[sage crag]

it astounded me how many people believed that you could parallelise merge sort but not quicksort

it also astounded me how many people said that quicksort had a worse space complexity than merge sort, considering quicksort can be done in-place and merge sort cant

[tender river]

but merge is the only operation that would require a separate buffer and merge is easy to do in place

(i am trustworthy and never make things up based on gut feeling)

okay maybe not

hmm

[sage crag]

to do it efficiently you typically need an auxillary array thats the same size as the input array

you can it without it if you want to sacrifice some hidden constants

i think typically rotation

but im not super versed in merge sort

[tender river]

The space overhead can be reduced to O(√n) by using binary searches and rotations

https://cdn.discordapp.com/attachments/1060090228615958528/1399864129921093784/slep.gif

no algorithms

i dont want to think about them because i'll soon have to implement so many incremental data structures

[sage crag]

its O(n) by default so sqrt is a good improvement

[tender river]

n/2 is even easier

[sage crag]

if you consider stack frames its worse though

since merge sort is a recursive algorithm

[tender river]

you dont have to do that

you can just for (int i = 1; i < n; i *= 2) (roughly)

[uneven pulsar]

do i just study java instead of python for my python passage exam cuz i am stupid at python

[sage crag]

though actually, i think tail call is applicable

[proper rapids]

god damn back rooms of the sea

[tender river]

just start from chunks of size 1 and go up instead of starting top down

merge each 2 consecutive chunks using the same merge function

[sage crag]

i dont think its possible to do quicksort without stack frames

[sage crag]

or at least the standard algorithm

and i think its the same with merge sort using its conventional algorithm

[tender river]

probably true

i guess if you can't afford that little bit of temporary storage

[tender river]

i am lazier than haskell

[sage crag]

parallel quicksort is better than normal quicksort

if you do it in multiple processes you get more stack from the OS

[left solstice]

I was asking because I was curious if it was possible to make a audio file small enough to fit into the 4KB storage of this Nokia-esque phone (G8). I trimmed and re-encoded an existing audio file to 48kb/s CBR using a simple audio trimmer app but those files were still too big. What could I use instead to make a specialized mp3 audio file that could be stored and played on something like this?

[tender river]

does the phone have an sd card slot

[sage crag]

the audio data is the big part. lower your bitrate.

[left solstice]

It does but I wanted to see if it's possible to fit it onto the phones internal memory instead and also because I don't have a sd card on hand right now

[tender river]

just use an sd card the internal storage on phones like that is not made for storing video/audio/images

[olive sable]

my screenshots have proper colour now

[left solstice]

Guess that's the only reasonable way since even if I somehow get a audio file that small, it would just sound like noise when played. I was thinking about it theoretically but that's still kindof pointless anyway

[olive sable]

only took a small amount of vibe-coding

[sage crag]

the v in vedal stands for vibe coding

i dont know bash, and i wasnt interested in learning it

disabling hdr makes my youtube need to reload the page

anyways, look at my red circle

[olive sable]

circle's in computer graphics are a social construct

nothing is round

[spring mural]

what is wrong in my godot script"func _unhandled_input(event: InputEvent) -> void:

if event is InputEventMouseButton:

Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

elif event.is_action_pressed("ui_cancel"):

Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)

if Input.get_mouse_mode() = Input.MOUSE_MODE_CAPTURED:

if event is InputEventMouseMotion:

neck.rotate_y(-event.relative.x*0.01)

camera.rotate_x(-event.relative.y*0.01)

camera.rotation.x=clamp(camera.rotation.x,deg2rad(-30),deg2rad(60))" give me idias why it 's not working

[olive sable]

the error message probably knows more than we do

and use proper code boxes please

type 3 of these ` before and after the code block

[spring mural]

it sais it's in "input.get_mouse_mode()=input.MOUSE_MODE_captured:

[olive sable]

uh

lemme just

func _unhandled_input(event: InputEvent) -> void:
  if event is InputEventMouseButton:
    Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

  elif event.is_action_pressed("ui_cancel"):
    Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)
    if Input.get_mouse_mode() = Input.MOUSE_MODE_CAPTURED:

        camera.rotate_x(-event.relative.y*0.01)
        camera.rotation.x=clamp(camera.rotation.x,deg2rad(-30),deg2rad(60))

does this look right?

please use proper formating or nobody is able to read it

[spring mural]

okay

[olive sable]

= is an assignment operator, for comparison you would use ==

if Input.get_mouse_mode() = Input.MOUSE_MODE_CAPTURED:
needs to be
if Input.get_mouse_mode() == Input.MOUSE_MODE_CAPTURED:

i think thats the issue at least

[spring mural]

I will try

it worked

[olive sable]

also, you set Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE) meaning the Input.get_mouse_mode() will no longer be MOUSE_MODE_CAPTURED, so the inner if will never run im pretty sure

[spring mural]

thanks man

[olive sable]

unless i did the indentation wrong

[spring mural]

it worked in the engine

[sage crag]

@tender river managed to the vm up to 4gb/s throughput

so on the cheating test now 80% of c throughput

on single char it's 230 MiB/s

which is a lot worse than c

[tender river]

does it use fuel now

[sage crag]

yuh i made it use fuel a while ago

[tender river]

awawa

[sage crag]

[sage crag]

can you test it ples

erf

on what

[sage crag]

aaa i forgot to clang-format

[sage crag]

$str := "a"

all you need to do is

nix-shell

[tender river]

[sage crag]

slowge

interesting performance regression

why so many stalled cycles

erf its faster on stdout but slower on fib

[tender river]

what do people usually use for benchmarks

in c

[sage crag]

[tender river]

doesnt seem like theres any standard

sounds about right for c

[opaque sigil]

probably google's benchmark library

Maybe there's better ones now idk it's been a while since I've had to do this

I end up just compiling multiple versions and using hyperfine or poop (yes I know )

[scarlet arch]

Out of interest, what's your perf record call?

Been benchmarking stuff recently and there's so much stuff to configure

Oh nevermind that's stat, didn't notice haha

Can recommend using record, followed by samply import

The Firefox profiler is perfect for comparing the results

[sage crag]

@tender river can you pull and try again

i made an experiment

[tender river]

its faster

um

maybe?

yeah i think it is

[sage crag]

wahoo

[tender river]

the fluctuations are too high to say anything conclusive

and this doesnt help

is it showing the total speed

or just the recent speed

wait i know

last time it was 8.77

now its 9.36

both were in a minute

so its faster

[sage crag]

its funny because this change made the fib slower again

bwabwabwa

only by a tiny amount but i sad

experience this beautiful code

[tender river]

[chilly drift]

Does anyone know what kind of Neural Network Evil and Neuro-Sama were based off of?

