When I turned on "-Wall" knob at compile time, I got a message:
Warning: Module `System.Cmd' is imported, but nothing from it is used,
except perhaps instances visible in `System.Cmd'
To suppress this warning, use: import System.Cmd()
Then I did four experiments as
I did not use -split-objs.
This option did help after I tried it. Thanks.

Just curious if Haskell can or will generate cross-platform executable code,
e.g., generate code for Linux from a Windows machine.
Thanks,

Good libraries are not enough for a language to go beyond mere existence.
There must exist good documents, i.e., good tutorials, good books, and good
explanations and examples in the libraries, etc, that are easy for people to
learn and use. In my humble opinion, Haskell has a lot of libraries, but
A Cook Book is good but relies on people specifically working on it. I think
most of the package authors submit their packages because they themselves
need the modules in his real world.
I think package authors adding examples in the Descriptions section is a
good start when they submit their pack
Hi,
I got an error if one of lines reads "--++ bla bla bla" where I tried to
comment, but "-- ++ bla bla bla" (notice the space after "--") is OK.
Do you think this revealed a tiny bug in the GHC compiler (I am using
Windows Haskell Platform 2009.2.0.2)?
Thanks,
Hong

The question is more about algorithm than Haskell. But I am going to code in
Haskell which I am still learning.
Suppose I have a large table, with hundreds of columns and thousands of
rows. But not every cell has a value (of String, or Int, or Double type).
I want to shuffle the rows to maximize
Thanks. I actually prototyped in Perl the SA method intuitively (though I do
not know its name). But it is way slow. So I want to improve the speed by
means of both algorithm and language.

Hi Casey,
Thanks very much for your zeal.
The table is a csv file. Actually the number of rows can be sixty thousand.

Hi Dear Haskellers,
I have this small program to grep recursively in parallel. It works fine,
but generates the last line empty. Is this empty line coming from
mapConcurrently()?
Thanks,

I had similar work situation before. What I did was: install a CentOS
virtual machine on Windows at home (CentOS version should be compatible to
your RHEL5 version, and do not update it), then play with Haskell within
CentOS. Your executables will be runnable on RHEL5.
