Oracle Database Administration

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/).

PLEASE CLICK HERE TO PURCHASE A TICKET:** [Speed Dating london – The Anthologist, Bank (Ages 28-42) – Tuesday, 23rd Jun 2026 | True Dating](https://truedating.co.uk/events/christian-speed-dating-23-jun-2026) Reaching a point in life where you’re ready to settle down and build something meaningful can sometimes feel isolating, especially when you’re hoping to meet someone who shares your Christian faith and values. **That’s where Christian speed dating comes in.** At our events, you’ll have the opportunity to meet up to 15 like-minded singles in one evening. Each date lasts around five minutes, enough time to have a genuine conversation and see whether there’s a connection. Ladies remain seated while gentlemen rotate. Our guests are typically working, successful Christian professionals who are tired of endless swiping and are genuinely looking for something long-term. Everyone attending has signed up in advance, is single, and is there for the same reason as you. The atmosphere is friendly, relaxed, and welcoming, with experienced hosts on hand to guide the evening and help put everyone at ease. After the event, you’ll submit your matches online. If there’s a mutual connection, you’ll be able to message securely the following day and hopefully arrange date number two. ### Why Speed Dating? Speed dating events are more popular than ever in London as people move away from dating apps and back towards real-life connections. If you’re wondering whether events like this are awkward or not “your kind of crowd,” you’re not alone — but that perception has changed completely. ### What to Expect on the Night * A well-organised, hosted event * A room full of single Christian professionals * A safe, structured environment * The chance to meet multiple potential matches in one evening ### Event Details * **Start time:** 7:30pm * **Location:** Exclusive area reserved — please ask venue staff for **True Dating** if needed Places are limited and our events often sell out, so we recommend booking early to avoid disappointment. **Stop swiping. Start dating.**

**Please register on [Eventbrite](https://www.eventbrite.co.uk/e/ljc-meetup-at-capital-one-tickets-1990857451229) to join this event.** LJC Meet-ups is a series of events, aimed at giving all Community members an opportunity to present at an LJC event. Join us on 25th June 2026 for a London Java Community meetup hosted at Capital One. **Speakers:** **Melinda Seckington** \- Leadership & Speaker Coach **Topic:** *See It, Say It, Sort It: How To Be More Proactive* It's really easy to fall into a reactive rhythm as an engineer. A ticket comes in. You pick it up. Someone else makes a decision. You adjust. Before you know it, you've spent weeks doing good work… but not necessarily shaping what that work is. The engineers who have the biggest impact aren't the ones who simply deliver. They're the ones who pay attention, spot opportunities early, and take action without waiting to be asked. Proactiveness is a skill, a mindset, and a practice. And it can be learned. In this talk, we'll look at a framework for proactiveness: Awareness + Intent + Action. We'll explore how you can increase your awareness of what's happening around you, clarify the impact you want to have, and recognise the blockers that stop you from taking the next step. **Speaker bio:** Melinda is a trainer and coach, working with engineering teams and leaders to improve their communication, management and collaboration skills. She previously was an engineering manager at companies such as the Wikimedia Foundation and FutureLearn, where she focused on creating great internal engineering cultures. She’s an international conference speaker and has spoken at over 50 conferences, covering topics from good management practices to becoming a better speaker. **Stephen Galbraith** \- Staff Engineer at Capital One **Topic:** From Fleeticide To Recovery: When Your Auto-Scaling Policy Becomes Your Worst Enemy Horizontal scaling sounds simple in a README, but the reality of a Spring Boot fleet on ECS can quickly turn into "Fleeticide.” We've all seen it: connection pools saturate, health checks flap, and suddenly your auto-scaling policy becomes an auto-failing policy. In this session, we go behind the scenes of a real-world challenge caused by lack of scaling. We'll dissect our initial assumptions and dive into the technical shifts that dramatically reduced downtime. We will move beyond "CPU/Memory 101" to look at: The Observability Gap: Tracking the "hidden" metrics (Thread pools, DB connections) that reveals how much headroom a service has. AWS Patterns for the Real World: Moving beyond basic CloudWatch alarms to custom metrics and predictive scaling that respects Spring Boot's startup overhead. Architecting for Elasticity: How to bake scaling-awareness into the developer workflow to prevent connection storms and cascading failures. **Speaker Bio:** Stephen Galbraith, Staff Engineer at CapitalOne. Steve has been at Capital One for 11 years and has used Java since the Java 1 days. He has worked on software for Computation Fluid Dynamics, Space Mission Analysis Software and Foreign Exchange Trading before moving into his current role at Capital One. Currently, Steve focuses on Site Reliability Engineering, specifically analysing software failures and developing preemptive solutions to increase service availability for Capital One's customers, aiming for the magical triple nine target. Huge thanks to our friends at **Capital One** for sponsoring this event and supporting our Community.

**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 **8:10pm: 🗣️** **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. **8:40pm:** Raffle Winners! **9:00pm:** Pub! ==== 🎉 **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\!
