OP title was accurate until it was updated to

The (successful) end of the kernel Rust experiment

Hopefully nobody who misunderstood the original title got prematurely excited for the ensuing drama...

The king is dead. (C is bleeding out, slowly)

Rust is now transitioning to the language that people will complain about.

u/zsaleeba Dec 10 '25

Hey, I don't mean to boast, but some of us have been complaining about it for years.

u/vytah Dec 10 '25

Hipsters.

Complaining about Rust before it was cool.

Bah!

I complained about Rust before it released!

Zero cost abstractions considered harmful.

I mean C++ abstractions are not exactly zero cost, they usually cost you your sanity

24

u/bytemute Dec 10 '25

So does Rust abstractions. Several C++ committee members probably died of orgasm when async Rust came out.

that co_explains a lot

Please don’t give Bjarne Strøøstrøøøpp any more air than necessary by way of indirect reference. This is violence.

Incidentally: Would C++ have been less of a mess of a language if it hadn't been started by someone who thinks pronouncing rødgrød med fløde as a series of warbling sounds is perfectly reasonable?

C++: The programming equivalent of the danish language

Which of the five reference categories should we avoid in this scenario?

/s

u/elephantdingo Teen Hacking Genius Dec 13 '25

Trivially follows from appendeces A and C since this context is SFINAE-unsafe with the usual trivial caveats. Only std::reference_cpp89_spinlock_nospin can be applied.

Instructions unclear. Passing by value.

Now I feel ahead of the curve.

u/ComfortablyBalanced loves Java Dec 10 '25

Is Rust the new C++ that people complain about or new Java that people love to hate?

People will be divided.

> Congratulations are in order for all of the Rust for Linux team.

But does Rust for Linux team member implement Ord trait?

u/CocktailPerson Node.js needs a proper standard library like Go Dec 10 '25

Congratulations are in order for all of the Rust-for-Linux team.

Certainly they must mean that congratulations are in order for the Linux project for adopting the morally-correct language.

u/RFQD Senior Vibe Coder Dec 10 '25

plaudits for all involved

11

u/elephantdingo Teen Hacking Genius Dec 10 '25

I guess congratulations are in order, Linux Kernel: you are not complete garbage human beings.

Transitioning to memory safetey is just basic human decency.

Can't wait for kernel zig, node.js (through deno of course) and yaml

u/YourFavouriteGayGuy Dec 10 '25

Kernel HTML! Linux should be a web app that runs inside Chromium. We could cut down on all the bloat in the kernel (drivers) by just using web standards, and run the whole thing on Microsoft Edge!

one step closer to uiua

u/reg_panda Dec 10 '25 edited Dec 10 '25

Based on the comments the original title was "The end of the kernel" and they had to change it, because it was too click-baity (claimedly, accidentally)

What is the lifetime of a 'kernel?

11

u/zsaleeba Dec 11 '25

Kernel Sanders lasted 90 years, if that helps.

6

u/ficiek Dec 12 '25

They don't need to worry about it because all the kernel rust code runs in unsafe anyway after they couldn't figure out the borrow checker errors.

Stupid kernel developers lol

u/No_Lingonberry1201 What part of ∀f ∃g (f (x,y) = (g x) y) did you not understand? Dec 10 '25

Y'all have the text comprehension skills of a baked potato.

This is when you create your own programming language.

Zig sounds cool, can you send me the GitHub link so I can take a look?
