OCaml Programming

uSwitch is located on the first floor of the ZPG building at 5 Copper Row, London, SE1 2LH, London (Click on the map for directions) What 3 words location: [https://what3words.com/puts.sudden.else](https://what3words.com/puts.sudden.else) The Clojure dojo is a collaborative way to learn Clojure/ClojureScript through practice. The aim is to learn a little more than before you started. This event is for those new to coding through to more experienced developers. We organise into small groups (2-4) people and write code to solve challenges great and small, chosen by those at the event. We aim to ensure someone in your group has some Clojure experience, so you shouldn't feel lost (well no more than all developers do when Stack Overflow is broken). Example challenges for the coding dojo are listed on this website: http://www.londonclojurians.org/code-dojo/ Various past exercises have been loaded to [https://github.com/ldnclj](https://github.com/ldnclj/lisp1.5/blob/master/src/lisp1/5.clj) # Approximate schedule: 18:40 Doors open and start collecting suggestions 18.45 Pizza should have arrived 19:00 Quick intros and vote on suggestions 19:15 Break out into groups and start practising 20:45 Gather together for a quick show and tell # What should I bring? We organise into small groups, so if you have a laptop with a working Clojure environment please bring it along (there are lots of online Clojure environments, so you can just use your browser too). # How do I get in to the building? At the glass doors press the buzzer to inform the security guard you are here. Say you are here for the event on the first floor. Is there way to talk with the Clojure community? Why yes. The Clojurians Slack channel is full of friendly people who love to try and help. People based in London are often in the #clojure-uk channel. Sign up for a free account to the Clojurians Slack community via http://clojurians.net/ What is Clojure? Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

Behind every put-together facade we know there’s a weirdo waiting to go unfiltered! We are now running this club in two locations. Ready to join the fun and unleash your creative side? We will always start with warm up games and fun ice-breakers, making sure everyone feels welcomed and relaxed. During this section we do a short 5-rhythms movement meditation practice to release tension in the body. We then move on to fun improv exercises and games. We ease into this section starting from shorter, straightforward improv games and activities to slightly longer and more dynamic once 😊 Who attends our club? The simple answer: everyone (above 18+) We’ve welcomed people from every walk of life — from actors and artists to consultants, tech innovators, IT specialists, designers, entrepreneurs, students, job-seekers, and retirees. No matter your background or experience, come try the class and see if it’s a good fit for you! www.actorverse.co.uk

Toastmasters Polish Your Polish zaprasza na wyjątkowe spotkanie pod hasłem: “The Grand Theatre of Attention” „Od Szekspira do TikToka: Wielki Teatr Atencji” Przez wieki chodziliśmy do teatru, by celebrować chwilę. Potem kino nauczyło nas kochać perfekcyjne cięcia. Dziś naszą sceną jest 15-sekundowy Reels, a reżyserem — algorytm Netflixa. Czy w dobie niekończącego się scrollowania wciąż potrafimy słuchać historii, które trwają dłużej niż minuta? Czy teatr i kino nadal są awangardą rozrywki, czy może zostały wyparte przez kulturę natychmiastowej uwagi? Na najbliższym spotkaniu Toastmasters będziemy mówić o sile opowieści, uwadze, współczesnej komunikacji i o tym, jak zmienia się sposób, w jaki odbieramy świat. 🎬 Kurtyna w górę! 📅 Data: Wtorek 12 maja 🕖 Godzina: 19:15 📍 Miejsce: Ognisko Polskie Spotkanie odbędzie się w języku angielskim. Serdecznie zapraszamy Do zobaczenia 🎤 Jeśli jednak wolisz uczestniczyć online, to będzie też możliwość uczestniczenia przez Google Meet https://meet.google.com/sxz-jkqp-ihp Więcej informacji o klubie na naszej stronie: http://www.polishyourpolish.org.uk/ www.facebook.com/pyplondon www.instagram.com/polishyourpolishlondon www.linkedin.com/company/polish-your-polish-toastmasters Strona Ogniska Polskiego: www.ogniskopolskie.org.uk

The Square is a 2017 satirical black comedy film written and directed by Ruben Östlund. The film stars Claes Bang, Elisabeth Moss, Dominic West and Terry Notary. A Swedish production with co-production support from Germany, France and Denmark, it was shot in Gothenburg, Stockholm and Berlin. The story was partly inspired by an installation Östlund and producer Kalle Boman had made. Östlund was also inspired by a notorious incident involving Oleg Kulik and cast Notary in a parody, drawing on Notary's experience imitating apes. The film was entered into the 2017 Cannes Film Festival, where it received positive reviews and won the Palme d'Or. It was subsequently selected for the 2017 Toronto International Film Festival. It went on to win six European Film Awards, including Best Film; two Guldbagge Awards, including Best Director; and other honours. It was nominated for the Academy Award for Best Foreign Language Film at the 90th Academy Awards. Please note we will not be showing the film at the meeting. Make sure you watch the film before you attend and then come and join in with the conversation. It’s just a discussion. It’s not a screening. We will be meeting in The Ludski Bar in the Rio Cinema.

