The world is in crisis and many people think we've gone past the tipping point and the planet is doomed. However, there are those who have hope and faith in science that some can survive the polycrisis and get to live in a sustainable society and planet. But there's a problem... **There's no clear vision of what a sustainable society and planet should be**, and without that destination, how can we set out on the journey to get there? Please join like-minded people to discuss this. We'll agree an agenda at the start of the meeting. Bring an open mind, suggestions and perhaps a pad of paper. **Here are some topics to be covered.** Please use the comments/chat to suggest other areas for consideration *Depending on the mood of attendees, the frequency of further meetups can be agreed.* **WHAT DO WE WANT A SUSTAINABLE SOCIETY AND PLANET TO LOOK AND FEEL LIKE?** · A planet with clean atmosphere, oceans and soil with systems in place to keep them that way · The abolition of poverty and hunger · Equality of opportunity for all to achieve a peaceful and contented life without fear of physical or other violence · Access to healthcare, hygiene and sanitation for all · Access to quality education for all · A more responsible system of financial structures which embraces the best of co-operative production, capitalism and other systems · A safe justice system for all · Societies which respect for the diversity of opinion, ethnicity, sexuality, religion · Respect for the natural resources and fragility of Planet Earth and their finite capacity · Societies where the more fortunate, stronger and healthier help those less strong, less fortunate or less healthy. · Peaceful co-existence between the varying communities of the planet **What Freedoms ?** · Freedom to travel anywhere · Freedom to worship (should there be limitation such as worship should not be based on destroying the existing system…??) · Freedom from violence · Freedom from hate · Freedom from poverty (how define?) · Freedom of speech · Freedom from anxiety about the future · Freedom from concentration of power · Freedom to preserve culture and arts · Freedom to make decisions about one’s body · Freedom to seek representation and to represent others · Freedom to be different · Freedom to be heard

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?

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
