anyone know if javascript has a function for comparing two strings with resistance to timing attacks?

ill probably need to use a library for this but would be nice if crypto had it built in

wanted to tag voltrex but of course hes banned

at this point theyre banning anyone remotely useful and competent

[lyric mountain]

there's still tim

[frosty gale]

@quartz kindle any ideas?

[lyric mountain]

but well, if both sides are hashes, how would a timing attack work?

[frosty gale]

id of course use a password hashing and comparing library for this usually but in this case i dont need anything hashing just some simple resistance to timing attacks

[harsh nova]

We do not ban people for being competent

[lyric mountain]

I'm still green regarding hacker attacks and exploits

[frosty gale]

theyre not hashes in this case

but i think hashes are pretty good when it comes to timing attack resistance

[lyric mountain]

ok so lemme rephrase: why are those passwords not hashed?

[frosty gale]

its too simple and i need to be able to change the passwords via a config file quickly

dont worry this is not production work

i think you can make your own timing resistant compare function with some random iterations and delays but i think someone sophisticated enough can filter through that with statistics

[quartz kindle]

why is voltrex banned lol

[lyric mountain]

well, couldn't you add a random ms delay at one of the steps?

[frosty gale]

god knows

[lyric mountain]

this would give fake info to the attacker

[harsh nova]

Silly question but why are you worrying about timing attacks if it ain't prod anyhow? Genuine question as I'm dumb not tryin to question the decision itself

[lyric mountain]

from what I know, something happened that made him burst and do or say something offensive

but that's as deep as my knowledge about it goes

nobody went into details when I asked

[frosty gale]

because it might be public at some point to a closed source of people and i dont want them breaching my passwords lol

better to be safe

[quartz kindle]

afaik js itself is invulnerable to timing attacks

[frosty gale]

actually i think you can use hashes by hashing both the password and user provided password then comparing them

timing attack gone?

[quartz kindle]

because the language itself is so random in terms of execution speed ]

[harsh nova]

Gotcha, thanks! Sounds solid

[frosty gale]

yeah thats what i thought initially

[lyric mountain]

simply jsfuck the sensitive parts

virtually nobody would attempt to translate it

or optionally, defer the comparison task to a separate api

[frosty gale]

its not the end of the world if it gets breached anyways

i think for added safety ill hash both passwords with sha1 then compare them

or i could always hash and salt the passwords on boot for all accounts in memory

sorry i believe sha1 is close to being not recommended for cryptography so# sha256 then

tim always comes through

i dont see anything about it online so it must be new

ah node v21

my node is 3 generations out of date to use this

[lyric mountain]

js ecosystem is so volatile that 300 libraries die are born every second

[frosty gale]

insecure hashing algorithm

iha

let the rename process begin for sha1

[sage bobcat]

[frosty gale]

yeah its available for the latest node, how convenient

thanks

[quartz kindle]

huh

it says it was added in node 6.6.0

[frosty gale]

oh fuck i was looking at the wrong thing

splendid

but as a side note its scary how many developers are unaware of timing attacks

but it just happens most crypto libraries handle that for you so they dont need to worry

[surreal sage]

OKAY

WHAT?

i have

never seen this before

[lyric mountain]

nested too deep in folders

there's a hard limit for file paths

[lament rock]

using numerical indexes, I have to update all tracks after an index because the order gets fragmented. Going back to front like a linked list guarantees order albeit with it being O(n) to sort as each entry needs to find which other entry links to it. Plus you only need at max 2 updates for order

How much code currently goes:

const orderedTracks = []
let last = entries.find(i => i.next === null)
if (last) orderedTracks.push(last)
while (last) {
   last = entries.find(i => i.next = last.video_id)
   if (last) orderedTracks.shift(last);
}

My thing is that I need to reorder the tracks at any time to any index with minimal updates. My current solution suffers from needing all tracks in the code to sort and it being O(n)

[sharp geyser]

🤔

you can probably do some sql magic with the use of the ORDER keyword and update

[quartz kindle]

^this tbh

[quartz kindle]

linked lists are good, but if you're gonna be making database calls for every single link in the list thats probably gonna be terrible

option 1: store everything you need for the ordering in columns, use sql's own ordering functions when retrieving
option 2: store everything you need for ordering in a single row so that updating and reordering only takes 1 round trip to the db

[lament rock]

It isnt like that. It's just fetch all entries in batch then sort with the code I mentioned. I'd like the db to sort the list, but I can't write sql statements that complex. Reordering already only takes at max 2 update calls

[quartz kindle]

whats the sorting criteria?

[lament rock]

The user can have their own order of the songs, so #1-length. Can return sections for pages

There is a mv command

[quartz kindle]

if the user defines the order, you can for example have a position column on the db, where each entry has a position number, when fetching you can do SELECT * FROM table WHERE id = X ORDER BY position

when updating, you dont necessarily need to update all entries, you can for example start creating intermediate numbers when needed

[lament rock]

oh?

[quartz kindle]

like you want to move position 6 to between position 2 and 3, you can set its position to like 2.5 or something

[lament rock]

I hate that idea lmao

[quartz kindle]

lmao

[lament rock]

I thought about just using another storage medium but lmao

err I guess I can also do something like this for updating:
UPDATE playlist_songs SET order = order + 1 WHERE order > ${index_moved_to} AND order < ${index_moved_from} for if index_moved_to is less than index_moved_from

Just one update operation

can easily flip the operators

I'm struggling with math mentally though for other cases I don't wanna deal with :(

[quartz kindle]

xD

but yeah, the more work you let the db do for you, the better, usually

[summer dust]

How does Discord limit the size of attachments for bots?

[deft wolf]

This is the same limit as users

[thorny cargo]

Wdym, how many images can it post at once, or how many times per second . Explain please

[deft wolf]

Unless the server allows more

[summer dust]

idk You can try for() to figure it out.

[thorny cargo]

Whats ur question here

[summer dust]

send video and audio file and how does discord limit size

[thorny cargo]

But anyways the limit should be 10 attachments if I aint wrong

[thorny cargo]

8mb might be it

Not sure

[deft wolf]

Now it's probably 24mb

[thorny cargo]

Maybe yeah idk

[deft wolf]

But this is the same limit as the limit of a regular user without nitro

[thorny cargo]

Then that should be it

[summer dust]

i tried send a video size more than 24mb and and got this error

[deft wolf]

Then read what this error means

It's probably not strictly related to Discord

[thorny cargo]

Would be helpful to show ur code

[lapis siren]

Some people do. The explanation provided on the post applies.

