Met veel enthousiasme kondigen we de eerste meetup van 2026 aan, gehost bij Flink Software in Nijmegen. **Programma** 17:30 - 18:00 Inloop + hapje/drankje 18:00 - 18:45 **Tame your Llama, run AI in Java** \- Lutske de Leeuw 18:45 - 19:00 Pauze 19:00 - 20:00 **Breaking Bad (Code): An Interactive Guide to Security Code Review** \- Arjan Gelderblom \(First8 Conclusion\) 20:05 - 21:00 Netwerken en gezelligheid **Tame your Llama, run AI in Java** \- Lutske de Leeuw Ready to supercharge Java projects with AI? This session will demonstrate how Java developers can harness the power of Llama models locally to create AI-driven applications without needing a deep machine learning background. The session begins with the essentials, covering environment setup, and dives into loading and running Llama models in Java. Through hands-on examples, attendees will learn how to use Llama for powerful tasks like natural language processing and classification, bringing intelligent features to Java applications. Forget complicated setups and steep learning curves. By the end of the session, participants will be equipped to incorporate advanced AI into their Java apps with ease. Whether enhancing user experiences, automating tasks, or improving decision-making, this talk provides practical skills to bring cutting-edge AI to any project. Takeaways: \- How to set up and run Llama models in a Java environment\. \- Practical applications of Llama for natural language processing and classification\. \- How to seamlessly integrate AI\-driven functionality into existing Java projects\. Don’t miss the opportunity to explore the world of AI with Java. This session offers a code-centric, hands-on dive into Llama, leaving attendees with actionable skills ready for immediate use in real-world applications. **Breaking Bad (Code): An Interactive Guide to Security Code Review** \- Arjan Gelderblom \(First8 Conclusion\) Most security vulnerabilities slip through code review not because they're cleverly hidden, but because reviewers don't know what patterns to recognize. While automated tools catch obvious flaws, the subtle logic errors and architectural weaknesses that lead to real breaches require a trained human eye—and most developers have never been taught how to look. This interactive talk transforms participants from passive code readers into active security reviewers. Through five progressively challenging code review exercises drawn from real-world vulnerabilities, attendees will learn to spot security flaws across multiple vulnerability categories. Between challenges, we'll build a systematic framework for security-focused code review: developing an attacker's mindset, recognizing dangerous patterns, performing data flow analysis, and prioritizing security concerns based on risk. This session is designed for developers at any experience level who conduct or participate in code reviews. No prior security expertise required—just bring your ability to read code and willingness to think like an attacker. **We kijken ernaar uit je te zien op 5 maart! 👋**

Hello architecture enthusiasts! We're excited to announce our next meetup exploring the emerging world of AI agent platforms and orchestration! Join us for an evening where we'll tackle the architectural challenges of moving from standalone AI models to connected, intelligent ecosystems. Makan will share insights on how a capability mesh could solve today's AI orchestration challenges, while Pascal will dive into the practical patterns, protocols, and standards for building AI agent platforms. Come hungry for both knowledge and food — we've got plenty of both, plus drinks and great networking opportunities at OpenValue's Utrecht office. Both sessions will be presented in English. RSVP now for an evening of learning and connection! **Getting Here** Directions: [https://www.openvalue.eu/route/#utrecht](https://www.openvalue.eu/route/#utrecht). Parking is free. The office is within walking distance of Utrecht Zuilen train station. **Agenda** 17:30 Doors open 18:00 Food 18:30 Talk 1: Capability Mesh: Enabling Orchestration through Semantic Integration 19:30 Break 19:45 Talk 2: Building AI Agent Platforms: Architecture, Communication, and Standards 20:45 Drinks, fun, networking **Talk 1: Capability Mesh: Enabling Orchestration through Semantic Integration** *Makan Sepehrifar, Principal Engineer at Code Nomads* Ten years ago, microservices chaos led to "Service Mesh" solving the discoverability problem by replacing network endpoints with meaningful references, enabling scalability and observability. It worked brilliantly for connecting services. Today we're living through the same cycle with Generative AI and Agents, but the chaos is about integration, not networking. The old problems discoverability, scalability, observability are back because orchestrators now pick agents by capability, not name. Plus we face new challenges: explainability of agent actions and the possibility of unintended actions due to the non-deterministic nature of large language models. We need the same evolutionary leap from "Service Mesh" to "Capability Mesh" shifting from technical service contracts to semantic capability integration for autonomous AI. Key Topics and Take Aways: * From OpenAPI to MCP: The Protocol Shift in Agentic AI * MCP Gateways: The New Control Plane * Capability Hierarchies: Composing Agents at Scale * Human-on-the-Loop: Redefining Our Role in Agent Systems * Policy as Code: Governing Autonomous Agents * Observability & Safety: Tracing Agent Behavior *About Makan* Makan Sepehrifar is a software architect whose fascination with the intricacies of organizational behavior and cognitive psychology has led him to redefine the way technology interfaces with human understanding. Looking at software architecture as a craftsmanship process, he realized that the more abstract you look at it, the more complexities arises. His career has been a testament to his commitment to bridging the gap between technology and human behavior, resulting in innovative software solutions that not only work efficiently but also self-adaptive teams that embrace the mindset of agile. **Talk 2: Building AI Agent Platforms: Architecture, Communication, and Standards** *Pascal Wilbrink, Senior Software Engineer at OpenValue* AI systems evolve from standalone models into connected, agent-based ecosystems, new architectural patterns, protocols, and standards are emerging. Concepts such as AGUI, A2A, A2UI, and MCP-based applications are changing how intelligent systems are designed and integrated. This presentation explains how these approaches affect system structure, responsibilities, and interoperability. Using architectural diagrams, it shows how AI agent applications communicate and collaborate through standardized interfaces, and provides guidance on building scalable and maintainable AI platforms. *About Pascal* Pascal is a senior software engineer at OpenValue with over a decade of experience and a strong interest in applied AI and intelligent automation. He enjoys exploring how technology can make developers’ lives easier and software more resilient. When he’s not experimenting with new ideas or building open-source tools, Pascal likes to learn by doing and turning complex problems into practical solutions.

