development

[queen needle]

I would have thought to use local storage

[solemn latch]

You have to get that right.
The worst feeling is watching peacock and it completely losing track

[sharp geyser]

local storage is too limiting

Imagine they were watching 100 videos, and they never finished any of em

Kind of exaggeration

but its better to store this somewhere else more mangable

[solemn latch]

That and not keeping it between browsers/devices

[queen needle]

I get what you're saying

[sharp geyser]

^^^

[queen needle]

Yeah that's fair

[sharp geyser]

I plan on making a mobile app in the far future

[queen needle]

I still think websockets would be nice for that, just making it easier to save it

[sharp geyser]

not to mention people swap browsers like opera gives out cars sometimes

or they clear cache inadvertanly clearing local storage on websites too

[queen needle]

how would you store it? Like key value of Id to timestamp?

[sharp geyser]

Not sure yet

my first thought is index it based on video ID + user ID

then have a timestamp of where they were in the video and just send em there

[queen needle]

That makes sense

[sharp geyser]

I could hash the video ID and user ID together and store that so Im not querying based off two columns if I wanted

just to make it a bit faster

idk I will figure it out when I get to it

I first need this media player working

💀

[queen needle]

what isn't working?

[sharp geyser]

nothing yet

because I havent started

💀

I was about to eat dinner

[eternal osprey]

This reminded me of the reason why tcp cookies were created

[sharp geyser]

hm?

[eternal osprey]

A client could send so much tcp syn segments to a server, which would then save ongoing and not acknowledged tcp connections in its buffer. It was a way to dos a server

Hence they came with tcp cookies, which is used to hash the details in a isn that the server creates and stores on the client instead. But as it’s just one singular isn, it’s very limited. So nowayadas browsers use the normal buffers but if they reach the max, they fall back to tcp cookies

Don’t mind my yap sometimes I just let my mind speak to my imaginary friends

It’s lonely sometimes

[sharp geyser]

All good man its very interesting stuff

right so how the fuck do I scale a video element

cause its not co-operating with me

😭

[neon leaf]

does anyone know a good 4u case thats not 10 trillion usd and max 35cm in depth

[sharp geyser]

4u case?

[neon leaf]

yes

[sharp geyser]

ah

server rack

Talk to sky about that one

Bro knows everything there is about servers

[neon leaf]

there are many skys sir

[sharp geyser]

@pine willow

He's likely not alive rn idk what time it is in berlin

[neon leaf]

same as me

12am lol

[sharp geyser]

Oh yea bro might be asleep

[neon leaf]

nah

[sharp geyser]

but he's the best one to talk to

He knows more about servers than I'd wager anyone else in this chat

[neon leaf]

ok I will order everything else for now then

[sharp geyser]

@solemn latch How does this look

I cannot for the life of me figure out how to size the video element, and make the video itself look normal

😔

oh wait

object-contain seems to have fixed it

[frosty gale]

[sharp geyser]

I just hope it doesn't look this weird with actual content streamed from my cdn

because all that empty space in the player looks terrible

YOOOO

I GOT HLS STREAMS WORKING :D

[neon flicker]

How to detect once a GuildMember updates their guild nickname?

[sharp geyser]

member update events

https://discord.js.org/docs/packages/discord.js/14.15.3/Client:Class#guildMemberUpdate

[neon flicker]

Thanks

[surreal sage]

i tried to watch nl vs tr via hls playlist but it just didnt want to

online hls player did work

[sharp geyser]

I made my own using hls.js

<script lang="ts">
    import {page} from '$app/stores'
    import Hls from 'hls.js'
    import { onMount } from 'svelte';

    onMount(() => {
        const video = document.getElementById('video') as HTMLMediaElement;
        const source = $page.data.video.url

        if(Hls.isSupported()) {
            const hls = new Hls();
            hls.loadSource(source);
            hls.attachMedia(video);
        } else if (video.canPlayType('application/vnd.apple.mpegurl')) {
            video.src = source
        }
    })

</script>

<div>
    <h1>hello</h1>
    <div class="w-full">
        <video id="video" class="w-full h-[30rem] object-contain" controls></video>
    </div>
</div>

simple as this

[frosty gale]

inventing something thats already existed under another name is such an apple thing

i think thats basically what hls is

[quartz kindle]

i have no idea what im doing (send help)

[frosty gale]

and i dont wanna know what youre doing

[neon flicker]

Is there a bot that allows us to copy emoji ID's?

I can't use the backslash method as I don't have nitro

[sharp geyser]

I mean without the emote you wont be able to

You would have to be able to send the emote

or you can copy the emoji url

https://cdn.discordapp.com/emojis/947283601186254858.webp?size=240&quality=lossless

https://cdn.discordapp.com/emojis/947283601186254858.webp?size=240&quality=lossless

[neon flicker]

Aw nope, I'm trying to add emojis into my bot

[sharp geyser]

What im saying is

you can download the emote to your server via that link

Download the emote, save it to your server

[neon flicker]

It still doesn't allow me to copy the ID of it

[sharp geyser]

Well

You would have to know the emote you want

and have to get the link

[neon flicker]

Aw I found a bot which provides us the ID's of the emojis

[frosty gale]

bro couldve done it himself

[proven lantern]

i almost used all my github action minutes getting a Hello World zig lambda deployed

[neon flicker]

Nope, \:emoji: won't work as I don't have nitro and the emoji is animated

[solemn latch]

can you not just right click and copy the id?

[neon flicker]

God so there's an option for it 🤦‍♀️

[surreal sage]

the debugging is real

[neon flicker]

await DB.set(`${interaction.guild.id}.blacklist.${userId.toString()}`,dataStructure)

RangeError: Invalid string length
It's quick.db if it's an important information

[surreal sage]

ur dataStructure is too long when stringified likely

[neon flicker]

What exactly is the limit tho?

Apparently, I don't think it's way too long. Hold on

{
  reason: 'No reason was provided.',
  date: 1720309497817,
  moderatorId: '735807653594398742'
}

This is dataStructure

[surreal sage]

-((-1) << 30 + 1) = 2147483648 = 2048M

https://github.com/nodejs/node/issues/35973#issuecomment-722253319

im not sure

its a weird error and i dont rlly know how to fix it either

[neon flicker]

Well, it works to execute the following:

await DB.set(`blacklist.${userId.toString()}`,dataStructure)

But not the following:

await DB.set(`${interaction.guild.id}.blacklist.${userId.toString()}`,dataStructure)

[surreal sage]

dude

E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/g/glibc/libc-dev-bin_2.35-0ubuntu3.4_amd64.deb  404  Not Found ```

what is this

cant even install c

forgot to update mb

[quartz kindle]

quick.db uses sqlite right?

can you check your sqlite file and open it with an sqlite viewer? i have an idea about what the issue is (tldr quick.db is bad)

[tawny lava]

this is very vue

(ik it's not)

[sharp geyser]

lol

I got a working media player tho

albiet a basic one

but its cool

Now that I know i have the capabilities to do it myself I am

Time to work on the backend some more :D

[sharp geyser]

@lyric mountain I know this isn't postgres related but I have a db question

How should I keep track of creators, videos and subscribers?

