ah you're talking about voice channels
not possible to do via rest api
only via websocket voice events
sharp geyser
use the voiceStateUpdate event to see if they are in that channel
ifyou are using rest only sorry
like tim said not possible
proven lantern
dang
quartz kindle
you have to listen to voice state events and then store that information yourself
its the only way of knowing whether a user is in a voice or not
also
when you connect to the gateway
you do receive a list of all users connected to voice channels
so that you can have a state to start with
sharp geyser
you dont need to connect to the main gateway do ya?
since the voice gateway is separate
quartz kindle
no its on the main gateway

Honestly this will be virtually impossible to do effectively without the gateway
blindly deafening them is a bad idea as well
same with removing them
proven lantern
Honestly this will be virtually impossible to do effectively without the gateway
what if i give the other members MOVE_MEMBER permissions in the channel.
then they could remove them manually perhaps
or is MOVE_MEMBER not even a channel level perm
let me see
nope, not at the channel level
perhaps i give members this permission in the channels
if two users have this permission can they deafen each other?
or only if the other member doesn't have the permission
lament rock
if two users have this permission can they deafen each other?
Yes they can server deafen each other other and undeafen themselves
proven lantern
Yes they can server deafen each other other and undeafen themselves
so they could deafen the member that leaves the lobby, but they could also troll each other

@quartz kindle I have a question about memory
If applications use memory, and they typically use a certain amount, and if you have multiple applications open, how does another application know an address is taken by a currently running application and not to touch it?
Is it some sort of like "This is strictly reserved, you better not touch it" and if so, how does it communicate that
Idk if this is an appropriate question to be asking right now or if ima confuse myself, but I was curious
quartz kindle
If applications use memory, and they typically use a certain amount, and if you ...
the OS is in charge of managing that
sharp geyser
Hm I see
quartz kindle
i dont know the details, but the OS allocates blocks of memory and assignes a process id to them
the program itself does not know anything about memory besides what the OS tells it
sharp geyser
Ah I see okay
That makes sense
I thought the program itself was handling the memory
but that makes more sense the OS allocates it for it
quartz kindle
what the program sees is "virtual memory", which basically means the memory that the program thinks its using
virtual memory is an arbitrary number that often doesnt make much sense
some times the program has a virtual memory of several times more than the amount of ram
sharp geyser
👀
quartz kindle
thats what the program thinks its available for use
sharp geyser
Thats kind of crazy
quartz kindle
when the program actually wants to use it, the OS will manage that, check if its available, howmuch is available, put parts in ram, parts in swap if needed, take away unused ram from other apps, etc
sharp geyser
oh thats cool
So thats why you see applications sometimes go from using more ram to using less
quartz kindle
the OS also makes a lot of memory "mapping", for example the app wants 50mb, the os gives it a block of 50 mb, from address X until address Y
but the OS then maps this to random places that the app doesnt know about
for example addresses from X until X+5000 will be in X location in ram, then from X+5000 until X+10000 will be in another location in ram, then the rest in swap
the actual physical location of data in ram can be anywhere, can be fragmented, split in pieces and other stuff
but the app will never know about that, it only sees a block of ram
when you try to access parts of memory you shouldnt, in low level languages two different scenarios can happen (correct me if im wrong about this tho)
either the invalid area you access is still inside the physical locations of memory that belong to the same app, you get random garbage data or undefined behavior
if it happens to be outside of the physical locations that belong to the app, then you get a hard failure, access violation errors, segfault, etc
sharp geyser
sounds correct
I know until you give a definition a value it will hold garbage data
if you do
int main(void)
{
int n;
printf("%i\n", n);
}
it will have garbage data
quartz kindle
any memory allocation will hold garbage data by default, because it would be expensive to constantly write zeros whenever areas of memory are freed
sharp geyser
yea
quartz kindle
so it only writes zeroes when explicitly requested
quartz kindle
ye
sharp geyser
iirc if you try to write something out of bounds of your allocated memory, it will segfault tho
at least in C (from what I saw)
quartz kindle
ye
sharp geyser
it doesn't even return garbage data, it just segfaults
quartz kindle
how memory is allocated is a whole other field of study, actually, and much of it is still being developed today
quartz kindle
you have a bunch of new-ish allocators out there, like mimalloc, jemalloc, tcmalloc
with different tweaks and strategies to read/write to ram faster
but its a very complex field
quartz kindle
because fragmentation is a big problem
the gist of the issue is basically like this
if you have an array of size 10, and indexes 1-6 are used by one program, then 7-10 are used by a different program
then you close program 1, and free indexed 1-6
then start a new program that requires 7 spaces
you have 1-6 free, but its not big enough to write 7
sharp geyser
so you need to fragment it?
Where it takes up those 1-6 spaces so its not wasting memory
but then it takes up 1 space in another?
quartz kindle
so you either make the array bigger and write 11-18, and leave that 1-6 unused, making the program use more memory than it should
or you fragment it, and make it slower
yeah
sharp geyser
so fragmenting is slower
whch makes sense
because now it has 2 blocks to read/write from
quartz kindle
now repeat this process over thousands and millions of times as computers open and close processes
and you have a real chaos in your ram
sharp geyser
is fragmenting how its normally done rn?
quartz kindle
most allocators allocate in fixed blocks
for example even if the program needs only 90 bytes, it will alocate a block of 256 for example
but then the allocator has multiuple block sizes
sharp geyser
For what reason
quartz kindle
called "arenas"
sharp geyser
that seems like a waste of memory
quartz kindle
so if a program needs 900 bytes, instead of multiple 256 blocks, it will use one larger 1024 block
a different arena
and then plays around with these different block sizes, like a puzzle
like tetris
although fixed size blocks are less memory efficient, the performance advantages are very important
sharp geyser
Right ima put a stop in that for now
I think my brain might explode if I take any more information in
lyric mountain
Byte alignment is a big deal
quartz kindle
for example if you didnt have fixed predictable block sizes, whenever you write and delete, a large part of time would be spent trying to calculate how big are the holes left between blocks and how to fill them efficiently
which would lead to worse performance and much worse fragmentation

