else {
                sum2 += x;
            }
        }

        // Calculate the difference in sums
        const difference = Math.abs(sum1 - sum2);

        // Update the result if the current difference is smaller than the minimum difference
        if (difference < minDifference) {
            minDifference = difference;
            result = bitmask;
            if(difference < 2) {
                break;
            }
        }
    }

    const r1 = [];
    const r2 = [];
    for (let i = 0; i < totalNumbers; i++) {
        const x = numbers[i];
        if (result & (1 << i)) {
            r1.push(x);
        } else {
            r2.push(x);
        }
    }

    return [r1, r2];
}

// Function to count the number of set bits in a number
function countSetBits(num) {
    let count = 0;
    while (num) {
        count += num & 1;
        num >>= 1;
    }
    return count;
}

[proven lantern]

that's super fast

[quartz kindle]

im running it lots of times in a random generated array and have yet to find a "non lucky" one

which means

this problem actually has multiple solutions, not only one

there are multiple arangements of numbers that have the same result

let me prove this

[proven lantern]

    break;
  }

lol

[quartz kindle]

or not

im confused now

[proven lantern]

i did 100 iterations and it always matched

[quartz kindle]

there we go

check this out

2140 combinations where the difference between sums is less than 2

[proven lantern]

i wonder how many are 0

[sharp geyser]

What the hell are you guys doing

[quartz kindle]

some cant have 0

if all mmrs combined are uneven, it cant be 0

so basically

we managed to improve performance by over 2000x

lmao

since you only need 1 combination, not all of them

[proven lantern]

that should be worth it

[quartz kindle]

problem solved xDDDD

[proven lantern]

i want to see if i can find a combo that breaks it

i haven't found one yet

[quartz kindle]

run a test case with thousands of randomized inputs

[quartz kindle]

a match making system

from an array of mmrs, split them into two teams as evenly as possible

[sharp geyser]

Is this for a discord bot

[quartz kindle]

i ran it again, this one has over 3k possibilities

well

the bulk of them is literally the same numbers

just in different orders and/or groups

[sharp geyser]

If this is all for a discord bot then wow

Didn’t think people would take it this seriously to implement mmr

[quartz kindle]

ask ben about it lmao

[proven lantern]

mmr is serious business

[sharp geyser]

Meh

Debatable

If it’s hidden mmr then it’s bogus and shouldn’t be implemented

[quartz kindle]

if it were me i would just go with a naive function

[sharp geyser]

Nothing I hate more than games implementing hidden mmr

Also mmr isn’t really needed if a rank system is in place, just match people based off rank

[proven lantern]

these probably have solutions with 0 elo diff too, but is it really worth it to try every combo just to balance by 2 more points

[proven lantern]

mmr systems protect noobs from us

[quartz kindle]

it checks for diff < 2

so either 1 or 0

1 if total is uneven, 0 if total is even

even total cannot have a diff of 1

liekwise uneven cannot have a diff of 0

[proven lantern]

oh yeah, so should it check for difference === 2 instead of difference < 2?

[sharp geyser]

Truth be told who cares about new players

[proven lantern]

oh wait

that's 1

[quartz kindle]

you always need to check for both, even and uneven

[sharp geyser]

It’s not a competitive game if you hand hold people

You won’t be able to stop smurfing by any means

So mmr is a toxic system

[proven lantern]

a high elo chess player vs a noob isn't going to be a fun game for either

[sharp geyser]

It harms new players than it does help

[sharp geyser]

Okay that’s not what an mmr system is for

You’d match people based off rank

[proven lantern]

that makes the matches more interesting

[sharp geyser]

mmr is a system to "stop" smurfs from ruining the game for new players by ranking them up to get them back into their appropriate elo. Usually by measuring based off how good they do in a match

Which is a toxic system

Because what if a new player just happens to get some lucky wins and now they are facing people in the top 500 leaderboard (exaggerated example but point still stands)

Doing a rank based system is better off than mmr which is controlled solely based off match performance

[proven lantern]

mmr can be implenented in a bunch of different ways

[sharp geyser]

Fair enough just don’t implement it poorly then

Cause it can and will create a toxic game play

Just look at riot games

[quartz kindle]

mmr is just elo, nothing more nothing less

[sharp geyser]

Their mmr is hidden and it creates a toxic environment for new players who happen to just be good enough at the game to excel in their rank but not good enough at higher ranks

[quartz kindle]

the whole rank system was placed on top of it to make it more appealing

but under the hood its the same elo as it always was

[sharp geyser]

Yet they are forced into gold lobby’s while still being at silver skill level

[quartz kindle]

they just tweak how hard it scales every now and then

[sharp geyser]

I think hidden mmr is the dumbest thing (a lot of games hide their mmr)

I also think the rank system in a lot of games are shit too

[proven lantern]

sometimes showing a leaderboard encourages noobs to cheat

and devs dont want to deal with it

[sharp geyser]

Okay but I assume this is a discord bot

You can’t really cheat

[quartz kindle]

you can win trade

:^)

[proven lantern]

it's up to the discord admins to stop cheaters

[sharp geyser]

Not if you require them to visit a page before playing and tying their ip to their account /s

[quartz kindle]

that wont stop you from win trading

[sharp geyser]

It’ll stop you from having multiple accounts

[quartz kindle]

vpns, multiple accounts, friends, paypal

[proven lantern]

the admins record matches, but they could still be tricked into fake recording matches

social engineering

[sharp geyser]

Time to bribe the admins

Either way good luck

Hopefully your ranking system won’t be as bad as others

[proven lantern]

it's the chess ranking system

[wheat mesa]

chess ranking is actually a pretty decent system

Most matches are pretty evenly matched when you have two players about 1000 elo playing each other

