Death of Blocker: blocking in Cats Effect 3 - Scala tutorial

Jakub Kozłowski explains how to migrate from Blocker in Cats Effect 2 to the new blocking mechanisms in Cats Effect 3.

A flashback to the first video I published (Blocker in Cats Effect 1.4.0). In this one, you'll learn how to migrate from using Blocker in Cats Effect 1/2, and how blocking is done in Cats Effect 3. You'll also see other new things in the library, like interruptible blocking and IOApp.Simple.
