Dear Haskellers,
the deadline for the May 2007 edition of the Haskell Communities
and Activities Report is only a few days away -- but this is still
enough time to make sure that the report contains a section on *your*
project, on the interesting stuff that you've been doing; using or
affecting Ha

Dear Helmut,
I spoke with Novel a few months ago when I was having problems with the SUSE
watcher and associated update capability with the 'old German version of Suse
10.0', they have corrected the problem, but in the long run the old 10.0 will
not be officially supported. Their product names
that is exact the way, how i had learned about the state monads like IO and
Maybe.
that was even before i understood the [] monad, folding and using Random; i
don't remember when that was... ghc-5.xx age.
in my opinion, unsafePerformIO is a good learning tool, as soon as you use it

Hi Welcome to the mailing list.
Problem with partially functional languages in my opinion is if you can
do things the way that your most use i.e. imperative programming you
will do it
Perl, Python, Lisp, Scheme and etc have features that support functional
programming but I would wager t
Phiroc,
I'm new to these ideas too--especially since my college math training
is non-existent. I found the following wikipedia articles
particularly illuminating on the topic of side-effects:

Whoa! I'd be very cautious recommending these for newbies ...

I seem to remember someone writing a book on functional programming in
Perl, which seemed odd to me.

I need some random numbers.
in the IO Monad, hiding the use of a generator
do x <- randomRIO (0, 1 :: Double) ; print x
you can also make the state explicit:
do g0 <- getStdGen ; let { ( x, g1 ) = randomR ( 0, 1::Double) g0 } ;
print x
a RandomGen is actually the state object for the ge
If this is interesting then please enlighten a poor, ignorant PERL hacker.

Hi,
I need some random numbers. The documentation identifies StdGen, but I can't
figure out how to invoke it. The documentation is great
in every way, except an actual example that I can essentially cut and paste.
Thanks

Hello,
what are the advantages of haskell over semi-functional programming languages
such as Perl, Common Lisp, etc.?
What are the mysterious "side effects" which are avoided by using Haskell, which
everyone talks about? Null pointers?
Don't you ever get null pointers in Haskell, including when
