Basically compile time reflection lol

Oh yeah and good luck figuring out if the compiler throws errors lol

The closest you get in Java on specialization is either inheritance & overriding methods or just a whole separate class on its own (IntStream and Stream<T> are separate classes altogether, if specialization was a thing, they would be just Stream<T> and one Stream<int>)

[hot hull]

How ugly/dumb would it be to have a try catch for NPE as a condition to close the menu :p

[jovial warren]

Lol

Just null check

Ez

[hot hull]

Not my code so it's a fucking mess

[cinder flare]

"Aw, who wrote this crap? This is so confusing!" git blame "Oh, it was me."

[hot hull]

Nah it's not confusing, it's just made in a retarded way because the person didn't know what they were doing

[cinder flare]

Are you fixing it?

[cinder flare]

holy shit copyright Sun from 2006

[quiet depot]

"Better fix that." git blame-someone-else "Starmism <[e-mail]>" 3b3125c4da142e64becd02095a4f1c4b7e2cd9ab

[cinder flare]

😮

bro I wish I had starmism.com and a noreply email for it

[quiet depot]

and I wish I wasn't so stupid that I just blamed it on the person who was originally at blame

[cinder flare]

oh I thought that was from your pov haha

[quiet depot]

noreply emails are overrated

I have a noreply email

and it's the only email i use

i also send emails from it

it usually confuses people because I have to say "please do actually reply to this email, even though it's called noreply"

fun stuff

[cinder flare]

bet you have your own domain and everything 😔

[quiet depot]

https://piggypiglet.me

also got https://p1g.pw

that's mainly for dev stuff tho

[regal gale]

Hello? My question please? 👀

[quiet depot]

go ask in #development thien

[cinder flare]

😑

[quiet depot]

what's the face for

[cinder flare]

i've got zero domains, and you've got two

and one of them is a google thing or something?

[quiet depot]

google thing?

no

p1g.pw points to a link shortener, but I mainly use the domain for dev stuff

projects and shit

google.com is just an example link

[cinder flare]

oh that makes sense

[quiet depot]

used to have 3 domains actually but let the third expire, didn't need it (piggeh.org)

3 isn't even that much

gian has way more

[cinder flare]

😖

[quiet depot]

can you not afford a domain?

[cinder flare]

no lol

[quiet depot]

can't afford $20 a year?

actually you're probably american aren't you

more like $15 for you

[cinder flare]

well with zero income, it is pretty hard to pay recurring fees

[quiet depot]

eh

do you not get money on birthdays or christmas?

[cinder flare]

goes towards paying for uni

[quiet depot]

and you can't spare $20?

[cinder flare]

my parents take it i dunno man

[quiet depot]

have you asked them lol?

[cinder flare]

i do suck at making websites, so maybe it's for the best lol

i mean not about a domain lol

[quiet depot]

a domain is quite important

well at least to me

anyway

students can get a free .me from namecheap for a year

while still a student, renewing is discounted

[cinder flare]

already used it like 3 years ago

[quiet depot]

there's also like 2 other companies on github edu that give free domains to students

[cinder flare]

yeah used the other one

[quiet depot]

then there's also the final option of using your non tech savvy friend's school email

[cinder flare]

pfft haha

[quiet depot]

i've done it before

[cinder flare]

now that is pretty big brain

now all that's left is to think of something to put there!

[quiet depot]

ricardo

[cinder flare]

https://tenor.com/5Mdo.gif

[cinder flare]

oh yea

[heady birch]

Amazing

[quiet depot]

nice style niall

quite modern

[heady birch]

Inspired by the ultimate thymeleaf tutorial

[quiet depot]

wow

[heady birch]

The best software

Every garden centre in the UK is using it

[quiet depot]

was*

was using it

[heady birch]

Lol

[quiet depot]

like 100 years ago

when that styling was acceptable

[hot hull]

Niall

Can you stop using 500 year old website designs

[heady birch]

Programmers these days

[quiet depot]

the dinosaurs will come back if this keeps up

[heady birch]

All they know is nodejs, bootstrap, vue

Talking about bootstrap

What are some cool CSS frameworks?

[quiet depot]

bootstrap

bootstrap is still my favourite but some people use some weird shit called "bulma" aswell

[heady birch]

5 is available

Oh bulma is neat to be honest

[quiet depot]

and some people have just given up on the manual html/css thingo and use vue (which I think basically does everything for you? ngl haven't looked into vue much)

[heady birch]

Neither

Wow, ofcourse a windows 98, XP and 7 css framework exists

[hot hull]

l

[cinder flare]

J

[old wyvern]

That would be useful if we want to selectively load dependencies ig

[quiet depot]

I'd assume the value

[old wyvern]

Ill remove the xml parser since we wont need that now

[cinder flare]

I presume you give it the key and it gives you the value

nice one more level and a new color!

[old wyvern]

Same

altho 9k exp tho

😬

[cinder flare]

awe nice only 3k

[jovial warren]

I think I wanna use a scheduler for ticking at this point lol

screw your sleep method Yugi

it always gets out of sync and doesn't produce accurate timing results

[cinder flare]

👀

[jovial warren]

I think that means I can't do watchdog though

but watchdog seems kinda broken anyway, so not really sad about that lol

https://i.imgur.com/KQCJfhR.png now that's more like it

[static zealot]

Oh did Krypton just hit 20 tps?

[jovial warren]

using a single-threaded SES, yes

tickScheduler.scheduleAtFixedRate({
    val nextTickTime = System.currentTimeMillis() - lastTickTime
    if (nextTickTime > 2000L && lastTickTime - lastOverloadWarning >= 15000L) {
        LOGGER.warn("Woah there! Can't keep up! Running ${nextTickTime}ms (${nextTickTime / 50} ticks) behind!")
        lastOverloadWarning = lastTickTime
    }
    GlobalScope.launch { eventBus.call(TickStartEvent(tickCount)) }
    val tickTime = measureTimeMillis(::tick)
    val finishTime = System.currentTimeMillis()
    GlobalScope.launch { eventBus.call(TickEndEvent(tickCount, tickTime, finishTime)) }
    lastTickTime = finishTime
}, 0, TICK_INTERVAL, TimeUnit.MILLISECONDS)

ez

that's the actual code lol

and somehow, the main thread doesn't die

[old wyvern]

eh?

