We are back in the c-base! Do you already run NixOS and want to talk to other people or want an introductory session with some NixOS users. Just bring your machine! Usually there are no topics, we just sit in front of our computers, talk about stuff, debug some problems or review some PRs on nixpkgs. There are drinks usually available from the c-base bar. If you can't find us. just ask around or ask in irc (#krebs on hackint)

Ok everybody, it's 2026, and after taking a break for the holidays, games are starting up again as usual. We'll meet, have a beer, and play a round of cards against humanity. Laughs will be had, groans will be groaned, beer will go down the hatch. This event is public, and prior experience with the game is not required. You are not required to drink alcohol, but please note that we are crashing a bar (cash only), so a beverage purchase or two is appropriate and necessary for us to maintain their goodwill. See you there!

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!

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.**

Layoffs, longer job searches, and rapid shifts driven by AI are leaving many professionals wondering about their next move. In this interactive AMA session, Valentina Scipione will answer your questions about careers in tech. Bring anything you have been wondering about, for example: * navigating the current job market * what hiring managers actually look for * career transitions within tech * job search strategy * how AI may reshape roles in data and engineering No slides. Just your questions and an open conversation. **Speaker:** Valentina Scipione **Bio:** Valentina Scipione is a Career and Leadership Coach, Engineering Manager, and hiring manager with a background in Astrophysics and more than a decade of experience in software engineering and quality. Based in Berlin and co-organiser of the PyData Berlin community, she brings together leadership experience and professional coaching to help tech professionals build more fulfilling careers with strategy, not autopilot. **Talk 2: Solving real life problems with basic Python** **Abstract:** 2 years ago I had the privilege and pleasure of meeting an amazing person who invited me to join the Python en Español community. This community is mainly aimed at people who have 0 to no knowledge about the language and they want to learn. The recurring problem for many of these practitioner is to find good real life examples to practice their skills. Did you know that you can solve 90% of business problems with only prints and inputs? well, maybe that was a lie but not far off from the truth. In this talk I want to guide you on how you can solve a real life case scenario of a business wanting to adjust the prices of their articles base on real time demand. Starting with a few variables an input and a print and slowly grow into a real time system consuming from different sources, to answer the hardest question there is. Was it worth it? or should we have stopped at reading from files 7 iterations ago? **Speaker:** Eric Rishmüller **Bio:** Eric works as a Lead Data Engineer at Thomann Musikhaus. He has been living in Berlin for the past five years and is originally from Argentina. Eric started sharing his passion for Python seven years ago and is quite active in Spanish-speaking Python communities. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each).

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!

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

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.