Veel organisaties sturen voorraadbeheer nog aan op basis van statische planningen of historische data. In omgevingen met sterk fluctuerende vraag, zoals in de horeca, leidt dit vaak tot inefficiënte bevoorrading, misgelopen omzet en onnodige kosten. In deze workshop werken we met een real‑time use case rondom een keten van koffiebars, waarbij live wordt gemonitord welke dranken worden verkocht en hoeveel koffiebonen, melk en andere ingrediënten daarbij worden verbruikt. Deze events worden continu verwerkt om actuele voorraadniveaus te berekenen en te voorspellen wanneer aanvulling nodig is. Door real-time inzicht kan er ingespeeld worden op belangrijke externe factoren, zoals automatisch bevoorrading vóór de ochtendspits, of het aanpassen van de planning bij hogere bezoekerspieken zoals bij regenachtig weer of grote evenementen in de buurt. 🔍 Waar gaan deelnemers mee aan de slag? De focus ligt op het opzetten van een event‑gedreven architectuur in Microsoft Fabric, waarbij deelnemers hands‑on werken met: • Eventstream & Eventhouse Voor het ingesteren, transformeren en opslaan van real‑time “order events” (bijv. Latte besteld om 08:12:03) verbruikte hoeveelheden ingrediënten (bijv. 18g koffiebonen, 250ml melk) • KQL voor real-time analyse Deelnemers gebruiken Kusto Query Language om real‑time aggregaties te maken (verbruik per minuut/uur) windowing toe te passen (short-term spikes herkennen) trends te detecteren (dagdelen, weersinvloeden, promoties) • Real-Time Analytics Voor het visualiseren van actuele voorraadniveaus per winkel het instellen van alerts bij laag voorraadniveau het voorspellen van aanvulmomenten (bijv. “koffiebonen op binnen 2 uur”) Wil je meer weten over real time data analyse, hoe je dit aanpakt en ook hoe je zelf aan de slag hiermee kunt gaan met Microsoft Fabric? Sluit aan op donderdagavond 5 maart op ons kantoor op steenworp afstand van het station van 's-Hertogenbosch. Programma: 17.00 - 17.30: Inloop en ontvangst 17.30 - 18.15: Buffet 18.15 - 20.00: Uitleg & Workshop ''Real-time data-analyse en slim voorraadbeheer met Microsoft Fabric'' 20.00: Napraten met een drankje Parkeren kan bij de P&R naast ons pand (wij verzorgen een uitrijkaart).

