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.

Garbage Collection for Systems Programmers
The SGCL repository contains the source code for this benchmark that uses the tracked pointers: https://github.com/pebal/sgcl/blob/main/examples/treap/treap...

Boehm Garbage Collector
You can look at the SGCL garbage collector for C++: https://github.com/pebal/sgcl. It works in a separate thread, is locks-free and never stops the world.
-
The missing C++ smart pointer
It will never be called gc_ptr because C++ programmers have an allergy to the term GC. However, an attempt was made to implement a similar solution. Take a look at tracked_ptr: https://github.com/pebal/sgcl

Boehm-Demers-Weiser Garbage Collector
SGCL is a real-time garbage collector for C++ without any pauses.

Now the C++ removed garbage collector support, is it still possible the have a global garbage collector in a C++ application?
Removed GC support was useless. You can have GC pointers in C++.

The Year of C++ Successor Languages
Mutators are threads that allocate memory and manipulate pointers, they can work completely independently of the GC. A mutator needs only to tag an object when copies or moves a pointer to this object. The GC detects this tag and marks the object as alive. Here is a working implementation for C++: https://github.com/pebal/sgcl

Optimizing Concurrent Mark&Sweep latency? What are the ways?
I don't know Rust but you can have a pauseless GC in C++. You just need to provide asynchronous access to root pointers.

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.
