Welcome to issue 227 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers the week of May 6 to 12, 2012.
Announcements Doaitse Swierstra reminded us about the Summer School on Applied Functional Programming, at Utrech University. Hurry to check it out, as the deadline for registration is May 20th! [1] http://goo.gl/TZYdd Janis Voigtlander announced the release of the 22nd edition of the Haskell Communities and Activities Report. [2] http://goo.gl/pXIZn Quotes of the Week * dcoutts: (on #darcs): "[on github:] it's like the facebook of source repos" * dmwit: "Functional programming" is a technical term that means more than just what the two words mean separately. * Axman6: "GHC Warning: Did you see that in an OOP textbook? You probably don't want to be doing that" * StevenKaas: Haskell's Wager: what if infinite lists can suffer infinitely even when lazily evaluated? * quicksilver: "Patent covering a device for emitting greetings to the world community as a whole in computer-readable format" (US Patent no 1787528391) Top Reddit Stories * Videos to the functional programming course I attend are freely available. I thought you might enjoy them.