At low elos it's a little more unbalanced because it's often just chaos but still

[proven lantern]

why does this fail once the list is 32 numbers long? shouldn't it fail at 34?

this
#development message

[proven lantern]

i switched to bigint. i switched back

[radiant kraken]

JavaScript tends to act weird with bitshifting large numbers

[frosty gale]

bigints are cursed

you should only use if absolutely necessary for example cryptography since you need massive prime numbers

64 bit ints should suffice for 99% of purposes anyways

[quartz kindle]

js cant do bitwise on normal numbers bigger than 31 bits

since it uses signed ints, at 32 bit it becomes negative numbers
however, there is a way to do bitwise with math, this way you can trick js into doing bitwise operations correctly until its safe integer limit of 53 bits

[raw lagoon]

How much do you earn per month for having a bot with premium functions (cost 10 euros)?

[quartz kindle]

depends on how big your bot is, how popular, etc

[raw lagoon]

For example the MEE6 bot?

[quartz kindle]

you can estimate that around 1 every 1000-2000 users will pay for premium

if you have a million users, thats 500-1000 paying users

[frosty gale]

at this rate mee6 wouldn't be a fair comparison since it's basically a business at this point and discord bots are one aspect of it

[raw lagoon]

So if 500 users are paying 10 euros per month, would they be earning 5000 euros?

[quartz kindle]

pretty much

before taxes that is

mee6 is probably bigger than that tho

[unreal lotus]

In what ways do you keep your bots online/running?

[quartz kindle]

we pay for a VPS

[unreal lotus]

how mutch if i can ask that?

[deft wolf]

I pay 5 euros for more than my bot needs, so you can easily find a nice VPS for 3 euros

[unreal lotus]

lifetime?

[deft wolf]

No, monthly

[quartz kindle]

like 4.50 eur

there are some providers that offer free tiers, for example google, amazon, and oracle

[unreal lotus]

can it run then how mutch bots you want?

[quartz kindle]

google has a free forever 1gb ram vps

but they charge you for network usage if you use more than 1gb or internet per month

amazon gives you free trial for 12 months

[deft wolf]

Yes, I personally host one public and 4 private bots

[quartz kindle]

it depends on how big your bots are, and how resource intensive they are

[deft wolf]

And I still have over 8GB of free ram

[unreal lotus]

and you can run unlimetid if you want?

[unreal lotus]

ow so not limetid

[quartz kindle]

for example

i've seen some large bots, like 150k guilds

that use 40-50gb of ram

[unreal lotus]

what for bots are that?

[quartz kindle]

so it depends on how efficient your bot is

[unreal lotus]

do you guys now what the largest bot is?

[quartz kindle]

it used to be rhythm, but idk now

here

https://gist.github.com/advaith1/451dcbca2d7c3503d4f48d63eb918cb0

[unreal lotus]

thx

[unreal lotus]

do you have a link?

i cant find it

this:?

(i know its in dutch because i'm from belgium)

[quartz kindle]

yes

[unreal lotus]

what is this?

[quartz kindle]

when you create an instance, it has to be of type e2-micro, and it has to be in one of those 3 regions

otherwise its not free

[unreal lotus]

so is it free in belgium ore not?

[quartz kindle]

the regions are the place where the server is

not where you are from

[unreal lotus]

ow

euh...

[quartz kindle]

for example

[unreal lotus]

Oh k thx man for youre help

[lyric mountain]

I think it's worth noting that you'll have to get used to command line interface

there's no panel or one-click setup or anything, all done from terminal

[quartz kindle]

watch them install windows server with gui and remote desktop

[lyric mountain]

lul

[wheat mesa]

Just install libxz, it’s basically Remote Desktop anyways ;^)

[pale vessel]

except that only one guy could access ur desktop and it's not u

[past field]

sorry i meant to upload this last night and fell asleep.. lol

[inner heart]

anyone know how to fix this

@unkempt ocean

@rare mist

[spark flint]

read the error ☠️

no need to ping random people

[inner heart]

ok

[unkempt ocean]

Not all of us are developers here, if you need help with Top.gg support you can ping us but in here you need to ask your question and be patient about it

[inner heart]

sorry

sorry

[wheat mesa]

Eh someone made a patcher to modify the exploit to put your own pubkey instead of the attacker’s

You can always use that 😉

[pale vessel]

wait really 💀

[wheat mesa]

Yeah

It was made for the purpose of researching the exploit

Not actually to infect computers

[quartz kindle]

too soon lmao

[quartz kindle]

you're trying to use discord.js but its not installed

you need to install it

[grim aspen]

do npm install discord.js

in console

[frosty gale]

are there any more discord libraries for js now

or is it still the same discord.js and eris landscape

[radiant kraken]

bot devs are making their own discord libraries now

[quartz kindle]

experienced devs maybe

but normal devs are pretty much still hogging discord.js

havent seen any mention of eris or others in a long time

[radiant kraken]

go libless

[quartz kindle]

is it still libless if you make your own code into a lib?

:^)

[harsh nova]

If I was going libless I'd probably switch to a new language

[radiant kraken]

like Rus-

[quartz kindle]

i havent touched any discord code ever since i moved to tiny-discord + webhook slash commands only

it feels like you finally get peace of mind

no need to worry about scaling or updates

new discord features can be added directly to the code, without needing any lib update

bot will pretty much never exceed 100-150mb ram usage, no matter how big it gets

[radiant kraken]

and then there's dpp

[quartz kindle]

sure, but thats overkill at this point
