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.

Building a Minimalistic Virtual Machine
If you want to compute like it's 1986, I think it would be fun to build a BASIC interpreter for UVM. Bonus points if you do your own text rendering on a blue background and you add simple primitives for 2D graphics.

gc-shadowstack: Implementation of shadow stack algorithm to track GC rooted objects.
Hello to all! This crate implements Shadow Stack algorithm which allows to track GC objects on stack with almost zero overhead! This algorithm is used inside Restricted Python and seems to work very well. This crate soon will replace DIY shadow stack implementation in starlight(JS engine in Rust) too.

March 2021 monthly "What are you working on?" thread
Working on startup snapshots in starlight. I already have very basic implementation which allows to initialize runtime in just 17 microseconds from snapshot vs 23 microseconds without snapshot when every builtin is created from scratch. Future work is aimed mostly on making deserialization faster

Reference counting GC vs tracing GC and JITs
Hi to all! I'm working on starlight (JS engine in Rust) and I can't choose memory management technique: Right now I have conservative on stack precise on heap GC which somehow manages to work but still has segfaults and I'm also working on rcgc feature which will use RC as GC algorithm but my main question: is it worth using RC over tracing cycle and how hard it will be to implement JIT when RC is used? I've never seen any runtimes that use RC and implement JIT.

Starlight: JS engine focused on performance in Rust.
There's test262_passed file in repo, you can take a look at what tests pass :)
