[8] http://goo.gl/dDYrl Quotes of the Week * kmc: when computer scientists rebuild the world after the apocalypse, we will have hanging gardens with trees that grow downward * kmc: a wise man once said that the entire world can be described as convex combinations of drugs, math, and cardboard * roconnor: as a rule of thumb, avoid any packages shipped with the Haskell Plaform. * kmc: Try the new GHC IO Scheduler! It's got what plants crave! * kmc: I refuse to believe that any loving god would invent the monomorphism restriction * AlanPerlis: It is easier to write an incorrect program than understand a correct one. * [kmc] do you have a theory where the stack overflow is coming from? [copumpkin] joel spolsky * @faq is it possible to find things Haskell can't do? [lambdabot] The answer is: Yes! Haskell can do that. * kmc: Haskell isn't really designed by mathematicians. it's designed by people who programmers would consider to be mathematicians and mathematicians would consider to be programmers Top Reddit Stories * "I'm very tempted to want to move to a functional programming language.
