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.

## Connect & Grow onder begeleiding van Pauline van Aken, auteur, spreker en trainer... ## Voel je dat je hoofd vaak te “vol” zit en heb je behoefte aan meer rust én echte gevoelsmensen om je heen in de natuur? ## Tijdens deze 1e Connect & Grow sessie, stap je even uit de drukte van alledag en kom je samen met een groep bewuste en gelijkgestemden. Een laagdrempelige, ontspannen meeting waarbij je kunt 'zijn' en we ook, als het weer het toelaat, een mooie wandeling maken. We ont-moeten, verbinden en doen tussentijdse korte, praktische oefeningen, waarbij je voelt dat je hoofd even met 'vakantie' is. De meeting vindt plaats in de natuur bij de Hoorneboegse Heide. Specifieke meetingpoint: Brasserie Zonnestraal op de parkeerplaats rechts van de zij ingang. Bij minder goed weer verzamelen we binnen in de Brasserie Zonnestraal. Wil je hierbij zijn, stuur dan een mailtje met je naam en mobiele nummer + de datum (zaterdag 9 mei) naar: info@paulinevanaken.nl Check ook even de site: Paulinevanaken.nl zodat je weet hoe ik eruit zie en wellicht kan ik je alvast inspireren met wat ik deel in verschillende podcasts en blogs. De kosten: €27,00 p.p. inclusief 't boek: VOEL, *terug in contact met jezelf,* exclusief drankjes en versnaperingen die bij de Brasserie mogelijk zijn om te bestellen. Ik kijk ernaar uit je te ontmoeten. Lieve groet, Pauline

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!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
