This June we're at FundApps offices in HYLO, Bunhill Row. Chris Simon's back in town, and will be joining us to talk about streams and queues; plus Tiago Sousa from SteelEye will be talking about the work they're doing around using AI in comms surveillance. Our hosts at FundApps will be providing drinks and snacks, and there will be plenty of time to chat beforehand and in the pub afterwards. **Chris Simon: It's like 10,000 streams when what you need is a queue** *🎶🎵 A new dev team adopted E-D-A* *Got head of line blocking, on their very first day* *Isn't it ironic, don't you think 🎶🎵* The last few years have seen widespread adoption of Event-Driven Architecture, supported by DDD practices such as event storming. But what does that orange sticky note become when we start implementing our design? Common implementation choices include event sourcing, streaming platforms like Kafka and queuing systems like RabbitMQ. Unfortunately not every orange sticky note has the same operational needs, and many teams remain confused about the differences between these options, resulting in the selection of the wrong paradigm for their needs. This can lead to unnecessary complexity & operational challenges such as head of line blocking, dropped messages, challenges dealing with failed messages, difficulty with adaptive scaling and inadvertently increasing coupling between services. In this talk we'll bring that orange sticky note into the runtime of our system. We’ll start with a deep dive into the similarities and differences between event streaming platforms such as Kafka and queueing systems such as RabbitMq, Azure Service Bus & AWS SNS/SQS. We’ll then look at ways to assess your orange sticky notes to work out which messaging and persistence paradigms suit each one, helping you build more resilient, scalable and loosely coupled event-driven architectures. **Tiago Sousa: AI in Comms Surveillance** In this talk, Tiago shares what it's actually like to build AI for communications surveillance at SteelEye. Financial firms are required to monitor and flag communications for compliance, but making AI work reliably in that context is harder than it sounds. He'll walk through real examples from the trenches: what worked, what didn't, and what he'd do differently. **Tiago Sousa** is a Staff Data Engineer and AI Lead at SteelEye - a platform that helps financial firms monitor and flag communications and trades to stay compliant with regulations. He's spent the last five years building the data and AI systems that make that work. Before that, he did research in bioinformatics, which means he came into fintech from an unusual angle and has the scars to prove it. He's based in Braga, Portugal.

Script Reading, Improvisation, Voice Projection, Games, Public Speaking and audition techniques will be some of the points covered over the coming terms. Drama is ideal for building confidence, helping with articulation and developing presentation skills. It is also a lot of fun! The classes have built up over the last five years and are run by Mario Renzullo, who was an original member of the famed Anna Scher Theatre and made his professional debut in 1970, and went on to have many lead TV, film and theatre roles. Mario founded the theatrical agency Smart Management, which has been running for over twenty years. The classes are open to a wide age range and welcome those new to acting as well as those with professional acting experience. Typically, between 12 and 20 people join us each week, creating a lively and engaging group dynamic. Venue: The Angel Church, Chadwell Street EC1R 1XA Five minutes’ walk from the Angel tube station. Thursday evenings at 7.00 pm – 8.30 pm. Fee: £10.00 cash per session. For more information, please email your contact details to: [smartmanagement@btconnect.com](mailto:smartmanagement@btconnect.com)

Ready to get outside? Our Thursday morning session in Dulwich park is back! At this moment we can meet with up to 30 people (of more than two households) to do outdoor exercise and walks. However, i like to keep our exercise groups small, so I have set the maximum participants at 12. For now this walk is for our experienced Nordic Walkers only, who already used to Nordic Walk with us regularly before Covid 19 kept us indoors, and who have their own Nordic Walking poles. As this session is outdoors, we will not ask you to wear a face mask, but we do ask you to keep 2 meters apart. Some of our walkers might be immune compromised or more at risk, so please help us keep everyone safe! Please do not come to the session and stay at home if: - you know you have been in contact - in the last 2 weeks- with someone with symptoms of possible Covid, or if you have been in contact with someone who tested positive. - you have any of the following symptoms: (new) Loss of smell/taste, Persistent cough, Fatigue, Loss of appetite, Skin rash, Hives, Fever, Severe muscle pain, Shortness of breath, Diarrhoea, Delirium, Abdominal pain, Chest pain, Hoarse voice, Eye soreness, Sore or painful throat, Nausea or vomiting, Headache, Dizziness or light headedness We meet by the cafe in the middle of the park. Session Price: £10 per session, £89 for a 10-session card or £70 unlimited sessions per month. Session cards and pay Monthly can be used in any of our outdoor walks or indoor Zoom classes sessions (except for the Parkinson's sessions). Pay What Works: The price shown above is the “true” value of the session that best reflects the work I put into preparing and leading your session. However, I understand that not everyone can afford to pay full price, and I don’t want that to stop you from joining us. In an effort to find a balance between more financial accessibility and sustainable pricing, I now offer a “Pay What Works” model. This allows for financial flexibility while still valuing and respecting the work and energy I provide in creating and delivering these classes. Then send an email to ailien@fitandhappyoutdoors.com with the heading “INVOICE please”- followed by “FAHO 1” to pay full price as quoted below, “FAHO 2”, for 20% off, or “FAHO 3” for 50% off. Pllease do tell me if you want to pay for 10 sessions, or if you’d like to pay monthly. I prefer payment by bank transfer, but if that is not possible you could pay in cash. No cheques please, the queues by the banks are just too long. We walk in all safe weather conditions – if a walk is cancelled, we will contact you to let you know. Please check for text messages or Meetup messages before leaving home!

