programming

[sage crag]

it would be easier if you were using zig and had some @reverseBits() instrinsic

they could easily add this

[solid bough]

They just don't want to make people have teh ability to upload stuff to Discord

[opaque sigil]

just let the compiler do the swapping at comptime

[sage crag]

:mhm:

[sage crag]

its why im on the fence about some @memSet() intrinsic

[opaque sigil]

[sage crag]

ew

comptime arg passed with [] is strange

[solid bough]

What is that?

[opaque sigil]

i don't mind it

it makes it a very clear distinction between comptime params and runtime params which is kinda nice

[opaque sigil]

that's mojo

[solid bough]

That is some unconventional Python syntax

[opaque sigil]

yeah cause it's not python

[sage crag]

anyway, from a logical standpoint, replacing a peephole optimisation with an intrinsic is an interesting idea

[solid bough]

Wait, You tell me that something else than Python exists?

[sage crag]

buh

[opaque sigil]

python is indeed not the only programming language in existence, yes

[solid bough]

Wait, the rend.exe of the Linux server is something else, it is jsut the name of the executable

It can't run on windows

So that clears that confusion

[rigid snow]

__builtin_bitreverse exists in clang

[sage crag]

makes sense

again, its hard to apply peepholes to bit reversing manually

mhm

[rigid snow]

but uhh

[sage crag]

wtf is it doing

trashcan compiler

[tender river]

252645135 = f0f0f0f

[sage crag]

why do you know that

oddleaf

[tender river]

858993459 = 33333333

maths

1431655765 = 55555555

https://aggregate.org/MAGIC/

this looks slightly different

[sage crag]

<rev>:
        vmovd  xmm0,edi
        vgf2p8affineqb xmm0,xmm0,QWORD BCST [rip+0x1001],0x0        # <rev+0x1010>
        vmovd  eax,xmm0
        bswap  eax
        ret

here's what clang generates on my machine

vgf2p8affineqb

[tender river]

vgf2p8affineqb

[sage crag]

is crazy

[warped narwhal]

you may need a -march= flag for godbolt to get better results

[opaque sigil]

Galois Field Affine Transformation

[sage crag]

clang -O3 -march=native -mtune=native -nostdlib bit_thingy

on my machine

[rigid snow]

yeah nothing changed

[sage crag]

im not benchmarking int reversal asm

<rev>:
        bswap eax
        pdep eax 0x01010101
        pext eax 0x80808080

but i would bet this is faster on basically every cpu

and its more portable, only needs bmi2 feature

hmm though actually, clang's one is probably less likely to leak timings

[tender river]

okay what is lea doing in there what

[sage crag]

you mean you dont want to calculate the address of a memory operand and store that address in a register

#include <stdint.h>

uint32_t rev(uint32_t n) {
    return __builtin_bitreverse32(n);
}

this is what im using for src code

awa

[tender river]

i guess its just using it purely arithmetically

[sage crag]

lol

no wonder hblangs runtimes were comparable to rust

clang sucks

ban clang

[tender river]

ret = bswap(arg);
ret = ((ret & 0x0F0F0F0F) << 4) | ((ret >> 4) & 0x0F0F0F0F);
ret = ((ret & 0x33333333) << 2) | ((ret >> 2) & 0x33333333);
ret = ((ret & 0x55555555) << 1) | ((ret >> 1) & 0x55555555);
return ret;

itsthis

[sage crag]

yeah that's the unoptimised one

or, the one that assumes basic x86 feature level i guess

[rigid snow]

i can’t get it to output anything different no matter what args i throw at it

but i may be stupid

[sage crag]

ryzen

[olive sable]

it seems like lowering the resolution makes performance worse until i go the 360p where its at 9k fps again

[sage crag]

something something cache lines

[olive sable]

i still finds it weird how 1080p is faster than rendering lower resolutions

something to do with windows?

[amber fractal]

Windows upscaling to fit 1080p

also known as 1080p monitor

[olive sable]

the window isnt even getting upscaled

its not fullscreened

fullscreened native would be 1440p anyways

[rigid snow]

also in fullscreen it should be the monitor or the gpu upscaling

depends on the setting, on nvidia it’s monitor by default iirc

[olive sable]

my best geuss rn would be this thread

[rigid snow]

[olive sable]

taskmanager reports gpu as 86% while nvidia overlay says 60% so eitherway it shouldnt be gpu

[amber fractal]

Adding onto this, maybe just rendering the rest of the desktop is adding some load to it. Render layers is a term that I'm thinking.

[rigid snow]

aka just output the res the game is at

[amber fractal]

Yesh

[olive sable]

is clang that hated?

