Subject: [ANNOUNCE] python-gtkmvc 1.99.0
Message-ID: <1238580253.26044.56.camel@asia>

	Version 1.99.0 of pygtkmvc has been released. 

Project homepage:
<http://apps.sourceforge.net/trac/pygtkmvc/wiki>

Download:
<http://sourceforge.net/projects/pygtkmvc/>


==============
About pygtkmvc
==============

pygtkmvc is a fully Python-based implementation of the
Model-View-Controller (MVC) and Observer patterns for the PyGTK2
toolkit.

MVC is a pattern that can be successfully used to design and
develop well structured GUI applications. The MVC pattern
basically helps in separating semantics and data of the
application, from their representation.

The Observer pattern helps to weaken dependencies among parts that
should be separated, but need to be connected each other.

pygtkmvc provides a powerful and still simple infrastructure to
help designing and implement GUI applications based on the MVC and
Observer patterns.

The framework has been designed to be:

* Essential and small, it does only what it was designed for.
* Not an external dependency for your application: it fits in
   80KB and can be released along with it.
* Easy to understand and to use; fully documented.
* Portable: straightly runs under many platforms.

====================
About release 1.99.0
====================

Released version 1.99.0

This is a major release that breaks backward compatibility with the
1.2 family.

Also, this version is not stable yet, as there might be some changes
in the forthcoming releases toward version 2.0.0.

* New features
  Features 1 and 2 cause this version to be no backward compatible.
  
  1. View's constructor no longer takes a controller.

  2. Controller's constructor takes a view.
     This allows (together with 1.) to have multiple controllers
     controlling a shared view, making possible to decompose
     controllers (see the website for details)

  3. Support for SQLObject (support for SQLAlchemy delayed to 1.99.1)

  4. Support for custom observable properties in Models.
     Now it is possible to define observable properties whose values
     are stored outside the model, in a DB, a file, a network, etc.

  5. New syntax for defining observable properties.
     Now class attributes are used as in common ORMs.

  6. Explicit declaration of observing methods into observer through
     decorators.

  7. Views have attributes 'glade' and 'top' to simplify their
     construction.

  8. gtkmvc has now its own logging system that users can set when
     required. Previous naive prints have been removed. 

* Documentation
  1. New website
  2. New Quick Start Guide
  
* Refactoring, Bug fixes
  1. Improved performances
  2. Cleaned up View construction, that is now much more simple
  3. Fixed a row of minor bugs

Thanks to those who provided feedback and bug reports.

Subject: PyOpenGL Release 3.0.0 (final)
Message-ID: <49D3E128.8060805@vrplumber.com>

PyOpenGL is the traditional OpenGL binding for the Python language 
(Python 2.x series).  This release is the first major release of the 
package in more than 4 years.  PyOpenGL 3.x is a complete rewrite of the 
PyOpenGL project which attempts to retain compatibility with the 
original PyOpenGL 2.x API while providing support for many more 
data-formats and extensions than were wrapped by the previous 
code-base.  It attempts to retain the "easy" approachable API of the 
original PyOpenGL bindings, focusing more on ease of development (both 
for client code and the library itself) than speed.

Build and installation has been dramatically simplified.  It is possible 
to work directly from a PyOpenGL bzr branch or to merely unpack the 
package into your PYTHONPATH.  To install from source and/or participate 
in development:

    bzr branch lp:pyopengl
    bzr branch lp:pyopengl-demo

then add the pyopengl/OpenGL directory to your PYTHONPATH.  You can also 
download the source distributions from:

    http://pyopengl.sourceforge.net

and use standard distutils commands to install.  PyOpenGL 3.x is already 
supported by the PyInstaller "exe" packaging utility, and can be made to 
work with Py2exe with inclusion statements.

PyOpenGL may be installed using the easy_install script if desired.  
There are no setuptools/package-resources dependencies in PyOpenGL 3.0.0 
final.  You can install PyOpenGL on supported platforms (currently 
Linux, Win32 and OSX) with the following if you have setuptools, PIL and 
Numpy installed:

    easy_install PyOpenGL
    easy_install PyOpenGL-Demo

You can then run the scripts in the PyOpenGL-Demo package.

PyOpenGL 3.x introduces package-level configuration flags which allow 
you to modify the behavior of the entire PyOpenGL package, e.g. by 
introducing extremely verbose logging, or turning off all error-checking 
to improve performance.  Of particular note is a flag which allows you 
to disable APIs which have been deprecated by the ARB in OpenGL 3.0.  
Other flags allow you to control the trade-off between ease-of-use and 
performance during the development and release process.

PyOpenGL 3.x provides access to the entire OpenGL 3.0 API, as well as 
most extensions which have been entered in the OpenGL extension 
registry.  Commonly used extensions can have "Pythonic" wrappers written 
easily, and many of the commonly used extensions already have simplified 
APIs provided.  It also provides wrappers for the GLUT, GLE and GLX 
libraries.  The AGL and WGL modules are not provided with PyOpenGL 3.x, 
as most devs are using window-manager-based GL operations.

PyOpenGL 3.x provides a simple plug-in API that allows you to write 
data-format or platform plugins.  These can be used to easily add 
"native" support for your array-friendly data-formats (vector classes 
and the like).  There is a sample data-format plug-in which wraps the 
"Vertex Buffer Objects" extensions (in the OpenGL/arrays/vbo.py module).

PyOpenGL 3.x's documentation has been regenerated and the build process 
for the documentation has been updated so that it can be easily 
regenerated to include pointers to other Open Source PyOpenGL project's 
online code viewers.  If you would like to add your project to the list 
of referenced projects, please contact the author with details of your 
code viewer's url, code license and project name.

Notes in the reference documentation indicates the deprecated entry 
points for OpenGL 3.0.  If you have a PyOpenGL code-base you should be 
looking at reworking the code in order to eliminate the use of "legacy" 
APIs before OpenGL 3.1 drivers become mainstream.  At minimum you should 
be converting away from per-vertex operations and the use of display 
lists toward using array-based geometry.

You should expect a performance decline with the use of PyOpenGL 3.x 
versus PyOpenGL 2.x!  PyOpenGL 3.x will have an accelerator module 
released in time to provide better performance, but the development 
method (ctypes) is inherently slower than the C (SWIG) method previously 
used.  If your code is performance critical you should likely use the 
accelerator module when it becomes available.  Also consider using the 
package-level configuration flags to remove "support" functionality as 
you near release, use of these flags can provide more than 2x speedup in 
most cases.

The 3.0.0 final release has a few bugs fixed from the previous 3.0.0c1 
release.  Users of the release candidate should upgrade.  PyOpenGL 3.0.0 
is intended for use with the Python 2.x series, porting to Python 3.x is 
not currently on the roadmap.  There will likely be a PyOpenGL 3.0.1 
release in the near future which will introduce a few more optimizations 
and likely will be synchronized with the first public release of the 
accelerator modules.

Since the release of PyOpenGL 2.x another common OpenGL binding for 
Python has become popular and may be an appropriate choice for your 
projects.  The Pyglet project (http://www.pyglet.org) has a full OpenGL 
binding in "raw" C style, along with many higher-level utilities to aid 
in the development of games, all of which can be easily installed on 
common platforms.

Enjoy yourselves,
Mike

Message-ID: <1afaf6160904041613t4bb44976x65d7a4d4a90f2c47@mail.gmail.com>

On behalf of the Python development team, I'm thrilled to announce the second
alpha release of Python 3.1.

Python 3.1 focuses on the stabilization and optimization of features and changes
Python 3.0 introduced.  For example, the new I/O system has been rewritten in C
for speed.  Other features include an ordered dictionary implementation and
support for ttk Tile in Tkinter.  For a more extensive list of changes in 3.1,
see http://doc.python.org/dev/py3k/whatsnew/3.1.html or Misc/NEWS in the Python
distribution.

