[obtuse gale]

are you in it? if so can you send in my dms

[drifting aspen]

you can get to the paper's via their website

[brittle leaf]

you will have to loop over the list then call Block.getType()

what are you actually trying to do?

[obtuse gale]

Stop specific blocks from exploding, i figured out a way

[rain maple]

Hi, how I can create large tablist in my plugin ?

[brittle leaf]

you loop blocklist, then if they match your requirements just remove them from said list

using list index is probs the easiest way to do so

[brittle leaf]

in what way?

[half harness]

They want to get the block material that caused the explosion
But you might be able to use block list and compare the Location with BlockExplodeEvent#getBlock

[rain maple]

I what create tablist like bungeetablistplus plugin with information on tablist

[brittle leaf]

ah, then you would send a bunch of dummy player tab list data to the client

using packets

protocollib, packetevents or good old nms can do it

you could also look at bungeetablistplus's source and find out what they do

tho id assume the exact same thing that i said

[brittle leaf]

Stop specific blocks from exploding, i figured out a way sounds more like they wanna prevent certain block types from exploding, rather then preventing the block that caused the explosion from exploding

[half harness]

They might mean like stopping beds from exploding

Idk but either way

He found a solution 🤷

Hopefully it uses blocklist()

And not some hacky method

¯_(ツ)_/¯

[rain maple]

okay, I try, thanks for help

[brittle leaf]

well beds still come under what i saidd

bed is a block type

its just a material with directional data

[half harness]

Not all beds though

Only if it was the one being exploded

I think

[brittle leaf]

thats still exactly what i said

[half harness]

Then I guess I clarified 🤷‍♂️

[brittle leaf]

from what i could tell, they wanted to prevent certain blocks from being removed in the radius of the explosion, not prevent the block that caused said explosion from being removed, which is what your message sounded like

[half harness]

He didn't really clarify which

Yes, that was what my message intended
Either way, once again, he got his solution (which he didn't post ☹️)

[brittle leaf]

fair

would be nice to have clarification if they said exploded by or was use to explode, like if they wanted to prevent certain blocks from being exploded in the explosion blast radius or wanted the block that caused the explosion to not be destroyed during said explosion, like beds in the nether or primed tnt exploding

their message was a tad vague

such fun

[half harness]

Yeah
Also I forgot that beds only explode in the nether so hopefully I didn't cause further confusion 🥲
(also minor note but primed tnt is an entity, confused me for a bit but makes sense)

[drifting aspen]

So, does TNT trigger the BlockExplodeEvent tho?

[half harness]

I don't think so
On phone so can't really check

Since it turns into a primed tnt entity

[brittle leaf]

tnt blocks are deleted and converted into a primed tnt entity, so probably not

but the primed tnt would trigger the event since its blocks being exploded event, rather then Block that caused explosion event

[obtuse gale]

I mean im trying to stop the explosion from happening, if the reason for the explosion is something specific

and i found a way by watching the interact event

[slate elk]

lmao i saw this

in showcase

very embrassing

just checking for strings

so if my resource is not leaked

but contans

cracked

LOL

it will flag

actually when i think about it t here no other way

for resources they u r not familier with their stracture

how ever

useless resource.

[pallid gale]

Not exactly useless, we use a similar thing here for Barry's automated resposnes to common issues

If barry scans a paste/error and sees something he knows, he'll respond

Similar to how that showcase works I'd imagine

[wind patio]

name your plugin CrackedEggs

[ocean quartz]

Flagged yes, as long as it's not automatic punishment that is fine
A very common false flag we get is CRACKED_STONE_BRICKS for example

[drifting aspen]

@past eagle hey, how do you manage to change the skin here? #showcase message

I thought the skin had to be signed by mojang

[solid spoke]

hey, is a support of kyori minimessage is planned?

[half harness]

I'm pretty sure the answer is no but you can ask in #general-plugins or #1007620980627230730 and specify which plugin

[solid spoke]

yeah but it cost me nothing to ask, thanks i'll post it there

[past eagle]

MineSkinAPI + SkinsRestorer, along with MojangAPI usage

[jagged frigate]

I knew it SkinRestorer

[past eagle]

For applying the skin, yes, and MineSkin to generate the actual signature and texture

The process to actually generate the manipulated image is still much more different than just applying a skin, so the system itself basically puts everything together (set-up overlays), creates the full skin png, generates signature+texture based off the manipulated skin png image and lastly applies it using SkinsRestorer to avoid having to re-log to see the skin-changes

[drifting aspen]

I was afraid you would say that

Don't you abuse the API doing this?

[past eagle]

Not by much honestly, haven't ran into an issue, although I am definitely planning to set-up soon enough a better caching system so it directly applies the same skins from the cache instead of using the api all over again to generate the skin from zero

[drifting aspen]

I think the API pool isn't really that large

So if this were to be pushed into a real plugin I think it would probably overload it

[past eagle]

There's already around 7-8 users now of this system along with other private servers using the exact same system for their skin generation, hence why I'll definitely set-up the caching to avoid future overload issues from it

Could always setup a usage limit as well so it doesn't allow usage abuse

[past eagle]

Does anyone know whether there’s a direct way to make NPCs only visible to the user that created them? Or something such sort

[pastel crow]

can anyone write me the proper code line for reducing the default armor stats ( for example: iron armor be reduced to half of its effectiveness ) PLEASE and thank you.

feel free to @ me

[distant sun]

Send the packets only to that player

[distant sun]

ItemMeta#setAttribute or something like this

[pastel crow]

sorry.... i meant like the whole .json explanation

[distant sun]

What json? Are you making a data pack?

This channel wont be very useful for data packs

[pastel crow]

i assumed i would need to make a datapack in order to drop the attributes of all armors and make that the new default for my server

[pastel crow]

also where would i be able to talk to people about this

[keen wing]

Hello how can i parse this as console PlaceholderAPI.setPlaceholders(null, "%%bungee_total%% oyuncuyu")

[remote goblet]

Bukkit.dispatchCommand(Bukkit.getConsoleSender(), PlaceholderAPI.setPlaceholders(null, "<command>"));

[half harness]

you just do null

I'm pretty sure it accepts a nullable OfflinePlayer

[keen wing]

i did (Player) null

[slate elk]

idk what the problem even to return to any player same value then

really no reason thing to do

[final scroll]

I have a custom enchantment, glow. It's sole purpose, as you can imagine, is just to make an item glow. Before the item is added, the enchantment is applied, however, after it is added the enchantment is removed. Any idea why?

player.getInventory().addItem(ITEM);
System.out.println(ITEM);

for (ItemStack i : player.getInventory().getContents())
  if (i != null)
    System.out.println(i);

[11:43:44 INFO]: ItemStack{DIAMOND_SWORD x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, enchants={glow=1}}}
[11:43:44 INFO]: ItemStack{DIAMOND_SWORD x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC}}

[fading pagoda]

how you apply it... (enchantment)

[blissful sluice]

Does anyone know the proper name for using a like queue/tracking based push system for database writes?

Like when you save a changes in-memory and bulk-writing/saving to DB on a timer etc?

[cinder flare]

Batching?

[final scroll]

Using ITEM.addEnchantment(Enchantment.GLOW, 1);

[fading pagoda]

try add unsafe

addenchantment

or hashmap adding

[final scroll]

I'll try unsafe, hold on :)

Noop, it still gets removed

[inner umbra]

Try adding it to the itemmeta

@final scroll show the whole code. There shouldn't be a reason based on that code the enchant gets removed.