[deft wolf]

https://stackoverflow.com/a/71505942

Here you can find an explanation of what this error means and how to "get rid of it"

[thorny cargo]

Can u please show us ur code

[deft wolf]

This has nothing to do with the code really

[summer dust]

ohh i see if i send video file under 20 mb video will send without error if more than 20mb will got error

[thorny cargo]

U never know, js tricky

[deft wolf]

If you have a poor internet connection, this error will still occur

[thorny cargo]

Well u found the issue

[thorny cargo]

And

[thorny cargo]

Its probably 24mb as nynu said before

[thorny cargo]

I would suggest to maybe write a function to check if a file size is more than 24mb , to compress it , would be cool

[pale vessel]

try sending a normal message with that attachment instead of a webhook?

[lapis siren]

Weirdly enough, it's not a 413 they got, but a 500.

Nothing to do with file size, just an internet connection issue.

[thorny cargo]

Can u followUp without defering ?

[summer dust]

i'm trying sending video quality === 2 with no audio

[thorny cargo]

Thats off topic but anyways

[thorny cargo]

Do u have a domain ? Why dont u make the user download it via a url ? Push the video into a temp folder, tell the user to download it within 5 minutes . So you wont have discord attachment size limit

[summer dust]

yes i have

[summer dust]

thanks i'll try it

[pale vessel]

if it's via url wait until they find out about https://cobalt.tools xD

the command is kind of pointless

[deft wolf]

In fact, there are plenty of YouTube downloaders on the Internet

More than enough

[pale vessel]

yeah. i use that one since it supports most social medias

[deft wolf]

What comes to my mind that would be useful in this style is some kind of API for e.g. Discord bots

[eternal osprey]

hey does anyone know condition coverage criteria regarding structural testing?

why have they written a test case for the last if such that it evaluates to false and the last return statement is executed

is true seen as a condition as well?

[lyric mountain]

no, true is a value on itself

they prolly did that because return (m == 4 || m == 6 || m == 9 || m == 11) && d <= 30 would be fairly unreadable

[eternal osprey]

(31/ <= 30, 12, 1800 <= y <= 9999): e.g, (29, 12, 2023)

nope they did it explicitly to execute return true as well.

I asked around and apparently they do see it as a condition, everything that is or evalautes as a boolean. Just in such trivial cases no further tests are possible.

[lyric mountain]

that's odd, because return true is by no means a condition

it's a result, just like doing return 1

I mean, you could argue it's an unary operation

[eternal osprey]

they that's exactly what they said

it was unary something

it's vague but i ma just do what i've been told lmao

[lyric mountain]

true (unary | has one value)
1 == 1 (binary | has two values)
true ? 1 : 2 (ternary | has three values)

basically

[eternal osprey]

I see

Indeed exactly

Thank you for clarifying that!!

[real rose]

ternary operator, my lover

[lyric mountain]

aaaaaa brain is smoking, stupid ricochet calculation

let's say I have a projectile moving at an angle X towards a target, given perfect reflection, how do I calculate the projectile angle after ricocheting on the target?

[wheat mesa]

It’s the same angle

Are we talking a flat horizontal/vertical surface like a wall?

[lyric mountain]

I'll try drawing

[wheat mesa]

Or are you talking an angled surface

[lyric mountain]

projectile is moving at an angle X (global space)

I'm trying to find Y

I have a function to find out angle between A and B, if required

[real rose]

going by that image "perfect reflection" looks like 90*

which would make y = 180 - 90 - x

but if its not precisely 90

wouldnt y = x ?

id agree with waffle

[lyric mountain]

like, X being the ball's angle

if Y = X then it'd pierce the cube

since no change in trajectory would be made

[real rose]

oh so youre like

protractor

[lyric mountain]

and it's not always 90º, it might come from arbitrary angles

here's some animated context

[green kestrel]

isn't it the inverse normal?

[lyric mountain]

note the first impact (I'm bad at aiming rotating things)

[lyric mountain]

no idea, I'm lost at what to use here

if you pay attention to the projectile trajectories, it ricochets at really wrong angles

[wheat mesa]

The angle is the same, the horizontal vector is just negated

[green kestrel]

that animation is majorly lagging my phone

[lyric mountain]

what if it ricochets from below?

[wheat mesa]

Then the vertical vector is negated

Usually movement is determined by vectors and not angle + magnitude

Though you can use both

[green kestrel]

for realism wouldn't it depends on the velocity

[lyric mountain]

thing is, how do I manage to cover both horizontal and vertical cases in a single formula?

[green kestrel]

matrix maths

[real rose]

yeah

[wheat mesa]

nope

Velocity would only matter if that surface you’re colliding with can move

At that point you’d be dealing with elastic/inelastic collisions

[green kestrel]

there's a matrix op you can do on a vector that will translate it like this but I don't remember it, it's been a long time since I did maths like this myself I just use an engine

[lyric mountain]

for the walls I simply did PI - ang/2 * PI - ang since I always know when it hits horizontally or vertically

but for the enemies, there's not much way to check this

I mean, there is, by calculating the point of impact

[green kestrel]

simplest approach is what waffle said but the minute you add moving bodies, 3d space or anything complex...

[lyric mountain]

oh total realism doesn't matter much, consider only the angle part

[green kestrel]

things like pong just invert the X and Y Velocity

so if your X,Y Velocity is -1,-1, after collision it's 1,1

[lyric mountain]

guess I'll have to calculate which side of the rect the projectile hits then

[green kestrel]

or if it was -1,1 it would be 1,-1

you don't even need to do that

if you're just inverting velocities

[lyric mountain]

if I invert both it'll go back the way it came in

[green kestrel]

I assume your velocity is a 2D vector?

hmm true

[lyric mountain]

well...not exactly

[green kestrel]

I saw the image and I thought inverse normal, like light bouncing from an object in a ray trace

[lyric mountain]

the projectile displacement is calculated from its current angle * velocity

lemme get the formula I used

protected void move() {
  float[] vector = Utils.angToVec(getAngle());
  getCoordinates().translate(vector[0] * speed, vector[1] * speed);
}

[green kestrel]

there's an easy way to find out if you're in front of, parallel to or behind a plane

I can't remember the name of it

you'd use that to determine if how the vector intersects

then you invert it using the normal

which you get from the same function

[wheat mesa]

Ideally you really want to avoid using an angle directly for movement

[green kestrel]

ah yes: dot product

[lyric mountain]

everything is pre-calculated

meaning I'll lose the flexibility of calculating sin/cos at realtime, but doesn't matter much for this game in specific

[green kestrel]

you can use dot product to determine where you are in relation to what you hit I think

it makes a change to be discussing game dev here lol

[lyric mountain]

I really need to study math more lul

[frank saffron]

Your field values are empty.

