ANN: Numexpr 1.3 released

========================
 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.

itools 0.60.2 released


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.datatypes        itools.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: Resolver One 1.5 released (corrects previous message)

We are proud to announce the release of Resolver One, version 1.5.
Resolver One is a Windows-based spreadsheet that integrates Python
deeply into its recalculation loop, making the models you build more
reliable and more maintainable.

For version 1.5, we've added a console; this new command-line window
gives you a way to interact with your spreadsheet using Python
statements.  Here's a screencast showing why this is worth doing:

    <http://www.resolversystems.com/screencasts/console/>

We have a 31-day free trial version, so if you would like to take a
look, you can download it from our website:

    <http://www.resolversystems.com/download/>

If you want to use Resolver One in an Open Source project, we offer
free licenses for that:

Python svn builds

Python svn build (http://pyvm.sourceforge.net) is a project to create binary 
distributions for the python interpreter: the source used to build them is the
latest svn revision. 

The builds are made using the OpenSUSE buildserver https://build.opensuse.org
and the test results can be seen on the website http://pyvm.sourceforge.net.

The final packages in rpm format are available for CentOS/Fedora/Mandriva and 
OpenSUSE.
