None of the lower level libraries support multithreading. If any of those

The sample program (the "active" version) here runs fine, so the OpenGL GLFW
must have been installed properly. Must be the SOE stuff causing the problem.

I got Hudak's Haskell School of Expression today and just tried a couple of the
graphics programs from the software I downloaded at the book site. Both seem to
hang on opening a window. Is there a fix for this problem? I'm on a Fedora 14

Hi all,
The new Synopsis box in the API docs expands beyond the monitor for
functions that have long signatures. An example is the TreeView
documentation [1] in the gtk package.
I have only tested Firefox.

I believe that the SDL bindings provide a way to play sounds from a
file. I know SDL works on windows, I'm not sure if the Haskell
bindings do. I've also not had to use that capability of the bindings,
so I can't speak to ease of use. However, it's something to look at.

Indeed and writing the t+1 strictly to the ioref also makes it
slightly faster (~2%):

Parsec is a monadic combinator library that is well-documented, simple
to use, and produces good error messages. Parsec is not inherently
lazy/incremental and is not well-suited to handling large quantities

Hi,
First of all, don't be fooled by the alloc statistic. That is not 3GB
memory residency, that's 3GB allocation, which was interspersed with
lots of garbage collections, in the same way that measuring how many
times malloc was called in a C program doesn't necessarily indicate
memory resid

I recently got the jack package from hackage working again. For those
unfamiliar, jack is a callback-based audio server.
Writing a client entails importing the C library or its bindings (the
Sound.JACK module in my case), creating a client and
some ports (using provided library functions), and then
Hi, cafe,
I'm interested in write a program that plays sounds in real time. There is
a library with functions able to play sounds, from a file?
I'm on Windows, and I don't need special features, only play sounds in a
comfortable way. Thanks in advance.

I am trying to load a bitmap and display it with the Xlib bindings, but I wasn't
able to find a way.
The C Xlib functions would be XReadBitmapFile() of XReadBitmapFileData() to read
the data, but it seems that those functions haven't been included in the haskell
bindings.

Yes, I don't understand that either. Is there a reason that using a weaker

why there is more of an impetus to use the crypto

Hi,
Your definition of 'unit' in the
