Join us for a community-led developer event focused on **AI-assisted coding with GitHub Copilot**. This event brings together developers to explore practical workflows, real-world use cases, and hands-on experiences using GitHub Copilot. Whether you are new to GitHub Copilot or already using it, this event will help you better understand how to apply AI-assisted coding techniques in everyday development hosted at **adesso SE**. **Sessions & Workshops** 1. **GitHub Copilot in practise - Sandra Ahlgrimm** 2. **Let's create a tiny AI library together, Copilot powered - Johannes Bechberger** 3. **GitHub Copilot Hands-on workshop - bring your laptops!** **Location** [Prinzenstraße 34, 10969 Berlin](https://www.google.com/maps/place//data=!4m2!3m1!1s0x47a84e50ecd583e3:0xde16d03634776e3b?sa=X&ved=1t:8290&ictx=111) **Agenda** 17:30 - doors open 18:00 - warm welcome by JUG leader **Sandra Ahlgrimm** and **Andreas Voigt** from **adessoSE** 18:15 - first session 18:40 - second session 19:30 - workshop **Abstracts** **Let's create a tiny AI library together, Copilot powered** We all want to do it. When you want to integrate AI into your tools, what do you do? You add LangChain4j or SpringAI and run with it.

Hi everyone. We'll meet and play a relaxed game of ultimate in Volkspark Rehberge if the weather cooperates. Our games focus on having great team play, where the teams work together to advance the disk down the field. It's more important to work well together as a team than have a few star players get a point with lucky shots. For this reason, players of all skill levels (especially those who have never played) are welcome to join Bring plenty of water, shoes you can run in and comfortable clothing that can get a bit dirty. Although we're an established group, newcomers are always welcome. After the game we try to spend some time together and have fun. Finding us: We meet in this big grassy area, it's a short bike ride from the subway stop Rehberge on the U6 or Amrumer Strasse on the U9. It can be a bit tricky to find the first time, so we've got a few methods to help out (don't trust the meetup map pin, it often shows some point in the park, not the exact spot where we are) 1. GPS: 52°32'54.9"N 13°19'51.0"E ; 52.548581, 13.330842 2.

1 EURO DONATION FEE PER PERSON IS REQUIRED (on site, in cash), to pay back the Meetup subscription fees and support my Events. READ THE DESCRIPTION WITH THE INFO (IMPORTANT). We take a walk in Berlin to meet new people or people we already know 😁 It's a way to spend a few hours together on a public holiday afternoon. **How it works?** The concept is very simple: * We meet at Sonnenallee Station at 14,15 o'clock (we use the Whatsapp Chat to find each other: I will post there my exact location outside the station) * I wait for people for 10 minutes, till 14,25, then we start to walk direction Treptower Park, crossing the park 🌳🌳🌳 and going along the Spree river, to then go further * We go on along the Landwehrkanal, exploring Kreuzberg 🏠 * The total length of the walk is about 8kms * We land finally here to take coffee, a drink, or some food, and spend more time together ([https://maps.app.goo.gl/RsUCxwDKK6yVtiF48](https://maps.app.goo.gl/RsUCxwDKK6yVtiF48)) I consider that the event will last in overall around 4 hours (2 hours of walk 🚶🚶‍♀️ and 2 hours at the Cafe/Restaurant), but people are free to stay together longer, if they want 🙂 What I provide is leading the walk and the people at the Cafe, but I do not force anyone to stay shorter or longer. I do not provide a "personal support" for people who arrive after 14,25 (do not write to me expecting "private support"). You are responsible to check for the weather and decide if come or not.

