Beste Java-ontwikkelaar, We nodigen je graag uit voor een fysieke Java Meetup bij de Belastingdienst over **DDD, Event Storming en Hexagonal Architecture** door Arjen Wassink & Cees van der Velde van Quintor. **Programma:** 17:45 Inloop 18:00 Indonesisch buffet (halal, koosjer & vegetarisch) 19:00 Presentatie **Domain Driven Design / Event Storming** 19:45 Pauze (koffie/thee) 20:15 Presentatie **Hexagonal Architecture** 21:00 Drankjes met hapjes 21:30 Afsluiting De presentaties worden in het Nederlands gegeven. **Betere systemen ontwikkelen met hulp van DDD, Event Storming en Hexagonal Architecture** Je hebt het vast wel eens meegemaakt dat je een software systeem onder handen krijgt die niet makkelijk te onderhouden, upgraden of uit te breiden is. Iedere aanpassing lijkt exponentieel veel tijd te vergen. Er kunnen verschillende oorzaken hiervoor zijn, maar vaak zie je dat er te veel afhankelijkheden in de sourcecode zijn, verantwoordelijkheden niet goed belegd zijn of het systeem niet goed aansluit op de werkelijkheid. In deze sessie gaan we in op hoe DDD, Event Storming en Hexagonal Architecture ons kan helpen deze punten te verbeteren aan de hand van een concrete casus, diagrammen en sourcecode. Zo gaan we in op: * hoe Event Storming kan helpen de brug te slaan tussen de ‘business’ en developers, zodat een systeem aansluit op de werkelijkheid * DDD artefacten input leveren voor het bepalen van een systeemarchitectuur met duidelijke verantwoordelijkheden en afhankelijkheden * Hexagonal Architecture handvatten biedt voor een software architectuur met minder functionele- en technisch afhankelijkheden Mis deze inspirerende kennissessie niet en ontdek hoe je jouw softwareprojecten toekomstbestendiger maakt! **Arjen Wassink** Arjen is een architect bij Quintor met 25 jaar ervaring in het bouwen, onderhouden en doorontwikkelen van verschillende soorten systemen met Java technologie. Met zijn brede techniek en vakmanschap interesse is hij instaat enterprise architecturen te vertalen naar systeem- en software architecturen, en werkwijzen die werken. Hiernaast verzorgt hij een minor cloud-native software development aan de Hogeschool Utrecht waarin hij nieuwe vakgenoten leert professioneel software te ontwikkelen voor de cloud. **Cees van der Velde** Cees is een ervaren business- en informatieanalist bij Quintor met een passie voor techniek. Zijn kracht ligt in het helder krijgen en begrijpen van vraagstukken en deze te vertalen naar een concrete oplossingen die aansluiten bij de behoeften van developers, zodat effectief het juiste systeem gebouwd wordt. **Deelname:** Deelname is gratis. **Locatie:** Belastingdienst Stationsplein 50 (naast het bus- en NS-station) 7311 NZ Apeldoorn **Opmerkingen:** * Vergeet uw paspoort of identiteitskaart niet mee te nemen. * Registreer met dezelfde achternaam als op uw paspoort of identiteitskaart. * Geef eventuele dieetwensen door, anders dan halal, koosjer en vegetarisch. * Wij raden u aan om met het openbaar vervoer of de fiets te komen. * Er zijn 30 parkeerplaatsen onder ons kantoor, navigatieadres Sophialaan 22 - 7311 PD Apeldoorn. * Overige parkeermogelijkheden: 1.

In this talk, we explore why UX is the space where brand promises are either proven or broken, and why, in the age of AI, alignment between brand and user experience has become a strategic imperative. Drawing on real-world examples, this talk reframes UX designers as brand storytellers, and UX deciders and stakeholders as guardians of trust. It also introduces an **AI-driven Brand Sentiment Analysis workflow**, showing how teams can translate user signals into actionable insights, and design experiences that don’t just function, but reinforce how a brand is felt, remembered, and believed. **Talk 2: The UX evolution: thriving in the age of intelligent systems** [David Grunewald](https://www.linkedin.com/in/davidgrunewald/), Founder of Pluginto.ai , AI-Strategist AI is fundamentally changing how UX professionals work, but it's amplifying our capabilities, not replacing them. This 45-minute session explores what's actually happening in 2026. You'll see real implementations from banking, healthcare, and other sectors: proactive systems that anticipate needs, conversational interfaces that adapt to individual patterns, and hyper-personalisation at scale. We'll examine **four trends reshaping UX practice and, more importantly, what they mean for your daily work**. What's being automated? What's gaining value? And what are the five essential skills that set you apart in an AI-augmented world? You'll leave with clarity on how to evolve your practice and confidence that your human expertise remains your competitive advantage. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

