Linux

Pollen's out! Come hide from it indoors, and meet like-minded people with a common interest in Linux in a lively pub at the at the May Linux London Meetup "Oh, look, it's hayfever season" edition. Whether you are a complete neophyte or Linux warrior with decades of experience, come join the chat about distros, networks, open-source software, personal projects, ... or nothing related whatever. The venue is the Hand & Racquet in Wimbledon (25-27 Wimbledon Hill Rd, SW19 7NE). [https://www.greeneking.co.uk/pubs/greater-london/hand-and-racquet](https://www.greeneking.co.uk/pubs/greater-london/hand-and-racquet) Chris and Gulraj will be sharing hosting duties with at least one of us present at each meetup. Whilst we realise that this venue is not as convenient for some people as our central London former haunts, the pub is only 2 minutes walk from the station, and Wimbledon is exceptionally well connected (only 17 minutes out of London Waterloo mainline, lies on the Sutton branch of the Thameslink, and is a terminus of both the District Line and the Croydon Tramlink). The pub is on the flat, at street level, including the toilets, although the space reserved for us (presently, at least) is a raised mezzanine area up a small number of steps at the back of the pub. We aim to be inclusive, so if this presents an issue, we'll work with the pub to adjust the arrangements in the future. Sign-ups are open. Please come join us. Directions from the station: Exit the station through the main concourse (near the District Line platforms), turn right along the main road, passing the taxi rank on Orinoco Lane. Cross Alexandra Road at the traffic lights, pass the gym on the corner, then continue past the chemist to reach the pub.

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.

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
