**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** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **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)

Why are we unhappy? Where does emotional pain come from? Studies show that people who suffer from long-term emotional pain have painful experiences in their lives that were never fully resolved in their mind. In other words, there were issues in the past that were not completely dealt with. This can include abuse in childhood, breakups, divorce, death of a loved one, to name a few. How do you know whether you have gotten over something painful? Here is an easy test: Do you still have attention on what had happened to you? For instance, do you still find yourself thinking about something painful that you went through? If you are, then you are not over it. In fact, in severe cases, people find themselves playing a "tape" in their mind over and over again. So how do you heal from your past? How do you stop the "tape" playing in your mind? In this meeting, you will learn a technique to help you with that. Come join us! 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 Dianetics and Scientology life improvement center.

*GOhio!* turns 8!! 🥳 Come celebrate with us at [Pins Mechanical](https://www.pinsbar.com/locations/easton)! 😄 **Summary** Pins Mechanical Co. is a social entertainment venue that combines old-school games like duckpin bowling, pinball, and other classic arcade and table games with craft cocktails, local beers, and punch. The vintage-industrial atmosphere is designed for playful, face-to-face gatherings with friends, family, and colleagues, offering a casual and lively alternative to a typical bar. Pins' Easton location spans over 38,000 square feet, making it the largest in the United States. This massive entertainment venue features two floors, a mezzanine level with stadium seating, and three full-service bars. It offers 16 duckpin bowling lanes, two indoor bocce courts, and more than 60 classic and modern pinball and arcade games. For additional fun, the location is known for its two outdoor patios, an indoor slide, and an expanded patio pong setup. **Activities** As noted below, some machines take actual quarters. Pins has two change machines (one downstairs and one upstairs) that accept ones, fives, or tens (only), and return quarters (only). * *Duckpin Bowling* [Like Bowling](https://en.wikipedia.org/wiki/Duckpin_bowling) but with smaller balls, stubby pins, and no oil on the lanes. The cost is $9 per game per person. * *Pinball* [Who](https://en.wikipedia.org/wiki/The_Who)'s a [wizard](https://en.wikipedia.org/wiki/Pinball_Wizard) on these [retro machines](https://pinballmap.com/map/?by_location_id=15311)? At $1 per play, everyone! Takes quarters. * *Arcade* Play classics like Gorf, Pac-Man, Gorf, Donkey Kong, Gorf, Galaga, and Gorf! The best part is, there's Gorf! And all the arcade games are free! * *Patio Pong* The classic college party staple but bigger. Instead of tossing a ping pong ball into cups, you use a regular ball and oversized buckets. There are two of these upstairs, and they're both free! * *Ping Pong* The most popular sport in China! They have two ping pong tables downstairs and two more ping pong tables upstairs. For those of you who have studied topological spaces and set theory, you will know this means they have four total ping pong tables. They have bubble gum dispensers with ping pong balls in them for 25¢ each. The dispensers take quarters. However, they also have racks where they store the ping pong paddles, and in these racks are slots for ping pong balls. It's not uncommon to see balls already here, so there's a chance you may be able to play ping pong for free if you want to. * *Hookie* You can't put your eye out! The safe alternative to darts: Hook thrown rings on a board. Outdoors on the upstairs patio, and free! * *Bocce* Like bowling, except there’s turf and a lot more balls. You can also knock your opponent’s balls out of the way. There are two of these upstairs, and they're both free! * *Foosball* Everyone loves [foosball](https://en.wikipedia.org/wiki/Table_football)! 50¢ a game. Takes quarters. * *Giant Jenga* Stack massive wooden blocks into a tower, then take turns pulling out one block at a time without collapsing the tower. There are four of these sprinkled throughout the venue (two downstairs and two upstairs, with one on each patio), and they're all free! * *Skeeball* There are three skeeball machines on the first floor (near the Gorf machine!), and they're all free! * *Giant Connect Four* On the outdoor patio upstairs, and free! * *Bubble Hockey* This is upstairs. Up to four people can play at once, and it costs $1. Takes quarters. * *Cornhole* There are two cornhole lanes upstairs, and they're both free! * *Basketball* There are two basketball machines downstairs. They're tucked behind the downstairs bar, so they're not always obvious unless you go look for them. They're $2 per play, and they take quarters. * *NES and Sega Genesis video games* These are collections, downstairs (near the Gorf machine!), of video games that you can play for free! * *The Big Metal Indoor Slide* This large two-story slide is for kids, and certainly no adults would ride this. After all, it's not like it's free or anything. **Outdoor Patio** Pins at Easton actually has two outdoor patios. But for our purposes, only the upstairs one matters. See, it will be winter and likely cold. But their upstairs patio has multiple ceiling heaters and two massive gas fire pits that put out a ton of heat. Sitting out here may be a real option. As mentioned above, the upstairs outdoor patio has one of the venue's two Patio Pong setups, one of their multiple Giant Jengas, the Giant Connect Four, and Hookie. **Food** Pins doesn't serve food, but there's a [Mikey's Late Night Slice](https://www.latenightslice.com/) next door. This Mikey's is basically an extension of the Easton Pins; there's a large open doorway between both establishments. Mikey's has a fountain dispenser with Coke products. You can also get Coke and Diet Coke (but not Coke Zero, like you can at Mikey's) at the bars in Pins, but I think the quality of the soda pop from Mikey's fountain is better than that from the bar hoses Pins uses to dispense soft drinks. You are also quite allowed at Pins to either bring food in or order it in via your favorite delivery app. **Parking** I recommend parking in the [Worth Garage](https://eastontowncenter.com/wp-content/uploads/2025/09/parking-at-easton-updated-file-sept-25.pdf). It's literally right next door to Pins, and it's free as long as you park on Level 2 or above. They recently started charging people to park on Level 1, and you pay for parking on this level the same way you pay for street parking in Columbus, with the [ParkColumbus](https://play.google.com/store/apps/details?id=com.parkmobile.parkcolumbus&hl=en_US&pli=1) app. I've seen them enforce this by ticketing people's cars, but I don't know how they actually compel payment. The garage is not a public street that actual cops can write you tickets for parking illegally on. If you have an actual ticket from a cop that you don't pay, they can go so far as to issue a warrant for your arrest. But all Easton has, seemingly, is, "[Please pay our ticket](https://eastonpreferredpark.com/)." Still, in my ongoing efforts to eliminate needless stress and aggravation from my life, I just park above the first Level. The actual address of the garage is [4049 Worth Ave, Columbus, OH 43219](https://www.google.com/maps/place/4049+Worth+Ave,+Columbus,+OH+43219/@40.0542293,-82.9137962,17z/data=!3m1!4b1!4m6!3m5!1s0x88388a86de3af559:0xc1dc8b4661fc834f!8m2!3d40.0542293!4d-82.9137962!16s%2Fg%2F11sgzjp4ml?entry=ttu&g_ep=EgoyMDI1MDkyNC4wIKXMDSoASAFQAw%3D%3D). However, your GPS is stupid. The actual entrances to the garage are on the cross steets Brighton Rose Way and Fenlon St, not Worth Ave. Just keep this in mind once you get to the garage. **Where we'll meet** I'll post in the comments where I am. People will obviously want to explore different areas of the venue over the course of the event (and there's a lot to explore), but please just let me know (as in, come find me) once you've arrived. **Peroration** Come on out and say hi! 😄

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
