Eric Seppanen will host a workshop to create your own rusty logo, using home chemistry to turn shiny steel into an oxidized work of art. Note: it will take an extra day for the finish to dry, so please ensure you will be around to pick up your rusty logo the next day. This workshop is held at Kinepolis (the conference venue) and is free of charge for RustWeek attendees. Looking for more fun things to do during RustWeek?

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.*

Please join us for an evening of all things Umbraco - the latest news, community chat, and a talk or two! For 2026, we will be running both in-person and virtual meetups, alternating every month. For those who can't join in person, virtual attendance is available too, so you can join us no matter where you are! This month, we have **Owain Jones** talking about building friendly content editing experiences and **Markus Johansson** talking about building packages for Umbraco. **Owain Jones - Unlocking the Full Potential of Umbraco: Building Friendly Content Editor Experiences** Umbraco is often called "The Friendly CMS", and it absolutely can be when we, as developers, make the most of what it offers. In this talk, I’ll show how we can utilise Umbraco’s built-in features and community packages to build intuitive, efficient, and friendly experiences for content editors. **Markus Johansson - Extending Umbraco like a Swede** In this talk, Markus will share his learnings from over 15 years of extending Umbraco. We’ll get a brief overview of the possibilities introduced with the new backoffice “Bellissima”. He’ll also give us tips and tricks that is useful both when extending Umbraco for a specific project or publishing a package for the Umbraco Marketplace. There will also be food, drinks and some friendly socialising. What's not to like? 😄 Whether you are an Umbraco novice or a seasoned developer, this is your chance to meet like-minded people to talk about our favourite friendly CMS! No matter what your role is there will be something to learn and your chance to meet other members of the Umbraco community from Kent and the surrounding areas. Venue The meetup will be at Dragon Coworking in Rochester (7-8 New Road Avenue, St George's Hotel, Rochester, ME4 6BB), a short walk from Chatham train station and with free on-site parking. If you wish to use the car park, please access via Gundulph Road, Rochester, ME4 4ED. You can then use the steps between buildings to access the entrance.

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.

She knows the challenges that UX teams face in demonstrating their added value from her 10+ years of experience at the tech start-up Blendle, cybersecurity scale-up Zivver, and low-code SaaS Mendix. She now helps teams with gaining a competitive edge through inclusive research and co-creation “from a to y”. Her talk will point you to the importance of user experiences that are not reflected in the training data of LLMs and the “curb cut”-effects to be gained which no synthetic persona will provide. **Speaker 3: Bo Kusters** Service Designer at the Dutch Tax Administration. With millions of users, the team often sees the same generic functional and emotional needs recurring in their user research. To avoid reinventing the wheel every time, they developed an interactive, tarot-style card game. With this clever deck, they make complex user insights tangible, allowing internal teams to apply this data directly in their daily work. Learn during this session how to successfully translate abstract research data into a practical design tool that actually works for your team. **Event details** **When:** May 21 \| 18:30 – 22:00 **Where:** Acato, Oudegracht 231, Utrecht **Cost:** Free \(Includes snacks & drinks sponsored by Visma \| ProActive\) **Capacity:** 50 spots Stay tuned for more updates!

Come along, lovely queer hikers! 🌿✨ This time we’re serving an easy-going queer nature moment with a short loop through **Landgoed Heidestein** near Zeist. Think dreamy forest paths, shimmering fens, a peaceful forest pond, and heather fields - a lot of diversity for such a short walk :) We’re teaming up with **Cocktail (COC’s group for LGBTQIA+ refugees & asylum seekers)** for this event, so besides soaking up nature, we’re creating space for connection, sharing stories, and learning from each other’s journeys and experiences. Expect a vibe that’s part hike, part picknick, part wholesome community exchange. 🌈 Bring your snacks and blankets, as we’ll pause along the way for a relaxed picnic moment together. Because queer joy isn’t just about where we go, but who we walk with. 💖 **Practical info** 📏 **Distance:** 5 or 7 km (loop walk) 📍 **Start:** Bus stop Prinses Margrietlaan, Zeist (5km option) Driebergen-Zeist station (7km option) 🏁 **End:** Back at the starting point 🥾 **Level:** easy - chill pace 🤝 **Meeting point:** outside the train station **Driebergen-Zeist at 13:45** or bus stop **Prinses Margrietlaan (Zeist) at 14:20** ❗You’re welcome to join from another direction.