**Agentic Engineering with Alibaba Cloud** ***Models, Memory, Tooling & Deployment for Production AI Systems*** 🙏 Please note Thant we only taking registrations from the [LUMA](https://luma.com/hdygxmyx) for this event. If you are RSVP on meetup, you also need to register on [LUMA](https://luma.com/hdygxmyx) LUMA LINK: https://luma.com/hdygxmyx Agentic AI is rapidly moving from experimentation to production. Building successful AI systems today requires much more than selecting a foundation model. Teams must make decisions around model strategy, RAG, memory architecture, enterprise integrations, deployment infrastructure, governance, performance, cost, reliability, and long-term scalability. Join **[London Agentic AI](https://londonagenticai.com/?utm_source=luma)** and **[Alibaba Cloud](https://www.alibabacloud.com/?utm_source=luma)** for an evening dedicated to the engineering behind modern AI systems along with talks from leadership of [Tomoro AI](https://tomoro.ai/?utm_source=luma) and [Recombine AI](https://recombine.ai/?utm_source=luma). This event brings together AI engineers, founders, technical leaders, and practitioners, CEO/CTOs who are actively building and deploying production AI systems across startups and entprises. If you are building AI-native products, deploying enterprise AI solutions, evaluating open-weight models, or scaling agentic systems into production, this event will provide practical knowledge from people solving these challenges every day. **Speakers** Talk 1: [Alex McLeman](https://www.linkedin.com/in/alexmcleman/?utm_source=luma) :**Strategic Solutions Architect, Alibaba Cloud** Alibaba Cloud Strategic Solutions Architect, will walking the model portfolio behind Alibaba Cloud Model Studio, one of the broadest open-weight catalogues in production today. You'll leave with a clear view of which model fits which workload (RAG, agents, fine-tuning, multimodal pipelines, on-prem inference economics), and where Apache 2.0 licensing reshapes your build vs. buy math. Engineering-led conversation. Bring questions. Talk: 2 [Rishabh Sagar](https://www.linkedin.com/in/rish-sagar/?utm_source=luma): **Co-founder, Tomoro AI** **AI Systems That Remember: Memory's Role within the Agent Architecture** Memory is what separates a stateless model call from a genuinely useful AI system. In this session, we'll explore why persistent memory is becoming a foundational layer of the harness around modern agentic systems, the infrastructure that shapes how a model behaves without ever touching its weights. Get this right, and you build experiences that compound in value over time. Talk 3: [Stas Bichenko](https://www.linkedin.com/in/stas-bichenko/?utm_source=luma) : **CEO, Recombine AI** **Auto-generating SDKs for conversational AI** Conversational AI agents are only as good as the data they can access. How do you connect your voice AI to complex enterprise-grade systems? How do you let the non-technical people control the agents that can make API calls? How do you keep conversations natural with high-latency API calls. It's easier than you might think. I'll go through the approach we've chosen at Recombine: generating the AI agent's SDKs automatically from API docs. **Panel Discussion & Audience Q&A** Deploying Agentic AI in Production: What Actually Works?Following the talks, join an interactive panel discussion featuring all speakers, followed by audience Q&A. Bring your questions and engage directly with leaders building and deploying AI systems today. **What You'll Learn** 🧠 How memory architectures are becoming a foundational layer of modern AI systems 📦 How to evaluate and deploy models for agentic applications, RAG systems, multimodal workloads, and enterprise use cases 🛠️ How AI agents can safely and effectively connect to enterprise systems through APIs, tooling, and integrations 🚀 Deployment strategies, infrastructure considerations, and operational best practices for production AI systems 💰 Model selection, cost optimization, inference economics, and build versus buy decisions 🌐 How open-weight ecosystems such as Qwen are influencing the future of enterprise AI adoption **Why Attend?** This is a technical and engineering-focused event designed for people building real AI systems.

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

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!

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9
