it seems like fixed point multiplication is kinda slow

18:22

in a sense that it seems to take multiple instructions

18:22

hard to tell really

18:22

without testing it

18:22

but

18:22

i see why people use floats lol

18:26

i guess it's two instructions

18:26

multiply and bit shift

Fixed point multiplication shouldn't be slow

idk

18:45

now i have to implement square root

18:46

to calculate distance

18:47

ChatGPT explains quite well how to do that

18:47

AI progress is really quick

18:47

i don't even have to tell it to think step by step

18:48

because now chain of thought is a part of the training process

18:49

AGI might be close actually

okay, fixed point sqrt is just finding the square root of an integer and then multiplying it by 256

18:59

math is so cool

18:59

this doesn't seem like it should work

18:59

but math doesn't lie

pilonpl

okay, fixed point sqrt is just finding the square root of an integer and then multiplying it by 256

*multiplying it by the power of two appropriate for where you placed the fixed point

19:22

and there's no shame in converting your fixed point to floating point for some calculations if it makes sense to do

19:22

I think the main place where fixed point is clearly superior is global coordinates

risu

and there's no shame in converting your fixed point to floating point for some calculations if it makes sense to do

i know

20:18

but i want this to be mathematically perfect

20:18

well, within the precision of my fixed point representation

i actually use doubles to print the fixed point number

20:26

beacuse it's the easiest way

This project is really enjoyable

pilonpl

beacuse it's the easiest way

write your own int to string conversion, actually really easy

20:53

and fun

I did write a string to int converter

20:55

Mostly for AoC

stdlib does do string to int so idk why you'd need to do that

Because it's useful for parsing input

20:57

So basically the function would take in char** as input

20:58

And just consume the whole number

20:58

Which would set the passed pointer to the first char after the number ended

20:58

Really convenient

20:58

Idk if stdlib can do that

ohh, ok then I get why you'd do that instead of just using the stdlib version

There are also way to many functions in stdlib

21:00

With comments like "this function should never be used" lol

You should see languages with actually extensive standard libraries

pilonpl

With comments like "this function should never be used" lol

oh nvm

The naming convention is also somehow bad

21:02

Lack of namespaces is a really big issue with C

21:02

Not because it matter that much in practice

21:02

But because i don't like it lol

21:05

I guess c++ is kinda cool in a sense that it's almost a C superset so you can still use C style with some little additions

21:06

Although it's kinda neat how strict C is (edited)

21:07

There is one way of doing things

21:07

In c++ you don't know what a + operator does

21:07

It might call a very expensive function

21:08

Where in c everything is explicit

I kinda like operator overloading but it should be more obvious

I mean yeah, it's not that big of a deal

maybe don't allow overloading normal operators like + but have special variants like .+ or something so it's still terse but is distinguishable

21:11

and generally it doesn't sound like a bad idea to restrict overloaded operators to pure functions

Also what if none of the predefined operations make sense for your use case? It's kinda weird to use a symbol for one operation but a full function call for another

some languages allow all sortsa wacky operators

Yeah i guess but it's weird

Discord?

Huh

Discord just stopped working for a few minutes

Lol

Probably not a worldwide issue

pilonpl

it's like that joke that 1 hour without electricity would bring us to insanity

only for those that only know internet

The world's economy would collapse immediately lol

pilonpl

Yeah i guess but it's weird

ok so now that Discord works again there are actually some languages that allow you to make any binary function an infix operator

21:30

and you can use funny function names like :) (maybe probably idk) (I'm sure there's a language where you can make :) an infix operator)

Kotlin mentioned!!!!

pilonpl

The world's economy would collapse immediately lol

well yes everything electronic will fail

21:31

but the people themselves wouldn't go insane

meloƞ

Can you make :) an operator in Kotlin? I wanna do this now

Cammodude

but the people themselves wouldn't go insane

Well coding would be much harder without the internet

21:32

And how would i update my archlinux system

I don't think you could directly, but you may be able to do it with backticks

perfect time to touch grass

I just know some of these things from having to use Scala for some classes now wouldn't it be nice if they used Kotlin instead, or maybe if they were a bit more out of touch and used Java instead because at least that's a bit more relevant (edited)

Swift is an obvious one that's able to do that

think about all the cool stuff you could do

21:33

like building a crossbow with local parts

sub postfix:<:)>(Str $foo) or something

No phones, no cameras, no satellite

but what are we talking about

meloƞ

No phones, no cameras, no satellite

what if power in batteries would last

21:36

just no production etc

power plants all fail or electricity no longer exists

Maybe instead of operator overloading we just need vector types? That would cover the biggest use case

pilonpl

Vector types?

if it's power plant then plenty of big institutions have backup generators

meloƞ

Vector types?

vector2 vector3 vector4

pilonpl

vector2 vector3 vector4

Eh Vector vec3{{0, 0}, {0, 0}, {0, 0}}

21:39

What language doesn't provide that? :o

21:40

You just have a vector of type vector which expects a vector of any type

21:40

Vectorception

You can do that but the idea is to use operators to do stuff like adding vectors

21:42

So if it's a built-in type it could just work

21:43

Without overloading

We need Vector3<Vector3<float>>

Static cast the vector to an array

Actually would it be useful to have both position and velocity in one vector?

pilonpl

Actually would it be useful to have both position and velocity in one vector?

Depends - I don't recommend storing two important datasets in a single vector

21:45

But that's personal preference

21:45

Use hash map greenthing

greenthing

pilonpl

Actually would it be useful to have both position and velocity in one vector?

Just make a struct with two vectors, or more like have the two vectors in the one struct that you already have the rest of the stuff in

Yeah i know

actually it does matter for memory layout reasons, if you're doing 3D

Memory layout?

I think I would still separate them and control the workflow properly instead of smudging em together

pilonpl

Memory layout?

like, the way things are laid out in a struct

I never quite understood how that works

meloƞ

I think I would still separate them and control the workflow properly instead of smudging em together

also yeah, having a separate array of velocities and array of positions is often even better

I just hope the compiler does sensible stuff

Zigs compiler made me go crazy

pilonpl

I just hope the compiler does sensible stuff

In C the compiler doesn't do anything smart with structs

I often write boilerplate and just check for obvious errors by compiling it. Zig doesn't build with unused variables or unchanged variables that aren't marked const feelsbadman

It probably can reorder elements in a struct and it aligns them properly whatever the proper way is

Btw pilonpl when ddnet contribution for mighty dev role?

I don't know what do contribute lol

pilonpl

It probably can reorder elements in a struct and it aligns them properly whatever the proper way is

The standard says that it can not reorder elements in structs, and it is not allowed to pack them back to back

Add Haskell bindings

And it's complicated to understand how the code works at all

so you really should understand how your structs are laid out in memory if you care for performance

risu

I won't be reordering elements in a struct because i group them logically

I wonder what the reason might be for not allowing the compiler to reorder elements in a struct

pilonpl

calling convention stuff

21:59

You have a struct defined in a header file

Wow

21:59

Okay that might be a good reason

two .c files include that header file, but don't include each other

22:00

the struct needs to be compatible across those two compilation units even when they're compiled with two separate invocations of the compiler

Why do translation units even exist

22:01

Just compile everything as if it was one file

Or really do any optimizations

Yes

because C compilers are still not that fast we do really quite need incremental build support

No(t really)

LTO my beloved (makes some builds take like way longer)

No but fr, compiling c code with zig is actually pretty good

22:04

I had to when testing sdl3 - was fun

Why not just use C to compile C?

you still need a script to call the compiler to build your build script and then run it, but yeah, some projects do that

Just bootstrap the script once

22:06

still better than installing some makes and cmakes

pilonpl

Just bootstrap the script once

And ship one compiled for every OS and CPU architecture?

