development

[proven lantern]

yea, see that little spike? that was handled automatically

[solemn latch]

yeah, I think thats the part everyone forgets

[prime cliff]

200ms is on average what most apis handle

[proven lantern]

and those are the cold starts

[solemn latch]

Goof around with cf workers for a bit.
Its like 100k requests free a day.

Its really interesting stuff

(in terms of discord bots, thats 100k commands run per day free)

[wooden ember]

just calculated it and it costs about £5.39 a year

not as bad as i thought

[prime cliff]

My api averages at 150 ms with image gen around 400 - 500 ms

[wooden ember]

I used to run my bots and stuff on an actual pc but that was like 200 quid a couple years ago and I can't justify

[proven lantern]

not too bad

[wooden ember]

indeed

[proven lantern]

when my lambda is warm it can respond in less than 2ms

[wooden ember]

my ping to the discord api is about 30ms lol

[prime cliff]

That might mean it's cacheing the response

[proven lantern]

it can't. it's sending the unique interaction url token along. any caching would break it

[solemn latch]

Mine was around 5ms on cf workers when it didn't have to hit the database, which was about 40% of the time.

[prime cliff]

I mean it wouldn't really take much to just send the interaction token then xD

[solemn latch]

serverless is fast

[proven lantern]

i'm not hitting a DB either. just verifying the discord signature and then invoking another lambda

[proven lantern]

it's doing some crypto stuff

[delicate zephyr]

that and more scalable lol

docker has built in load balancing if you use hostnames and container networks properly

[prime cliff]

At that point though if you really need scaleability you would just go with AWS/GCP/DO

[delicate zephyr]

yea

self-managed is more fun tho

:^)

and way cheaper if you do it right

[prime cliff]

Working on a docker UI alternative similar to portainer, would this be a good permission set to use?

[delicate zephyr]

just skimming over it yes

honestly once you have this semi stable I might use it for our topstats deployment for easy log access

portainer is fine but its a bitch sometimes

[prime cliff]

Yea it has its annoying issues and the permission system in it is fked and no 2FA either

[delicate zephyr]

yarp

we have 25 containers now (8 of which are github self-runners) but still

would be nice to see logs without using ssh

for mobile access etc

whats the frontend written in?

[prime cliff]

asp.net blazor SSR

Pretty good for dashboard type applications and good for security and real-time stuff like this

[delicate zephyr]

Man making me wanna dust off my .NET experience just to contribute 💀

I havent used .NET in like, 8 years lmao

[prime cliff]

Dang

[delicate zephyr]

not saying I couldnt it would just take me reading docs and trial and error and code review tbf

[prime cliff]

If you have any like suggestions or features i could add into this project let me know 🙂
Here's a preview version too https://devspace-demo.fluxpoint.dev/

[delicate zephyr]

you got a notion or a public board of tickets of whats already planned?

[prime cliff]

Oh the demo is broken no team

[delicate zephyr]

im working on a replacement for ticketbot rn

lol

gonna be fun

[prime cliff]

Ah nice

[delicate zephyr]

you can create one

nvm

:^)

UI is hella nice

if the background customizable? @prime cliff

[prime cliff]

Yup

For demo there is a specific preview for it with url

[delicate zephyr]

Oh noice

[neon leaf]

first real rust project 🔥

[frosty gale]

Is there a performance difference (if any) to instantiating a relatively simple object (class with get set members) and a struct in c#?

I know in compiled languages structs and simple classes get optimised down to a simple stack allocation with the members populated in compile time (assuming we are setting members compile time) but not sure how c# handles this

[ivory kayak]

there is. in c# sturcts are value types allocated on the stack (when they arent part of a ref type) avoiding garbage collection

while classes are ref types allocated on the heap, potencially leading to gc overhead

structs are faster for small objects because it doesnt require heap allocation or garbage collection

oversimplified

[prime cliff]

You don't really need to worry that deeply about performance when using C# it's pretty well optimized already :/

[radiant kraken]

so based

chat is this real

my first ever model from scratch seems to spit out exponentially worse output in every iteration

[neon leaf]

im pretty proud even though most code is still pretty mid https://github.com/mcjars/mcvcli

[radiant kraken]

looks okay for a first rust project

could have some refactoring but overall looks good

[neon leaf]

thanks

[craggy pine]

@harsh nova

[bitter granite]

i amma try it

[deft wolf]

steamne moment

[harsh nova]

Thx

[craggy pine]

np

[bitter granite]

oh no i failed to get 50 usd

[deft wolf]

[bitter granite]

I amma blame u for no reason then

[lyric mountain]

it's learning, just backwards

[radiant kraken]

the thing is this is the dataset 😭

[radiant kraken]

chat is this real?

[lyric mountain]

given enough time it'll eventually print all digits of pi

[radiant kraken]

WAIT I THINK IT'S FINALLY LEARNING

left is expected result, right is predicted value

wait nevermind??

[wheat mesa]

Is this for springs?

[radiant kraken]

wdym by for springs?

[wheat mesa]

Like, force applied to the spring and the distance it stretches

For calculating the spring constant

[radiant kraken]

oh right yeah

"Given a dataset of the relationship between the extension of the spring (x) and the force given (F) in the Hooke's Law experiment is obtained as follows:"

[wheat mesa]

Yeah

Wdym by “model” here?

You can calculate this definitively using physics :p

[radiant kraken]

we were asked to optimize a model with gradient descent with that dataset for 4 iterations

[wheat mesa]

Oh this is ML stuff

[radiant kraken]

yeah

[wheat mesa]

Lucky

[radiant kraken]

not physics lol

[wheat mesa]

I haven’t had an ML class at all yet

[radiant kraken]

NOOOOOOOOOO

i'm screwed

[wheat mesa]

Never even done ML on my own

Although I’ll hopefully be doing it soon

Trying to get into a quant research program at my school run by a club here

[radiant kraken]

i kinda made a simple pseudo machine learning model from scratch in C

it kinda worked for the example dataset provided in the lecturer's presentation

this is with 1,000 iterations btw

[wheat mesa]

wish I had an ML class early on

I'm senior status this year and still haven't taken one

[radiant kraken]

i'm honestly unsure if it worked with this dataset

we were asked to perform only 4 iterations but even this 1,000th iteration doesn't even look good

😭

when i tweaked a single digit it suddenly becomes like this

perfect

[radiant kraken]

wish i didn't have an ML class in my first semester 😭

such a huge jump from programming basics

[prime cliff]

I've literally never touched any AI/machine learning programming, chatgpt or co-pilot
I'm a pure dev

[wheat mesa]

I mean assuming that this is a linear regression model, I’d imagine it should be able to handle a linear relationship with ease (judging on the name)

Actually nvm I’m stupid

[radiant kraken]

here's what it should typically output

[earnest phoenix]

🧌

[neon leaf]

ci?

