## Details The title of the event is a paradox! Read in silence and then discuss with like-minded folks! :-) 📝 **How does this work?** We will meet in the Bartley's Restaurant area from 7:00 PM to 8:15 PM for silent reading and followed up by discussion. **During silent reading, you're expected to remain silent and read.** Please bring your headphones and refrain from the discussion during the first one hour in the area. 👥 **Socialising** After an hour, at 8:15 PM, we'll discuss and socialize about the book you're reading. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! Feel free to join at any point during the event. The event is indoors, hopefully, we can continue the tradition of the silent reading in the winter! **📌 Helpful Tips and Notes** * Bring headphones to block out surrounding noise * I will post a comment on the event page when I arrive to indicate where we're seated, so everyone can find us * If you prefer to skip the silent reading, you can join directly at the bar at 8:15 PM ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. It may be small but don't hesitate to reach out to me. Looking forward to meeting you all 😊

It's National Bike Week from Saturday 9th – Sunday 17th May 2026. Join us at Tog on the afternoon of Saturday 16th May from 3pm, for a bicycle maintenance and advice meetup. Many of us at Tog are keen cyclists and e-bikers. Tinkering with our bikes is business-as-usual for us. We have plenty of tools at Tog to do most basic bicycle maintenance, cleaning, lubrication & adjusting. Even if your bike is running well and you just want to pop in for a bit of advice, we'd be delighted to see you. We'll be continuing our Saturday from 7pm that same day with our regular monthly Open Social event. You're welcome to stick around or drop back in later. Expect the usual pizza, good chat and craic.... and of course we'll be willing to talk all things cycling.

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!

**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.

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
