Learn to manage stress and achieve self-growth through simple relaxation and Meditation. Heartfulness Meditation is a simple, modern, methodical approach to meditation. Rather than homing in on your breath or repeating a mantra, you simply focus inward, on your heart, to cultivate inner strength and serenity. Heartfulness meditation is gaining traction in recent years. It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

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.**

Join us for a cozy, in-person journaling session! Whether you’re new to journaling or a seasoned writer, this meetup is a great opportunity to carve out some intentional time for self-reflection, creativity, and connection with others. Event Outline: • We’ll begin with brief introductions so everyone can get to know each other. • I’ll provide a journaling prompt to help guide your writing. • Afterward, we’ll take about 10 minutes to write quietly. You can use the prompts or go wherever your thoughts take you! • Once we’re finished, we’ll come back together and share (if you feel comfortable). This is a chance to reflect on the process or share insights, but sharing is completely optional. • We'll repeat this process with another prompt or two as time allows. Bring your favorite journal or notebook, and get ready to enjoy some thoughtful, reflective time in a welcoming community. Grab a coffee or tea from the café, settle in, and let’s journal together! Feel free to come as you are—no prior experience necessary. We can’t wait to meet you!

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **"Eugenics Then and Now,”** on a dangerous movement in science and its lessons for current research, with Carlo Quintanilla, molecular biologist and health science policy analyst at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-eugenics-then-and-now](https://events.ticketleap.com/tickets/profsandpints/nv-eugenics-then-and-now) .] Global concerns about the return of eugenic thinking were reignited by Chinese scientist He Jiankui’s 2018 announcement of the first gene-edited babies, Lulu and Nana. He was quickly condemned by the scientific community and jailed for illegal medical practice, but he and others around the world continue experiments with goals echoing eugenic ambitions. As genetic technologies advance at extraordinary speed, society faces a new set of ethical questions about shaping the traits of future generations. Are we entering a new era of eugenics? If so, how should we respond? Hear such questions tackled by Carlo Quintanilla, who studied rare genetic mutations in human disease as a graduate research scientist and instructor at the University of Texas Southwestern Medical Center and now works at the intersection of genomic medicine, science, and society. Dr. Quintanilla will begin by discussing the origins and history of eugenics, tracing its development in the 19th and 20th centuries as an idea, a scientific movement, and a set of policies. He’ll examine the rise of Social Darwinism in the United Kingdom, forced sterilization programs in the United States, and the atrocities committed by the Third Reich in the name of “racial hygiene.” From there, he’ll explore how our ability to shape human health and heredity have been transformed by modern reproductive and genetic technologies such as in vitro fertilization, prenatal and embryo screening, and genome editing. You’ll learn how these tools hold enormous promise when it comes to the prevention and cure of rare and debilitating genetic conditions, yet also raise profound questions related to their potential enablement of a new, technologically driven form of eugenics. Dr. Quintanilla will then delve into the ongoing debate among scientists, bioethicists, and policymakers over what should be classified as eugenics today. He’ll highlight recent controversial uses of genetic and reproductive technologies that are pushing ethical boundaries faster than society can define them, from embryo selection for traits like IQ and height to speculative military interest in genetically enhanced soldiers. These examples raise urgent questions: Where should society draw ethical boundaries? Who gets to decide? And is the term “eugenics” still useful for guiding policy and public debate? We’ll close by examining the social, political, and regulatory forces that will determine the future, considering whether they will restrain the push toward further genetic control or accelerate it. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

What does a trojan look like when it has over 900k+ combined installs and a Forbes write-up? Exactly like a legitimate Chrome extension. This session presents a technical dissection of two Chrome extensions, each with over one million active installations — that functioned as trojans in production environments, evading detection while operating through entirely legitimate browser APIs. These were not obscure tools. They were widely trusted, actively recommended, and covered by mainstream press before their malicious behavior was fully understood. We will walk through the actual source code of both extensions, showing precisely how the malicious functionality was constructed, concealed, and executed at scale. This analysis anchors a broader examination of how modern compromises actually succeed. Drawing on aggregated real-world incident data, we identify the technique categories currently delivering the highest adversary return, and why they keep working. Spoiler: it's rarely a zero-day. It's trust. The Chrome extension deep-dive will cover: * Line-by-line source analysis of how malicious functionality was embedded within working, useful software * Which browser permission scopes were abused, and why a million users — and their IT teams — didn't see it coming * The behavioral and structural indicators that distinguish a trojan extension from a legitimate one, and how to operationalize detection around them This session closes with a practical defensive prioritization framework built around observed attacker behavior: which mitigations are measurably reducing risk in production environments, which are consuming budget without impact, and a scoring methodology your team and leadership can apply immediately. **Source material:** Primary analysis of extension source code, corroborated by reporting from Forbes and other established outlets. **What this is not:** A vendor pitch, a speculative threat narrative, or a surface-level breach retrospective. **Who should attend:** Security architects, AppSec and cloud security practitioners, blue team leads, threat hunters, browser security practitioners, and security leaders responsible for prioritizing risk and investment decisions.

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.

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
