Are you wanting to get unstuck from unconscious blocks that are sabotaging your life? Are you ready to see your future clearly and follow your heart's desire? Family Constellation is soulful work that was developed by Bert Hellinger in Germany. Use it to become empowered to get the health, wealth, love, and for issues proving difficult to treat with traditional therapy. Learn highly effective techniques to liberate yourself from patterns and reawaken your vitality, confidence, and joy! Move forward in life with renewed purpose. A constellation provides a “living map” of key impactful issues and leads you towards the restoration of balance, order, harmony and healing. Each of us, whether participant or observer, taps into information that exists and benefits from the knowledge. The real power is knowing where we came from, where we belong and where we want to go. You will also learn how to identify the unconscious loyalties, unresolved traumas, and hidden dynamics that contribute to patterns of illness, complaint, and disappointment. This energy field therapy provides assistance to make peace with the past, freeing us to reside in the present, and to generate a new fulfilling future. BIOGRAPHY Randy Goldberg LMT is a graduate of the DC Hellinger Institute, and of advanced studies in Family Constellation with Heinz Stark of Germany. He is a former Yoga monk, Craniosacral therapist, and a world renowned-astrologer (both Western and Vedic) interviewed by the Washington Post, NPR, and CNN. He facilitates Family Constellation therapy for individuals and groups.

HYBRID EVENT, VIRTUAL SPEAKER In this talk, Sean Hoar will explore the transformative journey of AI’s role in modern software engineering, from rapid prototyping (“Vibe Coding”) to strategic AI integration by skilled practitioners. It clarifies the distinctions between AI-assisted, AI-enabled, and practitioner-led approaches, offering insights into how developers can effectively adapt to and harness AI tools. The presentation also highlights recent advancements and practical strategies for leveraging AI in daily workflows and long-term development.

**The Test Tribe 2nd Washington Meetup – Designing a Modern QA Organization: Structure, Skills, and Shared Ownership** AI is accelerating software delivery at an unprecedented pace-but speed without structure introduces serious risk. In today’s landscape, the traditional “testing bottleneck” isn’t just a delay-it’s a business liability. This session explores how Quality Engineering must evolve from a siloed function into a strategic, distributed capability-one that balances rapid AI adoption with strong human oversight. Moving beyond basic automation, this talk introduces the concept of Distributed Quality Governance, where quality becomes a shared responsibility across engineering, product, and leadership. Expect a practical, leadership-focused discussion that cuts through AI hype and addresses the real challenges of testing complex, AI-assisted systems-while ensuring accountability, trust, and long-term resilience. **Event Details** * **Date: 21st January 2026 (Wednesday)** * **Time: 6:00 PM – 8:00 PM EDT** * **Location: 1501 Langston Blvd. Arlington, Virginia** **Session: Designing a Modern QA Organization: Structure, Skills, and Shared Ownership** **Speaker: Alekhya Guduri** **About the Session** In an era where AI-generated code is accelerating delivery, quality can no longer be treated as a final checkpoint. Instead, it must be embedded, intentional, and governed. In this session, Alekhya Guduri presents a blueprint for building a modern QA organization that operates as a strategic business function. You’ll learn how to shift from centralized testing teams to shared ownership models, while introducing guardrails that ensure responsible AI use across the delivery pipeline. From defining a Materiality Matrix to identify where AI risks are too high to ignore, to implementing Human-in-the-Loop frameworks, this talk provides actionable guidance for leaders navigating AI-driven engineering environments. **Key Takeaways** * The Materiality Matrix: How to objectively prioritize AI risks based on business impact and technical complexity * Distributed Governance: Transitioning from centralized QA to shared ownership in AI-driven CI/CD pipelines * Responsible AI Guardrails: Practical Human-in-the-Loop frameworks to prevent bias, hallucinations, and silent failures **About the Speaker** Alekhya Guduri is a seasoned technology leader whose career sits at the intersection of engineering execution, operational excellence, and innovation. As Director of Engineering at Indeed, she focuses on building high-performing organizations that treat quality as a strategic advantage, not a last-mile activity. With deep experience scaling complex systems and leading cross-functional teams, Alekhya works at the forefront of shaping how AI and human judgment coexist within modern software delivery. She is a strong advocate for distributed governance, responsible AI practices, and the evolution of Quality Engineering into a trusted business partnership. **Why You Should Attend** * Learn how to design QA organizations for AI-driven delivery * Understand how to balance speed with responsibility in modern pipelines * Gain leadership frameworks for shared ownership of quality * Move beyond AI hype to practical, defensible testing strategies * Connect with Washington-area QA, engineering, and tech leaders **About The Test Tribe** **The Test Tribe** is the world’s largest software testing community, empowering testers globally since 2018. With 7**00+ events** and **150K+ members** across **130+ countries**, we bring testers together to learn, grow, and connect through meetups, conferences, cohorts, masterclasses, and more.

Join us for another session of our study group as we dive into the fascinating world of Large Language Models (LLMs) using the book **Build a Large Language Model from Scratch** from Manning. In this session, we will finish **Chapter 7: Fine-tuning to follow instructions**. In the last session, we talked about how to prepare the dataset for instruction fine-tuning and in this session we will perform the fine-tuning and evaluate the model afterwards. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to build a strong foundation together. If you plan to work with the code on your own laptop during the session, try and set-up the environment ahead of time (https://github.com/rasbt/LLMs-from-scratch/tree/main/setup). We will be meeting at the North County Governmental Center this time that is across from the Reston public library.

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it!
