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.

Finally, the kotlin API and External Cache are supported, and my ORM is finished.
A medium project for Java and Kotlin developers: https://github.com/babyfish-ct/jimmer.
-
A benchmark to show you how fast my ORM framework is
If you want to run the benchmark, run this project please.
- A powerful java framework for immutable data and ORM based on immutable data
- I ported my kotlin framework "kimmer" to java, named "jimmer"
-
The problems of java record and my solution.
I thought hard about this problem and ported an industry-leading solution to Java. But the original article is long, please click here: https://github.com/babyfish-ct/jimmer/blob/main/doc/jimmer-core/README.md

Record Patterns point to Java language designers losing their compass
Record patterns are one step on the path to general pattern matching utility. The bigger building block is general deconstructors. I recommend reading Functional Transformation of Immutable Objects by Brian Goetz. The idea of "withers" shown there requires deconstructors:

This is the vague plan.

Where does the dislike/hate for Java come from?
This kind of pattern matching is discussed in the design notes: https://github.com/openjdk/amber-docs/blob/master/site/design-notes/patterns/pattern-match-object-model.md

Making Lenses Practical in Java
True, but that only pushes the question of value down the line.
I'm curious about lenses because Java did have a serious problem that required a solution: working with "simple" data correctly was difficult. The chosen solution was ADTs, so we did buy into that. But the approach being explored for transforming records (https://github.com/openjdk/amber-docs/blob/master/eg-drafts/...) only works one level at a time rather than for an entire path. So I wonder how valuable it would be to have a solution for paths. If the answer is that it's mostly valuable for an approach we haven't bought into yet, then we might not need to consider it just yet.

How I got involved in the Rust community
Just a heads up, something like that spread operator is actually coming sooner or later to java: https://github.com/openjdk/amber-docs/blob/master/eg-drafts/...
Pattern matching (for records) is already a preview feature.
