👋🏼 This is part of series on concurrency, parallelism and asynchronous programming in Ruby. It’s a deep dive, so it’s divided into several parts: Your Ruby programs are always multi-threaded: Part 1 Your Ruby programs are always multi-threaded: Part 2 Consistent, request-local state Ruby methods are colorless The Thread API: Concurrent, colorless Ruby Bitmasks, Ruby Threads and Interrupts, oh my! (Concurrent, colorless Ruby) When good threads go bad: Concurrent, colorless Ruby Thread signal handling: Concurrent, colorless Ruby Thread and its MaNy friends: Concurrent, colorless Ruby Fibers: Concurrent, colorless Ruby Processes, Ractors and alternative runtimes: Parallel Ruby Scaling concurrency: Streaming Ruby Abstracted, concurrent Ruby Closing thoughts, kicking the tires and tangents How I dive into CRuby concurrency You’re reading “Bitmasks, Threads and Interrupts, oh my!