My original idea was to make a table called creators, and videos, then have a relation between users -> creators -> videos

then have subscribers table be a relation of users -> subscribers -> creators

[frosty gale]

ez

subscribers table which contains user id/reference, creator reference/id and whatever else you want

then when fetching creator you can join that table to see if the user is subscribed to them

and do a count to see how many subscribers a creator has

all of this should of course be cached as much as possible especially the subscriber counts

[sharp geyser]

I am using surrealdb

So it has handy features to get this data performantly

Its just surrealdb is similar to your average sql database, but it varies a bit

It has support for your traditional linking of tables, but also graph relations

[frosty gale]

although you can also do a postgres routine to update a counter in a database so you can instantly fetch the subscribers a channel has without counting or caching much

[sharp geyser]

So I can have

1. User table
2. Creator Table with a link to User table
3. Subscribers table with a graph relation as User and Creator (user (node) -> subscribers (edge) -> creator (node))

[sharp geyser]

If I was using pg sure

[sharp geyser]

@gloomy marsh ?

Why ghost ping

[gloomy marsh]

didnt mean to reply to you

[sharp geyser]

right well dont just delete it, just say so

ghost pinging is not nice

[gloomy marsh]

this guy 💀

[gloomy marsh]

whats your question here exactly

[sharp geyser]

There was no question

It was a statement

[gloomy marsh]

ah ok

[warm carbon]

does a bot need manage threads to assign the thread perms on a role

[sharp geyser]

yes

[gloomy marsh]

yes

[warm carbon]

ah that explains it

[sharp geyser]

A bot needs the permission it wants to grant/revoke others

[warm carbon]

ah ok

i was wondering why my bot needed that but i figured out a bit later, just wanted to confirm

[sharp geyser]

👍

[warm carbon]

wat

[sharp geyser]

I was just saying ok

[wintry river]

Sometimes i'm getting this error in my response from top.gg api back when trying to post changes

[sharp geyser]

502 is a cloudflare error

[deft wolf]

Classic Bad Gateway error

[sharp geyser]

Just ignore 502 errors

[wintry river]

oh okay

[sharp geyser]

Nothing else you can do

[wintry river]

so it's a "deny" error, should i retry to post?

[sharp geyser]

no

its not a deny error

502 means that the gateway is closed/bad e.g you cannot give or receive any connections from top.gg

[wintry river]

ok

ty

[sharp geyser]

All you can do is ignore 502 errors and hope it gets resolved

[wintry river]

any other error statuscodes i should "ignore"

[wintry river]

it was resolved on the next restart couple mins later

[sharp geyser]

Anything other than a 4xx or a 500

typically 500's aren't errors you can fix either, but if you can gracefully handle them by just logging them. It might be useful information to report

[eternal osprey]

hey, i have an emojiReactAdd event.
THat even is partial so it does not work on older messages.
If my client reconnects (which it does after a long time), does it still work on the messages from before the reconnect, but after the bot was online for the first time?

[gloomy marsh]

No

unless those messages are fetched and cached again.

[eternal osprey]

Is there a way to stop reconnects?

[gloomy marsh]

yes

[eternal osprey]

Owhh how

[gloomy marsh]

python?

[eternal osprey]

Js

[gloomy marsh]

Setting ws.reconnect to false

well i mean

you can stop it from auto reconnecting but

sorry i got confused with ur question

you mean like stop it from doing the reconnecting shit completely?

[pine willow]

Wha

[eternal osprey]

Yeah

[pine willow]

ping ponged?

[gloomy marsh]

nah there isnt a way

issues on discord's end

itll happen

[eternal osprey]

So I must fetch the messages first and then it would work?

[gloomy marsh]

yes

[eternal osprey]

I see, using that we can also allow older messages to be cached ain’t it?

[gloomy marsh]

yeah if you use the reaction.fetch

[neon flicker]

Yep, and specifically better-sqlite3

Well, apparently

DB.set(`${interaction.guild.id}.logschannel`, channel.id)

Is fine, but it doesn't work when there's a third dot such as

DB.set(`${interaction.guild.id}.blacklists.${interaction.user.id}`,dataStructure)

Ah it's not related to the third dot, it's due to the length of the entry string

I found it though

I'm not sure why this occurs

Yes, now I'm pretty much sure that it's due to the third dot

[sharp geyser]

💀

I am too tired to try and help you diagnose that

I am barely pulling through my own project

[neon flicker]

Uh what do you mean?

Sorry if I'm asking way too many questions but I'm back to JS development after long so I'm not sure what I'm doing wrong

[sharp geyser]

No no no

I was simply saying I am too tired its 8am almost

I want to help, but any information I give you might be wrong due to my sleep depriveness

[sharp geyser]

dataStructure is a bunch of null values

log dataStructure

[neon flicker]

Oh sorry lol, I've read it as "I'm too tired of" instead of "tired to"

[neon flicker]

Nope, I tried printing it out and it's

{
  reason: 'No reason was provided.',
  date: 1720309497817,
  moderatorId: '735807653594398742'
}

[sharp geyser]

Are you 100% certain this is happening at that specific line

[neon flicker]

Yes, the error code prints out that line

[sharp geyser]

I have no idea how set works, but my only guess is, it can't identify that location

Probably better to wait till someone who knows better sqlite 3 better to help though

[neon flicker]

Yep

[gloomy marsh]

key length issue?

[neon flicker]

RangeError: Invalid string length

[gloomy marsh]

yes

[neon flicker]

Is there a way to solve it?

[gloomy marsh]

break the data into smaller parts or shorten the key

[neon flicker]

The data seems to be really small already

[gloomy marsh]

then its the key length

[neon flicker]

Well, there doesn't seem to be any way to shorten it

I changed blacklist to b, it still does not work

[gloomy marsh]

have u tried storing the data as a json string before saving it

your making my brain work too hard at 8 am

i also only read half of the things you sent

😭

[gloomy marsh]

@neon flicker lmk

[neon flicker]

How would I do that tho?

JSON.stringify?

