Pyzor 0.5 Released
by Tony Meyer 07 May '09

07 May '09

The Pyzor team is pleased to announce release 0.5 of Pyzor. The previous release was made in September of 2002, so it has obviously been a while! With this release, we have aimed to resolve all the outstanding reported bugs and incorporate submitted patches (many of which are also from some time ago). The hope is that this, along with the recent improvements to the public Pyzor server, revitalises the Pyzor project. We are aiming to release the next version of Pyzor, which will include new features, around the end of June (2009!). If you'd like to have input into that release, please subscribe to the pyzor-users mailing list, or monitor the SourceForge tickets for the Pyzor project. We are very keen to have as much input from the user-base as possible. The majority of the improvements in the 0.5 release were submitted from the Debian Pyzor package. Many thanks to them for pushing these back 'upstream' - if you have any improvements that you are running locally, please consider doing the same and contributing these as patches to the main Pyzor package (open a ticket on the SourceForge site). Main changes include: * Man pages for pyzor and pyzord. * Changing back to signals for database locking, rather than threads. It is likely that signals will be removed again in the future, but the existing threading changes caused problems. * Basic checks on the results of "discover". * Extended mbox support throughout the library. * Better handling on unknown encodings. * Added a --log option to log to a file. * Better handling of command-line options. * Improved error handling. You can get the release (via the 'download' link on the left), as well as information about the mailing lists and other news, at: http://pyzor.org Enjoy the new release and your reduced spam mail :) As always, thanks to everyone involved in this release! Tony. (on behalf of the Pyzor team) --- What is Pyzor? --- Pyzor is a collaborative, networked system to detect and block spam using identifying digests of messages. Pyzor initially started out to be merely a Python implementation of Razor, but due to the protocol and the fact that Razor's server is not Open Source or software libre, Frank Tobin decided to implement Pyzor with a new protocol and release the entire system as Open Source and software libre. Since the entire system is released under the GPL, people are free to host their own independent servers, although there is a well-maintained public server available (public.pyzor.org), which anyone is welcome to use.

[RELEASED] Python 3.1 beta 1
by Benjamin Peterson 07 May '09

07 May '09

On behalf of the Python development team, I'm thrilled to announce the first and only beta 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. File system APIs that use unicode strings now handle paths with undecodable bytes in them. [1] 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 a beta release, 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 beta 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 For more information and downloadable distributions, see the Python 3.1 website: http://www.python.org/download/releases/3.1/ See PEP 375 for release schedule details: http://www.python.org/dev/peps/pep-0375/ Enjoy, -- Benjamin Benjamin Peterson benjamin at python.org Release Manager (on behalf of the entire python-dev team and 3.1's contributors)

06 May '09

Hello! I'm pleased to announce version 0.10.5, a minor bugfix release of 0.10 branch of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.10.5 News and changes: http://sqlobject.org/News.html What's New ========== News since 0.10.4 ----------------- * Another unicode-related patch for MySQL; required because different versions of MySQLdb require different handling:: - MySQLdb < 1.2.1: only ascii - MySQLdb = 1.2.1: only unicode - MySQLdb > 1.2.1: both ascii and unicode * Setup requires FormEncode version 1.1.1+. * Fixed a minor bug - pass name to DecimalValidator. * Fixed a bug in InheritableIteration - pass connection to child klass.select(). * sqlmeta.getColumns() becomes classmethod. * A bug was fixed in PostgresConnection.columnsFromSchema() - foreign keys are now recognized and created as proper ForeignKey with correct column name and table name. * Bugs in PostgresConnection and MSSQLConnection related to properties was fixed. A note for developers: from now on properties in DBConnection classes are forbidden as they don't work with Transaction - Transaction.__getattr__() cannot properly wrap 'self' so a property is called with wrong 'self'. * Transaction instances now explicitly raises TypeError on close() - without this calling Transaction.close() calls connection.close() which is wrong. * A bug in SQLiteConnection.columnsFromSchema() that led to an infinite loop was fixed. For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

Python Training in Chicago - Last day to register
by David Beazley 04 May '09

04 May '09

Python Training In Downtown Chicago May 11-15, 2009 http://www.dabeaz.com/chicago * * * Last Day 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: http://www.dabeaz.com/chicago Cheers, Dave -- David Beazley (http://www.dabeaz.com) Author "Python Essential Reference"

IMDbPY 4.1 and IMDbPYKit 1.1.1
by Davide Alberani 04 May '09

04 May '09

IMDbPY 4.1 and IMDbPYKit 1.1.1 are 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. IMDbPYKit (mostly developed by H. Turgut Uyar) is a web interface to IMDbPY, able to serve its output both in HTML and XML. With this release, a DTD for the XML output was formalized and support for i18n was introduced. A lot of bugs were fixed. Platform-independent and written in pure Python (and few C lines), IMDbPY 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> [GPG KeyID: 0x465BFD47] http://erlug.linux.it/~da/
