Dear list,
list comprehensions and SQL-like generalized comprehensions can be used to
write queries in
Haskell. Does anyone know of any work focused on optimizing such queries? A
quick google didn't
show up anything meaningful.

See http://hackage.haskell.org/package/DSH. Queries generated by this
library are fed through the Pathfinder query optimizer.

Dear All,
Data visualization for hMatrix is basically my main objective, but I would
like to be flexible in the following ways:
* Have generic approach so other data types can be visualized with my
library as long as the necessary instances are present.
* Define a generic standard to represent

Hi, I am a Computer Science student from Argentina. I am interested in
working this summer on some project related to Haskell for the Google
Summer of Code. I have learned a lot about this, because in my career, we
have a special approach in functional programming. So, I would like to know

I've been struggling with a similar situation: a client and server that
communicate with binary-encoded messages, sending heartbeats (dummy
messages) every 30 seconds, and timing out the connection if no response is
received in 3 minutes. The client sends data to the server, while also
listening
Hi list!
I want to use MVectors in a StateT monad transformer.
How do I do that? StateT isn't a member of 'PrimMonad', and I have no idea
how to make it one.

You can use Control.Monad.Trans.lift to lift the PrimMonad
The monad my code is currently written in is:
type MC = MCT Identity -- where MCT is the monad transformer version of it.
I have two options for threading state through this:
MCT (ST s) a
StateT s MC a
The first option would work if I had some function with the signature
MCT Identity