[eternal osprey]

you can use a matrix to keep track of line x, and basically write an arbitrary line y in any direction, given x and the object, with an arbitrary length (but atleast longer than line x is). You then easily calculate the projection matrix of y given x, lets call it y'. There's a specific formula for that. This projection matrix y' will be the exact line that would occur if x would shadow over to y.

[quartz kindle]

your code is made for discord.js v13

you installed discord.js v14

https://discordjs.guide/additional-info/changes-in-v14.html

[past field]

I think that happened when I did this

[quartz kindle]

if discord.js was not installed before, then npm install discord.js installs the latest version automatically, which is v14

[past field]

ohhhhh

so I should uninstall it and reinstall discord.js v13?

[quartz kindle]

either that or update your code for v14

you can install v13 like this npm install discord.js@13

[past field]

I'm very new to this so I'm not sure how to do that

[quartz kindle]

^ this guide explains all the major changes

[past field]

is it necessary to uninstall v14 first?

[quartz kindle]

for example

[past field]

ok i will readthrough it

[quartz kindle]

not necessary, the new install will replace the previous

[past field]

ok i re-installed v13

but it's still saying that there's a problem with the package.json

String does not match the pattern of "^(?:(?:@(?:[a-z0-9-*~][a-z0-9-*._~]*)?/[a-z0-9-._~])|[a-z0-9-~])[a-z0-9-._~]*$". [Ln 2, Col 13]

[quartz kindle]

ignore that

whats important is what happens when you run the bot

[past field]

ok, let me run it

[quartz kindle]

its complaining that according to the NPM standards, the package name should be lowercase characters

but its just a warning, not an actual error

[past field]

that’s so random lol

[quartz kindle]

it will go away if you change the name to "name": "build-a-bot"

[past field]

ok gotcha

its not wanting to start

i did node . like normal and it's just sitting there

oh nvm its on now

just took way longer than normal

[past field]

thank you so much!

[quartz kindle]

👍

[frosty gale]

those pesky cold starts

[lyric mountain]

@wheat mesa @green kestrel managed to get it working, used a cheap solution of checking which of the collision box' lines intersect with the projectile

since the box will always be an axis-aligned square

also reworked my screen-switching system to be stack-based because it was giving me a headache, and implemented a character selection screen

eventually I'll attempt implementing multiplayer, just need to figure out how

besides that, only thing that remains is the audio system that I managed to break in earlier updates

[wheat mesa]

looks really good actually

[green kestrel]

yeah

looks fun

add explosions next and slight screen shake

will give the shots some 'weight'

and increase the speed of the whole game 50%

including movement of player ship

[quartz kindle]

i think the game speed is fine

i would decrease the movement speed of the balls flying around, and make the player ship's speed upgradable via buffs

of course you can have a "hard" mode that increases game speed by 50%

for touhou enjoyers xd

[eternal osprey]

i can send you an example of how to compute the projection matrix of a moving object onto another matrix/vector.

you use java right?

[lyric mountain]

yes but my head is smoking right now

[lyric mountain]

it is

the spawn rate of enemies that drop upgrades is too low atm

they appear in yellow, you can see one at the end of the gif

I also need to find a better algorithm for spawning enemies

I use a point-buy system, but need to make some kind of director for choosing the appropriate enemies

I ALSO need a bigger variety of them lul, atm there are only 3 enemies + 1 boss

[eternal osprey]

understandable. I will write you a little snippet with explanation for each step.

might help you out

how are you currently representing your objects/directions? Using vectors i assume?

[lyric mountain]

Depends

Projectiles have their movement vectors calculated from the angle applied on the forward speed

The other entities are simple x/y movement

The repo is public btw, if you want to see it

https://github.com/ygimenez/GameTest

Name change is still todo

[lyric mountain]

Regarding this, don't worry, my sines and cosines are pre-calculated

[wheat mesa]

I still think that you should be using vectors instead of angles

Like you can have an angle but it would be significantly easier to use both

[lyric mountain]

Calculating the projectile path would be considerably harder without angles

[wheat mesa]

You can keep both

[lyric mountain]

I kinda do use vectors tbh, like

[wheat mesa]

Angle can be used for updating the position but for collision resolution it’s much easier to use vectors

[lyric mountain]

A projectile moving at 45° would have [0.5, 0.5] movement multiplier

I just apply the projectile speed over that

[lyric mountain]

Angle is only for movement

And hitbox

[wheat mesa]

oof angled hitboxes are rough

[lyric mountain]

Kinda, but java helps a lot at that

I'm already working with affinetransforms, so I just check if both shapes intersect

proj.getCollision().intersects(ent.getCollision()) basically

Ofc I won't be able to use my ricochet logic on that, but angled hitboxes only really matter for ultra long projectiles, like a laser

Now that I think about it, perhaps the formula gpt gave me earlier was probably right, I found that most of my issues were that the projectile was colliding twice, so changed direction twice

It was atan(-sin(ang) / cos(ang)) or smth

[dusky idol]

Can someone please explain what bot sharding is and how it helps? I've no idea whatsoever so start from basic

[sharp geyser]

At a certain point the limit of servers your bot can handle will impact your performance and even the ability to be invited to servers. Because of this discord has implemented a system called sharding which essentially splits your bot into multiple "instances" as one would say. This allows your bot to handle more servers and not spam the api and gateway. The way sharding works is when you make a connection to the gateway you send a shard id and the number of shards your bot spawns. This creates multiple gateway connections and splits the guilds amongst those shards. To handle what guilds you need some libraries give you helper methods to broadcast to all shards to find the guild you need or if you know the id you can fetch it.

With discord.js they make sharding stupid simple but there is also libraries that add more features

[dusky idol]

Sounds pretty complex to implement. Regarding the js part, I sadly work with py so I'll have to do some research soon

Also is it just in-code stuff? Will I have to make some hosting-side changes to assure that the bot works perfectly in all guilds

[sharp geyser]

No changes really need to be made hosting wise just make sure you have enough juice to support such a large guild size

It’s also not hard to implement at all

Especially with the progress of libs

What python lib do you use? Discord.py?

[dusky idol]

Ah so basically I'll have to have a stronger hosting to assure the performance

[dusky idol]

disnake.py

[sharp geyser]

Well it’s not a necessity but with more guilds the more resources it’s going to use as it’s doing a lot more in response

[dusky idol]

Right now it's in 440 guilds so I believe I'm good for a while. I got told that I'll have to get over sharding once it crosses 1000

[dusky idol]

That's fair enough, considering the amount of commands it receives per hour I can tell that there's gonna be performance issues with time

Eitherway thanks for assisting, I'll probably revisit this channel when I actually have to implement it

[sharp geyser]

https://docs.disnake.dev/en/stable/migrating.html#sharding

[dusky idol]

I'll go over that now

[sharp geyser]

Yea once you hit 1k or more it’s a good idea to start sharding it will split the guilds evenly amongst shards

[dusky idol]

Also another doubt, all of these shards are hosted by one same provider right? Or will I have to get 2 seperate hosting plans to host both shards? Does that sound silly

[sharp geyser]

Nope it’s all hosted on the same instance

[dusky idol]

Alright, so are there any changes for the users of the bot? Or they won't find any difference

[sharp geyser]

Splitting the workload amongst multiple providers is not really useful unless you’re really doing something wrong or your bot is so big it needs that much resources

[sharp geyser]

No changes for users at all

It’s all a you thing as the developer

[dusky idol]

Ah awesome I'm less worried then

[dusky idol]

Got it

Also is there any issue if I just shard the bot right now?

