Extreme Programming

As a creative, you might recognise this: somehow you always end up with more craft and art supplies than you actually use. Maybe it was an idea you never got around to, maybe other materials just worked better, or maybe it was simply time for a good clear-out. Whatever the reason, those supplies deserve a second life! At this craft swap everyone brings the materials they no longer need. We put it all out on the table and from there it's up to you, browse around and take home whatever sparks your creativity. A fun and affordable way to find new supplies while helping each other free up some storage space. 🎨 It's also a great chance to chat with fellow crafters about what you like to make and get inspired by each other! * 🖊️ What can you bring? Think paper, pencils and markers, washi tape, beads, stickers, glue, wool, fabric, stamps, craft kits... basically anything craft-related that's been sitting unused * 📦 Anything unclaimed at the end of the evening you can take back home, donate yourself, or leave with the organiser who will pass it on to charity

This is a laid-back meetup for anyone interested in **functional programming**. The goal is to connect, share knowledge, and discuss FP concepts in a friendly environment. Bring your programs, questions, and topics to share—or just come by and be curious! I like Elm, Haskell, Swift, TypeScript, and Unison, but I’m open to other language suggestions. We gather on the 7th floor of OBA Oosterdok. Please find the organizer with Haskell/Elm/Unison stickers on a Mac. This meetup is still in an experimental phase, so the format and focus may evolve. Let’s see where it goes and build a great community together.

Join us for the next Azure Thursdays meetup. On **May 7th** we are welcomed by **Sopra Steria** at their Headquarters in **Nieuwegein**. **Confirmed speakers:** * Wesley Camargo (Tata Consultancy Services) * Jacco Rademaker (4Dotnet) **Program:** 17:30 \~ 18:00 Walk-in 18:00 \~ 18:45 Dinner 18:45 \~ 19:30 First session by Wesley - Your Azure Is Wrong And I Can Prove It 19:45 \~ 20:30 Second session by Jacco - The long running battle between Azure DevOps and GitHub: finally peace? 20:30 \~ 21:00 Drinks & wrap-up **Session 1:** *Speaker:* Wesley Camargo *Title:* Your Azure Is Wrong And I Can Prove It Many Azure environments are functioning, but that doesn’t mean they are designed to scale, stay secure, or meet enterprise requirements. Short-term decisions like using Resource Groups as environments, relying on a single subscription, manual scaling, and adding governance only when problems appear often lead to fragile platforms that break under growth. In this session, we uncover the most common Azure architectural anti-patterns and explain how the Microsoft Cloud Adoption Framework (CAF) provides a practical path from “it works” to Enterprise Ready. The focus is on the Ready, Govern, and Manage phases, where platform foundations are defined and long-term success is determined. You’ll get a clear overview of key CAF design areas, based on real production environments, not theory: • Identity and access • Networking • Governance and security • Monitoring • Automation • Cost management **Session 2:** *Speaker:* Jacco Rademaker *Title:* The long running battle between Azure DevOps and GitHub: finally peace? Are you currently working with Azure DevOps, but also have an eye on GitHub for its AI features? Do you need the functionalities Azure Boards offers and would you also like to use with AI agents? Or has your organization heavily invested in Azure Pipelines, which you do not want to rebuild using GitHub Actions? And when you would move your repositories, will you still have your pull request history? You do not have to go all-in with GitHub and leave Azure DevOps behind. Why choose, when you can combine them! You'll learn how to connect Azure DevOps to GitHub, what features this will open up for you and what your workflow can look like. This session will help you decide on how to move forward with your team or your whole organization! **About Azure Thursday and this event:** ===> Read more about the sessions and speakers on: www.azurethursday.com \# ==========CODE=OF=CONDUCT========== If you join this event, you agree with our Code of Conduct.

