[ANNOUNCE] Twenty-sixth release of PythonCAD now available
by Art Haas 21 Oct '05

21 Oct '05

I'm pleased to announce the twenty-sixth 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 twenty-sixth release includes a few interface enhancements. More of the menus can be activated from the keyboard, and stretch/move operations now accept entry box values when performing either task. A significant amount of work has been applied to the internal routines used for storing the entities in a drawing, the result of which required numerous changes throughout the code. The primary change was adjusting the Quadtree search and storage routines to handle the case where multiple instances of equivalent entities are stored. In earlier releases of PythonCAD this scenario would result in strange errors if it were to occur. As is always the case, a large number of smaller bug fixes and code enhancements are also 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

Greater Toronto Area Python User's Group (PyGTA) has a new venue
by Mike C. Fletcher 21 Oct '05

21 Oct '05

Paul Baranowski was ambitious enough to arrange a recurring booking at the Linux Caffe, so as of October the 25th we will be meeting on the fourth Tuesday of the month at Linux Caffe (326 Harbord at Grace, South of Christie station). Linux Caffe is a geek-friendly venue with everything we should need for our meetings, including a projector. I'm still looking for speakers for Tuesday. Feel free to contact me if you have a presentation or lightning talk you think would interest the group. We're not the most formal group in the world, and we're always interested in new members. So, if you program in Python (or just want to) and live in or around Toronto, you *need* to be at 326 Harbord this upcoming Tuesday at 7pm. Have fun, Mike ________________________________________________ Mike C. Fletcher Designer, VR Plumber, Coder http://www.vrplumber.com http://blog.vrplumber.com

ANN: WebStack 1.0 released
by Paul Boddie 20 Oct '05

20 Oct '05

WebStack 1.0 has finally been released! What is it? ----------- >From the introductory text: WebStack is a package which provides a simple, common API for Python Web applications, allowing such applications to run within many different environments with virtually no changes to application code. In other words, it's a Python package which provides classes for Web programming to applications and higher-level frameworks, but where you get to deploy the same code regardless of whether you're running on mod_python, CGI, Zope, Twisted or any of the other supported environments. Some people may find WebStack too low-level for writing applications; this is intentional - WebStack does not pretend to be a "full stack" Web solution, but seeks to offer standardised functionality to such solutions. How did it come about? ---------------------- Once upon a time, the Web-SIG was formed to discuss possible standards for Python Web programming. Early enthusiasm [1,2,3] failed to yield much more than the now-famous PEP 333 [4,5], but building on surveys of existing projects such as the "Python Web Frameworks Overview" [6], WebStack 0.2 was released [7] partly to discover how different the APIs and features of certain existing projects really were, whilst providing a common API for them all. Where can I get it? ------------------- WebStack is available via the Python Package Index: http://www.python.org/pypi/WebStack (Packages for Ubuntu may be made available. Contributions of other packages are welcome!) Have fun with WebStack! Paul [1] http://mail.python.org/pipermail/web-sig/2003-October/000003.html [2] http://mail.python.org/pipermail/web-sig/2003-October/000009.html [3] http://mail.python.org/pipermail/web-sig/2003-November/000331.html [4] http://mail.python.org/pipermail/web-sig/2003-December/000394.html [5] http://www.python.org/peps/pep-0333.html [6] http://www.boddie.org.uk/python/web_frameworks.html [7] http://www.python.org/pypi?:action=display&name=WebStack&version=0.2

FunkLoad 1.2.0 released
by Stefane Fermigier 20 Oct '05

20 Oct '05

FunkLoad 1.2.0 is out. About FunkLoad: FunkLoad is a open source functional and load web tester, written in Python, whose main use cases are functional and regression testing of web projects, performance testing by loading the web application and monitoring your servers, load testing to expose bugs that do not surface in cursory testing, and stress testing to overwhelm the web application resources and test the application recoverability, and writing web agents by scripting any web repetitive task, like checking if a site is alive. Changes since 1.1.0: * Credential and Monitor services have been refactored they are now true unix daemon service, controllers are now in pure python (no more bash scripts). * Switching from distutils to setuptools using EasyInstall_, installing FunkLoad is now just a question of ``sudo easy_install funkload``. * Moving demo examples into the egg, just type ``fl-install-demo`` to extract the demo folder * Several bugs have been fixed. More info: http://funkload.nuxeo.org/ Grab it: http://funkload.nuxeo.org/funkload-1.2.0.tar.gz or http://cheeseshop.python.org/pypi/funkload Best regards, S. -- Stéfane Fermigier, Tel: +33 (0)6 63 04 12 77 (mobile).