[sage crag]

i dont know

[rigid snow]

i know because many monitors do not comprehend 1440x1080 and that is a popular resolution among csgo players (they think 4:3 stretched/black bars is better than 16:9)

[sage crag]

that's why there is poll

[amber fractal]

We love the all or nothing from those that know it

[olive sable]

i have discovered that fullscreen actually fucks up performance more, it went to 5k fps

it also fucks up my windows hdr like minceraft does

[rigid snow]

hdr on windows

[tender river]

without bwap

ret = arg;
ret = ((ret & 0x0000FFFF) << 16) | ((ret >> 16) & 0x0000FFFF);
ret = ((ret & 0x00FF00FF) <<  8) | ((ret >>  8) & 0x00FF00FF);
ret = ((ret & 0x0F0F0F0F) <<  4) | ((ret >>  4) & 0x0F0F0F0F);
ret = ((ret & 0x33333333) <<  2) | ((ret >>  2) & 0x33333333);
ret = ((ret & 0x55555555) <<  1) | ((ret >>  1) & 0x55555555);
return ret;

bwap

[sage crag]

bwap

[rigid snow]

p

[warped narwhal]

Are you using a proper HDR framebuffer when using fullscreen?

[olive sable]

nope

everything is set to srgb

and 8 bit per colour

[sage crag]

yup that's byte swap alright

bwabwa

[warped narwhal]

Exclusive fullscreen sets the monitors mode directly, so if you give it an srgb backbuffer then the monitor needs to restart and load into an srgb mode

[olive sable]

im not really trying to use hdr tho, it would be nice if it made my screen go back to hdr afterwards tho

i never need to restart, but after that happens i need to go to settings and click the slider to update it or something

[rigid snow]

wouldn’t good tonemapping make them the same

[olive sable]

[rigid snow]

wait i’m on a hdr screen though

i don’t have an srgb screen

[olive sable]

me neither

[rigid snow]

i mean i have one just not rn

discord windows whoever

support hdr pngs already

it’s in the spec

[olive sable]

i optemized msot of this

i think at this point most of the performance loss is the fps counter

[rigid snow]

spawn a separate thread that will serve the fps with http

[olive sable]

how am i supposed to do that???

[rigid snow]

unironically doable af

but don’t

[olive sable]

i would outsource the fps counter to something like msi afterburner but that actually runs worse

also their frametimes only show 0.1ms, not all the decimals i need

[amber fractal]

The urge to try out asm but I don't have my laptop and the hello world tutorial I'm following fails to work at first step where I add the exit point.

The urge to try and convert the NN to asm for some reason is unreal. It would be funny

[opaque sigil]

i'd highly recommend fasm, it's actually really convenient once you have some macros setup

[olive sable]

asm is just me with dyslexia

[amber fractal]

I've been in this truck for 8 hours, can you tell that my mind is melting yet?

[olive sable]

are you driving to the east coast?

like what is happening?

[amber fractal]

This was supposed to be split into 2 days

[olive sable]

[amber fractal]

but we never got a campsite for the return trip so all in one day it is

[amber fractal]

The General Sherman Tree is a giant sequoia (Sequoiadendron giganteum) tree in the Giant Forest of Sequoia National Park in Tulare County, California. By volume, it is the largest known living single-stem tree on Earth.

[violet sand]

The moment someone will make a fps counters be a micro-service on AWS, will be the day I will switch from being a SWE to a farmer.

[olive sable]

tree

[amber fractal]

I now have photos of said tree

[olive sable]

[tender river]

wdym, fps is the perfect metric to scrape via prometheus and view in a grafana instance

[olive sable]

wait if that tree is in cali how the fuck have you been in the car for 8 hours? you live in cali

[tender river]

just ship prometheus and grafana with your game in an easy to spin up docker container

if someone's pc has limited resources, no worries, they can purchase a hosted version from your saas!

[olive sable]

actually dont answer that

[amber fractal]

You have my address :xdx:

[violet sand]

I'm in so much pain rn from those words

[olive sable]

ok so i forgot how big california is

[tender river]

erm are you sure this is gonna work

[amber fractal]

google maps is showing 4h 39m
I'm subtracting 20 minutes

[violet sand]

Spawn an http server listening to some port.
When it gets a req. it checks the saved time varible, if none sends none, and does the next action. If it exists you check the difference between the current time, and saved time, derive fps from it and send that.
After that it over writes the saved time varible, to be the new current time.

Done u can now run your fps counter as an http server

[amber fractal]

We aren't in rush hour anymore so yeah...
-# also we can't go full speed due to hauling so percentage penalty

[sage crag]

nope

try it

[amber fractal]

That works, if it is one variable read then you don't even have to worry about any of the bad stuff.

[tender river]

it does not

[sage crag]

im sory clang

[tender river]

#include <stdio.h>
#include <x86intrin.h>

inline int bitsw(int x) {
    return _pext_u32(_pdep_u32(__builtin_bswap32(x), 0x01010101), 0x80808080);
}

int main() {
    printf("%d\n", bitsw(0x01234567));
    return 0;
}

just prints 0

wikipedia has a good example of what these do

[uneven pulsar]

I'm studying IT to be a Web Dev, and hopefully after a while gain enough programing literacy to make game engines and games. I'm aiming for an associates, and I'll make sure to work extra for any other certifications, but what made you guys stick to programming? And do you think it's worth going for a bachelors or nah?

