Linus Torvalds muses about maintainer gray hairs and the next 'King of Linux'
Live from Vienna, it's the Linus Torvalds and Dirk Hohndel show! This time, they're talking real-time Linux, Rust, maintainer burnout, and succession planning.
In a candid keynote chat at the Linux Foundation's Open Source Summit Europe, Linux creator Linus Torvalds shared his thoughts on kernel development, the integration of Rust, and the future of open source.
People need to chill with the language fanaticism. It’s one thing to make jokes and rip on a language for its quirks, but at the end of the day it’s just a language. If you truly don’t like it, don’t use it. I’m going to take a stab and guess that there is enough Linux kernel source to go around to both the c devs and rust devs. Just be glad they’re not trying to rewrite it in JavaScript. 😉
The problem is that the Linux kernel is monolithic so introducing rust into it does have certain repercussions about downstream compatibility between modules.
Right now the rust code in the kernel uses c bindings for some things and there's a not-insignificant portion of C developers who both refuse to use rust and refuse to take responsibility if the code they write breaks something in the rust bindings.
If it was pure C there would be no excuse as the standard for Linux development is that you don't break downstream, but the current zeitgeist is that Rust being a different language means that the current C developers have no responsibility if their code refactoring now breaks the rust code.
It's a frankly ridiculous stance to take, considering the long history of Linux being very strict on not breaking downstream code.
Rust developers are fine with C bindings changing, they just want that to be communicated to them by the C developers before they break.
A valid point. But the result is that over a pretty short period of time. These C developers will find delays in how quickly their code gets accepted into stable branches etc. So will be forced to make clear documentation into how the refactoring effects other elements calling the code. Or move on altogether.
Sorta advantageous to all and a necessary way to proceed when others are using your code.
I agree.
I grew up in the age of c/c++ and then Java. I get it: people hate it and it’s time to move on, but jeez, folx, chill. It will happen in time, and there’s no reason to go all civil warsy about it.
Things like this should not be rushed.
Rust zealots are on an unstoppable jihad.
Expecting suicide fork bombers any day now.
A JavaScript VM in the kernel is inevitable.
No, a language is not just a language. I fact, it's a bunch of compilers. How many there are and the hardware they work on is what matters.
And as a matter of fact, rust isn't as much of an industry standard as C++ is.
I feel you’ve missed my entire point. My comment was not based on any technical merits of a language. It’s about a persons personal (religious) view of a tool they use to do their job.
I proudly use PHP, JavaScript, Java, Bash, and SQL. They have given me the means to make a long and fruitful 18+ year career. If my boss walked up to me tomorrow and said I needed to learn Python, or Rust, or even brainfuck, I’d learn it and be better for it.
Would it be as easy as my tried and true toolset? Not at first. I still remember the struggles I had when I was first learning my current toolset. It was frustrating. I remember cursing how stupid this or that was (especially PHP and JavaScript). But I learned, and now they’re not as frustrating — because I work with it, and not against it.
Look at JavaScript. Yeah it’s weird sometimes; if you don’t understand how it works. So people slap these transpiled languages or frameworks (like CoffeeScript or TypeScript or whatever) on top, trying to fix the things they think are wrong with JavaScript, and end up making a chaotic mess of the entire community. (And yes we could spend months arguing pros and cons of any merits of transpires and frameworks and why and what not, but then you’re still missing the point).
Anyway, the point is: if it works, then it’s good. Rust does not make Linux worse. If anything, it makes it better because it makes it more accessible to programmers who know Rust but not C. And that’s a good thing. It ensures the Linux kernel will be around longer than whomever ends up being the last C developer.
Those C developers bitching about how they don’t like the idea of rust in their kernel are akin to those old fogies yelling about those damned kids and their loud music or fashion sense.
Man I've never really thought about how much having the wrong successor could fuck up the whole ecosystem.
I'm wondering the same thing for Valve and Gabe Newell.
definitely the case for Valve. Corporate vultures will be all over it the second he's gone.
If they both decide to step down around the same time, that's going to be wild few years.
The things we take for granted are way too high.
It seems like you're missing a word
I have tracked down the missing word and returned it to its rightful place. Better late than never.
They apparently have accidentally the whole thing.
We will miss the days Linus was maintaining the Kernel... Who is going to write those poetic emails we all love?
People fear the same thing about Valve.
One wrong person and we could all end up in the same money milk machine as EA.
I know people complain about Linus hurling insults at merge requests, but his rigidness is what keeps the kernel viable. If it weren't for him, google would have already shit all over it with a mega fork and essentially cornered the market like they did with Android and HTTP3.
Both are technically "open source", yet Google essentially dictates what they want or need for their economic purpose, like ignoring JPEGXL, forcing AVIF, making browsers bloaty, using manifestv3, etc. Android is even worse and may as well be considered separate from Linux because it's just google's walled garden running on the linux kernel.
He is open to new technology, but he understands the fundamental effects of design choices and will fight people over it to prevent the project from fracturing due to feature breaking changes, especially involving userspace.
I would like for these people to never retire but we must all accept change as they come from father time
Where is that damn fountain of life when you need it?
with his death and the huge focus on trying to protect me from myself, I can see linux becoming even more restrictive than android. He's one of the few sane ones left.
I hope not. I’m not ready for the year of the BSD desktop.
I have a feeling it might go the other way, IE when he retires or whatever, everyone's going to want to be the "next Linus" and we'll end up with tons of different forks of kernels all following their own philosophy of what they think Linux should be.
I love that his desk is messy like mine and that he gets pissed at bad code.
I will be the next King of Linux.
What a unique and special position to be in.
It’s not common, and not likely to happen again.
Well if it doesn't happen again, that means Linux isn't doing well.
'it' being a handoff of ownership