[bitter granite]

Go catch your cargo
The cargo is on the run

[wheat rose]

does anyone know why this embed isn't showing a video:
https://ftcscrimmage.org/post/B0CUYY

ive added the video meta tags, you can confirm that by viewing the page source

[queen needle]

Idk if it is much help, but these are all of the tags for a site which does embed videos correctly

https://discord.mx/i/ClvdqcB9Sj.png

[wheat rose]

thanks

[vocal knot]

why are you using </meta> after each one

[wheat rose]

does that matter

[vocal knot]

idk LOL

also try direct file url

with .mp4

[wheat rose]

got it

[vocal knot]

also there seems to also be twitter:player

found this just now https://github.com/TheLovinator1/discord-embed

[wheat rose]

ill check it out thanks

[surreal sage]

pls god dependabot never make this pull request ever again

[quartz kindle]

never bump dependencies without testing and reading changelog

[pearl trail]

[violet flicker]

where's the editing option on top.gg page

like i want to use css to change bg and stuff

where can i find it

[bitter granite]

I dont see a bot with your id approved
when the bot is approvedm there is an option to click edit on the bot page

[violet flicker]

i am on edit page

where can i use CSS

in description?

or anywhere else

[deft wolf]

-htmldesc

[deft wolf]

Yea, you can use HTML and CSS in long description

[bitter granite]

-htmldesc

[gilded plank]

You can achieve this using Markdown or HTML in your bot's description. You can ask in #development for help or use this HTML and Markdown cheatsheet for more resources.

[violet flicker]

ohh thanks!!

[bitter granite]

yeah forgot

been trying

[violet flicker]

i just edited and when i clicked on save it popped up!

Invalid CSRF Token. Please refresh the page and try again

wrong reply

[violet flicker]

😭

[bitter granite]

# give <@&1230605757486202990> luca access (including ban)

[bitter granite]

can u send sc in #support

[small tangle]

But thats what gives me adrenaline 😔

[deft wolf]

I love this thrill when I do not know if my code will continue to work or lunch into space

[violet flicker]

what can be the issue when i preview the code in vscode it's like this and quite opposite on top.gg

[earnest phoenix]

An overview of your code would help.
All we can say now is; yes it's different, use iframes.

[violet flicker]

@earnest phoenix here it is

i want this to be on my bot's page

what type of link can i use in iframe

github is not supported

[violet flicker]

Anyone help!

[earnest phoenix]

any website

[earnest phoenix]

it is, if you host your website/file

top.gg's bot description is not a website, it's a description

markdown description with few supported html elements and attributes

so either work with the limitations

or host the html page using e.g. GitHub Pages and then use an iframe

[earnest phoenix]

And there's something called patience

[violet flicker]

@earnest phoenix Thanks for your help. I hosted it on github then took out iframe in long-description

can i do the same in shorter one?

[deft wolf]

No, the short description does not support HTML

[earnest phoenix]

why would anyone do that

horrible ux

[violet flicker]

💀

one last

ques

can i make it bigger?

[earnest phoenix]

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe

[lyric mountain]

do note that the width is at its maximum in that screenshot

you cannot go over the sidebar

[pearl trail]

unless you do some css stylings

[lyric mountain]

I mean, u still cant cuz you'll get banned off topgg lul

[pearl trail]

there's limitation on styling?

[deft wolf]

You can't do some things

Like blocking buttons or removing elements

[pearl trail]

nah, i didnt say anything about blocking buttons/removing elements

there's a way to make that full width, like display: block, but the buttons are at the very bottom (bottom of review). the other way is use flex-direction: column-reverse. that'll make the buttons on top, but need to style them to become row instead of column

[solemn latch]

TBH, I wouldn't make it bigger than that anyway.
I would change the styling on page like Mimu does.

https://top.gg/bot/493716749342998541

Makes it look like the desc is much more incorporated

[prime cliff]

Bruh there's literally a button on there that just redirects to Discords own app directory

Also the bot name is gone

[vocal knot]

@solemn latch

[solemn latch]

Now thats amazing

Its intresting because it just disapears for me

[prime cliff]

Wait what

[vocal knot]

it seems to be something with the "css-rd8i1m" class cuz without it the text shows up

[solemn latch]

anti mod code

[solemn latch]

css-rd8i1m is setting content to ''

[vocal knot]

oh

[solemn latch]

I mean, she explicitly set that, so Idk

[deft wolf]

Weird thing to do tbh

[solemn latch]

Reported it to iara, probably unintentional.

👀 anyone want to review my sql schema?
I'm pretty bad at database structures, going to start learning a bit more proper approaches to table structure. Might be fun to get feedback before I really start learning.

[vocal knot]

I'm curious LOL

[prime cliff]

Yup sql is fun to break

[solemn latch]

context for what this is for: #general message

I'ma post the sql on pastebin, its long

https://pastebin.com/mTTuqRDF

Things like attachments, reactions are not included yet

[lyric mountain]

pastebin

[solemn latch]

yeah ikr

I havent used pastebin since highschool

[neon leaf]

https://pastes.dev 🙏

[lyric mountain]

also what the hell is happening there

[vocal knot]

scams lots of them

[solemn latch]

no moderation pastebin, woot

[vocal knot]

it's been awhile i think

i first saw theses quite awhile ago

[lyric mountain]

woo, you could use some not nulls there

content u can use a varchar column with size set to whatever is max discord length

same for other text columns

[solemn latch]

Should not nulls be used even when things may be empty strings?

[vocal knot]

people really post a review instead of join a discord server for help LOL

[deft wolf]

At least it's 4 star review

[lyric mountain]

well, not when it's a nullable field in discord, but when it's a required field

like username

[vocal knot]

yeah at least

[solemn latch]

username may be empty

or well null

[lyric mountain]

username cant be empty

[solemn latch]

private users will have null usernames

But yeah, some things are not null.
tag names should be filled.

[lyric mountain]

private users?

[solemn latch]

yeah, so on the website users by default wont show their actual username.

It will be generated per thread, randomized.

