RailsConf 2022 - A Rails Developer’s Guide To The Ruby VM by Maple Ong - YouTube

What happens under the hood when you run a Ruby script as simple as puts “Hello World!”?Time to switch gears from the Rails-level of abstraction to a lower one and dive into some Ruby internals. We’ll be learning about how the Ruby code you write gets compiled and executed, then zoom in to the VM-level – what VMs are and what they do, and how the Ruby VM works. You’ll walk away with a better understanding of how Ruby and Rails works as a whole. No low-level systems knowledge needed!.
