This talk will be a quick introduction to the Unison "paradigm" and language, from the perspective of a long-standing Scala programmer.

Unison is a young programming language for the cloud, built in particular by the authors of the Scala Red Book and other people who are (or were) active in the Scala community. Unison distinguishes itself from traditional programming languages by re-inventing the foundations of code storage and deployment. By doing so, it unlocks a number of very interesting properties that are rather unique in the programming landscape.
This talk will be a quick introduction to the Unison "paradigm" and language, from the perspective of a long-standing Scala programmer. It'll highlight the benefit of this approach, as well as some of the caveats.
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, I'd like to share how the Iron library and features from Scala 3 helped us build a solution which is safer, more robust, and easier to maintain.
In this presentation you will learn the source of your issues, and a third way - sanely-automatic derivation which is fast to compile, fast to run, and easy to debug by its users.
In this talk, I'll look at the different uses to which tagless final is put to, and see what we can learn about when it is useful and when it just gets in the way.
