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.

What if null was an Object in Java?
Fortunately, Uber made tooling for languages with broken type systems

My Thoughts on “Bad Code”
Some patterns arise from language design
* You can't express `T` where `null` is forbidden in the type system so you get NullPointerException everywhere and defensive null checks.
* You express a sum type as a product type because your language does not have sum types .
* Your language doesn't have first class multiple return values (or tuples) so you return extra parameters via out parameters or thread local variables such as `errno`.
* Your language doesn't have exceptions (or algebraic effects) and can't do IO so you have monad transformers.
* Your language doesn't have set-theoretic types so you need hacks like `thiserror` .
* Your language doesn't have stackful coroutines or can't infer async IO for you so you have `async/await` spam or callback hell or "mono's".
* Your language doesn't have exhaustive checks (or pattern matching) so you need a fallthrough case check on switch statements .
* Your language doesn't have algebraic effects, so you need to pass context everywhere.
I know someone will reply about Java's null annotation checking options, so here is one of them: https://github.com/uber/NullAway .

Will Project Valhalla bring Kotlin-like nulls to Java?
If you must use Java, use Uber's Nullaway which gives null safety via Errorprone.

Does anyone have experience using this at Meta who can compare to https://github.com/uber/NullAway ?

How to use Java Records
A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:

Kotlin and Azure Functions - Automating the deployment
Being somewhat allergic to coding in Java (this is a personal thing, if you like Java then good for you) I decided to try out writing the code using Kotlin from JetBrains instead. I'm already using IntelliJ as I work with Apache Spark using Scala, so the tooling was already there and ready to go for this.

Regarding Lenses, Prisms and Optics
Another option could be to check out Kotlin. It's a JVM language that while still object-oriented has may functional syntax features.
