Coding Dojos

**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 talk is about the kind that protects your users. In this interactive session, we’ll break down password security into 3 key lessons exploring encoding, encryption, and hashing - and why the difference matters more than you think.. You’ll find out: * why some “secure” approaches fail instantly * how attackers use GPUs to crack passwords at scale * and why slowing things down is one of the best defences we have No prior security knowledge needed - just curiosity. Expect live polls, practical examples, and a few surprising insights into how passwords really get cracked. **[Alice Cheung](https://www.linkedin.com/in/alicespyglass/)** Alice is an engineering manager who moved from "fin" to tech. She helps organise Women Who Go as a way of paying it forward to a community that welcomed and supported her in her journey into the weird and wonderful world of engineering. She now works on creating better experiences and benefits in HR tech - and enjoys making complex topics like security and cryptography simple, practical, and (hopefully) a bit fun. **Translating Interview Speak: What Your Interviewer Really Wants to Know** Have you ever left an interview thinking that you nailed it and all you heard back was a short rejection? What happened? This session will help you to have better and less stressful job interviews. You’ll learn what’s behind the interview questions and what employers are really looking for. This information can help you to develop your best answers for your next job interview. This is based on information from the new book, Interview Speak: What Your Interviewer Really Wants To Know. We’ll cover how to: * Prepare for interviews * Answer common questions * Avoid mistakes **[Barbara Limmer](Swiped)**[ ](Swiped) Barbara is a professional Career Coach and Consultant who has personally coached thousands of professionals and executives from around the world.

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.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

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
