Direct-style Effects Explained

Direct-style effects, also known as algebraic effects and effect handlers, are the next big thing in programming languages. They are already available in Unison and OCaml, are coming to Scala, and I’m seeing discussion about them in other closely-related-to-industry contexts.

How to build AI apps with Scala 3 & Besom

How to combine sttp-openai, tapir, k3s, PostgresML, and Besom to build a robust an elegant solution.

Spec-first and code-first, hand in hand

Yesterday, I released smithy4s-deriving, a Scala 3-only library that provides meta-programming-based derivation mechanisms for the core abstractions of Smithy4s. These abstractions, which act as the foundational pillar to Smithy4s, are usually code-generated by the build-plugins provided by the library, using smithy as a source of truth.

Updating our Smithy4s stack in 2024

Since the last video, we've had some version updates, and there's a new cool feature (smithy4sUpdateLSPConfig). Let's go over these together.

My first year in Scala

In this talk, Monica will cover three key concepts that emerged from reflecting on this past year of learning: 1. Making Mistakes, 2. Helping Others to Help You, 3. Finding Community.

Elements of JVM concurrency

Shared-memory concurrency can be challenging, and many don't have the confidence to fix concurrency problems. In this talk, I hope to inspire some confidence by presenting concurrency concepts of the JVM, to build the needed mental model, also exemplifying some utilities from Cats-Effect. We'll do so via wheel reinvention, implementing concurrent queues.

The Effect Of Uncapturable

A syntactical stroll through algebraic effects, unique types, and lifetimes to the new version of "capture checking" in the upcoming Scala versions with dreams and fantasies about the future of Scala programming.