I dont need to track those users usernames

[lyric mountain]

ah, not private, anonymous then

[solemn latch]

yeah

Kind of private, since they wont have a profile on the site either

[lyric mountain]

you could still make it not null, just dont fill author_id on thread

a null column still takes space

[solemn latch]

alright, good ^-^

[lyric mountain]

the timestamps could also have a DEFAULT CURRENT_TIMESTAMP to reduce insert payload size

[solemn latch]

good point

[lyric mountain]

oh also, I saw answer_message_id BIGINT on threads

does this mean that they can only have one answer?

oh is it like stackoverflow?

[solemn latch]

Yeah, one marked answer. Figured it would be easiest

[lyric mountain]

yep, that's fine

well, the rest seems fine, just replace the text fields with a bounded varchar where possible

and if you plan on adding more flags in the future, you could use a bitfield instead

an int bitfield can hold 32 booleans at 1/8 the size of 32 bool columns

[solemn latch]

I've never worked with bitfields in a database. great thing to learn

[lyric mountain]

they're just boolean arrays but in a number

(bitfield >> n) & 1 == 1 is the same as doing array[n]

[solemn latch]

What about the circular fkey references?

Threads referencing messages, messages referencing threads.

Is that bad?

[wheat mesa]

That’s what mapping tables are for

Or maybe I’ve misunderstood your intent here

Many to many relationships?

[lyric mountain]

unless you want threads and messages to have a 1<>1 relationship, only one side will have a reference

also it'll be impossible to insert data when it has circular FK (unless you bypass constraints, which u shouldn't)

[wheat mesa]

Yeah if the thread has many messages, and the message has one thread, then the message table will have an ID to the thread row that owns it

[solemn latch]

CREATE TABLE threads (
    thread_id BIGINT PRIMARY KEY,
    channel_id BIGINT REFERENCES channels(channel_id),
    thread_name TEXT,
    answer_message_id BIGINT REFRENCES messages(message_id),  
    owner_id BIGINT,           
    guild_id BIGINT REFERENCES guilds(guild_id),
    last_active_at TIMESTAMPTZ,
    is_locked BOOLEAN DEFAULT FALSE
);

CREATE TABLE messages (
    message_id BIGINT PRIMARY KEY,
    thread_id BIGINT REFERENCES threads(thread_id),
    author_id BIGINT,
    guild_id BIGINT,
    content TEXT,
    timestamp TIMESTAMPTZ,
    edited_at TIMESTAMPTZ,
    deleted_at TIMESTAMPTZ
);

Thread has many messages

One message can be the answer in the thread

[wheat mesa]

This looks fine I think

I'm assuming that answer_message_id will be nullable?

[solemn latch]

yeah

[wheat mesa]

Yeah that should be fine then

[lyric mountain]

oh, right, in this case it's fine

[wheat mesa]

You could run into issues if it weren't nullable, since the message that answers the thread has to be created to reference it in the thread table, but the messages wouldn't exist before the thread

But since it's nullable this is fine

[lyric mountain]

oh, u forgot one thing btw

[solemn latch]

What about marking a message as the original post?

I'd mark that in the messages table right?

[lyric mountain]

status columns, to mark them as deleted (tho can use deleted_at for this)

[wheat mesa]

Hmmmm, I'd probably mark that in the threads table

Assuming that your threads work similarly to discord threads, right?

[solemn latch]

all of this is discord forums

context: #general message

[solemn latch]

Yeah, that was my intention, when a threads deleted just delete everything. messages marked with deleted_at

[wheat mesa]

I would mark the original message in the threads table with a FK to a message row

Since the message exists before the thread is created

[solemn latch]

👀 is that how it works in fourms?

I think both are passed in the thread create event, but I havent looked yet

[wheat mesa]

Honestly I have no idea how discord does it. I am just thinking from a standpoint of how I would model this relationship in a relational db

If possible, I'd do it this way bc otherwise you're just going to have a ton of conditional checks later on if you try to make this from the messages standpoint. Having a column for something like is_original_thread_message in my mind would be messy, since most of your rows are going to show false for this

Instead of just directly accessing the original thread message from the FK on the thread itself

[solemn latch]

I wonder how next does it, they dont mark this at all in their schema

https://github.com/rafaelalmeidatk/nextjs-forum/blob/main/packages/db/schema.ts

[lyric mountain]

putting it in the header table is the best option

[solemn latch]

using the oldest message as the original?

[lyric mountain]

create thread -> create original message -> link both

[solemn latch]

Yeah, they just get the oldest message in the thread.

https://github.com/rafaelalmeidatk/nextjs-forum/blob/eec1a1447c8f70dedb11855f08e9a4dcb73c812d/apps/web/app/post/[id]/page.tsx#L57

I dont see any problems with this, since discord fourms require you to send a message when creating the thread.

[wheat mesa]

Ohhhh I was confused on how threads work

I was assuming that you HAD to have a message exist before creating a thread on it

[solemn latch]

yeah, its backwards in fourms

[wheat mesa]

thanks for the consistency, discord!

[solemn latch]

Much better method 😄

I got some good notes, thanks guys ^-^

[wheat mesa]

I used to be a big relational db hater

Now that I understand it, they're awesome

[solemn latch]

My issue is I don't really understand anything.
I can make them but I never know if its right.

[wheat mesa]

You'll get a hang of it pretty quickly

Or at least the basics

Optimizing is a little bit more difficult, like figuring out when to create db indexes, or how to optimize certain queries, but the structure is pretty intuitive after some practice

[solemn latch]

Yeah, indexs I'll do last. I'm not sure what I'll need indexed until then.

[wheat mesa]

I would be clueless if it weren't for the fact that I was forced into using relational DBs by my internship, which is something super valuable to have

If you ever make a web api, check out ASP.NET with EF Core

I love how structured it is, very intuitive to understand. Very easy to separate out your business logic from everything else

[solemn latch]

On this topic, how do I actually document bitfields?

Just in whatever file handles the bitfield?

[harsh nova]

Lol I've thought about adding that as a paid module for thread watcher

[solemn latch]

Its a fun side project 😄

[wheat mesa]

Honestly it's a pretty good idea

[harsh nova]

Yeah for sure! Kinda made a bot like that alr but it worked with GitHub issues

[wheat mesa]

I've been so busy with stuff that I haven't had time for side projects 😦

[harsh nova]

Do you can right click a message in a thread and press "add to GitHub issue"

[wheat mesa]

Going to try to get into ML stuff soon with financial models

But honestly no idea where to start

[harsh nova]

That part is always the hardest part

[solemn latch]

My issue with discord is nothing is indexed, so i cant just google things from a specific discord.
Discord search sucks 😭

[wheat mesa]

I have been watching a video series made by my school's quant finance club on the black scholes model and geometric brownian motion

Which I'm actually enjoying quite a bit

But still going to take a while to figure out, I'm thinking maybe I start with a project that tries to estimate values for drift and volatility given a stock's historical data

[wheat mesa]

Yeah discord search is really unreliable

I'll have some times where it works, and most times where it doesn't

[solemn latch]

It would be a great feature for discord to implement. restrict it to boost level 3 servers or something.

