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.

Ask HN: How to get a job as a compiler engineer?
"attribute grammar" and "novel" in the same statement? Whoa! I tried to publish a paper ~15 years ago on attribute grammars … without success and non-constructive review feedback. I am not aware of any company making use of attribute grammars in production. I had the goal of making use of attribute grammars as part of https://github.com/mozilla-spidermonkey/jsparagus (SmooshMonkey), but making a JavaScript parser generator which is as efficient as our hand-written parser is already surprisingly difficult, and the COVID ended the project.
On the topic of finding a job … I would be of no help. The only internships/jobs I found so far were all outside the usual applications forms:
-
Starlight: JS engine focused on performance in Rust.
Do you know about jsparagus? It's a Mozilla project to rewrite the frontend of their JS engine in Rust.

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.

There's test262_passed file in repo, you can take a look at what tests pass :)