Wow discord itself, the layout has changed a lot i haven't been here in years.

[olive sable]

for me i like games, now i make games

mostly into the graphics aspect

"And do you think it's worth going for a bachelors or nah?" idk

havent gotten there yet

[uneven pulsar]

Reasonable, I'm gonna stick to Vedal's advice because he inspired me to pursue this, and learn Python first.

[olive sable]

[uneven pulsar]

I liked his old resume on his website before he took it down/replaced it on Vedal.xyz (he even removed it from wayback lol) But i respect his decision, it was a good starter portfolio though.

What other servers are good to join to learn more abt programmin?

[olive sable]

i myself am in the vulkan server

but i really shouldnt be mentioning other servers since the mods will have me killed

[uneven pulsar]

oh...

dm?

[olive sable]

nah, im not in many programmer servers

this is my main one

[uneven pulsar]

hmm. then i'll keep looking, thank you tho!

[amber fractal]

I'm only here, doing whatever I want really. My ideas outscope myself

[olive sable]

it do be like that sometimes

[uneven pulsar]

What ideas? (I will steal them)

[amber fractal]

only difference is that I'm not just in any one category of programming

[uneven pulsar]

What does that entail?

[olive sable]

i occasionally go back to this video specifically for the minecraft movement crashout
https://youtu.be/piknGokM6rY?si=UxubnOm2NE-VR25a&t=118

half of this video is just him gettign asngry cuz of wtf notch was doing 20 years ago

[uneven pulsar]

Notch had an original idea and capitalized on it early, and the rest is history, keep in mind I have never once owned minecraft my entire life.

[olive sable]

he did ye

minecrafts codebase is still quite bad tho

[uneven pulsar]

I'm sure it is, but that's a mess for... whoever bought minecraft, Notch just gets to bask in the glory now, and make Minecraft 2 I guess.

[olive sable]

we all know mojang is too lazy to do anything

they barely do their updates anymore, nevermind fix obscure bugs that have been in the code for 20 years

[uneven pulsar]

They will continue to be lazy since effort doesn't make them significantly more profits. That's just business, we just plummet the stocks a bit too much and maybe they'll change their tune for a little, and then go back to making money using good P.R. Scummy and crummy, but it yummy in money tummy.

[olive sable]

[uneven pulsar]

That's Life

[amber fractal]

Was busy. What this entails is:

• NN entirely from scratch in both concept and execution
• Creating some of #programming 's resources like FAQ and Bingo
• Making discord bots as needed for what I need (this one has been awhile)
• Nixos, Nixos
• Automation when I'm bothered to

[swift forum]

Fear

[olive sable]

Ok i have decided to cheat

[amber fractal]

cheat with gpt

[olive sable]

To reach that 10k fps im going to just turn off a lot of bg procceses

Also using only 1 monitor noz

[amber fractal]

Can't wait to ship a userspace process killer in my application for max fps

[olive sable]

Ship the linux kernel of the fastes distro you can find

[amber fractal]

Chat, which distro !vanish

[tender river]

alpine duh

[olive sable]

I hate how i end a task in task manager and it jusy pops up again

No oculus we are not using vr rn, you DONT need to run

[amber fractal]

oculus should not have autostart rights

[tender river]

facebook

[olive sable]

I think the main issue is its split into 3 tasks, and if 1 dies the other 2 resurect it

Or something along those lines idk

It goes away if i kill all of them fast enough

[amber fractal]

pkill x100 (real)

[olive sable]

Also i hate hiw nvidea has 83 diffrent procceses

[amber fractal]

nvidia app was a mistake

[olive sable]

Some of them are actually important, some run the "nvidea app" some run nvidea control panel

[amber fractal]

Control panel doen't need to run either

[olive sable]

So you cant kill the willy nimly since my display flashes black

[amber fractal]

at least on my system that's how it was

[olive sable]

Nvidia app has infinite totem of undying it seems

Oh well

[keen swift]

Anyone know how to debug a segment fault?

[olive sable]

afaik you're trying to read protected memory or something along those lines

use a debugger to see what function is doing that

[tender river]

use asan/ubsan/valgrind

or a language that actually tells you what you're doing wrong

[sage crag]

veedal

yesh

[tender river]

no?~

[keen swift]

A very fun thing:
I use mono to execute C# code on Linux
Now I think it's not my code who segfault, but mono 🥴

[tender river]

pfft

erf

[olive sable]

(what is a mono?)

[keen swift]

A software that allows you to run C# .NET Framework generated executable in macOS/Linux

Since Microsoft only cared to support windows in .net framework

I got something more useful on my windows laptop now, turn out it's stackoverflow I think

Because I put this instead of base, so it just keep calling itself 🥴

[keen swift]

When I send this message, I was genuinely very surprised on how tf I get segmentation fault

[amber fractal]

They did, .net 8 is cross platform to linux now

[tender river]

.net core != .net framework

[amber fractal]

Ah, my mistake

[keen swift]

Yep

It just due to other constraints I need to use .net framework

(school

[amber fractal]

It is at least owned by winehq now so that is also really nice

[keen swift]

Agree

Now the most annoying part: cross device debugging

[velvet crest]

You have unlocked new role

[keen swift]

Oh nice

[olive sable]

im trying to do a wsl

why is it not working?

