Hi,
In the toydist proposal/release notes, I would address 'what does
toydist do better' more explicitly.
A big problem for science users is that numpy does not work with
pypi + (easy_install, buildout or pip) and python 2.6.

hi,
pyaudio is pretty good for recording audio. It is based on portaudio and
has binaries available for win/mac - and is included in many linux distros
too (so is pygame).
You can load, and play audio with pygame. You can use the pygame.sndarray
module for converting the pygame.Sound objects i

Hi,
Yeah, that's what I meant. Upgrading numpy over an old install via
distutils breaks it.

Another common optimization is using the distance squared for

Hi again,
I found your numpy/core/src/py3k_notes.txt file.
I left the PY3K.txt I made in there for now, so its easy for people to
find... but will use the other file for more specific information like

into py3k_notes.txt if you

Added a numpy/compat.py file from pygame.
This defines these things for compatibility:

'unicode_', 'raw_input_']
geterror() is useful for exceptions compatible between py3k and pyv2...
As in py3k you can't do this:

Hi again,
I deleted the old git repo there, and I followed the scipy git guide
and put the changes here:

hi,
Definitely memory speed is probably the biggest thing to consider.
Also using 64bit if you need to do lots of calculations, and cache
things.
ACML is another alternative... but I've never tried linking it with numpy

Hi,
the other day I tried installing numpy with easy_install, and did not have
much luck with python2.6.
To reproduce, try installing with easy_install-2.6, or with buildout.
The work around is to just install it in another way (eg, dmg or with
setup.py install).
cheers,
