Hi

Hi

how r u?

Hey

Hi

04:26

how r u?

welcome

04:26

what are u selling

ewan

hi

male or female?

how r u?

male and well how about urself

هعی

true

male too

male بدرد نمیخوره

male 3

فارسی بلدی؟

r u coder?

somewhat

someone

04:27

not somewhat

can u teach me how to manipulate ddnet source code?

where did you studying english?

from where should I start?

from the int main

04:28

ha ha ha

:D

Moein: i can help u but u need to be more specific

04:28

Kourosh: wdym

I mean are you C++ programmer buddy?

yes

wow

04:29

it's great

very nice, I want to make it somewhat that connects to my api and for example at each round give the winners

04:29

and their score

u want to submit game scores to your api?

Exactly

04:30

احسنتم

yes

what kind of api is it

Good API

[ddnet-maps:master] 1 new commit

318edd7 R Good Movement - ddnet-maps

python API

04:30

Flask API

flask for example

but it's http?

Yes.. HTTP

04:30

or HTTPS

it can be

cool

04:30

should be easy enough

So explain to us

04:30

please

04:30

If you explain we will pay you

04:31

We will give you 1,000,000 ريال

put your wallet address too bro

ddnet already comes equipped with libcurl, all u have to do is read libcurl api docs to send http requests

Really?

04:32

Imean جدی میفرمایید؟

yeah, u can look up examples on stack overflow

Would you please give us link?

which part of the code should I read?

04:32

because the code I've downloaded

https://stackoverflow.com/questions/51317221/how-to-use-libcurl-in-c-to-send-a-post-request-and-receive-it

had many parts

04:33

and it was peculiar for me to dig into it

ddnet does have a pretty elaborate codebase

You know

04:33

we wanna know

04:33

where in the c source code

04:33

should we add the code of libcurl or someshit like that

04:35

Hey?Ewan?

04:35

BUZZZZZZZZZZZZZZ

look at engine/shared/http.cpp

Wow

04:35

really?

yeah

Let us see

04:36

Would you please clarify where in this code?

anywhere you see curl_ function calls i guess

Specify which function if it's possible.

yes, cause it has many functions, Which function calls at the end of each round

you'd mainly be doing something like this though

        const char *data = "submit = 1";

        curl_easy_setopt(curl, CURLOPT_URL, "http://10.5.10.200/website/WebFrontend/backend/posttest.php");

        /* size of the POST data */
        curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, 10L);

        /* pass in a pointer to the data - libcurl will not copy */
        curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);

        curl_easy_perform(curl);

this is from the stackoverflow answer i posted earlier

04:37

using the curl_easy interface it's very trivial to send http requests

04:38

you ought to look at the answer code instead of the question though they may have better wistom :^)

04:38

wisdom

You know let me say exactly what we wanna do... we have an api and wanna run some competition and need to start a game and get the game's result.

do you know how to use your API for this if you were just sending example data

04:40

i can't really help you further without doing it for you

I jus wanna send game data to some api

04:41

If it's true then please do it for us

what part of that can't you do

04:41

you will really have to be more specific

Don't know where in the code should we add the code that sends the data to our api.

we want to start competions, in our server, after each round all of the servers should send game results ( First, Second, Third Player, ... and their score), now we want to know that from which part of the code of ddnet source

you want it to happen at the end of every game?

can give us these results

Yes

04:42

Exactly

let me see

at the end of every game

04:42

Thanks buddy

see CGameTeams::OnFinish

04:45

you can see how all of the data is collected and sent to the client so it can be shown on their statboard

where Ewan

04:46

where

04:46

where in the code?

04:46

Which file, which line, which function?

in ddnet this is in game/server/teams.cpp

04:46

i told you which function

04:46

void CGameTeams::OnFinish(CPlayer *Player, float Time, const char *pTimestamp);

where

but i am sending u info for ddnet server

04:47

which is the race mode

04:47

and i think u want pvp

04:47

but idk what server you're basing yours off of

Morning

gm

<ChillerDragon> mornin

hi chiller

<ChillerDragon> uwun

can u direct these charming fellows to the spot in the game server code where the match ends

04:49

on some pvp

04:51

Couldn't understand

what do you mean?

Basketball?

you will have to modify all of these game modes individually to get it to work in them

<ChillerDragon> did u ever play basketball @MilkeeyCat ?

ChillerDragon: Shutup

chillerdragon: a few times and once got hit by the ball in my face

<ChillerDragon> omg not irl

04:52

we have a important question

I don't even know if this mode exists lmao

what the fuck are you talking about

<ChillerDragon> thats what i thought @MilkeeyCat

04:53

<ChillerDragon> i don't think there are any servers anymore

04:53

<ChillerDragon> when did u start playing tw @MilkeeyCat ?

