Release: DirectPython 0.4
by Heikki Salo 23 May '06

23 May '06

After a month of work a new version of DirectPython is now available at http://directpython.sourceforge.net/ What is it? ----------- DirectPython is a C++ extension to the Python programming language which provides basic access to DirectX (9.0c) API, including Direct3D, DirectSound, DirectShow and DirectInput. The full distribution is very easy to install and it includes many samples and documentation that show the basics of DirectPython programming. No additional packages are needed. Whats new in 0.4.0? ------------------ Too many changes to be listed in here. There are few changes that can break existing code, but they should be relatively easy to fix. There are no new samples, but a lot of useful stuff has been added and many bugs have been squashed. Requirements ------------- A Windows operating system with Python 2.4.x and DirectX 9.0c installed.

IPlib 1.0
by alberanid＠libero.it 23 May '06

23 May '06

IPlib 1.0 can be downloaded (tgz, rpm, deb and exe) from: http://erlug.linux.it/~da/soft/iplib/ IPlib is a Python module useful to convert amongst many different notations and to manage couples of address/netmask in the CIDR notation. Some example scripts (ipconv.py, nmconv.py and cidrinfo.py) are included. In this release: iteration over CIDR object; comparison operators for addresses, netmasks and cidr objects; augmented and reflected arithmetic operations for addresses. Moreover some bugs were fixed and the test suite improved. -- Davide Alberani <alberanid(a)libero.it> [PGP KeyID: 0x465BFD47] http://erlug.linux.it/~da/

Toronto Area Python Users Group (PyGTA) meeting tomorrow, 7pm at Linux Caffe
by Mike C. Fletcher 22 May '06

22 May '06

We'll be holding our regular meeting @ Linux Caffe tomorrow evening. My proposed topic of the evening: Web development frameworks, structures, experiences and suggestions We have an embarrassment of riches in Python, yet no single Web Framework has emerged as being a reasonable "obvious choice" for all web development projects. What do we as developers want to see from a web framework, what comes close, where does it fall down. We'll try to keep presentation-style stuff to 5-10 minutes for any given framework so that we can have a lively discussion about features, approaches, assumptions and suggestions for how to improve on the frameworks. My own interest is more in how the frameworks help or hinder when "programming in the large", but hearing about quick-and-dirty project support is likely to be just as interesting to everyone. Linux Caffe is located at Grace and Harbord, just South of Christie station. It has free wifi, so if you have online demonstrations of web frameworks, feel free to bring a laptop. I'll have a Linux Laptop available for those who want to show us the shock and awe of their favourite framework, but keep in mind that we want to hear what's *wrong* with it too, not just sales pitches (and no "it's perfect, it's just not widely known enough" cop-outs). If you'd like to do a couple of minute presentation on your favourite or current framework, let me know and I'll schedule people to talk. We'll try to keep the whole thing civil, of course, this is Python, after all. Maps and the like available off the Wiki page: http://web.engcorp.com/pygta/wiki/NextMeeting Have fun all, Mike -- ________________________________________________ Mike C.

Guido was awarded the Free Software Foundation Award in 2002 and Dr.Dobb's 1999 Excellence in Programming Award. Guido works at Google and spends half of his time on Python. [2] Jim Hugunin (Microsoft) is the creator of numerous innovations that take Python into new application domains. Jim's most recent project, IronPython integrates Python into Microsoft's .NET runtime. Jim's previous project, Jython is Python for the Java runtime and was the second production-quality implementation of Python. Before that, Jim's Numeric Python adapted Python to the needs of number crunching applications. Jim works at Microsoft adapting the .NET runtime to the needs of dynamic languages like Python.

[ANNOUNCE] Thirty-first release of PythonCAD now available
by Art Haas 19 May '06

19 May '06

Hi. I'm pleased to announce the thirty-first development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The latest release features improvements to the entity splitting code and a new split operation, automatic entity splitting. The splitting code has been rewritten which fixed several bugs while making the code simpler and clearer to understand. The new autosplitting code is a feature that, when activated, will make the program split existing entities in a drawing when a newly added point lands on the entity. Various code cleanups are also present in this release, including the ability to set and later change the default style values for the different entities used within PythonCAD. Finally, a number of bug fixes and other code improvements are present in this release. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program! Art Haas -- Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. -Thomas Jefferson to James Smith, 1822
