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.

Adding keys to the firmware
However, I found out on the nsacyber github repo that setting secure boot configuration to none, sets secure boot to setup mode, for the next boot.

Can a laptop from 2012 be a viable home server?
OpenBSD will disable all but the first thread on any Intel processor by default. I'm assuming that these models are too old to have microcode updates addressing the Spectre exploits (Meltdown, Foreshadow, Fallout, Zombieload, RIDL etc.), and disabling SMT/HT might be the most secure thing to do by default.
This script produces a good assessment of Spectre problems for a wide variety of CPUs. I know that they are difficult to exploit, and the mitigations are disabled by many because of their performance impact.

Any opinion about NUC as home server?
He's probably referring to the class of vulnerabilities checked by this script: https://github.com/speed47/spectre-meltdown-checker. It's not just Intel CPUs that were affected, AMD and ARM also have some vulnerabilities (I just ran it on an ARM v7 to see) although maybe not as many.
