22nd edition of Haskell Communities and Activities Report is out

22nd edition of Haskell Communities and Activities Report has just been released. Here’s an overview of new informations:

  • Learn You a Haskell was translated into Japanese. Japan is lucky, they already have edition of Real World Haskell.
  • Edward Z. Yang is now the editor of The Monad Reader.
  • There is a lot of progress on GHC development. Some features will be present in 7.6 release, some are work in progress with no release date yet. Among them are:
    • adding support for holes: you could write incomplete code with some fragments missing (these are holes) and GHC would report the type that hole can have. This is inspired by Agda.
    • There is work on new code generator, though I’m not sure how this relates to the LLVM backend.
    • There is possibility to change number of utilized cores at runtime. Previously it was possible only when starting the program and it couldn’t be changed once the application started.
    • SIMD instructions support for LLVM backend is on the way, hopefully will make it into 7.6.1. Since I’m doing mostly numerical computations I’m looking forward to it.
  • There’s a lot of progress on Haskell web frameworks: Yesod (stable version was released about a month ago) and Snap (two major releases since the last report).
  • Portackage is a new portal that gathers informations form Hackage. It definitely needs more development work, but I think it has potential to become useful.
  • And last, but not least: Yet Another Haskell Blog is also mentioned in the report.

I’ve found some other interesting things in the report, mostly informations about projects that concentrate on parallel computations in Haskell: Data Parallel Haskell, Glasgow Parallel Haskell and Parallel GHC Project. I’m especially interested in these – though I don’t have any knowledge in that area yet – because it looks that parallelization of computations can be done a whole lot easier within the functional programming paradigm. There are many new Haskell projects mentioned in the report as well, but they are beyond the scope of my interests so I didn’t mention them. Read the full report here – you’ll most likely find other interesting stuff.
