A JIT compiler for Ruby with Aaron Patterson | Open Source Thursdays
Aaron Patterson (tenderlove) is a Senior Staff Engineer working at Shopify where he is focusing on Ruby core and Rails core development.
We’re going to work on a Just-in-time (JIT) compiler for Ruby that’s written in Ruby! 💎
We’re going to start by building a JIT for Ruby from the ground up. First, we’ll learn how Ruby’s virtual machine works, then talk about the CPU itself. Finally, we’ll start building a JIT for Ruby in Ruby.
