### **What’s Unhappy Hour Breathwork, you ask? It’s our conscious breathing session to embrace our discomfort, sip some soothing tea, and dive deep into the beautiful chaos that is our childhood trauma, daddy issues, mommy issues, work stress, and those oh-so-fun failed relationships. Think of it as a cozy gathering where we can unpack our baggage together, all while sharing a laugh or two (or maybe a few tears).** Let’s be real life isn’t always sunshine and rainbows, and that’s perfectly okay.**We will give ourselves permission to be gloriously miserable for a full 90 minutes to** release the weight of our struggles. By using our own conscious breathing we’ll transform our experiences into something powerful and healing. Session will end with a soothing sound bath. Tea will be provided! Mark your calendars for this weekly dose of camaraderie and self-discovery. **What is Breathwork?** Breathwork falls under an umbrella term with many different marketing names and techniques. For this session we will be focusing in one technique while laying down on our back. This is NOT your typical relaxing breathing and it DOES NOT INVOLVE ANY YOGA movement. Breathwork takes us deep into the subconscious mind to make necessary changes and improve our lives by releasing emotional baggage and healing emotional wounds. When we tap into deep states of consciousness emotional release may take the shape of crying, laughing, even screaming. Many people like to call it years of therapy in one single session. It is very common to experience moments of clarity, bliss and many Aha moments during this session. Each person will experience something different with every session. All you need is an open mind and your own breathing to achieve results with no prior experience. Please note breathwork cautions before booking. **What you may experience during this session:** -Deep healing of emotional wounds, grief and traumas -Ability to connect to your higher self, Ancestors and the divine -Release anxiety -Improve emotional balance -Increased feelings of joy, happiness, and inner peace -Ability to create self-love and improve relationships **What to bring:** -Your own water bottle -A pen and notebook -A Yoga mat (or use one at the studio) -A blanket ( or use one at the studio) -Eye mask (if you have one) -Comfortable clothes to breathe and lay down **About Jenny Perez Curandera:** Jenny is a Curandera Shamanic Healer born into the Curanderismo Tradition.

**GO TO OUR WEBSITE FOR LINK TO MEETING:** https://www.recoveringfromreligion.org/sg-calendar This is an RfR-wide event, not tied to any particular local chapter. \*NOTE: This meeting is solely for individuals who identify as female, non-binary and gender-fluid. The Recovering from Religion WOMEN'S chapter support group [Europe-based time zones] will meet the 2nd Tuesday of each month @ 6pm local time UK, unless the date falls on a holiday. Attendees are welcome to share, and may also decide to remain anonymous if they so choose. The primary focus of a Recovering From Religion support group is to provide ongoing and personal support to individuals as they let go of their religious beliefs. This transitional period is an ongoing process that can result in a range of emotions, as well as a ripple effect of consequences throughout an individual’s life. As such, the support meetings are safe and anonymous places to express these doubts, fears, and experiences without biased feedback or proselytizing. We are here to help each other through this journey. There is no cost to attend this support group but, if you feel so inclined, donations can be made at www.recoveringfromreligion.org/donate If you find you need to talk with someone before the next support meeting, RfR has a hotline and online chat for that express purpose. Go to www.recoveringfromreligion.org and click on the green chat bubble in the lower left corner of the site to chat online. If you are in need of professional help, we can offer the Secular Therapy Project to provide options to connect with a professional therapist. All therapists have been thoroughly vetted by our organization and offer only evidence-based and non-religious treatment. Connect with them at www.seculartherapy.org. Like what RfR does? Why not volunteer! There are quite a few options. Head over to www.recoveringfromreligion.org/volunteer for more info.

Healthcare organizations are increasingly using cloud-based real-world evidence (RWE) platforms to power clinical research, population health analytics, and AI-driven insights. However, building these systems on AWS introduces complex governance challenges around privacy, compliance, and multi-institution collaboration. This session explores how to architect data governance into healthcare analytics platforms on AWS, focusing on practical design patterns rather than policy theory. We examine how ethical data stewardship principles such as consent, accountability, and responsible data use, can be implemented using cloud-native controls and services. The presentation walks through key architectural considerations for secure RWE platforms on AWS, including role-based access control, auditability, data minimization, and encryption, and how these capabilities support compliance requirements such as HIPAA and GDPR. Attendees will learn how federated, multi-account AWS architectures enable collaboration across institutions while preserving local data ownership and control. We will also discuss privacy-preserving analytics patterns on AWS, including approaches that support federated learning, differential privacy, and secure computation to enable AI-driven insights without exposing raw patient data. Practical implementation trade-offs such as performance, scalability, and operational complexity will be highlighted using real-world platform scenarios. Attendees will leave with actionable AWS architecture patterns and governance strategies for building secure, compliant, and scalable real-world evidence platforms that unlock innovation while maintaining patient trust.

GM Jason will run an Ultraviolet Grasslands session. Stay with me, here: what would happen if we mashed up Oregon Trail with Dying Earth with Mad Max? Well, UVG answers that question (that nobody ever asked) with this heavy metal psychedelic fantascience pointcrawl game. Please the horned catlords by hitching your lime green fox-ocerous pony to your wagon and heading west to see if you can’t trade all this vampire wine for some profit! None of those words will make any more sense to you after playing, probably, but we’ll have an amazing time exploring! This will be way more about the joy of exploration, the tedium of travel, and the thrill of commerce than it will be about battle. If that sounds refreshing, come try something new with us! This might be the first session in a mini-campaign, so we will start with rolling up new characters! New players welcome! No prep needed! **Where**: Your Hobby Place in Old Town Alexandria Looking for a place to play in-person RPGs and make new friends? Burnt out on internet D&D?

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!

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