[sage crag]

it was slower

[tender river]

[sage crag]

i did in fact try all of those

[tender river]

oh it makes sense that writing 0 would be faster since its branchless

i think

[sage crag]

i was already writing zero to reg 0 but

in the last commit i stopped being lazy and put it in only some of the instructions

[tender river]

distracted

[sage crag]

awawa

[olive sable]

awawa

[sage crag]

its a shame gcc's lto sucks so much

[chilly drift]

What language are you using?

[sage crag]

c

[chilly drift]

ah
I don't work with c much
I was told its a little harder than C#

[sage crag]

the only challenge of using c over c# is manual memory control

the only difference between most languages is typesystem and memory model

[tender river]

it has many benefits over C# though

such as

not being C#

[sage crag]

true

[sage crag]

aside from that its just stdlib

[chilly drift]

You know Neuro and Evil are written on C# right?

[sage crag]

they arent.

[chilly drift]

At the very least their APIs are

[tender river]

the frontend is, the backend isnt

[sage crag]

neuro and evil are "written in" python

almost certainly

their vtuber models are c#

[chilly drift]

Really? On Vedal's Github he only writes in C# Javascript and Typescript

[sage crag]

om

neuro isnt open source

[chilly drift]

I'm aware

the Neuro APIs and SDK are on his Github tho

[sage crag]

the neuro sdk is a reference implementation

[chilly drift]

I know

[olive sable]

the live2D models are rendered in unity with C# programming, the llm models are runnign in python

[tender river]

neuro sdk is for integrating games, its not part of neuro's code

[chilly drift]

I know.

[olive sable]

we're 99.99% sure at least

[sage crag]

if you know then you know what you have said is wrong

no need to be patronising

[chilly drift]

I'm not trying to be

Apologize

I am just saying, since he seems to have an affinity for C# he might have written her in C#

I havent had the privledge of watching his Coding streams though

[sage crag]

neuro's code doesnt get worked on in coding streams

[olive sable]

he doesnt actually code in the dev streams

and even if he did he wouldnt show the ai code

[sage crag]

in a long time in the past there was some of neuro's code on stream iirc

@tender river python right?

[chilly drift]

I meant I havent seen his coding streams meaning I dont KNOW if he works in python more than C#

[sage crag]

ok, so, she's python.

ta-da

[olive sable]

its a fair question i guess, but llm's in C# are basicly unheard of

[chilly drift]

Thats not true

Its uncommon but I've seen plenty

She likely is python since its easier to code in

[olive sable]

ye sure its possible, but every single main one is python

afaik

[chilly drift]

I dont code in Python much since my college classes are required to be in C#

[lilac helm]

To be fair she's Python but at this point Python is Python + a bunch of C libraries

[tender river]

i mean what else would it be

[sage crag]

its python regardless

[lilac helm]

I know. I'm just joking

[olive sable]

always has been. you cant do much in python without libraries

[lilac helm]

You can, it will just take 100× so nobody does, obviously

[sage crag]

its not really a matter of being easier, its that there's no reason to not use python when all development in this space happens in python.

if you want to, you can use torch in c# just fine. there's just no reason to.

its not faster.

[chilly drift]

Hm

[lilac helm]

Very true. And if the program is gonna be read by others you should do it in a language other comprehend. Because of that Python has turned into the language fo LLMs.

[olive sable]

sure some stuff is possible in python without libraries, like you could skip out on numpy at do the math manually. but for stuff like graphics, audio, or numerous other things you will need at least 1 library

[sage crag]

well, the same is true of any language

[olive sable]

yep

[sage crag]

if you do graphics or audio you will need to access system apis

[chilly drift]

How long have you all been programming?

[sage crag]

more than 10 years

[olive sable]

2-3 years if scratch doesnt ocunt

[lilac helm]

LMAO

[olive sable]

if it does count like 12 years

[chilly drift]

scratch imo doesnt count

[lilac helm]

I'm glad we all went through Scratch...

[olive sable]

hey my scratch programs were top tier.
the best damn code ive seen a 6 y/o make

[chilly drift]

I was recently tested on Programming knowledge and they asked questions about scratch
I havent used it since I was like 10

[tender river]

more than 10 years

[chilly drift]

you guys are old huh

[olive sable]

im 18

[tender river]

i'm over 10 years old

👵

[chilly drift]

I figured

[sage crag]

that's insane

no way

[olive sable]

since when is 18 old?

[sage crag]

this is true

still a kid

[chilly drift]

No not you

[olive sable]

these damn kids

[chilly drift]

The people who have been coding over 10 years

I'm older than you????

[olive sable]

im joking

[chilly drift]

I've been programming for around 6 years
if you count scratch make it 9

[sage crag]

its a shame gcc doesnt seem to support this attribute

clang does

[amber fractal]

I'd say 10 years, same for scratch in particular. Block programming in general it has been 12ish years. Hard to remember considering I'm 21.

[opaque sigil]

[sage crag]

clang doesnt support -mstringop-strategy=rep_byte

[tender river]

here's some of my oldest code

i was using tail recursion functional programmer by nature

[desert plaza]

i first started programming by copy-pasting batch scripts from youtube into notepad on windows 8

[sage crag]

this is the best way to write a parser though

[chilly drift]

I started with Java making Minecraft modpacks on Notepad

[sage crag]

i started with a terrible c graphing calculator

[chilly drift]

Lol

[tender river]

technically i wrote some code before 2015 when my dad showed me turbo pascal

but i didnt find it interesting at the time

[sage crag]

turbo pascal

[tender river]

i was like 6yo

[sage crag]

om

[lilac helm]

Oh that's fantastic haha

[amber fractal]

Going into middle school I started reading about scratch. But I've already used hopscotch for awhile before.

[tender river]

wait right

i wrote some bash code before i ever wrote a line of c++

[chilly drift]

Do you all thing Neuro was built off a Recurrent Neural Network or Generative Adversarial Network

[sage crag]

neither

large language model

transformers

[olive sable]

i cant find my code from 10 years ago, but i found untitled-6 from 2017 so 8 years ago.

[amber fractal]

that'd be uhhh 2015

[sage crag]

not any of CNN, RNN, or GAN

definitely transformers

hbvm

hbvm

hbvm

[desert plaza]

hbvm

[lilac helm]

If we're counting childhood coding I actually don't know when it was the first time I coded... My dad is a programmer so my younger brother and I did a lot of stuff when we were younger

[tender river]

.c

[amber fractal]

I got an clicker game somewhere on scratch. Takes about 30 minutes before it breaks into infinity, which is honestly impressive considering my age when making it.