[blissful sluice]

I meant more the design/ strategy thing

[cinder flare]

Yeah I mean I would call that a batching strategy

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

@blissful sluice

[blissful sluice]

Ig it's just because of the terminology/language being so different from what I'd expect it sounds off

[cinder flare]

i mean yeah idk, that's just what I'd call it in general lol, doing jobs in batches as opposed to individually

[final scroll]

This is all really, there has to be some event that's affecting it I assume? But I can't think of what that can be though.

public class TEST extends AbstractCommand {
  private static final ItemStack ITEM;

  static {
    ITEM = new ItemStack(Material.DIAMOND_SWORD);
    ITEM.addUnsafeEnchantment(Enchantment.GLOW, 1);
  }

  @Override
  public void call(CommandSender sender, String[] args, CommandSendEvent event) {
    ((Player) sender).getInventory().addItem(ITEM);
    System.out.println(ITEM);

    for (ItemStack i : ((Player) sender).getInventory().getContents())
      if (i != null)
        System.out.println(i);
  }
}

[blissful sluice]

I found the terms write-through and write-behind caching, the latter seems to match

[cinder flare]

I mean, in the specific context of databases, I think most engines now use Write-Ahead-Logs, which is like the other half of doing that lol

[inner umbra]

Hmmm. Yeah try itemmeta

[final scroll]

I also have an ItemFactory class where I do this:```java
for (Entry<Enchantment, Integer> e : enchantments.getEnchantments().entrySet())
m.addEnchant(e.getKey(), e.getValue(), true);

Same result

[inner umbra]

ItemMeta meta = ITEM.getItemMeta();

