**Join us on *Discord* to keep updated!** **[(Click me! Online Offline Discord)](https://discord.gg/uuwybw93kj)** Meetup with a group for a nice stroll in Battersea park! Bring a coffee.. or grab one in the parks café after! This event is weekly! Get out and about in Battersea park with new people! This isn't a strict walk - however it should be a scenic, fun and enjoyable walk for people of all ages, sizes & abilities! If you're looking for something more energetic have a look at some of our other group exercise activities!

We are back! This is going to be a monthly IN PERSON meet up in London. A very big thank you goes to Accurx who is hosting us in their amazing Shoreditch offices. This will include access to facilities including coffee! 😻☕️ **Want to know more? 👇** As with all CoffeeOps, this is an interactive, chatty, build your own adventure type of meet-up. Instead of booking in experts to *learn* *from*, we gather a group of practitioners to ***learn*** ***with***. We have been running for over 4 years now and often get feedback that this is the most useful meetup people join! The event is approximately 90 minutes and always starts by brainstorming topics to discuss. The group then votes on the most relevant/interesting to them and we then cycle through the topics trying to discuss each deeply, but in a time bound slot. To get an idea of topics, you can check out our remote board [here](https://easyretro.io/publicboard/h404NF84Uje4tCcxpJdHr4Ycs9B3/a4a35d2b-181b-409b-832e-a729be1af79c). The general gist is anything is fair game, though we tend to revolve around software delivery and definitely lean towards the more Ops-y or DevOps-y side of things.

Please join us for our weekly run and social - a great (free!) way to meet new people! We meet at 7pm outside The Horatia ( https://maps.app.goo.gl/p1QnyurFQh3gywov6) and head for the run together from there. You can leave a small bag or extra layer at the pub at your own risk. The winter route is around Highbury Fields and in the summer we do a loop to Clissold Park, both ending at the starting point- the Horatia pub. We run 5km at an easy pace (about 6-7 mins per km), with some people going faster and some slower. After the run, we will head to the Horatia pub for some drinks (alcoholic and soft are fine- no judgment!).

Join us on June 11th from **6:00pm** for a Data Streaming meetup hosted by **Moniepoint!** **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name. For security purpose** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:15pm: Tom Scott, CEO, Streambased * 7:15pm - 8:00pm: *Abraham Imohiosen,* Engineering Manager * 8:00pm - 8:30pm: Q&A Networking. 💡**Speaker One:** Tom Scott, CEO, Streambased **Title of Talk:** Infinite Kafka? Rethinking Retention with Iceberg **Abstract:** Apache Kafka is designed for high-throughput, low-latency event streaming, not cost-efficient long-term storage. Yet we constantly see cases like event sourcing, audit/compliance, and large-scale reprocessing forcing that pattern onto it. As retention increases, costs grow linearly to support edge cases, one-time runs, and “checkbox” use cases. Can Iceberg help here? In this talk, Tom explores a hybrid architecture that separates hot and cold data while preserving Kafka’s log semantics. Using a combination of Kafka and Apache Iceberg, he demonstrates how to extend Kafka into low-cost object storage, enabling effectively unlimited retention without sacrificing performance or access patterns. The result is a unified log that supports both real-time processing and long-term replay, removing the traditional trade-off between cost and capability in Kafka-based systems. **Bio:** Long-time enthusiast of Kafka and all things data integration, Tom has more than 15 years of experience in innovative and efficient ways to store, query, and move data. Tom is currently CEO at Streambased, a company focused on unifying operational and analytical data estates into a single, consistent, and efficient data layer. 💡**Speaker Two:** Abraham Imohiosen, Engineering Manager, Fraud Prevention Tools. **Title of Talk:** From CDC to Decision: Kafka as the Fraud Detection Pipeline's Connective Tissue **Abstract:** Fraud detection isn't one system — it's a system of moving parts (databases, feature stores, rule engines, ML models, case management tools) that all need to agree on what just happened, in milliseconds. Kafka sits in the middle of it, and treating it as "just the message bus" leaves a lot of value on the table. In this talk, I'll walk through three jobs Kafka does inside Moniepoint's fraud detection pipeline: moving events between services, powering real-time aggregations and windowed features, and acting as a CDC source that turns database changes into the canonical stream feeding a final aggregate store, as well as routing evaluated events into the case management system for final decisioning. **Bio:** *Abraham Imohiosen is an Engineering Manager at Moniepoint, where he leads the Fraud Prevention team in building case management systems and machine-learning detection models that protect millions of customers and billions in transaction volume. He has over 10 years of experience across fintech and cloud-based architectures, having previously led the delivery of Monieworld Transfers and a savings product. Abraham holds an M.Sc. in Robotic Systems Engineering from RWTH Aachen University.* \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