[sage crag]

by da way, if you want to play with writing hbvm programs in machine code, i have a freestanding vm implementation here

[olive sable]

most of my scratch stuff is deleted cuz it wasnt up to my high standarts, but i know it did indeed suck

[sage crag]

it doesnt implement any of the ableos ecalls though, so you would have to write those yourself i guess

[tender river]

copy(vec.rbegin(), vec.rend(), ostream_iterator<int>(cout, ""));
wow

[chilly drift]

i might be stupid for asking this but what does hbvm mean..?

[amber fractal]

Sometimes I played it in HS because scratch was unblocked, maybe I also did it after graduating.

[olive sable]

my monitors arent in the correct order

thats interesting

ill need tto debug my hdr toggle script bwaa

[desert plaza]

that is not a stupid question

[amber fractal]

What is the script

[olive sable]

#!/bin/bash

MONITORS=("DP-3" "DP-2" "DP-1")

HDR_ON=false
for m in "${MONITORS[@]}"; do
    FORMAT=$(hyprctl monitors | awk -v mon="$m" '$0 ~ mon {in_mon=1} in_mon && $1=="currentFormat:" {print $2; exit}')
    if [[ "$FORMAT" == *1010 ]]; then
        HDR_ON=true
        break
    fi
done

for m in "${MONITORS[@]}"; do
    hyprctl keyword monitor "$m, 2560x1440@180, auto, 1, bitdepth, $([[ "$HDR_ON" == true ]] && echo 8 || echo 10), cm, $([[ "$HDR_ON" == true ]] && echo sdr || echo hdr), sdrbrightness, 1.4, vrr, 2" >/dev/null 2>&1
done

notify-send "HDR toggled" "HDR is now $([[ "$HDR_ON" == true ]] && echo "off" || echo "on")"

iuts probably that auto being a bitch

ill need to give it actuall numbers i guess

[desert plaza]

hbvm is the vm that runs hb code

[sage crag]

@tender river

void hbvm_ecall_handler(HBVm *vm) {
  auto args = vm->regs;
  vm->regs[1] = syscall(args[1], args[2], args[3], args[4], args[5], args[6], args[7]);
}

hbvm-linux

it forwards the ecalls to syscalls

[tender river]

that sounds like a good idea for testing hbvm codegen

[olive sable]

aight fixed. if only everything was this easy

[sage crag]

probably

[sage crag]

@desert plaza this is an hbvm binary that uses the linux write syscall

erm why is pv not working

ok, pv is working but piping to devnull isnt

erm

im writing to the wrong fd

genius

blazing speed

unsurprising though

this one is c native though

so its basically equivalent

which i find interesting

95% of performance

definitely being capped by syscall here

[amber fractal]

my approach would have been:

hyprland.conf

source = monitor_a.conf
source = monitor_b.conf
source = monitor_c.conf
...

monitor_{a,b,c}_{HDR,NON_HDR}.conf

# HDR on and HDR off
monitor = ...

bash script

-# I forgor how to bash

if [[ "$HDR_ON" == true ]] then;
ln monitor_{a,b,c}.conf monitor_{a,b,c}_HDR.conf
fi

[olive sable]

i just cant be bothered to have seperate configs per monitor

its either all on or all off hdr

[amber fractal]

I was actually thinking as I was writing this that I shouldn't even be using hyprland for this

[olive sable]

wdym?

[scarlet arch]

Probably a dumb question... But why

[olive sable]

screenshots look like garbage with hdr on, bt i like how hdr looks.
hdr doesnt look too diffrent but the colours look nicer in my experience.

this is what happens when i try to take a screenshot

hdr on vs off

off is left btw

[scarlet arch]

Thats not my question tho. Just... Why does one need a script to control monitors

[amber fractal]

I personally use a program called kanshi as hyprland struggles with hotpluging monitors, you can also CLI to switch configs as long as all of the requirements for it exist.

[olive sable]

i need to be able to turn the hdr off for when i want to take a screenshot

[amber fractal]

I just exec-once the program in my config

[olive sable]

im fine with hyprland for now

[amber fractal]

It's not a new window manager

[scarlet arch]

Sorry am I having a stroke? Maybe I don't follow. I'm just using KDE with whatever is default on arch. And everything just works

[olive sable]

it doesnt work here

[scarlet arch]

Oh

[olive sable]

grim doesnt do proper hdr screenshots because of the hyprland compositor or something

so everything looks like shit

and i have mapped the pause button on my heyboard to a hdr toggle now

[scarlet arch]

I don't mean to sound mean, but why use that then

[olive sable]

hdr just looks nicer imo

[scarlet arch]

Nono, the hyprland thing

[amber fractal]

https://sr.ht/~emersion/kanshi/ @olive sable

[olive sable]

sunk cost fallacy

[scarlet arch]

Oh, respectable. Have a nice day.

[amber fractal]

While hyprland is bound to the config at all times, this can switch between all defined modes

[olive sable]

kanshi allows you to define output profiles that are automatically enabled and disabled on hotplug. ye i dont really need that on my desktop. this would be nice for my laptop tho

[sage crag]

pushed, maybe go wild or something idunoo

[tender river]

[amber fractal]

You can manually call profiles from the command line as long as it matches

so one HDR profile one non HDR one and just call them

[olive sable]

hmmm

i mean what i have now works and i dont have any dependancies

ill keep it like this for now

[amber fractal]

Understandable have a nice day

[olive sable]

fucking around with hyprland hdr has drained me to the point where i just dont want to risk breakign it again

i have succesfully moved the vertexbuffer into vram

this is all a bunch of small things that dont make a visual diffrence rn cuz ram was fast enough for 12 vertices, but it does need to happen

[sick owl]

Got a question for anyone here who might be more knowledgeable about batteries than yours truly

Is the 20-80% rule actually worth bothering to stick to?

[olive sable]

i think so.

like it doesnt make that much of a diffrence, but over thousands of charges it adds up

[sick owl]

At that point, aren't you just pretending your battery is degraded from the start to stop it degrading though?

I mean you're running at 60% capacity when a thousand cycles only brings you down to 80

In my case anyway

[olive sable]

not really, since it isnt degraded that 60% lasts a decent while

[sick owl]

Surely it only lasts as long as a degraded 60% though?

[olive sable]

and ill still charge it to 100% if i have a long day ahead of me

but for casual use i dont need the full 100

[sick owl]

That was a voice typing fail if you were wondering

[olive sable]

i dont have a side-by-side comaprison

[sick owl]

Well wouldn't 60% degraded capacity 0 to 100 more or less be 60% 20 to 80 on a full capacity battery?

