London Scala User Group

💻 Hands On Session with Creative Scala 💻
Bring your laptops for this event because we'll be getting hands on!
In this session, we'll be programming with Creative Scala - a fun way to explore and practise functional programming with Scala.
Whether you are completely new to Scala or experienced with functional programming, all levels of experience are welcome! Perhaps you're looking for some help getting set up as a beginner. Perhaps you want to practise your programming skills with peers. Perhaps you want to take a break from your day job and flex your curiosity in a fun environment! Sit back, relax, explore, and learn by doing... ✨

🗣️ Zainab Ali: Taking the plunge: a deep dive into streaming with fs2
We often think of streaming as a niche concern: something that occurs in large scale data-intensive systems, or event driven architectures. But streams are a lot more versatile than you might suspect. In fact, they form the cornerstone of almost every useful Scala application.

In this talk, we’ll navigate the rich waters of streaming.

Using the lens of `fs2`, a functional streaming library, we’ll explore how certain problems can be expressed much more easily using streams. We’ll spot the more obvious streams in event-based systems and data processing, webservers and databases, but also discover more subtle streams in time-based processes and concurrency challenges.

We’ll learn what streams are for, how to think about them, when to use them and when not to. By the end, you’ll see a streaming framework as a simple and versatile tool in your toolbox, and will feel confident putting it to use in any area of your codebase.

Are you going to Scala Days ?

🚂 Let's make the trip together on the Scala Days Train Jam!

Join fellow Scala developers and hack on projects on the train. The train jam starts at London, goes via Paris, and ends at Lausanne.

If you're a frequent traingoer or just taking your first steps in sustainable travel, the train jam is the journey for you!

Agenda ​

• 8:15 Assemble at St Pancras
• 9:31 Take the Eurostar to Paris
• 12:58 Arrive in Paris and head to Gare de Lyon
• 14:18 - Take the TGV to Geneva
• 17:29 - Arrive in Geneva
• 17:54 - Leave Geneva
• 18:37 - Arrive in Lausanne 🎉

Questions
How much is the train fare?
If you book now, it’ll be roughly £230 - £250 depending on whether you’re booking a return.

How do I book tickets?
Read our guide for train jammers for a step by step booking process. ​

Is there Wifi on the train?
Yes! There’s Wifi and generally good signal on the Eurostar, TGV, and in Gare de Lyon, where we’ll spend most of our journey.

What will we jam on?
Whatever you like! Along the way we’ll contribute to OSS projects, or hack on fun and interesting ideas.

I’ve never taken the train in Europe. Is it hard?
Not at all! Taking the Eurostar and TGV is very smooth. The difficult bit is booking tickets (see How do I book tickets? above). The most tricky part of our journey is crossing Paris via the metro, and we'll do that as a group.

Why are you going a day early?
We’re going in time for the Scala Days workshops and Scala Bridge. If you’re not attending either of these, we strongly encourage you to spend the day hacking together, or to join in other events. ​

I want to go by train, but can't take this one. Are there other trains I can take?
Of course, although you might not be with other jammers. Our guide for train jammers has some alternative journeys already planned out.