[keen swift]

What version of your windows?(The build number as well)

[keen swift]

Hmm

Try follow this if you have any luck
https://learn.microsoft.com/en-us/windows/wsl/install-manual

[olive sable]

ah hyper-v wasnt turned on in control panel

idk what that is but its important apparently

[keen swift]

Something something allow the machine to run a virtual machine more efficiently and hopefully safely

[astral raven]

Chat is RX 9060 XT 16GB good?

[olive sable]

id say so yes

depends on your point of refernce and the price

[opaque sigil]

fyi if you plan on doing graphics stuff inside wsl2 you will not have a good time

[olive sable]

in trying to package the game jam stuff for the apt thing

but it wont work

i cant just pip install and venv isnt working and nothing is working and ubuntu hates me

according to pipx its already installed but the script cant find it

also quick sidenote

[opaque sigil]

use uv

i have done it

[opaque sigil]

[opaque sigil]

I don't get it

[olive sable]

Theywant to make it so uou can install stuff with apt in linux

[sage crag]

why didnt they just make an awesome_swarm repo on github

emh

[amber fractal]

Honestly though, I have no idea why it wasn't centralized. I mean yes distribution is tough and not wanting to package everyone's stuff even if you have source code.

[sage crag]

apt is useful on only 1 family of distros

what if im using arch

[opaque sigil]

Btw Sam

[amber fractal]

Use nix (incorrect buzzer)

[opaque sigil]

https://launchpad.net/~kisak/+archive/ubuntu/kisak-mesa you need this for opengl/vulkan on wsl2

Unless you want to compile mesa yourself

It's not that bad

[sage crag]

[opaque sigil]

Nah

[amber fractal]

My laptop's existance would like to say otherwise

[opaque sigil]

a couple max with his cpu

[sage crag]

i do not acknowledge your laptop's existence

[amber fractal]

laptops are not real

[tender river]

bwaaaa

[sage crag]

debs folder

ship the blobs

[tender river]

ubuntu users

[amber fractal]

Part where you have to do all of it in github actions:

[tender river]

its only listed as a nice to have

regardless debs have to be rebuilt sometimes when the dependencies change this is a very stupid approach

[amber fractal]

I'd accept releases

[tender river]

not to mention its bad to store debs in git repos

[jagged turtle]

I can't even set up S3

[amber fractal]

Binaries in general are bad to store, bloats your repo size for no good reason

[opaque sigil]

Sometimes you just gotta suck it up

Well not here

[jagged turtle]

I'm looking at setting something up for this at some point since I don't really like it too but atp due to various reasons I can't

also how the hell am I supposed to like
accept extra packages that way

[tender river]

the git repo has the packages source, ci builds them on ubuntu-latest and autoupdates the apt repo

[jagged turtle]

I don't own all the repos but I guess I could fork them

[amber fractal]

git submodules can be a good method as well

[jagged turtle]

there is no way I didn't think of that

fuck me bro

ok well problem (at least partially, hopefully mostly) solved

[tender river]

ubuntu doesnt have debs in its sources either

[sage crag]

aside from that, most security oriented people are never going to just trust blobs from a random repo

i dont want swarmware brand malware

[jagged turtle]

that's why one of the things is that it has to be open-source but eh

give me a sec I'm just gonna

figure this out

[sage crag]

its not open source if its a blob

[jagged turtle]

compile the source/download from a ci run and compare sha256 hash

[tender river]

many package are nonreproducible

[sage crag]

anything that need api key

[tender river]

you aren't gonna have the same build output just because the source is the same

[amber fractal]

Nix mindset

[jagged turtle]

ngl I forgot about that

[sage crag]

reproducible builds are a very hard issue to solve

it's like nix's entire schtick

[jagged turtle]

my thinking was have the stuff be hosted on smth like a serverless function that does the stuff for it but yeah idk

[amber fractal]

Best bet is still github actions

at least that one is provable

[tender river]

i looked into it and apparently they store source packages which essentially includes upstream source code + debian dir with packaging stuff

so yes you will have to use submodules

[small anvil]

ah yes I sure do love the </> keyword

[sage crag]

not keyword

bwa

[small anvil]

im tired

i havent slept in 2 days

or near 2 days

im not sure

[tender river]

go sleep

now

[small anvil]

i spent like 7 hours debugging KCP and making my own messaging algorithm

[small anvil]

but i wanna keep on working 😭

[tender river]

sleep

[small anvil]

fine

[tender river]

[small anvil]

gotta work on server meshing tmer

not good..

