**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2).

Awaken your body and mind as breath meets movement in a flowing, dynamic practice. Each session combines sequences of postures (asanas) with mindful breathing, building strength, flexibility, and balance. Whether you’re a beginner or have experience, this class will help you: improve mobility and posture, increase core strength and stamina, release tension and stress and connect breath with movement for mindfulness. Expect a thoughtful warm-up, flowing sequences, and a calming cooldown to restore energy. Sound bowls deepen relaxation in Shavasana with calming, healing vibrations. Step onto your mat, move with your breath, and leave feeling both energised and centred. This class is held in English. Bring your own mat or use one of ours.

**\*\*\* SIGN-UP on LUMA ONLY to get the address and attend!\*\*\*** **A Small Update for 2026** Thanks to those who took the LSLab survey. We learned a lot, and will use that feedback to continue creating a dynamic, safe and relevant learning community. Starting now, there will be a few small changes, beginning with this meet-up, so we can test as we go. So after many years on Meetup, LSLab Berlin is evolving. **From now on:** * Events will be announced inside Meetup, but *organized on LUMA* (**Link to sign up here:** [https://luma.com/vs42c5uc](https://luma.com/vs42c5uc)). * We’ll charge a small participation \*fee when you sign up. * Sign-ups to the email so updates can come from LUMA - no spam, just updates on LS events (address or date change, opportunities to be on the design team, events relevant for LS!) This helps: * Cover admin and multiple platform costs * Support behind-the-scenes coordination * Encourage attendance commitment * Give our hosts a more accurate guest count It’s about sustainability and respecting everyone’s time. We will see how it all works and make adjustments as we go. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* **Here we come, Deutsche Bahn** 🚆 We’re on fire in 2026, our second Lab this year and we’re not even out of Q1. As always, we are looking to make it: fun, practical, slightly surprising. **Theme:** TBD – our design team meets next week and we’ll post the theme and string as soon as it’s ready. **Our Host:** We’re excited to be hosted by Deutsche Bahn. Their space gives us plenty of room to move, work in small groups, and play. **What Happens at an LSLab?** Every Lab includes: ✔️ Networking & connecting ✔️ Giving and Getting Help ✔️ A thoughtfully designed Liberating Structures “string.” ✔️ Action planning We don’t do long debriefs during the session, on purpose. LSLab is a practice space, mostly for the Design Team, and the participant, you, learn by doing! By participating. By seeing what it’s like to be part of the collective intelligence. Questions are welcome during the break and after we close. **New to Liberating Structures?** Totally fine. You don’t need experience. We’re a mix of beginners, experienced facilitators, agilists, OD/L&D folks, coaches, leaders, and curious humans who want better collaboration. You’ll learn by being part of it. **Language** Intro and instructions are in English. Small group work can happen in whatever language works for you. Mark your calendar. Come practice. Bring your curiosity. See you there, Sylvia \*If you are facing financial hardship or have been laid off, we'll waive your fee. Just reach out to us and let us know. We want you to be able to contribute and connect with us!

Looking forward to seeing many of you in person again soon. 🚀

**A place to meet sound, without maps** Facilitated by **Vesti Gium (they/them)** Everyone enters as they are. No score. No threshold of skill. We follow the room, moment by moment— listening, nudging, letting the music find itself. A breath, a shoelace, a laugh, a footstep— each carries weight. Silence is welcomed; noise is celebrated. There are no wrong directions here. We practise a listening that reaches outward and inward: to ourselves, to one another, to the space we shape together. That is where the music begins. * 🌀 Bring a voice, an object, an instrument, a movement—or nothing at all. * ✨ **Priority given to FLINTA folks and people with migration backgrounds.** * 🎧 No experience needed.