[olive sable]

from my perspective, noboy is forcing you to keep adhering to the 20-80 thing all the time. if you really need the 100% then the battery will be less degraded and the 100% will last longer than if you let it degrade beforehand

[sick owl]

I guess so yeah

[olive sable]

all in all it probably doesnt make that much of a diffrence unless the phone is 6 years old

[rigid snow]

there is llm ||wrapping|| stuff in like every language

[pulsar edge]

the oldest file I can think to look for is dated last modified jan 2017, but I'm pretty sure thats the date I copied it over to my new windows laptop from my old iMac

[olive sable]

i see

[pulsar edge]

pretty sure I was writing shit back in 2015, but it was script-based 3D modeling rather than programming apps

god knows when I took that java course, but it was probably sometime around 2016

[rigid snow]

it's always either py/libtorch, tensorflow, llama-cpp or any of the countless onnx runtimes

[pulsar edge]

I bet M$ is mad af about it too because they sunk so much time into ML.NET

and they were super ahead of the curve too

[olive sable]

you know what M$ should do?

[pulsar edge]

odds are python won over something better like C++ or C# because data engineers don't want to spend time learning a proper language

[olive sable]

[pulsar edge]

I think the creator of mojo said that he started off by trying to create a better AI framework in rust but nobody would fucking use it, so he conceeded and made mojo which borrows python syntax

[olive sable]

python isnt a bad language for something that isnt cpu bound. but think about the hours of wasted compute time all toghether

[pulsar edge]

yeah

its better now with pypy JIT too

but its just crazy to me that people defended python as AI glue back then before we had pypy JIT

[olive sable]

i made an index buffer
it turns out that if you have the code to make one buffer you dont need to change much to make a couple diffrent ones

[pulsar edge]

neat

I have a bit of an issue sam that you'll probably find ironic

[olive sable]

[pulsar edge]

I want to make my rendering code use the GPU instead of the CPU but I despise doing all the verbose setup bullshit

I'm pretty sure my entire architecture is incompatible with it and I have to rewrite basically everything from scratch

[olive sable]

[rigid snow]

i think it's just that python happened to be the best combo of a good scripting lang, mature ecosystem, high-levelness and general disregard to perf because 99% of the spent compute you're wrapping native code anyway. lua was another good fit (as we can confirm by torch originally being a lua lib) but i suppose the ecosystem was meh, besides, python already was basically the most popular out of this category of langs

[olive sable]

if verbose is an issue then vulkan isnt an option ye, but i doubt you would have gone the vulkn route anyways

opengl isnt too bad imo

[pulsar edge]

im using opengl through skiasharp

and even that is super verbose and virtually undocumented

[rigid snow]

i see skia

opengl through skiasharp
what does this even mean, why do you need opengl when you have skia already

[pulsar edge]

skia itself is CPU only

[rigid snow]

that's just not true and can't be

[pulsar edge]

GPU support is kindof built on top of skia

[rigid snow]

people write games in flutter

i'm not saying they should but they do

[pulsar edge]

you need to create a GPU surface specific to whatever API you want (opengl, vulkan, metal) and then it overrides certain draw calls

[pulsar edge]

I mean, flutter is kinda like a game engine under the hood

its a lot closer to a game engine than traditional UI frameworks

[rigid snow]

it is in big part because it uses skia

[rigid snow]

instead of wrapping native ui

[pulsar edge]

sam typing up a storm

[olive sable]

opengl isnt too bad imo. id consider it pretty light actually.

you just gotta do some

SDL_Init(SDL_INIT_VIDEO)
SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_CORE);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 3);

glewInit()

SDL_GL_SetSwapInterval(swapInterval)

glEnable(GL_DEPTH_TEST);
glDepthFunc(GL_LEQUAL);
glFrontFace(GL_CCW);
glViewport(0, 0, screenWidth, screenHeight);
glClearColor(0.0f, 0.0f, 0.0f, 0.0f);

and boom you have your context.
then to get objects on screen you jsut do some

//init:
glGenBuffers(1, &vbo);
glBindBuffer(GL_ARRAY_BUFFER, vbo);
glBufferData(GL_ARRAY_BUFFER, bufferView.byteLength, buffer.data() + bufferView.byteOffset, GL_STATIC_DRAW);

glEnableVertexAttribArray(0);
glVertexAttribPointer(0, vecSize, type, GL_FALSE, vecSize*4, (void*)0);
//drawing
glDrawArray(mesh.count, mesh.indexType, (void*)0)

like it looks complicated. and i left out some details. but it really isnt

[pulsar edge]

see, I lose half of those APIs through skia

which is nice that I don't have to setup the viewport and whatnot, but its annoying because I have to create, manually bind, and maintain each individual buffer as an individual IDisposable

[olive sable]

i mean, settignup the viewport is literally 1 command here

and ussualy you can leave it out

[pulsar edge]

also my code is for rendering text and 2D textures

[olive sable]

its jsut better to make sure it gets done since i dev for multiple platforms

[olive sable]

you'l need to do TTF_Init() too then i guess and do some of that stuff

i haven tried that myself tho, i just include it already

[pulsar edge]

also I would rather not raw dog opengl because I don't want to write my own font handling and text drawing

[olive sable]

thats fair

[pulsar edge]

I'm just complaining instead of actually doing it

here lemme show you what Im working with

the rendering code takes so many shortcuts because it was originally written for CPU

[olive sable]

opengl is like

-init the window
-set versions
-init opengl
-set some settings

-make your buffers
-bind your buffers
-draw

its essentiely jsut those things you need to do

[pulsar edge]

https://github.com/lay295/TwitchDownloader/blob/master/TwitchDownloaderCore/ChatRenderer.cs its all in this file

im not happy about it either

[olive sable]

you have like 30 diffrent "draw xyz functions"

[amber fractal]

The age old question of MBR or GPT I'd have to see what the pros and cons are

[pulsar edge]

ik

but most of them boil down to DrawText

the main issue is how frame disposal is handled and how AddImageSection is handled

[rigid snow]

i still don't understand what for exactly you need raw opengl...

