probably not, they were many years ago. We could try changing it and see if anyone complains

would be nice to change it and test, as I said I haven't seen any weird behaviour, but maybe I'm just not using something, that could be bugged because of it

I hope this doesn't give a chance to cheat. We also reset practice when killing a team, so loading can be considered as similar to killing?

Mostly because we felt 64 people are enough, secondarily because 64 bits is the largest portably supported integer size. Beyond that we'd need to change our integer team masks and stuff into bitsets, which has performance implications. Furthermore the O(n^2) nature of some of the code starts to rear it's ugly head. Not that they cant be optimized but that we didn't think >64p is worth the effort

You dont need that for the masks tho

I have a very simple Mask128 header

10:18

@deen do you think 128 player is worth it, maybe not on all servers/maps but like back in time, simple down etc

10:19

I am unsure about the network traffic/clientside hardware issues with 128 players. On my server only 64 are sent, so its equally for the client

10:19

In an official ddnet client for 128 players that would change

waiting that heinrich comes back, ig vacation was good for him, he worked too much

10:33

what do you need from heinrich @ReiTW

nothing special, just want to discuss about that proxy thingy he talked about & also the https master ban

ah

10:34

good things

yes

10:39

for now I feel better with the new thing I've set up, but still that guy hosting vali's private BW server & lying, saying he doesn't know him, idk

It is 90% vali. He just talks the same way

10:44

No he is a genius

Martin is a new name. How would we ever figure it out?

ik wym

10:44

xd

10:44

Never

10:45

he is frustrated

10:45

since he cant ddos me anymore feelsamazingman

feelsamazingman

I'm surprised he is still interested in this game. A lot of old players disappeared and he is still here

Yea

10:46

When real life is sad i guess

We don't even engage with the guy so I have this feeling u and rei keep poking him back to life

You know that this fact is simply false

10:47

even when not talking to this guy for over a year he comes at least for the tournaments

10:48

So, i think its useless just "ignoring" him or avoiding to even talk about him or whatever

10:48

this guy has major brain damage and does this even when he doesnt get attention, so this is completely irrelevant imo (edited)

Learath2

Martin is a new name. How would we ever figure it out?

Martin is an old iF|City player

10:50

that's the problem

10:51

I doubt this is vali, but he didn't get vali's binary like this

he would talk to you if he hosted those servers

Learath2

I'm surprised he is still interested in this game. A lot of old players disappeared and he is still here

idk bro sometimes nothing happens & suddently we receive attacks

10:52

we don't even need to trigger vali lol

Ofc it's vali. He names his servers like vali, he has valis source, he talks like vali

xd

well I wouldn't say it's him directly but feel free to think it

it is him

Probably just took the old if city players name to fool people

but discord account is 2 years old & Insanity (from my team) knows this player

@ReiTW the way he talks identifies him so often

Hm, maybe vali has multiple personality disorder?

he also came with a 8 month discord acc on my Server

That would explain a lot you know

no clue, but I'm fine since I've implemented a website for whitelisting, sad that I have to get that far just for a game

xd

10:55

@ReiTW also: i wouldnt focus on the discord acc age that much

10:55

i know at least 3 accs of him anyways

but my server + XDP, when vali attacks a protected port, my server is just laughing at him

wouldnt be surprised if he had more

well dunno

ReiTW

but my server + XDP, when vali attacks a protected port, my server is just laughing at him

ye same

Learath2

That would explain a lot you know

bruh and that guy on teeworlds discord saying i'm against competition

10:57

how many people were hosting pepe or v3 & had some players, didn't care at all

10:57

even more I was playing on those servers & not bombay

yeah well for me it's not him, but as I said if he has BW binary or source, then vali is definetly behind all of that once again

11:03

good stuff

I'm a little on the fence about docker. It's a good idea but it has that weird corporate air to it

11:03

Proprietary but not of sorts

11:07

look at the description

11:07

People are now writing formal academic papers debunking Rust's lies about safety and the rest. The more I learn about how shitty and dishonest Rust is (and its community) the more motivated I am to look at C and C++ (again) and the more I'm not just ambivalent about Rust, I'm actively advocating against it. Rust is fucking bad for the world. There are still zero significant projects in Rust while there are now hundreds in Go including Kubernetes, Docker and the entire cloud native ecosystem. Rust is a fail. Die, die, die. Learn it and watch your career die with it.

11:07

[Update: https://www.techempower.com/benchmarks/ confirms Rust, C and C++ have the fastest web servers period. I was wrong about that (having remembered another study that only compared, PHP, Java, Erlang, Node, and Go). Go is next, but Go is the clear leader from the dozens of enterprise case studies porting from non-compiled web frameworks. In fact, I have yet to read a single case study of anyone using Rust for any web services in an enterprise environment.]

