Ready for a scenic hike? We’re heading out for a beautiful 19 km hike around Lunteren, passing forests, sand drifts, and even the official geographical center of the Netherlands. Expect beautiful nature, good conversations, and a great way to meet new people! 19 km is also a perfect first training day for the [PLN charity walk](https://www.meetup.com/nijmegen-explore-and-more/events/313573496/). And you’re of course also absolutely welcome to come if you’re not joining the fundraiser. Come for the nature, the social vibe, or just because you enjoy a solid hike. **What to expect** 📍Distance: \~19 km 🌲Terrain: mostly forest paths, sandy sections and heathland (varied and scenic) 🚶**‍**Pace: relaxed but steady ☕Breaks: there are some nice spots for a couple of breaks **Times & places** ⏱️**12:15** Start at [Lunteren train station (Spoorstraat 4, 6741 DE Lunteren) ](https://maps.app.goo.gl/6uPDXGh8ATBDJJQe9) 🏁**17:00** Back at starting point (estimate depending on pace and breaks, flexibility helps) **Cost** 💰[A €7.50 donation](https://www.detikkendeklokchallenge.nl/fundraisers/sam/donate) (or more 😉) to the PLN fundraising walk.

Just send me a message! 🎗️This event is free if you have already signed up for our team in the [PLN fundraising walk](https://www.meetup.com/nijmegen-explore-and-more/events/313573496/) ❤️‍🩹The brother and mother of one of my best friends have been diagnosed with PLN, a genetic heart condition. This disease still has no cure and crucial research is at risk of slowing down as international funding becomes uncertain due to the changed political climate. That's why we are trying to raise funds, so this very important research can continue. **Preparation** 🥾This is a friendly training distance, suitable if you’re comfortable walking longer routes. No speed needed, just a positive mindset. 🥪Bring water, snacks, weather-appropriate clothing, and comfortable shoes. ❓Questions? Send me a message, happy to help :-) **Event Policies** ⚠️ Disclaimer: Participants are responsible for their own safety. Please stay with the group and respect nature at all times. ⚠️ Cancellation: The event will be canceled in case of severe weather conditions (you’ll be notified in advance). A refund is not possible because this is a fundraiser, the money goes directly to a good cause. But I will try to reschedule a worthy replacement event :-) ⚠️ No-show might result in ban: Marking yourself as "going" takes a spot away from others for limited capacity events like this. If you are marked as going but don't show up, you might be banned from the *Nijmegen Explore & More* group

Join us on a 7km hike from Amersfoort Vathorst train station to Landgoed Hoevelaken and back. From Vathorst Station we'll walk through a residential area for around 15 minutes until we'll cross under the A28 highway and head into Landgoed Hoevelaken. Here we'll walk on a mixture of long forest lanes and smaller winding forest paths. After crossing the provincial road to Nijkerk we'll also walk through the Overbos forest. At the end we'll head back to Vathorst train station via Nijkerkerveen village, some meadows and along the railways. Utrecht Hiking Community is organising one hike per month. Our aim is not to hike fast, but to hike "gezellig". It's intended to be a mixture of being active in nature, exploring places in and around Utrecht and meeting fellow hiking enthusiasts. Everybody is welcome to join, no matter whether you are a beginner or a hiking pro, expat or a local, student or professional (or maybe even retired). Also you can come with friends, but alone as well. At our previous hikes there were always many people who didn't know any of the other hikers, so it's a perfect opportunity to get to know some fellow hiking enthusiasts. If you like this idea and want not only to participate but to support us as well, you can help us by making a small donation using this link: https://www.ing.nl/payreq/m/?trxid=L9Z0gDbAfY48ETP1VhKdTHId88RaaaDe We're using these to cover for our travel costs and MeetUp subscription (about €200 a year for event organisers). We'll start our hike at 10.30AM and will meet in the tunnel under Amersfoort Vathorst train station. Please try your best to arrive on time, since if you arrive later, we won't make the whole group wait for you. You can however send a message on WhatsApp to +31621177691, so we can send you our live location and you can try to catch up with the group. For those coming by car, there are a few parking places at the end of the Amendijk street in Hooglanderveen, which are directly next to the train station. At the nearby Vathorst shopping center there are many more free parking places. After the hike, after arriving back to Vathorst train station, we can go for a lunch with anybody who wants to in the nearby Vathorst shopping centre. What should you bring for this hike? Good hiking shoes (about half of the route is paved and the other half is unpaved), a bottle with water or anything else you'd like to drink on the way and of course a good mood are the only things really necessary. Also don't forget to put on some SPF. A few other practical things that are good to know: Dogs are allowed on this route, but need to be kept on a leash while we are not walking in Landgoed Hoevelaken. There is no toilet at Amersfoort Vathorst train station, so please make sure to visit a toilet before you depart to Amersfoort Vathorst. Alternatively you can go to the toilet in the library in the Vathorst shopping centre, but it's a 3 minute walk from the train station to get there. We will make some photos during the hike for on our social media (Instagram: @utrecht.hiking.community). If you don't want to be on any photos, you can still join, but please notify the organisers before the hike. And finally, in case of very bad weather we might postpone the hike to another date. Right now it doesn't look like we may expect that kind of bad weather, but just for in any case, please check this event for any updates on the evening before the hike. See you on Saturday!

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.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

You can sleep in on the Semiquincentennial (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. Thanks to the team at Nationwide of supporting the group.
