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:
https://github.com/pdp-10/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.

Research Unix Sixth Edition (WASM)
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

SIMH – Old Computer Emulator
It sounds like there was a config option available to disable the signature addition to the image file ( https://github.com/simh/simh/issues/1059#issuecomment-108689... ). I could see a benefits for having an embedded image signature for preservation and corruption detection issues.
I don't think complaining about the design is toxic, but recruiting uninvolved people on twitter, and harassing out of ban certainly is. Also reading the bug thread it seems the person with the issue wasn't the same as the one who instigated the harasment. (https://github.com/simh/simh/issues/1059#issuecomment-108675...)

Multics Simulator
Perhaps, however, SIMH (http://simh.trailing-edge.com/, https://opensimh.org/) also calls itself a simulator rather than an emulator. Six of one, half dozen of the other, I guess!

Anyone know how to attach a network device to a simulated VAX in simh?
I looked into this recently too, given the large amount of instructions at https://github.com/simh/simh/blob/master/0readme_ethernet.txt I decided it was too much bother for now.

Pico_1140: A PDP11/40 emulator that will run Unix v5/v6 on a Raspberry Pi Pico
In case anyone was wondering:
> The de facto emulator for most old computers is Simh https://github.com/simh/simh. The size and complexity of the individual machine apps is such that a direct port to a memory limited system is not feasible.

GCC gets a new frontend for Rust
VAX has its die hard fans, and the historical value of the VAX and what it did to shape our computing world can't be overstated. As both a learning tool and a way to preserve history, simh and VAX emulation are wonderfully accessible. VAX running modern NetBSD does an excellent job illustrating where performance regressions happen and where bad assumptions are made. None of these are compelling reasons to target a new toolchain to a classic architecture by themselves, but the interest is there.
