**New Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

Builders, creators, architects, admins, consultants - come one, come all. This one's for you. We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! Tonight's a special one; this is "Long form" night! Most nights here at Improv Meetup, we play "short form" games, where the host has established rules that the players must adhere to. These scenes frequently do not tell a connected story and are focused on following those rules; games such as "Alphabet Game" where every next sentence needs to start with the next letter of the alphabet, or "Interrogation" where it's a guessing game. Tonight is focused on "long form", where we will see groups of people come up and do a sort of improvised play. There may be rules to the structure itself to adhere to, or it may be more free form, but doing this allows players to establish a shared world, and to establish characters and callbacks. While your average game may last 2-3 minutes, a long form set may last longer, and have 4+ people involved. This may be a more complicated night, but we will make sure you feel supported to try this out. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

We will meet next to the restrooms at the [Big Meadows Picnic Area](https://www.metroparks.net/wp-content/uploads/2022/06/HBK_Web_1980.png). They're all the way at the back of the park, and they can be found at coordinates [40°09'06.6"N 83°02'30.2"W](https://www.google.com/maps/place/40%C2%B009'06.6%22N+83%C2%B002'30.2%22W/@40.151828,-83.0423587,214m/data=!3m2!1e3!4b1!4m10!1m5!3m4!2zNDDCsDA5JzA4LjAiTiA4M8KwMDEnNDUuMSJX!8m2!3d40.1522222!4d-83.0291944!3m3!8m2!3d40.151827!4d-83.041715?entry=ttu&g_ep=EgoyMDI0MTIwNC4wIKXMDSoASAFQAw%3D%3D) (near the playground and the zip line). We'll hike about 5 miles at [Highbanks Metro Park](https://www.metroparks.net/parks-and-trails/highbanks/) on the Dripping Rock and Overlook Trails. Afterward, we'll head over to [Olentangy River Brewing](https://www.olentangybrew.com/) for drinks, coffee, or food (their Sunday [food truck](https://www.olentangybrew.com/eventsandfood) is Venezuelan and always gets good reviews). The actual address of the brewery is [303 Green Meadows Dr S, 43035](https://www.google.com/maps/place/303+Green+Meadows+Dr+S,+Lewis+Center,+OH+43035/@40.1551938,-83.0144045,17.25z/data=!4m6!3m5!1s0x8838f395cef06c97:0xe407de61b3e30069!8m2!3d40.1551765!4d-83.0124352!16s%2Fg%2F11c26jc7j9?entry=ttu). If you can't make the hike, we should be there by noon. **How to find our starting point in Big Meadows:** If you are new to Highbanks, the Big Meadows picnic area is 1.5 miles into the park just after you turn into the park off of U.S. Route 23. That is, after you enter the park, drive a mile and a half into the park. You will come to a crosswalk with a yield sign in the middle of it (this is not to be confused with the first such crosswalk you come to just in front of the Nature Center, which you arrive at maybe a quarter of a mile into the park). Just after this second crosswalk, make a left. Then make another almost immediate left into the parking lot on your left. There you will see the jungle gym and the kiddie zip line to your left. I will be just in front of the restrooms just a bit further down from the jungle gym and picnic shelter; the restroom building will also be on your left.

Columbus Code & Coffee is excited to partner with GiveBackHack to put on the Healthtech Impact Sprint from 3/28-3/29 at Rev1 at The Peninsula! RSVP here using promo code CODEANDCOFFEE: https://luma.com/tk2jdrxk This is a health-specific version of GBH’s traditional weekend event. Participants pitch, research, and prototype health-focused projects for a chance to earn to $5K in funding from The Columbus Foundation and IGS Energy. On Saturday, folks will pitch their idea, form teams, and build. On Sunday, they’ll finalize their pitches before showcasing their work to the community and judges. # ​Schedule ​**Sat, Mar 28** * ​​9a: Doors open & breakfast * ​9:30a: Kickoff and intros * ​​10a: Ideation session * ​​11a: Pitches & team formation * ​​12p: Working lunch * ​​2p: Mentor visits * ​​5p: Free work (optional) * ​​9p: Doors close ​​**Sun, Mar 29** * ​9a: Doors open * ​10a: Mentor visits * ​​12p: Showcase * ​​1p: Final pitches & awards * ​​2p: Wrap *** # ​ FAQs ​**Do all ideas have a chance at getting funded?** ​​Not all ideas will move forward after initial pitches on Saturday. Once pitches are complete, we’ll vote for top ideas and form teams around the 4 – 7 ideas with the most votes. You must recruit **at least four total team members** (including the founder) to move forward and have a chance at getting funded on Sunday. If your idea doesn’t move forward, you can join another team! ​​**Do I have to submit my idea online prior to the event?** ​​Unlike previous years, we don’t have the option to submit your idea online prior to the event. Instead, everyone will be going through a brainstorming exercise on Saturday that’ll help you prepare for your initial pitch. ​​**Will we be working for 24 hours straight?** ​​Nope. The event is split over two days. You’ll be building on Saturday and pitching on Sunday. ​​**Do I have to pitch an idea?** ​​Nope. You can also simply join a team. ​​**What types of entrepreneurs does GBH support?** ​​While GBH most often works with technology startups, we support *any* organization (for- or non-profit) that makes an impact on health in the US or across the world.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

