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.

Alternative Approach to Dynamic Environments: Using Octopod
In this post, I’d like to tell you how we use dynamic environments (review or preview environments) in our work here at Typeable, what issues we’ve managed to solve, and how and why we use our Octopod solution for these purposes instead of GitLab Dynamic Environments. In case you don’t know what the dynamic environment is, I recommend reading the post by Flant where the author gives a detailed account of the types of dynamic environments, their purpose and applications. The author also looks into this topic using GitLab as an example and provides detailed cases and descriptions. As for us, we use an alternative approach, somewhat different in terms of ideology, and work with review environments in Octopod. Previously we related the history of Octopod creation and the causes that motivated us to create it. We won’t repeat ourselves but will focus on the differences of our approach and the issues we’ve fixed.

Ask HN: It's 2022. Where should I direct the youths to learn about programming?
Loose connection, but made me remember https://code.world/ uses a Haskell-like functional language to define still pictures, animations, or even games.
- My kid loves computers. I would like him to start programming, just for fun to see if it is something for him. But how to start, what type of programming language that is appealing. Books? I mean, we can start with Lisp, but how long will attention hold? Please advise, thanks.

Game
I second gloss! It's a bit limited (no sound, fonts, nor even text centering, but you do have support for vector and bitmap graphics, color manipulation, mouse, keyboard, and animations), but it's so, so easy to use that I not only recommend it (or the similar Code World) for anybody's first game, I still use it for my newer games.

Functional Programming in OCaml
Two that I can think of:
- Bootstrap teaches a toned-down version of Racket (i.e. Scheme): https://bootstrapworld.org/materials/spring2021/en-us/course... . It's taught in some schools as well as a comp sci curriculum.
- https://code.world/ teaches using a toned-down version of Haskell. To my knowledge it's not used in schools.

Why I Support the Haskell Foundation
I had the silly 'fromString' error you get when using RebindableSyntax but had forgotten what to do next. Quick Google search and I hit on codeworld #59.

Hmmmmmmmmmmmmmmmmmmmmmm (SI is an AND gate, SAU is an OR gate)
That's a matter of tooling and environment. You can have a look at examples of drawing animations with physics simulation and user input at https://code.world. It's pure Haskell code without any scary abstractions, just functions from state to the next state.

Safe Haskell?
I'm not a user myself, but I understand Lambdabot and mueval depend on it. More generally, anything that executes Haskell code supplied by untrusted users would fit the bill. I don't know if CodeWorld for example allows user-supplied modules, but if it did they'd have to be Safe.

Do you recommend using ghc-pkg? Do you use it and why?
I also have a list of about 300 or so packages at https://github.com/google/codeworld/blob/master/codeworld-available-pkgs/codeworld-available-pkgs.cabal, which I'd like Cabal to solve and find compatible versions to make available, preferably without listing them all on one massive command line! There are limits on the length of a command line. I don't know if cabal install --lib will expose packages that are dependencies, but not actually listed on the command line, in the resulting environment.
You know, now that you mention it, that sounds familiar. There's an issue for this at https://github.com/google/codeworld/issues/1182, and having cabal set up an environment file for GHC is mentioned there. There are some other complications: for example, with cabal v2-install, I can't seem to list multiple packages in local directories. So the answer to that seems to be creating a cabal.project file that lists them all... but then I want to install all of the packages from that cabal.project file into the environment, and their dependencies, and also make the consistent set of dependency versions that work with them (as chosen by Cabal's constraint solver) available in an environment for any further projects built against those same libraries.
What are some alternatives?
Cabal - Official upstream development repository for Cabal and cabal-install
dune - A composable build system for OCaml.
reanimate - Haskell library for building declarative animations based on SVG graphics
kubernetes-webhook-haskell - Create Kubernetes Admission Webhooks in Haskell
retro-httpaf-bench - Benchmarking environment for http servers
hercules-ci-agent - https://hercules-ci.com build and deployment agent
PulseSensorPlayground - A PulseSensor library (for Arduino) that collects our most popular projects in one place.
