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.

Compiling a Lisp
There's an effort afoot to bring this to the Clojure world, with the lovely name jank: https://jank-lang.org

A Tour of Lisps
I also liked that reference since I had not heard of Jank before. It is a work in progress so I just added a calendar entry for 9 months from now to check it out. https://jank-lang.org/

Boehm Garbage Collector
There will be a lot of room for this, once I build out more of the features. In particular, there will be a lot of Clojure libraries which need to gain jank support. Clojure doesn't require "porting", so to speak, since it has a special .cljc file which can use reader conditionals to check the host that it's in (clj, cljs, cljr, jank, etc). So anywhere those libs are using Java interop, we'd need to wrap it to use native interop instead.
On the compiler and tooling itself, I have some open issues here: https://github.com/jank-lang/jank/issues
The vast majority of it is heavy C++ work, though. Outside of that, the biggest gains will come from time spent on packaging, distribution, and testing on various platforms.
And if none of that sounds interesting or applicable, don't worry. Just be sure to join the Slack channel and hang out with us. :)

Using C++ as a scripting language, part 8
On the top of using C++ for scripting, and related to the discussion of CERN's ROOT/Cling, I am developing a Clojure dialect on C++/LLVM called jank: https://jank-lang.org/
jank is a true Clojure, meaning you get interactive, REPL-based development and a whole stdlib of persistent, immutable data structures and functions to transform them. But it's also C++, so you can write inline C++ within your jank source, and interpolate jank values within that. You can link with existing native code using LLVM and you can embed jank into your existing native projects to use for scripting.
jank is pre-alpha, right now, and I've only been showing it to Clojure devs so far, but there's a huge audience of C++ devs which may be interested in introducing Clojure to their native code.

[ANN] London Clojurians Talk: The jank programming language (by Jeaye Wilkerson)
jank (https://jank-lang.org/) is a Clojure dialect on LLVM with C++ interop. In this talk, Jeaye will cover jank's use cases, some challenges around building a native Clojure dialect, and some insights about Clojure itself found only by spelunking deep into the Clojure compiler.

Janet for Mortals
I wonder if Jank [1] could be such a Lisp? I haven't played around with it, but I really like the idea and would love to see it get more traction.

What's the value proposition of meta circular interpreters?
I've tried researching this myself and can't find too much. There's this project metaes which is an mci for JS, and there's the SCI module of the Clojure babashka project, but that's about it. I also saw Triska's video on mci but it was pretty theoretical.

Embedding cherry in an existing CLJS app for runtime eval
Since cherry is a compiler, the code generally runs faster than with SCI which is an interpreter. For many cases SCI is fast enough, but numerical computations in a hot loop isn't one of its strenghts:

Compiled and Interpreted Languages: Two Ways of Saying Tomato
Startup and sustained performance are absolutely implementation issues. For example, SBCL will take its sweet time to make machine code out of Common Lisp, but CLISP will interpret and generate bytecode. Both are useful, and both implement the same language. Clojure on the JVM takes also takes plenty of time to start up, so some use an interpreter instead. Furthermore neither of these languages has a cost model, so the cost of anything is an implementation issue.

Third party integrations with a monolithic Clojure app
So far we have relied on an increasing number of home-grown integration points to our platform, where relevant combined with the excellent SCI (so we can write some Clojure-code when adhoc data conversions / calculations / tweaking is required).

ClojureRS – Clojure interpreter implemented in Rust
Built with the lovely SCI library (https://github.com/babashka/sci) + GraalVM, probably the most useful GraalVM project I've seen in the wild so far.
Also, Babashka will probably always support more features than ClojureRS could ever, particularly the interop with the various Java classes/functions, as that'd be very hard to achieve in ClojureRS.
What are some alternatives?
