**Please register on [Eventbrite](https://www.eventbrite.co.uk/e/ljc-meet-up-at-redis-tickets-1989301512374) join this event.** **About this event** The LJC is delighted to be partnering with our sponsor **Redis** for an exciting meetup! This will be a wonderful opportunity to learn, network and enjoy great food together. Huge thanks to our friends at **Redis** for sponsoring this event and supporting our Community. **Agenda:** **5:30pm:** Doors open **6pm:** LJC and Redis intros **6:10pm:** Samuel Agbede: Designing Production-Ready Multi-Agent Systems with Spring AI **7pm:** Break & food **7:30pm:** Leif Åstrand: UI with Redis and Vaadin using 100% Java **8:15pm:** Networking **9pm:** Event finish **Speaker One:** Samuel Agbede, **Title:** Designing Production-Ready Multi-Agent Systems with Spring AI **Synopsis:** Exploring how Redis can go beyond traditional caching to support semantic caching, intelligent routing, and short-lived application memory in AI-driven Java systems. **Speaker Bio:** Software Engineer and Developer Advocate at Redis focused on AI agents and memory systems. Samuel explores how context, retrieval and state shape intelligent behaviour in real-world applications. **Speaker Two:** Leif Åstrand **Title:** UI with Redis and Vaadin using 100% Java **Synopsis:** Full-stack development can be intimidating, especially when going beyond the typical CRUD. A reactive application with real-time updates requires knowing things like WebSockets on top of the regular frontend stuff. But what if you could build a full-featured full-stack web app using only straightforward Java? No JavaScript, no HTML, no CSS. Just Java. Join this live coding session to discover how to develop a reactive web app using Spring Boot, Redis and Vaadin. Starting from scratch, we'll cover everything: real-time updates, external services, and a good-looking UI. All in Java. **Speaker Bio:** Leif has been working with full-stack web application development in various ways for the past 20 years. Building applications, building frameworks for building applications, and in the last few years mainly working to understand what it takes to build applications. Works at Vaadin in areas related to product management, research, architecture and product development.

We are excited to announce our May Community Showcase. This event is an opportunity for individuals at all skill levels to come together and share their experiences with Rust. Whether you’re working on a personal project, contributing to an open-source initiative, or teaching a concept related to Rust, we invite you to present your work and insights. Take this opportunity to build your confidence and share what you are doing. Speakers === **Sang Young Noh** **Talk title:** FerrumMD: Building a Molecular Dynamics Engine in Rust **Abstract:** FerrumMD is a molecular dynamics engine written in Rust, built to explore high-performance scientific computing from first principles. The project implements core simulation components, including Lennard-Jones interactions, periodic boundary conditions, Verlet integration, velocity rescaling, and electrostatics via Particle Mesh Ewald. It aims to bridge computational chemistry, systems programming, and extensible design for future free-energy workflows. === **JC Campagne** **Talk Title:** DAGraph: Local reactive graph-based data analytics in Rust. **Abstract:** DAGraph is a reactive node-based canvas app for local data analytics — every cell is a node in a reactive DAG, from basic arithmetic to OLAP-style SQL. Built in Rust, it runs natively or fully in-browser via WASM, with no server and no data leaving your machine. === **Darek Luksza** **Talk Title:** Building a streaming technical-analysis crate in Rust **Abstract:** Darek will share lessons from building quantedge-ta, an open-source Rust crate for technical analysis indicators designed for streaming market data rather than batch-only calculation. The talk will cover practical problems around warmup periods, convergence, forming versus closed bars, and stateful updates, plus where Rust helped and where the ergonomics became tricky. === **Ben Knightsberg** **Talk Title:** AI and Encryption: Hmm or Mmm? **Abstract:** A wacky deep dive into modern encryption, focusing on homomorphic techniques and their practical implications through Rust. Drawing on recent work, we'll explore how secure computation can unlock value without exposing data. We'll also figure out how to successfully engage partners to invest in encryption initiatives, translating complex cryptography into tangible business outcomes and strategic advantage across multiple sectors globally.

Join us as we get together to see Paul Rudd in the latest comedy-drama-musical from John Carney, POWER BALLAD! The film follows a washed-up wedding singer, a fading boy band singer and a stolen hit song. Here’s a description, trailer and plan for this event: DESCRIPTION: Rick, a washed-up wedding singer, and Danny, a fading boy band star, bond over music and a late-night jam session. When Danny turns Rick's song into a hit, Rick sets out to reclaim the recognition he believes he deserves. Power Ballad is written/directed by John Carney, the master of the modern musical and creative mind behind Once, Begin Again and Sing Street! It stars Paul Rudd, Nick Jonas, Peter McDonald, Marcella Plunkett, Havana Rose Liu and Jack Reynor. BUZZ & ACCLAIM: The film premiered to rave reviews at this year’s Dublin International Film Festival where critics call it “a sure-fired crowd-pleaser” that “just might be the feel-good hit of the year!” Others say, “Paul Rudd delivers a career-best performance in this charmer” that’s both “hilarious and deeply moving!” SUMMER OF ICE CREAM, VOL 2: SHAKE NO. 8!

We'll head to nearby Shake No. 8 immediately following the show! Should be a fun one, Dan

This is the 50th Anniversary of the Judgment of Paris. Significantly, in 1976, California wines unexpectedly outperformed French wines in a blind tasting with nine French judges, challenging the perception that only French wines were of the highest quality. This event helped elevate the status of California wines on the global stage and is considered a pivotal moment in wine history. House Wine, in Worthington, modestly, recreates that moment in history with a tasting both American and French wines in a fun, casual atmosphere. Come at 6:45, pay your fee at the register and join your friends for this "Judgey" tasting. https://www.wineenthusiast.com/culture/wine/the-judgment-of-paris-turns-40/ Arrive when you can and we'll have a table for gathering. Feel free to bring your own food as it is welcomed at this local gem or order from the newly opened Worthington Inn, or local favorites such as Dewey's, Everest, Jet, Worthington Tavern and The Whitney. Each person pays their tasting fee, typically $15, and gets their wine glass, then approximately five pours of the wines being served. **Parking is tough**. Try the second lot behind House Wine accessed by the land by the back parking lot or the municipal lot one block north of House Wine. **Waiver and Liability and Attendance Policy.** Participation by you and your guests means you agree to the Waiver of Liability and Attendance Policies on our Group Page. People who have two more or Attendance policy violations are subject to removal from the group.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