meta.addUnsafeEnchantment(<glow>);
ITEM.setItemMeta(meta);
```Or something similar.

[final scroll]

That does not exist, ItemStack#addUnsafeEnchantment calls ItemMeta#addEnchant(Enchantment, int, boolean)

[inner umbra]

Yeah not on PC so can't check the code. I wonder if the final modifier is causing an issue...

[final scroll]

I doubt it, as the enchantment is applied to the meta it should be fine. Also neither ItemStack or ItemMeta are immutable

I can try

Noop, no difference

I guess there must be a Listener causing some trouble somewhere

[inner umbra]

Yeah. I'm not seeming to be able to replicate it removing the enchant.

public class BaseCommand implements CommandExecutor {

    public static ItemStack sword = new ItemStack(Material.DIAMOND_SWORD);
    static {
        sword.addUnsafeEnchantment(Core.glow, 1);
    }
    
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("test")) {
            if (!(sender instanceof Player p))
                return true;

            p.getInventory().addItem(sword);
            return true;
        }
        return false;
    }
}

[final scroll]

I'll have to find the one Listener in my pl causing this then. I hope I'll be done before new years, wish me luck lol. Thanks for your help!

[inner umbra]

Could just disable your listeners 1 by 1 and if you only have one listener then do it by events.

[final scroll]

I could, if I knew where they all were lol. I'm too lazy to initialize them manually, so I do it via reflections when the plugin boots. So I have to find all the Listeners first lol

[inner umbra]

... hmmm well let me know if you find the issue.

[wind patio]

ctrl shift f "implements Listener"? 🥴

[potent nest]

that sounds terrible

[soft umbra]

Guys i need help So i got cutom sharpness 12 sword that i enchanted with essentials it does the same damage like sharpness 5 sword? How and why?

I have these plugins is any of them blocking the sharpness 12 or something?

oh cant upload image here

[lost river]

unsafe-enchantments in EssX config

[soft umbra]

They are enabled but still they work like normal max ones

which is weird

[brittle leaf]

post the image to imgur

also post an image of the item itself

actually, #general-plugins or #minecraft

continue there

it doesnt look like sharpness has a damage cap

[obtuse gale]

who can help me with one easy config?

[oblique heath]

don't ask to ask

just post the exact issue so others can see it and help, that way we don't have to back and forth a bunch

[final scroll]

Eclipse :p

[remote goblet]

stop using eclipse, use intellij ;3

[final scroll]

I'm way too used to Eclipse, it works well for me. The only problem is some small inconveniences every now and then :>

[remote goblet]

find god

[final scroll]

💀

I can code in it, it's fine lol :)

I can't miss what I don't know exists. I didn't know you could search like that in Intellij, so I'm not missing it heh

[inner umbra]

crtl+h on the project

[final scroll]

WHAT

omg

That's crazy ||I was crazy once||

[prisma wave]

convinced some of you are legit masochists

[distant sun]

man I have to use eclipse at work to edit some internal tool BECAUSE IT DOESN'T USE A BUILT TOOL AND THEY HAVE EXAMPLES ONLY FOR ECLIPSE and I hate every second spent in it

[half harness]

You can use intellij artifacts... If your work lets you

Actually it's prob better to just use eclipse

[distant sun]

yeah idk, the project is so weird, ive tried to import it in IJ but it didn't recognise the libraries and shit so I quit

I might try again though, using eclipse is not good for my mental health

[final scroll]

Idk why everyone hates Eclipse, it works fine imo :)

[potent nest]

it works fine until you open the code in IntelliJ and every line has a warning

[final scroll]

xd

[potent nest]

I've seen it so many times, you can tell from the code quality whenever someone was using eclipse

[jagged frigate]

What language should I learn to make plugins?

Other than Javascript

[potent nest]

if you want to write minecraft plugins, java would be the best I guess

[jagged frigate]

Only Javascript?

[final scroll]

No

Java

[jagged frigate]

How about Kotlin?

[final scroll]

Kotlin works, but most guides and forums and whatnot will be Java

[jagged frigate]

I already learned Html and css, I think I want to further my knowledge to make plugins.

[distant sun]

Facts, I hate a co-worker that refused to use IJ and the code was full of warnings, from spelling errors to unnecessary code/conditions

[potent nest]

html and css don't really help you there

[final scroll]

I'd say go Java, but if you really want kotlin works

[jagged frigate]

No, I mean I learned about website development..

[potent nest]

I'd say Kotlin is actually more difficult than Java, but easier than Scala

[jagged frigate]

I see

What the different tho?

[distant sun]

Java and JavaScript are not the same thing/similar, it is easy for a beginner to mix up the both (or for a recruiter )

[jagged frigate]

Can I use C+ or C++ to make plugins?

[distant sun]

Java or other JVM languages (idk how, I've only used Kotlin besides Java)

[jagged frigate]

I am confused, what you mean by other JVM languages

[potent nest]

In theory: yes. Is it practical: no, not at all. You'd make your life very terrible

[distant sun]

Ywell, can you explain what JVM is?

[jagged frigate]

Sorry.. I am beginner D:

[potent nest]

JVM languages are languages than can be run by the JVM, i.e., they can be compiled to Java bytecode. This includes languages like Java, Kotlin, Scala, Clojure and more

the JVM (=Java Virtual Machine) "understands" java bytecode and can execute it then

[jagged frigate]

Should I use Linux to learn Java?

[potent nest]

no, you can develop with Java on windows just fine

[prisma wave]

This but unironically

It’s kinda the equivalent of an artist using ms paint

Sure it works, but it’s limiting you and indicates you’re not super serious about the projects you make

Also this is more subjective but eclipse UI is fugly

[distant sun]

Exactly

I can barelly tell they are still updating eclipse

The flat IJ ui is not so bad I like that gradient at the top and other things

[prisma wave]

Fr, fresh out of 2004

[prisma wave]

Yeah vanilla IJ is decent, and then you add plugins and it becomes 10000x better

[distant sun]

What plugins do you use? I only got material theme and atom icons
Talking ab icons, I hate how most stuff are flat / minimalistic in comparison to the original ui, yet the buttons at the top are so fucking big (like run, build) and why is there one for plugins in the main ui??

[prisma wave]

yeah just those two really lol

[distant sun]

[potent nest]

Rainbow Brackets is nice

[prisma wave]

oh yeah that ones good too

[long dagger]

Github Copilot too

and then Minecraft Development makes developing plugins / mods far quicker

[drifting aspen]

how so?

It only creates the base project

nothing else

And it still does not support gradle kotlin DSL

[long dagger]

it has support for some Mixin stuff along with NBT data, and it can do MCP mappings

[drifting aspen]

Well yeah, that has nothing to do with plugins

[long dagger]

yeah, I meant just minecraft in general

[pastel imp]

y'all speaking about eclipse & intellij? I use netbeans at school, ngl quite like it in someways...

[wind patio]

IJ plugins I personally use:

• CodeGlance Pro
• Copilot
• Rainbow Brackets
• Statistic
• String Manipulation
• Key Promoter X

[half harness]

after an eternity of figuring out why passkeys did not work on my (android - samsung) phone (the "setup passkey" button just didn't do anything but freeze the screen for a split second), I figured it out

Google Chrome had to be installed 🥲

you don't even have to set up chrome or anything

it just needs to be there

welp
just gonna leave this here in case someone else has chrome uninstalled

don't know why that's a requirement though

[ornate nimbus]

What the hell is string manipulation

And codeglance pro

[wind patio]

codeglance basically gives you the same minimap vscode does

string manipulation gives you a variety of options for selected text:

[ornate nimbus]

Damnnn that's so nice

What about key promoter X?

[wind patio]

if you click a thing manually with your mouse, such as 'build', if there's a keybind for it, it shows you what you could've pressed instead

[potent nest]

though it sadly only promotes the stuff that is easy to do with your mouse anyway. The really powerful things can't be really promoted because there's no equivalent operation

But IntelliJ has the Productivity Guide where you can see which feature you're using how much (and which one you don't!)

this is what it looks like

[wind patio]

well, remembering a shortcut is still faster than navigating with your mouse

[potent nest]

yeah but for example syntax aware selection is what really speeds up your coding (at least for me)

[wind patio]

that's like double-clicking a part of text?

or CTRL (+ shift) + W (default)?

[potent nest]

no, it's more powerful than that

here's a quick example how it extends the selection depending on the syntactical structure

[wind patio]

yeah, I'm aware of that, been using this a lot lot

[potent nest]

It's probably one of my favorite features together with Alt + J

[wind patio]

another cool IJ thing is CTRL + Right click

(though maybe that's rainbow brackets feature, I'm not sure)

[ornate nimbus]

That's actually so nice wtf

I feel like I'm not using any of the features that intellij or my plugins have

[sly sonnet]

is there a way to hide that selection?

[crude cloud]

esc

[ornate nimbus]

What are some other plugins you would recommend other than the ones previously mentioned

[crude cloud]

Nyan cat progress bar

system critical

[wind patio]

usually depends what you need or like, other ones I use is jsondiff, One Dark Theme, Grep Console, SonarLint, CSV Editor, Extra ToolWindow Colorful Icons

[distant sun]

What does it do? I assume the commit message is from another plugin

[crude cloud]

default git plugin

[wind patio]

um, no, it's the block marking

the inline messages are from git

[ornate nimbus]

What's that

[crude cloud]

