I think Haskell works nicely to combine at least the C and Perl aspects, but as far as I can tell, I'm about the only one who does this. There isn't a lot of comp.sci. in bioinformatics, beyond a handful of relatively standard algorithms. I guess it's one of those practical fields.

Which is not needed by default. 'Standard' codelets are already present in the source distribution and far enough for most uses. I have been installing FFTW on a dozen of archs over the past 10 years and I have never used the OCaml code (in fact I did it once to play with it). FFTW doesn't need any OCaml compiler or lib to be compiled and installed. No. FFTW contains around 13,000 lines of OCaml source code and you need the OCaml compiler to compile that. Yes you need a OCaml compiler to compile the OCaml code. But you don't need the OCaml code to install FFTW, except if you want to generate your own codelets which remains an exceptional case. If you don't believe me, perhaps you will believe Steven G. Johnson (one of the authors of FFTW) when someone tried to tell him that he hadn't written his software in OCaml: http://groups.google.co.uk/group/fa.caml/msg/cfd08423c22ccff5 I am not saying that the FFTW distribution doesn't have OCaml code nor this code is negligeable/useless! I just say that it is useful to build the codelet for unsupported size or to tune them for a given arch. The libfftw itself, the only part meaningful for your program performance and used by MATLAB, is entirely made of compiled C and asm code. Just to quote the doc: [ section 8.4 Generating your own code The directory genfft contains the programs that were used to generate FFTW’s “codelets,” which are hard-coded transforms of small sizes. We do not expect casual users to employ the generator, which is a rather sophisticated program that generates directed acyclic graphs of FFT algorithms and performs algebraic simplifications on them. It was written in Objective Caml, a dialect of ML, which is available at http://pauillac.inria.fr/ocaml/. ] So your assertion the FFT routines in MATLAB (FFTW: written in OCaml) is simply wrong or at least an ambiguous shortcut. MATLAB doesn't run OCaml code in its FFT routines. That OCaml code has millions of industrial users worldwide and is one of the most widely used pieces of software written in a statically typed functional programming language. And OCaml was (still is?) the language learnt by French students in the 90's in the 'classes preparatoires'. At least when I was teaching scientific computing. I am not a language fanatic, so this kind of argument is simply meaningless for me.

Re: [Haskell-cafe] Why are OCaml and Haskell being used at these companies?
well, I generally read more than post on the list, but being in investment banking ( for 20 years), this one is too hard to resist... The kind of job these guys do is highly mathematical ( quantitative analysis) as opposed to traditional banking or Back Offices where th job is (not so clever) record crunching... buying software packge also make little sense for them, because the very nature of the job is to develop new models to play around market inefficiencies, or just against competitors models... if everybody would have the same ( model, package), they would be out of business... time to market is key, reliability too , and the kind of guy they hire ( quant analyst) have the brain to learn new languages , so this is not the same problem as turning an army of cobolist into java. also, the very expressive nature of functiunal programming blends very wells with maths, better than record crunching... if you add on top grid computing and parralelism...

I really want to understand what industrial markets are adopting FPLs and why in order to help push FPLs penetration into industry. Another company is http://www.galois.com Kind regards, Vasya For the old examples that you gave, reliability was a major concern. Functional programming languages are now much more widely used in industry, primarily because they offer substantial productivity improvements (roughly 10x) over C++ and Java and, consequently, are much more cost effective. Penetration is highest in parts of industry where small groups of talented programmers get together, most notably startups. Look at XenSource, Wolfram Research, The MathWorks, Wink, Merjis, Red Hat, Linspire and Skydeck for example. -- Dr Jon D Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/products/?e ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
