Hi all,
I am pleased to announce that `guidata` v1.5.0 has been released (http://guidata.googlecode.com).
Based on the Qt Python binding module PyQt4 (and mostly compatible with PySide), guidata is a Python library generating graphical user interfaces for easy dataset editing and display. It also provides helpers and application development tools for PyQt4.
guidata also provides the following features:
* guidata.qthelpers: PyQt4 helpers
* guidata.disthelpers: cx_Freeze/py2exe helpers (or how to build a self-consistent executable in three lines of code!)
* guidata.userconfig: .ini configuration management helpers (based on Python standard module ConfigParser)
* guidata.configtools: library/application data management
* guidata.gettext_helpers: translation helpers (based on the GNU tool gettext)
* guidata.guitest: automatic GUI-based test launcher
* guidata.utils: miscelleneous utilities
guidata has been successfully tested on GNU/Linux and Windows platforms.
This is mostly a maintenance release with a couple of bugfixes and minor new features (see changelog here: http://code.google.com/p/guidata/wiki/ChangeLog).
The Mercurial repository is now publicly available here:
http://code.google.com/p/guidata/source/checkout
The `guidata` documentation with examples, API reference, etc. is available here:

Just wanted to send out this quick reminder--today is the last day for
PyTexas $25 registration; starting tomorrow it will cost $50.
http://www.pytexas.org/chance/1/register/
Today is also your last day to post your talk proposals.
http://www.pytexas.org/chance/1/talks/add/
Btw, there is going to be a PyTexas t-shirt given away with every
registration. I've seen advance drafts which are beautiful, drawn and
colored by Kat Metgzer, the same artist who did the PyTexas 2010
t-shirt. This evening after work I might be able to post the artwork
on the PyTexas blog.
PipeController is a tool that I wrote to experiment with simulating simple, sequential, synchronous UNIX-style pipes in Python. It is the first release - v0.1.
Blog post about PipeController:
http://jugad2.blogspot.in/2012/08/pipecontroller-v01-released-simulating.ht…
The blog post gives some information about the design of PipeController and an example of how to use it.
Download PipeController:

gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the
CPython interpreter within GCC, allowing you to write new compiler
warnings for C/C++ in Python, generate code visualizations, etc. It
comes with "cpychecker": a tool for static analysis tool of CPython
extensions.
Tarball releases are available at:
https://fedorahosted.org/releases/g/c/gcc-python-plugin/
Prebuilt-documentation can be seen at:
http://readthedocs.org/docs/gcc-python-plugin/en/latest/index.html
Project homepage:
https://fedorahosted.org/gcc-python-plugin/
What's new in v0.10:
* support for the to-be-released Python 3.3 (tested against latest
release candidate)
* better support for analysis of C++ code: the API provides support
for walking the namespace tree, and the cpychecker code now supports
methods, references, "this", destructors, etc
* lots of bug fixes: the cpychecker code has been hardened by running
it on all of the Python C extension code in Fedora 17, and in the
process many internal bugs have been found and fixed - along with
hundreds of bugs in the code being tested:
http://fedoraproject.org/wiki/Features/StaticAnalysisOfPythonRefcounts
* similarly, Daniele Varrazzo used the checker extensively on psycopg,
the popular Python interface to PostgreSQL, and using it was able to
find and fix numerous subtle errors:
http://initd.org/psycopg/articles/2012/03/29/psycopg-245-released/
* an experimental new HTML visualization for error reports:
http://fedorapeople.org/~dmalcolm/gcc-python-plugin/2012-03-19/example/exam…
Thanks to Buck Golemon, Daniele Varrazzo, David Narvaez, Eevee, Jason
Mueller, Kevin Pyle, Matt Rice and Tom Tromey for their contributions to
this release.
Enjoy!
Dave
I'm happy to announce the release of six 1.2.0. Six is a Python 2 and
3 compatibility library. It provides utility functions for smoothing
over the differences between the Python versions with the goal of
writing Python code that is compatible on both Python 2.x and 3.x. It
supports Python 2.4-3.3.
Six can be downloaded on PyPI:
http://pypi.python.org/pypi/six
See the code and report bugs on BitBucket:
http://bitbucket.org/gutworth/six
The complete changelog in this release is:
- Issue #13: Make iterkeys/itervalues/iteritems return iterators on Python 3
instead of iterables.
- Issue #11: Fix maxsize support on Jython.
- Add six.next() as an alias for six.advance_iterator().
- Use the builtin next() function for advance_iterator() where is available
(2.6+), not just Python 3.
- Add the Iterator class for writing portable iterators.
Enjoy,
Benjamin

