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.

Go, Containers, and the Linux Scheduler
We use https://github.com/uber-go/automaxprocs after we joyfully discovered that Go assumed we had the entire cluster's cpu count on any particular pod. Made for some very strange performance characteristics in scheduling goroutines.

Setting GOMAXPROCS without CPU limits in Kubernetes?
Please never set the value manually in a kubernetes production environment. Use https://github.com/uber-go/automaxprocs
-
What are goroutines and how are they scheduled?
There is an environment variable (GOMAXPROCS) that you can set which determines how many threads your go program will use simultaneously. You can use this great library from Uber to automatically set the GOMAXPROCS variable to match a Linux container CPU quota. If you are running Go workloads in Kubernetes, you should use this.

Shouldn't have happened: A vulnerability postmortem
AFAIK, it hasn't changed, this exact situation with cgroups is still something I have to tell fellow developers about. Some of them have started using [automaxprocs] to automatically detect and set.
