I'm new in web development. I wanted to create a dashboard for my bot. My bot have like 60+ shards. when user auth I want to show all mutual guilds with bot. Should I use ws to get all guilds from bot to website or should I create a api endpoint?
quartz kindle
mutual guilds is not a good idea, its very spammy, api-wise, unless you have all members cached
frosty gale
isnt it literally a case of getting all the guilds the user is in through the oauth scope and then seeing if the bot is in those guilds, whether by querying a database with said IDs or broadcasteval?
then that can be cached
real rose
yea use the oauth schope then you can check if the bot is in those servers, and if the user has admin/manage guilds
or however you wanna work that
frosty gale
for communication with my bot and dashboard i used an api setup on the bot side but you could opt in for something more complex like redis message brokers if youre fancy or websockets indeed
depends on your scale
quartz kindle
oh yeah i fogot about oauth, since you already have the user's oauth you can just add the guilds scope
sterile brook
is there smth like awaitModalCancel()? when person just closes it without submitting

For Discord? No. No events are sent if the user doesn't submit a modal

can anyone help me with puppeteer here?
client side:```js
console.log('- [client] launching browser...')
const browser = await puppeteer.launch({
headless: 'new'
})
console.log('- [client] launching browser page...')
const page = await browser.newPage()
console.log('- [client] requesting to localhost:8080...')
await page.goto('http://localhost:8080', {
waitUntil: 'domcontentloaded'
})
console.log('- [client] running tests...')
const a = await page.evaluate(async () => {
return window.a.toString()
})
index.html: ```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
</head>
<body>
<script type="module">
window.a = 69
</script>
</body>
</html>
page.evaluate doesn't work because it says that window.a is undefined, despite me using waitUntil: 'domcontentloaded'
radiant kraken
I don't think domcontentloaded pertains to script bodies do they?
nope
how do you even make puppeteer wait until all scripts are executed
sterile brook
For Discord? No. No events are sent if the user doesn't submit a modal
deum, thats sux
sharp geyser
how do you even make puppeteer wait until all scripts are executed
with hopes and prayers
hm
@radiant kraken have you tried looking into the waitForFunction?
or any of the other wait methods
something there might be able to help you
what happens if you do waitForNetworkIdle or put networkidle0 in the waitUntil
presumably that will wait until all javascript has executed at least according to stack overflow

my idiot brain took me to intergrations before trying anything else 🤣
rustic nova
Oh
deft wolf
There's another way to get the id?
You can probably fetch it in the code or read it when receiving interactions
rose warren
You can fetch it from the API. You can get the commands endpoint to dynamically fetch all command names and IDs.
That's the best way instead of hard-coding it

It’s leetcode
I could make the function even faster
By returning if the initial condition wasn’t met before the loop.
quartz kindle
is there a way to see other people's solutions and their performance results?
quartz kindle
then check if their performance results make sense, for example a solution using for loops will always be faster than a solution using array methods like .forEach or.map
because i remember one website where their results were completely non-sensical
eternal osprey
yeah I did. I was surprised i created this code and didn’t believe it so I did my research by looking at other solutions written in js. I used for loops and others usually forEach, while etc.
quartz kindle
i dont remember what was the name of the other website
but i remember they had like rankings for problems, and the top rank solution was slow af
lmao
eternal osprey
Also what i did was creating an arrow function to check whether a condition was met, others usually didn’t create a seperate function but copy pasted the checks each time
eternal osprey
but i remember they had like rankings for problems, and the top rank solution wa...
Ahahahhaha
leetcode is pretty fun and cool to learn. So far i think I know a lot about the dom and nodejs so i thought let’s do some challenge problems
quartz kindle
like, their benchmarking system was really bad and pretty much random, every time you ran the function you would get completely different results
so the guy got top rank by luck
eternal osprey
Oowhh no leetcode is pretty known for accurate results. It’s also linked to lots of companies who provide tests, reviews and challenges
quartz kindle
thats what im interested in, how accurate their results are
because js is not easy to benchmark
there is a lot of variance
eternal osprey
Lets do a quick research 🙂 I think they have a field on their website talking about the benchmarks
One sec I’ll try to find it
quartz kindle
yeah pretty much same shit
- check top ranked solutions
- copy paste them and run them
- watch the result being slower than what you initially did
- yet somehow they got top rank
eternal osprey
this was back in 2020 tho
idk over the years it got way more popular due to people talking about it etc
they might have fixed it but I’ll take the runtime with a grain of salt..
