**Hello There! And welcome to our June Gophers @ Meta event!** It's immensely exciting that we'll be visiting Meta for our June event, but with great big office comes great responsibility, so it is **CRITICAL THAT YOU HEED THESE ENTRY REQUIREMENTS!** * You MUST bring Government Issued Photo ID with you, matching the name with which you sign up to this event * You MUST complete the NDA that will be emailed to you in advance of the event, before arrival * You MUST be over 18 years old * You MUST NOT record when inside the venue * You MUST wear the lanyard provided to you on the night at all times And needless to say, if you satisfy all of those criteria and manage to make it through security without being tackled, you MUST have a lovely time otherwise you know I'll be giving you a hard stare. A massive thank you to Meta for hosting! See you all there! ==== 📓 **Agenda**📓 ===== (Certain timings and orders may be subject to change) **5:30pm onwards:** Sign-In, Food & Refreshments **6:55pm:** Introduction **7:00pm:** 🗣️ **Jon Bodner: Testing Go: From the Basics to synctest** Testing is fundamental to software engineering and as a language focused on software engineering, Go includes a wide variety of tools to ensure your code is working as expected. I’ll walk through the basics of testing in Go, and then cover some of the more advanced tools: benchmarking, fuzzing, and the new synctest package. **7:40pm:** Raffle and Break **8:00pm: 🗣️** **Oleg Obleukhov: Time @ Meta** Discover how Meta uses Go to build PTP and NTP - open-source, highly efficient time synchronization systems that achieve nanoseconds precision. **8:30pm:** Break **8:40pm: 🗣️** **Simon Emms: Failure Happens. Your Code Shouldn't Care** As Gophers, we expect our code to be retried, restarted and run more than once. The challenge is making that safe and maintainable without layers of defensive plumbing. Temporal lets us write reliable workflows in Go that automatically recover from crashes and restarts, while still looking and feeling like normal Go code. In this talk, I’ll explain how it works and prove it with a live demo that treats failure as just another code path. **9:10pm:** Raffle Winners! **9:30pm:** Pub / Socialize ==== 🎉 **Prizes & Discounts!** 🎉 ===== **JetBrains Raffle!** \- We have 3 free JetBrains Product licenses to give away to some of our lucky attendees\! **Ardan Labs Raffle!** \- We're giving away one course license for Ardan Labs' Ultimate Go Bundle\! **Manning Publications Raffle!** \- We're giving away 4 free Go e\-books\! **45% Manning Publications Discount** \- a massive discount provided by the fine people at Manning\!

This June we're at FundApps offices in HYLO, Bunhill Row. Chris Simon's back in town, and will be joining us to talk about streams and queues; plus Tiago Sousa from SteelEye will be talking about the work they're doing around using AI in comms surveillance. Our hosts at FundApps will be providing drinks and snacks, and there will be plenty of time to chat beforehand and in the pub afterwards. **Chris Simon: It's like 10,000 streams when what you need is a queue** *🎶🎵 A new dev team adopted E-D-A* *Got head of line blocking, on their very first day* *Isn't it ironic, don't you think 🎶🎵* The last few years have seen widespread adoption of Event-Driven Architecture, supported by DDD practices such as event storming. But what does that orange sticky note become when we start implementing our design? Common implementation choices include event sourcing, streaming platforms like Kafka and queuing systems like RabbitMQ. Unfortunately not every orange sticky note has the same operational needs, and many teams remain confused about the differences between these options, resulting in the selection of the wrong paradigm for their needs. This can lead to unnecessary complexity & operational challenges such as head of line blocking, dropped messages, challenges dealing with failed messages, difficulty with adaptive scaling and inadvertently increasing coupling between services. In this talk we'll bring that orange sticky note into the runtime of our system. We’ll start with a deep dive into the similarities and differences between event streaming platforms such as Kafka and queueing systems such as RabbitMq, Azure Service Bus & AWS SNS/SQS. We’ll then look at ways to assess your orange sticky notes to work out which messaging and persistence paradigms suit each one, helping you build more resilient, scalable and loosely coupled event-driven architectures. **Tiago Sousa: AI in Comms Surveillance** In this talk, Tiago shares what it's actually like to build AI for communications surveillance at SteelEye. Financial firms are required to monitor and flag communications for compliance, but making AI work reliably in that context is harder than it sounds. He'll walk through real examples from the trenches: what worked, what didn't, and what he'd do differently. **Tiago Sousa** is a Staff Data Engineer and AI Lead at SteelEye - a platform that helps financial firms monitor and flag communications and trades to stay compliant with regulations. He's spent the last five years building the data and AI systems that make that work. Before that, he did research in bioinformatics, which means he came into fintech from an unusual angle and has the scars to prove it. He's based in Braga, Portugal.

For our event, we have reserved an area of the venue so that we can mix and mingle and meet old and new friends, new contacts, and new clients too! We encourage everyone to talk to as many people in the event as possible. That said, once you feel a certain chemistry or opportunity with someone, we encourage to talk with them on a deeper level. We forget about 90% of people after a goodnight sleep. However when we establish an emotional resonance with someone, they will remember us the next day. Program: The evening's format is designed for networking in a relaxed setting, providing an opportunity to meet fellow business leaders, entrepreneurs, and investors. We emphasize building genuine relationships on a personal level. I will be there to help with introductions and get over the barrier of anxiety when approaching someone you don't know. How many people are attending? The venue has a capacity limit of 80 guests, and due to the popularity of our events and the unique ambiance of the location, we anticipate this event will reach full capacity quickly. We strongly advise securing your reservation early to ensure attendance. If you haven't gotten a ticket, you can pay when you arrive but it will be 50% more expensive than buying it in advance. Our events achieve success through a straightforward yet impactful strategy. A few days prior to the event, we establish a WhatsApp group for attendees interested in pre-event networking, enabling participants to arrange meetings both for the event day and beforehand. On the day of the event, you will experience a relaxing atmosphere with a hospitable and encouraging community.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
