i think it tries to set the format to DSD_U32_BE

07:13

can i somehow force the format to be S32_LE?

Wdym? If I understand correctly then that would be the moment you send the team members to the client. Correct?

From client or serverside?

@Learath2 Thursday for vulkan Did you already learn about subpass dependencies?

@Learath2 Thursday for vulkan Did you already learn about subpass dependencies?

I have one in my triangle renderer to delay the color output stage until I have an image to output to

09:41

I honestly don't really know what else I'd use one for now

vulkan

09:42

im going for 100wpm at 100% accuracy on monkeytype english 1k

09:42

gotta type faster

09:42

i wonder if i can do it in vr

09:42

that would be fun

09:44

closest i got was 98/97%

09:45

but it's just going downhill now

09:50

the data backs me up'

Image attachment

09:50

i get worse as i type

Ewan

i get worse as i type

Is this just for this session? I experience this for everything I do. My first few attempts will be decent but obviously warming up, then I'll perform very well for an attempt or two. Only downwards after that

maybe i need to become a kernel hacker

yeah just the session

09:52

i just did 1k

Learath2

You will need them if u have multiple render passes or multiple subpasses. IMO they are probably the hardest topic in vulkan. U need to understand basically everything u need to know about parallelization in computers + graphic cards + it's a super unintuitive design. On CPUs you would never work with flags to describe memory operation orders. And also not all memory flags will work with all pipeline flags

I wonder if this is a common human thing.

probably

The main idea is to hold up the pipeline until another subpass is done, right?

Well kind of xd

09:54

The pipeline is always there

09:54

It's more about the order of commands inside it

Well yes. That's what I was talking about. Good enough until I have a need for it

I honestly still shot myself often when I think about it. It's just that if you FCK up, you can easily crash your gpu . and it's also not very easy to debug and test out since u always need the full back end started to see if it worked

09:58

Synchronization layers defs help here

09:58

But even then I still often have to read the spec to fully understand the problem

09:59

https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VkAccessFlagBits.html Table 1.

09:59

Something u should keep in mind xd

10:01

Ofc it also depends on how tryhard u want to optimize

10:01

You can often just lock the whole pipeline and it works xd

... just become a riot employee and fix the client lol (edited)

i've read about a story of a person that used a software and reported a single bug for years, after them not fixing it he applied for the company, got hired, fixed the bug, and handed in his notice immediatly after (edited)

idk if its true but its such a gigachad moment

if you need to fix a bug that badly, then it must be worth more, than your current job

hi everyone i need to write external program which makes some actions on DDNet/Teeworlds server (for example, banning VPN players) is there any better solution to server communication than econ? any low-level protocol?

13:45

patching server source code will take a long time for every server type i have

fifo ig

it's no better than econ, i hate parsing human-readable stuff

13:48

my current software is a wheelchair full of regexes for every server type

well either econ or fifo it is tbh (edited)

what is fifo?

:D i had that question aswell 2 weeks a go "file input /output" it allows sending external commands to your client ddnet creates a fifo server on startup: which you can then send commands to through a fifo client

Image attachment

13:51

sending "echo hello" to the fifo pipe, will execute that command

oh, i thought you meant different fifo

13:51

but... is it any different from econ?

DDNet uses DNSBL

(edited)

13:53

I wouldnt recommend doing it via FIFO

i understood it as a way to send multiple different commands to the server - but using a "i googled the name": "DNS-based Blackhole List" surely sounds like the way to go for ban/blocklists (edited)

Avolicious

I wouldnt recommend doing it via FIFO

it is the reason i'm searching better solution i already have some stuff made with econ, and i hate it

xbt573

it is the reason i'm searching better solution i already have some stuff made with econ, and i hate it

DNSBL

13:59

It works and is built on top of the most tested and used protocol out there

vpn is only an example, i have other usecases

Whats the use-case?

Avolicious

It works and is built on top of the most tested and used protocol out there

oh, it's not dns based blackhole list?

xbt573

oh, it's not dns based blackhole list?

It is, but its based on DNS

13:59

DNS is heavily tested every day

13:59

it works

would be horrible if not tbh XD

Avolicious

Whats the use-case?

telegram/discord bridge, player data (nickname/version/ip address) accounting, message broadcaster

xbt573

telegram/discord bridge, player data (nickname/version/ip address) accounting, message broadcaster

You need a mix then

damn, feels like a project i could get workin on at some point

We are using gRPC for this

14:01

But its currently not built into DDNet

another problem is i have different server types/flavors, like ddnet, vanilla teeworlds, fng, teeware, etc.

14:02

hard to put into every source code tree (edited)

gRPC

14:03

vanilla teeworlds wont accept the change tho

14:03

fng dont know

14:03

teeware, i doubt

14:04

ddnet most likely

Hey there, i mostly got used to the Serverbrowser update and prefer it, but there is one thing that became kinda annoying. Before the update i could swap to the internet tab and look at my friendlist to see if anyone is online at all. Now with just one tab and one filter, i have to reset all filters(communities, countries, types) to get that information. Within the Friendlist there are three Categories(Online Players, Online Clanmates, Offline). I could also imagine that something call...

[ddnet/ddnet] Pull request opened: #8035 Always build switch entities layers

Only building the switch entities layer when the current map has a switch layer (#8011) also does not work, because the entities textures are cached for each type and not reloaded unless the entities are changed manually. First joining a server with a map that does not have a switch layer will cause the textures for the type of that server to be built without the switch entities layer, so the switch entities texture will be missing when joining a server of that type with a map that does have ...

[ddnet/ddnet] Issue opened: #8036 Line input rendering causes memory usage to keep increasing with Vulkan

While a line input is rendered (e.g. when the console/chat is open) (i.e. when the CLineInput::Render function is called), the memory usage shown in Windows' task manager keeps increasing. It goes down again when the line input stops being rendered (e.g. when the console/chat is closed). It appears that all free operations are combined into one frame so this can also cause large lag spikes when the console is opened for a long time, then closed and opened again. This only happens with...

985a230 Update BRA servers - def-

@Miguilim: maybe worth to mention next to your snap crc pseudocode is that C++ has integer overflows. So it’s just adding values to some integer if the snap is too big that might overflow. If you take the same code to other languages it might not overflow in the same way. But I’m not super sure here. It’s just something someone mentioned in the #developer channel once iirc. I do not know if snaps can even be big enough for that. Maybe it’s worth it to test the crc code with the same high values in C vs python, JavaScript and rust etc

Replying to @xbt573 hi everyone […]

What’s wrong with Econ? It’s the most portable and works across hosts. FIFO only works for ddnet and if you are on the same server.

problem with econ is that the output is interleaved, so spotting the output to your commands is rather annoying