i have no idea how the pipe works in rust
proven lantern
the pipe character
sharp geyser
thats just how you do lambdas
proven lantern
// scope
}```yea thats a lambda buddy
all {} does is make it allow you to do multi line
the stuff between the || is the properties the function returns
and you are able to do stuff with it
sharp geyser
ofc
{} is how you scope things
fn main() {
let a: i32 = 2;
{
let b: i32 = 3;
println!("{a}");
}
println!("{b}")
}
I do not like the mockery
civic scroll
the stuff between the `||` is the properties the function returns
isn't that function parameters
sharp geyser
what
civic scroll
but that would just output ` { Hello world! }`
that outputs the full tree, as expected
since {} denotes JS expression within JSX element
sharp geyser
its the stuff from the previous function
sharp geyser
the parameters is the data from the last function
let command_name = body_parsed.get("data")
.and_then(|data| data.as_object())
.and_then(|data_map| data_map.get("name")
.or_else(|| data_map.get("custom_id"))

just tell me that's a callback
i'm from js land
sharp geyser
I mean
civic scroll
sharp geyser
what is your definition of a callback
civic scroll
like js callback, gets called after the operation is complete
sharp geyser
because you can do something like
Box::pin(async || {})
eg.
.then
sharp geyser
I wouldnt necessarily call that a callback
civic scroll
in the Future case
sharp geyser
If you are working with future sure
sharp geyser
but in general a lambda is just a function inside of a function
usually you'd return something inside them as well
sharp geyser
I mean truthfully thats what lambdas are
ask @radiant kraken
all a lambda is just a fn inside a fn that returns something
sharp geyser
No idea
radiant kraken
@civic scroll what is it
sharp geyser
we were discussing lambdas
sharp geyser
no, but usually you find them being used as such
radiant kraken
some languages like python and javascript lets you define lambdas top-level
sharp geyser
we are talkin bout rust
civic scroll
2.as_pipe()
| append(3, 4, 5)
| reverse
| add(3)
| product;
then sure you can only define lambdas inside functions
sharp geyser
Ive yet to see a lambda in rust not be defined in a fn
radiant kraken
or use a function pointer for functions that accept lambdas as parameters
civic scroll
Ive yet to see a lambda in rust not be defined in a fn
a lambda outside fn is just a fn

