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.

This is a new edition of the Socrates cafe with a new format. In this edition, the moderator will pick a specific quote, topic or question from a known philosophers (example; Voltaire, Kant, Marcus Aurelius, Hypatia of Alexandria, Rousseau, Machiavelli, Descartes, Plato and others). A summary around a page will be provided in the event *(**See below - The topic of this Session)*** Please take the time to read. The Moderator will read the summary and give an introduction of the topic. Then, we will have an open discussion, and a final round when everyone will give their conclusions. **The topic of this Session** **Søren Kierkegaard** (1813–1855) was a Danish philosopher, theologian, and writer often considered the father of existentialism. He focused on the individual’s experience of freedom, anxiety, faith, and the search for meaning in life. Kierkegaard argued that truth is subjective and must be lived personally rather than accepted abstractly. His work deeply influenced existentialist thinkers and modern philosophy. **Søren Kierkegaard -** *“Truth is not something you can inherit or learn. Truth is something you must discover yourself,”* Søren Kierkegaard’s quote means that truth isn’t just about facts or inherited beliefs—it’s a personal, lived experience. * **Not just knowledge:** You can’t truly understand truth by just reading or being told—you must engage with it yourself through your choices, struggles, and experiences. * * **Subjective and active:** Truth requires personal commitment—like faith, love, or morality—where you live it, not just believe it. * * **Rejects passive acceptance:** Kierkegaard critiques blindly following tradition or authority. Real truth comes from your own journey of doubt, reflection, and action. * **In short:** Truth is authentic only when you discover and embody it yourself. **About the Philosopher** https://www.britannica.com/biography/Soren-Kierkegaard **RULES** 1. Please be on time! We will start at 19:00 so if you arrive late, please join quietly. If you are a first timer, make sure you take extra time for finding the location. 2.

**ArnhemJUG** We are excited to announce that we are welcomed by Avisi for the March meetup. **Agenda** * 17:00 CET walk-in * 17:30 – 18:30 Food and drinks * 18:30 – 19:30 talk: **Koog your own AI! Delicious recipes** by **Simon Vergauwen** * 19:30 – 19:45 break * 19:45 – 20:45 talk: **Domain-Driven Design** by **Dirk Groot** * 20:45 – 21:30 drinks **Koog your own AI! Delicious recipes** Koog is an open-source Kotlin framework for building robust, and production-ready AI agents. Developed, and battle-tested in their own products by JetBrains! In this session we’ll build an agent, and explore various techniques to tackle different kinds of problems, and complexity. How we can use model-context protocol (MCP) to give our agent access to external tools, and how to build custom tools to integrate with your own systems. How to define flexible graph workflows to design complex agent behaviors. If you're not cooking your own AI Agents yet, you should! Join me and I’ll give you a taste of Koog. **About** **Simon Vergauwen** **Developer Advocate at JetBrains & OSS (arrow-kt) Maintainer** **Software engineer from Antwerp, Belgium.** Interested in everything functional, and Kotlin. Loves OSS, cooking, snowboarding and Fallou **Domain-Driven Design** What name should I give this entity? How should I deal with ambiguous terminology? Where should business rules be implemented? Is this validation part of the domain logic, or does it belong to the application layer? Which entities should be within the scope of this database transaction? In this talk we explore how the **Domain-Driven Design (DDD)** methodology helps answer questions like these. We will cover the key DDD concepts, including **Ubiquitous Language**, **Bounded Context**, **Aggregates**, **Entities**, and **Value Objects**, and discuss how they fit within a software architecture. The session is built around a practical example, so you will not only learn the theory behind DDD, but also see how these concepts can be applied in real-world software development. **About Dirk Groot** I'm a software engineer with more than 25 years of experience. Since my early teens, sofware engineering has been my greatest passion.

**Um was geht es dieses mal?** Dieses Mal haben wir zwei Talks für euch! **Performance und Portability in Data Analytics mit DuckDB & Co. - Niklas Niggemann** Moderne Data Teams kämpfen mit zwei Kernproblemen: Performance und Portability. Dieser Vortrag zeigt anhand umfassender Benchmarks von DuckDB, Polars und Pandas mit Datensätzen von wenigen Gigabyte bis zu mehreren Terabyte, wie Ausführungsmodelle, Dateiorganisation und Speicherverwaltung die Performance beeinflussen. DuckDB liefert konstant niedrigen Speicherverbrauch, Polars erreicht durch Parallelisierung hohe Geschwindigkeiten – doch sobald mehrere Engines „schnell genug" sind, zählt Flexibilität. Abschließend zeigen wir deswegen, wie Frameworks wie Ibis die analytische Logik von Engines entkoppeln und so lokale Entwicklung, Cloud-Deployment und Plattform-Migrationen ohne teure Neuentwicklungen ermöglichen. **Design Patterns - Wie sie dir helfen, ausdrucksstärkeren Code zu schreiben - Christian Ambach** Vor über 30 Jahren veröffentlichte die Gang-of-Four ihren Klassiker "Design Patterns. Elements of Reusable Object-Oriented Software". Viele der Muster erfreuen sich heute großer Beliebtheit und es sind eine Menge von Patterns dazugekommen, nicht nur auf Design-, sondern auch auf Architektur- und Organisationsebene. Wusstest Du, dass Du wahrscheinlich schon Design Patterns einsetzt, ohne es zu merken?In diesem Vortrag wird betrachtet, wie bekannte Frameworks und Bibliotheken – zum Beispiel das Spring Framework – auf Design Patterns setzen und wie die Teilnehmer diese Muster vielleicht schon ganz selbstverständlich in ihrem Code verwenden. Gemeinsam werfen wir einen Blick auf eine Auswahl von Design- und Architekturpatterns, entdecken Good und Bad-Practices und wie man Patterns gezielt einsetzen kann, um Code noch ausdrucksstärker zu machen. **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben. Den Live-Stream findet ihr auf dem [YouTube-Channel ](https://www.youtube.com/@codecentricAG)der codecentric AG. **Wichtig - Absage bitte rechtzeitig:** Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis! **Anreise:** Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß. Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

