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: What Are You Working On?
What the hell, here are a bunch of half-baked ideas that I haven't made time for because I'm lazy and stressed out and exhausted:
1. Designing a protocol and air interface for an amateur radio cellular network. This started out with some spread spectrum experiments and an interest in low-probability-of-intercept (below the noise floor) communication. The idea I have now is sort of a cross between APRS and DMR using modern modulation techniques. The network would consist of amateur rooftop "cells" with internet connections, and mobile transponders that communicate with those cells. There'd be some sort of callsign or key based addressing scheme and IP-like network topology discovery. Everything will be authenticated. I'd love to have an encrypted mode, but unless the laws change, it probably isn't going to happen.
2. Open-source firmware or gateware implementation of a USB PD controller that supports entering/exiting alternate modes properly. Inspired by Kate Temkin's Luna project [1]. I got the impression that PD was out of scope for LUNA, at least for the time being, but it would be really nice to have both a USB and PD stack that could be integrated onto a small, inexpensive chip without the proprietary mess.

Sweet, I'll have to give that a go :)
Another option in browser land is lips[0], which exclusively targets a js backend.

All Web frontend lisp projects
For Scheme implementations there are LIPS and biwascheme. I haven't done more than play around with them, so I can't really give an informed opinion about pros and cons or favorites.

Extending a Language — Writing Powerful Macros in Scheme
Your example revealed a bug in my Scheme interpreter. This is an example that fails to match:
-
What other Scheme parser tricks do you know?
In my interpreter, LIPS Scheme, vector literal syntax is created using a syntax extension, a token that is mapped to a function or a macro. So you can use things like this:
-
How to list defined symbols?
I'm not sure about other Scheme interpreters but in my interpreter LIPS Scheme, there is (env) function that returns a list of symbols. You can also access environment objects e.g. (current-environment) return object that is used internally. And you can even access the scope chain because the env object has __parent__ property that returns the parent scope.

Async / Await in Scheme
(define promise (--> '>(fetch "https://lips.js.org/") (then (lambda (res) (res.text))) (then (lambda (text) (. (text.match #/\s*([^>]+?)\s*<\/h1>/) 1)))))

Yes we are men. Men is what we are.
ngl when I first saw the headline my first thought was, “Wait, bring CAR into JavaScript? Make it a Lisp? But hasn't it already been done?”

If you were hired to create a new distribution of Lisp, what would you include?
Languages like Biwa Scheme and LIPS Scheme are good for running Scheme in the browser. But I would prefer compiling Scheme code to JavaScript in the server, then serving the compiled JavaScript image to the browser.
What are some alternatives?
