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.

I don't understand the obsession with rust.
From my personal experience I can tell you 2 reasons. The first is that this is the first general purpose language that can be used for all projects. You can use it on the web browser with web assembly, it is good for backend and it also is low level enough to use it for OS development and embedded. Other languages are good only for some thing and really bad for others. The second reason is that it is designed around catching errors at compile time. The error handling and strict typing forces the developer to handle errors. I have to spend more time creating the program but considerably less time finding and fixing bugs.
As much as I want to love Rust, that's not entirely true.
Writing a web API in Rust is a pain. It requires way too much boilerplate for very low level concepts. For example having to deal with all the lifetime crap in a simple CRUD endpoint. I understand why that's necessary, but compared to Python or Java it's just a very large mental load overhead.
You need less and less lifetimes as time goes on. The compiler gets better at inferring them and you could always use the heap if you wanted to or if what you are doing isn't very low level.
