ANN: Kamaelia's Axon-1.0.2 For Series60 Released.
by Michael Sparks 10 Jan '05

10 Jan '05

Axon-1.0.2 For Series60 has been released! This is a modified version of Axon 1.0.2 working (with limited testing - the normal test suite passes) on the Nokia series 60 mobile phones. The key differences are: * The debug subsystem has been disabled * The directory structure has been flattened. What is Axon? ============= Axon is a collection of pure python modules from the Kamaelia project which allow you to build concurrent systems in a compositional manner using communicating python generators. Components are python generators are augmented by inbox and outbox queues (lists) for communication in a CSP like fashion. Put another way this allows you to build complex systems out of small concurrent components in a fashion similar to unix pipelines, except rather than being limited to just stdin/stdout you can have whatever inputs/outputs you desire. (The defaults are inbox/outbox, control/signal) Axon should be relatively feature complete and the API stable, given its design has been fleshed by use in the Kamaelia project. Given Kamaelia components for building network servers, pygame wrappers & vorbis playback have been written using Axon so far, we expect that Axon should be useful for other areas where multiple activities need to be handled within a single thread, whilst allowing the code to remain looking more or less single threaded. Documentation is generated directly from the test suite output. What's new in version 1.0.2-series60? ===================================== * Initial release for series 60 * API documentation has been added (though a work in progress!) * Examples from docs have been fully tested * Changes in distribution structure to simplify transferring onto Nokia mobiles. Licensing ========= Kamaelia is released under the Mozilla trilicense scheme (MPL/GPL/LGPL). Specifically you may choose to accept either the Mozilla Public License 1.1, the GNU General Public License 2.0 or the Lesser General Public License 2.1. Proprietary licensing details available upon request. Where can I get it? =================== Axon is a sub-project of the BBC R&D Kamaelia project, which means Axon is downloadable from http://sourceforge.net/projects/kamaelia/ Web pages are here: http://kamaelia.sourceforge.net/Docs/Axon.html http://kamaelia.sourceforge.net/ (includes info on mailing lists) ViewCVS access is available here: http://cvs.sourceforge.net/viewcvs.py/kamaelia/ Best Regards, Michael. -- Michael.Sparks(a)rd.bbc.co.uk British Broadcasting Corporation, Research and Development Kingswood Warren, Surrey KT20 6NP This message (and any attachments) may contain personal views which are not the views of the BBC unless specifically stated.

Chicago Python Users Group: Thu 13 Jan Meeting
by Ian Bicking 10 Jan '05

10 Jan '05

The Chicago Python User Group, ChiPy, will have its next meeting on Thursday, 13 January 2005, starting at 7pm. For more information on ChiPy see http://chipy.org This month the topic will be An Introduction To Jython, presented by Brian Zimmer. Jython is an implementation of Python that runs on the Java Virtual Machine. Brian Zimmer has been using and developing Jython for over 4 years. He is the author of zxJDBC, the Python DB API implementation for Jython as well as recently taking over primary maintenance for the Jython project. Brian recently receive a grant from the Python Software Foundation for his project "Moving Jython Forward." There will also be time to chat, and many opportunities to ask questions. We encourage people at all levels to attend. Location -------- This month we will be meeting in the Monadnock Building Conference Room 826, 53 W Jackson St, in downtown Chicago. This is immediately adjacent to the blue line and an easy walk from all Metra stations and the CTA red line, at the corner of Jackson and Dearborn. Because the meeting is held after-hours for the building, we need to provide a list of attendees. Please send your name (as it appears on your ID) to tobis (at) mailbag dot com (if you aren't sure you'll be able to come, send your name anyway). If you drive, aim for the Congress Parkway exit from the Ryan (I-90/94) or the east end of the Eisenhower (I-290). About 5 blocks east and 2 blocks north once you enter the street grid is the entrance you are looking for. (Alternatively, exit Lakeshore at Congress and head west about 5 blocks.) There are numerous paid parking lots in the area. If you're adamantly opposed to parking structures sometimes a meter can be found, especially on the south side of Congress around Printer's Row. Refreshments will be provided, but unfortunately there will be no live network connection, so if you have something you want to show, bring it along on your laptop. About ChiPy ----------- We meet once a month, on the second Thursday of the month. If you can't come this month, please join our mailing list: http://lonelylion.com/mailman/listinfo/chipy