it's just that you can't do dn inside fn so you use lambda

Also, is there a Next.js guide that I may as a beginner to web development?
But uh, without HTML and CSS knowledge it seems to be impossible
And I should also learn routing as well
sharp geyser
This is where I start to get a little harsh.
I 100% do not recommend whatso ever using a framework before actually knowing html and some css
Using a framework without such knowledge will leave you clueless.
You will be forced to not only
- Learn HTML
- Learn the framework itself & CSS (if you want to do so)
It's better to focus on one, then do the other.
HTML is something that can quite literally take you a week or two to learn.
Of which you can do while workin on your bot.
You yourself said its not urgent to have a dashboard, so take your time and don't overwork yourself and take on more than you can handle.
CSS is something you can learn as you use the framework though, so I am mainly just saying learn html
neon flicker
Ah thank you so much

its for video/audio transport for live streams
No
well sure

sharp geyser
the official team behind srtp calls it srt
so I dont want to hear it

have you ever looked at or used it

you have TCP with TLS
its UDP
sharp geyser
RTMP is a TCP-based protocol which maintains persistent connections and allows low-latency communication.
SRT is UDP tho
quartz kindle
ye
RTP typically runs over User Datagram Protocol (UDP). RTP is used in conjunction with the RTP Control Protocol (RTCP). While RTP carries the media streams (e.g., audio and video), RTCP is used to monitor transmission statistics and quality of service (QoS) and aids synchronization of multiple streams.
sharp geyser
there is also RIST, ARQ, Zixi
SRT seems like the most likely one to use tho
im just trying to wrap my head around it

All the services that offer live streaming capabilities with protocols like SRT are like 40$ a month for shit features
some even 200$
Absolutely bogus
sharp geyser
Wtf
quartz kindle
also, my bad,you were right

apparently browsers dont support it yet tho

SRT is supported in the free software multimedia frameworks GStreamer, FFmpeg, OBS Studio and in VLC free software media player
In March 2020, an individual Internet-Draft, draft-sharabayko-mops-srt,[1] was submitted for consideration to the Media OPerationS (MOPS) working group of the Internet Engineering Task Force.

yeah a lot of error checking and bouncing back and fourth
that has a devestating impact on performance
also not to mention UDP can basically also send some packets in parallel since it does no error checking
it can route packets across different network paths at the same time and when they arrive at the destination they will be reordered
quartz kindle
yeah its unordered so in case of failure it doesnt need to wait for the queue to resolve
its like a shotgun, fires multiple packets for multiple streams and connections at once

but like, it's been working fine
what would cause this error back to back suddenly?
it's even working fine right now, but another server was trying to play it and it keeps giving this error
quartz kindle
the issue is around here
what stands out there are database calls
try to measure the performance of those database calls to see if any of them is taking too long to run
for example ```js
const now = performance.now();
db.prepare(...)...
console.log("db call took", performance.now() - now);
okay let me see
quartz kindle
measure both the SELECT and the UPDATE calls

ok let me try this
@quartz kindle I know you're pretty good with optimizing... any suggestions with this game?

