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.

Where's more discussion of the designs of effect systems?
Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.

Veryl: A Modern Hardware Description Language
of course it does! what else would you call something like chicken scheme [https://call-cc.org/], ats [https://ats-lang.sourceforge.net/], or ghc [https://www.haskell.org/ghc/]? they are not "scripts", they are full-blown compilers that happen to use C as their compilation target, and then leverage C compilers to generate code for a variety of architecures. it's a very sensible way to do things.

XL: An Extensible Programming Language
Agree about Haskell... as far as I'm aware there is actually no declarative/easily-readable definition of the Haskell syntax that is also complete, especially when it comes to the indentation rules, and the syntax is basically defined by the very (ironically) imperatively-defined GHC parser[0].
I prefer a syntax like in Pure[1], where the ambiguous, hard to parse indentation-based syntax is replaced by explicit semicolons (Yeah, you can use braces/semicolons in Haskell as well, but most code doesn't).

GHC 9.8.1 has been released
GHC is hosted on Gitlab, the Github repo is just a mirror. So money.

Introducing NeoHaskell: A beacon of joy in a greyed tech world
Depending on who you ask, a programming language can be different things. If you ask the Haskell community, many will tell you that the language is the Haskell specification, and that what currently is being used is not Haskell itself, but an extension of Haskell that is supported by the GHC compiler. Similar to the C language, a programming language would be a specification.
