**„Květnový sraz, kde se řeší novinky i přístupnost s Claude Code!"** Jaro je v plném proudu a my se opět scházíme v pivovaru Lajka. Tentokrát na vás čekají čerstvé novinky ze světa frontendu a přednáška o tom, jak propojit Obsidian s Claude Code pro web accessibility. Vezměte dobrou náladu a přijďte! **Budeme se scházet postupně od 18:00 a od 18:30 máme na programu:** * 📰 Nowwwinky – Tomáš Kout * ♿ Obsidian + Claude Code = web accessibility **–** Petr Koláček * 🎲 Risk{f}uj! **Nowwwinky 📰 – Tomáš Kout** Co je nového ve světě frontendu? Tomáš pro vás jako vždy vybral to nejzajímavější, co se od posledního srazu událo. **Obsidian + Claude Code = web accessibility 👩🏽‍🦯 – Petr Koláček** Díky AI můžeme dnes poměrně lehce překonávat technologické bariéry a stavět aplikace, které bychom dříve sami nesvedli. Je to ale vždycky potřeba? Nejdeme často s kanónem na vrabce? Jak postavit nástroj, který nám pomůže s webovou přístupností pouze pomocí aplikací a služeb, které máme dávno k dispozici. *Petr je frontendový vývojář s více než 20letou praxí. Dlouhodobě se specializuje na CSS, webové UI, tvorbu design systémů a v posledních letech i na webovou přístupnost.* **„Risk{f}uj!" 🎲** Čeká nás další kolo oblíbené vědomostní soutěže na frontendová témata. Sestavte si tým a porovnejte svoje znalosti s ostatními soutěžícími. Těšíme se na vás v pivovaru! 🍻✨

**Liebe Gophers,** am 13.Mai geht es bei uns um eines der wichtigsten Patterns in verteilten Systemen: das **Transactional Saga Pattern**. Wer mit Microservices arbeitet, kennt das Problem – eine Bestellung aufgeben klingt einfach, aber dahinter stecken Payment Service, Inventory Service, Shipping Service... und jeder hat seine eigene Datenbank. Was passiert, wenn mittendrin etwas schiefläuft? Klassische ACID-Transaktionen funktionieren hier nicht. Sagas schon. Unser Speaker Mark Borukhov zeigt, wie das Saga Pattern funktioniert – mit echtem Go-Code, einem E-Commerce-Beispiel und Live-Demo. **Was euch erwartet:** * Warum verteilte Transaktionen ein echtes Problem sind * Saga Pattern: Konzept, Choreography vs. Orchestration * Implementierung in Go – Schritt für Schritt * Pitfalls, Lessons Learned & Q&A Das Event richtet sich an alle – von Go-Einsteigern bis zu erfahrenen Entwicklern. Auch wer Go nicht kennt, aber Microservices baut oder Patterns liebt, ist herzlich willkommen. **Der Vortrag wird auf Deutsch gehalten.** Wir treffen uns um 18 Uhr bei [lynqtech](https://www.lynq.tech/). Mit dem Vortrag starten wir um 18:30 Uhr. Danach wollen wir über Technologien und Erfahrungen plaudern, voneinander lernen, Kontakte knüpfen und einfach eine tolle Zeit miteinander verbringen. Wir freuen uns auf euch! 🚀 *Mark & Anna*

**The most enjoyable dance friending event on a Friday night 🌤️💃✨** This is an OPEN-AIR event! We are dancing outdoors on a soft athletic surface.

If you want to level up your dancing, be there at 7! Later, we flow into casual dancing, mixing European classics (Waltz, Polka) with modern Balfolk and chill Latin vibes (Forró). ✅ **No experience needed** → Come at 7 PM to learn the basics! 👣 ✅ **No partner needed** → We rotate!

Ordering drinks/food at the local restaurant is possible, but it breaks the flow, so we usually do it after we wrap up. 💃🔥

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!

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.

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.
