Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

Sundays, 13:00-15:30, May 10-June 28 Class Show: Sunday July 5 Prerequisites: none! ImprovWorks Berlin is excited to announce our next round of improv comedy courses! We truly believe that everyone can become confident and funny on stage. Over 8 weekly classes, we explore the principles of comedic improvisation primarily through short-form games. Together, we create a conscious, supportive space where we focus on becoming good listeners, making spontaneous choices, and working together as a team. We’ll empower each other with the “Freedom to Fail,” thereby unleashing our inner creativity. The concepts of presence, agreement, trust, commitment and support are fostered through large and small group exercises. We’ll also have a ton of fun and make new friends! In the end-of-class show, you’ll get to show off all you’ve learned to an invited audience of family and friends. Sundays, 13:00-15:30, May 10-June 28 Class Show: Sunday July 5 Spots are limited in these small classes, so sign up soon!

Let's meet for the [ACX Spring Meetups Everywhere 2026](https://www.astralcodexten.com/p/meetups-everywhere-spring-2026-times) in the Humboldthain! This will likely be a big meetup, as it was announced by Scott on ACX. From experience, I expect 25–50 attendees. Humboldthain is good to reach by public transport; the next train stops are S+U Gesundbrunnen and S Humboldthain. If you’re reading this, you’re invited. Please don’t feel like you "won't be welcome" just because you’re new to the blog, demographically different from the average reader, or hate ACX and everything it stands for. You'll be fine! I'll buy some snacks; feel free to bring something to share as well. There are also many restaurants around if you get hungry. Location: Big lawn at the center of Humboldthain — [https://plus.codes/9F4MG9WP+36](https://plus.codes/9F4MG9WP+36) Contact: Reply to this event, message me here on Meetup, or join the Telegram group below.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
