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.

Ask HN: Best stack to make a 2D game in 2023
I've personally had a very good experience with Haxe and Haxeflixel (https://haxeflixel.com/) although Heaps (https://heaps.io/) seems to be more popular nowadays.
Haxe is very nice as a language, can easily cross-compile to a lot of targets, Haxeflixel is heavily inspired by some Actionscript framework and has a lot of goodies. Maybe Heaps is more mature, up to date and allows for more advanced features.

What is the worst engine you've ever used and why?
Not really the worst, but you can say my least favorite, and that would be heaps.io
-
why are gamedevs so against sharing code?
Yeah I think it's ideal for 2D development. Look into heaps.io . . you might like it! These days it seems the best source of community for haxe is in their official discord server.

Picking a language
Many frameworks will let you export for the web, even if you don't code your game in JS. Unity, Godot, Bevy(?), heaps.io ... the list goes on and on.

I tried the Flash AS3 at school and it was nice
It takes a little while to get comfortable with heaps.io, largely because tutorials in the Haxe world are pretty limited. Here's a good place to start:
-
Everybody always says to 'build your own projects' or 'solve your own problems', what are some things you've done or personally solved for yourself that can inspire others to get their own ideas from?
I'm going to go out on a limb and say that most people use Unity or Godot for jams these days. But as long as your framework exports for the web, you should be fine. Personally, I use haxe and heaps.io, but it's a bit of an outlier and probably requires learning a new language on top of learning a framework.

Types versus sets (and what about categories?)
This was recently deemed inappropriate:
"Bye bye Set"
"Set and Prop are removed as keywords"

If given a list of properties/definitions and relationship between them, could a machine come up with (mostly senseless, but) true implications?
Still, there are many useful tools based on these ideas, used by programmers and mathematicians alike. What you describe sounds rather like Datalog (e.g. Soufflé Datalog), where you supply some rules and an initial fact, and the system repeatedly expands out the set of facts until nothing new can be derived. (This has to be finite, if you want to get anywhere.) In Prolog (e.g. SWI Prolog) you also supply a set of rules and facts, but instead of a fact as your starting point, you give a query containing some unknown variables, and the system tries to find an assignment of the variables that proves the query. And finally there is a rich array of theorem provers and proof assistants such as Agda, Coq, Lean, and Twelf, which can all be used to help check your reasoning or explore new ideas.

What can Category Theory do?
Haskell and Agda are probably the most obvious examples. Ocaml too, but it is much older, so its type system is not as categorical. There is also Idris, which is not as well-known but is very cool.
-
What are the current hot topics in type theory and static analysis?
Most of the proof assistants out there: Lean, Coq, Dafny, Isabelle, F*, Idris 2, and Agda. And the main concepts are dependent types, Homotopy Type Theory AKA HoTT, and Category Theory. Warning: HoTT and Category Theory are really dense, you're going to really need to research them.

Amendmend proposal: Changed syntax for Or patterns
Does this come with plans to separately unify the body with each of the contexts induced by matching on each of the respective patterns (similar to what’s discussed here), or will it behave like the _ pattern and use only the most general context?

Functional Programming and Maths <|> How can a code monkey learn Agda?
That's absolutely untrue. From the horse's mouth:

FP language idea - would this is possible to infer and type check?
Agda has the so-called mixfix operators (which are powerful enough to cover pre/in/postfix cases with an arbitrary number of arguments), check that out: - https://agda.readthedocs.io/en/v2.6.1/language/mixfix-operators.html - https://github.com/agda/agda/blob/master/examples/Introduction/Operators.agda - https://github.com/agda/agda-stdlib/blob/master/src/Data/Product/Base.agda

Best Programming Language for Computational Proof
Coq, Agda, Lean, Isabelle, and probably some others which are not coming to my mind at the moment, but those would be considered the major ones.

Do you use Idris or Coq, and why?
Funny that you say this, because there are some obvious long standing open feature requests with looking up the type of the term under cursor — № 4295 and № 516. I am not blaming anyone in particular — this is the way it is. I wish I could find time to rewrite the proof search engine (how hard can it be), but I am already buried under a pile of other commitments and a good chunk of overwhelming sadness.
