OCaml Programming

Hi guys! welcome! hope you’re all well. Join us for our first walk & talk event in camden. We’ll be meeting on the 14th @10:00AM at King’s Cross Station (exact meetup location will be disclosed the day before on our whatsapp groupchat). It’ll be a short and relaxed walk around king’s cross. We’ll be walking through granary square, exploring coal drops yard and then walking to gasholders park before making our way back to king’s cross and to a little hidden park! The walk will probably take about 30mins depending on whether we stop for coffee/snacks or let the kiddos explore for a little bit. The route is family and buggy friendly with lots of opportunities for drink/snack stops and there’s access to toilets and baby change facilities. Join our WhatsApp community to stay in the loop with all of our events and updates: https://chat.whatsapp.com/CWefJ5Kage1L0W2Sco6eOu Looking forward to seeing you there!

MCP is changing how developers build with AI, but we're just scratching the surface. Join us for an evening of talks that go beyond retrieval to explore what's actually possible when you give agents real tools, real constraints and real APIs. **Agenda** ​6:00 PM - Doors open, registration and networking ​6:10 PM - Welcome (Upsun & Cloudflare) ​6:20 PM - MCP: Context is Everything! - Carly Richmond, Elastic ​6:45 PM - Sandboxes: how to limit agents so we can use them more - Patrick Dawkins, Upsun ​7:00 PM - Break (Food & Drinks) ​7:30 PM - Cooking with MCP in VS Code - Liam Hampton, Microsoft ​7:55 PM - Efficient tools with MCP code mode - Confidence Okoghenun, Cloudflare ​8:15 PM - Open networking and drinks ​9:00 PM - Close 🗣️ ​**Talks** ​**MCP: Context is Everything! - Carly Richmond (Developer Advocate Lead, Elastic)** ​MCP is a powerful tool for giving LLMs capabilities to not just retrieve information, but to automate key actions based on relevant data. Let’s see how it can be used for retrieving relevant context and other activities such as observability. ​**Efficient tools with MCP code mode - Confidence Okoghenun (Senior Developer Advocate, Cloudflare)** ​Traditional MCP approaches choke on context windows: Cloudflare's 2,500+ endpoint API would require 1.17 million tokens. Code Mode flips the script by having LLMs write code against typed APIs instead of making direct tool calls, achieving 99.9% token reduction. Come learn how code mode works and how to optimize your MCP tools with it. ​**Sandboxes: how to limit agents so we can use them more - Patrick Dawkins (Principal Engineer, Upsun)** ​We want our agents to run longer and use more tools, but we're hampered by constant prompts for approval. Sandboxes are the practical middle ground: isolate the agent so you can stop watching every command and let it work. This talk covers what "sandbox" means, who provides them today and the Linux primitives that let you build one yourself. ​**Cooking with MCP in VS Code - Liam Hampton (Senior Cloud Advocate, Microsoft)** ​In this session Liam will show you how VS Code is fully supporting the MCP spec, from MCP Apps to sandboxing and elicitations. 📅 **Date and Time:** Thursday, May 14, from 6:00-9:00 PM 📍 **Location:** Cloudflare Address: 6th Floor, County Hall/The, Riverside Building, Belvedere Rd, London SE1 7PB, UK 👉 You can also register here: https://luma.com/eb8j6lhu ⚠️ Please make sure you provided your full name (no nicknames or abbreviations will be allowed) and to bring your ID card as it will be mandatory to show it upon check-in to security. Entry will be first come, first served. We recommend arriving early to make sure you get in. **⚡️ Interested in giving a talk? ⚡️** Have you ever considered presenting on your Elastic use case? We welcome 5-10 minute lightning talks, 45-minute deep dives, and everything in between.

