Sendagaya.rb #537

The 537th Sendagaya.rb meetup runs online over Google Meet. Note that the start time has been moved to 21:00. After self-introductions, participants decide together on the spot which topics the session will cover. Candidate topics include talks that caught people's attention at RubyKaigi 2026 and Kaigi on Rails 2025, questions about problems attendees are stuck on in their own development work, reading through the Rails Guides and the security guide, group reading of Ruby Under a Microscope and the Rails chapters of Metaprogramming Ruby, going through the Rails 7.1 changelog, and digging into REST architecture and how OpenID Connect works. The agenda is not fixed and shifts with what attendees ask for. The rough timeline is doors and self-introductions at 21:00, one topic at 21:30 and a second at 22:00, with the session wrapping up around 22:30 (an extended session sometimes runs until about 23:00). Bring a laptop. The community uses Slack for questions and sharing links between members.
