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.

uLisp wireless message display with a Pi Pico W
There is a uLisp Builder that generates platform-specific builds from a single codebase.
> The uLisp Builder is a set of programs written in Common Lisp to allow you to build a version of uLisp for a particular platform from a common repository of source files.
> The aim of the Builder was to make it easier to maintain uLisp across multiple platforms. Where the C function for a particular uLisp feature is identical on all platforms there is just a single occurrence of that source in the Builder repository.

uLisp
I'm a big fan of uLisp, got it running on an ESP8266. Love how the whole language fits in a single file, making it easy to hack around.
Recently I learned how the author generates the uLisp variants for different platforms using Common Lisp:

..And an accompanying article to describe how it works:

Did we lose our way in making efficient software? – ~30 MB doc file vs. browser
It's interesting: minimal software is out there, but folks don't tend to choose it. I spend a fair amount of time thinking about how to be conservative in my dependencies, and this encourages a lightweight stack that tends to perform pretty well. These days, I'm favoring tools like Lua, SQLite, Fennel[0], Althttpd[1], Fossil[2], and the Mako Server[3] and find that great, lightweight, stable, efficient software is to be had, for free, but you have to go a bit off the beaten path. This isn't stuff you hear about on Stack Overflow.
In terms of frontend, which the post focuses on (Google Docs and a 30MB doc), I guess I'm conflicted. While I tend to favor native apps + web pages, I'm also a daily Tiddlywiki user, and I really think web apps have their place (heck, one idea I'm working on is a lightweight local server that lets you run web apps like Tiddlywiki). But without a doubt, Tiddlywiki is more resource intensive than Emacs (my go-to for notetaking when I'm not on TW). My tab for a 6MB Tiddlywiki file uses 155MB of RAM, and my (heavily customized, dozens of open buffers) Emacs session uses 88MB. So I do think the author has a good point.

Pluto, a Modern Lua Dialect
Eh it's not just luajit and luajit didn't create that problem either. It's a symptom of lua actually succeeding at its design goal of being easily embedded as an extension language. A significant number of incompatible runtimes are more popular than the most recent puc lua, including I believe the older official lua 5.2 released in 2011.
I've done a fair bit of professional lua development and I don't think I've ever written standalone up-to-date puc lua except maybe for some tooling & scripts. It's such a small language and used in such a way that the runtime, distribution method, and available APIs have much more impact on your use (and compatibility) than the version.
Virtually everyone shipping a lua environment is also shipping changes to it that make it a unique target, if only extensions to the standard library. This is why I think syntax layer-only approach like fennel's is the correct choice for improving on lua. It mirrors lua's runtime semantics exactly, and allows you to access the implementation peculiars on their own terms and so can just be run on time of any lua system.

LÖVE: a framework to make 2D games in Lua
Just learned about https://fennel-lang.org/ , could have probably used that as well to avoid Lua.

The Bipolar Lisp Programmer
> I’m positive that there is a Lispy language out there (actually in existence, or the aether) that is appropriate for embedded work, but the constraints of the target make it difficult to envision.
Perhaps Fennel* fits the bill?

The Future of the Vim Project
I've also seen neovim plugins written in fennel [0], so if you want something lispy, that's possible now.

TimL: Clojure-like Lisp dialect that runs on and compiles down to Vimscript
Something similar: Fennel (https://fennel-lang.org/) is a lisp that compiles into Lua, which nvim can use as plugins, so you can write nvim plugins in a lisp. Aniseed (https://github.com/Olical/aniseed) makes this really easy.

Announcing automation-service: write and schedule home automation scripts in Lua
If you want a more FP language on the Lua runtime, you might be interested in Fennel. I wrote a post about adding Fennel compiler to a hslua interpreter a while back, which might be useful for you.