as long as my code passes the test cases I’m good ig
quartz kindle
the thing is, its almost impossible to accurately benchmark js
especially online like that
i would rather trust a loop with 1 million iterations and run my function in there
tulip ledge
Leetcode is known to be inaccurate tho
quartz kindle
because what these companies do, is they put your code in a file, and call node thatfile, and measure the time to complete that
which includes the whole nodejs spin up time, which is wildly variant
tulip ledge
Best u can do is benchmark it yourself with console.time() or create a big-O notation if your function isn’t too complicated
quartz kindle
also who knows how many machines they have to run thousands of things per day, which introduces even more variance
tulip ledge
But if you benchmark it yourself you’ll need other function to compare to, ran in the exact same environment
quartz kindle
an accurate comparison has to be always done in the same machine in the same configuration
yeah
so basically, online benchmarking competitions are a lottery, you win by luck, not by fast code
xD
quartz kindle
I see. Damn I am stupid then hahahaha
give me the top answers and your answer and i'll benchmark them for you
:^)

you can do animations with css alone
regarding buttons, you probably saw an iframe
which is a site embedded into the long description

ahhhh, the iframe. makes sense, ty
lyric mountain
worth to note, iframes cannot access the parent, so whatever scripts u got into it will only work on the site itself

so I want to delete many rows using prisma, the thing is I also need some data of the deleted rows back, not just count (the only thing included by default). how can I do that without losing performance? Im mostly deleting around 200 items, maximum 500 at a time
neon leaf
currently I have
.http('POST', '/', (http) => http
.document((docs) => docs
.description('Cancel multiple Invoices')
)
.ratelimit((limit) => limit
.hits(3)
.window(time(1).s())
.penalty(time(2).s())
)
.onRequest(async(ctr) => {
const infos = ctr.validateZod((z) => ({
items: z.number().array().max(500)
}))
if (!infos) return
const { count } = await ctr["@"].database.invoice.updateMany({
data: {
status: 'CANCELLED'
}, where: {
status: 'PENDING',
userId: ctr["@"].user.id,
id: {
in: infos.items
}
}
})
FIX SIR
return ctr.print({ success: true, count })
})
)```
so the way you proposed would be
```ts
.http('POST', '/', (http) => http
.document((docs) => docs
.description('Cancel multiple Invoices')
)
.ratelimit((limit) => limit
.hits(3)
.window(time(1).s())
.penalty(time(2).s())
)
.onRequest(async(ctr) => {
const infos = ctr.validateZod((z) => ({
items: z.number().array().max(500)
}))
if (!infos) return
const invoices = await ctr["@"].database.invoice.findMany({
where: {
status: 'PENDING',
userId: ctr["@"].user.id,
id: {
in: infos.items
}
}, select: {
id: true,
// any other data I want to process with
}
})
for (const invoice of invoices) {
// do some stuff
}
await ctr["@"].database.invoice.deleteMany({
where: {
id: {
in: invoices.map((invoice) => invoice.id)
}
}
})
return ctr.print({ success: true, count: invoices.length })
})
)```

i have a question about Angular, so basically there is a group of students who are doing an Angular course but they are having trouble with some basic JS concepts like classes, oop, inheritance, polimorphism, typescript and shit. So i was tasked with giving them a reinforcement class on those concepts, which is fine, but also they want a few examples of how they are used in an Angular context.
i've never used Angular before, so if anyone here is experienced with Angular, can you explain a little bit and provide a few examples of how Angular works and how to particularly show a bunch of people how OOP is used in Angular?
i'll be looking at some Angular docs and tutorials tomorrow, but any input, tip or example would be nice
but the basic premise is "teach students about OOP and how its used in Angular"

what is the best way to display a big size image?
I have 20 images that weight about 10mb each
I think <Image> component from nextjs can compress it right?
lament rock
Compress the images manually
Having to compress an image each time you serve it would suck up cpu power very quickly
Also serve them as webp if available
quartz kindle
doesnt the framework cache the compressed images or something?
civic scroll
i have a question about Angular, so basically there is a group of students who a...
each angular component, service, directive is a class
@Component({ /* metadata goes here /* })
export class ExampleComponent {}
so by being a class it can do one of the stuffs like
- encapsulates data and its own logic (each property in the angular component class is a state)
which is also inheritance, due to the class implementing interfaces likeOnInit - or, it can also extend other classes / components to inherit structure / logic
similar cases to polymorphism: a class that implements an interface / another abstract class
i did this but tbh the code looks ugly
in short,
any angular-extended class property is a state
all of its dependency will be updated whenever those states change
for inheritance, you can have other component classes inherit base + implementing interfaces, like OnInit, OnChange functionality of a base component class
for polymorphism, same case of overriding abstract class methods
and don't forget depency injection
export class ExampleComponent {
constructor(private / public exampleService: ExampleService)
{
// After this component is constructed, you can access the service's methods and look at its states (this component update callback via `OnChange.ngOnChange` method would also get triggered when any of its dependencies (services)' state updates)
}
}
this also applies for services and other angular classes as well
quartz kindle
i dont think i'll need to go in depth into angular and explain what is a decorator and how does it work, since they have a different teacher for that (i hope)

yeah that's a typescript feature
quartz kindle
isnt it still experimental in ts?
