Programming languages tend to polarize, and Rust is by far no exception. Whether it will stick around and grow as an alternative for the lower levels or not — time will tell. In the meantime, if you're curious about the language and its low-level abilities yourself, [phil-opp] has written a series of blog posts on building your own little bare metal kernel in Rust.

Starting from the basics, [phil-opp] describes in detail the set-up and build process to create a standalone executable that won't be linked against the Rust standard library. From here he proceeds to build a simple operating system kernel that prints a good old Hello World via VGA output — QEMU emulation included. And of course, there is a GitHub repository with all of the source code.

  "while ( true ) ;"

  I prefer to write "for (;;)" which I read as "forever".

  I was taught that

  for (;;)

  is the preferred idiom because the parser recognizes it as a unique situation. The while-loop looks like any other while-loop in the parse tree. Of course any compiler that didn't ultimately optimize them to the same code is an awful compiler.
