The topic for February is "Transitions" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!

**Abstract:** The Advanced Photon Source (APS) is an X-ray light source at Argonne National Laboratory where researchers perform imaging, diffraction and spectroscopy experiments at 68 specialized beamlines. APS recently completed a major upgrade that made it the brightest synchrotron in the world and upgraded many of the beamlines to take advantage of the dramatically brighter, more coherent beam. These new capabilities are increasing the facility’s raw data production from <10 PB/year before the upgrade to >100 PB/year once all instruments are back online. To meet this data challenge, the APS Beamline Data Pipeline project team is partnering with beamline staff to develop and deploy science data pipelines that use a common set of open-source software tools (many written in Python) to link instruments with the Polaris supercomputer at the Argonne Leadership Computing Facility (ALCF) for data processing. This talk will describe the APS data systems, our file-based and streaming pipeline templates, and some of the open-source software we use to extract scientific insights from beamline data. **Audience Takeaway:** Open source Python data acquisition and analysis tools are ubiquitous at the APS. Many of the packages that are mentioned can be found at [https://github.com/AdvancedPhotonSource](https://github.com/AdvancedPhotonSource). This is a *hybrid* event.

We are recruiting new group leaders for virtual men's groups! Our primary groups are outdoor movement groups, but we are launching virtual groups for the state of Ohio and beyond and the groups will move outside in the spring, creating room for men's groups, women's groups and coed groups all over the country. Read below to learn about our groups and click the links at the bottom to apply. ### **What is an Outdoor Empowerment Group?** Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being. Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment. ## **Why Join?** * **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance. * **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space. * **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection. ## **The Ideal Group Leader** The ideal group leader * Has a born-in passion for mental health, movement, connecting with nature and building community. * Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us. * Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind. * An ability to manage groups with high emotional intelligence and desire for human connection. * An ability to self-motivate and market/promote their group on Facebook and other social platforms. * Nature informed therapy or clinical therapists/psychologists a plus. ## **Our Impact**  Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported: * A noticeable improvement in mental clarity and emotional well-being. * An increase in social connection and a sense of belonging. * Said they would return again. We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself. ### **Why Our Groups are Donation-Based** Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission! Every contribution helps us: * **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization. * **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year.

Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
