Are there many Haskell products? Our expertise is in scientific, numerical and graphical computing. Our product catalog should elucidate this: http://www.ffconsultancy.com/products/ I'd like to know how feasible it would be to rewrite some of these products in Haskell. For example, our time-frequency add-on for Mathematica might sell a lot better if it were a standalone cross-platform GUI application or even a web application. Is it feasible to write such a thing in Haskell? Are any core Haskell libraries non-free for commercial use? Also, would anyone be interested in a Haskell for Scientists book, following our OCaml for Scientists and forthcoming F# for Scientists books? I didn't read these books but I would if one exists on Haskell. But I expect that you will first have to convince scientists that Haskell can be efficient in numerical analysis (both memory and speed). My guess is that it can be efficient if missing efficient data structures are provided. This has been solved for strings so I guess it can be done for other data structures as well but it seems to be a huge work. If the target is only to wrap the GSL or equivalent, then I expect that it will only be considered as a curiosity. a+, ld. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Darcs users [was: New book: Real-World Haskell!]
I didn't say there weren't others, simply that I didn't know of any others (I don't just go looking for things online all the time...having a real job really gets in the way of these things)! So I wasn't really trying to disparage darcs. But here's another statistic: http://www.google.com/search?rls=enq=darcs+inurl:_darcsie=UTF-8oe=UTF-8 Results 1 - 50 of about 54,100 for darcs inurl:_darcs. (0.38 seconds) http://www.google.com/search?rls=enq=svn+inurl:svnie=UTF-8oe=UTF-8 Results 1 - 50 of about 995,000 for svn inurl:svn. (0.14 seconds) That's 54,000 pages vs. 995,000 pages. That really was more my point. (BTW, cvs is still [Results 1 - 50 of about 2,920,000 for cvs inurl:cvs. (0.17 seconds)]) I *want* people (and companies) to move to Haskell; therefore, I want to lower the entry price. The goal is to introduce a new language, not a new SCM tool. You certainly wouldn't want to leave the impression that one MUST use darcs in order to use Haskell!

The goal is to introduce a new language, not a new SCM tool. You certainly wouldn't want to leave the impression that one MUST use darcs in order to use Haskell! Fair enough. But you do not want to leave the impression that one must use SVN in order to use Haskell (or any other language, for that matter) either? Anyway, I am sure that can be avoided by a reasonable phrasing of the relevant chapter - caveat scriptor. Now, darcs is: a) really simple to get started with b) ubiquitous for Haskell programs - if you download something to install yourself, you will - as likely as not - use darcs to do the downloading. c) written in Haskell, serving as both an example of a 'real world' application, and as a possible target for the enterprising hacker. You could make a similar argument for the build system - should a Haskell book teach make instead of Cabal, just because it is more familar? -k ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
