Exploring JVM Innovations Through the Lens of Scala Native

Production-ready direct-style Scala

Running Scala on AWS Lambda as a native-image

Case study. Summary of over a year of experience building AWS lambdas using Scala 3, scala-cli, and GraalVM. Presentation of the open-sourced library providing custom lambda runtime developed for that purpose.

How Scala is made and how you can help?

In this talk I will explain the inner workings of an organisation that goes into releasing, maintaining and developing Scala and core parts of its ecosystem.

Going structural with Named Tuples

Scala 3.6 stabilises the Named Tuples proposal in the main language. It gives us new syntax for structural types and values, and tools for programmatic manipulation of structural types without macros. Can we, and should we, push it to the limit? Of course! let's explore DSL's for config, data, and scripting, for a more dynamic feel.

What does the functor do on the tree?

In this talk we'll see how to model a tree structure in Scala, take both imperative and functional approaches to tree traversal algorithms, and do some ASCII art at the same time.

Yo Dawg, Heard You Want To FlatMap Your Direct-Style

During the talk, we’ll build a small effect system using solely Scala 3 context functions step-by-step.

Scalable Onboarding: Easing New Members into a Scala Codebase

In this talk, I'll walk you through coding and design practices I've developed over the years, whilst onboarding new graduates into world of Scala (be it typelevel based API, Spark based ETL, or ML pre and post-processings), and how I made the process easier for people who didn't have much Scala experience beforehand.

Scala Sampler for Functional Soundscapes

Discover how functional programming can inspire creativity with the Scala Sampler, a digital music instrument developed for the Sounds of Scala web audio library.

Shaping the Clouds - Introduction to TypeOps

In our talk, we will introduce a novel approach to system design— TypeOps — in which the application and infrastructure layers are fused to provide unprecedented safety and productivity for Scala teams.

All the projects I didn't finish, and why it was worth it

In this talk, I'll go through a couple of these projects, and share some of what they've taught me, as well as how their legacy affected other projects in the ecosystem. And who knows, maybe you'll get inspired to try something crazy with Scala too?

Bazel: Do We Really Need Another Build Tool?

In this talk, I'll introduce Bazel, exploring its core concepts and the unique aspects that set it apart from other build tools. I'll dive into some typical challenges Scala developers might face when working with Bazel.

Retrying the retry design

In this talk, I will discuss why it's hard to use the power of RT to test side-effect-heavy apps.

Tagless Final for Humans

In this talk, I'll look at the different uses to which tagless final is put to, and see what we can learn about when it is useful and when it just gets in the way.

Automating template management process with Scala 3 and Iron

In this talk, I'd like to share how the Iron library and features from Scala 3 helped us build a solution which is safer, more robust, and easier to maintain.

From Zero to Production Faster Than Your Average Meeting with Pillars

I will demonstrate how Pillars can take you from zero to production in record time. By leveraging Pillars’ integration of well-known libraries, you can bypass the usual complexities of setting up observability (traces, metrics, and logs), database access, API calls, and feature flag management.

Do You Even Macro?

In this talk, we'll cover the essentials of macros, why they are useful, why you should care about them, and how to become as good as you need with them for practical purposes.

Unison, from a Scala perspective

This talk will be a quick introduction to the Unison "paradigm" and language, from the perspective of a long-standing Scala programmer.

Durable Event-sourced Workflow Monad... Seriously!

In this talk, I'll walk you through how workflows4s works, how it stands apart from tools like Temporal or Camunda, and why it just might be the better approach for modern, event-driven applications.

Slow-Auto, Inconvenient-Semi: escaping false dichotomy with sanely-automatic derivation

In this presentation you will learn the source of your issues, and a third way - sanely-automatic derivation which is fast to compile, fast to run, and easy to debug by its users.

Programming a Language

In this talk, I will show you how to create a programming language from scratch.

Better Scala builds with the Mill build tool

This talk will introduce Mill: a newer build tool that does everything SBT does, but better. Faster, simpler, easier, Mill democratizes the build so you don't need to be a build tool expert to work on it.