civic scroll
or explaining state changes
angular site has in-depth explanation of that iirc
civic scroll
isnt it still experimental in ts?
still a feature nonetheless 
quartz kindle
are angular decorators exactly the same as in ts?
can you use them in a version of ts that doesnt support decorators?
civic scroll
yes
quartz kindle
or has them disabled?
civic scroll
can you use them in a version of ts that doesnt support decorators?
they have to be enabled via a compiler flag
civic scroll
yeah
quartz kindle
so i guess i'll have to go into that subject too
i dont really like decorators as a concept, i think they are confusing and hard to understand lol
civic scroll
the flag is experimentalDecorators
civic scroll
i dont really like decorators as a concept, i think they are confusing and hard ...
you can briefly introduce it
unless you want them to also make their own decorators
which is definitely helpful
quartz kindle
nah, just so they know dafuq angular is doing when you type atComponent
from what i understood, they started an angular course, and the teacher started using components an classes and all that, and the students were like, uh... dafuq is a class?
civic scroll
i just explain that "angular would add this class to the component tree, adding necessary identifiers and some other metadata for rendering later"
civic scroll
from what i understood, they started an angular course, and the teacher started ...
oh
damn...
they will need to learn typescript and oop first before working with angular
quartz kindle
yeah thats what i was tasked with
its just that they wanted me to also give some examples of how it looks like when applied to angular
so they get more familiarized
but for the most part i will not be going into angular, just sticking with oop and ts
i wonder how much can be done in mere 3 hours (thats how long the class is gnna be)
quartz kindle
i sure hope they use vsc
civic scroll
encourage them to explore via hints
in vsc that is Ctrl + Space
quartz kindle
ye
civic scroll
you can also show additional notes / docs of a suggestion as well
civic scroll
with vsc keymap yes
quartz kindle
ah
civic scroll
not sure about others
quartz kindle
well i'll just tell them if they use a different code editor to look into how to do that there
inb4 someone uses notepad
civic scroll
yeah that works
quartz kindle
:^)
quartz kindle
code js with physical transistors
civic scroll
with crafted cpus 
quartz kindle
from sticks and stones
civic scroll
also another thing, since it's typescript
tell them to be aware of the kind of data they are working with at all times
quartz kindle
like paying attention to typings and stuff?
civic scroll
esp. one created by their code, tell them to pay attention to types, function / method signatures
yeah, and maybe also teach them how to read errors as well
civic scroll
there are 2 types: compile error and runtime error
in this case we will do type error
civic scroll
yeah type errors can be confusing
ikr
just tell em to read carefully for 2 things:
- where it is happening
- why it errored
so at least they will know what to ask for help for when they are in trouble
civic scroll
typescript also have error code associated with an error, and you can google the error code up for examples, which is neat
civic scroll
i wish 
i will go to brazil when i can
ah tim

to reduce noise
quartz kindle

civic scroll
with other part of the code (i suppose to show integrations later), just fade it to make the part you are talking about stands out more
civic scroll
but i'll need to ask first how they feel about it and what exactly they have tro...
that's a good one
so that you can see what are the main struggles and tackle one by one
quartz kindle
ye
because supposedly they already had a basic JS course
so they should already know a few things
civic scroll
at least js has top-level statements 
quartz kindle
xD
civic scroll
oh yeah
also encourage them to type the same thing in their editor
to show that it works like demonstrated
(only for simple examples)

localhost != 127.0.0.1 according to chrome/firefox
quartz kindle
lmao
eternal osprey
so i should have the app.js run on 127.0.0.1 instead
rustic nova
that wont make a different, just visit localhost:3001 within your code
aka within your fetch
eternal osprey
oowh
if i host this with ngrok or something
would i be able to set a proper domain name
for my api
rustic nova
yes, or you just use localhost to visit your site
way easier
you're currently on 127.0.0.1 and not localhost, thats why cors says no
eternal osprey
yes, or you just use localhost to visit your site
yeah but i mean once i bring the api out, it wouldn't be smart to run on localhost. Well i don't even think it would be possible without port forwarding it am i right?
