[*Registration form required below*] **Interested in Japanese sword fighting or Japanese culture? Come join a trial and experience the traditional Samurai art at Katori Shintō-ryū in Schöneberg.** **Trial Fee**: **25€**/ session (2hr). 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.

Register: [https://globalai.community/e/7lns53g4](https://globalai.community/e/7lns53g4) ## Connected Intelligence: AI Builders Meetup — WeAreDevelopers PreDay, Berlin AI agents are moving into production. The question is no longer whether to use them, but what it actually takes to make them work once the demo is over. This WeAreDevelopers PreDay meetup is for builders, founders, and practitioners wiring AI agents into real codebases, CI/CD pipelines, developer platforms, and knowledge systems. The evening focuses on the honest conversations that rarely fit into a conference talk: what breaks at scale, what context engineering really looks like, and where the failure modes hide. The theme is **connected intelligence**: how graph-based reasoning, smarter pipelines, and agentic code review are changing production AI systems, and what engineering teams need to do differently to support them. We will explore constraint satisfaction in agent decision-making, agentic AI in production, AI-powered development workflows, and Java’s role in the future of AI systems. No vendor pitches. Just the stuff that runs in production.

Hi everyone, join us on Sunday, July 12, at Monbijou Park for a fun afternoon all about MBTI and other interesting topics. Whether you’re deep into cognitive function theory or you just heard about MBTI this week, we’re happy to have you here. Looking forward to seeing you there! Our group aims to bring together people who are interested in self-development and self-improvement using MBTI and cognitive functions, in order to learn more about the theory and share our experiences with it. Another reason for this meetup is to meet people with whom you might potentially get along really well based on your type. This can lead to meaningful connections :)
Although the meetup is geared towards people who are interested in learning about MBTI theory and using it to improve their lives, our conversations aren’t only about that! We talk about anything and everything. So it's more like a regular social meetup with the aim of avoiding small talk :)

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.

This presentation will be by Ben Iten, humanist chaplain and HCCO Board Member. Speaking on expressing Humanism values in American democracy. This meetings will be hybrid. You can meet us in-person or attend online. The formal presentation will start at noon. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.

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.
