IMDbPY 4.0 and IMDbPYKit 1.0
by Davide Alberani March 12, 2009

March 12, 2009

IMDbPY 4.0 is available (tgz, deb, rpm, exe) from: http://imdbpy.sourceforge.net/ IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. With this release, support for keywords and top250/bottom100 lists; also, it's now possible to export any data in XML. Many bugs were fixed and other minor improvements are present. Alongside IMDbPY 4.0, the 1.0 release of IMDbPYKit is available. IMDbPYKit is the new web interface of choice of IMDbPY; mostly developed by H. Turgut Uyar, it's based on the Paste Webkit toolkit and it has a lot of nice feature (e.g.: it can output data in both XML and HTML). Platform-independent and written in pure Python (and few C lines), IMDbPY can retrieve data from both the IMDb's web server and a local copy of the whole database. IMDbPY package can be very easily used by programmers and developers to provide access to the IMDb's data to their programs. Some simple example scripts are included in the package; other IMDbPY-based programs are available from the home page.

Regular Toronto Python User's Group on Tuesday the 17th
by Mike C. Fletcher March 12, 2009

March 12, 2009

Topic: OpenGL 3.1: A whole new OpenGL (Mike Fletcher) Further: A preview of the PyCon 2009 presentation on OpenGL 3.1: A whole new OpenGL. We'll be looking at what the legacy-free OpenGL programming model looks like, and how you access it via PyOpenGL. The upcoming OpenGL 3.1 represents the first major backwards incompatible release of OpenGL, and pretty much everything you've read about OpenGL is out the window. The result is a system that is very close to the "metal" of the modern GPU, a set of two (three in newer cards) programmable engines with generic mechanisms for feeding data in and reading it out. Next month Myles Braithwaite will be presenting Google's AppEngine, so be sure to mark the 21st of April on your calendars. As usual, we'll meet at Linux Caffe, at the corner of Grace and Harbord, one block South of Christie station at 7:00, with the meeting starting at 7:15pm. More details on the NextMeeting page on the web-site: http://www.pygta.org Enjoy yourselves, Mike -- ________________________________________________ Mike C.

[ANN] Pyjamas 0.5 Web Widget Set and python-to-javascript Compiler released
by Luke Kenneth Casson Leighton March 11, 2009

March 11, 2009

This is the release of Pyjamas 0.5, a python-to-javascript compiler with an AJAX Web Widget set, for creating python desktop-like applications that run in all major web browsers. http://pyjs.org Pyjamas is NOT "another AJAX framework" where the widgets are predefined, fixed and inflexible. Thanks to the compiler, Pyjamas is a dynamic "framework's framework" where developers can define their own web framework, in Python classes and modules instead of being forced to write code in pure Javascript. The Pyjamas Web Widget set makes it possible for users to develop Rich Media Applications as if they were writing desktop applications, without having to know any Javascript, or even very much HTML. Developing applications using Pyjamas is much more similar to and has far more in common with developing PyQT4 or PyGtk2 applications than it has with "traditional" AJAX web development. Yet, thanks to the applications actually running in a Web Browser, developers get the best of both worlds. For those people who prefer to stick to "true" Desktop development, or who prefer to debug applications in Python rather than rely on the debugging features of Web Browser engines, there is the sister project, Pyjamas-Desktop - http://pyjd.org Pyjamas-Desktop allows the same application source code to be run, unmodified, in both the web browser and as a desktop application. The 0.5 release is a significant functionality update. Additions have been made to the core python-to-javascript compiler such as support for exceptions (try / except), lambda, and a debug option to track and print run-time stack traces, in cases where the deployment of a javascript script debugger is difficult or impossible (IE6 running under Wine). Also, the code-generator has undergone a reorganisation, and now has much better support for local and global variable, function, class and module scopes. Support for Dynamic loading of modules has been added, where each python module now has its own javascript (compiled) "cache" file. This makes it possible to share the modules across the 5 supported platforms, bringing a dramatic reduction in the amount of compiled javascript that is deployed. Also, support for dynamic module loading makes it much clearer how developers may interact with pyjamas-compiled modules from existing applications which already have an AJAX framework in place. Users of previous versions of Pyjamas should note that the UI widget classes have undergone a restructuring, reducing the 4,000 line ui.py into 70 separate small modules. The reorganisation allows applications to undergo a significant reduction in the amount of compiled javascript, by only importing UI Modules that are needed. Reorganisation scripts can be found in contrib/pyjamas_0.4_0.5_upgrade/ that will help in the conversion of existing applications. Also, to make developers' lives easier in both the testing and deployment of pyjamas applications, buildout has been added, along with a standard setup.py. Finally, an experiment is included, which is the beginnings of a way to speed up the execution of standard python, in a similar way to Python-Psyco. The combination of the pyjs python-to-javascript compiler and PyV8 - http://code.google.com/p/pyv8 - becomes a JIT compiler that supports both ARM and i386 assembler. The use of the Google V8 JIT compiler provides a means to dynamically load standard c-based python modules, and the use of pyjs means that the intermediate javascript is actually still human-readable. These are two distinct advantage over pypy, and the third advantage is that the direct translation, instead of going through an intermediary (RPython) means that the full dynamic semantics of the python language are reflected into javascript, and still available. Downloads are available at: http://code.google.com/p/pyjamas/downloads/list https://sourceforge.net/project/platformdownload.php?group_id=239074 http://pypi.python.org/pypi/Pyjamas/0.5 Pyjamas Book is at: http://pyjs.org/book/output/Bookreader.html#Getting%20Started Links to other documentation is on the main site: http://pyjs.org Development and discussion is at: http://groups.google.com/group/pyjamas-dev Subversion Source repository is at: https://sourceforge.net/scm/?type=svn&group_id=239074 IRC Channel is: #pyjamas at irc.freenode.net IRC Logs (thanks to Tim Riker) at: http://ibot.rikers.org/%23pyjamas

