Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Project Valhalla: A look inside Java's epic refactor
Nice. So for example, it looks like Kotlin has a nearly identical feature at the language level which will be optimizable when Valhalla ships: https://github.com/Kotlin/KEEP/blob/master/notes/value-class...
> In the future, in a Valhalla-capable JVM, JVM primitive classes will enable efficient representation of Kotlin value classes with an arbitrary number of underlying fields on JVM.

Unchecked Java: Say Goodbye to Checked Exceptions Forever
Most other languages agree that checked exceptions are not good by not having them.
As for alternatives, Try/Result and similar monads have decent adoption even in Java, but personally I quite like the Kotlin philosophy [1] to not have generic error containers and either use runtime exceptions or make failures of the return type.

Why should I use kotlinx.serialization?
Kotlin multiplatform types often come with their own serializers. https://github.com/Kotlin/kotlinx-datetime and https://github.com/hfhbd/kotlinx-uuid do, for example.

What's the best way to calculate the number of days between two dates in Kotlin?
It depends, time has a complex and native bound legacy. But I bet you want this https://github.com/Kotlin/kotlinx-datetime and DateTimePeriod.
