Was ist Embodied Dating? ## Die Idee ist *simpel.* Wir lernen Menschen am schnellsten kennen, wenn wir mit ihnen wirklich in Kontakt kommen. Nicht digital. Nicht über Smalltalk. Sondern **körperlich**, direkt und *ehrlich.* Denn unser Körper weiß deutlich schneller, ob es passen könnte. Und bevor du investierst, um am Ende wieder enttäuscht zu sein, probier doch mal was **Neues**. Und das beste: Selbst wenn es nicht funkt, wirst du eine **wertvolle Erfahrung** gemacht haben!

Hello Gophers, Welcome back for another year of Go talks and networking! Would your company like to host our meetup? Let us know! If you'd like to give a talk - submit your proposals here: http://goo.gl/forms/54YvJT223F All talk formats work: short talks (5-10 min) as well as regular length (25 min). If you have more ideas - talk to us at the Gophers slack: https://invite.slack.gobridge.org/ in the #berlin channel, and follow us on twitter: https://twitter.com/gdgberlingo **Speakers**: *Simon Schulte* is a Tech Lead with nearly a decade of experience building scalable backend systems across fast-paced product companies. With a background in business informatics and a passion for Golang, cloud infrastructure, and DevOps, he has spent his career solving complex engineering challenges. He is particularly excited about leveraging AI and LLM workflows to eliminate the tedious, repetitive work that slows developers down — think tech debt, boilerplate, and documentation — so engineers can spend their energy on what actually moves the needle. For Simon, AI isn't about replacing developers; it's about giving them back their time. *Daniel Peralta Madriz* is a backend engineer from Costa Rica with around 6 years of experience working with Golang, although, sadly, he's been spending most of his time lately working with Node.js :(. He is interested in distributed systems, scalability, and developer experience, and is currently experimenting with how to leverage LLMs to safely and autonomously execute repetitive tasks. *Michael Morgen* is a Platform/infra engineer by day, runtime and network optimizations by night. Join in person at: **Talon.One** Talon.One is the incentives engine behind 300 of the world’s most-loved brands, unifying loyalty and promotions on a single flexible platform. Their customers run millions of real-time incentive decisions across markets, channels, and use [cases.As](http://cases.as/) incentives become more strategic than ever, they are continuing to raise the bar for what businesses can build and how fast they can build it Wiener Str. 10, 10999 Berlin https://maps.app.goo.gl/8eMjgWes1E4TBA3c7 or virtually at: https://www.youtube.com/live/qh__TQ1bMF0?is=hw21pk0ZE3HGyaaT *** Agenda 10:49 PM: Networking Networking over drinks and food 7:30 PM: Welcome Welcome words from the organizers 7:35 PM: Talk 1: Go-ing Against the Chaos: Deterministic LLM Workflows / Daniel Peralta Madriz (Backend developer) & Simon Schulte (Techlead of Webhooks and Notifications) @ Talon.One LLMs are powerful, but “it works most of the time” isn’t good enough for production. In this talk, we’ll walk through how to design deterministic workflows around non-deterministic models using Go. From structured iteration loops to validation steps and guardrails, you’ll learn how to move beyond prompting and start engineering reliable LLM-powered systems 8:10 PM: Announcements and break Announcements, HR lost & found, open mic 8:30 PM: Talk 2: About Go Memory Allocator / Michael Morgen, Platform/infra engineer @ Mirantis A short talk about how Go gives memory to your program. We will look at the main allocator parts, why small allocations are usually fast, when Go asks the OS for more memory, and a couple of simple examples where this knowledge helps performance. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-may-golang-meetup-1/.

