**Doing KPIs Right: a KEY to Analytics (and AI!) Impact!** On the one hand, KPIs are such a Business 101 concept that it may seem a little silly to dedicate an entire session to the topic. On the other hand, KPIs get handled so poorly so often that a case could be made that this meetup could just be one of the most impactful sessions of the entire year! We’re starting off the year at a new location: [COhatch Upper Arlington](https://www.cohatch.com/locations/columbus/upper-arlington/) but with a familiar speaker, Tim Wilson! We’ll be back at Rev1 in February, when the speaker will presumably not be Tim. Tim will make the case that effectively measuring performance of projects, campaigns, and initiatives (and even meetups!) should be a foundation for any data analytics program. Topics covered will include: the “two magic questions” of performance measurement, how to help business partners distinguish between outcomes and outputs, and effective tactics for collaboratively establishing KPI targets. He will also stick his neck out by demonstrating some of these techniques in real-time by measuring whether his talk lives up to the promise of this description! All CBUSDAW events are free thanks to our 2026 Sponsors: Clarivoy, Conductrics, What Box Consulting Group, and Piwik PRO. Check out [cbusdaw.com](https://cbusdaw.com) for more information.

**Format**: Hybrid (in-person and online) event **In-person location**: **Security Compass** 325 Front Street West, Unit 103 Toronto, ON M5V 2Y1 **Note:** In-person attendance is limited to **70 people**, in a **first-come, first-serve basis**. Doors will open at **6:00 PM**, with the event will start at **6:30 PM** (ET). For those who cannot attend in person, please join us virtually via the livestream! **Presentation Title:** **Privacy Components That Should Actually Matter to Development Teams** Many teams expect that privacy is taken care of by the company’s security program or addressed by the legal and compliance teams. Fact is, privacy is often lagging behind security when it comes to software development, and there are still obligations that need to make their way into the lifecycle. And, in many cases, devs never even see the obligations that exist on paper to clients! In each business function of Governance, Design, Implementation, Verification, and Operations, there are privacy considerations that need to be made. The earlier you can get these considerations locked in, the more time it saves you later when there’s an incident, a user exercising their rights, or simply scaling up! \-\-\- **This is a hybrid event!** You're welcome to join us online or in person. Thanks again to our wonderful sponsors at **Security Compass** for hosting us!

This involves configuring network security groups to control inbound and outbound traffic, ensuring that only legitimate traffic is allowed. Utilizing a centralized firewall for network security policies and threat protection is also essential. Leveraging native security features for continuous monitoring, threat detection, and security analytics can significantly enhance your security posture. By adhering to best practices and regularly reviewing and updating security configurations, organizations can maintain a robust and resilient network security posture in any cloud environment. This talk will give you an in-depth insight into implementing Azure network solutions that significantly strengthen network security posture. Attendees will learn about the critical role of Network Security Groups (NSGs) in controlling traffic to and from Azure resources, ensuring only legitimate traffic is allowed. The utilization of Azure Firewall for centralized network security policies and comprehensive threat protection will also be covered. The session will place strong emphasis on advanced network architecture designs such as micro-segmentation, which creates isolated network segments, significantly reducing the attack surface and limiting lateral movement within the network. By incorporating these sophisticated architecture designs and adhering to best practices, participants will gain invaluable knowledge on how to robustly secure their Azure environments, ultimately enhancing the overall security framework and resilience of their infrastructure.

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!

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

## 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/

This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. Topic TBD! While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Columbus Library - Northern Lights Branch in the Meeting Room 1C.

2026 may be the last year many developers write code by hand. We need coding agents to solve complex problems in production codebases, but vibe coding alone won’t get us there. Vibe coding is all gas, no brakes. It burns up the context window until the agent slips on its own slop. You can go fast at first, but the more you stuff into the context window, the more tangled its outputs get. While the industry is rapidly increasing code generation speed, we still have to understand, review, merge, and maintain what gets shipped. This talk featuring Michael Geiger will outline how coding agents (Claude Code + Gas Town) work and a framework for orchestrating them to solve complicated problems in complex codebases. It’s about steering the model: doing the research to align intent, planning the approach up front, implementing in parallel steps, and breaking early. Human judgment still matters, but it should be spent on high-leverage decisions: what to build, what to forbid, and “what is quality?”, not cleaning up slop. Attendees will leave with a checklist to identify workflow and environment gaps that hold agents back, so you and your team can ship higher-quality software starting tomorrow.

**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

*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! 😄
