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.

Experimenting with the new Typed Racket modes

Coalton: How to Have Our (Typed) Cake and (Safely) Eat It Too, in Common Lisp
Last weekend, I put together a working sample for how to show multiple syntax errors from Racket macros. It works in DrRacket and racket-xp-mode. It's based on Typed Racket.
https://gist.github.com/srcreigh/f341b2adaa0fe37c241fdf15f37...
The well-documented Racket `raise-syntax-error` will let you display 1 syntax error at a time. It works by throwing an exception during macro expansion hence you only get 1 error in your IDE. That code lets you highlight 2+ errors.
Please build a type system in Racket! I would love to try it out.
Helpfully, the above sample code is an example of how to store compiler-level state. So next, just wrap all your base forms, add some type declaration syntax, type inference, etc.
I would love to have a language that can be used to define a customized type system in Racket.
Typed Racket is an incredible feat. Can you imagine adding an entire type system without writing a separate compiler? Using all the batteries included with your language?
However I don't like that Typed Racket enforces soundness with Runtime checks, I much prefer TypeScript style checking. I also have run into some pretty confusing messages ie [1]. Diversity is healthy, it'd be nice to have static typechecking systems to choose from for Racket.

Creating Languages in Racket (2011)
> I like how TS is unsound (has no runtime performance penalty for mixing untyped code), and is easily disabled via any if it's in the way.
This is already done. See https://github.com/racket/typed-racket/pull/952 for RFC and https://github.com/racket/typed-racket/pull/948 for the implementation.
