AI Freedom Alliance - Inaugural Summit
AI Freedom Alliance - Inaugural Summit
**\*\*\*\* More details and sign up at: https://aifalliance.org/summit-2026/ \*\*\*\*** **What is AI Freedom Alliance?** AI Freedom Alliance promotes the responsible growth of AI guided by practical, commonsense ethics. Our nonprofit is built by professionals from a wide range of industries and is made up entirely of small- and mediumbusiness representatives—never large tech companies. We provide a counterbalance to big corporate influence, focusing instead on how AI can benefit businesses and the world at large. **What’s Happening?** ***The inaugural AI Freedom Alliance Summit.*** This full-day event will explore how we can ensure AI is adopted responsibly through shared ethical standards that empower humanity. The summit will feature interactive and educational sessions led by thought leaders, technologists, policymakers, and advocates who are passionate about making AI fair, transparent, and beneficial for everyone. **Why Attend?** Learn about the legal and technical challenges with implementing AI solutions within your organization. Build better solutions while protecting your organization from legal and compliance risks. And learn how to think strategically about AI as a differentiation tool for your business. This summit is highly recommended for C-Suite leaders to learn as well as interact with each other and our sponsors.

CMG Gives Back - March: Serve Brunch at FAITH MISSION GRANT KITCHEN!
Join us as we get together to get together to help those in need at this CMG Gives Back event! For this event, we’ll help prepare food, serve meals, assist residents, wash dishes and clean surfaces at Fath Mission – Grant Kitchen. We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “Create a better world” by helping serve those in need. Here are complete details and our plan for this event: FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. Our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces. PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:15am and wear closed-toe shoes and long pants. LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1, indicated in the attached map. On-site and street parking are available in the surrounding area. Below are some links / attachments with additional info/details: \* LSS Volunteer Guidelines: Uploaded to photos. \* Parking Map Info: Uploaded to photos. \* LSS Faith Mission Orientation Video: https://www.youtube.com/watch?v=Bp46_6ay6iA \* Link with Additional Details / Info: https://lss.vomo.org/opportunity/faith-mission-grant-kitchen-2025 IMPORTANT REMINDER: Our group will be providing the all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please update your RSVP no later than one week prior to the event. With very few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. THANK YOU: This CMG Gives Back event provides an opportunity for YOU to get involved in helping others! Benefits go well beyond the help we give to others. Volunteering provides a wide range of personal benefits, including positive effects on mental and physical health, reduced stress/depression/anxiety, increased happiness and improved purpose, life-satisfaction and personal well-being! Plus, the opportunity to get involved, connect with others and help those in need. PARTNER AGENCY: This event is hosted by Lutheran Social Services (LSS), which serves thousands of people in need each day in 27 Ohio counties by addressing the four core societal issues of food, shelter, safety and healing. LSS offers food through the LSS Food Pantries, housing and supportive services through LSS Faith Mission and LSS Faith Mission of Fairfield County homeless shelters, domestic violence services through LSS CHOICES for Victims of Domestic Violence, senior living and health care, affordable housing communities, and other services that uplift families and strengthen communities. Look forward to seeing you there, Dan
Sunday Board Games at Land-Grant Brewing
Sunday Board Games at Land-Grant Brewing
We'll play board games at the [Land-Grant Brewing Company](https://landgrantbrewing.com/). The brewery has multiple [food trucks](https://landgrantbrewing.com/food/) on Sundays, including [Ray Ray's Hog Pit](https://rayrayshogpit.com/franklinton), [Buck City Sammies](https://www.buckcitysammies.com/menu), and [Hai Poké](https://www.haipokefoodtruck.com/). The brewery also has (passable) drip coffee, free water, and Jeni's ice cream. You can also walk over to the [Land Grant Extension](https://callinyourbluffcoffee.com/) for "real" coffee. (You may have to stand in line, though. The Extension is popular.) You can come late or leave early. Please just sign up so I know to expect you. **Notes on Parking** * You'll (probably) have to park on the street, but street parking is free on Sundays. * There are [parking garages](https://landgrantbrewing.com/parking/) a little farther away if you want. These are obviously not free, though. * There is a [lot next door](https://www.google.com/maps/place/39%C2%B057'26.0%22N+83%C2%B000'40.9%22W/@39.957211,-83.0119921,19z/data=!3m1!4b1!4m12!1m7!3m6!1s0x88388f3efd89238b:0xc139207386232411!2sLand-Grant+Brewing+Company!8m2!3d39.9577613!4d-83.011426!16s%2Fg%2F1pzt7t9df!3m3!8m2!3d39.957211!4d-83.011347?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) to the brewery that you're allowed to park in, but it is not free. I've never parked there, so I don't know anything about rates. (I'm told though that if you eat at Milo's Deli next door to this lot that Milo's will stamp your parking so it's free.) * You're going to see odd signs on [Lucas St](https://www.google.com/maps/place/39%C2%B057'26.1%22N+83%C2%B000'40.3%22W/@39.957256,-83.0124134,19z/data=!3m1!4b1!4m10!1m5!3m4!2zMznCsDU3JzI4LjgiTiA4M8KwMDAnNDEuNSJX!8m2!3d39.957993!4d-83.011536!3m3!8m2!3d39.957256!4d-83.011197?entry=ttu&g_ep=EgoyMDI2MDEyMS4wIKXMDSoKLDEwMDc5MjA3MUgBUAM%3D) (saying it's a "private street") that will lead you to believe you're not allowed to park there, but you actually are. * Columbus parking cops literally do not work on Sundays. This means that, even if you're driving a non-EV, you can park in the EV spots near the brewery. **Games** I do bring many games, but please bring some of your own as well.

Spec-Driven Development with GitHub Spec-Kit - Barret Blake
Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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

Humanist Program: Fighting the Efforts to Insert Religion into Public Education
Humanist Program: Fighting the Efforts to Insert Religion into Public Education
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon
