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.

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!
- Mystery? Of the few 1968 Honeywell Kitchen (Pedestal )Computers built, where are they now?

Winner of the lookalike contest
You can get emulators for the machine: SIMH

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.

Zork compiled from MDL source code
A long time ago you posted a suggestion in the original SIMH GitHub as an issue to have Interlan NI1010A added. https://github.com/simh/simh/issues/380

Rust Support Is Being Built into the GNU GCC Compiler
We have `cargo-gccrs` for this, so a cargo subcommand which intercepts arguments given to `rustc` and converts them into `gccrs` arguments :)
https://github.com/rust-GCC/cargo-gccrs/
it's still in a relatively early stage as we are focusing on the compiler. But the idea is for it to be a drop-in replacement for compilation and execution operations, so you'd have `cargo gccrs build`, `cargo gccrs run`, `cargo gccrs test`, etc

GCC gets a new frontend for Rust
gccrs is the compiler (like rustc). You can use cargo with gccrs : https://github.com/Rust-GCC/cargo-gccrs

GCC Rust front-end approved by GCC Steering Committee
See https://github.com/Rust-GCC/cargo-gccrs. There will definetly some sort of cargo support in the end. Either by having a behave-like-rustc wrapper around gccrs or by adding support directly to cargo or a cargo fork.

GCC Rust Approved by GCC Steering Committee
Cargo support for gccrs is part of this project:
https://github.com/Rust-GCC/cargo-gccrs
Moreover, modules are less interesting to me in embedded development as is access to Rust's borrow checker for gaining certainty of small portions of larger projects, which are written in other languages.

GCC Rust in 2021
- With the [cargo-gccrs](https://github.com/Rust-GCC/cargo-gccrs/) we want to integrate gccrs as seamless as possible into the Rust ecosystem. So yes.