Naast je reguliere werk hebben velen van jullie een hobby project, bijbaan of side hustle, waar je trots op bent, blij van wordt of waar anderen iets van kunnen leren. Deze **36ste editie** zijn we op zoek naar die projecten: je huis volledig geautomatiseerd met home assistant, een webshop met kattenknuffels met een COBOL of Haskell backend, een mobiele app die je in je vrije tijd bouwt, een opensource project waar je aan werkt, een online spel dat je gemaakt hebt, een cursus of tutorial die je geschreven hebt. Inmiddels hebben we genoeg projecten om de avond te vullen, hieronder kun je lezen welke projecten we bespreken. **Locatie** Radboud Universiteit - HG00.071 van het Huygensgebouw, Heyendaalseweg 135, Nijmegen **Programma** *17:30 - 17:55 - Inloop + food/drinks.* *17:55 - 18:00 - Welkom en kick-off!* *18:00 - 20:15 - Presentaties* *20:15 - 21:00 - Netwerken & Napraten* **Projecten** In no particular order. **Karl van Heijster - Spreekbeurt over mijn blog.** Hoi, ik ben Karl, ik heb een blog (https://www.karlvanheijster.com/). Mijn blog helpt me een betere ontwikkelaar te worden, doordat het me dwingt wekelijks te reflecteren op mijn werk en ons vakgebied. Wil je ook beginnen met bloggen, maar je weet niet hoe? Ik geef tips! **Môshe van der Sterre - ring_o_roses: low-latency & memory-safe & ergonomic.** Ik heb een experimenteel low-latency performance framework gemaakt in Rust, op basis van de LMAX disruptor architectuur, maar met een ergonomische user-facing API geinspireerd door Bevy's ECS. **Stijn Spijker - Maak je eigen race-stoel** Hoe ik een Tesla autostoel heb omgebouwd naar een ESP32, zodat ik de stoel zelf kan instellen, en het bedieningspaneel uit lees. **Joris Zwart - Tetris4life** Het begon als een spelletje... in 35 jaar tijd bouwde ik \~35 versies van Tetris met verschillende programmeertalen, frameworks en paradigma's. **Jeroen Huinink - Jotihunt** Met onze scoutinggroep doen we elk jaar mee met de Jotihunt, een gedeeltelijk online spel waar bijna 70 groepen aan meedoen. Ik heb voor onze groep een web applicatie gemaakt die ons helpt om het spel te spelen. Een ideale applicatie om met wat dingen te experimenteren. In de laatste iteratie ben ik all-in gegaan op eventsourcing op een nodejs backend. **Harmi Praagman - Nia Domo** Wat doe je als je in een woonvereniging woont waar vreselijke ruzie ontstaat over wel of niet overstappen op WhatsApp in plaats van een mailinglijst? **Hein Ragas - Wanneer heb je smart lighting nodig, en waarom zou je dat niet zelf maken?** We gaan het hebben over CRTs, LEDs en 2.4GHz protocollen, en nemen kwast en schroevendraaier ter hand om zelf de perfecte belichting voor een keuken-eiland te maken. **Dick Abma - Energiemanagement @ Home** In een gemiddeld huishouden spelen verschillende energiedragers en verbruikers een rol. Om mijn zonnestroom optimaal te benutten, bouwde ik thuis een eigen energie­management­systeem. Met €150 aan standaard hardware – een Raspberry Pi, Zigbee-stekkers en een Zigbee-hub – is deze investering binnen één jaar terugverdiend. **Vito Minheere - Wegenbelasting** Ik ben zelf een open source python project begonnen om de wegenbelasting van voertuigen te berekenen en de berekening inzichtelijk te krijgen.