True, but we dont want this sound in ddnet anyways, i have the feeling

11:23

at least it wasnt there for years already

11:23

I think its not a big issue, we could also add the sound back in again. i dont think there was a reason to "remove" it

11:24

probably accident

was probably originally at the beginning of the function

(because the function is triggered again and again when you stand on the pickup) Wanted to share it also just to have something to laugh

I'll test it, how it sounds like when it is at the beginning of the function.

xdd

lol I think I have never heard that sound xD

11:31

sfx_pickup_ninja.wv

Its vanilla

I just tested a vanilla server, there is indeed the sound. no idea if we want it, it sounds not bad.

wait, the ninja pickup sound doesnt play in ddrace maps?

yes

11:41

it was already like this since 2011, so no idea

@deen do you think 128 player is worth it, maybe not on all servers/maps but like back in time, simple down etc

I think the community would appreciate it. But some effort, huge scoreboard etc

I could do it, but only the serverside i guess

So we'd keep 64 players in client for now and see how community likes it?

13:28

But I'm worried about CPU usage

13:28

some servers have 50% CPU usage with a single 64 player server, so they could start lagging with 128

13:29

So I might have to restrict some, similar to what I'm doing on CHN servers already

deen

So we'd keep 64 players in client for now and see how community likes it?

it should be a map setting maybe, so that maps like those big t0 maps can activate it

because i dont see any reason for "easy" maps to have it

fokkonaut

it should be a map setting maybe, so that maps like those big t0 maps can activate it

But whats the use-case for that?

hum, i haven't found any exception (try/catch) in the source code, are they forbidden? I know that threads and exception usually don't mix well together

exceptions bad

usually means u have forced vsync

i don't

20:12

i disabled it in both nvidia panel and application setting

probs in ur nvidia settings, or not exclusive fullscreen?

still got themessage

20:12

exclusive full screen

anyway it is what it is, you dont have immidiate mode, dunno why

alt-tabbing when client start crashes

20:16

swapchain failed: run out of memory

mhh, well nothing i can fix actually, the loading screen blocks all threads (edited)

20:17

it probs misses the SDL events

20:17

that would be required

20:18

would generally be nicer to poll SDL2 events during startup probably

20:19

@Chairn btw since ur GPU is old, can u try video rendering and screenshots?

20:19

i wanna know if that works correctly

key to screenshot works

Image attachment

good

this doesnt

Image attachment

20:22

in game screenshot

ah

20:22

rest in peace xD

20:22

but kinda looks cool

Chairn

key to screenshot works

so print screen works?

20:23

that's probs another proof that the windows compositor is active actually xD and not exclusive fullscreen

yeah, the imp. scr key on keyboard works for me

20:23

in game menu shows exclusive full screen

20:23

but i've heard that in windows, this doesn't mean that in reality

do you compile by source?

20:26

actually can also just look into GPUInfo.org

Jupstar ✪

do you compile by source?

uh no? i took the client from my pr with the default switch

20:27

that i rebased just before

20:29

any idea why the sound might be lower?

it was changed

20:30

ok your GPU doest have linear dst blitting for RGBA textures

20:30

maybe i can simulate and see if screenshots are broken bcs of that

wow, emotes are really more smooth now

20:32

did anything change?

yeah but long time ago

20:33

mh weird, for me even then screenshots work

i got the mailbox/fifo message regularly, it's normal?

everytime u alt tab

20:35

or resize

yup, everytime i alt tab

has nobody intel uhd 630 and is on linux xd

20:40

then we could just see what the validation layers say about screenshoting

20:41

but probs intel driver on linux are better anyway, why even bother xd

i wonder what i have on the work laptop

20:43

its intel 100%, no GPU, but dunno the version

20:43

should i test anything else?

any idea on the sound level changing?

20:53

is it because of the widening of the sound slider?

Wild idea: can we make proof of work part of the handshake in the protocol? Maybe not always, but once we (somehow) detect a DDoS?

20:57

Of course this only makes sense if the attacks on the servers mainly target the handshake, rather than overloading then networking stack in general

which handshake

when the client connects to a TW server

you mean that TKEN handshake? Didn't secured.gg already try & failed?

Chairn

any idea on the sound level changing?

it just simply reduced, bcs new players complained it was too load

No idea, I sadly don't follow development much, just an idea that sprung to mind while i was waiting for help after failing because of a DDoS

Chairn

should i test anything else?

well if everything except screenshot works, thats already a win ^^

well, i didn't find anything suspicious

strangly enough on a intel hd 550 graphics tablet everything worked without problems

Scrumplex

No idea, I sadly don't follow development much, just an idea that sprung to mind while i was waiting for help after failing because of a DDoS
