Thu Jul 18 02:52:51 CEST 2013

Welcome to issue 273 of the HWN, an issue covering crowd-sourced bits
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

   * raganwald: Immuteability: The property of functional programmers
     that prevents them from shutting up about pure functional
     programming.
