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.

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:

How do you integrate a static security analysis tool into the CI/CD pipeline
There are commercial tools that can be integrated into a CI pipeline and/or a developer's IDE. I've used SonarQube before, but there are others.

Technical Debt: Lessons from 10 Years of Change
But back in 2012, tech debt-related tools were in their infancy. JetBrains released IntelliJ IDEA in 2000, and SonarQube was initially released in 2006. Stepsize started in 2015, and Visual studio intellicode wasn't made by Microsoft until 2018.

Spring Boot – Black Box Testing
The generated classes should be put into .gitignore. Otherwise, if you have Checkstyle, PMD, or SonarQube in your project, then generated classes can violate some rules. Besides, if you don't put them into .gitignore, then each pull request might become huge due to the fact that even a slightest fix can lead to lots of changes in the generated classes.
What are some alternatives?
Error Prone - Catch common Java mistakes as compile-time errors
Spotbugs - SpotBugs is FindBugs' successor. A tool for static analysis to look for bugs in Java code.
infer - A static analyzer for Java, C, C++, and Objective-C
Checkstyle - Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. By default it supports the Google Java Style Guide and Sun Code Conventions, but is highly configurable. It can be invoked with an ANT task and a command line program.
FindBugs - The new home of the FindBugs project
PMD - An extensible multilanguage static code analyzer.
semgrep - Lightweight static analysis for many languages. Find bug variants with patterns that look like source code.
jQAssistant - Your Software. Your Structures. Your Rules.
snyk - Snyk CLI scans and monitors your projects for security vulnerabilities. [Moved to: https://github.com/snyk/cli]
