**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)

**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

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! 😄

# **Band: The Pegheads; Caller: Liz Burkhart** Beginner lesson at 1:30, regular dancing begins at 2:00 pm NOTE THAT WE ARE TEMPORARILY DANCING IN THE AFTERNOON INSTEAD OF EVENING. Dance with us in the afternoon then you can still go out in the evening! **Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 1:30 - 2:00, followed by dancing 2:00 - 430. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. Please bring your own refillable water bottle.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/cbus-hug-2026/
