Hi everyone,
I had looked at Haskell some years ago but dropped it because there wasn't much
support for the kind of work I do, which is numerical computation. Now there's
exciting new stuff such as repa, so I decided to give it another try.
I installed the Haskell platform 2011.2.0.1 for MacOS X 10.6 and started
working through the tutorial at
http://www.haskell.org/haskellwiki/Numeric_Haskell:_A_Repa_Tutorial
Unfortunately I didn't get very far, because I am stuck at installing repa:
cabal install repa
Resolving dependencies...
cabal: cannot configure repa-2.2.0.1. It requires base ==4.4.*
For the dependency on base ==4.4.* there are these packages:
base-4.4.0.0.
However none of them are available.
base-4.4.0.0 was excluded because of the top level dependency base -any
I don't understand what this means (what's so bad about "any"?) nor do I have
the slightest clue what to do about it. There's a brief Stack Overflow
discussion about this at
http://stackoverflow.com/questions/7375719/cabal-install-dependency-error-base-was-excluded-because-of-the-top-level-de
but it doesn't provide a solution either. Any help would be greatly appreciated
- I just recall that my goal is not understanding cabal, but working with repa.
Konrad.

I guess I'll share some things that I've come across in my own
searching. This has to do with functional programming in general, not
just Haskell.
There are PLT Scheme (now Racket) people all over the US.
All of the Universities listed in the PLT Publications section have at
least one person who is very into functional programming.
http://racket-lang.org/learning.html
Look out for the Graduate Study page, Zhi-Qiang Lei, it is intended to
be funny. But there are links at the bottom to the home pages of various
faculty at universities who are involved with Racket/PLT Scheme.
http://racket-lang.org/common-plt-app.html
Someone also just sent me this link:
http://www.schemers.com/schools.html
Another way that I've attempted to search is by looking at where past
functional programming conferences have been held in the US. There is
often a faculty member interested in FP at a host university. Also it is
easy to see lists of presenters and where they are from. It is often
hard to tell whether someone is interested in FP based on their blurbs
on CS faculty web pages.
The Wikipedia page on the International Conference on Functional
Programming lists the names of various other FP conferences so it is a
good place to start.
http://en.wikipedia.org/wiki/International_Conference_on_Functional_Programming
Someone also just reminded me of this:
http://www.haskell.org/haskellwiki/Education
But it isn't very useful because it is so out of date.
Carnegie Mellon seems to be one of the US universities that are most
aggressively including FP in their instruction:
http://existentialtype.wordpress.com/2011/03/15/teaching-fp-to-freshmen/
Then of course, I've used normal Google search techniques.

There are two issues here:
(1) The latest version of repa doesn't work with ghc-7.0.3 or
ghc-7.0.4. These provide base-4.3, and base is hardwired in GHC and
cannot be upgraded. The easiest way for you to get around this is to
explicitly say "cabal install repa-2.1.1.5".
(2) Your version of cabal-install provides bad feedback (instead of
base -any it should really say that it has to be the version of base
that comes with your GHC) and fails to detect that it in fact could
just install repa-2.1.1.5. The current development version of
cabal-install fixes both problems. However, as long as the fix
suggested in (1) works for you, there's no immediate need to upgrade.
Cheers,
Andres

Should we put up some type of web page or wiki? I could host something.

CMU is one of the only places I know of that is so agressively and
comprehensively teaching FP in its normal undergrad curriculum.
However, off the top of my head here is an (incomplete, unordered)
list of other places with faculty/research groups doing things with
FP:
* Princeton
* Yale
* Harvard
* University of Kansas
* Indiana University Bloomington
* Portland State
* UPenn
In such places, as an undergrad, yes, you might have to write programs
in Java -- but if you are motivated you could get involved with
cutting-edge FP research. You will learn a lot more that way than
just having FP taught in your classes anyway! In my experience
motivated undergrads who want to get involved in a research group are
often welcomed.

With the blessing of the community, of course, it seems like this would be
good information to go onto the Haskell wiki page. People who want to know
where Haskell is taught, are very likely to want to know where other, very
similar languages are taught. We would probably have to limit to the
very-similar (SML, O'Caml, ...).
What do people think?

Are there facilities for generating nicely formatted reports from Haskell,
perhaps like the Java report generation tools?
I am mostly interested in nice tabular output from a data analysis, like the
things that Jasper does. I suppose one approach is to generate eth appropriate
Jasper XML (JRXML) from Haskell, and then process that. Any good experiences or
recommendations in this area appreciated.