100ms is a long time
can you check which of them is taking 100ms? the update or the select one?
also, can you show your db.js?
past field
can you check which of them is taking 100ms? the update or the select one?
yes let me add the logging and see
quartz kindle
add this: ```js
db.pragma('journal_mode = WAL');
anywhere in the file, as long as its after new Database and before module.exports
past field
add this: ```js
db.pragma('journal_mode = WAL');
```
what does this do
quartz kindle
what does this do
enables WAL mode (write ahead logging)
WAL mode allows the db to not need to wait for an update to be completed before the program continues
it writes the update instantly to a separate file, and then merges the updates in batches later on
quartz kindle
yeah

ok added

quartz kindle
looks much better, everything is under 1ms
past field
would that have caused an unknown interaction error?
quartz kindle
not directly, but the unknown interaction error happens when you take too long to respond
discord only gives you 3 seconds
and those 3 seconds do not account for the time it takes for the event to travel until your pc and be executed by your code
so when responding to interactions, performance is very important
quartz kindle
imagine it takes 1 second from discord to your pc, then another 1 second from your pc to discord
then would mean your code only has 1 second left to use
sometimes when the internet is slow or congestioned, 100ms from a slow db call can make it or break it
but most times a healthy internet connection wont take more than 200-300 ms for a full round trip, so realistically your code should have around 2.5 seconds of processing time, most times
but even the fastest code will run at that error every now and then, because when the internet really craps itself and the event takes more than 3 seconds just to reach your pc, theres literally nothing you can do about it
past field
ahh ok i see what you're saying
sharp geyser
and those 3 seconds do not account for the time it takes for the event to travel...
even if you deferReply?
quartz kindle
even if you deferReply?
deferReply comes between the arrival of the event and your code
so if your code is slow, defer will save it
if the arrival is slow, it wont make any difference
sharp geyser
fair enough
my rule of thumb is to always deferReply if I am doing anything that takes longer to process
like db calls
quartz kindle
ye
sharp geyser
cuz db calls while fast, never know what might happen and it takes longer than usual
deferReply saves you a bit there
I think it gives you an extra 10s right?
quartz kindle
but with sqlite its not really needed, because sqlite (better-sqlite3 specifically) is not actually async, and its as fast as any other sync code (avg 0.1ms )
but yeah it depends on how you use it, inefficient queries can make it very slow
quartz kindle
I think it gives you an extra 10s right?
15 minutes
quartz kindle
ye
sharp geyser
Didn't think it was that long
quartz kindle
thats the maximum validity of an interaction token
sharp geyser
deft wolf
15 minutes?!?!?!
quartz kindle
does my set up look ok tho lol
as long as the db calls are fast its fine to keep it as is
fast meaning less than 5ms

hey guys, i come from a more functional background like haskell and java, are we allowed to use wildcards in js such as above usecase?in reality, i can just do default i think, but i guess i always wanted to know this \0/
neon flicker
In order to use Next.js, what I need to know is JavaScript, HTML & CSS, the framework itself and React.js, right?
I think I started getting with HTML, however I have zero React.js experience
solemn latch
Nextjs is somewhat different, you don't really need to learn react first before nextjs.
neon flicker
So it would work to learn Nextjs itself right?
solemn latch
Yeah.
But I'd make some basic html/css pages first just to understand the basics of it.
Like figure out what your home page will look like with just raw html and css.
Then once you feel a bit comfortable you can start to learn nextjs.
Nextjs has a tutorial that's probably pretty good(its been rewritten since I learned)
https://nextjs.org/learn
Just remember its not a race to learn these things.
No matter what it will be frustrating and hard.
Even if you only use html css and js.
neon flicker
I really appreciate all the help you've provided me, it will prevent me from hesitating before asking questions in the future
sharp geyser
quartz kindle
```js
prices.map((x) => {
switch (x) {
case "Bieden":
return ...
case default
sharp geyser
default is the wildcard
if all the others fail it goes there
it handles the default case
quartz kindle
you can however use switch(true) if you want more advanced cases
sharp geyser
👀
interesting
then you'd be using conditionals as the case statements
honestly never thought of that
💀
quartz kindle
ye
it kinda defeats teh purpose of using switch in the first place, but its there as an organizational option
like a glorified if else
frosty gale
for reverse proxy you always use http1 on the node side
yeah i realised that, although its a bit inefficient
sharp geyser
true