Please note that this is an alpha releases, and as such is not suitable for
production environments.  We continue to strive for a high degree of quality,
but there are still some known problems and the feature sets have not been
finalized.  This alpha is being released to solicit feedback and hopefully
discover bugs, as well as allowing you to determine how changes in 3.1 might
impact you.  If you find things broken or incorrect, please submit a bug report
at

     http://bugs.python.org

=========================
NumPy 1.3.0 Release Notes
=========================

This minor includes numerous bug fixes, official python 2.6 support, and
several new features such as generalized ufuncs.

Highlights
==========

Python 2.6 support
~~~~~~~~~~~~~~~~~~

Python 2.6 is now supported on all previously supported platforms, including
windows.

http://www.python.org/dev/peps/pep-0361/

Generalized ufuncs
~~~~~~~~~~~~~~~~~~

There is a general need for looping over not only functions on scalars but also
over functions on vectors (or arrays), as explained on
http://scipy.org/scipy/numpy/wiki/GeneralLoopingFunctions. We propose to
realize this concept by generalizing the universal functions (ufuncs), and
provide a C implementation that adds ~500 lines to the numpy code base. In
current (specialized) ufuncs, the elementary function is limited to
element-by-element operations, whereas the generalized version supports
"sub-array" by "sub-array" operations. The Perl vector library PDL provides a
similar functionality and its terms are re-used in the following.

Each generalized ufunc has information associated with it that states what the
"core" dimensionality of the inputs is, as well as the corresponding
dimensionality of the outputs (the element-wise ufuncs have zero core
dimensions). The list of the core dimensions for all arguments is called the
"signature" of a ufunc. For example, the ufunc numpy.add has signature
"(),()->()" defining two scalar inputs and one scalar output.

Another example is (see the GeneralLoopingFunctions page) the function
inner1d(a,b) with a signature of "(i),(i)->()". This applies the inner product
along the last axis of each input, but keeps the remaining indices intact. For
example, where a is of shape (3,5,N) and b is of shape (5,N), this will return
an output of shape (3,5). The underlying elementary function is called 3*5
times. In the signature, we specify one core dimension "(i)" for each input and
zero core dimensions "()" for the output, since it takes two 1-d arrays and
returns a scalar. By using the same name "i", we specify that the two
corresponding dimensions should be of the same size (or one of them is of size
1 and will be broadcasted).

The dimensions beyond the core dimensions are called "loop" dimensions. In the
above example, this corresponds to (3,5).

The usual numpy "broadcasting" rules apply, where the signature determines how
the dimensions of each input/output object are split into core and loop
dimensions:

While an input array has a smaller dimensionality than the corresponding number
of core dimensions, 1's are pre-pended to its shape.  The core dimensions are
removed from all inputs and the remaining dimensions are broadcasted; defining
the loop dimensions.  The output is given by the loop dimensions plus the
output core dimensions.

Experimental Windows 64 bits support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Numpy can now be built on windows 64 bits (amd64 only, not IA64), with both MS
compilers and mingw-w64 compilers:

This is *highly experimental*: DO NOT USE FOR PRODUCTION USE. See INSTALL.txt,
Windows 64 bits section for more information on limitations and how to build it
by yourself.

New features
============

Formatting issues
~~~~~~~~~~~~~~~~~

Float formatting is now handled by numpy instead of the C runtime: this enables
locale independent formatting, more robust fromstring and related methods.
Special values (inf and nan) are also more consistent across platforms (nan vs
IND/NaN, etc...), and more consistent with recent python formatting work (in
2.6 and later).

Nan handling in max/min
~~~~~~~~~~~~~~~~~~~~~~~

The maximum/minimum ufuncs now reliably propagate nans. If one of the
arguments is a nan, then nan is retured. This affects np.min/np.max, amin/amax
and the array methods max/min. New ufuncs fmax and fmin have been added to deal
with non-propagating nans.

Nan handling in sign
~~~~~~~~~~~~~~~~~~~~

The ufunc sign now returns nan for the sign of anan.


New ufuncs
~~~~~~~~~~

#. fmax - same as maximum for integer types and non-nan floats. Returns the
   non-nan argument if one argument is nan and returns nan if both arguments
   are nan.
#. fmin - same as minimum for integer types and non-nan floats. Returns the
   non-nan argument if one argument is nan and returns nan if both arguments
   are nan.
#. deg2rad - converts degrees to radians, same as the radians ufunc.
#. rad2deg - converts radians to degrees, same as the degrees ufunc.
#. log2 - base 2 logarithm.
#. exp2 - base 2 exponential.
#. trunc - truncate floats to nearest integer towards zero.
#. logaddexp - add numbers stored as logarithms and return the logarithm
   of the result.
#. logaddexp2 - add numbers stored as base 2 logarithms and return the base 2
   logarithm of the result result.

Masked arrays
~~~~~~~~~~~~~

Several new features and bug fixes, including:

	* structured arrays should now be fully supported by MaskedArray
	  (r6463, r6324, r6305, r6300, r6294...)
	* Minor bug fixes (r6356, r6352, r6335, r6299, r6298)
	* Improved support for __iter__ (r6326)
	* made baseclass, sharedmask and hardmask accesible to the user (but
	  read-only)
	* doc update

gfortran support on windows
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Gfortran can now be used as a fortran compiler for numpy on windows, even when
the C compiler is Visual Studio (VS 2005 and above; VS 2003 will NOT work).
Gfortran + Visual studio does not work on windows 64 bits (but gcc + gfortran
does). It is unclear whether it will be possible to use gfortran and visual
studio at all on x64.

Arch option for windows binary
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Automatic arch detection can now be bypassed from the command line for the superpack installed:

	numpy-1.3.0-superpack-win32.exe /arch=nosse

will install a numpy which works on any x86, even if the running computer
supports SSE set.

Deprecated features
===================

Histogram
~~~~~~~~~

The semantics of histogram has been modified to fix long-standing issues
with outliers handling. The main changes concern

#. the definition of the bin edges, now including the rightmost edge, and
#. the handling of upper outliers, now ignored rather than tallied in the
   rightmost bin.

The previous behavior is still accessible using `new=False`, but this is
deprecated, and will be removed entirely in 1.4.0.

Documentation changes
=====================

A lot of documentation has been added. Both user guide and references can be
built from sphinx.

New C API
=========

Multiarray API
~~~~~~~~~~~~~~

The following functions have been added to the multiarray C API:

	* PyArray_GetEndianness: to get runtime endianness

Ufunc API
~~~~~~~~~~~~~~

The following functions have been added to the ufunc API:

	* PyUFunc_FromFuncAndDataAndSignature: to declare a more general ufunc
	  (generalized ufunc).


New defines
~~~~~~~~~~~

New public C defines are available for ARCH specific code through numpy/npy_cpu.h:

	* NPY_CPU_X86: x86 arch (32 bits)
        * NPY_CPU_AMD64: amd64 arch (x86_64, NOT Itanium)
        * NPY_CPU_PPC: 32 bits ppc
        * NPY_CPU_PPC64: 64 bits ppc
        * NPY_CPU_SPARC: 32 bits sparc
        * NPY_CPU_SPARC64: 64 bits sparc
        * NPY_CPU_S390: S390
        * NPY_CPU_IA64: ia64
        * NPY_CPU_PARISC: PARISC

New macros for CPU endianness has been added as well (see internal changes
below for details):

	* NPY_BYTE_ORDER: integer
	* NPY_LITTLE_ENDIAN/NPY_BIG_ENDIAN defines

Those provide portable alternatives to glibc endian.h macros for platforms
without it.

Portable NAN, INFINITY, etc...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

npy_math.h now makes available several portable macro to get NAN, INFINITY:

        * NPY_NAN: equivalent to NAN, which is a GNU extension
        * NPY_INFINITY: equivalent to C99 INFINITY
        * NPY_PZERO, NPY_NZERO: positive and negative zero respectively

Corresponding single and extended precision macros are available as well. All
references to NAN, or home-grown computation of NAN on the fly have been
removed for consistency.

Internal changes
================

numpy.core math configuration revamp
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This should make the porting to new platforms easier, and more robust. In
particular, the configuration stage does not need to execute any code on the
target platform, which is a first step toward cross-compilation.

http://projects.scipy.org/numpy/browser/trunk/doc/neps/math_config_clean.txt

umath refactor
~~~~~~~~~~~~~~

A lot of code cleanup for umath/ufunc code (charris).

