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.

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Talk by ## [Kyle Jenkins](https://www.linkedin.com/in/kyle-jenkins/) **Unpacking Process Anti-Patterns: Lessons from Ideation to Delivery** In the fast-paced world of software engineering, processes often shape success or sow frustration. Over the years, recurring anti-patterns have emerged well-meaning practices that unintentionally create inefficiencies, stifle innovation, or harm team dynamics. These pitfalls, though rooted in good intentions, can derail projects and undermine trust when left unchecked. Through real-world examples and two decades of industry experience, this presentation unpacks common process anti-patterns across the software lifecycle. With a focus on fostering understanding, not blame, we’ll examine how flawed workflows contribute to challenges and how reversing them can empower teams to build clarity, creativity, collaboration, and trust. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park!

Our main goal is to share the love of the Ruby and Rails ecosystems with anyone that is interested. We cater to everyone, whether a non-programmer through advanced Rubyists. * We give lectures on programming topics * We freely provide decades worth of experience * For full details of this month's meeting please visit [http://columbusrb.com](http://columbusrb.com)

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Gardening for Butterflies Talk and Walk with Butterfly Ridge Saturday, July 18, 2026 Join Chris Kline from Butterfly Ridge for a presentation on gardening for butterflies and a walking tour of Infirmary Mound Park, looking for butterflies, discussing their importance, and how to make butterfly-friendly improvements to residential landscapes. Meet at the James Bradley Center. Christopher Kline’s interest in butterflies began in 1997 when he began tagging Monarch butterflies in Indiana. Since 1997, he has tagged thousands of Monarchs, co-founded the Central Arizona Butterfly Association, and founded the Southwest Monarch Study. He has also served as the Butterfly Specialist at the Franklin Park Conservatory and Botanical Gardens in Columbus, Ohio. He now is the Director of Butterfly Ridge Butterfly Conservation Center in Rockbridge, Ohio where he and his wife have converted 21 acres of fields and forests into butterfly friendly habitats and have quintupled the butterfly population in the process. He has authored several books including A Field Guide to Tropical Butterflies of American Conservatories, Butterfly Gardening with Native Plants, Butterfly Rider, Moths of Butterfly Ridge, and the Beginner’s Guide to Mothing.
