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.

Redox OS - an OS built entirely out of Rust (www.redox-os.org)

This isn't Linux, but Linux-like. Its a microkernel built from the rust programming language. Its still experimental, but I think it has great potential. It has a GUI desktop, but the compiler isn't quite fully working yet.

Has anyone used this before? What was your experience with it?

Note: If this is inappropriate since this isn't technically Linux, mods please take down.

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.

I feel like C++ is as competent as Rust for any project and it's definitely older.

Before using Rust I was using C++ for most projects and while it is a really powerful language there were some big problems:

no standard build system, most projects use cmake or meson and vendor dependencies with the projects. These build systems were really hard to learn (especially cmake, meson is easier). There are package managers these days such as conan and vcpkg but there is not really one standard way to build programs like in rust.
error messages were really hard to understand, especially when the project uses templates
it felt like 3 languages in one, projects written before c++11 differ greatly from c++11 and up
some of the new language features have really weird syntax, for example lambdas
some people say that rust is hard, but modern c++ is considerably harder to learn, just look at the list of modern c++ features: https://github.com/AnthonyCalandra/modern-cpp-features, you have to know the different pointer types (unique_pointer, shared_pointer etc.), templates, rvalue references and move semantic, exceptions, constexpressions and the list goes on

At least it won't complain about rigid, skolem or occurrence check.
