AI in Production: Vectors in the Newsroom & Healthcare Challenges
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.

Rabble - Fitness Through Games!
A Rabble session is 1 hour of fun and social team games.
Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it.
We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different.
Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before.
Come solo or bring friends! And stay at the end for the social part!
Who knew getting fit could be this fun?
**TO BOOK**:
It's essential that you book onto sessions via our website, using the link below; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals.

Silver Tuesdays Nordic Walking in Brockwell Park
Over the last nine years, Silverfit has been able to offer exercise to everyone over 50 in Brockwell Park. Together with Silverfit, I have done my best to keep the exercise fun for everyone, no matter if you are fit or not so fit, strong or not so strong, sporty or not so sporty.
And, over all, I think we have done that pretty well! We have had some glorious years, and we made many, many friends over that time.
Silverfit managed to keep it going through the good times and the hard Covid years, but unfortunately, the reality of the current economic climate is hitting Silverfit hard. Many councils and charities that have supported Silverfit over the years have stopped funding, and without funding, Silverfit just simply cannot keep going.
Recently, they have had to take the hard decision to cut quite a number of their activities, and unfortunately, Nordic Walking in Brockwell park is one of the sessions that needs to be stopped.
Yesterday afternoon was our last session for Silverfit.
But…. I aim to keep your Tuesday walk going!
So many of you love our Tuesday session, and it would just be too sad to stop completely.
I would like to keep the Silver Tuesday session going under my own company, Fit and Happy Outdoors.
Sadly, I cannot do this for free, as I do need to make a living. But in order to keep this session available for everyone, I plan to keep our Tuesday afternoon session at a highly reduced rate compared to my normal rates.
New rates for our Silver Tuesday walks:
10 sessions for £45 (my normal rate is 10 sessions for £90).
For those of you who struggle financially, I am happy to reduce this rate to £30, or even offer it for free.
I can of course only do this if enough of you pay the normal rate, and I trust you will only ask for a reduction if you really need it. As I said, I do this for my living, but I don’t want money to be the reason you miss out on the benefits of Nordic Walking and spending time with our lovely group of friends.
If you are already a member of Fit and Happy Outdoors and you pay monthly, then the Tuesday session is included in your fee. No extra payment is necessary (unless you’d like to sponsor someone who cannot pay)
How does it work?
1) Please email me at Ailien at Fitandhappyoutdoors dot com, and let me know if you agree with me sending you an invoice for the full rate, or if you need a reduced rate.
2) I will then send you an invoice with my bank details on it.
3) Once I have received your payment in my bank account, I will hand you a 10-session card at the first session I see you
4) Every time you come walking on Tuesday, I will stamp your card
5) Once you have walked 10 times, I will send you a new invoice for the next 10.
Payment: I really, really, prefer bank transfers.
If you really do not do bank transfers, then you can pay me in cash. No cheques please (I really try to avoid having to go to the bank, it is just too much hassle).
If you or a friend only comes once in a very blue moon, then they can pay £5 in cash for the session (only banknotes please. Help a girl out, I do enough weightlifting already 😊)
Are you a walk leader? You are always welcome and do not have to pay me. I am grateful for your help!
Do we still need to sign up?
1) Have your own poles? No need to sign up. But, if there is a weather warning, please check in with me as I might have to cancel and if I don’t know you are planning to come, I might not be able to tell you it’s cancelled
2) Happy to use the Meetup app, then sign up for your walk here? If you sign in, I will know you are planning to come, and it will be easy for me to let you know if I do need to cancel a session.
3) Need to borrow poles from me? Please text me ON THE DAY OF THE WALK to ask me to bring a set. My number is 078 078 3456 4. Just use normal text, no Whatsapp please, as I will probably miss your message.
Any questions? Feel free to reply to this email, or text me on the number above.

IMPORTANT
Please bear in mind this is a free of charge, self-guided trip with a hobby group. It is not organized by a business nor any entity with commercial purposes.
Any trip details, travel advice, route planning, instructions and other content in our group merely represent our shared personal knowledge, research and suggestions as outdoor enthusiasts. As this is no business, there is no "product", "service" or "package" and also no "tour guide", "operator" or "walk leader".
Each participant is responsible for their own safety. Even if some of us are very experienced walking outdoors, nobody assumes responsibility for any kind of injury, damage or loss that may happen.
Despite this, we take extreme precautions and all trips we plan are very safe, fun, highly educational and popular. Our experienced members volunteer their time and effort to shape a pleasant and quality adventure for everyone :-)
By participating you acknowledge and agree with this disclaimer.
Here are our tips on staying safe during outdoor trips:
[http://www.meetup.com/Free-Outdoor-Trips-From-London/about/](http://www.meetup.com/Free-Outdoor-Trips-From-London/about/)
TRAVEL, ACCOMMODATION, INSURANCE
Although we provide detailed suggestions, each participant is expected to arrange their own travel - this gives everyone the freedom and choice. Anyone interested in travel or outdoor insurance should also arrange this on their own. As mentioned above we always take extreme precautions, but some people may still feel safer if covered.
As most of our trips are confirmed or postponed very close to the event date - heavily depending on the weather forecasts - we advise not to buy this until the last minute. People getting tickets from the same station are encouraged to meet early on the day to benefit from discounts such as GroupSave.

