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).

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.

**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 folks! Welcome to our February Cloud Native London meetup! Join us to hear from our three great speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube! 6:00 Pizza and drinks 6:30 Welcome 6:45 Stop Running Mystery Meat in Production (Jeroen van Erp, SUSE) 7:15 Platform Wars: The Battle Between Golden Paths and Spaghetti Pipelines (Prithvi Raj, Mirantis) 7:45 Break 8:00 Beyond Chatbots: How AI Agents and Humanoids Are Shaping a New Era (Akshya Prakkash, Urban Care Community) 8:30 Wrap up Sponsors: TechShack, Cloudsmith, SUSE See you there! Cheryl (@oicheryl) **Stop Running Mystery Meat in Production (Jeroen van Erp, SUSE)** We have all been there. You need a database or a quick node environment, so you throw FROM node:latest into your Dockerfile and deploy. It works, but you have just introduced a black box into your Kubernetes cluster. For the Developer, it’s a quick fix. For the Platform Engineer, it’s a nightmare. Most upstream images from public registries are a roll of the dice. They come pre-packed with critical vulnerabilities, unknown binaries, and bloated libraries that you didn’t ask for and definitely don’t want running in your secure environment. In a world of Zero Trust, why are we trusting random upstream maintainers with the keys to our infrastructure? *Jeroen van Erp is a technology evangelist at SUSE, specializing in the observability platform. With a rich background spanning engineering, architecture and product management, Jeroen brings over a decade of experience in the DevOps space. Before joining SUSE, he played a pivotal role as technical slliance director at StackState, where he helped shape the future of observability. As a trainer and speaker, Jeroen is known for his ability to distill complex technical concepts into actionable insights. He is passionate about solving challenging technical problems, whether through mentoring or hands-on involvement. An active contributor to the open source community, Jeroen maintains several highly starred repositories. When he’s not diving into the latest technology trends, Jeroen enjoys spending time on his mini-farm, where he cares for his sheep and shares his love for rural life.* *https://www.linkedin.com/in/jvanerp/* **Platform Wars: The Battle Between Golden Paths and Spaghetti Pipelines (Prithvi Raj, Mirantis)** Internal developer platforms promised golden paths: streamlined, reliable routes for delivering software. Yet too often, they lead platform engineers into a tangled web of YAML, Bash scripts, and tool sprawl. The true crisis today isn't implementing the idea of platform engineering but navigating through platform democracy challenges. The true Darth Vader moments in platform engineering appear when good intentions turn dark: developer experience suffers, and open-source tools quietly become villains to velocity. This session aims to dive deeper into the open-source tooling and cloud-native strategies that mitigate the platform crisis. We’ll examine how to maintain the Jedi discipline of paved paths or fall into spaghetti-pipeline chaos while chasing the perfect delivery workflow. Through real-world stories and anti-patterns, we’ll explore the light and dark sides of OSS-powered platform engineering and help you uncover who the true Darth Vader of your stack might be. *Prithvi Raj is a Community Manager & Developer Advocate at Mirantis working with the Open Source Program Office team. He is a CNCF Ambassador with 5+ years of experience who helped scale a CNCF incubating project in LitmusChaos and runs the Platform & Resilience Engineering Meetup group. He is an active member of SIG Project Reviews and currently leads community efforts for the k0s project, k0rdent, OpenSDN, and other OSS initiatives Mirantis contributes to.* *He is a co-organizer for KCD Bengaluru and previously organized Chaos Carnival, LitmusChaosCon and KCD Chennai. He was previously at Harness, ChaosNative, and MayaData.* **Beyond Chatbots: How AI Agents and Humanoids Are Shaping a New Era (Akshya Prakkash, Urban Care Community)** Chatbots introduced the world to AI, but they are only the starting point. A new wave of systems - AI agents and humanoid technologies is shifting AI from conversation to action. This talk explores how AI is evolving beyond text-based interaction into systems that can perceive environments, make decisions and operate in the real world. Drawing from hands-on experience with agent-based AI projects and robotic platforms in community and care settings, we’ll examine what makes these systems different, the challenges of trust and why this shift represents a new era for human-AI interaction. Join this session to see how AI is beginning to act, not just respond. *BSc Computer Science Hons @ UOW & Software Developer at UCC* *LinkedIn : https://www.linkedin.com/in/akshya-pv/* *Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.*

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia. * **Topics**: * **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article. * **Images**: Adding images using the img tag and attributes like src, alt, width, and height. * **Multimedia**: Embedding audio and video content using the audio and video tags. * **File and Folder Structure**: Best practices for organizing project files and managing file paths. * **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file. **Class 3: Forms and User Input** This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input. * **Topics**: * **Form Basics**: Using the form element, action and method attributes. * **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit). * **Form Elements**: Utilizing label, textarea, select, option, and button. * **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern. * **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation. **Class 4: Introduction to CSS3 and Basic Styling** The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible. * **Topics**: * **CSS Fundamentals**: The role of CSS, selectors, properties, and values. * **Integrating CSS**: Using inline, internal, and external style sheets. * **The Box Model**: Understanding margin, padding, border, and content for basic layout. * **Basic Styling**: Changing colors, fonts, and text alignment. * **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels. * **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2.

Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines.
