Nick,

Hello Timothy and others,
One of my clients hosts their HTTP clients in an Amazon cloud, so even
when they turn on persistent HTTP connections, they use many
connections. Usually they only end up sending one HTTP request per TCP
connection. My specific problem is that they want a response in

Hello,
I've run into an issue that makes me think that when the GHC GC runs
while a Snap or Warp HTTP server is serving connections, the GC prevents
or delays TCP connections from forming. My application requires that TCP
connections form within a few tens of milliseconds. I'm wondering if
I'm looking at storing a data type with 7 fields in an unboxed vector,
which means that I'll have to use GenUnboxTuple to create an instance
for Unbox (a,b,c,d,e,f,g), but I was thinking that another solution is
to use instance (Unbox a, Unbox b) = Unbox (a,b) recursively to
create instance
Hello Daniel,
Did you perhaps install a newer version of bytestring or parsec?

Hello,
Up until now I've been using Aeson, but I've found that its number type
isn't going to work for me. I need to use decimal numbers while avoiding
conversions from and to Double, which Aeson doesn't allow. There are
quite a few more JSON libraries for Haskell, which all appear to use
Hi Jeremy,
Sorry if I was unclear. Rational is acceptable to me as the result of a
JSON parse, but Double (which Aeson uses), is not. Also acceptable would
be Data.Decimal.Decimal, or maybe one of the types from Data.Fixed.
JSON doesn't specify a data type for numbers, only a format.

Hello Mukesh Tiwari,
I'm wondering what happens if you replace return () with print (last
xs).

It is the third or the fourth time that somebody recently puts the
equivalence between the communication with the outer world, and side

I think there are three key concepts rumbling around in this discussion

More specifically, if I have a record type from which I construct
multiple sub-record types, and I want to store these in a collection
which I want to map over while preserving the ability to get at the
sub-fields, is there a better way to do it than to have an enumeration
for the sub-types