[gloomy marsh]

yes

then youd need to retrieve and parse the data

JSON.parse

[neon flicker]

I'll let you know soonly

[quartz kindle]

the problem is

quick.db works the same way as json files

it only has 1 table to contain everything

and it only handles the first key

[neon flicker]

Then it's useless for me for now

[quartz kindle]

which means whenever you set or get anything at all, only the first key is an actual table row, the rest of it is inside a json file embedded in the row

[neon flicker]

Or either I will have to store them as arrays

[quartz kindle]

for example

if your key is blacklists.guildid.etc

everytime you do anything to that, the db has to fetch blacklists, json parse the entire blacklists, set the data, then stringify the entire blacklists again, and set it back in the row

so you can see how that can quickly ramp up to gigantic json files

[gloomy marsh]

ah

[neon flicker]

What am I really supposed to do in this case?

[quartz kindle]

if you want to keep using quick.db, you need to change the structure of your db in order to create smaller rows

[surreal sage]

what thefuck

[neon flicker]

Is there a useful alternative for quick.db?

[quartz kindle]

you can always use better-sqlite3 directly

you have more control over it that way

but essentially, you need to keep in mind that only the first key matters, everything else will be treated as the same file

so you need to keep the first key small

[neon flicker]

Like firstkey.secondkey.thirdkey and the first key is firstkey in this case, right?

[quartz kindle]

yes

also

[sharp geyser]

Oh it’s quick db

That’s still a fucking thing?

[quartz kindle]

if you remove the dot, it will force quickdb to create a separate row for it, and not put everything inside the existing value of the virst key

[neon flicker]

Yes, somehow

[quartz kindle]

for example

[sharp geyser]

quickdb uses dot prop to traverse the objects no?

[quartz kindle]

if your key is a.b.c, quick db will save it as a => { b: { c: ... } }

if your key is a-b-c, quickdb will save it as a-b-c => { ... }

so you can fix your issue by not using dots

the only disatvantage is you lose the ability to "fetch all children", like you cant use a to get everything inside it anymore

[sharp geyser]

Tim why don’t you make a more performant json database

[quartz kindle]

lmao

[neon flicker]

Yes, I wouldn't be able to delete them all

Or maybe a.b-c would be an option as well

[sharp geyser]

Another option : mongodb

[quartz kindle]

yes, as long as you dont let the actual json value get too big, you should be fine

[neon flicker]

I never understood mongodb, tho the last time I used it was like 2 years ago

[quartz kindle]

mongodb bad

:^)

[sharp geyser]

Good enough for their use case

Unless you want them using Postgres

💀

[neon flicker]

I think I will give it uh, another try

[quartz kindle]

quickdb is fine

as long as you respect how it works internally

[sharp geyser]

Tim

[quartz kindle]

which is not very obvious

[sharp geyser]

I never thought I’d see the day where you promote bad practices/j

[quartz kindle]

the opposite is better btw

a-b.c

otherwise a will still contain everything

[sharp geyser]

But then doesn’t a-b contain everything either way

[neon flicker]

But then it would look like guildid-logchannel => {c: {}}, and I can't really delete all the guildid-... values

[sharp geyser]

You can

[neon flicker]

*At once

[quartz kindle]

use separate tables

[sharp geyser]

Ima be real json dbs suck but if it’s small scale it’s fine

[quartz kindle]

quickdb has the ability to create separate tables

     const db = new QuickDB();
     await db.init();
     const table = await db.table("test");
     await table.set("test", "Hello World");
     console.log(await table.get("test"));

[neon flicker]

Seperate tables for each guild?

[sharp geyser]

Wait doesn’t quick.db use SQLite not json what was the one that used json

[quartz kindle]

sqlite itself is table based, if you dont use tables then you are not taking full advantage of sqlite

[quartz kindle]

enmap?

[sharp geyser]

Enmap I think

[quartz kindle]

separate tables for each type of thing, for example a table for blacklists, a table of users, a table for guilds, etc

then on each table, the id is the main key

guildid on guilds table, userid on blacklists table, etc

the main key should be as unique as possible, so you have more keys and less stuff inside each key

[sharp geyser]

Is enmap still relevant btw

[quartz kindle]

so always use discord ids as the main key for each relevant table

[quartz kindle]

i still see people using it every now and then

and having problems of course :^)

[sharp geyser]

Well yes

It’s json

And I don’t think it’s maintained anymore

[surreal sage]

please my sanity is deteriorating

[quartz kindle]

it is maintainet still

[sharp geyser]

wtf

[neon flicker]

So it would be something like:

const DB = new QuickDB()
const Guilds = await DB.table("guildsettings")
const Logchannel = Guilds.get(`guildid.logchannel`)

[sharp geyser]

What are they updating? Variable names?

Like there’s not much to a json db

[quartz kindle]

yeah that should be fine

[neon flicker]

Thank you

[sharp geyser]

Does JS have hash maps

I don’t remember

[quartz kindle]

Map basically is one

objects kinda are one as well

[sharp geyser]

Oh really?

[quartz kindle]

and arrays too

lmao

[surreal sage]

[[],[],[]]

[sharp geyser]

Tim

If an object is a hashmap

[pearl trail]

Cook

aww late

[sharp geyser]

EVERYTHING in js is a hashmap

[quartz kindle]

yes

[sharp geyser]

That’s cursed

1 a number? Nah buckaroo it’s just a hash map

[quartz kindle]

well, of course there are countless optimizations

objects have "shapes" internally

[sharp geyser]

And yet js still sucks at heavy workloads

[quartz kindle]

depends on the work load

[sharp geyser]

If it can’t run my ai model trained on 5PB of data then it’s slow

[quartz kindle]

ye good luck running that on any language

[sharp geyser]

[surreal sage]

5 pb of mem ✅

who needs ssds anymore

[sharp geyser]

I’ll just use Tim’s dna

[surreal sage]

just keep ur server on

hardcore mode

[quartz kindle]

use youtube videos as storage, store data in pixels in frames in videos

[sharp geyser]

Not only can I store a gazziliom gigabytes of data

But it’ll be naturally optimized for quick access

[sharp geyser]

Pfft videos? I use movies

[neon flicker]

Thank you all, the new data structure pretty much worked

[sharp geyser]

Nice

[surreal sage]

can someone please help me with gh actions

[sharp geyser]

Google can

[surreal sage]

https://github.com/ari-party/mtc-artillery/actions/runs/9827150148/job/27129560830

[quartz kindle]

it will be much mmuch faster as well

no more parse/stringify gigantic json files

[sharp geyser]

Hey Tim I have a question

What turned you into the optimization god

And the pro benchmarker

[quartz kindle]

not wanting to pay for more hardware

[sharp geyser]

At this point I’m convinced you wrote the js programming language

[sharp geyser]

That’s so relatable

Except I push my hardware to the max

MacBook turns into a griddle

[surreal sage]

warm up some burgers

[sharp geyser]

Thought about it

[neon flicker]

LOL

[frosty gale]

find some random php website/instance with an open upload endpoint and use it as file storage

youd be surprised at how many there are that have unrestricted file uploads which you can view at any time

[lament rock]

I get too many hits to phpmyadmin endpoints on my bot's website

[surreal sage]

DUDEEEEEE

WHAT IS THIS ERROR

[pearl trail]

it's panicked

you must make it calm

[neon flicker]

Is message.mentions.roles.first() still a valid function to get the first role mention of a message (djs)?

