Two thirty-minute presentations followed by Beer & Pizza Speakers: ## From Bits to Collisions: Breaking and Defending Railway OT This session introduces **OT-Security-Lab**, a hands-on railway SCADA/PLC security lab that shows how cyber attacks can create real physical impacts. By simulating safety logic, control registers, and legacy protocols like Modbus TCP, the lab demonstrates how attackers can manipulate OT systems without exploits or malware. It also highlights how Blue Teams can detect these behaviors, helping bridge the gap between IT security and real-world OT environments. Bio: Christian Azuero is a cybersecurity specialist and Technical System Consultant at BMM Testlabs with over five years of experience across firewall auditing, threat detection, DFIR, and regulatory compliance. He designs hands-on Blue-Team and CTF learning environments, including the Hacker Escape Room platform used by students and cybersecurity communities across Australia. Christian holds an MSc in Network & Security from Monash University and multiple industry certifications, and is passionate about making cybersecurity and OT education accessible, practical, and fun.

**Important notice - Please use this link to register for the meetup** **https://luma.com/w01uummz** **Site Reliability Engineers vs Platform Engineers: Who Owns What?** Join us for a dynamic panel discussion exploring the evolving landscape of infrastructure and operations roles in modern tech organizations. As companies scale and technology stacks grow more complex, the lines between Site Reliability Engineering (SRE) and Platform Engineering can blur, overlap, or diverge entirely depending on organisational needs. This session brings together practitioners from both disciplines to unpack the core responsibilities, shared territories, and distinct ownership areas of each role. But here's where it gets interesting: ownership boundaries vary dramatically across organizations. At some companies, SREs build the platform. At others, Platform Engineers handle production reliability. Many teams share responsibilities for Kubernetes, observability tools, infrastructure as code, and deployment automation. Company size, maturity, culture, and technical stack all influence how these roles are defined and what each team owns. Our panelists will discuss real-world examples of how their organizations have drawn these boundaries, where collaboration is essential, where conflicts arise, and how to think about structuring these teams for success in your own context. Whether you're an SRE, Platform Engineer, engineering leader, or simply curious about these evolving disciplines, you'll leave with clarity on the distinctions, insights on common patterns, and practical perspectives on making these roles work together effectively.

Hey everyone We are putting on an in person OpenShift meetup on Wednesday 25 Feb. Come and join us to hear the latest capabilities for OpenShift 4.21, Roadmap, Virtualisation, GPU, AI & MCP servers and more. Having just returned from Red Hat One in Vegas we have a lot to share of what we have seen happening around the world. Its the usual time starting at 6pm with a 7:30pm finish as well as drinks and pizza! Look forward to seeing you there. OpenShift Meetup team https://www.redhat.com/en/blog/achieve-more-red-hat-openshift-421

**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

Join other experienced and aspiring agile coaches and professionals to: * develop and practice your coaching skills in a peer-to-peer environment * share current successes and challenges in your work environment and get support from each other * learn from each other, build better relationships and experiment with new ideas

The topic for March is "Our Bodies, Ourselves" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
