Dies ist ein informelles Treffen für Lernende, die ihre ersten Schritte in der Programmierung machen oder ihre Grundkenntnisse vertiefen möchten. *** This is an informal meetup, for learners that want to do their first steps in programming or want to consolidate their skills. We spend one hour and a half working on tutorials, exercises or projects. If you need help to get started, we will help you finding a good way for learning. You should be prepared to spend your time "doing things": just hanging around and listening might get boring, if all other people are learning on their side. There are experienced people are around and you can ask questions as soon as their arise or bring with you questions you have had during the week. During the last half an hour, we do a (simple) exercise together. We speak German, English, and a few other languages.

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. **Agenda** \- 4:30pm: Doors open\, Snacks\, and Networking \- 5:00pm: Welcome\, Community update \- 5:10pm\~5:40pm: Tech talk: GitHub Copilot overview \- 5:40pm\~6:40pm: Tech talk: GitHub Copilot in Practice \- 6:40pm\~7:30pm: Open discussion and closing **Tech talk: Mastering GitHub Copilot CLI** **Speaker:** Aymen Furter - Cloud & AI Solution Engineer, Microsoft **Abstract:** Learn to harness the power of agentic development by transitioning to autonomous, multi-step terminal workflows. This session focuses on mastering plan-based execution, repository-aware context, and integrating external data via the Model Context Protocol. **Tech talk: GitStop Using GitHub Copilot Like a Toy** **Speaker:** Emanuele Bartolesi - GitHub Tech Lead, Xebia **Abstract:** GitHub Copilot is easy to love in a demo. Real projects are different. Production codebases come with legacy code, missing context, inconsistent patterns, unclear requirements, and delivery pressure. That is where GitHub Copilot either becomes a real advantage or just an expensive toy. This talk focuses on practical ways to use Copilot in real development workflows, going beyond autocomplete. Agent mode, skills, Copilot CLI, and better prompting can make a real difference when working in messy repositories and under real deadlines. Designed for developers and tech leads who want more than flashy demos, this session shares concrete tactics to get better output, reduce noise, and make Copilot genuinely useful in day-to-day software delivery.

**What is SOLA?** [SOLA ](https://asvz.ch/event/412-sola-stafette)is a relay run around Zurich city. A 14x runners team covers a total distance of 114.77 km and an altitude difference of 2,640 m in the greater Zurich area. The 14 sections are between 3.69 - 14.11 km long suitable for all type of runners. **How can I participate with the hashers?** Register using this form: [SOLA 2026 Hash Rego Form](https://forms.gle/u32k4FHWTDaPpKzF8) Teams and allocated legs are available [here](https://docs.google.com/spreadsheets/d/1Q6skotPebRNoYWr4WR0YRG2A2BcU10DkdV4krR8NE0w/edit?usp=sharing). This year we have only two SOLA hash teams. **How much does it cost?** For those allocated a place please pay your registration fee of ***CHF*** ***40*** into the regular ZH3 account referencing SOLA 2026 and your Hash name at: **Migros Bank AG, 8010 Zürich** BIC: **MIGRCHZZXXX** IBAN: **CH74 0840 1000 0519 9117 9** Account holder: **Zürich Hash House Harriers** Address: **Gloriastrasse 88, 8044 Zürich** Reference: **SOLA 2026 + Hash Name** **What else should I know?** TBC if SOLA will have dedicated haberdashery. A final party/grill will be organized at the finish line at Irchel park. If you would like to place yourself on the standby list please contact *Premature Cocksucker* (and maybe other hashers). All Zürich Hashers are welcome to cheer on our Hash teams along the route and also to circle starting at 18:00 at Irchel University (follow the pin location). Hash cash will not be collected from regular Zürich Hashers on the day. Regular SOLA rego is CHF 40. As last year SOLA allows all genders to run any of the stretches. The race starts with a leg 1 at 7:30 (all registered teams are slow teams) in the misty Hönggerberg woods. Then runners 2 to 7 head out into Engstringen, up and along the Uetliberg and back into town, finishing at the beautiful University Irchel. The afternoon runners 8-12 start at 12:30 . The trail heads through Forch to Egg and comes back to Witikon. Two short runs from there to the finish at Irchel complete the race. We meet at tents across the lake from the finish. Handover is done by a handshake to the next runners so **it's important to turn up early**. Runners 1, 8 and 13 start sharp at 7:30, 12:30 and 16:45 respectively.

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!