[surreal sage]

https://tryitands.ee ... if it works it works :3

[deft wolf]

This function works on every possible collection in discord.js afaik

[neon flicker]

Thanks

they took my vsc

[earnest phoenix]

hi quick question, what are some good d.py forks that I can use

[solemn latch]

👀 is there a reason you want to use a fork?

[earnest phoenix]

Well honestly, I've been using nextcord since d.py was dead back in the day and there are a little things of nextcord that I can't adapt to which is why I would like to move to a different fork

[earnest phoenix]

Thanks, I'll check all of those

Is pycord good? I've heard people saying their code is bad or something I didn't read it till the end but it was on reddit

[quartz kindle]

no idea, i dont use python

:^)

[earnest phoenix]

ah

no worries, thanks anyway!

[frosty gale]

choose one thats recently maintained and figure out if you like it

although most of them will be relatively similar with changes to conventions

[earnest phoenix]

alrighty

thank you

[eternal osprey]

does anypne know how the fuck they get 8n?

where does it come from

[sharp geyser]

Magic numbers

Once I start seeing infinity in the fucking formula

I stop paying attention

💀

[scenic kelp]

the infinity is not the issue it's a series

the 8n is

[eternal osprey]

yeah

how do they know that the upperbound of the sum must be 8n?

[sharp geyser]

chatgpt time /j

[eternal osprey]

chatgpt says its 3n instead of 8n

but these are the test answers lol

[narrow valve]

8n represents the number of terms used to get the intergral over the interval

[eternal osprey]

that ain't my question tho

how

[slender wagon]

I've been using psql and prisma for my database, with discordeno. Now for some reason the size of the bot just keeps on growing until it crashes the vps. And for some reason the db is doing some visible caching, do u guys know where i can disable this or what could be the reason it's doing this. (Notice the allocation it does after each query)

[lyric mountain]

ok so, databases will always try to use as much memory as allowed for caching, this is intentional as it improves speed

but as a plumber would say: you got a leak there sir

let the bot run for a while, when the memory usage gets high enough, take a heap dump

this will allow us to know what's being accumulated in the heap

[sharp geyser]

classic memory leak with prisma

[lyric mountain]

also, I'm unsure if this is also the case for other lands/frameworks, but you should always free connections after using them, else it'll stay open until you either OOM or the database closes it

[sharp geyser]

prisma requires you to close connections after you are done with them

else like you said, they will stay open

$prisma.disconnect or smth

[slender wagon]

some guy on another server pointed out bun

cuz really the bot is a bit basic

[sharp geyser]

swapping to a different runtime

why not just use node at that point

💀

[slender wagon]

i could

but bun has been a time saver

but for some reason now it started pointing the issues (if it is bun)

[lyric mountain]

do the heap dump, then we'll have something to work with

[slender wagon]

what should i use

[lyric mountain]

all runtimes have some sort of heap dump tool

[slender wagon]

bun does but for some reason only safari can read it or smthn

💀

it provides it on a json

[sharp geyser]

[lyric mountain]

all frameworks will ALSO have some sort of tool to analyze the dump

you're not supposed to read it as-is

[slender wagon]

https://bun.sh/docs/project/benchmarking

it's either safari or WebKit GTK (which i am totally not familiar with)

[lyric mountain]

safari is a browser no?

[slender wagon]

yes

and i am on linux

[lyric mountain]

well, use it then

[slender wagon]

i can't use it here

but

i will try to get it on my windows

[digital swan]

i believe prisma handles connections for you
i've never had to use prisma.$disconnect before

[sharp geyser]

Unless they changed their ways you have to do it yourself

[sharp geyser]

Interesting

I guess they changed

You used to have to explicitly call them

[slender wagon]

eitherway it's a discordbot and it kinda uses it all the time so that wouldn't be an issue

[digital swan]

yeah i agree i doubt prisma is causing problems

from my experience bun uses more memory than node

could you try running it with node for some time or are you using bun features

[quartz kindle]

if its a discord bot, then most likely its the discord cache using all the memory lol

[frosty gale]

its also possible the gc just doesnt feel like running

it only runs when node starts running out or when its convenient bc it has to freeze everything

so old object pile up

[sharp geyser]

They are using bun tho

todays craziness: https://github.com/brainboxdotcc/ssod/blob/main/include/ssod/js.h

an async js interpreter in C++, using coroutines and a threadpool

[sharp geyser]

why

[green kestrel]

for game events

basically most of the games runtime stuff is js scripts embedded in game locations, effects, spells, achievements etc

but each was blocking and can take multiple milliseconds per script

so too many concurrent players could potentially lag it

basically most of the games content is configured in the db like this @sharp geyser

no need to hard code anything, can all be tweaked on the fly

[sharp geyser]

interesting

[surreal sage]

c#? the sea isn't sharp though

[gloomy marsh]

https://tenor.com/view/boooooo-this-guy-stinks-serious-spongebob-squarepants-gif-11981386

[surreal sage]

i agree

[pearl trail]

damn

[slender wagon]

ok docker

[neon leaf]

Ah right thanks for reminding

My HDD docker cache is 700gb

[sharp geyser]

wtf

why so big

[lament rock]

A reminder to everyone that a lot of the dependencies you install are bloat. The majority of them fan out to be massive dependency trees and very quickly become a bottleneck. There is no better way to combat this than to vertically integrate yourself. If you're a library developer, vet your dependencies and make use of tools your package manager may offer like explaining why a dependency was installed.

Why I mention all of this is because one of my projects had lodash in the dependency tree which is just pollution at best

[frosty gale]

a cool suggestion would be to change the language for it to something that can be compiled

how is it executed? my worry is that the same exact script is evaluated many times instead of being compiled

[neon leaf]

i build images

[frosty gale]

maybe something like c# where you can build a bytecode version of it and have that directly execute the code

[sharp geyser]

its in the browser

it has to be js no?

