Speaker One:

Miguel Trigueira Software Engineer with vast experience building low latency systems

Talk: Java 25 LTS for Low Latency : A Whirlwind Tour

Between the last Java LTS (21) and 25n(which is scheduled to be out on 16 September 2025), there have been many changes that could be relevant to low latency systems. We will cover Concurrency and Threading, Garbage Collection and Memory Management, Performance and Optimization, and more.

Speaker one bio:

A pragmatic and analytical software engineer with over two decades of experience, I believe in making reasoned arguments and building simple, elegant solutions. I am passionate about robust testing and creating systems that are clear and maintainable. My experience includes everything from core Java to product management, with a constant focus on improving the craft of software development.

Speakers Two:

Ryan Healey Senior Software Engineer @ LMAX

Talk: The developers worked in two by two. Hoorah! Hoorah!

Pair programming can be a rather polarising idea.Some people love the idea of working with a colleague, 2 heads are better that one when solving a complex problem. Some can see the benefits, but it’s just not for them, they’d rather work alone and focus. Others see pair programming as intimidating or toxic, why should I need someone sitting over my shoulder judging my every keystroke? Finally, managers think pair programming is a waste of precious resource, why should I pay 2 people to do 1 person’s job? Well, let's have the debate.

Let’s explore the pros and cons of pairing. When pair programming makes sense, and when it doesn’t. How to make a pairing session effective and what habits you might have that are sabotaging your pairing time. What makes a good pair and what makes a bad pair. What is extreme programming, and does it work?

Finally, it wouldn’t be a talk these days if I didn’t mention AI. Does AI change the way we pair program? Can you pair program with AI?Hopefully some of you will give pairing another go. Maybe others will see the faults in their ways and fix the bad habits they have in pairing. And maybe even some of you might realise that management was right all along, why are they paying 2 of us to do 1 person’s job. Let’s find out.

Speakers two bio:

Bioengineer turned programmer with 5 years professional experience at THG and LMAX, Ryan might not have as much experience in the game compared to most but he's keen to learn and eager to share what he's learnt. He's a strong believer that coding should be fun and easy and hopes that he can help make your lives fun and easy too.
