what's the best value second hand amd gpu rn

thursday vulkan

06:10

@Jupstar ✪ i heard shader/graphics modders complian about vulkan games harder to mod due to pipeline stuff (they are used to mod dx11) is that true?

Ewan

what's the best value second hand amd gpu rn

6600 xt or 6700 maybe

thoughts https://www.ebay.com/itm/394881563056

06:15

$125 usd

06:15

+ free ship

06:17

considering buying a xeon e-2288g for the old motherboard. basically a 9900k but the xeon version

06:17

so needs ecc and doesn't have igpu. fine by me

06:17

found some for ~$180 on ebay as well

this reminds me since i finally go live alone i wanna setup my own home server

06:33

ill use gentoo or nixos probs and use distcc to help compile the server pkgs with my main pc

who's ready for minegrub?

ill use gentoo or nixos probs and use distcc to help compile the server pkgs with my main pc

nice

06:51

what i'd do is probably dualboot macOS & clear linux or some shit with opencore

06:51

because i'm sick of needing macOS for singleton tasks and getting my 2009 imac out of the closet

06:51

and waiting for its horrible hard drive

06:51

and whatnot

i have a work m1 so its not a problem for me

nice

07:20

trying to make a static build of qt 6.5 on msys

07:20

this is no man's land

07:20

wish me luck

gl

07:30

shouldnt u go sleep

yeah

07:30

my sheets are in the dryer and it's been going for hours

07:30

i told my mom i think the vent is plugged but she says it's just too wet and i shouldw ait

07:31

as long as there's no fire i guess it's fine for now

justatest

it's been like 4 hours now

07:31

and it's just floppping around

07:31

hot wet sheets and blanket

isnt it hot there

where

07:32

usa?

u live

really depends

07:33

it's hot during daytime because it's summer for the western hemisphere, but it's getting cold now

07:33

especially at night

07:33

entering fall

its funny cuz western is relative

07:33

asia could be western

07:33

from their poc

07:33

pov

yea it's a rly stupid naming system

07:33

but this is the western hemisphere

and who decided Australia is upside down

07:34

and not us

yeah idk

Ryozuki

@Jupstar ✪ i heard shader/graphics modders complian about vulkan games harder to mod due to pipeline stuff (they are used to mod dx11) is that true?

If they don't use dynamic rendering, yes

07:35

With renderpasses u are very aware of your dependencies

what triggers me is that they call vulkan bad cuz it makes their life harder

This is good for more performance xd

i'm hoping to use my fluent design Qt code + static linking and LTOs to make an app installer for Windows that looks native but is a fraction of the size of the XAML islands counterpart & doesn't require signing etc

Ryozuki

what triggers me is that they call vulkan bad cuz it makes their life harder

Yeah, nobos xd

ffxiv

07:35

uses dx11

07:36

but they wanna upgrade graphics

07:36

idk if dx12 or vulkan

07:36

but apparently dx12 is low level like vulkan

Vulkan introduced dynamic rendering specifically for when u just want to create game more easily.. more similar to opengl

and they crybabies

Yes dx12 is similar

qt docs about static builds are really shitty in general so i don't know if i can use the current cmake integration to use my own libs or not

07:39

for now i'm just raw dogging it per se but im running into issues with macros n stuff

@Jupstar ✪ prepare tomorrow rust question

07:40

@ReiTW asked me interesting things in dm, maybe next time put it in this chabnel

yup

About rust?

07:49

First part of a story on how I’ve built 25 Gbps router for home use.

oh

08:10

maybe i can make the server act as a router too

just when i thought i had it

08:13

i forgot to pause my music

08:16

75 bytes

08:16

nice readme guys

08:16

damn it doesn't embed

08:16

If this directory is empty, you probably forgot to compile the Qt library.

https://without.boats/blog/generic-trait-methods-and-new-auto-traits/

i got it to compile with my bullshit cmake

08:58

35MB exe with dumb linker and without LTOs

08:58

not too shabby

lto should reduce size tm

yep

why r u on windows

but it is hard to set up with Qt

Ryozuki

why r u on windows

it works for me

so u left gentoo

08:59

u cant be in the club

oh well

BASEDHALT

yea like a week ago exactly i thought man this install is driving me nuts

09:00

so i made a windows install medium and installed right over the gentoo. no backup

09:00

and ever since i've been living large

09:00

things have been working

2 bad

09:00

i guess u need more linux xp

so what if i do

09:00

stuff is working

dont be angry i didnt mean it bad

o

why not try linux mint

i've used mint

09:01

and i used arch for 2 years

i never used it

it wasn't the gentooisms that were driving me nuts

09:01

it was the linuxisms

arch is considerably more easy than gentoo

yeah

09:01

it is

and now probs even easier

09:02

they made like a auto installer

09:02

with python smh

oh cool

09:02

is it official

https://wiki.archlinux.org/title/archinstall

seems neat

lol

im close but i'm having bad errors

10:08

the Windows platform plugin is having these undefined references BrotliDecoderDecompress (by proxy of freetype) WindowsCreateStringReference RoGetActivationFactory

10:08

the first one i have no idea how to deal with since, as freetype is being linked against statically, it should then be linking brotli statically; but i have no static brotli on my system even with the pkg installed

10:09

the latter two seem to be msvcrt functions which i obviously can't link against statically

too bad ur among linux enthusiasts

More like extremists

10:48

Gentoo can do

who's ready for minegrub?

Already have it installed

@Jupstar ✪ does wayland still force vsync

13:04

is it working nice with sdl2?

The new mesa will finally allow no vsync

Ryozuki

is it working nice with sdl2?

