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.

Use Tetragon to Limit Network Usage for a set of Binary
Many interesting software are coming from the community, many are distributed through the package manager of the operating system. But for the others, you can download them from Github release pages, use snap or homebrew to cite a few. But this last installation method bypasses the security team that tries to improve the security of your operating system. By doing so, you are implicitly trusting the author he is not distributing malware or implementing backdoors. How many tools did you install by hand? Do you really trust all of them? Confidence is very important, yet it would be nice to limit capabilities for a set of binary that you don't fully trust. In this blog post, we will use Tetragon to forbid network usage for tools that don't need to.

Implement DevSecOps to Secure your CI/CD pipeline
Falco is a cloud native Kubernetes threat detection tool. It can detect unexpected behavior, intrusions, and data theft in real time. In the backend, it uses Linux eBPF technology to trace your system and applications at runtime. For example, it can detect if someone tries to read a secret file inside a container, access a pod as a root user, etc, and trigger a webhook or send logs to the monitoring system. There are similar tools like Tetragon, KubeArmor, and Tracee which also provide Kubernetes runtime security.

Murmur3 hash plugin for nested objects?
I don't think the murmur3 hash implementation has changed since it was added as the default in version 2.0 (see the [changes](https://github.com/elastic/elasticsearch/commits/main/server/src/main/java/org/elasticsearch/cluster/routing/Murmur3HashFunction.java)). The plugin itself has seen [more changes](https://github.com/elastic/elasticsearch/commits/main/plugins/mapper-murmur3) but that's IMO because of internals and not visible changes in the calculations.

Mongo or Mysql for 10tb of JSON documents, I'm questioning my previous choice.
Mysql is not as open source as postgres (long story). And you can see how open elasticsearch is by just having access to the bugs database https://github.com/elastic/elasticsearch/issue
