• Be curious, not condescending
• Show your work—code, demos, and "here's what broke" stories welcome
• Demos > debates. Disagree? Show us a better way
• No gatekeeping. Explain the why, not just the what
• Celebrate failures. We've all deployed to prod on Friday
• Keep it technical
• Be kind to future you—document your solutions
TL;DR: Help each other build cool stuff. Don't be a jerk. Bring demos.
