Classes every Monday, Wednesday and Friday from 19:00 to 21:00. **!!SIGN UP HERE**: [Katori Shinto-ryū Berlin Sign-up (google.com)](https://docs.google.com/forms/d/e/1FAIpQLSeBt4A13VgnEcgQQ2PDaruthmYMRWineG4KtUCKsuC9KBsCUQ/viewform) Registration is required before your participation so that we can prepare enough training equipment. **Address**: Belziger Str. 25, 10823 Berlin. **No previous experience required!** The classes are in English and German. **Our website**: [Kenjutsu Berlin - Official school of Katori Shinto-ryu in Berlin (katoriberlin.org)](https://katoriberlin.org/) **Katori Shintō-ryū** is one of the oldest Japanese sword fighting traditions (koryū) still practised today and is recognized by the Japanese government as a cultural intangeable asset. The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.

This is a **casual, in-person Mavericks meetup** centered around movement rather than conversation alone. We’ll meet at a bouldering gym, climb at our own pace, take breaks, and let conversations happen naturally in between. There’s no training, no coaching, and no performance expectation. Bouldering is chosen deliberately: it’s simple, physical, and clears mental noise fast. You’re focused on the wall, your body, and the next move—which makes everything else drop into the background. This meetup is about: * moving your body * getting out of your head * spending time with people who don’t need constant explanation * letting connection happen without forcing depth You don’t need to be an experienced climber. If you’re comfortable trying things, resting when needed, and staying curious, you’ll be fine. 📍 **Where:** Ostbloc Hauptstraße 13, 10317 Berlin 🕒 **Duration:** Approx. 2 hours (come and go as it fits) 👥 **Group size:** Limited spots to keep it relaxed and manageable Bring comfortable clothes, climbing shoes if you have them (rentals are available), and a normal human level of social energy. No agenda. No outcome. Just movement, presence, and seeing how it unfolds.

We play half court 4x4 amateur basketball. All levels are welcome but you should be able to play and know the basic rules. Don't be alarmed by the low attendee number, this group is mostly managed through WhatsApp today, we'll add you when you come play.

A Berlin meetup bridging Product, UX, Design, and Dev to build better products, faster. A collaboration between UXDX Community and UX Gym. This is our first event of the year, and it's in person. Throughout 2025, we'll host more events and partner with conferences to bring you exclusive discounts. **[Registration Link](https://uxdx.com/community/community-berlin-2026-02-10/)** **From Marketplaces to Neighborhoods** An exploration of how eBay uses design to shift its experience from a global marketplace to a more local, human, and connected ecosystem. [Yihui Liu](https://www.linkedin.com/in/yihui-liu-b98627121/)[,](https://uxdx.com/profile/yihui-liu/)Senior Product Design,eBay **3 Months to 2 Weeks: Using AI to Build MVPs in a Single Design Sprint** Design tools come and go. The craft stays. Over the past year at Bonanza I've been testing where AI actually fits into how we work. Not as a replacement for thinking, but as a way to show up to a design sprint with something tangible. We now walk into day one with a working prototype. Clients see real interactions, not wireframes. Conversations shift from "imagine this" to "try this." That compression changes everything downstream. On February 10th, I'm breaking down our process at the UXDX Community event in Berlin. How we use Claude Code and Figma Make to go from brief to functional MVP in two weeks. What worked, what flopped, where the hype doesn't hold up. If you're a product leader or designer trying to figure out where these tools actually fit, this one's practical.