Improvements to build warnings
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Numpy can now build with -W -Wall without warnings

http://projects.scipy.org/numpy/browser/trunk/doc/neps/warnfix.txt

Separate core math library
~~~~~~~~~~~~~~~~~~~~~~~~~~

The core math functions (sin, cos, etc... for basic C types) have been put into
a separate library; it acts as a compatibility layer, to support most C99 maths
functions (real only for now). The library includes platform-specific fixes for
various maths functions, such as using those versions should be more robust
than using your platform functions directly. The API for existing functions is
exactly the same as the C99 math functions API; the only difference is the npy
prefix (npy_cos vs cos).

The core library will be made available to any extension in 1.4.0.

CPU arch detection
~~~~~~~~~~~~~~~~~~

npy_cpu.h defines numpy specific CPU defines, such as NPY_CPU_X86, etc...
Those are portable across OS and toolchains, and set up when the header is
parsed, so that they can be safely used even in the case of cross-compilation
(the values is not set when numpy is built), or for multi-arch binaries (e.g.
fat binaries on Max OS X).

npy_endian.h defines numpy specific endianness defines, modeled on the glibc
endian.h. NPY_BYTE_ORDER  is equivalent to BYTE_ORDER, and one of
NPY_LITTLE_ENDIAN or NPY_BIG_ENDIAN is defined. As for CPU archs, those are set
when the header is parsed by the compiler, and as such can be used for
cross-compilation and multi-arch binaries.

   # Where "box" is a gtk.Box already part of your layout.
   box.pack_start(scroll)
   pixbuf = gtk.gdk.pixbuf_new_from_file("someimage.png")
   view.set_pixbuf(pixbuf)

Subject: Elisa Media Center 0.5.35 Release
Message-ID: <49DA3A74.6020105@fluendo.com>

Dear Python users,

The Elisa team is happy to announce the release of Elisa Media Center
0.5.35, code-named "The Great Debate".

Elisa is a cross-platform and open-source Media Center written in Python.
It uses GStreamer [1] for media playback and pigment [2] to create an
appealing and intuitive user interface.

New features include the ability to manually re-organize TV shows,
movies and unclassified videos, and consistent font sizes throughout the UI.

This release is a "heavy" release, meaning a windows installer is
available for download on our website and ubuntu packages (for hardy and
intrepid) in our PPA.
Since the latest version of pigment is required for this version to run,
no upgrade via the plugin repository will be available.

As usual, tarballs are provided for distribution packagers.


A complete list of the issues fixed can be found at:

http://bugs.launchpad.net/elisa/+milestone/0.5.35

This is also summarised in the (attached) release notes.

Installers and sources can be downloaded from
http://elisa.fluendo.com/download/

Bug reports and feature requests are welcome at
http://bugs.launchpad.net/elisa/+filebug


Have a media-centered evening,


Olivier, for the Elisa team

Message-ID: <d7a4c05d0904071753te6f4fe8u708e6a4e2330669c@mail.gmail.com>

We are pleased to announce the release of scikits.timeseries 0.91.0

This is the first official public release of the scikits.timeseries module.
Due to the long birthing period, the api is considered stable and the version
number was chosen to reflect the relative maturity of the initial release
compared to a typical first release.

Home page: http://pytseries.sourceforge.net/
Please see the website for installation requirements and download details.
Note that the recently released numpy 1.3.0 is a strict requirement.

Windows binaries are provided for Python 2.5 and 2.6.

About the package
=================

The scikits.timeseries module provides classes and functions for
manipulating, reporting, and plotting time series of various frequencies. The
focus is on convenient data access and manipulation while leveraging the
existing mathematical functionality in numpy and scipy.

If the following scenarios sound familiar to you, then you will likely
find the scikits.timeseries module useful:

   * Compare many time series with different ranges of data (eg. stock
     prices);
   * Create time series plots with intelligently spaced axis labels;
   * Convert a daily time series to monthly by taking the average value
     during each month;
   * Work with data that has missing values;
   * Determine the last business day of the previous month/quarter/year for
     reporting purposes;
   * Compute a moving standard deviation efficiently;

These are just some of the scenarios that are made very simple with the
scikits.timeseries module.

Thanks,
Matt Knox & Pierre Gerard-Marchant

Subject: ANN: SimPy (Simulation in Python) 2.0.1 release
Message-ID: <D69CD3486B314CD5897B2B71FE37730D@VistaMonster>

We are happy to announce the release of SimPy 2.0.1, a bug-fix release of version 2.0.

Download from: 
https://sourceforge.net/project/showfiles.php?group_id=62366&release_id=674197

Your feedback (errors found, proposals for changes, etc.) is requested, using the SimPy Users Mailing List (simpy-users {at}lists.sourceforge.net).

SimPy 2.0.1 requires Python 2.3 or later. It does not yet run under Python 3.
The release of a SimPy version for Python 3 is planned for later in 2009, depending on the development progress of Python 3.

What is SimPy?
------------------------
SimPy is a process-based discrete-event simulation language based on standard Python and released under the GNU LGPL. 

It provides the modeller with components of a simulation model. These include processes, for active components like customers, messages, and vehicles, and

resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics.

Simpy comes with extensive documentation, tutorials and many example models.

SimPy provides plotting and a GUI capability "out of the box".

What is new in SimPy 2.0.1?
-------------------------------------------

Bug fixes
==========

- Repaired a number of coding errors in several
  models in the SimPyModels folder.
  
- Repaired SimulationRT.py bug introduced by recoding for the OO API.

- Repaired errors in sample programs in documents:

  * Simulation with SimPy - In Depth Manual
  * SimPy's Object Oriented API Manual
  * Simulation With Real Time Synchronization Manual
  * SimPlot Manual
  * Publication-quality Plot Production With Matplotlib Manual
  
Additions
============

- Tests for real time behavior (testRT_Behavior.py and
  testRT_Behavior_OO.py in folder SimPy).

Acknowledgements
----------------------------
The development of SimPy 2.0.1 has benefitted tremendously from the excellent, extensive contributions by
Fabrice Benichou. Thanks, Fabrice! You have been a great editor! Keep working with us!

The many other contributions of the SimPy user and developer communities are of course also gratefully acknowledged.

Download, test, enjoy and give us feedback!

Happy SimPying!

Subject: ANN: python-ldap-2.3.7
Message-ID: <49DDF433.1050705@stroeder.com>

Find a new release of python-ldap:

  http://python-ldap.sourceforge.net/

python-ldap provides an object-oriented API to access LDAP directory
servers from Python programs. It mainly wraps the OpenLDAP 2.x libs for
that purpose. Additionally it contains modules for other LDAP-related
stuff (e.g. processing LDIF, LDAPURLs and LDAPv3 schema).

Note that the download page has changed recently. You can now find the
source distribution at PyPI:

  http://pypi.python.org/pypi/python-ldap/

Ciao, Michael.

Need to get up-to-speed with Python as quickly as possible? Come join
me, Wesley Chun, author of Prentice-Hall's bestseller "Core Python
Programming," for a comprehensive intro course coming up this June in
beautiful Northern California! Please pass on this note to whomever
you think may be interested. I look forward to meeting you and your
colleagues!

(Comprehensive) Introduction to Python
Mon-Wed, 2009 Jun 15-17, 9am-5pm

(COMPREHENSIVE) INTRODUCTION TO PYTHON

Although this course may appear to those new to Python, it is also
perfect for those who have tinkered with it and want to "fill in the
gaps" and/or want to get more in-depth formal training. ?It combines
the best of both an introduction to the language as well as a "Python
Internals" training course.

