After dinner, there’ll be a few optional activities to dip into if you fancy – from Cheese & Port tasting and Horse Racing, to Board Games and an interactive quiz. The bar will be open until 11pm for anyone who wants to stick around and enjoy the evening vibe. Please note the bar is card only and if you wish to recharge to your room, you will need to organise this at Reception beforehand.

Taming the Legacy: How We Revived a Massive Akka Scala System Without Rewriting It
Join Flui and walk through the journey of transforming a critical, performance-struggling Akka Scala application — a legacy system over a decade old — into a stable, efficient platform without a full rewrite. 
When one of our key clients issued an ultimatum due to message loss, timeouts, and memory issues, our team mobilized quickly. With minimal documentation and deep architectural complexity, we formed a focused performance task force, brought in Akka Scala expertise, and prioritized smart, iterative improvements. 
If you're dealing with aging code, mission-critical performance issues, or weighing rewrite vs. refactor, this talk will offer practical lessons and confidence that even old systems can deliver modern results.
