Test(const string& str1, bool flag=false);
Test(const string& str1, const string& str2, bool flag=false)

which one will this call?

Test("foo", "bar");

@Ewan

10:24

no googling

10:25

the fact u cant answer instantly (i saw u type)

10:25

shows why rust explicitness is better

I’m trying to parse it

10:25

i just figured out it’s a function overload

it didnt look like code

Image attachment

lol mobile sucks

10:26

Image attachment

it could reasonably call either

nope

10:26

it will call the first

10:27

because char is implicitly converted to bool

10:27

const char *

10:27

ding ding ding

10:27

rust wins

what

poggers2

rust has no implicit casts

xd

10:27

wats that gif

gif of disappointment

10:28

i though it would call 2nd

ofc everyone would think at first glance

10:28

i did too xd

10:29

but a literal "sdfdsf"

10:29

is not a string

10:29

so const char * is casted to bool

https://stackoverflow.com/questions/32253788/c-wrong-constructor-being-called

C++ wrong constructor being called

I expect the code below to print Test::Test(string,string,bool), however it prints Test::Test(string,bool). Why does it call the constructor that takes only one string parameter when two are provid...

10:29

 

The type of the argument being used to construct Test is char const[4].

char const[4] decays to char const*, and has to be converted to a bool or a std::string const& to make the function call unambiguous.

A pointer can be converted to bool using standard conversion rules.

A char const* can be converted to std::string const& using a user defined conversion rule.

Given that, the conversion from char const*, a pointer, to bool is considered a better match than the conversion from char const* to std::string const&.

Hence, the call resolves to the first constructor.

thanks god there's no such thing in js land santatrollet

ah yes, another feature that makes your life ""easier""

11:05

i honestly dont understand what made people think that automatic casting is any good

Implicit. I find casts to bool usually pretty usefull

where all the functions is called in server/gamemode/DDrace.cpp ?

11:52

i don't get it

11:53

who call them every tick and on tile triggering ?

11:59

i feel stupid

CGameContext's property called m_pController call all those fucntions (edited)

12:00

no?

pepeW

Are the server types given by the ddnet server register or are they client dependent?

Register

12:45

But color client side

@deen: would it be possible to fund an Indonesian ddnet instance?

13:05

Hmm or how high is the Singapur server ping in Bali?

howhighru

@fokkonaut i survived him but u didnt :p

i did

13:09

i was scared tho

xd

fokkonaut

i did

not ur img tho

i sacrifised it

to be alive

chillerdragon

Hmm or how high is the Singapur server ping in Bali?

ping from jakarta to singapore ddnet server is 20ish, from bali would probably be about 30-40

ah nice that seems okay i guess

13:22

@Meeu where do you play from? o.O

jakarta

13:23

are u in indonesia chiller? :o

nice and you just casually happend to lurk in #developer? i never saw ur name

i lurk here from time to time xd

@Meeu not yet but currently looks like i will be in bali for a year starting january

nice, have fun!

gotta make sure i can at least do some ddnet gaming from my laptop

rust has no implicit casts

neither has c++, a cast is always explicit. Did you mean »conversion«?

14:03

and it's obvious which overload is chosen

Fussel

neither has c++, a cast is always explicit. Did you mean »conversion«?

seems like potato potato

14:05

it's clear what they meant

14:05

even if not using the C++-specific terms

rekt

kek

@heinrich5991 I don't have a problem with this in general, but I do have a problem with "rust is better than c++" guys obviously not knowing much about c++

(edited)

in this particular example, I also found it very nonobvious which function would be called

14:08

I only guessed the right one because the question was asked at all (edited)

Fussel

@heinrich5991 I don't have a problem with this in general, but I do have a problem with "rust is better than c++" guys obviously not knowing much about c++

(edited)

and I don't know why you question people's C++ skills. I think most people in this channel are pretty familiar with C++

Fussel

@heinrich5991 I don't have a problem with this in general, but I do have a problem with "rust is better than c++" guys obviously not knowing much about c++

(edited)

@Fussel btw, do you know rust? Like did you code at least 10k lines in it?

familiar enough to confuse cast and conversion

oh come on, that's just stupid

@Jupstar ✪ you wouldn't have found me to talk much about rust details, right?

you can use whatever words you want, you're not bound by the C++ standard

Fussel

@Jupstar ✪ you wouldn't have found me to talk much about rust details, right?