[sharp geyser]

No but it’s unnecessary

You’d be causing yourself more of a headache

[dusky idol]

Got it

[quartz kindle]

its a good idea to start looking into it, at 1.5k its recommended, at 2.5k its required

[sharp geyser]

yea

[dusky idol]

Makes sense, so it's only guild based or does user count of guilds has something to do with it

[sharp geyser]

Guilds get allocated to shards typically at 1k per shard

[quartz kindle]

only guild based

[sharp geyser]

So 1.5k guilds with 2 shards is 1 shard having 1k the rest will go to the other shard

[dusky idol]

ah right

[quartz kindle]

not exactly

[sharp geyser]

oh?

[quartz kindle]

they will each have ~750

[sharp geyser]

[dusky idol]

so for example if a bot has 5 shards, won't it be slower than a bot which is in less guilds and no shard at all

[sharp geyser]

I thought they made it spread out for 1k per shard

[quartz kindle]

shard allocation follows a specific rule based on the guild id

[dusky idol]

i mean overall the performance is gonna get effected as its in more guilds

Also some commands of the bot processess all guilds it's in. For example
for i in bot.guilds: if ctx.author in guild.members: do this do that

[quartz kindle]

pretty much yes, but 5 shards with 1k each will be better performance than 1 shard with 5k guilds, since it would overload the process

[dusky idol]

would that be a really big issue once the bot is in many servers

[dusky idol]

I see

[quartz kindle]

those commands will need to be rewritten to account for shards

each shard will run on its own process, so your code only sees the current shard

[dusky idol]

so ill somehow have to add all shards into the commands is what youre telling me

[quartz kindle]

for example, right now your bot runs in 1 process, so everything is inside the same program instance

[sharp geyser]

you can broadcast to all shards tho if need be

[dusky idol]

when a user runs a command in a specific server, won't the bot just see which server he ran it in and use the shard for that server automatically?

[quartz kindle]

when you have 2 shards, your bot will run in two processes, like if you made python bot1.py and python bot2.py

where each bot handles half the guilds

[dusky idol]

oh

[quartz kindle]

but thats done internally by the library

[dusky idol]

i see

[quartz kindle]

and the library provides communication between processes

usually

so if your command needs to access data from other shards, like all guilds in the entire bot, your code will need to send a message to the other process to request that number

and wait for the message to return with the result

thats called broadcasting

[sharp geyser]

ahem

[dusky idol]

ah this makes it clear

[quartz kindle]

you will need to check if your library has that

[sharp geyser]

Most libraries give you methods to do this

so you dont need to do it yourself

[dusky idol]

i see guess ill need to read/ask at the library's support server

Also for a bigger project, like a bot in countless servers, what resources are a must have hosting wise? Will more Ram or vCpus help?

[quartz kindle]

this is the sharding formula:
shard_id = (guild_id >> 22) % num_shards

[sharp geyser]

is that shifting the id 22 bits?

[quartz kindle]

for a python library, you can think about on average 200-400mb ram per shard, or per 1000 guilds

[dusky idol]

is that an operator

[quartz kindle]

ideally you should have 1cpu per shard, but usually thats not needed, a single cpu can usually handle more than one shard easily

[sharp geyser]

bro im so tired I frogor what >> does outside of c++

😭

[quartz kindle]

yes

[sharp geyser]

what does that even do

an id is a stringified bigint

[dusky idol]

The current hosting plan I'm using is this one https://prnt.sc/SerSCfzLbhJH

[sharp geyser]

at least in js

since js can't handle big numbers

[dusky idol]

I believe it's good enough for a good while?

[quartz kindle]

that should be good enough for 50k-100k

[sharp geyser]

8gb of ram is fine

[dusky idol]

thanks a lot

[sharp geyser]

Unless you use djs /s

[dusky idol]

hm

[sharp geyser]

500mb of ram used just on launch 💀

I wish this was a joke but djs uses a lot of ram

[dusky idol]

lmao that sounds funny

[quartz kindle]

yes, you need to convert it to bigint to do that in js

this is what a snowflake is made of

[dusky idol]

the bot still uses a lot of ram tho i believe and it connects to the database everytime someone runs a command

[quartz kindle]

shifting to the right by 22 bits basically cuts off the instance and sequence parts

and leaves only the timestamp

[dusky idol]

the network usuage for the bot is usually really high

[sharp geyser]

so its a 64 bit int

[quartz kindle]

yes

[sharp geyser]

well 63 by that math, but yknow

probably has some overhead

[quartz kindle]

yeah, to account for future timestamps

41 bit timestamp is good until 2039

then you need 42 bits

[sharp geyser]

gotcha

so it shifts is 22 bits and then does a modulo of the number of shards

[quartz kindle]

yes

[sharp geyser]

now correct me if im wrong, but what the fuck does shifting it 22 bits even do

[quartz kindle]

so depending on the guild's creation date, it will be moduloed into a specific shard

[sharp geyser]

957347862314905610 like take this snowflake for example what does shifting it 22 bits do

[dusky idol]

wait do you code bots in c++

[quartz kindle]

extracts the timestamp from the id

[sharp geyser]

🤔

[quartz kindle]

^

[sharp geyser]

see I know how to count in binary but idk how to use >> and such

[quartz kindle]

957347862314905610 >> 22 = 228249517039

228249517039 = timestamp for the creation of the id

aka the date when the id was created

[sharp geyser]

where does the 22 come from tho

[quartz kindle]

^ lol

https://en.wikipedia.org/wiki/Snowflake_ID

[sharp geyser]

but unless I am wrong, 22 bits is more than the timestamp no?

im also tired so I am definitely wrong

[sharp geyser]

dear god no

[quartz kindle]

moving 22 bits to the right, cuts those bits off from the righ to the left

leaving only the bits on the left

[sharp geyser]

right right

[quartz kindle]

so its removing the sequence and instance parts of the snowflake

[sharp geyser]

binary is right to left

[quartz kindle]

and extracting the timestamp

[sharp geyser]

not left to right

[quartz kindle]

ye

[sharp geyser]

so it would start where that first instance is, and end at the last part of the timestamp

[quartz kindle]

i use js lol

not discord.js tho

[sharp geyser]

its exclusive not inclusive right?