So, just implement it into a bot. Discord loves stealing bots ideas.

[queen needle]

I remember seeing a bot that did this with normal text channels or something like that

[solemn latch]

Nextjs has a bot for it https://github.com/rafaelalmeidatk/nextjs-forum

Its just only for one guild.

[wheat mesa]

It would be probably somewhat expensive to host for multiple guilds, plus probably requires customization per-guild

[solemn latch]

Yeah, thats my target.

[wheat mesa]

But I could actually see something like this making some money, especially for bigger servers

[solemn latch]

hopefully ad supported, but I'll throw in a use your own domain feature to premium servers.

[queen needle]

https://github.com/AnswerOverflow/AnswerOverflow

Is what I was thinking of

[wheat mesa]

Either way, nice project to put on a resume 😉

[solemn latch]

sick.

[frosty gale]

thanks for the help google

why do they even have this open if they dont answer to anyone but probably companies that make them money

[deft wolf]

They are working on this case tho

[frosty gale]

i'll check back in a year to see if they are still working on it

[deft wolf]

It must really be something serious that it takes them so much time

[neon leaf]

🔥🔥

[wheat mesa]

this is sick

[neon leaf]

3 hours pain getting named pipes to work

use ipipe::Pipe;

pub fn status(pid: Option<usize>) -> bool {
    if pid.is_none() {
        return false;
    }

    let pid = sysinfo::Pid::from(pid.unwrap());
    let sys = sysinfo::System::new_all();

    let process = sys.process(pid);

    if process.is_none() {
        return false;
    }

    let process = process.unwrap();
    for value in process.environ() {
        if value
            .to_str()
            .as_deref()
            .unwrap()
            .contains("/.mcvcli/java/")
        {
            return true;
        }
    }

    false
}

pub fn get_pipes(identifier: &str) -> (Pipe, Pipe, Pipe) {
    let stdin = Pipe::with_name(&format!("{}_stdin", identifier)).unwrap();
    let stdout = Pipe::with_name(&format!("{}_stdout", identifier)).unwrap();
    let stderr = Pipe::with_name(&format!("{}_stderr", identifier)).unwrap();

    (stdin, stdout, stderr)
}

this ended up being the entire thing

[pine willow]

Just recode it for multiguild

[solemn latch]

Thats boring

😄

[covert gale]

https://www.answeroverflow.com

ah, someone posted answeroverflow already

[solemn latch]

Yep

[amber quiver]

I need ideas to add into my ticket bot, any ideas?
I’ve switched it up entirely and gone for the use of forum threads instead of multiple text channels and it’s working relatively smoothly

[pearl trail]

oh god im so lucky, a user posted the solution 5 hours ago on last 2 years issue about a problem i got https://github.com/cfug/dio/issues/2060

[radiant kraken]

meanwhile me using C having to scour through forum threads from 1997

[pearl trail]

lmao, at least most of threads from 19xx still relevant to C now, unlike frameworks like flutter, that mostly does major updates every some years

[delicate zephyr]

it all fairness to C

it's like the easiest language to read if you're just starting out

because most of the time it just makes sense lmao

and yea the 19xx threats are the best

[pearl trail]

yeah

[radiant kraken]

most of them weren't even threads

they were in the form of emails

that shows how old they are

[spark hawk]

bros maxing out the salary pathway

good luck

[rigid maple]

Hello, I created such a background, but when the resolution changes, the curved lines shift and the triangular shapes in the background are distorted.

When the resolution changes:

No matter what, I want the triangular shapes in the back to remain intact.

[wheat mesa]

that’s the goal

[long marsh]

Haha yeah – when would you not?

The only way you wouldn't care too is if you already have money and/or are complacent with your position in life

[spark hawk]

if you wanted to do something fun and meaningful

but I come from an upper middle class family and haven't really struggled for money

[long marsh]

Exactly - spoken like someone who hasn’t struggled. Nothing against you though… happy for you!

[spark hawk]

alr bro

we'll see where I end up

[long marsh]

I appreciate that you recognize your advantage though

[sturdy depot]

does anyone know how to do so when you type a command in the discord server it saves it in a code?

[pearl trail]

i don't quite get what you meant. save what? is it like command tracking, to track which commands is used etc?

[sturdy depot]

sorry for late reply but lemme explain
so for example with my bot someone does the command !addswear
i want that swear to be automatically saved in the code so when i restart the vps it saves the swear word and the owner dosent have to add it again

[pearl trail]

ah, it's better to use database, a very simple one can do the job, like better-sqlite3. i'm pretty much sure it's not recommended to edit code in runtime, by that i mean like you update const badwords = [a, b, c, d] to const badwords = [a, b, c, d, e, f]. if better-sqlite3 is still too much, the very very simple way is to use txt files and play with it. like

