In this presentation, I will demonstrate how we leveraged the strengths of Scala and TypeScript to develop a collaborative text editor that meets the strictest standards for security, performance, and real-time collaboration.

Have you ever wondered what it takes to combine the power of Scala with the flexibility of TypeScript to create a secure, real-time collaborative text editor—similar to Google Docs, but built for high-security environments? Imagine a scenario where military teams need to simultaneously update critical text documents during a mission, while ensuring airtight security in air-gapped deployments.
In this presentation, I will demonstrate how we leveraged the strengths of Scala and TypeScript to develop a collaborative text editor that meets the strictest standards for security, performance, and real-time collaboration. I will dive deep into the technical architecture, powered by advanced operational transformation algorithms, which enables multi-user editing without conflicts. Additionally, I'll share how we layered robust security measures on top of the solution to ensure it meets military-grade standards, while maintaining seamless performance in isolated networks.
We'll explore type classes in Scala 3, using its new rules for givens, extension methods, and mechanisms for automatic derivation via mirrors or macros.
In this talk, I will present insights from running the Open Community Build, where we continuously build and migrate nearly 2,000 open-source projects to the newest Scala Next versions, from scratch, every week.
This will be a live coding demonstration of Scala's newest feature set: capture checking.
I would like to present the use of NamedTuples to implement some cool things in SQL Libraries
In my talk I will argue that we can do much better by relying in a systematic way on types and capabilities.
In this talk, I will introduce the highlights of what to look forward to in Scala 3.9 LTS, as well as how to think about the upcoming new release.
