Zorba the Greek by Nikos Kazantzakis
Zorba the Greek by Nikos Kazantzakis
Thanks to everyone who joined for the latest event on Zora Neale Hurston’s *Their Eyes Were Watching God*. Unfortunately, I wasn’t able to attend myself as I was ill, but I’m very glad to hear that the discussion went well. A special thanks to Clark for sending me the information about which book was chosen as the next one. The next book to read is the Greek classic *[Zorba the Greek](https://en.wikipedia.org/wiki/Zorba_the_Greek)* (1946) by [Nikos Kazantzakis](https://en.wikipedia.org/wiki/Nikos_Kazantzakis). My apologies for putting the next event up later than usual. Set on the island of Crete, the novel follows an intellectual narrator who meets the larger-than-life Alexis Zorba — a man driven by instinct, passion, and a deep love of life. What unfolds is both a philosophical and deeply human story about freedom, friendship, and what it means to truly live. A short description of the book reads: *A classic of modern Greek literature, Zorba the Greek contrasts the life of the mind with the life of action, as the narrator is drawn into Zorba’s vibrant, impulsive worldview. The novel explores existential questions about joy, suffering, and the human condition — all through the unforgettable character of Zorba.* You can read more about the book on Wikipedia [here](https://en.wikipedia.org/wiki/Zorba_the_Greek), find it on Goodreads [here](https://www.goodreads.com/book/show/53639.Zorba_the_Greek) and listen to it as an audiobook [here](https://www.youtube.com/watch?v=vO5Ij2fbkpc). There is also a famous film adaptation from 1964, *[Zorba the Greek](https://www.justwatch.com/uk/movie/zorba-the-greek)*, starring Anthony Quinn. The film was very well received and won three Academy Awards (including Best Supporting Actress and Best Cinematography), and was also nominated for Best Picture. It's not, however, that easy to come by, unfortunately. For other resources on how to get a hold of classic books, please see the *[About](https://www.meetup.com/copenhagen-classic-book-book-club/)* section on the front page of the group. We meet up on **Saturday, May 9th, at 4 p.m.** The location will be [The Garden of The Royal Library](https://en.wikipedia.org/wiki/Royal_Library_Garden,_Copenhagen). During the spring and summer months, we always meet outside here. If the weather turns rainy, we will simply move indoors. But fear not, we will be back at The Fireplace Lounge in autumn. Please remember to bring your suggestion for the next classic book to read. And, as always, please be mindful and respectful of each other, so that everyone feels welcome and appreciated. In the meantime, happy reading/listening/watching — or however you prefer to do it.

Where Am I Right Now?
Where Am I Right Now?
Feeling stuck, unsure, or just tired of thinking about “what’s next”? In this 90-minute interactive workshop, we’ll take a step back and look at your current situation—without judgment or pressure to have answers. Instead of trying to “figure out your whole life,” we’ll focus on something simpler: 👉 getting a clear snapshot of where you are right now You’ll explore: • What’s currently working (and what’s not) • Where your energy goes in daily life • Which area of your life feels most out of balance And most importantly: You’ll leave with one small, realistic step to improve your situation. 🧭 This session is part of a 6-part series, but it also works as a standalone workshop. No preparation needed. Just bring yourself.

Blue Lotus Ceremony
Blue Lotus Ceremony
This evening is for women who feel tired, overwhelmed or disconnected — and want to pause without needing to explain anything. When your mind is full, but you don’t want to analyse it anymore. When something inside doesn’t feel right, but words don’t help. This is a space where nothing needs to be solved. Through guided awareness, music and atmosphere, we will slow down the body and the breath, and bring attention back to simple sensations. You’ll be offered blue lotus tea — a gentle support that helps the body relax and makes it easier to stay present. You may leave with a quieter mind, a calmer body, and a clearer sense of how you feel. This isn’t therapy. It’s a guided experience. If you feel ready to go deeper, there will be a follow-up women’s circle. Date: May 9 Time: 18:00–21:00 Location: Masnedøgade 20, 2100 København Ø Duration: 3 hours Price: 350 DKK Reserve your place: [https://betal.mobilepay.dk/2htg1d](https://l.facebook.com/l.php?u=https%3A%2F%2Fbetal.mobilepay.dk%2F2htg1d%3Ffbclid%3DIwZXh0bgNhZW0CMTAAYnJpZBEwMUVLa0RiT2k5ckhIMGw3ZXNydGMGYXBwX2lkEDIyMjAzOTE3ODgyMDA4OTIAAR5eZJLTng-_GPEQwUMTws53_bLmlG5TCJ2Gwtlb21bYtl6-Dlwtzag_0GPdzw_aem_DmPunTLHl77z6eHqWHV3HA&h=AT4MAAsLAqh-GGDEqAb35QcYWw3kwUnOz-gaeiCerxImhIhh6p3UUDufTcW6d_-cfR__LWHB6mUvDQz7d88HNkjOeK-1NpOG8vc-z0HK1bw44dJIiikzrUhJM3xCcDwDkTA9rH9TTJ1JQ4QOYJ1Dk4ZQYDG_rg&__tn__=q&c%5B0%5D=AT7QEc315onoyOmQvGkGUVM5G9KJLj_pUb5__EoPPl-4No5JMMQOZnemYOz5gvR24snS_Jkeo1C-RhIk7S8byoX0LNuwF2doPJsvxzasPg6WjawN1am9krh2w0Ql2-hQ-kmYp-N_89Vlp6j8DnCarJ32C6HuvLUkpLQ) See less

Data & Analytics Wednesday - Mapping and Dashboards
Data & Analytics Wednesday - Mapping and Dashboards
**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.

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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!

CBusData - Practical AI for Power BI Developers
CBusData - Practical AI for Power BI Developers
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.
