by Davide Alberani 06 Jan '09

06 Jan '09

IMDbPY 3.9 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. With this release, improved search for series episodes, support for dumping data in CSV files. Many bugs fixed and other minor improvements. New versions of some IMDbPY-based programs were released, too. Platform-independent and written in pure Python (and few C lines), it can retrieve data from both the IMDb's web server and a local copy of the whole database. IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package; other IMDbPY-based programs are available from the home page. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

PyMC 2.0
by Chris Fonnesbeck 06 Jan '09

06 Jan '09

Hello everyone, It gives me great pleasure to be able to announce the long-awaited release of PyMC 2.0. Platform-specific installers have been uploaded to the Google Code page (Mac OSX) and the Python Package Index (all other platforms), along with the new user's guide (http:// pymc.googlecode.com/files/UserGuide2.0.pdf). PyMC is a python module that implements Bayesian statistical models and ﬁtting algorithms, including Markov chain Monte Carlo (MCMC). Its ﬂexibility makes it applicable to a large suite of problems as well as easily extensible. Along with core sampling functionality, PyMC includes methods for summarizing output, plotting, goodness-of-ﬁt and convergence diagnostics. PyMC 2.0 is a quantum leap from the 1.3 release. It includes a completely revised object model and syntax, more efficient log- probability computation, a variety of specialised MCMC algorithms, and an expanded set of optimised probability distributions. As a result, models built for previous versions of PyMC will not run under version 2.0. I would like to particularly thank Anand Patil and David Huard, who have done most of the work on this version, and to all the users who have sent questions, comments and bug reports over the past year or two. Please keep the feedback coming! Please report any problems with the release to the issues page (http:// code.google.com/p/pymc/issues/list). Python Package Index: http://pypi.python.org/pypi/pymc/ Google Code: http://pymc.googelcode.com Mailing List: http://groups.google.com/group/pymc Happy new year, Chris Fonnesbeck

[Announce] PyGobject 2.16.0 (stable)
by Gian Mario Tagliaretti 05 Jan '09

05 Jan '09

I am pleased to announce version 2.16.0 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://download.gnome.org/sources/pygobject/2.16/ What's new since PyGObject 2.15.4? - gobject.timeout_add_seconds() not found in docs (Paul Pogonyshev, #547119) - _wrap_g_output_stream_write_async not adding a reference to the buffer passed (Paul, #564102) - gio.VolumeMonitor segfaults (Gian Mario Tagliaretti, #555613) - Test if `domain' is not-null before using it to avoids segfaults (Paul, #561826) - g_output_stream_write_all use gsize instead of gssize (Gian) - add __repr__ to gio.Drive, gio.Mount and gio.Volume (Paul, #530935) - Missing AC_CONFIG_MACRO_DIR([m4]) (Loïc Minier, #551227) - Make codegen not import when corresponding argument types are not registered (Paul, #551056) - Fix typos breaking compilation (Frederic Peters #551212) - GFile load_contents methods chop data at first \0 (Jonathan Matthew, #551059) 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. cheers -- Gian Mario Tagliaretti GNOME Foundation member gianmt(a)gnome.org

Release of PyGreSQL 4.0 (update)
by D'Arcy J.M. Cain 02 Jan '09

02 Jan '09

Update: The Windows binaries are now available on the web site. We are please to announce the release of PyGreSQL 4.0. his is a major release and you should check it carefully before using in existing applications. There may be some incompatibilities. PyGreSQL is a Python module that interfaces to a PostgreSQL database. It embeds the PostgreSQL query library to allow easy use of the powerful PostgreSQL features from a Python script. For more information, please visit http://www.PyGreSQL.org/. >From the changelog: - Dropped support for Python below 2.3 and PostgreSQL below 7.4. - Improved performance of fetchall() for large result sets by speeding up the type casts (as suggested by Peter Schuller). - Exposed exceptions as attributes of the connection object. - Exposed connection as attribute of the cursor object. - Cursors now support the iteration protocol. - Added new method to get parameter settings. - Added customizable row_factory as suggested by Simon Pamies. - Separated between mandatory and additional type objects. - Added keyword args to insert, update and delete methods. - Added exception handling for direct copy. - Release the GIL while making a connection (as suggested by Peter Schuller). - If available, use decimal.Decimal for numeric types. - Allow DB wrapper to be used with DB-API 2 connections (as suggested by Chris Hilton). - Made private attributes of DB wrapper accessible. - Dropped dependence on mx.DateTime module. - Support for PQescapeStringConn() and PQescapeByteaConn(); these are now also used by the internal _quote() functions. - Added 'int8' to INTEGER types. New SMALLINT type. - Added a way to find the number of rows affected by a query() with the classic pg module by returning it as a string. For single inserts, query() still returns the oid as an integer. The pgdb module already provides the "rowcount" cursor attribute for the same purpose. - Improved getnotify() by calling PQconsumeInput() instead of submitting an empty command. - Removed compatibility code for old OID munging style. - The insert() and update() methods now use the "returning" clause if possible to get all changed values, and they also check in advance whether a subsequent select is possible, so that ongoing transactions won't break if there is no select privilege. - Added "protocol_version" and "server_version" attributes. - Revived the "user" attribute. - The pg module now works correctly with composite primary keys; these are represented as frozensets. - Removed the undocumented and actually unnecessary "view" parameter from the get() method. - get() raises a nicer ProgrammingError instead of a KeyError if no primary key was found. - delete() now also works based on the primary key if no oid available and returns whether the row existed or not. -- D'Arcy J.M.