a
b
c
```. tho using file "db" like txt/json is not recommended

[sturdy depot]

oh ok

thans

ima tell u if it dosent work

[pearl trail]

oke

[wheat mesa]

JSON/text DB is a bad idea

Use a proper database for this

[pearl trail]

yeah, i said that at the end of msg

[wheat mesa]

Just wanted to emphasize

[sturdy depot]

is text risky?

[wheat mesa]

Yes

[sturdy depot]

well why

One concurrent write and it’s going to fuck up your file

It’s also slower than using a database that’s optimized for exactly this purpose

[sturdy depot]

oh ok

[wheat mesa]

Plus learning a relational database is always a good thing 🙂

[sturdy depot]

i use ai to code my bots so you kinda confused me but whatever

[wheat mesa]

ouch

If you actually want to learn, using AI is detrimental. If you don’t care about that though, go for it

It’ll be difficult to get very far with it though, I must warn you

[fast marsh]

True, once I discovered MongoDB I've used nothing but that and love using it

anyway atleast my bot aint broken now

btw is this risky to keep or should i try to remove it?

[solemn latch]

probably using discordjs, latest version has 3 moderate vulnerabilities

[sturdy depot]

so is it safe?

and yes im using js

[solemn latch]

discordjs suggests they don't affect bots, but its up to you to determine if its okay for you, or if you want to fix them.

[sturdy depot]

oh ok then idgaf

[frosty gale]

the old android fastboot/recovery logo is very cursed

[frosty gale]

moderate is probably stuff like denial of service so thats the worst that can happen

but not trivial to exploit

[lyric mountain]

if it's only 3 I'd try to solve it

those things tend to snowball fast if you ignore

[frosty gale]

yeah chances are there are no breaking changes so everything should still work

[sharp elbow]

Erm what the skibidi sigma, severity of vulnerabilities should be considered if they are severe enough to pop up, however I don’t see anything possibly able to be exploited from a Discord bot unless it’s connected to a db which may be exposed or a web server

[pearl trail]

i'm curious, if you use github actions, how do you test it? because sometimes it won't work the first time it got created, so fix and fixes are being made. if we want to fix it, a commit need to be made and actions will re-run. that'll clutter commit with "fix: workflow" etc

[solemn latch]

I need this info too.

[digital swan]

I make a lot of commits with very angry commit messages

[lament rock]

[earnest phoenix]

Just be sure to not publish some things by mistake

cc @solemn latch

[solemn latch]

cool

[pearl trail]

interesting… thank you guys! 🙏

ill try them

[prime cliff]

I would argue it's better to make a publish branch so you can just merge from main -> publish and then build from there tbh

[sharp geyser]

Anything CI/CD related is beyond me

especially when it coems to actions

Props to you guys who know how it works

When it comes to access management, especially when related to role based access management, how do you guys handle it from an api standpoint to protect resources?

My idea was, my auth server allows me to designate roles, which is attached to user info when they introspect to verify the access token. I can then check the roles based off the required roles for the resource being requested. I'd use some sort of enum on my api, since I also want to be able to give access to resources if they are of a higher role, like a moderator or developer.

Something like
if granted_role >= required_role then give access else return unauthorized

I'd need to make some wrappers to parse the introspected data into proper format, and make sure the roles are typed properly so I can do the whole greather than or equal to check

[wheat mesa]

Are you using asp.net identity? You can use the Authorize attribute on each controller endpoint afaik

[sharp geyser]

How so?

[wheat mesa]

https://learn.microsoft.com/en-us/aspnet/core/security/authorization/simple?view=aspnetcore-9.0

[sharp geyser]

Also no im not

[wheat mesa]

Ah nvm then

[sharp geyser]

Not for the backend

The backend receives an access token in the Authorization header

Its easier just to parse it myself

[wheat mesa]

What backend are you using?

[sharp geyser]

Im still using aspnet

[wheat mesa]

Use identity with it

It’ll save you a ton of time

[sharp geyser]

Why?

[wheat mesa]

Doing auth by hand is a PITA

[sharp geyser]

Im not implementing a full auth in the backend

the frontend is where most of the auth is

[wheat mesa]

You can set up a middleware to parse the auth token

[sharp geyser]

the backend only handles giving out resources if they are authorized based off an access token

[wheat mesa]

Also your frontend should never ever handle auth

[sharp geyser]

[wheat mesa]

It should store an access token that is given to it and associate it with every request, but other than that, your backend should never trust your frontend

[sharp geyser]

Thats how 90% of people do it

At least when they are doing SSR

[sharp geyser]

Correct

Which is why it takes the access token given and introspects

It will only ever give out resources if the token is validated via the introspect endpoint

Otherwise its 403

[wheat mesa]

OAuth2 grants an auth token -> frontend stores the auth token -> sends it with each request -> backend finds the user that this token is associated with and it’s roles (or you can use JWT claims if that’s how you’re doing it)

[sharp geyser]

Correct

Which is what im already proposing doing

[wheat mesa]

Since the JWT is signed with a secret key from the server, the client can’t maliciously fake the data

[sharp geyser]

Right

[wheat mesa]

Ok I misunderstood what you were saying

You said frontend handles the auth

[sharp geyser]

Well technically yes

[wheat mesa]

I was under the impression that was your only layer of security there

[sharp geyser]

Its initiated on the frontend, but its done server side in nextjs

[wheat mesa]

Yeah then the backend is handling auth

[sharp geyser]

I guess yea

I consider anything nextjs related frontend 💀

[wheat mesa]

Frontend handling auth would mean like “If the roles don’t match, I don’t allow them to make a request to endpoint [x]”

[sharp geyser]

My aspnet api will take the access token and introspect it before allowing any resource to be given out

But resources are also role based

[wheat mesa]

And why not use asp.net identity? It handles stuff like role based auth for you

[sharp geyser]

Because I don't see a viable way to do it with how we currently do things

Right now the process is

Login on nextjs app -> server side of the app will redirect to auth page -> get redirected back to the nextjs app on successful login -> tokens saved to localStorage

[wheat mesa]

Why so many steps? You’re running two different servers?

[sharp geyser]

We have the nextjs app and then the aspnet api

[wheat mesa]

And why is it a nextjs app and not just plain react

Nextjs is a server

[sharp geyser]

null recommended using nextjs

[wheat mesa]

You don’t need nextjs unless you plan on doing SSR or something like that

[sharp geyser]

Ima keep it a buck with you, frontend is not my specialty

so idk what we need

Im a backend nerd

[harsh nova]

Im right there with you. Also using nextjs for frontend with a rust backend

[sharp geyser]

I simply went nextjs because easy route stuff

[harsh nova]

Yeah same and the css / js bundler

[sharp geyser]

yup

[wheat mesa]

Nextjs is server side rendering/api backend. Use something like React Router if you want routes

[sharp geyser]

[harsh nova]

Yeah I'm a bit silly

[sharp geyser]

Bro at this rate we ain't doin shit

[wheat mesa]

