Because resilience isn’t just about having backups—it’s about knowing they work. **Talk 2:** What happens after an innovation delivers a promising platform before it’s ready for enterprise scale, governance, and speed? That’s where our journey begins. You’ll hear how we evolved the architecture to support over 100 microservices powering digital lending on a compliant-by-design AWS environment. We’ll share the decisions we made along the way: what we kept and what we changed. Central to our approach is Infrastructure as Code to enable consistency, repeatability, and control on the platform. We’ll show how this foundation helped us automate operations, accelerate delivery, and meet strict compliance requirements. Join us to learn how to bridge the gap between innovation and enterprise readiness, turning a promising start into a scalable, secure, and developer-friendly platform. **Talk 3:** EDSN acts as the digital backbone of the energy market, supporting essential data exchange processes across the energy market value chain. We explore this role, the underlying IT foundation, and the challenges and trade-offs that come with it.

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. (Meet-up suggereert bij het aanmaken van een account dat een betaald abonnement vereist is. Dit is niet zo, op de pagina waar gevraagd wordt om een abonnement te kiezen staat rechts bovenin de optie "Ga door met het gratis plan".) *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.

'THE SYMPATHIZER' by Viet Thanh Nguyen 'The winner of the 2016 Pulitzer Prize for Fiction, as well as seven other awards, The Sympathizer is the breakthrough novel of the year. With the pace and suspense of a thriller and prose that has been compared to Graham Greene and Saul Bellow, The Sympathizer is a sweeping epic of love and betrayal. The narrator, a communist double agent, is a man of two minds, a half-French, half-Vietnamese army captain who arranges to come to America after the Fall of Saigon, and while building a new life with other Vietnamese refugees in Los Angeles is secretly reporting back to his communist superiors in Vietnam. The Sympathizer is a blistering exploration of identity and America, a gripping espionage novel, and a powerful story of love and friendship.' ***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.

**Welcome to our June UX Beers in Antwerp!** This time, we will host our event on Tuesday the 30th of June at Craftzing in Antwerp. [Ariad](https://www.ariadgroup.com/) and [Creative Skills](https://www.creativeskills.be/) sponsor our events. Follow the event online? We stream live via [Youtube](https://www.youtube.com/watch?v=EBqyTDAyQBw) \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# UX TALKS **Talk 1:** **UX with AI: Did we all just get promoted?** By An-Sofie Rombouts, Product designer @ Gorilla Working in a startup often means designing without established UX processes. So with AI emerging, it can feel like a lifeline: faster prototyping, '*deeper*' research, and more concepts to explore. But somewhere between the third AI-generated prototype and losing the thread of your prompted designs, it can become painfully obvious what the impact is of designing with LLMs. We're not executing anymore, we're reviewing, approving, and critiquing, like a manager. This talk gets honest about what that actually means: the speed gains are real, but the cognitive debt is quietly compounding, and your future as a designer depends on understanding why. Explore how designers can protect their cognitive depth, enhance their review capacity, and stay in control when the machine can almost draw anything. **Talk 2:** **Growing UX in organisations that are not there yet.** By Koen Peters, Designer at Namahn More and more organisations are asking us to help build design expertise in-house, even putting together a design team for them. I have learnt that in such cases, you need to set aside your own biases and assumptions first: your neatly mapped-out methodology, your Figma dogmas and all the other things you as a design agency take for granted. The reality in these organisations is often very different: limited resources, no design culture and few or no trained designers on the team. Through a few client case studies, I will show how we have tackled such challenges. Organising a training in UX and design thinking is a good first step, offering a chance to get to know the team and identify which skills are already there and which are missing. I will also demonstrate tools and activities that we have used to help a team get started and become more aware of UX research and design. These include a script for choosing the right UX approach, skills assessment models to identify gaps and first steps towards creating a design playbook. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