yeah I was talking about the commit message lol

[crude cloud]

it makes progress bars nyan cat

[wind patio]

I meant to reply to gab

[ornate nimbus]

Ohh I used to have that

I think I know you from somewhere

Are you ehh

Argentinian?

[crude cloud]

eyeah

[ornate nimbus]

I think I unfortunately remember you

[slate elk]

        double totalChances = droptable.values().stream().mapToDouble(Double::doubleValue).sum();
        double randomChance = new Random().nextDouble() * totalChances;
        double currentSum = 0;
        DropItem closestItem = null;
        double minDifference = Double.MAX_VALUE;
        for (Map.Entry<DropItem, Double> entry : droptable.entrySet()) {
            currentSum += entry.getValue();
            double difference = Math.abs(randomChance - currentSum);
            if (difference < minDifference) {
                closestItem = entry.getKey();
                minDifference = difference;
            }
        }
        return closestItem;
    }

i feel like it doesnt work currectly

[ornate nimbus]

What doesn't work

[pastel imp]

I feel like she doesn't love me.

now, any good person would ask "why doesn't she love you?" or "why do you feel that?"

anyways, be specific xd, a lot can not work

[distant sun]

Yeah and what does it do?

[potent nest]

I hope you're not really creating a new random instance whenever you call that code

[pastel imp]

💀

I don't even understand what that code is supposed to do

[brittle leaf]

id assume converting a drop table into something you can actually use a random value to get from

converting the chances into like a stacking value composition,

you end up with values like
0.5
0.8
1
and youd going through the list from lowest chance to highest chance and seeing if the random value is bigger

the values would only be different then their chances if theres more or less then 100% chance total for all items in said drop table

doing the composition that way means you dont have to input a single value between 0 and 1 and end up getting something from the droptable list

[pastel imp]

uhm random question, what's a good framework/library to use for a very fast rest api? In terms of latency, requests per second, etc. Performance in general

[potent nest]

that's extremely hard to tell and depending on where the data comes from, the framework might not even matter at all

[wind patio]

well when screen-sharing with colleagues, it's easier to mark the block of code you're refering to

than saying 'uh yeah it's the if statement at the line 175 and the end at 189'

not a big life-saver but still

[slate elk]

Like it does work

But I feel that I wrote the code not in right way

Since the chances seem not work

Like low chance items appear pretty often

Which is weird

[slate elk]

I call it couple of times only …

[potent nest]

yeah every time you call that code

[slate elk]

Well yeah

But still it doesn’t work as I plan it on paper

Like not really paper as it was in my head lol

[potent nest]

I don't know what you're trying to achieve

but you should reuse a random instance

or just use ThreadLocalRandom

also, you probably want to check out https://stackoverflow.com/a/6409791/7137402

[slate elk]

I see

Hmm maybe I’ll change not to be really random

What do u think about it

Let’s say we have a lootFactory which uses the sum and just pushes next number every time that way

I’ll make map that stacks the num of each item

As time when it should appear and then

Random won’t be random

Like random doesn’t exist it probably uses system time or something

To return me a diff num every time

😂

[potent nest]

what

[slate elk]

{a2,b4,c6} a=2 b=6 c=12

[potent nest]

just use the stackoverflow code smh

[pastel imp]

Technically, going to make a request to another api and parse it, so that alone takes around 100ms and I am gonna use redis for caching for the auth keys

[agile galleon]

Just saying, if you need fast data access don't use rest apis?

Imo the fastest json file served wouldn't be much faster using Rust than Scratch

[pastel imp]

there's no other option, I am doing something similar to analyse (not metrics though), the mc plugin communicates and sends data to my webserver... and since it's public, using websockets or whatever is not an option.

kinda going to have to handle a lot of requests per second though

[agile galleon]

Why are websockets not an option

[pastel imp]

it's for a public project and to my knowledge websockets require extra setup and well, shouldn't be used for these things?

it's not for private use.

• it requires for the user to open a port

so, yeah, unsure what other options I have

[ornate nimbus]

trust me she does

i asked her

[half harness]

have you tested any yet?
I feel like popular rest apis really shouldn't have any noticeable overhead

even if it does take like >1ms, if it's a large library it probably has taken performance into account, so latency should be like 99% uncontrollable by the server software

I haven't made a rest api in java before 🥲 so I can't really say much

[half harness]

having an http server also requires opening a port

from the user perspective, the amount of setup should be the same, if not less for using a websocket

[cinder flare]

not if you're hosting the web server and the clients just have to send the data lol

keeping websocket sessions open is a pain, it's not really worth the overhead

[half harness]

oh

wait wdym?

[cinder flare]

just use any rest api framework, it basically doesn't matter, you'll be constrained by data storage no matter what

[agile galleon]

@pastel imp Tebex for example, which has pretty quick execution, just sends a GET requests every 10 seconds

[cinder flare]

good old polling

[pastel imp]

the user doesn't require opening a port, they only send requests to a webserver, they don't receive any nor host a server.

[pastel imp]

the plugin sends the request to tebex or the other way?

[agile galleon]

yes

the other way wouldnt really work

[pastel imp]

true lol

either way gonna have to handle like 100 requests per second minimum

[half harness]

then you don't need a port for websockets either

only the server of the websocket needs the port open

[pastel imp]

but aren't websockets tricky to keep open + "less secure"? Not that educated in websocket tbh

don't they require some type of password/auth?

[half harness]

there's wss:// instead of ws:// - websocket secure which I assume is similar to http and https
as for tricky to keep open, that's what Spooky Star said, I asked wdym but got no response 🥲 so I'm not really sure on that either

but password/auth is not required

afaik

[pastel imp]

I can still have some type of api key though right?

[half harness]

yeah

i think?

[agile galleon]

websockets are prone to just shitting themselves

[distant sun]

is that even a lot?

[half harness]

I assume star has more experience though so take this into account, even if he didn't explain further 🥲

[agile galleon]

so having an instance just send a request every 10 seconds and split the requests onto multiple instances via a loadbalancer, you should be good to go

[pastel imp]

that's low balling it and assuming it doesn't get popular, it can easily got to the thousands per second if it blows up lmao

[agile galleon]

how about you first tell us for what exactly you need all those requests

[pastel imp]

sadly can't do this in theory, I mean, I can for the not "real-time" mode of the service, but for the real-time mode, a request needs to be sent on every message sent in the chat. Sending the requests on bulk would only work for "Assistance Mode"

[agile galleon]

for every message?

[distant sun]

sending a request for each message sounds like a bad idea?

[half harness]

well I guess that answers your question

[pastel imp]

it is a bad idea

[agile galleon]

yeah not exactly

[half harness]

why is it a bad idea?

[agile galleon]

why do you need a request for every message?

[half harness]

depending on the usecase

[distant sun]

metrics

[pastel imp]

actually no

[agile galleon]

no that would be too stupid

[distant sun]

just send the data every x seconds or when it reaches a certain threshold and that should be fine

[pastel imp]

I said analyse as an example since they are similar in the way it works, but working on an AI Moderation system/assistance. For the assistance mode, this would be fine, to send in bulk every few seconds, but for real-time, each message would have to be checked asap and return a response to know if the message should be sent in chat or not. from what I have seen it would delay messages around 80-140ms which isn't that noticeable.

[pastel imp]

^^

[half harness]

o is this gonna be a public plugin?

[pastel imp]

it's a tricky challange, since you have to find the middle ground for UX and at the same time not blow up my webserver lol

[pastel imp]

more like service, similar to analyse or craftbench.ai (formely Minevision).

but it's not going to be solely minecraft focused.

[cinder flare]

having it wait to send the message is not a good idea

it should just check messages async after they're sent and remove them if they're not allowed

[agile galleon]

yeah

[cinder flare]

if your service goes down for whatever reason, people just won't be able to send messages anymore

[pastel imp]

how do you want to remove a message in a minecraft chat?

💀

[half harness]

u can remove signed messages

[cinder flare]

send a lot of blank lines?

you can never really remove anything technically

[distant sun]

yeah well, you did not mention this part, you said "analyse" which simply accepts post requests with data

[half harness]

theres a packet

[pastel imp]

good point.

[cinder flare]

most servers don't do signed messages

[half harness]

true-

[pastel imp]

true

[cinder flare]

and even then, same thing as discord

the clients can just decide to not

[half harness]

also true

but i feel like less true

but true

[pastel imp]

either way, "real-time" mode would be impossible in that case

[cinder flare]

moral of the story, literally any good REST api framework will be able to handle thousands of requests a second easily with a fair bit of resources

