Music Ensemble

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.

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.

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.

**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.

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!
