David recaps Blue Ridge Ruby and talks about coming back motivated to contribute more to open source, which leads into a broader discussion on why smaller single-track Ruby conferences create better hallway conversations, networking, and lightning talks. We also get into real-world Rails and Stripe lessons covering workshop prep, validation decisions, webhook recovery, subscription edge cases, and the growing complexity of payment integrations.
