The reason for mirror was avilability, yes, and when the signatures were

packages from mirrors, when they were not available.
But now if the signatures were generated by the uploader, then the morrors

Hi Vincent,
I got it to work :) But there seems to be some bugs in the Haskell
server certificate handling. It seems that TLS do not transfer the ST
(state, as in California) parameter in the X509 subject field. It also
seems that the Haskell server do not send the email-address.

Hi,
I want to use dph (data parallel haskell) for a presentation.
(Nothing fancy, just compile and run some demos.)
What ghc version should I use and where do I get it?
I read the advice use HEAD but when I build
from the 7.1.20101213 source snapshot,
dph is not installed (should it be?)

Hi,
Is there something like an identity type, transparent to the type-checker, in
haskell ?
For instance, I'm defining an interval arithmetic, with polynomials, matrices,
and all that... defined with intervals. The types are :

Hello,
while building GUIs using Gtk2HS I always struggled with the following
question: how to sync the state of the GUI with the state of the rest
application. I usually make several IORefs store the state there. But
it's quite easy to forget to update relevant parts of GUI when state
Hi Haskeleers,
I got a working SSL server using the TLS package. Great. However, I
really intended to use SSL for an asynchronous server. That is, the
server must constantly listen for a client message, which may result in
zero or more messages send _to_ the client. And the server will, without

Hi Peter
I beg your pardon? I didn't say anything about 32M. I said that
designing software to rely on a GHC-enforced memory limit as a means of
dealing with infinite loops feels really not like a particularly good
solution.
As I understand the discussion, it's not about infinite loops.
Maybe I'm missing something - but shouldn't the code listening on the
Handle already be in it's own thread?
The general recipe is:
1. Bind a socket to port
2. Call Network.accept, then take the resultant Handle, call forkIO
with the TLS actions and the resultant handle. Go back to 1.
So even

It seems to me that a general SSL implementation should not preclude

months old and one can already use it for SSL servers and clients,
Ok, I think, I made it right now. I wrote two versions of the very same
module with roughly the same interface. It is minimalistic framework for
producing, transforming, zipping and folding streaming data (a sample
code that does file IO provided, but it is not well tested yet). One

Fail can't just be removed. That would just break too much code. For
example, I find myself writing code like the following:
[a,b,c] - Just someList
in place of
let [a,b,c] = someList
so that pattern match failure is lifted into the maybe monad (as
long as I'm already in the maybe monad).