[sharp geyser]

ignroe my shitty writing

doing this with a mouse

[quartz kindle]

yes

it removes 22 bits from right to left

[dusky idol]

What database do you guys stick to

[sharp geyser]

but it doesn't include the last part of the instance

[deft wolf]

Sounds like my bot

[sharp geyser]

so its exclusive in its operation right?

[quartz kindle]

its inclusive from right to left

[sharp geyser]

inclusive?

🤔

[quartz kindle]

i mean when counting lol

[sharp geyser]

ah I meant when performaning the shift

[quartz kindle]

but yes it excludes X number of digits

[sharp geyser]

it doesn't include that last I

[quartz kindle]

from right to left

[deft wolf]

Mongo db

[sharp geyser]

it just starts there

[sharp geyser]

postgres

keep in mind the db you use matters depending on how much you want to spend

[quartz kindle]

sqlite

[sharp geyser]

sqlite has its limitations and works based off the disk

postgres is in the cloud but it scales differently

mongodb is a shitty db imo, cause scaling it is so damn annoying

[dusky idol]

I see, I've the code written for mongodb

[quartz kindle]

sqlite is more than good enough for 100k+ guilds

[dusky idol]

hm

[sharp geyser]

just don't expect to store any data thats json or arrays

unless you stringify it

[quartz kindle]

ye you need to model your data into table-based scheme

[dusky idol]

I'm usually just storing object types on the database

[sharp geyser]

unless sqlite has advanced since 2019

[quartz kindle]

same with postgres tbh

[sharp geyser]

postgres allows arrays

but I hardly ever use em

[quartz kindle]

although postgres supports json and arrays, its not recommended

[sharp geyser]

I model my data around tables and relations

[quartz kindle]

ye

[sharp geyser]

cause that is what sql is about

[quartz kindle]

exactly

[sharp geyser]

sql is meant to be relational

and to model your data exactly what its meant to be

[quartz kindle]

plus, disable all the safety options in sqlite and you get a fast af db

:^)

[sharp geyser]

a mistake I made in my early days was storing data that was meant to be attached to a table with multiple values was to use an array

and push to it

💀

[sharp geyser]

only you would be someone that'd do that

[quartz kindle]

yup

[dusky idol]

The free plan?

[quartz kindle]

i do backups so i dont mind losing data

[sharp geyser]

dont do what tim just said

[quartz kindle]

there is no plans

[dusky idol]

oh

[quartz kindle]

sqlite is free

[dusky idol]

I never worked much with anything except mongo sadly

[quartz kindle]

you run it inside your host

[sharp geyser]

the only thing sqlite costs you is your sanity and disk space

[quartz kindle]

lmao

[dusky idol]

ah i see

[quartz kindle]

sqlite is good af

[sharp geyser]

its good for prototyping

[quartz kindle]

i get 0.1ms latency on reads and writes

[sharp geyser]

but I will 100% use a cloud db for anything that matters

imagine storing your data in an sqlite file and running windows 98

:D

[quartz kindle]

lmao

sqlite technically supports more than 1tb of data

but my sqlite file is like 20mb rn

[sharp geyser]

it should theoretically support as much as your disk no?

or does it just shit itself at a certain point

[quartz kindle]

there are some limitations like everything

[sharp geyser]

fair

stupid db /s

uses the disk but not even fully

smh

should write sqlite in rust ;)

[quartz kindle]

uh...

[sharp geyser]

its likely the numbers

[dusky idol]

How many users/guilds is the bot in

[quartz kindle]

~10k

[dusky idol]

ah thats awesome

[sharp geyser]

still waiting on that astronomy api

the only bot I will ever make

is an astronomy bot using tims api

:D

[dusky idol]

my mongodb is at 4mbs something and it's in 500 guilds

[deft wolf]

Automod moment

[sharp geyser]

my db is at 400gb but thats because I am too lazy to delete test data /s

[quartz kindle]

working on it :^)

[sharp geyser]

my g

its been since 2019

😭

[quartz kindle]

ye

lmao

but this time im actually working on it

[sharp geyser]

lmao

[quartz kindle]

because i have a paying client waiting

[sharp geyser]

you said that every single year

[quartz kindle]

lmao

i g2g work

[sharp geyser]

how much they paying

👀

[quartz kindle]

25 bucks per month

lol

[sharp geyser]

dayum

easy money

I will pay 40$ a month if you actually complete it /s

[dusky idol]

The conclusion I came up with after working on a few projects is that card collection bots never go off trend

[sharp geyser]

nope but there are so many of them its useless

[dusky idol]

Yeh it's just the lack of creativity in them

I'm working at a bot following the similar theme, just taking it a step further so it's doing quite well

[sharp geyser]

It used to be fun making bots, until you realize no one fucking cares about the art and just copies everyone

[dusky idol]

yes it's sad, so many bots have the same repetitive concepts

[deft wolf]

Because many people think that creating a bot will bring them a lot of money. Everyone wants a piece of this cake for themselves

[dusky idol]

Making/owning a discord bot has to be the least rewarding task to take on honestly

Not including the bots you make for others at commissions

Obv there are exceptions but in 9/10 cases it has to be a lot of work for a very small amount of income. Considering how hard it is to advertise a bot with all the competition

[deft wolf]

This is true, and often those bots that are really worth attention quickly turn out to be completely unprofitable and people abandon them

[sharp geyser]

making a discord bot to earn money is the stupidest idea ever

most of the time unless you are very luck you are breaking even

or making a very little profit margin

[lyric mountain]

for bots you'd essentially want a connection pooler

[dusky idol]

For me that's just language of gods

[lyric mountain]

pymongo, for example if you use it, it has a connection pool

basically it keeps N connections open and simply reuse them when needed

[quartz kindle]

if you're using an external database, you need to keep the connection always on

opening and closing it every time it very wasteful

but thats likely not whats using most of the ram

most of the ram usage in discord bots comes from the library caching all the discord data, like users, members, channels, guilds, messages, etc

[dusky idol]

ah got it. thanks both of you

i gotta see where I can open the pool from

[lyric mountain]

a tip if you want to reduce ram usage, is to disable presences and message content if you dont use them

or disable anything you dont use tbh

[quartz kindle]

if you have the presences intent enabled, thats gonna hog your network like crazy

presences literally account for like 90% of a bot's network traffic if they are enabled

also, if your library is not already using compression, turning it on will also save a LOT of network traffic

[neon leaf]

