He's back! The inventor of EventStorming is once again joining the Berlin Collaborative Modeling Meetup for an evening of massive learning, massive laughter, and no doubt a massive number of sticky notes. Here is the agenda: **Collaborative Reverse Roadmapping** We'll put future events on a timeline to build the future we want to happen and make it tactically sound. We'll leverage ideas from * EventStorming (surprise!) * Futurespective * Traditional planning And we'll explore a tool that will enable strategic planning and overcome deadlocks. This is a rare opportunity to spend time with a true thought leader in the DDD community and the person who contributed to the world the whole premise of our meetup. He's full of insights and stories, wit and wisdom, and we are lucky to have him drop by to share them with us. Don't miss this one! **Please do not RSVP if you do not intend to come. For this event only, we have to limit attendance.** As always, everyone is welcome. You don't need to be a software engineer to participate. In fact, it would be great to have more people who aren't software engineers. We're here to solve problems cross-functionally, not get into implementation details. As long as you care passionately about getting things right, then you belong here! This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

RSVP on Luma: https://luma.com/2axg6eyy Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles — whatever you’d like to spend a quiet hour with. All projects and all participants are welcome. ​This year is about creating more — quietly, consistently, imperfectly — and shaping environments that support that. If you’re building something of your own, you’re especially welcome here. ​We’re building a community of readers and creators who value depth, presence, and shared silence. The magic isn’t just in the quiet hour — it’s in the people who return and make it feel like a familiar room. ​(Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) ​This quiet ritual unfolds at **W66 Café**. ​There’s no entrance fee, but please order at least one item from the café and don’t bring outside drinks 🙂 ​No assignments. No pressure. No productivity race. Just a shared hour of intentional silence, followed by relaxed conversation. 🕰 Our Agenda ​**10:30 – 11:00** Arrivals, ordering drinks/food, light social time ​**11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) ​**12:00 – 12:30** Optional socializing — share what you were reading or creating, or simply continue in quiet focus. ## **​🏡 House Guidelines** ​To keep this space calm and welcoming for everyone: ​• Silence during the focus hour (no calls or conversations) • Phones on silent mode • If using a laptop, please avoid meetings or audio — headphones welcome • Arrive before 11:00 if possible to minimize disruptions

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.**

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

Drake Lundstrom is presenting: Code Anywhere by Talking to your Phone Abstract: Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices?

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
