Despite the high dimensionality of datasets typically encountered in real-world scenarios such as fluid dynamics or weather & climate, these are typically low-rank: there are a few dominant patterns that explain the high dimensionality. The SVD is a useful dimensionality reduction technique for such systems, and has the advantages of being explainable and computationally efficient. SVD-ROM enables the application of SVD-based machine learning methods such as Principal Component Analysis (PCA), Proper Orthogonal Decomposition (POD) or Dynamic Mode Decomposition (DMD) on massive datasets. We employ Dask for parallel and out-of-core computation, Xarray for labelled N-dimensional arrays, and data formats such as Zarr and NetCDF for chunked storage of large arrays. We have developed SVD-ROM keeping user-friendliness in mind, exposing a Python API that enables the straightforward application of methods such as pre-processing, model fitting, reconstruction and forecasting. Additionally, Dask makes code portability across laptop, HPC clusters or cloud straightforward, enabling the user to run SVD-ROM on different computational environments with minimal changes. The development of SVD-ROM has also resulted in multiple contributions to PyDMD, the most popular open source Python package for the application of DMD. In this talk we show how we can fit a DMD model to a global weather dataset tens of GB in size and produce an accurate sub-seasonal forecast (6 weeks ahead) on a laptop in just a few minutes. 2. **From Zero to HyperPod: Cutting Infrastructure Complexity for Distributed Model Training on AWS** - [Anton Nazaruk](anton.e.nazaruk@gmail.com) Training state‑of‑the‑art models often stalls on two pain points: GPU availability and infrastructure complexity. In this 40‑minute, practitioner‑level session, I will demystify the fastest, most cost‑effective routes to dedicated NVIDIA H100 and B200 clusters on AWS. We will compare EC2 On‑Demand, Spot, Savings Plans, EC2 Capacity Blocks, and the new SageMaker Training Plans with HyperPod, showing where each shines for research, production training, and massive fine‑tunes. A live demo will provision a 256‑GPU HyperPod, walk through distributed‑training set‑up with Deep Speed + PyTorch, and showcase built‑in checkpointing and automatic node recovery. Attendees will leave with: 1) a decision framework for picking the right reservation model, 2) reference Terraform and CDK snippets to launch clusters in minutes, and 3) cost‑optimisation tips that have saved our clients up to 35% versus unmanaged fleets. Biggest focus on practical architectures, benchmarks, and war stories you can apply the next day. **Lightning Talks** 1. **Agentic, Agentic AI for Personalized Care — Lessons and Challenges from Holisticare.io - Mojtaba Kargar** 2. **Mapping the International PyData Community featuring Web Scraping and Data Wrangling - [Hugh Evans](https://www.linkedin.com/in/hugh-evans-dev/)** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** Doors open at **6.30 pm** (get there early as you'll need to sign in with building security). Talks start at **7:00 pm**, with drinks afterwards from **9:00 pm** at The Banker (EC4).

**Never tried Grafana before? This workshop is for you!** APIs are the backbone of modern software development. They power everything from mobile apps to internal tools, but let’s be honest, reading through raw JSON or API responses isn’t the most exciting way to work with data. What if you could turn that data into clean, interactive graphs without writing a ton of custom code or spinning up a backend server? That’s where Grafana comes in! **Grafana** is an open-source data visualisation and observability platform that lets you create interactive, real-time dashboards from various data sources. It’s best known for visualising metrics from systems like Prometheus or InfluxDB, but thanks to its plugin ecosystem, it can do much more. **In this fun, beginner-friendly workshop, we’ll:** * Explore what Grafana is all about * Connect to an API using the Grafana Infinity plugin * Configure a simple query and pull the data into Grafana * Turn that data into a beautiful dashboard with different panel types **No prior knowledge of Grafana** is required as this session is beginner-friendly, but bring your **(well charged) laptops** as this will be a hands-on session!