nginx has to do additional processing instead of being able to sort of pass the request through
and parsing of http 1.1 which is slower
sharp geyser
honestly I need to learn how to use nginx better
cuz I swear most of my problems come from nginx
😭
quartz kindle
nginx has to do additional processing instead of being able to sort of pass the ...
yeah but if you want full passthrough, then node would need to handle ssl, and it will probably be much slwoer that way
frosty gale
actually yeah ssl probably gets rid of any performance benefits youd get with http 2
darn encryption
quartz kindle
not only gets rid of them, it sends them into negatives :^)
frosty gale
nginx still has to manhandle the request
solemn latch
honestly I need to learn how to use nginx better
nginx subrequests ❤️
quartz kindle
nginx still has to manhandle the request
btw Angie supports http3 to upstream
(nginx fork)
frosty gale
ive heard about http3 but i heard a large portion of services still havent migrated to http2 so theres not much point supporting
so dont know what it is
is it quic?
quartz kindle
is it quic?
http over quic, yes
neon flicker
React.js is what we use for routing right?
earnest phoenix

neon flicker
Oh
solemn latch
I've never used react itself, so I'm not entirely sure
frosty gale
I've never used react itself, so I'm not entirely sure
probably for the best
solemn latch
With all the recent drama with react... probably
At least they're working on a compromise.
lyric mountain
I hate react partly due to how messy it can get at the hands of someone who doesn't care
frosty gale
http over quic, yes
i have a feeling were going to see the end of TCP
since http 3 is based on udp
they may redesign it on the network layer
frosty gale
(nginx fork)
why did they fork nginx anyways
quartz kindle
i have a feeling were going to see the end of TCP
it has the potential to replace tcp in most cases yeah
you mostly only use tcp if you need all packets to always be in order
quartz kindle
why did they fork nginx anyways
angie was forked by russian nginx developers who were fired for being russian

`case default`
i see
is there an equivalent for function compositions in js?
I loved the haskell $ operator
it was actually a precendence operator, but it allowed you to do:
f $ g x instead of f(g(x) )
quartz kindle
it was actually a precendence operator, but it allowed you to do:
f $ g x instea...
there is function composition in js yes, but there isnt any specific operator for it
frosty gale
angie was forked by russian nginx developers who were fired for being russian
ive heard that nginx also has a paid version so they want to keep some good features behind their enterprise paywall which some open source devs dont agree with
quartz kindle
ive heard that nginx also has a paid version so they want to keep some good feat...
yeah some of its features were made free in Angie
as well as in Tengine, the chinese alibaba nginx fork
quartz kindle
Tengine has been maintained since 2011 apparently
and they hardcoded many nginx modules for performance
and use a modified ssl lib
sharp geyser
React.js is what we use for routing right?
Nextjs has its routing built on top of react's app router
It just allows you to do dynamic routing with like slugs and nested routing much easier
propose you have something like this kind of layout
src
--app
---[user_id]
----index.jsx
---index.jsx
nextjs automatically routes that as
example.com/
example.com/user_id/
quartz kindle
i might replace nginx with angie then
i might give it a try as well
sharp geyser
[user_id] is a folder btw
sharp geyser
its important to note teh [] that denotes it as a "slug"
frosty gale
2 months last commit and project was started around 2 years ago
im not certain about future updates and maintenance
sharp geyser
you can even do something like
neon flicker
nextjs automatically routes that as
example.com/
example.com/user_id/
So it makes it a lot easier, like I don't need to script it for every single route and just make the folder like this?
sharp geyser
src
--app
---[user_id]
----settings
-----index.jsx
----index.jsx
---index.jsx
settings being another folder
folder names get turned into route names
sharp geyser
So it makes it a lot easier, like I don't need to script it for every single rou...
It does it automatically for ya
indeed
Now, you can use the page routing which is slightly different (not recommended)
solemn latch
The app router is so much more pleasant to use 😄
sharp geyser
the App Router is the new standard in nextjs, they offer support for both as of right now to prevent a breaking change (backwards compatability)
Eventually they will require you to use only the app router afaik
A lot of sites still use the page router
solemn latch
I'd bet most do.
sharp geyser
If they were to outright remove it those sites would break
neon flicker
.jxs is used for XML, which is a programming language as well right?
neon flicker
It does it automatically for ya
Thanks 😊
solemn latch
I just think of jsx as javascript and html combined.
sharp geyser
`.jxs` is used for XML, which is a programming language as well right?
jsx is not XML
neon flicker
So it's pretty much nothing new right?
sharp geyser
Not really
solemn latch
a few syntax changes
sharp geyser
Only thing to note is
you can use {} to embed js into the html
and the result of that js will be displayed in the end
for example
function Home() {
const todo = ['Make Apple Pie', 'Do the dishes', 'Clean the yard'];
return (
<>
<ui>
{ ...todo.map((t) => <li>t</li>) }
</ui>
</>
)
}
module.exports = Home;
I think thats how that works I have not used js in a while
But thats the rough idea
neon flicker
So it's pretty much what I would use for like component reactions (such as button click) and etc in case I would need to use JS modules
sharp geyser
pretty much
JSX gets rid of the need of having
.html files and .js files
it combines it all into one
its a react specific thing
or at least, react uses it the most
neon flicker
Oh, and it's also used by Nextjs right?
sharp geyser
Indeed
Nextjs is built ontop of react
its a framework for a framework so to speak
:p
It just adds neat functionality to react that saves time from implementing it yourself
neon flicker
Wow, it made everything more clear for me
Thank you a lot again, I really appreciate it much
sharp geyser
Not a problem!
sharp geyser
Idk man
you might need to tweak it some more /j

