Shed Skin Optimizing Python-to-C++ Compiler 0.0.10

by Mark Dufour

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()])+';')

LDTP 0.6.0 released !!!

by A Nagappan

Issue IX - 28 September 2006 We are proud to announce the release of LDTP 0.6.0. This release features number of important breakthroughs in LDTP as well as in the field of Test Automation. This release note covers a brief introduction on LDTP followed by the list of new features and major bug fixes which makes this new version of LDTP the best of the breed. Useful references have been included at the end of this article for those who wish to hack / use LDTP. About LDTP ========== Linux Desktop Testing Project is aimed at producing high quality test automation framework and cutting-edge tools that can be used to test Linux Desktop and improve it. It uses the Accessibility libraries to poke through the application's user interface. The framework also has tools to record test-cases based on user events in the interface of the application which is under testing. We strive to help in building a quality desktop. This release features an all new TCP interface of the server which, is covered briefly below. Recording has taken new heights and the code is much organized now. More bug fixing and documentation changes. Whats new in this release... ============================ + Remote TCP based execution Tests can, now, be carried out from a remote terminal. LDTP Clients can connect to the new TCP interface and run tests with-in the box that is running the server. This kind of interface comes handy for testing applications running in small devices. This interface is contributed by "Palm Source". + Recording using LDTP This new version of LDTP features a recorder tool which would help in generating automation scripts automatically by recording user events. This would greatly reduce the time required for creating and maintaining automation scripts. Thanks to Venkateswaran ('whacko'), Harishankaran ('sp2hari') and Theyagarajan ('Taggy') for making this happen. For more information on this please refer to http://ldtp.freedesktop.org/wiki/RecordHOWTO + Bug fixes This version includes loads of bug fixes to address important issues like memory leak, API functionality, accessibility compatible issues etc., For a detailed list please refer to release notes section of our project site hosted in http://ldtp.freedesktop.org.

[ANN] Spasmoidal 0.1.0 - Asynchronous I/O with Python 2.5 Extended Generators

by Doug.Fort＠gmail.com

"...from little towns with strange names like Smegma, Spasmodic, Frog, and the far-flung Isles of Langerhans". Someone on SourceForge has a project that includes the name 'spasmodic' so I'm using the name spasmoidal. But this code will always be spasmodic to me. Asynchronous I/O (and other tasks) proceeding in fits and spasms The SpasmodicEngine selects tasks (spasmoids) from a (heapqueue based) priority queue. The tasks are Python 2.5 extended generators (some call them coroutines: PEP 342). The engine calls task.send() with an appropriate argument. One of the library of tasks is Pollster. Pollster calls poll() with for tasks that are waiting I/O. Tasks that are ready for I/O are fed to the priority queue. Spasmodic provides an efficient way to manage a large number of sockets and/or files. Other processing works well too, if it can be subdivided into brief spasms.

Django session at Pune Python meet on 30th September

by Sandy

Pune Python meet organized by PythonThreads.com is scheduled on 30th September. The main purpose of the meet is to introduce Django to Python web framework developers and encourage them to use it in their daily tasks. Amitabh Jain will speak on Django. In the IndicThreads.com Java meet, Amol Raje will talk about Portlets. Speakers :- Amitabh Jain is an IT professional with more than 8 years of experience in companies like Infosys and Vertex. He has done his graduation in Computer Science from Pune University followed by MBA from IIM, Ahmedabad. Over the years, he has worked with various technologies in different technical and managerial capacities. Currently, he is involved in setting up a startup that is focused on executing projects using accelerated development frameworks like Django. He first started dealing with Python in 2000, when he was evaluating Zope for one of the projects at Infosys in Bangalore. After that he has been using Python in various projects. Amol Raje is currently working as a business analyst with the Global functions team in HSBC GLT. He was earlier with ITC Infotech in Bangalore and has over 5 years of industry experience. Guido van Rossum, the creator of Python, recently commented on Django. He said, "People keep asking me to pick one, and I like Django because I like the way its authors run their project : They really 'get' open-source development.". He is pretty clear that he is not trying to force the "there should be only one way to do it" philosophy on the world of Python web frameworks. Well, Guido prefers Django, you can judge the importance of Django from his comments. Django session details :- * Introduction to Django (5 mins) * Mapping MVC concepts in Django (5 mins) * A walkthrough of a simple Django application (15 mins) * ORM in Django (5 minutes) * A look at a more complex Dnago application (30 minutes) Session will be followed by an open discussion on Django.

