Critical Thinking

Tijdens de maakavonden van Meet Je Stad soldeer je je eigen meetkastje dat temperatuur, luchtvochtigheid en fijnstof\* kan meten. Het solderen is geschikt voor iedereen: van beginner tot expert! Daarnaast bieden we begeleiding, dus hoef je niet bang te zijn dat je er niet uit komt. Ter deelname betaal je €15 voor de materialen. Vaak lukt het niet om al het soldeerwerk binnen één avond af te krijgen, maar dit is geen probleem; tijdens onze volgende maakavonden kun je langskomen om je werk af te maken. Inmiddels zijn er in de stad Utrecht nu zo’n 150 mensen die hun eigen meetkastje hebben gesoldeerd. Als je kastje af is wordt hij geregistreerd en kun je hem bij jou thuis ophangen/neerzetten. Hierbij krijg je instructies zodat je de juiste locatie kunt kiezen en je metingen zo betrouwbaar mogelijk zijn. Als het dan eenmaal hangt kun je via de kaart op de [website van Meet Je Stad](https://meetjestad.net/index3.php?loc=Tb) bijhouden welke metingen je kastje neemt: zo kun je bijvoorbeeld zien op welke momenten het bij jou het warmst is en vergelijkingen maken met waardes van andere meetkastjes. Dat kan door middel van [deze tool](https://mjs-datavisualisation-fez7kynngq-ez.a.run.app/) die je helpt om grafieken te maken. Dan kan je er achter komen hoe jouw omgeving ervoor staat in vergelijking met de rest van de stad. Meet Je Stad organiseert ook kennisavonden met gastsprekers die vertellen over hitte, fijnstof en andere burgerinitiatieven in de stad. Dit zijn ook gelijk geschikte momenten voor deelnemers om met elkaar in discussie te gaan over hun metingen en ondervindingen. Zo hopen we een netwerk van betrokken inwoners te creëren en meer te weten te komen over de milieuomstandigheden in de stad! *\*De fijnstofsensor is optioneel en kost 20 euro extra. Indien je deze bij je meetkastje wilt moet je deze via een draad met een stroombron binnen 15 meter kunnen verbinden.* **Organisatie:** Milieucentrum Utrecht (MCU) in samenwerking met de Makerscommunity HaHaHo. **Locatie:** Bibliotheek Neude, Huis van Actief Burgerschap (begane grond) **Kosten:** 15 euro voor materiaalkosten, 20 euro extra voor fijnstofsensor. *Bij te weinig aanmeldingen kan de workshop afgelast worden.*

If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer. Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives. Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

Samen sporten, gewoon voor de fun, elke week een divers programma, met allerlei verschillende sporten. Je hoeft niet de beste te zijn, maar wel zin hebben om samen te spelen en te leren. Tijdens een training doen we verschillende spelletjes, basketbal, voetbal. volleybal, spikebal, honkbal. Kom je ook, de bal ligt bij jou!! Eerste keer meedoen is altijd gratis, daarna kan je beslissen of dit voor jou is, of niet!! Dus kom een keer proberen. Kan je niet op deze dag, we sporten ook op andere dagen nl Zondag om 9:30 of Maandag om 20:30 Stuur mij een berichtje als je op die dagen een keer wil proberen! The amount of people rsvp'd to this game doesn't match the real number of people at the event, as Meetup is only used for promotion purposes.

**Welcome to our February UX Beers in Antwerp!** This time, we will host our event on Tuesday the 24th of February with [Ariad](https://www.ariadgroup.com/en) at [Plein Magazijn](https://www.pleinmagazijn.be) in Antwerp.

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.

**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.