Not everyone who has ever worked in academia chooses to continue their career there. Sometimes academic work turns out not to be the right fit; sometimes it is simply different from what you expected. Some people entered with high ideals that did not come to fruition. Have you worked in an academic setting for at least one year (roughly full-time), and would you like to reflect on your experiences with others who have since left? Join the Journal of Trial and Error event on May 7, from 20:00, at Utrecht University Library City Center. During the evening, we will engage in an open dialogue. Together, we will explore what lessons the university can learn for improving science and higher education, and how these insights might help make academia more sustainable and appealing for the next generation.

Hallo liebe Java User Group Mitglieder! Diesmal haben wir Peter Kranz mit seinem interaktiven Talk zu den unterschiedlichen Java-Versionen zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 18:00 Uhr: Einlass * 18:30 Uhr: Talk * ab 19:30: Ausklang des Abends Dank an [adesso](https://www.adesso.de/de/unternehmen/standorte/nuernberg.jsp) für Location, Bier und Pizza! \-\-\- Java entwickelt sich seit Version 9 im Halbjahresrhythmus weiter – mit Records, Pattern Matching, Virtual Threads und vielen weiteren Features. Doch wer hat schon die Zeit, 17 Releases im Detail zu verfolgen? Die Fülle an Neuerungen ist enorm, und je nach Projekt und Interesse sind ganz unterschiedliche Features relevant. Ein klassischer Vortrag kann hier nur einen starren Pfad durch die Feature-Landschaft bieten. Dieser Talk geht einen anderen Weg: als interaktiver Dungeon Crawler. Das Publikum entscheidet gemeinsam, welchen Themenkomplex es als Nächstes erkunden will – Moderne Sprach-Features, Concurrency, APIs, JVM-Tooling oder experimentelle Preview-Features. Jede Entscheidung führt tiefer in den Dungeon und schaltet neue Level frei. So entsteht bei jedem Vortrag ein einzigartiger Pfad durch die Java-Versionen 9 bis 26. Wie in einem echten Dungeon Crawler sammelt das Publikum dabei XP und wird am Ende einer Klasse zugeordnet – vom Warrior mit Fokus auf Performance bis zum Wizard der Sprach-Features. Ob Einsteiger:in oder erfahrene:r Entwickler:in: Jede Session liefert praxisnahe Einblicke in genau die Java-Features, die das Publikum am meisten interessieren. Kein Vortrag gleicht dem anderen – und der einzige Weg, alles zu sehen, ist wiederzukommen. \-\-\- Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

For our next hike we'll be following a beautiful 9.5km route starting at Soest-Zuid train station and ending at Amersfoort Central Station. On the way we'll pass by the Soesterduinen dunes and the Birkhoven forest. Will you join? Utrecht Hiking Community aims to organise one hike per month in the Utrecht Region. Anyone is welcome to join, no matter whether you're a beginner or an experienced hiker, a local or an expat, a professional or a student, as long as you bring a good mood. We are not about fast hiking, but about social hiking: being active, exploring places, meeting like-minded people and just generally having a fun walk. We'll be starting from Soest-Zuid train station at 10.30AM. This time we won't be following a circular route, which means we won't end at our starting point, but we'll end at Amersfoort Central Station instead. Those who want to return to Soest-Zuid station afterwards to get back to their car, can take bus 70 from Amersfoort, which is going every 15 minutes. Please try to arrive to Soest-Zuid on time. We'll start our hike at 10.30AM and won't let the whole group wait for you in case you're arriving later. Only in case the train scheduled to arrive at 10.24AM has some delay, we'll wait for that train to arrive. If you're arriving after we have departed, you can send a message on WhatsApp to +31621177691, so we can share our location with you and you can try to catch up with us. Soest-Zuid station has a toilet, but please don't count on it to work. When checking the route, it was closed. On the way there are no public toilets, so please use a restroom before you arrive. The route is going over both paved and unpaved roads and we'll even be walking through the sand of the Soesterduinen dunes for a bit (not for long, as it's harder to walk through the sand than on the paths). Please wear good shoes, bring something to drink for on the way and use SPF if it'll be a sunny day Dogs are allowed on the route, but need to be kept on a leash on parts of the route. After the walk, those who want can join for lunch/drinks in the center of Amersfoort. This is not directly next to Amersfoort Central Station, but at a distance of another 15-20 minutes of walking. Since we do make some costs while organising our hikes (MeetUp subscription, travel expenses), a small donation would be very much appreciated. You can do so by following this link: https://www.ing.nl/payreq/m/?trxid=s9tT34cUyD97YuSHhIYbTIqN4LfxLAn9 If you have any questions, please feel free to ask. See you on Saturday 9th of May at Soest-Zuid train station!