***In this meetup, we explore why traditional feedback systems fail and what it really takes to build a culture of dialogue.*** ***\*\*\*Attention! This is an in-person event only. We need a minimum of 10 attendees for gaining the most value (besides the hosts). We will notice you in advance for a go/no go around February the 20th, 2026 \*\*\**** *Drawing from real consultancy experience and organizational case studies, we’ll unpack how feedback is shaped by deeply embedded systems of judgment, social conditioning, business culture, and biological responses to threat.* **Cool concrete case studies shared of different organizations with a diversity of challenges.** Let’s be honest: the word “feedback” can make your stomach clench. We brace for awkward conversations that end in painful silence, or we swallow our frustration to keep the peace. We worry about disrupting relationships or being misunderstood, so we often say nothing at all. But what is the true cost of this silence? Misunderstandings fester, trust erodes, and team morale quietly slips away. Ironically, by avoiding feedback to protect our relationships, we often end up creating the very disconnection we feared. As a result, we've developed a deeply unhelpful relationship with feedback treating it as a confrontation to be dreaded rather than a conversation for connection and growth. **Shift consciousness, habits, and leadership behavior at every level. Explore how to create cultures of dialogue instead of confrontation, where people feel seen, heard, and able to grow.** *** ### **Agenda** 17:30 - 18:00 Walk in 18:00 - 18:45 * Welcome & personal story * Current Systematics of Feedback 18:45 - 19:15 FOOOOD 19:15 - 20:30 * Clear Case Studies Example(s) of Feedback Systematics * Change the System of Feedback 20:30 Netwerk + Walk Out 21:00 Please go home you lovely people **Who Should Attend:** * Leaders * HR Professionals * Scrum Masters * Agile Coaches * Change Agents * Anyone who want to move beyond labels and is interested in creating a feedback culture.

'ALL THE LIGHT WE CANNOT SEE' by Anthony Doerr 'Marie-Laure lives with her father in Paris near the Museum of Natural History where he works as the master of its thousands of locks. When she is six, Marie-Laure goes blind and her father builds a perfect miniature of their neighborhood so she can memorize it by touch and navigate her way home. When she is twelve, the Nazis occupy Paris, and father and daughter flee to the walled citadel of Saint-Malo, where Marie-Laure's reclusive great uncle lives in a tall house by the sea. With them they carry what might be the museum’s most valuable and dangerous jewel. In a mining town in Germany, the orphan Werner grows up with his younger sister, enchanted by a crude radio they find. Werner becomes an expert at building and fixing these crucial new instruments, a talent that wins him a place at a brutal academy for Hitler Youth, then a special assignment to track the Resistance. More and more aware of the human cost of his intelligence, Werner travels through the heart of the war and, finally, into Saint-Malo, where his story and Marie-Laure’s converge. Doerr's stunning sense of physical detail and gorgeous metaphors”(San Francisco Chronicle) are dazzling. Deftly interweaving the lives of Marie-Laure and Werner, he illuminates the ways, against all odds, people try to be good to one another. Ten years in the writing, All the Light We Cannot See is a magnificent, deeply moving novel from a writer “whose sentences never fail to thrill” ( Los Angeles Times). ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.

We’re heading out onto a **brand new trail** on the Veluwe, one we’ve never walked before. That alone makes this hike extra exciting. New paths, new views, and that lovely feeling of discovery from start to finish. From the start we dive **straight into the forest**, following winding woodland paths that slowly pull us deeper into the heart of the Veluwe. The forest feels calm and spacious, and with spring just around the corner you’ll notice nature quietly waking up. Budding trees, fresh greens, birds getting busier. It’s that in between season where everything is preparing itself. After several kilometers of forest walking, the landscape opens up as we reach the **Hoog Soerensche Veld**. Wide open fields, big skies, and that classic Veluwe contrast between forest and heath. From here we continue towards the **Asselsche Heide**, one of the quieter and more scenic parts of the Veluwe. This section offers lovely viewpoints, open heathland, and long sightlines that really give you that spacious Veluwe feeling. We finish where we started, completing a **full loop hike** through forests, open fields, and heathland. **📍When and where to meet?** We’ll meet at 11h30 at busstop Hoog Buurloseweg https://maps.app.goo.gl/sCMJ8Kg7MTUcYu1j7 ⏰ **We start walking a few minutes after meeting up** — we don’t wait for latecomers, as the forest calls and daylight is short this time of year. **🚗 Coming by car?** You can park here but please also do your own research: https://maps.app.goo.gl/sCMJ8Kg7MTUcYu1j7 **⏸️ Planned Breaks** After 9 km: 30 min lunch break in nature After 15 km: 15 min break in nature **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list.

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!
