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.

A Tour of Lisps
> The problem with learning Lisp is `(a ,b c)
If you can understand "String ${interpolation}", you can understand list quasiquoting.
> But the problem remains: it only takes one wizard to make reading code impossible by outsiders.
This really is a Lisp meme. There are plenty of Lisp wizards like Guy Steele, Rich Hickey, and Matthew Flatt. The wizards perform the magical act of making code legible and intelligible. I have stumbled around several Clojure and Racket code bases and never felt like "I should understand this code but the features of Lisp make it impossible to know for sure." "Infinite power" macros and whatever are really only used sparingly and generally when it's impossible to achieve a goal otherwise. No one is doing (define + -).
> But this means no-one outside of the language/system developers know the language, this means Lisp tends to be write-only by design - not in the line-noise meaning, but in the obscure foreign language meaning.
I, as a Racket novice, have been able to add candlesticks [1] to the plot library without learning much about it. I have also debugged DrRacket (an IDE) to uncover that Racket GUI operations performed significantly worse if non-integer scaling was used [2]. At no point when I was going through Racket internal code did I ever feel it was write-only. In fact, it was quite convenient to modify Racket internal source code, rebuild, and test changes in a way that would be much more difficult in Java or C++.
> You certainly can not do that, but if you choose to not do that, why pick Lisp?
Built in rationals.
The ergonomics of defining [XML / JSON / etc] data as S-expressions and doing things like pattern matching on that data.
Great, coherent integration between GUIs, plots, statistics functions, and all the other bits of Racket's batteries inclusions.
You still have access to all the other great features that other languages have borrowed from Lisp like REPL development, package managers, good IDE tools, etc.
It is nice to learn the meta-syntax of parentheses once and know that the code will always look like that. No need to consider if some feature is implemented as a syntactically different new keyword, annotation, function call, or whatever. It'll always be a (feature).
> something you have to conciously work for with Lisp.
Plenty of languages have style guides, linters, static analysis tools, etc. to make sure the code conforms to certain restrictions. Lisp feels no different in this regard.

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.
