i recently found the convertible package

convert :: Convertible a b = a - b

However, that would make these libraries unusable with alternative

I removed unsafePerformIO, changed copy to have type Vector Double - IO
(Vector Double) and
modified benchmarks like this:
bench C binding $ whnfIO (copy signal)
I see no difference - one benchmark runs fast, remaining

Greetings,
I am pleased to announce a Haskell client library for RethinkDB[1].
RethinkDB[2] is a newly released, open source, distributed database.
Its simple yet powerful API seemed well suited to be accessed from a
language like Haskell. This haskell library is modelled upon the

Hi all,
It seems the Quasiquotation page on HaskellWiki
http://www.haskell.org/haskellwiki/Quasiquotation
has fallen behind the actually Quasiquotation implementation that
is in ghc-7.4.2 and later.
Specifically, the QuasiQuoter constructor that the Wiki takes two
parameters:

RI is a very easy using tool that search and show the documents of ruby
modules/functions, etc.
Using RI, I could get help when programming with a few commands. Quick and
simple.
And with RI backend (libs), I could also simply integrate ri to my IDE
(like one hotkey to show function summary).
So
Because I see there are many preferences on what IDE to use for Haskell

Have you tried Hoogle? I know you can install it locally and use it from
GHCi or Emacs. I'm not familiar with ri, but from your description I think
a local Hoogle would serve the same purpose with the added benefit of being
able to search by types.
Here's the wiki page about it:
