🤖 AI agents aren't chatbots! They decide, they act, they call APIs, they handle data and when something goes wrong, you find out days later, if at all. Over the past twelve months, production agents have leaked credentials, executed unauthorized transactions, and exfiltrated confidential data through prompt injection. Classical security and QA playbooks don't catch these attack surfaces, because the trust boundary just moved, and most teams haven't caught up yet. We're gathering for an honest conversation - no theory, no vendor pitches. On the panel, practitioners who work on agent security every day, from people leading international open-source security frameworks to QA veterans who know first-hand why deterministic testing collapses in the face of non-deterministic AI. We'll talk about the new attack surfaces, real production incidents, and what every builder needs to know before shipping agents. Most AI security conversations happen behind closed doors. This one happens under the open Athens sky — accessible to all levels, beer in hand, in the city that invented public discourse.🍻 📅 **Thursday, May 28, 2026, 19:00**, we'll discuss the security of Agentic AI systems, real-world incidents, emerging attack surfaces, and what every builder needs to know before they ship. 📍 Where? **In the back courtyard of New York College, 38 Vasilissis Amalias Avenue, Athens 105 58** — a relaxed, open-air space in the heart of the city, ideal for conversation and networking. 🚌 Getting there: Right across from the National Garden: Metro: "Syntagma" Station (Lines 2 & 3) — 3 minutes on foot Tram: "Syntagma" Stop Buses: 040, 550, X14, 5, 15 (Stops "Amalias" or "Syntagma") Trolleybuses: 2, 4, 5, 11 (Stop "Syntagma") 👉 **Panel Discussion: Securing the Agentic Web** An honest conversation about the security challenges of agentic AI — what actually goes wrong in practice, what the new attack surfaces look like, and how you build AI agents that won't betray you when incidents hit. Accessible to all levels — no prior security background required. 👉 **Fireside Chat: Success Stories** Honest, first-hand accounts from teams inside Greek enterprises who deployed agentic AI into production and lived through what came next. They'll walk us through the risks they actually faced. 📋 **Program** **18:45 – 19:00: 🚪 Arrival & welcome** **19:00 – 19:30: 🎙️ Panel Discussion — Securing the Agentic Web (30')** * *John Sotiropoulos* **19:30 – 20:00: 🔥 Fireside Chat — Success Stories (30')** * *Romanos Matthaiasos* **20:00 – 20:15: 🙋‍♂️🙋‍♀️ Q&A — open questions from the audience (15')** **20:15 – 21:30: 🍻 Networking & Drinks (75')** 🎯 **Why you should come** 1. You'll understand how agentic AI systems fail in real scenarios — not theory, but what has actually happened 2. You'll get practical insights from people working actively in AI security 3. You'll meet builders and founders facing the same challenges as you 4. You'll connect with the Greek AI community at the largest tech gathering of the year 5. And you'll have an unforgettable evening — with a beer in hand, under the Athenian sky 🍻 **Seats are running out faster than the first beer. Book now!** 🚨 🚀 **Supporters** Thanks to New York College for hosting us and to the Panathenea 2026 team for the framework. This event is supported by HumanBound — an AI agent security testing platform that helps teams find vulnerabilities in their agents before attackers do. 🎤 **Speakers** * **John Sotiropoulos** — Leader of the global OWASP Agentic AI Top 10 initiative, one of the most important open-source frameworks for AI agent security worldwide. * **Romanos Matthaiasos** — Software QA Manager at Eurolife FFH & ISTQB Instructor.

Ready to hand over the code entirely to AI agents and just focus on system design? So are we. Until we need to debug whatever hallucinated dependency the agent snuck into production, let's do an Architecture Kata. **What is an Architecture Kata?** An Architecture Kata is a structured group exercise where we tackle realistic design problems as peers by sketching, questioning, and iterating out loud. No single "right" answer. Just engineers working towards a solution together. **How we'll spend the evening** * **Scenario Drop** (15 min): We introduce a concrete business situation. * **Small Group Sketching** (60 min): Break into groups of 3-5. Draw, argue, change your mind, start over. The goal isn't a perfect diagram, but the rationale behind it. * **Walkthrough & Peer Review** (30 min): Groups share where they landed. The rest of us ask "what if?" and "have you considered?" We learn from each other's blind spots. **Who This Is For** * Engineers who want to practice designing out loud * Anyone with interest/experience in software architecture (Optional) Your laptop, though markers and whiteboards do most of the work **Sponsors** Our sponsors for this meetup are [Yodeck](https://www.yodeck.com/) \- who are not only kindly providing the venue\, free of charge\, but who will also treat us to some snacks / drinks for the networking session after the meetup\! Do stick around and say hi!

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 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 speakers for our Monthly Meetups!

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