I think you CAN do a static site gen with nextjs, but it’s not what it’s intended for fully

[sharp geyser]

I dont even want to swap rn

I don't know if we need nextjs fully or not yet

since I barely know what SSR is

[wheat mesa]

SSR is when your client makes a request to the server, and the server renders the HTML before sending it back to the client

[sharp geyser]

See idk if we need that or not

Im not a frontend guy so I can't make the call

[wheat mesa]

This is different from a SPA like base React because the client makes a request, and the server responds with all of the javascript that then gets run on the browser to render the HTML

SSR is good for SEO because it renders entirely server side and the client needs to do basically no work

But most web crawlers now can handle SPAs for indexing

[harsh nova]

Oh really? Only reason I used nextjs was so that it would be crawlable

Probably switching to just regular old react then as I've never gotten nextjs self hosting working right on my server

[wheat mesa]

Not all web crawlers will run the js but major indexers like Google will absolutely do it

[sharp geyser]

Google is the only one that really matters

its what 90% of the world uses

💀

[harsh nova]

Google and Bing imo

I think ddg gets their results via bing if I don't have stupid

[wheat mesa]

Otherwise it’ll be annoying to run two servers if you don’t need SSR

[sharp geyser]

Right

but I still dont know if we need SSR

I'll have to talk to null

Which is a conversation im not excited about since we've swapped frontend stuff like 5 times now

[wheat mesa]

SSR is primarily for SEO or to reduce load times on large pages/slow computers

[sharp geyser]

I mean

chances are we may make use of it

especially for a marketplace app

[wheat mesa]

For most apps an SPA + REST API is more than enough

You’ll also have to host this nextjs server :^)

[sharp geyser]

@wheat mesa if im am using React + my aspnet backend

How do you recommend I handle auth?

I know using the Identity package

but the only time I ever used it was but once and even that was handled in blazor SSR

I think I have an idea on how to use it but im not certain

[pearl trail]

you fully rely on the backend

[sharp geyser]

Would my frontend just make a call to a backend endpoint that handles calling ChallengeAsync or whatever

that would then redirect to my auth provider?

[queen needle]

Personally I always implement auth horribly

[sharp geyser]

I also do so

[queen needle]

So valid

[sharp geyser]

but for a project at this scale I really have to fucking try hard

😭

Money involved = security needs to be TIGHT

[pearl trail]

i stopped understand after reading ChallengeAsync, as i havent used aspnet that hardcore

[sharp geyser]

Well

Theres like 40 fucking ways to log someone in with Identity

ChallengeAsync is one of em

[cinder lily]

cuz ur always developing with a hacky version of localhost 👀

[sharp geyser]

Dang

shots fired

[queen needle]

It's because me and him are working on a project where he does the backend, but he hosts on a url and frontend is localhost rn so we had to do it a really hacky way to get it working

[sharp geyser]

Lmao

[cinder lily]

just develop on prod and the cookie issues go away

[pearl trail]

cors?

[queen needle]

Idk if it's any help, but the way I did auth on one of my recent projects with a separate backend, the server had a cookie that was shared, and I had a middleware which checked said cookie, and then I also had a auth provider with a "useAuth" hook

[sharp geyser]

Well, thats not really the case for me persay

[queen needle]

Which requested the user data and cached it and had a refreshUser function

[sharp geyser]

A cookie will be used

[queen needle]

Oops wrong reply my bad

[queen needle]

Well shucks

[sharp geyser]

Every day I get closer and closer to throwing my pc out the window

[queen needle]

So valid

[sharp geyser]

This project has been going on for a year and sadly we aren't even close to getting naything viably working

We've had so many bumps

[pearl trail]

nextjs is totally fine, i use it. but that may need a lot cpu + ram juice when it starts to gain a lot of visitors

[queen needle]

Don't forget Rome wasn't built in a year

[queen needle]

My strategy is just don't gain visitors, I should probably stop talking I'm not being helpful lmao

[sharp geyser]

Thanks discord, I requested my data and its empty 🙂

They gave me an empty zip file

[pearl trail]

💀

you sure it's not corrupted while downloading?

[sharp geyser]

Well it downloads fine

but extracting it wont because its "empty"

It says it has 9kb of data in it

[pearl trail]

💀

[queen needle]

Discord just magically stores no data for you

[deft wolf]

They sold it already

[sharp geyser]

Well shucks

I want my 9cents

Clicking the link actually does nothing

I have to click "Open in new tab" for it to download anything

[pearl trail]

oh yeah that might be a problem

[sharp geyser]

Opening the link in incognito downloads a 231mb file

Theres all my juicy data

anyways

I guess I will just figure it out

[harsh nova]

So far any with I've made have been decently solid afaik Passwords are always encrypted and all that

[queen needle]

My last full auth system I used supabase

[prime cliff]

Hmm thinking of a good way to have secure websocket server and client.

The server will be an asp.net app with an open port for incoming websocket connections.

The client will then connect to the server with a secret auth key that is hashed on the server so only that specific key and ip can connect and only the client knows it.

Maybe the client could also request some kind of session id to use or something.

This also means that clients can also be air gapped or firewall blocked on incoming connections without any issue.

The asp.net app (server) will be able to send websocket events to the client so it can manage docker containers on that client.

Currently using C# https://github.com/chronoxor/NetCoreServer

[pearl trail]

so client make requests to server via websocket?

i have yet see any site with that method

tho, that’s theoretically capable of doing requests, but ig it’ll inefficient(?)

[prime cliff]

Clients connects to the server so that the server can control the client basically.
Sort of like a device management system that enrolls.

Would make the client more secure and lightweight and the server itself only has the hashed version of the key that only the client knows but the server can verify and also better management of what ips can connect to the server too.

[pearl trail]

[humble gyro]

damn i didn't know netcore was chill like that

[sharp geyser]

you dont know a lot of things

but its okay

here we dont judge

we teach :3

[frosty gale]

for some reason we live in a world where some people have completely shifted away from the nature of having a web page almost be completely ready on page load to loading a js file which will then load the entire page (react)

[delicate zephyr]

SSR is a thing

people just forget

[pearl trail]

is there any difference between INT and INTEGER in sqlite?
❌ id INT PRIMARY KEY AUTOINCREMENT NOT NULL
✅ id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL
error is [SQLITE_ERROR] SQL error or missing database (AUTOINCREMENT is only allowed on an INTEGER PRIMARY KEY)

[harsh nova]

I don't think INT actually is a data type in SQLite

[delicate zephyr]

it's not

[frosty gale]

i am aware but a significant amount of pages still roll with client side only react

its also reduced load on the server so thats a nice thing about it

i think discord might be one of them

but then they do have a desktop client with electron so its reasonable

and its not the app that actually needs good SEO

