Jython 2.5 Beta1 Released!
by Frank Wierzbicki Jan. 9, 2009

Jan. 9, 2009

On behalf of the Jython development team, I'm pleased to announce that Jython 2.5b1 is available for download: http://downloads.sourceforge.net/jython/jython_installer-2.5b1.jar. See the installation instructions here: http://www.jython.org/Project/installation.html. Jython 2.5 Beta1 continues a code cooling period where the number of new features should significantly slow as we concentrate on solidifying Jython 2.5 for an eventual release. I would guess that we will put out about two more betas before we start pushing out release candidates, hopefully in February. This is a beta release so be careful. -Frank

Lepton particle engine 0.8a released
by Casey Duncan Jan. 8, 2009

Jan. 8, 2009

I'm pleased to announce the 0.8 alpha release of Lepton, a high-performance, pluggable particle engine and API for Python. It is designed for creating graphical special effects for games or other visual applications. The engine is designed to be very flexible and does not rely on any other libraries directly. You can use it either with OpenGL (via pyglet, PyOpenGL, wxPython, etc), or with pygame by selecting the appropriate renderer. Examples are provided using pyglet and pygame. Although this is an alpha release, I think it is stable enough to use, and I encourage you to give it a try. The project page is here: http://code.google.com/p/py-lepton/ You can also get it via pypi here: http://pypi.python.org/pypi/lepton/ This release contains no new major functionality, but it has some important bug fixes and performance optimizations. I thought I would release these enhancements now rather than delay them by unrelated feature work. Changes in 0.8a include: - Fixed accuracy of bounce controller so that particles are much less likely to escape from a container domain. (Thanks to dugres for reporting the bug) - Fixed bug in Sphere.intersect() where it would return bogus vectors such as (nan,nan,nan) for stationary particles in some instances. This allowed an improvement to the bouncy example to further prevent errant particles. - Collector controller ported to C - Bounce controller ported to C - Add 2D splode example to demonstrate how to use lepton with the default pyglet OpenGL projection. - Allow basic attribute access for the C controllers from Python (More work is needed here for more complex attributes, like vectors) If you have questions or comments or would like to contribute, you can join the google group at: http://groups.google.com/group/py-lepton-users Enjoy. -Casey

Introduction to Python Class, in Chicago, May 11-13, 2009.
by David Beazley Jan. 7, 2009

Jan. 7, 2009

David Beazley, author of the Python Essential Reference is pleased to announce an "Introduction to Python" class on May 11-13, 2009 in Chicago, Illinois. This course, open to individual enrollment, is a comprehensive hands-on course for programmers, scientists, and engineers who want to master the essential elements of Python programming in order to solve real-world problems in data processing, systems programming, and software integration. This is the same acclaimed course that Dave has taught at more than 30 on-site locations in 2007-2008. The venue for this class is centrally located in the heart of Chicago's downtown financial/theater district. When the class is not in session, you will be just steps away from many of Chicago's most famous parks and cultural attractions. So, come prepared for three days of serious Python instruction and urban exploration. More details about the class can be found at: http://www.dabeaz.com/chicago I hope to see you there! -- Dave Beazley http://www.dabeaz.com
