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

Programming languages are a large amount of our day to day work and, for some of us, our hobbies. And I am very much of the opinion that in order to fully understand our tools, we must be able to make them ourselves.
In this talk, I will show you how to create a programming language from scratch. You will come away from this with a deeper understanding of, and insights on, your tools. It will also teach you what you need to write powerful DSLs, which in my experience can be an absolute game changer when maintaining software whose purpose I'm not an expert on, but I do have access to experts.
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.
During the talk, we’ll build a small effect system using solely Scala 3 context functions step-by-step.
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.
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.
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.
