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.

The Emacsen family, the design of an Emacs and the importance of Lisp (2023)
Two projects that may be of interest, related to this topic:
- Rune (https://github.com/CeleritasCelery/rune) - A re-implementation of Emacs but in Rust (like Remacs, but actively developed)
- Pimacs (https://github.com/federicotdn/pimacs) - Same, but using Go (created by me, but developed in a very slow pace)

Design of Emacs in Rust

Implementing a safe garbage collector in Rust
> How is anything rooted here? The lifetime changed from 'arena to 'root but I don't see a root being created.
In this example, the Vec has been rooted previously. So pushing an object into the Vec will make it "transitively" rooted (accessible from the root). You would root a struct with the root_struct![1] macro, which works very similar to the root! macro shown in the post.
However you made you realize one error; The rooted `Vec` in the example you pointed is a by value type, but in the implementation you can only get references to rooted structs, so that example needs to be updated.
> But later we see roots not obeying a LIFO order, under "Preventing escapes" where roots are dynamically created and destroyed in an arbitrary order.
Objects are just a copyable wrapper around a pointer, so they are not the part that has the LIFO semantics. inside the root! macro[2] there is a `StackRoot` type that is the actual "root". The object just borrows from that so that is has a 'root lifetime and is valid post gc. The actual root struct is not exposed outside of the macro.
I hope this makes the distinction between "roots" and "objects" clearer. Objects are just pointers to heap data. When we root an object we store the data it points to on the root stack and create a new `StackRoot`. Then we say this object is rooted. But the struct that "does the rooting" is inside the macro and not exposed. Rooting a struct works similarly.

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.