[pulsar edge]

we create and throw away so many buffers

[rigid snow]

when you're in skia

[pulsar edge]

omg

[olive sable]

since its 2D i was expecting just a function with a text input and positiondata that would have jsut been reussed

[pulsar edge]

skia barely abstracts over opengl init

in fact, it adds some more shit on top

[rigid snow]

is it not the exact same api regardless if you use gpu or cpu

[pulsar edge]

using the GPU adds a ton of stuff you need to do before you draw and after you draw

also you can't just create and throw away buffers the way we do atm on GPU

[olive sable]

if it were me i would have just done raw opengl, but i guess thatds unfair of me to say since im used to doing that

[pulsar edge]

I promise I've spent several hours looking into this already

[rigid snow]

at least that's just code you add

[pulsar edge]

using var bm = new SKBitmap(width, height, pixformat); creates a CPU buffer, and theres no way around that

and we use that everywhere

[olive sable]

really? ive never done that
all i do is just set a uniform buffer or 2. there is no aftercare needed

[pulsar edge]

to create a GPU buffer I need to pass the GPU context around, then using that I need to create a GPU surface with a specific opengl index, and some other stuff

keeping track of indices is kind of my main issue, as well as the fact that the rendering is as forward as you could possible make it

[olive sable]

ive never used "gpu surfaces"

[pulsar edge]

GPU surfaces are the only thing exposed in skia

[olive sable]

huh

[pulsar edge]

I don't perform any text measuring at all before allocating; I alloc a new row of pixels when I run out of room

which isn't compatible with GPU because that needs to know the size of the buffer

[olive sable]

ussualy for 2D. i would just set the position with a uniform buffer, and then bind a texture, and then draw

you can even reusee the same shaders

[pulsar edge]

its annoying, but its also the right way to do it and will also increase performance by reducing the amount of data copies

[olive sable]

what are you doing where you need to grow your buffers?

[pulsar edge]

.

[olive sable]

are your buffers not the size of the window?

[pulsar edge]

im not rendering to a window

[olive sable]

huh

[pulsar edge]

https://github.com/lay295/TwitchDownloader/blob/master/README.md#chat-render-example

[olive sable]

well, i guess if it works it works

[pulsar edge]

its horrible

[olive sable]

its jsut far from what i would do

[pulsar edge]

its slow

but it works

its far from what I would do too

I didn't write the original rendering code, I've just been fixing it up slowly over the last 3 years

but now its at the point where I need to rewrite it for GPU support

[olive sable]

3 years

[pulsar edge]

Here's what it looked like before I first touched it https://github.com/lay295/TwitchDownloader/blob/20b38b350760f267547179f084832dba94181428/TwitchDownloaderCore/ChatRenderer.cs

[olive sable]

[pulsar edge]

its a little not amazing

[olive sable]

well, goodluck

i woudnt be able to do it, the skia gpu stuff sounds like actual garbage

[pulsar edge]

its annoying

its also very poorly documented as I mentioned

[olive sable]

so you say
also I would rather not raw dog opengl because I don't want to write my own font handling and text drawing
you can just use a library for that im pretty sure

altho i havent used ones for C#

[pulsar edge]

I know SDL does something like that

but it doesn't have system font support right?

[olive sable]

https://learnopengl.com/In-Practice/Text-Rendering

[pulsar edge]

you need to bundle the fonts you want?

[olive sable]

depends on the library ye

[pulsar edge]

yeah people would be super mad if I removed system font support

and my ass is not doing it myself

my NIHS stops at implementing low level rendering functions

[pulsar edge]

good lord, I am not loading each glyph individually

[olive sable]

ye the sdl one is better impretty sure

//this opens a font style and sets a size
TTF_Font* Sans = TTF_OpenFont("Sans.ttf", 24);

// this is the color in rgb format,
// maxing out all would give you the color white,
// and it will be your text's color
SDL_Color White = {255, 255, 255};

// as TTF_RenderText_Solid could only be used on
// SDL_Surface then you have to create the surface first
SDL_Surface* surfaceMessage =
    TTF_RenderText_Solid(Sans, "put your text here", White); 

// now you can convert it into a texture
SDL_Texture* Message = SDL_CreateTextureFromSurface(renderer, surfaceMessage);

SDL_Rect Message_rect; //create a rect
Message_rect.x = 0;  //controls the rect's x coordinate 
Message_rect.y = 0; // controls the rect's y coordinte
Message_rect.w = 100; // controls the width of the rect
Message_rect.h = 100; // controls the height of the rect

// (0,0) is on the top left of the window/screen,
// think a rect as the text's box,
// that way it would be very simple to understand

// Now since it's a texture, you have to put RenderCopy
// in your game loop area, the area where the whole code executes

// you put the renderer's name first, the Message,
// the crop size (you can ignore this if you don't want
// to dabble with cropping), and the rect which is the size
// and coordinate of your texture
SDL_RenderCopy(renderer, Message, NULL, &Message_rect);

// Don't forget to free your surface and texture
SDL_FreeSurface(surfaceMessage);
SDL_DestroyTexture(Message);

it does mean you need to convert an sdl surface into a opengl texture

[pulsar edge]

where the hell is the SDL_ttf docs

oh, they only have SDL3 docs, not SDL2??

[olive sable]

idk, sdl2 is being phased out i guess

[pulsar edge]

honestly, this API looks harder to work with than skiasharp

especially considering that I need to keep harfbuzzsharp around

which means I would need to render each individiual glyph to an sdl surface

[olive sable]

they have a function for that apprently

SDL_Texture *texture = SDL_CreateTextureFromSurface(renderer, surf);

and then you can directly binf the output

void SDL_BindTexture(SDL_Texture *t)
{
  glBindTexture(GL_TEXTURE_2D, t->id);
}

[pulsar edge]

I think they expect you to use the glyph APIs the same way the opengl tutorial wanted you to use freetype fonts

[olive sable]

fair. sdl can be a but annoying at times. its jsut cuz i know how it works that it looks easier to me

[olive sable]

nah sdl can do a full block of text at the same time

[pulsar edge]

I'm 95% sure it doesn't do shaping though

no shaping = no arabic, hebrew, hindi, etc.

[fleet beacon]

So much lingo I'm never gonna understand

[pulsar edge]

I hate it here

I miss when I didn't know about text shaping

however, text shaping is also really nice because it lets me break the text at individual glyphs instead of just guessing where to break

[olive sable]

sometyhing like this should work

//this opens a font style and sets a size
TTF_Font* Sans = TTF_OpenFont("Sans.ttf", 24);

SDL_Color White = {255, 255, 255};
SDL_Surface* surfaceMessage = TTF_RenderText_Solid(Sans, "put your text here", White); 

SDL_Texture* Message = SDL_CreateTextureFromSurface(renderer, surfaceMessage);
glBindTexture(GL_TEXTURE_2D, Message->id)

SDL_DestroyTexture(Message);

havent done any testing tho so idk

[pulsar edge]

it'll work for any non-shaped text

[olive sable]

hmmm

does ttf not support shaped text?