We will immerse you in the world of Python in only a few days, showing
you more than just its syntax (which you don't really need a book to
learn, right?). Knowing more about how Python works under the covers,
including the relationship between data objects and memory management,
will make you a much more effective Python programmer coming out of
the gate. 3 hands-on labs each day will help hammer the concepts home.

Come find out why Google, Yahoo!, Disney, ILM/LucasFilm, VMware, NASA,
Ubuntu, YouTube, Slide, and Red Hat all use Python. Users supporting
or jumping to Plone, Zope, TurboGears, Pylons, Django, Google App
Engine, Jython, IronPython, and Mailman will also benefit!

FREE PREVIEW 1: you will find (and can download) a video clip of a
live lesson that was delivered recently to get an idea of the lecture
style and interactive classroom environment at:

http://cyberwebconsulting.com (click "Python Training")

FREE PREVIEW 2: Partnering with O'Reilly and Pearson, Safari Books
Online has asked me to deliver a 1-hour webcast on Wednesday morning
2009 Apr 29 @ 10:30a PDT/1:30p EDT called "What is
Python?" This will be an online seminar based on a session
that I've delivered at numerous conferences in the past. It will give
you an idea of lecture style as well as an overview of the material
covered in the course. Plus the first 10 registrants will receive an
autographed copy of "Core Python Programming!" For more

where there is a sound programming library to provide tools without
writing them..  It is ment to be completly customisable the data from
the grid itself is saved to a file and then can be used for any
purpose.  It is written in python and the graphics are done with the
pycap game engine and is completly self contained no other downloads
are needed.  (python 2.5 is what is embeded)

Message-ID: <20090410155345.GA18406@panix.com>

Some posts to comp.lang.python.announce are not making it out to Usenet.
We're investigating why, but MIME seems to somehow be involved -- plain
text posts seem to work fine.

We will try to monitor and make sure that all submissions get to Usenet,
but we recommend that people who care check themselves by monitoring both
the newsgroup comp.lang.python.announce and the mailing list
python-list-announce or the p-l-a archive at mail.python.org (so far, all
posts have gotten to the mailing list).

If you don't see your post within a few hours of it showing up on the
list (or a couple of days if you're monitoring with Google Groups ;-),
please send e-mail to python-announce-list-owner at python.org

Subject: [ANN] IronPython in Action available
Message-ID: <f521768b-cd72-4e20-a50c-6474585c7d36@q2g2000vbr.googlegroups.com>

After two and a half years of work IronPython in Action is finally
available!

    http://www.ironpythoninaction.com/

IronPython in Action is the first book (in English anyway...) on
IronPython. It is written by myself and my colleague Christian
Muirhead, with a foreword by Jim Hugunin (the original creator of
IronPython). The technical editor is Dino Viehland, core IronPython
developer.

Two of the chapters are available for free download:

* Chapter 1: A New Lanugage for .NET
* Chapter 7: Agile Testing - Where Dynamic Typing Shines

Links to the free chapters, and IronPython in Action on the Manning
site, Amazon.com and the Safari bookshelf are on the book website.

IronPython is the first of a new wave of dynamic languages for
the .NET framework, built on the Dynamic Language Runtime. IronPython
in Action is aimed at C# / VB.NET programmers interested in dynamic
languages and the possibilities of the DLR, plus Python programmers
wanting to take advantage of the .NET framework.

Subject: Version 2.4 of mod_wsgi is now available.
Message-ID: <dc414c6a-9b89-43bb-8186-1dfbd01aac69@u39g2000pru.googlegroups.com>

Version 2.4 of mod_wsgi is now available. The software and
documentation are both available from:

  http://www.modwsgi.org

The mod_wsgi package consists of an Apache web server module designed
and implemented specifically for hosting Python based web applications
that support the WSGI interface specification.

Examples of major Python web frameworks and applications which are
known to work in conjunction with mod_wsgi include CherryPy, Django,
MoinMoin, Pylons, Trac, TurboGears, Werkzeug and Zope.

Version 2.4 of mod_wsgi is principally a bug fix update. It fixes
memory leaks, configuration corruption, truncation of request/response
data and other minor issues. A small number of other minor
improvements have also been made.

Because of the issue related to truncation of response data, it is
highly recommended that if you are using any prior version of mod_wsgi
2.X with a web application that make use of the wsgi.file_wrapper
extension, such as Trac, that you upgrade.

A description of changes in version 2.4 can be found in the change
notes at:

  http://code.google.com/p/modwsgi/wiki/ChangesInVersion0204

If you have any questions about mod_wsgi or wish to provide feedback,
use the Google group for mod_wsgi found at:

Subject: [ANN] Pyjamas 0.5p1 Web Widget Set and python-to-javascript Compiler 
	released
Message-ID: <ced5f0f60904120950i3e89b264lb4f3d18570b90614@mail.gmail.com>

Pyjamas 0.5p1 - http://pyjs.org - is a bug-fix release.

Pyjamas is a Web Widget Framework, written in python, that is compiled
to javascript using its stand-alone python-to-javascript compiler.  It
began as a port of GWT, to python.

Many of the issues faced by web developers - javascript and CSS
incompatibilities and difficulties - simply go away, with Pyjamas,
thanks to the declarative style used for Pyjamas application
development, that's near-identical to that of python-qt4, python-gtk2
and python-wxWidgets.

The use of Pyjamas for application development turns web browsers into
a desktop widget application development platform, with the added
advantage over traditional desktop widget sets of having full access
to the complete set of HTML features of web browsers.

The stand-alone python-to-javascript compiler is also beginning to
develop into a python accelerator.  The combination of pyjs and pyv8,
or pyjs and python-spidermonkey, offers some interesting possibilities
for JIT compilation of python applications into x86 or ARM assembler
(using pyv8), by way of intermediate compilation to javascript.
Anyone who is interested in the possibilities should contact the
pyjamas developers at http://groups.google.com/group/pyjamas-dev

Message-ID: <a381b1d9-bec3-43ee-9880-eb023867dd0d@o6g2000yql.googlegroups.com>

KeepNote is a simple cross-platform note taking program implemented
in Python.  I have been using it for my research and class notes, but
it
should be applicable to many note taking situations.

KeepNote is ideal for storing your class notes, TODO lists, research
notes, journal entries, paper outlines, etc in a simple notebook
hierarchy with rich-text formatting, images, and more. Using full-text
search, you can retrieve any note for later reference.

KeepNote is designed to be cross-platform (runs on Windows, Linux, and
MacOS X, implemented in Python and PyGTK) and stores your notes in
simple and easy to manipulate file formats (HTML and XML). Archiving
and transferring your notes is as easy as zipping or copying a
folder.  KeepNote is licensed under GPL.

KeepNote 0.5.2 has the following features:

    * Rich-text formatting
      * Bullet point lists
      * Colored font
      * Inline images
      * hyperlinks
    * Hierarchical organization for notes
    * Full-text search
    * Integrated screenshot
    * Extension framework
    * Spell checking (via gtkspell)
    * Auto-saving
    * Built-in backup and restore (archive to zip files)
    * Cross-platform (Linux, Windows, MacOS X)

Hi,

I managed to screw up the date, so here it goes again:

I'd like to announce that there will be a Python Bug Day on April 25.
As always, this is a perfect opportunity to get involved in Python
development, or bring your own issues to attention, discuss them and
(hopefully) resolve them together with the core developers.

We will coordinate over IRC, in #python-dev on irc.freenode.net,
and the Wiki page http://wiki.python.org/moin/PythonBugDay has all
important information and a short list of steps how to get set up.

Please spread the word!

Georg

Subject: relatorio 0.5.1 released
Message-ID: <20090416102010.GA28180@kinder.nutellux.ath.cx>

Hello,

I'm quite happy to announce the new release of relatorio. This release
fixes a nasty bug on tags without attributes and a packaging issue.