Shaping our future with AI. Creating opportunity through AI fluency, connection and community. No jargon. No hype. No confusing terminology. NOTE: This event will be focussed on the changing shape of software development. Everyone is welcome to attend but the content will be somewhat technical. **Join us for our next in-person meetup in London on Thursday May 14th.** Our theme for this meetup is **Reimagining Software Development with AI.** We're going to take a step back and think about the role we, the humans, play in the software development process now that coding agents have arrived. This event provides a small glimpse of the future, from the innovators who are challenging everything and rebuilding the process of software development from the ground up, with humans at the centre! **Where and When?** * Thursday, May 14th * Doors open at 18:00 * Talks start at 19:00 * AutogenAI, 123 Pentonville Rd, London N1 9LG **Talk 1: The Validation Gap: We Need A Better Way To Review AI Generated Code** (Robert Werner, Co-Founder & CTO Leapter) AI coding is fast. We're generating more code than ever. But more code means more code to verify, and agentic workflows are scaling that gap faster than review processes can keep up. The bottleneck didn't disappear. It moved from writing code to verifying logic. For most generated code, you can ship, test, and iterate. But what if we need to be sure? What about the code that runs our financial systems or decides if you qualify for a loan? It has to be right. Hope is not a strategy, we need to better ways to review code. In this talk Robert will share his recent innovations, experiments and insights with you. **About Robert:** Robert Werner is the CTO of an AI startup dedicated to shaping the future of AI-native software development. He has over 20 years experience focussed on Software Engineering, Developer Experience and Transformational Platform Engineering, across Fortune 500 companies and FinTechs. **Talk 2: Narrative Engineering: What Cognitive Science Actually Tells Us About Building with LLMs** (Sal Kimmich, Security Architect at Gadfly AI) We keep treating LLMs like search engines that hallucinate. That is the wrong category, and it produces the wrong engineering. LLMs are narrative generators. They do not retrieve facts or execute logic. They complete stories. That distinction is not philosophical. It determines what kind of system you can build with them and what kind you cannot. Neuroscience has been studying probabilistic, distributed, narrative-generating systems for decades. Most of the LLM engineering field is ignoring that work. This talk walks through cyberneutics, an open source methodology and repository built on the premise that we need a new engineering discipline for narrative computing the way software engineering emerged from symbolic computing. The theoretical foundations come from second-order cybernetics, distributed cognition, and Minsky's Society of Mind. The empirical validation comes from 2025 mechanistic interpretability research showing that reasoning models internally simulate multi-agent dialogue to reason better. The practical techniques come from iterative practice: adversarial committees, pipeline algebra with formal quality propagation, observer-aware interaction design. Three real lessons for practitioners building agentic systems: reliability is a property of the pipeline, not the prompt; repetition is latent space exploration, not failure; and if you want auditable AI reasoning, you need to externalise the dialogue structure, because the transcript is the explainability artifact. The discipline does not exist yet. This is what building it looks like. **About Sal:** Sal is a developer advocate for open source and passionate about helping engineers, ethical hackers and digital enthusiasts understand the complexity of modern software development. With over a decade of experience as building cloud-native machine learning pipelines in the healthcare and tech for good sectors, their work is now focused on filling the cracks in the open source software supply chain to build a better digital future for all of us. **Thanks!** We'd like to thank our sponsors [Leapter ](http://leapter.com/)and AutogenAI for making this event possible. **Code of Conduct** This event has a code of conduct that you can [review here.](https://aifortherestofus.live/code-of-conduct) By joining the community and registering for this event you agree to abide by our code of conduct. **Providing Your Name and Email** To register for this event you'll be asked to provide your email address.

Join us for an informal evening of experimenting, building, and sharing ideas around Umbraco and AI. Whether you're curious about AI-powered content generation, the Umbraco MCP Server, AI-assisted development workflows, or other AI innovations in Umbraco - this is your chance to experiment, learn, and build alongside fellow community members in a relaxed, supportive environment. Bring your laptop, your curiosity, and anything you’ve been meaning to try. You can come with a specific idea, jump into something with others, or just tinker and learn as you go. There’s no strict agenda, just a relaxed space to collaborate, swap ideas, and make progress together. We’ll kick things off with a quick intro, then open the floor for hacking, discussion, and demos. If you end up building something cool (or even just interesting), you’ll have the chance to share it with the group at the end. **EVENT HOSTS** [Novicell](https://www.novicell.com/uk/services/software-development/umbraco/) (Umbraco Gold Partner) have kindly agreed to provide refreshments and host us for the evening in their offices in Shoreditch. If you think you will be making it, please sign up ASAP.

If you arrive between 6:00 and 6:15pm there will be someone to meet you in reception with instructions. If you arrive later you might need to phone us to be let in: we shall email all attendees with the contact numbers on the day. **CODE OF CONDUCT** Please read the [Code of Conduct](https://bit.ly/UmbLondonCodeOfConduct) for all our events.

Reportage photography or visual narrative photography is the art of telling the story of an event or location through photographs. It is based on photojournalism and when carried out properly, reportage photography will provide a comprehensive collection of photographs that will form a story of the subject. In this edition of this storytelling workshop we will choose from a selection of topics occurring around Chinatown in order to create a collection of photo stories. It is going to be challenging but also full of discovery. You will learn how to report and tell your story from beginning to end and then given a brief and a series of exercises to help you tell your story. WHAT YOU WILL LEARN * How to create a visual narrative * What makes a good story and how to show it visually * How to tell a story with a series of photographic images * Improve your composition skills to create impactful images EXPERIENCE LEVEL * Beginner/Refresher EQUIPMENT * Any camera including mobile phone * Any lens CONTACT * Alex 07956 264049 VENICE PHOTOGRAPHY WEEKEND - Oct 2026 [https://www.meetup.com/londonphotographic/events/313109100/](https://www.meetup.com/londonphotographic/events/313109100/) UPCOMING EVENTS [www.meetup.com/londonphotographic/events](http://www.meetup.com/londonphotographic/events)

Today we'll be looking at the work of the Italian artist Caravaggio. Caravaggio adopted *chiaroscuro* in his paintings in the 16th century- his work beautifully combines a realistic view of the human state- physical and emotional- with a dramatic use of lighting. *Chiaroscuro* is an Italian term referencing the contrast of light (chiar) and dark (oscuro) to model three-dimensional forms. It’s a style that has quite dramatic results and one that photographers can learn a lot amount about lighting from studying. **Join us for a workshop in 2 parts:** * Informative session on the incredibly interesting life and work of Caravaggio * Shoot chiaroscuro style * We will also discuss street photography tips EQUIPMENT: * Any camera * Any lens such as a standard 18-55, 24-70mm etc. OTHER ESSENTIALS * A fun and experimental attitude! TRAVEL * As usual check TFL website for any issues that may delay your journey CONTACT * Alex 07956 264049 **UPCOMING EVENTS** **VENICE PHOTOGRAPHY WEEKEND - Oct 2026** **[https://www.meetup.com/londonphotographic/events/313109100/](https://www.meetup.com/londonphotographic/events/313109100/)** **UPCOMING EVENTS** **[https://www.meetup.com/londonphotographic/events/calendar](https://www.meetup.com/londonphotographic/events/calendar)**

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
