Part of being a good developer is the “working well with other human beings” part. Linus himself took a hiatus to improve himself in this area.
Another part of being a good developer is to work within and adapting to the frameworks of an existing project, especially if you are joining at a later point. In this context, it would be the R4L folks joining the project known as “the Linux kernel.”
Hector failed on both counts. He has programming skills, but that’s not all that’s required.
Sure, and part of being a good manager is to, you know, manage. It shouldn’t have gotten to the point that marcan is going outside the list to try to get something done. Linus (or someone else with authority, I’m not familiar with who else is managing it) should have stepped in much earlier to head off the drama. It was a very simple question.
Rust in the kernel is already established and part of the mainline kernel. It’s extremely pretty and wholly inappropriate to reject code just because it’s written in rust.
If you had read Christoph’s reasoning, it wasn’t “just because it’s written in Rust.” He actually gave some decent technical reasoning for it that went beyond his original personal outburst (which I hold him to the same standard as Hector for, but he did shore up later and fixed his communication).
The only two “technical” arguments I could see were firstly that code should
[remain] greppable and maintainable
which unless I’m missing something boils down to “I don’t speak Rust”, and secondly that
The only reason Linux managed to survive so long is by not having internal boundaries, and adding another language complely breaks this
which unless I’m missing something boils down to “I don’t speak Rust”, because ain’t nobody trying to add any other languages to the Linux code base.
Surely this can’t be the “decent technical reasoning” you are referring to? I have to admit I don’t follow kernel development that closely, but I was under the impression that integrating Rust into the code base was a long discussed initiative having the “official” blessing of the higher ups among the maintainers by now, so it seems odd to see it opposed in such harsh terms by a subsystem maintainer here:
I absolutely support using Rust in new codebase, but I do not at all in Linux.
You and i read different things. I hated how he worded them, but his arguments at greppable and understandable are valid arguments that go beyond rust and if he can read it or not or refuses to.
Mixing languages in a part of a project brings complexity and is often a huge ass nono because it makes things unreadable and hard to manage on a large scale.
He also argues that a c interface exists to connect 2 parts of a system. The person that changes the interface should not have to alter the users of that interface, if they do then you get intertwined dependencies, which is a huge ass red flag for developers that something has gone terrible wrong and the project is not going to scale or will be easy to change.
So if he changes the interface, the rust team will need to fix it, specially since they are the minority.
That also doesnt mean he can change it in whatever way without worry, it is an interface change, that needs discussions and approvals ahead of time ofc.
So now we’ve lost a very good developer, and the question of rust in the kernel remains unresolved. This is the worst possible outcome.
The times when a single developer was important to Linux were in the 90s.

Most full of shit comment in the thread
I don’t think this is the worst outcome. It would have been worse if he was the face of Rust in Linux and I’d died out over ten years instead of one.
That being said, hopefully it can get a fresh start.
