The common wisdom goes: data is either transactional or analytical, and workloads are OLTP and OLAP-shaped to match. The reality of generating and using data is different, and often we need a bit of both. The pg_lake extension brings OLAP workloads to OLTP Postgres. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. **I Didn't Know Postgres Could Do That!** by Robert Treat, Principal Database Engineer at AWS and PostgreSQL Major Contributor. PostgreSQL is often thought of as "The Database for DBAs", but what more and more developers are finding out is that what makes Postgres "The Worlds Most Advanced Open Source Database" is its wide array of features, many of which are really geared towards engineers building applications on top of Postgres. In this talk, we'll look at some of the features in Postgres you may not have seen in other database systems, and talk about how you can make use of those features in your applications. Queries, indexing, data types, and more will all be up for discussion as we show you examples of just what Postgres can do.

Come join us for a gentle yet powerful Seitai group practice — a space where silence, breath, and spontaneous movement meet. This is a donation-based event, so you’re free to contribute what feels right (from 0€ to (your choice)€). ✨ What is Seitai? Seitai (整体) is a Japanese practice that helps you reconnect with your body’s innate intelligence. Through subtle awareness and guided techniques, you’ll be invited to: Listen deeply to your body through Yuki (a meditative, hands-on practice of sensing and following the breath). Release hidden tension with Katsugen — allowing involuntary, spontaneous movements to arise naturally. Find balance in stillness and movement, letting your body recalibrate itself in surprising ways. Seitai is not about control or forcing; it’s about giving voice to the movements your body has been waiting to express. Sometimes this brings ease, clarity, and lightness. Sometimes it stirs up dizziness, discomfort, or emotions. Every experience is valid — and you are always free to pause or leave at any time. 🌌 Why join? Discover a practice that many find deeply transformative. Create space for release, renewal, and vitality. Explore in community, whether you’re a curious first-timer or already familiar with Seitai. 👕 Practical details Wear comfortable clothes and bring a towel and water to stay hydrated. Bring openness and curiosity. Watchers are welcome — you can simply observe, or dive into active practice. The session is guided, but the real teacher is your own body. ✨ Learn more: 🎥 Watch a short video: https://youtu.be/KF7agFE1zss?si=6UhmjwaIAfBo-_Op 📖 Read more about Seitai: https://seitaibarcelona.com/what-is-seitai/ Everyone is welcome, whether you are completely new or already familiar with Seitai. Bring comfortable clothes and an open mind. 💰 This event is donation-based, supporting the space and allowing us to keep offering it. Private one-to-one sessions are also available at an affordable price. 🌿 Step into silence, breath, and spontaneous movement — your body knows the way.

