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.

Revisiting Haskell after 10 years
Writing Haskell programs that rely on third-party packages is still an issue when it’s a not actively maintained package. They get out of date with the base library (Haskell’s standard library), and you might see yourself in a situation where you need to downgrade to an older version. This is not exclusive to Haskell, but it happens more often than I’d like to assume. However, if you only rely on known well-maintained libraries/frameworks such as Aeson, Squeleto, Yesod, and Parsec, to name a few, it’s unlikely you will face troubles at all, you just need to be more mindful of what you add as a dependency. There’s stackage.org now, a repository that works with Stack, providing a set of packages that are proven to work well together and help us to have reproducible builds in a more manageable way—not the solution for all the cases but it’s good to have it as an option.

Leaving Haskell Behind
> That is fine, as far as it goes, but obviously this will, at some point, be at odds with the interests of programmers looking to use Haskell as a practical, stable tool.
That's what Stackage is.
Stackage provides consistent sets of Haskell packages, known to build together and pass their tests before becoming Stackage Nightly snapshots and LTS (Long Term Support) releases. [1]
Java will never get this.

Monthly Hask Anything (March 2022)
I don't see way community maintenance can change the GHC for nightly.

Is it possible to install C libraries before building on Hackage?
It makes total sense that it fails since at no point I requested that the library be installed, which makes me wonder: Is there any way to request Hackage to install SDL and GLEW before attempting the build? I see Stackage has debian-bootstrap.sh. Does something similar exist for Hackage?

No idea how to add packages
At this point, you can try a Stack snapshot that uses an older version of GHC. Looking at Stackage, you can see that the latest version before 8.10.* is 8.8.4 (using LTS 16.31). Starting over with that snapshot, you find that the packages that you need are in the snapshot and work.

[GHC Proposals] GHC Maintainer preview
On the contrary, I think this is standard practice for packages which are part of stackage. When stackage nightly switches to a new version of ghc, all the packages which are incompatible with the new ghc are dropped from nightly. My understanding is that maintainers are then expected to fix their packages, at which point more and more packages are included in the nightly snapshot. The next lts to include that version of ghc is only released later, once most packages have been added back, so unlike ghc users who diligently upgrade to the latest ghc, stackage users who diligently upgrade the latest lts snapshot shouldn't see a big drop in the number of compatible packages.

Should I use newer ghc?
Someone has opened a PR for accelerate here https://github.com/AccelerateHS/accelerate/pull/525 (sadly seems not actively maintained at the moment, but that can always change if people care enough). I agree for an executable you should freeze your dependencies and compiler version, and using 8.10 is fine. Although there are tons of improvements in 9.2+

Haskell deep learning tutorials [Blog]
Backprop is a neat library. However, I guess its use case is if you actually don't want to go for anything standard like Torch or TF (perhaps for research?) For instance, if I were to use something like Accelerate for GPU acceleration, or some other computation-oriented library, then I would mix it with Backprop. Previously, I have benefited from Backprop in a ConvNet tutorial and I liked it.

I made a petition to get the accelerate project for Haskell some funding.
Wait, really? Here's a conversation I had with him: https://github.com/AccelerateHS/accelerate/discussions/528

Who is researching array languages these days?
I know Accelerate is being developed at Utrecht University in the Netherlands. You can look at publications by Trevor McDonell to get a taste of what they are doing.

Introduction to Doctests in Haskell
Looking for a few projects that make use of it, I found accelerate, hawk, polysemy and pretty-simple, so I'll be interested to poke around in their code and see how they have things set up.

There's accelerate for GPU computing and hmatrix for bindings to BLAS and LAPACK.

Idris2+WebGL, part #12: Linear algebra with linear types... not great
I'm toying with the idea of replacing vector values with vector generators, where e.g. v1 + v2 is not evaluated to a new vector, but to a vector program. This is similar to the approaches of Accelerate and TensorFlow. On the flip side, I don't think I could get rid of the overhead, and I expect much smaller computation loads than aforementioned libraries, so overheads could be very significant. The added benefit of using vector generators is that the generator could not only be evaluated, but also be turned into a Latex formula.
