Wedson Almeida Filho is a Microsoft engineer who has been prolific in his contributions to the Rust for the Linux kernel code over the past several years. Wedson has worked on many Rust Linux kernel features and even did a experimental EXT2 file-system driver port to Rust. But he’s had enough and is now stepping away from the Rust for Linux efforts.
From Wedon’s post on the kernel mailing list:
I am retiring from the project. After almost 4 years, I find myself lacking the energy and enthusiasm I once had to respond to some of the nontechnical nonsense, so it’s best to leave it up to those who still have it in them.
…
I truly believe the future of kernels is with memory-safe languages. 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.
Lastly, I’ll leave a small, 3min 30s, sample for context here: https://youtu.be/WiPp9YEBV0Q?t=1529 – and to reiterate, no one is trying force anyone else to learn Rust nor prevent refactorings of C code."
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.
That’s disengenuous though.
We’re not forcing you to learn rust. We’ll just place code in your security critical project in a language you don’t know.
Rust is a second class citizen, but we feel rust is the superior language and all code should eventually benefit from it’s memory safety.
We’re not suggesting that code needs to be rewritten in rust, but the Linux kernel development must internalise the need for memory safe languages.
No other language community does what the rust community does. Haskellers don’t go to the Emacs project and say “We’d like to write Emacs modules, but we think Haskell is a much nicer and safer functional language than Lisp, so how about we add the capability of using Haskell and Lisp?”. Pythonistas didn’t add Python support to Rails along side Ruby.
Rusties seem to want to convert everyone by Trojan horsing their way into communities. It’s extremely damaging, both to those communities and to rust itself.
It doesn’t help that the Rust community tends to bring extremely divisive politics with it in places and ways that just don’t need to happen, starting battles that aren’t even tangentially related to programming.
That is the most sensible look into this so far.
Ok, but why shut out the rust developers just because some dilettantes idolize rust? At that point the rust developers might as well rewrite everything in rust.
There is no good reason to shut out well meaning Rust developers just because of a few annoying members of the community. I think that’s just some context to keep in mind when seeing people get annoyed when told to consider Rust instead of what the project is already written in, or when approaching someone with the idea of including Rust in their project. Open source in general could use a lot more empathy; it’s a lot of thankless work and the main thing you hear from the community is often criticism.
