GUI
I'm new and I have only made console applications but I want to start developing gui since any product attracts people if it has a slick looking gui , but I don't know what you need to create a gui and searching it on youtube didn't help , I want to know what the common way of doing it is and it would be better if the gui application development works on linux (debian based distro)
thanks in advance

Does reinterpretcast require parentheses?
I left out parentheses on a reinterpret\cast, and it was accepted in unit tests but not in production. They use different compilers. I think the unit test should have failed. Am I right?uint16_t* pPointer = reinterpret_cast<uint16_t*>pSource
vsuint16_t* pPointer = reinterpret_cast<uint16_t*>(pSource)

How to "speed" up the read and writes
Hello, I'm really curious how exactly cpp is used in the field of finance. What methods and techniques are used when deploying servers on the stock market.
I may be completely wrong but I read that spaces are purchased to keep the servers as close to the exchanges as possible. That's how much speed matters.
Can someone give me resources that are used by seasoned programmers?

MPI or GPU: parallel computation of DEM code for particles
Recently I published a paper on a new contact detection algorithms for DEM (discrete element method) simulation of non-spherical particles.
Now I want the code to simulate 1 million + particles for industrial applications. As a beginner of HPC, which one is easier between CUDA and MPI, in terms of learning curve. I had some experience on OpenMP to make some computationally intensive loops run in parallel.

CTAD is incorrectly implemented by compilers
Hello,
I was browsing standard papers, as I always do before bedtime. While going through the paper [https://wg21.link/P2082R1](https://wg21.link/P2082R1), I noticed in section 3.1, which discusses "Fix deduction for aggregates with elements of array type," the following sample code:
template <typename T, std::size_t N>
struct A {
A array[N];
};
According to the cppreference site, it is supported by all three major compilers, but in reality, none of them can compile it. I am quite disheartened; none of the compilers are conforming to the C++20 standard. :(

why virtual function is wrong.
A long time ago, I tried to find an easy way to explain why C++ virtual functions are damaged. Finally, I found a good example to illustrate this.
Here's an example from C#. This is something C++ should support, but it can never achieve in c++.
public readonly struct Int32 : IComparable<int>, IConvertible, IEquatable<int>, IParsable<int>, ISpanParsable<int>, IUtf8SpanParsable<int>, System.Numerics.IAdditionOperators<int,int,int>, System.Numerics.IAdditiveIdentity<int,int>, System.Numerics.IBinaryInteger<int>, System.Numerics.IBinaryNumber<int>, System.Numerics.IBitwiseOperators<int,int,int>, System.Numerics.IComparisonOperators<int,int,bool>, System.Numerics.IDecrementOperators<int>, System.Numerics.IDivisionOperators<int,int,int>, System.Numerics.IEqualityOperators<int,int,bool>, System.Numerics.IIncrementOperators<int>, System.Numerics.IMinMaxValue<int>, System.Numerics.IModulusOperators<int,int,int>, System.Numerics.IMultiplicativeIdentity<int,int>, System.Numerics.IMultiplyOperators<int,int,int>, System.Numerics.INumber<int>, System.Numerics.INumberBase<int>, System.Numerics.IShiftOperators<int,int,int>, System.Numerics.ISignedNumber<int>, System.Numerics.ISubtractionOperators<int,int,int>, System.Numerics.IUnaryNegationOperators<int,int>, System.Numerics.IUnaryPlusOperators<int,int>

What would you want to have in an UI library?
I'm creating a UI library in C++, using sdl2, generally for study. But the question is: among the alternatives that already exist, what is missing? What you would like to exist that does not exist.
As the project is still in its infancy, I don't even have a public repository on GitHub, but as soon as I have I'll publish it here. Since I'm doing it in C++, I intend to have binds for the newer versions of python (>3.10) using pybinds11.
I'm still planning the features, so far the main ones (besides the basics of a UI library) will be:
- Use of XML to compose UI (similar to the .net MAUI xaml system;
- Event handling system by widget;
- Static and dynamic windows (which update in the main loop);
- Routing between pages
The Windows version will be compiled in GCC using msys2 and the Linux version will also be compiled in GCC, using wsl2. There won't be for Mac because I don't have Mac lol
Note: I'm working on this project alone.

gcc development
tldr; ranting about old-school gcc development techniques.
Recently I started looking into contributing to libstdc++. I am just mesmerized that this huge project still uses development techniques from some decades ago: mailing lists, configure+make, no chat forum. I have never interacted myself with mailing lists and it just feels so archaic. Can you even easily search through them? People actually copy-and-paste git patches into mails? Editing of sent messages seems impossible?
Currently I am only interested in contributing to libstdc++. I tried building it yesterday night and it feels like I need to build the whole compiler beforehand?
Is there a reason to use make over CMake? Is someone working on a switch to CMake or is it just too much work?
Are there any plans to move to a modern and unified collaboration platform, e.g. github, self-hosted gitlab?
All in all the development process feels a bit outdated and I could imagine that it puts off alot of new contributors.
(Documentation on the other hand is quite thorough, but still not visible appealing to younger generations.)

Looking for a C++ Tutorial that helps me with good programming practices in modern C++
Hi
I have been doing programming for some time now, and my code in C++ has been limited to only Leetcode and Codeforces etc. I finally learnt OOPs and other C++ concepts like const-ness and overloading, and would like to build something.
Can the community suggest a tutorial (could be a blog or YT video) that builds up a fairly large C++ project from scratch and specifically focuses on good programming practices while using modern C++ (preferably C++20)? It can be as complex as you like.

Alternatives to djarek/certify?
It appears that Damian Jarek's certify lib has been archived without comment as of March 2024, so I'm wondering if there are other libraries folks are using for similar purposes. I'm trying to implement a relatively simple HTTPS client using Boost.Beast on Windows, but I'd like to try to keep the code at least open to becoming portable in future.
If anyone's got a suggestion for an alternative certificate handling library, I'd love to hear about it.

Looking for examples of good idiomatic code/libs to read for catching up with "modern" C++
I've used C++ a lot in the past but had a pretty long hiatus, I lately have the feeling that I want to get back to more "formal" practice after years of backend dev and started to learn a lot of concepts that were added to what folks commonly refer as "modern C++" (value/move semantics, type erasure, compile time/constexpr and the like) and I'm at the point I would benefit from reading avidly some actual code to get a feel for how all those concepts play out in concrete applications.
Would you please suggest some nice codebase to dive into ?
I'm looking for medium sized libs/projects that you could consider representative of modern C++ regardless of their purpose (I'm still in a quite general approach) please be kind enough to add a quick comment on what you find interesting.

Laptop reccomendation for serius C++ development
I'm considering buying the latest MacBook, or possibly waiting for the M4 model, but I've heard many negative experiences regarding development on Macs. It seems that those who find Macs suitable for software development are often web or Android developers, which is quite different from what C++ programmers typically work on.
