[Haskell-cafe] Haskell Weekly News: Issue 189

Thu Jul 7 04:14:01 CEST 2011

   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!

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.
