Over the past year, generative AI has gone from novelty to infrastructure. But while most people are still treating tools like ChatGPT as clever calculators, a small group are quietly rebuilding how they work around agentic systems, automated workflows, and personal knowledge bases. This talk is for anyone who suspects there is a big gap between “using AI” and actually being at the frontier. In this session, our own host Dr Manuel Corpas will share **10 concrete patterns** he has used to build a personal AI stack that now runs 24/7 alongside his research and teaching. Rather than a product demo or a hype talk, this will be a practitioner’s tour of what changes when you move away from simply ad-hoc promptings. Manuel will keep the examples grounded in genomics, health data and academic work, with patterns directly transferable to industry, clinical and data‑intensive roles. There will be time for Q&A and informal discussion afterwards (as usual, we’ll migrate to the pub after the main session). **About the speaker** Dr Manuel Corpas is a globally recognized genomicist and health data scientist whose work has advanced the frontiers of equity in precision medicine. His research spans population genomics, pharmacogenomics, and biobanking, with a longstanding commitment to underserved and underrepresented populations. As President of the Spanish Congress of Genomic Medicine, he leads the largest Spanish-speaking platform for genomic health equity. He has been a driving force behind major sequencing efforts such as the Peruvian Genome Project, which expands global reference datasets to include diverse Indigenous and Latin American populations. He has contributed to widely adopted clinical and open‑source tools, including DECIPHER for rare disease diagnosis and BioJS for genomic data visualization. Approximate schedule (@University of Westminster – Cavendish Campus): * 18:30 – doors open * 18:45 – chitchat, announcements * 19:00 – talk starts * 19:45 – talk ends, adjourn to pub Please RSVP at least the day before, and make sure your Meetup name is recognisable (e.g. “J Smith” rather than “weaselstabber”) so reception can match you to the attendee list and direct you to the room.

## DevOps Society Meetup with EDF **Location:** EDF UK, Nova North, 11 Bressenden Place London, SW1E 5BY **Time:** Doors open at 6PM **Drinks, snacks, talks, and networking.** We’re excited to invite you to our first in-person **DevOps Society Meetup** of 2026, proudly **sponsored by EDF**. This event brings together the DevOps, SRE, and cloud engineering community for an evening of honest conversations, real-world lessons, and networking with people who’ve actually done the work. A huge thank you to **EDF** for sponsoring the event and for providing the venue, refreshments, and support for our community. *** ## ️ Format of the Meetup: 6:00pm – 6:30pm — Networking on arrival, with food and drinks provided by EDF 6:30pm – 7:10pm — First speaker + Q&A 7:10pm – 7:20pm — Break for refreshments and networking 7:20pm – 8:00pm — Second speaker + Q&A 8:00pm onwards — More networking at the venue, then at a nearby pub. *Timings can vary slightly depending on Q&A.* *** We’re delighted to welcome **two fantastic speakers** to this EDF-hosted DevOps Society meetup. *** ## SPEAKER 1 – Steve Bowerman **Principal Software Engineer, EDF** ### Bio Steve is a technologist and thought leader with **25 years in the industry**, including **20 years in the utilities sector**, spanning startups through to large, established enterprises. Since stepping into the role of **Principal Software Engineer at EDF**, Steve has played a key role in reviewing and overhauling EDF’s approach to software engineering - bringing critical capabilities in-house and aligning teams with modern **DevOps and SRE principles**. His work focuses on long-term, sustainable transformation rather than tooling churn, helping large organisations evolve how they build, operate, and scale software. *** ### Talk Title **Rebooting the Enterprise: The DevOps Way** ### Talk Intro Building a DevOps mindset in a startup is relatively easy - it’s often the default DNA of modern engineering teams. Doing the same in a **large enterprise** is a very different challenge. In this talk, Steve will take you through **five years of transformation in 15 minutes**. He’ll share how EDF approached enterprise DevOps adoption, where things failed (and why), what ultimately worked, and the lessons learned along the way. Spoiler: **technology was the least difficult part**. This session is ideal for engineers, platform teams, and leaders working in complex organisations who want a realistic view of what enterprise DevOps transformation actually looks like. *** ## SPEAKER 2 – Matteo Emili **Director of Software Engineering, Avanade** **Bio** Matteo Emili is a Director of Software Engineering at Avanade UK and Ireland, leading the talent in Software Engineering and always looking at new ways of applying technology to solve business problems. He is a passionate Agile advocate and a technologist at heart, a Cloud Architect who is always driven by using technology as a vehicle for change and continuous improvement. A Microsoft MVP since 2010 (currently in the Azure DevOps and GitHub category), he enjoys sharing back as much as he can with the worldwide technical communities – especially within Agile and DevOps. He has founded several User Groups around Europe and he is a regular speaker at meetups and conferences. ### Talk Title **From Vibe Coding to Agentic Engineering: A Step-by-Step Guide** ### Talk Bio AI-augmented software development is evolving. What started as *“vibe coding”* \- intuition\-driven\, creative experimentation with AI \- is now moving toward **agentic engineering**, a more governed and intentional approach where AI agents actively collaborate with developers while enforcing best practices and organisational standards. In this session, Matteo explores how teams can transition from unstructured AI experimentation to **agentic workflows** that balance creativity with accountability. You’ll learn how agentic engineering enables: * Faster development without sacrificing quality * Built-in governance and standards * AI collaboration that scales across teams * A practical path from experimentation to production-ready AI-assisted engineering This talk offers a clear, pragmatic view of how AI will reshape software engineering in the years ahead - and how teams can adopt it responsibly. *** Please **RSVP to secure your spot**. Spaces are limited and available on a **first-come, first-served** basis. We’re really looking forward to getting the community back together again for our first event of 2026.