[jovial warren]

lemme show you the old code

[old wyvern]

Also, stop GlobalScope abuse

[jovial warren]

ignore that for now lol

while (isRunning) {
    val nextTickTime = System.currentTimeMillis() - lastTickTime
    if (nextTickTime > 2000L && lastTickTime - lastOverloadWarning >= 15000L) {
        LOGGER.warn("Woah there! Can't keep up! Running ${nextTickTime}ms (${nextTickTime / 50} ticks) behind!")
        lastTickTime += nextTickTime
        lastOverloadWarning = lastTickTime
    }
    GlobalScope.launch { eventBus.call(TickStartEvent(tickCount)) }
    val tickTime = measureTimeMillis(::tick)
    val finishTime = System.currentTimeMillis()
    GlobalScope.launch { eventBus.call(TickEndEvent(tickCount, tickTime, finishTime)) }
    lastTickTime = finishTime

    if (tickTime < TICK_INTERVAL) delay(TICK_INTERVAL - tickTime)
}

this is the old code

and this would chill at 16 TPS

[old wyvern]

launching coroutines might have significant overhead

[jovial warren]

lemme try not doing that

[old wyvern]

Sure

[jovial warren]

still chills at 16

[old wyvern]

Also is this happening inside a couroutine context??

Use it on its own thread

[jovial warren]

still that same runBlocking yes

[old wyvern]

Try without that

[jovial warren]

also, won't that kill the program since the main thread will stop executing?

[cinder flare]

"Woah there!"

[old wyvern]

Wdym?

Run that outside a coroutine context on the thread you want blocked

[jovial warren]

removed the runBlocking and replaced delay with Thread.sleep and guess what

[old wyvern]

Still same?

[jovial warren]

still 16 TPS xD

[old wyvern]

Thats really weird

Profile it

[jovial warren]

how?

[old wyvern]

Use any profiler

[jovial warren]

I'm using spark atm for profiling (yes, I wrote a spark impl for Krypton so I could monitor this stuff lol)

[old wyvern]

Use hte one built into ij

[jovial warren]

also, maybe it might be worth adding a profiler at some point, like what Mojang code has

[old wyvern]

^

[jovial warren]

like one that can push to listening profilers

[old wyvern]

Just use the debugger for now

[jovial warren]

like push tick starts and stuff

alright

flight recorder?

[old wyvern]

JProfiler

[jovial warren]

alright

if my trial hasn't ran out yet lol

right, where am I looking?

main seems to do a hell of a lot of waiting

[old wyvern]

If you're getting an avg of 16 handling things normally id assume you have some bottleneck somewhere

[cinder flare]

yeah I'm impressed you don't have 20 without any plugins or any players

[hot hull]

pathetic

[jovial warren]

I have LuckPerms and spark, but I've removed LP before and it did nothing

[old wyvern]

bard screen share in vc?

[jovial warren]

sure

[hot hull]

Bardy, have you tested it being ran outside of IJ yet?

I wanna throw it on my survur :sadge:

[cinder flare]

ooh yeah that'd be cool

we can get the whole gang together to start rewriting open source plugins for Krypton!

[hot hull]

FrozenJoin for Krypton 😏

[cinder flare]

ooh never heard of it

is it your plugin?

[stuck harbor]

FrustyJoyn

[hot hull]

@onyx loom Start flaming this dude for not knowing what that is

[onyx loom]

eeeeeeeee

[cinder flare]

im typing as fast as I can!!!!

oh ew wtf is songoda

[onyx loom]

frozenjoin good

[cinder flare]

oh damn we got the whole gang of contributors here

[hot hull]

would it be worth making actions, which take in any event, and execute whatever you want?

[cinder flare]

Frosty, BM, Yuri, and Piggy!

so uh, what does this bad boy do

cool particle effects or something upon join?

[analog crater]

Does anyone have any good tutorials for ktor and react.kt?

[old wyvern]

matt may be able to help

[hot hull]

Whatever you desire on join

[cinder flare]

such as?

[hot hull]

https://github.com/Frcsty/FrozenActions

[static zealot]

This is just one of the many testimonies on how bad Frosty's code is. /s

[cinder flare]

Maybe the code ain't bad, just the documentation lol

[hot hull]

what documentation?

Also yea the code is shit

[cinder flare]

Least it's Kotlin

can't be as bad as java haha

[hot hull]

Oh yea this is also in kotlin

Completely forgot

[analog crater]

Couldn't ActionHolder.kt be a data class?

[hot hull]

.

[oak coyote]

It’s not the worse I’ve seen don’t beat yourself up 😂

[hot hull]

@jovial warren I'm waiting for this greatness to happen

[cinder flare]

yoooooo it's #2!

[hot hull]

Well yes

[cinder flare]

poor airplane

[hot hull]

airplane is just there cause it loads fast

[prisma wave]

🥲

[jovial warren]

soon™️

[hot hull]

What would be the cause of this again?

pings the server just fine, just fucks it when I try to connect

[oblique heath]

it broke

restart it 🤷‍♂️

that looks like a bungee message, so it seems like the backend servers aren't reachable

[cinder flare]

stupid bungee

velocity gang

(never used either, just like having opinions :)

[oak coyote]

They both do the same thing

Just one was made with hindsight from the other

[cinder flare]

exactly! just like Java and Kotlin! And look at the difference there

Does Velocity have good error messages tho? This kinda looks a little painful

[oak coyote]

Not really

I can’t find you the server nor fallback server so goodbye

Not exactly hard to understand

[cinder flare]

hmmm maybe the io.netty part threw me off

[oak coyote]

An expception call yeah for the developer

It’s why you should read the first bit

[cinder flare]

I'm a developer and I still got scared 😋

[hot hull]

waterfall gang

[cinder flare]

oh which one is better

[hot hull]

velocity

however velocity isn't gonna be permanent

[cinder flare]

oh?

