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's in a (C) box?
Once I got to know it, I had to implement a small header library C (available on Github). It allows writing code like this:

What the imperative shell of an Functional Core/Imperative Shell language looks like
I like it. Modern languages that distinguish between pure and impure programs like Flix, Koka, and Effekt do so on the type level instead of syntactically. This has three advantages:
-
Algebraic Effects: Another mistake carried through to perfection?
The problem with checked exceptions been identified and solved. The same problem and solution applies to effect handlers. Effekt is a language with lexical effect handlers which doesn't have this problem. Consider the following program in Effekt:
-
Is continuation passing style conversion still used as an intermediate language?
Yes, for you this is the right decision. But for us going to CPS makes everything significantly easier and in cases where you do use control effects significantly faster. For our language Effekt we are exploring different tradeoffs in different backends.
-
The Registers of Rust - Without boats, dreams dry up
This pattern they observe is nicely captured by effect handlers. These examples are written in Effekt.
-
An approach to manual memory management and side effect handling system, feedback, ideas and thoughts requested
This is beyond my level of expertise. But effect tracking? There are some cool languages out there that do that consistently! Search for "algebraic effects". My favorite is Koka. Effekt also seems to be a popular choice.

Is there a garbage collected, statically typed language, that has null safety, and doesn't use exceptions?
Examples are languages like Koka, Effekt, Links, or Unison. These languages come with a type-and-effect system: a function's type not only tell you which values the function accepts and which values it returns, but also which effects it has. This is relevant to your question, because throwing an exception is one such effect.

The Val Object Model: Template for a possible future Swift object model
It seems that with Effekt we are pursuing the same goal, but coming from the opposite direction, perhaps one day we will meet in the middle :). We start from a purely functional language and carefully add effects like mutation.
