Organizing Python Representation at OSCON 2007
by Jeff Rush 27 Jun '07

27 Jun '07

OSCON 2007 in Portland, Oregon from July 23-27 is fast approaching. This is a professional conference that can give Python a lot of visibility in the IT world and draws a different crowd from our community-run conferences like PyCon. There looks to be a good set of talks on the Python track, with several positioned to promote the use of Python by telling its story: - Code Like a Pythonista: Idiomatic Python - SQLAlchemy: Taming ORM with Python - Super-sizing YouTube - How to Write a Killer Sugar Activity - Exploiting Multicore Capabilities from Python - Python 3000 - Programming for Everybody: CP4E - Coding with Dynamic Confidence There also is the opportunity to reach out by holding Python birds-of-a-feather gatherings. The Python community is a friendly group and face-to-face contact is important to convey the human aspect of Python. BoFs can be scheduled by visiting the OSCON page: http://conferences.oreillynet.com/pub/w/58/bof.html I will not be attending this year, so we need one or more who are willing to step forward and loosely organize a bit. Let's discuss this on the Python advocacy mailing list and make it happen this year. http://mail.python.org/mailman/listinfo/advocacy Jeff Rush Python Advocacy Coordinator

SpamBayes 1.1a4
by skip＠pobox.com 25 Jun '07

25 Jun '07

SpamBayes 1.1a4 (the fourth alpha release) is out. You can download it from SourceForge: <http://spambayes.sourceforge.net/>. This is currently a source only release. There is as yet no Outlook installer. What's New in 1.1a4? ==================== Version 1.1a4 introduces a new application, core_server.py. This application is tailored to provide spam filtering by non-mail applications such as Trac, Roundup, MoinMoin or your favorite blogging server. The external interface is XML-RPC. It also implements a plugin architecture so new protocol adapters can be added easily. What is SpamBayes? ================== The SpamBayes project is working on developing a statistical (commonly, although a little inaccurately, referred to as Bayesian) anti-spam filter, initially based on the work of Paul Graham. The major difference between this and other, similar projects is the emphasis on testing newer approaches to scoring messages. While most anti-spam projects are still working with the original graham algorithm, we found that a number of alternate methods yielded a more useful response. SpamBayes is not a single application. The core code is a message classifier, however there are several applications available as part of the SpamBayes project which use the classifier in specific contexts. For the most part, the current crop of applications all operate on the client side of things, however, a number of people have experimented with using SpamBayes on mail servers to classify incoming mail for multiple users. Contact, Help & Feedback ======================== Please take the new alpha release out for a spin around the block. Report any feedback or problems you have with the new functionality to spambayes-dev(a)python.org. To get general help with SpamBayes, send your questions to spambayes(a)python.org. -- Skip Montanaro - skip(a)pobox.com - http://www.webfast.com/~skip/

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.i18n itools.vfs itools.cms itools.ical itools.web itools.csv itools.pdf itools.workflow itools.datatypes itools.rss itools.xhtml itools.gettext itools.schemas itools.xliff itools.handlers itools.stl itools.xml itools.html itools.tmx itools.http itools.uri A new maintenance script for itools.cms instances has been added, now with icms-update-catalog it is possible to update the catalog from the command line. There is also an small addition to the itools.cms API, the new class variable "class_layout" will allow in most cases to avoid the definition of the method "_get_handler". There have been bug fixes and other small improvements to other packages: itools.handlers, itools.csv, itools.pdf (RML) and itools.cms The French translation has been updated. Credits: - Hervé Cauwelier fixed bugs here and there; - Nicolas Deram fixed bugs and worked on the itools.cms calendar; - J.

lxml 1.3 released
by Stefan Behnel 24 Jun '07

24 Jun '07

Hi all, I'm proud to announce the release of lxml 1.3. http://codespeak.net/lxml/ http://cheeseshop.python.org/pypi/lxml/ ** What is lxml? """ In short: lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language. lxml is a Pythonic binding for the libxml2 and libxslt libraries. It is unique in that it combines the speed and feature completeness of these libraries with the simplicity of a native Python API. """ ** This is a major new release with various new features and lots of fixes compared to the 1.2 series. The complete changelog follows below. Major objectives of this release were: - API consolidation: make everything work with everything - improved namespace handling: avoid redundant namespaces wherever possible - simplicity and accessibility: improved, restructured documentation and simpler XML/HTML generation Future versions of lxml will continue this trend to make lxml the leading tool for XML and HTML in the Python world. Have fun, Stefan Behnel 1.3 (2007-06-24) ================ Features added -------------- * Module ``lxml.pyclasslookup`` implemens an Element class lookup scheme that can access the entire tree to determine a suitable Element class * Parsers take a ``remove_comments`` keyword argument that skips over comments * ``parse()`` function in ``objectify``, corresponding to ``XML()`` etc. * ``Element.addnext(el)`` and ``Element.addprevious(el)`` methods to support adding processing instructions and comments around the root node * Extended type annotation in objectify: cleaner annotation namespace setup plus new ``deannotate()`` function * Support for custom Element class instantiation in lxml.sax: passing a ``makeelement()`` function to the ElementTreeContentHandler will reuse the lookup context of that function * '.' represents empty ObjectPath (identity) Bugs fixed ---------- * Removing Elements from a tree could make them loose their namespace declarations * ``ElementInclude`` didn't honour base URL of original document * Replacing the children slice of an Element would cut off the tails of the original children * ``Element.getiterator(tag)`` did not accept ``Comment`` and ``ProcessingInstruction`` as tags * API functions now check incoming strings for XML conformity. Zero bytes or low ASCII characters are no longer accepted. * XSLT parsing failed to pass resolver context on to imported documents * More ET compatible behaviour when writing out XML declarations or not * ``Element.attrib`` was missing ``clear()`` and ``pop()`` methods * More robust error handling in ``iterparse()`` * Documents lost their top-level PIs and comments on serialisation * lxml.sax failed on comments and PIs. Comments are now properly ignored and PIs are copied. * Raise AssertionError when passing strings containing '\0' bytes 1.3beta (2007-02-27) ==================== Features added -------------- * ``DTD`` validator class (like ``RelaxNG`` and ``XMLSchema``) * HTML generator helpers by Fredrik Lundh in ``lxml.htmlbuilder`` * ``ElementMaker`` XML generator by Fredrik Lundh in ``lxml.builder.E`` * Support for pickeling ``objectify.ObjectifiedElement`` objects to XML * ``update()`` method on Element.attrib * Optimised replacement for libxml2's _xmlReconsiliateNs(). This allows lxml a better handling of namespaces when moving elements between documents. Bugs fixed ---------- * Possible memory leaks in namespace handling when moving elements between documents Other changes ------------- * major restructuring in the documentation
