*Please scroll to end for important meeting point details* Bank Holiday Riverside Walk! Join us for a scenic walk taking in both sides of the river & Old Rotherhithe village. We'll visit three interesting historic pubs (all with outside seating), blending a walk with a pub crawl-pubs are towards the end, near Rotherhithe Overground station, with easy connections to Jubilee, District, H&C & Elizabeth lines. *Meetup Point Details:* Outside London Bridge Station (Jubilee & Northern lines), near the escalator leading up to The Shard, opposite Guy's Hospital

*this event is advertised elsewhere so there will be more people coming than stated* **✨ Welcome to Conundrum Corner at The Union Jack pub, Southwark! ✨** Step inside and join a gathering *of* open minds and kind hearts. Whether you bring a conundrum of your own that you are experiencing or simply your listening ear, you’ll find a welcoming space to share, reflect, and explore life’s tricky questions together. 🌿 **What to expect:** * You’re invited to share a conundrum, dilemma or question that you yourself are experiencing. * We’ll vote on three intriguing ones to explore more deeply. * With a few extra details in hand, we’ll break into small groups for thoughtful discussion. * Then, we’ll come together as one big group to share insights, perspectives, and perhaps even some fresh solutions. The atmosphere is **analytical yet empathetic, thoughtful yet light-hearted**, and always non-judgmental. Whether your conundrum is personal, professional, or just a head-scratcher, we’re here to help unravel it together. 💸 There’s no set fee to attend, but we do ask for donations on the night to cover costs - which are warmly appreciated! 🍷 Please also support our lovely hosts, Jade and co., by buying yourself a drink at the bar (and food’s available if you fancy a bite). 💡 **What’s a conundrum, you ask?** A conundrum is any dilemma, crossroads, or confusion in your life—big or small. It could be a **"chicken and egg"** situation, a **"catch-22"**, or a **"have your cake and eat it"** kind of puzzle. Sometimes, life just throws us complex, messy questions—and that’s what we’re here to navigate together. Once our deep discussions wind down, we’ll slip into **pub mode**—a chance to relax, connect, and continue chatting with newfound friends. **🛡️ Code of Conduct - *please note*** Conundrum Corner is committed to providing a safe and respectful environment for all attendees. Any abuse, harassment, or inappropriate behaviour towards other attendees, whether during the event or in any contact related to the event afterwards, will result in permanent removal from the Meetup group and exclusion from future events. Come along for an evening of intriguing conversations, fresh perspectives, and a touch of serendipity. Looking forward to seeing you there! Helena x

Hi friends, Off to a great start! Our first few events made one thing clear, we got together because we all agree it’s surprisingly hard to meet others in our field outside of work or a commercial conference. As a smaller group, we make meaningful connections with like-minded actuaries and quants. Lifelong friendships are forged along the way! Whether you're a veteran, a rising star, or simply new in town and want to expand your social circle, get into the insurance and banking space, or see a friend you know, this is the place to be! No guest speakers nor rigid agenda, just a casual meetup and lots of fun conversation! 🥳 We're also on Luma, so please follow us there too! https://luma.com/friendly-actuaries-quants See you soon! NOTE: Please remember to bring your ID with you, as all guests must be of legal age to enter the venue. **About Us** We're a sister group of [The Friendly Data Meetup London](https://www.meetup.com/the-friendly-data-meetup/?eventOrigin=home_groups_you_organize), a bootstrapped 2000+ person group (and still maintains that small cozy vibe!). This one is focused on actuaries and quants :D 🤗 Welcome actuaries, quants and friends! Sometimes, it can be difficult to make friends within the field, and that's what we're all about! We're a group of like minded individuals who understand the highs and lows of working in finance and insurance. ✅ Our primary goal is to have higher quality conversations that are more meaningful, with smaller groups so that we get to spend more attention on each individual. 💯 If you're already reading this, you're definitely welcome! We welcome everyone, whether you're already in the field, looking to get started or just curious! 🗨️ Bring your friends, bring your plus ones, we're all just here to have a good laugh and a good chat about the world, even if it isn't always about our work. **Our values:** 📖 Openness - We welcome everyone 🤝 Trust - Build long-lasting friendships together 💝 Care - Be kind to others and help each other out **Who it's for:** \- Life Actuaries \- Non\-Life Actuaries \- Health Actuaries \- Pensions Actuaries \- Reinsurance Actuaries \- Quantitative Analysts \- Quantitative Traders \- Investment Bankers \- Portfolio Managers \- Financial Engineers \- Entrepreneurs\, Contractors \- Anyone who works with Insurance\, Pensions\, Hedge Funds\, Investment Banks\, Asset Managers etc\. \- Anyone looking to get into the space \- Friends **How to Make the Most of the Meetup** The Friendly Meetup for Actuaries and Quants has one simple purpose: meaningful connections. We're not just a community of people, we're friends who get invested in each others lives. We check in on our friends regularly, and personally. So come and join us, more than just once or twice! **Code of Conduct:** The Friendly Meetup welcomes all genders, nationalities, ethnicities, backgrounds, identities etc. There is a strict no discrimination policy in adherence to our code of conduct and our guiding principles. We maintain a zero-tolerance policy for hateful or antisocial behaviour. In short, be kind to others. Do not insult or put down others. Behave professionally, don't make others uncomfortable. Remember that harassment and sexist, racist, or exclusionary jokes are not appropriate for The Friendly Meetup.