Here is the full changelog:

  * Simplified the examples
  * Fix usage of tags without attributes (choose & otherwise)
  * Print original traceback when a module can not be loaded
  * Do not import relatorio in setup.py
  * Better handling of namespaces
  * Added some tests

What is relatorio
-----------------

Relatorio is a templating library which provides a way to easily
output several kinds of files (odt, ods, png, svg, ...). Support for
more filetypes can be easily added by creating plugins for them.

Relatorio also provides a report repository allowing you to link
python objects and report together, find reports by
mimetype/name/python object.

Subject: ANN: ConfigObj 4.6.0 and Validate 1.0.0 released
Message-ID: <a7312226-7e0a-4a1f-8df9-13777515d6fe@k38g2000yqh.googlegroups.com>

Finally a fresh release ConfigObj and Validate.

* ConfigObj Home page: http://www.voidspace.org.uk/python/configobj.html
* Validate Home page: http://www.voidspace.org.uk/python/validate.html

**ConfigObj** is a simple to use but powerful Python library for the
reading and writing of configuration (ini) files. Through **Validate**
it integrates a config file validation and type conversion system.

Features of ConfigObj include:

* Nested sections (subsections), to any level
* List values
* Multiple line values
* Full Unicode support
* String interpolation (substitution)
* Integrated with a powerful validation system

    - including automatic type checking/conversion
    - and allowing default values
    - repeated sections

* All comments in the file are preserved
* The order of keys/sections is preserved
* Powerful ``unrepr`` mode for storing/retrieving Python data-types

Release 4.6.0 fixes bugs and adds new features, particularly making
configspec handling more flexible.

Full details on the changes can be found at:
http://www.voidspace.org.uk/python/weblog/arch_d7_2009_04_11.shtml#e1078

The changelog for ConfigObj 4.6.0 is:

* Pickling of ConfigObj instances now supported (thanks to Christian
Heimes)
* Hashes in confgspecs are now allowed (see note below)
* Replaced use of hasattr (which can swallow exceptions) with getattr
* ``__many__`` in configspecs can refer to scalars (ordinary values)
as well as sections
* You can use ``___many___`` (three underscores!) where you want to
use ``__many__`` as well
* You can now have normal sections inside configspec sections that use
``__many__``
* You can now create an empty ConfigObj with a configspec,
programmatically set values and then validate
* A section that was supplied as a value (or vice-versa) in the actual
config file would cause an exception during validation (the config
file is still broken of course, but it is now handled gracefully)
* Added ``as_list`` method
* Removed the deprecated ``istrue``, ``encode`` and ``decode`` methods
* Running test_configobj.py now also runs the doctests in the
configobj module
* Through the use of validate 1.0.0 ConfigObj can now validate multi-
line values

As the public API for Validate is stable, and there are no outstanding
issues or feature requests, I've bumped the version number to 1.0.0.
The full change log is:

* BUGFIX: can now handle multiline strings
* Addition of 'force_list' validation option

Subject: ANN: Mock 0.5.0 Release
Message-ID: <d6a2e875-683c-4274-aebe-5e15298d0257@c36g2000yqn.googlegroups.com>

Mock 0.5.0 has just been released.

* Mock Homepage http://www.voidspace.org.uk/python/mock/
* Download Mock 0.5.0 release (zip) http://www.voidspace.org.uk/downloads/mock-0.5.0.zip
* Mock Documentation as a PDF http://www.voidspace.org.uk/downloads/mock.pdf
* Mock entry on PyPI http://pypi.python.org/pypi/mock/
* Repository and Issue Tracker on Google Code http://code.google.com/p/mock/

This *isn't* backwards compatible as it cleans up the API in a few
ways, but they're all good changes I promise.

One of the new features is that the Mock class now supports wrapping
objects; using the ``wraps`` keyword.

Mock is a library for the creation of simple mock objects that track
how they are used so that you can make assertions. It uses the action -
> assertion pattern rather than the record -> replay pattern. Action -
> assertion puts your tests after you have used the objects, which
seems more natural and means that you can make assertions about only
the behavior you are interested in. Mock also contains two decorators
(``patch`` and ``patch_object``) which make it easy to safely mock out
dependencies in the module under test purely within the scope of the
test itself (unpatching is done automatically on exit whether or not
the test passes). One of the changes in this release is that these
decorators also become context managers allowing them to be used with
the 'with statement'.

Mock can be installed with:

    ``easy_install mock``

The changelog for all changes in this release is:

* Made DEFAULT part of the public api.
* Documentation built with Sphinx.
* ``side_effect`` is now called with the same arguments as the mock is
called with and
  if returns a non-DEFAULT value that is automatically set as the
``mock.return_value``.
* ``wraps`` keyword argument used for wrapping objects (and passing
calls through to the wrapped object).
* ``Mock.reset`` renamed to ``Mock.reset_mock``, as reset is a common
API name.
* ``patch`` / ``patch_object`` are now context managers and can be
used with ``with``.
* A new 'create' keyword argument to patch and patch_object that
allows them to patch
  (and unpatch) attributes that don't exist. (Potentially unsafe to
use - it can allow
  you to have tests that pass when they are testing an API that
doesn't exist - use at
  your own risk!)
* The methods keyword argument to Mock has been removed and merged
with spec. The spec
  argument can now be a list of methods or an object to take the spec
from.
* Nested patches may now be applied in a different order (created
mocks passed
  in the opposite order). This is actually a bugfix.
* patch and patch_object now take a spec keyword argument. If spec is
  passed in as 'True' then the Mock created will take the object it is
replacing
  as its spec object. If the object being replaced is a class, then
the return
  value for the mock will also use the class as a spec.
* A Mock created without a spec will not attempt to mock any magic
methods / attributes
  (they will raise an ``AttributeError`` instead).

Many thanks to all those who gave feedback, feature requests and
patches!

What *isn't* in 0.5.0 is support for mocking magic methods. I do have
a technique in mind for this, which I implemented for the container
methods. It is very clean, but different from the pattern used to mock
out other methods. As I'm not currently using it I'm going to wait
until I need it and see if it works well in practise.

If you're interested in trying it, the code (with full documentation)
in a 'magics branch':

and there have been no new functional enhancements to pyparsing.  I
take
this as a further sign that pyparsing is reaching a development/
maturity
plateau.

With the help of the pyparsing community, there are some
compatibility
upgrades, and few bug fixes.  The major news is compatibility with
Python 3 and IronPython 2.0.1.  Here is the high-level summary of
what's
new in pyparsing 1.5.2:

- Removed __slots__ declaration on ParseBaseException, for
  compatibility with IronPython 2.0.1.  Raised by David
  Lawler on the pyparsing wiki, thanks David!

- Added pyparsing_py3.py module, so that Python 3 users can use
  pyparsing by changing their pyparsing import statement to:

      import pyparsing_py3

  Thanks for help from Patrick Laban and his friend Geremy
  Condra on the pyparsing wiki.

- Fixed bug in SkipTo/failOn handling - caught by eagle eye
  cpennington on the pyparsing wiki!

- Fixed second bug in SkipTo when using the ignore constructor
  argument, reported by Catherine Devlin, thanks!

- Fixed obscure bug reported by Eike Welk when using a class
  as a ParseAction with an errant __getitem__ method.

- Simplified exception stack traces when reporting parse
  exceptions back to caller of parseString or parseFile - thanks
  to a tip from Peter Otten on comp.lang.python.

- Changed behavior of scanString to avoid infinitely looping on
  expressions that match zero-length strings.  Prompted by a
  question posted by ellisonbg on the wiki.

- Enhanced classes that take a list of expressions (And, Or,
  MatchFirst, and Each) to accept generator expressions also.
  This can be useful when generating lists of alternative
  expressions, as in this case, where the user wanted to match
  any repetitions of '+', '*', '#', or '.', but not mixtures
  of them (that is, match '+++', but not '+-+'):

      codes = "+*#."
      format = MatchFirst(Word(c) for c in codes)

  Based on a problem posed by Denis Spir on the Python tutor
  list.