**Summary** Celebrate America's 250th year and the [Columbus Clippers'](https://www.milb.com/columbus) 50th season by watching [Franklin County's](https://en.wikipedia.org/wiki/Columbus_Clippers) best team play the [best game in the world](https://www.brainyquote.com/quotes/babe_ruth_140116) at [one of the ten best](https://www.dispatch.com/story/sports/minors/2025/03/26/huntington-park-voted-top-10-minor-league-ballparks-usa-today-10best-awards/82656048007/) baseball stadiums in the United States in their 2026 home Saturday opener! The first pitch is scheduled for 4:05 p.m. The gates always open an hour before the scheduled first pitch. I'm usually at the ballpark a half an hour before the scheduled first pitch. Clippers' games usually last around two and a half hours. Being a few minutes early will help us secure good seats. **Parking** I personally always like to park in the [McConnell Garage](https://www.google.com/maps/place/McConnell+Garage/@39.9685114,-83.0103938,17z/data=!4m6!3m5!1s0x88388f24145462d1:0x6238c0f0c851ab70!8m2!3d39.9692957!4d-83.0081175!16s%2Fg%2F1jkw6y27y?entry=ttu&g_ep=EgoyMDI1MTExNi4wIKXMDSoASAFQAw%3D%3D). If nothing else is going on in the area, this should be $7. However, I've also seen it be as high as $22. I can't say for certain what it will be for this game, but once I know, I will post in the comments. Alternately, there are other lots in the area you can try which will probably be a few dollars cheaper. [Here is a map](https://img.mlbstatic.com/milb-images/image/upload/q_auto/milb/ernng44ya2xkr4wbheql) of all the garages and lots surrounding the stadium. Keep in mind that many of these are outdoor lots and your car will be out in the elements. If you decide to look for a different lot, I would mildly recommend either the Buggyworks Lot or the Broadbelt Lot, but I have never parked in either of these myself. Although it won't apply for this game, keep in mind that street parking is also free citywide in Columbus on [Sundays and holidays](https://www.columbus.gov/files/sharedassets/city/v/1/public-service/right-of-way-permit/on-street-parking-out-of-service-policy-and-procedure-final-8.15.2022-signed.pdf). **Where We'll Be** Here is a [map of the ballpark](https://img.mlbstatic.com/milb-images/image/upload/milb/qkqohbqjgtx5uwo6zkgn.pdf). We'll be sitting on Level 3 of the [Left Field Building](https://www.milb.com/columbus/ballpark/huntington-park) (aka the "AEP Power Pavilion"), which features a 110 foot bar with six open patios overlooking the field. This area is covered and will be out of any sun or rain that may transpire. If you enter the park through the Center Field Entrance (which is at the intersection of Nationwide Blvd. and Neil Ave.), there will be a door to your immediate right after you enter that leads to a staircase up into the Tower. This door is not well-marked, and if you've never been to Huntington Park before, you may wonder if you're actually allowed to go in and up the stairs. Yes, you are. We'll be on the Tower's "Level 3". I have uploaded to the Photos section of this event page, below, a picture of the sign you want look for after you ascend the stairs, so you'll know you're on the correct floor. **Tickets** Do not buy your tickets ahead of time. They will literally be twice as expensive if you buy them on Ticketmaster. Instead, go to the ticket window near the Center Field Entrance. Buy a *Standing Room Only* ticket (don't worry, you won't be standing), which will cost you a flat $8 with no other taxes or fees. These tickets never sell out, and this is the cheapest way to get into the park. **Carry-Ins** Per the team's [website](https://www.milb.com/columbus/ballpark/a-z-guide): "Soft-sided coolers are permitted in the general seating area [which is where we'll be], but not hard-sided coolers; also no alcohol, glass bottles, or cans will be permitted. SMALL bags or backpacks of food items and beverages in plastic bottles are ok. Reusable water bottles are permitted, but must be empty upon arrival. Diaper bags are allowed." I always bring a disposable plastic bottle of water and refill it as I need at the park. Bottled water at the game is something like 4 or 5 dollars. So if you want a bottle of water, I recommend bringing your own bottle instead of buying it at the park. **Food & Drink** The area we'll be in has burgers, hot dogs, salads, soft pretzels, ice cream, and other sorts of things you would expect at a baseball game. I've posted pics of the menu in the Photos section, below. The burger and fries are $14 plus tax, and they're not bad. (This is what I usually get.) The beer is *really* overpriced. It's like $9, or $20 for a pitcher. If there's some people to help me drink it, though, I'll buy a pitcher of Michelob Ultra. While we'll be on the penultimate floor of the Tower, the top floor (which has a great view, but is fully exposed to the elements) has a [Dirty Frank's](https://dirtyfranks.com/) hot dog stand. I've never gotten anything from there, though I've been told it's good. The Donatos pizza stand is also a very short walk away from where we'll be. I love Donatos, but the pizza is so expensive at the ballpark. It's like $9 for a personal-sized pepperoni. It is good, though. **Peroration** Let's (watch them) play ball!

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.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

**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.