**Venue:** Riverbank House, 2 Swan Ln, London EC4R 3AD **Please note:** 1\. 🚨🚨🚨 A valid photo ID is required by building security\. 🚨🚨🚨 2\. This event follows the [NumFOCUS Code of Conduct](https://numfocus.org/code-of-conduct). Please familiarise yourself with it before attending. If your RSVP status says "You're going" you will be able to get in. No need to show your RSVP confirmation when signing in. If you can no longer make it, please unRSVP as soon as possible. **Code of Conduct:** This event follows the NumFOCUS Code of Conduct. Please get in touch with the organisers with any questions or concerns. As always, there will be free food and drinks, generously provided by our host, Man Group. **Main Talks** 1. [Robin Linacre](https://www.linkedin.com/in/robinlinacre/) - **Rapid deduplication and fuzzy matching of large datasets using Splink** This talk introduces Splink, a free and open source Python library for probabilistic record linkage and deduplication at scale. I’ll explain the core ideas behind the approach, show how it can be used in practice, and reflect on the opportunities of building open source tools from within the public sector. Data deduplication is a common data quality challenge: it arises whenever multiple records are collected about the same person, organisation, or entity without a shared unique identifier. This talk will introduce the core ideas behind probabilistic record linkage and show how Splink, a free and open source Python library developed at the UK Ministry of Justice, can be used to link and deduplicate large datasets quickly and accurately. I’ll cover the practical steps involved in training linkage models, using unsupervised learning, improving performance and accuracy, and visualising results and diagnostics. I’ll also touch on what it has been like to build and maintain open source tooling from within the UK public sector, and the opportunities this creates for solving problems at citizen scale. The talk is aimed at people with basic experience working with tabular data in Python, and assumes no prior knowledge of record linkage. 2. [Filip Makraduli](https://www.linkedin.com/in/filipmakraduli/) - **Small Model Inference Infrastructure: Lessons Beyond vLLM** Embedding models are evolving rapidly, from dense-only architectures, to hybrid dense+sparse (BGE-M3), multi-vector late interaction (ColBERT), and vision-language models (ColQwen2, SigLIP). Yet while LLM serving infrastructure is well-established (vLLM, SGLang), small model deployment still relies on inefficient single-model containers or custom-built systems. Production teams face a dilemma: deploy dozens of single-model containers with 5-10% GPU utilization, or invest months building complex multi-model infrastructure. This talk explains some of the key concepts of embedding inference and how it is different to LLM inference. 3. [Ian Ozsvald](https://www.linkedin.com/in/ianozsvald/) - **Build your own LLM, Live, with MicroGPT** Andrej Karpathy's MicroGPT is a single file no dependency mini GPT, you can run it live with me. We'll talk about how GPT works, we'll look at the code, we'll reflect on the Torch-based nanoGPT "big brother" and you'll end the talk with stronger intuitions about how our next best token guessing overlords are working. Plus you'll have a mini GPT running on your laptop in 200 lines of Python. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** * Doors open at **6.30 pm** (get there early as you'll need to sign in with building security). * Talks start at **7:00 pm**, with drinks afterwards from **9:00 pm** at The Banker (EC4). We have reduced capacity for this event, but there will be plenty of people to discuss data science questions with. Please unRSVP in good time if you realise you can't make it. We're limited by building security on the number of attendees, so please free up your place for your fellow community members. If you want me to trim lightning talks down to two or shorten any abstracts, say which ones.

Apologies for any inconvenience.** This event takes place on Tuesday as Monday is a public holiday in the UK This talk will focus on a single question: ‘Where do you belong?’ The idea of ‘home’ reflects one of the deepest and most universal of human experiences. ‘Homes’ may be physical, emotional, intellectual or cultural – they reflect aspects of life with which we identify, where we feel comfortable (or challenged) and where we belong. They are a defiant response to our awareness of the vastness of space. From Diogenes and Buddha to Nietzsche and Heidegger, we’ll be looking at the experience of belonging, and exploring ways in which it shapes our thinking about the nature of self, ethics and politics. Over the last 50 years, **Mel Thompson** has written more than 40 books on philosophy and religion and is probably best known for the philosophy titles in the long-running ‘Teach Yourself’ series.

Lets have a get together mid week.... We used to have a successful meetup here on Tuesdays so I am going to give it another whirl and see how it goes As you know this is a Wetherspoons so good prices!!!! Conveniently situated 2 mins walk from Elizabeth line, Hammersmith & City, Metropolitan, Circle Line and Thameslink Come along and joins us, as I say the more the merrier.. PLEASE CAN YOU SIGN UP IF ATTENDING

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
