Software Modeling

It's happening again! **WHAT:** Free Improv Drop-in. No experience needed / beginner friendly! (18+ for now; plans for a "kids and parents" drop-in are in the works) **TIME & PLACE:** Sunday 1:30pm - 3pm Delaware Library - 84 E Winter St, Delaware, OH 43015 in the Community Room **WHAT TO BRING:** Punctuality, yourself, a good attitude, and a willingness to have fun and be a bit silly and goofy around others. That's it! **WHAT THIS IS:** A time for fun and exploration. We're going to do improv warm-up exercises and play silly improv games. Think of it as "dipping your toe" into improv comedy. **WHAT THIS IS NOT:** Deep improv training with scene work; a place of judgement or worrying what others think; a place where you're expected to know what you're doing. Please mention in the comments if you're planning on attending or use the "attending/interested" function; it really helps me plan the class depending on the amount of people participating. Feel free to comment / spread the word / message me if you have any questions. Thanks! ALSO: Please don't take the amount of people marked going as the # that will be there; I post this on FB groups, Reddit, and Nextdoor, so I always have at least 3 - 6 people for games. Join us!

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.

**Presenter:** All of Us **Time:** Pizza at 6:00, Presentation Starts at 6:30pm Eastern **Location:** Theoris, 9000 Keystone Crossing, Suite 230, Indianapolis Let's have a fishbowl discussion about AI. Has it replaced you yet? Have you replaced it? Somewhere in between? How is AI impacting your career as a software engineer? Looking forward to seeing you there! ### What is a Fishbowl Discussion?

The inner circle consists of a small number of participants who actively discuss a topic, while those in the outer circle listen and observe. This format encourages participation from all members, as individuals from the outer circle can join the inner circle by taking an empty seat when they wish to contribute.](https://www.bing.com/ck/a?!&&p=00b4b265baa395dc4ad7b262d4d6e3b7b7c31b2195941076e51d2eca252c2d02JmltdHM9MTc2MjgxOTIwMA&ptn=3&ver=2&hsh=4&fclid=0e60c23d-2dbf-642d-0fd7-d4512c2b6597&psq=fishbowl+discussion&u=a1aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvRmlzaGJvd2xfKGNvbnZlcnNhdGlvbik&ntb=1)

**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.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
