Whiteboxish Macro Powers with Named Tuples
The example in the original post tackles the problem of automatically adding lenses for the fields of a case class to its companion. I'll shamelessly steal the same example here.

Production-ready direct-style Scala
While some great solutions, like the cats-effect and ZIO libraries, provide the tooling for building asynchronous and concurrent applications, direct-style complements the Scala offering when it comes to backend development, modeling complex business domains, transforming data pipelines, and more.

Better Scala builds with the Mill build tool
SBT is one of the oldest parts of the Scala ecosystem. Very powerful, but also very complicated and difficult to understand and maintain. 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. From "hello world" build pipelines to massive real-world projects, this talk will explore the ways in which Mill makes build tooling *easy*, solving one of the longest standing pain points in the Scala community.

Slow-Auto, Inconvenient-Semi: escaping false dichotomy with sanely-automatic derivation
Are you using one of many type-class based libraries in Scala? Have you ever been forced to understand this “automatic vs semiautomatic” distinction? Did your builds slowed down when you started using the “derivation” thing? Did you ever hate your life when looking for a missing implicit? 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.