Be Paid to Attend PyCon 2007!

by Jeff Rush

PyCon 2007, to be held in Dallas at the same location as in 2006, is coming up and we need instructors to fill Tutorial Day on Feb 22. Last year we had tutorials for: Python 102 Internet Programming with Python Getting Started with wxPython Text & Data Processing Plone Rapid Bootcamp Using Databases with Python A Game-Free Introduction to PyGame Getting Started with the Twisted Framework Agile Development and Testing in Python Classes are half-day affairs (3-hours with a 15-min break) and net the instructor $500-$1500 (depending upon enrollment). One or two of those would easily cover your expenses for attending PyCon and then some. And since tutorials are held the day BEFORE the main conference, you won't miss any talks either. Tutorials have more stringent requirements than talks, often providing class handouts and finely tuned presentations. For this reason we want the best. And if you're short on topic ideas, or a potential student who would like a specific topic covered, check out our wiki page at http://us.pycon.org/TX2007/TalkIdeas Instructors, email your (plain text) proposals, 250 to 1000 words long, to <pycon(a)python.org>. The deadline for submissions is _Nov 15_ with an acceptance decision by Nov 22. Your proposal should cover: * Instructor name(s) * Contact Information * Summary of proposed presentation * Presentation outline * Intended audience (non-programmers, beginning programmers, advanced users, core Python developers, etc.) * (Recommended) At least one previous presentation/teaching engagement reference So get cranking and let us see your best. Jeff Rush PyCon 2007 Co-Chair

Zope 3.3.0 released!

by Philipp von Weitershausen

On behalf of the Zope 3 development team I'm proud to announce the final Zope 3.3.0 release. There were no changes since the 3.3.0 release candidate. Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. Cleanup of the Zope 3 packages has continued to ensure a flexible and scalable platform. We continued the work on making the transition from Zope 2 to Zope 3 by making Zope 2.10 use even more of the Zope 3 packages. But the transition is far from complete yet. **You can't run Zope 2 applications in Zope 3.** Downloads --------- http://www.zope.org/Products/Zope3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt file of the distribution. The binary installer is recommended for Windows. Zope 3.3 requires Python 2.4.1 to run, Python 2.4.3 is recommended. It does **NOT** work with Python 2.5 yet. You must also have zlib installed on your system. Most Important Changes Since Zope 3.2 ------------------------------------- - Provided a new component registry API that allows multiple component registries to be combined more flexibly than before. See 'zope.component.interfaces.IComponentRegistry' for more information. - Greatly simplified local-component registration. See 'zope.component.interfaces.IComponentRegistry' for more information. - Moved many packages out of zope.app to make them easier to use outside of Zope. - Change the session credentials plugin to make it configurable in which fields it looks for the credentials. - Added a new API for collating text. You can now adapt a locale to 'zope.i18n.interfaces.ILocales.ICollator'. You can then use that to sort strings, such as menu entries, in a locale-specific fashion. - A new 'zope.annotation.factory' helper function that makes it easier to create annotations. Also added a README in 'zope.annotation' which explains how to use it. - Added a more complete set of widgets for fields that use iterable sources. These widgets now mirror the set provided by vocabulary-based fields. - Added a cleaner and more robust API to testbrowser for setting file-upload data. - Deprecated several ZCML directives: * factory * vocabulary * content (as an alias to the class directive) * modulealias * renderer:renderer - The 'browser:layer' directive and the 'ILayer' interface has been deprecated. Registering layers has become obsolete, layers should be created as interfaces extending 'IBrowserRequest'. - The 'browser:skin' directive has been deprecated. Skins should be created as interfaces extending 'IBrowserRequest' and can be registered using a simple 'utility' directive. - The 'ISkin' interface has been renamed to 'IBrowserSkinType'. For a complete list of changes see the 'CHANGES.txt' file.