[jagged turtle]

I just need to figure out how to have individual build steps for each repo

that become submoduled

[sage crag]

step 1 of build server

reinvent nix

step 2 of build server

use nix

[jagged turtle]

fuck it, I might just have each package hold a "apt-package.sh" file that has the build steps

ahhhhhhhhhhhhhhhhhh

[sage crag]

rce on github actions

[jagged turtle]

ikr

thank god submodules are tied to commit hash

[sage crag]

script better not download anything

lol.

[midnight sigil]

konii konii do you have RCEs as a tv

[jagged turtle]

well yeah that's the main problem

[sage crag]

yeah

[peak elk]

i want to learn on how to code because i have a project i want to do but i need to know how to code to do it

[sage crag]

check pins

[midnight sigil]

is this a bingo?

[sage crag]

i dont think so

feels bingo though

[jagged turtle]

@amber fractal

bingo check

[tender river]

no need for that since debian source package format is standardized

[amber fractal]

erm

[midnight sigil]

show us your rce

[amber fractal]

give me a minute

[tender river]

but fetching the upstream source is somewhat of a problem

[peak elk]

i don't know the bingo card

[amber fractal]

I'm looking at a suspiciously shaped deb buildef

[tender river]

since debian requires the debian packaging info to be inside the source

[jagged turtle]

can you point that link to me I've been looking for it and either I'm looking at the wrong search results or I cannot find it

[sage crag]

no

thanks

[jagged turtle]

probably as a side effect of my 300 tabs but whatever

[peak elk]

i assume there is one but i don't have it

[midnight sigil]

no controlling konii today

[tender river]

if you want to take on that responsibility go read this entire manual https://www.debian.org/doc/manuals/maint-guide/index.en.html

You guys have not been updating bingo, I'm gonna have to update it as well once I find the latest one

[jagged turtle]

wdym you guys

i ain't responsible for anything bingo bro

or smth idk

i feel like a zombie rn

[amber fractal]

All good, I went a bit strong

Some people update the board when they find some, some don't

[jagged turtle]

i didn't even know you can update the board

[amber fractal]

It's just an image

[tender river]

also that manual links to some packaging standards (like FHS) and you should read them as well

[amber fractal]

I have at least 5 copys of the board on my phone from over time

Also thank you cloud haha

[jagged turtle]

this is (maybe not) gonna be fun

[tender river]

packaging is a hard thing and maintaining a public repo is a HARD thing

you signed up for this, i want you to fully understand the responsibility you're taking

i'm not necessarily saying you shouldn't do this, but if you do it, you don't want to make mistakes that cause your entire work to become worthless after a year or two of OS updates or a random person sneaking a virus in the repo

[jagged turtle]

yes I know

[amber fractal]

Being noob is not on the bingo card, closest slot is new chatter talks about their project which surely must have happened by now

[jagged turtle]

I'm assuming new chatter is with that symbol next to their name

Also I mayhaps accidently rmed the SVG

[jagged turtle]

I have no idea what some of those words mean 💀

[amber fractal]

I refer to the squares as slots, and this is the second bingo. I just did an impression of another chat member for that square.

Also now is time to rebuild the SVG

[sage crag]

shadow impression

[jagged turtle]

ok

[sage crag]

a better word could be charade

[amber fractal]

Noted

[sage crag]

or just "impression"

shadow impression for some reason feels more like "the impression left by a shadow" than "impression of / shadow of"

[amber fractal]

I'll try to be more clear

[tender river]

shadowlilac

[sage crag]

i forgot you existed @stark needle

its because you change your name so often

ereader fails to boot and then the world explodes

[tender river]

i think? it booted

[south needle]

there is a more effective reboot command

rm -rf / --no-preserve-root

[sage crag]

thats not reboot thats shutdown forever

[tender river]

at least get the command right

[south needle]

happy?

[noble zodiac]

it's not the reading thats slow its the opening

[amber fractal]

Man I do not want to have to do this path again, I'll do it tomorrow.

Why did I rm the only copy I had

Man I wish I did not have to use this ugly borders without doing SVG, but life isn't fair

Also on my list of things I'm doing this time. This SVG is going to have JS so that one can cross out squares.

For now I'm tired so I'll pick this up later

i think? it can use nerd fonts but just refuses to show the navbar text for some reason (which is pretty important as its hard to aim on navbar icons when i dont know where they are)

i think i'll work around this by not using waybar at all and booting straight into a reader app

I don't use waybar either. I use my own

hmm i have like 2 hours if i want to be reasonable which reader app would be realistic to compile from scratch including (some) dependencies

also i dont have xwayland

[noble zodiac]

I don't have wayland

[tender river]

i wish koreader didnt vendor every single dependency

[opaque wharf]

Have you ever used a vuln of your system because you forgot the username/password?

[sage crag]

is koreader the javascript one

[tender river]

no it doesnt use js

[tender river]

mine? no

[sage crag]

chroot is always sufficient on systems without disk encryption

[tender river]

readest uses js

[sage crag]

arent they supposed to.. you know.. throw a valid error, and not segfault?

