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.

Permutation Iteration and Random Access
Here is Lisp code [1] that maps all sorts of combinatorial objects—permutations, bit sets, base-B integers, multi-set permutations, etc.—perfectly into the smallest set of integers [0, n-1] and back. (In a sense, it's a perfect hash.) This is used to efficiently solve combinatorial puzzles.

Can a Rubik's Cube be brute-forced?
Note that in the unlikely event anyone wants to run the code in the post, the algorithm presented is still in an open PR, APIs change until merged, etc.
- Favorite Lisp project? Shameless plugs welcome & encouraged!

Is Fisher-Yates Shuffle (aka Knuth Shuffle) implemented in some vetted CL library?
CL-PERMUTATION has random-perm to produce a random permutation of even, odd, or any parity.

We need to talk about parentheses
Examples (for Common Lisp, so not citing Emacs): reddit v1, Google's ITA Software that powers airfare search engines (Kayak, Orbitz…), Postgres' pgloader (http://pgloader.io/), which was re-written from Python to Common Lisp, Opus Modus for music composition, the Maxima CAS, PTC 3D designer CAD software (used by big brands worldwide), Grammarly, Mirai, the 3D editor that designed Gollum's face, the ScoreCloud app that lets you whistle or play an instrument and get the music score,
but also the ACL2 theorem prover, used in the industry since the 90s, NASA's PVS provers and SPIKE scheduler used for Hubble and JWT, many companies in Quantum Computing, companies like SISCOG, who plans the transportation systems of european metropolis' underground since the 80s, Ravenpack who's into big-data analysis for financial services (they might be hiring), Keepit (https://www.keepit.com/), Pocket Change (Japan, https://www.pocket-change.jp/en/), the new Feetr in trading (https://feetr.io/, you can search HN), Airbus, Alstom, Planisware (https://planisware.com),
or also the open-source screenshotbot (https://screenshotbot.io), the Kandria game (https://kandria.com/),
and the companies in https://github.com/azzamsa/awesome-lisp-companies and on LispWorks and Allegro's Success Stories.

Factorio: Space Age
> The source is not publicly available, no. It‘s still being actively developed and sold after all.
Those two are definitely not incompatible. Take Karia[0] for example, which is fully Free Software[1].

The battlebit discord anticheat “helpers” everybody.
I’ve seen a 1 person team support steam deck controls with a game written in lisp kandria. The battlebit devs have much better tools supporting steam deck using the unity engine. The controls for the steam deck is definitely not the main reason to abandon Linux, the anti cheat stuff seams to be the only thing in the way.

best lisp or scheme for web game dev?
I don't know about "best", but the work that the Kandria dev has put into CL libraries to create his game has been impressive to see.
- Owner of Symbolics Lisp machines IP is interested in a non-commercial release
- Steel Bank Common Lisp 2.3.5 released
- Peter Norvig – Paradigms of AI Programming Case Studies in Common Lisp

Looking for multi-paradigm languages that have reliable tail-call optimization
For what it's worth, I'd take a look at Common Lisp. It's perhaps less functionally-minded than OCaml, but I don't think it's fair to call it imperative. You'll encounter similar-looking patterns. There aren't loads of games for CL, but I've heard Kandria is super (https://github.com/Shirakumo/kandria), as well as being a great example project.
