    that work portably across platforms.

Calls for Participation

    Primitive Haskell

    Originally this is a chapter in Mezzo Haskell, covering primitive
    operations, evaluation order and mutation. Michael Snoyman wants
    feedback on style and teaching approach.

    Intermediate Haskell documentation proposal

    Michael Snoyman points out that Haskell community lacks
    middle-weight documentation beyond the levels of RWH and LYaH,
    or it is redundant, of varying quality and hard to find.
    He proposes to create conditions that will help Haskell
    community to write this documentation collectively.
    Part of Commercial Haskell effort.

    Web development using Haskell

    A discussion of (micro)frameworks, active and (seemingly) dormant,
    and the ultimate minimalism.

    Let's teach GHC idiom brackets!

    (| pureFunction (fetchWith some params) (fetchMore withOthers) |)
    vs pureFunction <$> fetchWith some params <*> fetchMore withOthers

    Is working with numeric formulas on Haskell a pain for anyone else?

    (/) and quot have different semantics, and this makes it hard to implement formulas.

    Monads in a non Functional Programming language X Haskell

    Fluid interfaces and Monads have little in common, although it might look like a lot.

Quotes of the Week

    "would require parens" in haskell world is like saying
    "would require taking lives" (chrisdone)

    "… pure functional programming and HTTP are a match made in heaven
    (type Application = Request -> Response - it doesn't get any
    more sensible than that ;)) …" (tdammers)