## Love is in the air…! Experiencing dating burnout? You're not alone. If you like deep conversations and are finally ready to get out and meet people irl, you've come to the right place! **No more swiping, skip the bad dates!** Due to the increasing size of our waiting list, and as per your frequent requests, this is our answer to you with a second event within Utrecht this May! ### *This is how it works:* * Before you arrive at the meetup, you fill in a fun 5-10 minute questionnaire on [affinitee.eu](https://affinitee.eu/au-event-5) (if you haven't already). We explore different aspects of relationship compatibility using this questionnaire. * The first one hour will be spent playing icebreaker games that are meant to induce deep conversations and to explore personality traits that don't usually show up in the first stages of a date. * We will then move on to try out a multitude of board/card games that are specifically chosen to explore various aspects of relationship compatibility (moral/political values, decision making skills, personal icks etc.) * You will have a chance to interact with everyone at the event. Towards the end of the event, you will also have an opportunity to share your contact details with one other person through our matchmaker. But you're of course welcome to connect with others on your own accord. * Our attendees typically report having had a wonderful evening having explored a multitude of deep philosophical conversations and leave with the fulfillment of having had met some interesting personalities (romantic & otherwise). So if this is what you're looking for, we guarantee that you'll not leave disappointed. **[!!IMPORTANT!!]** We recommend signing up through our website to check for compatibility against other participants. This also allows you to connect with a larger audience outside the event who're in search of better relationships. We believe in conscious, compatibility based matchmaking. Don't waste your time dating the wrong people!

Donderdag 21 mei 2026 is het weer tijd voor onze Techday: hét vaste moment waarop we kennis delen, elkaar inspireren en nieuwe ideeën direct in de praktijk brengen. Deze editie pakken we het aan als een conferentie in het klein. Drie sprekers, drie verhalen, één middag – drie verhalen voor de prijs van één. Wat kun je verwachten? **Dirk neemt een kijkje onder de motorkap van AI** AI voelt voor veel mensen als magie. In deze talk probeer ik de magie weg te nemen door een kijkje te nemen onder de motorkap. Een essentieel bouwblok van moderne AI is een neuraal netwerk. Als je begrijpt hoe een neuraal netwerk werkt, is het een stuk makkelijker om te begrijpen hoe en waarom een LLM werkt. De beste manier om iets te begrijpen is door het te bouwen, vanaf scratch. Dus dat gaan we in deze talk doen. Door dat te doen leren we over artificial neurons, activation functions, backpropagation en meer. **George vertelt hoe AI Cyberaanvallen verandert** George Schizas (extern), voormalig IT Manager, nu werkzaam als CISO, vertelt over zijn ervaringen in de Cloud Cyber Security en hoe hackers met behulp van AI nieuwe aanvalsmethoden kunnen gebruiken om kwetsbaarheden op te sporen en te exploiteren. Hij geeft voorbeelden van manieren om in Kubernetes omgevingen in te breken en noemt manieren om dit tegen te gaan. **Roland duikt in de wereld van de fraude fabriek** Als ontwikkelaar kom je dagelijks in contact met technologie en de laatste jaren natuurlijk ook vaak met AI. JIJ snapt heel goed wat de voordelen en de gevaren zijn, maar hoe leg je complexe onderwerpen als AI gegenereerde afbeeldingen, Voice Phishing en Hallucinaties uit aan je ouders, de buurvrouw, of je kinderen? Ik neem jullie mee in een realistische situatie waarin Anna en haar familie opgelicht wordt met behulp van verschillende technieken en hoe dit oplichters-landschap met behulp van AI verandert. **Wanneer:** Donderdag 21 mei 2026 **Wat:** Techday – conferentie-editie “AI kansen en valkuilen” **Voor wie:** Iedereen (!) die nieuwsgierig is en wil leren **Agenda** 14:45 - 15:00 - Inloop 15:00 - 16:00 - Neurale netwerken 16:15 - 17:15 - AI risico’s en kansen 17:15 - 18:00 - Eten 18:00 - 18:45 - Fraude fabriek We zien je graag op de Techday!

(english/german below) **Bitcoin Pizza Dag!** Op 22 mei 2010 betaalde programmeur Laszlo Hanyecz 10.000 BTC voor twee pizza's — de eerste gedocumenteerde aankoop met bitcoin. Hij plaatste een bericht op een forum waarin hij BTC aanbood voor pizza; een andere gebruiker ging akkoord, bestelde de pizza's en leverde ze af. Die transactie werd later bekend als "Bitcoin Pizza Day". Laszlo bewees dat Bitcoin als ruilmiddel gebruikt kan worden. **Sluit je bij ons aan voor pizza-avond bij De Pizzabakkers! (vanaf 18:00)** RSVP zo snel mogelijk; we moeten reserveren bij De Pizzabakkers en er is beperkte plek. Zorg dat je je geladen Lightning-wallet meeneemt! *** **English: Bitcoin Pizza Day!** On May 22, 2010, programmer Laszlo Hanyecz paid 10,000 BTC for two pizzas — the first documented purchase using bitcoin. He posted on a forum offering BTC for pizza; another user accepted, ordering pizzas and delivering them. That trade later became famous as "Bitcoin Pizza Day," Laszlo proved that Bitcoin can be used as a medium of exchange. **Join us for pizza diner at De Pizzabakkers! (from 18:00)** Please RSVP as quick as possible as we need to make a reservation at De Pizzabakkers and there is only limited space. Be sure to bring your loaded lighting wallet along with you! *** **Deutsch: Bitcoin Pizza Tag!** Am 22.

Early-bird coffee and conversation at [Shibam Coffee](https://shibamcoffee.com/)!

This is a free, in person meeting. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