[lament rock]

You can run asm in the browser. Wasm

[sharp geyser]

i mean sure

[frosty gale]

i thought hes using that to quickly make changes to different achievements/xp gains scripts in his bot

[sharp geyser]

but thats still js

[frosty gale]

yes you can run js on the server

[sharp geyser]

maybe idk

oh wait he did make the browser version int oa bot didnt he

I was still thinking he had it all in the browser

[frosty gale]

i have no idea lol but last time he talked about it he mentioned this script runs in the bot

since its easier to be able to configure scripts on the fly like this instead of re-compiling and restarting the bot every xp/game adjustment

so its either some smaller version of the js engine or its v8 executing that script

v8 is a bit overkill for this so probably something smaller

[lament rock]

wasm can run at near native speeds because of assumptions the engine can make

js by itself is much less safe to do so

[frosty gale]

this isnt wasm though

its just js

[sharp geyser]

what if it wasm was

[lament rock]

nodejs can also import wasm

[green kestrel]

it's interpreted on demand, compiling it doesn't give much performance increase, it's executed server side using a library called duktape that is for embedded systems

the scripts are usually about 15 lines long at most and execute in a couple of milliseconds, taking a handful of kilobytes

it's a different class of interpreter entirely to V8, made for a different task

if it was compiled to run natively sandboxing it would be a ton more risky

you can't run node on this for example

[lament rock]

Are the scripts user definable

[green kestrel]

depends on your definition of user

they're definable by bot staff who aren't c++ devs

[lament rock]

You, the host, are not considered a user in this scenario

[green kestrel]

but bot staff are chosen by me

[lament rock]

or people with admin access you trust to write the scripts

[green kestrel]

it doesn't make sense to compile it

you'd have to load it as a shared object each time

that takes tons of ram, and badly written code can crash the entire bot

as opposed to just logging an error

[lament rock]

interpretation does have its own overhead which can be more costly than additional ram usage from native code and you might not be at the stage where you should consider that anyways. I guess I also don't see you reaching the point where you'd need to consider it

[green kestrel]

the inability to quickly iterate is more expensive than a millisecond to run some code

having to create some C++, to compile it, check it compiles, and then load a shared object possibly across many clusters is a huge problem, compared to just drop-in a 15 line script and boom, a new achievement or potion

[frosty gale]

writes cute script to exploit a duktape vulnerability to break out of sandbox and cause mayhem

[green kestrel]

i dont think theres ever been such a thing

only ever been one CVE in 2022 which would cause a DOS

[past field]

is getting my bot verified a hard process?

[pearl trail]

nope

i heard they make it much easier

[solemn latch]

Its instantly verified now. No manual checking

[pearl trail]

oh damnnn

[radiant kraken]

time to make a spam bot and get it over 75 servers /s

[lament rock]

no server requirements now btw

Why? User installed apps have to be verified somehow

[radiant kraken]

oh nice

[pearl trail]

no way

so basically i can make all my testing bots verified?

[lament rock]

Well… Yeah, but there's literally no benefit to doing this as the only restriction is being able to go past 100 servers. Verified apps also have to apply for privileged intents

[quartz kindle]

what about old bots that were rejected for suspicious growth or wqhatever

[lament rock]

They can verify now afaik

[quartz kindle]

oh rly

[pearl trail]

wh-

[quartz kindle]

i have one like that lmao

[pearl trail]

then what's the point of being verified 💀

[lament rock]

Going past 100 guilds

???

[pearl trail]

well yeah hm

fair

[quartz kindle]

and getting the checkmark

:^)

[lament rock]

Oh I forgot about monetization

But thats a literal scam

Discord takes a large cut

They also require exclusivity when it comes down to users being able to access paid commands

The system only works when they vend through Discord

[radiant kraken]

b-b-but the badge!!! 😔😔

[lament rock]

badge goblins

Active developer comes with the restriction that a user has to use one of your bots' commands every once in a while

I forever lost my badge and will forever be sad

[quartz kindle]

why did you lose it?

[lyric mountain]

HOW did you lose it

didn't even know it was losable

[solemn latch]

Congrats! Become badge free!

[frosty gale]

its very possible

for example if your bot gets unverified they remove it

im not sure if you can lose it now though

discord staff have to do it manually

[lyric mountain]

ah, this makes sense

as now you can get unverified if u dont re-verify every 3 years

I think it's 3 years

[frosty gale]

they probably wont remove it if you get unverified for not verifying again probably

they only usually do it if your bot gets unverified for abuse reasons

[deft wolf]

It seems that if you fail to re-verify your ID, they remove the badge (source: #1237101449398194176 message)

[real wing]

dang lol

[green kestrel]

hmmm that badge is gonna become rarer

I had someone bugging me to sell my discord for £7k in bitcoin, I smell a scam lol

[deft wolf]

If someone offers you money for anything on Discord, it is 99% likely to be a scam

[lyric mountain]

ask for upfront payment of 50% of the agreed value

when they pay, go radio silence

[quartz kindle]

a few years ago i would get a lot of dms wanting to buy my account

i asked one dude for upfront payment, he asked to login to my account first for proof

lmao

[crystal wigeon]

hello

wot

anyway

anyone use rabbitmq?

i got a couple of questions

so i noticed that it creates multiple consumers if i have multiple channel.consume methods. is this expected? i thought you had create new channels to create new consumers. but i noticed the id was same.
Also im trying to like add a consumer once via some api call and then poll messages. how can i achieve this? without like closing the channel. i thought of storing the objects globally but it will probably lead to memory leaks. whats the recommended way to do this

My use case is basically to serve messages from the queue to polling requests and wait for an ack for that message. but i dont want to handle managing the worker poll since it is already taken care by rabbitmq i.e if i have multiple consume methods it will automatically figure out which worker is still processing data etc, it only requeues the message if the worker disconnects and it drops it if the worker acks it.

And the way i ack is via some api call with the same message that was processed. But now how do i reconstruct the channel that sent out the message? since if that channel is closed it will automatically re-queue the message and give the same message to the next poll request.

idk if anything i said made sense

[eternal osprey]

heyhey guys

does this also take categories:

 .addChannelOption((option) =>
      option
        .setName("category")
        .setDescription("The parent category.")
        .setRequired(true)
    )```

[lyric mountain]

categories aren't exactly channels

[eternal osprey]

is there a way to select one?

fuck it i will ask ppl to simply copy the cateogry id

[full wolf]

@eternal osprey no

[neon leaf]

or do a string autocomplete

[eternal osprey]

ah good one

[lyric mountain]

can you ping stuff in dropdown menu?

if so you can simply list the cats using <#cat_id> format

#966028947055841291

it wont become a ping, but it'll at least fill the name through the id

[eternal osprey]

i see, thanks for the help!

@lyric mountain you are good with java right, do you mind looking at my similarity checker in java? For some reason it's fucked

[lyric mountain]

similarity as in string?