Is there a more efficient json parse / stringify than the default in nodejs? Like something that you give the data schema beforehand and it can optimize it's code to stringify that schema

[quartz kindle]

yes

if you have the schema, there is a json library with schemas

https://www.npmjs.com/package/fast-json-stringify

[neon leaf]

What's it called

O

Thanks

[quartz kindle]

alternatively, if you want to go even faster and smaller, you can move away from json

for example messagepack or protobuf

both are binary formats that are faster and more efficient than json, but they are not human readable

protobuf uses schema, messagepack doesnt

[neon leaf]

Well the issue is that my API is sending quite big jsons

Around 400kb

And they sometimes take very long

Sometimes 200ms

Sometimes 3sec

[quartz kindle]

you can give one of those fast json libs a try

alternatively there is also something you can do to speed it up by quite a alot

take all the parts of your data that are fixed/predictable and create a json string with string interpolation

and only use JSON.stringify for things you have no control over or that are too dynamic

[dusky idol]

I've them disabled thankfully

[quartz kindle]

very small sample size but it demonstrates the performance difference between JSON.stringify and raw string interpolation

not sure how this difference scales tho

also check if your api has any "cacheable" parts and pre-compile json strings for those parts

[neon leaf]

Yeah I think I'm gonna cache full json string

The api doesn't update often

So it's probably fine

[quartz kindle]

cool

[neon leaf]

The funny thing is

Someone managed to take down the entire server

By spamming those 400kb requests

Lol

[quartz kindle]

Lol

[sage bobcat]

One message removed from a suspended account.

[surreal sage]

YES PERFORMANCE API INSTEAD OF DATE

[lyric mountain]

btw, wouldn't jit simply ditch the interpolated string as a no-op, thus giving a much smaller result?

stringify cant be ignored since it's a function, but the string is immutable

[quartz kindle]

if it were ditched it wouldnt take 60+ms

[quartz kindle]

lmao

[lyric mountain]

now I'm worried it wasn't ditched

why didn't js ignore that no-op loop?

[eternal osprey]

i see will have a look and based on that send you a message on what you can do to project the angle.

[quartz kindle]

i dont know the internals too well, but i believe object access is difficult to predict

i guess it doesnt realise its a no-op until after it accesses the object

property access might invoke getters and such that still need to run even tho its a no-op

[coral phoenix]

what's the best way to deal with a lot of options in a command?
in discord.js

it feels weird just having a lot of getString and const

[sharp geyser]

not much you can do

[coral phoenix]

I'll just do it like this never mind

[sharp geyser]

Are you going to be using these multiple times

like what is the use case here because you are doing this inside a switch/case

[coral phoenix]

it's an odata filter and my idea is to modify it based on the user request

and looking through the minecraft marketplace database

[sharp geyser]

🤔

yes but like, you are doing this inside a switch case

so this leads me to believe you are going to be using these options multiple times

so this is not the best way to handle this if thats the case

[coral phoenix]

oh I a lot of sub commands the match and case is just for the search command

[sharp geyser]

Okay, ig do what you want

[sharp geyser]

I just am not certain this is the best way to handle this, assuming any other case statements also rely on the options

[coral phoenix]

I don't think I'm following
I have the switch statement for each command and sub command
they are all in their own scopes and get broken after it ends

is there a better way?

[sharp geyser]

woah woah woah

now I think you are doing something seriously unecessary, unless I am not following

May I see the rest of the code? if its not too much to ask

[sharp geyser]

oh god

[coral phoenix]

old code I'm going through it and optimising it but yeah

[sharp geyser]

That's a nightmare

[coral phoenix]

tell me a better way to do this

[sharp geyser]

Realistically you should not be handling the code like this, at least with commands.

Now i'd recommend making some sort of cmd handler that can handle sub commands.

Using a switch/case statement like this is by far the worst option

[coral phoenix]

but why are they bad?

aren't they faster than having if statements for command handling?

[sharp geyser]

because its messy, and even if they are "faster" it isn't always the best thing to use. Just like with if statements, switch/case also has its uses and stuff it is not meant for.

Also faster != better code

[coral phoenix]

ehh

[sharp geyser]

I recommend making a command handler, either a class based one or a function based one.

you will have an easier time managing everything rather than in a nested switch/case

though if you refuse to make any changes, then at least make functions to group your command code together and call them in the case bodies

[coral phoenix]

I just want to finish this bot as fast as possible I'll worry about making it readable after it's done
I've been working on it for the past 3 months

[sharp geyser]

suit yourself

Im just telling you that its a bad idea to do it the way you are doing

but its ultimately up to you

mind you thats what you asked of me so

[coral phoenix]

I appreciate the feedback

what I do normally is first get the code/command working and then refactor it to make it readable

at least that way suits my style

[sharp geyser]

its not even about readablity tbh

while switch/case statements are relatively faster at lookup than if statements it isn't meant to be a fix all solution

sometimes switch/case just doesn't make sense to use

and tbh, in this case neither would if statements

[coral phoenix]

well ok

[sharp geyser]

the way i'd personally do it is

1. Make a commands folder
2. Make a command class that handles loading any files that has a class that extends it in a specified folder (e.g command folder)
3. Load it then call the run method (or whatever you decide to call it) and pass in the appropriate params to it e.g for interaction commands pass in the interaction.
4. Write some commands

with this you can extend this to allow command level permission checks like some frameworks do (namely sapphirejs)

[coral phoenix]

yeah I'm already working on that
one of the issues I have is that I have 3 global databases that most commands rely on
I want to try exporting them and pass them to the other files but always was too lazy

[sharp geyser]

you use 3 different databases?

ones that you own and control?

[coral phoenix]

yeah

[sharp geyser]

🤔

why?

that seems like a hassle

[coral phoenix]

one for liked accounts to the bot and language control
one for stats and logs control
and one for extra items like linked channels, creators database, bot bans etc

they are firestore databases

trying to optimise them to reduce the amount of reading and writing to the databases

[sharp geyser]

but the point of databases is to handle the read and write

you are just adding more overhead by using multiple

[coral phoenix]

firebase has a limited amount of them to do in a day unless I need to pay

[sharp geyser]

then dont use firebase

I assume you host this bot on a vps right?

postgres is free

even mongodb is free

firebase is a terrible db imo cause it costs to use, which shouldn't be a thing

[coral phoenix]

I use firebase because I like the service and I'm already balls deep

[sharp geyser]

fair enough

[coral phoenix]

the read are writes are so much that it doesn't matter

[sharp geyser]

not only are you balls deep but so is firebase, its a terrible service for what it offers

[coral phoenix]

20k writes, 20k deletes and 50k reads per day

[sharp geyser]

rookie numbers

databases can handle that and more so long as you use pooling and even without pooling it can still handle a hefty amount

[coral phoenix]

it costs very little aswell

like $0.03 something for 100k writes

well 0.03 for reads and 0.1 for writes

[sharp geyser]

yknow how much that is if you do 100k writes a day

[coral phoenix]

Ik I don't even need it lol but I find the service great

I'm having a partnership with some companies soon and it's doing it's job flawlessly

[sharp geyser]

neat

well good luck

I still think tim is right and discord channels are the best db @quartz kindle right?