rustic nova
if someone accesses your website outside of localhost then yes that wont work
eternal osprey
that wont make a different, just visit localhost:3001 within your code
i am actually doing it rn but it still throws me cors ahh issues
eternal osprey
if someone accesses your website outside of localhost then yes that wont work
i see!
rustic nova
i am actually doing it rn but it still throws me cors ahh issues
not 3001
oh where's your server
I dont understand your setup tbf
civic scroll
@eternal osprey okay so
if that is your server endpoint
you better add an OPTION handler for all the paths
rustic nova
or just go fuck all and cors allow everything during development
eternal osprey
oh where's your server
the app.listen is set to 3000
wait should i rpovide some code lmao
civic scroll
browsers often do preflight checking, which is sending an OPTION request to the endpoint beforehand to check for what is allowed to include
so in this case
you will need to add the corresponding header field on the OPTION handle
@eternal osprey
just you know, read the error carefully
eternal osprey
i have no fucking clue what preflight is
civic scroll
i have no fucking clue what preflight is
then google it?
also i just explained above
app.option('*', (_, response) => {
response.header({
// required header here
}).send()
})
something like that idk express
it's kinda funny how you don't search something up when you know it
but yeah general tip is read the error carefully
read it twice
rustic nova
make it 3
eternal osprey
just watched a tutorial about this subject
finally undestand how it works

digital swan
anyone have tips for looking for a memory leak? i tried using the chrome debugger thing but it just crashes the bot with 100% cpu usage
lyric mountain
memory leaks ain't very easy to find
some tools have a built-in profiler, which u could use to get a flame graph
ik webstorm does have it
digital swan
it takes a few days for it to become noticeable though
im rly tempted to move to digitalocean for their droplet memory graph so i can see if its caused by a certain event or something
lyric mountain
it takes a few days for it to become noticeable though
use this node --heapsnapshot-signal=SIGUSR2 index.js
when it becomes noticeable, use kill -USR2 <pid>
this will generate a heap dump in the folder you were at the moment
digital swan
would it not make a difference if im using discord hybrid sharding
lyric mountain
memory leaks dont happen like that
digital swan
its always on the clusters though
lyric mountain
is your code public?
lyric mountain
would help to see the code yeah
digital swan
lyric mountain
why are u starting intervals and jobs inside timeouts?
or actually, doing everything inside timeouts
digital swan
there was a job that relied on data that would only be available after the bot had started up so the timeout for that is to preven the job running without the data it needs
lyric mountain
u can use .then for tasks that must run after the bot is online
using timeouts wont guarantee the bot is ready at execution time, as connection time isn't constant
digital swan
it doesnt but ive never had a problem with using timeouts
lyric mountain
that's still relying on luck, but up to u
well, I'll need a heap dump to be able to find anything wrong, too many files to check
digital swan
yeah ik its a nightmare
crystal wigeon
hey can anyone help with postgres? Im using knex and currently due to high traffic on my discord bot, it suddenly disconnects Database and i get the error "connection timeout"
what can i do here, how do i debug and fix this
my pg max connections is 100
dotenv.config({ path: "../../.env" });
export default {

max: 5
},

tableName: "knex_migrations_ts",
directory: "migrations"
}
},
onUpdateTrigger: (table: string) => `
CREATE TRIGGER ${table}_updated_at
BEFORE UPDATE ON ${table}
FOR EACH ROW
EXECUTE PROCEDURE on_update_timestamp();`,
};
This my knex config
lyric mountain
you need to ping the database ever so often
crystal wigeon
maybe i need to increase the max pool?
lyric mountain
else the conn will get dropped
crystal wigeon
it is always connected to db
peoplel are active using it
it suddenly disconnects
it suddenly just throws the connection timeout error
marsh lark
I assume whichever lib (like pg) that knex uses handles the database connection
crystal wigeon
also, reduce the pool size, 100 is way too much
pool size is 5
max_connections is pg config is 100
which is normal ig?
crystal wigeon
anything in postgres log?
mmm didnt check, i think it'll log in /etc/ or something no
lyric mountain
ah yes, then ur max connections is 5 (in code)
as the pool will never go above that
crystal wigeon
yea
marsh lark
If you only have 1 shard then it definitely should be enough
lyric mountain
5 is enough, that wont be the issue

i had it here
could not receive data from client: Connection reset by peer```this is the error i got
i see in the log
hmm
lyric mountain
it's happening during some transaction, perhaps ur getting OOM
how's your ram usage?
lyric mountain
and i get the error "connection timeout"
do u have a stacktrace?
