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, Collegezaal (2e verdieping) **Kosten:** 15 euro voor materiaalkosten, 20 euro extra voor fijnstofsensor. *Bij te weinig aanmeldingen kan de workshop afgelast worden.*

**This will be a Hybrid event, where we'll be in person at CGI (used to be BJSS) on King Street Nottingham, and online on Zoom.** **C# in the browser: An intro to Blazor and WebAssembly - Adam Blakey** Everyone knows that JavaScript is baked into all modern browsers, but what if you wanted to build rich, interactive web apps that ran C# code directly in the browser? In this talk we'll explore Blazor, Microsoft's framework for building web apps with .NET, and how it can leverage WebAssembly to run C# directly in the browser. Adam will take you through what Blazor is and the types of hosting models available, and what WebAssembly is and how it differs from traditional JavaScript-based approaches. Finally, we'll finish with some interactive demos showing the power of Blazor and WebAssembly. **Our Speaker:** **Adam Blakey:** 💼**Adam is a Graduate Software Engineer at Capital One.** Before this, he worked at Savoy Systems on projects ranging from data visualisation and automated testing to a major initiative involving porting a legacy application to a new language. 🧑‍🔬 **In 2024, Adam completed his Mathematics PhD at the University of Nottingham**, where he developed scientific software to simulate blood flow and nutrient transport within the human placenta. 🧑‍💻 **Most of Adam’s work centres on software development**, and in his spare time he predominantly creates websites and bespoke software in PHP, SQL, JavaScript, HTML, and CSS. He has substantial experience with an eclectic mix of C#, Delphi, Fortran, Java, PHP, and Python, and he has independently taught a first‑year undergraduate Python course at the University of Nottingham. ✅ **Adam has spent many years as a trustee of three local charities**, served on committees for three additional organisations, and has volunteered weekly with Scouts since 2015.

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.

We’re heading into the south eastern Veluwe for a stunning scenic route that stays wonderfully quiet and almost deserted for a big part of the way, before building up to a truly spectacular grand finale! After around 6 km we reach the mysterious “Altar of the Loenermark” (Altaar van de Loenermark). I have no idea what it is, so we’ll discover it together. From there we continue through the beautiful heather and forest landscapes of Loenermark, one of those places where the Veluwe feels wide, wild, and open. Next we pass one of the quirkiest monuments in the Netherlands: the Ijkbasis Loenermark 1957–2007, a tribute to the calibration of measurement instruments from the past. The calibration itself might not sound exciting, but the location absolutely is, right in the middle of wide open heather, with big skies and that endless Veluwe feeling. It also marks about 11 km into the hike, a perfect spot to take our lunch break. After lunch we walk straight through the iconic National Park Veluwezoom, famous for its rolling grasslands and its fluffy semi wild cows. To finish in style, we end at Paviljoen De Posbank for a well earned snack or drink with a view over what many call the most spectacular heather of the Netherlands, complete with rolling hills. From there we head down towards Rheden, where you can easily catch the train or bus home. This is not a loop hike! **📍When and where to meet?** We’ll meet at 10h at busstop Loenen, Leeuwenbergweg. https://maps.app.goo.gl/LC3nNJQo57B5NnSy8 We are leaving a bit earlier otherwise we will find Paviljoen Posbank closed, which would be very sad. ⏰ We **start walking a few minutes after meeting up** — we don’t wait for latecomers, as the forest calls and daylight is short this time of year. **🚗 Coming by car?** This is not a loop hike. If you park in Loenen, you’ll need to make your own way back from Rheden afterwards. **⏸️ Planned Breaks** After **11 km**: Lunch break at **Ijkbasis Loenermark** (bring your packed lunch, this spot is truly in the middle of nowhere) **20 min** [https://maps.app.goo.gl/S5vAEpadAJs93ZrC7](https://maps.app.goo.gl/S5vAEpadAJs93ZrC7) After **19 km**: Snack or drink at **Paviljoen De Posbank** [https://maps.app.goo.gl/wowuqj3sRY5hcid37](https://maps.app.goo.gl/wowuqj3sRY5hcid37) **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list. If there’s a waiting list, this will happen sooner (in less than 48 hours). If that happens, no worries — you’re always welcome to sign up again if there’s space. 🌟 Early Bird Deal! Join now for just €4 — available for 3 days (72h). After that, the price will be €5. https://tikkie.me/pay/59muhp2djpv45gc6hgh6 **👟 Good to know** * Refund policy: Cancellations are fully refundable up to 1 week before the event (This is Friday 23 January at 23h59). After this period, the fee becomes non-refundable. * Hike difficulty: Our hikes are moderately challenging. Please only join if you’re confident you can keep up with the group’s pace (5 km/ h)— it’s more fun for everyone when we can walk together without long waits. * If the pace is too challenging: We may kindly suggest you continue at your own pace. We’ll give you clear directions to the nearest bus or train so you can return comfortably. * At your own risk: You participate at your own risk, so please make sure you have appropriate insurance coverage for outdoor activities. * Payment note: With Tikkie we only see initials (e.g., J. Doe instead of John Doe). Please include your Meetup name in the payment note so we can match it easily. * Friends joining: If you bring a friend, make sure they also register and pay. * What to bring: Snacks, lunch, and water/ or hot thee/ coffee. * Stay connected: Join our WhatsApp group to be the first to hear about future hikes — ask for the QR code during the hike. * T-shirts: Fairwear-certified organic cotton, eco-friendly inks — €25. Sustainable, odor-resistant, and perfect for hiking. Let us know your size and we’ll bring one for you.

Hi ladies. Let's hike the multi-purpose trail - approximately 4 miles. Meet in the Maple Grove Picnic area.

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development
