Agenda
Ruby in Parallel: Fibers, Ractors, and Ruby 4
Sam Burns says:
Ruby 4 builds on Ruby 3’s concurrency features, introducing refinements to Fibers and Ractors. This milestone in the language’s evolution transforms concurrency from an experimental frontier to a production-ready reality.
This talk provides an up-to-date guide to Ruby’s modern concurrency toolkit, from the lightweight efficiency of Fibers to the parallel power of Ractors.
Join us to explore the core concurrency features of Ruby, and get an up-to-date picture of the latest developments in Ruby 4.
Afterwards
When the talks come to an end we’ll decamp to a local pub for some food, some drinks and some chat with your fellow attendees.
Of course, even though this is the socialising part and seems more informal, please remember that still we consider it to be a part of the meeting and covered by our code of conduct.