Hi guys! welcome! hope you’re all well. Join us for our first walk & talk event in camden. We’ll be meeting on the 14th @10:00AM at King’s Cross Station (exact meetup location will be disclosed the day before on our whatsapp groupchat). It’ll be a short and relaxed walk around king’s cross. We’ll be walking through granary square, exploring coal drops yard and then walking to gasholders park before making our way back to king’s cross and to a little hidden park! The walk will probably take about 30mins depending on whether we stop for coffee/snacks or let the kiddos explore for a little bit. The route is family and buggy friendly with lots of opportunities for drink/snack stops and there’s access to toilets and baby change facilities. Join our WhatsApp community to stay in the loop with all of our events and updates: https://chat.whatsapp.com/CWefJ5Kage1L0W2Sco6eOu Looking forward to seeing you there!

🎉 Come along to the London Scala Talks! 🎉 In this event you'll hear from Caroline Morton and Katrina Petrevice. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Katrina Petrevice: Caching in Scala using Ref 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan and vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ Caroline Morton: Accidental Functional Programming in Rust (From an Epidemiologist's Perspective) 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event may have a live stream** Watch this space for more details. **🗣️ Katrina Petrevice: Caching in Scala using Ref** Caching in memory is often one of the first strategies used to improve system performances. However, implementing caching in a purely functional way introduces unique challenges, specifically around state management and testability. In this talk, we will look at how to utilise functional programming principles with [Ref](https://typelevel.org/cats-effect/docs/std/ref), while maintaining clarity and composability. We will also deep dive into some common pitfalls and look into practical ways to test Ref effectively. ⭐ Katrina Petrevice ⭐ Katrina comes from a non–computer science background and was first introduced to Scala while working at JPMorgan. She credits much of her Scala knowledge to hands-on experience within her team, where she works on building and maintaining data pipelines and managing data systems. Since then, she has developed a strong interest in functional programming and now co-leads the Functional Programming Group at JPMorgan, where she helps share knowledge and foster a community around these ideas. **🗣️ Caroline Morton: Accidental Functional Programming in Rust (From an Epidemiologist's Perspective)** I don't have a background in functional programming - and I never set out to write it. But somewhere between writing trait-based epidemiological pipelines, composing data transformations, and leaning hard on Result, enums, and pattern matching, I started hearing from others: “That's pretty functional.” In this talk, I'll explore what it means to write “functional-ish” Rust as someone solving real-world scientific problems. I'll walk through the patterns I reach for - like chaining iterators, avoiding shared state, and embracing expressive types - and reflect on which functional programming ideas emerge naturally in Rust, even if you're not trying. I'll also share how designing for epidemiologists - most of whom are used to chaining functions in Python (like Pandas) or R - has pushed me toward creating ergonomic Rust APIs with Python and R bindings. These tools aim to feel familiar to scientists while leveraging Rust's power and safety under the hood. This is a talk for functional programmers curious about Rust, and for Rustaceans wondering if they've been functional all along. No formal theory required - just real code, real use cases, and a pragmatic perspective from someone building public health tools in Rust. ⭐ Caroline Morton ⭐ Dr. Caroline Morton is a medical doctor, epidemiologist, software engineer, and PhD candidate specialising in synthetic data, epidemiology, and Rust. With 60 peer-reviewed papers and two books on software, she combines deep technical expertise with a commitment to improving scientific workflows. Caroline co-founded the first [Women in Rust](https://www.meetup.com/women-in-rust/) group, fostering diversity and encouraging more women to explore opportunities in systems programming. She leads an open-source project improving codelist management in epidemiology using Rust, creating efficient, reliable tools for health data research. Her PhD focuses on synthetic data methods for epidemiology, particularly using Rust to generate large, realistic datasets. A strong advocate for open science and reproducibility, she contributes extensively to improving software practices through publications, workshops, and open-source projects. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

We're delighted to announce an exciting LSCC event on Wednesday 13th May, in partnership with our friends at Zopa Bank! Join us at the Zopa Canary Wharf office in London for this session and get the chance to flex your architectural design muscles! "So how are we supposed to get great architects, if they only get the chance to architect fewer than a half-dozen times in their career?" — Ted Neward. This quote highlights the need for practice, which is what our LSCC architecture katas provide: a safe, repeatable way to hone your software architecture design skills by simulating architectural challenges. **What's the format?** You'll be split into groups and have a business problem to solve. You'll be tasked with designing a technical architecture to meet that problem context. As with real-life you'll have to manage various trade-offs in your design and interact with a Product Owner to clarify your questions. At the end of the task each team will showcase their architecture and technology choices back to the wider group as part of a group discussion. Whether you're a seasoned coder, software architect or new to the scene, you're invited to share insights, discuss best practices, and learn from fellow participants. No prior session attendance or architecture knowledge is required – just bring your enthusiasm. No laptop is required for this session, we'll provide each group with paper, pens and sticky notes to support the activity. Thank you to the Codurance team that will run the event at Zopa Bank's office. Find out more at https://www.codurance.com/ Food and drinks will be provided with vegetarian, vegan and non-alcoholic options available - thanks to Zopa Bank for sponsoring refreshments and hosting in their great office. **About Zopa** Founded in 2020 with a full banking licence and backed by some of Silicon Valley’s most iconic investors, digital bank Zopa is building the Home of Money.

