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.

**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 event is organised by [RecWorks](https://recworks.co.uk/ "https://recworks.co.uk/") on behalf of the London Java Community.

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift.

The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.