We delen onze doelen en maken plannen voor de komende week. Iedereen is welkom. We kijken er naar uit om jouw verhaal te horen.

Taucht ein in die Welt von GitOps! Euch erwarten zwei spannende Vorträge rund um FluxCD in der Praxis. Christian Fritz teilt seine Erfahrungen aus zwei Jahren produktivem GitOps-Einsatz – von Erfolgen bis zu Stolpersteinen. Thorsten Wussow zeigt live, wie Progressive Deployments mit Flagger und Istio für sichere und hochverfügbare Kubernetes-Deployments sorgen. Perfekt für alle, die GitOps evaluieren oder ihre bestehenden Setups optimieren möchten! **Dieses Meetup wird ausnahmsweise auf Deutsch sein und HYBRID\. \|** Zoom Link wird ein paar Tage vor dem Event in Meetup zu Verfügung gestellt. **\*\*\* AGENDA \*\*\*** * 18:30–19:00 Uhr \| Einlass mit Snacks und Getränken\. * 19:00 Uhr \| Begrüßung und Einführung \- Start des hybriden Meetups 19:05 Uhr \| GitOps Adventures aus der Praxis: Lessons Learned \- Zwei Jahre GitOps mit FluxCD in Produktion von Christian Fritz \(QAware GmbH\) ca\. 20:05 Uhr \| Flux mit Flagger und Istio \- Progressive Kubernetes Deployments von Thorsten Wussow \(Slix GmbH\) Anschließend: Weitere Snacks und Getränke und viel Zeit zum Networking mit allen Teilnehmern und Referenten. **\*\*\* ABSTRACTS \*\*\*** **GitOps Adventures aus der Praxis: Lessons Learned - Zwei Jahre GitOps mit FluxCD in Produktion von Christian Fritz (QAware GmbH)** Diese Etappe des GitOps Adventures erzählt aus dem wahren Leben: Seit zwei Jahren arbeite ich in einem Projekt, das schon zu diesem Zeitpunkt auf GitOps mit FluxCD setzte. In diesem Vortrag zeige ich unser aktuelles GitOps Setup und wie neue Features über unsere drei Stages in die Produktion gelangen. Dabei zeige ich die Vorteile wie bessere Reproduzierbarkeit und Effizienz, gehe aber auch auf Herausforderungen und Nachteile ein: von komplexen Fehleranalysen bis hin zu organisatorischen Stolpersteinen. Außerdem gebe ich einen Ausblick, wo wir noch Verbesserungspotenzial sehen. Dieser ehrliche Erfahrungsbericht bietet praktische Einblicke und Learnings für alle, die GitOps evaluieren oder weiterentwickeln wollen. **Flux mit Flagger und Istio - Progressive Kubernetes Deployments von Thorsten Wussow (Slix GmbH)** Heutzutage ist eine hohe Erreichbarkeit von Applikationen essentiell, auch bei einem Wechsel auf eine neue Version. Ebenso gibt es eine hohe Kadenz der Bereitstellungen. Dies birgt immer das Risiko, das sich Fehler in der neuen Version einschleichen, oder Ausfälle der Software während der Bereitstellung auftreten. Eine Möglichkeit das Risiko zu minimieren ist das Verwenden von verschiedenen Deploymentstrategien wie z.B. Blue/Green Deployments, Canary-Deployments oder A/B-Testing. Ein Tool das uns hier sehr gut unterstützen kann ist Flagger. In diesem Vortrag wird anhand von Live-Demos gezeigt wie mit Flagger im Zusammenspiel mit Flux, Istio (oder einem anderen ServiceMesh) oder einem IngressController diese Deploymentstrategien umgesetzt werden können. Auch werden die Unterschiede zwischen Canary Deployments, A/B Testing, Blue/Green Deployment und weiteren Strategien erläutert und wann man welche Methode verwenden kann. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* Während unserer Meetups werden Fotos aufgenommen.

