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.

Favorite hidden gem library?
I really like StreamEx. I do not know why people do not use it often, the syntax is just wonderful.

Jodd – The Unbearable Lightness of Java
It gets more perverse if you need to flatMap, or transmute components of map types, etc. If you want even more power, take a look at https://github.com/amaembo/streamex. This sort of container manipulation bread and butter for business processing. I use it every day, sometimes with a dozen operations. This (with liberal use of `final` values) makes for some pretty functional-looking code.
I'll grant you the Kotlin or Scala version is slightly more compact. But not fundamentally different, like the Go version.
I (and the pretty much every language designer in the post-Java era) disagree with you about checked exceptions, but that's a whole different thread...

Relearning Java Thread Primitives
I’ve coded in Java since the first beta, even back then threads were at the top of my list of favorite features. Java was the first language to introduce thread support in the language itself, it was a controversial decision back then. In the past decade, every language raced to include async/await and even Java had some third-party support for that… But Java zigged instead of zagging and introduced the far superior virtual threads (project Loom). This post isn’t about that.

Managing Cluster Membership with Etcd
Given our new functionality to update the membership list, we can create a new test case where two nodes join the cluster and expect that to be reflected in the local state of each node eventually. Thanks to the Awaitility DSL we can conveniently wait for the eventual update to happen.

What are some alternatives?
jOOλ - jOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.
