Hi all
I created the beginnings of a simple circuit simulator using haskell.
It can be downloaded
from.

It uses a modified version of the haskell DSP library matrix. I
extended it with a simple pivoting
Its not very haskelly, but
Dear Group,
If any of you are struggling with understanding monads, I've tried to put
together a pretty through explanation of what is behind the Reader monad. If
you're interested, have a look at:

Enjoy.

Hi guys,
is there a mailing list for haskellers that defected to F#?
Not that I was I going to, just asking, absolutely hypothetically. Uhm.

Hi Günther, I would be interested in one too. I'm a Haskeller
currently working for an F# shop. There's hubFS but I would absolutely
prefer a mailing list. --A

Hi Anton,
cool I'll keep you in the loop.
Would you mind talking about more about what you do in the F# Shop?
I must admit I only came to haskell itself only 2 years ago, created 2
apps in it and have no clue for instance on how F# standing in the
market is.

There are a couple problems with this. First, the storage layout for a

The Cal3D for Haskell project provides a partial binding to the C++ Cal3D
animation library. The project homepage is

There are three packages available on hackage:

I am somewhat new to haskell. It is amazing that I can actually write
a CGI program using Network.CGI without really being comfortable with
the Haskell type system. Especially when it involves monad
transformations.
So I decided that I better understand this. I looked at the Practical

I ran into a unfortunate syntax error just now. I figured I'd share
it because it's the weirdest message I've ever gotten out of ghc. The
broken code is

Right, the where terminates the entire expression, you can't use it
in the middle like that. I'm pretty sure that's mandatory per the
standard, and nobody really wants to
Max - I was thinking about how to drive my new shell tests with your
framework. I have:
data ShellTest = ShellTest {
filename ∷ String
,command ∷ String
,stdin∷ Maybe String
,stdoutExpected ∷ Maybe String
,stderrExpected ∷ Maybe String
PS - not cabalised, not even committed, but here's my shell test runner for
folks to play with:

Thanks for the help previously received, but I still cannot seem to get
on top of this. The types for the constructor K will not resolve and
I'm at a loss to work out what to do with it. If anyone can offer
a further explanation and help I would be very grateful.
