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.

Integral Calculator
Compile ITS and just run :macsyma at the DDT prompt (shell/debugger) from ITS:

The syntax it's the same, I even made a plot and 'printed' into the host from an ARDS output from the plot command, by converting the file into PPM->PNG or PPM->PDF.

ITS didn't really have password control, one was technically added but IIRC it was a fig leaf on some requirement from outside MIT. The user accounts were there mostly to inform others who was logged on and who owned what process.
You could login either using terminal through ARPAnet dial-in support, or later over network, and over time there was added a more concrete "tourist" policy.
DonHopkins seems to have an interesting writeup https://donhopkins.medium.com/mit-ai-lab-tourist-policy-f73b...
and of course there's PDP-10 org and its gather docs on github: https://github.com/PDP-10/its
