[ANN] notmm is not a monolithic mashup 0.2.10 released !
by Etienne Robillard 27 Sep '08

27 Sep '08

Hi, I'm delighted to announce the release of notmm 0.2.10, aka "botryococcus braunii", the world first and only heterogeneous web toolkit with a algae-based nickname ! *:-) notmm is a open, non-monolithic, and Python written web toolkit, mostly influenced by Django and Pylons development. Imho, its simple design makes it a clever and remarquable choice from a security perspective, and in particular for building extendable mashups/web APIs. Homepage: http://gthc.org/projects/notmm/ Discussion group: http://groups.google.com/group/notmm-discuss/ Mercurial repository: http://joelia.gthc.org/projects/notmm/0.2.10-maint/ On the PyPi archive: http://pypi.python.org/pypi/notmm/0.2.10/ This is a stable release and as usual, updating is recommended. Its also a important mile stone for notmm development; and I sincerely enjoyed programming the whole thing, since the previous and now obsolete 0.2.9 release. Too many things has changed since the "phycocyanine" release. Most importantly, support for Elixir, SQLAlchemy and WSGI has been greatly improved. Making it mostly compatible with Django 1.0 was also an important feature, however I'd be interested in comments regarding this. Does it work for you without patching Django ? Moreover, for thoses interested in patching Django, I recommend you to check out django.bugfixes, a sister-project for notmm-0.2.10: $ hg clone http://joelia.gthc.org/django.bugfixes/ django.bugfixes This repository is clonable with Mercurial, and offers a series of patches for patching Django. So please read the README for more info.. :0) Best regards, Etienne -- Etienne Robillard Software Developer, Green Tea Hackers Club Website: http://gthc.org/ Email: robillard.etienne (at) gmail.com

TakeNote 0.4.2 - Note taking and organization In this release: * faster loading * bullet point lists * more customization * bug fixes TakeNote is a simple cross-platform note taking program implemented in Python. I have been using it for my research and class notes, but it should be applicable to many note taking situations. Although this is my first release, it has most of the basic features needed for effective notes. TakeNote is ideal for storing your class notes, TODO lists, research notes, journal entries, paper outlines, etc in a simple notebook hierarchy with rich-text formatting, images, and more. Using full-text search, you can retrieve any note for later reference. TakeNote is designed to be cross-platform (runs on Windows, Linux, and MacOS X, implemented in Python and PyGTK) and stores your notes in simple and easy to manipulate file formats (HTML and XML). Archiving and transferring your notes is as easy as zipping or copying a folder. TakeNote is licensed under GPL. TakeNote 0.4.2 is has the following features: * Rich-text formatting * Bullet point lists * Hierarchical organization for notes * Full-text search * Inline images * Integrated screenshot * Spell checking (via gtkspell) * Auto-saving * Built-in backup and restore (archive to zip files) * Cross-platform (Linux, Windows, MacOS X) Web site and download: http://rasm.ods.org/takenote Matt Rasmussen

ANN: NumPy 1.2.0
by Jarrod Millman 26 Sep '08

26 Sep '08

I'm pleased to announce the release of NumPy 1.2.0. NumPy is the fundamental package needed for scientific computing with Python. It contains: * a powerful N-dimensional array object * sophisticated (broadcasting) functions * basic linear algebra functions * basic Fourier transforms * sophisticated random number capabilities * tools for integrating Fortran code. Besides it's obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide-variety of databases. This minor release comes almost four months after the 1.1.0 release. The major features of this release are a new testing framework and huge amount of documentation work. It also includes a some minor API breakage scheduled in the 1.1 release. Please note that NumPy 1.2.0 requires Python 2.4 or greater. For information, please see the release notes: http://sourceforge.net/project/shownotes.php?group_id=1369&release_id=628858 You can download the release from here: http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103 Thank you to everybody who contributed to this release.

Nagare web framework - 0.1.0
by Alain Poirier 24 Sep '08

24 Sep '08

Hi all, I'm pleased to announce that the first (0.1.0) version of the Nagare web framework is released! To read about its features: http://www.nagare.org/trac/wiki/NagareFeatures Release info and download page: http://pypi.python.org/pypi/nagare/ Source and documentation are available at the website: http://www.nagare.org Mailing lists: http://groups.google.com/group/nagare-users About Nagare ============ Nagare is a components based framework: a Nagare application is a composition of interacting components each one with its own state and workflow kept on the server. Each component can have one or several views that are composed to generate the final web page. This enables the developers to reuse or write highly reusable components easily and quickly. Thanks to Stackless Python, Nagare is also a continuation-based web framework which enables to code a web application like a desktop application, with no need to split its control flow in a multitude of controllers and with the automatic handling of the back, fork and refresh actions from the browser. Its component model and use of the continuation come from the famous Seaside SmallTalk framework. Enjoy! A. Poirier

PyQt3Support r3 - Python bindings for Qt3Support
by Matteo Bertini 24 Sep '08

24 Sep '08

= PyQt3Support - Python bindings for Qt3Support = http://www.develer.com/oss/PyQt3Support *Whats new* - Upgraded to PyQt 4.4.3 - /Deprecated/ annotation support in SIP *What is this?* PyQt3Support is an extension to PyQt4 that adds bindings to Qt's Qt3Support library for usage from the Python language. This is very helpful to migrate existing PyQt3 applications to PyQt4. *Why?* Porting from Qt3 to Qt4 can be tedious and bug-prone. For C++ programmers, Trolltech provides a library, called Qt3Support, that immensely helps. With Qt3Support, a C++ programmer basically only needs mechanical changes to your source code. The library is made of two different parts: A new family of widgets (Q3*) with the same API of Qt3. New member functions (or overloads) within standard Qt4 widgets. For Python programmers, the situation is worse: PyQt4 does not bind Qt3Support to Python. Developers of PyQt3 are forced to manually upgrade their code to PyQt4, class by class. This package fills the gap. By providing a new module PyQt4.Qt3Support, it enables PyQt3 developers to access Trolltech's migration library, and thus upgrade their code much easily and faster, with almost only mechanical changes. It's not a panacea of course: you probably still need minor manual adjustments and supervising, but it can still be of great help. *Download* The (big) full package, containing a patched PyQt4 GPL tree with PyQt3Support. You can basically use this package instead of your PyQt4 pakage. http://www.develer.com/~naufraghi/PyQt3Support/PyQt3Support_PyQt4.4.3_GPL_r… The patch to be applied to a PyQt4 release to add PyQt3Support. http://www.develer.com/~naufraghi/PyQt3Support/PyQt3Support_PyQt4.4.3_GPL_r… Both these packages were produced running the automated script against PyQt4 4.4.3 and PyQt3 3.17.4. If you have a commercial license and you are very paranoid, you probably want to run the script yourself against your own commercial copies of the packages. Otherwise, just grab the patch and apply it, since the result is exactly the same. *Deprecated warnings support* PyQt3Support now uses the new /Deprecated/ SIP annotation. The /Deprecated/ annotation raises a Python Warning when Qt3Support is used, both plain Q3 classes and Qt3Support methods in Q4 classes. You can filter the warning flood with the standard python machinery: warnings.simplefilter('ignore', DeprecationWarning) To use PyQt3Support you need at least a SIP snapshot containing the / Deprecated/ patch or a release >= 4.7.8. http://www.develer.com/oss/PyQt3Support
