SpamBayes 1.0a6 Source Release
by Tony Meyer 19 Sep '03

19 Sep '03

Version 1.0a6 of the SpamBayes source is now available. Note: this is not a release of the binary installer for the Outlook plug-in. A separate release for the plug-in installer will follow at a later date. This release follows (reasonably) close on the heals of 1.0a5 and is primarily a reshuffling and tidy-up. All the scripts have been renamed, and all the cruft supporting old option names has been removed. This will almost certainly mean that you have to edit the way you use SpamBayes (to change the name, at least). There are a few other minor improvements and bug fixes. We recommend that all source code users upgrade to the 1.0a6 release, but do so at a time when they have a few minutes available to change over references to script names, and to check their configuration files are using the correct names. Note that the plan is for this to be the final alpha release in the 1.0 series, and that 1.0 is effectively feature frozen from this point. We will continue to fix any bugs that are reported, and should be able to release a very stable 1.0b1 and then final 1.0 release in the near future. Work will soon begin on the 1.1 series, which will (no doubt!) feature many improvements. For full details about what's new in this release, please see the release notes and/or changelog: <http://sourceforge.net/project/shownotes.php?release_id=185545> Downloads are available from <http://spambayes.org/download.html>. =Tony Meyer, on behalf of the spambayes team.

Literate programming in Python
by feng_xia＠instron.com 19 Sep '03

19 Sep '03

Hello, All, I have finally come up a literate programming tool for the Python lovers! :) Yes yes yes! After painful searching over the internet, I came across the Py2tex app which does a nice job of typesetting the Python code. But it's not literate programming yet. Well, to make this short, the one I have is very preliminary. I am not an advanced user in either the Python world or the Latex world. With my very limited knowledge of both, I tried. I don't know how to make the code available to the public. Anyway, please send me an email if you are interested in. And please don't laugh at some of my "crude" techniques programming the beatiful Python. I'm sure there could be a better solution to many of my headaches :) Best regards, feng

Python Database Objects (PDO)
by Bryan J Gudorf 16 Sep '03

16 Sep '03

We at NeuroKode Labs, LLC, are proud to announce the release of Python Database Objects (PDO). Python Database Objects (PDO) provides an easy to use Object Oriented API for database developers. PDO utilizes DB-API modules for database access, but allows for a Common Object Oriented API across RDBMS. Thus, PDO can be thought of as a 'wrapper' around the DB-API and database specific modules. Here is a quick example of the usage of Python Database Objects (PDO): import pdo DBConn =pdo.connect('Module=MySQLdb;User=SalesReader;Passwd=secretpassword;DB=Sales ') Results = DBConn.openRS("SELECT * FROM Customers") while Results.next() print "Name: " + Results['Name'].value Downloads for Python Database Objects are available on SourceForge.Net or for more information please visit pdo.neurokode.com. ~Bryan J Gudorf NeuroKode Labs, LLC

