Welcome to issue 279 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers the week of August 25 to September 7, 2013.
Quotes of the Week * dmwit: I typically figure a parse error on line 500 means I have 500 lines to inspect. * bos: bah, all you category wonks spoil the atmosphere. we were simple peasants, and proud, once. * merijn: edwardk's delegation has reached the point where he can have the language implementor explain his libraries... * ReinH: haasn asks an offhand question. edwardk wrote a thesis on it. * JaffaCake: children are automatically killed if their parents die for any reason * geekosaur: if the platform is batteries included, lens is a full fledged transformer robot included :) * FreeFull: Mathematical laws are so much nicer than legal laws * twey: to edwardk, v. to be working on a larger problem and absent-mindedly spin out a package to satisfy dependencies, accidentally solving the problem more elegantly than existing solutions (but perhaps incomprehensibly to anyone who can't dualize in their head) * elliott: lens is the DLC expansion pack for Haskell * monochrom: new catchy thing to say: an IORef Int contains an Int in the same sense as an IO Int contains an Int Top Reddit Stories * Announcing GHC iOS Domain: self.haskell, Score: 259, Comments: 52 On Reddit: [1] http://goo.gl/28XFCH Original: [2] http://goo.gl/28XFCH * The Haskell Cast: Episode 1 - Edward Kmett on Lenses Domain: haskellcast.com, Score: 101, Comments: 35 On Reddit: [3] http://goo.gl/umnk1Y Original: [4] http://goo.gl/0vKtZ5 * The Haxl Project at Facebook (slides from my talk at ZuriHac) Domain: github.com, Score: 97, Comments: 76 On Reddit: [5] http://goo.gl/1nWvfs Original: [6] http://goo.gl/pWk1Ll * Haskell on the Daily WTF Domain: thedailywtf.com, Score: 96, Comments: 14 On Reddit: [7] http://goo.gl/kJs9FG Original: [8] http://goo.gl/qdM3sz * Cabal 1.18.0 released Domain: groups.google.com, Score: 92, Comments: 30 On Reddit: [9] http://goo.gl/QbNCmx Original: [10] http://goo.gl/OtYTZG * I've got functional curse.
