Join the Bitcoin District Book Club! We meet every month to explore new and exciting rabbit holes by reading books that are popular with bitcoiners. Join us for a deep dive into *The Fourth Turning: An American Prophecy* by William Strauss and Neil Howe. In this session, we’ll explore one of the most influential modern frameworks for understanding historical cycles and generational change—and why its predictions seem increasingly relevant today. Strauss and Howe propose that history moves in recurring cycles, or “turnings,” each lasting roughly 20–25 years and shaped by generational archetypes. According to their model, societies pass through four phases: a High, an Awakening, an Unraveling, and finally a Crisis—the “Fourth Turning.” This final phase is marked by institutional breakdown, social upheaval, and a restructuring of the political and economic order. We’ll discuss where we might currently sit within this cycle, how past Fourth Turnings (like the Great Depression and World War II era) unfolded, and what this framework suggests about the coming decade. For those interested in macro trends, generational dynamics, and long-term historical patterns, this book offers a provocative lens for interpreting today’s instability—and what may come next. Buy the book on [Amazon](https://a.co/d/0dNwKse5) **Event Notes:** * Discussion Starters: We’ll kick things off with a few key questions around generational cycles and crisis periods, but feel free to bring your own perspectives. * Future Reads: Let us know if you have recommendations for future book club selections! We’ll add them to the list posted [on our website](https://bitcoindistrict.org/bookclub). * Afterwards: Feel free to join us at Pubkey after the meeting to hang out, continue the conversation, and grab some food! **Getting There:** * 🔴🟢🟡 Gallery Place/Chinatown + 2 min walk * Parking: Street & garage parking available nearby

Hands-on learn how to save life & limb, when mired in the wilderness of an urban disaster zone, travel or rural area far from hospital, or natural area miles from an access point, during the critical minutes or hours before ambulance arrival. Come away with actual do-it-yourself care-giving skill and confidence, and 2-year SOLO certification. Counts as WFR Recertification, too. No prerequisites. YOUR SPOT IS NOT RESERVED UNTIL YOU'VE COMPLETELY REGISTERED AT WWW.SOLOWFA.COM \***Spaces are limited. REGISTER: www.solowfa.com or 434.326.4697** Can't make these dates? Check out more course locations and dates on our website. WHO: Open to the general public, adults & teens with solid attention spans. Know your loved ones are safe wherever they are. WHY: Mired in a disaster zone, travel or rural area far from a hospital, or natural area miles from an access point ... accidents, destructive weather, and terrorism happen, and all-too-often members of a group are not capable of dealing with the emergency. This leads to improper care of the patient, and endangers the entire group. Many recreational accidents are preventable, and improper care of trauma can compound even simple injuries. Very few first aid programs actually address the issues of providing emergency care in a setting where 911 is overwhelmed or not immediately reachable. In this course, classroom instruction and Q&A are interwoven with practical work and problem-solving exercises. Hands-on experience - a most powerful learning tool - during scenarios comprise \~50% of class. TIMING: This is a 2-day class, Saturday and Sunday, 8:00am -7pm each day. Fee: $295 (Earlybird)

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
