Lightning Talk - Exploring Phantom Types: Compile-Time Checking of Resource Patterns
Featuring Joey Capper
The Dotty platform comes with a host of new and revised language features that aim to simplify the Scala landscape. In this talk you take a brief look at one such feature: Phantom Types.

Impromptu: Using Dependent Types to Build a Better API for Async Call Graphs
Featuring Jon Pretty
Writing asynchronous code is often an uneasy fit for a language like Scala. While high-level constructs like Futures facilitate asynchronous programming, syntactic limitations often make blocking or the unchecked access of asynchronously-computed values more natural than the safer alternatives.

Away With the Types!
Featuring Dave Gurnell
Static types are fantastic for ensuring code quality, but rather annoyingly they have to be defined at compile time. What happens when you need to determine the structure of your data at run time, for example when you have to load schemas from a database?

Refinement Types in Practice
Featuring Peter Mortier
When you first learn scala, coming from another language such as Java, you'll probably fall in love with the Option type. This type protects you from bugs because you know that the value wrapped in an Option might be absent and if you have a plain value, you know it will never be null.

Automatic Parallelisation and Batching of Scala Code
Featuring Gjeta Gjyshinca and James Belsey
Morgan Stanley has developed a technology that allows the widespread automatic parallelisation of execution. James and Gjeta are part of a team who, using the Scala language and ecosystem, have built a runtime that automatically parallelises users’ Scala code. During this talk, you will discover...

Keynote: The Magic Behind Spark
Featuring Holden Karau
Apache Spark is one of the most popular general purpose distributed systems, and has driven a lot of growth in the Scala community. This talk will look at the magic which makes Spark work, peeling back the curtain to revel the several hundred gnomes that secretly power most distributed systems.

Lightning talk - Optic Algebras: Beyond Immutable Data Structures
Featuring Jesus Lopez Gonzalez
Optics (Lens, Traversal, etc.) are great abstractions that allow you to carry out complex state transformations using high-level design patterns. However, current optic libraries are restricted to work with in-memory data structures. In fact, this limitation might be one of the causes why optics...
