Goals and Priorities for C++

Re:Goals and Priorities for C++ by cmrdporcupine on Friday May 22, 2020 @08:08AM (#23271223)

The tooling is improving. It's so much better than it was. With CLion I have a modern refactoring IDE of excellent quality (just don't try to use it with large code bases like Chromium, though, ahem). Build systems have improved remarkably. We have two excellent open source compilers.

I actually enjoy working in modern C++ much more than I did in Java, which I did professionally for almost 10 years before this.

I like the idea of Rust, and followed it since the earliest days when Graydon proposed it. I like the syntax and the tooling. But every time I begin a project in it, the cognitive overhead of the memory safety features just throws me a loop. I have no doubt if I were to dig into a large and established code base using it it would click within a few days, but starting on my own... I lose focus quickly.

I do like Zig, though. It is a very nice C++ alternative.

What do you like about working in C++ more than Java?

Generally, I hear from people working in C++ that it's the only tool for their job, and only use it because no other tool measures up (in a despairing tone). If you don't mind my asking, what do you use it for?

I am not the person you're replying to, but in my experience / opinion if you want to do distributed high-performance numerical computing, executing on heterogeneous hardware, C++ is really far and away the best language to get this done. If you're CPU-only, maybe Fortran is a better option but when GPUs enter the mix I don't see how you're going to have an easier time getting the requisite performance with anything else.

I mean, like, you can interface with TensorFlow via Python but the big-kid parts of the implementation are in C++ / CUDA.

I feel great joy coding C++, more than any other language. C++ is built to be used. Every part of it was put in to solve real problems, and they do. I can write thousands of lines of code, and when it finally builds, the program works first time.

More systems level stuff than you'd ever use Java for. Google/Nest hardware devices (display assistant devices, other stuff).