[eternal osprey]

image similarity

or are you not that familiar with similiarity checkers in general?

[lyric mountain]

not really, that's usually something better left to AI

[eternal osprey]

Owh alright

well actually

it all comes down to calculations, whether it's with weights or just a eucledian distance.

i think that i know what my issue is.
I am using a similarity measure that's meant for grayscale... do you by any means know any lib or function in java able to grayscale an image?

aka, normalize the pixels to ranges of [0,1]

[lyric mountain]

you'd have to normalize to 0...255

as pixels use int for color channels

but well, it depends on what kind of grayscale u want

and u dont need a lib for that btw

[eternal osprey]

ah really

huh but don't pixels in grascale images either represent a 1 or 0

if i log my grayscale image i get a big matrix of 1's and 0's.

[lyric mountain]

that's a b/w image, not grayscale

[eternal osprey]

while a colored image returns me a matrix of values between 0 and 255

[lyric mountain]

grayscale

[eternal osprey]

ooowhh shit

wait can't i just simply normalize everything by dividing by, say 100?

[lyric mountain]

dividing by 255

to normalize you divide by the max value

int rgb = img.getRGB(x, y);
int r = (rgb >> 16) & 0xFF;
int g = (rgb >> 8) & 0xFF;
int b = rgb & 0xFF;

int avg = (r + g + b) / 3;

img.setRGB(x, y, (avg << 16) | (avg << 8) | avg);

this would be average grayscale

but it wouldn't match visible grayscale, for that you'd use luma formula

[eternal osprey]

owhh damn i see

i totally forgot i am currently using the sum of squared errors on the pixels but that's so stupid

would only really work on images with the same dimensions and or actually b/w images

i think i can use 1 - eucledian distance to get the similarty.
Your code is of grate help, thanks!!

[lyric mountain]

doubt b/w images would work for what u want

a dark enough image would be a plain black rectangle

[eternal osprey]

idk i recently had a lesson about this what i am implementing.

a quick talk with my teacher and he said it would be possible but that i had to normalize my shit

[lyric mountain]

normalizing is just a fancy word for n = val / max

all you need to do is divide the channels by 255f to get a range between 0 and 1

[eternal osprey]

i know yeah

[lament rock]

@lyric mountain @frosty gale if the bot the badge is tied to gets deleted or loses the badge, say bye bye to the badge

[eternal osprey]

isn't normlization n - min / max - min

[lyric mountain]

that's if you have a bottom boundary

[eternal osprey]

i see and standardization is not necessarily in [0,1] but simply dividng by the mean to standardize the outputs?

damn kuu learned me more than my teacher, get yo smart ahh in a classroom and start teaching 🗣️

[lyric mountain]

[eternal osprey]

Wait i got a cool scam story.
I recently got hired by someone to analyze his products and create an overview of which variables played the biggest roles in his sales.
I swear, this analysis was good. I even showed my supervisor and he said it was okay (he is harsh). I had put the analysis on a server for the clients to view it
That mf eventually knocked on our door and demanded a refund.
Weeks later the server is still actively visited by them 😭 .
forgot to put that bitch offline

[lyric mountain]

timebombing is a common tactic to protect oneself from "clever" contractors

[eternal osprey]

what's timebombing

[lyric mountain]

for example, you make a site for someone but they insist to pay after the job's done

[lyric mountain]

but then after delivering the site, they tell you they aren't going to pay yet they keep the site

this ends up with you wasting time and they getting the work for free

timebombing is putting something in the project that WILL cause major disruption unless defused

[sharp geyser]

this is why you always have a backdoor ;)

[eternal osprey]

ahh i see

[lyric mountain]

that's illegal, there are more legal ways

for example putting a timer on the site that progressively reduces the opacity of the body

[eternal osprey]

yeah next time i will create a deadass black on white contract

[eternal osprey]

💀

[lyric mountain]

there's also a story of a guy who made a random word become "unpaid" every day

[eternal osprey]

this is a server that simply displays the notebook used for the data analysis.
Idk how it works, i just have to upload the files there and it creates a link and key for the users.

[eternal osprey]

whahahah that's genious

[sharp geyser]

oh im too patient

I'd make it take a year or two until it finally stops working

[warm carbon]

is it possible to check if a bot can access a specific channel ( with an id ) discord.py

[lyric mountain]

https://www.scs.stanford.edu/~dm/home/papers/remove.pdf not more than this

https://en.wikipedia.org/wiki/International_Journal_of_Advanced_Computer_Technology for context

[quartz kindle]

what kind of access? you can check if the bot can see a channel and also if the bot can type in a channel yes

and if its a voice channel you can check if the bot can connect to it

[warm carbon]

oh ok

i just wanted to know if it was possible to check

[quartz kindle]

yes its possible

[warm carbon]

ty

[lyric mountain]

for read access, you can check for VIEW_CHANNEL, for write access, you can check for WRITE_MESSAGE

for obvious reasons the latter implies the former

but to be safe just check for both

[warm carbon]

one more thing
how do you get the bot's integration role ( discord.py once again )

im trying to check if the bots role is higher than another role and i cant find any answers on the web

[lyric mountain]

it's better to check the bot directly, instead of its role

this is because there can be member overrides that add permissions to the member directly

or for example, if the bot has a higher role

[warm carbon]

oh alr

[eternal osprey]

how hard is it to learn typescript?
I don't like the lack of concerete types in js

no

what's that

[quartz kindle]

what is this fake support server

@solemn latch

[eternal osprey]

nah wait let me play along

i am interested

@full wolf what does the server do my friend

[quartz kindle]

shouldnt be hard

[solemn latch]

Was this already handled?

[quartz kindle]

no idea

[eternal osprey]

no pretty sure he deleted it himself

[quartz kindle]

did the guy delete his own messages?

[eternal osprey]

otherwse he would have received a kick right lol

[quartz kindle]

ye nothing in the mod logs

[quartz kindle]

its pretty much the same as js with very minor syntax changes, the typing system itself is the actual annoying part

[eternal osprey]

but in reality, in any program that i use js, i can simply transform it to typescript and not lose functionality?

For example any libs running on nodejs, i can still use them?

[quartz kindle]

yes

the only thing is

[eternal osprey]

oowh damn, so typescript is just a type extender for js instead of a whole language basically?

[quartz kindle]

typescript might not like libs that dont have types included

and complain that types are missing

but i guess you can force it to compile anyway

and coerce unknown types yourself

[quartz kindle]

its techincally a piggy back language, sort of like c++ for c

it compiles back to js in the end anyway

[eternal osprey]

ahhh i see

damn let me get right into it

you reckon it's possible to learn it in a week?

