What if the best product requirement was a working prototype? Amazon built an empire on one principle: start with the customer and work backwards. Identify the durable need. Resist building until you know what you're solving - and for whom. Vibe coding doesn't abandon that discipline. It supercharges it. Join us for an in-depth discussion on how natural language becomes structured specs, specs become architecture, and architecture becomes working software - in real time, in the room, on your machine. Whether you're validating a product idea or accelerating a team's delivery, this is where the “Working Backwards” mindset meets the AI-native development stack. **Featured speaker:** * [AJ Bubb](https://www.linkedin.com/in/ajbubb/), Innovation Strategist and AWS veteran - for a hands-on session exploring Spec-Driven Development with AWS Kiro. \~ "*We're not just talking about it.

Mindfulness Meditation group practice every Wednesday evening at Unity of Gaithersburg. Mindfulness practice is not about achieving some special state of mind; it is more about noticing the experience you are having without trying to change it. This interesting video suggests why you might sit and watch your mind wander off. https://www.youtube.com/watch?v=DmmBF8eTl18 This noticing tends to shift your nervous system from a 'fight-or-flight' state to a more relaxed and receptive state. In this receptive mental state, you begin to see your own experience differently and, over time, see other people and the world differently. Also, it is good for you: "the effect of regular meditation on the cortex was so profound that fifty-year-old meditators had a prefrontal cortex that looked like that of a twenty-five-year-old" [https://www.amazon.com/gp/product/B07PLRZVTT](https://www.amazon.com/gp/product/B07PLRZVTT) Here is an interesting and funny take on meditation by Ajahn Brahm: [https://www.youtube.com/watch?v=TR60RRmXeYs](https://www.youtube.com/watch?v=TR60RRmXeYs).

MCKS PRANIC HEALING® Level I In PRANIC HEALING® Level 1, you learn the basics of working with your energy aura, including learning to "scan," or feel the energy, to "sweep," or clean away congested energy, and to "energize," or supplement areas in your aura that have a pranic deficiency. PRANIC HEALING® has been taught to doctors, nurses, massage therapists, acupuncturists, chiropractors, shiatsu practitioners, and many others in the healing field. It has allowed them to heal confidently and consistently in the shortest learning time possible. These professionals find PRANIC HEALING® very effective and easy to apply. Other topics covered in PRANIC HEALING® Level 1: Energetic anatomy: You will learn to work with the network of chakras, meridians and auras to accelerate the healing processes of your body. Preventive healing: You will learn to remove the negative energetic patterns of a disease to prevent it from fully manifesting as a physical ailment. Self-Pranic healing: You will learn to apply these healing techniques to accelerate your own healing. Step-by-step techniques for ailments related to your: respiratory system, e.g., asthma,; circulatory system, e.g., heart ailments; gastrointestinal system, e.g., irritable bowel syndrome; musculoskeletal system, e.g., arthritis and back pain; reproductive system, e.g., menstrual problems. You'll also learn how to address common problems as migraines and sinusitis. Additionally, you'll learn to apply distant healing to loved ones who are not present in the room with you. All PRANIC HEALING® courses are "experiential," which means that you learn by actually performing the techniques and exercises in class - on yourself and those around you. During class, all the principles will be explained thoroughly and you will practice the techniques exhaustively so you will be confident in your ability to produce positive results when you finish the course.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
