by Tiziano Zito Oct. 24, 2011

Oct. 24, 2011

We are glad to announce release 3.2 of the Modular toolkit for Data Processing (MDP). 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. Resources --------- Download: http://sourceforge.net/projects/mdp-toolkit/files Homepage: http://mdp-toolkit.sourceforge.net Mailing list: http://lists.sourceforge.net/mailman/listinfo/mdp-toolkit-users Acknowledgments --------------- We thank the contributors to this release: Michael Schmuker, Ben Willmore.

About WSME ---------- WSME (Web Service Made Easy) is a very easy way to implement webservices in your python web application (or standalone). Changes ------- * Changed the internal API by introducing a CallContext object. It makes it easier to implement some protocols that have a transaction or call id that has to be returned. It will also make it possible to implement batch-calls in a later version. * More test coverage. * Various fixes (see also http://packages.python.org/WSME/changes.html) Documentation ------------- http://packages.python.org/WSME/ Download -------- http://pypi.python.org/pypi/WSME/ http://pypi.python.org/pypi/WSME-Soap/ http://pypi.python.org/pypi/WSME-ExtDirect/ Cheers, Christophe de Vienne

ceODBC 2.0.1
by Anthony Tuininga Oct. 15, 2011

Oct. 15, 2011

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? http://ceodbc.sourceforge.net What's new? 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 security leaks. 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.

cx_Oracle 5.1.1
by Anthony Tuininga Oct. 11, 2011

Oct. 11, 2011

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 exceptions. Where do I get it? http://cx-oracle.sourceforge.net What's new? 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 11.2.0.2 and UTF8 character set. 4) Avoid attempting to clear temporary LOBs a second time when destroying the variable as in certain situations this results in spurious errors. 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.

ANN: Pyro 4.10 released
by Irmen de Jong Oct. 11, 2011

Oct. 11, 2011

Hello, Pyro 4.10 has just been released! Get it from Pypi: http://pypi.python.org/pypi/Pyro4/ Documentation: http://packages.python.org/Pyro4/index.html Changes include: * 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. Enjoy, Irmen de Jong
