A space where you can be curious without performing, open without oversharing, and social without exhausting yourself. 🌙 If you enjoy meaningful encounters that feel light but real — this evening is for you. ✨ Suggested Ice Breaker Question: “What makes a conversation feel easy for you?” Orga This meetup is donation based.

Kommt am 2. Montagabend im Monat ins Offene Wohnzimmer zum Open Draw! Raucht Euch auch manchmal der Kopf von zu viel PC-Arbeit? Der Asphalt der Stadt ist heute wieder viel zu grau? Ihr würdet am liebsten mal wieder wild auf einem Blatt Papier rumklecksen oder gedankenverlorene Linien zeichnen? Höchste Zeit zur Tat zu schreiten! Wir wollen in entspannter Atmosphäre die kreativen Zellen auf Volldampf fahren und uns der Inspiration überlassen. Mit Musik im Hintergrund sowie Wein, Tee und Snacks im Repertoire wird dann gekleckst, gemalt, gezeichnet, geklebt, geredet und gelacht. Das Ganze kann sehr ambitioniert stattfinden, aber genauso zum Hirn-abschalten dienen. Austausch, Bilderswapping und gegenseitige Tipps/Kritik sind sehr willkommen. Material stellen wir (Kreide, Bleistift, Wasserfarbe, Acrylfarbe, Pastellstifte, Kohle, Papierbögen, Spiegel, Postkarten, Zeichenbücher, Illustrierte). Sujet kann alles sein: Der/die Tischnächste, der letzte Traum, oder der Feldhase Dürers. Technik auch: Von (Selbst)portrait über Stilleben bis zur Comiczeichnung soll alles abgedeckt werden. Wir bieten jeden 2. Montag im Monat offene Treffen zum kreativen Arbeiten sowie gelegentlich technik- und themenbasierte Workshops an. Wie immer wird um eine Spende für Raummiete/Material von 5-10€ gebeten. Anmeldung: Katharinav.runnen@gmx.de

A small NEXUS gathering built around movement rather than discussion alone. This is for high-bandwidth Mavericks who spend most of their time in conceptual thought and need some physical counterweight. Why bouldering? Because it’s deliberate: short problems, full focus, and immediate feedback. You’re on the wall, solving something tangible. The mental noise drops instantly! Conversations happen naturally in between climbs. No pressure, you move at your own pace. Some exchanges stay light. Others go deep. Both are fine. This is not about athletic achievement. It’s about presence, recalibration, and being around people who don’t require you to shrink or translate yourself. Come as you are. Try some bouldering problems. Rest when needed, and engage where it makes sense. **Bring comfortable clothes and climbing shoes if you have them (rentals are available at the gym).** *Registration equals commitment. If you sign up, you show up. Read the group description first and decide consciously. For context about NEXUS, visit our* ***[website](https://thenexusformula.com)*** *and* ***[newsletter](https://news.thenexusformula.com)****.*

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).

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.

This is not an event, but an announcement that we are accepting new members.

Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor.