[lyric mountain]

funnily enough, there is if we're talking about primary keys

if you define INTEGER PRIMARY KEY it'll replace implicit id_seq column

but if you INT PRIMARY KEY it'll keep the other

and well, autoincrement is finicky

[pearl trail]

[pearl trail]

ah, so it's something internal

[lyric mountain]

yep, sqlite has a lot of weird rules

for example you should not make an autoincrement pk unless you have a very specific need for it

since all tables inherently have id_seq

[pearl trail]

oh

[delicate zephyr]

yea cause you can use CURRENT_ROW or some shit right

cant remember the exact expression

Either way autoincrement is normally advised against

[pearl trail]

so i should make id (pk) either varchar or int and generate them by ourselves?

[pearl trail]

i see

[wheat mesa]

It really depends on your use case. 99% of the time SSR is overkill. If you have a client app that is somewhat complex, SSR might be a better option, but there is trade offs to consider. Working with SSR can suck for numerous reasons (such as timezones, I have personal experience in this hellhole), and it also costs the host more. If you are building a startup or even just an app that you don’t want to pay for hosting for, SPAs are the better way to go. They get you 90% of the same functionality for a lot less of a hassle

[quartz kindle]

the problem with SPA is that its a hellhole for SEO

each thing has its own hellhole xD

static html > *

[wheat mesa]

SPAs aren’t bad for SEO anymore

Google and the major web crawlers support most SPAs

[delicate zephyr]

can confirm this is no longer an issue tbh

[quartz kindle]

if you build it with some framework that does all the heavy lifting yeah

[lyric mountain]

you can also use the id_seq as you'd with an id column

[delicate zephyr]

never thought of this actually

[pearl trail]

oh, so that’ll override the internal id_seq so i can use pk and auto increment together? or it’s still a bad practice and keep generating my own id?

[delicate zephyr]

I mean if you wanna be hella convoluted and need the creation order for some reason just encode a jwt or some other token that you can decode to get the sequence lol

use base64 if you have to lmao

[lyric mountain]

in sqlite specifically ur supposed to use the id_seq

[radiant kraken]

interesting

[pearl trail]

i use sqlite because it’s light and for my quick 2 hours project so i don’t know much about it. thank you guys for the explanation 🙏

[radiant kraken]

how

[quartz kindle]

sqlite internally has a rowid column as well

you can manually disable it for a table as long as you have a primary key

[radiant kraken]

rowid?

[quartz kindle]

By default, every row in SQLite has a special column, usually called the "rowid", that uniquely identifies that row within the table. However if the phrase "WITHOUT ROWID" is added to the end of a CREATE TABLE statement, then the special "rowid" column is omitted. There are sometimes space and performance advantages to omitting the rowid.

A WITHOUT ROWID table is a table that uses a Clustered Index as the primary key.

[radiant kraken]

huh weird

what about id_seq?

that one puzzles me

[quartz kindle]

never heard about id_seq

is it another name for rowid?

In an ordinary table, "INTEGER PRIMARY KEY" means that the column is an alias for the rowid.

[radiant kraken]

this

[pearl trail]

its for postgres i believe

[quartz kindle]

yeah thats rowid

[delicate zephyr]

ngl this is actually kinda smart

[quartz kindle]

yeah i guess

rowid is an sqlite specific thing

[prime cliff]

You overcomplicate timezones too much kek it's actually quite easy.
Get users timezone hour offset ( -1 or +3 ) then just adjust the dates for it 😉

[quartz kindle]

anyone that says this has never worked with a timezone-sensitive project

:^)

[delicate zephyr]

fact

[pearl trail]

@solemn latch

[wheat mesa]

That's not the issue, the issue comes with the fact that you have to then include the timezone info within each request you make to the backend

It's a PITA to integrate into an application that uses SSR but didn't account for this to begin with

Not to mention dealing with localizing input data that the user sends (e.g., should this date field be in the user's timezone or someone else's, or the server's?), then converting it back to show to the user based on their info

[prime cliff]

Even the bot devs are falling for these dumb scams kek

[wheat mesa]

[deft wolf]

You can search on top.gg, that's what this site is for

[empty quail]

thats the thing. there are no other bots that is similar to that one and the one that is up is not working so yea

[deft wolf]

In that case, this sounds like the perfect option to make your own bot. If there is no public bot like it, we won't create it

[frosty gale]

we get it star boy

i just use intl+date api in browsers and it all just falls into place

[empty quail]

do u have any tips on how to start.. i already have a bot created but i cant find a good tutorial vid that can help me code

[deft wolf]

Depends on the language/library you use

Most of the popular libraries rather have a "guide" that will lead you through the basics of creating a bot on discord but you have to learn the rest with the help of documentation and practice

[empty quail]

Thanks!

[quartz kindle]

go into inspect element and type wrap into styles to see what pops

In my JS jank adventures I've been on, my npm module to hot reload JS files recently added the ability to reload all class instances' methods of classes specially marked as reloadable. This is already quite jank and has some draw backs like you cannot reload the constructor/add missing properties that would come from the constructor. You also cannot make it so that deep class hierarchies can also be reloaded. Classes must directly extend a special class that makes the magic happen.

A co dev also found an incredibly cursed way of making it work.

class ThisCanReload extends sync.reloadClassMethods(() => ThisCanReload) {
  constructor() {}
  magic() { console.log("1"); }
}

The return value of a function can be a constructor function and extends has no complaints about it. In this case, the function returns the base ReloadableClass. The callback with the return value of the class is to get a reference to the class that's doing the extending to update stored instances' prototypes. Finally had an excuse to also make use of WeakRef so that the old class prototypes can get garbage collected. There was a challenge though and it's that you can't iterate over a WeakSet, so we opted for a regular Set and used this cool thing called a FinalizationRegistry that runs a callback when something gets garbage collected so we can clean up entries of the Set.

There's also a thing where it can "remember" variables you want it to with a key (scope locked to files for security). If you don't pass a key manually, it reads the source file calling the function to get the variable name. How it does it is kinda brilliant, but not always possible to extract the variable name. Useful for having Maps or Sets you add to you don't wanna rebuild or store elsewhere

What about my fish?

[earnest phoenix]

fish faster than snake

ez

[bitter granite]

but its a plushy

[solemn latch]

Put it on a plane, faster than snake

unless theres snakes on a plane

but that would never happen

[lament rock]

Time to import snakes from around the world

it is the year of the snake after all

@radiant kraken i recomend you give it a watch

[radiant kraken]

i don't have hbo max

[bitter granite]

Netflix VPN

[radiant kraken]

wdym?

[bitter granite]

Its geoblocked in indo, but you can use VPN to watch it from other country

[radiant kraken]

i dont have vpn

