How to write a fire shader In this how-to guide, we're going to look at one approach to writing a little shader that produces procedural flames. The main gap Indigo has to bridge is between the Functional world of Scala and the procedural world of WebGL. Dave Smith (@davidjamessmith)

Scala 3 goodies for Scala 2 developers Scala 3 introduces new syntax for old things and deprecates some of Scala 2’s infamous warts, many of which have been fixed (or made obsolete) by the new compiler. While some of the Scala 2 syntax still supported in Scala 3.0, it will be removed in Scala 3.1, so it’s best to migrate as early as possible. Igal Tabachnik (@hmemcpy)

Composable Scala Matchers: Introduction Pattern matching is a truly awesome feature and I like to describe patterns, jokingly, as the “dark” side of expressions. But, however powerful and convenient such patterns are, they are not easily composed or, at best, can give rise to complex, nested match clauses that get ugly. So, having a specific application in mind for a more composable set of matchers, I set out to create a library of composable matchers which you can find at Matchers. Robin Hillyard (@Phasm1d)

Writing an Interpreter From Scratch We’ll focus on what compilers and interpreters have in common: lexing and parsing the input. Sakib Hadžiavdić (@sake_92)

Destroy your foldLeft with traverse and State - Scala tutorial In this video, I show how you can tame the complexity of an untamed foldLeft by replacing it with a traverse. Jakub Kozłowski (@kubukoz)

Part 2 - ZIO[_, _, Success] - Getting Started with ZIO in Scala3 In this video we will start implementing our own version of ZIO in order to implement a hello world ZIO application. This video focuses on the third parameter slot (the success channel) of ZIO. DevInsideYou (@DevInsideYou)

Scala with ZIO: Introduction to Fibers This video is a quick dive into ZIO and the effect pattern. We're going to model synchronous and asynchronous computations on top of lightweight threads, aka fibers. Daniel Ciocîrlan (@rockthejvm)
