It's amazing what modern game engine's can render. That looks almost real, kudos to the creators

It’s fine but have you seen starfield?

C++ is fiiiiine. Just use the modern variant of the language, don't bother with hand-optimizing your memory allocators, and generally avoid anything involving pointer arithmetics. So, basically, use it like you would use Python.

That's a great way to get performance as shitty as python's.

[-] zik@lemmy.world 42 points 1 month ago

C++ can do a lot of things but one thing it can't do is perform as poorly as python.

Not quite, but smart pointers in the wrong location can be quite wasteful in terms of CPU cycles.

This is a very "yes but still no" thing in my experience. Typically, I find that if I write "naive" C++ code, where I make no effort to optimise anything, I'll outperform python code that I've spent time optimising by a factor of 10-30 (given that the code is reasonably complex, this obviously isn't true for a simple matrix-multiplication where you can use numpy). If I spend some time on optimisation, I'll typically be outperforming python by a factor of 50+.

In the end, I've found it's mostly about what kind of data structures you're working with, and how you're passing them around. If you're primarily working with arrays of some sort and doing simple math with them, using some numpy and scipy magic can get you speeds that will beat naive C++ code. On the other hand, when you have custom data structures that you want to avoid unnecessarily copying, just rewriting the exact same code in C++ and passing things by reference can give you massive speedups.

When I choose C++ over python, it's not only because of speed. It's also because I want a more explicitly typed language (which is easier to maintain), overloaded functions, and to actually know the memory layout of what I'm working with to some degree.

I guess I should have clarified in my original comment that I was exaggerating - obviously, C++ doesn't get as bad as python, not even into the same ballpark.

My emphasis was on "don't use C++ like you would python" because that's not good advice imo.

I love C++ I love C++ I love C++ I love C++

Honestly that's most things in life.

The more complex your project, the more likely you are to run into the rough patches or quirks of whatever it is you're working with.

I also enjoyed this album by Incubus.

What programming language is Afungus Amongus?

[-] Seraph@fedia.io 18 points 1 month ago

It's so we can recreate that, but with like laser beams and stuff.

[-] electricprism@lemmy.ml 7 points 1 month ago

When you first saw C++ were you blinded by its majesty?

[-] nickwitha_k@lemmy.sdf.org 2 points 1 month ago

(with lasers): "How about now?"

[-] jeff@programming.dev 17 points 1 month ago

My favorite project was C++; it was big, it was complicated, there was a massive team working on it, I got to work with high level abstractions while occasionally dealing with really low level concerns.

It was really hard, but now writing code in every other language I've worked in has been really easy.

[-] merthyr1831@lemmy.ml 16 points 1 month ago

I feel the same every time I see JavaScript. C++ is one of those ugly but also elegant languages you should try at least once.

[-] CanadaPlus@lemmy.sdf.org 8 points 1 month ago* (last edited 1 month ago)

You know, in that case, the blame doesn't fall on the guy that made it. Shit on the people that made the development deadline a couple weeks, and then decided to keep the product in place for decades.

[-] Psythik@lemmy.world 13 points 1 month ago

The people who invented C++ never went outside, otherwise they would have never invented C++.

What if we didn't want more sea, just spikier? C#

I look out acroth the thea, and thee what I can thee. I can't pronounth that thtupid language; I'll write in lithp.

Ocean + traversing a desert => Ocaml?

I improved the C! It is greater! More potent! But what is this? I look at at my poor boat, upon which I traverse the waves of the C++ 7; now it is degraded. Now its beautiful metal hull has oxidised. Oh, the dangers of the C. ...Wait, that gives me an idea...

[-] CodexArcanum@lemmy.world 7 points 1 month ago

That's why Rust had to be developed! Oxidize all those computers and stuff back to nature.

[-] CodexArcanum@lemmy.world 5 points 1 month ago

What's with the downvotes on a silly joke? Is the Linux kernel team on Lemmy?

[-] affiliate@lemmy.world 7 points 1 month ago

and then they had the audacity to put that picture on the cover of the textbooks

[-] Fixbeat@lemmy.ml 6 points 1 month ago

Yes, a perfect thing of beauty.

[-] HStone32@lemmy.world 5 points 1 month ago

its even worse that they hat to ruin a beautiful existing language to do it.

The issue is not aesthetic. It is that the feel doesnt match up to the look

What's wrong with embedded C? Would you rather write assembly?

[-] AnnaFrankfurter@lemmy.ml 1 points 1 month ago* (last edited 1 month ago)

Hey assembly is good in the sense you are only dealing with one language but in embedded C you get bad parts of both C and assembly. You have to follow weird C99 or even C89 syntax and on top of that for each micro controllers you have to sift through several hundred pages of data sheet. Each one needing separate registers to be setup in a particular way for every single operation and so much more stupid ass shit.

[-] leo85811nardo@lemmy.world 2 points 1 month ago* (last edited 1 month ago)

All of the quirks you said are true, yet they still established the "okay" ecosystem of hobby-grade microcontrollers like Arduino, IoT devices, and other small scale robotics systems. None of them would have happened without the "okay" abstraction C/C++ provides as opposed to assembler
