2011-01-04 Thread Justin Peel
Hi all, I've been submitting some patches recently just by putting them on Trac. However, I noticed in the Numpy Developer Guide that it says: The recommended way to proceed is either to attach these files to an enhancement ticket in the Numpy Trac and send a mail about the enhancement to

[Numpy-discussion] NumPy on HPC podcast

2011-01-04 Thread Brock Palen
I host and HPC podcast with Jeff Squyres of OpenMPI fame: www.rce-cast.com We would like to have a developer or two from NumPy on the show to represent the project. We do this over phone or skype and takes about an hour. Feel free to contact me out of band. I hope to hear from you soon!

Wow, great! I'm excited to try this. I think your patch significantly increases the extendability of numpy. Is the C-API exposed currently? Can you use the API from Cython (meaning is the numpy.pxd file updated)? On Tue, Jan 4, 2011 at 12:04 PM, Mark Wiebe mwwi...@gmail.com wrote: On Sat,

Oh, and I'm not sure about Cython, since I've never looked into its details. I imagine Cython will want to short circuit some of the Python exposure code, since accessing the iterator values creates new array objects. -Mark On Tue, Jan 4, 2011 at 12:59 PM, Mark Wiebe mwwi...@gmail.com wrote:
