**Research Harness Engineering**
[Florian Hönicke](https://www.linkedin.com/in/florian-h%C3%B6nicke-b902b6aa/) — Elastic
Every programmer is now a manager of coding agents — but human oversight quickly becomes the bottleneck. Florian will share how Elasticsearch built an agentic research harness to support their v5-omni model development, enabling structured experimentation and faster iteration cycles in applied AI research, and why building your own harness is the key unlock for teams serious about scaling agentic workflows.
\*\*\*
**18:20 – Talk #2**
**Low code feature engineering in Zalando with Agentic support**
Ola Wahab — Zalando
Feature engineering at scale has traditionally been a high-friction process — days of infra setup, complex tooling coordination, and lots of boilerplate. Ola will walk through how Zalando is shifting to a low-code, configuration-driven approach where teams define pipelines declaratively, and how agentic coding has compressed the journey from feature discovery to production from weeks to days.

Lousy & Lazy SC - Mixed Friendly Football
Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or not so talented? Are you tired of insecure bros who only want to show off their skills? **Then [Lousy & Lazy Football](https://www.instagram.com/landlsc/) is the right thing for you!**
We are a group of friendly people who just want to have a relaxed kick. All genders, ages (+18) and nationalities welcome. **Feel free to join the waitlist even if it seems long - sometimes we make the event larger and play on two pitches (24 players, four teams) or even three pitches (36 players, six teams), depending on demand.**
Note: **We do not allow high-studded football boots during our sessions.** To avoid injuries, we only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/).
Rules for lazy & lousy football
1. **Don’t be competitive**
2. **No hard tackling/sliding challenges**
3. **Support new players by giving them the time and space to play the ball**
4. **Don’t dribble past multiple players (trying to take on a player is fine but at no point should you be trying to dribble past multiple players).**
5. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.**
6. **Rotate the goalkeeper**
7. **Be a teamplayer**
Waiting list:
This meetup is for members of the Lousy & Lazy Sport Club. If you want to try out our lousy & lazy sport events, you can do a trial run (Probetraining).

Chitta Walks - Awareness in Motion
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.**

Conversacion en español (en persona)
While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome!
Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here.
Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings.
Find us on our [Facebook group](https://www.facebook.com/share/g/1EKw86WJCp/?mibextid=wwXIfr).
Columbus Arduino Raspberry Pi Enthusiasts (CARPE) (Check Location)
Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration!
This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired.
**New to electronics or curious about tinkering?**
You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building.
While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
