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.

Learn Datalog Today
One of the easiest to get started on Datalog in my opinion is really clingo https://potassco.org/clingo/ , which can be pip installed and has python bindings. Answer Set Programming goes beyond datalog, but it holds datalog semantics as a sublanguage. It is unfortunate this is not well advertised.

Modern SAT solvers: fast, neat and underused (2018)
Love this article and the push to build awareness of what modern SAT solvers can do.
The thing it misses, though, is that there are higher level abstractions that are far more accessible than SAT. If I were teaching a course on this, I would start with either Answer Set Programming or Satisfiability Modulo Theories (SMT). The most widely used solvers for those are clingo [0] and Z3 [1]:
With ASP, you write in a much clearer Prolog-like syntax that does not require nearly as much encoding effort as your typical SAT problem. Z3 is similar -- you can code up problems in a simple Python API, or write them in the smtlib language.
Both of these make it easy to add various types of optimization, constraints, etc. to your problem, and they're much better as modeling languages than straight SAT. Underneath, they have solvers that leverage all the modern CDCL tricks.
We wrote up a paper [2] on how to formulate a modern dependency solver in ASP; it's helped tremendously for adding new types of features like options, variants, and complex compiler/arch dependencies to Spack [3]. You could not get good solutions to some of these problems without a capable and expressive solver.

Ask HN: What is new in Algorithms / Data Structures these days?
Answer Set Programming is an incredibly powerful tool to declaratively solve combinatorial problems. Clingo is one of the best open source implementations in my opinion: https://github.com/potassco/clingo

The Flix Programming Language
> recently added support for package management
Are there any [plans for] supply chain attack mitigations?
Naively searching, I find https://github.com/flix/flix/issues/4380#issuecomment-123641... (Proposed Principle: A package can be declared as "safe") and https://github.com/flix/flix/issues/2837 (Add capability-safety to polymorphic effects?) the latter closed with working on something related to this https://github.com/flix/flix/issues/3000 (The Road to Algebraic Effects).

Alternatives to scala FP
I don't know that it's one-to-one in terms of features, but I've been impressed with the Flix language, also on the jvm: https://flix.dev/ .

What the imperative shell of an Functional Core/Imperative Shell language looks like
I like it. Modern languages that distinguish between pure and impure programs like Flix, Koka, and Effekt do so on the type level instead of syntactically. This has three advantages:
-
[Q] Alternative languages; which one do you use?
I work almost 100% in Scala because it has the most advanced functional features (proper pattern matching, higher-kinded types, typeclasses, ...) and very powerful metaprogramming abilities, while being compatible with the Java OO model as long as you consume Java libraries (the other way around can be tricky, Kotlin is much better there). Only Flix takes it further but it's still an immature project.
