 If none of the stuff above seems like the next step, I hope I at least have given you the language you need to find it. Remember that language is power, and knowing the terms above will definitely help you do more effective searches in the Reactive and event driven spaces.

+I think the best way to get started with Rust is to read [[https://doc.rust-lang.org/stable/book/][The Rust Programming Language book]] (also available as a physical book in any bookstore that sells programming books), and do [[https://github.com/rust-lang/rustlings][Rustlings]] exercises while reading it (interactive exercises!). The next steps will probably be to hack away at your own projects, open source code etc. If you still find Rust interesting, I can recommend Rust Brain Teasers by Herbert Wolverson. It is in the style of books like Java Puzzlers, where you are presented with edge cases and weird behavior and should guess what happens (i.e, if it compiles, what it prints etc.).

-For those of you who may have read this article, and are familiar with Rust, you might want to go deeper. Maybe you want to know more about how everything works under the hood? More advanced concurrency and parallelism? Unsafe code? Other efficiency tricks, and things needed for embedded Rust? Then I can recommend [[https://amzn.to/4hkBmG5][Rust for Rustaceans]]. The author, Jon Gjengset, also have [[https://www.youtube.com/c/JonGjengset][a YouTube channel]] where he goes through intermediate Rust concepts (maybe there is some newbie friendly as well?).
