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.

Retrofitting null-safety onto Java at Meta
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:

What are some useful static analyzers for Java?
SpotBugs have a lot of extensions such as https://find-sec-bugs.github.io/ https://github.com/KengoTODA/findbugs-slf4j and more, I recommend adding them as well

Looking for a Static Code Analysis tool for Scala Code
If you don’t have checkmarx/Vera code money, have you looked at https://find-sec-bugs.github.io/? It can be used with a few things such as https://spotbugs.github.io/ and sonarQ

Conducting SAST for Java Applications
How can the article fail to mention Find Security Bugs (find-sec-bugs) when talking about using SpotBugs (ex-FindBugs) for analyzing code for security issues?

Design an Effective Build Stage for Continuous Integration
Find Security Bugs uses a security database to detect almost 140 different vulnerability types in Java web applications.

ShellCheck: A static analysis tool for shell scripts
find-sec-bugs does that. It's used by, for example, SonarQube.
See hhttps://github.com/find-sec-bugs/find-sec-bugs/blob/master/f... and do a "CTRL-F" and search for "References".
What are some alternatives?
SonarQube - Continuous Inspection
Spotbugs - SpotBugs is FindBugs' successor. A tool for static analysis to look for bugs in Java code.
Error Prone - Catch common Java mistakes as compile-time errors
semgrep-rules - Semgrep rules registry
infer - A static analyzer for Java, C, C++, and Objective-C
snyk - Snyk CLI scans and monitors your projects for security vulnerabilities. [Moved to: https://github.com/snyk/cli]
semgrep - Lightweight static analysis for many languages. Find bug variants with patterns that look like source code.
FindBugs - The new home of the FindBugs project
static-analysis - ⚙️ A curated list of static analysis (SAST) tools and linters for all programming languages, config files, build tools, and more. The focus is on tools which improve code quality.
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.
