Continuous Integration

On 23 June we will be gathering at the Star of Kings for some Postgres and a pint. This time we'll have a talk by **Andreas Karlsson** from Percona on **Stopping Collations Going Wrong**, followed by a brief recap from **Alastair Turner** (Percona) and **Valeria Kaplan** (Data Egret) on **this year's PGConf.DEV**, where the PostgreSQL community celebrated its 30th birthday. This event is generously sponsored by [Nexteam](https://nexteam.co.uk/), a London-based consultancy specialising in PostgreSQL-based solutions, database support, and bespoke software development. We are a very informal bunch, so hoping to see you and your colleagues there! We do need to know the numbers, so please register if you are planning on coming. WHERE The Star of Kings **on 23, June from 18:30.** PROGRAMME 18:30 Welcome 19:00 **Stopping Collations Going Wrong** (Andreas Karlsson, Percona) - More below! 19:45 Food and bar snacks 20:00 **Celebrating 30 Years of Postgres at PGConf.DEV** (Alastair Turner, Percona & Valeria Kaplan, Data Egret) 20:30 It's a pub, so we'll stay and hang out a bit longer — but feel free to leave whenever you prefer! About The Talk **Stopping Collations Going Wrong** Outside of causing trouble for you when upgrading libc what are collations good for? PostgreSQL's collations have gotten a lot of bad press from the upgrade issues but they are also a powerful and important tool, especially for working with text in other languages than English. This talk will give an introduction to collations in PostgreSQL, including how to use them, what they are useful for, how they work plus some common pitfalls and misunderstandings. You will learn, among other things, about the three collation providers (libc, icu, builtin), BCP 47, case insensitive collations, CTYPEs, what new features have been introduced in recent PostgreSQL versions and get a brief look into the future of collations in PostgreSQL. About The Speaker **Andreas Karlsson** is application developer and long time minor contributor to PostgreSQL who recently has started working with PostgreSQL full time. Right now working for Percona with PostgreSQL itself and extensions, including pg_tde. \*\*\* THE OFFICIAL BITS The meet-up abides by [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/).

Hey everyone, We’re back with a new edition of the AI Security Engineers Meetup in London on June 23rd with 2 great talks! **Talk #1 - Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for safety** In the rush to build autonomous agents, we face a fundamental tension: the more freedom we give an LLM to solve complex problems, the more likely it is to drift into “stochastic hallucinations” or policy violations. Most safety efforts focus on restricting the model via prompts, which often stifles the very reasoning capabilities required for sophisticated tasks. This talk introduces InsideOut, a design pattern that prioritizes agent autonomy by implementing deterministic checkpoints. Rather than micro-managing the agent’s “thoughts,” the InsideOut architecture allows the agent to navigate freely through a task—provided it periodically “grounds” its progress in structured, verifiable artifacts such as JSON or Markdown. We will walk through a real-world application of this method: an agent designed for setting up and managing cloud infrastructure. The agent is given the autonomy to discuss and decide on Features, Stack Components, Configurations, Cost Estimates, Terraforms, Deployment, and Management. To ensure reliability, each stage requires the generation of a JSON artifact validated against deterministic rules. If a boundary is breached, the agent is triggered to repeat that specific stage until the output is within bounds, preventing error propagation. By drawing a parallel to the concept of a Brownian Bridge versus Brownian Motion, we illustrate how these checkpoints act as “pins” that anchor a random walk. This approach demonstrates how forced artifact crystallization allows an agent to design and deploy complex stacks with high independence and zero “drift.” This session provides a framework for building agents that are more productive because they are safely unconstrained. Speaker: Hossein Kakavand. Hossein did his Ph.D. at 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. **Talk #2: Agentic Development Security: Securing the AI Workforce** AI agents are rapidly becoming part of the software development lifecycle, writing code, interacting with tools, and making decisions with increasing autonomy. But as organizations embrace agentic development, a new set of security challenges emerges: How do you trust the tools agents use? How do you prevent dangerous actions? And how do you ensure the code they generate is secure? In this session, we'll unveil and demo Snyk Agentic Development Security, a new approach to securing both AI builders and the AI-powered tools they rely on. You'll see how organizations can secure the agent supply chain by vetting MCP servers, plugins, and external tools before agents interact with them; govern agent behavior through real-time policies that prevent destructive actions with Agent Guard; and ensure trusted output by automatically detecting and fixing vulnerabilities in AI-generated code at the moment of creation. Join us for a live demonstration of how security can keep pace with the rise of autonomous development, enabling teams to innovate confidently while maintaining control, trust, and resilience across their AI workforce. Speaker; Denis Kent - AI Security Engineer at Snyk. Denis is an AI Security Software Engineer at Snyk, building Evo, Snyk's agentic security platform. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- As always, expect great talks, free pizza and drinks, and even better company. 📍 **Where**: Snyk Offices, 24 Eversholt Street, London (Euston tube station is right across the street) 📅 **When**: June 23rd ## Agenda **6:00 PM** – Doors open **6:00 PM – 6:30 PM** – Food & drinks **6:30 PM** – Talks begin **7:30 PM** – Talks end & social time **8:30 PM** – Doors close Looking forward to seeing you there!