6:45 Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for Safety (Hossein Kakavand, Luther Systems)
7:15 Putting Open GitOps to the test (Steve Fenton, Octopus Deploy)
7:45 Wrap up
See you there!
Cheryl (@oicheryl)
**Putting Open GitOps to the test (Steve Fenton, Octopus Deploy)**
The Open GitOps principles sound plausible, but the world is full of surprising realities. Join Steve Fenton and explore the GitOps research to see whether GitOps delivers on its promises, based on an analysis of over 600 perspectives from roles like DevOps engineers, developers, platform engineers, and cloud infrastructure engineers.
*Steve Fenton researches the socio-technical systems behind software delivery; how organizations, people, and technology actually work together (or don’t). At Octopus Deploy, he explores GitOps, Platform Engineering, Continuous Delivery, and compliance through a lens shaped by punk history, psychology, and the kind of genre fiction that asks uncomfortable questions about systems and society.*
*He’s an eight-time Microsoft MVP (DevOps), a DORA Community Guide, a CD Foundation Governing Board member, and a contributor to the CNCF Platform Engineering Community Group. He’s written books on TypeScript, Octopus Deploy, and Web Operations Monitoring, and occasionally writes horror fiction.*

**Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for Safety (Hossein Kakavand, Luther Systems)**
The more freedom we give an autonomous agent, the more it drifts into hallucinations or policy violations, yet clamping it down with prompts kills the reasoning we want. Think Brownian Motion versus a Brownian Bridge: a random walk wanders anywhere, but pin it at fixed points and it moves freely between them while always landing where it must. Deterministic checkpoints are those pins.
InsideOut applies this to infrastructure. It works with the user to shape a feature set, stack, config, Terraform and cost estimates, then deploys and manages the infrastructure in real time for monitoring, alerts and changes. Each stage must produce a structured artifact validated against fixed rules, and if a check fails only that stage repeats, catching errors before they propagate. High-stakes actions stay locked down by design: the agent can request a deploy by presenting a button, but never holds the cloud keys itself. The result is an agent that is more productive precisely because it is safely unconstrained.
*Hossein Kakavand holds a Ph.D. from Stanford University. He has been with several start up in AI, ML and Distributed Systems, with IPOs on NASDAQ and LSE. He is currently a Co-Founder of Luther Systems focused on solving the Enterprise Operations problem at scale. @HosseinKavavand*

Harness Engineering in Practice: From Requirements to Implementation
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

FREE SUNDAY HIKE - Viaduct, River, Castle & Lavender: A Darent Valley Loop
Looking for a Sunday that feels like a soft slice of summer? Join us for a beautiful 12–15 km loop through the Darent Valley, where riverside paths, rolling green fields, and blooming lavender come together in one of Kent's most charming landscapes.
This valley has been shaped by centuries of life and travel, and you feel it as soon as you step onto the trail. We'll pass beneath the towering arches of the Eynsford Viaduct, a Victorian engineering landmark that has carried trains across the valley since the 1860s. Further along, the route brushes past the historic grounds of Lullingstone Castle, a Tudor manor once visited by Henry VIII and home to the Hart Dyke family for over 500 years.
From there, the path opens into the quiet lanes of Shoreham village and the purple shimmer of the lavender fields drifting across the hillsides.
As we move through meadows, woodlands, and open countryside, the day settles into that easy summer rhythm where everything feels unhurried and lightly golden.
It's the kind of walk where the scenery does the talking: the river winding beside us, the scent of lavender in the warm air, and the countryside unfolding in soft greens and purples — a Sunday that feels sun-warmed, peaceful, and just a little bit dreamy.
We will head to a pub near the station when we finish for a pint or/and lunch.
## 📅 **Event Details**
**Meeting Point:** Eynsford Station (Start / Finish)
**Meeting Time:** 10:15 AM for 10:30 AM sharp start.
**Distance:** approx. 12 to 15 km
**Elevation:** \~300 m approx **Difficulty:**
Moderate **Pace:** Steady
**Estimated Finish:** Around 2 PM
## 🌿 **Route Highlights**
* **Eynsford Viaduct Viewpoint** — one of Kent’s most photogenic spots, especially in summer light.
* **Ancient woodland paths** around Ashen Bank, offering shade and cool forest air.
* **Shoreham Village** — postcard‑perfect with its stone bridge and riverside charm.
* **Darent Valley Path** — peaceful riverside walking with open fields and gentle breezes.
* **Shoreham Lavender Fields** — with sweeping purple rows and great photo opportunities.
* **Lullingstone Country Park** and **Castle** — meadows, woodlands, and a relaxed finish back toward Eynsford.
This is a circular route full of **colour, greenery, and soft summer atmosphere** — the kind of day that feels wrapped in the easy warmth of summer countryside.
## 🎒 **What to Bring**
* Comfortable hiking boots or sturdy shoes
* At least **2L of water**
* Packed snacks
* Sun protection (hat, sunglasses, sunscreen)
* Light layers — summer can still surprise
* Good vibes and your best Sunday‑summer energy
## 📌 **Important Notes**
* **Stay Together:** Please stay with or behind the hike leader to keep the group moving smoothly and regular catch ups.
* **Respect the Area:** Parts of the route pass through the **Kent Downs National Landscape** — please respect wildlife, fields, and local guidelines.
* **Group Rules:** Please read the “About Us” section before joining: [https://www.meetup.com/free-hiking-outdoor-fitness-and-social-activities](https://www.meetup.com/free-hiking-outdoor-fitness-and-social-activities?utm_source=copilot.com%20%22www.meetup.com%22)

