Welcome to issue 189 of the HWN, a newsletter covering developments in the Haskell community during the week of June 26 to July 2, 2011. It seems that it was a pretty quiet week in the mailing list. There were no significant announcements made, and the number of threads was low by comparison. Hope everyone is having a great week! You can find the HTML version at: http://contemplatecode.blogspot.com/2011/07/haskell-weekly-news-issue-189.ht... Quotes of the Week * iwtu: [#haskell] is a good channel. Really. People are helpful and don't deserve killing or eating * [Cale] Finite dimensional vector spaces over a field F are algebras for the monad of F-linear combinations of elements of a set. [ivanm] oooohhhhh.... _now_ I get you! * [quicksilver] C++ templates can embed arbitrary computation at compile time [quicksilver] that alone tells you something about the complexity of the compiler [edwardk] yeah. they were accidentally turing complete. (whoops!) ;) [quicksilver] edwardk: OOPS I ACCIDENTALLY THE WHOLE TARPIT * bos: other companies use expensive firewalls and crypto hardware to protect their intellectual secrets. edwardk uses category theory! * ManuelChakravarty: After all, you can import any C function with a pure type which also allows you to wreak arbitrary havoc. We enable the user to disguise arbitrary machine code as a Haskell function of essentially arbitrary type. In comparison, `unsafePerformIO' seems angelic. * NihilistDandy: The best part of Haskell is that 80% of module names can be turned into clever blog titles. * AlanPerlis: We will never run out of things to program as long as there is a single program around.
