Dodgeball is back again! If you’ve been wanting to come out, this is an easy one to join. We’ll be playing for about 1.5 to 2 hours, you do not need to bring any equipment, and no experience is needed. We use a specific set of rules and equipment to make the games run better and keep them fun for everybody, not just people who already know how to play. If it rains, the event will be canceled.

Based on the novel Roadside Picnic, it is NO picnic, but rather one of the masterpieces of world cinema. Andrei Tarkovsky's 1979 Soviet sci-fi classic, recounts the expedition of a writer and professor led by a mysterious guide called "The Stalker." to a futuristic wasteland called "The Zone." Dripping with existential dread, it continually presents strange occurrences that will have us debating the meaning of what we've just viewed right through the ending. *Stalker* (1979) can be streamed for free on HBOMax, the Criterion Channel or Kanopy. It's also available for rent on Amazon Prime and AppleTV. The Columbus Library has two copies on disc.

**Synchronicity: Coincidence or Divine Guidance?** Have you ever experienced a “coincidence” that felt too perfect to ignore? A chance encounter, repeated sign, or unexpected moment that seemed to arrive right on time? Join us at Unity of Columbus as Michelle Harcha explores the mystery of synchronicity and how these meaningful moments may be guiding us toward greater wisdom, purpose, and connection. After Sunday’s message, stay for an interactive workshop where Michelle will share practical tools inspired by Byron Katie and Marilee Adams to help us recognize and align with Divine guidance.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.