[hot hull]

It's gonna be maintained so long larger servers use it, after that I doubt anyone is gonna bother

[cinder flare]

Well isn't that... the state of every piece of software?

[hot hull]

Nah stuff like paper will always be maintained, since people can fix shit themselves

[cinder flare]

and people can't fix Velocity?

is Waterfall gonna stay around then?

[hot hull]

Can someone try connecting to frosty.op65n.tech

[cinder flare]

mc connection?

[hot hull]

yes

[cinder flare]

bet

https://i.imgur.com/Qa0qG6Q.png

👀

[hot hull]

Would appear I may have fucked a port or something

used the wrong port smh

[cinder flare]

smh

[oak coyote]

Have you got it on a proxy @hot hull

[cinder flare]

awe now im not whitelisted :'(

[hot hull]

Yeah this port was bound to the krypton server cause I'm a retard

Yes Jerry

[oak coyote]

🤡

[hot hull]

stop bully

[oak coyote]

Hehehe

[onyx loom]

always bully

[hot hull]

@ocean quartz Can we get FrozenActions support for mf cmds?

[cinder flare]

Make a PR. you won't

[hot hull]

He's rewritting it, so no I won't ;C

[cinder flare]

awe too bad

[jovial warren]

fixed weird ticking times btw

guess what it was

[onyx loom]

what was it!

[jovial warren]

Thread.sleep apparently has about a 10 ms overhead

[onyx loom]

lol

[jovial warren]

so I was sleeping for just over 60 ms instead of the 50 ms I should've been sleeping

[hot hull]

Damn you unproductive af sleeping for 60ms

[jovial warren]

ffs

no, the main thread was sleeping for just over 60 ms

[onyx loom]

/s

[jovial warren]

lol ik Kaliber

[prisma wave]

elara/threads::sleep 50
0 overhead

[onyx loom]

damn thats crazy

[prisma wave]

yes

this is because every elara function compiles to just a single line of assembly

fastest possible operation

[jovial warren]

calls JVM Thread.sleep

or have you finally decided to ditch the JVM

[old wyvern]

It wasnt an overhead

[prisma wave]

thats always been planned

[old wyvern]

Its just that the next time the scheduler ticked was 12 millis after the wake time

[hot hull]

@ocean quartz wakey wakey, if I set the nbt tag to null, will it remove it?

[jovial warren]

can anyone here tell me how to link C files properly with JNI?

I read a tutorial but it didn't seem to work

I just wanna write some JNI code in C and call it from Java lol

[lunar cypress]

what are you doing exactly?

[jovial warren]

I followed https://www.jetbrains.com/help/idea/setting-up-jni-development-in-gradle-project.html

but the Java compiler complains native_sum isn't in java.library.path

#include <jni.h>

JNIEXPORT jlong JNICALL
Java_dev_bombardy_testing_NativeMath_sum(JNIEnv *env, jint number) {
    long sum = 0;
    for (int i = 0; i < number; i++) {
        sum += i;
    }
    return sum;
}
```this is my C code btw

[lunar cypress]

Where do you load the library?

[jovial warren]

you talking about where I call System.loadLibrary?

inside of NativeMath

[lunar cypress]

yes

[jovial warren]

actually maybe the static block should go at the bottom

[lunar cypress]

that does not matter at all

[jovial warren]

public static native long sum(final int number); this is my native method

System.loadLibrary("native_sum"); then this is how I load the library

[lunar cypress]

If you have copied the build.gradle file it will only add this to the library path for the test task

which is not what you want I presume

[jovial warren]

I'm running the test task

at least, I should be

I'm just trying to do some testing with JNI

[lunar cypress]

so you are running gradle test

[jovial warren]

lemme try doing that

[lunar cypress]

what's in build/libs/hello/shared

[jovial warren]

ah, I see the issue actually

> No tool chain is available to build for platform 'windows_x86':
    - Tool chain 'visualCpp' (Visual Studio):
        - Could not locate a Visual Studio installation, using the command line tool, Windows registry or system path.
    - Tool chain 'gcc' (GNU GCC):
        - Could not find C compiler 'gcc' in system path.
    - Tool chain 'clang' (Clang):
        - Could not find C compiler 'clang' in system path.

[lunar cypress]

yes, you need to build the library before you can use it

[jovial warren]

so what have I gotta get then? VS?

or can I somehow get GCC on Windows

[lunar cypress]

you can't. you don't have to install the full VS though

in the installer you can select to only install the cpp build tools

I'd assume you need the same stuff as you need for the rust installation

You could also try to see if it works with WSL (it should)

If you don't want the effort

[jovial warren]

I'm in the individual components section of VSC, which ones do I actually need?

[lunar cypress]

you're in the visual studio installer?

[jovial warren]

also, WSL doesn't work for me atm, since WSL 2 requires the hypervisor enabled, and that breaks VirtualBox

[jovial warren]

yes

what should I be linking with? MSVC?

[lunar cypress]

you need this

[jovial warren]

I have that installed

maybe I'm missing something

which tools do I need ticked inside of that?

[old wyvern]

wait

You cant have gcc on windows?

[jovial warren]

you can use MinGW or Cygwin according to the website

but not natively

[old wyvern]

yea

MinGW should work

[lunar cypress]

ew, mingw

[obtuse gale]

just switch to Linux you pussy

[jovial warren]

yeah true, I should do that lol

[old wyvern]

He is on linux I think

Wait

[jovial warren]

currently on Windows atm

[old wyvern]

when did you switch to windows?

Werent you running arch?

[jovial warren]

some time ago

[old wyvern]

ah

[jovial warren]

yeah I still do have Arch

I just don't use it lol

[old wyvern]

I see

[jovial warren]

I've been meaning to move back, but I just can't be assed lol

[old wyvern]

yea for now mingw should be enough

[jovial warren]

#include <jni.h>

JNIEXPORT jlong JNICALL
Java_dev_bombardy_testing_NativeMath_sum(JNIEnv *env, jint number) {
    long sum = 0;
    for (int i = 0; i < number; i++) {
        sum += i;
    }
    return sum;
}
```is there anything wrong with this code btw?

since idk whether jlong and C's long are interoperable or not

right, got MinGW installed, how do I actually use it?

[quiet depot]

try type gcc in cmd

[jovial warren]

nothing

[quiet depot]

run it thru mingw directylt ehn

[old wyvern]

Make sure you have it in your PATH

[quiet depot]

installer should add it atuomatically

[old wyvern]

It didnt for me I think

[quiet depot]

depending on where he downloaded it from

[old wyvern]

I had to add it manually

[jovial warren]

yeah it's not there

also, I didn't download it, I just used an installer I have on my system

[quiet depot]

the minimal git bash one does it automatically but the full mingw64 doesn't iirc

[old wyvern]

ah

[obtuse gale]

Probably not, I think you have to use the env to translate them

[quiet depot]

or might be other way around

[old wyvern]

https://www.baeldung.com/jni

[jovial warren]

oh btw, Git bash doesn't have gcc

apparently

[old wyvern]

From the example it looks like they can return long for jlongs

[quiet depot]

install the full mingw64 then

[jovial warren]

yeah I have it

it's just not in PATH

[old wyvern]

add it

[jovial warren]

what path do I want to add? C:\Program Files\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin?

[quiet depot]

wtf is that

where'd you download this shit from

[jovial warren]

that seemed to work

no idea, old installer lol

well, it was just sitting on my system

[lunar cypress]

jlong is an alias for long

[old wyvern]

x86_64-8.1.0-win32-seh-rt_v6-rev0

[lunar cypress]

I think

[old wyvern]

tf is this

[quiet depot]

dude they don't even make installers for the full ver last time I checked

it's just zips

[onyx loom]

bardy got a virus question mark

[quiet depot]

nah

probs not

[onyx loom]

i can always give him one tho

[old wyvern]

corona virus question mark

[jovial warren]

¯_(ツ)_/¯

anyway, I'll upgrade it another time

Gradle still can't find GCC though

[old wyvern]

thats weird

[quiet depot]

yeah idk if what I said is true, I might've been thinking of something else cuz I'm looking at their site now and looks like they do have installers

[jovial warren]

- Could not find C compiler 'gcc' in system path.

[quiet depot]

http://win-builds.org/1.5.0/win-builds-1.5.0.exe

download that

probably not a virus

try install gcc thru it

[jovial warren]

also, gcc still doesn't seem to be recognised inside of IJ's CMD

it's recognised in CMD though

[quiet depot]

open a new terminal in ij

type exit in the terminal

[jovial warren]

yeah I already tried that

still not there

[old wyvern]

huh

Reopen IJ

[jovial warren]

oh btw, apparently, this is one of the only places where NetBeans & Eclipse > IntelliJ

the fact that they have support for C and apparently IntelliJ doesn't

like they have support for these multi-language projects

[old wyvern]

wdym?

[jovial warren]

See file:///C:/Users/callu/IdeaProjects/testing/build/tmp/linkNative_sumSharedLibrary/output.txt for all output for linkNative_sumSharedLibrary.

[jovial warren]

no idea, read it somewhere

[old wyvern]

Install the plugin

[jovial warren]

https://www.reddit.com/r/java/comments/706okm/users_of_intellij_do_you_know_a_good_workflow_to/

what plugin?

[old wyvern]

IJ pretty much has everything

[quiet depot]

3 years ago

[old wyvern]

The plugin for C/C++ I assume

Whichever CLion uses

[quiet depot]

c/c++ plugin might not be up to par with clion

someone I know has complained about it

[old wyvern]

I see

[quiet depot]

saying clion > ij + c ploogin

but that might just be pebcak

[jovial warren]

anyway, any idea about my error?

[old wyvern]

It seems to run fine with Android Studio mostly

[jovial warren]

there isn't an official C/C++ plugin on the marketplace

[old wyvern]

oh?

[quiet depot]

ah

you know

I've been told this 3 times now

I always forget the exact reason why "intellij c bad"

for some reason the fact that the plugin doesn't exist just doesn't want to stick in my head

[old wyvern]

damn

[pale shell]

Probably?!

[jovial warren]

lol

when your test outputs 0 some of the time and the correct answer other times

[old wyvern]

Wonderful

Impure systems be like

[forest pecan]

🥲

[jovial warren]

actually, tell a lie, correct answer my ass

idk about you, but I don't think 20 * (20 - 1) is 1409450392

[forest pecan]

wot lol

[pale shell]

😅

[jovial warren]

can someone tell me what EXCEPTION_ACCESS_VIOLATION means?

trying to write some C code to print the size of a C long and it seems to throw that

[prisma wave]

segmentation fault

send the code

[jovial warren]

#include <jni.h>
#include <stdlib.h>

JNIEXPORT void JNICALL
Java_dev_bombardy_testing_Native_printSizeOfLong(JNIEnv* env) {
    printf(sizeof(long));
}

[prisma wave]

As a C expert I am sure it will be easy

doesn't printf take a char* ?

[jovial warren]

ah that'll be it

[old wyvern]

first arg is the format

[jovial warren]

okay what the actual fuck

[old wyvern]

the size should be the second arg

[jovial warren]

that returns 0.000000

[distant sun]

                for (i in 100 downTo 20 step 20) {
                    if (player.hasPermission(Constants.Permissions.MORE_FLY_PERMISSION.plus(i))) {
                        return i.toString()
                    }
                }

                return "0"
                
                // or

Send what you used

[jovial warren]

public class Native {

    public static native void printSizeOfLong();

    static {
        System.loadLibrary("natives");
    }
}

[old wyvern]

The C function

[jovial warren]

@Test
    public void longSize() {
        Native.printSizeOfLong();
    }

printf("%f", sizeof(long));

[prisma wave]

woozy_face

[jovial warren]

lol

[old wyvern]

use %d

[prisma wave]

Use %d I think

Ez

C expert

[old wyvern]

f is for floating point numbers

[jovial warren]

lol

[old wyvern]

d is for integers

[jovial warren]

what did I say yesterday

[old wyvern]

idk

[jovial warren]

long is 4

[distant sun]

c sucks

[prisma wave]

I'm basically Linus torvalds at this point

[jovial warren]

long is 4 bytes on Windows

no wonder I get strange errors

[old wyvern]

no

4 bytes is for 32 bit

[jovial warren]

yeah

ik

but the minimum size of a long in C is 32 bits

[prisma wave]

why don't they just use Big Integer !

