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.

Can GHCi be run like PDB?
Another thing you can try is the ghc-wpc project which has an interpreter which supports breakpoints, though you may need to hack little a bit to achieve your goals.

Haskell compiled onto LLVM increase performance?
Here the goal is to build a high level, easy to understand model for all GHC backend features. Validations is also required. Once we know the semantics of GHC primops and RTS features then it becomes possible to figure out how to compile Haskell programs to GRIN. I started the GHC-WPC project for this reason. GHC-WPC exports the STG intermediate representation for the whole Haskell program, and I wrote an STG interpreter from scratch in Haskell that can run any Haskell program. (i.e. GHC itself) The STG interpreter is the high level model for the GHC primop and RTS semantics. It implements all these in pure Haskell, it does not depend on GHC RTS at all.

Why is the debugger so bad in Haskell? (or is it just me)
I can easily debug any Haskell program with the external STG interpreter. https://www.youtube.com/watch?v=DkDUEd3pUyM https://github.com/grin-compiler/ghc-whole-program-compiler-project

What are you hyped about today?
I haven't gotten my hands dirty yet, but really excited hearing GHC-WPC is going on!
-
GHC Pluggable Backend?
Why didn't you mention GHC-WPC? It is also a backend sample. It exports enough information (STG + linker opts + c bits) to interpret the program or to generate a binary executable via the regular GHC codegen system. https://github.com/grin-compiler/ghc-whole-program-compiler-project

Transpiling to GHC Core language
You could use the GHC codegen and RTS via the external STG IR. https://github.com/grin-compiler/ghc-whole-program-compiler-project

Next-gen Haskell Compilation Techniques
Remarks: 1. Strict functional languages can be expressed in STG without overhead, because STG has explicit liftedness control. In a strict language every data is unlifted or unboxed. 2. Supporting all GHC primops is not unrealistic. See the primop implementation in the external STG interpreter source code. Here is the implementation of the threading primops.

I am looking for a new maintainer for Mueval
Mueval is based on hint, which is in turn based on the ghc library.

Interactive animations
Yeah, that project is pretty much at the bottom of my list, unfortunately. My top projects these days are mgmt, klister, recursion-schemes, and hint... And that's already too much!
-
Can GHCi be run like PDB?
You can try using hint (instead of ghci) though I'm not sure it has the breakpoint functionality.

Dynamic loading of modules
Have you tried hint?

hint: Runtime Haskell interpreter
with haskell.nix, well, you've found the github issue, you need to put the apecs package in the right nix incantation.

Seeking a Project Lead for Matchmaker - Haskell Foundation
Yes please! Right now all of my open-source projects (most notably hint and recursion-schemes) are about to drop into barely-updated mode, and while I knew this would happen and have been working towards finding co-maintainers, I am now realizing that it wasn't enough. I think such a website would definitely have helped, and I am hoping that once it launches, I'll be able to use it to find some co-maintainers to tide over my projects until I become available again.

Deep embedding of Haskell in Haskell
hint's API takes a string, not an AST (I plan to fix this). Internally, hint delegates to the ghc library, which does expose a parser which you can use if you want. hint exists to provide a friendlier API than the ghc library for interpreting Haskell code, but it does not expose a friendlier API for parsing Haskell code.
