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.**

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

Sunday will hopefully be a sunny day. We’ll meet at S-Bahn station Grünau, on the sidewalk level inside the station (exit Adlergestell/Wassersportallee). We will hike this tour: https://www.komoot.com/de-de/discover/S%E2%80%91Bahnhof_Berlin-Gr%C3%BCnau/@52.4128380,13.5736270/tours?sport=hike&map=true&toursThroughHighlight=388182&focusedTour=1268215602&pageNumber=1 , but make a shortcut in the middle of the tour. Please prepare for a rather speedy hike. (Bring comfortable shoes, for instance.) There are no cafés or restaurants along the way, so bring your own food and drinks. If you need to contact other participants during the hike (for example, to find out where to meet us if you are running late), please use the Signal group link that I will send to all participants via private message three hours before the hike. This timing is intended to prevent non-participants from misusing the link for unwanted advertising, which has happened in the past. Signal also allows us to share our locations during the hike without involuntarily forwarding this information to the intelligence services of authoritarian or non-authoritarian states. For all other purposes, especially socialising and posting photos, please use the Telegram subgroup 'Event Chat & Photos': https://t.me/addlist/KAOk2PA4BDE0ZTY8 . The hike will take place if at least 6 people sign up. As long as there are more than 6 people, you can sign up and cancel as many times as you like. If there are 6 or less people, please avoid cancelling, as this might make the other participants feel insecure about whether the hike will take place (or whether there is something wrong with the hike and they should cancel as well --> [Matthew effect - Wikipedia](https://en.wikipedia.org/wiki/Matthew_effect)). If there are less than 6 participants, the hike will also take place unless the majority of the participants are in favor of canceling the hike.

Nach dem Spazierengehen können wir noch ins Café, um die vorangehenden Gespräche zu vertiefen und zu connecten. Kleiner Hinweis: \- Unsere Walk & Talk Events finden auf Deutsch statt\. \- Wenn du doch nicht dabei sein kannst\, dann melde dich bitte vom Event ab\. So können wir das Event besser planen\. Freuen uns auf eine nette Truppe.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