[old wyvern]

nah man

long long long

long long long long long

very long long long long

[jovial warren]

so I assume ```c
JNIEXPORT jlong JNICALL
Java_dev_bombardy_testing_NativeMath_sum(JNIEnv* env, jint number) {
return (long) number * (number - 1);
}

[forest pecan]

bardy you should actually use jna instead of jni

[jovial warren]

since jlong is 64 bit and jint is 32 bit

[old wyvern]

Youll need to cast each number'

[jovial warren]

wdym?

[dusky drum]

why is Vault so demanding :/

Could not find org.bukkit:bukkit:1.13.1-R0.1-SNAPSHOT.
Required by:
         project : > com.github.MilkBowl:VaultAPI:1.7

[prisma wave]

(unsigned long long) 0

[old wyvern]

Does operations on jlong work?

[jovial warren]

no clue

[distant sun]

@dusky drum transitive = false

[jovial warren]

they seem to work Yugi

[old wyvern]

Ah ok

use long long

[jovial warren]

but I get really really weird thingies

[forest pecan]

why you use jni 😦

[old wyvern]

cast it to a long long

[prisma wave]

i64 🙂 👍 👍

[old wyvern]

wtf

They getting botted hard

[forest pecan]

what is that server

send em link

[prisma wave]

wtf

[forest pecan]

send me link

lol

[prisma wave]

Couldn't be Dev Den

[forest pecan]

apparently, 20 * (20 - 1) is 113309238466483752 @old wyvern

[old wyvern]

oh wait

[jovial warren]

something's going on here

[old wyvern]

HOLY SHIT

[prisma wave]

Lmfao

[jovial warren]

what the fuck

[forest pecan]

sned me llink

pls

[old wyvern]

Wait goddamit xD

[jovial warren]

lol

[old wyvern]

I forgot the server name itself

oh yes

TheCodingDen

You are already in it I think pulse

[prisma wave]

damn

[forest pecan]

im in bois

[jovial warren]

the channels aren't there

[forest pecan]

they just stopped

lol

[old wyvern]

They fixed it

lol

[forest pecan]

i saw the mods delete them

xd

[old wyvern]

xD

[jovial warren]

lol

[prisma wave]

how does that even happen

[old wyvern]

That whole discord is going crazy

[jovial warren]