you got to be out of your damn mind
At that point save up another 300 and buy a decent pc
Sony is already porting some of their exclusives to pc anyway
xbox been had it because windows

lyric mountain
Sony is already porting some of their exclusives to pc anyway
and failing miserably at that
everything would work fine if they didn't insist to force psn account
sharp geyser
I mean, its fair
All your PSN account is just a sony account
Ubisoft requires an account to play their games
no one complains
lyric mountain
ubisoft isn't blocked in a ton of countries like psn
earnest phoenix
no one complains
primary reason people complained was because some people couldnt access psn
lyric mountain
also sony is infamous for having data as secure as a wet cardboard
sharp geyser
usually Ubisoft is the one that shit like that happens to
sharp geyser
also sony is infamous for having data as secure as a wet cardboard
To be fair its wet cardboard with a small volt of electricity running through it :D
More annoying than secure
lyric mountain
we literally had to shove sony away from helldivers so they didn't reduce their playercount by 50%
sharp geyser
💀
Didn't helldivers have an issue where not everyone could play it?
Like people spent 60+ on it and turns out they couldnt even play it
lyric mountain
psn integration wasn't working properly at release, so they made it optional
sharp geyser
lyric mountain
but then sony demanded that it became required, so people who bought the game couldn't play anymore cuz they couldn't make an account
sharp geyser
I mean usually studios behind games for playstation is not the worst
I mean Ghost of Tsushima was amazing
lyric mountain
then the refund wave was so big that steam removed the game from store until it was resolved
the game went from overwhelmingly positive to overwhelmingly negative in less than a week
sharp geyser
Is it sony blocking the countries or the countries blocking sony?
lyric mountain
iirc it's sony that's choosing what countries they want to support
lyric mountain
probably currency value reasons
sharp geyser
Like just support the countries you aren't being blocked in
lyric mountain
but then sony nuked their playerbase, so idk if it's about money
sharp geyser
probably currency value reasons
I can almost guarantee you the money they "lose" in those areas with lower currency value is mute to what they make everywhere else
probably not even 1%
eternal osprey
you might need to tweak it some more /j

should i have 1 database for all purposes or different databases for specific purposes?
eternal osprey
usually 1 database is enough as long as you have multiple tables and link them together.
i would use multiple databases if you have distinct distinct features that don't have any correlation, parting it would not be needed but in reality it would be safer
past field
i gotcha
so i created a game with its own currency and that database keeps track of games played, games won, currency, basically game data

Hey guys Ik youve already heard this a lot but I wanna know how do big bots scale ?
I’m sure they not using something like djs right
Do I need to use discord api to like register ws? And scale? How do I shard
And stuff
digital swan
idk the specifics but im sure they all use their own sort of library
sharp geyser
I’m sure they not using something like djs right
So not every js bot uses djs you are right.
Some of them use their own version of djs or make their own library
I'd say using djs is fine up until big bot sharding
That's when I suggest looking to other avenues whether that be making your own library, or even porting over to a more memory efficient language that has a smaller footprint

When it comes to the term bandwidth in streaming videos (VOD specifically) how exactly is it impacted? I really hope its not entirely based on the size of the video being streamed e.g if a video is 50gb then it takes 50gb of bandwidth to stream it.
pearl trail
afaik unless the system change the quality (lower bitrate, lower resolution), it'll stream it 50gb, like plex instance

How to add a message a timed component listener?
👀 what are you trying to do?
neon flicker
👀 what are you trying to do?
Well, when the bot sends a message with a button component, I want it to seek for any interactions for a certain amount of time
Sorry if I couldn't express it well

In discord.js it's called collectors
solemn latch
For some reason I thought it was a nextjs question 😄
neon flicker
Aw sorry yes

Ah, I'm learning HTML yet 😄
Tho I think I started getting with it
I found the documentation about collectors thanks

I found the documentation about collectors thanks
also look into the awaitMessageComponent methods, better than collectors for 1 use

Which permission is necessary for _chnuke(channel nuke)
MANAGE_MESSAGES gives you access to bulk delete and regular delete.
Special note on bulk delete: You cannot bulk delete messages older than 2 weeks

MANAGE_MESSAGES gives you access to bulk delete and regular delete.
Special note...
Like
Deleting channel
And making channel in same position
At same time
Which permission is required for that
lament rock
MANAGE_CHANNELS and MANAGE_PERMISSIONS
lament rock
So you can add permissions to the channel…?
solemn latch
When creating a channel you can set any permissions, its not technically needed iirc
earnest phoenix
No
It's not feature
That editing permission of channel
It just creates not edits
lament rock
If the channel has any special permissions or overrides, it might be desirable to put them back
no?
quartz kindle
if the channel you delete has special permissions, the new channel will not have them

No

No

quartz kindle
No
earnest phoenix
Which permissions should i use?
solemn latch
ie, if someone would do nuke on our moderators channel, if it was deleted and created without new permissions everyone could see the new mod channel 👀
If your intention is to recreate the channel you do need to set permissions.
But, when creating the channel afaik you can set any permissions without manage permissions.
quartz kindle
menage a chanel
earnest phoenix
I don't want
That permission should be change
It would be default
Like when we create new channel
None of changes
Then only managechannels required?
quartz kindle
yes
lament rock
I personally wouldn't use any bot that doesn't offer that feature, but if it's for personal use only then what do I care
solemn latch
yes

@quartz kindle thought youd find this interesting https://lyra.horse/blog/2024/05/exploiting-v8-at-openecsc/
do note the function theyre exploiting isnt real, its just a prototype function made for a CTF to show how you can potentially break out of the V8 engine and do RCE with vulnerable v8 code
i dont understand most of it since i dont thoroughly understand v8 and that would take too much time anyways but its pretty interesting
no wonder it takes ages to get a single patch into the V8 engine
a single mess up could mean RCE in millions of browsers just by running some js

pretty impressive
interesting to see how unbreakable js looks like from the surface, but how under the hood its hanging on a thread of carefully written cpp validations
