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.

!!! Please note that this meetup will be held entirely in German only !!! Weil es bei den letzten Malen so schön war, treffen wir uns diesmal wieder im **CI Space auf der Bugenhagenstraße 9, 10551 Berlin** (https://maps.app.goo.gl/dXaYKm8fkhBsxk42A). Vielen Dank an Iztok Petek, den Inhaber vom CI Space (www.facebook.com/cispaceberlin), der das wieder kostenlos für uns möglich macht - bitte dankt es ihm nach Möglichkeit mit dem Kauf von 1, 2 Getränken vor Ort. **Bitte seid spätestens 5min vor 9 Uhr da, da wir pünktlich starten werden.** Die ersten sind i. d. R. bereits ab 8:30 Uhr da, um vorab schonmal ein bisschen durchzustarten mit dem Netzwerken. Denkt daran **genügend Visitenkarten,** bitte mindestens eine, mitzubringen für die moderierte Netzwerkrunde - nur wenn man euch kontaktieren kann, kann man euch im Nachgang auch empfehlen! ;) **Veranstaltungsort:** CI Space (Berlin-Moabit) Bugenhagenstraße 9 10551 Berlin Nächste **U-Bahn-Station**: U9 Turmstraße oder U9 Birkenstraße (jeweils ca. 5 Gehminuten). **Start:** pünktlich 9 Uhr (ab 08:30 Uhr sind die ersten meist schon da) Zum nun bereits 10. Mal verschlägt es uns nach Moabit! Unser Moderator [Der Gottwald (siehe hier)](www.der-gottwald.de) lädt erneut ein und führt euch durch den Morgen. Wie immer bieten wir eine moderierte Netzwerkrunde für euch an, um neue Kontakte zu knüpfen und das eigene Business voran zu treiben, außerdem ist Zeit für etliche weitere Gespräche! Ein ca. **10-minütiger Impulsvortrag** mit ganz viel Mehrwert für euch ist auch wieder eingeplant, diesmal kommt der von [Marcus Teschke](https://www.marcus-teschke.de/): Marcus unterstützt als selbständiger Berater, Trainer und Coach mit viel Erfahrung Führungskräfte, Teams und Organisationen. Er war zuvor 35 Jahre lang Fach- und Führungskraft bei Großbanken und ist ausgebildeter, zertifizierter Master Business Coach. Sein besonderer Ansatz ist die Kombination aus solider Coaching Kompetenz, kaufmännischer Expertise und sportlichen Wettkampferfahrungen als Ausdauersportler und Ultramarathonläufer. **Manche zukünftigen Slots für den Impulsvortrag sind noch frei:** falls ihr also bei einem zukünftigen Treffen selbst vortragen (oder gar mal ein Treffen moderieren) möchtet, meldet euch gern bei uns! Die leckeren Getränke, Snacks oder was auch immer euch zum Kauf animiert hat, bezahlt bitte selbst. \-\-\- **(Fast) alle** Gründer\*innen, StartUps, Freiberufler, Unternehmer und Unternehmensvertreter sind willkommen beim Business Netzwerken Meetup. Die Teilnahme ist generell kostenlos und **nicht** an eine Mitgliedschaft gebunden. **Bitte beachten:** Unternehmer mit Multi-Level Marketing-Geschäftsmodellen schließen wir von unseren Veranstaltungen komplett aus, da wir hier die Erfahrung machen mussten, dass es dabei oft nur ums Verkaufen geht, und meistens kein echtes Interesse am Netzwerken und am Gegenüber existiert. **Weiterhin** stehen wir deshalb auch allen Arten des Provisionsgeschäfts (Finanzoptimierer, Immobilienmakler, Versicherungsvertreter, etc.) extrem kritisch gegenüber und gestatten diesen keine Teilnahme an unseren Events. Solltet ihr der Meinung sein, ihr fallt nicht in diese Kategorie, obwohl ihr in einer der genannten Branchen arbeitet, so sprecht uns bitte im Vorfeld an. Wir freuen uns darauf, auch **dich** persönlich kennenzulernen und dir bei der Entwicklung deines Geschäfts weiterzuhelfen!