[pulsar edge]

its a really annoying problem

you need a shaping library like harfbuzz or whatever the windows kernel provides

[olive sable]

It can draw Unicode characters just fine (so Arabic, Hebrew, Hindi codepoints will render if the font supports them), but it will not do the script-specific shaping, ligatures, or bidirectional reordering you need for those writing systems.

[pulsar edge]

and I'm pretty pretty sure SDL3_ttf doesn't use harfbuzz under the hood

yeah

no shaping is basically unreadable to them

I appreciate you looking into this for me though

[pulsar edge]

hey wait what

[hexed grove]

i forgor to commit

[opaque sigil]

sounds like you have to opt into harfbuzz

[pulsar edge]

god, you have to init harfbuzz properties for each individual font you load

[olive sable]

here's an example i generated. it probably works maybe

119 lines. not the absolute worst but not great

[pulsar edge]

that might work idk

[olive sable]

ye idk either, i dont have these libraries installed

this function is getting insanely long
commandManager.init(deviceManager.device, deviceManager.indices, frameManager.swapChainImages.size(), frameManager.swapChainFramebuffers, frameManager.swapChainExtent, frameManager.graphicsPipeline, frameManager.renderPass, vertexBuffer, indexBuffer, indices.size());

i should put this in a struct and just pass that

[opaque sigil]

ManagerManager

i see 5 params

[olive sable]

i have a couple diffrent managers, and i guess the main.cpp would count as the manager manager then

[opaque sigil]

seems fine

[olive sable]

there are 10

[opaque sigil]

pass the managers

problem solved

[olive sable]

hmmm

[midnight sigil]

I just realized the folder for Visual Studio Code is "Microsoft VS Code"

[olive sable]

i cant tell if that is a good or a bad idea

[midnight sigil]

that is the top 10 programming joke in my life

[opaque sigil]

make it an extra constructor that takes the managers and calls this function

[olive sable]

isnt that just moving the problem around?

[opaque sigil]

is it even a problem

passing it as a struct has the same result

[pulsar edge]

it seems that valorant isnt gifting bonus subs this subtember? lucky me, I don't have to implement that in my renderer

[midnight sigil]

he wants to improve readability

[pulsar edge]

you think this is because of vedal breaking the hype train record lol

[midnight sigil]

struct would not work well as it would require code reader referencing

[opaque sigil]

this is c++ with vulkan, that ship has long sailed

[midnight sigil]

maybe just don't care about readability in backend

[opaque sigil]

just be like the ML libraries for some reason and take like 30 params

[olive sable]

bruh

i have renamed the repo to just "vulkan" because i have published a branch that dosnt have terrible code

i hope this doesnt break quacks bot tho

[midnight sigil]

I have a solution

put things in macros

[olive sable]

[opaque sigil]

templates

[midnight sigil]

c++

[opaque sigil]

make it as ambiguous as possible

[midnight sigil]

[opaque sigil]

[olive sable]

this i swhat i have rn
https://github.com/samvanmaele/vulkan/tree/useful_stuff

This branch is 2 commits ahead of, 63 commits behind main.

[opaque sigil]

damn he really just nuked the whole history

[midnight sigil]

git blame will lead us back in time

[olive sable]

the triangle is so fast because it completely ignores every single rule of race conditions and good code practices

thats why i cant use any of it besides the early improvements

i mean, it still does 13K fps, just not 47K like the triangle

🔺

[amber fractal]

Microsoft is losing against the code

[midnight sigil]

[tender river]

gnome 3 stability is much better than it used to be

it doesnt randomly crash every 2 seconds anymore

[sage crag]

its gnome 3

what

why

[tender river]

what

gimp 3

[sage crag]

[olive sable]

new problem, my firefox crashes if i turn off thew screen it was on

interesting

[sage crag]

vvvvvvvvvvvvv

[sage crag]

[hoary lion]

I smell yuri

[tender river]

[pulsar edge]

hi chat, which do you prefer

[sage crag]

the first one

infinitely

its far easier to read, and its less indented

[pulsar edge]

the indentation is identical between the two

[sage crag]

not the relevant part of the code

[pulsar edge]

fair

[blissful geyser]

I coded a macro in python to automatically screenshot my pc when it detects brainrot words on the screen, so it can start shaming how much braincells i lost

[tender river]

first but remove the first if and replace the end with FromResult(IsConnected)

[pulsar edge]

I can do something like this to remedy that part

[sage crag]

why would you

its just worse

lol

[tender river]

a switch on a boolean is just an if

thats what an if is

but i suppose c# ifs arent expressions

[pulsar edge]

I didnt even notice that

[sage crag]

aside from that, simplicity is the most important factor when you are working in such a high level language

no matter what you write its going to perform the same

so just write the simplest version

[tender river]

it can be argued that pattern match is as simple as the direct version

[sage crag]

the person arguing that would be wrong

[pulsar edge]

I was just entertaining the switch expression that my IDE really wanted me to use

[sage crag]

reading program downwards is the correct way to read a program

reading to the side is mental overhead

[pulsar edge]

I preferred 1 as well, but I was curious if anyone here thought different

especially the rust devs

[tender river]

pattern matches are also read downwards

[tender river]

disagree i like using less lines of code

[pulsar edge]

[C89 devs didn't like that]

lmao

[hoary lion]

fuck arrows

[sage crag]

wrong, pattern match is read downwards and then in the => direction

arrows

[hoary lion]

not one but three

[amber fractal]

Too simple for a switch imo. ifs work just fine

[hoary lion]

[tender river]

you can read a pattern match as a chain of ifs

its the same

[amber fractal]

⬆️

[tender river]

wrong reply

[sage crag]

a pattern match is only useful when there is a pattern to match

[pulsar edge]

I think there's some truth to this, but I don't agree that you should always prefer down instead of right

[hoary lion]

personally prefer chain of ifs

[sage crag]

well, i disagree with your disagreeing

use a function

[hoary lion]

arrows just makes shit confusing

[pulsar edge]

I have a few functions

[tender river]

i blame c# for not having ifs be expressions

[hoary lion]

unless super super needed

[pulsar edge]

wdym by that

[sage crag]

an expression is something that evaluates to a value

[pulsar edge]

whats an "expression" to you

[tender river]

a ? b : c is an expression

[pulsar edge]

C# has that

[tender river]

if (a) { b } else { c } is a statement

[tender river]

mhm but its not as nice to read

[sage crag]

ternaries suck

if as expression better

[pulsar edge]

ternaries have their place

[sage crag]

their place is the garbage

[tender river]

only way you arent gonna read to the side is assembly code

expression trees are normal

[sage crag]

this is like saying its not possible to completely remove the cancer so we shouldnt even try

[tender river]

no, i dont think you need statements at all

[sage crag]

there's a reason most style guides specify a maximum line length

its because long lines are unreadable

[tender river]

line length is a separate concern

[pulsar edge]

there's a reason most style guides specify a maximum line length
thats what I was talking about btw

[pulsar edge]

I mean, I could write C# with 1 indentation max if I use goto

[sage crag]

gotos have their place

their place is not in this function

[pulsar edge]

there's a single goto in this entire project

[sage crag]

why did you use a switch?