Django, FastAPI, Laravel, Spring, ASP.NET, anything

[agile galleon]

i believe the bottleneck would become the moderation ai

[cinder flare]

^

was just about to write that lol

[pastel imp]

that part is covered, working quite decently

[distant sun]

cool

[cinder flare]

if you're really worried, write it in Rust or something lol, that shit'll be lightning

[distant sun]

fast++

[pastel imp]

xD

[cinder flare]

https://github.com/http-rs/tide

here's a cute one I personally liked

[pastel imp]

hell that reminds me of that one time like 3-4 years ago where people were using skript as a backend 💀

[agile galleon]

can you please throw thousands of messages at it and send the results here?

[pastel imp]

where would I get thousands of messages xD

[agile galleon]

random generator bruh?

[distant sun]

what has that anything to do with rust

[agile galleon]

you have a dictionary and a brain that can do programmer things

[pastel imp]

oh nothing, just popped in my mind suddenly while speaking about backends

[distant sun]

from the data you used to train it

[pastel imp]

good point

[cinder flare]

mmmm overfitting

[pastel imp]

true

I mean, it still sucks in a few things

fking mod

(auto mod didn't let me send the msg)

[agile galleon]

so lets see if it shits itself

[pastel imp]

like it doesn't really recognize "noob" or the 3 letters used to tell someone to yeah, RIP

but it does handle stuff like

"shit, you are right"

[distant sun]

doing pretty good, I see

[agile galleon]

ping me when you let it moderate a thousand messages a second pls

[pastel imp]

gotta make a system to make it more compact for that

[agile galleon]

what

[pastel imp]

right now it generates a json with some extra data

so it would be a nightmare to read

[cinder flare]

OLAP db time

[cerulean ibex]

"Lightning"? 😭 quarkus is faster by like 70%

[cinder flare]

i mean, source? lol

[pastel imp]

what's OLAP?

[cinder flare]

idrc though, there's not a lot of speed difference in web frameworks like this

[cinder flare]

https://www.google.com/search?q=OLAP&rlz=1C1VDKB_enUS1045US1045&ie=UTF-8

https://clickhouse.com/

[pastel imp]

bruh

.-.

barry needs a mod ai

[cinder flare]

yeah look into clickhouse fr though, shit is so good at storing that kind of data

[pastel imp]

will give it a check, thanks

I am also doing tests to compare this with using something like fine tuning an openai model, turbo models are awesome and from the tests I did are decently better than my current one but it would be way more costly to do it.

[agile galleon]

how much are you planning to charge?

[pastel imp]

tbf, no fking idea. I think the plans will be based on monthly requests. But you can link as many servers as you like, and I plan on adding support for discord servers too.

Right now, I am in a dilema on if I should do like Minevision and make it based on a discord bot + kofi for starters, then move to a website or if I should just go with a web app directly, which would require much more time, and knowledge since I have no experience with web apps lol but have a lot with discord bots.

So quite unsure on that side on how I should proceed. I am going to begin trials on 2 servers I work for whenever I have the web api set up.

[agile galleon]

A Discord bot works for Minevision because Discord is an easy way to exchange prompts and return images, like Midjourney did. If you want the whole thing to also work on Minecraft servers and on other platforms, you shouldn't use a Discord bot

You can still use KoFi, but I've had a few issues with it and it's not really built for that

You can easily achieve a monthly subscription with stripe or Gumroad for example

thats just my opinion though

having a discord bot as your interface will shoot you in the knee in the future

[pastel imp]

that's why I am still having my doubts, although the system should be built to support moving to web flawlessly, since the discord bot would only be an interface.

[pastel imp]

Also, do you mind sharing what issues you had?

[agile galleon]

gonna. be. a. pain. in. the. butt.

[pastel imp]

gonna be a pain in the butt either way since I have near zero experience building web apps xd, so chances something goes wrong are very similar

[agile galleon]

an issue i had is kofi saying that the subscription expired while the customer only cancelled yesterday and the subscription should still be available until the end

[agile galleon]

either you do it now, or you do it later while also spending time refining a UI you will be removing either way and designing a system around modular UIs

also as I said, kofi isnt built for such a thing

[pastel imp]

I think at the end, I know that I should just do a web app, but my lack of experience scares me of fking up and the comfort I have with discord bots works as an escape for me

[agile galleon]

youll have to do it either way?

[pastel imp]

fighting a mind war lmao

[agile galleon]

honestly if you go with Laravel you will save much time

[pastel imp]

yeah I suppose, but meanwhile I could already be testing the waters

[pastel imp]

that's what I am leaning into

[cinder flare]

Laravel 😌

if you're not familiar with frontend shit, you can get pretty far with just Blade templates

[agile galleon]

yeah

[cinder flare]

especially for like, a basic config thing for the service

[agile galleon]

doesnt have to look pretty

[pastel imp]

define frontend shit

[cinder flare]

javascript

React/Vue/Svelte

[pastel imp]

I am quite decently comfortable with html and css, javascript I suck lmao

[pastel imp]

only one I have used is Svelte

[cinder flare]

you can use Laravel/Inertia with Svelte easily

[pastel imp]

although react ecosystem do be poggers

[cinder flare]

it's kind of annoying to get it SSR'd, but if you're just doing a basic config site it shouldn't be that bad

[pastel imp]

yeah, got told so by Charlie xD

[cinder flare]

you can use Blade templates for the marketing part if you need

[agile galleon]

yes

[agile galleon]

not that required though

[cinder flare]

it is for marketing/public facing parts

unless you want to never get any SEO and not show up on google lol

[agile galleon]

the text is always static, isnt it?

[cinder flare]

huh?

[agile galleon]

wat

maybe im stupid

oh shit yeah

[cinder flare]

in a normal SPA, the html is empty, it just mounts a javascript script that makes all the content

that's why you SSR, so that the first initial page load has all the shit on it

[agile galleon]

i was stupid there for a sec

[pastel imp]

xD

Was thinking on using Laravel Spark if I went with Laravel but it sadly only supports Stripe...

[agile galleon]

https://www.udemy.com/course/learn-laravel-with-inertiajs-and-svelte/

[pastel imp]

Could Tebex be an option? Don't they have Tebex Checkout or whatever it's called?

[agile galleon]

use Stripe?

[cinder flare]

Tebex is more for game servers

[agile galleon]

like stripe is the thing you'd use

[cinder flare]

use something like Shopify or Lemon Squeezy if you want broad support and an easy API

[agile galleon]

imho

[cinder flare]

in both of those, you could just make a checkout link, redirect the user to it, then receive a webhook when the payment goes through

[cinder flare]

PayPal support is the biggest downside here

[pastel imp]

no support for PayPal as said above and we all know big chunk of minecraft audience uses paypal

[agile galleon]

ah crap minecraftttttt

[pastel imp]

but don't they have Tebex Checkout which is supposed to be for everything?

[cinder flare]

idk but your fees are most likely going to be higher than just doing your own thing

especially if you don't plan on using their webstore

[cerulean ibex]

Tech empower

[agile galleon]

I'll watch the 7minute segment about SSR and tell ya how it works

[cinder flare]

okay, well idk how much I trust that, but 62,000 requests per second seems pretty all right to me

I guess they could use actix-http for 500,000 requests per second lol

[agile galleon]

or just a load balancer

[cinder flare]

i severely doubt the rest layer will be the bottleneck

[pastel imp]

btw is this for someone already familiar with Laravel or straight from scratch?

[cinder flare]

I would not buy a course lmao

[agile galleon]

i believe this is for somebody already familiar

[cinder flare]

Just follow the Laravel breeze tutorial

super easy stuff, it can scaffold a whole project with auth and everything with Svelte iirc

might just be React/Vue, but it's pretty easy to swap out

[agile galleon]

the tutorials are good etc and youtube too but this course has served me exceptionally well: ~~https://www.udemy.com/course/lalavel-beginner-fundamentals/~~

[cerulean ibex]

Yeah thats what i was thinking

[agile galleon]

(only doing this because i dont pay for them)

[cerulean ibex]

Actix or axum are more lighting

[cinder flare]

yeah lol, kind of a weird ad

[pastel imp]

just reminding you, you are speaking with someone with 0 knowledge on these things, max I have done on the web is static websites, I am more of a frontend dev

[agile galleon]

yeah the one i sent above is straight for beginners

[agile galleon]

its not an ad

[pastel imp]

eyo, wanna share secret?

[cerulean ibex]

Or i think as every rust nerd says, blazingly fast

[cinder flare]

it... basically is? "here buy this coursee it's really good only $16"

[cinder flare]

https://laravel.com/docs/10.x/starter-kits

[agile galleon]

i didnt say you should buy it, only said courses like that one have served me well in comparison to the laravel tutorials and countless youtube videos

but yes it could be seen as an ad

i dont intend for it though

[pastel imp]

yeah already saw this, although was quite lost in it lmao

[cinder flare]

Just do Breeze & Blade

[pastel imp]

welp, will have to check this out tomorrow, gotta head to bed rn

thanks though for help in both things

I will hurt you

[ornate nimbus]

Will you hurt every rust user

D:

[prisma wave]

if necessary

[slate elk]

here what i mean

i will always have on my hand the existing possible drops

everytime an item will be token out i will re generate them back to list

