Does it feel like the world is ending? Stop doomscrolling and try some vigorous outdoor activity! We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, January 18 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

Are you wanting to get unstuck from unconscious blocks that are sabotaging your life? Are you ready to see your future clearly and follow your heart's desire? Family Constellation is soulful work that was developed by Bert Hellinger in Germany. Use it to become empowered to get the health, wealth, love, and for issues proving difficult to treat with traditional therapy. Learn highly effective techniques to liberate yourself from patterns and reawaken your vitality, confidence, and joy! Move forward in life with renewed purpose. A constellation provides a “living map” of key impactful issues and leads you towards the restoration of balance, order, harmony and healing. Each of us, whether participant or observer, taps into information that exists and benefits from the knowledge. The real power is knowing where we came from, where we belong and where we want to go. You will also learn how to identify the unconscious loyalties, unresolved traumas, and hidden dynamics that contribute to patterns of illness, complaint, and disappointment. This energy field therapy provides assistance to make peace with the past, freeing us to reside in the present, and to generate a new fulfilling future. BIOGRAPHY 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 facilitates Family Constellation therapy for individuals and groups.

Higher Grounds – Del Ray is part of a growing network of gatherings where we create space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room. There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique. MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech. Come ready to share, reflect, and connect with others in Del Ray who are also seeking deeper conversations. **Suggested Questions: Life Stages & Transitions** 1.

Improv workshop at Library. We will teach basics of Improvisation and rules before each game. Experienced and newbies alike are welcome to attend/participate. If you don't want to perform this time around, feel free to come enjoy the workshop and relax. If you need to cancel, please change your status to "will not attend."

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Optional topic for this meet up: Is life a dream? Is life a simulation? Dreams feel real while they last. Could life work the same way? How do we know we’re awake, and what follows if we can’t be sure? Let’s kick that around over a around of drinks: • What makes something feel real: continuity, shared evidence, or meaning? • How do we know we're not in a simulation? • How would you tell you’re awake (reality checks, memory, other people)? • If life is dreamlike, what becomes of free will and responsibility? • Is identity a story we keep telling—who’s the narrator? • Are we author, actor, or audience in our dreams and how would you tell? • Does art/film reveal reality or replace it? No lectures. Friendly crowd. Drop in for one drink and stay if it’s fun.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group × DevOps Columbus** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS, Columbus HashiCorp User Group, and DevOps Columbus meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/azure-cbus-2026/