________________________________________________________________________
NEWS
The 3.2.0 release of our mxODBC is a new release of our popular Python
ODBC Interface for Windows, Linux, Mac OS X and FreeBSD.
New Features in 3.2
-------------------
* Switched to unixODBC 2.3.1+ API: mxODBC is now compiled against
unixODBC 2.3.1, which finally removes the problems with the ABI
change between 2.2 and 2.3 by switching to a new library version
(libodbc.so.2).
* mxODBC connection objects can now be used as context managers to
implicitly commit/rollback transactions.
* mxODBC cursor objects can now be used as context managers to
implicitly close the cursor when leaving the block (regardless of
whether an exception was raised or not)
* mxODBC added support for adjustable .paramstyles. Both 'qmark'
(default) and 'named' styles are supported and can be set on
connections and cursors. The 'named' style allows easier porting of
e.g. Oracle native interface code to mxODBC.
* mxODBC now supports a writable connection.autocommit attribute to
easily turn on/off the connection's auto commit mode.
* mxODBC added support for adjustable TIMESTAMP precision via the new
connection/cursor.timestampresolution attribute.
* mxODBC will round to nearest nanosecond fraction instead of
truncating the value. This will result in fewer conversion errors
due to floating point second values.
* mxODBC's connect APIs Connect() and DriverConnect() support setting
connection options prior to connecting to the database via a new
connection_options parameter. This allows enabling e.g. the MARS
feature in SQL Server Native Client.
* The connection.cursor() constructor now has a new cursor_options
parameters which allows configuring the cursor with a set of cursor
options.
* The .scroll() method supports far more ODBC drivers than before.
* Updated the SQL lookup object to include more ODBC SQL parameter
codes, including special ones for SQL Server and IBM DB2.
* mx.ODBC.Manager will now prefer unixODBC over iODBC. Previous
mxODBC releases used the order iODBC, unixODBC, DataDirect when
looking for a suitable ODBC manager on Unix platforms. unixODBC is
more widely supported nowadays and provides better Unicode support
than iODBC.
For the full set of features mxODBC has to offer, please see:
http://www.egenix.com/products/python/mxODBC/#Features
Driver Compatibility Enhancements
---------------------------------
* Added work-around for Oracle Instance Client to prevent use of
direct execution. cursor.executedirect() will still work, but won't
actually use direct execution with the Oracle driver.
* Added work-around for Oracle Instant Client to prevent segfaults in
the driver when querying the cursor.rowcount or cursor.rownumber.
* Added check to make sure that Python type binding mode is not used
with Oracle Instance Client as this can cause segfaults with the
driver and generally doesn't work.
* Added a work-around to have the IBM DB2 driver return correct
.rowcount values.
* Improved Sybase ASE driver compatibility: this only supports Python
type binding, which is now enabled per default.
* Added work-around for PostgreSQL driver, which doesn't support
scrollable cursors.
* Add support for MS SQL Server ODBC Driver 1.0 for Linux to mxODBC
* Improved compatibility of the mxODBC native Unicode string format
handling with Unix ODBC drivers when running UCS4 builds of Python.
* mxODBC 3.2 now always uses direct execution with the FreeTDS ODBC
driver. This results in better compatibility with SQL Server and
faster execution across the board.
* Add work-around to have FreeTDS work with 64-bit integers outside
the 32-bit signed integer range.
* FreeTDS' .rowcount attribute gave misleading values for
SELECTs. This now always returns -1 (until they hopefully fix the
driver to return usable data).
For the full set of changes please check the mxODBC change log:
http://www.egenix.com/products/python/mxODBC/changelog.html
mxODBC Editions
---------------
mxODBC is available in these three editions:
* The low-cost Standard Edition which provides data connectivity to a
single database type, e.g. just MS SQL Server.
* The Professional Edition, which gives full access to all mxODBC
features.
* The Product Development Edition, which allows including mxODBC in
applications you develop.
Compared to mxODBC 3.0, we have simplified our license terms to
clarify the situation on multi-core and virtual machines. In most
cases, you no longer need to purchase more than one license per
processor or virtual machine, scaling down the overall license costs
significantly compared to earlier mxODBC releases.
For a complete overview of the new editions, please see the product page.
