Learn how to convert Java to Kotlin by following Kotlin's idioms with Google Developers Codelabs. Refactoring to Kotlin, which is available in English, Brazilian and Chinese, provides a guided, hands-on coding experience in a running time of just less than an hour.

While the latest IDE's do a good job in automatically converting Java code into Kotlin, this doesn't preclude that you also understood the mapping from the one code base to the other.Further you are naturally predisposed to continue writing Kotlin under Java's mentality, following Java's practices and idioms.

The book opens by putting things into perspective in Chapter 1: Motivation: why do you want to build lan…

Machine Learning Applied to Game of Thrones

No-one wants the beloved series to end. Some, like the geeks at Pachyderm, have gone to great lengths to extend its life span, to the point of employing ML to serve the Iron Throne.  This is a new example of style transfer where ML identifies the essential characteristics of a genre in order to create its own examples, such as we've seen before with art  and even with cooking. But first of all, what is Pachyderm and where does that word come from?
