AI assistants are getting more capable. The question is how we build effective workflows around them. At DevDay London, [Lucy Joyce](https://www.linkedin.com/in/lucy-joyce-597485166/), [Ash Shakrani](https://www.linkedin.com/in/ash-shakrani/) and [Arun Kurian](https://www.linkedin.com/in/arun-mathew-kurian-39b8aa5a/) will explore harness engineering through the lens of a payment integration. From requirements and design through to implementation, they’ll demonstrate why context alone isn’t enough for successful AI-assisted development. Drawing on real-world experience, they’ll show how engineering harnesses, reusable context, standards, and validation workflows help teams move beyond experimentation and build reliable, scalable AI-assisted development practices. **This session will unpack:** 🎯 Why “more context” isn’t the answer on its own 🎯 What engineering harnesses are and how they create reliable feedback loops 🎯 How standards, workflows, and validation reduce AI-generated rework and technical debt 🎯 Practical techniques teams can adopt immediately to improve AI outcomes 🗓️ **Save the Date:** 2nd July, 2026 📍 **Location:** Sahaj Software, 1 Quality Court, London, WC2A 1HR 🕕 **Time:** 6:00 PM – 8:00 PM (BST) The evening will feature: 🎤 **One engaging talk** with Q&A 🤝 **Plenty of time for networking** over free pizza and non-alcoholic drinks Don’t miss this chance to learn, connect, and share with fellow tech enthusiasts. 👉 Please click the link below to register. https://sahaj.ai/events/harness-engineering-in-practice-from-requirements-to-implementation/

We’re all about helping people smash their goals, stay accountable, and build cool things. *Spaces are limited based on venue capacity, so please RSVP if you plan on coming. See you on Saturday!*

Basic Ideas: 🌞 📚☕ Any books sitting there collecting dust? Some holiday gifts? Or it’s a book that has changed your life that you want to share? Feel free to bring book(s) to discuss or swap, we usually have more books than people in the end, so feel free to pop along just to have a chat as well. Aiming for every 4 weeks book swap meetup. Note: The event is free to attend, so the only cost for you will only be buying a drink at the location, so coffee/tea/beer etc.

In this event, we will discuss about a science or philosophy book chosen by London Science and Philosophy Book Club. The attendees will be divided into groups and each of them will focus on a chapter in the book. This month we will discuss about a fascinating book called Supersense: From Superstition to Religion by Bruce Hood. If you haven't read the book, it's no problem. I will bring you up to speed with the discussion materials. We will meet in a nice lounge area at 6 p.m for introductions. Please come on time so you will not miss out on valuable discussion midway. If you end up in the waitlist, feel free to show up. Book Description: Why is it that Tony Blair always wore the same pair of shoes when answering Prime Minister's Questions? That John McEnroe notoriously refused to step on the white lines of a tennis court between points? And that President-elect Barack Obama played a game of basketball the morning of his victory in the Iowa primary, and continued the tradition the day of every following primary? Superstitious habits are common. Do you ever cross your fingers, knock on wood, avoid walking under ladders, or step around black cats? Sentimental value often supersedes material worth. If someone offered to replace your childhood teddy bear or wedding ring with a brand new, exact replica, would you do it? How about £20 for trying on a jumper owned by Fred West? Where do such feelings come from and why do most of us have them? Humans are born with brains designed to make sense of the world and that need for an explanation can lead to beliefs that go beyond reason. To be true they would have to be supernatural. With scientific education we learn that such beliefs are irrational but at an intuitive level they can be resistant to reason or lie dormant in otherwise sensible adults. It now seems unlikely that any effort to get rid of supernatural beliefs or superstitious behaviours will be completely successful. This is not all bad news - such beliefs are a useful glue that binds us together as a society. Combining brilliant insight with witty example Hood weaves a page-turning account of our 'supersense' that navigates a path through brain science, child development, popular culture, mental illness and the paranormal. After reading SuperSense, you will realize why you are not as reasonable as you might like to think - and why that might be no bad thing. Agenda: 6 p.m to 7 p.m: Introduction and Socializing 7 p.m to 9:30 p.m: Book Discussion 9:30 p.m to late night: Drinks, Dinner or Feel free to go home

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: Completely Mechanical (CM) - A 13-week series Completely Exposed (CE) - A 26-week series Completely Composed (CC) - A 52-week series All three series will run concurrently and will dovetail as follows: Q3/26 - CM (Iter 1), CE (Iter 1, Pt 1), CC (Iter 1, Pt1) Q4/26 - CM (Iter 2), CE (Iter 1, Pt 2), CC (Iter 1, Pt2) Q1/27 - CM (Iter 3), CE (Iter 2, Pt 1), CC (Iter 1, Pt3) Q2/27 - CM (Iter 4), CE (Iter 2, Pt 2), CC (Iter 1, Pt4) That's likely confusing, but essentially, CM offered 4 times in that period, CE offered 2 times, and CC 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 Tuesday, with periodic exceptions, and we will try to keep as close as possible to the original plan. Obviously, more data is coming 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.
