AI isn’t just for techies anymore—it’s for everyone. Join us for a relaxed meetup where we chat about how AI shows up in everyday life. We’ll swap ideas, tips, and “wow… or huh?” moments about using AI for work, learning, creativity, and daily tasks. No experience needed, no presentations, no pressure—just open conversation and curiosity. Come hang out, ask questions, share what you’ve tried, or just listen and learn. All are welcome 🙂

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group × DevOps Columbus** 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, Columbus HashiCorp User Group, and DevOps Columbus 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/azure-cbus-2026/

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.