Dulwich Park Nordic Walking
Ready to get outside? Our Thursday morning session in Dulwich park is back!
At this moment we can meet with up to 30 people (of more than two households) to do outdoor exercise and walks. However, i like to keep our exercise groups small, so I have set the maximum participants at 12.
For now this walk is for our experienced Nordic Walkers only, who already used to Nordic Walk with us regularly before Covid 19 kept us indoors, and who have their own Nordic Walking poles.
As this session is outdoors, we will not ask you to wear a face mask, but we do ask you to keep 2 meters apart. Some of our walkers might be immune compromised or more at risk, so please help us keep everyone safe!
Please do not come to the session and stay at home if:
- you know you have been in contact - in the last 2 weeks- with someone with symptoms of possible Covid, or if you have been in contact with someone who tested positive.
- you have any of the following symptoms: (new) Loss of smell/taste, Persistent cough, Fatigue, Loss of appetite, Skin rash, Hives, Fever, Severe muscle pain, Shortness of breath, Diarrhoea, Delirium, Abdominal pain, Chest pain, Hoarse voice, Eye soreness, Sore or painful throat, Nausea or vomiting, Headache, Dizziness or light headedness
We meet by the cafe in the middle of the park.
Session Price: £10 per session, £89 for a 10-session card or £70 unlimited sessions per month. Session cards and pay Monthly can be used in any of our outdoor walks or indoor Zoom classes sessions (except for the Parkinson's sessions).
Pay What Works:
The price shown above is the “true” value of the session that best reflects the work I put into preparing and leading your session. However, I understand that not everyone can afford to pay full price, and I don’t want that to stop you from joining us.
In an effort to find a balance between more financial accessibility and sustainable pricing, I now offer a “Pay What Works” model. This allows for financial flexibility while still valuing and respecting the work and energy I provide in creating and delivering these classes.
Then send an email to ailien@fitandhappyoutdoors.com with the heading “INVOICE please”- followed by “FAHO 1” to pay full price as quoted below, “FAHO 2”, for 20% off, or “FAHO 3” for 50% off.
Pllease do tell me if you want to pay for 10 sessions, or if you’d like to pay monthly.
I prefer payment by bank transfer, but if that is not possible you could pay in cash. No cheques please, the queues by the banks are just too long.
We walk in all safe weather conditions – if a walk is cancelled, we will contact you to let you know. Please check for text messages or Meetup messages before leaving home!

Short North Street Skate | Weekly Rollout
Short North Street Skates return Saturday, April 4 and we’re excited to get back rolling together.
These weekly rollouts are a chance to move through the city as a group, build community, and create more visibility for skating and small-wheeled movement in Columbus.
Details:
Meet: 1160 N High St
9:30 AM meet
10:00 AM rollout
All wheels welcome
We’ll be skating through the Short North and surrounding areas at a steady, social pace. Routes will use a mix of streets and bike lanes, so comfort navigating the city is helpful, but you don’t need to be an expert.
If you’ve been meaning to come out, this is a great place to start.
Come solo or bring a friend!
COUNT RMH Housewarmer Volunteering (Ronald McDonald House)
Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process.
Fast track
• Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell).
• Show up and try it out.
• Complete application, etc. later.
Normal process
• Complete an online application (http://rmhc-centralohio.org/volunteer/).
• Attend orientation in advance.
• At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility.
• Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM.
• Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895).
The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014.
Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

Pop-up Book Club 5: Rabbit, Run by John Updike
Let’s meet and discuss John Updike's Rabbit, Run, the first in his series of four novels following the life, hopes, and disappointments of former local basketball star, Harry "Rabbit" Angstrom, as he fitfully confronts and evades adulthood.
Stop Guessing: How to Measure and Improve LLM Outputs
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.
