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 Kubernetes computes CPU utilization for HPA?
According to this doc it takes the average of CPU utilization of a pod (average across the last 1 minute) divided by the CPU requested by the pod. Then it computes the arithmetic mean of all the pods' CPU.

Comparing Kubernetes Gateway and Ingress APIs
With the Gateway API being a superset of the Ingress API, it might make sense to consolidate both. Thanks to the SIG Network community, Gateway API is still growing and will soon be production ready.

How to get a head start into contributing to open source projects
Projects in/around Kubernetes and the CNCF are generally where I spend what little time I can these days. Most communities are incredibly welcoming and provide timely feedback. But the problem space of "managing a cloud platform" can take several years to really wrap ones head around, setting aside focused topics via SIGs like networking, storage, observability, API design, etc.

Getting started with kubectl plugins
Krew is a plugin manager maintained by the Kubernetes Special Interest Group (SIG) CLI community. Krew makes it easy to use kubectl plugins and helps you discover, install, and manage them on your machine. It is similar to tools like apt, dnf, or brew. Today, over 200 kubectl plugins are available on Krew - and that number is only increasing. Some projects are actively used and some get deprecated over time, but are still accessible via Krew.
