[IronPython] Resolver One 1.4 beta - with IronPython 2.0

Current thinking is that IronPython 3k will be the 1st version that will take a dependency on .NET 4.0 so we’ll have to wait until then.  Having to rely on P/Invoke is one of the main reasons we don’t have this yet (IronPython doesn’t have any p/invokes today and we’d like to avoid them if at possible).

I know :)
I have my own C# Assembly that does mmap() on Windows/Linux with PInvoke.

I did notice though that .NET 4.0 WIll have "native" support for mmap() through System.IO.MemoryMappedFiles...
So perhaps IP 2.X will add that as well...

I should point out ahead of time that there's no mmap module in IronPython at the moment, and so memory-mapped ndarrays don't work yet -- although most of the usual numpy save/load bits do work, so you'll probably be fine (unless they're too big to fit in memory).

I can't wait to use it with NumPy.

I actually have a .NET C# assembly that does some really nasty low-level stuff like loading data from memory mapped
files and wrapping them with IList<T> :)

I can't wait to make Ironclad/Numpy blow up :)

   Hi all,

   Version 1.4 of Resolver One, our Pythonic spreadsheet, is based on
   IronPython 2.0, and includes (alpha-level) support for numpy using
   our Ironclad project.
   We're releasing the beta tomorrow: this has a few performance
   problems (which are being addressed - many thanks to Dino Viehland
   for helping with this!) but is otherwise functionally complete.
    If you're interested in trying it out, drop me a line!


   Best regards,

   Giles
