--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20081004 Issue 88 - October 04, 2008 --------------------------------------------------------------------------- Welcome to issue 88 of HWN, a newsletter covering developments in the [1]Haskell community. An extra-short HWN this week, so you get an extra ten minutes to do something else during the time you would have normally spent reading the HWN! HWN-editor-approved activities for your ten minutes include eating cookies, playing [2]Fantastic Contraption, and writing a type checker in the type system while eating cookies. Announcements Arch Haskell News: Oct 4 2008. Don Stewart [3]sent out the newest Arch Haskell news --- now with 609 Haskell packages! Announcing OneTuple-0.1.0. John Dorsey [4]announced the release of the ground-breaking [5]OneTuple library, which adds the long neglected one-tuple to Haskell. It also turns out that the denizens of Haskell-cafe are completely unable to refrain from turning jokes into long-winded technical discussions about strictness and lifted types. Haskell protocol-buffers version 0.3.1. Chris Kuklewicz [6]announced the release of [7]protocol-buffers 0.3.1, with some functionality also split off into [8]protocol-buffers-descriptor and [9]hprotoc. The 'hprotoc' compiler for proto files to Haskell source code now takes a "-u" command-line option. When given, this turns on code generation to support loading, storing, and saving unknown fields. Discussion Stacking monads. Andrew Coppin began a long [10]discussion on monads, monad transformers, Applicative, MonadPlus, and related topics. planning for ghc-6.10.1 and hackage. Duncan Coutts began a [11]discussion on how to make the transition to GHC 6.10 as painless as possible, especially as it relates to the new base-4 package and Cabal. Proposal #2629: Data.List: Replace nub; add nubOrd, nubInt, nubWith. Bart Massey [12]proposed refactoring nub into a 'nubWith' function which can be specialized to efficient versions for Int and Ord. Blog noise [13]Haskell news from the [14]blogosphere. * Luke Palmer: [15]Laziness and the monad laws. Luke explains why making a Functor or Monad instance too lazy can be just as bad as making it too strict. * Paul R Brown: [16]The Haskell Platform and Lessons Learned Elsewhere. * Eric Kow (kowey): [17]darcs weekly news #6. * Mads Lindstroem: [18]Overlapping Instances in Haskell. * >>> Bill Six: [19]Dabbling with Haskell. Bill explores palindromic pangrams using Haskell. Quotes of the Week * ozy`: [on RWH] most authors are like "FUNCTIONAL PROGRAMMING IS FUNCTIONAL!!!" whereas these guys are more like "yeah but practical programming is practical. map wash_dish dishes" * BMeph: * wants an "Everything I know about computing I learned from sigfpe" T-shirt * OlegFacts: Oleg can evaluate bottom. With his fists. * quicksilver: my computer starts to play 'Dies Irae' when shapr gets ops, automatically.