Reportage photography or visual narrative photography is the art of telling the story of an event or location through photographs. It is based on photojournalism and when carried out properly, reportage photography will provide a comprehensive collection of photographs that will form a story of the subject. In this edition of this storytelling workshop we will choose from a selection of topics occurring around Chinatown in order to create a collection of photo stories. It is going to be challenging but also full of discovery. You will learn how to report and tell your story from beginning to end and then given a brief and a series of exercises to help you tell your story. WHAT YOU WILL LEARN * How to create a visual narrative * What makes a good story and how to show it visually * How to tell a story with a series of photographic images * Improve your composition skills to create impactful images EXPERIENCE LEVEL * Beginner/Refresher EQUIPMENT * Any camera including mobile phone * Any lens CONTACT * Alex 07956 264049 VENICE PHOTOGRAPHY WEEKEND - Oct 2026 [https://www.meetup.com/londonphotographic/events/313109100/](https://www.meetup.com/londonphotographic/events/313109100/) UPCOMING EVENTS [www.meetup.com/londonphotographic/events](http://www.meetup.com/londonphotographic/events)

MCP is changing how developers build with AI, but we're just scratching the surface. Join us for an evening of talks that go beyond retrieval to explore what's actually possible when you give agents real tools, real constraints and real APIs. **Agenda** ​6:00 PM - Doors open, registration and networking ​6:10 PM - Welcome (Upsun & Cloudflare) ​6:20 PM - MCP: Context is Everything! - Carly Richmond, Elastic ​6:45 PM - Sandboxes: how to limit agents so we can use them more - Patrick Dawkins, Upsun ​7:00 PM - Break (Food & Drinks) ​7:30 PM - Cooking with MCP in VS Code - Liam Hampton, Microsoft ​7:55 PM - Efficient tools with MCP code mode - Confidence Okoghenun, Cloudflare ​8:15 PM - Open networking and drinks ​9:00 PM - Close 🗣️ ​**Talks** ​**MCP: Context is Everything! - Carly Richmond (Developer Advocate Lead, Elastic)** ​MCP is a powerful tool for giving LLMs capabilities to not just retrieve information, but to automate key actions based on relevant data. Let’s see how it can be used for retrieving relevant context and other activities such as observability. ​**Efficient tools with MCP code mode - Confidence Okoghenun (Senior Developer Advocate, Cloudflare)** ​Traditional MCP approaches choke on context windows: Cloudflare's 2,500+ endpoint API would require 1.17 million tokens. Code Mode flips the script by having LLMs write code against typed APIs instead of making direct tool calls, achieving 99.9% token reduction. Come learn how code mode works and how to optimize your MCP tools with it. ​**Sandboxes: how to limit agents so we can use them more - Patrick Dawkins (Principal Engineer, Upsun)** ​We want our agents to run longer and use more tools, but we're hampered by constant prompts for approval. Sandboxes are the practical middle ground: isolate the agent so you can stop watching every command and let it work. This talk covers what "sandbox" means, who provides them today and the Linux primitives that let you build one yourself. ​**Cooking with MCP in VS Code - Liam Hampton (Senior Cloud Advocate, Microsoft)** ​In this session Liam will show you how VS Code is fully supporting the MCP spec, from MCP Apps to sandboxing and elicitations. 📅 **Date and Time:** Thursday, May 14, from 6:00-9:00 PM 📍 **Location:** Cloudflare Address: 6th Floor, County Hall/The, Riverside Building, Belvedere Rd, London SE1 7PB, UK 👉 You can also register here: https://luma.com/eb8j6lhu ⚠️ Please make sure you provided your full name (no nicknames or abbreviations will be allowed) and to bring your ID card as it will be mandatory to show it upon check-in to security. Entry will be first come, first served. We recommend arriving early to make sure you get in. **⚡️ Interested in giving a talk? ⚡️** Have you ever considered presenting on your Elastic use case? We welcome 5-10 minute lightning talks, 45-minute deep dives, and everything in between. If you're interested, please submit via our [CFP](https://sessionize.com/elastic-meetups/) or send us an email at [meetups@elastic.co.](http://meetups@elastic.co./)

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** TBD **YouTube Link** TBD

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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.

We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level. This program is less competitive, no champions crowned, no league standings just dedicated tennis partners who want to meet up with you on the courts. Players will meet up to play a tennis match or just to hit around. Just go through the [Join Page](https://www.tenniscolumbus.com/partner-program) to enter this program.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

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!

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: This month John Lairson will share a notebook describing the Alpaca (Paper) Trading API and discuss different algorithms for evaluating stock trades. We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com
