Google recently rewrote the firmware for protected virtual machines in its Android Virtualization Framework using the Rust programming language and wants you to do the same, assuming you deal with firmware.

In a write-up on Thursday, Android engineers Ivan Lozano and Dominik Maier dig into the technical details of replacing legacy C and C++ code with Rust.

"You'll see how easy it is to boost security with drop-in Rust replacements, and we'll even demonstrate how the Rust toolchain can handle specialized bare-metal targets," said Lozano and Maier.

Easy is not a term commonly heard with regard to a programming language known for its steep learning curve.

Nor is it easy to get C and C++ developers to see the world with Rust-tinted lenses. Just last week, one of the maintainers of the Rust for Linux project - created to work Rust code into the C-based Linux kernel - stepped down, citing resistance from Linux kernel developers.

"Here's the thing, you're not going to force all of us to learn Rust," said a Linux kernel contributor during a lively discussion earlier this year at a conference.

Here's the thing, you're not going to force all of us to learn Rust

That seems like a poor attitude imo.

[-] lowleveldata@programming.dev 35 points 3 months ago

A valid point tho. Generally it is difficult to ask everybody to learn a new language.

[-] tiredofsametab@fedia.io 49 points 3 months ago

I mean, I work as a software engineering and if I'm not doing continuing ed, be it about architecture, storage, or new languages, I'm going to be of less value in the marketplace. I've learnt languages I didn't particularly want to in the past for work (though I generally came to tolerate or even like some of them. Not lua, though; lua can go to hell).

If Rust truly is the better, safer option, then these people are holding everything back.

"learn Rust" in this case is learn it to a level where all of the little behaviour around cross language integrations are understood and security flaws won't be introduced. Expert level.

It's not "I did a pet project over the weekend".

[-] tiredofsametab@fedia.io 25 points 3 months ago

You are correct and I am aware of that. However, it also seems that they both refuse to learn it and refuse to work with people at that expert level based on the recent drama, which seems very much like holding things back to me.

C/C++ is the bedrock of our modern civilization in some ways more fundamental than actual bedrock, the first step in getting any OS running is making it run C and after that you are basically done, it’s not surprising that developers resist, if nothing else it’s a common language, and standards are hard to change on the best of days. This isn’t just learning a language, it’s a complete paradigm shift.

[-] calcopiritus@lemmy.world 15 points 3 months ago

The bedrock of modern civilizations is expensive to develop, buggy and unergonomic though.

If you make C run, you probably (I'm not sure, would have to verify) can make rust run. And if there isn't yet, there will probably soon be a C compiler written in rust, so you can choose to bootstrap from wherever you prefer.

C's ABI will probably last longer than C, since there is not a stable rust ABI though.

[-] BatmanAoD@programming.dev 7 points 3 months ago* (last edited 3 months ago)

You cannot, today, build a Rust compiler directly from C, but you're right that people are working on it. See this recent post: https://notgull.net/announcing-dozer/

Edit: you can certainly bootstrap Rust from C via C++, as the article covers. I misinterpreted the comment above.

It's not a question of what's the better option. In reality we have a lot of software that already exists and works, and you can't replace it all in bulk at the same time. So the question is whether the implementation of Rust makes logistical sense, given the difficulties of maintaining currently existing software while replacing some parts of it.

[-] theherk@lemmy.world 37 points 3 months ago

Fortunately, they aren’t being asked to do that. All the rust team was requesting was metadata about the call signatures so that they could have a grasp on expected behavior.

[-] BatmanAoD@programming.dev 24 points 3 months ago

It would be a valid point if he weren't literally speaking over the people trying to tell him that they're not demanding he learn Rust: https://youtu.be/WiPp9YEBV0Q?si=b3OB4Y9LU-ffJA4c&t=1548

Oh jeeze, you have no idea. You can watch it yourself: https://youtu.be/WiPp9YEBV0Q?si=b3OB4Y9LU-ffJA4c&t=1548

That timestamp is about where the audience member (a maintainer of ext4 and related utilities) starts speaking. The "here's the thing" quote is around 28:40.

[-] GetOffMyLan@programming.dev 21 points 3 months ago

Wow what an absolute dick

[-] PlexSheep@infosec.pub 6 points 3 months ago

I mean aren't they forcing everyone else to learn C/C++ otherwise? If we follow that logic, at least

[-] GetOffMyLan@programming.dev 4 points 3 months ago

I guess you can argue it's already written in C. So that was always a requirement.

[-] sukhmel@programming.dev 3 points 3 months ago

That way we'll just find maintainers went near extinct over time, just like COBOL developers that are as rare as they are expensive. Only Linux kernel isn't a bank, and maybe will not have as much money to pay to rare developers capable of maintaining C codebase

One of the deep-pocketed founding members of the Rust Foundation says it's easy. I'm surprised.

[-] Ephera@lemmy.ml 21 points 3 months ago

Wut? They're a member, because they find Rust useful. This is just them saying another time that they find Rust useful.
While they (and everyone using Rust) will benefit off of more people using Rust, it's not like they have a vested interest to the point of spreading misinformation.

[-] lysdexic@programming.dev 11 points 3 months ago

They’re a member, because they find Rust useful. This is just them saying another time that they find Rust useful.

Fans of a programming language stating they like the programming language is hardly thought-provoking stuff. There are also apps written in brainfuck and that means nothing as well.

[-] Ephera@lemmy.ml 5 points 3 months ago

I'm pretty sure that's not how dyslexia works, but either way, I didn't write that. And while the title of the article suggests otherwise, the news here isn't that Google says something is easy. The news is that they published a guide to make that thing easy.

[-] lolcatnip@reddthat.com 15 points 3 months ago

Clearly Rust is a conspiracy.

[-] lysdexic@programming.dev 6 points 3 months ago

Clearly Rust is a conspiracy.

Anyone in software development who was not born yesterday is already well aware of the whole FOMO cycle:

  1. hey there's a shiny new tool,
  2. it's so fantastic only morons don't use it,
  3. oh god what a huge mistake I did,
  4. hey, there's a shiny new tool,
[-] Spore@lemmy.ml 10 points 3 months ago

I assume that you do know that tools improve objectively in the cycle and are making a joke on purpose.

They need to tell that to Theodore Ts’o.

[-] eronth@lemmy.world 7 points 3 months ago

Rust is one of those things that every time I look into it, I don't really follow what makes it so good. What's a good starter project to learn the language and get a sense of what makes it worthwhile over the established stuff?

If the target for the firmware has stdlib already implemented, my experience has been that it is indeed easy with minimal experience in the language.

[-] 0x0@programming.dev 32 points 3 months ago

Mixing "firmware" with "easy with minimal experience" in the same sentence makes me cringe...

[-] nickwitha_k@lemmy.sdf.org 13 points 3 months ago

That's fair. To be clear, I meant minimal experience with the Rust programming language. I've mainly tinkered with ESP32 types of MCUs in Arduino and CircuitPython when it comes to firmware, but have much more software experience. In some ways, I found the little bit of Rust that I tried easier because of the tooling - defaulting to a CLI tool to flash rather than an IDE is much more comfortable for me.

Meh, it's depends on what you do. I know several low level C engineers who would be far more comfortable rolling a fresh driver over doing some more abstract intro CS projects.
