Sendagaya.rb #531

Sendagaya.rb is a regional Rubyist community based in the western part of Tokyo, and this is its online meetup #531 held over Google Meet. The start time is 21:00. The session covers topics people found interesting at RubyKaigi 2026 and Kaigi on Rails 2025, consultations about development problems, and individual project work, all run loosely according to what participants bring. Candidate themes include reading through the Ruby Hacking Guide, the Rails Guides, and the security guide, reading books such as Ruby Under a Microscope and Metaprogramming Ruby, reviewing the Rails 7.1 changelog, and studying REST architecture and OpenID Connect. These are tentative, and the actual themes are decided by discussion on the day. The timeline is 21:00 doors and self-introductions, talks from 21:30, and a planned wrap-up at 22:30 (with an extended session sometimes running until around 23:00). People who want to discuss Ruby and Rails as well as beginners are welcome; bring a laptop and join casually.
