After some investigation, I found that Home Assistant has an integration with Node-RED - a graphical tool for manipulating data and event streams. It could probably satisfy most of my needs. But from time to time I remember that I'm a professional software developer, working with event streams for many years, and for this kind of problem there's nothing better than math (and Scala's type system, which supports it very well).

His first solo single was a cover of Elmer Bernstein's theme from The Man with the Golden Arm, and his debut solo album, Moss Side Story, was a soundtrack to a nonexistent film noir. He's gone on to compose scores for actual soundtracks, like new documentary SCALA!!!, which is about London's infamous arthouse cinema from the '70s and '80s where Adamson spent a lot of time.

Imagine you're working with a third-party library that provides a User class. You need to add JSON serialization to it, but you can't modify the source code. Of course you can create a wrapper class or extend it, but that feels clunky and breaks existing code that expects the original type. This is where type classes shine. They're one of Scala's most powerful patterns, and they're the secret ingredient in popular libraries like Cats, Scalaz, and Circe.

When it comes to Scala interviews, the trick isn't just solving problems - it's solving them the Scala way.Interviewers are often less interested in whether you can code something and more curious about how you think, use language features, and write clean functional code. In this article, I'll walk through three interview-style Scala questions. Each question is designed to test a different dimension of your Scala skill set - from string manipulation to functional collections and stack-based problem solving.

Slick (short for Scala Language Integrated Connection Kit) is one of the most widely used libraries in the Scala ecosystem for functional, type-safe, and composable database access. It provides a clean DSL for querying SQL databases while staying true to Scala's functional style. In this article, we'll explore: What Slick is and why it matters How to set up a Slick environment in a Scala project Basic CRUD operations with examples Slick in Play Framework vs. standalone Scala apps Common pitfalls and best practices

Working with Amazon S3 buckets in the Kubeflow Spark Operator and Python is complicated, with issues surrounding dependency management and file access within worker pods.

The Scala Days 2025 sponsors provide crucial support for gathering the Scala community, fostering connections and showcasing innovative products and services.

A higher order function can take another function as a parameter and may return a function, which simplifies certain programming tasks in Scala.

ZIO uses a lightweight concurrency model based on fibers, enabling efficient execution of thousands of tasks concurrently on few actual JVM threads.

Sangria GraphQL offers a robust implementation for Scala, enabling developers to create expressive and efficient GraphQL APIs while leveraging Scala's type system and functional programming principles.

Scala's unique integration of object-oriented programming and functional programming paradigms empowers developers to write concise, expressive, and highly concurrent code, making it an ideal choice for modern software development.

Real-world ZIO workshop focuses on leveraging ZIO to create provably correct systems and fully utilize Scala 3 for practical application development.

Workflows4s combines type-safe definitions, event-sourced persistence, and rich operators to create a unique, cohesive solution for workflow automation in Scala.
