Zope 3.3.0 beta 1 released!
by Stephan Richter May 8, 2006

May 8, 2006

The Zope 3 development team is proud to announce Zope 3.3.0 beta 1. Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. Cleanup of the Zope 3 packages has continued to ensure a flexible and scalable platform. We continued the work on making the transition from Zope 2 to Zope 3 by making Zope 2.10 use even more of the Zope 3 packages. But we're not there yet. **You can't run Zope 2 applications in Zope 3.** Downloads http://zope.org/Products/Zope3 Installation instructions for both Windows and Un*x/Linux are now available in the top level "README.txt":http://www.zope.org/Products/Zope3/3.3.0b1/README.txt file of the distribution. The binary installer is recommended for Windows. Zope 3.3 requires Python 2.4.1 to run. You must also have zlib installed on your system. Most Important Changes Since 3.2 - Provided a new component registry API that allows multiple component registries to be combined more flexibly than before. See 'zope.component.interfaces.IComponentRegistry' for more information. - Greatly simplified local-component registration. See 'zope.component.interfaces.IComponentRegistry' for more information. - Moved many packages out of zope.app to make them easier to use outside of Zope. - Change the session credentials plugin to make it configurable in which fields it looks for the credentials. - Added a new API for collating text. You can now adapt a locale to 'zope.i18n.interfaces.ILocales.ICollator'. You can then use that to sort strings, such as menu entries, in a locale-specific fashion. - A new 'zope.annotation.factory' helper function that makes it easier to create annotations. Also added a README in 'zope.annotation' which explains how to use it. - Added a more complete set of widgets for fields that use iterable sources. These widgets now mirror the set provided by vocabulary-based fields. - Added a cleaner and more robust API to testbrowser for setting file-upload data. - Deprecated several ZCML directives: * factory * vocabulary * content (as an alias to the class directive) * modulealias * renderer:renderer - The 'browser:layer' directive and the 'ILayer' interface has been deprecated. Registering layers has become obsolete, layers should be created as interfaces extending 'IBrowserRequest'. - The 'browser:skin' directive has been deprecated. Skins should be created as interfaces extending 'IBrowserRequest' and can be registered using a simple 'utility' directive. - The 'ISkin' interface has been renamed to 'IBrowserSkinType'. For a complete list of changes see the 'CHANGES.txt' file. Resources - "Zope 3 Development Web Site":http://dev.zope.org/Zope3 - "Zope 3 Dev Mailing List":http://mail.zope.org/mailman/listinfo/zope3-dev - "Zope 3 Users Mailing List":http://mail.zope.org/mailman/listinfo/zope3-users - IRC Channel: #zope3-dev at irc.freenode.net Acknowledgments Thanks goes to everyone that contributed. Enjoy! The Zope 3 Development Team

ANN: iTorrent alpha-2
by Michael Hobbs May 8, 2006

May 8, 2006

Announcing the second alpha release of iTorrent. iTorrent allows you to download BitTorrent podcasts from iTunes. It transforms BitTorrent podcasts so that you can update them just like any other podcast in iTunes. Details can be found at http://www.itorrent.cc. iTorrent is written in Python and is released under the GPL. With its second alpha release, iTorrent still isn't pretty, but it is much easier to install and run. Technical Details: iTorrent runs as an RSS proxy on your local machine and will fetch enclosures from a BitTorrent network on behalf of iTunes. The BitTorrent content will then be fed to iTunes via a standard HTTP loopback connection. It uses the official BitTorrent 4.4.0 code to perform the actual downloads from a BitTorrent network. (http://www.bittorrent.com) Regards, - Michael Hobbs <mike(a)hobbshouse.org>

ANN: progressbar 2.2 - Text mode progressbar for console applications
by Nilton Volpato May 7, 2006

May 7, 2006

Text progressbar library for python. http://cheeseshop.python.org/pypi/progressbar This library provides a text mode progressbar. This is tipically used to display the progress of a long running operation, providing a visual clue that processing is underway. The ProgressBar class manages the progress, and the format of the line is given by a number of widgets. A widget is an object that may display diferently depending on the state of the progress. There are three types of widget: - a string, which always shows itself; - a ProgressBarWidget, which may return a diferent value every time it's update method is called; and - a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it expands to fill the remaining width of the line. The progressbar module is very easy to use, yet very powerful. And automatically supports features like auto-resizing when the terminal size is changed. It's also efficient, because the text is only updated if need, with a minimum overhead in the case there is no need for updating. It was tested and works under windows, linux and macosx. And should also work in many other untested operating systems. You may get it from pypi: http://cheeseshop.python.org/pypi/progressbar Thanks, Nilton. -- Nilton Volpato email: "%s.%s(a)gmail.com" % ('nilton', 'volpato')
