With warm & good weather on the horizon again, it's time again to get more picnic-y & outdoors-y 🌄 For this new season, let's revisit the old picnic gathering formula, but add into the night vibe & spicy dance theme (in this case tango, because other dances are oversaturated with events 😊) The premise: A picnic gathering starting from 19:00 & ending 23:00 sharp Since it's evening vibes, BYO food/drinks/games still applies but think time appropriate (don't go big on alcohol though!) Dancing aspect, music starts 20:00 & ends 23:00 sharp! Exact location in Griftpark: To be concluded, but assume close to where the meetup event location currently is set at Additional notes for the tango aspect: * you're very much welcome to join in & dance, even with no experience. I can show you a thing or two so you can get a taste & give it a go 😊 Depending on how many, either via a quick group tryout or I help you out individually * The tango aspect of the event is through the Utrecht Tango Cafe Milonga community (also organized by Constantinos) More info --> https://www.utrechtcafemilonga.com If you have any further questions, feel free to message the host Depending on the time & weather, and whether people are up for it, follow-up drinks can always follow later that day. To those interested, I hope to see you there! 😄

**Date & time** Friday, July 3 - 18:00 – 21:30 **Location** Wonders of Work: in winkelcentrum Hoog Catharijne, Utrecht. Check the [route](https://wondersofwork.nl/nl/route/)! **Registration:** Event is free, but registration is required. [Please fill out the form.](https://docs.google.com/forms/d/e/1FAIpQLSd_8NtZo-WOm_eX_2T9zDYOpON290TzNnufh2P8Lz70LF4S7Q/viewform?usp=publish-editor) Event description Do you know the boundaries of the planet we call home? Today, seven of the nine planetary boundaries have been crossed, putting increasing pressure on Earth’s life-support systems. To secure a safe and just future for all, we must understand how human activities interact with the Earth system - and act decisively to reduce pressures on our planet and its ecosystems. The Planetary Boundaries Fresco is a half-day collaborative, science-based game experience that brings the planetary boundaries framework to life through guided discussions and an interactive card game. Together, you'll explore the processes that regulate Earth’s stability, uncover how human pressures drive changes across the planet, and identify leverage points for action. The game is created and will be facilitated by Elise and Joy from [Somewhat Greener.](https://www.somewhatgreener.com/studio/) **More information about the workshop:** [https://www.somewhatgreener.com/workshops-and-events/planetary-boundaries-fresco/](https://www.somewhatgreener.com/workshops-and-events/planetary-boundaries-fresco/)

'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.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