[pulsar edge]

because I needed the goto

[sage crag]

hang on

[pulsar edge]

and I didn't want to use a label

and now that I'm looking at it again, I think this code might actually throw an exception because the content might only be valid for a single read?

I don't actually know

[pulsar edge]

[tender river]

shorter vertical space gives you better overview of what your code does as long as you're able to mentally parse it

[pulsar edge]

turns out it literally is not valid with a traditional goto

[sage crag]

goto and switch here are both awful and it makes me sad

[pulsar edge]

I don't see a better way

[tender river]

of course if you collapse to much into a single line it wont be easy to read (except for some cases where there isnt too much nesting)

[olive sable]

yuri posting on main, we dont see that here very often

[sage crag]

you could just make a boolean shouldThrottle and do a second if

its not like its gonna be slower

[small mason]

Hay there, just wondering dose anybody know of a good way to learn code, I know theory of code but never picked up on it (originally VB) i don't really care what language just not MF

[tender river]

boolean control flow

[sage crag]

still better than using a switch for its default label so you can goto it

[tender river]

shouldBreak = true;
if shouldBreak { break; }

Type thing

[pulsar edge]

I hate that

[sage crag]

readable and understandable

[tender river]

no

[sage crag]

there are no problems with the above control flow

[tender river]

labels are better than booleans because they are harder to get wrong

when you're trying to achieve the same goal, anyway

[pulsar edge]

especially for rust labeled loops

I wish that was in C#

[sage crag]

booleans are better than labels because they are more explicit with intention and easier to read

[tender river]

they arent easier to read

and they arent explicit

[pulsar edge]

in this case, I disagree with both points

[tender river]

they are an adhoc solution

[sage crag]

in this case its a very clear improvement over having a whole switch

[tender river]

not really?

its just an if

semantically

ifs are easier than mangling control flow to conformance with booleans

[pulsar edge]

I don't think its worth adding the mental complexity of a boolean just to reduce the indentation by 1 and change the keyword

[tender river]

^

[pulsar edge]

I used to have more gotos in this project but I've since replaced them with saner alternatives

but this is a case where I think goto reduces complexity significantly

[tender river]

the best solution isnt one that uses the simplest concepts but one thats the hardest to get wrong as long as you perfectly know the concepts involved

and if that isn't the case, use go

[pulsar edge]

I assume this is what konii was saying was her preferred alternative?

[tender river]

yuh something like this

[pulsar edge]

in the context of the screenshot its not that much harder to read

but when you add the extra code around it, the context melds into the other surrounding statements

[tender river]

i dislike this version since it's easier to scan code for gotos and labels than for boolean reads/writes

it just obscures the control flow

[pulsar edge]

even with double-spacing between each statement, its still harder to parse imo

but I think I've also lost konii on the fact that I have some lines longer than 80 cols

[tender river]

my router code

[pulsar edge]

yeah thats fine to me

[tender river]

exactly, long lines can be fine or not fine, it depends on the context

reading long lines is something you can better at, anyway

[olive sable]

aight imma try to make uniform buffers. this should make it possible to do animated shaders

[amber fractal]

The only case I'll disagree with is when it wraps on an ultrawide monitor

[pulsar edge]

disable soft wrap and you won't have that issue anymore

[pulsar edge]

like this is horrible

[tender river]

yup

[pulsar edge]

but I'm not touching it because I'm in the process of rewriting this file on another branch

[olive sable]

i have ones 300 long

[amber fractal]

[pulsar edge]

this sucks too and its also punched down in the rewrite branch

[pulsar edge]

you dont want to know how long this line is

4pt font

[olive sable]

what in the fuck are you doing that needs sucha long line of code?

[amber fractal]

Emojis

[pulsar edge]

regex

[tender river]

[pulsar edge]

emojis were invented by the devil

[olive sable]

checks out

[pulsar edge]

also I wish C# had an stdlib function for detecting emojis that didnt need a regex

I dont wannt do the research to figure it out myself

[tender river]

does c# not have a unicode char class database somewhere

[pulsar edge]

it does for some categories, but emojis is not one of them

also I wish C# had a no-alloc unicode enumerator

we have TextElementEnumerator but it allocates a new string on the heap every time it advances with no option to reuse a buffer

[glad path]

i love pulling 12 commits after coding on a different laptop

so satisfying

[fast pagoda]

i was satisfied in a similar way pulling a large repo i had but havent touched in liek 2 months
it's so broken from dependencies that i didn't include because previously me went surely i'll just be working on this continuously forever, no need for a container or anything, and surely ill be on windows forever (i am no longer on windows)

i am no longer satisfied

exiv2 patch broke KDE's wallpaper picker nice

glad i ran pacman -Syu out of habit and now cannot open wallpapers

ayy running sudo downgrade exiv2 and then picking version 0.28.5 1 then rebooting did fix it

so if any of y'all are using KDE and suddenly can't open the wallpaper picker and updating today, do that and it'll fix it

[uneven pulsar]

is temple os worth it?

like worth my time

Torvalds in 2k25

[cobalt sigil]

never heard of this windows version

[proper rapids]

Strong words, but that's not new

At times it's rather refreshing to read something so candid

[maiden geyser]

hope i didn't kill it yet

[midnight sigil]

[maiden geyser]

alright i killed it

[proper rapids]

?

hi! im trying to learn C so i wanna ask questions
is this how typedef struct works?

Also i mistook %d for double/float so pls ignore that

[sage crag]

you dont need the first Point

[tender river]

its needed because it uses struct Point* in its own body

but also please use virtual functions for something like that

[lament igloo]

that typedef struct example is generated by GPT so that i get the general idea of it

[sage crag]

you just need to define struct Point; above and then you dont need struct Point* at all, just Point*

[lament igloo]

but is typedef struct like

typedef struct Name {
// <assign data types and vars here>
}```

?

