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.

Why Do ML on the Erlang VM?
I thought this was a call for Standard ML or something a rather on the Erlang VM.
(I really enjoyed this article though!)
As far as I know theres a few implementations of ML like languages on the Erlang VM

caramel and alpaca are worth checking out.
Gleam doesn't look like a ML lang but has a lot of the same semantics of a ML lang

Lunatic is an Erlang-inspired runtime for WebAssembly
Elixir, LFE, etc. seem to work fine for the people who enjoy them.

LFE is Virding's himself, and has been around for longer than Erlang has been popular: Robert Virding - LFE - a lisp flavour on the Erlang VM (Lambda Days 2016) https://www.youtube.com/watch?v=Br2KY12LB2w

A mini-Erlang/Elixir -- tell me if/why my idea sucks
The Beam Languages repo is filled with projects to build on top of Erlang and the BEAM to take inspiration from.

Switching to Elixir
I don't think the implementation itself is at fault, but yes, I do think that the design of dialyzer makes it an (at times) faulty type checker. The unfortunate reality of a type checker that fails sometimes is that it makes it mostly useless because you can never trust that it'll do the job.
To be clear, I've had it fail in a function where I've literally specced that very function to return a `binary` but I'm returning an `integer` in one of the cases. This is a very shallow context but it can still fail. Now add more functions, maybe one more `case`.
I think an entire rethink of type checking on the BEAM had to be done and that's why eqWalizer[0] was created and why Elixir is looking to add an actual sound, well-developed type checker. Gleam[1] I would assume is just a Hindley-Milner system so that's completely solid. `purerl`[2] is just PureScript for the BEAM so that's also Hindley-Milner, meaning it's solid. `purerl` has some performance issues caused by it compiling down to closures everywhere but if you can pay that cost it's actually pretty fantastic. With that said my bet for the best statically typed experience right now on the BEAM would be `gleam`.

Phoenix 1.7 is View-less
While it's not static-typing, compile-time type checking for Erlang have come a long way: Eqwalizer works pretty well - but I may be biased since my employer sponsors the project.

[New] How do you verify program correctness in Elixir?
Note there is also research happening in this area by the Elixir team. The WhatsApp is also working on static types for Erlang, which I am certain will be available for Elixir too at some point.

Elixir Livebook now as a desktop app
From the discord blog posts it seems that elixir powers the chat system, with rust and python as the other two main languages in their stack.
As for whatsapp, they are mainly a erlang shop and yesterday they open sourced a type checker for erlang:
