Taming the Context Beast

Featuring Paweł Marks

Context functions are the new beasts in the Scala jungle. I’ll show you what they can do, when to be wary of them, and how to tame them. Finally, I’ll answer whether they really hate composition as much as it’s rumored.

What Logic can Teach Us, Scala Programmers

Featuring Juan M. Serrano

It turns out that logic is a great source of exercises for mastering algebraic data types, dependent types and other Scala features. Take the challenge of using Scala 3 to prove Aristotle’s syllogisms or Smullyan’s logical puzzles, and bring your type-driven development skills to the next level!

The Middle Way for Static Typing in Spark DataFrames

Featuring Alfonso Roa

No static typing with DataFrames, too much static typing with Datasets. Steer clear of both extremes, and embrace a new proposal of typed column expressions! Brought to you with the help of functional programming patterns, Scala idioms, cats, shapeless and other libraries of the Scala ecosystem.

Speck Flavored Streaming Micro-Services with Akka

Featuring Andrea Zito

In this talk, we will dive into the world of streaming micro-services and we’ll explore together the typical development journey starting from the raw input, all the way to a persisted, clustered prototype. This will be possible by leveraging Spekka’s productivity enhancements to Akka Streams.

Say Goodbye to Implicits – Contextual Abstractions in Scala 3

Featuring Magda Stożek

Scala 3 is out, but is it worth switching to? In my opinion, yes, because the authors addressed some important pain points, and for sure implicits are one of them! In Scala 2 they’re used, confused and abused - let’s see how much better it is in Scala 3.

Building a Debugger for Scala 3

Featuring Adrien Piquerez

Building a debugger for a high-level programming language like Scala 3 is a challenging task. In this talk I will decompose it in smaller problems and describe our solutions: a debug server, an expression compiler and a step filter.

Getting Started with Scala.js, Laminar and Vite

Featuring Sébastien Doeraene

Starting from scratch, we build a small Scala.js (https://www.scala-js.org/) application with a minimal, live-editable bar chart. We show a setup for a fast save-refresh cycle. We use Metals, sbt, Vite, Laminar, Chart.js and ScalablyTyped. Includes an intro to the FRP model of Laminar.

Function Reuse is just Wishful Thinking

Featuring Nicolas Rinaudo

Functors, monads, etc… can be both very useful and extremely intimidating.

This talk will introduce and justify them in a real life scenario, staying away from their more academic interpretations. It will allow attendants to build a solid intuition for the problems they actually solve.