[PyCon Tre Italy] CFP reminder - 5 days to deadline
by dialUAZ###UZ#$AAtone＠gWARAmail.com March 9, 2009

March 9, 2009

The CFP deadline is approaching and is now only 5 days away, if you plan to come and would like to give a speech don't wait any longer! ---- For the third year Florence will be hosting the italian edition of PyCon starting from May 8th till May 10th. Unfortunately this year we are a little late in publishing the english version of our CFP. But here we are now. As with last year's edition we will provide real time english-italian and italian-english translation for the main track of the conference and this year's special guest will be none other than Guido himself. Registrations are already open at: http://www.pycon.it/pycon3/registrazione/ where you'll be able to find further information on tickets prices. Conference information is available at our site http://www.pycon.it . The most important deadlines besides those in this CFP are: 13th Apr, End of the Early Bird 4th May, End of Late registrations period. Sponsorships packages are available at this url: http://www.pycon.it/pycon3/sponsorship/ For sponsorship requests contact us at: sponsor(a)pycon.it Here the CFP: Presentations ------ The conference is composed of three parallel tracks: * the *Discovering Python* track will primarily focus on introductory topics about Python libraries, frameworks and technologies; * the *Spreading Python* track will focus both on advanced technical topics and related matters like development methodologies, real-world use cases and management techniques; * the *Learning Python* track will feature a continuous interaction between the speaker and the audience: the speaker will propose a topic and introduce a possible solution, then the talk will dynamically evolve, naturally following questions and notes from the audience. Talks could focus on the following topics (the list is neither exclusive nor exaustive): * vast and/or distributed applications written in Python; * scientific and computationally intensive applications; * interaction with other languages/environments, RPC, services; * web programming and web frameworks; * desktop programming and GUI toolkits; * Python as "scripting" language (system administration, COM, etc...); * Python and databases; * Python as an educational language; Each talk will have one of the following duration: 45, 60 or 90 approximately, inclusive of the time for the audience to enter and leave the room. Please specify which length best fit your contents: some flexibility is available to arrive at the best overall scheduling. ### Community voting Differently from last year, this year the talks' selection process is public: all those who will have bought a ticket no later than March 15 will be able to vote and select the best talk proposals. You can already register at http://www.pycon.it/pycon3/assopy/ to obtain the right to vote. ### How to submit a paper Your talk proposal must be submitted online through Assopy, as soon as it is enabled, by following some simple instructions at http://www.pycon.it/pycon3/assopy/ . ### When, How, and What to submit As a talk proposal, you should just send an abstract with a few text paragraphs about the talk. The evaluation will be easier if you send a detailed description. Once your talk proposal is approved, you'll have to submit the talk slides in PDF format, a few days before the conference opening day. More specific instructions will be available soon. ### A note for non-Italian speakers We warmly welcome and encourage the presence of non-Italian speakers at PyCon Italia. Most talks will be in Italian, though. As last year, we are planning to provide Italian-to-English realtime translation for our guests. We are also like to provide, again, English-to-Italian realtime translation for that part of the audience which is not much familiar with English. **Additional info:** for any questions, please contact us at info(a)pycon.it . ### Important deadlines - March 15th, 2009: Deadline for submitting the talk abstracts for evaluation. - March 29th, 2009: Acknowledge of the talk acceptance, - March 30th, 2009: the talk schedule is published. - May 1, 2009: Deadline for submitting the complete talk slides.
