<ChillerDragon> tw fame?

<ChillerDragon> the gpl they are talking about here what is it? Is the the license? https://forums.developer.nvidia.com/t/linux-6-7-3-545-29-06-550-40-07-error-modpost-gpl-incompatible-module-nvidia-ko-uses-gpl-only-symbol-rcu-read-lock/280908/55

The error occurred on my Debian 12 also well.

03:19

<ChillerDragon> did a fucking license break the nvidia compile during my debian update!?

<ChillerDragon> bruv kernel panic on boot. And debian is stable they said^^

<ChillerDragon> Yea so if there are any debian users here that have the nvidia package installed I recommend holding back updates for a while.

Really?

As soon as it gets the extended sever info

06:21

So in this case the master server script

06:22

But maybe Heinrich didn't add this

chillerdragon: had this at work yes

funny tho debian tells me it's a A1000, maybe it is (edited)

Teero

btw if you unplug your system while DDNet is running and DDNet does some storage action it freezes

well what do you expect it to do

Teero

how bad can the quality get? obs: yes

what encoder & settings are you using

07:27

can't really blame obs

07:28

libavcodec does all the heavy lifting as far as video encoding is concerned

Ewan

well what do you expect it to do

I expected storage not to stall the entire process when you're only running on memory

Ewan

what encoder & settings are you using

Yes myself was the issue

do u guys know how to make fng2 server without this ugly text in front of my server name

You need to recv the client extend serverinfo msg.

08:19

The client send a packet with NET_HEADER_EXTENDED

08:20

The packet like this mode

08:20

[NET_HEADER_EXTENDED] [Extra Data]

08:21

You need to get the extra data, and

08:22

analyze it

Are you planning to hard fork like ninslash or nodes?

Replying to @Mʎɹ シ Maybe this looks bad, but it looks fine to me. My first hud in lua xdd

is this client <-> server lua communication or is it just clientside lua binding baloney

The server sends the lua code its full on remote code execution axaxaxa

08:42

At least that’s what I understood from his previous message

Lmao

chillerdragon

Are you planning to hard fork like ninslash or nodes?

No, I think

08:47

Server is avaible for standard ddnet client

08:47

But custom client can receive lua code from server and execute

11:35

<ChillerDragon> ah wait no hmm

11:35

<ChillerDragon> ah yes it is chance

11:36

<ChillerDragon> if (time.time() - self.last_send_time) > 0.1: this seems to be the problem i assume

11:36

<ChillerDragon> last_send_time gets set on every packet send including keepalives

11:36

<4ipset> what is it

11:37

<ChillerDragon> you put all the if statements with your reply logic into the keep alive branch

<ChillerDragon> you wanna keep the keepalive

11:40

<ChillerDragon> just put your logic outside of the if statement like all the other if statements

11:41

<ChillerDragon> and lmao there is a bug in the parser my bad

11:42

<4ipset> the bot still cant write letters

Image attachment

he answers for a while and then stops

<ChillerDragon> oh and you overwrite msg

11:44

<ChillerDragon> wasnt a bug in my parser you just confused me

11:44

<ChillerDragon> you send a chat message and store it in msg =

11:44

<ChillerDragon> then you do a if statement based on msg as if it was a server sent message

12:03

only responds to my first message

<ChillerDragon> yes the message length calc is off

If you create a bot, either ask the server provider for their consent and mark it as bot

this is the server @4ipset

12:07

I'm the admin there

Fair enough. I was talking about a general process like that

12:08

If you are an admin you can approve yourself, but also mark it as bot, otherwise players might think that someone is on your server

<ChillerDragon> @VaLl yea im too lazy to fix that now but thats a bug on my end thanks for testing

avo is scarred by iF xD

I dont care about iF tbh

12:08

Its more the player experience

Avolicious

If you are an admin you can approve yourself, but also mark it as bot, otherwise players might think that someone is on your server

this is a temporary nickname until the bot is not fully operational yet

<ChillerDragon> oh i think its a pyson momemnt tbh

12:11

<ChillerDragon> where it remember last constructor arguments

12:11

<ChillerDragon> or something like that

You can also announce "is_player": false, in the HTTP register. But to do this you need to rewrite some code#

<ChillerDragon> @VaLl okay so for now you can only ever send the same message length. Or set msg.header.size manually but its a bit trappy. I will not fix it today but its on my todo now.

No it's down

it’s up right now

Where's up?

above me

You are standing sideways

definitely not

Ewan

above me

If you're a line and you take the normal at the height of your feet and then draw a 2d plane is it on the upper side or the other one (edited)

The moon is above me dude

Ah ok cool

12:47

What direction are you pointing in?

UP

Hmmm.

away from the gravitational pull we describe as DOWN

Woah cool so the moon is above me too?

12:49

Since it is not inside the planet?

It is in that direction

12:49

Below

12:49

Moon is down for u

What is moon for earth?

12:49

Below or up?

Depends on where you make the measurement

12:50

there is no objective up or down in space

12:50

you need an anchor of some kind

I believe the earth isn't perfectly circular so highest point is the head

Ok

*anchor (edited)

Not really

12:51

That’s not how anyone defines a head

12:51

It is the furthest point on a generally spherical mass

12:52

My toes are furthest out from my center of mass so they must be my head

Yea do the average of all points on the earth and then check which is furthest

Ewan

My toes are furthest out from my center of mass so they must be my head

That is the truth

12:53

Okay mount Everest with 8849m is the anchor

12:54

So where is the moon rn?

12:54

Above you?

12:54

If so we need to know where you are

It’s above me yes

12:54

Not you

12:54

It’s below you

12:55

Also not sure what furthest point has to do with it

So if we assume you are the moon and are represented as a 2d vector of angles pointing from the center of the earth (edited)

12:56

And I am the same but somewhere else where the moon is not above me

I’m Not the moon

12:56

I’m me

Ewan

I’m Not the moon

Since the moon is above you I can say you are the moon +-90°

No

12:58

The moon is above me because it’s night time

So in the current time you are almost the moon

12:58

+-90°

(edited)

I am not the moon

12:59

I’m not almost the moon

But in my head you are and you can do nothing against it

13:00

it doesn't even know what optimization is.... (edited)

18:15

and it can't find memory leaks ;( (edited)

i think both are wrong on x64 and on any high end cpu

18:43

or most desktop cpu

18:43

floating point division or multiplication implies 23 bits or 51 bits operation while integer one is 32 or 64

18:46

hmm, 3 or 4 cycles for integer ones, 5 cycles for floating point ones

18:46

https://www.agner.org/optimize/instruction_tables.pdf

18:47

(for haswell architecture, already quite old with jupstar's standard)

18:48

however, floating point division is faster (22-96 integer vs 10-24 for floating point)

but i guess it also depends on how exactly the calculations are used in a tight simd sceneraio ofc every cycle matters but if u mix calculations with other stuff (pointer acces etc.) the calculations are often offloaded to the floating point unit while other stuff happens simultaniously

does anyone have experience in analyzing discrete data?

19:18

I need to split the data into approximately the following intervals (segments with a beginning and an end time)

Image attachment

fft, retrieve main frequency, sample at the correct interval

19:33

you can also look at the derivative to detect sign changes

19:34

which is where this kind of stuff might occur

(but it's not 100%)

what you trying to achieve exactly?

Chairn

what you trying to achieve exactly?

determination of useful work based on the generic current of the press (edited)

shouldn't you try some computation and integration then ?

Chairn

shouldn't you try some computation and integration then ?

now a very stupid algorithm has been made, to consider everything above a certain value as useful work, this would be enough, but on different days this limit either rises or falls, such an algorithm is not suitable, a more universal one is needed

Chairn

fft, retrieve main frequency, sample at the correct interval

fft its Fast Fourier Transform ?

yes

19:38

but now, im not sure this is the way to go given your problem

Chairn

but now, im not sure this is the way to go given your problem

thanks, I'll study it

Matodor

determination of useful work based on the generic current of the press (edited)

"useful work" sounds hard to define, especially starting from just "current"

20:35

Current through a resistance creates power, how much of that power is useful to you? Can you even model this system as a resistance?

20:36

The intervals you marked roughly looks like just threshold comparisons, maybe with a bit of hysteresis (edited)

20:40

If you are having an issue with the thresholds changing, the slope of this graph looks very steep, maybe the derivative is more telling about when the machine is doing "useful work"

20:43

Another tip would be to discard the DC component, for which you can use the 0th component of the FFT, you'll just have to play around with a couple of these ideas until you find something that looks distinct enough
