Imagine if there was a hack so bad that it caused everyone to become unable to develop in C and C++.

Classic "let's just make the cure worse than the disease" mindset among security enthusiasts.

Well, there is one that will imply you can only develop using anything that you have bootstrapped yourself, using hardware that you have designed and manufactured yourself, using tools that you have designed and manufactured yourself, using tools that you have designed and manufactured yourself ...

... with your own bare hands.

Why the swipe at Linus? He's been supportive of rust in the Linux kernel.

[–] nutsack@lemmy.world 10 points 3 days ago* (last edited 3 days ago) (1 children)

they don't swipe him at all. I don't know why his picture is there

If only it were that easy to snap your fingers and magically transform your code base from C to Rust. Spoiler alert: It's not.

How utterly disingenuous. That's not what the CISA recommendation says, at all.

[–] Solemarc@lemmy.world 85 points 4 days ago

I don't get why we're taking a swing at Linus here. The article only mentions him in relation to the rust for Linux project being slow going. But, it IS going and the US government has only stated that "you need a plan to move to a memory safe language by 2025 or you might be liable if something bad happens as a result of the classics (use after free/double free/buffer overflow/etc.)" but I don't think Linux would count it's free software and it does have a plan.

But there is context to it:

The report on Product Security Bad Practices warns software manufacturers about developing "new product lines for use in **service of critical infrastructure or [national critical functions] **NCFs in a memory-unsafe language (eg, C or C++) where there are readily available alternative memory-safe languages that could be used is dangerous and significantly elevates risk to national security, national economic security, and national public health and safety."

It's for new products that are very important to critical infrastructure and need to be safe as possible. The article writer seem not to be aware of this context:

Take Rust in Linux, for example. Even with support from Linux's creator, Linus Torvalds, Rust is moving into Linux at a snail's pace.

Because Linux is the biggest software in the entire world and they do lot of stuff their own way. Rust is integrated slowly for future new projects. It makes sense to move in snail pace. The government doesn't suggest the Linux project to stop using C entirely. The government "recommends" to start new projects in memory safe languages, if it is a critical software. That makes sense to me.

You see, people who've spent years and sometimes decades mastering C don't want to master the very different Rust. They don't see the point.

No, totally wrong. C programmers in Linux do not NEED to learn or master Rust. They just need to cooperate. The problem is, that some C programmers refuse to cooperate with Rust. They just want Rust to disappear. That has nothing to do with mastering the language. They refuse to make changes to their C code, so it can cooperate with Rust code via bindings.

After all, they can write memory-safe code in C, so why can't you?

Nonsense argument, and false too. If that was the case, why do we have memory safe languages? Clearly people make mistake, old and new. Besides Linux is not the only software in the world.

Converting existing large codebases to memory-safe languages can be an enormous undertaking.

Nobody says old code should be rewritten in Rust. Neither the government, nor the Rust programmers in Linux suggest that. It's not about rewriting code in memory-safe languages, its about new projects.

Either this article is a misrepresentation or misunderstanding. Or I misunderstand the article or government. I don't know anymore...

Doubly so... Don't care what the language is, or what the advantages are... Even if there's a considerable security advantage to a new language... There's no such thing as a language that's advantages outweigh the security risks of rushed development to convert decades of tested code.

I would argue that's not the biggest problem, the biggest problem is that for you to refactor a function to work with rust, you need to refactor all the subsystems that rely on that function, and that take time, and you need to explain for the C dev why it need to be done, try to explain that for the amount of C devs in the kernel

I don't even think the rust devs where asking for that. They are refusing changes by rust devs that help with rust while making the c code clearer and even refuse to answer questions about the semantics behind the c code. At least as far as I can see from the outside.

The US government has more pressing issues I think.

Maybe it can shut the fuck up an let me do my job in contrast to its judicial branch.

My friend from university sends me his Rust code snippets sometimes. Ngl it looks like a pretty cool language.

There was also that tldr reimplemention in Rust that is a gatrillion times faster than the original.

I really want to give it a try but I have executive dysfunction and don't have any ideas of what I could use it for.

[–] ScreaminOctopus@sh.itjust.works 23 points 4 days ago (8 children)

The main issue I have with rust is the lack of a rust abi for shared libraries, which makes big dependencies shitty to work with. Another is a lot of the big, nearly ubiquitous libraries don't have great documentation, what's getting put up on crates.io is insufficient to quickly get an understanding of the library. It'd also be nice if the error messages coming out of rust analyzer were as verbose as what the compiler will give you. Other than that it's a really interesting language with a lot of great ideas. The iterator paradigm is really convenient, and the way enums work leads to really expressive code.

[–] asdfasdfasdf@lemmy.world 5 points 4 days ago* (last edited 4 days ago) (3 children)

Why not just use the C ABI?

And what libraries are you referring to? Almost all the ones I've used have fantastic docs.

Of course its rewrite is nearly infinitely faster than the original JavaScript.

[–] tourist@lemmy.world 4 points 2 days ago (1 children)

oh

lol

didn't cross my mind that someone would make a CLI program in js

I mean, I've done it, but I am a registered dunce cap owner.

[–] SpaceNoodle@lemmy.world 2 points 2 days ago

Well, so is that guy.
