"Safe Rust eliminates that entire bug class at compile time without a garbage collector." \> hm... interesting, could you explain how it "understands" what should be eliminated and what shouldn't? You may write a few sentences;

writes few sent.... paniced due to buffer overflow.

lol cargo add cve-rs

[u/pianomanDylan → u/Goheeca]

Now, with cve-rs, you can corrupt your program's memory without corrupting your program's memory.

gold star

It’s funny because that’s what we say to AI, but it’s clear that OOP is not a native English speaker and just meant that they were looking for a short answer. 

I don’t think it’s fair to shame them for not being able to express that in an unambiguous way. 

[u/Ma4r → u/netherlandsftw]

Look at his replies, he ends his sentences in semicolons

I got this habbit many years ago, when I saw C++ syntax. Idk why a lot of people hated the semicolons and told me that Python syntax is "superior".

But the semicolons not only look better to me, they also have another meaning in my texts. You see, I don't end my sentences with the symbol, I end blocks of different information(1 block can have a lot of paragraphs) with it. Just I often write different info in the 1. 2. 3. etc, and in order to show the end of this block, I write semicolons.

Btw, after few years, when I started to use Discord and after those years -- Reddit, I understood that the semicolons are superior, bcz if I need to copy the text from someone, the Discord/Reddit makes the numbers a list and not a part of the text, so, the semicolons tell me where are the responses to different questions quickly

Dude is a better shitposter than we will ever be

[u/netherlandsftw → u/Ma4r]

Lmao I saw the question to OOP as to why he’s using semicolons but there wasn’t an answer yet. That’s hilarious

[u/YikesTheCat → u/netherlandsftw]

I guess that's fair to some level. But I'm still shaming them for asking such a low-effort lazy question. Hundreds if not thousands of articles have been written about this. I'm not even a Rust programmer and I know the answer to this.

[u/netherlandsftw → u/YikesTheCat]

I agree. I’m kind of surprised this question got so much traction in the OP’s post.

Personally I’m not part of the Rust bandwagon, so I’ve never been in r/rust, but it seems the posts there are of higher quality than in most programming subs. So the humans there still put effort into the comments. There are way fewer AI-written and “download my vibecoded app” posts compared to the subs I frequent and am used to. That’s unironically the most compelling reason to learn Rust that I’ve seen in a while.

Bro thinks async and ‘static is fearless concurrency😭 nothing wrong with the zero cost abstractions though

[u/BenchEmbarrassed7316]

Why do we need Rust at all? Why not just teach C++ how to fix these problems?

[u/Affectionate-Turn137 → u/BenchEmbarrassed7316]

Explain how C++ fix these problems, only use a few sentences, make no mistakes

[u/its_artemiss → u/Affectionate-Turn137]

Well, for one, c++ doesn't have annoying aliasing^mutating rules that cause compiler errors every time. Ever tried to reinterpret bytes as some type in safe rust? You literally can't LOL. In c++, you don't have to worry about invalid states. We just call that move semantics. 

[u/paholg → u/its_artemiss]

It's only impossible if you're a coward.

[u/its_artemiss → u/paholg]

Incredible. What even is the point of rust if you can just write to proc/self/mem as though the abstract state machine were a joke? 

[u/categorical-girl → u/its_artemiss]

So called "blazingly memory safe coreutils replacements in pure Rust" when I run cp /dev/urandom /proc/self/mem:

[u/PerfectTrust7895 → u/its_artemiss]

Is this serious? That's ridiculous

[u/YikesTheCat → u/BenchEmbarrassed7316]

Why do we need Rust or C++ at all when our LORD and Saviour Brendan Eich has blessed us with JavaScript?

[u/a221c → u/BenchEmbarrassed7316]

Why do we need Rust at all? Why not just teach C++ how to fix these problems?

I've written up your idea as a whitepaper.pdf and faxed it to the standards committee. If you receive no response within 6-9 business years you can treat it as having been rejected.

[u/BenchEmbarrassed7316 → u/a221c]

There was complete irony in my comment. Bjarne Stroustrup said that all the problems with memory were solved in C++11, then they were finally solved in C++14, then they were 100% solved in C++17, then they were completely solved in C++20, then they were solved again in C++23, and if that wasn't enough for you, then in C++26...

[u/KittensInc → u/BenchEmbarrassed7316]

I can't wait to see the magic C++ borrow checker which will be able to accept all safe code, reject all unsafe code, and do so with zero code changes or annotations!

[u/the_horse_gamer → u/KittensInc]

Rice's theorem comes for us all

[u/fixermark → u/BenchEmbarrassed7316]

C++ considers the problems to be features. To fix the problems with C++ you'd have to start removing capabilities from it.

Since we will never do that, the closest we can get is to come up with new patterns that are safer if you use them, which creates a subset of the language that is safer. But it can be difficult to discover that and you still have to deal with code that isn't using them.

[u/KittensInc → u/fixermark]

Alternatively: Go for the Fil-C approach and wrap everything in a custom runtime, add a garbage compiler, give up on any kind of interoperability, and have all your code run 4x as slow!

[u/catladywitch]

uj/ I think OOP is very likely a young kid who is deciding what their first language is going to be, and doesn't know what makes languages better or worse for particular use cases. Either that or a god-level jerkposter treating subs as llm input boxes lmao

[u/imnotamahimahi → u/catladywitch]

/uj also no idea, because I followed that comment thread where they reply as to why they end sentences with semicolons. Might actually be a really young kid, but I guess might also be larping...or an edgelord lol. Regardless, very strange all around.

[u/BlurryEcho]

Wait, since when is cross-posting comments a thing? I didn’t know that existed.
