**The Talbot Room at the George Inn** The George provides the room free of charge (they are awesome), and we encourage you to purchase drinks (and food – the burgers are great!). As it’s a pub and not a picnic area, please don’t consume your own food and drink there. We usually meet in the Talbot room which is on the top floor on the left hand side of the pub as viewed from the courtyard. If lost please send a message here shortly before the meeting starts. **We are sorry to say that there is no step-free access to the Talbot room, and it is at the end of three flights of stairs.** **Format** We start at 7pm and run until 9pm. We hear approximately six readings of 10 minutes (\~2000 words), then discuss the piece for 10 minutes. Email your work to: london60transmitter@emailitin.com as an attachment (It must be an attachment). A link for access to googledocs will be given at the start of each session to enable people to read along, which in turn enables more considered feedback. Work submitted will be automatically deleted after 10 days. We decide on readers/pieces at the beginning of each session. **Safe and respectful space** The group is run by volunteers, and we don’t have the capacity to read submitted work in advance. If there is anything in your work that might distress or disturb some readers, for example concerning any kind of abuse, please give a trigger warning before you read. Be specific and concise. If it becomes apparent during a reading that a piece is inappropriate, the moderator will stop the reading. In discussing others’ work, please be mindful of how you express yourself and do not use discriminatory language, even if such language features in the piece.

A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **HOW TO BOOK**: **It's essential that you book onto sessions via our website, using the link below**; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals. [https://joinrabble.com/locations/london/](https://joinrabble.com/locations/london/) Use the code **FREEPLAY** to get your first game free! *** We play every: * Monday in Finsbury Park (19:00 - 20:00) * Tuesday in Shoreditch Park (19:00 - 20:00) * Wednesdays in Elephant & Castle (19:00-20:00) * Saturday in Southwark Park (10:30 - 11:30) * Saturday in Finsbury Park (11:00 - 12:00) * Sunday in Clapham Common (12:00 - 13:00) We hope to see you playing soon! PS. We have a group of dedicated regulars, so numbers are usually much higher than meetup might suggest.

June Edition ✨✨! We will be at the MongoDB London office! Django London Meetup is a monthly meeting to discuss Django, Python, the web, and related topics. The meetups are open to all with an interest in building websites with Django. (in-person only event, no streaming) **Talks:** **AI Agents Need Memory Too: Building Systems That Remember What Matters — Abigail Afi Gbadago** AI agents are only as good as what they can remember, but deciding what to store, where to persist it, and how to retrieve it at the right moment is harder than it sounds. This talk walks through a practical framework for architecting memory systems for agentic applications, covering memory types, storage patterns, retrieval strategies using vector search, and managing the full memory lifecycle in production. Afi is a Senior Software Engineer and Developer Advocate (MongoDB). She serves as Vice President of the Django Software Foundation, a Fellow of the Python Software Foundation, and is a Microsoft MVP for Python and Web. Afi is passionate about building great software and stronger tech communities. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Replay Failed Python Runs: Reverse Debugging When Logs Aren’t Enough** **\- Nathan Matthews** Reproducing Python failures from a traceback alone is often impossible once the request is gone or the environment has changed. This talk introduces Retrace, an open-source reverse debugger that lets you record, replay, and step backwards through a failing run, giving both developers and AI agents concrete evidence for debugging. Nathan Matthews is Co-founder and CTO of Retrace Software. He has spent his career building complex Python and distributed systems across fintech, developer tools, and data platforms, including roles at 10x Future Technologies, Digital Asset, Elsevier, and Droit. At Retrace, Nathan leads the technical work behind deterministic replay and reverse debugging for CPython. **Want to share your Django or Python knowledge?** We’d love to feature your talk!

🎉 Come along to the London Scala Talks for a deep dive into functional architecture! 🎉 In this event you'll hear from David Lebl and Przemysław Pokrywka. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan and vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event will not have a live stream** We hope to see you there in person. **🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules** Focus on software architecture is not always associated with pragmatism in common perception. Terms such as architecture astronautics and the ivory tower stereotype highlight the perceived disconnect between many architects and the realities of day-to-day code maintenance. Too often, architectural patterns are applied with insufficient understanding, leading to cargo-cult adoption and increased waste in the software development process. When applied in the right context, however, certain architectural approaches can be powerful enablers. In this talk, I would like to share the story of a serverless application in which elements of the Ports and Adapters architecture made a tangible, positive difference. ⭐ Przemysław Pokrywka ⭐ Husband, dad, grandad, software engineer. Functional Scala enthusiast with imperative OOP Java background. Fan of the command line. **🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive** A visual journey from spaghetti to sanity. This talk traces how cognitive load accumulates in unconstrained codebases, how domain-driven design and bounded contexts restore order, and how hexagonal architecture provides a practical, forgiving structure for real-world systems — all laid out on a single zoomable canvas where every example links back to the bigger picture. ⭐ David Lebl ⭐ David is a software developer with a CS background and 5 years of Scala and FP experience. He leads a small team, occasionally survives his own accidental complexity, and is here to share what he learned the hard way. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

# 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**.

For decades, application security has been built around a simple assumption: humans are the primary producers of software. We train developers, review their pull requests, model threats in design meetings, and build controls around human decision-making. That assumption is rapidly breaking down. As AI coding assistants evolve into autonomous software agents, organizations will gain access to an effectively unlimited engineering workforce capable of producing software at a speed no human team can match. The pressure to adopt these systems will be driven not by curiosity, but by competition. Companies that successfully harness agentic development will ship faster, iterate faster, and potentially outpace those that do not. This shift forces a fundamental rethinking of application security. The future of AppSec is not securing developers—it is governing an agentic workforce. Threat modeling, code review, security testing, and change management will not disappear, but they will need to operate at machine speed and increasingly be performed by systems rather than people. In this talk, Ken Johnson, CTO of DryRun Security, explores what the next decade of application security may look like, the assumptions that will no longer hold, and why security professionals must understand these systems deeply if they hope to influence the future rather than react to it.
