Since February, there've been 800 newly assigned CVEs. Your job? Update your main Linux distro more often.

Great reason to push more code out of the kernel and into user land
Is it HURD'n' time?
I dunno, Stallman, it's been 30 years, you got something for us?
I think we should just resurrect Plan 9 instead.
Plan 9 is also monolithic, according to wikipedia. For BSD it depends.
I mean, you're right but I still want to see a modernized plan 9, I just think it would be neat.
that would be Inferno
Latest release was 9 years ago, not exactly what I'm looking for. 9front is probably closer to what I want than inferno.
Ah shit MIT license
Is that bad?
It means anyone including microsoft or apple can use the code contribution or take the entire softwarw and make some modifications and sell it proprietary. Any optimisations or features made by community can be proprietarised
Interesting, but why implement yet another windowing system?
L4. HURD never panned out, and L4 is where the microkernel research settled: Memory protection, scheduling, IPC in the kernel the rest outside and there's also important insights as to the APIs to do that with. In particular the IPC mechanism is opaque, the kernel doesn't actually read the messages which was the main innovation over Mach.
Literally billions of devices run OKL4, seL4 systems are also in mass production. Think broadband processors, automotive, that kind of stuff.
The kernel being watertight doesn't mean that your system is, though, you generally don't need kernel privileges to exfiltrate any data or generally mess around, root suffices.
If you want to see this happening -- I guess port AMDGPU to an L4?
seL4 is the world’s only hypervisor with a sound worst-case execution-time (WCET) analysis, and as such the only one that can give you actual real-time guarantees, no matter what others may be claiming. (If someone else tells you they can make such guarantees, ask them to make them in public so Gernot can call out their bullshit.)
That bit on their FAQ is amusing.
So what you are saying is “mach was right”?
Everybody knows it was. Even Linus said a microkernel architecture was better. He just wanted something working “now” for his hobby project, and microkernel research was still ongoing then.
