My virus scanner thinks StartProcess.exe is infected. I was hoping someone 
could post a valid cksum for it so I could compare. Thanks - Tim

Thanks Felipe Lessa for shortening the code :) and everyone for advice.

I have recently started learning haskell from the book
Learnyouahaskell - www.learnyouahaskell.com - I am done with the book except
for Bytestreams and randomness. Was trying to put my haskell skills to use
on the problems of this kind. My aim is to understand and practice haskell
and not WIN these code golf competitions! . So, please suggest me what are
the other books i can read ( and work through :) ), in general any good open
source projects to involve in, etc.. basically any advices to improve as a
haskell programmer.

Thanks in advance.

May I toss in:

main = getLine >>= print . (2 ^) . length . filter (`elem` "TDLF")
  >> main

(60 non-whitespace characters)

Subject: [Haskell-beginners] Working with System.Timeout in Windows
To: [email protected]
Message-ID:

Content-Type: text/plain; charset="utf-8"

Hi Guys,

I have been trying to do something with timeout of the System.Timeout but It
hasn't work in Windows. When I first built, it didn't work, so I went to
#haskell, and they told me that I should use -threaded, then after
recompiling with -threaded it didn't work either. Does someone one what
could probably be going on ?

I'm using it with simpleHTTP of Network.HTTP, basically what I want to do is
trying to get a source, but stop trying if I don't get an answer between a
certain amount of time, something like:

  r <- timeout timeOutTime $ simpleHTTP req

With curl for example I could use CURLOPT_TIMEOUT ( in Linux ), but I
haven't found a way to say something like that using simpleHTTP.

Cheers,

Adolfo
