From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It’s Ted Ts’o, the maintainer of the ext4 filesystem amongst other things.
Though you’re still accurate despite his seniority.
There's really only one valid response to Ted Ts'o:
If you think you can do better with C, prove it.

You seem really invested in pointing out those shortcomings. I respect that.
Arrogant hypocrites are a pet peeve of mine. If someone is going to act like progressive technology changes are beneath them and unnecessary, they should be able to put their money where their mouth is.
Somebody needs to send a public email to the kernel mailing lists with this
How many vulnerabilities have the kernel Rust team introduced in the same time period on the same code?
Let me know when you find one?
Memory ownership isn't the only source of vulnerabilities. It's a big issue, sure, but don't think rust code is invulnerable.
Of course. Rust isn't immune to logic errors, off-by-one mistakes, and other such issues. Nor is it memory safe in
unsafeblocks.Just by virtue of how memory safety issues account for 50%+ of vulnerabilities, it's worth genuinely considering as long as the bindings don't cause maintainability issues.
The bindings cause maintainability issues. That's the problem.