crystal wigeon
ah nop, well the stack trace is from the current commands being trying to access DB then failing
lyric mountain
but where is that error being logged?
crystal wigeon
so could be someone tried sql injection, and closed connection?
lyric mountain
like, the line where u print to the console
lyric mountain
Not what i mean
U have to be printing it somewhere
Or is it an uncaught exception?
lyric mountain
In that block, make it print the stacktrace
crystal wigeon
but its not the command that broke the connection. any new commands after the connection breaks, it sits in connection timeout until i restart the app
kk
it might be because im not wrapping the db transaction in a try catch block
hmmm but weird nothing should break there
is there a way i can reconnect if the connection drops in knex? instead of me restarting the whole app
lyric mountain
Poolers are supposed to reconnect automatically
lyric mountain
but its not the command that broke the connection. any new commands after the co...
But what command is it?
crystal wigeon
ic, https://github.com/knex/knex/issues/1833 i was reading this and it says they dont reconnect, weird
crystal wigeon
But what command is it?
ping command
lyric mountain
Hm
crystal wigeon
well i bascially make a db call to fetch some data whenever any command is called
so it fails initially without the connection
lyric mountain
What data are u fetching?
lyric mountain
How much data are we talking?
crystal wigeon
the crash happened way before
some 5 columns thats all
probably some data in where clause might've caused it
lyric mountain
U could try finding another pool manager, to see if the issue is with it

2023-08-03 14:57:01.419 UTC [2517794] postgres@izzi STATEMENT: select * from commands where alias::jsonb @> '"didn't"' and is_deleted```becuase i see this error

lyric mountain
Ur not using params?
lyric mountain
Use params in 100% of the cases
If it doesn't allow params, find another way to make it allow
crystal wigeon
`select * from ${tableName} where alias::jsonb @> '"${key}"' and is_deleted = false`
)```
This the querymm
lyric mountain
Replace raw with the proper function
Raw doesn't sanitize params
Also why is tablename variable?
quartz kindle
prepared statements dont support table name variables, so sometimes if you want to programmatically query different tables, you have to use raw
crystal wigeon
its jsut a global constant
quartz kindle
at least in sqlite
lyric mountain
its jsut a global constant
The table name?
crystal wigeon
The table name?
yeah,
lyric mountain
Hardcode it then
quartz kindle
i guess he wants it to be configurable from a json file
crystal wigeon
at least in sqlite
same in knex
yeah, im thinking thats probably why it happened
using raw
lyric mountain
Hm, then use the regular query function but append the table name with + tableName +
It won't be caught as a param, so it'll still work on regular query
quartz kindle
'"${key}"' this will never support the ' character
so you have to either remove it from all queries, or specifically find it and escape it
or use prepared statements for that part
crystal wigeon
yeah, im trying to serialize it pretty much
crystal wigeon
apparently it didnt
crystal wigeon
i just have to convert the query using knex query builder and should be fine
knex will take care of serialisation
@lyric mountain okay so i got this error this time

Hello!
frosty gale
are there any good clustering libs in js
by that i mean something which can spawn and manage clusters and distribute load amongst them evenly
not confined to the same machine either
solemn latch
Maybe I'm misunderstanding, but I dont think you would want to use JS for something like that
solemn latch
For cluster management?
kubernetes
solemn latch
For kubernetes it just starts runs containers
frosty gale
like docker containers?
what about distributing messages/tasks/commands to those instances on the api level?
google is more focused on telling you why they should sell you it on GCP rather than explaining what it can do in detail
earnest phoenix
not confined to the same machine either
I'm assuming you're talking about runtimes that can run JavaScript everywhere and not vanilla JavaScript (AKA browser JavaScript)
If so then in Node.js we provide a built-in cluster module that you can use
wheat mesa
the first damn time someone has used markdown appropriately in #development
earnest phoenix
rustic nova
Shit you're right
anyways time to ruin this moment
though I think Voltrex has used it before
haven't you?
lament rock
Task distribution is a broad term. There are many different ways to manage tasks such as round robin, random, etc.
How exactly you would determine which one is doing the least amount of work as well can be code base dependent which would require you to make your own scheduler
A chain of tasks inter-dependent on each other should also go to the same node if necessary
For example, I encode cluster IDs in button custom_ids
earnest phoenix
haven't you?
