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.

Just Say No
Maybe (most likely) this is a problem of GitHub's terminology. For genuine bugs, e.g. here's the repro, the stack trace, the code to replicate it, it happens 100% of the time if you follow these steps, I'd agree that just having it open and in the backlog would be preferable.
The problem is those make up maybe at a generous estimate, 10-15% of issues in a projects backlog. In the interests of full disclosure here's mine (I don't use stalebot) https://github.com/UglyToad/PdfPig/issues?page=1&q=is%3Aissu.... As you can see from the backlog I close almost nothing. This was a deliberate choice to avoid closing things until the fix was confirmed by the reporter.
But equally that's the first time I've opened the repository in a couple of months and the amount of angst and dread I feel just from the size of that list means I'll probably find yet another excuse not to do anything on it this coming month.
Discussions on this topic feel a lot like "technical solutions to social problems"; by which I mean "well in the ideal world a perfectly logical person would do x, y, z so the system should reflect that". And while a stalebot is the archetypal technical solution to a social problem it at least works with how maintainers work. Sometimes in life you want to ignore a problem and have it go away. When you can't do that, e.g. government bureaucracy, work stuff, social obligations, that's where stress comes from. And asking volunteer maintainers to add a whole new source of stress in their life falls apart when people get busy, or their life circumstances change, or they get ill or tired or whatever.
Yes, in a perfect world the issue backlog would be sacrosanct and perfectly groomed/prioritized. But we're just fleshy sacks of chemicals and we're not perfect. Unrealistic expectations from users are the cause of maintainer burnout.
Because GitHub closed issues are still viewable and searchable (I'd guess most people search it through a search engine not the terrible inbuilt search) I'd disagree that they're deceiving users somehow.

You could try PdfPig. https://uglytoad.github.io/PdfPig/ I've used it for some small tasks and found it very useful. If you want to handle scanned pdfs you would need to use OCR instead.

Fault Tolerance in Distributed Systems: Strategies and Case Studies
Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service.

Analysing Github Stars - Extracting and analyzing data from Github using Apache NiFi®, Apache Kafka® and Apache Druid®
You can install Kafka from https://kafka.apache.org/quickstart. Because Druid and Kafka both use Apache Zookeeper, I opted to use the Zookeeper deployment that comes with Druid, so didn’t start it with Kafka. Once running, I created two topics for me to post the data into, and for Druid to ingest from:

How to choose the right API Gateway
Next, review deployment complexity such as DB-less versus database-backed deployments. For example, Kong does require running Cassandra or Postgres. Apigee requires Cassandra, Zookeeper, and Postgres to run, while other solutions like Express Gateway and Tyk only require Redis. Apache APISIX uses etcd as its data store, it stores and manages routing-related and plugin-related configurations in etcd in the Data Plane.

ElasticJob 3.0.2 is released including failover optimization, scheduling stability, and Java 19 compatibility
ElasticJob achieves distributed coordination through ZooKeeper. In practical scenarios, users may start multiple jobs in the same project simultaneously, all of which use the same Apache Curator client. There are certain risks due to the nature of ZooKeeper and the callback method of Curator in a single event thread.
