In this Yin practice, we take time to pause, soften, and simply be. With the support of long-held, floor-based postures, the body gradually opens, accessing the deeper layers of fascia and energy pathways. We allow gravity to guide the process. This subtle work calms the nervous system, nurtures stillness, and encourages quiet reflection. It's an opportunity to release tension from both body and mind, and to reconnect with yourself on a deeper level. The class is led in English and is open to all levels. .

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)**[ Signal group](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. This time, our main topic is going to be dependency-tree security. Jan-Erik will share insights into how security is upheld at Mozilla — in the Firefox project — in the context of third party open source library packages and repeated attempts at attacks through malicious crates. If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 22 January 2026 is our tenth meeting. Our next projected meetings are going to occur on the following dates: * 19 Feb 2026 * 19 Mar 2026 * 16 Apr 2026 * 14 May 2026 * 11 Jun 2026 * 9 Jul 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the Berlin Rust Hack and Learn online meetup's [Matrix channel](https://matrix.to/#/!xycQxSjSAvEezkyztA:chat.berline.rs). You are very welcome to join!

If you’ve ever wondered how to paint with watercolours but didn’t quite dare to start, this class is for you. **Begin the year with a relaxed and creative introduction to watercolour, specifically designed for beginners and curious creatives.** In this workshop, we’ll explore the essentials of watercolour painting: how water and pigment interact, how transparency works, and how to control (and enjoy) the unexpected effects that water can create. **We’ll practice wet-on-wet techniques, layering washes, creating soft textures, and playful effects using salt, splashes, and lifting colour**. Most importantly, we’ll focus on letting go, experimenting, and building confidence with the medium. No previous experience needed—just curiosity and a willingness to explore. This class is about learning the basics while enjoying the process and discovering your own creative flow. ### **Fridays 16 - 23 January** from 6:00 to 7:30 PM **In Friedrichshain**, Berlin (exact address by e-mail) Join us for one or both classes, as you prefer. They are independent but complementary. **Price:** * 27€ x class / 50€ x 2 classes Payment via PayPal / Bank transfer **Material:** Material for watercolours is very specific. If you use poor-quality or non-professional material, you won't achieve the optimal results. Please check this helpful guide: [https://www.instagram.com/p/CKWdOx6FczD/](https://www.instagram.com/p/CKWdOx6FczD/) I recommend bringing your own material so you can keep practising at home after the classes. If you don't want to buy it, I can also lend it to you for a small extra fee. Get in touch. ### **Booking only by E-mail:** Email: **hola.berlinartclub@gmail.com** You’ll receive payment details and the exact address upon confirmation. 🎟️ **Spaces are limited—join us!** RSVP here does not save you a spot. www.lujancordaro.com [@lujancordaro](www.instagram.com/lujancordaro) [@berlin.art.club](www.instagram.com/berlin.art.club)

**Silent Reading Book Club** A new way to enjoy reading! Ditch the old book club, where everyone has to read the same book…this is better! It works like this: Bring your own book. Come chat, have some tea or coffee, get to know your neighbors. Then we quietly read together, side by side, for about one hour, each one reading their own book, and afterwards we talk with each other about what we are reading. You may read in any language, you may read any book. We are a group of international residents of Berlin from many different countries, of all ages, and we converse in English. We welcome you! no registration needed- the event is donation based

This pilgrimage hike invites us to step out of everyday noise and practice attentive walking. Moving along water, forest paths, and forgotten places, we create space for silence, listening, and noticing what is usually overlooked. 📅 **Date & Time** * **Date:** Saturday, January 24, 2026 * **Start:** 9:43 AM at Oranienburg Train Station *(Travel via RE6 from Berlin Gesundbrunnen at 9:23 AM; arrival also possible via RE5 or S1)* * **Duration:** Approx. 5–6 hours * **End:** Lehnitz Train Station *(S1 back to Berlin every 20 minutes; return from Oranienburg also possible)* 🗺️ **Route Highlights** * [Komoot tour](https://www.komoot.com/tour/2734537596) * Walking along the shore of Lake Lehnitzsee * Paths beside the Oder–Havel Canal * Forest sections near Schmachtenhagen * Stories and background about the history of the places we pass 🤔 **Why This Hike?** Listening and silence are essential when we want to orient ourselves for a new year. This pilgrimage invites reflection on questions such as: * What do I actually perceive when things become quiet? * What usually gets lost beneath daily distractions? * Can I allow silence without immediately filling it? There is no pressure to perform, achieve, or “optimize” anything. We simply walk – attentive, open, and together. This pilgrimage is an opportunity to slow down, reconnect with nature, and reflect on life’s important questions. We’ll walk at a relaxed pace, share thoughts, and take time for moments of silence – about 30 minutes to an hour– to listen to nature and our inner voices. 🔔 **What to know & bring** * It’s winter, dress for the season and the weather. Important: hiking or running shoes, warm layered clothing, hat and gloves. * Bring enough food and water for the whole day, as we won’t stop anywhere to buy snacks or drinks. A thermos with hot tea or coffee is highly recommended! * Don’t forget your public transport ticket for the way there and back. * There may be an option for a quick winter dip. If you’d like to try it, bring swimwear, a towel and extra clothes to warm up afterwards. 📩 **Questions & Registration** If you have questions or need help with planning your trip, feel free to reach out. You’re also welcome to join our WhatsApp group for updates and connection before the hike. Feel free to contact Pilgrim Guide Alexander via WhatsApp message (+4915757652601) or email (alexander.steinfeldt@outlook.com). **Waitlist = You're in! 😊** Currently, only 10 members can officially register on Meetup (due to the restrictions of the free version). However, you’re welcome to join the hike by joining the Whatsapp group for this event (Message me directly to confirm your participation and get the link for the Whatsapp group).