Berlin ICT Day Traders Community A community for serious day traders in Berlin focused on ICT concepts, liquidity, market structure, and disciplined execution. This group is designed for traders who already have market experience and are actively working toward consistency and profitability. It is not a beginner group, a signal-selling group, or a course promotion platform. The goal is to build a strong local network where traders can exchange ideas, review setups, discuss psychology, share lessons learned, and help each other improve in a professional and honest environment. I’ve been trading since 2020 and, like many traders, I’m still working toward long-term consistency and profitability. One of the reasons I created this group is to connect with like-minded traders who are serious about growth and continuous improvement. This will be our first meetup, and the goal is simply to meet other serious traders in Berlin, have valuable conversations, exchange ideas, and see how we can grow this community together over time. If anyone has good suggestions for a suitable meetup spot in Berlin — especially a quiet café, coworking space, or place with a screen/projector where we can comfortably discuss charts and setups — feel free to share your ideas. If you value honest discussions, discipline, and a professional mindset toward trading, you’re welcome to join us. For any suggestion insta : mnq_blnn

**Liebe Finanzfreunde,** 🌞🌳 Was gibt es Besseres, als sich an der frischen Luft zu bewegen und gleichzeitig über spannende Themen rund um Finanzen zu sprechen?

Wir freuen uns darauf, mit euch einen inspirierenden Abend zu verbringen. **Treffpunkt:** Stülerstraße 8-10, 10787 Berlin Wir treffen uns draußen in der Nähe der Koreanischen Botschaft und dann laufen zusammen Richtung Tiergarten. Beste Grüße, Euer Aktien für Alle Team ========================================== **Wer wir sind:** Wir sind eine vielfältige Gruppe von Menschen, die entdeckt haben, dass strategisches Aktienhandeln für jeden zugänglich ist. Unser Ziel ist es, unsere gemeinsame Erfahrung zu teilen und Anfänger im Aktienhandel zu inspirieren, sich sinnvoll und emotionsfrei zu investieren. Wir glauben fest an das Konzept des gegenseitigen Lernens – indem wir dir helfen, lernen auch wir von dir, und schaffen so eine Win-Win-Situation für alle. **Was wir glauben:** * Erfolgreiches Aktienhandeln ist keine exklusive Domäne für Finanzexperten. * Das Verstehen von Aktien und das Treffen informierter Anlageentscheidungen ist für jeden erreichbar. * Du benötigst keinen Abschluss in Betriebswirtschaft, um die Prinzipien der Wertanlage zu verstehen. * Technische Aktienanalyse ist nicht nur für Finanzprofis gedacht; es ist eine Fähigkeit, die du erlernen kannst. **Über die Meetup Gruppe:** Shuying hat Mitte 2023 selbst ihren Weg zur erfolgreichen Anlegerin gefunden – von frustriert und überfordert zur begeisterten Aktieninvestorin mit Fokus auf Chartanalyse. Begeistert von die Methode von Raik Mandel gründete sie diese Meetup-Gruppe, um andere auf ihrem Weg zu mehr Selbstvertrauen, Klarheit und finanzieller Freiheit zu unterstützen. **Über Raik Mandel:** Raik hat mehr als 25 Jahre Erfahrung als Bauunternehmer, Immobilieninvestor und Aktionär. Seine Leidenschaft hat sich inzwischen mehr auf die Börse verlagert, da dies weniger Zeitaufwand erfordert, flexibler ist und auch in fallenden Märkten Gewinne ermöglicht. Er hat sich auf einfache Aktienanalysen mithilfe der Chartanalyse spezialisiert. Raik war langjähriges Mitglied im IIC (Immobilien Investment Club), ist Mitglied im IVD (Immobilien Verband Deutschland), im VTAD (Vereinigung technischer Analysten Deutschlands e. V.).

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.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City. He has worked there for 17 years, serving previously in the roles of Data Analyst, Programmer, and Operations Coordinator.

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!

Dear Illinois Prairie PUG members, Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes. Our new meeting place is **Chicago Innovations at 1 W. Monroe**. *Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres *Speaker*: Elizabeth Christensen, Snowflake *Talk Description* The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack. 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. pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris. *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:20 - Hettie D. Data warehouse history overview 6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres 6:50 - 7:00 Q&A 7:00 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. You will notice the change in the RSVP form. We are thankful to our hosts and promise to be responsible. We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). We do not want to waste food, so please indicate your dietary preferences.