[ANN] PyScript 0.5 released
by cochrane＠physics.uq.edu.au 10 Jan '05

10 Jan '05

PyScript is a python module for producing high quality postscript graphics. Rather than use a GUI to draw a picture, the picture is programmed using python and the PyScript objects. Some of the key features are: * All scripting is done in python, which is a high level, easy to learn, well developed scripting language. * All the objects can be translated, scaled, rotated, ... in fact any affine transformation. * Plain text is automatically kerned. * You can place abritrary LaTeX expressions on your figures. * You can create your own figure objects, and develop a library of figure primitives. * Output is publication quality. LICENSE: Released under the GPL The major change in this release is a complete rewrite of the Path object. The internals have completely changed and there have been some incompatible changes with previous versions but it's now much closer to what was envisaged for the object. There have also been many bug fixes and minor other improvements. For details see the PyScript web page: <a href="http://pyscript.sourceforge.net">pyscript.sourceforge.net</a>. <P><A HREF="http://pyscript.sourceforge.net">PyScript 0.5</A> - a python module for producing high quality postscript graphics; rather than use a GUI to draw a picture, the picture is programmed using python and the pyscript objects.

ANN: Paranoia 1.2 released (Port of old BSD Game)
by Sean P. Kane 10 Jan '05

10 Jan '05

Paranoia 1.2 has been released! What is it? ======== Paranoia 1.2 is a port to Python from C of the old "paranoia" console game that used to be distributed with the bsd-games package, but has long since been removed. I ported this from C to Python as an exercise in learning Python and because I was suffering a serious bout of boredom and nostalgia. Paranoia is based on the role playing game, by the same name, that was very popular amoung a certain set during the 1980's and is making a resurgance today. Note that this release is as identical to the oringal game as I could make it within reason. I'm not a C coder, so I may have missed some functionality, but I don't think so. If you notice any errors or have any suggestions on cleaning up the Python code, please feel free to contact me. Where can I get it? ============== paranoia.py and the original c code that it is based on are currently avaliable from: http://homepage.mac.com/spkane/python/ Enjoy! >

man python always amazes me. i was scratching an itch for a simple online gallery system and once again i'm amazed at how fast i could write a respectable gallery system and with a small amount of python code. less than 300 lines of code but it's useful enough that i thought i should stick it up on sourceforge. here it is: http://pix.sf.net

itools 0.6.0 released
by "J. David Ibáñez" 06 Jan '05

06 Jan '05

What is it? * itools.uri -- an API to manage URIs, to identify and locate resources. * itools.resources -- an abstraction layer over resources that let to manage them with a consistent API, independently of where they are stored. * itools.handlers -- resource handlers infrastructure (resource handlers are non persistent classes that add specific semantics to resources). This package also includes several handlers out of the box. * itools.xml -- XML infrastructure, includes resource handlers for XML, XHTML and HTML documents. Plus the Simple Template Language. * itools.i18n -- tools for language negotiation and text segmentation. * itools.workflow -- represent workflows as automatons, objects can move from one state to another through transitions, classes can add specific semantics to states and transitions. * itools.catalog -- An Index & Search engine. What's new? Resources - Now "get_resources" is an iterator that returns a resource (not a name) at a time. - Memory folders provide "get_atime". Handlers - Add the methods "get_handler_names", "get_handlers" and "has_handler". - The methods "get_resource", "has_resource", "set_resource", etc. have been removed. Access them throug the "resource" attribute, or use the equivalent handler methods ("get_handler_names", etc). - Now text handlers only must define the method "to_unicode", which now accepts the optional parameter encoding. - The methods "__str__" and "__unicode__" have been removed. Use instead "to_str" and "to_unicode". - Serialization and de-serialization code has been moved from "xml.Schema" to "handlers.IO". Now the code serializes and de-serializes to and from byte strings. XML - The architecture has been cleaned and simplified, specially for attributes, whose API has changed. - The new method "traverse2" makes "walk" obsolete. Simple Template Language - The "stl:if" and "stl:attributes" expressions accept the new "not" operator. This change makes the "stl:ifnot" statement obsolete. Catalog - Now the catalog follows the load/save logic. As a side effect the index and unindex operation has been speeded up but a factor of 2, aproximately. Workflow - Remove the "__init__" method from the "WorkflowAware" class to avoid conflicts with handler classes. Now the method "enter_workflow" must be called explicitly. Documentation - Re-write part of the introduction. - Re-organize the handler chapters. Explain some things for the first time, explain other things better.
