    I just read through a few chapters. This is actually a very nice and solid resource!

      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.

        • on_the_train a day ago

          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)

          there 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

          • jayd16 a day ago

            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++.

            • jandrewrogers a day ago

              C++ is still the de facto standard language for new high-performance, high-scale software. It isn’t going anywhere.

              • nicoburns a day ago

                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++.

                  • nicoburns 11 hours ago

                    That's only recommended for beginners while they get tuo to speed (to try and help them avoid ahve to learn too much at once). It's absolutely not recommended in general. The whole point of the borrow checker is to enable memory safety without heap allocating and garbage collecting everything.

                • fulafel 21 hours ago

                  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.

                    What are these languages? I'm curious because C++ is the standard in my community so it's all I ever hear about (and Rust from the adventurous few).

                    • fulafel 14 hours ago

                      Java, Rust, Go, C#, Swift are the biggest ones (in no particular order) on the CPU side.

                      On the GPU side I'm not as up to date, but there's a lot of Python-ish stacks like JAX, PyTorch, Mojo, etc.

                      • qwertyuiop_ 13 hours ago

                        GPUs don’t run python.

                    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?

                    • portender a day ago

                      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.

                      • stingraycharles a day ago

                        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!

                        • adrian_b 19 hours ago

                          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.

                        "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.

                        • grg0 a day ago

                          Regardless, it is a very comprehensive review for C++ programmers, and even intermediate ones will probably see new material there.

                          • actionfromafar a day ago

                            "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.

                            I think you have to be more specific than "modern". "Modern C++" used to mean smart pointers etc. I assume this isn't that.

                              Ha, why another programming language? I thought we wouldn't need to learn these in the AI era.

                              • MathMonkeyMan 18 hours ago

                                C++ is a rather old programming language.