[sage crag]

[pearl oar]

Segfault is a valid error, but in most cases it doesn't help you to figure out where's actually going wrong

[olive sable]

Goodmorning

[south needle]

morning

[rare bramble]

I mean I guess by valid error I mean unexpected case that Is handled gracefully with a helpful error message

[tender river]

it might have printed an error message

but you're simply using python to run it

you're not printing that message in python

[rare bramble]

even just something like, Err: couldnt parse input commands correctly. check documentation: (link to docs)
would be better than segfault

[tender river]

also again it probably isnt a segfault

at least from what you sent

[pearl oar]

Or you had ran into a case where no proper error handling is implemented

Then the easiest way is to use a debugger

[rare bramble]

I dont know what error 11 means, just googled it and people were calling it a SIGSEGV

[tender river]

thats a signal not a return code

[sage crag]

signals are different program return value

awa

[tender river]

return code is simply a number returned by the program where 0 indicates a success and other values indicate "probably not success"

signals are something sent to a process to tell it something, like "i want you to exit right now" or "your code tried to do something it's not allowed to do do you have anything to say about that"

you're not getting an error message because python is not responsible for telling you what the program printed

error diagnostics are up to you to implement

whats awaawwawawa?

[tender river]

bwaa i don't know what i'm doing wrong but koreader just doesn't want to show anything

[opaque wharf]

We have

• Bime
• Promptboard
• AWA5.0

[midnight sigil]

that's undefined

[opaque wharf]

It is a bit shy, please understand

[midnight sigil]

we only have "awa"(0) and "wa"(1)

there's no "aw"

[south needle]

awatism?

[tender river]

i do not understand

[south needle]

like autism but with awa

[tender river]

[opaque wharf]

"aw" does not have meaning

[midnight sigil]

so the AWA5.0 is all represented in binary, where "awa" is 0, and "wa" is 1. And in "awaawwawawa" we have "aw" occurrence, which is invalid

[tender river]

actually maybe i do understand

also i misreplied

[opaque sigil]

why can there be no perfect, flexible abstraction

damn software

[south needle]

so waawawaawawaawa is 42?

[midnight sigil]

The suffix "-ism" generally denotes a state, condition, belief, doctrine, or practice. It's often used to form nouns from verbs or adjectives, particularly when referring to philosophies, movements, or theories. The suffix is of Greek origin, reaching English through Latin and French.

[tender river]

lisp: exists

[opaque wharf]

(but (you (have (to (deal (with (this)))))))

[opaque sigil]

true, lisp solves all problems

i wonder

[midnight sigil]

yes, but all numbers are wrapped in 8-bits, so that's also invalid

[opaque wharf]

Don't wonder

[opaque sigil]

if i import every nixos module for every target they don't actually do anything unless they're used right since it's lazy

[midnight sigil]

to make it valid, it should be "awaawawaawawaawawaawa"

[tender river]

not strictly true

[opaque wharf]

See? Don't wonder

[tender river]

its more like they dont do anything because they are lib.mkIf cfg.enable

[opaque sigil]

i guess that's true

[south needle]

now i can tell people that i am a fan of awaawawaawawaawawaawa

[midnight sigil]

[opaque sigil]

is there any realistic way of dealing with the ton of singular packages that show up, obviously you can group larger groups

other than just not saving them ig

[tender river]

wdym dealing

[opaque wharf]

I forgot to press the button on my rice cooker

[opaque sigil]

i currently have 2 independent lists of packages growing
should probably make a combined base list and then add to that conditionally?

[tender river]

you can just define it in two separate modules if you want to

or in N separate modules

[opaque wharf]

Poor man immutable system

[south needle]

set an alias to please=sudo and then you dont have to be root if you ask your pc nicely

[tender river]

rest assured i know how to use sudo

[tender river]

my personal structure is:

• modules - modules (with common code for all my devices, common.nix in particular having a lot of if conditions), this allows me to reuse existing code
• hardware - hardware specific info, so if i want to (hypothetically) set up a second exactly same device i could reuse 100% of the code in here
• devices - device specific info, like partitioning or networking
• hosts - "role"-specific info, if i want to i can switch my server or my laptop to a completely different device reusing 100% (ideally) of the config in here
• secrets - not in the git repo, a single .nix file that has PII

i also have a 416 lines long flake.nix that handles the boilerplate for managing all that lol

[opaque sigil]

it's slowly but surely growing (frick you pipewire why are you so annoying)

[south needle]

mine looks kinda like this:

• modules
• outputs (there i generate the server and services (vms) and users (homemanager + user devices)
• i use sops for secret management and microvms (basically like docker on servers)

[opaque sigil]

[south needle]

each host has a default.nix with basic configurations like modules it needs, static ip addresses or users that have ssh permission to the system

this would be vm: there is a wireguard ip and a deployOn so it knows on which machine to be deployed on

i wrote 8k lines of nix code xD

and we have a int8::max of files

[south needle]

what is taking you 31k lines?

