[ANN] Release 0.61.3 of Task Coach
by Frank Niessink Nov. 19, 2006

Nov. 19, 2006

Hi all, Release 0.61.3 of Task Coach is a bug-fix release that hopefully gets rid of the following bugs: * If saving the TaskCoach.ini file would fail, displaying the error message would fail (too) because the i18n translator had not been imported at that point. * Mac OSX distribution did not start. Upgraded py2app. * Dragging and dropping a task in the task tree view would sometimes drag the wrong task. * Give category dialog focus and select default category title to make it easier to quickly enter categories using the keyboard. * The gdiplus.dll was missing from the Windows distribution. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://taskcoach.niessink.com https://sourceforge.net/projects/taskcoach/ A binary installer is available for Windows XP and a disk image is available for Mac OSX, in addition to the source distribution. Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank Yahoo!

ANNOUNCE: PyGObject 2.12.3
by Johan Dahlin Nov. 18, 2006

Nov. 18, 2006

I am pleased to announce version 2.12.3 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://download.gnome.org/sources/pygobject/2.12/ What's new since PyGObject 2.12.2: - distutils build fixes (Cedric) - documentation updates (John) - gobject.handler_block_by_func and friends now accept methods (Johan, Dima, #375589) - avoid truncating of gparamspec (Yevgen Muntyan, #353943) - set __module__ on gobject derived types (Johan, Osmo Salomaa, #376099) - Ensure exceptions are raised on errors in gobject.OptionGroup (Johan, Laszlo Pandy, #364576) Blurb: GObject is a object system library used by GTK+ and GStreamer. PyGObject provides a convenient wrapper for the GObject+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyGTK, PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject requires GObject >= 2.8.0 and Python >= 2.3.5 to build. -- Johan Dahlin jdahlin(a)async.com.br

itools 0.14.5 released
by "J. David Ibáñez" Nov. 17, 2006

Nov. 17, 2006

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.http itools.uri itools.cms itools.i18n itools.vfs itools.csv itools.ical itools.web itools.datatypes itools.rss itools.workflow itools.gettext itools.schemas itools.xhtml itools.handlers itools.stl itools.xliff itools.html itools.tmx itools.xml This release brings an important feature, the new script "icms-make-package". It will create a Python package, which specializes "itools.cms" to create a custom web application. The purpose of this script is to make it easier for Python developers to get started with "itools.cms". The script comes along with the Quick Start document, which can be found in the itools web site: http://download.ikaaro.org/doc/icms-quickstart/quickstart.html Apart from this new feature, some bugs have been fixed: - In itools.vfs, "vfs.copy" now works when the object being copied is a folder in the filesystem. - In itools.stl, the "not" expressions work now when the character that follows the "not" keyword is a whitespace other than the common space character (e.g. a tab or a new line). Credits: - Hervé Cauwelier added the "icms-make-package" script and fixed the VFS bug; - J. David Ibanez fixed the STL bug.

We are happy to announce a new release of pyFltk, the Python bindings for FLTK. This release supports FLTK-1.1.7 and Python 2.4 and 2.5. FLTK is a lightweight cross-platform GUI toolkit with a very small footprint. pyFltk applications are very simple and intuitive, making it a good choice for small to medium applications that want to get up to speed quickly. Changes in this release include various bug fixes, improved memory management, and the fixing of several compilation issues. Also, some preliminary documentation was added, see test/preface.html. This release can be downloaded from the project home page: http://pyfltk.sourceforge.net Have fun! Andreas http://pyfltk.sourceforge.net

New parallel computing module for Python
by konrad.hinsen＠laposte.net Nov. 16, 2006

Nov. 16, 2006

The latest development release of ScientificPython (2.7), which is available now at http://sourcesup.cru.fr/projects/scientific-py/ contains a new module for parallel computing using a master-slave model: a master process defines computational tasks, and any number of slave processes execute them. The main advantages of this approach are simplicity and the possibility to run a variable number of slave processes. Slave processes can even be killed during execution; as long as at least one slave process remains, the computation will terminate correctly. Here is a very simple example that illustrates parallel computation using the new module: from Scientific.DistributedComputing.MasterSlave \ import MasterProcess, SlaveProcess from Scientific import N import sys class Master(MasterProcess): def run(self): for i in range(5): # request a computation task of type "sqrt" task_id = self.requestTask("sqrt", float(i)) for i in range(5): # retrieve the result from a "sqrt" computation task task_id, tag, result = self.retrieveResult("sqrt") print result class SquareRoot(SlaveProcess): # implement the computation task "sqrt" def do_sqrt(self, x): return (x, N.sqrt(x)) if len(sys.argv) == 2 and sys.argv[1] == "master": master = True elif len(sys.argv) == 2 and sys.argv[1] == "slave": master = False else: print "Argument must be 'master' or 'slave'" raise SystemExit if master: process = Master("demo") else: process = SquareRoot("demo") process.start() The communication between processes is handled by Pyro (pyro.sourceforge.net), which has to be installed as well. Comments are welcome! -- --------------------------------------------------------------------- Konrad Hinsen Centre de Biophysique Moléculaire, CNRS Orléans Synchrotron Soleil - Division Expériences Saint Aubin - BP 48 91192 Gif sur Yvette Cedex, France Tel. +33-1 69 35 97 15 E-Mail: hinsen(a)cnrs-orleans.fr ---------------------------------------------------------------------

Hi all, I'm happy to introduce the release of Amplee 0.3.3, a Python implementation of the Atom Publishing Protocol. This release is a bug fixes but with a few new features as well: * Improved support of the Amazon S3 service as a storage * Support for the Hachoir library which should offer more format supported as members * Fixed the AtomMember class * Improved the potential of the different callbacks on creation, update and deletion of resources. * Added lots of docstrings (still not enough though) * Fixed quite a few bunch of bugs (thanks to David Turner) * Fix the WSGI handler to use the new routing_args spec. * Largely improved the demo as well This release is getting closer to what the final API will look like and I think it's a pretty stable version. == Download == * easy_install -U amplee * Tarballs http://www.defuze.org/oss/amplee/ * svn co https://svn.defuze.org/oss/amplee/ == Documentation == http://trac.defuze.org/wiki/amplee http://www.defuze.org/oss/amplee/doc/html/ == TODO == * Add tests * Remove genser dependency * Improve documentation Have fun, -- Sylvain Hellegouarch http://www.defuze.org