[bitter granite]

https://help.netflix.com/en/node/114701

netflix allow it

[bitter granite]

Bro there is alot of free vpn

[radiant kraken]

free vpn = scam

[bitter granite]

What about Opera, Google vpn, express vpn, nordvpn, surfshark vpn

they have free ver

[sharp elbow]

Free VPNs do exist, it’s just that you are paying with your data privacy instead of money

[earnest phoenix]

tbh https://protonvpn.com/

[frosty gale]

i wonder how vpns went from this mostly corporate, niche thing to access private networks remotely to a million dollar industry under the guise of "privacy"

This makes it harder for websites, advertisers, and even your internet service provider (ISP) to track where you are and what you do online.
i hate this argument because you are basically shifting the trust model from your ISP to your VPN, not like it matters anyways

[earnest phoenix]

nordvpn had probably the worst advertising campaign

spreading fake and unrelated information and unnecessarily trying to scare people off

probably the funniest one is when they advertise their encryption as "military-grade". it's just aes...

[sharp geyser]

Thats military grade encryption right there

[lyric mountain]

it's funny when products are sold as military-grade

that just means they're the cheapest shit on the market that somewhat works

[wheat mesa]

"Military grade" means overpaying for an inferior product

😉

[wheat escarp]

What to do if I cant open top.gg on my safari browser send me a dm if u can help

[delicate zephyr]

Whats even funnier

is because its a publically accessibly encryption method

its even less likely that the military use it

[earnest phoenix]

nah tbh it's used a lot

but it's not really something special

all https websites use it

Finaly found my tazer clip

We should duo sometimes

[neon leaf]

no

im not that good

perma silver 3 on office

me when dev channel

[bitter granite]

we have arround the same rank

[green kestrel]

who's excited for components v2?!

[neon leaf]

🧐

[green kestrel]

i mean look what you can do with it

[neon leaf]

wtf

[green kestrel]

https://deploy-preview-1381--dpp-dev.netlify.app/components.gif

i mean how cool is that

we still get embeds and stuff, but we also get this!

[limpid onyx]

What, it's so cool

[vocal knot]

ohhh

i need more info on that

[prime cliff]

Ah yes announcing who's ready for a secret experiment that only about 20-30 people know xD

[deft wolf]

https://tenor.com/bMTmaNE8fC3.gif

Now we have 10 more people knowing about it

[vocal knot]

LOL

[prime cliff]

This server has more than 10 people in it

[neon leaf]

lies

[deft wolf]

This channel is Tim's basement, it can't hold more than 10 people (don't ask how I know)

[green kestrel]

https://github.com/Lulalaby/discord-api-docs/blob/comp_v2/docs/interactions/Message_Components.md

[green kestrel]

really? only 30 people have access to a server to play with it, but we are all lib developers making sure the libs are ready for it

its far from secret 😄

https://deploy-preview-1381--dpp-dev.netlify.app/components_v2.html

this is the D++ example for it

[vocal knot]

so finally video support lol

[green kestrel]

yup!

[queen needle]

I saw these a while ago and was waiting for more updates so I assume if now they've gone to library developers that they're getting closer

oh wait I misread your message but most of mine still stands

[neon leaf]

lets say I have a stream of 9-byte messages that contain u8 (type) u16 (x) u16 (y) u8 (height) u8 (r) u8 (g) u8 (b), how would I trim them so that overlaying pixels dont get stored multiple times, currently its stored as a simple u8 array, where each message is appended

[wheat mesa]

Are you intending to overlap the pixels that come sequentially? As in, you receive a message for one rectangle, then the next message sends another rectangle, but you want to overlap that rectangle over part of the first one?

Or are you intending to have a specific ordering, e.g. intending to send layer data in the future

[neon leaf]

https://draw-together.rjansen.dev/

basically I dont want pixels in the same spot to take up memory

[wheat mesa]

Why not represent each pixel as an rgb value and just change it to the new value when they overlap? Too much data?

[neon leaf]

too many pixels

i mean

atp that may be the only performant solution

2d array of pixels with a predefined res

2.7MB to store 720p

6.2MB for 1080p

yeah okay this seems fine enough

[wheat mesa]

Yeah, trying to handle compression and such might be a pain in the ass just to save a few bytes

[quartz kindle]

you can check for overlaps and merge them no?

[neon leaf]

in my mind that sounds very cpu and memory intensive

[quartz kindle]

well

how about this

store xy as a 24bit int, which gives you 12 bits per dimension, or 4096x4096

and index them somewhere

so you can easily look it up if its occupied or not

[quartz kindle]

tbh the way it works right now its pretty fine, the only meaningful improvement i can think of is to chunk the ws messages

currently its quite laggy due to to many messages when you draw

you can set a timer to join messages together and send them in chunks every 100ms or so

or even better, every requestanimationframe

id make it like this: when drawing, add messages to array, every requestanimationframe send all messages in array in a single ws message and clear array

[neon leaf]

so a hashmap with x+y => pixel?

[quartz kindle]

yeah its an option

[neon leaf]

hmm

[quartz kindle]

you are not storing empty pixels right?

you want to store only actually drawn areas

[neon leaf]

well

im currently storing the entire history

[quartz kindle]

well, storing the entire history is also interesting since you can replay it later

you can keep it as a feature if you want

how do you make history_2.raw?

do you read the history on the server side every time before sending it? or do you have a snapshot you can send right away?

[neon leaf]

I read the in-memory history unless saving is enabled, then I read the history_2.raw file (since when the file is there but saving is disabled, the file only contains the start data)

[quartz kindle]

hmm, you can have two options then:
history enabled -> store both the message history and a pixel hashmap
history disabled -> store only a pixel hashmap

the hashmap is for both quickly loading the current state of the image, as well as for deduplicating pixels

the message history is only if you want it to be replayable later

[neon leaf]

hm hm

[quartz kindle]

and yeah, try chunking together websocket messages, it should drastically improve drawing performance

[neon leaf]

yeah, that shouldnt be too hard

[neon leaf]

do you think I should do this for every ws message or just periodically?

the problem is only 1 thread can access the data at once, and it blocks all other threads in the meanwhile

[quartz kindle]

you mean on the server side?

[neon leaf]

yes

[lyric mountain]

waddya doin?

[quartz kindle]

well, it shouldnt be a problem, with message chunking plus a hashmap is should be plenty of fast enough

with message chunking you wont get too spammed on the server side, and im pretty sure an int-key hashmap should be capable of millions of ops

tbh not a hashmap, something that doesnt hash is better

since your keys are ints

[neon leaf]

array

[quartz kindle]

sure

sparse array

or holey array

xD

you can also offload the data saving to another thread

so it doesnt block the server thread

[neon leaf]

well there is no server thread

I mean there is but nothing is on it

[quartz kindle]

i mean the websocket server

[neon leaf]

ye

each ws is a seperate thread

3 actually (+1)

[quartz kindle]

ah then its fine

wait why 3 lmao
