Dear list,
I'm using STUArray in some of my time critical number
crunching code. I would like to know some way to catch the
exceptions raised in the ST monad, ie. ArrayException.
Looking through the Control.Exception module, I understand
that those functions can only be used within IO monad. So

Hello Adam,
After taking a closer look, the network module does do the ntohs() FFI call:
http://haskell.org/ghc/docs/latest/html/libraries/network/src/Network-Socket.html#PortNumber
Thus, I think the issue is probably that Scott's UDP Client does not do the
htons() for the port number, or if the

Hello Adam,
Maybe you could use the binary package [1] to always encode the portNumber,
etc. in network byte order? Such as available put/get functions:
putWord16be :: Word16 -> Put
Hope this helps...

Adam,
This does the trick, thanks! I certainly would not have been
able to track down such an insidious `issue' without much
agony and despair.

So this is a long standing, ah, issue with the Network modules.

Hi all,
I'm trying to do some standard socket stuff using the
Network.Socket library. This example is a UDP server:
import Network.Socket
proto_udp :: ProtocolNumber
proto_udp = 17
port = 10162
main = do s <- socket AF_INET Datagram 17
bindSocket s (SockAddrInet (PortNum port) iNADDR

What do you mean by parallel programs? The parallelism hints used by
ghc? In that case, I'll be supporting whatever the pars

Will you be considering parallel programs? Also, perhaps some
information flow analysis would be interesting.

Sometimes, it's not obvious where to draw boundaries between modules,

Hello All,
Emping 0.4, a utility which can derive heuristic rules from facts in
Open Office Calc spreadsheet .csv format, has been released on
HackageDB.
Version 0.4 supports blank fields, treated as 'none of the others',
which allows for split attribute values. For example, "Owns Car" could