Hi JavaScript London, We're thrilled to host the 1st meet-up of 2026!! We are kicking off the year with Omnea hosting at Wave Talent's offices in Shoreditch. We have some fantastic tech talks lined up, there will be plenty of pizzas 🍕, and of course drinks 🍻, plus plenty of networking with fellow tech enthusiasts. Don't miss out on a night of great conversations and new connections! **Address:** 14 Bonhill Street London, EC2A 4BX **Registration -** You know the drill by now!! Please register via Meetup and also via the website as we need to give a list of attendees on the night. [https://www.javascriptlondon.com/](https://www.javascriptlondon.com/) **Talks:** **1st Talk:** [Tynan Byrne](https://www.linkedin.com/in/tynanbyrne/) \- Software Engineer at Omnea\. **Topic: "Stop Guessing: How to Actually Know Your AI Feature Isn't Useless"**" You tweaked your AI prompt. Your teammate suggested adding markdown. Your manager wants to try Claude instead of GPT-4. Is it better now? Worse? Nobody actually knows. In this talk, I'll show you how to use an eval loop to iterate on AI features with confidence. We'll take a simple AI tool and improve it live - changing prompts, running tests, and watching scores update in real-time. You'll see which changes actually help and which just look different. Then, I'll show you how we do this at scale at Omnea: hundreds of test cases, continuous experimentation, big AI features used by the likes of Monzo and Spotify. You'll leave knowing how to judge your AI features with data, not just vibes." **2nd Talk:** [N. Nain](https://www.linkedin.com/in/nnain/) \- Lead Engineer at Indie Gaming **Topic:** **"Introducing TypeScript into a codebase owned by hardcore C++ / Rust engineers (and the politics involved)"** When I joined an indie gaming studio as Lead Engineer to build a new Web Engineering team, I assumed my biggest challenges would be technical - porting and integrating with an existing Rust and C++ codebase. I was only half right - as it turned out the real challenge wasn’t the code, but the developers behind it! Tonight, I’m not just gonna talk about the two languages I personally love, but the people - and the artificial tribes that formed around them. The technical challenges and misconceptions. The arguments. The (occasional) shouting. And the stranger-than-fiction lengths people went to, just to prove a point. Funny, tragic, and over the top - but everything works out in the end? Welcome to modern software development at work. **Full agenda:** 6:00 PM: Doors Open. Grab a pizza slice, sip a beer, and start chatting with other attendees. 6:30 PM: Welcome remarks by Sam, Richard and Justin 6:35 PM: First talk 7:05 PM: Toilet break 7:15 PM: Second talk 8:00 PM: Closing remarks and an optional pub visit! **Directions to WaveTalent:** The closest train station: Moorgate or Old Street **Sponsor**: **Omnea:** Omnea is a London-based AI-native procurement technology company that builds a platform to streamline how organisations buy goods and services, manage suppliers, and control spend through automated workflows and embedded governance. Founded in 2022 by Ben Freeman and Ben Allen, Omnea replaces slow, manual procurement processes with an intelligent system that lets employees make requests conversationally while routing approvals across finance, legal, IT, and security teams. Since its launch, Omnea has experienced rapid growth, driven by strong enterprise demand for AI-powered procurement solutions. Over the past year the company has grown revenue 5× and more than tripled its headcount, adding high-profile customers across North America and Europe, including Spotify, Albertsons, Wise, Adecco, and MongoDB. Omnea’s growth has been supported by significant venture funding, including a $20 million Series A round led by Accel in 2024 and a $50 million Series B round in September 2025 co-led by Insight Partners and Khosla Ventures, with participation from Accel, Point Nine, First Round Capital and Prosus —bringing total funding to over $75 million to accelerate its vision for AI-powered Supplier Relationship Management (AI-SRM) and expand hiring across the US and UK. Backed by world-class investors and trusted by leaders across tech and enterprise, Omnea is positioned as a fast-growing innovator in the procurement and supplier management space, transforming an often-fragmented business function into a strategic advantage.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.

Connected Westerville Night of Networking flips the script on networking, with surprises and connections that'll make you say, "Who knew networking could be this much fun?!"

Join members of the local UX and Digital Design community for a casual monthly breakfast. There _might_ be a little snow, but there _will_ be effectively infinite serve-yourself coffee, so it evens out if you ask me. Just a reminder, while the other locations are great too, we’re at the Lane Ave one this time.