# ​Beginners Hands-On Workshop: Demystifying OpenClaw, the New Personal AI Everyone's Talking About: The Good, The Bad & The Sloppy **Registration to this event is only valid through the Luma platform: [https://luma.com/wy7xdrca?utm_source=meetup-dot-com](https://luma.com/wy7xdrca?utm_source=meetup-dot-com)** Hello everyone! Due to popular demand we are going to run a full OpenClaw (previously known as Clawdbot/Moltbot) event! Join us on **Thursday, 26 Feb**. This would be our 5th event in our series of **local-first, open-source** **AIs** therefore we will try our best to avoid connecting OpenClaw to any cloud-based AI model and keep everything private. We will focus on the good (useful ways of automating things with it), the bad (the rough edges of OpenClaw, security wise) and the sloppy (the danger of creating too much low-quality content especially since the Internet is full of that type of content). This workshop is open to all levels, from beginners to experts. Bring your laptop (make sure it's fully charged if possible as local LLMs tend to be power-hungry), and, don't forget to bring your coding gear (hoodie). We will try to run A.I. models on the mobile phone as well so feel free to bring your phone fully charged with a little bit of free storage space. This workshop will be accompanied by Sam W. & Joon-sang L. (the founders of Pentaform). Since the recommended way to run OpenClaw is on its own dedicated hardware and since there are people at Encode specialised in building mini-PCs, what better way to close the night than to hear about various hardware options and to see what Pentaform is building. See you there! *** ## Prerequisite First and foremost\*\*, VERY IMPORTANT\*\*, a VM (Virtual Machine) system like Docker/UTM for MacOs or WSL for Windows. Lastly, a local install of Ollama / LMStudio (but if you don't have any of that, don't worry, come a bit early and we will help set you up). Ideally you should check the slides from the previous event to set up Ollama locally: [https://andysign.github.io/ai-london-01/](https://andysign.github.io/ai-london-01/) Not related but still interesting, the second slide deck about flows with LangFlow (you should know how to access it if you've been to the last workshop, if not join the Discord and ask us): [https://andysign.github.io/ai-london-02/](https://andysign.github.io/ai-london-02/) There is a third deck, also not related (about personal RAGs w/ AnythingLLM): [https://andysign.github.io/ai-london-03/](https://andysign.github.io/ai-london-03/) And a forth deck, this one is slightly related (about AI-powered browsers): [https://andysign.github.io/ai-london-04/](https://andysign.github.io/ai-london-04/) *** ## Agenda for the evening (Subject to change) **18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. **18:30 - 18:45 Introductions (What is Local-First?)** Learn about self-hosted, local AI models and why we use them. **18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). **19:40 - 20:15 Pentaform and Local AI** **20:15 - 21:00 Networking** **21:00 - Closing remarks and follow-up** **END:** Carry on the fun at a nearby pub which is right around the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**. [Encode Club ](http://encode.club)has spent over five years fostering a global community of developers, researchers, and founders in Web3, AI, and emerging technologies. The [Encode Hub](http://hub.encode.club) brings everything together under one roof, providing a dedicated environment for collaboration and innovation through meetups, co-working, and in-person events. *** ##

**🕙 Time** We meet at **10:00 AM** and will start walking shortly after. The walk lasts around **60–75 minutes**. **📍 Where to Meet** We’ll meet at the **Clapham Common Bandstand**. A message with the **exact spot and a visual cue** (what I’m wearing) will be posted in the event comments on the morning of the walk.

