In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

If you enjoy knitting, crocheting, working with yarn, this is the group for you. Meet new friends, bring your projects, learn from others.
We normally meet a few times a month during the week from 6-8pm. We will occasionally meet on weekends during daytime hours.

Join us and work remotely together with like-minded UX folks. This is a last minute opportunity to get out at one of our favorites, [Junto](https://thejuntohotel.com/)! Plenty of seating is available in addition to a connected coffee shop and restaurant. I will be there 10-12 for sure, maybe longer. Feel free to come and go anytime during the day, and don't forget your charger and headphones!

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 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)

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).

While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome! Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here. Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings.

Bienvenue! Columbus French Conversation group invites you to our Saturday morning French conversation club. Expect a casual and welcoming atmosphere in which to learn french! I will bring my laptop so we can look up new vocabulary as needed! The venue is a beautiful French restaurant so you can really get into the zone :)

A classic Italian road comedy that was so good the film ministry recognized it as "culturally significant." Starring Vittorio Gassman and Jean-Louis Trintignant, the film shows that for young men in love the rules of the road are only suggestions. And the rules for love? Hey, this is an Italian picture! Oh to be young and filled with joie de vivre or la dolce vita. A french/italian fun filled movie with a surprising twist at the end. Do you have a fun memory from your youth?

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Join us as we get together to see SIRAT, an Oscar-nominated Best International Film from Spain that follows a father, accompanied by his son, goes looking for his missing daughter in North Africa. Here’s a description, trailer and our plan for this event: DESCRIPTION: A father, accompanied by his son arrive at a rave deep in the mountains of southern Morocco while searching for his daughter who vanished months ago at one of these endless, sleepless parties. As their search continues, the journey forces them to confront their own limits. The film is directed by Oliver Laxe and stars Sergi Lopez, Bruno Nunez Arjona and Richard Bellamy. TRAILER: https://www.youtube.com/watch?v=ww-IXHXvS70 BUZZ & ACCLAIM: SIRAT has already won numerous awards, including 4 at the 2025 Cannes Film Festival, along with the Chicago, Montclair and Toronto International Film Festivals! It also earned a whopping 11 nominations at the 40th Goya Awards, including Best Film and Director, and was nominated for Best International Feature Film and Best Sound at this year’s Academy Awards. The film is earning a stellar 92% positive rating on Rotten Tomatoes which calls it “an unforgettable exercise in tension” and “a brutal reminder that the journey can be more important than the destination.” PLAN: We’ll plan for a 7pm-ish showing and will confirm/announce details as the date gets closer. Once showtime is confirmed, advance purchase (via GFC website preferred) is advised! Once you have your ticket, please list your seat number in the Comments section of this event. PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! Look forward to seeing you there, Dan

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.