[lyric mountain]

The only thing that's hard to me is liking the gross syntax ts uses for typing

It's like they put a bandage fix over it but blood leaked and made a weird dry layer around it, then they put another bandage on top

[quartz kindle]

you can learn most of it in a day

then over time you get used to the quirks and improve your usage of the typing system

[frosty gale]

yeah any types can be defined easily and the transpiler wont complain

but if a lib doesnt have types you can still use it without defining types

but its just like using javascript again

[eternal osprey]

🗣️

finally i can enjoy js like it's a proper fucking language

i hated the lack of control over data types

[quartz kindle]

i still prefer using jsdoc

jsdoc in vsc actually uses the typescript engine, so its not limited to the actual jsdoc spec

its not as powerful as ts itself, but allows you to skip the build step entirely and keep using raw js while getting full type checking

vsc is also smart enough to infer a lot of stuff from js are you write it

for example (this is js, not ts)

[neon leaf]

I mean is the extra effort worth saving 20ms

[quartz kindle]

there is no performance difference, its just a matter of productivity

i find it easier to work with jsdoc over typescript

[neon leaf]

Ah okay fair point

[quartz kindle]

makes my work flow faster and more productive

[neon leaf]

I personally think jsdoc is a hassle

[quartz kindle]

i prefer it over the complexity of requiring a compilation step

[sharp geyser]

love the variable names

[quartz kindle]

e d

[harsh nova]

Compilation step is ass but imo worth it for more stable code. JSdoc seems nice

[quartz kindle]

it can produce more stable code and also has the bonus of transpilation, if you ever need that (although these days one would rather drop support for older browsers instead)

but i've also seen it work the otherway around and produce hard to spot bugs that are only discovered when you dive deep into the compiled code

although that mostly happens when the user misuses or abuses coercion, any and !

[harsh nova]

The classic any problem that quickly becomes compasses your whole codebase if you ain't diligent

[harsh nova]

Had one where a pdf to json library that advertised TS type bindings forgot to document an essential function. Took a while to realise that the function was actually there just not typed. That whole library was a mess

[valid epoch]

Whats the best way to learn to code a bot

[quartz kindle]

or even worse, a mistyped function that errors or causes unintended results if you use it as it is typed

[quartz kindle]

there is no "best" way, but a good idea would be to get started with programming/coding in general

[valid epoch]

Should i start with js straight away

[quartz kindle]

its an option, you can if you want to

[valid epoch]

I can understand the discord.js codes like i can see what the code does its just hard for me to memorise it

[quartz kindle]

you dont really need to memorize it, as discord.js has a very extensive documentation on their website

but you need to know a little about js to be able to understand it

you can get pretty far with just the basics, the data types / structures, functions, conditions, loops, etc

[valid epoch]

I seethank u

[lyric mountain]

it's like math, if you're focusing on memorizing things, you're doing it wrong

[past field]

@quartz kindle would optimizing my click war game help with the interaction failed issue?

[quartz kindle]

possible but not guaranteed

[frosty gale]

how slow can your game be for interactions to time out

my local state of the art llama LLM generates tokens faster than the timeout period

[lament rock]

Interactions that are received over the gateway expire all the time when the gateway is asked to reconnect

[quartz kindle]

not only that, there are a lot of possible delays that can happen

which discord doesnt account for

and discord also constantly borks itself

for some reason

i keep getting "unknown interaction" randomly as well

[timid spear]

I am looking for a programmer who wants to partner with me to further improve my bot.

[sharp geyser]

Good luck

[quartz kindle]

i have some info for you tho, i just tested here

i have a command that also uses buttons to navigate between pages

[past field]

👀👀👀👀👀

[quartz kindle]

and if i click too fast, i do get random "interaction failed" errors

so i guess people are clicking too fast and causing discord app errors on their side

[past field]

in the console too? or just with the interaction in discord

[quartz kindle]

the bot never receives anything

its purely an app error

[past field]

from clicking too fast

[quartz kindle]

yes

[past field]

really 👀

[quartz kindle]

let me record

[past field]

ok

[quartz kindle]

not sure if this is how your users are clicking on your game tho

but it seems that a split second before the message changes, the buttons become avalable to click again

and if you click them during that window, it will cause the error

i imagine on mobile this happens more often, since mobile is more laggy and slow in general

[past field]

i can record a game for you and show you, but that would make sense

if that’s the case then i might just make every round last like 5 seconds so they don’t feel like they have to click it so quickly

[quartz kindle]

from what i remember, the game is not really about who clicks faster right?

the game is more about luck

who clicks the right button

[past field]

the game is actually pretty quick.. well structure i’d say lol

[past field]

correct, but it’s set up to be more challenging as the game progresses. round 1 is 3 buttons and lots of time, and as it goes on, it adds more buttons and less time

[quartz kindle]

so there is no real reason to make it so fast, unless there is something like the last person who clicked loses a life lol

[past field]

per round

[past field]

there is sudden death round lol, anyone who loses last at the same time has to tap the sudden death button first to win

[quartz kindle]

well yeah thats going to be entirely dependent on people's internet and phone performance

[past field]

i’m going to make each round last about 6 seconds and announce that change. see if that’ll help

[past field]

mind if i share this video in my announcement?

[quartz kindle]

sure

you can say its a test, no need to make it permanent yet

[past field]

i just can’t believe you complimented the game

i’m proud af of myself

i screenshotted that shit

i stg i did

[quartz kindle]

hahah

[past field]

@quartz kindle i made each round 6 seconds long, but this is how the game looks

i have 2 versions of it. click war where everyone starts with 1 life

click war reverse where everyone starts with 5 lives

this is regular click war

[sharp geyser]

Looks cool

Congrats

[past field]

you should come play sometime!

biggest lobby i’ve seen so far has been 153 people

[quartz kindle]

looking good

i have two suggestions, the final winner message could be a lot more grandious

does markdown work with bots? could at least make some big title

like this

another thing that would be cool, but i dont know if its feasible with too many people, would be to edit the game message to show what everyone clicked on

this way people can troll and roast each other, which makes it more engaging

xD

[past field]

yes, i have some markdowns in the lobby embed where everyone joins

[past field]

what would that look like 👀👀

[queen needle]

Use canvas and make a graph?

[quartz kindle]

basically something like this:

@quartz kindle - Trap
@past field - Extra Life
...