**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.

**History** The history of [Blendon Woods Metro Park](https://www.metroparks.net/parks-and-trails/blendon-woods/) began long before its 1951 opening, rooted in a landscape of rugged ridges and deep ravines that made the land unsuitable for traditional farming. In 1945, a report proposing a metropolitan park system for Franklin County specifically highlighted these cliffs of Bedford Shale as some of the "wildest land in the vicinity". Following this recommendation, the recently formed park district purchased the first 229 acres in early 1949. Because the terrain was so uneven, developers had to cut a mile-and-a-half-long roadway through dense woods just to bring in heavy equipment. This initial preservation effort ensured that the mature second-growth hardwood forests remained largely untouched by the urban expansion spreading toward Westerville. Opening day arrived on Labor Day, September 3, 1951, marking Blendon Woods as the second park in the Columbus and Franklin County Metro Parks system. The final push to open was a frantic race; the State Highway Department only finished the primary gravel access road four days before the gates opened. Early staff members, consisting of just four full-time employees, had to hand-dig pit toilets and learn construction skills on the fly to build the first picnic shelters. Despite the dusty conditions and limited facilities, the park was an immediate success, drawing massive crowds from across Central Ohio. By the end of the 1950s, annual visitation had already climbed to over 190,000 people. As the surrounding suburbs grew in the 1960s, the park faced severe overcrowding that threatened its natural habitats. In response, Franklin County voters passed the first Metro Parks levy in 1960, providing the funds necessary for a decade of steady expansion. During this era, the park nearly doubled in size, growing from 264 acres to over 570 acres by 1968. Planners also addressed a critical water shortage by collaborating with the U.S. Soil and Conservation Service to build a lake in 1964. This body of water originally served as a temporary reservoir before its role shifted toward conservation and wildlife support. The 1970s marked a transition toward the specialized wildlife and educational focus for which the park is known today. In 1971, the Walden Waterfowl Refuge was established around the 11-acre Thoreau Lake, creating a sanctuary that remains restricted to provide a quiet habitat for migratory birds. A formal nature center was also developed during this period, expanding on the guided Sunday walks that had been a park staple since the early 1950s. The park’s famous "Monarch Mansion" also became a prominent fixture, starting a long tradition of raising and releasing thousands of monarch butterflies each September. These initiatives cemented the park’s reputation as a premier destination for birders and nature enthusiasts. In more recent decades, Blendon Woods has continued to modernize while maintaining its wilderness character. The 10-acre Natural Play Area was added in 2017, encouraging kids to explore the ravines and woods off-trail. This was followed by the opening of a $1.5 million inclusive playground in April 2025, designed to accommodate children of all physical abilities. The nature center also underwent major renovations to include immersive, three-dimensional exhibits and a new butterfly house. Today, the park encompasses 653 acres, preserving a unique geologic and biological corridor amidst the bustling Westerville and Northeast Columbus area. **Map of the Park** Here is a map of [Blendon Woods](https://www.metroparks.net/wp-content/uploads/2025/05/BLN_map_Inclusive-Playground-and-Butterfly-Trail_May-2025_1980px.png). **Summary** For this event, we will hike the Lake View, Hickory Ridge, Ripple Rock, Overlook, Brookside, and Sugarbush Trails. This sounds like a lot, but it will really be only a little over five miles. Blendon Woods has a few hills here and there, but it's not one of the more strenuous metro parks. **Where We'll Meet** We'll meet just in front of the Nature Center. This is about a mile into the park from the main entrance. You have to go past the Ranger Station and the Shadblow Reservable Area to get to it, so don't stop too early at the Ranger Station and get it confused with the Nature Center. **After the Hike** Afterward, we will head over to [Forbidden Root Restaurant & Brewery](https://forbiddenroot.com/restaurants/columbus-ohio/) at Easton for [drinks](https://forbiddenroot.com/restaurants/columbus-ohio/#dinner-menu) and [food](https://forbiddenroot.com/wp-content/uploads/Cbus-Food.pdf). We should be there by 5 if you can't make the hike and just want to join us for drinks. The brewery's actual address is [4080 Worth Ave, Columbus, OH 43219](https://www.google.com/maps/place/4080+Worth+Ave,+Columbus,+OH+43219/data=!4m2!3m1!1s0x88388a86d10b6619:0x4d42b470a5cf11d3?sa=X&ved=1t:242&ictx=111); however, I recommend pointing your GPS to the [Worth Garage](https://www.google.com/maps/place/Worth+Garage/@40.0542293,-82.9137962,17z/data=!3m1!4b1!4m6!3m5!1s0x88388b4df6082825:0x17582f0eccd9dda1!8m2!3d40.0542293!4d-82.9137962!16s%2Fg%2F11rzfvvv8b?entry=ttu&g_ep=EgoyMDI2MDQxNS4wIKXMDSoASAFQAw%3D%3D) across the street. Parking in this garage is free as long as you're not on the first floor, and it is literally right next to the brewery.

Join us this Thursday (5/14) at 6:30 pm at Rocky Fork Metro Park in Westerville as we walk about 2.5 miles of a fully paved trail. The Beech Woodland trail is a flat yet scenic trail with a variety of landscapes. Let’s take it in together!

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!