JNIEXPORT jlong JNICALL
Java_dev_bombardy_testing_NativeMath_sum(JNIEnv* env, jint number)
{
    long casted = (long) number;
    return (long long) (casted * (casted - 1));
}
```someone please tell me in what universe that would return `-480383736` with `number` as `20`

[quiet depot]

lol

imagine a coding discord

[prisma wave]

overflow

[quiet depot]

not being able to protect itself from bots

what fucking plebs lmao

[prisma wave]

🥲

[jovial warren]

wdym overflow?

[surreal quarry]

lmaoo

[quiet depot]

when nums go over the max, they'll go negative

overflow

[jovial warren]

yeah ik

but idk how that could overflow

[lunar cypress]

I have never seen that many people type in one channel before

[old wyvern]

ikr xD

[surreal quarry]

that was nuts

[old wyvern]

Those channels were flying

[forest pecan]

why 👏 are 👏 you 👏 using 👏 jni

[old wyvern]

They disabled chat in msot channels now

[surreal quarry]

the only thing i can think of it going faster is when the official python discord got raided lmao

[jovial warren]

experimenting

[forest pecan]

jna better

🌚

[quiet depot]

is the coding den the biggest code server?

[old wyvern]

Probably not

[quiet depot]

apart from discord api perhaps

idk if that's bigger or not

[forest pecan]

theres a lot of ones out there

[quiet depot]

I assume it is

[old wyvern]

They havent fixed the invite link xD

its still weird

[forest pecan]

i got in from this sketchy ass redit npost

lol

[old wyvern]

"jamieontop"

[lunar cypress]

Tcd is one of the biggest definitely

[surreal quarry]

they have around 12k

online

[jovial warren]

wait so they didn't just get radied, they must've got hacked?

[lunar cypress]

Yep

[old wyvern]

Yea one of the admins ig

[quiet depot]

both

lol

if microsoft buys discord

minecraft accounts won't be the only accounts getting migrated to microsoft accounts 😉

[onyx loom]

😩

[forest pecan]

fuckkk

[onyx loom]

please never

[errant geyser]

That will be the day I don't use Discord anymore

[quiet depot]

I mean it's not ideal but at least it'd probably greatly mitigate bots

[onyx loom]

i still havent migrated my mc account to microsoft

[errant geyser]

^

[quiet depot]

that's because you can't

migrations start in april

[onyx loom]

huh

oh

i thought they started like 6 months ago

[quiet depot]

no

the announcement was then

[onyx loom]

nvm then 😂

[quiet depot]

it's due for april unless they changed the date

i can't remember the exact day

[jovial warren]

I think Microsoft will just leave Discord alone

like if they buy it

[quiet depot]

well

not exactly

[jovial warren]

they'll just leave it to act independently, like what they did with a few of their other acquisitions

[quiet depot]

if they buy it there'll be a lot of pressure to make it profitable at first

maybe after that they'll leave it alone

but that alone will probably require some changes

[jovial warren]

Discord is profitable though

[onyx loom]

well have to pay for the stickers kek

[jovial warren]

isn't it?

[quiet depot]

discord doesn't make a profit

[jovial warren]

ah

[quiet depot]

it's 100% reliant on investors

well

99%

1% comes from nitro

[jovial warren]

oh no

[quiet depot]

fun fact youtube doesn't make a profit either

mind you youtube doesn't lose money, but it's not profitable

they break even

[onyx loom]

damn

[jovial warren]

also, surely Microsoft wouldn't want to ruin the massive community of people who use Discord

by making servers paid or something

[quiet depot]

oh they wouldn't do that

[oblique heath]

they definitely wont do that

[onyx loom]

that would defeat the whole purpose of discord

[surreal quarry]

i really hope they integrate discord to the xbox

[quiet depot]

they would do that

[jovial warren]

yeah that's my hope too

[surreal quarry]

and then leave it alone after that lol

[quiet depot]

i thought xbox already had discord integration

[onyx loom]

but then itll never get integrated into playstation 😭

[surreal quarry]

nah

[jovial warren]

[quiet depot]

what's wrong with you guys

pc masterrace

why are you talking about consoles

[oblique heath]

phone master race

[onyx loom]

na u can link ur discord account to xbox and see what game ur playing but thats it

[surreal quarry]

i play rocket league with friends who have xbox's

[oblique heath]

/s

[jovial warren]

yeah this is one of the biggest

[surreal quarry]

so i have to use the god awful xbox app

[jovial warren]

yeah

and Discord runs on Linux

[oblique heath]

discord self hosting when

[surreal quarry]

lol

[quiet depot]

it'd be really cool if microsoft integrated skype's phone number thing into discord

[jovial warren]

Microsoft won't stop Discord running on Linux either, since they have no reason to

[jovial warren]

maybe

[onyx loom]

whats that exactly?

havent used skype in years kek

[jovial warren]

as long as they don't do what they tried (and of course, failed) to do to Skype with Discord

[surreal quarry]

i sure fucking hope not

[quiet depot]

kaliber it's a phone number that's attached to your skype account

[old wyvern]

Wait

[quiet depot]

so people can call you on a normal mobile phone and it goes to discord

[surreal quarry]

could you imagine they drop discord support for mac and linux to force windows 10 sales

[onyx loom]

oh right cool

[old wyvern]

Why would they invest on a non-profittable organisation?

[quiet depot]

in the hope that it becomes profitable

that's how investing works

companies don't start profitable

[jovial warren]

no reason really for them to do that

[oblique heath]

is discord public

[old wyvern]

I mean discord is pretty big rn

[quiet depot]

no discord isn't public

[oblique heath]

aw

[quiet depot]

although that's an option

[jovial warren]

if they still thought Linux was a "virus", they wouldn't've made WSL

[old wyvern]

Is there much more growth to be done to discord rn?

[onyx loom]

absolutely

[old wyvern]

Its very widely used

[heady birch]

Why cant I cast an int to a long

[surreal quarry]

Int#toLong

[quiet depot]

there's a huge potential market yugi

[heady birch]

yeah but it is an Object

[jovial warren]

can you actually not?

[heady birch]

which could be a int or a long

[surreal quarry]

toLong#fromInt(int)

[jovial warren]

well then that's why Niall

[old wyvern]

Doesnt pretty much everyone use it at this point tho?

[quiet depot]

no

[stuck harbor]

kneeee

[jovial warren]

you can't cast Object to primitives

[quiet depot]

discord is still mainly a "gamer" platform

[oblique heath]

a lot of people don't

a LOT

[jovial warren]

you can only cast primitives between each other

[surreal quarry]

cast it to a Long not a long

[jovial warren]

because primitives are completely different things on the JVM

they aren't classes

[old wyvern]

I see

Hmm

[jovial warren]

they have their own separate bytecode instructions

[quiet depot]

discord is still in its infancy compared to how big it could get

[old wyvern]

Also piggy i got a question about class loading

[quiet depot]

lay it on me

[old wyvern]

Ill ask in a bit

One moment

[quiet depot]

o

[jovial warren]

thinking about class loading actually, someone in Paper mentioned the other day how they thought that Paper should use module class loaders instead of URL class loaders if/when it hard forks

