We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

Dear Illinois Prairie PUG members, Thank you to everyone who attended PG DATA 2026! The conference is over, but our meetups are back, and more Postgres content is coming! Those of you who attended our May meetup are already familiar with our new (hopefully permanent) location. For others, please note that we will meet at **Chicago Innovations, 1 W. Monroe**. This time, we are trying a two-talk format. \- Zach Paden will present the talk **Declarative schema management with pgschema.** \- Anna Bailliekove will present the talk **PostGIS Quick Start** More details on talks and speakers coming soon! *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:40 - Zach. Declarative schema management with pgschema. 6:45 - 7:10 Anna: PostGIS Quick Start 7:10 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing **Speaker**: Zach Paden Zach Paden is a tech lead at Symetra with experience ranging from scrappy startups, consulting, to large regulated enterprises. His work spans data platform, analytics and application development where he’s seen more than his fair share of projects get bogged down or catch on fire due to their schema management practices. **Talk Title:** *Declarative schema management with pgschema* **Talk description** Lots of app devs struggle to understand the concept of versioning database migrations, and managing the history of these migrations can become difficult even with existing tools. Using pgschema you can write pure-sql decoratively and let pgschema derive a series of valid online migrations. **Speaker:** Anna Bailliekova Anna Bailliekova has been moving data around professionally for 15 years. Currently a staff engineer XeoMatrix, she focuses on helping organizations mature their data engineering practice, optimization problems, and geospatial data applications. **Talk title:** PostGIS Quick Start **Talk description** PostgreSQL provides rich support for geospatial computing; using transportation examples, we will take a brief tour of these features for those who want to but have been scared to try. *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. \- You will notice the change in the RSVP form\. \- We are thankful to our hosts and promise to be responsible\. \- We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). \- We do not want to waste food\, so please indicate your dietary preferences\. \- We will not close RSVPs on the morning of the meetup\, but please do your best to RSVP in advance so we can order the appropriate amount of food and drinks\. \- We want to start offering **on-site daycare**. If you indicate on your RSVP that you are planning to use daycare, we will contact you closer to the event with more information. This meetup will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!

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.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Be prepared for an entirely different type of sci-fi movie! Unofficially, the second movie in director Lars von Trier's "Depression Trilogy," 2011 Melancholia depicts the events that occur before a rogue planet is about to collide with the earth. Considered by many to be a masterpiece, the film was included in BFI's 2022 Sight and Sound Poll of the greatest movies of all time. It is available at the library as well as on Kanopy.
