Exploratory Testing

The playbook for AI agent integration is becoming predictable: build an MCP server, expose your APIs as tools, and define the rules in prompts. That approach works, but it often pushes workflow and guardrails into client-side logic, where they are harder to enforce and easier to bypass. This talk presents a different approach. HATEOAS (Hypermedia As The Engine Of Application State)—a largely overlooked part of REST—allows an API to describe allowed actions and constraints at runtime. That makes it a natural fit for agents, which need clear, machine-readable guidance about what they can safely do next. We’ll show this in action with MoneyMate, an AI agent that performs sensitive operations such as money transfers. Using the Spring HATEOAS project, the agent is guided entirely by the API rather than by hardcoded tools or fragile prompt logic. AI hype aside, this is ultimately a talk about architectural validation. For years, HATEOAS was the hill REST purists loved to die on—complete with finger-wagging about “doing REST correctly”—while everyone else quietly shipped simple JSON and moved on. It turns out the purists weren’t wrong—just 20 years early. Come see why that extra structure finally pays off when your client is an LLM. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu.

**Agentic SDLC** Software delivery is entering its next phase—one where the SDLC doesn’t just execute, it collaborates. Agentic SDLC brings AI out of the sidelines and embeds it across every phase of the lifecycle—from planning and coding to testing, deployment, and operations. These aren’t passive tools waiting for prompts—they’re proactive teammates that anticipate needs, automate repetitive work, surface risks early, and keep delivery flowing. In this session, we’ll explore how intelligent agents are reshaping the entire SDLC. Think beyond code completion: agents that refine backlog items, generate and review pull requests, create meaningful tests, enforce standards, flag risks before they become incidents, and even monitor production with context. We’ll walk through real-world scenarios and practical implementations showing how teams are using agentic approaches to boost productivity, improve code quality, and accelerate delivery—without sacrificing control or flexibility. You’ll also see how this can be done across a diverse ecosystem of tools and platforms—cloud or on-prem, open-source or commercial—so you can adopt what works best for your environment. Whether you’re a developer, tester, architect, or team lead, you’ll leave with concrete patterns and ideas to evolve your SDLC into a smarter, more adaptive system—where AI doesn’t replace the team, but makes every part of it stronger. **Speaker: Max Yermakhanov** *DevOps guy, Automagically* A passionate and forward-thinking DevOps guy, Max brings over 20+ years of experience helping organizations modernize how they build and deliver software.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/xwjDdVSw3E **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

Back with something slower, greener, and a little more relaxed. Saturday 2nd May at 2pm. We shall explore the cute dog parks. Then head into a beautiful indoor greenhouse right in the middle of Toronto. We will then walk to a local lowkey museum (if it is open). Later end with coffee and light bites at a nearby café.

It feels like we just saw each other 🤷. Join members of the local design and UX community for our monthly breakfast. For May we’re stopping in for Rooh’s popup breakfast/cafe concept. You know someone is getting the lobster yuzu croissant, and that’s not even the prettiest thing on the menu!.

To do that, you’ll need to register at our website, [HERE](https://www.coreerocks.com/Events.aspx?ID=2026-Central-Ohio-Real-Estate-Investing-Expo-14-5-5-2026).) We’re serious about helping you succeed in real estate. That means not just teaching you—but putting you in the room with the people who help you get deals done. Every deal depends on people. The agent or wholesaler. The lender. The contractor. The title company. The insurance agent. The problem is that most investors meet those people slowly. This event fixes that. One room full of: • Lenders • Contractors • Title companies • Insurance providers • Property managers • And active local investors A place where you can: • Build your team • Find funding • Solve real problems • Make connections that lead to deals If you’re serious about real estate, this is a smart room to be in. Members and non-members at any level of knowledge and experience are welcome. This event is free. Remember, to actually reserve your seat, you have to go [HERE](https://www.coreerocks.com/Events.aspx?ID=2026-Central-Ohio-Real-Estate-Investing-Expo-14-5-5-2026) and register on our website!

The topic for May is "Ink" 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!

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!

If you are interested in selecting investment choices for your 401(k) or other workplace savings plan, minimizing your income tax liability, or identifying the most effective investments for your brokerage account, we are the group for you.