[coral phoenix]

lol

[lament rock]

Someone I know made a library for this and I hate it so much

[sharp geyser]

I think I know the lib you are talking about

[storm kernel]

Every technology that sticks around this long has a proven purpose or niche 🙂

[lyric mountain]

and cortana?

[quartz kindle]

indeed

i cant find the original repo for that old discord-fs lib

now there's a shit ton of them

[deft wolf]

What do you think about the possibility of setting a banner for bots?

[quartz kindle]

here i found it https://github.com/bobisai/discord-fs

the readme is a solid 5/7

[charred nest]

i pooling

makes life sm easier for connections

[quartz kindle]

who needs pooling when you have a memory mapped db :^)

[charred nest]

is discord giving anyone else an issue with updating their app directory info its been over a week and the only value it wont edit is the expanded desc

[quartz kindle]

i havent touched that in years

no idea how mine looks like

[charred nest]

LOL gotcha

the current for mine is so ugly/outdated and no matter what i do it wont update it. discord was like 'oh usually takes 24h' but its been a week

[quartz kindle]

weird

[charred nest]

im wondering if certain characters aren't able to be used i use ⸝⸝➜﹒to format something in it but i don't know if that would be why it just wouldn't update

[north cairn]

guys i was trying to get started to cloudfare
i installed it and did wrangler login and it opened a webpage where it asked for consent..i clicked allow and then this

[spark flint]

it creates a temporary web server on localhost for you to verify with

now you are logged in with wrangler it won't be live anymore

[north cairn]

what do i do

to fix it

[spark flint]

nothing

you have already verified

thats just to login with cloudflare, nothing else

[north cairn]

huh? so i dont need to do wrangler login??!

[spark flint]

have you already done wrangler login

and did you click login on the cloudflare website

[north cairn]

bro i have logined in another tab at cloudfare workers

idk abt wrangler

[north cairn]

i did type it in shell but when it opened webpage..that problem occurred

[ashen scroll]

hi i need some serious help like one of the serious one i am stuck in logic part idk what to do

its a logic part not code error and enything

[north cairn]

someone help with this

[solemn latch]

So youre still trying to login?

[north cairn]

i am needing to

[solemn latch]

Are you using a remote machine?

IE, you're running wrangler somewhere not on the machine you're opening the browser on.

Like a vps

[north cairn]

i am doing on replit

[solemn latch]

Wrangler is typically intended to be run locally

But: https://developers.cloudflare.com/workers/wrangler/commands/#use-wrangler-login-on-a-remote-machine

[north cairn]

so i cant do on rpelit?

replit*

[solemn latch]

Did you open the link?

[north cairn]

yea

[solemn latch]

Should explain everything you need

[north cairn]

curl <LOCALHOST_URL>
where do i do this

in another tab or another shell

[solemn latch]

I dont use replit, so I cant answer that tbh.

I've never heard of wrangler being run on replit, if someones done it before there might be a guide online specifically for that.

[thorn spruce]

Hey, so i'm using sequelize as ORM and this happened,

as you can see for unknown reason this user_id isn't converted in string and i checked my types etc and i use Snowflake from Discord.js which is basically a string and even in my sequelize configuration for this table it's

    user_id:{type: DataTypes.BIGINT({length:49}),allowNull: false,references :{model: Players,key: 'user_id'},},

but for a reason i don't know it doesn't work for this specific ID 447880780019138560

Just found that's not from sequelize, my integer code treats the id as an integer

but this one only

[green kestrel]

how many here are adding banners to their bots rn?

[deft wolf]

Not now

I only tested it on my other bot

[spark flint]

me

its funny because its already bugged

bots shouldn't have that tag

[green kestrel]

lol didn't see the nitro tag on mobile

[green kestrel]

it's technically correct; bots have all features of nitro

[rustic scarab]

Me wondering why the command is not giving out the role for the member.
Meanwhile the code:

[spark flint]

skill issue

[green kestrel]

skull tissue

[lyric mountain]

another character

still need to write the description for it

basically a very agile ship with boomerang projectiles, which can pierce and hit once every 100ms

and can blink to the last projectile fired

fps is low on gif only btw, had to limit it to 30fps

[solemn latch]

Has anyone played with this?

https://developers.cloudflare.com/workers-ai/platform/pricing/

This is really cool https://developers.cloudflare.com/workers-ai/tutorials/build-a-retrieval-augmented-generation-ai/

[spark flint]

Yess it’s great

[frank horizon]

how do you do that 🥶

ohh no way they released it officially

[radiant kraken]

it's probably intentional to drive more nitro users

[surreal sage]

dead chat

[deft wolf]

It is what it is

[pale vessel]

it's what it's

[cloud bough]

is it possible in current discord api to send components inside of an embed?

Ive been looking around and there really isnt much on the topic

Nevermind, I answered my own question. "Embed" Doesn't have any property for components 😦 sad times

[deft wolf]

You can add components under the embed

[eternal osprey]

i just discovered that cloudfare doesn't use normal hashes using a hash function for protection, but they use a random generated hash based off fucking lava lamps??

that's so sick, who the fuck came up with that idea though. Genuinely 1000iq

[spark flint]

lmfao yeah

[eternal osprey]

madd

[lament rock]

I hate you for this /s

[sharp geyser]

It’d be better if they used out of context top.gg

[lyric mountain]

Yeah they have an isolated room with many lava lamps and a camera to sample the bubbles' position

[radiant kraken]

not really the bubble's position, they take a picture of all of the lava lamps and use the resulting image bytes to seed the hash afaik

[lyric mountain]

Ah yeah

[trail crystal]

Hi

[low orbit]

What if there's an earthquake

[radiant kraken]

they'll just buy another set of lava lamps

[neon leaf]

just a few relations

[small tangle]

They even invite you to visit the room as you add even more randomness to the resulting image

[frosty gale]

im designing a chat app which uses websockets in browsers for relaying events to users of course, but I'm wondering what the best way would be to handle this, thinking big production scale

should i delve in things like compression? i heard compression for js with things like zlib sucks because of its fragmentation, now this was for node so not sure about v8 in browsers (or even spidermonkey)

but given the small nature of 99% of messages i doubt compression would provide much benefit so id rule that out

i was more interested in using BSON instead of raw JSON since that would save massively on transmitting redundant JSON things like quotes and reusing names