I probably have, I don't quite remember

how do i send an embed in broadcast eval?
await client.shard?.broadcastEval(async (cl) => {
const channel = await cl.channels.fetch(id);
if (!channel || channel.type !== "GUILD_TEXT") {
return;
}
const embed = createEmbed(author, client)
.setTitle(title)
.setThumbnail(//image
)
channel.send({ embed });
});```
This is my current implimentationi keep getting the error "embed" is not defined
i get a type error if i use string instead of function in broadcasteval tho https://stackoverflow.com/questions/62903204/discord-js-sharding-how-do-you-send-an-embed-message-with-broadcasteval
as seen here
marsh lark
```
await client.shard?.broadcastEval(async (cl) => {
const ...
broadcastEval only allows json serialisable objects to be passed in (apart from the client), I'd recommend serialising the embed into JSON outside of your broadcastEval and adding that json as context in the function
Also in your code you're not passing in any context at all, remember that inside the function you cannot access any local variables
crystal wigeon
gotcha, thanks lemme try this
marsh lark
So something like ```js
const json = generateEmbed(...).toJSON();
await client.shard?.broadcastEval(async (cl, { json }) => {}, { context: { json } });
yep that worked, so inside the func i can use json parse
to get back the object
marsh lark
yes
but djs already handles that for you
you dont have to pass in a string, you can pass in json as an object
so you can new EmbedBuilder().toJSON()

im not asking for code, im asking for the best approach
frosty gale

so you want to get the percentage of all the total answers for each choice?
neon leaf
yes so like "30% chose option Y"
lyric mountain
```model PollOption {
id Int @id @default(autoincrement())
pollId Int
poll...
pollanswer shouldn't have an id
Poll and User are the primary keys
it's an M-N relationship
neon leaf
pollanswer shouldn't have an id
dont I need to reference it in each option so I can know what belongs to what?
like all fields with @relation dont actually exist, they are just abstractions
lyric mountain
the middle table (PollAnswer) must have a reverence to both Poll and PollOption
as it's just making the connection between them
I sent an UML not so long ago here, lemme see if I find it
but with the FK on nutrition facts, not product
kinda messed this
basically you Poll will have and id, and so will PollOption
then PollAnswer will reference both Poll and PollOption, having 2 FKs as primary keys
lyric mountain
how would I be able to get all possible options for a poll then?
select from PollOption
frosty gale
oo btree
im surprised it doesnt use b+ trees
its better suited for database indexing
lyric mountain
I have this now
Seems good
quartz kindle
hash table best
frosty gale
hash tables are actually used in some databases still
but theyre inefficient
use too much space
and the rehashing/resizing procedure is extremely slow
frosty gale
o(1) retrieval
if you forget collisions
not sure how that factors into the performance modelling
i think its not significant enough
quartz kindle
if you forget collisions
robin hood hashing is pretty efficient at reducing collisions and also increasing load factor efficiency
with robin hood you can go up to ike 95% instead of the typial 75% load factor
frosty gale
chance is still there though
but yeah if there was no need for resizing hash maps would be op
i wonder how c++/js hash maps resize/decide when to resize+rehash
its quite a significant operation especially in large hashmaps
quartz kindle
its usually based on load factors
when it reaches a certain % of filled hashmap
i think by default its 70%
quartz kindle
90% may not be very efficient if you use linear probing
but tis fine if you use robin hood
frosty gale
actually 92% 💀
quartz kindle
xD
also, table resizing doesnt need to be sync
its can be done asynchronously and/or multithreaded
frosty gale
yeahh but adds complexity
you probably also have to make the thread wait during resizing too if it wants to set a new item
frosty gale
although for fetching i dont see a big problem considering you can keep the old container active while you copy/rehash everything
but then when do you decide when to no longer allow writes
because it might conflict with the rehash/resize
quartz kindle
like you said, you keep two containers
you create a new one with new size, and you can immediately start reading/writing to it
and you asynchronously fill it up from the old one
reads might need to check both tables for a little while, so they will be o(2) instead of o(1), mostly
but writes will be done to the new one immediatelly
frosty gale
true that makes sense
frosty gale
iterate over each old key and re-add it to the new one with some set function
and then add a mutex
quartz kindle
yeah i implemented a separate mutex per table entry
frosty gale
although what if a case exists where you do so many sets so quickly that the new size of the container gets exhausted while its still copying over the old keys
wheat mesa
Multithreaded data structures will always be an interesting thing to implement
quartz kindle
although what if a case exists where you do so many sets so quickly that the new...
either create a third table, or force a synchronous wait at that point
i think what i did was forcing a wait
frosty gale
i think at some point you need to keep track of the capacity and make it wait if adding a new key would no longer make the old keys fit
yeah
it gets quite messy but if you really wanted to you could implement it
quartz kindle
it was fun working on it, using js buffers
but i shelved it because i didnt have a good serialization solution
for the actual data
also, memory fragmentation is a huge issue
if you also implement the memory alloc for the data
instead of using pointers/heap
frosty gale
serializing what?
