Welcome to issue 313 of the HWN, an issue covering crowd-sourced bits

of information about Haskell from around the web. This issue covers

from November 16 to December 6, 2014

Quotes of the Week

   * Dijkstra: How do we convince people that in programming simplicity

     and clarity (in short: what mathematicians call "elegance") are not

     a dispensable luxury, but a crucial matter that decides between

     success and failure?

   * Dijkstra: Simplicity is a great virtue but it requires hard work to

     achieve it and education to appreciate it. And to make matters

     worse: complexity sells better.

   * monochrom: those who have learned from history are bound to

     helplessly watch other people repeat it.
