In the latest episode of On Rails, @robbyrussell is joined by @tenderlove from Rails Core and @Shopify's Ruby & Rails Infrastructure team. Aaron and Robby chat about how the team at Shopify has been making Ractors faster and more reliable, bringing true multi-core parallelism to Ruby, plus how and when you should actually use them.
