Build Great Native CLI Apps in Java with Graalvm and Picocli
Compared to other choices, Java is not that convenient for creating simple command-line driven apps - largely due to the need to distribute a sizable runtime. The combination of GraalVM and Picocli aims to change that, by providing native compilation alongside an easy, modern way to handle command-line args.

A Bottom-Up View of Kotlin Coroutines
Recently coroutines have become popular as an alternative to Reactive Programming on the JVM. In many cases the costs of restructuring your code around functional operations for reactive streams outweigh the benefits, so coroutines have emerged, initially for Android, as an alternative solution. This deep dive explores how Kotlin's implementation works under the hood.
