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.

How to Check if a Java Project Depends on A Vulnerable Version of Log4j
The team at FullHunt provided an open-source tool called log4j-scan, an automated and extensive scanner for finding vulnerable Log4j hosts. It allows teams to scan their infrastructure but also test for WAF (Web Application Firewall) bypasses that can result in code execution. The tool has several options but in short, you pass to the tool the URL to scan and you get a report on the vulnerabilities found. For example:

Hackers exploited Windows 0-day for 6 months after Microsoft knew of it
I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

The Dedicated Maintainers Behind Lesser-Known Open Source Projects
However, there are many open source projects that are widely used but not well-known, including cURL, ImageMagick, MyCLI, Homebrew, Apache Log4j, and OpenSSL. This article will take a closer look at these unsung heroes of the open source world. I do not want to give them a business model or financial advice in this article. This largely depends on the author's personal experience and values. I just want to raise more awareness about these open source projects.

Apache POI Setup Logging Error
What you need is log4j-core, what you downloaded is some kind of connector between log4j and JUL. Tbh I don't know what JUL is, but that's not important. You can get log4j-core on from the official website - https://logging.apache.org/log4j/2.x/ or in maven repo. In case you're not using maven, I highly, highly recommend you using it for managing your dependencies.

Log4Shell Still Has Sting in the Tail
> When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever.
> The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...
Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.
Remember: this vulnerability was disclosed to them in November.