[tender river]

bwabwa look at my github

[rare bramble]

pretty happy with it now, the quality and compression ratio is pretty good. currently its configured for windows since that's what i use, dont how easy it's to make linux compatible bwa

required Pillow (pip install) and avifenc (download from their website)

[south needle]

you hava pkgs in your repo

i use my nixpkgs fork

[tender river]

sure thats 1.7k lines of code who cares

also im talking about nix code i use in general because a lot of it lives outside of my dotfiles repo

[south needle]

and you have a crazy router setup

tbh i cant find the 31k lines

[rigid snow]

nixos SCHIZO

[tender river]

8k lines of frida packaging
12k dotfiles

why libaom so slow on my pc

this is sad

librav1e was so much faster

[tender river]

av1 encoding is so slow

[rough bloom]

pretty sure that libaom is just slow

[sage crag]

i also tried svt av1

was similarly slow

sadge

[rough bloom]

you use either SVT-AV1 or rav1e

uuh try adjusting encoding options
good luck

[sage crag]

nevermind its fast now

thank you mesa update

[tender river]

[midnight sigil]

python doesn't let me handle exceptions in my own way, and it has to say "During handling of the above exception, another exception occurred: "

[sage crag]

was both faster and made a smaller file

good job svt

i recently saw a water vending machine named "live water" should i be concerned

live water (water is alive)
live water (water has a live electric current)
live, water (me telling water that we are live)

[sage crag]

banned

[tender river]

[sage crag]

i didnt tell ffmpeg to compress it though

i probably should

[midnight sigil]

the second live water doesn't make sense though

shouldn't it be living water?

[south needle]

it does only work with a supported gpu right?

[south needle]

still have laying around 7.4TB of videos in mp4

[sage crag]

probably

[opaque sigil]

you can do it reasonably fast with svt-av1 and enough threads but realtime needs special hardware

[tender river]

why is the server so slow work faster

[rough bloom]

SVT-AV1 is just a normal CPU encoder AFAIK, should work with anything

[sage crag]

obs seems to manage

[midnight sigil]

[sage crag]

maybe my cpu is just fast enough bwabwabwa

[opaque sigil]

oh yeah i guess i lied, svt can do realtime

well granted you have a beefy cpu

[sage crag]

awa

[tender river]

libaom encoding

[sage crag]

i had a similar speed

[midnight sigil]

this is the only thing I hate in AWA5.0

[tender river]

rav1e is about 5x faster

and libsvtav1 is actually usable

[sage crag]

155 KiB

[opaque wharf]

Everything can be solved with enough computing power

[sage crag]

i think that is against the fundamental theory of computing actually

[opaque wharf]

The halting problem does not apply

[rare bramble]

thats pretty good

[tender river]

a bit crunchy but it works

[sage crag]

there are more uncomputable problems than computable ones

[south needle]

i need to be above realtime (i dont have multiple years to wait)

[opaque wharf]

Is it?

[tender river]

https://cdn.discordapp.com/attachments/1072697081443131476/1330630143441506305/entire2024neurosubathon.gif

[sage crag]

yup

all computable problems can be mapped to natural numbers

[opaque sigil]

looks like nvenc is "only" 2.8x as fast as svt for me hmm

[opaque wharf]

Uncomputable as in there is no known algorithm to compute it or not enough computing power?

[tender river]

i wish osu supported avif for team banners

[sage crag]

uncomputable as in, its not possible to compute due to an algorithm not existing

arbitrarily close approximations dont count

[rare bramble]

I found 2 gifs in my testing that are pretty good quality indicators
see how much quality is lost with these

[opaque sigil]

i remember having to prove that

[sage crag]

say hello to bitcrunching

[opaque wharf]

Prove that computable function can be mapped to N?

[sage crag]

its 3kb but at what cost

[opaque sigil]

something along those lines iirc

[tender river]

its ok it still accurately represents the source image

[opaque sigil]

you basically prove that there are uncountably infinite many uncomputable functions

[sage crag]

19 kb

iuh

[rare bramble]

ye, i prioritize settings that kind of keep them intact

[opaque sigil]

computable functions can be mapped to encoded turing machines so you can count them

[opaque wharf]

Let's make an evil compression algorithm

[sage crag]

i think the easiest way of thinking about it is that every program can be represented in binary

[opaque wharf]

Where it adds data for no good reason

[sage crag]

hence every program is representable as a single natural number

[opaque sigil]

                             out7.avif

here's what i used

the main reason the quality goes down is im using crf 45

at 38 it would be fine probably

[opaque wharf]

He named the monster

[midnight sigil]

maybe just because of this, I want to write my own C++ port of AWA interpreter

this is so nut

[sage crag]

i tried to add -irefresh-type 1 but it didnt work

maybe additional savings there

[opaque sigil]

i like conway he got me extra points for running his game of life on a couple nodes in parallel

ignore the fact that it was utterly unusably slow

[sage crag]

could also try swapping -tiles 4x4 for -tiles 8x1

there's a version of life that runs on the gpu right

it runs in the same way as falling sand games

[tender river]

game of life should be relatively easily parallelizable

[opaque sigil]

communication overhead go brr

[rare bramble]

also gave up on ffmpeg for .avif conversion because I couldnt get it to keep transparency with gifs for some reason

prob skill issue

but I really did try

[sage crag]

colour space conversion is notoriously hard

i suppose you are using SvtAv1EncApp?

