of information about Haskell from around the web. This issue covers the
week of June 30 to July 13, 2013.

Quotes of the Week

   * monochrom: 8-bit word uses less memory, but if it doesn't have to
     preserve information, I know how to use 0 bits of memory.

   * byorgey: you know, servers migrate in the summer to their ancestral
     breeding grounds

   * emeijer: It must me said on the other hand compiler writers seem to
     ignore the existence of formal semantics completely, probably
     because they don't like greek letters.

   * byorgey: now we have the pig operator <^(++)^> as well as the robot
     monkey operator (:[])

   * chrisdone: i remember when the internet was black and white and you
     had to upload web pages back onto the internet when you were done
     with them

     that prevents them from shutting up about pure functional
     programming.