- Added new example eval_arith.py, which extends the example
  simpleArith.py to actually evaluate the parsed expressions.

========================================
Pyparsing is a pure-Python class library for quickly developing
recursive-descent parsers.  Parser grammars are assembled directly in
the calling Python code, using classes such as Literal, Word,
OneOrMore, Optional, etc., combined with operators '+', '|', and '^'
for And, MatchFirst, and Or.  No separate code-generation or external
files are required.  Pyparsing can be used in many cases in place of
regular expressions, with shorter learning curve and greater
readability and maintainability.  Pyparsing comes with a number of
parsing examples, including:
- "Hello, World!" (English, Korean, Greek, and Spanish(new))
- chemical formulas
- configuration file parser
- web page URL extractor
- 5-function arithmetic expression parser
- subset of CORBA IDL
- chess portable game notation
- simple SQL parser
- Mozilla calendar file parser
- EBNF parser/compiler
- Python value string parser (lists, dicts, tuples, with nesting)
  (safe alternative to eval)
- HTML tag stripper
- S-expression parser
- macro substitution preprocessor

		* * * Last Two Weeks to Register * * *

Just a friendly reminder that there is still time to register for the
two Python training classes I'm offering in Chicago next month.  Come
enjoy the beautiful Chicago spring weather and spend all of your time
indoors getting your Python groove on!

Introduction to Python, May 11-13, 2009
---------------------------------------
A comprehensive tour of the Python programming language and its most
essential library modules. Even if you've already been programming
Python, this class will fill in details, give you new insight, and
teach you practical techniques that you can take home and apply to
your own projects.

Python Concurrency Workshop, May 14-15, 2009
--------------------------------------------
A one-of-a-kind workshop that covers everything you ever wanted to
know about concurrent programming in Python, but were afraid to ask.
Topics include threads, the new multiprocessing library, asynchronous
I/O, coroutines, C extensions, and more.  For good measure, the class
will also touch upon other advanced topics including decorators,
metaclasses, ctypes, and context-managers.  Even if you're not writing
concurrent programs, you'll walk away with new ideas on how to solve
tricky programming problems and see some of Python's newest features
in action.

Further details including registration information is at:

I'm pleased to announce three Python tutorial sessions to be
presented at the 2009 USENIX Technical Conference in San Diego.

The Python Programming Language, June 14, 2009  (All Day)
---------------------------------------------------------
This tutorial provides a comprehensive tour of the Python programming
language and shows how it can be used to solve a variety of practical
problems. The tutorial will illustrate important concepts through
examples that primarily focus on data analysis, systems programming,
and system administration.

Introduction to Python Concurrency, June 15, 2009 (Morning)
-----------------------------------------------------------
A overview of the state of concurrent programming in Python.  Topics
include threads, message passing, multiprocessing, asynchronous I/O,
and coroutines.

Python Generator Hacking, June 15, 2009 (Afternoon)
---------------------------------------------------
Generators and generator expressions are among the most useful
features of Python. Yet many Python programmers are unsure how to
apply them to real-world problems. This tutorial presents practical
uses of generators, including processing large data files, handling
real-time data sequences, parsing, threads, networking, and
distributed computing.

Message-ID: <49ECA167.4070805@fluendo.com>

Dear Python users,

The Elisa team is happy to announce the release of Elisa Media Center
0.5.36, code-named "Surfin' Bird".

Elisa is a cross-platform and open-source Media Center written in Python.
It uses GStreamer [1] for media playback and pigment [2] to create an
appealing and intuitive user interface.

This release is a lightweight release, meaning it is pushed through
our automatic plugin update system. Additionally a windows installer is
available for download on our website. This installer fixes various
crashers.
As usual, for users running a version of Elisa >= 0.5.35, the upgrade to
0.5.36 should be done automatically via the plugin repository.

As usual, tarballs are provided for distribution packagers.

A complete list of the issues fixed can be found at:

http://bugs.launchpad.net/elisa/+milestone/0.5.36

This is also summarised in the (attached) release notes.

Installers and sources can be downloaded from
http://elisa.fluendo.com/download/

Bug reports and feature requests are welcome at
http://bugs.launchpad.net/elisa/+filebug


Have a media-centered evening,


Olivier, for the Elisa team

Subject: itools 0.60.0 released
Message-ID: <49EDE9C5.7010306@itaapy.com>


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 itools.vfs package has been rewritten to use gio, the virtual file
system from the glib project [1].  The web server (itools.web) now uses
the glib event loop.

Extracting text from office formats is in general much faster.  Command
line utilities have been replaced by libraries; for instance,  now we
use 'xlrd' [2] instead of 'xlhtml' [3] to extract text from Excel files.

Indexing text is also much faster now that itools.xapian uses the native
Xapian [4] tokenizer.  Except for Japanese and Chinese, which still use
the itools tokenizer.

The filesystem database, from itools.handlers, has been much improved:

- A read-only mode has been added, implemented by the 'RODatabase'
   class.

- There is a new 'GitDatabase' class that provides atomic transactions
   and versioning (using Git [5]).

- Now there is a limit to the number of file handlers that can be stored
   in the cache (defaults to five thousands).

The code has been re-arranged a little:

- The itools.isetup package has been renamed to itools.pkg, and so have
   been the related scripts: isetup-build.py renamed to ipkg-build.py,
   etc.

- There is a new itools.core package with some basic stuff, the utils.py
   module at the top level has been removed.

- There are three new packages, split from other packages: itools.python
   from itools.handlers, itools.xmlfile from itools.xml and itools.office
   from itools.xml
The implementation of RML [6] has been removed, now we promote PML
instead.

See the README file for details on the updated requirements to install
itools, and the UPGRADE-0.60.0 file for further details on what has
changed.

Subject: ikaaro 0.60.0 released
Message-ID: <49EDED8B.9090308@itaapy.com>


This is a Content Management System built on Python & itools, among
other features ikaaro provides:

  - content and document management (index&search, metadata, etc.)
  - multilingual user interfaces and content
  - high level modules: wiki, forum, tracker, etc.

This version adds versioning of the whole database using Git [1].  The
user interface for the "Last Changes" view is now the database log; and
every commit in the log can be inspected to see what changed.

A profiling framework for both time and space [2] usage has been added.
Profiling is disabled by default, it can be enabled by setting the
'profile-time' and 'profile-space' parameters in the configuration file.
The icms-update.py and icms-update-catalog.py scripts also accept the
'--profile' parameter to produce time profiling information.

The new configuration variable 'database-size' can be used to define the
maximum number of file handlers that will be stored in the cache, and so
limit the space usage.

Now it is possible to index and store multilingual information in the
catalog.  For example, all the translations of the title propery are
now indexed, and so it is possible to search in some specific language
(title_en, title_fr, etc.) or in all languages (title).

Subject: ANN: Python-SIMPL precompiled (i386) binary v1.3.1 released
Message-ID: <a91fc55e-bd02-467d-82fb-e63aa327cfac@x3g2000yqa.googlegroups.com>

The SIMPL open source project (http://www.icanprogram.com/simpl)
produces an ultra lightweight toolkit which is useful for connecting
Python modules to modules written in any number of other languages (C,C
++, Tcl/Tk or JAVA) using the Send/Receive/Reply messaging scheme
first pioneered by QNX.

The Python-SIMPL extension has been available in source form for
several years.   Unfortunately that meant that Python newcomers to the
SIMPL project had to install the full Python sources to get the SIMPL
toolkit to compile.   Only the Python runtime installation is required
to use the (i386) precompiled binary release.    This precompiled
binary release comes in a convenient self installing archive which
allows for an exploratory installation in /tmp with the option for a
full install.

http://www.icanprogram.com/simpl/pythonbin.self.html

While the Python-SIMPL extension has been used on several projects
over the years,  we at the SIMPL project are always on the lookout for
the simplest possible Python-SIMPL demo which has any real world proof
of concept value.   If you have any ideas in that regard or any
suggestions for improvement to the Python-SIMPL interface do not
hesitate contact me directly.