\*This event will be **ONLINE ONLY** **Are you an experienced tech professional aiming for top-tier roles at MANGA, AI companies, hedge funds or just the next step?** Your experience is solid, but is your CV holding you back? * CV doesn't bring you more interviews ? * Get ghosted often? * Recruiters don't move you forward once they review it? * 100 applications and less than 12 interviews (industry average) Top-tier tech companies receive thousands of applications from qualified candidates. At the senior level, it’s no longer just about listing your skills - it’s about how you frame your impact, leadership, and technical depth. We are bringing in a **Senior Engineer directly from Amazon** to provide insider insights on exactly what hiring managers at major tech firms look for in senior-level applications. **This is not a generic resume workshop.** This is a deep dive into crafting a CV that gets noticed by decision-makers at the highest levels of tech. **What We Will Cover:** * **The MAANG Lens:** How a Senior Amazon Engineer reads a resume * **Impact vs. Duties:** Shifting your CV language to highlight measurable business outcomes rather than just job responsibilities. * **Senior Positioning:** How to effectively structure leadership, architecture, and system design experience. * **The "Red Flags":** Common mistakes that get even highly experienced candidates rejected by ATS or recruiters. **Who Should Attend:** ⚠️ **Please Note:** This event is tailored for **experienced professionals** in the tech industry (e.g., Senior Software Engineers and tech professionals with more than 2 years of experience). **RSVP today to elevate your career prospects.** **Hosted by TopCoding**

**ArnhemJUG** We are excited to announce the second meetup of 2026. OpenValue Arnhem is once again hosting us for the February meetup! **Agenda** * 17:00 CET walk-in * 17:30 – 18:30 Food and drinks * 18:30 – 19:30 talk: **Catching the 137-Killer: A Java Memory Forensics Investigation** by **Martijn Dashorst** * 19:30 – 19:45 break * 19:45 – 20:45 talk: **Building AI Agent Platforms: Architecture, Communication, and Standards** by **Pascal Wilbrink** * 20:45 – 21:30 drinks **Catching the 137-Killer: A Java Memory Forensics Investigation** Your Java application is running smoothly, blissfully unaware of the danger lurking just around the corner. Then—without warning—it vanishes without a trace. Upon investigation, you discover the virtual remains of countless slain JVMs, each marked with the same cryptic number: 137. A serial killer is on the loose in your cluster. This true crime investigation will walk you through the differences between JVM memory areas, the mechanics of container OOMKills, analysing Grafana dashboards for memory and thread anomalies, interpreting heap dumps, and utilising JVM Native Memory Tracking (NMT) to uncover hidden native memory consumption. You’ll master practical forensic techniques and proven prevention strategies—from memory tuning tactics and balancing heap vs. non-heap allocations to leveraging large language models (LLMs) for advanced forensic analysis. These skills will help ensure your applications stay alive—even when something’s out to get them. Just like in a real murder mystery, we may not know whodunnit... but with Martijn Dashorst leading the investigation, you're sure to get closer to the truth. **About Martijn Dashorst** My Java experience is finally old enough to drive, vote and drink a beer (not all at once). One of the remaining Eclipse users, loves Java, relationship with Maven is complicated. Martijn Dashorst has worked since 2004 at Topicus and has used Java since 2002. Loves server-side Java. You might know him from Apache Wicket—he's dabbled somewhat in that framework. Loves his family and cats, finds Douglas Adams' description of the Sirius Cybernetics Corporation's technology very apt to the current technology landscape. **Building AI Agent Platforms: Architecture, Communication, and Standards** 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 Wilbrink** 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.

Met de interactieve CTF‑opdrachten leer je niet alleen hoe deze problemen ontstaan en misbruikt worden, maar vooral hoe je ze direct kunt toepassen en voorkomen in je dagelijkse werk. **Wanneer:** Donderdag 26 februari 2026 **Wat:** Cybersecurity in de Praktijk: Hands-on met Onyx **Voor wie:** Iedereen die nieuwsgierig is en wil leren **Agenda** 14:45 - 15:00 - Inloop 15:00 - 18:00 - Opening en introductie Praktijkvoorbeelden: Wat zijn wij in het echt tegengekomen Security misconfiguration: Gezamelijke spot-de-fout met code-snippets CTF opdrachten 18:00 - 19:00 - Eten en napraten We zien je graag op de Techday!

**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