Dies ist eine Veranstaltung auf Spendenbasis, du kannst also frei beisteuern, was sich für dich richtig anfühlt (von 0€ bis (deine Wahl)€). ✨ Was ist Seitai? Seitai (整体) ist eine japanische Praxis, die dir hilft, dich wieder mit der angeborenen Intelligenz deines Körpers zu verbinden. Durch subtile Achtsamkeit und angeleitete Techniken bist du eingeladen: \*Tief auf deinen Körper zu hören durch Yuki (eine meditative, praktische Übung des Erspürens und Folgens des Atems). * Verborgene Spannungen mit Katsugen zu lösen – indem du unwillkürlichen, spontanen Bewegungen erlaubst, ganz natürlich zu entstehen. \*Balance in Stille und Bewegung zu finden, während sich dein Körper auf überraschende Weise selbst neu ausrichtet. Bei Seitai geht es nicht um Kontrolle oder Zwang; es geht darum, den Bewegungen eine Stimme zu geben, auf deren Ausdruck dein Körper gewartet hat. Manchmal bringt dies Leichtigkeit, Klarheit und Entspannung. Manchmal wirbelt es Schwindel, Unbehagen oder Emotionen auf. Jede Erfahrung ist gültig – und es steht dir jederzeit frei, eine Pause zu machen oder zu gehen. 🌌 Warum teilnehmen? * Entdecke eine Praxis, die viele als tief transformierend empfinden. \*Schaffe Raum für Loslassen, Erneuerung und Vitalität. * Erkunde die Praxis in der Gemeinschaft, egal ob du neugieriger Anfänger bist oder bereits Erfahrung mit Seitai hast. 👕 Praktische Details \*Trage bequeme Kleidung und bringe ein Handtuch sowie Wasser mit, um hydriert zu bleiben. * Bringe Offenheit und Neugier mit. \*Zuschauer sind willkommen – du kannst einfach nur beobachten oder direkt in die aktive Praxis eintauchen. * Die Sitzung wird angeleitet, aber der wahre Lehrer ist dein eigener Körper. ✨ Mehr erfahren: 🎥 Schau dir ein kurzes Video an: https://youtu.be/KF7agFE1zss?si=6UhmjwaIAfBo-_Op In diesem Video [00:16] wird Seitai als eine japanische Kulturform beschrieben, die den Organismus wieder in Ordnung bringt („Seitai“ bedeutet „Körper in Ordnung“). Es basiert auf der Beobachtung der natürlichen Lebensenergie und nutzt Bewegungen wie Katsugen Undo [00:32], um die Vitalität zu fördern. 📖 Lies mehr über Seitai: https://seitaibarcelona.com/what-is-seitai/ Jeder ist willkommen, egal ob du völlig neu bist oder Seitai bereits kennst. Bringe bequeme Kleidung und einen offenen Geist mit. 💰 Diese Veranstaltung basiert auf Spenden, um den Raum zu unterstützen und es uns zu ermöglichen, dieses Angebot weiterhin aufrechtzuerhalten. Private Einzelsitzungen sind ebenfalls zu einem erschwinglichen Preis verfügbar. 🌿 Tritt ein in die Stille, den Atem und die spontane Bewegung – dein Körper kennt den Weg.

Hallo, es ist wieder so weit, der zweite Freitag im Mai ist diese Woche! Deshalb habe ich im Neffes draußen im Innenhof für uns reserviert. Wenn das Wetter schlecht werden sollte, haben wir die Ecke vor dem - ausgeschalteten - Fernseher für uns :-). Ich freue mich schon, euch wieder persönlich zu sehen! Und hier der übliche Ankündigungstext: Unser zweimonatliches Treffen steht wieder an! An jedem zweiten Freitag eines ungeraden Monats treffen wir Selbständige, Unternehmer und Freiberufler aus der IT uns wieder um 19:00 Uhr im Neffes. Bei einem gemütlichen Zusammensein werden wir uns über fast alle Themen unterhalten. Der Schwerpunkt liegt dabei auf den beruflichen Themen. Z. B. wie gehen andere mit den Kunden und deren Mitarbeitern um, was sind die neuesten Insider Infos von den verschiedenen Unternehmen, wie sieht es bei den anderen mit den Einsatzorten und Arbeitsbedingungen aus und vieles mehr. Es wird wie immer ein interessanter Abend mit einem umfangreichen Erfahrungsaustausch werden, der einen auch beruflich weiterbringt. Mit dem DBITS e.V. wollen wir die Anerkennung von IT-Freiberuflern in der Gesellschaft und Politik vorantreiben, dort gibt es leider noch einen sehr großen Aufhol- und Aufklärungsbedarf und damit viel zu besprechen und zu erfahren. Des Weiteren bietet uns der Verein ein breites Netzwerk an Leuten mit den gleichen Zielen und Problemen. Aber wie gesagt, das Ziel ist ein schöner, informativer Abend, es gibt kein Mitgliederzwang. Nimm teil, wir freuen uns auf dein Kommen! Viele Grüße und ich freue mich schon auf ein Treffen am nächsten Freitag!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

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.