PS.
For more "hello world" level examples of how to use the Python-SIMPL
extension you can consult the online tutorial at:

Hi,

I'd like to remind everyoone that there will be a Python Bug Day on
April 25.  As always, this is a perfect opportunity to get involved
in Python development, or bring your own issues to attention, discuss
them and (hopefully) resolve them together with the core developers.

We will coordinate over IRC, in #python-dev on irc.freenode.net,
and the Wiki page http://wiki.python.org/moin/PythonBugDay has all
important information and a short list of steps how to get set up.

Hope to see you there!

Subject: itools 0.60.1 released
Message-ID: <49F1B82F.7060907@itaapy.com>


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

Now Python 2.6 is required.

New feature in itools.git, there are now facilities to start a process
that will specialize in calling Git commands, and send the data back to
the parent process.  This is useful for applications that may take more
than a little memory, so instead of forking a big process we fork an
small process; this reduces the probability of a MemoryError, and saves
the time to copy large chunks of memory.  (This is a work-around to the
fact that Git is not yet available as a library, but the mechanism could
be useful for anything that uses the 'subprocess' module.)

The itools.handlers package now includes a read-only version of the Git
database, it is named 'ROGitDatabase'.

Some errors fixed, including #640.

Message-ID: <8180ef690904250415t70700e54hd3b82ee6462ebdf2@mail.gmail.com>

Hi all,

I have recently released version 0.1.1 of Shed Skin, an experimental
(restricted-)Python-to-C++ compiler.

This version comes with 5 new example programs (for a total of 35
examples, at over 10,000 lines in total). The most interesting new
example is Minilight (http://www.hxa.name/minilight/), a global
illumination renderer (or raytracer), that uses triangle primitives
and an octree spatial index. According to the Minilight homepage, it
becomes up to 100 times faster. Another interesting new example is
Peter Norvig's sudoku solver (http://norvig.com/sudoku.html), which
unfortunately doesn't become faster but is cool anyway.

Please see my blog for more information about the new release:

http://shed-skin.blogspot.com

The project homepage can be found here:

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

As I don't get much help, please consider joining the project. See my
blog for some ideas on how to help out. More test cases and bug
reports would also be very welcome.


Thanks,
Mark Dufour.

Hi All,

        
  I'm pleased to announce the release of PyEnchant version 1.5.2.
        
  This release fixes compatibility with py2exe, which had been broken
during the move from SWIG to ctypes.  I've also included a unittest to
ensure that such breakage doesn't happen again.

  Thanks to Stephen George for the initial fix on this one. 


  Cheers,


    Ryan


About PyEnchant:
----------------

Enchant (http://www.abisource.com/enchant/) is the spellchecking
package behind the AbiWord word processor, is being considered for
inclusion in the KDE office suite, and is proposed as a
FreeDesktop.org standard. It's completely cross-platform because
it wraps the native spellchecking engine to provide a uniform
interface.

PyEnchant brings this simple, powerful and flexible spellchecking
engine to Python:

  http://pyenchant.sourceforge.net/

It also provides extended functionality including classes for tokenizing
text and iterating over the spelling errors in it, as well as a
ready-to-use text interface and wxPython dialog.


Current Version: 1.5.2
Licence: LGPL with exemptions, as per Enchant itself

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Hello,

I'm pleased to announce pyxser-1.0rc1, a Python-Object to XML
serializer and deserializer. This package it's completly
written in C and licensed under LGPLv3.

The tested Python versions are 2.5.X and 2.7.X.

* home page:
? http://coder.cl/software/pyxser

* hosted at:
? https://sourceforge.net/projects/pyxser/

The current ChangeLog is as follows:

- -----8<----------8<----------8<----------8<-----
1.0rc1 (2009.04.26):

        Daniel Molina Wegener <dmw at coder.cl>
        * Added both byte string and unicode returning and procesing
        functions. This means that we have serialize(),
        serialize_c14n(), serialize_c14n_strict(), unserialize(),
        validate() and validate_c14n() functions for byte strings
        and u_serialize(), u_serialize_c14n(), u_serialize_c14n_strict(),
        u_unserialize(), u_validate() and u_validate_c14n() for
        unicode strings.
        * Removed memory leaks, now it runs over 1400000 pyxser
        operations without crashing (100000 cicles testing every
        function).
        * Removed bugs concerning reference counting that was
        crashing when trying to access unserialized objects attributes.
        * This is an approach to a production environment release ;)
- -----8<----------8<----------8<----------8<-----

Feel free to use and test. You can modify test-utf8-prof.py
to use more than 100.000 cicles without crashing.

Subject: Elisa Media Center 0.5.37 Release
Message-ID: <49F5DC6F.40801@fluendo.com>

Dear Python users,

The Elisa team is happy to announce the release of Elisa Media Center
0.5.37, code-named "Doubledecker".

Elisa is a cross-platform and open-source Media Center written in Python.
It uses GStreamer [1] for media playback and pigment [2] to create an
appealing and intuitive user interface.

This release is a lightweight release, meaning it is pushed through
our automatic plugin update system. Additionally a windows installer is
available for download on our website.
As usual, for users running a version of Elisa >= 0.5.35, the upgrade to
0.5.37 should be done automatically via the plugin repository.

As usual, tarballs are provided for distribution packagers.

A complete list of the issues fixed can be found at:

http://bugs.launchpad.net/elisa/+milestone/0.5.37

This is also summarised in the (attached) release notes.

Installers and sources can be downloaded from
http://elisa.fluendo.com/download/

Bug reports and feature requests are welcome at
http://bugs.launchpad.net/elisa/+filebug


Have a media-centered evening,


Olivier, for the Elisa team

CodeInvestigator version 0.11.1 was released on April 28.


Bug fix:
    - A windows installation issue was resolved.


CodeInvestigator is a tracing tool for Python programs.

Running a program through CodeInvestigator creates a recording.
Program flow, function calls, variable values and conditions are all
stored for every line the program executes.
The recording is then viewed with an interface consisting of the
code. The code can be clicked: A clicked variable displays its
value,
a clicked loop displays its iterations.
You read code, and have at your disposal all the run time details of
that code. A computerized desk check tool and another way to learn
about your program.

Subject: PyPy 1.1 final released!
Message-ID: <49F718E1.1070109@gmx.de>

==========================================
PyPy 1.1: Compatibility & Consolidation
==========================================

Welcome to the PyPy 1.1 release - the first release after the end of EU
funding. This release focuses on making PyPy's Python interpreter more
compatible with CPython (currently CPython 2.5) and on making the
interpreter more stable and bug-free.

PyPy's Getting Started lives at:

    http://codespeak.net/pypy/dist/pypy/doc/getting-started.html

Highlights of This Release
==========================

   - More of CPython's standard library extension modules are supported,
     among them ctypes, sqlite3, csv, and many more. Most of these extension
     modules are fully supported under Windows as well.

     http://codespeak.net/pypy/dist/pypy/doc/cpython_differences.html
     http://morepypy.blogspot.com/2008/06/pypy-improvements.html

   - Through a large number of tweaks, performance has been improved by
     10%-50% since the 1.0 release. The Python interpreter is now between
     0.8-2x (and in some corner case 3-4x) slower than CPython. A large
     part of these speed-ups come from our new generational garbage
     collectors.

     http://codespeak.net/pypy/dist/pypy/doc/garbage_collection.html

   - Our Python interpreter now supports distutils as well as
     easy_install for pure-Python modules.

