Data Computing

Do **NOT** sign up to this one and sign-up at https://www.meetup.com/columbusjs/events/313386504/ ======================================= A hand tracker gives you joints, not a gesture. This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

Evolve is all about creating an Authentic Community, Deeper Connections, and Confident Growth. We are a group of entrepreneurial women who connect personally and professionally. We welcome every guest to experience our authentic community with no cliques and no judgment. Come as you are! There's a seat waiting for you. Elevate is an action-oriented connection experience designed to help women entrepreneurs move beyond surface-level networking and into meaningful growth, collaboration, and courageous action. Each session centers around a focused business or personal development topic, followed by intentional breakout discussions that encourage deeper conversations, real relationship-building, and practical next steps. Unlike traditional networking events, Elevate is designed to create momentum. Women are encouraged not only to share ideas, but to actively support one another through accountability, collaboration, brainstorming, and action-based growth. Every meeting is an opportunity to build authentic connections, gain fresh perspective, and leave with a clear action step to implement before the next session. This is a space where women rise together — not through competition or hustle culture, but through encouragement, courage, consistency, and intentional community. \*\*Evolve Women's Collective is a membership based professional women's group.

**Talk Description** How do you build a card game in Python without the logic turning into spaghetti? We'll use a working Euchre app to walk through a practical pattern: creating card and game state data structures, using a pure Python rules engine, and finally creating a pygame UI. Includes a live demo. Come learn a little about Euchre and pick up some skills and tricks to build your next game or app. No Euchre or pygame experience needed. All skill levels welcome. Laptops optional. **Agenda:** 7:00pm - Opening announcements 7:10pm - Main Topic - Building a Card Game with pygame 7:50pm - Q&A

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!

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

**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.

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: In this session, we will explore the concept of hyperdimensional computing (HDC), a brain-inspired method of computing. We'll begin by talking about neurons and the brain. Through simple Python examples we’ll dive into HDC and answer: What it is? How does it work? And, how does it learn? We will review how other researchers have applied HDC and demonstrate how it can be used for solving cybersecurity tasks. Where deep learning fails, HDC excels. No supercomputer? No problem. HDC offers interpretability, low energy requirements, robustness to errors, online learning, on-device learning, and more. By pushing the difficult calculations into the embedding process, learning becomes a cinch. By the end of this talk, attendees will have everything they need to teach their own hyperdimensional computing models. We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com
