• Moving Stackage Nightly to GHC 8.0

  I’ve been really impressed with how many of my projects already build with GHC 8, even those with significant dependencies.

• PureScript 0.9.1 released

• Measuring GC latencies in Haskell, OCaml, Racket

  I thought it would be amusing to reproduce the synthetic benchmark in OCaml and Racket, to see how other GCs handle this.

• weigh: Measuring allocations in Haskell

  Bringing down allocations (and thus work, and garbage collection) was key to achieving reasonable speed.

• HaLVM v3: The Vision, The Plan

  Galois decided to see if using a higher-level language could help speed up the prototyping process, by porting GHC to run on Xen.

• Enterprise Haskell Pattern: Lensed Reader

  I’d like to discuss some of the techniques I’ve picked up in the hopes that other Haskellers looking to use Haskell in “enterprise” software can at least have a jumping off point.

• Why is the F# version of this program 6x faster than the Haskell one?

  I am finding it difficult to figure out how to write efficient Haskell code.
