Join us for a hands-on workshop by Olena Kutsenko on Wednesday, February 25th from 5:30pm hosted by SPACE SHACK Coworking! **Venue:** **SPACE SHACK Coworking** Akazienstraße 3A, 10823 Berlin, Germany **Agenda:** * 5:30pm – 6:00pm: Welcome, Food/Drinks & Networking * 6:00pm - 8:30 pm: Workshop by Olena ** So that Olena has an idea of audience priorities, please fill in the [pre-workshop form](https://docs.google.com/forms/d/e/1FAIpQLSeJsBjgkL2EXvPtBScXtI5yAv6N9gFg64QmMajMUiMmaPllxQ/viewform?usp=sharing&ouid=117948459316244235775) when you can (no personal info is collected)** ** Speaker & Workshop Details:** Olena Kutsenko, Staff Developer Advocate, Confluent **Hands-on workshop: real-time flight data streaming, anomalies, predictions, and visualizations** **Workshop Overview** In this hands-on session, we'll build a real-time analytics pipeline using flight data and modern streaming tools — step by step, and without hand-waving. We'll start by streaming data into Apache Kafka using Confluent Cloud, process it with Apache Flink, and land it in Apache Iceberg using Tableflow. From there, we'll query the data with Trino and turn it into dashboards using Superset. Everything runs in a practical setup you can reproduce later, including Docker and cloud-managed services. Along the way, we'll also look at anomaly detection and simple predictions using built-in functions, so you can see how real-time insights can be added without building custom ML pipelines or complex models. This session is all about doing, not slides. You'll see how the pieces actually fit together, what decisions matter in practice (regions, credentials, formats), and how to go from streaming data to analytics in a way that scales. If you're curious about real-time analytics, Kafka + Flink in the cloud, or how streaming, analytics, and lightweight predictive use cases come together in the same pipeline, this workshop will give you a clear, working mental model — and code you can take home. No prior experience with Kafka, Flink, or Iceberg required! Just bring your curiosity and a laptop! **Technical Prerequisites:** To make sure you can get hands on during this workshop, please make sure the following are installed on your system (**Make sure your bring your laptops!)** **1\.

This is "***New Members Night***." If you are one of the many folks on the fence about coming to your first wine tasting with the *Hilliard Wine Club*, this is the night to come. There will be many other new people, so you won't be alone. And the regulars will be there to help make you feel welcome. We're a relaxed and warm group. We hope to see you. **SIDE NOTE:** New members are welcome to ALL our Friday night wine tastings, but this night is a special overture to those who don't want to feel that they are the only new person in the room. Don't worry. You won't be. And don't hesitate to RSVP to other events. **OLD MEMBERS NOTE**: Hey Old Members! You're not excluded from this event. We expect to see you there to help make the new members feel welcome. **Sample 4 different wines** this Friday for $15 (*Cash or Venmo only please*). Glasses are provided. Bring a snack to share. Bring a bottle to share if you care to. See all the details below for the Hilliard Wine Club Wine Tasting. In Person. In Real Life. Actual Wine from glass bottles with corks and everything. **Wine**: Tastings will be $15 for four samples as always. And you are welcome to bring a bottle of your favorite wine to share with others. Participation in the wine tastings is optional. But since you’re going, I will buy enough wine to cover you. If you bring your own wine and do not participate in the tasting you will only pay $10 to cover the door charge. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. **Glasses**: …will be provided. Please note that after the wine tasting, the glasses need to be returned to the boxes at the service table. Please be gentle, our glasses are fragile. Uh, they are made of glass! **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **Extra Wine**: After everyone has had their samples, we remove the pouring spouts and any remaining wine is poured freely to whomever wants it. I hate having leftover wine. **Queen of Hearts**: The Queen of Hearts raffle is a fundraiser for the club and a Barnum and Bailey type extravaganza - minus the dancing ponies, clowns, and actual circus. Bring your ***cash*** as the Queen does not accept American Express or other plastic. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host*
