Hi and welcome to our next Socrates Café philosophy meetup! Do you have a hunger for deeper understanding of yourself and the world? Do you value deep, honest and respectful dialogue? If yes, then this meetup will be very interesting for you. • WHAT IS A MEETUP ABOUT? We ask, answer and discuss questions and ideas to stimulate critical thinking and to widen our perspectives with new concepts and thoughts. The main purpose of these meetups is to enrich ourselves with the perspectives of others, not to convince others about our own perspectives. Our meetups are about our own philosophies of life and not necessarily what the great philosophers and academics have said or written. It is not a debating club or a platform for proselytizing. Instead, we place the emphasis on questioning, open mindedness and challenging our own assumptions while listening to and respecting the views shared by others. A Socrates Café meetup is considered a success when participants leave a discussion with many more questions than they had at the beginning. • WHAT TOPIC IS DISCUSSED AT THE MEETUP? Participants suggest topics at the beginning of each meeting. We then vote and choose that event's most popular topic for discussion. No academic training in philosophy necessary; just enthusiasm for exchanging ideas and points of view. Some examples of subjects chosen on previous meetups: * What ideals are worth dying for? * Why are we never satisfied? * Why is it that human beings know that the society is going wrong, leaders are well informed about it and things continue as is? * Is identity necessary? * How can it be that people in democratic societies are so obsessed with power? (Desire to be different, better, stronger than others) * What is friendship? • WHO PARTICIPATES AT THIS MEETUP? Anybody is more than welcome to join our meetups. Our events gather people from different backgrounds, different cultures, while no philosophical background is mandatory. Our usual participants are people that have a hunger for deeper understanding of themselves and the world. People that value deep, honest and respectful dialogue. The inspiration for Socrates Cafe originates with the book of the same name, written by the philosopher Christopher Phillips. (Socrates Cafe: A Fresh Taste of Philosophy, 2002). Phillips felt that the Socratic method of dialogue and discussion should be practiced not just in academic settings, but among everyday people interested in examining deep questions together. Hundreds of Socrates Cafe groups now exist around the world.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

Join us on for a Discount Tuesday event to see the fun romantic-comedy YOU, ME & TUSCANY! The film stars Halle Bailey and Regé-Jean Page and follows a woman who crashes at an empty Italian villa, posing as the owner's fiancée. Here’s a description, trailer and plan for this event: DESCRIPTION: A free-spirited, young cook makes a brash decision to become a squatter in an abandoned Tuscan villa owned by a man she barely knows, leading to a whole new world of adventure, lies, and love when she meets the homeowner's cousin. The charming, Destination Italy, feel-good rom-com stars Halle Bailey and Regé-Jean Page.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