ChillerDragon: You are definitely an idiot

First Finish 08.09.2020

<ChillerDragon> eww ddracer

Me new

<ChillerDragon> yea likely u never had the chance to play basketball

I wish i found ddnet earlier

04:54

It had some cool ass vibe before

<ChillerDragon> don't forget the time before ddnet hehe

(saw it from aoe vids)

<ChillerDragon> i used some goofy ddrace client (not ddnet) on my old macbook :D

Average chillerdragon moment

anyone there

04:56

?

<ChillerDragon> hi

04:56

<ChillerDragon> we are still waiting for your response

from where can I obtain fng scores at the end of each round?

<ChillerDragon> from ewans question

04:56

<ChillerDragon> which code base are you currently working in

nothing yet, we want to chose

04:57

please guide us

04:57

:')

<ChillerDragon> i think jopstis fng is best

<ChillerDragon> it took me 5mins to add multi processing to the bash script and i spent hours on porting the same code to python

06:48

<ChillerDragon> its literally one character in bash to go blazingly fast on all cpu cores

[ddnet/ddnet] Pull request opened: #8196 Update gtest to current main branch

I just ran into https://github.com/google/googletest/issues/4206 and realized that it is fixed on the main branch and google also recommends to use the main branch. From their readme

GoogleTest now follows the Abseil Live at Head philosophy. We recommend updating to the latest commit in the main branch as often as possible. We do publish occasional semantic versions, tagged with v${major}.${minor}.${patch} (e.g. v1.14.0).

<ChillerDragon> I wonder what the goal of xz was. Maybe it wasnt a state actor but it was a 12yo kid who tried to ssh into one specific pentagon server. And decided adding a vulernability into ALL ssh servers was the easiest approach given he had 8 hours to kill every day anyways skipping school

What do you think about multilevel inline if statements?

10:33

Very dirty imo

Teero

What do you think about multilevel inline if statements?

multilevel inline if? like the condition spanning multiple lines?

I mean smth like int a = b >= 63 ? 0 : (c <= 0 ? 31 : 0)

Ah, ternaries. I don't like it if there is more than 2 and there aren't parens

And where is the logic of attaching a hook in scripts?

10:39

I'm lost.

Ah that's what you mean

gamecore.cpp is where most of it is at

      Making system calls can be slow.  In x86 32-bit systems, you can
       trigger a software interrupt (int $0x80) to tell the kernel you
       wish to make a system call.  However, this instruction is
       expensive: it goes through the full interrupt-handling paths in
       the processor's microcode as well as in the kernel.  Newer
       processors have faster (but backward incompatible) instructions
       to initiate system calls.  Rather than require the C library to
       figure out if this functionality is available at run time, the C
       library can use functions provided by the kernel in the vDSO.

       Note that the terminology can be confusing.  On x86 systems, the
       vDSO function used to determine the preferred method of making a
       system call is named "__kernel_vsyscall", but on x86-64, the term
       "vsyscall" also refers to an obsolete way to ask the kernel what
       time it is or what CPU the caller is on.

       One frequently used system call is gettimeofday(2).  This system
       call is called both directly by user-space applications as well
       as indirectly by the C library.  Think timestamps or timing loops
       or polling—all of these frequently need to know what time it is
       right now.  This information is also not secret—any application
       in any privilege mode (root or any unprivileged user) will get
       the same answer.  Thus the kernel arranges for the information
       required to answer this question to be placed in memory the
       process can access.  Now a call to gettimeofday(2) changes from a
       system call to a normal function call and a few memory accesses.

15:29

Looking at the hour and then doing the mental calculation 5*minute hand position + 0-4 is annoying I don't want to do math to read it

You don't do the calculation while reading it. Just by looking at it you instantly know

I can't do that

You can, just need to do it more

also i like the ticking sound

It's not instant for me, reading numbers is

Start by memorizing the landmarks, 0 up top, 15 to the right, 30 to bottom, 45 to left

minutes do kinda suck tho i agree

Then it's just a matter of how far to the left or right of the landmarks the minute hand is

Already more effort than reading two numbers

Ofc it is, there is a reason we made digital clocks

15:31

With that attitude yeah, I can see you never being able to do it

I can do it

15:33

I just don't want to

15:33

Anyway probably not a relevant debate here lol

You obviously can't, as if you could then you wouldn't need to do any math

analog is cooler. Otherwise we wouldn't have overpriced analog watches greenthing

greenthing

i doubt ppl buy 50k watches to know the time

expensive watches are more status symbols than anything
