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.

Spring Modulith: have we reached modularity maturity?
Spring Modulith is the successor of Oliver Drotbohm's Moduliths project (with a trailing S). It uses both ArchUnit and jMolecules. At the time of this writing, it's experimental.

Deprecating JPA no-args constructors
You could move towards modeling your code around DDD building blocks (like aggregates etc.) and declare those concepts in code explicitly using jMolecules types. There is a dedicated jMolecules Integrations ByteBuddy Plugin, that would then add the necessary boilerplate code and default mappings required by the expressed concept. This makes the code shown here a fully working JPA model. You can argue that the lack of JPA oddities is odd itself in the first place but I like the idea of expressing the architectural concept explicitly and the technology integration completely flowing from that.

Ask HN: Guidelines for making clear architecture diagrams
Second this.
Reference for anyone looking I to it: https://c4model.com/
There is also quite a lot of options for helping create these diagrams. I've found https://structurizr.com/ to be the best of what I've tried so far.

Ask HN: How do you document complex software systems?
The C4 model [0] provides a mostly sensible structure and techniques for representing pure software systems across different abstraction levels.
For systems involving software and hardware, or other complex interfacing (both technology and bureaucracy) this starts to delve into the universe of systems engineering. There's a decent assembly of knowledge on that in the SEBoK [1].
As another commenter has already called out too, one of the most valuable sources of information is also _why_ a system is in its current form and _how_ that's changed over time. ADR's [2] really do a good job at nailing this for just about any scale.

A View on Functional Software Architecture
There a various standards for documenting software architecture, like arc42 or C4. While useful and somewhat well-known (there is certainly a correlation here), here architecture documentation can be further simplified, particularly due to the self-similarity of project and component. Following is a small template, that can also serve as a project's and component's README:

Inkscape Cloud Architect
I would suggest that if your architecture diagrams are a bunch of icons provided by AWS/Azure/GCP with lines pointing at each other... you are doing it wrong.
The 'what does this box do for my system' is vastly more important than the 'which in vogue offering from my cloud provider implements it'.
I highly suggest folks take a look at the C4 Model: https://c4model.com/

How to create interactive zoomable software architecture diagrams
We often use abstractions in software engineering to communicate complex architectures and software systems. In this article, we’ll discuss how abstractions are inherently hierarchical and how the C4 model provides a nested structure for defining your software architecture. We’ll then cover how IcePanel allows you to create interactive and zoomable diagrams for your audience to zoom in and out of different levels of technical detail.
