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.

Could you specify some kind of example where things were hard?
I'll try :) Looks like I still have my code from when I was grinding through The Book, and there's a couple spots that might be illuminating from a pedagogical standpoint. That being said, I'm sure my thought process, and "what was active code and what was commented out and when," will probably be hard to follow.
My first confusion was in ~~deref coercion~~ auto dereferencing (edit: see? it's still probably not 100% in my head :P), and my confusion pretty much matched this StackOverflow entry:

It took me until Chapter 15 of The Book (on Boxes) to really get a feel for what was happening. My work and comments for Chapter 15:
Another thing that ended up biting me in the ass was Non-Lexical Lifetimes (NLLs). My code from Chapter 8 (on HashMaps):
That's insightful, thank you. It wasn't hard to follow, I did have these exact same "adventures" but I guess I forgot about them after I figured out the ways to do things.
Personally these kinds of things are exciting for me, trying to understand the constraints etc, so maybe that's also why I don't remember struggling with learning Rust, since it wasn't painful for me 😅 If someone has to learn by being forced to and not out of their own will, it's probably a lot harder