and just scrap loading dependencies at runtime

[quiet depot]

who said that

because depending on who said it i'll either say "lol" or

idk

maybe "lol"

yeah one of those two options

[jovial warren]

lemme see if I can find it

#555462289851940864 message

[old wyvern]

So if I had a class using a custom ClassLoader which loaded some ClassA and is now holding an instance of that class, if it returns that instance to the parent class which doesnt use this classloader, nee instances created inside that ClassA will still use the custom class loader right?

[jovial warren]

apparently, module class loaders are "the way to move the platform forward"

[old wyvern]

And all of its contents can be used by other classes even tho it doesnt use the "custom" class loader?

[quiet depot]

yeah we'll see

@old wyvern your question is confusing me a little bit

mind removing any reference to "instance" because classloaders don't touch instances afaik

should clear it up a bit

oh wait

nvm

i think I just misread

[old wyvern]

Would that still not have to load the classes at runtime?

[old wyvern]

Ok one min

[jovial warren]

sorry, I mean like what LuckPerms does

[old wyvern]

Ill write it up a bit clearer

[jovial warren]

where it loads its own dependencies at runtime

[hot hull]

@ocean quartz #dev-general message

[onyx loom]

have u ever considered that he might be sleeping

[jovial warren]

you think Frosty cares about that?

lol

also, who tf sleeps until half past 3 in the afternoon (his time I think)

[onyx loom]

me

and matt is in same timezone as us btw

[quiet depot]

I think I'm confused with what "parent class" refers to

[jovial warren]

ah yeah, Portugal isn't it

[old wyvern]

as in the class that created that other class

or rather

wait

[forest pecan]

Fefo gave me something like this about loading plugins using some form of bootstrap:

public final class PulseLoaderClassLoader extends URLClassLoader {

  PulseLoaderClassLoader(PulseBootstrapLoaderPlugin plugin) {
    // No URLs by default, they will be added as you go anyway; have the PluginClassLoader as parent class loader
    super(new URL[] { }, plugin.getPluginClassLoader());
  }

  // Don't actually expose the method, but "wrap" it
  public void addJarToClasspath(URL url) {
    addURL(url);
  }
}

public final class PulseBootstrapLoaderPlugin extends JavaPlugin {

  // Maybe add a getWhateverClassLoader method? So you can do like JavaPlugin.getPlugin(PulseBootstrapLoaderPlugin.class) to get *this* class loader and add URLs to it
  private final PulseLoaderClassLoader classLoader = new PulseLoaderClassLoader(this);
  private Map<String, PulsePluginWhatever> plugins = new HashMap<>();

  public PulseBootstrapLoaderPlugin() {
    // Some constructor logic
    // Scan a folder for your custom jars
    // Read your "custom plugin.yml"
    // Load the "main" class with the class loader
    // Call their constructors, set the dataFolder, the logger, etc (essentially what Bukkit does)
    // Save them into the Map
  }

  @Override
  public void onLoad() {
    // Call their onLoads
  }

  // Repeat for onEnable and onDisable

  public ClassLoader getPluginClassLoader() {
    return getClassLoader(); // older versions of Bukkit had this method as protected final
  }
}

public abstract class PulsePluginWhatever extends JavaPlugin { // or not, it can be fully custom unrelated to a JavaPlugin

}

I haven't tried it before, but he claims that it should work for loading all plugins. It becomes the dominant plugin loader and will load all the plugins itself. This will allow the url method to be opened cause it uses the custom classloader instead of the one provided.

[quiet depot]

oh btw a little conclusion to something I said earlier. If discord is currently somehow making a profit, I highly doubt it'll be from the simps buying nitro for their favourite streamer, it'll probably be from discord selling our data (or more accurately, the investors selling/using it).

[onyx loom]

oh no not my data!

[jovial warren]

PulseLoader

[forest pecan]

yea lol

[jovial warren]

also, that's what I do in Krypton lol

[forest pecan]

lmfao

[jovial warren]

lemme show

[quiet depot]

prolly going to china anyway so no biggie

[forest pecan]

fefo sent me that exact code

in dms when i needed help

i want to try it

[onyx loom]

oh no not china!

[jovial warren]

// this is only so we can expose addURL for internal use
class PluginClassLoader(vararg urls: URL) : URLClassLoader(urls) {

    internal fun addPath(path: Path) {
        addURL(path.toUri().toURL())
    }

    companion object {

        init {
            ClassLoader.registerAsParallelCapable()
        }
    }
}

[onyx loom]

(china i love you dont kill me pls 😄 )

[forest pecan]

so you opened the url?

[forest pecan]

im coming for you daddy

[jovial warren]

wat?

[onyx loom]

🤨

[forest pecan]

imma dial the government

(im chinese btw lmfao)

[quiet depot]

wait are you actually?

[forest pecan]

Yes

[onyx loom]

o

[forest pecan]

Brandon Li

"Li"

lmfao

[jovial warren]

yeah I was gonna say

[quiet depot]

lithium

[old wyvern]

So lets say I loaded a class "MyClass" with my implementation of ClassLoader called "TestClassLoader"

I then create an instance of this class. Some other class which doesnt use "TestClassLoader" fetches this instance.

But since the "other class" here doesnt use TestClassLoader, it will try to load the class again using extension class loader if I refer to it right?

[forest pecan]

🥶

[jovial warren]

I mean, I didn't guess that, but it's very obvious now you mention it

[forest pecan]

Yea

[quiet depot]

yugi when you say an instance of this class

do you mean a Class<MyClass>

or a MyClass

[old wyvern]

MyClass

[quiet depot]

ok

[old wyvern]

So would TestClassLoader loading it affect parent class loaders of it so I can refer to it with the other classloaders?

[quiet depot]

let's picture it this way:

MyClass: TestClassLoader
OtherClass: OtherClassLoader

In OtherClass, if you didn't wish for MyClass to also be loaded by OtherClassLoader, you would not be able to reference MyClass in code

you would only be able to interact with MyClass via reflection

[old wyvern]

hmm

Welp

[quiet depot]

that's not a big deal

explain the usage

[old wyvern]

pdm remake

[jovial warren]

gl with that one

[quiet depot]

with what

[old wyvern]

Since 9+ cant append to URLClassLoader

[quiet depot]

isolation?

[jovial warren]

yes you can?

[old wyvern]

No Imena

[jovial warren]

just expose the inner addURL method lol

[old wyvern]

The systemclassloader

isnt URLClassLoader

[jovial warren]

why tf are you manually loading classes using the system class loader

[quiet depot]

why are you trying to add things to the system class loader?

[old wyvern]

I am not

Was jsut reading up on it

The changes from 9

[forest pecan]

open module

here take a look at this class:

[quiet depot]

okie

[jovial warren]

also, surely you can reflectively access addURL anyway?

[quiet depot]

if you find anything interesting, pls let me know

[old wyvern]

Sure piggy

[jovial warren]

or do modules deny that now

[old wyvern]

Its not a URLClassLoader

[forest pecan]

https://github.com/PulseBeat02/MinecraftMediaLibrary/blob/master/MinecraftMediaLibrary/src/main/java/com/github/pulsebeat02/minecraftmedialibrary/utility/DependencyUtilities.java