frosty gale
honestly for a hash map i think what you could do is allocate an entire 4kb page from the operating system hence completely avoiding malloc therefore no memory fragmentation
quartz kindle
yeah the key part is fine
frosty gale
the size is reasonable regardless
quartz kindle
the problem was i wanted to also do the allocation for the values in js buffers
since js doesnt have pointers/heap
i scratched my head quite a lot regarding fragmentation
thats why i shelved the project
in the end i figured i had to implement something like what jemalloc does, arenas and buffers with diffrent sizes
too complicated

How do i update a single value in an object in an array? I'm using MongoDB, and i just can figure out how i (through code) can do so. For example, if someone buys Tesla stocks, i want it to update the quantity.
quartz kindle
How do i update a single value in an object in an array? I'm using MongoDB, and ...
find the object in the array first, and then update the value for the property of that object
for example stocks.find(value => value.code === "TSLA").quantity = 6
frosty gale
the problem was i wanted to also do the allocation for the values in js buffers
you might just be the person that most uses buffers in javascript
... for the unintended reasons
quartz kindle
lmao
recently i stopped using node buffers
and started using only uint8array
:^)
frosty gale
basically the same thing
quartz kindle
although for utf8 encoding/decoding, node buffers are still faster
frosty gale
except uint8arrays are less flexible i think
quartz kindle
and faster
frosty gale
whats the difference between uint8arrays and buffers anyways
i imagine the underlying storage is the same
quartz kindle
Buffer extends uint8array and adds things to it
frosty gale
makes sense
quartz kindle
but for some reason, some things are slower
because they are implemented in the nodejs cpp side
quartz kindle
yes afaik
frosty gale
i think its because for ofs handle cases where the array gets mutated during interation
tribal crow

And to update it i do what?
frosty gale
for i does not
quartz kindle
if you want to make a performant thing with buffers, you need 4 things, an ArrayBuffer, a uint8array, a Buffer and a DataView
tribal crow
The update part is what confuses me
quartz kindle
And to update it i do what?
i dont use mongo so idk, but it depents on how you setup your database
if you use stull like Models and Schemas
tribal crow
yeah
quartz kindle
or if you use mongo queries directly
quartz kindle
then the Model should have a .save() method, no?
frosty gale
if you want to make a performant thing with buffers, you need 4 things, an Array...
what is an arraybuffer/dataview anyways
tribal crow
then the Model should have a .save() method, no?
yup
quartz kindle
then try that
quartz kindle
what is an arraybuffer/dataview anyways
ArrayBuffer = raw memory, like malloc
all others are views over that raw memory
tribal crow
then try that
What is there to save if i havent changed anything?
frosty gale
all others are views over that raw memory
whats the point of being able to see but not touch
quartz kindle
What is there to save if i havent changed anything?
didnt you change the value?
quartz kindle
whats the point of being able to see but not touch
you can touch
views as in, interpretations of that memory
both read and write
unit8 interprets it as bytes
Buffer also as bytes, but with additional stuff
DataView as numerical formats, ie int32, unit64, etc
frosty gale
ah okay so how to interpret the underlying bytes?
quartz kindle
ye
quartz kindle
DataView is the fastest way to read/write multi-bytes number formats, basically
including bigint
and doubles
quartz kindle
node Buffer is the fastest when reading/writing string formats, like utf8 and ascii
frosty gale
arent they stored as strings underneath or is it that npm library that does that
quartz kindle
nah, bigint is stored as a list of "words" in cpp
tribal crow
didnt you change the value?
#development message does this update the value?
quartz kindle
word is either 4 byte of 8 byte idk
quartz kindle
https://discord.com/channels/264445053596991498/272764566411149314/1137076896279...
yes, its a one-liner for finding and updating
but you can do it like this:
tribal crow
Never seen that before
quartz kindle
assuming each object in that array is a mongodb Model/Schema ```js
const TSLA = stocks.find(value => value.code === "TSLA");
TSLA.quantity = 6;
TSLA.save();
Hmmm
radiant kraken
word is either 4 byte of 8 byte idk
word is 4 bytes iirc
quartz kindle
how would bigints be written
bigint <-> buffer interop in js is limited to 64 bits, same way bitwise is limited to 32 bits. anything more than that needs multiple operations
so for example read/write bigint64 in DataView will always read/write 64 bits at a time
tribal crow
assuming each object in that array is a mongodb Model/Schema ```js
const TSLA = ...
