Explore Ruby 3's new Ractor feature for thread-safe concurrent and parallel execution in this 25-minute conference talk. Learn how Ractor allows Ruby programmers to engage in parallel programming without common thread-safety issues by maintaining object isolation. Discover the power and limitations of Ractor through an interactive demonstration, including restrictions on global variable usage in multi-Ractor programs. Gain insights from Koichi Sasada, a key Ruby interpreter developer and Ruby Association director, as he introduces this important abstraction for concurrent programming in Ruby.
