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.

Building a bare-metal Kubernetes cluster on Raspberry Pi
https://github.com/kraken-hpc/kraken
Kraken is a state engine. In the case of the Pi cluster it would work to provide network images, install and configure nodes, reboot nodes, and manipulate their state as needed to keep things running.
Another fun piece of research on Pis out of LANL is that at their altitude, 7000ft, they estimate that on average a Raspberry Pi will crash once every 2 years due to bit flips caused by cosmic rays.

μMon: Stupid simple monitoring
You can easily put together something that will send UDP packets with stats at regular intervals. I’ve done that a number of times - https://github.com/rcarmo/raspi-cluster/blob/master/tools/se...

Building a bare-metal Kubernetes cluster on Raspberry Pi
I like the trays. Back when I rebuilt mine from Pi 1Bs to 2Bs* I printed a vertical holder where the Pi itself was the slottable unit, but if I were to rebuild mine today I'd print some trays and use an existing box.
One thing that I did that might make sense for that setup was that my master has a Wi-Fi dongle and performs NAT/DHCP for the other Pis - this makes it easier to do a lot of stuff, including auto-configuration.
