What can one tiny function teach you about twenty years of Scala? We rewrite `isPalindrome` version by version and let the code tell the story. Watch it grow from classic Scala 2 i…
For 14 months, the Scala Project worked with Open Source Technology Improvement Fund, Inc and the Sovereign Tech Agency on a plan to improve the security posture of the project. Th…
Learn more about Typelevel, the open source organization that stewards development of projects such as Cats Effect, http4s, and Circe, and offers one of the most comprehensive cros…
We will present our ongoing work to bridge between Scala 3 (& Kotlin) and Python 3 using GraalVM. We will explain how the interoperability was designed; how type hints map to Scala…
AI agents now generate many Spark data pipelines, but the untyped DataFrame API makes subtle data bugs easy to ship. This talk introduces Wick, a type-safe Spark API that encodes s…
Learn how to accelerate Scala code by orders of magnitude with Cyfra. There are many libraries that give you access to low-level GPU APIs, but a high-level, functional one is a di…
What if assertions such as `x > 0` were part of the type system? We present a prototype implementation of _logical refinement types for Scala_: types like `{x: Int | x > 0}`. In ou…
Object-oriented programming helped shape modern software engineering - but also gave us shared mutable state, fragile hierarchies, and accidental complexity. Using real Scala adopt…
Everyone and their dog are building permanent AI agents, but nobody is solving the real problem – how to prevent the agent from doing something it should never, ever do while prese…