instead i wont use double anymore for lower precentages its dumb

ill shuffle everytime and take [0] and ill just add the missing item using its ID

Actually no need shuffle

ill just make work in loops

when i add something to list it goes always to be last position right?

[potent nest]

Yes

But that’s not really random

But I still don’t know why you don’t just use the NavigableMap approach

[slate elk]

really random does no exist lets be honest

it will be random for users

because they wont know whats next ;p

and it will keep things in right balance

my team senior dev uses white theme intellij

[pastel imp]

[final scroll]

I have this code for storing a value in a MySQL database.

private static final String INSERTION_QUERY = "INSERT INTO FooBar(id, data) VALUES (?, ?) ON DUPLICATE KEY UPDATE data = VALUES(data)"

//...

String id = structure.getUUID().toString();
String serialized = new String(ByteSerializer.SERIALIZABLE.serialize(structure));

PreparedStatement pstmt = connection.prepareStatement(INSERTION_QUERY);
pstmt.setString(1, id);
pstmt.setString(2, serialized);

pstmt.execute();
pstmt.close();

I also have this code for getting the value in the database.

private static final String SELECTOR_QUERY = "SELECT data FROM FooBar WHERE id = ?";

//...

String id = uuid.toString();

PreparedStatement pstmt = connection.prepareStatement(SELECTOR_QUERY);
pstmt.setString(1, id);

ResultSet set = pstmt.executeQuery();
String value = !set.next() ? null : set.getString("data");

set.close();
pstmt.close();

But I get the following error when loading the data and I do not understand why java.sql.SQLException: Column 'data' not found.

[agile galleon]

Well does your database have the table?

[final scroll]

When I do it manually all works fine

So yes, the table is there

[potent nest]

have you tried to use a debugger?

[slate elk]

I mean I think it’s better then random

Because random can hit twice same@number

Or never something

[potent nest]

also data is highlighted there, maybe it's a keyword in your sql dialect? If so, try putting it in ``

[slate elk]

That way I know once 100 generates there will be 1 lucky player 😉

[final scroll]

If I put the data in '' I get this. The correct value is display if there are no '' :/

[potent nest]

well if you do whatever you're doing right now, you should just probably use a Queue instead of a List, but then you still have the issue that you always have the same order

[potent nest]

``, not '' or ""

[final scroll]

Like in the SQL software? Because everything works fine there. It is the Java code that is the problem.

[potent nest]

no, in Java

[final scroll]

Ahh, I see. Sadly that did nothing though.

[final scroll]

wait no, it did

Thank you :)

[slate elk]

It’s ok even if same order

How should I queue

The thing is there will be couple queues

For category and sub item

Now it will be appeared within 10 other items

It doesn’t really matter because users will do 600 of those every hour

[potent nest]

Players figure out stuff like that faster than you might think

[potent nest]

The same you do as with the list, but removing the first element from an ArrayList is far more expensive than removing it from an implementation that is meant to be used as queue

[inner umbra]

Set<Object> objects -> objects.get(Random.nextInt(objects.length-1))

[slate elk]

i dont think because the size of the tables are around 200 options

now u can multiplie those options by 100

which gives me 200,000

i think too big list lol

[potent nest]

yeah that might be fine then

but then you really shouldn't remove the first element from an ArrayList lmao

[slate elk]

i wont remove any element

i will just init the size

and then do if (size > pos){ +1 } else { 0 }...

[potent nest]

yeah that's fine then

[slate elk]

yeah the amount of things players can get is so huge actually

some items have different stats

its rng in rng in rng in rng lol

dunno how i will do wiki haha

[slate elk]

nah random is bad

it works like shit from some reason

and doesnt feel like the 0.5% is 0.5%

[inner umbra]

I create a map of items with their chance... Run random and collect items above the number. Then I choose a random item from the collected.

[potent nest]

I mean that certainly is an issue on your side, as it works as guaranteed by its specification

[slate elk]

it sounds also pretty good but random isnt really random dont u think so?

at the moment i do simillar thing

i have sum of all options it doesnt go by 0-100

it goes by amount of options which is around couple of thousands

and i reterive the most close option

[potent nest]

if random isn't really random, what are you doing to make it actually random?

[wind patio]

in programming there's no actual 'random', just 'random'-enough or pseudo-random

[crude cloud]

there's the dn random algorithm

[wind patio]

dn?

[pastel imp]

jokes on you, did a coinflip once using the Random class, somehow a guy won it 16x in a row lmao

either he's a luckly mf or idk

that's like 0.001526% of happening

[potent nest]

I mean that's just how probability works

[wind patio]

true

[inner umbra]

50% chance every time

[crude cloud]

yeah, 16 times in a row adding up to a whopping ~0.0015% for the entire sequence

[tawny crest]

"a better gaming chair"

[slate elk]

yes

some random algorithm depends on system time , or other thing that updates consteantly

and then you get some sort of random

but in general random class is really bad i think

it doesnt work like random at all

int randomnum = (int)Math.floor(Math.random()*(max-min+1)+min);

i think Mah.random is better

then Random

[potent nest]

man you really have no clue what you're talking about

Math.random() uses a global instance of Random

[wind patio]

Lol

Blud be bluddin

[wind patio]

Gonna repeat what SirYwell said, but yeah, you use the Random class when you, for ex. want each class instance to have a different seed for it, Math.random() just uses a static instance of Random class itself, and you're kinda limited to the one method Math class provides which returns double. If you use Random itself you can use next, nextInt, nextLong, nextBoolean, etc.

What

Shocker

Its like this is somewhat universal between coding languages

You'd be shocked that javascript also has Math.random

Guns are illegal in minecraft

Banned

https://apexminecrafthosting.com/minecraft-gun-ban/

Yea yeah I think its only for the servers

[inner umbra]

Mods, plugins etc... can't be removed by mojang cause it's not their code. But servers can be blacklisted that have these banned resources... you could just remove the ban code from the client though.

[crude cloud]

they can send you a takedown request if the plugin/mod does not align with their community guidelines

[inner umbra]

They have no legal standing to do so. As long as you aren't using their assests you're fine.

[wintry plinth]

Well.. they can, because its their game that you're modding. They'd only need to send a takedown to like CurseForge for example

[prisma wave]

Yeah lol they have every right to do something like that

anyone able to help me with this im trying to use a left click requirement

      requirements:
        anything_here:
          type: has item
          material: QUARTZ
          amount: 50```

[prisma wave]

#general-plugins

[past eagle]

Java docs/spigot forums has it, click listener I believe, did you check over there?

[inner umbra]

Damn doing some micro optimization for my bitcoin mining software...
Just doing String blockheader = job.version + job.previous_hash + hexRoot + job.time + job.bits + nonce; drops the amount of calculations from 100+ mh/s to 13 mh/s
Also tested with StringBuilder and had the same performance issue.

Any ideas on how to optimize this? Literally just appending variables into a string.

Seems like collecting the values from the variables is what causes the strain on performance...
String blockheader = "Test1" + "Test2" + "Test3" + "Test4" + "Test5" + "Test6"; works fine.

[potent nest]

Well the latter will compile to a single string

But generally, string concatenation has a few problems: you need to allocate memory , you need to create a string from most non-string objects before, you need to convert numbers into a string representation…

But e.g. converting an integer to a hex string should be somewhat faster than decimal

[inner umbra]

Well... all of those variables are strings lol

[potent nest]

Then it’s most likely just memory overhead

[prisma wave]

as always, run a profiler before trying to make any assumptions about performance

[inner umbra]

I was adding in line by line to see where the most strain from the calculation comes from. So I narrowed it to that to start with.

That then hex then hash.

[potent nest]

Changing code is a bad idea when tracking down performance issues

Just use a profiler as bm said

[inner umbra]

Long.toHexString() also takes some time but not many better methods then that.

I can do both ways. It's only a few lines of code so there isn't a lot of code to profile lol

Also got and increase in calculation by not checking an atomicboolean and just doing while(true) {

[potent nest]

You‘d be surprised by how many things can go wrong this way

[inner umbra]

🤷 working out fine for me.

I'll probably pre concat the string when the job is found and add the nonce when needed.

[inner umbra]

Yeah having the variables appended when the job is found makes about a 10 mh/s difference.

String blockheader = preheader + nonce; is still taking a good 70+ mh/s off the total calculations it can do before hex/hash

string.concat(String) is faster then +
String blockheader = preheader.concat(nonce); jumped up to 43 mh/s

Getting an additional 2 mh/s as the result 😉

100+ kH/s on my raspberry pi

[prisma wave]

i believe this will vary a LOT

https://www.baeldung.com/java-string-concatenation-methods

[inner umbra]

Well at the moment its varying in my favor lol

[slate elk]

It’s on Java ?

[potent nest]

Yes

[drifting aspen]

Just why would you write a CPU miner in Java?

[snow oriole]

can someone explain how gradient work ?

[inner umbra]

Cause I can.

[potent nest]

