Smart Contracts

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

**Caller: Kim Thompson** **Band: Full Moon Country Dance Orchestra** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.

The market changed—and most investors are still operating like it didn't. Deals that used to work don't. Buyers want different things. And a lot of what's being taught right now is outdated or just wrong. And, since 2011, it's been our job to make sure that our members are armed with the most up-to-date, real-world strategies for building wealth in Central Ohio real estate… …so our mission with this meeting (and every meeting) is to give you the no-hype, warts-and-all info you need to succeed. First, Wholesaling 101—a clear, real-world look at how wholesaling actually works today, what to pay, and how to stay out of trouble. Then, Creative Deal Autopsies—real investors breaking down real deals with real numbers, real conversations, and real outcomes. You'll also get the chance to put the presenters in the hot seat and ask any and every question you have about how they did their deals. You'll learn: 1. What wholesaling actually is 2. How to calculate real offers 3. Where deals are coming from now 4. What buyers want 5. How creative deals are structured 6. What contracts and terms are used 7. What can go wrong—and how to avoid it **Agenda:** 5:00–6:00: Free Light Dinner and Networking 6:00: Earlybird Meeting – Wholesaling 101 7:00: Buy-Sell-Trade (members only) 7:30: Creative Deal Autopsies Members: Free First-time guests: Free Non-members: $35 (or join for $30 instead) Remember, to actually reserve your seat, you have to go **[HERE](https://www.coreerocks.com/Events.aspx?ID=IN-PERSON-in-Columbus-Creative-Deal-Autopsies-Wholesaling-101-14-4-7-2026)** and register on our website!

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

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.
