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.

Right, a stack that was itself read-only would be hard to use! :^D C definitely lets you modify the things in the stack. (Ah the fun of bugs where you accidentally overwrite other shit on the stack!) I don't know Rust, but it would not surprise me if Rust only had immutable things on the stack.
No, its not only immutable things on the stack. I mean if you include a literal constant string such as "MIT LICENSE", that is part of the compiled binary file. So it is unchangeable. Because you cannot change a literal, a "1" is always a "1" in the compiled binary file. And those are basically read only by their nature and loaded into the stack. I think or guess in C it is the same. Or any language for that matter.
I started to think I was hallucinating. I guess what I was thinking is this part https://en.wikipedia.org/wiki/Data_segment . There are read-only data segments too.
