Rosa Gutiérrez (Programmer @37signals) - The curious incident... | Tropical on Rails 2025

Talk Title: The curious incident of the incomplete executor 🏆💬 Subtitles reviewed and approved by Jacqueline Almeida: LinkedIn: https://www.linkedin.com/in/jacqueline-m-almeida Rosa Gutiérrez, programmer at 37signals, brought an interesting story to the #TropicalOnRails 2025 stage with her talk, "The curious incident of the incomplete executor." Rosa shared an old, scary and tricky bug they faced while building HEY, the email service, how they figured out what happened and how it was ultimately fixed in Rails so that nobody would run into the same problem. Along the way, we learned a few things about the Rails Executor, a unsung hero that makes our lives much easier and is responsible for some of the Rails magic, as well as how simple techniques are often the most effective when chasing wild bugs. 🙏 A huge thank you to our Platinum sponsors — Shopify and Linkana — for making this event possible.
