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 .

Approx 6 miles, passing through the grounds of Knebworth House. Starting point is from a small car park on Park Lane, Knebworth: https://maps.app.goo.gl/LzgzGBPKvGJ6wfdq6 What3words ///image.cage.minute There's not a lot of space to park so we may need to double park and some may have to try and park on the road. The Lytton Arms is a good real ale pub nearby for those who fancy a drink or bite to eat. Bring water and snacks. Wear proper walking attire. Decent pace, not military march but not sauntering either. Walk and chat pace. All ages and abilities welcome. Come and enjoy nature, led by Nigel and Amy. 
Please note that this walk is not led by a qualified leader and, as such, is not covered by insurance. Be sure to wear suitable boots and clothing. 
The organiser cannot be held responsible for any injuries, however caused. Members are expected to take responsibility for their own preparation and safety, including adequate fluids, weather protection and a snack. No public toilets on route.

Unless otherwise announced this is an in-person social gathering for Smalltalkers to get together and talk about Smalltalk (the Programming Language!). Everyone is welcome from the grizzled and experienced to the merely curious.

🎉 Come along to the London Scala Talks! 🎉 In this event you'll hear from Tomasz Godzik and Noel Welsh. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:40pm - 🗣️ Tomasz Godzik: Metals Version 2! 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan, vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ Noel Welsh: Code as Communication: Lessons from Crashing Production 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 has a live stream** Watch this space for more details. **🗣️ Tomasz Godzik: Metals Version 2!** Metals is the Scala Language Server, providing IDE features within editors such as Visual Studio Code, Cursor, Zed, and Helix. This makes it essential for anyone looking to use new agentic tools. Many companies are now utilizing LLM trends to boost developer performance, but a major challenge has has been that Metals becomes less efficient as codebases scale - a common issue in large organizations. Metals 2 is a new indexing and compilation approach, designed to make indexing as fast as possible and ensure the codebase remains functional even if parts of the project fail to compile. Applying this to both Scala and Java code, Metals 2 aims to become the premier JVM language server. Let’s explore how this can enhance your workflow. ⭐ Tomasz Godzik ⭐ Scala tooling engineer aiming to solve large problems with elegant solutions **🗣️ Noel Welsh: Code as Communication: Lessons from Crashing Production** Code is a form of communication: with the computer but also with other developers, be they human or otherwise. In this talk I'll discuss some aspects of communication in code. We'll look at what can go wrong, the problems it can cause (including embarrassing examples from my own experience!), and ways we can improve things. ⭐ Noel Welsh ⭐ Noel is a developer, teacher, and author. He's worked with companies big and small across Europe, the USA, and even once in Africa. He's the organizer of ScalaBridge London, a diversity focused group helping people get better at Scala. When he's not programming Scala he is probably writing about it. His next book, Functional Programming Strategies, is out soon! ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

***P.S: [Luma](https://luma.com/4hs6hs36) Registration is Required for this event.*** **Theme:** ***Agentic Coding 🤝 [ACP](https://agentclientprotocol.com/)* (Agent Client Protocol)** **💻 Coding Agents and ACP with JetBrains** 💎 State of [ACP ](https://www.jetbrains.com/)from **[Jetbrains](https://www.jetbrains.com/) & [Zed Industries](https://zed.dev/)** 🎙️Panel with **[Jetbrains](https://www.jetbrains.com/) [Zed Industries](https://zed.dev/) [Mistral AI](https://mistral.ai/) & [Vibe Kanban](https://vibekanban.com/)** **Agent Client Protocol ([ACP](https://agentclientprotocol.com/)) and the Future of Interoperable Coding Agents** Coding agents are part of everyday development workflows. Whether you are using an IDE or working in the CLI, coding agents are helping developers write, refactor, test, and debug code. But today’s ecosystem is fragmented, we have so many coding agents Claude Code. Codex, Gemini CLI and many others. Every editor, every tool, and every agent often speaks its own language and has own harness. Not single coding harness will solve you all needs and you should be able to switch or have a choice to use different harnesss What if you could use **any coding agent** inside **the editor you love**? That is exactly what the **Agent Client Protocol ([ACP](https://agentclientprotocol.com/))** enables. ACP is an open protocol that standardizes communication created by Zed Industries, between code editors and coding agents. It works for both local and remote scenarios. Think of it as the LSP for coding agents. Just as the Language Server Protocol unified language tooling across editors, ACP aims to unify how editors interact with intelligent coding agents. **Sponsors** Big Thanks to our Sponsor **[Jetbrains](https://www.jetbrains.com/)** And thanks to **[Tessl](https://tessl.io/)** for hosting the venue. **What You Will Learn** In this session we explore how ACP is shaping the next generation of coding agent interoperability. • What the Agent Client Protocol is and why it matters • Current State of ACP and Future • How ACP standardizes communication between IDEs and coding agents • How to use ACP inside your favourite IDE • How to build an ACP client • Practical considerations for using ACP effectively • The future of coding agent interoperability If you are building or using coding agents, this session will give you both conceptual clarity and practical direction. 🎤 **Talks** **Talk 1: State of ACP and Future (45min)** Speakers: **[Sergey Ignatov](https://www.linkedin.com/in/sergey-ignatov/) Director of Engineering, JetBrains** \*\*[Ben Brandt ](https://www.linkedin.com/in/benjaminbrandt/)\*\*Zed Industries **Description :** This talk with In this session Sergey and Ben will introduce ACP and share Future plans of Agent Client Protocol from the company behind the ACP (Zed Industries) and Jetbrains ACP: \- Overview \- State of ACP \- Ecosystem around it \- Future \- Recent Implications: OpenClaw\, Custom Agents with Agent Frameworks like LangGraph\, LlamaIndex and Cursor Wrapper etc 🎙️ **Panel and Q&A 25 min** **Topic:** Agentic Coding, ACP anf Future Panelist: **[Sergey Ignatov](https://www.linkedin.com/in/sergey-ignatov/) Director of Engineering, JetBrains** \*\*[Ben Brandt ](https://www.linkedin.com/in/benjaminbrandt/)\*\*Zed Industries \*\*[Clément Drouin ](https://www.linkedin.com/in/cl%C3%A9ment-drouin-785643137/)\*\*Software Engineer at Mistral AI \*\*[Louis Knight-Webb ](https://www.linkedin.com/in/knightwebb/)\*\*Vibe Kanban We will close the evening with a focused panel discussion and audience Q&A on coding agents, interoperability, and the future of agent powered development.

I'm talking about Nullable Reference Types. In this presentation, I we dig into this feature, explore why it exists, what problem it tries to solve, how it works, and how people have critiqued it, so that you as a programmer can decide if and how you want to use it.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