   - We have tested PyPy with a number of third-party libraries. PyPy can
     run now: Django, Pylons, BitTorrent, Twisted, SymPy, Pyglet, Nevow,
     Pinax:

     http://morepypy.blogspot.com/2008/06/running-nevow-on-top-of-pypy.html

   - A buildbot was set up to run the various tests that PyPy is using
     nightly on Windows and Linux machines:

     http://codespeak.net:8099/

   - Sandboxing support: It is possible to translate the Python
     interpreter in a special way so that the result is fully sandboxed.

     http://codespeak.net/pypy/dist/pypy/doc/sandbox.html
     http://blog.sandbox.lt/en/WSGI%20and%20PyPy%20sandbox


Other Changes
=============

   - The ``clr`` module was greatly improved. This module is used to
     interface with .NET libraries when translating the Python
     interpreter to the CLI.

     http://codespeak.net/pypy/dist/pypy/doc/clr-module.html
     http://morepypy.blogspot.com/2008/01/pypynet-goes-windows-forms.html
     http://morepypy.blogspot.com/2008/01/improve-net-integration.html

   - Stackless improvements: PyPy's ``stackless`` module is now more
     complete. We added channel preferences which change details of the
     scheduling semantics. In addition, the pickling of tasklets has been
     improved to work in more cases.

   - Classic classes are enabled by default now. In addition, they have
     been greatly optimized and debugged:


http://morepypy.blogspot.com/2007/12/faster-implementation-of-classic.html

   - PyPy's Python interpreter can be translated to Java bytecode now to
     produce a pypy-jvm. At the moment there is no integration with
     Java libraries yet, so this is not really useful.

   - We added cross-compilation machinery to our translation toolchain to
     make it possible to cross-compile our Python interpreter to Nokia's
     Maemo platform:

     http://codespeak.net/pypy/dist/pypy/doc/maemo.html

   - Some effort was spent to make the Python interpreter more
     memory-efficient. This includes the implementation of a mark-compact
     GC which uses less memory than other GCs during collection.
     Additionally there were various optimizations that make Python
     objects smaller, e.g. class instances are often only 50% of the size
     of CPython.


http://morepypy.blogspot.com/2008/10/dsseldorf-sprint-report-days-1-3.html

   - The support for the trace hook in the Python interpreter was
     improved to be able to trace the execution of builtin functions and
     methods. With this, we implemented the ``_lsprof`` module, which is
     the core of the ``cProfile`` module.

   - A number of rarely used features of PyPy were removed since the 
previous
     release because they were unmaintained and/or buggy. Those are: The
     LLVM and the JS backends, the aspect-oriented programming features,
     the logic object space, the extension compiler and the first
     incarnation of the JIT generator. The new JIT generator is in active
     development, but not included in the release.

     http://morepypy.blogspot.com/2009/03/jit-bit-of-look-inside.html


What is PyPy?
=============

Technically, PyPy is both a Python interpreter implementation and an
advanced compiler, or more precisely a framework for implementing 
dynamic languages and generating virtual machines for them.

The framework allows for alternative frontends and for alternative
backends, currently C, Java and .NET.  For our main target "C", we can
"mix in" different garbage collectors and threading models,
including micro-threads aka "Stackless".  The inherent complexity that
arises from this ambitious approach is mostly kept away from the Python
interpreter implementation, our main frontend.

Socially, PyPy is a collaborative effort of many individuals working
together in a distributed and sprint-driven way since 2003.  PyPy would
not have gotten as far as it has without the coding, feedback and
general support from numerous people.

Subject: Jython 2.5 Beta 4 Released
Message-ID: <4dab5f760904281232w643605b9pbef185db4cd488e2@mail.gmail.com>

Jython 2.5b4 is available for download here:
http://downloads.sourceforge.net/jython/jython_installer-2.5b4.jar.
See the installation instructions here:
http://www.jython.org/Project/installation.html.

While no new features have been added since Beta 3, we have fixed a
number of bugs. One of the bugs prompted an almost total re-write of
our Tuple and List implementations, which is the reason that this is
another beta and not a release candidate. Expect a release candidate
real soon now.

We also applied a patch that allows Jython to function in a system
that does not have write access to the filesystem so that Jython can
run unpatched in Google App Engine.  See here for more:
http://groups.google.com/group/google-appengine-java/web/will-it-play-in-app-engine.

This is a beta release so be careful.

-Frank

Subject: bzr 1.13.2 released!
Message-ID: <BF991B4E-C4FE-458B-A87B-97DFD7F334AC@real-time.com>

A regression was found in the 1.13.1 release. When bzr 1.13.1 and  
earlier push a stacked branch they do not take care to push all the  
parent inventories for the transferred revisions. This means that a  
smart server serving that branch often cannot calculate inventory  
deltas for the branch (because smart server does not/cannot open  
fallback repositories). Prior to 1.13 the server did not have a verb  
to stream revisions out of a repository, so that's why this bug has  
appeared now.

The Bazaar team is happy to announce availability of a new release of  
the bzr adaptive version control system.

Thanks to everyone who contributed patches, suggestions, and feedback.

Bazaar is now available for download from http://bazaar-vcs.org/ 
Download as a source tarball; packages for various systems will be  
available soon.

Subject: [ANN] BPT (Boxed Package Tool)
Message-ID: <5F5603A9-B094-4B2C-BD8D-34FB711D0B41@gmail.com>

Hi all,
I am pleased to announce BPT 0.2a (despite the number, this is the  
first public version).

http://pypi.python.org/pypi/bpt

Like virtualenv, BPT allows to create isolate environments, but it is  
not limited to Python software, as it can be used to install arbitrary  
Unix software. It can be used for development (several versions of the  
same software can be installed in the same environment, and  
administrator privileges are not needed), and for deployment of  
complete installations (the environments are relocatable).

Feel free to use and test it, comments are welcome.

What is BPT
===========

BPT is a Python library (``bpt``) and a command line application
(``box``) to create and manage isolated enviroments, or *boxes*. Boxes
are *relocatable*, which means that they can be moved to a different
directory or even distributed to other machines (provided that the
architecture is compatible). Packages inside the box can be easily
disabled, enabled and removed, so that different versions of the same
software can be installed simultaneously, allowing to switch between
them.

BPT is similar in some ways to `virtualenv
<http://pypi.python.org/pypi/virtualenv>`_, but it is not restricted
to Python packages, allowing to install virtually any Unix
software. It also takes some ideas from `jhbuild
<http://live.gnome.org/Jhbuild>`_, but without the dependency
resolution and automatic downloading machinery, and the ``bpt-rules``
format is inspired by `Gentoo <http://www.gentoo.org/>`_'s ebuilds.

Message-ID: <49F995BD.80007@pythonlibrary.org>

Hi,

Our May Pyowa meeting is next Monday, May 4th. It will be held at the 
Marshall County Sheriff's Office from 7-9 p.m. Direction are on the 
website: www.pyowa.org.

Agenda (in  no particular order):

1) Introduction to SqlAlchemy - An object oriented way of connecting to 
a database with a "pythonic" API.
2) Nick Fox from Fox Media Systems in Des Moines will talk about his 
experiences with Python and (maybe) his experience as a core developer 
for the Mythbuntu project.
3) A short GIS Code review - We'll look at some auto-generated ArcGIS(?) 
code from one of our members and try to improve it.

If you need a laptop to follow along, we have some that can be made 
available as long as you let me know ahead of time. I've been told that 
we will have snacks this time as well as pop and water.

Also note that the Iowa Code Camp is this Saturday. The reason I mention 
this is that there's a Django talk there and there may be a 
Python-related "open space" type thing too. You can check out the 
schedule here: http://iowacodecamp.com/. Iowa Code Camp is in Cedar 
Rapids. Go and support Python!

Anyway, I hope to see you next Monday! Let me know if you have any 
questions.

Blurb:

GObject is a object system library used by GTK+ and GStreamer.

PyGObject provides a convenient wrapper for the GObject library for use
in Python programs, and takes care of many of the boring details such as
managing memory and type casting.  When combined with PyGTK, PyORBit and
gnome-python, it can be used to write full featured Gnome applications.

Like the GObject library itself PyGObject is licensed under the
GNU LGPL, so is suitable for use in both free software and proprietary
applications.  It is already in use in many applications ranging
from small single purpose scripts up to large full
featured applications.

PyGObject requires glib >= 2.14.0 and Python >= 2.3.5 to build.
GIO bindings require glib >= 2.16.0.
