________________________________________________________________________ eGenix EuroPython 2008 Presentations & Videos ________________________________________________________________________ We have uploaded our EuroPython 2008 presentations to our website. Learn the concepts behind the Python DB-API and how to design large-scale applications. This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/EuroPython-2008-Presentations.html ________________________________________________________________________ INTRODUCTION The EuroPython Conference is the one of the premier conferences for Python & Zope users and developers. This year it was being held from the 7th to 9th July in Vilnius, Lithuania. eGenix was one of the founding members of the EuroPython conference team and played a major role in organizing the first EuroPython conference in the year 2002. Since then we have attended every EuroPython conference to meet up face-to-face with the people from the Python & Zope communities and have given regular talks at these conferences. ________________________________________________________________________ TALKS AT EUROPYTHON 2008 We gave the following two talks at the conference. The presentations are available for viewing and download from our Presentations and Talks section: http://www.egenix.com/library/presentations/ As special feature, we have added talk videos in addition to providing the slide PDFs. You can view the talks online if you have the Adobe Flash Player 8 or later installed. * Using the Python Database API The Python Database API (DB-API) is a specification of a module interface that allows interfacing from Python to a relational database. The talk gives a high-level introduction to the concepts used in the Python DB-API and relational databases in general. Connection, cursors and transactions are discussed, and their use in Python database applications is explained. * Designing Large-Scale Applications in Python Python is widely and somewhat inaccurately referred to as a scripting language. While Python is an ideal platform for small scripting tasks, it does in fact cover all the concepts needed for large scale object oriented application development. However, complex applications bring different challenges. This talk draws on eGenix' many years experience with large scale application development using Python as central implementation language and provides a cookbook approach to many of the the problems you face when designing and organizing complex application frameworks.

ANNOUNCE: wxPython 2.8.8.1
by Robin Dunn 21 Jul '08

21 Jul '08

Announcing ---------- The 2.8.8.1 release of wxPython is now available for download at http://wxpython.org/download.php. This is a minor bugfix release with several fixes for problems discovered in the 2.8.8.0 release. Source code is available, as well as binaries for Python 2.3, 2.4 and 2.5, for Windows and Mac, as well some packages for various Linux distributions. A summary of changes is listed below and also at http://wxpython.org/recentchanges.php. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.3+, in most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. Changes in 2.8.8.1 ------------------ wx.richtext: Added wrappers for the RichTextPrinting and RichTextPrintout classes. Make it easier to replace the check box images used in the CheckListCtrlMixin class. Fixed bug in wx.ScrolledWindow when child focus events caused unneccessary or incorrect scrolling. Fixed a bug in wx.GridBagSizer where hidden items were not ignored in part of the layout algorithm. Several other bugs also fixed. Added builds for Ubuntu Hardy (8.04) -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

RELEASED Python 2.6b2 and 3.0b2
by Barry Warsaw 18 Jul '08

18 Jul '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team and the Python community, I am happy to announce the second beta releases of Python 2.6 and Python 3.0. Please note that these are beta releases, and as such are not suitable for production environments. We continue to strive for a high degree of quality, and these releases are intended to freeze the feature set for Python 2.6 and 3.0. From now until the planned final releases in October 2008, we will be fixing known problems and stabilizing these new Python versions. You can help by downloading and testing them, providing feedback and hopefully helping to fix bugs. You can also use these releases to determine how changes in 2.6 and 3.0 might impact you. ONLY ONE MORE BETA RELEASE IS PLANNED, so now is a great time to download the releases and try them with your code. If you find things broken or incorrect, please submit bug reports at http://bugs.python.org For more information and downloadable distributions, see the Python 2.6 website: http://www.python.org/download/releases/2.6/ and the Python 3.0 web site: http://www.python.org/download/releases/3.0/ See PEP 361 for release schedule details: http://www.python.org/dev/peps/pep-0361/ Enjoy, - -Barry Barry Warsaw barry(a)python.org Python 2.6/3.0 Release Manager (on behalf of the entire python-dev team) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQCVAwUBSIARKHEjvBPtnXfVAQL7AQQAjPSbfKz2Oh/au/hPzS4x2IR5/R6FVe+g o9UYrONNRKJ14UHpbZRzvIvw/4G3PdpzzGxjYFIhVGEesEGJnMzT3YdkMHt4NW9d HOZxL3hseGbTdpUJPCsIkNG+4hX7iuY3NSV81Z75LGAL4tqbooGqwwUslXMT5f8s lRrZUcBRKZ0= =ju6s -----END PGP SIGNATURE-----

[pygtk] ANNOUNCE: PyGObject 2.15.1
by Johan Dahlin 16 Jul '08

16 Jul '08

I am pleased to announce version 2.15.1 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/2.15/ There are two new significant features in this release series, initial bindings for GIO. Note that these are not complete, please report missing API in Bugzilla so we know what people are missing. Codegen has been moved from PyGTK and can now be used without depending on GTK+, which should be useful for GObject based libraries. What's new since PyGObject 2.15.1? - Rename pygtk-codegen-2.0 to pygobject-codegen-2.0 to avoid conflicting with PyGTK (Paul Pogonyshev) 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 glib >= 2.8.0 and Python >= 2.3.5 to build. GIO bindings require glib >= 2.16.0. -- Johan Dahlin jdahlin(a)async.com.br

[ANN] netaddr for Python
by David Moss 16 Jul '08

16 Jul '08

This is a post to announce the creation of a brand new library for Python called NetAddr. It is a network address manipulation library released under the BSD license. It supports several of the most common address formats (IPv4, IPv6 and MAC and IEEE EUI) as well as several aggregate notations such as CIDR. An effort has been made to provide an API that is as Pythonic as possible. NetAddr is now in beta (latest release is 0.3.1) and is currently being actively developed. Developers and testers are needed to assist in improving the quality and availability of network library support for Python which is distinctly lacking when compared with other popular interpreted languages such as Ruby and Perl. NetAddr is an attempt to redress this imbalance to some extent. Home page: http://netaddr.googlecode.com/ Features include :- - Flexible support for the representation of multiple address types using the a common set of network address classes - Address objects emulate standard Python types dependent on context. They behave as strings, integers, lists, compare and sort numerically, etc - Efficient representation of large address spaces via several aggregate types. Also supports arbitrary network address ranges that don't necessarily fall on strict bit boundaries - Generators are used throughout for efficient iteration, indexing and slicing of network address spaces and ranges - Testing on both big and little endian architectures has carried out throughout the initial development of this library - A lot more features are planned over coming releases Requirements :- - Python 2.3 or higher (doesn't support Python 3.0 ... yet) For more information, downloads and examples, please visit :- http://netaddr.googlecode.com/ Share and enjoy, David Moss