[tender river]

not true

[lament igloo]

or do i not need typedef

[tender river]

better example

[tender river]

you do need typedef, but only if you want to use A instead of struct A

before you have defined the typedef, you will have to use struct A regardless

[lament igloo]

well... i do want multiple variables in a

X.Y kinda way

[tender river]

this is valid C

[lament igloo]

its global right?

[tender river]

(you dont even need the last line)

[sage crag]

it worked for me

[lament igloo]

also i thought of something silly

[tender river]

c23

probably

[sage crag]

either that or im forgetting a detail

[sage crag]

nop, typedef <type> name

[lament igloo]

what does typedef do again?

[tender river]

it creates a type definition

type alias

[sage crag]

defines a type

[lament igloo]

soo typedef double is valid?
if so, what for other than struct?

[sage crag]

struct name {}
is a type
struct {}
is also a type

[sage crag]

typedef uint8_t u8

[tender river]

typedef struct <name1> { ... } <name2>

name 1 - the name when used like struct <name1> *ptr = NULL;
name 2 - the name when used like <name2> *ptr = NULL;

name 1 can be omitted

[lament igloo]

isnt this just variable assignment?

like var name or smth

[uneven pulsar]

i honestly dont know but this looks like java

[tender river]

c23 errors on that too

[sage crag]

no

[sage crag]

no

[tender river]

what languages do you know

[uneven pulsar]

i know its C

but kinda similar a bit

[lament igloo]

sorry, didnt include #include <stdio.h> on the screenshot 🥀

[uneven pulsar]

okay maybe not much

[uneven pulsar]

oh

[sage crag]

it has curly brackets

[uneven pulsar]

its C

[uneven pulsar]

oh yes

[sage crag]

similarity end there

[tender river]

javascript is java so C must be java

[uneven pulsar]

its fine dw

[lament igloo]

javascript, some python, c#, java, windows batch script file

[tender river]

typedef is like using in C#

[uneven pulsar]

ew python

[tender river]

wait does C# have that kind of using

[uneven pulsar]

i dont want to be forced to learn python anymore

buuut i have a py passage exam on semptember 15

[tender river]

it does

[lament igloo]

isnt that for libraries only??

huh

[tender river]

typedef PC.MyCompany.Project Project; in C syntax

[sage crag]

by the way <type> (*name)(<args>) is a function pointer type

its not advised to put this inside of your structs

if you are using c++ use virtual functions or something

[tender river]

if you're using C++ don't use typedefs at all

[lament igloo]

aight lemme go thru w3schools for a bit

[tender river]

use using and plain struct definitions without typedef

using i64 = int64_t;

struct A { int a; int b; };

C++

[olive sable]

I have done a stupid.
The needed materials for my college course said a drawing tablet, but they meant one without the android to use on a pc
I bought the pen for my tablet with android without the pc

[sage crag]

if you are just using c, make it a plain function outside the struct:

typedef struct Point {
  double x;
  double y;
} Point;

void point_display(Point *point) {}
double point_distance_from_origin(Point *point) {}

[lament igloo]

im good with c++
im aiming for lightweight and more control i think

[lament igloo]

alr

[sage crag]

the reason you have to name it as point_display and not just display is that there are no modules in c

if you #include "point.h" its going to add display as a function, not point.display or something, if you name the function display

[sage crag]

i dont recommend using c unless you have a particular reason to

c++ is probably a better choice if you want to stick closer to typical object oriented programming

[lament igloo]

but C is quite faster no?

[umbral thorn]

no

[sage crag]

no

[umbral thorn]

[sage crag]

smart ellie

u smart

[lament igloo]

welp

[nocturne olive]

From what I know C and C++ and Rust are all equal in speed

[tender river]

no, speed depends on the code you write not on the language (as long as you're using a systems' language)

[sage crag]

in 90% of cases the language you use doesnt matter

[lament igloo]

anyways my other usage? it does a screenshot and i can overlay the screenshot and do whatever the fuck i want from there

[sage crag]

as long as it compiles to machine code it will be approximately the same speed

[uneven pulsar]

you know c++ is fast but absolute shit syntax

[nocturne olive]

At least in languages that are compiled to native, sure

[lament igloo]

its a visual thing so i can learn C / C++ more

[sage crag]

if its for learning probably use c

just because its further from c#

om

[olive sable]

Konii you're an osu player, what drawing tablets (for pc) are good for drawing?

[lament igloo]

idk ab c# atp

[sage crag]

umm

[tender river]

osu! tablets are usually not as good for drawing

[lament igloo]

c# made me rely on a dll 🥀

[sage crag]

wacom ctl 472 is cheap

[tender river]

you'll have to do your own research

[sage crag]

i use it for drawing too

[fierce nova]

use language the best for your job market

[sage crag]

xp pen deco 01 is also good for drawing and quite a bit larger

cheaper as well

[lament igloo]

my college is making me learn Java, C#, and MySQL

[sage crag]

i can only really recommend those two since ive only used those ones

[lament igloo]

[sage crag]

job market

correct

[tender river]

i have an xp-pen g640 and i can confirm it's a tablet

[sage crag]

i can also confirm it's a tablet

i do not have it though

[fierce nova]

I mean, java/c# maybe not cool kids things, but being corpo coder is a comfy life, maybe boring(Java coder here)

[lament igloo]

i heard its competitive in the CS space

[sage crag]

java enterprise devs are the most common devs

[uneven pulsar]

my technical school making me learn react php java python react and MySQL

[sage crag]

its competitive everywhere but in CS its worse

[lament igloo]

REACT LMAOOOOOOO 😭

[sage crag]

react is common

[uneven pulsar]

and its not college

[lament igloo]

im going for Bachelor in Information Technology
idk if that changes anything

[uneven pulsar]

AND PHP

[sage crag]

php still has uses

[uneven pulsar]

FUCKING PHP

[lament igloo]

XD

[tender river]

theres a lot of php jobs

[sage crag]

too many

[uneven pulsar]

can i be honest with you?

[lament igloo]

ye

[sage crag]

most code is legacy code

[uneven pulsar]

if i tell you about technical schools you would cry

[sage crag]

[lament igloo]

go ahead

[tender river]

react is good

[sage crag]

web technologies

[uneven pulsar]

so you see i didnt go to high school

[lament igloo]

yeah but i heard its laggy when not used correctly

[sage crag]

mhm

[sage crag]

so is any language

that's like saying you die when you are killed

[tender river]

and thats why you learn using it

[sage crag]

[tender river]

[uneven pulsar]

i went to a school that replaced history physics chemistry with programming

so bassicly

they taught me the same thing you learned at early age
