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.

Hermit is a hermetic and reproducible sandbox for running programs
That's been my experience as well. It lacks support for certain clone(2) flags like CLONE_VFORK[1], which limits the set of non-trivial programs it can run, and since running non-trivial programs is most of the point, I haven't revisited it since it was first announced.

So you think you want to write a deterministic hypervisor?
A Meta developer responded to an issue of mine on Hermit, and said:
"Just to let you know we're not actively working on Hermit in the team..."

Is Something Bugging You?
I really like antithesis' approach: it's non-intrusive as all the changes are on a VM so one can run deterministic simulation without changing their code. It's also technically challenging, as making a VM suitable for deterministic simulation is not an easy feat.
On a side, I was wondering how this approach compares to Meta's Hermit(https://github.com/facebookexperimental/hermit), which is a deterministic Linux instead of a VM.

Deterministic Linux for Controlled Testing and Software Bug-Finding
> AMA!
Eager to try it but encountering the build error here - https://github.com/facebookexperimental/hermit/issues/11
Do you have a reference build log / environment you can share? Last known good commit sha and/or output from "rustup show"?

strace feels like magic — let’s fix that (with Rust)
By the way Facebook has a nice library/system for creating neat observability tools using a small amount of rust: https://github.com/facebookexperimental/reverie.

Show HN: boxxy – Control where Linux programs put files, without symlinks
For a structured approach to ptrace/syscall rewriting, you could try FB's reverie. I worked on and used it during an internship a few years back; it's pretty amazing at what it does.

Deterministic Linux for Controlled Testing and Software Bug-Finding
Note that this is a follow-on project from the earlier Dettrace system, which was applied mainly to reproducible builds (as in the academic paper, https://dl.acm.org/doi/10.1145/3373376.3378519, and presented to the Debian Reproducible Builds summit):
- https://github.com/dettrace/dettrace
And one cool part of it is this Rust program instrumentation layer:
- https://github.com/facebookexperimental/reverie
It's good for building OS-emulator style projects or tracing tools.
What are some alternatives?
sapling - A Scalable, User-Friendly Source Control System.
dettrace - A determinizing tracer using Ptrace
stabilizer - Stabilizer: Rigorous Performance Evaluation
Electron - :electron: Build cross-platform desktop apps with JavaScript, HTML, and CSS
boxxy - boxxy puts bad Linux applications in a box with only their files.