So if i were to buy 2 shares (or whatever they're called), i could do it like this?
const Stock = stocks.find(value => value.code === "TSLA");
Stock.quantity = Stock.quantity + 2;
Stock.save();
yeah that should work, assuming the object is a valid model with a .save() method
neon leaf
Stock.quantity += 2 should work too
quartz kindle

i just dont find the purpose behind Uint16Array, Int16Array, Uint32Array, and Int32Array
when node.js is dynamically typed
quartz kindle
its for working with binary data

so im currently adding my poll endpoints to my sdk, how should I name the method used for voting and for revoking a vote (really not an important question)
I currently thought of voteForOption(optionId: number) for voting
quartz kindle
.readUint16LE(), .readUint32LE(), etc ???
sure, some formats migh require LE or BE
i think the erlang/ETF specification uses both LE and BE for example
quartz kindle
so im currently adding my poll endpoints to my sdk, how should I name the method...
if there isnt a voteForSomethingelse, just voteFor(id) should suffice
neon leaf
what about revoking a vote
frosty gale
its for working with binary data
yeah its extremely useful for working with binary data
performance is huge
quartz kindle
revokeVote
quartz kindle
performance is huge
the only problem with DataView
is that its extremely slow to instantiate
neon leaf
idk how I just came up with this horrible name
quartz kindle
its literally faster to copy a 14kb buffer than to create a new DataView

okay now the most important question in the universe, where do I put my getPolls(page?: number, search?: string) method, following options:

const api = new API(...)
api.getPolls() // option 1
api.account.getPolls() // option 2
api.poll.getPolls() // option 3
// maybe something else?
well idk what the entire structure looks like, so wherever makes more sense to you
are polls account specific? then put them in account
are there other poll related things in .poll? then put it there
neon leaf
polls are the same for every user, you can only vote if logged in
quartz kindle
if there is nothing else worth grouping it with, then put it in the root

are there other poll related things in .poll? then put it there

How is multi language usually done in bots? Are the strings moved to json files or something and then you use .replace on it?

How is multi language usually done in bots? Are the strings moved to json files ...
usually you have a file or some database which holds all the strings for other languages
and for each string you assign some kind of token like WELCOME_MESSAGE_DMS
so instead of something like message.send("welcome user!"); you would have some system which fetches the string for the desired language, something like message.send(strings["WELCOME_MESSAGE_DMS"].us);
a very rough idea amongst the millions of possible implementations
tulip ledge
yeah that's how I thought
but what if you have variables in the string that need to change?
like a username for example
do you use a token like {user} and then replace it?
frosty gale
yeah something like that, maybe a function which automatically does that and you provide an object to that function which replaces {var} with the actual values
it is messy and annoying though so many bots choose not to
tulip ledge
yeah thats why I was looking for a cleaner solution
frosty gale
would be cool if discord added automatic translations or something like that
tulip ledge
but I guess it's hard

templating system, it does replace but in a nicer fashion per se

mmmh, can you give an example? or like explain how it works?
frosty gale
actually
you could still use ${something} if you evaluated the string with eval
that would make the js engine actually compute and replace the variable with the actual variable
queen needle
but that presents security risks if it has user entered input
frosty gale
language files usually only contain strings from the developer themselves
if you want to be extra safe you could use sandbox ig
queen needle
mmmh, can you give an example? or like explain how it works?
Uhm, well it would still use {whatever} but it would have them as a duct and then when it's replacing it could use a for loop to go through and do them instead of having to replace everytime

Ever looked into i18n (internationalization) libraries?

I see that we can configure the shards. For you how many guilds max per shards would be optimal? (I have a bot that only uses command and button interactions)
deft wolf
Sharding is required at 2,5k guilds if I remember correctly
I guess 1k per shard should be good and it's default value
wicked pivot
ohh so I still have time I'm around 500
wicked pivot

Ok thank you for this information
deft wolf
You can read about it until then and think about which way you would like to go and which will suit your bot better
In discord.js, there are 3 ways to make sharding
wicked pivot
I already made the system thinking that it was around the 1k guilds that it happened and in case it happens I'm not lost
const { ShardingManager } = require('discord.js');
const manager = new ShardingManager('./index.js', { token: '...token...'});
manager.on('shardCreate', shard => console.log(`Launched shard ${shard.id}`));
manager.spawn();```
I did like thisThe above code utilizes the discord.js sharding manager to spawn the recommended amount of shards for your bot. The recommended amount should be approximately 1,000 guilds per shard
You have answer on discord.js guide
wicked pivot
So everything is good