Well I literally was just curious^^

apparently boost even has a boost::implicit_cast btw

Learath also knows rust even tho he doesnt act like that mostly

so it seems that the wording is actually accepted in the the C++ community

you could say Learath got rusty in coding

question time. whats the difference between conversation and cast

conversion*

exactly (edited)

apparently @Fussel makes the distinction at "cast" being an explicit type conversion and "conversion" being an implicit one

14:13

here's a wikipedia article using these more or less interchangeably: https://en.wikipedia.org/wiki/Type_conversion

Type conversion

In computer science, type conversion, type casting, type coercion, and type juggling are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa. Type conversions can take advantage of certa...

14:13

In the C family of languages and ALGOL 68, the word cast typically refers to an explicit type conversion (as opposed to an implicit conversion), causing some ambiguity about whether this is a re-interpretation of a bit-pattern or a real data representation conversion.

14:14

ah, maybe that's where they're coming from

So the right term is implicit type conversion, and we can all continue living.

in C++

14:14

if you're talking about multiple languages at once, it becomes less obvious

Well since rust doesn't have it, there is also no name for it

rust also has it

14:15

let me remember what it's called there

Since he didn't actively mention cpp, one has to read in context anyway

Conversion and cast have some semantic differences but a lot of non pedantic people use them interchangeably

(e.g. from &Vec<u8> to &[u8]) (edited)

14:16

(or from &'static str to &'a str)

Isn't the first deref

it's called coercion in rust

Ok

Semantic isn't even the right word. It's like just terminology

14:18

Casting causes an explicit conversion

Jupstar ✪

Isn't the first deref

Deref can allow for coercions, yes

Anyway my brain won't remember the word coercion. Very hard xd

and in the first case, it's what happens

14:19

it allows you to pass a &Vec<u8> to a function that expects a &[u8]

14:20

ah, and [u8; 64] to [u8]

14:20

and ! to anything ^^

deref coercion

14:21

but its also why deref should only be used forsmart pointers iirc

14:21

anyway its not as invasive in rust imho

So coercions are kind of a try and error by compiler xd Just without losing context like with implicit conversion

also no overloads

Ryozuki

but its also why deref should only be used forsmart pointers iirc

I already send u the commit that changed the doc

okay, let's conclude: I'm wrong because I'm right *shrug* (edited)

Thursday new C++ day?

Jupstar ✪

I already send u the commit that changed the doc

oh xd

Fussel

okay, let's conclude: I'm wrong because I'm right *shrug* (edited)

You aren't wrong at all. But you are pendetic. It was clear in this context. But i agree that yours would be the most clear one

heinrich5991

it allows you to pass a &Vec<u8> to a function that expects a &[u8]

one question, in rust this deref is coded somewhere, as a trait, in c++ is it coded somewhere or is it done internally by the compiler?

Fussel

okay, let's conclude: I'm wrong because I'm right *shrug* (edited)

You are not wrong about the C++. Judging someones knowledge of a language because they don't know a minute detail in the terminology is what is not quite right

Ryozuki

one question, in rust this deref is coded somewhere, as a trait, in c++ is it coded somewhere or is it done internally by the compiler?

Cpp has smth similar to deref too

14:23

Operator overloading with specific return types

Ryozuki

one question, in rust this deref is coded somewhere, as a trait, in c++ is it coded somewhere or is it done internally by the compiler?

you can add implicit conversions in C++, by using a single-parameter constructor (and forgetting to add explicit) or by using operator int() where int is the target type

but the conversion from my code

both rust and C++ have a number of built-in conversions

which already comes "by default

14:25

"

14:25

ah its builtin ok

14:25

what are rust builtin conversions?

Ryozuki

https://doc.rust-lang.org/src/alloc/vec/mod.rs.html#3104

as_ref is entirely non-magical. it's just a normal trait

yep, that one is the magic one that allows the implicit type conversion between &Vec<u8> and &[u8]

@Jupstar ✪ is the doc update rly in? i still see the warning in docs

14:28

i guess its nightly

heinrich5991

and ! to anything ^^

we cant use ! in stable right

14:29

never type

14:29

i know i used it for functions that dont terminate

only as a function return type

yeah

you also use it implicitly when you use break, return, continue, etc.

