Hi folks! Welcome to our July Cloud Native London meetup! Join us to hear from our two speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube or LinkedIn! 6:00 Pizza and drinks 6:30 Welcome 6:45 Hossein Kakavand, Luther Systems (Talk TBC) 7:15 Putting Open GitOps to the test (Steve Fenton, Octopus Deploy) 7:45 Wrap up See you there! Cheryl (@oicheryl) **Putting Open GitOps to the test (Steve Fenton, Octopus Deploy)** The Open GitOps principles sound plausible, but the world is full of surprising realities. Join Steve Fenton and explore the GitOps research to see whether GitOps delivers on its promises, based on an analysis of over 600 perspectives from roles like DevOps engineers, developers, platform engineers, and cloud infrastructure engineers. *Steve Fenton researches the socio-technical systems behind software delivery; how organizations, people, and technology actually work together (or don’t). At Octopus Deploy, he explores GitOps, Platform Engineering, Continuous Delivery, and compliance through a lens shaped by punk history, psychology, and the kind of genre fiction that asks uncomfortable questions about systems and society.* *He’s an eight-time Microsoft MVP (DevOps), a DORA Community Guide, a CD Foundation Governing Board member, and a contributor to the CNCF Platform Engineering Community Group. He’s written books on TypeScript, Octopus Deploy, and Web Operations Monitoring, and occasionally writes horror fiction.* *https://www.linkedin.com/in/stevefenton/* *https://mastodon.social/@stevefenton* *https://bsky.app/profile/stevefenton.co.uk* *Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.*

Taking inspiration from the exhibition at the V&A Photography Centre we will embark on a street and environmental photography workshop. Photographers currently on display are Elliott Erwitt, Robert Mapplethorpe, Dorothea Lange, Edward Weston and the controversial Sally Mann amongst other giants. Come and learn a little history of the photographers and be surprised at who shot some well known music album covers! Afterwards we will head out and shoot street and environmental photography around South Kensington. EQUIPMENT * Any camera * Any lens * An open mind and fun attitude! TRANSPORT As usual check the TFL website for any disruptions that may delay your journey on the day.

**Please register on [Eventbrite](https://www.eventbrite.com/e/ljc-meetup-at-neo4j-smarter-search-with-spring-ai-and-neo4j-tickets-1991379537804) to join this event.** **About this event** We're excited to invite you to our next Meetup, co-hosted with neo4j! Join the London Java Community for an evening of technical talks, networking, and knowledge sharing hosted by Neo4j. This month’s meetup explores two of the hottest areas in modern software development: integrating Generative AI into Java applications and deploying Machine Learning models within Java ecosystems. Whether you’re a Java developer, architect, data engineer, or simply curious about the latest innovations shaping our industry, this session will provide practical insights and real-world examples from experienced practitioners. **SPEAKER 1** **Akmal Chaudhri**, Neo4j Title: Smarter Search with Spring AI and Neo4j Abstract: In this session, we'll walk through a Spring Boot app that integrates Spring AI with Spring Data Neo4j to build intelligent search over real Goodreads book data. We'll cover how to set up a Neo4j vector store, generate embeddings via OpenAI and expose results through a REST API. We'll also explore how graph search and vector search work together and what it takes to configure and connect these pieces in a Spring application. If you've been wondering how to bring GenAI capabilities into your existing Spring stack, this talk offers a practical, code-first look at how it all fits together. Bio: Akmal is a technical leader and evangelist with extensive experience across databases, AI and developer enablement. Specialised in technical writing, education and community strategy, he has a proven ability to translate complex technology into clear, engaging narratives that inspire learning and adoption. He is a regular international speaker, published author and contributor to thought leadership in data systems, AI and developer education. **SPEAKER 2** **Matt Scott**, CTO, Nimbus Pay & **Alex Callinan**, Data Scientist, Nimbus Pay Title: Integrating Machine Learning models with Java Abstract: This presentation walks Java developers through the full journey of integrating machine learning into their applications. It then weighs up the pros and cons of two practical deployment paths. Matt Scott bio: Matt is a cloud-native architect and fintech leader with over twenty years building secure, scalable payment platforms, including containerized JVM-based systems. As CTO of NimbusPay Technologies, he designs cloud-agnostic card issuing solutions, with deep expertise in Java architecture, distributed systems, and DevSecOps. Alex Callinan bio: Alex is a Data Scientist at NimbusPay Technologies, where he builds and ships machine learning models into production. He's passionate about bridging the gap between trained models and the real-world applications that put them to work. This event is organised by RecWorks on behalf of the London Java Community. The London Java Community is sponsored by Hazelcast, Neo4j, Redis, and Discover

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