! All sessions in English except for 24.03, 21.04, 09.06, 28.07 & 01.09- these sessions will be in German ! Wanting to connect deeper with your partner? Looking for new ways to be intimate? Hoping to foster love, awareness, and communication in your relationship? Take some quality time away from the daily grid and explore Tantra together through embodied practice. The practice is designed to foster deeper intimacy, attunement and harmony between the two of you. Tantra invites you to allow your life force energy to flow without inhibition and to cultivate it for self-realization. Part of the practice is about inviting in more opening. Openness creates union, resistance creates separation. Deep connection, more pleasure and joy are a result of experiencing more openness. Tantra is for everyone! All couples are welcome regardless of sexual orientation and experience level. Not in a romantic relationship? Feel free to bring anyone you'd like to practice Tantra with. **What to expect:** * **Discourse, demo practice and Q&A**: learn about Tantra through discourse, ask your questions * **Tantra meditation practice**: presence, movement, sound and breath * **Sharing before and after practice**: share about your fears and desires & reflect on your experience * **Cozy studio setting**: enjoy a comfortable and intimate environment * **No partner-exchange:** practice only with your partner * **Fully clothed:** you may keep your clothes on during the entire practice **What to bring:** * Wear comfortable clothing * Water bottle to stay hydrated **Tickets:** 69€ per couple. Please purchase your ticket via [sophieheldens.com](https://www.sophieheldens.com/tickets?utm_source=meetup&utm_campaign=datenight) **Location:** Praxis Köpi Köpenicker Straße 175 10997 Berlin Kreuzberg Walk to the second courtyard and take the stairs to the front door on the left. **Please note:** Praxis Köpi is located on the 5th floor and there is no elevator available. Only book a ticket if you can walk the stairs. The benefit: a beautiful private studio with loads of natural light. **!! Please arrive 10 minutes early so we can start on time !!** Once we start the session, I can’t let you in anymore because it disturbs the class. Please do yourself and the group a favour by coming on time. Thank you! **Workshop facilitator** Hi! My name is Sophie. My passion for Tantra is rooted in a deep spiritual yearning and an inner knowing that Tantra is my path. My desire to teach Tantra has been sparked by having witnessed my own growth and healing as a result of these practices and it is inspired by a vision to create a more beautiful world. I create a space that is loving and nurturing, with a strong emphasis on ensuring that you feel save and supported. My workshops are gentle yet transformative, spiritual yet grounded and always heart-centered. I'm passionate about bridging the wisdom of ancient Tantra with modern-day practices.

Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00 - Doors open** **18:30 - Keep Off My LAN: Firefox's Implementation of Local Network Access** In June 2025, researchers exposed Local Mess — a tracking vulnerability where Meta Pixel and Yandex Metrica scripts abused localhost access to silently track millions of Android users across the web. The web platform had a long-standing hole, and Firefox moved quickly to help close it. This talk presents Local Network Access (LNA), the emerging standard that finally tackles these threats along with a backlog of security vulnerabilities tied to localhost and local network devices. It walks through the specification, Firefox's implementation, and the real-world deployment challenges encountered along the way and how they were mitigated. Beyond the "what," this talk opens up a conversation. As LNA is still taking shape in the WICG, it's a chance for people building in the local network and localhost space — and for the adblocker and anti-tracking community, especially those running DNS-based blockers (Pi-hole, AdGuard Home, and similar) — to surface edge cases, breakage, and threat models that should be designed for. Anyone running services on localhost / local network, or operating local DNS-based tracking protection, is invited to share what LNA needs to get right. About the speaker: Sunil Mayya is a software engineer on Mozilla's Firefox Networking team, based in Nuremberg, and a core contributor to Firefox's implementation of the Local Network Access standard. **19:30 - The Devil is in the Defaults - what to do about XSS** This session is about latest defenses against Cross-Site Scritping (XSS), the most prevalent security issue of all times. We will showcase typical XSS bugs and how they can be avoided. We will also explain why previous mechanisms fall short of protecting web sites at scale and why we believe Trusted Types and the Sanitizer API can help closing this gap. The presentation will also give hands-on advice to enable security and development teams adopting these new protections. We will close with a bit on security considerations and remaining risks. About the speaker: Frederik Braun is a security engineer and manager working on Firefox.
