@Chairn: too bad that it changes the axis values :D

08:51

(atleast for the histograms)

@deen: did you happen to read it, or did it get lost in the amount of pings your receive per day :D

btw @deen i made the surface creation single threaded now, maybe you can test if thats enough also i'd like to know what steps are required to find vulkan under macos, i added the pkg config in FindVulkan, but i dunno if i have to search for moltenVK instead or smth

Read it, but forgot. What branch?

pr_vulkan

09:08

oh and you need -DVULKAN=ON now

figured that out already

[ddnet/ddnet] Issue opened: #4679 Something Wrong in Game Layer

I made a DDNet map and start it on server Server tips some wrong in the game layer and report this to here I checked the code about this tip but I still don't know why I can upload the map if need

ok, works with https://github.com/def-/ddnet/commit/239603a9f414d218f8d70ca0ee345a095c5027e0 but now only reaches vsync fps, even though vsync is off

Running on macOS · def-/ddnet@239603a

yeah i tried to change the value in GetNumberOfSwapImages in backend_vulkan.cpp for macos

09:16

hoped it could fix the FPS problem(read the issues on moltenVK) but apparently not

09:16

oh but it doesnt require the WaitForIdle hack?

Don't know, just tried it to see if that helps with fps

oh ok :D

09:20

ok thanks for testing, maybe apple or moltenvk make an update some day, already good it's working

this checksum.cpp is really annoying, increases build time quite alot while debugging, can it be disabled for debugging?

you should be compiling with -DDEV=ON

11:51

(anyway, even before this change)

11:52

(together with -DCMAKE_BUILD_TYPE=Release, if you want an optimized build)

11:52

-DDEV=OFF (the default) is for packagers and people who want to install the game

what is the advantage of it, i like to do as less changes to environment as possible

less stuff is built by default (the tools aren't), and checksum stuff isn't as comprehensive

could we default DEV=ON for Debug build?

i mean there is CMAKE_BUILD_TYPE=Debug, why cant it detect that instead

I'd prefer not to make features dependent on optimization level

11:54

that sounds like hard-to-debug bugs

mh ok, well my GUI exposes build targets and build type, so would be easier, but guess i have to add this to all ddnet repos i have locally :D

11:55

workspaces*

I'm not seeing any disproportionate slowdown. (cmake -DCMAKE_BUILD_TYPE=Debug -GNinja -DPREFER_BUNDLED_LIBS=OFF -DVIDEORECORDER=ON . && ninja)

incremental builds get slower because you always generate and compile checksum.cpp

But checksum.cpp build takes 84 ms for me, seems negligible

11:57

84 ms for generation, 50 ms for compilation actually

it takes most time for me when changing single lines or stuff

11:58

but anyway DEV=ON is fine

how do you generate this graph @deen?

the blue and green parts are the checksum. Why can ui.cpp only start building when checksum.cpp is generated?

good question

can't find a dependency in cmakelists

probably more related: https://gitlab.kitware.com/cmake/cmake/-/issues/21673

@deen can you check whether the problem goes away if you set(CMAKE_OPTIMIZE_DEPENDENCIES 1) at the top of the CMakeLists.txt? (not the proper fix in case it works)

14:10

reading through the issue tracker a bit more, it looks like this is an unrelated feature

@Chairn: too bad that it changes the axis values :D

plt.set_xlim(min, max) plt.set_ylim(min, max) You can use None, to keep the current value and change only min or max (edited)

I tried that, didn't help

@Chairn:

Traceback (most recent call last):
  File "/home/jupeyy/Schreibtisch/Teeworlds/DDNet/ddnet_jupeyy/build_rel/logs/./getimg.py", line 27, in <module>
    plt.set_xlim(None, None)
AttributeError: module 'matplotlib.pyplot' has no attribute 'set_xlim'

just xlim actually

ah yeah

matplotlib is not the most consistent library i saw

just found it on gogole xd

depending on the object types, sometimes it's set_blabla, sometimes just blabla...

it basically mirrors matlab in my experience

ah you even set ylim, ez as that :D

TabError: inconsistent use of tabs and spaces in indentation most annoying part about python xD

heinrich5991

it basically mirrors matlab in my experience

isn't it the other way around?

no, I don't think so

15:31

matlab must be really old

15:31

first appeared: late 1970s

yeah, more than 20 years, but matlab was just some blas library and plot library bundled all together at the start

matplotlib: 2003

hum, okay

use a real editor

from Matplotlib, Wikipedia:

Pyplot is a Matplotlib module which provides a MATLAB-like interface.[11] Matplotlib is designed to be as usable as MATLAB, with the ability to use Python, and the advantage of being free and open-source.

thanks :D

15:33

multithreaded vulkan overall has the straightest line

can you try retrofitting a gaussian on the histogram or compute variance and kurtosis?

what does the checksum stuff do?

Also, based on the previous figure, all your samples have different lengths (edited)

verify the integrity of what?

15:37

@Chairn r u a data analyst?

15:37

xd

@Chairn I think that's called "moment"

https://docs.scipy.org/doc/scipy-1.8.0/html-scipyorg/reference/generated/scipy.stats.moment.html#scipy.stats.moment

@Chairn: no im too dumb to use python xd and yeah, but i think its like zooming into a specific section, so maybe still ok