Come play improv theatre in English and kick off your Friday evening with laughter, creativity and new people. This [drop-in workshop](https://www.improvutrecht.nl/drop-in-workshops/) is open to everyone, whether you are trying improv for the very first time or you have played before and want to stay sharp. You do not need acting experience and you do not need perfect English. Many people join us for the first time each week, alongside regular players who keep coming back. The atmosphere is open, playful and supportive, with a real focus on having fun together. During the session you can expect: * Meeting internationals and Dutch players who enjoy playing in English * Fun and accessible improv games inspired by shows like Whose Line Is It Anyway and De Lama’s * Clear introductions to improv principles like listening, accepting ideas and playing together * Plenty of laughter and a few moments where you surprise yourself * A relaxed, social vibe rather than anything competitive or performative We play from 20:00 to 22:00. Doors open between 19:50 and 20:00 and you enter together via the side entrance on Troelstralaan. After the workshop, many people head to O’Leary’s nearby for a drink and a chat. Sign up by adding your name via [https://bit.ly/iudropin](https://l.facebook.com/l.php?u=https%3A%2F%2Fbit.ly%2Fiudropin%3Ffbclid%3DIwZXh0bgNhZW0CMTAAYnJpZBExYzVUWUpNcUx3Qmxyc0tCNnNydGMGYXBwX2lkEDIyMjAzOTE3ODgyMDA4OTIAAR5K0FVPivgkRn67BEoDofHkr7Es12_1bq4hDCggWDXNdpNhLZnzLNMNtrNdqw_aem_j1YiiuZaWNnyDZ5jbnCCBQ&h=AT2fpKsMMORdusQhpZ9iv0ed8772wQ5kPJcHxIGz5i8iQEJK0FVlSpqVqEh62oBzSisT7moNRPBSDvWIuZEL9WgLIXRbLyqXfXj7sE7CYyKbKxqnakD0W31HOEXSgK_5tuPYJFStscaUvrh-0pc&__tn__=q&c%5B0%5D=AT3WQkDUYF4F66VuKR4XhsJ2afRvpjsAkK93Octb-hRh_JIzYk-7ePG7XSFfHFYxd9GLxqQgCwnPjN2yiYBNVADfb7VXyjFO1sHIArS4Jo43x4NQHr-b2RMtZUH_TIvYncgegRNFx3P2HDQbu5bCg5dzFhmaWlgHFa4). If you can no longer attend, please remember to remove yourself so someone else can join. The workshop works on a Pay What You Thought It Was Worth basis. Suggested donation is €10 to €20, but you are always welcome regardless of what you can pay. Contributions help cover the room and the professional trainer giving up their Friday evening. **About the teacher this week** This session is taught by [Steven Morgan](https://stevenmorgan.wales). Steven is a British comedian, improviser and teacher with a long international track record both on stage and in the classroom. He was the Head of Teaching at easylaughs in Amsterdam and was cast member of Impro Amsterdam for two years running. He previously organised the Bris Funny Fest in Australia, producing over one hundred comedy shows, and has performed stand up comedy in numerous countries and festivals including the Utrecht International Comedy Festival. Steven has also run corporate workshops for organisations such as Nike, Zoom and the Red Cross, and was one half of the improv duo Tru2U with Rogier Bak. His teaching style is playful, clear and confidence building, with a strong focus on connection, generosity on stage and enjoying the moment rather than trying to be funny. Whether you come to learn, to meet people, or just to have a joyful Friday evening, you are very welcome.