22:07

just so people can build your project

Well, we expect people to have a C compiler already installed

22:08

So they can compile the build script

I guess you can tell the user to manually compile your build script

Obviously, if you can tell them to install cmake

pilonpl

still better than installing some makes and cmakes

If your system doesn't have make idk what to tell you man

I do use make actually

22:09

It's kinda bad

22:09

But whatever

it's quite... GNU

22:10

GNU software tends to be annoyingly user-unfriendly and have a billion features that are just actively annoying if you aren't doing GNU-esque things

22:11

like how make is really tailored to compiling C

22:11

so the usage is just totally different for C and literally anything else

I am not sure if i use GNU software directly

22:12

I don't even know what software is GNU

You know you're in a bad place when a software wants you to use info instead of man

info?

22:13

I didn't know such thing existed

22:13

I usually do -h, --help or man

info is only used by certain things, it's not common

Btw using single dash for multi character flags is evil

pilonpl

Why not just use C to compile C?

That's done tho

22:14

C is written in C

pilonpl

I don't even know what software is GNU

GCC obviously, and the most commonly used C standard library implementation for example

I use clang

22:15

But i guess it's pretty much the same interface

22:15

Just different implementation

if you're on Linux you're still probably using glibc

Yes

pilonpl

But i guess it's pretty much the same interface

Hmm, gcc is much more polished

22:16

Clang is llvm bloat

22:16

But it's diagnostic's are great

Clang has better performance it seems

Yeah I hear clang compiles a bit faster but both produce comparable quality output

-Ofast goes brrrrrr

And what i mean by that is that i once tested it and it was better in that one specific situation lol

22:17

Very scientific

22:18

In don't know of llvm is bloated

Emacs and Nano are GNU software

22:19

as are the common implementations of most common tools

I use nano all the time

22:19

It works ok for basic stuff

22:20

I probably just use nvim

try pacman -Ql coreutils | grep bin for a list of examples of things that are gnu

I guess i can check on the website too

GIMP is a piece of GNU software that even normies have heard of!

22:22

(guess what the G stands for)

I am still waiting for the undestructive workflow

that too has very strong GNU vibes It has nice features but they're annoying to get to, and the defaults make no sense unless you're a nerd

22:23

and even then the defaults aren't actually good for things

That's why gimp should hire some people who know how to design a good user experience

GIMP is actually not bad at all for digital painting, but you wouldn't know that because support for pen pressure is not enabled by default

risu

GIMP is actually not bad at all for digital painting, but you wouldn't know that because support for pen pressure is not enabled by default

Krita exists, so Gimp has no reason to invest Also some things are very annoying to do

the matrix for tying different values to different inputs is really nice too, once you find it

What

22:28

And yeah i guess GNU programs are kinda bad

22:28

Chmod is in coreutils

like, you can make different brush attributes change based on things like pressure, velocity, direction, angle, and a couple others

And like why would anyone think it's a good idea to specify permissions using numbers?

pilonpl

And like why would anyone think it's a good idea to specify permissions using numbers?

you don't need to specify numbers, it's just really nice if your brain works in binary already

22:29

I think the numbers are nice

I mean yeah i usually to chmod u+x script.sh

Image attachment

22:30

this thing

22:31

and if you want more control you can edit each of those variables as a curve

I wonder what the [ program does, apparently it's also included in coreutils

I mean, it's not special, other editors have it too, but finding this menu is actual ass

risu

Click to see attachment 🖼️

I never knew what this thing was for

the tick in the top left corner means that the brush opacity is controlled by the pen pressure

22:33

top right means that the opacity also fades over time I'm guessing? Or does fade mean something else?

Over time?

22:33

How would that work

or over distance?

pilonpl

How would that work

well, while you're holding the pen down the image editor is real time, no?

22:34

then resets to 0 for the next stroke

I guess

another thing, the default dynamics are doodoo

22:35

yet after half a minute of tweaking this you can get a really nice feeling brush

Anyways it's almost midnight

22:37

And it's not saturday tomorrow

22:37

Unfortunately

22:37

I hope i can make some more progress on my 3D game tomorrow

pilonpl

Just compile everything as if it was one file

compilation creates one binary at the end, not 2. So for instance, you could end up with different struct layout for ddnet client and ddnet server which means connection would not work properly (or not at all)

Chairn

Well, due to endianness and the varying size of C types there's really no sense of network compatibility with C structs

23:40

they're only really guaranteed to be compatible on a single system