[quiet depot]

would love to expand my classloader info repertoire

[forest pecan]

this works for Java 8-15

[jovial warren]

well then you shouldn't be trying to add to it

[forest pecan]

it opens the module

and loads a jar file

it doesn't work for Java 16+ however

[jovial warren]

strong encapsulation of JDK internals xD

[old wyvern]

[forest pecan]

Yea lol

[quiet depot]

yugi especially anything regarding unloading classes reliably

[jovial warren]

you shouldn't be trying to manually load classes using any internal class loaders

[quiet depot]

if you find any mention of that you might've stumbled onto a gold mine

[old wyvern]

oh god 😬

Ill let you know if I end up finding anything useful

[forest pecan]

im just confused, are you having trouble support java 9-15 or java 16+?

[quiet depot]

thx

[old wyvern]

Im still figuring out a way such that they can actually use their classes as normal evne while using this

[jovial warren]

couldn't you technically use JNI to unload classes?

[old wyvern]

One way would be have a specific entrypointclass

Which would be loaded by slimjar

[forest pecan]

So you aren't using URLClassLoader

right

[old wyvern]

Mhm

[jovial warren]

so what are you using?

[old wyvern]

Because that implementation has changed

[jovial warren]

what?

[forest pecan]

Well that supports java 9 - 15 (the URLCLassLoader one)

[pure glacier]

oh ok..

sry

[forest pecan]

in this channel

at least

[jovial warren]

#development maybe?

[pure glacier]

is there a channel?

[forest pecan]

Yeah

[quiet depot]

not sure

probably

[ocean quartz]

And don't randomly ping people, read the rules about pinging support

[pure glacier]

thx! ok..

[jovial warren]

I mean, with C, you have full control over the actual memory that's being allocated

[quiet depot]

you can control memory in java code too ||unsafe||

[hot hull]

Why was I pinged

[jovial warren]

yeah but nowhere near as well

[heady birch]

C, memory leaks, rust, never

[jovial warren]

read up you lazy shitbag xD

Fucking ass

[jovial warren]

oof

[hot hull]

God do I hate ghost pings

[jovial warren]

[quiet depot]

until u disable safe mode niall

[jovial warren]

if you can get Rust to work with JNI then please, tell me lol

[old wyvern]

[hot hull]

Pulse

[ocean quartz]

I think so, haven't tested though

[forest pecan]

https://github.com/jni-rs/jni-rs

[hot hull]

jump off a cliff

[forest pecan]

i will

[quiet depot]

ay so pulse

what time is it for u

[forest pecan]

i can't access it. But you can use URLClassLoader for Java 9 - 15

[hot hull]

will test, thanks :p

[pure glacier]

frosty pls see in #development

[quiet depot]

lol

[forest pecan]

lol

[jovial warren]

lol

patience is a virtue

[old wyvern]

What "use" are you talking about here?

The instance you get is not a URLClassLoader

[hot hull]

Nah, I'm good thanks

[ocean quartz]

How? ;o

[forest pecan]

hm remind me of your general goal again

[old wyvern]

Ofc yo ucan create your own class loader that extends it

[forest pecan]

you can load jars with it

but was the goal different

[pure glacier]

-_- i need help tho frosty

[old wyvern]

Yes but that goes into the entry point idea

[quiet depot]

@pure glacier just wait patiently for an answer in #development, if someone knows the answer they will share

[old wyvern]

Because you actually need the entry class to be created by that classloader

[jovial warren]

well you can do what everyone else has to do when they need help and wait for someone to answer you in #development

[forest pecan]

Hm yeah

[old wyvern]

Which is something I was trying to avoid

Might just end up going with that tho

[forest pecan]

Yeah that's going to be tuff

[ocean quartz]

Hmm okay, I'll dig a bit more into that, don't think It'd be too hard ;p

[forest pecan]

urlclassloader is easy for supporting java 9 -15, but after that it gets harder

[quiet depot]

yugi

when in practice are you getting a system class loader?

[old wyvern]

Awesome!! 😮

[quiet depot]

sorry if you mentioned it before wasn't following super closely

it's just in bukkit, you don't really get the system class loader

so is this for standalone apps?

[old wyvern]

Either

[hot hull]

wdym how

[forest pecan]

For bukkit shouldn't you use the plugin classloader though?

[old wyvern]

Im trying to keep it agnostic to that

[forest pecan]

You could pass in a classloader as an argument

[old wyvern]

Run anywhere

[forest pecan]

or some sort of injection

[quiet depot]

for standalone apps you could get your pdm remix to take over as the application's entry point, and then run the actual program in a url class loader

[jovial warren]

or do what Lucko did and use jar-in-jar

[quiet depot]

then deps are loaded into that class loader

[forest pecan]

you can use the boostrap class thingies for that instead

where you dominate the current classloader

[jovial warren]

wat

[old wyvern]

mhm, but it gets weird when a framework controls the entrypoint

🥲

[forest pecan]

#dev-general message

[quiet depot]

in what way?

[old wyvern]

As the actual entrypoint has a different classloader than what we want it to have

Or actually

[harsh hawk]

Where's the dev build for Deluxechat?

[quiet depot]

#deluxechat pinned

[old wyvern]

wait no

hmm

[jovial warren]

or that

[quiet depot]

I love how in depth class loaders can go

so many cases to consider

[forest pecan]

🥲

[quiet depot]

does any other topic in java go this far?

[old wyvern]

🥲

[forest pecan]

well

[old wyvern]

Turing complete generics?

[quiet depot]

I mean some probably go further, like gc

[forest pecan]

perhaps jni/jna

maybe

[quiet depot]

oh yeah generics can go real far

although that's pretty much completely abstract

[old wyvern]

Executing a program with javac do be crazy

[quiet depot]

class loaders have lots of impl details

[old wyvern]

mhm

[ocean quartz]

Like, how do you want it to support your actions? As parameters?

[heady birch]

Oracle biscuit

[quiet depot]

niall

do u play with rust unsafe

[heady birch]

Once or twice

It is my fundamental belief that "unsafe" should be avoided at all costs

[quiet depot]

I believe that's not just yours

[old wyvern]

Maybe I can just change the bytecode at compile time to make all uses of new use the classloader 🥲

[quiet depot]

it's a pretty fundamental belief in life in general; not even unique to programming, that "unsafe" should be avoided at all costs

[heady birch]

Lol

[forest pecan]

is jumping off a cliff unsafe?

[heady birch]

dpends on the CONTEXT

are you wearing a parachute?

[forest pecan]

No

[old wyvern]

Would it be considered bad if I try to change the entry classe's bytecode for this?

[forest pecan]

don't parachutes add extra weight

[quiet depot]

should be fine then

[forest pecan]

🤡

Yeah thats what i thought

[quiet depot]

parachutes can choke you

all those strings

very unsafe

[forest pecan]

Exactly

[old wyvern]

piggy

[forest pecan]

More unsafe than safe

[quiet depot]

yugi worse things have been done

I'd keep looking for another solution before putting effort into that one

[old wyvern]

Alrighty

I guess googling time

[quiet depot]

look into osgi

[old wyvern]

oh yea I read about that on a stackoverlfow thread

Bundles

[forest pecan]

isn't there also stuff like the agents