**DDSCC Meetup 7** 📅 **Datum:** Vrijdag 27 Maart 2026 🕐 **Tijd:** 12:30 – 17:00 📍 **Locatie:** Rubicon Cloud Advisor, Leusderend 36, 3832 RC, Leusden **Wat kun je verwachten?** **Agenda** * 12:30 – Inloop met koffie en lunch * 13:30 – Opening door DDSCC * 13:45 – Introductie door Rubicon Cloud Advisor * 14:00 – Jasper Oosterveld: With Great Power Comes Great Labeling: Sensitivity Labels in de Praktijk * 14:45 – Pauze * 15:15 – *Jeroen Bijdevier:* Je omgeving op orde voor veilig en optimaal Copilot gebruik * 16:00 – Ronde tafel gesprekken * 16:30 – Borrel & netwerken (tot 17:00 uur) **Session description:** **Jasper Oosterveld - With Great Power Comes Great Labeling: Sensitivity Labels in de Praktijk** Veel organisaties hebben inmiddels sensitivity labels geïmplementeerd als basis voor data security in Microsoft 365. Maar zodra je voorbij de basis komt, ontstaan er nieuwe vragen. Hoe ontwerp je een werkbaar labelmodel? Hoe voorkom je dat gebruikers verdwalen in te veel labels? Wat betekent labeling voor Teams, SharePoint, Data Lifecycle Management en Microsoft 365 Copilot? En waarom gedraagt het platform zich soms nét anders dan je verwacht? Tijdens deze interactieve sessie deel ik mijn praktijkervaringen met sensitivity labels: keuzes die goed uitpakten, dingen die ik achteraf anders zou doen en de frustraties die je alleen tegenkomt wanneer je labels écht gaat gebruiken in productie. Dit is nadrukkelijk geen theoretische sessie. Neem je eigen ervaringen, uitdagingen en meningen mee, zodat we samen praktijklessen kunnen uitwisselen en ontdekken hoe we sensitivity labels effectiever kunnen inzetten. **Jeroen Bijdevier - Je omgeving op orde voor veilig en optimaal Copilot gebruik** Copilot ziet het verschil tussen achterhaalde en recente informatie niet. Die zal je dus een beetje moeten helpen. Rechten zijn vaak niet (in detail) op orde. Manueel deze zaken vinden is lastig en tijdrovend. Natuurlijk wil je rapportages hebben van het gebruik. Ergo dataveiligheid op orde en inzicht in het gebruik met Purview.

🏔️ Everest Update for the Veluwe Power Hikers We were preparing for a classic VPH high altitude expedition on top of the world. Unfortunately there is some disappointing news. Starting in 2026, Nepal is introducing strict new regulations for climbing Mount Everest. Climbers will now need to have previously summited a 7,000 meter peak in Nepal and must also submit mandatory health certificates. Because we cannot realistically summit a 7,000 meter peak and then climb Everest on the same day during our hike, I am unfortunately obliged to change the program. There is also another small complication. 1 April falls on a Wednesday, which makes organizing the expedition a bit difficult. After a poll in the WhatsApp group, we decided to move the date to **28 March** and climb the highest point of the Veluwe, **Signaal Imbosch (110 m)**. Even if it’s not Everest, don’t underestimate this hike: we will cover **22 km with about 350 metres of elevation gain** at a brisk pace. At this altitude, however, oxygen bottles are no longer recommended. Please update your RSVP if you can no longer attend due to the change. ⛰️🥾 **When and Where to Meet?** 10:10 sharp at Rheden Trainstation. ⏰ Please arrive on time, as we won’t be able to wait for latecomers. 🥾✨ https://maps.app.goo.gl/VaEtswyBps5awMoL7 **Where and When Shall We Rest?** We’ll take 2 breaks: * Lunch break in nature at Signaal Imbosch (110 m) with group photo on summit; 20 min * Snack and drink at Basecamp (80 m) where you can buy drinks and snacks; 30 min **Notifications:** * Technical equipment: avalanche transceiver (beacon), avalanche probe, and avalanche shovel (if you have them) * A compact lunch and water to share at the summit * The hike will only be canceled in case of severe avalanche risk (code 5). * If you plan to bring a companion, please ensure that they are also registered for the hike. * To be the first to get updates on new hikes, join our WhatsApp group! Feel free to ask for the QR code during the hike to easily join. * T-shirts are now available for €25, made from Fairwear-certified organic cotton with eco-friendly inks—sustainable, odor-resistant, and perfect for your hiking adventures (limited stock, available during the hike)! Let me know your size and I will bring one for you!

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!
