Issue 150 - February 22, 2010
---------------------------------------------------------------------------
   Welcome to issue 150 of HWN, a newsletter covering developments in the
   [1]Haskell community.

   From the very pits of Harddrive failure I return... The Haskell Weekly
   News Reborn! Last week, on friday, my HWN machine suffered what can
   only be appropriately named a unbelievably poorly timed hard drive
   failure, hence the lack of an HWN. I trumphently return this week with
   a megaedition. Tons and tons of awesome stuff happened in the last two
   weeks. So I won't make you wait any longer, haskellers, your Haskell
   Weekly News!

Quotes of the Week

     * fasta: And by cool, I mean 'that is not supposed to happen'.
     * uncyclopedia: Calculations which are undefined are denoted by the
       _|_ symbol, pronounced Bottom, which the documentation explains as
       the compiler giving you the finger.
     * Draconx|Laptop: mathematics is the art of finding different ways to
       write "therefore".
     * medfly: Cale, #haskell wants to know all your personal preferences
       so we can all copy you
     * Cale: Gentoo is a massive waste of electricity.
     * hobophobe: So, I can only conclude that Haskell is a memetic virus,
       and monads are the eggs it lays out in innocent programming forums
       to entice others to become infected.
     * benmachine: unsafeCoerce is just a generalisation of id
     * jmcarthur: what good is a state monad if your state is basically 'i
       have no idea what the hell my state is'?