De *veertigste* monthly meetup van [Nimma.codes](https://www.nimma.codes/) alweer! We zijn een cross-language user group voor software developers in de regio Arnhem-Nijmegen en komen elke laatste dinsdag van de maand samen om te praten over alles wat met software development te maken heeft. Wees welkom! (ook als je niet programmeert) *Ditmaal zijn we wederom te gast bij Deftpower [Clean Tech Park Arnhem](https://cleantechparkarnhem.nl/).* **Programma** * **17:30 – 18:00** Inloop + food & drinks * **18:00 – 18:45** Talk 1: [Tim Steenvoorden](https://github.com/timjs) \- De lambda calculus in moderne programmeertalen * **18:45– 19:00** Pauze * **19:00 – 19:45** Talk 2: [Deftpower](https://www.deftpower.com/) - [William van der Vegt](https://vegt.dev/) \- Van thuislaadpaal naar actor: kennismaken met schaalbaar sessiebeheer in \.NET Orleans * **20:00 - 21:00** Netwerken **Talk 1: Tim Steenvoorden (Open Universiteit en Radboud Universiteit) - De lambda calculus in moderne programmeertalen** Eén herschrijfregel, geen types, geen geheugen, geen loops. In 1936 definieerde Alonzo Church een rekenmodel van bijna irritante eenvoud die toch even krachtig is als een Turingmachine: de lambda calculus. Deze sessie is een reis van die wiskundige kern naar de code die je dagelijks schrijft. We beginnen met pen en papier: lambda termen lezen, schrijven en reduceren. We gebruiken niets anders dan functies voor het bouwen van datastructuren. Vervolgens maken we de vertaalslag naar closures, higher-order functions, immutability en pipelines in talen als Java(Script), Python, Kotlin, Haskell en Rust. Het doel is niet om morgen anders te programmeren. Het doel is om te begrijpen waarom moderne talen de afgelopen decennia steeds meer functionele concepten hebben overgenomen en wat de gemeenschappelijke wortel daarvan is. **Talk 2: Deftpower - William van der Vegt - Van thuislaadpaal naar actor: kennismaken met schaalbaar sessiebeheer in .NET Orleans** Ik ben van kleins af aan een echte techfanaat; thuis hobby ik met gadgets, servers en frameworks. Sinds een klein half jaar werk ik bij Deftpower, waar bedrijf, sector én techstack perfect bij me passen. Daarvoor vijf jaar bij Info Support, vooral voor de klanten Air Miles en Moba. Vanuit die liefde voor tech vertel ik wat over .NET Orleans: het framework waarmee we bij Deftpower duizenden thuislaadpalen tegelijk beheren. Duizenden live, stateful verbindingen, elk met hun eigen sessie en toestand. In klassiek .NET loop je dan al snel tegen locks en race conditions aan. In deze talk laat ik zien hoe we elke laadpaal als een actor modelleren met .NET Orleans, en zo schaalbaar bouwen zonder grote concurrency issues. Inclusief een praktische kennismaking met het actor-model, voorkennis van Orleans is niet nodig. **Locatie** [Clean Tech Park Arnhem - Connector gebouw KB - 1ste verdieping.](https://maps.app.goo.gl/VcFWRSbF5fT6J2PB7)

The Dutch Heuvelrug is a hilly and sandy ridge, running from Hilversum in the north to Rhenen in the south. This National Park is covered in forest, heather and stretches of sand and dunes. On this hike, we will explore the Heuvelrug from Den Dolder. This area is mostly forested, perfect for a (hot) summer’s day! **Where to meet**: we will meet at **10 am** at train station Den Dolder. We will return to the same train station around 3pm. **This hike is fully booked.** [You may register on my website for a place on the waitlist.](https://rewildyourself.nu/dutch-nature-hikes/)

We’ve all had it: going blank mid-sentence, a tight chest before a hard conversation, or that strange emptiness right after finally getting what we wanted. This first gathering is a chance to slow down and actually listen to what your body’s been holding. For this session, we’ll explore the question together: what is your body trying to tell you? Through a short opening round, gentle orientation, and guided somatic practice, you’ll get a real feel for what Somatic Circle is about — not theory, but actual practice. What to expect: 🗣️ A short opening round — a few words on how you’re arriving 🧭 A brief framing of the theme 🌀 Guided somatic practice — breath, presence, and gentle inquiry 💬 Space to reflect and share, if you want to It is a free event!

BACK TO CABS!!! Come to CABS Friday 7/10 & Saturday 7/11 - return to CABS as we come back from Origins and the 4th of July Holiday Break. Come play the new games added to the library at Origins!!!

Join us at Unity of Columbus for our Weekly Reiki Share, a peaceful and uplifting gathering for connection, healing, and growth. A Reiki Share is a time where Reiki practitioners and students come together to give and receive healing energy in a supportive and welcoming environment. These sessions will be moderated by Columbus Unity Reiki. Reiki is a hands-on energy healing method from Japan that first came to the United States in 1938. Since then, it has grown in popularity and is now widely practiced throughout the West. All levels are welcome, and you do not need to be a practitioner at Unity of Columbus to attend. If you are a Reiki practitioner, a Reiki student, or simply interested in becoming a Reiki student, we warmly invite you to join us. Come practice your healing techniques, learn new approaches, receive healing energy, and connect with a like-minded community in a space of relaxation, renewal, and positive energy.

Short North Street Skates return Saturday, April 4 and we’re excited to get back rolling together. These weekly rollouts are a chance to move through the city as a group, build community, and create more visibility for skating and small-wheeled movement in Columbus. Details: Meet: 1160 N High St 9:30 AM meet 10:00 AM rollout All wheels welcome We’ll be skating through the Short North and surrounding areas at a steady, social pace. Routes will use a mix of streets and bike lanes, so comfort navigating the city is helpful, but you don’t need to be an expert. If you’ve been meaning to come out, this is a great place to start. Come solo or bring a friend!
