itools 0.60.2 released

[J. David Ibáñez]

itools 0.60.2 (2009/06/03)
==

itools is a Python library, it groups a number of packages into a single
meta-package for easier development and deployment:

  itools.abnf itools.i18n itools.stl
  itools.core itools.ical itools.tmx
  itools.csv  itools.odf  itools.uri
  itools.datatypesitools.pdf  itools.vfs
  itools.gettext  itools.pkg  itools.web
  itools.git  itools.relaxng  itools.workflow
  itools.handlers itools.rest itools.xapian
  itools.html itools.rss  itools.xliff
  itools.http itools.srx  itools.xml

The mechanism to use a subprocess to run commands and save memory has
been generalized and is now provided by itools.core; the functions to
check are 'start_subprocess', 'read_subprocess', 'send_subprocess' and
'stop_subprocess'.

Some bugs have been fixed, including #650 and #670.

ANN: Numexpr 1.3 released

[Francesc Alted]

 Announcing Numexpr 1.3


Numexpr is a fast numerical expression evaluator for NumPy.  With it,
expressions that operate on arrays (like "3*a+4*b") are accelerated
and use less memory than doing the same calculation in Python.

On this release, and due to popular demand, support for single
precision floating point types has been added.  This allows for both
improved performance and optimal usage of memory for the
single precision computations.  Of course, support for single
precision in combination with Intel's VML is there too :)

However, caveat emptor: the casting rules for floating point types
slightly differs from those of NumPy.  See the ``Casting rules``
section at:

http://code.google.com/p/numexpr/wiki/Overview

or the README.txt file for more info on this issue.

In case you want to know more in detail what has changed in this
version, see:

http://code.google.com/p/numexpr/wiki/ReleaseNotes

or have a look at RELEASE_NOTES.txt in the tarball.


Where I can find Numexpr?
=

The project is hosted at Google code in:

http://code.google.com/p/numexpr/

And you can get the packages from PyPI as well:

http://pypi.python.org/pypi


How it works?
=

See:

http://code.google.com/p/numexpr/wiki/Overview

for a detailed description by the original author (David M. Cooke).


Share your experience
=

Let us know of any bugs, suggestions, gripes, kudos, etc. you may
have.


Enjoy!

Pyowa Meeting this Thursday

[Mike Driscoll]

 Hi,

Pyowa will be meeting Thursday, June 4th in Ames. We will be meeting
at the Ames
Public Library from 7 to 8:45 p.m. The current plan for the meeting is to
have a code review of sorts on some member submitted GIS-type code. Then we
will have a short presentation on one of the modules from Python's standard
library. Whatever time is left over will be used for socializing and
planning the next meeting. If you have ideas or would like to present
something, please let me know at the meeting or through email.

In other news, you can see my experiments in recording some of our meetings
here: http://pyowa.blip.tv/

Please note that if you don't have a fast internet connection, then you will
be disappointed as it will take eons to buffer. Let me know if you plan to
come to the meeting. Thanks!
