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.

Haskellers who moved to Rust: What has been your experience?
You can swap-out implementations for testing, avoid the crazy N^2 instances issues, etc. They're pretty cool. Currently there are many competing libraries. polysemy and eff both have good examples on their homepages.
-
What are the current hot topics in type theory and static analysis?
Effect systems and Algebraic effects. ocaml has just released a stripped-down effect system. People are also working on Effect systems for Haskell (eff, fused-effects, effet). Koka is a language built with effects first and foremost and it’s rapidly gaining popularity. Unison also has effects.

[ANNOUNCE] GHC 9.6.1 is now available
There are also a few subtle issues that arise with delconts related to semantics of higher order effects (see here and here), but they might be solvable.

Effectful | Paweł Szulc | Lambda Days 2022
Details are in https://github.com/hasura/eff/issues/12 and https://www.reddit.com/r/haskell/comments/pywuqg/unresolved_challenges_of_scoped_effects_and_what/.

Looking for languages that combine algebraic effects with parallel execution
You'll get fearless parallel with STM in the mixture, and GHC is getting a work in progress effect system for Haskell, as Delimited continuation primops has been merged.
-
Should I pick up OCaml or Haskell?
My last example is algebraic effects, some of which have been made possible in a both practical and efficient way thanks to extremely recent research, and that I can use to implement architectures like Ports and Adapters or Clean Architecture and have very maintainable code. (Extensible Effects — An Alternative to Monad Transformers was published in 2013, Effect Handlers in Scope was published in 2014 and they are behind Polysemy, while there is ongoing work on effects with even better performance, like Eff)

[ANN] cleff - fast and consise extensible effects
cleff's Eff monad is esentially implemented as a ReaderT IO. [...] This is first done by eff, [...]

Opinions on Reader + Continuation-based IO?
Here is link number 1 - Previous text "eff"
This is essentially how continuation based effect systems work, check out eveff and eff.
-
Where's more discussion of the designs of effect systems?
Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.

Ask HN: Why are all of the best back end web frameworks dynamically typed?
I found IHP straightforward:
https://ihp.digitallyinduced.com/
despite not remembering much haskell!
This assumes you can get past nix for the install.
I find IHP well-designed. I just wish the licensing scheme were more transparent.
IHP is a batteries-included web framework similar to "ruby on rails" for Haskell, with strong static typing.
The website has lots of information and videos and beginner tutorials.

Haskell Optimization Handbook
In case this got you interested in Haskell, and you want a good way to start your Haskell journey (and have something to apply the optimization handbook to), check out IHP. It's the Rails/Laravel of the Haskell world. You can start here https://ihp.digitallyinduced.com/Guide/index.html or check it out on GitHub here https://github.com/digitallyinduced/ihp

Show HN: Algora.io – Open-source development bounties
At IHP we've been using Algora for a while now and it works really great. Here's e.g. one PR that was merged last week with a bounty attached https://github.com/digitallyinduced/ihp/issues/1621 Everything was set up in less than 15 minutes and ioannis and zafer have been super helpful with any questions we had.
In general I think this is a good direction and an interesting take on the open question around sustainable open source. Congrats on the launch and keep up the great work! :)

Any open source projects to contribute to for beginners
You could contribute to IHP! We have some great docs to get started here https://github.com/digitallyinduced/ihp/blob/master/CONTRIBUTING.md And we have some low hanging fruits in GitHub issues for you to get started with, e.g. https://github.com/digitallyinduced/ihp/issues/1601 (also there's always lots of activity in the IHP Slack, in case you have any questions/need help)

Show HN: IHP v1.0 (Batteries-included web framework built on Haskell and Nix)
Really happy we've finally go to the 1.0 status :) If you like to take a look at the code, check our GitHub at https://github.com/digitallyinduced/ihp

Is there an Elm like framework for cross-platform apps?
kinda early for running roc in production perhaps, but you can try out haskell and its frameworks like ihp or some other web / mobile / multiplatform framework.

Why Haskell Is Interesting?
In recent years the Haskell ecosystem has drastically improved.
With Haskell Language Server (HLS) there's now great autocompletion and inline error reporting for e.g. VSCode and other editors.
We've recently got dot-notation, so you can type `myRecord.myField` instead of `myField myRecord`, which makes Haskell code feel more familiar when switching from other languages.
With IHP we now even have a Haskell version of Rails/Laravel. Check it out here: https://ihp.digitallyinduced.com/ (I'm founder of IHP)
