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.

eBPF – Running sandboxed programs in a privileged context such as OS kernel
This is a good write-up and I like the diagrams. What appears to still be missing in an "off switch". AFAIK there are still no kernel boot time commands to disable eBPF entirely. I have to recompile the kernel to disable it.
eBPF has the potential for file-less malware to run hidden from detection and I foresee the ability to tickle ring -3 (and -4?) CPU within CPU functions while bypassing local firewalls.
Here is some example code of what people already know how to do today and this list will grow as people discover more capabilities. [1][2][3][4][5] These do require some privileges to insert but will remain running and hidden until reboot.
