Shed Skin Optimizing Python-to-C++ Compiler 0.0.10
by Mark Dufour 18 Jan '07

18 Jan '07

Hi all, I have just released version 0.0.10 of Shed Skin, an optimizing Python-to-C++ compiler. It allows for translation of pure (unmodified), implicitly statically typed Python programs into optimized C++, and hence, highly optimized machine language. Many non-trivial benchmarks (ray tracer, chess player, othello player, sat solver, 3 sudoku solvers..) run typically 2-40 times faster than when using Psyco, 12 times on average, and 2-220 times than when using CPython, 45 times on average. Besides many bug fixes, this release adds many error messages for unsupported features, so it should be much easier to try out the compiler and work around problems. Please download this new release from http://mark.dufour.googlepages.com and let me know about any problems/successes. Thanks, Mark Dufour. -- if vars: self.output('; '.join([self.type(var)+' '+name for (name,var) in vars.items()])+';')

[ANN] Release 0.60 of Task Coach
by Frank Niessink 30 Aug '06

30 Aug '06

Hi all, I'm pleased to announce release 0.60 of Task Coach. New in this release: Bugs fixed: * Closing a task file did not reset the 'lastfile' setting. * Selecting Japanese translation would cause error upon next restart. * Task Coach wouldn't quit when the setting 'Minimize window when closing' was set. * Deleting an effort record would throw an exception. Website change: * Added MD5 digests to download page. (See http://taskcoach.niessink.com -> download) What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://taskcoach.niessink.com https://sourceforge.net/projects/taskcoach/ A binary installer is available for Windows XP and a disk image is available for Mac OSX, in addition to the source distribution. Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

Providing take-home materials for attendees is encouraged, and tutorial presenters will receive $50 per student registered for their session (with a minimum payment of $500, and a maximum of $1500). Extra consideration will be given to presenters with prior experience teaching classes or giving conference tutorials. Please provide one reference or evidence of such prior experience (sessions taught at OSCON, EuroPython, local user groups, etc.). PyCon attendees will register for tutorials at extra cost. We reserve the right to cancel tutorials with low attendance; presenters will not be paid for cancelled tutorials. Important Dates =============== * Submission deadline: November 15, 2006 * Acceptance deadline: November 22, 2006 * Cancellation date: January 20, 2007 (for inadequate attendance) Submission Format ================= Proposals should be 250 to 1000 words long (i.e., one to four pages in manuscript format), containing the following information: * Author name(s) * Contact Information * Summary of proposed presentation * Presentation outline * Intended audience (non-programmers, beginning programmers, advanced users, CPython developers, etc.) * (Recommended) At least one previous presentation/teaching engagement reference. E-mail your proposal to <pycon(a)python.org>. ASCII format is preferred, with HTML as a secondary alternative. If you have any questions about submission, please send mail to the conference organizers at pycon(a)python.org.

Call For Proposals: PyCon 2007
by A.M. Kuchling 30 Aug '06

30 Aug '06

PyCon 2007 Call for Proposals ----------------------------- Want to share your expertise? PyCon 2007 is looking for proposals to fill the formal presentation tracks. PyCon 2007 will take place February 23-25 2007 in Addison, Texas, Previous PyCon conferences have had a broad range of presentations, ranging from reports on academic and commercial projects to tutorials and case studies. We hope to continue that tradition this year. As long as the presentation is interesting and potentially useful to the Python community, it will be considered for inclusion in the program. For 2007, we're especially interested in tutorial presentations that will teach conference-goers something new and useful. Can you show attendees how to: use a module? explore a Python language feature? package an application? Important Dates =============== * Submission deadline: October 31, 2006 * Acceptance deadline: November 15, 2006 * Electronic copy deadline: February 15, 2007 PyCon Topics ============ Suitable topics for PyCon presentations include, but are not limited to: * Core Python * Other implementations: IronPython, Jython, PyPy, and Stackless. * Python libraries and extensions * Databases * Documentation * Embedding and Extending Python * Game Programming * GUI Programming * Network Programming * Open Source Python projects * Packaging Issues * Programming Tools * Project Best Practices * Science and Math * Web Programming (Django, Zope, TurboGears, WSGI, ...) Talk Format =========== The preferred length for talks is 30 minutes. You can request a 45-minute slot, but proposals requiring 45 minutes will be reviewed more stringently and tutorial talks will be preferred for these longer slots. Session lengths include time for audience questions. You should budget at least five minutes for questions; for example, a 30-minute talk will be 25 minutes of presentation and 5 minutes of questions. Submission Mechanics ==================== Use the PyCon Online Proposal Submission (http://us.pycon.org/apps07/proposals) to send us your proposals and ideas. Proposal submission will begin on September 15th. If your proposal is accepted, you have the option of including a companion paper along with your presentation. The paper will be published on the PyCon web site. Presentations and papers may be in text (plain or reST), HTML, or PDF; HTML or text are preferred. We suggest, but do not require, that authors place their papers under a Creative Commons license. Please visit the CC 'Choose a License' page (http://creativecommons.org/about/licenses) to select a license that meets your requirements. The HelpForSpeakers wiki page (http://us.pycon.org/TX2007/HelpForSpeakers) has suggestions and advice for speakers. Other Presentations =================== If you don't want to make a formal presentation, you can still bring your new project or idea to PyCon. There will be several Lightning Talk sessions for talks no longer than five minutes. There will also be Open Space for informal and spur-of-the-moment presentations. Open Space consists of thirty-minute blocks that are allocated during PyCon on a first-come first-served basis. These blocks can be used for presentations, round table discussions, hands-on tutorials, or anything else you wish to present.

ANN: Templayer 1.3 - HTML templating library
by Ian Ward 30 Aug '06

30 Aug '06

Announcing Templayer 1.3 ------------------------ Templayer home page: http://excess.org/templayer/ Tarball: http://excess.org/templayer/templayer-1.3.tar.gz About this release: =================== This release includes new documentation and a new auto-reload feature useful for mod_python and web frameworks. Also, the internal template representation was changed to improve performance and consistency, and the HTML generated with HTML Markup is now more standards-compliant. New in this release: ==================== - Added reference documentation and a new tutorial. - Added an auto_reload parameter to Template.__init__ to make the Template.start_file function check and reload a template if it has been modified. This is useful for mod_python and web frameworks with long-lived processes. - Changed the internal representation of the templates to improve performance for large templates and to solve an issue with slots being filled with text that appears to contain another slot that is being filled at the same time. The new implementation no longer allows "%" and "{" characers in slot and layer names. - The Template.missing_slot function is now passed a list of missing slots for a layer. This should improve performance when ignoring a large number of missing slots. - The HTML markup has been adjusted to make its use of <br> and <p> tags more standards-compliant. - HtmlTemplate has been renamed to HTMLTemplate and MarkupException has been renamed to MarkupError. The old names are still provided for backwards compatibility. About Templayer =============== Templayer was created to offer an alternative to the more common ways of generating dynamic HTML: embedding code within the HTML or embedding HTML within code. Instead of mixing HTML and Python, two rich and extremely expressive languages, Templayer adds a small amount of syntax to each and keeps the two separate and coherent. Templayer is released under the GNU LGPL.
