Join us for some focused writing time. All writers and all experience levels are welcome and don’t worry, no one will see what you've written. This session is about getting your writing done and meeting other writers in your area. When you show up, say hello to everyone, grab a drink, and get your writing tools ready. Once you’re all settled, take some time to chat with your fellow writers. Once everyone’s arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session. Afterward, we’ll have time to chat and get to know each other. We often talk about our successes and challenges as writers. If you don’t have time to stick around, no worries! **A note about the format** We don’t host critiques or readings. These events are a safe space for writers of all skill levels and genres to work on their craft, so no one will read or critique your writing.

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!

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.

Do you feel introverted when you are in a group setting? Are you shy? Do other people have more fun than you do? There are simple life hacks you can use to improve your connection to others and improve your social life. Talking is one thing. Truly connecting is altogether another. It's the whole experience of connecting with people and forming relationships. It includes the joy, understanding, and love formed among people. * In our meetings, you will learn: * A simple life hack to increase your liking and tolerance of other people, or even of yourself! * How to become more interested and enjoy conversations with people. * How to be comfortable in social settings. * How to be yourself * How to become more extroverted and, * How to make connections with people. Feeling lonely, isolated, or bored? This local meeting is exactly what you need! Come join us! Be sure to click on the red "Attend" button below to come to the local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology life improvement center.

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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

**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)
