Modern C++ Programming: Busato
github.comthere are so many job listings for c++ in big tech, but it feels like it's hard to gain proper c++ experience without already being on those projects. it's sweet that those c++ systems are probably critical and actually do cool things, but if I wanted to be a c++ guy there, it's hard to get the experience without already being there I feel. c++ actually doesn't look too bad with RAII?
but maybe it's a dying breed anyway, so I should just learn rust/go/zig/etc
This will probably run foul of some purists but Unreal Engine is a large C++ project with a vast amount of documentation, community, examples, and serves a lot of use cases.
It's not standard C++ but also it illustrates why lots of projects go that route.
Because it's niche, it might not be resume fodder but it will scratch the itch if you just want to play with C++.
C++ is still the de facto standard language for new high-performance, high-scale software. It isn’t going anywhere.
Learning Rust is probably onone of the more accessible ways to get this kind of experience. It won't teach you everything you'd need to know to write C++ professionally, but it teaches a lot of the it, including a lot of best practices that it's otherwise hard to learn outside of a professional environment.
I don't know, someone who solves their borrow checker errors by adding more dynamic allocations (which seems to be common/recommended), will be taught how to program in Java, not C++.
It's a dying breed in that it's being outgrown by others and the niches where it's the best choice are getting fewer, but it's not going away soon either.
For example high performance multithreaded code is now largely written in languages that are better for concurrency correctness, because the added development speed translates to added runtime performance by letting you iterate more in the same timeframe/budget.
A good understanding of the how the C/C++ memory safety bugs happen and lead to vulnerabilities is important to learn if getting into it.
C++ rules in the gaming industry, HFT, HPC, language runtimes.
Speaking of which what do you think all the languages that build on top of GCC and LLVM, depend on?
To me, using a programming language that lets me manage memory on a problem where it was important to me (because constraints or performance or whatever) has always been eye opening. go feels like a different thing there, but I suppose cgo can get you into the realm.
Cgo has its own performance overhead problems, though.
CUDA is an extension of C++ just like C++ is an extension of C. Deployed CUDA is growing exponentially. C++ is definitely not a dying language!
Nit pick: there are CUDA extensions for multiple programming languages, e.g. Fortran, but indeed the CUDA extension for C++ is the most widely used.
This is similar how there are OpenMP extensions for multiple languages, but the one for C/C++ is the most widely used.
Ha, why another programming language? I thought we wouldn't need to learn these in the AI era.
C++ is a rather old programming language.
"This open-access course is directed at those who are already familiar with C and object-oriented programming" ... but not C++
That's a very, very small target you're aiming at there.
Regardless, it is a very comprehensive review for C++ programmers, and even intermediate ones will probably see new material there.
"This open-access course is directed at those who are already familiar with very old C++ and object-oriented programming" ... but not modern C++
Written this way, the target is bit larger.
Another book tactically missing memory and ownership design for modern c++ apps. I think there is no more important topic for teaching. There are some slides in advanced sections but it's quite ironic one needs to know about it from the start!! Who owns memory? How to pass it? Move? Borrow? How to communicate it for readers? It's like a tribal knowledge.
Every time I touch enterprise C++ codebase it's a freakshow heavily struggling with memory management.
As reference the material could be good, as study it's very questionable.
Do you have any recommendations for books/materials that do include these topics? I've never used c++ professionally, but have been starting to learn it and would appreciate a modern reference on these items.
Nothing did more damage to c++ code bases than people not understanding this. People hear "smart pointers are good" and use them for everything. Not understanding that it's just the lesser evil and still extremely rarely needed (vs just stack memory or variants)
