In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.

Shut Up & Write! Kingsdale Shopping Center
Greetings writers! Come down and join your fellow wordsmiths for one hour of uninterrupted writing time in the upper level of the Market District Supermarket in Upper Arlington.
The main entrance of the shopping center opens onto stairs/elevator leading up to the 2nd floor cafe section where we will have a table displaying a sign with the Shut Up & Write logo.
Writing is largely a solitary craft. Practicing with others in a community setting may be the thing you need to fire your own routine.
We’ll meet on Wednesday evenings, starting the clock at 6:30, following a brief period of introductions. This is solid writing time and all inclusive. Any project is acceptable, be it fiction, non -fiction, work or homework assignment. All is welcome and will remain private to you.
The market boasts a Starbucks, a full service bar and various affordable food options. Parking is plentiful, free Wifi is provided as well as outlets for charging your devices, though they are somewhat limited, so plan accordingly.
Show up as early as you like, or stay late. This group tends to socialize some, both before and after the alloted time, but this is not mandatory to you. Feel free to come and go as you please and late arrivals are welcome.
The cafe may be noisy on occasion so headphones/ earbuds are reccommended as you see fit.
Please try to RSVP if possible so that we may grab enough seats for all—the venue can be busy at times.
Feel free to message me privately wth any questions and/ or concerns you may have.
Happy writing!

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs.
This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context.
We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing.

Omnipresent Atheists Weekly Meetup (2nd Tues)
Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room.
This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us.
COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.

Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.
Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA). AoC members are invited to join this OA meetup and/or OA Facebook group ( https://www.facebook.com/groups/omnipresentatheists/ ) but are free to continue conversations on the AoC Facebook group ( https://www.facebook.com/groups/columbusatheists/ ). AoC was founded in 2012 as a networking, social group for Central Ohio area humanists, skeptics, atheists, agnostics, nonbelievers, freethinkers, and the curious. It was a member of Columbus CoR and held weekly meetings, mostly on Fridays, for several years but then operated as an online only group for some time. In November 2018, Omnipresent Atheists (OA), a group that routinely meets on Tuesdays, invited AoC to merge.
Omnipresent Atheists is a member of the Columbus Coalition of Reason (ColumbusCoR.org). Omnipresent Atheists is a member of the Columbus Coalition of Reason ( http://www.ColumbusCoR.org ). Omnipresent Atheists endorses the mission of the Secular Coalition for America ( http://secular.org ).
CBusData - Practical AI for Power BI Developers
Practical AI for Power BI Developers
A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective.
This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly.
Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

LLM Showdown: ChatGPT vs Claude vs Gemini vs Local Models
Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability.
You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