[eternal osprey]

i think that they got a backup...somewhere

backup lavalamps

but on the other hand, the room must be pretty secured or not? Maybe like shock absorbing concrete coatings or sum

[dusky idol]

I've never tried either Karuto or Sofi bot in my life but one of my bot users wants me to implement a feature similar to those bots. How does that work? I don't believe if discord allows me to track what account belongs to which user. Isn't this similar to IP tracking or something? https://prnt.sc/2H0wJXMY3ACn

Well to people who cant look into image I'll copy paste the text

for new players, the bot should have a verifying thing like what the karuta/sofi bot has. this will prevent people from using their alts as it wont let them verify if they already have a main, you can like add this when theres more people using the bot or something

[deft wolf]

Comparing the IP addresses of two accounts is probably the only option when it comes to Discord, despite the fact that if someone wants to, they can quickly bypass it using a free VPN

Or if, for example, someone is able to register using mobile data on their phone and on their computer

[dusky idol]

Thought so, isn't it quite risky for any user to play your bot given that it tracks down IP?

Even tho the bigger bots most likely won't leak your data or use it for suspicious activities, still overall they are tracking the ip

[deft wolf]

Yes, but the IP address is not as "sensitive information" as it may seem. An ordinary Discord user doesn't have to worry about this, it's worse if you are a "public person"

Of course, there are data and password leaks, but if they are not interesting in any way, no one will be interested in them

[dusky idol]

Got it, thanks a lot

[past field]

is it a lot for me to code in a listening event for my bot coded with discord.js with chat gpt?

I'm sure there's a node module I have to install but I just have a feeling that is a lot more complicated than a node module and listening event

[quartz kindle]

compression is good if you can maintain a shared context like discord does

as well as protobuf instead of json

protobuf + zlib is pretty much state of the art bandwidth savings, you're probably looking at 90-95% size reduction

and cpu-wise its probably gonna be faster than json

but you need a pre-defined schema to use protobuf

[wheat mesa]

I have no idea what a “listening event” is

I highly recommend against using chatgpt since the code it generates is pretty garbage

[past field]

the events that you put in index.js

[past field]

and i mean like, having the bot respond to @ as chat gpt

like if someone @‘s my bot a question, it will respond with an answer

i’m still learning discord.js and the terminology of coding so bare with me lol

[quartz kindle]

to access a service like chatgpt, that service needs to provide an API

chatgpt does provide an API, both official and unofficial apis exist

[wheat mesa]

(Also, the API is not free iirc)

[quartz kindle]

on npm you will find many packages that use these apis

so you can try one of them

[quartz kindle]

there seems to be an unofficial proxy api that is free

[wheat mesa]

Unless they’ve made it free since I last checked

Ah

[quartz kindle]

but heavily rate limited

[wheat mesa]

1 request per day ;^)

[past field]

ah ok so it’s not really worth trying to do unless i pay for an official api

[quartz kindle]

last checked almost a year ago lol

so quite likely they are dead by now

[past field]

ah ok lol i won’t even bother then 😂

[humble gyro]

its pretty affordable

for my bot i use gpt as a base for conversational feature and it costs me like 4$

[covert palm]

It's likely that such a feature will cost more than it earns, depends how you monetize it

[harsh nova]

I remember your pfp clearly from somewhere Did you used to own the hypesquad bravery server?

[covert palm]

Hey, I used to be part of the DMP and moderated in quite a lot of servers in the past, I've never owned them but probably had a moderator role in the 3 unofficial servers at some point

[harsh nova]

Yeah that's probably where I remember you from then Thanks!

[deft wolf]

Carl bot status page 🔥

[covert palm]

So glad my bot doesn't connect to the gateway. It's sometimes a challenge and not always possible depending on what you want to do, but it avoids having to deal with shards like that.

[pale vessel]

yeah, my bot does connect to the gateway, but it could still work without it

[quartz kindle]

mine also doesnt anymore

but honestly slash commends are unstable af

text message commands via gateway were much more stable

[humble gyro]

hey is there anyone here who uses the top.gg api?

[spark flint]

hi

[humble gyro]

im migrating the "v0" api

wondering if someone has a decent suite of uses to validate consistency

[spark flint]

i use reviews api, entity fetching api, search api

and probably more

[humble gyro]

uh

which api is this

those are not in the legacy api iirc

[spark flint]

theres so many different api paths i lose track

[humble gyro]

/api/*

needs bot token

e.g. to check votes

the sdks should implement the routes iirc

[spark flint]

https://top.gg/api/bots/432610292342587392
https://top.gg/api/client/entities/search?entityType=bot&platform=discord&newSortingOrder=TOP
https://top.gg/api/client/entities/264811613708746752/reviews

some of the ones i use

[humble gyro]

ah

ok

[spark flint]

requires auth for the first one

[humble gyro]

yeah the client ones are not part of the "api"

[spark flint]

incognito returns unauth

yeah

[humble gyro]

but cool

[spark flint]

i dont think https://top.gg/api/client/entities/264811613708746752/reviews should be possible tbh

just allows people to create review incentives

anyways im getting sidetracked

ok so v0 covers anything in the docs right

[surreal sage]

alr hard one

i got a file

im guessing it's sql

it's fixed width, 4096 kb

whole lot of these

Þï¾­

how can I properly decode it

[surreal sage]

basically, modify it

varbinary?

[humble gyro]

these are internal api routes

we use them to load the UI

[spark flint]

they're also passed via props im pretty sure

[humble gyro]

yeah

[humble gyro]

we cant do pagination or anything else then

[spark flint]

tbf its impossible to block that since people can just automate getting props (nextjs my beloved)

yeah

[humble gyro]

yea

its what it is

[eternal osprey]

is anyone familiar with the hoare triples and annotated programs? If so, can anyone help me to construct such an annotated program given an inference tree?

[radiant kraken]

me

[humble gyro]

do u use any of the weird obscure undocumented stuff?

[radiant kraken]

well i don't use it directly; i just maintain the Rust SDK for it

nope

[humble gyro]

ah

kk

[radiant kraken]

what about it?

[humble gyro]

im migrating the v0 api rn

trying to understand what's actually being used outside of our docs

routes will stay the same + documented flows will stay

errors are clearer now, which is nice

idk if there was a error type in the libraries

[radiant kraken]

poggies

[humble gyro]

but that's slightly different

but stuff like accessing the api with user tokens (no longer obtainable) are removed

[radiant kraken]

lesgo

[humble gyro]

just wanna keep the v0 api as little as possible

so we can move our focus towards v1

which will be actually clean

[radiant kraken]

[frosty gale]

so essentially like structs but in javascript

possible but a bit inflexible
