[Haskell] Haskell Weekly News: Issue 244

Thu Sep 20 03:36:14 CEST 2012

Welcome to issue 244 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of September 9 to September 15, 2012.

As you might have heard, GHC 7.6.1 is out for all platforms. I would
say "get it while it is still hot", but I guess I missed my opportunity
to do that last week.

Sonke Hahn wrote in to announce that on Monday "Story Episodes of
Nikki and the Robots" was was released.

Malcolm Wallace has uploaded videos from ICFP 2012, for those of us
that didn't have the opportunity to be there. Big thanks for sharing
these with the community!

 Quotes of the Week

   * copumpkin: when in doubt, blame ski

   * shachaf: You can call the greengrocer and place an order. That'll
     convert their unordered pears into ordered pears!

   * shachaf: Those who would give up essential type independence for a
     little temporary type safety deserve neither independence nor
     safety.

   * ddarius: edwardk: So your plan for Haskell adoption is to write
     Haskell in languages that aren't Haskell, say "Man, these languages
     suck, this would be super easy in Haskell", and then use the
     Haskell you started with reproducing functionality at an
     "unbelievable" rate.

   * cmccann: personally I'm just waiting for an extension that demotes
     types to the value level, so that we can finally have natural
     numbers.