[past field]

oooo that would be funny to see lol

[quartz kindle]

at the same time as the message edits to show what the buttons were underneath, it could also show the names of the people and what each person clicked

[past field]

yeah that would be a little hectic with bigger lobbies, worth a try! i let it be known to all server owners that this bot is in development and will go through changes and updates

[past field]

👀👀👀👀

[quartz kindle]

if there are too many people, you can define some threshold, for example only start showing it once there are less than X people remaining

[past field]

i always forget about canvas

[queen needle]

Like a pie chart(maybe another would be better idk how many options there are)

[quartz kindle]

if there are more than X people, you can instead show X people clicked on a trap and Y people clicked on extra life

and then transition to the full list once the remaining people fit in a single message

[past field]

🤔🤔🤔🤔🤔 that would make it more intense

to watch

[hidden gorge]

quick question could this be more secure?

[sharp geyser]

What exactly are you concerned about

[quartz kindle]

IPs are not a good way to make such a rule, unless you know for sure they are all static ips and never changing

and even then ips can be spoofed

[sharp geyser]

yea

[hidden gorge]

how did i do this???

[hidden gorge]

what should i do then?

[quartz kindle]

apply the rule to something unique

such as an API key

access token

session / username / email / etc

[hidden gorge]

its currently for my api so i could look at adding api tokens but im gonna have to create a system to generate a GUID then store it

[sharp geyser]

if you have emails you can use that

[quartz kindle]

if the only ip that will ever have increased rate limits is your own ip that you control, then its fine

[sharp geyser]

assuming you dont allow multiple accounts with the same email

[quartz kindle]

but if you start adding the ips of people who pay for your service for example, then its not gonna be good enough

[hidden gorge]

the only ips that will be increased will be me and the servers

[quartz kindle]

then its fine, as long as the ips are static

and your host doesnt share them with other clients

[hidden gorge]

it doesnt

also this is how im storing the ips

[past field]

this is also a great idea

[sharp geyser]

sorry I cant do anything with those red marks there

can you please remove them

:)

[hidden gorge]

nope

aint doxing myself again

[past field]

@quartz kindle you should come play a few times man! i have a database set up to grant click war coins too and you can purchase lives from the shop lol

[past field]

in response to this

[civic scroll]

is this js

[neon leaf]

It's json

[civic scroll]

i mean as in the runtime that handle this

was about to have a crazy idea of encoding ip addresses as number literals

[sharp geyser]

I mean, using IPs isnt good no matter what anyway

Especially since hardly any ISP use static ips nowadays

[civic scroll]

yes

that would be one good day to make your server incredibly slower

by increasing the size of json file

[hidden gorge]

It's json

It's running surprisingly fast

[civic scroll]

it won't be, once the size goes up

i suggest you use a database engine for that

i mean it's fine if you're only going to store a few ips

at first i thought you were storing the ips that got rate limited in there and i was going to scream

[quartz kindle]

its a config json, its not gonna be written to at runtime

[sharp geyser]

yknow tim

you say that but its tw we are talking bout

anything is possible with him

[frosty gale]

what if he one upped everyone and set up a file system listener for the config file to detect saves and updated the config in memory

[sharp geyser]

yea no hes not doing that

doesnt even know how to hash passwords

[digital swan]

leave him alone hes actually developing a revolutionary database engine

[quartz kindle]

lmao

[alpine sentinel]

Hi

[deft wolf]

Yo

[pine willow]

i was bored??? and created an copy of spy.pet but for twitch

[spark flint]

[past field]

so the only perk to being verified is being able to have my bot in more than 100 guilds

[deft wolf]

• monetization and app directory

[pine willow]

[frosty gale]

about the spy.pet thing people are making too much of a deal about it

discord servers are largely public places and so you shouldnt expect any privacy

theres probably 50 different spy.pet instances running right now that just arent public

[pine willow]

yea i know. I was just bored

let my brother sky have his shine 🗣️

(i am just kidding Chloe, pls don't be mad )

[frosty gale]

i rarely get mad

more commonly disappointed

[surreal sage]

js' promise.all automatically handles threading right

[vivid fulcrum]

no, node is single threaded

it supports parallelism thanks to its event loop, if that's what you're aiming for

[eternal osprey]

hey, how do i create a big blue line at the bottom of the embed?
Some servers have it, it looks cool.
I know it's an image they set using .setImage(), but what should the image dimensions be lol, my images i put in take atleast half the screen.

[digital swan]

maybe like 5x512

[quartz kindle]

js is non-parallel, all its forms of concurrency including callbacks, promises and more, they are all non-parallel concurrency

[surreal sage]

oh yea that's what i meant 😓

[quartz kindle]

therefore no threading is involved

[surreal sage]

let me rephrase then

does promise.all automatically do parallelism

wait im actually blind

[quartz kindle]

it does non-parallel concurrency yes

[digital swan]

it runs them all at the same time

but not concurrently

[quartz kindle]

its the other way around lmao

[digital swan]

wtf

[quartz kindle]

it runs them concurrently but not at the exact same time

[digital swan]

yeah thats what i mean

[quartz kindle]

bits and pieces are still sequential

[surreal sage]

promise.all = fn1().then(fn2).then(fn3).then(…)

[quartz kindle]

no

promise.all = fn1(); fn2(); fn3();

[surreal sage]

ohh

[quartz kindle]

more specifically:

const results = [];
fn1().then(result => { results.push(result); if(results.length === 3) { return results } })
fn2().then(result => { results.push(result); if(results.length === 3) { return results } })
fn3().then(result => { results.push(result); if(results.length === 3) { return results } })
``` sort of like that

of course that return in there doesnt actually work, but you get the gist of it

[surreal sage]

can you perchance name a library that adds the parallelism functionality?

[quartz kindle]

if you want true parallelism akin to threading, the only way is child process or worker thread

[surreal sage]

no multi threading 😓

i want to iterate over my users (like 15-20) in a database and run a method on them but efficiently

[quartz kindle]

you can use Promise.all()

[surreal sage]

just KISS it?

[quartz kindle]

the promises in Promise.all() are run "concurrently", just not in "parallel"

lmao

[surreal sage]

yea fuck it ig ❤️

[quartz kindle]

put it this way, if you have 3 async db calls, and you put them in Promise.all(), they will be made at the same time yes

more specifically, they will "start" in sequence, but once the first call enters "waiting" mode, the second call starts immediately, it doesnt wait for the first call to finish

[surreal sage]

im worried about resource hogging

like, if you have 4 asyncs doing very cpu intensive tasks

and they'll all be slowed down a ton if the cpu cant keep up no?

[quartz kindle]

async and cpu-intensive is mutually exclusive, you cannot have async cpu-intensive

unless the cpu-intensive part is in a different process

[quartz kindle]

for example

you cannot run while(true) {} two times at the same time

1 while(true) will make your process use 100% cpu, and it will never even start the second while(true)

cpu-usage is blocking, no matter how async you make it, it will block the process
