We are glad to announce release 3.2 of the Modular toolkit for Data
MDP is a Python library of widely used data processing algorithms
that can be combined according to a pipeline analogy to build more
complex data processing software. The base of available algorithms
includes signal processing methods (Principal Component Analysis,
Independent Component Analysis, Slow Feature Analysis),
manifold learning methods ([Hessian] Locally Linear Embedding),
several classifiers, probabilistic methods (Factor Analysis, RBM),
data pre-processing methods, and many others.
What's new in version 3.2?
- improved sklearn wrappers
- update sklearn, shogun, and pp wrappers to new versions
- do not leave temporary files around after testing
- refactoring and cleaning up of HTML exporting features
- improve export of signature and doc-string to public methods
- fixed and updated FastICANode to closely resemble the original
Matlab version (thanks to Ben Willmore)
- support for new numpy version
- new NeuralGasNode (thanks to Michael Schmuker)
- several bug fixes and improvements
We recommend all users to upgrade.

The MDP developers,
py.test 2.1.3: just some fixes
pytest-2.1.3 is a minor backward compatible maintenance release of the
popular py.test testing tool. It is commonly used for unit, functional-
and integration testing. See extensive docs with examples here:
The release contains a fix to the perfected assertions introduced
with the 2.1 series as well as the new possibility to customize the
detailed reporting for assertion expressions on a per-directory level.
If you want to install or upgrade pytest, just type one of::
pip install -U pytest # or
easy_install -U pytest
Thanks to the bug reporters and to Ronny Pfannschmidt, Benjamin Peterson
and Floris Bruynooghe who implemented the fixes.
Changes between 2.1.2 and 2.1.3
- fix issue79: assertion rewriting failed on some comparisons in boolops,
- correctly handle zero length arguments (a la pytest '')
- fix issue67 / junitxml now contains correct test durations
- fix issue75 / skipping test failure on jython
- fix issue77 / Allow assertrepr_compare hook to apply to a subset of tests

What is ceODBC?
ceODBC is a Python extension module that enables access to databases using the
ODBC API and conforms to the Python database API 2.0 specifications with a few
additions. I have tested this on Windows against SQL Server, Access, dBASE
and Oracle and others have reported success on more obscure drivers.
On Linux I have tested this against PostgreSQL and MySQL.
Where do I get it?
1) Removed memory leak that occurred when binding parameters to a
cursor; thanks to Robert Ritchie and Don Reid for discovering this.
2) Remove the password from the DSN in order to eliminate potential
3) Improve performance when logging is disabled or not at level DEBUG
by avoiding the entire attempt to log bind variable values.
4) Use the size value rather than the length value when defining
result set variables since the length value is for the length of the
column name; thanks to Heran Quan for the patch.
5) Added support for Python 3.2.
What is cx_Oracle?
cx_Oracle is a Python extension module that allows access to Oracle and
conforms to the Python database API 2.0 specifications with a few
Where do I get it?
1) Simplify management of threads for callbacks performed by database
change notification and eliminate a crash that occurred under high
load in certain situations. Thanks to Calvin S. for noting the issue
and suggesting a solution and testing the patch.
2) Force server detach on close so that the connection is completely
closed and not just the session as before.
3) Force use of OCI_UTF16ID for NCLOBs as using the default character
set would result in ORA-03127 with Oracle 18.104.22.168 and UTF8 character
4) Avoid attempting to clear temporary LOBs a second time when
destroying the variable as in certain situations this results in
5) Added additional parameter service_name to makedsn() which can be
used to use the service_name rather than the SID in the DSN string
that is generated.
6) Fix cursor description in test suite to take into account the
number of bytes per character.
7) Added tests for NCLOBS to the test suite.
8) Removed redundant code in setup.py for calculating the library path.
Pyro 4.10 has just been released!
Get it from Pypi: http://pypi.python.org/pypi/Pyro4/
* added Flame (foreign location automatic module exposer)
* Pyrolite also gained support for Flame
* added Future class that provides async (future) function calls for any callable (not
just Pyro proxies)
* added parameter to config.refresh to make it ignore environment variables
(See the change log in the documentation for a more detailed list)
This release doesn't yet contain any IPV6 patches. If you want to help test that,
there's a version available in the 'ipv6' branch in subversion. Hopefully those patches
will make it into the next release.
Pyro = Python Remote Objects. It is a library that enables you to build applications in
which objects can talk to each other over the network, with minimal programming effort.
You can just use normal Python method calls, with almost every possible parameter and
return value type, and Pyro takes care of locating the right object on the right
computer to execute the method. It is designed to be very easy to use, and to generally
stay out of your way. But it also provides a set of powerful features that enables you
to build distributed applications rapidly and effortlessly. Pyro is written in 100% pure
Python and therefore runs on many platforms and Python versions, including Python 3.x.

The first version of Rockfish has been released. Rocfish v0.9.0 Beta.
You can get the tarball at URL:
What is Rockfish?
Rockfish provides a gui frontend for command line search programs such
as find and
locate. It is written in Python and currently uses GTK+ (via PyGTK) for
For more details see: http://www.justjohnnyweb.net/~roan/?q=rockfish
* Support for multiple backend search engines/applications
(currently supports find and locate)
* Drag and Drop support -- copy files found by Rockfish to another location
* Configurable via the command line or default user configuration file
('.rockfish.yaml' in the user's home directory).
Rockfish development takes advantage of Launchpad.net. If you'd like to
