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.

NixOS + Haskell best practices circa March 2023
A while ago I've put together a little skeleton that i use when creating new haskell projects: https://github.com/pwm/nixkell

Most braindead easy end to end haskell workflow?
Quite the opposite of caveman. You are used to 21st century tooling that not long ago Haskell simply did not have. I can relate. Luckily nowadays we have HLS thanks to all the amazing people involved. With HLS the IDE/editor matters less as long as they can use it. You probably would be most at home with VSCode. Re setup here’s a shameless nix-based plug: https://github.com/pwm/nixkell (Watch the gif in the readme)

Can't get things to work. It is normal to learn haskell with plain vim?
I've actually just started a small side-project trying to replicate the UX of stack with nix: https://github.com/pwm/nixkell

The Haskell job market has been growing steaily since 2008
We used reflex-frp, so our app was a webview that worked on localhost and Android. The docs say it also works on iOS but we don't have an iPhone.
The process was learning Functional Reactive Programming, then learning reflex-frp, then getting a contract with obsidian (creators of reflex) for one hour a week where we could ask questions.

We had a grant requirement to create a phone client for Tahoe-LAFS, a Python application with a bunch of dependencies, including ZFEC, a forward error correction library.
( https://tahoe-lafs.readthedocs.io/ )
( https://github.com/tahoe-lafs/zfec/ )
We needed bug for bug compatibility with the Python codebase, so I ran Tahoe on localhost and tested the Haskell client against the Python server. We used servant to build the API, since it builds both client and server side from the same description.

Exploring ideas in Haskell
The type classes do take a toll on performance, but in reflex-platform we change GHC's default flags to make the situation a lot better. It's still not ideal, but our performance winds up being OK for real applications. The most important part is that the performance scales reasonably well as the application grows. It might probably be good at some point to use backpack instead of a typeclass so that specialization can be enforced - though I'd prefer if GHC gave a way to just force specialization more effectively.

Any News On Haskell For Android ?
Obelisk / reflex-platform contain nix-based solutions to building Haskell code for mobile, so you might be interested in checking out how they do it (or just using them).

Creating a Haskell Application Using Reflex. Part 1
In this series of posts, we will describe how a Haskell web application can be developed using reflex-platform. reflex-platform offers reflex and reflex-dom packages. reflex package is the Haskell implementation of Functional reactive programming (FRP). reflex-dom library contains a large number of functions, classes, and types used when dealing with DOM. The packages are separated as it is possible to use the FRP approach not only for web-development. We will develop theTodo List application that allows carrying out various manipulations on the task list.

Setting up Reflex with VS Code in WSL
To clarify the situation, the canonical way to develop reflex-dom projects is to start from the reflex-platform. See here: https://github.com/reflex-frp/reflex-platform/blob/develop/docs/project-development.rst

Nix - WSL - no C compiler provided for this platform
This might also be coming from the tests of the library (even if they can run in the browser, their tests might not). You can disabled tests using an overrides attribute in project.nix (if using reflex-stone). You can see what it should look like here : https://github.com/reflex-frp/reflex-platform/blob/develop/project/default.nix#L79. You should add this attribute at the same level where "useWarp = true;" is. This should then have lines like "diagrams = pkgs.haskell.lib.dontCheck super.diagrams;" for example if you want to disable the tests for the diagrams package.

Can I embed Reflex-FRP in a larger site?
then you compile to js using ghcjs like this, then closure compile and gzip it to get the size way down. Then it just becomes a normal script you include wherever you need it.
