Linux

I took notes for the benefit of anyone who doesn’t like their info in video form.

I love you.

This is a great summary. Thanks!

So probably there will be some systems other than Linux that do use Rust

There's one called Redox that is entirely written in Rust. Still in fairly early stages, though. https://www.redox-os.org/

Good human.

On a tangential note, what does Linus used, Vi or Emacs?

Thank you for the summary!

Doing the lord's work, thank you.

So probably there will be some systems other than Linux that do use Rust.

Isn't there Redox OS?

Edit: yes, it's still alive and kicking.

vi versus emacs

You write "vi versus the world" funny.

I think it can be summed up to C is more mature than Rust so we wait for Rust to shine Rust can overcome some complex things in C and vice versa

How is it that no matter what the damn topic is, Linus always seems to be the most level-headed in the room? I really admire him for that...

Edit: Lol, Linus, not Linux. Linus. xD

Thank you for the write-up!!

I think you're correct except for "having Rust in the Kernel is a bet on the future". That's something the techbro's would say.

The existing maintainers won’t live forever, having Rust in the Kernel is a bet on the future.

You're drastically reducing your talent base by requiring membership in two groups of experts. Well done.

The comma splice gives it away, but you're new at organizing groups and practicing set theory, aren't you?

FWIW, it's a 9 min video and doesn't contain anything earth shattering or easily summarized. Basically there is some friction between C and Rust devs, and Linus doesn't think that it's such a bad thing (there has be interesting discussion) and it's way too early to call Rust in the kernel a failure.

Rust is harder to write but infinitely safer, and equivalent in speed.

I also dont like videos for this stuff. Summarized using kagi's universal summarizer, sharing here:

• The integration of Rust into the Linux kernel has been a contentious topic, with some long-term maintainers resisting the changes required for memory-safe Rust code.
• The debate over Rust vs. C in the Linux kernel has taken on "almost religious overtones" in certain areas, reflecting the differing design philosophies and expectations.
• Linus Torvalds sees the Rust discussion as a positive thing, as it has "livened up some of the discussions" and shows how much people care about the kernel.
• Not everyone in the kernel community understands everything about the kernel, and specialization is common - some focus on drivers, others on architectures, filesystems, etc. The same is true for Rust and C.
• Linus does not think the Rust integration is a failure, as it's still early, and even if it were, that's how the community learns and improves.
• The challenge is that Rust's memory-safe architecture requires changes to the existing infrastructure, which some long-time maintainers, like the DRM subsystem people, are resistant to.
• The Linux kernel has developed a lot of its own memory safety infrastructure over time for C, which has allowed incremental changes, whereas the Rust changes are more "in your face."
• Despite the struggles with Rust integration, Linus believes Linux is so widely used and entrenched that alternative "bottom-up grown-up from the start Rust kernels" are unlikely to displace it.
• Linus sees the embedded/IoT space as an area where alternative kernels built around different languages like Rust may emerge, but does not see Linux losing its dominance as a general-purpose OS.
• Overall, Linus views the Rust debate as a positive sign of the community's passion and an opportunity to learn, even if the integration process is challenging.
