Press Release SOURCE: Python Software Foundation PYCON 2007 - FIFTH ANNUAL PYTHON COMMUNITY CONFERENCE ADDISON, TX, November 30, 2006 - PyCon 2007, the fifth annual conference of the Python community, will take place February 23-25 at the Dallas/Addison Marriott Quorum hotel. The keynote speakers will include Ivan Krstić, from the One Laptop Per Child project; Adele Goldberg, a developer of Smalltalk; Robert M. Lefkowitz, an expert on the use of open source in business; and Guido van Rossum, the creator of Python. PyCon annually attracts hundreds of attendees interested in the open-source Python language, ranging from novice programmers to developers of the language core. This year's conference will include a record sixty-four sessions, covering the use of Python in a broad range of contexts, such as web development, testing, and cross-language integration; case studies in industry, science, and education; and Python implementations for the Java and .NET platforms. The program will also include intensive half-day tutorials, impromptu Open Space talks, Birds-of-a-Feather topical gatherings, and the ever-popular five-minute Lightning Talks. One new feature this year will be the Python Lab, a collaborative, hands-on problem-solving environment. Following the conference, many developers will stay for Sprints, extending the Python language and Python projects through several days of intense, cooperative coding. PyCon is organized by members of the Python community, and made possible by the Python Software Foundation and conference sponsors. For more information or to register, please visit the PyCon 2007 website: http://us.pycon.org/TX2007/ Information for members of the press is collected at http://us.pycon.org/TX2007/ForPress -- - Catherine http://catherinedevlin.blogspot.com/

Copyright, Michael P. Soulier, 2006. About Release 0.3: ================== This release fixes a major RFC 1350 compliance problem with the remote TID. About Release 0.2: ================== This release adds variable block sizes, and general option support, implementing RFCs 2347 and 2348. This is accessible in the TftpClient class via the options dict, or in the sample client via the --blocksize option. About Release 0.1: ================== This is an initial release in the spirit of "release early, release often". Currently the sample client works, supporting RFC 1350. The server is not yet implemented, and RFC 2347 and 2348 support (variable block sizes) is underway, planned for 0.2. About Tftpy: ============ Tftpy is a TFTP library for the Python programming language. It includes client and server classes, with sample implementations. Hooks are included for easy inclusion in a UI for populating progress indicators. It supports RFCs 1350, 2347 and 2348. This library was developed against Python 2.4.1.

ANN: bridge 0.2.0
by Sylvain Hellegouarch Dec. 8, 2006

Dec. 8, 2006

Hi all, I am pleased to announce the release of bridge 0.2.0, a general purpose XML library for Python and IronPython (and ultimately Jython). bridge is very simple and light. It basically let you load an XML document via a set of different parsers (xml.dom, Amara, lxml, System.Xml and ElementTree) and creates a tree of Elements and Attributes before releasing the parser resources. This means that once the document is loaded it is independent from the underlying parser. bridge then provides a straightforward interface to navigate through the tree and manipulate it. bridge does not try to replace underlying XML engines but offer a common API so that your applications are less dependent of those engines. bridge offers a couple of other goodies however to play with the tree of elements (see the documentation). == What's new? == This release is an important milestone for bridge: * it now supports ElementTree * it fixes major issues with namespace handling and should now work correctly * it adds a set of unit tests * it adds support for Comment and ProcessingInstruction == TODO == Potentially the IronPython implementation is not as up-to-date as the other parsers. This will be quickly fixed. All parsers will generate the same bridge structure. The only minor difference at the present time is coming from the lxml parser which does not preserve processing instructions and comments before the root element. bridge cannot therefore access them. Mind you ElementTree does not preserve either but I was able to workaround this behavior. Add more unit tests. == Download == * easy_install -U bridge * Tarballs http://www.defuze.org/oss/bridge/ * svn co https://svn.defuze.org/oss/bridge/ == Documentation == Wiki: http://trac.defuze.org/wiki/bridge (not yet updated for 0.2.0) API: http://www.defuze.org/oss/bridge/doc/html/ To see the implementation of the parsers you'll need to look at the private API. Have fun, -- Sylvain Hellegouarch http://www.defuze.org

A Call to Arms for Python Advocacy
by Jeff Rush Dec. 7, 2006

Dec. 7, 2006

As the Python Advocacy Coordinator, I've put up some wiki pages on the Python website for which I'm soliciting ideas, writing and graphics. Some of the material exists scattered about and just needs locating and organizing. http://wiki.python.org/moin/Advocacy First there is a need for whitepapers and flyers - I've put up a list of suggested topics w/notes at: http://wiki.python.org/moin/AdvocacyWritingTasks And there are fields for signing up for specific documents. We also have a page of possible magazine articles if that's more your style: http://wiki.python.org/moin/ArticleIdeas. These works are to be formed into advocacy kits for various audiences. So far we have the following ideas for kits: - College Student's Python Advocacy Kit - IT Department Python Advocacy Kit - University Educator's Python Advocacy Kit - K-12 Educator's Python Advocacy Kit - Research Lab Python Advocacy Kit The table of contents for the various kits can be found at: http://wiki.python.org/moin/Advocacy#AdvocacyKits Did we miss your kit? And what would you include in any of these? Next, we are seeking reusable/retargetable teaching materials, such as those under a Creative Commons license. We need slide presentations and class handouts. Now I know there are a great many slide presentations on the web about Python. I can google them all but we're not looking for just any presentation, we're looking for the best of field. You can find the collection point at: http://wiki.python.org/moin/Advocacy#TeachingMaterials Last, perhaps you can dash off an idea or two for promotional merchandise. This could be the usuals like shirts but also posters, bumper stickers and buttons. What would you like to have? And with what graphics or slogans? We can reuse some of the slogans from the PyCon Slogan Contest, but are there others? Our collection point for promo item ideas is at: http://wiki.python.org/moin/Advocacy/WearablesGadgets All materials will be credited to the authors to the extent possible by the delivery media. Make your mark. Jeff Rush <advocate(a)python.org> Python Advocacy Coordinator

ANN: Albow - A simple widget library for Pygame
by greg Dec. 6, 2006

Dec. 6, 2006

ALBOW - A Little Bit of Widgetry for PyGame ------------------------------------------- Version 1.0 This is a very basic, no-frills widget set for creating a GUI using PyGame. It was originally developed for my PyWeek 3 competition entry, Sneak. I am documenting and releasing it as a separate package so that others may benefit from it, and so that it will be permissible for use in future PyGame entries. The download includes HTML documentation and an example program demonstrating most of the library's features. http://www.cosc.canterbury.ac.nz/greg.ewing/python/Albow/ -- Gregory Ewing greg.ewing(a)canterbury.ac.nz