Why not?

[ocean quartz]

"because java slow" - them, probably

[prisma wave]

i meannnn

there are some cases when that statement is actually meaningful

[drifting aspen]

It's definitely slow for making a CPU Bitcoin miner

[crude cloud]

bro hasn't heard of hotspot

[drifting aspen]

:/

I have

[inner umbra]

Yeah Java isn't the fastest language for a bitcoin miner. But if you look for one there aren't many if any. And I like to make my own things and I know Java more then c so 🤷

[blissful sluice]

Could try something like rust, or i imagine go is even faster than java

[inner umbra]

They wouldn't be faster then c. At least in this case.
(That could or might have already changed though)

[prisma wave]

rust can outperform c under the right circumstances

[blissful sluice]

you said know you more Java than C, so I was trying to find a middle ground :p

i find rust so bulky sometimes

like, with the whole crates thing

[inner umbra]

Honestly I should learn c and stem to other languages from there. Been limiting myself to Java for years.

[blissful sluice]

Maybe try working down, rather than falling down

[inner umbra]

Nah. I go straight for my goals lol

[blissful sluice]

Going from not managing your memory at all to managing every spare bit sounds... painful

[inner umbra]

I usually try to keep in mind what I'm saving to memory anyways

[prisma wave]

how so?

[drifting aspen]

Understandable

[blissful sluice]

you need a use crates for basically everything meaningful, at least that's what it seems like

[prisma wave]

maybe

[blissful sluice]

async- need a crate
decent http stuff- need a crate
json stuff- need a crate

[prisma wave]

but it's not like theyre hard to use

java doesnt have json built in either

and it only recently got decent http

[drifting aspen]

Yeah and?

[prisma wave]

it's the "npm philosophy" i guess lol

[blissful sluice]

laughs in leftpad

[drifting aspen]

Literally one command to install the relevant crate

Or tbh, the IDE might even install it for you

[prisma wave]

yeah i should clarify, the npm philosophy but not shit

[drifting aspen]

Except no shitty node_modules folder

[blissful sluice]

Idk I just don't like that the sdk doesn't come with some of these imo basic tools

[prisma wave]

mmm

[prisma wave]

as i said, you could say the same about java up until very recently

[blissful sluice]

yeah but it's Java, nobody expects it to be good

:p

[prisma wave]

😭

[blissful sluice]

using json and building CLI applications in go is fucking amazeballs

[drifting aspen]

I think maybe the goal of the authors was to keep the executable as small as possible?

[prisma wave]

technically you need a package for json in go too

i am all for hating on rust but this doesnt seem like a great way to direct the hatred

[blissful sluice]

wot

[prisma wave]

import "encoding/json"

realistically how is this different to adding a single line to the cargo file?

[blissful sluice]

because it's internal, not external

[prisma wave]

if you cant tell the difference, does it matter?

[blissful sluice]

imo yes

not to mention, go's json support is just generally a whole level of its own

[prisma wave]

maybe you're right

but i think as long as the 3rd party libraries are equally high quality it doesnt matter too much

a lot of languages have small sdks

[blissful sluice]

and like, concurrency in rust... gotta use tokio, there's another 3rd party dependency

decent flags system for commands? pretty sure that's another crate

go, flag support is native
concurrency too, with their whole channels thing (at least that's what I understand that to be for)

[prisma wave]

you're correct

i suppose the justification would be that it's better to let the community decide what works best rather than mandating a single "perfect" way of doing things

after all, go is not without its flaws

[blissful sluice]

go's need to constantly define and check for errors is kinda annoying

a lot of the time half the code just ends up being

if err != nil {
  lot.Fatal(err)
}

or some variation of that, repeated every few lines

[prisma wave]

yup

go error handling is potentially the worst thing in all of programming in the 21st century

[blissful sluice]

fair, but at the same time when you end up with libraries like reqwest (or whatever it's called), tokio and serde as the de facto standards, you're not really deciding anymore, you're just using 3rd party libraries that have become so big due to the lack of their existence in the sdk itself

[potent nest]

Why?

In most cases, it comes down to whether someone knows what they‘re doing, the language is rather a secondary factor

[prisma wave]

they are popular but theyre far from standards - there are plenty other options for async libraries for example

[blissful sluice]

sometimes it's not terrible, like when I can do:

if err := doSomething(); err != nil {
  log.Fatal(err) // or whatever
}

[prisma wave]

and i still think that's better than the sdk designers trying to get it right first-time, failing, and then being stuck with legacy code in the sdk for years

[prisma wave]

yeah that still sucks

you also need to return in most cases or you end up with further errors later on

at least 3 lines of code per failure case is unacceptable

even checked exceptions are better

[drifting aspen]

God I hate checked exceptions

[blissful sluice]

i'd rather just have default behaviour be some sort of log/stderr/panic thing, for those smaller applications where doing anything more than that isn't necessary

[potent nest]

Checked exceptions are an extremely powerful concept

[prisma wave]

oh yeah theyre overhated

[potent nest]

But their integration in the language could definitely be better

[prisma wave]

but this is just a runtime exception system like java/kotlin has

[blissful sluice]

eh ig

[prisma wave]

anyway conclusion is that monadic errors > everything

[blissful sluice]

I also hate Go's variable system sometimes, mostly as a result of this error checking system

cus you can end up with 2 different variable states which means you either have to do hacky shit to assign the variables

one feature of go that i recently discovered which actually seems pretty powerful is go's return system

if you name your return types with variables, you can assign to them and just return at the end, rather than return x, y

[prisma wave]

oh i dont like that at all

it stinks of the single return point antipattern

yes lets introduce more mutable variables all the time that will be great

[blissful sluice]

hmm ig

i imagine there's some places where that's useful tho

[prisma wave]

very few

its definitely not something that should be encouraged imo

[blissful sluice]

imma say something that seems really dumb:

I don't actually understand async stuff, especially as frequently used in MC

Like, you're almost always going to end up joining onto the main thread anyway, so what's the point?

[prisma wave]

you're almost always going to end up joining onto the main thread anyway
not if you're smart

[blissful sluice]

async DB queries especially

[prisma wave]

ok, perfect example

let's say a query takes 200ms, so 4 ticks

doing that on main thread and joining means the whole server spends 4 ticks waiting for the query and doing nothing else

doing it on another thread and using a callback (or similar mechanism) means the server can be doing other things while it's waiting

if you're joining regularly you're doing something wrong

[blissful sluice]

fair chance i'm doing something wrong, tbf

[prisma wave]

it certainly sounds like it

[blissful sluice]

but in my defence, i'm not the only one

[prisma wave]

far from it

the spigot community is notoriously incompetent

cuz everyone learned from shitty yt tutorials and never learned how to actually program

[blissful sluice]

raises hand in shame

[prisma wave]

not too late to fix it!

i was the same

kinda

[blissful sluice]

My latest question in #development message is the result of this

i'm trying to learn, but it's so hard trying to wrap my head around these things

I learn best by doing and by seeing how others do things, but because of the nature of my projects being very... particular, there's not a massive amount of good quality references

[prisma wave]

i dont think theres an objectively right answer to that question, it's quite subjective

personally i try to stick to POJOs for the data and then have repository types that handle the actual reading & writing

like Spring does

[blissful sluice]

Like i've been sitting here on and off for the past few months/year doing those JetBrains Academy lesson/tutorial/project things, and I get kinda bored pretty quickly cus most of the stuff I know, and the projects are simple enough that they aren't really helping me

that's not quite what I meant, i don't think

[prisma wave]

is it not?

could you give an example?

[blissful sluice]

I was more talking about relationships with other objects, like say for the sake of argument in a factions/towny type thing:

Should the Player/User/whatever object hold a reference to their Faction/Town or should there be some sort of map, or both?

[prisma wave]

i think it depends, really

i prefer to go for hard references but theyre not always achievable, often if you have bidirectional references then it can get messed up

and you get a toString that StackOverflows

but hard reference unless you need a map, seems like a good approach

[blissful sluice]

same question for the DB representation, though I think the answer for DBs is a bit simpler:

Even though it's one to many, should it be a reference table with a composite PK (e.g. faction_guid, player_guid)

or just a coloumn in the player table: faction_guid

for DB purposes I'm always inclined to go for the latter, but that type of thing tends to result in me having circular relations:

a player with a faction, and a faction with a player (e.g. faction_leader)

[prisma wave]

you dont need a reference table for one to many

only many to many

[blissful sluice]

that's what i assumed

I've thought about adding a CS degree onto my list of degrees in the hopes it'd maybe teach me even half this sorta shit, but from what I've seen/heard, CS degrees rarely teach actual programming

