**\*\*\*\*GO TO EVENTBRITE FOR LINK TO MEETING:\*\*\*\*** [Men's Virtual Chapter, Recovering from Religion Support Group Tickets, Multiple Dates | Eventbrite](https://www.eventbrite.com/e/mens-virtual-chapter-recovering-from-religion-support-group-tickets-722315403817?aff=oddtdtcreator) This is an RfR-wide event, not tied to any particular local chapter. \*NOTE: This meeting is solely for individuals who identify as male. The Recovering from Religion MEN'S Chapter Online Support Group will meet the 1st Saturday of each month @ 10am Central Time (USA), 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 peer 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. These groups are free, small group style meetings. No professional therapist is present, group leaders are volunteers trained in peer support. You are not required to give your real name or show your face on camera. You will be invited, but not required to talk about yourself and your experiences. Be aware that trolls sometimes appear. Your group leader will make every effort to eject anyone behaving badly as quickly as possible. Extra Support: RfR has an immense database of well-curated digital resources collected on all topics related to doubt, non-belief, and transition out of religion. [www.recoveringfromreligion.org/resources](http://www.recoveringfromreligion.org/resources) If you find you need to talk with someone before the meeting date, RfR has a Helpline with phone and online chat for that express purpose. [www.Recoveringfromreligion.org](http://www.recoveringfromreligion.org/) . If you’re seeking 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.](http://www.seculartherapy.org./)

To all locals, expats, and visitors in Tallinn, welcome! My wife and I are delighted to invite you to study the Word of God with us every Friday at 5:30 p.m. in a casual setting, accompanied by coffee and tea. We believe the Bible is entirely true, and we strive to live by its teachings. We also believe that the love of God is so powerful that it can touch hearts and heal what's broken in all of us. Let's study Christianity together to help you find answers to questions like: * What is the meaning of life? * How do I deal with difficult situations? * Who is God, and what is the Trinity? * How can Jesus Christ help me? * How can I forgive and treat others with love? Please join us or reach out if you have any questions! The meetups are in English.

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development

( this meetup was rescheduled from 1-27 due to the weather conditions) **NEW LOCATION - THE DAILY GROWLER -** **2812 Fishinger Rd, Upper Arlington, OH 43221** Over the years, we’ve heard two requests constantly: 1. A place that was quieter and possibly private. 2. “I wish they accepted Bitcoin.” We’ve finally found a solution to these requests with The Daily Growler. We’ll have access to their private room, and you’ll be able to pay your tab with Bitcoin. Join us for a fun and relaxed social event! Enjoy delicious food and drinks as we chat about the latest news in the Bitcoin world. Everyone is welcome, whether you're looking for guidance, have questions, or just want to meet like-minded people. These social evenings are a great opportunity to make new friends and enhance your experience at the larger events throughout the year. We look forward to seeing you there! PSA: If the attendee RSVP seems low, keep in mind that most of our attendees come from X and not [meetup.com.](http://meetup.com./) You are welcome to come and become a part of our online community.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

Join members of the local UX and Digital Design community for a casual monthly breakfast. There _might_ be a little snow, but there _will_ be effectively infinite serve-yourself coffee, so it evens out if you ask me. Just a reminder, while the other locations are great too, we’re at the Lane Ave one this time.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier! Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is brought to you by the Dianetics and Scientology life improvement center.

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)
