@NeXus didn't you know? Quantum computers have firmware written in html and php!

Ofc, what else would you use?

C++20 concepts and abbreviated templates are just what I was looking for

10:14

I wonder how they even made it so far without this, it's a fairly obvious thing to add

10:16

void quick_sort(RandomAccessIterator auto begin, RandomAccessIterator auto end)

10:18

Very clean error messages, very easy to understand, no need for the iterator_traits tags hacked with doubling up templates

10:19

or god forbid if constexpr(std::is_same_v...

Great talk, exactly how I approach most any alien codebase I approach nowadays

ow to write

in javascript

just js things

rust macros are a world of its own

18:13

thats awesome

c++ preprocessor looks like a 5y old kid against this

18:14

https://github.com/dtolnay/proc-macro-workshop

c++ has static analyzers like clang-tidy for stuff like that. it's also easy to write your own clang-tidy checks

18:18

and i think clang-format even keeps headers sorted

yeah, but you need clang-tidy

18:19

and its not just this you can do

also, about powerful macros in general: it has to be used carefully, otherwise it's hard to find out what your program will look like

18:20

and these kinds of macros can increase compile-time a lot

still, they are good

18:22

@deen do you know rust btw?

All abstractions have cost, some at compile time, some at runtime, some in human time. C++ completely ignored the compile time until C++20 where modules are coming to rescue us from the dreaded 15 minute compile of a single TU

18:37

It's usually the human time cost that people forget. Coming up with these fancy abstractions takes valuable time and fully realizing it's consequences also takes the reviewers time. So you need to be careful when abstracting something away

18:40

Rust macros are indeed some of the most powerful I've tried, nim also has great macros

well rust is still being actively developed, gcc took years to get where it is with compile times

18:44

and i think the stable beta and nightly system is rly good https://doc.rust-lang.org/book/appendix-07-nightly-rust.html along with the "editions"

Has anyone seen the UE5 tech demo btw?

PS5 Unreal Engine 5 Tech Demo

18:56

I don't think anything will come close to unreal for real time realistic rendering for a long time

im already amazed by how good FF7 remake looked on the old 2016 ps4

18:59

it uses ue4

I didn't think global dynamic illumination would be possible for quite a while

19:02

or cinematic quality assets being ingame, nanite seems to do billions of tris with ease (I'm guessing some dynamic generation of optimized meshes is going on here)

19:03

(e.g. if you are too far, some of the tris would contribute less then a pixels, thus can get optimized out, neighbouring tris with very similar normal vectors wouldn't affect lighting that much so can be optimized out)

"Through a triangular perspective, we have increased the number of triangles triangularly. In other words, there a billions of billions of triangles in this triangular space.” -Neil Degrase Tyson

19:04

funny comment

19:04

gta 6 with this graphics

I wonder if they'll open source ue5 too, ue4s source has been very informative to me

@Learath2 what do you get out of these huge codebases?

Well whenever I do a feature for any project, I like to first think about whether I've seen it somewhere else

20:08

These huge codebases are usually a goldmine for stuff like that

20:09

It never made it's way into ddnet but I took a look at ue4's editor and how it handled editing multiple objects together, e.g. intersecting a list of props

20:12

We really should get something like clang-format for teeworlds

20:13

Does anyone remember what we were missing in clang-format to get it to do teeworlds format?

https://github.com/ddnet/ddnet/pull/1580

Add .clang-format by edg-l · Pull Request #1580 · ddnet/ddnet

We should discuss if these rules are good. The ones i added i think are the best and match the current style. (allman) I didn't add any script, but it would be cool if bors can format after...

20:14

" guess this will make cherry-picking from teeworlds and to ddnet7 harder, so let's not add a .clang-format file for now."

Hm, that's right, maybe we should start checking the incoming pull requests atleast

idk if we have the tools to do that

Github actions can handle it

not sure
