☁️ **Clouders, ¡bienvenidos al meetup presencial de mayo del AWS User Group Medellín!** 🎉 En colaboración con **RIWI.IO** Un espacio para inspirarte, aprender y seguir construyendo tu camino en la nube. 📅 **Sábado 16 de mayo de 2026** 🕤 **9:30 AM - 12:00 PM** 📍 **Calle 16 # 55-129, Piso 3, Outlet — Auditorio** 🎟️ **Entrada gratuita** 👥 **Presencial** *** **Certificaciones, Seguridad y el Futuro Tech: lo que nadie te cuenta** Tendremos dos charlas pensadas para ti: una para entender cómo las certificaciones impactan (o no) tu carrera tech, y otra para dominar la seguridad en AWS desde IAM hasta agentes de IA. *** 🎤 **CHARLA 1: Sin certificación, ¿Hay contratación?** **Speakers:** **Diana David** — IT Recruiter, HR Manager y Mentora Tech Psicóloga con más de 8 años de experiencia en el sector tech. Ha trabajado en compañías con presencia internacional y acompañado procesos de mentoría para perfiles tech que quieren impulsar su carrera a nivel global. **Lucas Vera** — AWS Community Builder, Arquitecto Técnico y Desarrollador Full-Stack Más de 11 años en desarrollo de software y +5 años como entrevistador técnico en procesos de selección para perfiles de ingeniería. Especializado en soluciones serverless sobre AWS. ¿Cuánto pesa una certificación en la industria? ¿Cómo sobresalir si no se tiene alguna? ¿Cómo hacer la diferencia cuando sí se tiene una? Dos perspectivas — recruiting y técnica — en una sola conversación. *** 🔐 **CHARLA 2: IAM, Perímetro e IA: Un Recorrido Práctico por la Seguridad en AWS** **Speaker: Juan David Alvarez Builes** — Senior Cloud Security Consultant en AWS ProServe Ingeniero de Sistemas de la Universidad EAFIT. +15 años en ciberseguridad y arquitectura TI. 13 certificaciones AWS activas + CISM. Speaker en RSA Conference 2026 y Ekoparty 2025. Basado en Medellín. Un recorrido práctico desde las bases: identidad y control de acceso con IAM, controles de perímetro organizacional como SCPs y RCPs, y los servicios clave de seguridad en AWS — todo con lecciones aprendidas reales y **demo en vivo**. Porque cuando un agente de IA actúa en nombre de un humano, cada política que no esté bien definida se convierte en una superficie de ataque a velocidad de máquina. *** **¿Qué incluye el evento?** ✔ Networking con la comunidad cloud de Medellín ✔ Dos charlas técnicas y de carrera ✔ Espacio para preguntas y debate con los speakers ✔ Snacks **¡Regístrate y asegura tu lugar!**

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