at least this sort of programming; most of it seems to be web dev or python or the like

[steel heart]

lol yet today this is true

[prisma wave]

depends on the degree a lot, mine is a healthy mix of theory and practical so far.

[prisma wave]

that sounds more like software engineering than CS

[prisma wave]

always will be

[blissful sluice]

not worth the 3 years or 45k if it doesn't teach what i care about, that's 3 years and 45k I could put towards postgrad

[prisma wave]

oh yeah i wouldnt get a degree just to learn relational database design lol

[blissful sluice]

I mean it wouldn't just be that, just program design type shit in general too

[prisma wave]

yeah all of that can be self taught with enough time & effort though

[blissful sluice]

exactly why i haven't added that degree to my list- it's only my backup if both my other 2 fall through

[wind patio]

Whats the topic, I'm a programming genius and I'll answer your question

[prisma wave]

what is a monad?

[wind patio]

Idk

[blissful sluice]

i've heard of that word, that's about all i know

[prisma wave]

hehe

[blissful sluice]

not that it's relevant, but the other 2 (which I'm planning on learning successively and/or concurrently, depending on where I end up in the next year) are international studies & law

[prisma wave]

2 degrees??

[blissful sluice]

that's just undergrad

if i have the means (financial, motivation, and academic capacity) to do so, i'll probably end up with another 2 postgrad at least (one in each field- international relations and law)

[steel heart]

a monoid in the category of endofunctors 🥲

[prisma wave]

even so, thats still an insane amount

plus an insane amount of debt to go in

[prisma wave]

true

[blissful sluice]

eh only ~100k for the 2 undergrads

bit less, bit more, depending on the exact arrangements

[steel heart]

Sadly had to learn category theory since we use haskell for reasons unreasoned for

[prisma wave]

"only"

why do you need 2?

[prisma wave]

wait you actually learned category theory??

[blissful sluice]

interested in international relations and law

[prisma wave]

thats so unnecessary lol

[steel heart]

Yea we are being taught basic category theory with the classic example of using category set

[blissful sluice]

well, that's just shy of the ~115k no-interest loans the govt give us :p

[prisma wave]

oh thats actually really cool

[prisma wave]

oh damn 🥲

couldnt be uk

even so, it's a hell of a lot of commitment

[prisma wave]

totally unnecessary but it's a very interesting branch of maths

[blissful sluice]

i've got a hell of a lot of time

and nothing better to do with it

[prisma wave]

get a job?

[blissful sluice]

that's a funny idea

[prisma wave]

it is

[blissful sluice]

if things work out with the degrees i'll hopefully end up with a job at DFAT (Australia's State Department/Foreign Ministry) or the UN, or somewhere similar

or if i do really well in my degrees, maybe i stay in academia and continue on to masters etc

that's 3-8 years (depending on configuration) down the line, we'll see what happens then

[blissful sluice]

anyway, do you have any open source projects that deal with databases properly i can take a peak at

[crude cloud]

@prisma wave

what is going on

[prisma wave]

?

[prisma wave]

uhhh https://github.com/knightzmc/vouchers/tree/master/src/main/java/me/bristermitten/vouchers this is kinda old but might help you

the actual implementation is in the persistence package

[blissful sluice]

thanks, will take a peak

[prisma wave]

but its a bit of a mess

[blissful sluice]

That is uh, certainly one way of describing what I'm seeing :p

[prisma wave]

generally though:
https://github.com/knightzmc/vouchers/blob/master/src/main/java/me/bristermitten/vouchers/data/claimbox/ClaimBox.java pojo for the actual data
https://github.com/knightzmc/vouchers/blob/master/src/main/java/me/bristermitten/vouchers/data/claimbox/persistence/SQLClaimBoxPersistence.java SQL implementation that does all the queries and loading

it's slightly overengineered bc i wanted json support too

[blissful sluice]

overengineered is one of my favourite states :p

[prisma wave]

real

[blissful sluice]

is it really engineered if it isn't overengineered

One thing I love about newer versions of Java, I can now write multiline SQL queries without it looking like a mess

hmm, i notice you don't have a dedicated thread pool for your async stuff

[prisma wave]

yeah i just use the forkjoinpool

frankly im not sure if it's a good idea or not to do that

[blissful sluice]

From what I saw in LuckPerms and in Aikar's IDB, they both created some form of thread pool

suggests maybe not the greatest idea to do that

However, here's my problem:

you can't easily use CompletableFutures in a TaskChain-like manner switching between sync and async unless you have the executors for both handy

[prisma wave]

thats not entirely true

but ive basically never had to do that

but just make the executors constants and ur balling

[blissful sluice]

can't easily do that, at least without static stuff- e.g. an instance method on ur JavaPlugin or using the JavaPlugin#getPlugin/getProvidingPlugin stuff to access main thread

[crude cloud]

this is when you throw in a DI framework and you make your own @ServerThread annotation you can have something like public MyCtor(@ServerThread Executor serverThreadExecutor) and configure your DI setup to bind the main thread executor to an Executor.class annotatedWith ServerThread

[blissful sluice]

but DI framework = more bloat 😦

[crude cloud]

shh no

more engineering

here, have some

[blissful sluice]

i'm the type of person that will try to break down a library and remove all the shit that i don't want/need

[inner umbra]

^^^ except I just code it from scratch lol

[agile galleon]

You're the yapper type ig

[blissful sluice]

it's one of the reasons I have such a hard time settling on a command framework too

[agile galleon]

LAMP ftw

[blissful sluice]

Tried LAMP, it couldn't do everything i needed it to do

or wanted it to do

[agile galleon]

What do you need more?

[blissful sluice]

it was something to do with permissions

[agile galleon]

Wat

You can always check permissions yourself

[blissful sluice]

it was a complicated permissions system on top of the base permissions system

like, think factions permissions type thing

[prisma wave]

can still do it yourself hehe

[blissful sluice]

i wanted to use their resolver system

wait no that wasn't the most important part

the most important part was the ability to optionally consume input as part of a resolver

[agile galleon]

Can you not?

[blissful sluice]

I don't think so at the time

[agile galleon]

What type of resolver?

[blissful sluice]

I wanted to have it so that if the user hadn't provided input, the parameter value would be provided

idk what the deal was, but it wouldn't work

[agile galleon]

I'm confused

[blissful sluice]

wasn't designed to allow it

[agile galleon]

Eh whwatever

[blissful sluice]

I was trying to do something equivalent to ACF's IssuerAwareContext

[agile galleon]

Never used acf, then use that

[blissful sluice]

You may also use registerIssuerAwareContext instead to tell ACF that this resolver is able to resolve without consuming input, by understanding the context of the issuer of the command (such as World, Location, Etc)

A non issuer aware resolver must consume input. Issuer Aware may optionally consume input if supplied, and fallback to context if not.

f you want an Issuer Only resolver, one that always resolves based on Issuer and never consumes input, you may use registerIssuerOnlyContext

that's the description for ACF's parameter resolution system

[prisma wave]

why not just use ACF?

[blissful sluice]

ACF was too complicated in some parts

[agile galleon]

That sounds like legalease lmao

[blissful sluice]

too bulky for what i wanted

[agile galleon]

So you want complicated features but not a framework that has that feature and is accordingly bulky

[blissful sluice]

nah ACF has a bunch of stuff on top of that xD

[agile galleon]

If you want a cf and you can't adjust to any other make it yourself

[blissful sluice]

ain't that big brained

the next on my list of frameworks to look at is Piston by the WorldEdit people

[wind patio]

how yall people have time for this shit

do yall not work fulltime or something

[blissful sluice]

so, i'm looking at this, and i realised you barely managed to avoid my #1 sql-pojo problem:

getting the primary key

[prisma wave]

?

private final UUID owner; primary key

private final UUID id; primary key

[blissful sluice]

yeah, but normally you'd use a long/int auto-increment

[prisma wave]

that doesnt make a huge difference though

[blissful sluice]

especially for relational tables that are all inter-mingling

doesn't it though?

If you've got a bunch of tables all using a uuid foreign key?

[prisma wave]

how is that different to a long foreign key

[blissful sluice]

i mean, size of data for one
and also everyone i read online keeps saying that UUIDs are bad cus of indexing and sorting issues or something

[prisma wave]

i mean, size of data for one
yes but how does that make a practical difference. my code still works, doesnt it? just replace UUID with long

[blissful sluice]

i meant in the database

[prisma wave]

yeah? same thing

[blissful sluice]

efficiency n stuff?

[prisma wave]

just int instead of varchar(36) or whatever

i really dont get what your point is

just change the type

suddenly your #1 problem is solved

[blissful sluice]

you're sacrificing DB efficiency/performance

[prisma wave]

sure but i dont care lol

it's an unfinished plugin that never released

and using UUIDs is infinitely more convenient

[blissful sluice]

that was generic you, not you you

[prisma wave]

sure

but without being rude i really dont see why this is my problem lmao

you know a better approach, so use it

[blissful sluice]

i know the approach I should be using, but i have no idea how to implement it properly xD

[prisma wave]

?

literally
