At 10.30AM on Saturday 4th of April we'll start at our meeting point Houten Castellum train station, where we'll be waiting you in the tunnel under the train station. On our way we'll pass several sights, including the colorful houses at the Rietplas (yes, there will be time to make some photos there), the Amsterdam-Rijnkanaal and Kasteel Schonauwen. Do you think about joining, but you're not sure what this is about? Well, Utrecht Hiking Community aims to organise one hike per month. If you're in for a hike with a bunch of friendly other people, you are very welcome to join, no matter whether you are an expat, professional, nomad, local or a student. The hikes are a way to meet people while being active and exploring a place you might not be going to otherwise. If your aim is to hike fast, we might not be the right hiking group for you though. For us it's more about having a fun walk, seeing nice places and socialising. Don't forget to put it into your agenda: Saturday 4th of April, 10.30AM - hiking time! 😀 Bring good walking shoes, your phone/photo camera, something to eat/drink for on the way and a good mood! Please find us on Instagram for all the latest updates and impressions of previous hikes: [https://www.instagram.com/utrecht.hiking.community](https://www.instagram.com/utrecht.hiking.community) We have some costs for organising these hike, like travel costs and the yearly MeetUp subscription. Therefore we'd be very happy for any donations to support us by using this link: [https://www.ing.nl/payreq/m/?trxid=ezoLJAAlYUgQRGhEpGTcMpI1mb9Rlk29](https://www.ing.nl/payreq/m/?trxid=ezoLJAAlYUgQRGhEpGTcMpI1mb9Rlk29) Are unforeseen circumstances causing you to arrive late to Houten Castellum train station? Then please write to +31621177691. We won't let the whole group wait for you, but we can send you our live location so you can come after us. There are no public toilets at Houten Castellum train station or on the way. Therefore please visit a restroom before arriving. Dogs are allowed on this route. After the hike there is an option to go for lunch/drinks in the Castellum shopping center. See you on Saturday 4th of April!

This hike picks up the trail where we left it on March 8, in Culemborg. We then crossed the river Lek. We will now continue southwards to the river Linge, over mostly unpaved (and sometimes muddy) paths. With some luck, we will see apple, pear and cherry trees in full bloom, as they grow abundantly in this area. **Meeting time and place**: we will meet at **10.15am** at train station Culemborg. The hike ends at train station Beesd, where we will arrive around 3pm. **This hike is fully booked.** [You may sign up for a place on the waitlist on my website](https://rewildyourself.nu/dutch-nature-hikes/)**.**

🌸 **Free online gathering** **Next circle: April 5** After this, we will continue meeting on the **first Sunday of each month**. A space to begin the month by returning to yourself. This women’s circle is an invitation to give yourself one hour to pause, slow down, and reconnect with your body, your inner voice, and other women. A simple and caring commitment: beginning the month with meditation and journaling in community. You can think of it as a small personal ritual, creating the habit of listening to yourself, writing, and setting intentions for the month ahead. We meet online on Sunday afternoons to gently transition into a new week and a new month, creating a moment of presence, reflection, and intention. During this 1-hour session we will explore: ✨ a guided meditation to arrive in the body ✨ a journaling practice to connect with what is alive in you ✨ a space for sharing, where you are welcome to speak or simply listen No previous experience is needed. You are welcome just as you are. Please have a notebook and a pen nearby, and join from a quiet space where you won’t be interrupted during the session. You are welcome to join once, or come back each month. The choice is yours. The first circles are offered for free in order to create community and open this space to more women. Participants who register for the event will receive the **Google Meet link** before the circle begins. It will be lovely to welcome you into this space 🌿

Hi everyone! For those who want to enjoy a particularly unique adventure in (mostly) nature, you're welcome to join me in this special Easter hiking excursion! Pay attention, the route is 40km so it's not absolutely hike beginners. For first-timers (and as a helpful reminder 😉), I recommend that you wear a comfy outfit & shoes and bring (lots of) water & a snack or two. At some points during the excursion, we will do breaks to rest and eat/drink for a while. But expect a steady pace faster than the normal hikes but not powerhiking pace. I'd saythink on average 5km/h. It's a marathon not a race 😜 Lastly, after the hike we 100% go for food and drinks. More info about the route/location: It's simple. Put on Google maps starting point Utrecht centraal & end point Amsterdam centraal, and there's your route 😊 More tips on finding the group along with helpful contact info with the host will follow in the comments the day before the meetup. To those interested, hope to see you there! 😄 In case of bad (NL) weather, the event might be moved to another day or canceled

*Since the event will be in Dutch, this description is too.* Ben je benieuwd naar wat het Tibetaans boeddhisme inhoudt en zoek je een plek waar je op een ontspannen en toegankelijke manier kunt kennismaken? Of ben je gewoon op zoek naar een moment van rust, meditatie en reflectie? Dan ben je van harte welkom bij *Heart of Compassion*, een reeks zondagochtendbijeenkomsten waarin compassie het centrale thema vormt. Aan deze activiteit kun je per keer meedoen. Tijdens deze ochtenden beginnen we met een gezamenlijke meditatie. Daarna volgt een korte inleiding op een boeddhistisch thema, zoals de [Vier Edele Waarheden](https://nl.wikipedia.org/wiki/Vier_edele_waarheden), compassie voor jezelf en voor anderen. We nemen vervolgens de tijd om samen stil te staan bij het onderwerp, in de vorm van een gesprek of een geleide meditatie die uitnodigt tot reflectie. **Voor wie?** Of je nu net begint met het verkennen van boeddhisme of gewoon op zoek bent naar een moment van rust, iedereen is welkom. Ervaar de kracht van compassie in een toegankelijke en rustige sfeer. **Praktische informatie** -Begeleiding: Eline Rinchen Dorjee-Weiman -Ontvangst: vanaf 10:15 uur en na de bijeenkomst is er tijd voor een kopje thee -Plaats: [Jewel Heart, Hatertseveldweg 284, 6532 XX Nijmegen](https://maps.app.goo.gl/D4FzqLbkaqs2JNDG8). Loop de oprit op en dan zit de ingang aan je rechterzijde -Kosten: Aan deze bijeenkomsten zijn geen kosten verbonden -Aanmelding is niet nodig Kijk ook naar onze andere [open activiteiten](https://www.jewelheart.nl/nl/open-activiteiten/) en [cursussen](https://www.jewelheart.nl/nl/cursussen-overzicht/)

**We have limited space at the café, so if you've RSVPd and can't make it, please cancel as early as possible so another person can join!** Join in for a morning of crafting & chatting over a drink. Just bring your own project and payment for drinks. Meet fellow crafting enthusiasts, whether it's knitting, crocheting, stitching, origami, or something more unique! We talk about our projects, exchange tipps, but also just get to know each other and enjoy a relaxed Sunday morning in good company. We now also have a WhatsApp group, where we want to organise get-togethers and other events. Ask one of the organisers at the next Meetup you join for more information and access.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