From what i see it works quite ok. As long u have a stable mesa. Which was a bigger problem for me yet

hey i am looking for the offsets of the game because i want to do a deeplearning bot for myself. Can you help me to have it ? thanks

no botting

not for cheat + it will be only in local not on public servers

yed loo

15:28

lol

15:28

i sent u my xinitrc and bash profile

who

Oh

15:29

:p

Nathan_

as i said its for a project for school

RL or ML ?

ML

sry I meant RL or UnSL or SL?

I only need the offsets of the game ( i didnt said but its for a friend cuz of its school project) idk what RL or UnSL or SL mean

15:34

he told me for the offsets

Reinforcement learning, Unsupervised learning, Supervised learning

15:34

btw what do you mean offsets?

reinforcement learning

15:35

sec i will tell him to come here cuz im dumb

15:36

@DUPE

15:36

he need to wait 10min for talk

15:37

@Mr.Gh0s7 can u dm him

15:37

its dupe

ok

ty

what offsets

15:40

memory offsets?

15:40

bro

15:40

just compile the game

15:41

u have the source code

15:41

"hey give me offsets i wanna make a client side bot" in the dev channel that wants to fight against bots

15:41

i wonder if common sense exists

yeah I don't know either xD

Ryozuki

bro

yes

Ryozuki

memory offsets?

yes thats it

well the answer is

15:44

find them urself

..

have fun

my friend asked for them cuz its hard to find

15:44

so

15:45

if anyone found them

15:45

maybe @fokkonaut or chillerdragon:

im telling you

we're chads here we compile it from source code kek

kek

(edited)

THE GAME IS OPEN SOURCE

ik

15:46

my friend dont know how to find the offsets

15:46

thats why he is asking for it

Ryozuki

THE GAME IS OPEN SOURCE

What if he/they are completely new to ddnet codebase, giving them a hint wont kill u right?

1

actually

15:47

they are asking stuff that is on a level where understanding ddnet code should be trivial

15:48

the fact they are asking means they probs dont know what they doing

we are asking to learn

well this is not a reverse engineering discord

tell us how to find then we will do it by ourself (edited)

no

15:48

go find a tutorial

15:48

on how to find memory offsets

15:48

generally

15:49

then u apply that knowledge here

..

If I ask it's because I don't know how to do it, I understood that it was open source but that's not my question

ill give u a hint

15:49

ur probs on windows

15:49

use cheat engine

15:49

find a tutorial

15:49

on how to find offsets with that program

I know you have to use it but if I ask I don't know how to do it

Ryozuki

on how to find offsets with that program

we will see for thats thank you

u find resources in the internet

I am a dev not a reverse engineer

same

15:50

but u want to do RE stuff

15:50

what u are or not doesnt matter

15:50

u go and learn

15:51

to my knowledge there are no RE experts here

teach us ig

kek

1

im not an expert

thats not a problem if you know how to find them

me neither, that’s why I’m asking you for help

i dont know much either

15:51

but i already gave u pointers

15:52

cheat engine and find tutorials

maybe fokkonaut or chillerdragon will know ?

i highly doubt

Doubt

what does doubt mean

that i think they dont know either

ah

reverse engineering is quite niche knowledge

i know

and ppl usually dont teach

but i wont tell

xd

why

15:52

bruh

Lol

but the thing is

15:52

why u want offsets at all

15:52

just modify the source code

true

to do a deeplearning bot on ddnet for a school project

for example

xdd

a tip

he doesnt know what open source means

finish a gores map

15:53

by itself

its heavily system dependent so u have to figure it out, depending on windows or linux

15:54

find the program base address in code

Jupstar ✪

he doesnt know what open source means

he know xd

then

15:54

the variable u want

he probably uses a pre compiled bot client

and its a simple substraction

15:54

this is the easy way, using the source code

Jupstar ✪

he probably uses a pre compiled bot client

what u usually do to start is try to understnand how strings inside the binary are used

there is a thing that can make it even harder

15:57

i think its some register allocation thing

then u can guess first function names

zogitb: Memory offsets are changing runtime

automatic register allocation iirc

BTW I've done something similar but didn't got very far (because of no dgpu). I didn't use memory offsets just source code ;)

[ddnet/ddnet] Issue opened: #7226 Add our own buffering for Windows file I/O

We are not using the internal buffer for I/O on Windows anymore due to #6937. Although no problems have been reported yet, it seems like a good idea to do our own buffering to avoid too many ReadFile/WriteFile calls. An analysis of the I/O operations showed that the number of writes has increased severely due to removing the buffer:

Saving large map file:

Without buffer: 3500 writes

With buffer: 379 writes

Using values of 8192 or larger for snd_buffer_size will result in noticeable audio delays, for example for gun sounds.

GitHub

Click to see attachment 🖼️

@Robyt3 why is that a bug?

18:40

isnt that the idea behind a snd buffer

Jupstar ✪

@Robyt3 why is that a bug?

Hmm, maybe that's right, but why would we allow so large values then

if u do sampling rate of 192000 it should make it faster again

18:41

at least that's how i imagine it

I just noticed that I had a large buffer size and that's were the audio delay was coming from, seems like I accidentally set the buffer size

Jupstar ✪

if u do sampling rate of 192000 it should make it faster again

I see, that works. We should probably document that better

or maybe the former should be set based on the other

18:44

and remove the config

i dunno

18:51

it also depends on the audio driver i guess

18:51

i dunno how exactly SDL decides to do it

18:51

we should at least check if it's good to just depent on each other

18:52

if in theory u have a very very slow audio device, it would maybe need a much bigger buffer. except windows etc. do extra buffering

buffer size is an option because some computers can't fill smaller buffers fast enough