Today we'll be looking at the work of the Italian artist Caravaggio. Caravaggio adopted *chiaroscuro* lighting in his paintings in the 16th century. *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 use to create dramatic images. **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 **PAYMENT OPTIONS** * **PayPal via RSVP** * The Meetup transaction fee will be added. and you'll automatically be added to attend * **Send £25 via PayPal** to \*\*[creativebeansproductions@gmail.com**](http://creativebeansproductions@gmail.com%2A%2A/) with no extra fee. * Send us a text or comment below and we will add you to the event attendee list. 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 VENICE PHOTOGRAPHY WEEKEND - Oct 2026 [https://www.meetup.com/londonphotographicopa/events/313109095](https://www.meetup.com/londonphotographicopa/events/313109095) UPCOMING EVENTS [www.meetup.com/londonphotographicopa/events](http://www.meetup.com/londonphotographicopa/events)

**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 📓 **HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/Ja2H9lXYtWX8RdCKHw6qNK), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 13:45-14:00 - People arrive and chat, get to know each other before the ‘official' start. * 14:00-14:05 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 14:05-14:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 14:45 - We do a group conclusion of the things we discussed, and then we typically take a photo and go on our way :) If you don't want to be in the group photo, there's no pressure, it's just a way to close out the meeting. You are free to walk around Calthorpe's Community Gardens afterwards. **🧧PRICING?** Practical Philosophy Club is FREE to attend, and we operate on donations. Calthorpe Cabin costs £40 per hour to rent. If you'd like to donate to support the cost of the location, that helps keep our group self-sustaining. Donations are 100% voluntary, but your contribution is appreciated! QR codes to donate and a donation jar will be present. Calthorpe charges £4 per person for tea's and coffees and are paid by the individual should they wish to have them. **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/Ja2H9lXYtWX8RdCKHw6qNK). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/Ja2H9lXYtWX8RdCKHw6qNK) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment. **PRACTICAL PHILOSOPHY - Making Philosophy Available To All.** ✨ Practical Philosophy hosts weekly, in-person meetups in 25+ countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://chat.whatsapp.com/Ja2H9lXYtWX8RdCKHw6qNK) 👈 Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub/?hl=en) 👈 Our [website](https://www.practicalphilosophy.club) 👈

**Autumn Term 2025** Spring Term Sunday, March 1st 10.00am- 4.00pm **Tutor: Daisy Perkins** **Dancer and model: Flora Baltz** *Cost £95* Drawing and image making often works best when the whole of our mind-body is engaged. * Discover new ways of drawing * Respond to live movement with line, rhythm, gesture, and mass. * Experiment with materials and scale, from fluid ink washes to large collaborative drawings, blending abstraction with the figure. * Develop a resolved final work and leave with a fresh, embodied approach to mark-making that you can carry into your own practice. During this workshop we will become interested in how we can connect with movement, and how we can use this to make more powerful uncontrived visual statements. * **Notice how your own body feels and responds** * **Let physical sensation, rhythm, and inner state guide mark-making** * **Feel movement in the body before translating it into drawing** This workshop brings together the disciplines of drawing and dance to explore new ways of seeing, sensing, and making. Guided by Daisy and working with a dancer, participants will step beyond conventional figure drawing into a more embodied, responsive practice. You’ll begin by treating the hand as a seismograph—a recorder of rhythm and presence rather than mere outline—using movement awareness, gestural drawing, and collective mark-making to open up expressive possibilities. You’ll develop from free-flowing experiments into a resolved final work that blends abstraction, gesture, and form. Along the way, you’ll try out a variety of dry and wet media and experiment with mass, line, erasure, expression, disruption and layering, as you learn to capture both motion and stillness. With space for reflection and discussion built in, the workshop offers not only technical exploration but also a deepening sense of the creative process. Attendees will leave with fresh approaches to drawing the figure, a body of experimental works, and the beginnings of a personal language informed by movement, rhythm, and embodied experience. * We will be working with a nude dancer * Materials provided * We plan to share a vegetarian lunch £12, optional.

This is just a studio session, with no Zoom. We will have a life model in the same pose for three hours in the afternoon, usually for two consecutive weeks. This is an untutored session run by a professional painter who will always be happy to give advice. Other than model breaks, usually every 25 minutes, we break for tea and cake at 3.30pm for twenty minutes. Our studio is divided up into workstations or ‘positions’ and whilst each position has a good view of the model many artists prefer to be front and centre. (Actually, you often get a more interesting composition to the side of the room). You can also just turn up at the studio on spec and find a place to paint. Our studio has a light and friendly atmosphere. Whether you're a beginner or an experienced painter, come and paint with us! We have a wonderful community of artists who join us each week. Costs From £20 – £25 per session [More info and bookings here](https://www.dulwichartgroup.co.uk/product/saturday-morning-life-painting-drawing/)

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