**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** *[Qase](https://qase.io) is presenting the **eleventh** Meetup on Quality Engineering in Berlin.* *This time, we’re bringing you three deep-dive talks — all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Mitesh Patel\, Technical Consultant \- Scientific Instruments @ Altum Solutions: *Food QA: Testing Tasting*** On this fine evening, we shall enjoy some food … and also learn why we enjoy it. Because tasting is really a form of testing for our brains — wetware QA in essence. But how do we reformulate this wetware testing into those familiar realms of software and hardware testing? It is not as simple as exchanging taste buds for test suites and bites for bytes. Just ask Big Food which spends billions on this same question: How can computers do taste tests like humans? Guided by the example of an ML/AI-powered scientific instrument for chemical analyses, namely, a spectrometer, this session addresses this question and explores the broader topic of QA in the food industry. Discover how food companies scale testing across scientific software, device hardware, and food/human wetware. So grab a spoon for this insider scoop on QA for food. **2\. Vitaly Sharovatov\, developer advocate @ Qase: *QA Myths Busting: A Practical Guide to Higher Quality*** Have you ever felt the urge to increase the amount of testing or hire more testers, thinking it would improve product quality? As a tester, have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers? Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. In this talk, I will present the myths I once believed, explain the dangers they pose to both teams and products, and demonstrate how they should be debunked and overcome. **3\. Asya Isakova\, Co\-Founder @ TECH_Connect: 𝘌𝘢𝘳𝘯 𝘛𝘳𝘶𝘴𝘵\, 𝘒𝘦𝘦𝘱 𝘠𝘰𝘶𝘳 𝘑𝘰𝘣** The job market is wild: it’s hard to get hired, and sometimes even harder to stay hired. In a new role (or a new team), one of the fastest ways to reduce uncertainty and accelerate collaboration is to build trust quickly. But how do colleagues and managers decide you’re trustworthy? It’s rarely just about closing Jira tickets or moving cards on a Kanban board. People assess trust through patterns of behavior: what you do, how consistently you do it, and how do you act towards others. In this talk, you’ll learn an evidence-based approach to building trust at work using three practical components: integrity, reliability, and benevolence. We’ll unpack what shapes people’s trust judgments (including context, risk, and prior experiences) and translate research into concrete behaviors you can apply immediately: especially in multicultural and cross-functional teams.

Dieses Meetup ist Teil einer weltumspannenden Initiative, um Bewusstheit, Mut und Warmherzigkeit (Awareness, Courage and Love) im Umgang mit uns selbst und in der Begegnung mit anderen zu üben. Die Idee zu dieser Initiative stammt von Mavis Tsai, PhD, der Mitbegründerin einer relativ neuen psychotherapeutische Richtung namens Functional Analytic Psychotherapy (FAP). In den ACL-Meetups sollen diejenigen FAP-Grundsätze, die sich in der Psychotherapie als besonders wirkungsvoll herausgestellt haben - nämlich die offene und warmherzige, authentische Begegnung - mit möglichst vielen Menschen geteilt werden, seien es Partner, Verwandte, Freunde, Klienten, Nachbarn oder sogar gänzlich Unbekannte. Wir treffen uns wieder vor Ort in Neukölln! Sowohl bekannte Gesichter als auch neue Teilnehmer:innen sind herzlich willkommen! Ladet gerne Menschen ein, denen ihr Nähe zuteilwerden lassen möchtet. Ihr könnt jederzeit von der Möglichkeit Gebrauch machen, euch mit Gästen anzumelden. Bitte seid pünktlich. Wir schließen den Raum spätestens um 16:05 Uhr, um einen sicheren Rahmen zu gewährleisten. Wenn ihr es nicht pünklich schafft, seid ihr gern bei einem unserer nächsten Treffen willkommen. Zum Hintergrund der ACL-Meetups: In den Meetups üben wir, mit unseren verletzlichen Seiten in Kontakt zu treten, uns anderen Menschen gegenüber authentisch zu zeigen, und Nähe in zwischenmenschlichen Begegnungen zu schaffen. Um Nähe und Verbundenheit mit anderen Menschen erleben zu können, braucht es: Bewusstheit (Awareness) der eigenen Bedürfnisse, Wünsche, Ängste, Vermeidungstendenzen und Unzulänglichkeiten, Mut (Courage), sich mit all diesen Teilen unserer selbst zu zeigen und dabei das Risiko einzugehen, sich der Beurteilung und möglichen Ablehnung anderer auszusetzen, und Warmherzigkeit (Love) im Umgang mit uns selbst und anderen, sodass wir unserem Mut und unserer Verletzlichkeit mit Wohlwollen und Mitmenschlichkeit begegnen und uns gegenseitig ermuntern, uns zu öffnen. Inzwischen gibt es Meetups an mehr als 90 Orten in 28 Ländern auf 5 Kontinenten mit weltweit über 10.000 Mitgliedern. Wir (Mathias Funke und Ralf Steinkopff) organisieren die Berliner Gruppe. Es gibt ca. 6-8 Treffen im Jahr, in denen wir die Prinzipien von ACL miteinander erfahren können.

One of the most valuable parts of this community is the opportunity to think out loud with other product professionals. This session is built for exactly that. As we wrap up the quarter, it’s a great time to pause and reflect. What’s on track? What needs adjustment? Where could a small shift create bigger impact? Join fellow product professionals for a focused, interactive conversation designed to help you recalibrate for the next quarter. You’ll have the opportunity to share where you are, hear how others are thinking through similar challenges, and gain fresh perspective you can bring back to your team and organization. We’ll gather at 8:00AM, with discussion starting promptly at 8:15AM. 📍 First Watch - 7227 N High St Located in: The Shops at Worthington Ample parking is available. Food and beverages will be available for purchase. Start your morning with clarity and connection — we hope to see you there! ☀️

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

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.
