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.

MongoDB is actively investigating a security incident
aphyr seems to still work on it, so probably just not that many companies who want to pay to get told the truth anymore: https://github.com/jepsen-io/jepsen

What Is Property Based Testing?

ZooKeeper-free Kafka is out. First Demo
https://github.com/jepsen-io/jepsen/issues/399
> Yeah! I mean, I find a lot of linearizability errors in various databases, but this was also my very first time doing this kind of test, and it varies from system to system. Could have easily slipped through the cracks.
In summary, aphyr thought Zookeeper is linearizable even though it doesn't provide linearizable ops.
Looks like Zookeeper needs to be tested again.

Help me identify this design pattern
Spring does this during autoconfiguration. For example this and this. When the user adds a configuration then it gets to overwrite the default from the template. I am looking for something similar, perhaps simpler approach.

A simple file source/sink connector?
Code is still in trunk though. https://github.com/apache/kafka/tree/trunk/connect/file/src/main/java/org/apache/kafka/connect/file

Can someone please eli5 how the hierarchical timing wheel algorithm works?
I briefly described the algorithm in this article and there is a wonderful article from Kafka that goes into more depth in their general purpose implementation. My implementation is specialized and over optimized in comparison, e.g. by using bit manipulation to avoid more expensive division/modulus instructions. Tokio rewrote their timerwheel after I showed them mine, borrowing some ideas but also staying more general. Hope that helps!
