Re: [Haskell-cafe] numeric minimization in Haskell

Did I just read an admission that Sony Imageworks use Haskell for movie post-production?

Nice try, but I do not speak for Sony Pictures Imageworks. Whatever things they do or do not do in post-production would no doubt fall under some kind of trade secret thing and I would not mention them here. Kudos to you for knowing that Imageworks is a part of Sony. You must be an industrial spy! Even so, you are inferring more than I implied. By "in my work", I mean specifically that I use Haskell (and GSLHaskell) to develop algorithms, prototype them, then validate the results of production code written in C++ (and GSL). As such, I couldn't care less about efficiency in Haskell. I realize that this way of doing things may be considered "impure" to hardcore Haskellers. My full comment was actually:

GSL is written in C, and I don't know any language more portable than that! gsl_vector and gsl_matrix use a continuous block of doubles, so you can use the FFI to marshall this however you want for efficiency.

I know it's heresy on this list to treat Haskell like a wrapper over C/C++, but my experience shows that it has a lot of advantages, even if the final product is code in another language! This is the only argument for using Haskell "in the real world" that I have found has any traction with management, so I hope people don't disdain it while waiting for the day when the benefits of Haskell will be apparent to all.

I like spending my time on interesting things, not reinventing pre-debugged and efficient libraries. I use GSLHaskell in my work and have never had a problem.