ANN: PythonCard 0.7.2
by Kevin Altis 16 Sep '03

16 Sep '03

PythonCard is a GUI construction kit for building cross-platform desktop applications on Windows, Mac OS X, and Linux. Release 0.7.2 includes over 40 sample applications and tools to help users build applications in Python, including codeEditor, findfiles, and resourceEditor (layout editor). A list of changes since release 0.7 is at the end of this message. All the information you need about PythonCard can be found on the project web page at: http://pythoncard.sourceforge.net/ The installation instructions and walkthroughs are available on the main documentation page: http://pythoncard.sourceforge.net/documentation.html You can download the latest release at: http://sourceforge.net/project/showfiles.php?group_id=19015 For a list of most of the samples that have been built with PythonCard and screenshots of them in action go to: http://pythoncard.sourceforge.net/samples/samples.html The kind people at SourceForge host the project: http://sourceforge.net/projects/pythoncard/ If you want to get involved the main contact point is the Mailing list: http://lists.sourceforge.net/lists/listinfo/pythoncard-users PythonCard requires Python 2.2.1 or later and wxPython 2.4.1.2 or later. wxPython can be downloaded at http://www.wxpython.org/ Additional Notes: Remember to backup or just delete your old PythonCardPrototype directory before installing a new version, so that the old files aren't still in the package directory. If you installed a previous version of PythonCard on Windows using the binary installer, then you should be able to remove the old package via the Add/Remove Programs Control Panel. The distutils installer will put the framework, components, docs, samples, and tools in Lib\site-packages or your Python directory (typically C:\Python22 or C:\Python23). Of course, on Linux and Mac OS X that path will be slightly different and have forward slashes. Windows users should get a PythonCard menu in the Start->Programs menu with links to the documentation, samples, codeEditor, findfiles, and resourceEditor. The tools and most of the samples will now keep their config and data file info in the "pythoncard_config" directory created by the framework. On Unix, the directory will be ~/pythoncard_config. On Windows, the directory varies as described in the following post: http://aspn.activestate.com/ASPN/Mail/Message/PythonCard/1496793 So, if you run a PythonCard app with any of the runtime tools and select "Save Configuration" from the "Debug" menu, the window positions and sizes of your runtime windows (Shell, Message Watcher, etc.) will be saved in "pythoncard_config/pythoncard_config.txt" not the PythonCardPrototype directory. Likewise, when you change the text style used by the codeEditor via the "Styles..." menu item under the "Format" menu, the modification will be saved in "pythoncard_config/stc-styles.rc.cfg" ka --- Kevin Altis altis(a)semi-retired.com http://altis.pycs.net/ --- changelog since release 0.7 Release 0.7.2 2003-09-08 ranamed MultiColumnList 'border' attribute to 'rules' enabled MultiColumnList and Tree in the resourceEditor added minimalList and minimalTree samples as tests of the MultiColumList and Tree components added multicolumnexample by William Volkman replaced older MultiColumnList component with version by William Volkman added workaround for wxMSW GetFont() bug in MultiColumnList switched to Raise() in fixComponentOrder to deal with wxPython 2.4.x change with Hide/Show added shell.autoCompleteWxMethods = False to pycrustrc.py to hide CamelCase wxPython methods of components and other wxPython classes by default added source.encode('iso-8859-1') to textToHtml to avoid print/print preview exceptions in codeEditor; this will probably require a more sophisticated solution added workaround for wxWindows AppendText bug in jabberChat sample.

ANN: XMLFilter 1.1 - read and write XML with or without expat
by awshearer＠shearersoftware.com 15 Sep '03

15 Sep '03

I just released version 1.1 of XMLFilter, which marks the first public standalone release. XMLFilter is an open-source Python module you can include with your programs to provide XML parsing even if the target system lacks a working xml.sax package. For example, you can use it to quickly adapt existing xml.sax-compatible scripts to work out of the box on Jaguar (Mac OS X 10.2), which lacks expat. http://www.shearersoftware.com/software/developers/xmlfilter/ It works by using the older xmllib module as a fallback for xml.sax. A test suite verifies call-by-call compatibility no matter which module ends up being used. Other features include XML event-stream filtering, writing, and creation, with support for writing CDATA sections. (Using these classes also avoids bugs in some versions of xml.sax.) Generally, the newer your version of Python, the faster it goes. For example, if xml.sax and expat are working, they give a factor-of-3 speedup over the pure-Python xmllib, and on Python 2.3, Unicode encoding conversions will use xmlcharrefreplace for faster writing of XML numeric entities. Python-licensed. Tested all the way down to Python 1.5.2 and up to Python 2.3. xml.sax-compatible, Unicode-savvy (wherever Python is), and optionally namespace-aware. <P><A HREF="http://www.shearersoftware.com/software/developers/xmlfilter/">XMLFilter 1.0</a> - Read, filter, and write XML with full compatibility for systems lacking expat.

Today, Phil Knight's Nike is a fading empire, badly hurt by years of "brand damage" as activists and culture jammers fought back against mindfuck marketing and dirty sweatshop labor. Now a final challenge. We take on Phil at his own game - and win. We turn the shoes we wear into a counterbranding game. The swoosh versus the anti-swoosh. Which side are you on? Adbusters has been doing R&D for more than a year, and guess what? Making a shoe - a good shoe - isn't exactly rocket science. With a network of supporters, we're getting ready to launch the blackSpot sneaker, the world's first grassroots anti-brand. You can help launch the blackSpot revolution.

strptime() backported to Jython 2.1
by Brett C. 15 Sep '03

15 Sep '03

I have received a few requests since the 'Python Cookbook' was published to edit my code for a strptime() function in pure Python to run on Jython 2.1 . I have finally come about and made the necessary changes and put them online (thanks to Jon Franz for giving the final push). The code can be found at the Python Cookbook web site at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/56036 . It is not the fastest or best version of the code (that will always be in the Python CVS MAIN tree), but it seems to work (I have not done extensive testingm but all the changes were minor). I now consider this backport finished. All future enhancements to strptime will continue to go into the Python CVS but will not be backported. If you want the latest and greatest features then consider helping to move Jython forward to its next version or upgrading your version of CPython. -Brett
