Hi all,
I have the following program, which I'm running using runghc 7.4.1
with HP2012.2 on Windows 7:
==
{-# LANGUAGE OverloadedStrings #-}
module Main where
import Network.Socket hiding (send, sendTo, recv, recvFrom)
import Network.Socket.ByteString
import qualified Data.Text as T
import
this works fine; the messages are received by the
server. It also works if I run the sendMsg program on a Linux VM which lives
on a separate IP.
So it seems that it's not a general bug but rather a problem with your
setup, possibly a firewall.

Hi all,
I
http://hpaste.org/69885
The warning in that paste occurs when I attempt
$ cabal update
$ cabal install cabal-dev
This is curious because it wants to install a previous version of mtl.
I can't figure out why. There doesn't seem to be any dependency
between cabal-dev and mtl. According to hackage,
For reference to anyone coming across this:
The issue is that cabal-dev does in fact depend on the old mtl, if one checks
the cabal file. (Thanks to dcoutts_ on #haskell).
The suggestion I received was to use virthualenv.

Hi all
After glancing through the haddock documentation and some googling, I
can't tell if there's a supported
way to link to a section heading in haddock documentation. Is there?
Thanks,

And after a lot more sleep and some digging, it turns out that the
build script was forcing GCC to build the .o file as a 32 bit binary,
and thus causing the magic mismatch.

Is there any other way of implementing external behaviors besides that?

I'm currently just getting into playing around with concurrency in
haskell, primarily because I find STM intriguing. In looking through
the docs I noticed that the transactional channels are GHC specific.
I'd be very much interested in working on this library for GSoC. I'm
currently working on an idea for another project, but I'm not certain
how widely beneficial it would be. The preprocessor and
pretty-printing projects sound especially intriguing.

I would like to write an audio interface for haskell for GSoC. The
idea is to have a simple frontend (possibly an analog to the IO
'interact' function) that would permit writing simple functions to
process audio. The interface would permit easy usage of various audio
APIs on various platforms to
I've missed? Things you'd do

it's such a big undertaking.
Thanks,
