With Ruby installed, you can now manage your RubyGems with the gem command. Install the Rails gem or update if you already have it.

The Rust book

My first port of call was to google learn rust which lead me to "the book". The book is a first steps guide written by the rust community for newbies (or Rustlings as they're called) to gain a 'solid grasp of the language'.

Before Prodzilla, I’d read 'The Book' a couple of times, and had made my way through Rustlings, but hadn’t yet built a serious project in Rust.

To answer your last question;

Start with the Rust book.

https://doc.rust-lang.org/book/

Then do Rustlings until the syntax becomes muscle memory.

Then join the Discord and start doing little projects.

You won’t get up to the proficiency of other languages as quickly in Rust. It takes longer. For me it’s taking a lot longer, but I enjoy it.

Before diving into these repositories, familiarize yourself with Rust and its development ecosystem. The official Rust book is an excellent resource for developers at all levels. Each repository has documentation on how to contribute, covering code style, issue tracking, and pull requests.

This is my third Rust book after the official book and Rust in Action. The other two books are great, but they were too theoretical for me. I'm a slow learner and had much trouble grokking Rust's features and idiosyncrasies. When I was done with these books, I was lost and unsure of what I could do.

It's the same reason everything digital and downloadable isn't free: there's a cost to create it and there's a value to it.

For a language developer to charge for a book about that language, I think that's a completely valid way to make some money off of their work.

Even the Rust book, "The Rust Programming Language" is available freely online [0], but also as a print and ebook for sale via NoStarchPress [1].

You know you can just read it online right now in 2 different variants It does contain some systems programming.
