Join us for a discussion of ***Cobalt Red: How the Blood of the Congo Powers Our Lives* by Siddharth Kara** Here's the summary: An unflinching investigation reveals the human rights abuses behind the Congo’s cobalt mining operation―and the moral implications that affect us all. Cobalt Red is the searing, first-ever exposé of the immense toll taken on the people and environment of the Democratic Republic of the Congo by cobalt mining, as told through the testimonies of the Congolese people themselves. Activist and researcher Siddharth Kara has traveled deep into cobalt territory to document the testimonies of the people living, working, and dying for cobalt. To uncover the truth about brutal mining practices, Kara investigated militia-controlled mining areas, traced the supply chain of child-mined cobalt from toxic pit to consumer-facing tech giants, and gathered shocking testimonies of people who endure immense suffering and even die mining cobalt. Cobalt is an essential component to every lithium-ion rechargeable battery made today, the batteries that power our smartphones, tablets, laptops, and electric vehicles. Roughly 75 percent of the world’s supply of cobalt is mined in the Congo, often by peasants and children in sub-human conditions. Billions of people in the world cannot conduct their daily lives without participating in a human rights and environmental catastrophe in the Congo. In this stark and crucial book, Kara argues that we must all care about what is happening in the Congo―because we are all implicated. **Let’s meet at Caboose Commons in Fairfax to enjoy some good discussion and meet new friends.**

Family Constellations is a powerful experiential process that allows you to externally map an issue you’re facing, creating a kind of three-dimensional image of the underlying dynamics. What is often felt only internally becomes visible and tangible, revealing hidden patterns that are not accessible through thinking alone. In this work, we acknowledge what is—without judgment—and begin to restore order where there has been disorder. Unconscious burdens, often carried across generations, can be seen and gently released. As these dynamics shift, the system reorganizes, allowing for a deeper sense of clarity, movement, and belonging. $65 1-5pm 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 has facilitated Family Constellation therapy for individuals and groups for more than 20 years.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
