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.

Vala Programming Language
Ahh takes me back!
In 2009 I wrote a lib to auto-generate Ruby bindings for Vala code. It gave a very pleasant API to create native extensions for Ruby, if you were happy using glib.

Or Val[0], now called Hylo (for a good reason), or V[1].

Cpp2 and cppfront – An experimental 'C++ syntax 2' and its first compiler
The evolution of C++ has been a multi-decade history of dealing with difficult reality.
I have great hope that Herb can create with his cppfront project “The Very Best of C++” to carry that tremendous legacy forward.
If I was to throw my hat into a “C++ successor”, it would be https://www.hylo-lang.org/ with its “all the safeties” and “tell you when you’re doing it sub-optimal” approach.

Borrow Checking Hylo [video]
Paper: https://2023.splashcon.org/details/iwaco-2023-papers/5/Borro...
> Hylo is a language for high-level systems programming that promises safety without loss of efficiency. It is based on mutable value semantics, a discipline that emphasizes the independence of values to support local reasoning. The result—in contrast with approaches based on sophisticated aliasing restrictions—is an efficient, expressive language with a simple type system and no need for lifetime annotations.
> Safety guarantees in Hylo programs are verified by an abstract interpreter processing an intermediate representation, Hylo IR, that models lifetime properties with ghost instructions. Further, lifetime constraints are used to eliminate unnecessary memory allocations predictably.

Why do lifetimes need to be leaky?
A model without lifetimes is also being explored in other languages, e.g. in Hylo. It sacrifices expressiveness, but on the other hand you don't have to deal with explicit lifetimes!

D Programming Language
Why go through all the trouble when you can do this: https://www.hylo-lang.org/ and not spend a second thinking of lifetimes? No, copies will not be issued unless necessary.
Or why not keep exploring this idea as well? More research-oriented than the first one right now, though, so take it with a grain of salt: https://vale.dev/

I've heard that "Rust's borrow checker is necessary to ensure memory safety without a GC" usually also implying it's the only way, but I've done the same without the borrow checker. Am I just clueless/confused?
Get rid of references at the cost of some expressivity (see Hylo, formerly Val)
