From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is a little off topic and admittedly an oversimplification, but people saying Rust's memory safety isn't a big deal remind me of people saying static typing isn't a big deal.
Someone linked the thread from Phoronix forum and the comments are so awful. Imagine having to deal with people like this.
One of them reads:
We need Microsoft people like we need fleas. Why can't they work for projects we don't like, like GNOME?
It is funny because Ts'o works at Google, lol.
Phoronix comments are a special place on the internet. Don't go there for a good discussion.
Ted Ts'o is a prick with a god complex. I understand his experience is hard to match, we all have something in our lives we're that good at, but that does not need to lead to acting like a fucking religious fanatic.
I understand his experience is hard to match, we all have something in our lives we're that good at
At some point, that mix of experience and ego becomes a significant liability. He's directly hurting the adoption of Rust in the kernel, while the C code he's responsible for is full of problems that would have been impossible if written in safe Rust.

crash from undocumented function parameter invariants
My favourite, as that was the exact point the dev was making in his talk, that the stuff is badly documented and that the function signature would document it perfectly.
Dude, three CVEs were enough. Stop kicking the blood puddle.
Agreed. His experience might be useful if he were there to engage, but he’s clearly not. It seems like he just wanted to shout down the project and it seems like he was somewhat successful.
No intention of validating that behavior, it's uncalled for and childish, but I think there is another bit of "nontechnical nonsense" on the opposite side of this silly religious war: the RIIR crowd. Longstanding C projects (sometimes even projects written in dynamic languages...?) get people that know very little about the project, or at least have never contributed, asking for it to be rewritten or refactored in Rust, and that's likely just as tiring as the defensive C people when you want to include Rust in the kernel.
People need to chill out on both sides of this weird religious war. A programming language is just a tool: its merits in a given situation should be discussed logically.
I imagine this mentality is frustrating because of how many times they have to explain that they weren't forcing people to learn Rust and that the Rust bindings were second class citizens. They never said to rewrite the kernel in Rust.
Who is Ted Ts' in this context?
He's the guy you hear vexing rust in the video posted. While both languages have their pros and cons, he chooses to just blast this other guy by repeating the same crap over and over without letting him reply. Basically the kind of person with a "I win because I'm louder" demeanor.
The comments from that article are some of the most vitriolic I've ever seen on a technical issue. Goes to prove the maintainer's point though.
Some are good for a laugh though, like assertions that Rust in the kernel is a Microsoft sabotage op or LLVM is for grifters and thieves.
Who the fuck is this little shit? Can't they even be a little considerate towards rust? Just because they have 15 years worth of inertia for C doesn't mean they can close their eyes and say "nope, I'm not interested". I do not see how the kernel can survive without making rust a first class citizen
It’s Ted Ts’o, the maintainer of the ext4 filesystem amongst other things.
little shit
Though you’re still accurate despite his seniority.
There's really only one valid response to Ted Ts'o:
If you think you can do better with C, prove it.

You seem really invested in pointing out those shortcomings. I respect that.
Arrogant hypocrites are a pet peeve of mine. If someone is going to act like progressive technology changes are beneath them and unnecessary, they should be able to put their money where their mouth is.
Oof, that video... I don't have enough patience to put up with that sort of thing either. I wonder how plausible a complete Rust fork of the kernel would be.
That person in the audience was really grinding my gears. Just let the folks you're talking to answer you; no need to keep going on your diatribe when it's based on a false assumption and waste the whole room's time.
let's not lose focus of what's important here, and that is a room full of people hearing my voice and paying attention to me for as long as I manage to hold it
It's always been this way. Except that it was kernel developers arguing with kernel developers over C code. Now it's relative newcomers arguing with kernel developers over Rust code that the kernel devs don't necessarily care about. Of course it's going to be a mess.
A fork is of course possible, but operating systems are huge and very complex, you really don't want to alienate these folks that have been doing exclusively this for 30 years. It would be hard to keep the OS commercially viable with a smaller group and having to do both the day to day maintenance, plus the rewrite. It's already difficult as it is currently.
Rust will be a huge success in time, long after the current names have lost their impetus. This is not a "grind for 4 years and it's done" project.
NOT a fork of Linux, but Redox is aiming for a Unix-like OS based on Rust – but even with “source compatibility” with Linux/BSD and drivers being in userspace, my guess would be hardware drivers are still going to be a big speed bump
All you need nowadays for a decent Unix-like is compatibility with a handful of Linux softwares and a web browser. Hell, if you could get WINE working on your kernel you could maybe support as many Windows apps/games as Linux for free.
The big issue, as I see it, is performant drivers for a wide range of hardware. That doesn't come easy, but I wonder if that can be addressed in a way I'm too inexperienced to know.
But projects like Redox are a genuine threat to the hegemony of Linux - if memory safety isn't given the true recognition it deserves, projects like Redox serve to be the same disrupting force as Linux once was for UNIX.
Just fork and port Ext4 to Rust and let the little shit sit in his leaking kiddy pool out back.
I admit I'm biased towards C-languages out of sheer personal preference and limited exposure to Rust but I am wondering, are there any major technical barriers to Rust replacing these languages in it's current form anymore?
I know there has been a lot of movement towards supporting Rust in the last 6 years since I've become aware of it, but I also get flashbacks from the the early 00's when I would hear about how Java was destined to replace C++, and the early 2010's when Python was destined to replace everything only to realize that the hype fundamentally misunderstood the use case limitations of the various languages.
There's always going to be pushback on new ideas. He's basically asking people questions like "Hey how does your thing work? I want to write it in rust." and gets the answer "I'm not going to learn rust.".
I think rust is generally a good thing and with a good amount of tests to enforce behavior it's possible to a functionally equivalent copy of the current code with no memory issues in future maintenance of it. Rewriting things in rust will also force people to clarify the behavior and all possible theoretical paths a software can take.
I'm not gonna lie though, if I would have worked on software for 20 years and people would introduce component that's written in another language my first reaction would be "this feels like a bad idea and doesn't seem necessary".
I really hope that the kernel starts taking rust seriously, it's a great tool and I think it's way easier to write correct code in rust than C. C is simple but lacks the guardrails of modern languages which rust has.
The process of moving to rust is happening but it's going to take a really long time. It's a timescale current maintainers don't really need to worry about since they'll be retired anyway.
From a developer standpoint you're taking someone's baby, cloning it into a language they don't understand and deprecating the original. Worse, if you're not actually interested in taking over the project you've now made it abandonware because the original developer lost heart and the person looking for commit counts on GitHub has moved on.
Obviously these extremes don't always apply, but a lot of open source relies on people taking a personal interest. If you destroy that, you might just destroy the project.
The video attached is a perfect example of the kind of "I'm not prepared to learn anything new so everyone else is wrong" attitude that is eating away at Linux like a cancer.
If memory safety isn't adopted into the kernel, and C fanaticism discarded, Linux will face the same fate as the kernels it once replaced. Does the Linux foundation want to drag its heels and stuff millions into AI ventures whilst sysadmins quietly shift to new kernels that offer memory safety, or does it want to be part of that future?
I am no visionary but if Linux doesn’t internalize this, I’m afraid some other kernel will do to it what it did to Unix.
Maybe that's not a bad thing? If you ask me the GNU people are missing a trick. Perhaps if they rewrote Hurd in Rust they could finally shed that "/Linux".
They will write kernel in Ada
