THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-05-09-exploring-street-photography Street photography is very popular now more than ever because photographers have access to high quality cameras in mobile phones and smaller high resolution digital cameras. A camera’s ease of access and proliferation raises the issues of ethics and privacy in public places and the difference between a snapshot and a street photograph. This hands-on class will explore the unique aspects of the street photography genre. Michael Koren will be your guide as you create compelling photographs that go beyond the ordinary snapshot. First, you’ll learn pro level tips and techniques and discuss privacy issues associated with street photography. Then, with Michael’s guidance and direction, the group will head out to photograph near the White House in Lafayette Square. You’ll create photographs that demonstrate your personal vision while using your own gear optimized for street photography. We'll then head back to the classroom for image reviews and feedback. Topics include: -Proper techniques and settings for street photography -Pro tips and techniques for capturing compelling images -Create captivating images using anticipation, patience, composition and visualization -Hands-on image capture -Privacy and ethics concerning street photography -Image review and feedback Recommended gear: -Although any camera will do, for best results we recommend a DSLR or mirrorless camera with manual exposure controls -Lenses in the range of 28mm - 70mm (zoom or prime) -Fully charged camera battery with an optional spare -Camera instruction manual (paper or electronic) -No tripod, no flash Class size is very limited *** • Important to know **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-05-09-exploring-street-photography

Other things people would like to talk about. This will be a joint meeting with: DC 9/11 Truth [https://dc911truth.org/](https://dc911truth.org/) dc911truth Facebook page [https://www.facebook.com/groups/dc911truth/](https://www.facebook.com/groups/dc911truth/) 911 Meetup Group [https://www.meetup.com/meetup-group-kyegaoqu/](https://www.meetup.com/meetup-group-kyegaoqu/) Central Bank Digital Currencies CBDC Meetup Group [https://www.meetup.com/central-bank-digital-currencies-cbdc/](https://www.meetup.com/central-bank-digital-currencies-cbdc/) Freedom of Speech Meetup Group [https://www.meetup.com/silver-spring-freedom-of-speech-meetup-group/](https://www.meetup.com/silver-spring-freedom-of-speech-meetup-group/) One way to make it more difficult for them them to impose a digital currency on us is to use cash. Central Bank Digital Currency (CBDC) With Digital Currency they can: Have a complete government dossier on every detail of your life. Use your purchase history to maintain a detailed social credit score for every person. Provide tax breaks to corporations who hire people with admirable social credit scores. Only grant government contracts to corporations with employees with admirable social credit scores. Adjust health insurance premiums to incentivize people to develop admirable social credit scores. Connect your social credit score with a digital ID to encourage you to look at only approved web sites when surfing the internet. Viewing conspiracy web sites could lower your Social Credit Score and make it difficult to get a job. With their electronic chain around your neck, they can control where, when, how you travel, what food you are allowed to buy etc. They will love the power to only allow you to use your digital money only where they want you to shop and allow you to buy only what they prefer you to buy. Require you to have to have a license to use your money. They will call it a Digital Currency License. Require you to take any vaccine they want you to take to maintain your digital currency license. Tax you in ways we have not even imagined. Adjust your income tax rate based on your social credit score. Use AI to increase your income tax rate if you eat too many hamburgers because they will tell you eating too many hamburgers will increase global warming. This is just one example of many behaviors they might not approve of. Adjust individual prices for different individuals. They will be able to make you pay more per pound for hamburger if you purchased too much red meat during the past 30 days. Require you to buy so many pounds of soy burger for every pound of hamburger to save the planet and increase the profits for the soy burger manufacturers. Turn off the digital money of people they consider to be spreading misinformation. Turn off the digital money of people they consider to be dangerous conspiracy theorists. Turn off your money at 8 PM if they want a curfew at 8 PM Turn off your money in another state if they do not want you to drive to another state without permission. Turn off your money when buying guns or ammo if they do not want you to buy guns or ammo. Turn off your digital money more than three miles away from your home if they want you to stay within three miles of your home during the next epidemic. Etc. etc. etc. From the standpoint of the government, one beauty of digital money is that your money is one “state emergency” away from being the government’s money. All they have to do is to take your digital money out of your Central Bank Digital Account for the “good of all”. It is not as easy for them to do this with physical cash, gold, stocks, or silver etc. Anything they **can** do, they will do. The essence of slavery is control. Digital Currency will enable them to make you, their slave. (in a global digital concentration camp). .

Shall we draw at Quill & Crumb, the cafe in the Folger's Great Hall? It's a gorgeous setting where we'll undoubtedly find many interesting things to draw. From the website: "Quill & Crumb is located in the Folger’s historic Great Hall, which was originally designed by architect Paul Philippe Cret to resemble a gallery within a 16th-century English home. The Great Hall features strapwork plaster ceiling, oak-paneled walls, and intricately designed terracotta floors." Look forward to meeting you there!

Join me for a small, mindful photography walk in nature. (**NOTE Time is 9:00 AM EST(Meetup is having technical Issue))** This is a slow, intentional gathering — not focused on fitness or perfect photography — but on simply pausing, observing, and being present. We’ll walk at a gentle pace, with moments of quiet, and a few light prompts to help you notice details you might normally miss. 📷 You don’t need any photography experience — a phone camera is enough. This is also not a business networking event. It’s a calm space to connect with nature and, if it feels natural, with like-minded people. 🌿 What to expect: • A slow-paced, relaxed walk • Moments of silence and observation • Simple reflection prompts 📍 Location: [ Red Trabue Nature Preserve] ⏱ Duration: \~60 minutes This is a small, initial gathering as I begin creating this space through WellGratiVibes — a blend of mindfulness, nature, and quiet connection. If this resonates with you, you’re welcome to join.

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?

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!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
