GDG Cloud London is thrilled to be partnering with Skyscanner for a deep dive into the world of AI applications in Production. This meet-up is a unique opportunity to connect with fellow AI enthusiasts, industry practitioners, and researchers in a dynamic and interactive setting. We are going to have some pizza and networking at the end! Don't miss out, RSVP now!AGENDA 18:00 - Doors Open & Check-ins 18:30 - Welcome & Intro 18:40 - Ellen Muller - Vectors in the Newsroom: Building Smarter Image Search at the Guardian. When a photo editor searches our image management system for "protest" at 6pm on a deadline, they can't afford to get zero results because the images were captioned "demonstration." Traditional keyword search has no way to know those mean the same thing - and for an archive with inconsistent metadata, that gap matters. This talk is about how we added semantic search to the Grid (the Guardian's open source image management system) using embeddings and vector similarity. We'll dig into how vector spaces let you encode meaning rather than just text, and the practical choices (and mistakes) involved in shipping this into a real production system. 19:15 - Bruno Ripa - Technical challenges of AI adoption in Healthcare Deploying AI in healthcare requires solving a shifting equation: balancing high-fidelity clinical utility against rigorous data sovereignty mandates and punishing infrastructure costs. This talk breaks down how our company navigates this fluid landscape daily. We will cover where we use AI in our stack, how localised data compliance continuously reshapes our engineering choices, and the concrete technical hurdles we encounter along the way. Rather than showcasing a finalised architecture, we will focus on the ongoing design decisions and trade-offs required to keep our product secure, reliable, and compliant, all while aggressively optimising compute and operational costs—proving that surviving the mutating challenges of healthcare AI is a continuous process of lean execution. 20:00 - Pizza & Networking Agenda --- Speakers Bruno Ripa - Dyad (Senior AI Engineer) Ellen Muller - The Guardian (Software Engineer) Hosted By Amanda Cavallaro, GDG Organizer I'm an Aikidoka, Developer Advocate, Software Developer, Google Developers Expert, Linkedin Learning Author and a Full Stack Web Development Specialist.

Make a small thing. Review it. Change it. Share it with an audience. That's a formula for software development and it's also a formula for writing a book. In this Work In Progress show, a preview of what he'll take to the Edinburgh Festival Fringe, Mark Stringer gets you started on writing a book in less than an hour. Mark Stringer is a project manager, comedian and published author. In this show, Mark talks about the writing tips and tricks that really work. He also talks about the advice that's curiously missing that he had to find out for himself.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

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!

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

These meetings will be a building block approach to learning photographic mastery over three disciplines: Mechanical Mastery (MM) - 13 weeks of the series Exposure Mastery (EM) - 26 weeks of the series Composition Mastery (CM) - A 52 week series All three series will run concurrently and will dovetail as follows: Q3/26 - MM (Iter 1), EM (Iter 1, Pt 1), CM (Iter 1, Pt1) Q4/26 - MM (Iter 2), EM (Iter 1, Pt 2), CM (Iter 1, Pt2) Q1/27 - MM (Iter 3), EM (Iter 2, Pt 1), CM (Iter 1, Pt3) Q2/27 - MM (Iter 4), EM (Iter 2, Pt 2), CM (Iter 1, Pt4) That's likely confusing, but essentially, MM offered 4 times in that period, EM offered 2 times, and CM offered 1 time. **TO BE CLEAR - THERE IS NO CHARGE FOR THESE CLASSES.** This is an aggressive series, with presentations, homework, group shoots to be added in, likely at LEAST twice a month, image critiques, and an expectation that you are willing to put in the work to elevate your photography significantly. Open to all levels and all equipment levels. Don't let hesitation about your skillset and/or gear keep you from a one-time opportunity. The group will meet every Monday, with periodic exceptions, and we will try to keep as close as possible to the original plan. Obviously, more data to come, and will be published as this is further developed, but now is the time to decide if you want to be a part of this.
