Hi, How I can do this: int(scipy.comb(20314,117)) ... OverflowError: cannot convert float infinity to integer

I assume you mean `scipy.misc.comb`. If you give `comb` the argument `exact=True`, it will give the exact result as a Python long integer:

comb(20314, 117, exact=True) 185322125435964088726782059829379016108985668708943661610691107922797953622540795237396216566443123945647349065209794249915331405960154995668715672694861752881279482861934217563789733636501993781318815128638676831358831027763891670979664077780116887804168965068781398413964827499948504201570364142600031022445600L

By the way, scipy questions like this should be asked on the scipy-user mailing list: mail.scipy.org/mailman/listinfo/scipy-user (although I can't seem to connect to that site at the moment). Warren

Hi all,

Building binaries for releases is currently quite complex and time-consuming. For OS X we need two different machines, because we still provide binaries for OS X 10.5 and PPC machines. I propose to not do this anymore. It doesn't mean we completely drop support for 10.5 and PPC, just that we don't produce binaries. PPC was phased out in 2006 and OS X 10.6 came out in 2009, so there can't be a lot of demand for it (and the download stats at http://sourceforge.net/projects/numpy/files/NumPy/1.7.1/confirm this).

Furthermore I propose to not provide 2.6 binaries anymore. Downloads of 2.6 OS X binaries were <5% of the 2.7 ones. We did the same with 2.4 for a long time - support it but no binaries.

So what we'd have left at the moment is only the 64-bit/32-bit universal binary for 10.6 and up. What we finally need to add is 3.x OS X binaries. We can make an attempt to build these on 10.8 - since we have access to a hosted 10.8 Mac Mini it would allow all devs to easily do a release (leaving aside the Windows issue). If anyone has tried the 10.6 SDK on 10.8 and knows if it actually works, that would be helpful.

Any concerns, objections?

Cheers, Ralf

P.S. the same proposal applies of course also to scipy