[rare bramble]

avifenc for png to avif

[rough bloom]

I assume you have to sync at every time step?
that would explain it when the computation being performed is so simple

[sage crag]

dont tell me you are converting every frame to a png

[opaque wharf]

Wait, you were taught by him?

[sage crag]

and then stitching those to an avif

[rare bramble]

https://cdn.discordapp.com/attachments/1401130728464580718/1401133051685113856/o8ugD6m.avif

[sage crag]

god that sounds awful

[opaque sigil]

you need to sync and swap values at every iteration yeah

[rare bramble]

and I have to fetch the frame durations from the gif so that I can reconstruct the avif with the correct frame durations

[opaque sigil]

nah i just had to parallelise the jacobi algorithm and it's very similar so i added a version with conway's game of life as a bonus

[rough bloom]

surely you could do some shenanigans to avoid large copies since you only ever need access to neighboring cells
you could even start the computation before the copy is done
will still always need a barrier though ofc

[opaque wharf]

Ahh yes, speculative execution

[opaque sigil]

you can copy the previous result while calculating the next one or something yeah

[rough bloom]

wouldn't even have to be speculative, just calculate the cells that depend on the copy last

[sage crag]

my thought process is that you can run life as a gpu kernel

[opaque sigil]

problem is that even an async copy takes far longer so you end up waiting regardless

[tender river]

if

i could

[sage crag]

apply some convolution to every 3x3 region of pixels on the screen

[rare bramble]

also ffmpeg fails miserably with some gifs' frame durations, here is an example:

vs original:

[rough bloom]

yeah, you can probably do this for a few frames ahead of the last running copy but it still wouldn't be very effective

[opaque sigil]

doing more transfers helps funnily enough

since you can do them all in parallel and they're a bit shorter

[rough bloom]

as long as the grid fits in VRAM this is probably one of the better solutions

[opaque sigil]

normally you'd just do double buffering and work on the entire grid in parallel

[opaque wharf]

Cue the grid is 10Bx10B

[opaque sigil]

the transfers only happen with multiple gpus

only 694 EiB at f64, easy

[opaque wharf]

100B bit is what? 12.5GB?

[opaque sigil]

10B * 10B is not 100B

also 100B bits is 100Gb so i guess yeah 12.5GB

[opaque wharf]

My ALU is fried today, please understand

[opaque sigil]

dw, so is mine

[opaque wharf]

Btw @midnight sigil lemme know when you are finished with the awa5.0 compiler

[midnight sigil]

I'm just doing a quick assembler rn

there's no way I'm actually porting it to C++

[opaque wharf]

[opaque sigil]

imagine starting a new c++ project in 2025

[midnight sigil]

imagine using rust

[rough bloom]

at least use Zig smh

it's no Rust but anything is better than C++

[midnight sigil]

yet I still uses Java and C++

well at least Python doesn't have it's alternatives-

[opaque sigil]

i really hope carbon turns out well

they sure are taking their time with it at least

[midnight sigil]

"Awa"

[opaque wharf]

I'd prefer they do that than rushing the language tbh

[midnight sigil]

wise words

[opaque sigil]

i guess i can't blame them though, c++ is an absolute clusterfuck

yea

[midnight sigil]

should I make AWA5.0 disassembler as well

[opaque sigil]

i don't mind waiting

[midnight sigil]

I can't really read in pure AWA

[opaque sigil]

except for the mojo compiler

there's so much shit implemented in mlir i can't look at

[midnight sigil]

now I can

oh now I just have to implement more checks huh

[desert plaza]

aight, now im reading the AWA5.0 spec

[midnight sigil]

more people in the community

[desert plaza]

i have some esolang experience

i wrote a rudimentary brainfuck interpreter

you should learn rizin instead of toying around with manual labor

[desert plaza]

manual labor?

[tender river]

not a reply to the particular message think of it as a ping

and overall you might enjoy doing ctfs, though it also involves stuff like cryptography, forensics, sql/command injections, etc

[desert plaza]

hmm

[opaque sigil]

the f word

[desert plaza]

what's rizin

[midnight sigil]

rizz

[desert plaza]

what

[tender river]

[desert plaza]

[midnight sigil]

oh cool

[tender river]

as for ctfs, they're the definition of "fuck around and find out", just google everything you see and you'll usually be able to solve them provided you're doing puzzles of appropriate skill level; join any ctf and have fun

[midnight sigil]

so the rizin thing is like a little IDA alternative

[tender river]

kind of? i'd call ghidra an ida alternative

[midnight sigil]

mhm

[tender river]

rizin as ida alternative is a bit of a stretch but sure both are reverse engineering tool

there's cutter (an ui built on top of rizin) that is more like an ida alternative

[midnight sigil]

I can definitely tell

[rigid snow]

even my isp knows better

[opaque sigil]

they know
