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.

Why does Racket have Type-Maps instead of Just a Single Map?
See related post. The dot operator in Rhombus will allow a function call like expr.map(…) to be statically specialized to Some.map(expr, …) provided that expr carries sufficient static information. This isn’t possible in Racket given the lack of static information in general.

Multiple namespaces?
Racket has the concept of binding space built on top of the scope-set model. The experiment language Rhombus makes heavy use of this for contextual bindings. Note that bindings are used for language extensions among other purposes in Racket.

Generalized and first-class macros: what is this called?
The notion of “tail sequence” in general doesn’t exist in Lisp’s macro-expansion model, since Lisp macros are strictly local transformations. A “tail sequence” allows a macro to control the expansion of the whole context, which requires wrapping the whole context in another macro in Lisp’s model. This is what leads to proposals like #%local-definition in Racket. However, this notion does exist in the enforestation model, which is what the experiment language Rhombus is based on, although it’s probably not quite a Lisp ;)

Anyone else concerned that Rhombus/Racket2 is not a lisp based language?
Rhombus is: - just another #lang. It is built on top of the existing Racket VM and written in Racket. It interoperates with existing Racket code and uses the Racket expander. - macro extendable. Hygiene and all of the good stuff work. - being developed in the open. We meet biweekly over Zoom, and discussions also occur in GitHub Discussions.
- Anyone aware of Racket projects that are in need of contributors? I am experienced in PL design and have two months worth of spare time. I have never contributed to an opensource project before besides taureg.

Racket->Rhombus: To Sexp or not to Sexp?
Querying Git references for rhombus-prototype at https://github.com/racket/rhombus-prototype.git Using cached16617263581661726358301 for https://github.com/racket/rhombus-prototype.git DrRacket install: version mismatch for dependency for package: https://github.com/racket/rhombus-prototype.git mismatch packages: base (have 8.6, need 8.6.0.9)
Instead of hoping, you might consider reading the discussions to see what the developers are actually saying. Just a thought.

Need recommendation for IPC with Go
py4cl and cl4py rely on uiop:launch-program and python's subprocess respectively. These are portable to the extent uiop and subprocess are portable and do not require any additional installation.

Lisp-Stick on a Python
If you want to use Python libs from CL, see py4cl: https://github.com/bendudson/py4cl the other way around, calling your efficient CL library from Python: https://github.com/marcoheisig/cl4py/ There might be more CL libraries than you think! https://github.com/CodyReichert/awesome-cl (or at least a project sufficiently advanced on your field to join forces ;) )

The German School of Lisp (2011)
FYI you can call Python from CL: https://github.com/bendudson/py4cl and CL from Python: https://github.com/marcoheisig/cl4py/
If you don't know Emacs, see other editors: https://lispcookbook.github.io/cl-cookbook/editor-support.ht... If you want the more Smalltalk-like experience I'd go with the free LispWorks version: it has many GUI panes that allow to watch and discover the state of the program.
I personally couldn't stay long with Hylang. You won't get CL niceties: more language features, performance, standalone binaries, interactive debugger (all the niceties of an image-based development)…

Plotting
I ended up using a fair bit of matplotlib through college and with colleagues. I too don't want to use python, but I also don't like throwing away its libraries, and I'm too lazy to invest in other* plotting ecosystems. In effect, I use up using matplotlib through py4cl/2.

numericals - Performance of NumPy with the goodness of Common Lisp
Note that it is not my aim to replace the python ecosystem; I think that is far too lofy a goal to be of any good. My original intention was to interoperate with python through py4cl/2 or the likes, but felt that one needs a Common Lisp library for "small" operations, while "large" operations can be offloaded to python libraries through py4cl/2.

Good Lisp libraries for math
If performance is absolutely not a concern, then third option is using python libraries through py4cl/2. To put it differently, if calling python from lisp is not the bottleneck, then this is a feasible option.

Why Hy?
I encourage people to try out Common Lisp because, unlike with Hy, you will get: speed, ability to build binaries, truly interactive image-based development (yes, more interactive than ipython), more static type checks, more language features (no closures in Hy last time I checked), language stability… To reach to Python libs, you have https://github.com/bendudson/py4cl My comparison of Python and CL: https://lisp-journey.gitlab.io/pythonvslisp/

(define (uwu) (display "nya~\n"))
Ahh, makes sense. Well, if you ever wanna steal some of python's thunder, libpython-clj worked great for me lol. Supposedly py4cl fills a similar role in Common Lisp.
What are some alternatives?
swi-mqtt-pack - MQTT pack for SWI-Prolog
py4cl2 - Call python from Common Lisp
SmalltalkVimMode - Vim Mode for Playground, System Browser, Debugger in Pharo.
magicl - Matrix Algebra proGrams In Common Lisp.
gerbil - Gerbil Scheme
cl-cuda - Cl-cuda is a library to use NVIDIA CUDA in Common Lisp programs.
sham - A DSL for runtime code generation in racket
hy - A dialect of Lisp that's embedded in Python
racket-mode - Emacs major and minor modes for Racket: edit, REPL, check-syntax, debug, profile, and more.
libpython-clj - Python bindings for Clojure
conjure - Interactive evaluation for Neovim (Clojure, Fennel, Janet, Racket, Hy, MIT Scheme, Guile, Python and more!)
coalton - Coalton is an efficient, statically typed functional programming language that supercharges Common Lisp.
