**Moved from original date (requested by several members) due to the heat wave!** Most businesses know they have repetitive tasks, manual workflows, and administrative bottlenecks - but few know where to start when it comes to automation. In this practical introductory session, we'll explore how modern businesses are using AI, workflow automation, and intelligent agents to streamline operations, reduce costs, and free up teams to focus on higher-value work. You'll learn how to identify the best automation opportunities within your organisation, map existing processes, and build a roadmap for implementing automation without disrupting your business. We'll also demonstrate real-world examples of automated sales, marketing, customer service, finance, and operational workflows that are delivering measurable results today. Whether you're a business owner, manager, operations leader, or technology professional, this session will provide a clear framework for turning automation from a buzzword into a competitive advantage. ### What You'll Learn * Where automation delivers the biggest business impact * How to identify and prioritise processes for automation * The difference between traditional automation, AI, and intelligent automation * Common automation mistakes and how to avoid them * Real-world case studies and live demonstrations * A practical roadmap for getting started immediately ### Who Should Attend Business owners, founders, directors, operations leaders, department heads, and anyone interested in making their organisation more efficient through intelligent automation.

AI assistants are getting more capable. The question is how we build effective workflows around them.

In this event, we will discuss about a science or philosophy book chosen by London Science and Philosophy Book Club. The attendees will be divided into groups and each of them will focus on a chapter in the book. This month we will discuss about a fascinating book called Supersense: From Superstition to Religion by Bruce Hood. If you haven't read the book, it's no problem. I will bring you up to speed with the discussion materials. We will meet in a nice lounge area at 6 p.m for introductions. Please come on time so you will not miss out on valuable discussion midway. If you end up in the waitlist, feel free to show up. Book Description: Why is it that Tony Blair always wore the same pair of shoes when answering Prime Minister's Questions? That John McEnroe notoriously refused to step on the white lines of a tennis court between points? And that President-elect Barack Obama played a game of basketball the morning of his victory in the Iowa primary, and continued the tradition the day of every following primary? Superstitious habits are common. Do you ever cross your fingers, knock on wood, avoid walking under ladders, or step around black cats? Sentimental value often supersedes material worth. If someone offered to replace your childhood teddy bear or wedding ring with a brand new, exact replica, would you do it? How about £20 for trying on a jumper owned by Fred West? Where do such feelings come from and why do most of us have them? Humans are born with brains designed to make sense of the world and that need for an explanation can lead to beliefs that go beyond reason. To be true they would have to be supernatural. With scientific education we learn that such beliefs are irrational but at an intuitive level they can be resistant to reason or lie dormant in otherwise sensible adults. It now seems unlikely that any effort to get rid of supernatural beliefs or superstitious behaviours will be completely successful. This is not all bad news - such beliefs are a useful glue that binds us together as a society. Combining brilliant insight with witty example Hood weaves a page-turning account of our 'supersense' that navigates a path through brain science, child development, popular culture, mental illness and the paranormal. After reading SuperSense, you will realize why you are not as reasonable as you might like to think - and why that might be no bad thing. Agenda: 6 p.m to 7 p.m: Introduction and Socializing 7 p.m to 9:30 p.m: Book Discussion 9:30 p.m to late night: Drinks, Dinner or Feel free to go home

Your survival depends on knowing who you can rely on. But how can you tell who your real friends are? How can you determine if a person will help make a joint venture successful? Is there a way to predict behavior? Yes. There are fundamental elements to human behavior. When you know them you have insight into your fellow man, and just by observing how people act, you will know *everything* about them. #### On this lecture you will learn: * The important role of trust in human relationships. * The Hubbard Chart of Human Evaluation—the tool to know true character and predict what people will do. * How to evaluate others accurately and guarantee a more certain future for yourself and those you care about. With the knowledge you learn on this course, you will have tools to know who you can trust and who you can depend on. *“Trustworthiness is a highly esteemed commodity. When one has it, one is considered valuable. When one has lost it, one may be considered worthless.”* *—L. Ron Hubbard*

**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.

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.

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.