*Please note, this event is free but please sign up here so we can inform the venue of your attendance: [https://uxdx.com/community/community-berlin-2026-02-10/](https://uxdx.com/community/community-berlin-2026-02-10/)* Design is changing — both in what we build and how we build it. This month we’ll explore how teams are designing more local, trust-driven experiences that connect online and offline behavior, and how AI is reshaping the way designers move from idea to working prototype. Together, these perspectives show how design is evolving at both the strategic and execution levels: from what we build for people, to how quickly and effectively we can build it. **AGENDA:** **6:00 PM:** Registration and networking **6:20 PM:** Welcome from UXDX Berlin **6:30 PM:** Talk: *"From Marketplaces to Neighborhoods"* with **[Yihui Liu](https://www.linkedin.com/in/yihui-liu-b98627121/),** Product Design Lead, eBay An exploration on how eBay uses design to shift their experience from a global marketplace to a more local, human, and connected ecosystem. **7:00 PM:** Talk: *"3 Months to 2 Weeks: Using AI to Build MVPs in a Single Design Sprint"* by **[Behrad Mirafshar](https://www.linkedin.com/in/behradmirafshar/),** CEO, Bonanza Studios Practical walkthrough of how they've compressed the design-to-working-prototype cycle using tools like Claude Code + Figma Make.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Love and Monsters,”** on the inescapable bond between romance and horror, with Joshua Barton, scholar of horror and lecturer in English at Virginia Commonwealth University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/nv-love-monsters](https://www.ticketleap.events/tickets/profsandpints/nv-love-monsters) .] Romance and horror might seem like opposite genres, but they share a deep emotional core, and the combination of them has captivated audiences across time and culture. Put even your worst Valentine’s Day in perspective by hearing this strange relationship discussed by Joshua Barton, who has earned a big following among Profs and Pints fans with his past talks on cryptids, American horror, and Christmas ghosts. He’ll explore the undeniable and unsettling intersection of romance and horror and examine how and why love and fear intensify each other and combined to create tension, drive narratives, and explore human vulnerability. We’ll look at works that have blended passion and terror, including Gothic literature like the vampire novella *Carmilla* and modern films like *Spring* and *Crimson Peak*. We’ll study the fine line between obsession and adoration running through Stephen King’s “I Know What You Need,” Adrian Lyne’s *Fatal Attraction*, and the timeless *The Phantom of the Opera.* We’ll discuss the seeds of monstrous love that were planted with *Beauty and the Beast* and *Creature from the Black Lagoon* and bloom ferociously in works like *Twilight* and *The Shape of Water*. Through it all, we’ll find the threads of otherness and the taboo that intertwine horror, love, and reflections on identity. Join us for a journey through storytelling that combines the grotesque and the scintillating as we uncover why romance and horror are a match made in the dark. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: From the original 1954 advertising poster for *Creature from the Black Lagoon* (Artist: Reynold Brown / Public Domain).

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.

Join our weekly walking meetup to have fun, maintain a healthy lifestyle, meet new people, and enjoy the weather! We meet Saturdays at 10am, halfway between the Reston *Container Store* and *Not Your Average Joes* (by the metal benches), leaving no later than 10:05. Every week, rain or shine, we start by walking along the Green Trail to reach Lake Anne Community Center. Once there, we pause for water/bio (often staying a few minutes extra from April-November, due to the local Farmer's Market), and then we circle Lake Anne and head back to our starting point. It's roughly 3-4 miles and takes about an hour and a half. Afterwards, some members will often head to *Not Your Average Joes* or another local restaurant for a quick drink/meal before tackling the day. This event is open to all ages and fitness levels. Dogs are welcome, and we recommend dressing for the weather (umbrella, water, snow shoes, hat, etc.) since we'll walk rain or shine. Also, feel free to bring a friend! By signing up, you accept and assume all risks and responsibilities with this activity, and nobody will be held liable.

Voices of Mount Pleasant Toastmasters is a new faith-based club sponsored by Mount Pleasant Baptist Church of Herndon which is open and all guests are welcome to attend. It is a pleasant fusion of Public Speaking and Leadership training with fun and fellowship. Opening with an invocation, the Club president provides guests the opportunity to introduce themselves to the group with a short elevator-speech and introduces the Toastmaster to lead the meeting with a theme. The General Evaluator and team are introduced to let attendees know the word of the day, the timing of speeches and evaluations, and the filler-words, which wil be counted. In the first segment of the meeting, there will be 1 or 2 prepared speeches from projects studied in the Toastmasters education program (Pathways). In the second segment of the meeting, willing attendees are selected to receive information or a question from the Table Topics Master to give a 1-2 minute impromptu speech. In the third segment of the meeting, the General Evaluator introduces the Evaluator for each prepared speech; reintroduces the Timer, the Ah-Counter, and the Grammarian for reports. Next, the General Evaluator gives a summarized review of the structure and leaders of the meeting. An Educational Moment will be given to explain the Toastmasters Educational Program (Pathways) as an introduction to new members and guests. The presiding officer will make announcements, ask visitors to the club for their impression of the meeting for feedback, ask for prayer concerns, and give a benediction to end the meeting. The group is mainly made up of members of the church who joined Toastmasters for the first time with the chartering of the club in September of 2023. So everyone is learning together and encouraging one another.
