It's our last event before the new year and it looks like a great lineup so far. We're also giving away a Scala eXchange ticket for a lucky attendee, so watch this space on how you can win!

We're excited to be returning to our hosts from the beginning, Equal Experts, based in Euston Square and hope to see many of you there.

We have talks from Chris Birchall at Ovo Energy and Mark Hatton from Shazam and César Tron-Lozai.

See below what we have in store for the evening;

6:30 pm: Doors Open

7 pm: Talk 1 - Chris Birchall - Ovo Energy

Title: Bring Your Own Effect

Recently there is a trend in Scala libraries abstracting over the effect container in which they wrap their computations, allowing users to choose the effect that makes sense for their program.

7:20 pm: Talk 2 - Mark Hatton - Shazam

Title: Building for Longevity with Scala

With engineers moving from project to project and company to company, how do we ensure the systems we are building can survive constant organisational & personnel change? Why do some systems outlive others? And if we are honest with ourselves, are we guilty of thinking much too short-term about our software systems?

Drawing from real world examples, I will discuss the Scala projects that succeeded long-term (5+ years) and those that quickly became obsolete. I will further characterise some of the unique obsolescence pitfalls that Scala and its ecosystem bring and how to avoid them.

We’ll touch on the lesser known aspects of the API and the importance of choosing the right execution context.

7.40pm: Talk 3: César Tron-Lozai

Title: Functional Sudoku Solver

In this presentation, we will be building a Sudoku Solver solely using Functional Programming idioms in Scala. This is a great opportunity to learn the very basics of Scala and the power of its built in Vector library.

This talked is aimed at Scala beginners or anyone else interested in discovering this powerful language (Java developers welcome!)

8 pm: Drinks and Pizza

9 pm: Pub!

Make sure to update your RSVP soon, you'll have seen if you've been before spaces are limited!

As always, if you’re looking to talk or get involved in any way in future meetups find us on the day or get in touch with Alice.

Looking forward to it and see you then!
