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.

What features would you want in a new programming language?
It also offers a great Inversion of Control mechanism where everything is customisable, and, unlike Capability Objects, AESs also offer compatibility with type inference (you can pass functions doing IO to map, and it Just Works(TM)) and first-class control over stack frames (because really a continuation function is just some stack frames, which you can manually move to the heap if you want a closure; which means async is an effect!). It also is composable in ways Monads are not.

What are you doing about async programming models? Best? Worst? Strengths? Weaknesses?
Koka and other languages implementing Algebraic Effect Systems make everything a user-defined case of coroutines: async is just another effect/Monadic type. Zig does something similar by having first class stack frames, making all function calls possibly asynchronous.

Letlang, a programming language targetting Rust - Road to v0.1
Super interesting, there is a proposal to add this to JavaScript and several languages that use this, unison, koka & eff. I had no idea this was even a thing!

Let's collect relatively new research programming languages in this thread
https://github.com/koka-lang/koka Algebraic effects and reference counting. https://github.com/mit-plv/koika hardware description DSL for coq
Koka, already cited in this thread, early 2010s. Koka's first claim to fame was a usable effect system (at the type were, basically, effect systems were not usable in practice; in fact few languages have managed to do as well as Koka since). Now its author is working on cool implementation strategies for functional languages as well.

[Offer] Tutoring for Computer Science / Programming / Software Engineering topics
I'm a software engineer with 3 years of professional experience. I worked for 2 years at Microsoft on Azure Compute and now work at Google, working on improving Google search. I am the sole maintainer of the popular open-source library microlens with 80k downloads. I've also contributed to the Koka programming language developed at Microsoft Research.

Implementing the Perceus reference counting GC
By implementing all of those optimizations in the Koka programming language, they achieved GC overhead much less and execution time faster than the other languages including OCaml, Haskell, and even C++ in several algorithms and data structures that frequently keep common sub-structures of them, such as red-black trees. For more information, see the latest version of the paper.

Structurally-Typed Condition Handling
Yes -- I think historically the power of condition handling was not well understood and algebraic effect handlers were a "rediscovery" coming from well-studied category theory (Plotkin, Power, and Pretnar).
If you want to play with "structurally typed condition handling", then the Koka language has "row-typed algebraic effect handlers" that compile to C: <http://koka-lang.org>

wasm-effect-handlers - WebAssembly specification, reference interpreter, and test suite with effect handlers extension.
FStar - A Proof-oriented Programming Language
dafny - Dafny is a verification-aware programming language
zig - General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
pen - The parallel, concurrent, and functional programming language for scalable software development
Rust-for-Linux - Adding support for the Rust language to the Linux kernel.
ocaml - The core OCaml system: compilers, runtime system, base libraries
checkedc - Checked C is an extension to C that lets programmers write C code that is guaranteed by the compiler to be type-safe. The goal is to let people easily make their existing C code type-safe and eliminate entire classes of errors. Checked C does not address use-after-free errors. This repo has a wiki for Checked C, sample code, the specification, and test code.
