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.

How to handle concurrency in Clojure with core.async
Hey, how you doing? This article was written right after I had to painstakingly read the clojure.core.async source code in order to finish a task. So, I hope I save you from the same fate as I had 😄.

Comparison of manifold and clojure.core.async
It was created by Rich Hickey: https://github.com/clojure/core.async/commit/47b1d24c0291050a1188dbeee2fc9227f694eb3c don't think he's disavowed it lol.

Sleeping is not the best option
Some time ago we developed some helpers using the capturing notifications strategy to test asynchronous ClojureScript code that was using core.async channels. Have a look at, for instance, the expect-async-message assertion helper in which we use core.async/alts! and core.async/timeout to implement this behaviour. The core.async/alts! function selects the first channel that responds. If that channel is the one the test code was observing we assert that the received message is what we expected. If the channel that responds first is the one generated by core.async/timeout we fail the test. We mentioned these async-test-tools in previous post: Testing Om components with cljs-react-test.

What is the difference between Manifold and core.async?
Hi there I'm using Clojure almost a year. I've played with both Manifold and core.async a bit but I'm not %100 sure when to use core.async over Manifold or vice versa.

Rich Hickey – open-source is Not About You
If you're not familiar with lisps in general, it might be hard to grok the differences between lisp-macros (as used in Clojure) and "normal" macros you see in other languages.
But, if you are familiar already, and just wanna see examples of neat macros that makes the API nicer than what a function could provide, here are a few:

> and with a very poor tooling (lack of IDE's)
Lisps have fantastic support in Emacs and VSCode and are in general simple enough languages that often the heavyweight of an IDE is not needed. But if you want IDEs there are:

Equivalent of select in core.async?
If you don't want to block the current thread, you can do the looking/waiting on another thread via thread or in a go using alts! .

Question regarding Recursive datatypes and cats typeclasses (Haskell to Scala)
Scala 2-only: * Shapeless (there is Shapeless for Scala 3 but less often needed as basic things are in Scala 3)
-
Is there the equivalent of this in Scala ? (Maps to Struct)
This is the FromMap typeclass in Shapeless. Note that there’s a companion syntax package for it providing .toRecord for any Map and an appropriately-structured Record (and a Record is the LabelledGeneric representation of a case class).

Scala 3: modifying product types in compile-time
If that's what you want, you can use Shapeless' records and HList. You can probably replicate this in plain Scala 3 with tuples and literal types as you said. It won't play nice with your others libs though but maybe there are integrations.

Does Scala have support for Dependent types?
See the Shapeless Sized example.

How does Scala's type system compare to TypeScript's? Is it as powerful?
Shapeless has Sized: https://github.com/milessabin/shapeless/blob/v2.3.9/core/src/main/scala/shapeless/sized.scala
-
Fp libraries that target scala 3 exclusively?
I know that libraries like Scodec and shapeless were rewritten practically from scratch for Scala 3, taking advantage of the next syntax and internals, as well as protoquill - a Scala 3 implementation of Quill.

That largely depends on the type system. Languages like Haskell and Scala which have much more powerful type systems than C/Java/Go/etc absolutely do allow you to do those sorts of things. It is a bit harder to wrap your head around to be sure and there are some rough edges, but once you get the hang of it you can get the benefits of static typing with the flexibility of dynamic typing. See https://github.com/milessabin/shapeless or a project that I've been working on a lot lately https://github.com/zio/zio-schema.

Scala3: Does it provide a simplified way of doing n-term generic parameters?
Just use cats and use the apply syntax .mapN for this. Seriously. There isn't a way to do it without generating source code that I can see in the api. Scala 3's HList Tuples aren't like Shapeless 2's HLists and I can't figure out a way in the api to reduce the tuple members down from (A, B, C, D) into an E, generically, yet with Scala 3 poly functions, unlike what you could do in Shapeless 2 with HList

Scala: A Love Story
Scala has sparked a huge ecosystem of very high quality libraries (Cats, Scalaz, shapeless, to name but a few). I think a major reason for this is that Scala attracts developers who value the advantages of the JVM, but are fed up with the limitations of the Java programming language and understand the benefits of an expressive type system and functional programming.
What are some alternatives?
promesa - A promise library & concurrency toolkit for Clojure and ClojureScript.
cats - Lightweight, modular, and extensible library for functional programming.
cloroutine - Coroutine support for clojure
magnolia - Easy, fast, transparent generic derivation of typeclass instances
zio-schema - Compositional, type-safe schema definitions, which enable auto-derivation of codecs and migrations.
Monocle - Optics library for Scala
lein-ancient - Check your Projects for outdated Dependencies
Scalaz - Principled Functional Programming in Scala
yesql - A Clojure library for using SQL.
Chimney - Scala library for boilerplate-free, type-safe data transformations
shadow-cljs - ClojureScript compilation made easy
scala-newtype - NewTypes for Scala with no runtime overhead