14:31

fn get_integer() -> i32 {
    return return return return return!!!!!!!!!11111;
}

Ryozuki

@Jupstar ✪ is the doc update rly in? i still see the warning in docs

Yeah it's nightly. But it's widely used out side of standard

14:33

So they made it less confusing

14:33

And imo makes sense xd

yes

heinrich5991

fn get_integer() -> i32 {
    return return return return return!!!!!!!!!11111;
}

funny

[ddnet/ddnet] Issue opened: #7689 Add details back to sound layers again

heinrich5991

fn get_integer() -> i32 {
    return return return return return!!!!!!!!!11111;
}

can u explain this snipped in detail

15:36

snippet

Ryozuki

can u explain this snipped in detail

It never returns never xd

15:42

Else it would be ever xddd

return {
return {
return {
  return !!!!!!!111111;
}
}
}

15:43

is it equivalent to this?

15:43

! in rust also means bitwise not

Yeah

15:44

I think he just wanted to show the conversion

Ryozuki

we cant use ! in stable right

@Ryozuki what are use cases except as return type btw?

@Jupstar ✪ the function running a infinite loop in bare metal

15:46

fn a() -> ! {
  loop {}
}

15:46

15:47

Another possible use would be a wrapper around the Unix exec family of functions, in which the current process is replaced with the one being executed.

15:47

s a full-fledged type, it can be used in more contexts, such as in Result<T, !> indicating a result that can never fail, or Result<!, E> as one that can never succeed. These are useful in generic contexts; if you have some trait that requires a method to return a result, but for that particular implementation it can only possibly succeed, you don't need to fill in some dummy error type.

15:48

pub fn exit(code: i32) -> !

15:49

would be rust equivalent of exit

15:49

or

15:49

making ur panic handler

15:49

#![panic_handler]
fn panic(_info: &PanicInfo) -> ! {
    loop{}
}

heinrich5991

you also use it implicitly when you use break, return, continue, etc.

Could you explain why it was done like that? I mean i understand that this makes sense, in a way that it doesn't break any logic. But it's kinda weird xd

Jupstar ✪

it makes sense for macros

15:50

like todo!

15:50

it works on any return type

15:50

thanks to that iirc

Ryozuki

it makes sense for macros

I meant that the syntax even allows multiple returns

15:51

Like i understand that it simply adds a never type here

15:51

But dunno xd

gg i am locked out of paypal because i provided fake data

15:53

15:53

i wonder why quitting vim is a meme but nano isnt xd. Quitting nano is so hard.

15:53

:x vs ctrl+x y ENTER

Isn't there like a panel at the bottom which shows possible shortcuts

ou so at least you know what to do

15:54

okay i see

I used it once

15:54

During installation of gentoo

15:54

Xd

a user new to linux does not understand ^X Exit

15:55

not sure how much help that is

15:55

vim even tells you what to do when you press ctrl+c while nano does not

Then closing the terminal would be the easiest

imo quitting nano should be established as meme

chillerdragon: do u use tmux?

The paypal spies hunt you

DDNet's server process is multicore or it's single core?

mostly single core

16:28

single threaded to be precise

I getting some spike high CPU usage on more than 200 players

16:30

is it normal ?

that sounds pretty normal yes

16:30

besides the physics, it must also process all packets for all players etc

16:31

but it depends on:

are all on one server
how good is your VPS?

it's show a bit higher ping in servers with more players like 60 players but in other ports with lower player it's fine

thats normal

16:44

need good single core performance

17:14

somehow i conviced him i am legit and i got my 5 bucks back poggies

17:19

@Jupstar ✪ yo btw how do you handle security questions? i mean the legacy 2fa where they ask for maiden name of grandma and shit. I always use pw generator for that. Its so funny when some dude asks you on the phone "in what city or town did your parents meet?" and you go "g6">QM5%Kq;["

i once couldnt enter my acc, bcs my phone number changed. the support just changed it without any verfication at all xdd

sus

i use keypass

17:21

keepass

also for moms maiden name?

i was never asked that xD

yea its not that wide spread anymore

17:22

different generation

only thing i once used as verification was name of my first school

ye but did you put actual school name?

oh nvm, I'm saying shit then

it would work if i hadn't skipped playing for 2 years

that date is probably when they starting keeping track of hours ig

yea could be

Mhm, data has only been collected since 2021-05-18. Here https://ddstats.qwik.space/player/Boci/playtime, you can find some more detailed stats, but it's still quite futile.
