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.

Let's Write a Malloc
Never forget:

> Let me stress here that while this collector is simple, it isn’t a toy.
> There are a ton of optimizations you can build on top of this—in GCs and programming languages, optimization is 90% of the effort—but the core code here is a legitimate real GC.
> It’s very similar to the collectors that were in Ruby and Lua until recently.
> You can ship production code that uses something exactly like this.
> Now go build something awesome!

loxcraft: a compiler, language server, and online playground for the Lox programming language
Bob Nystrom also has a blog, and his articles are really well written (see his post on Pratt parsers / garbage collectors). I'd also recommend going through the source code for Wren, it shares a lot of code with Lox. Despite the deceptive simplicity of the implementation, it (like Lox) is incredibly fast - it's a great way to learn how to build production grade compilers in general.

The Garbage Collection Handbook, 2nd Edition
Bob Nystrom (of Game Programming Patterns, Crafting Interpreters, and dartfmt fame) also wrote a tutorial[1], of a precise as opposed to a conservative garbage collector.
Regarding register scanning, Andreas Kling has made (or at least quoted) an amusing observation[2] that your C runtime already has a primitive to dump all callee-save registers onto the stack: setjmp(). So all you have to do to scan registers is to put a jmp_buf onto the stack, setjmp() to it, then scan the stack normally starting from its address.

Reference Count, Don't Garbage Collect
To better understand garbage collection, nothing better than implementation. This article is such a joy to read:

Ask HN: Does anyone Lisp without Emacs?
Racket (https://racket-lang.org) has an IDE (DrRacket) which isn't EMACS. ARC (which powers hacker news) is (was?) written in Racket.

Douglas Crockford, author of ‘Javascript: the good parts’ and ‘How Javascript works’ will be giving the keynote presentation From Here To Lambda And Back Again at the thirteenth RacketCon.
Nice! Repeating a comment I just made on HN: I signed up for RacketCon, will be joining remotely. I am looking forward to it a lot. Usually I use the Racket language perhaps for 10% of my personal projects, but I am currently writing a Racket AI book, so all things Racket are of current interest. Past RacketCons have been a lot of fun. I usually use Common Lisp, but Racket is batteries included Scheme, and more, and is a very pleasant language and ecosystem. Just in case you don’t have Racket installed: https://racket-lang.org/

Ask HN: What is the most suitable Scheme implementation to learn today?
I'd suggest Racket (https://racket-lang.org) which is a batteries-included language environment that includes scheme and has a lot of high-quality documentation.
Guile (https://www.gnu.org/software/guile/) isn't quite as learner-focused but is another great choice.

Setting up a Scheme coding environment in VS code?
The Racket fork of CS supports Apple Silicon natively, and can be installed independently: https://github.com/racket/racket/blob/master/racket/src/ChezScheme/BUILDING Chez adds a few features (threads, ffi, ...) to R6RS; there is a useful combined index to TSPL4 and the CS User Guide at http://cisco.github.io/ChezScheme/csug9.5/csug_1.html

Is SICP an overkill for a 14 year old?
If you're using SICP in Scheme (or are you doing the JS version?) then you may want to look at How to Design Programs. It uses Racket which is a Scheme descendent so much of the language you've learned in SICP will work in it without issue. It also has a pretty good set of GUI and drawing capabilities you can find through the Racket docs page and will use some of with HTDP.