Join us on Thursday 25th June for our next AI Exchange event, hosted by Coralogix at their London HQ in Devonshire Square. Pioneers of autonomous driving, **[Wayve](https://wayve.ai/),** are exploring how Agentic AI can be integrated into software development in a measurable and trustworthy way. **[Cato Networks](https://www.catonetworks.com/)** are applying AI to one of cybersecurity's most overlooked problems: the hidden risks buried within complex security policies. Finally our hosts **[Coralogix](https://coralogix.com/)** are addressing a challenge many engineering teams are beginning to face: AI coding agents are becoming part of everyday development, but very few organisations have visibility into how they're actually performing. **\*\*Please make sure to head to the to [AI Exchange Meetup page](https://www.meetup.com/ai-exchange/events/315038797/?eventOrigin=group_upcoming_events) to register for this event\*\*** As always, doors open at 6:30pm and talks start at 7pm sharp. We have another tight capacity for this event, so please RSVP as soon as you can to secure your space. **Agenda:** **[Lewis Isaac](https://www.linkedin.com/in/lewisjamesisaac/) @ [Coralogix](https://coralogix.com/)** **Who’s Watching the Agents? Observability for AI-Assisted Development** Code agents are already in your engineering workflow. The problem is that most organisations still have no visibility into what those agents are actually doing. How many tokens are they consuming? How long are tasks taking? Are they introducing regressions? Are they measurably improving delivery, or just creating the feeling of progress? The gap between “we have AI tooling” and “we understand our AI tooling” is where most teams are stuck right now. In this talk, I will show you how OpenTelemetry can be used to instrument code agent workflows end-to-end, and how Coralogix Code Agents Observability brings all of those signals -token usage, cost, task duration, and code quality impact - into a single view. *Bio: Our speaker will be Lewis Isaac, Dev Relations @Coralogix bio Lewis is a Developer Advocate at Coralogix, where he works closely with developers to explore smarter approaches to observability and how deep technical telemetry can be connected to meaningful business and user outcomes. Prior to joining Coralogix, he was a Tech Lead at IBM, where he led the technical delivery of mobile application projects for clients including BP and a major UK bank.* **[Dave Kirk](https://www.linkedin.com/in/david-kirk-jr/) @ [Wayve](https://wayve.ai/)** **Agentic Code Review @ Wayve** At Wayve, we have been pursuing an approach to Agentic workflows that prioritises observability and evaluation of quality of work. Our Agentic Code Review pipeline has been at the forefront of this initiative. In this talk, we'll discuss some of the approaches and lessons learned over the past four months of operating this pipeline *Bio: Dave Kirk has been programming for over 20 years, and doing so professionally for a decade. His career has primarily been focused on cloud infrastructure and development workflows. He is now the lead engineer in Wayve's effort to adopt agentic AI as an impactful part of our SDLC and beyond.* **[Avidan Avraham](https://www.linkedin.com/in/avidan-avraham-04416498/) @ [Cato Networks](https://www.catonetworks.com/)** **Autonomous Policies Using LLMs to Sweep Up Misconfigs** Security policies and engines today are complex ecosystems - not just defined by rigid, structured configurations but also by many layers of free-text and meta-data that tell the real story behind a rule or a configuration. Traditional configuration analysis can flag obvious issues, yet it often overlooks the contextual “crumbs” left behind by temporary fixes, ad-hoc tweaks, or legacy testing exercises. These remnants, much like orphaned data in a software system, can create unexpected vulnerabilities that attackers are eager to exploit. In this talk, I introduce a pioneering AI-driven strategy inspired by the concept of a software Garbage Collector. Just as a Garbage Collector continuously cleans up memory leaks, our AI agent proactively sifts through the meta-configuration, analyzing unstructured fields—free-text names, descriptions, annotations, and even multilingual notes—to identify contextual misconfigurations before they evolve into high-risk liabilities. Advanced NLP is key: semantic analysis decodes the intent behind free-text entries, while contextual classification organizes policy components by interpreting diverse cues. This integrated approach detects anomalies that traditional tools may miss, shifting policy management from static settings to dynamic, context-rich narratives that reveal hidden security gaps. We hope to see you there for another great AI filled evening! **Sponsors...** The AI Exchange is brought to you in partnership with[ LinuxRecruit](https://www.linuxrecruit.co.uk/) and[ AWS.](https://aws.amazon.com/) LinuxRecruit is building the next wave of Tech Unicorns in Europe.

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.

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

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. 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.