# Learn how to use open-source harnesses like OpenCode & Pi w/ your own LLM and with it, build a real-world application **Registration to this event is only valid through the Luma platform:** [https://luma.com/11txn8gq](https://luma.com/11txn8gq?utm_source=meetup-dot-com) ​Hello code campers! ​Since everyone is talking about using harnesses such as **Anthropic Claude** or **OpenAI Codex**, meaning, everyone is probably tired of hearing about them, we've decided to go in a different direction and explore other, lesser known things such as, [OpenCode](https://opencode.ai/?utm_source=luma) and [Pi DOT Dev](https://pi.dev/?utm_source=luma). Come and join us and learn how to work with a wide range of open-source large language models (**LLMs**) such as **DeepSeek V4**, **Gemma**, **Kimi K2**, and **GLM** across various local-first environments. This comprehensive workshop is designed to teach you what is a code harness, how many types of them there are out there (you might be familiar with **Claude Code** or **Codex** or **CoPilot** but there are others and since the big-tech companies are moving to token-based usage, why not run your own solution locally). Also, we'll explore how to go about having effective agentic coding workflows while benchmarking model performance and hardware requirements. ​We will go through the setup process, focusing on how to install the desired LLM runner like Ollama or LMstudio locally. ​This will be our **7th** event in our series of **local-first, open-source** AI events; therefore, we will try to focus on building a setup that doesn't depend on Big Tech but on smaller open-source tech instead. ​This workshop is open to all levels, from beginners to experts. ​Bring your laptop (make sure it's fully charged as local LLMs tend to be power-hungry), and don't forget to bring your coding gear (hoodie). ​This workshop will be most likely accompanied by a guest speaker (TBD). *** ## ​Prerequisite ​Prerequisite: a local Ollama, LMStudio installation or equivalent (but if you don't have any of that, don't worry, come a bit early and we will help you). ​If you want to take a quick look at the slides from the previous events fell free to do so: [​https://andysign.github.io/ai-london-01/](%E2%80%8Bhttps://andysign.github.io/ai-london-01/) (Ollama); [​https://andysign.github.io/ai-london-02/](%E2%80%8Bhttps://andysign.github.io/ai-london-02/) (LangFlow, not really related but still) [​https://andysign.github.io/ai-london-03/](%E2%80%8Bhttps://andysign.github.io/ai-london-03/) (private RAG w/ Anything LLM) [​https://andysign.github.io/ai-london-04/](%E2%80%8Bhttps://andysign.github.io/ai-london-04/) (AI-native browsers) [​https://andysign.github.io/ai-london-05/](%E2%80%8Bhttps://andysign.github.io/ai-london-05/) (OpenClaw basics) [​https://andysign.github.io/ai-london-06/](%E2%80%8Bhttps://andysign.github.io/ai-london-06/) (OpenClaw advanced) *** ## ​Agenda for the evening (Subject to change) ​**18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. ​**18:30 - 18:45 Introductions** Intro and a bit of audience engagement. ​**18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). ​**20:30 - 20:45 Guest Speaker** ​**20:30 - 21:00 Networking** ​**21:00 - Closing remarks and follow-up** ​ **END:** Carry on the fun at a nearby pub around the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**. [Encode Club ](http://encode.club)has spent over five years fostering a global community of developers, researchers, and founders in Web3, AI, and emerging technologies. The [Encode Hub](http://hub.encode.club) brings everything together under one roof, providing a dedicated environment for collaboration and innovation through meetups, co-working, and in-person events.

We are excited to host our coding dojo with Spektrix! We'll kick off with an introduction to TDD, its core principles, and following disciplined emergent design. Through hands-on pairing and mob programming, you'll experience how writing tests first doesn't just catch bugs, it shapes cleaner, more intentional code from the ground up. **What about AI tooling?** We encourage the use of AI tooling! We will briefly walk through how such tooling can act as multiplier, not to shortcut the discipline of TDD. **Don't have AI tooling?** No problem. TDD is a discipline that stands on its own, with or without AI. But if it's something you'd like to try, we can pair you with somebody who has the tools set up. Join us for an evening of coding, food and drinks. Come and code along, share ideas, discuss best practices with Test Driven Development and learn from our expert Crafters and your peers in the London Software Craftsmanship community. **What’s the format?** After a short intro, we’ll get into groups/pairs or work solo, whatever people feel most comfortable with, and start building. You choose how you want to work and what language you want to code in. This session is about collaborating with others, becoming a better developer and building your network, in a fun, relaxed environment. We'll be sharing ideas, discussing best practices and using this as an opportunity to learn from our fellow coders. All levels of experience very welcome, if you want to brush up on your Test Driven Development skills or are a complete novice, do come along. All welcome! All you need to do is bring a laptop if you’d like to code along - please have your preferred language and editor setup. **Food and Drinks** Pizza and drinks will be provided upon arrival

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
