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.

**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.

This is a studio based long pose life drawing and painting session. We have a nude model for two hours in a single pose to give you time to complete a finished drawing or to paint the figure. You are welcome to draw or paint in oils or wet media. Our studio is purpose built and well equipped with easels, drawing boards, clips and so on. We sell materials at reasonable prices so if you forget anything we should be able to help you out. We have professional lighting for the models and full spectrum lights for the studio to give you a good experience. We break for 5 minutes for the model every 25 minutes This is not a tutored session but it is run by artist [Audrey Fattouche](https://www.instagram.com/audreyfattouche/), who will be happy to give guidance if requested and may suggest themes or ideas to consider during the evening.

Hi Architects, Welcome to our the Fourth AWS London Well-Architected User Group Meetup!!! 🥳🥳🥳 Dragon Hall Trust, 17 Stukeley Street, London WC2B 5LT The AWS London Well-Architected Meetup is the latest chapter in the most popular AWS Meetup group globally. At each meetup we cover off various pillars of AWS best-practice in detail including insights from industry leaders that specialise in the Well-Architected Framework. We’ll be updating throughout the month with more speakers and our speakers so far this month include: * **Breached at 3am: How AI is Redefining Security on AWS** \| Oluwasile Adesanya \[Solutions Architect\] from Cadware Limited An overview of how the Well‑Architected Framework is evolving with AI-driven tooling, focusing on how solutions like Kiro transform detection and automated remediation of threats, practical benefits for teams, and recommended implementation patterns and pitfalls to avoid. * **AI-Assisted AWS Well-Architected Assessments with AWS Security Agent** \| Mahendran Selvakumar \[Senior Cloud & DevSecOps Engineer\] from Tata Consultancy Services This talk explores how AWS's new Security Agent can transform the traditionally time-consuming AWS Well-Architected Framework Review (WAFR) process by leveraging AI to automate and accelerate security assessments. So come join us at 6.30pm for a 7.00pm start, including drinks, snacks and friendly networking after our talks :-)

**Everyone's talking about graphs now: What does Azure have to offer?** Microsoft Fabric now has a built-in graph database. So do you still need Neo4j? In this session we put Fabric Graph and Neo4j Aura head to head. Not as a marketing exercise, but as a practical decision guide. We’ll cover where Fabric Graph earns its place as a zero-friction, OneLake-native option for connected data, and where Neo4j Aura pulls ahead on query maturity, algorithm depth, and production readiness. We’ll run the same problem through both platforms live, so you can see the real differences rather than just read a feature table. You’ll leave with a clear decision framework: when to use what’s already in your Fabric capacity, when to bring in the specialist, and why the answer is sometimes both. **About the Speaker** Sandy is a Principal Innovation Consultant at Acora (a title all the cool kids aspire to) and Databricks Champion. He’s passionate about technology and finding the best tool for the job. Having recently worked on a project building out a knowledge graph, he’s got the experience with Neo4j to really show the differences between where it wins and where fabric wins.
